FAQ

What are the common problems and solutions in urological surgical instruments?

Common problems and solutions in urological surgical procedures can be discussed from multiple aspects, including instrument operation, equipment use, complication prevention and treatment, etc. The following is a detailed analysis:

1. Common problems and solutions in instrument operation
(1) Operation blind spots and instrument limitations
Problem description:
In traditional open surgery or laparoscopic surgery, due to the angle and length limitations of the instrument, operation blind spots often occur, resulting in certain areas being unable to be reached.

Solution:
The use of a robotic-assisted surgical system can effectively solve this problem. The wrist-type instrument of the robotic surgical system can achieve 360-degree rotation, expanding the surgical operable range, and has a tremor control function, which improves the accuracy and flexibility of the surgery.

(2) Bleeding and carbonization problems in laser surgery
Problem description:
During traditional laser surgery, there may be no bleeding, no scab, and no carbonization. However, green lasers are almost not absorbed by water due to their highly selective absorption of oxygenated hemoglobin, which may cause intraoperative bleeding.

Solution:
Using disposable medical laser fiber in combination with green laser surgical system can effectively reduce intraoperative bleeding and carbonization problems.

2. Common problems and solutions in equipment use
(1) Risk of gas embolism
Problem description:
In laparoscopic surgery, if the optical clamp is directly inserted without pneumoperitoneum, it is feasible, but it is recommended to avoid it due to the high risk. In addition, gas embolism is one of the serious pulmonary complications that may lead to rapid heart failure and death.

Solution:
Preoperative preparation and anesthesia instructions should be strictly followed to ensure that the patient is in the correct position, and emergency measures should be taken immediately when gas embolism is suspected, such as releasing the pneumoperitoneum, increasing oxygen intake, placing a central venous catheter, and performing cardiopulmonary resuscitation.

(2) Improper management of laparoscopic equipment
Problem description:
With the widespread application of laparoscopic surgery in urology, the management system of laparoscopic equipment in some hospitals is still not perfect, nurses are not proficient in operating and managing the equipment, and there is a phenomenon of disorderly storage of equipment.

Solution:
Establish a sound laparoscopic equipment management system and regularly train medical staff to ensure that they can operate and manage the equipment proficiently to avoid delays in surgery or equipment failures caused by improper management.

3. Prevention and treatment of complications
(1) Postoperative infection
Problem description:
Surgical site infection (SSI) in urology is one of the most common complications. How to prevent related infections is crucial to the treatment, quality of life and prognosis of patients.

Solution:
Strictly abide by aseptic operation procedures, use antimicrobial drugs for preoperative and postoperative prevention, and strengthen postoperative care and monitoring to promptly detect and treat the source of infection.

(2) Urinary fistula and other complications
Problem description:
Complications such as urethral spasm, bladder neck spasm, and urinary fistula may occur after urological surgery.

Solution:
For the repair of the urethra and bladder neck, experienced surgeons are used to perform tissue repair and safe connective tissue anastomosis, and timely internal cavity drainage is performed. For complex situations such as ureteropelvic junction obstruction, pyeloplasty or tongue mucosal ureteroplasty is used to achieve tension-free anastomosis.

Summary
Through the above measures, common problems in urological surgery can be effectively dealt with, and the success rate of surgery and the quality of patient prognosis can be improved. Robot-assisted surgical systems, disposable medical laser fibers, and strict equipment management and measures to prevent complications are all important development directions in the current field of urology.

What are the application effects and patient satisfaction of robot-assisted surgical systems in urology?

The application effects and patient satisfaction of robot-assisted surgical systems in urology are generally positive. The following is a detailed analysis:

Surgical effect:

Precision and stability: The robotic surgical system has high stability and precision, which can reduce errors in surgery, thereby improving the success rate and safety of surgery.

Minimally invasive advantages: Robot-assisted surgery has less trauma and faster recovery time than traditional laparoscopic surgery. For example, in partial nephrectomy, the warm ischemia time of robotic surgery is shorter, the patient's renal tissue is less damaged, and the recovery state is better.
Adapt to a variety of complex surgeries: The robotic surgical system is suitable for surgeries with organ preservation and function retention requirements, such as radical prostatectomy, partial nephrectomy, etc.
Patient satisfaction:

Quick recovery: Due to the minimally invasive nature of robotic surgery, patients have a shorter postoperative recovery time, which reduces hospital stay and rehabilitation costs, thereby improving patient satisfaction.
Precision treatment: The high-precision operation of the robotic surgery system makes the surgery more precise, reduces the risk of complications, and further enhances patient confidence and satisfaction.
Clinical application cases:

The Provincial Hospital Affiliated to Shandong First Medical University has completed 1,000 robot-assisted surgeries, demonstrating its breadth and effectiveness in practical applications.
The Department of Urology of Peking University First Hospital has performed nearly 2,000 robotic surgeries, further verifying the feasibility and advantages of robotic surgery in clinical practice.
The application effect of the robot-assisted surgery system in urology is significant, and patient satisfaction is high, mainly due to its high precision, stability and minimally invasive advantages.

What are the results of a comparative study between disposable medical laser fiber and traditional green laser surgical system in reducing bleeding and carbonization?

The results of a comparative study between disposable medical laser fibers and traditional green laser surgical systems in reducing bleeding and carbonization are as follows:

Reducing bleeding:

Disposable medical laser fibers have the functions of laser cutting and laser coagulation, which can accurately cut tissues and reduce bleeding. In addition, this fiber can also transmit laser energy to microsurgical instruments to help doctors perform delicate surgical operations, thereby reducing surgical trauma and bleeding.

Green laser systems also show significant effects in reducing bleeding. For example, green lasers have a photoselective effect on red, and during treatment, blood vessels in proliferating prostate tissues are first blocked, so that there is basically no bleeding or very little bleeding during treatment. When green lasers are used to remove superficial bladder tumors, intraoperative bleeding is also less.
Carbonization (vaporization):

Green lasers can vaporize diseased tissues and interact with red blood cells to cause coagulation, thereby preventing tissue bleeding. This shows that green lasers perform well in carbonization.

Although the carbonization effect of disposable medical laser fibers is not directly mentioned, they have laser cutting and laser coagulation functions and may also have certain carbonization capabilities.
Both disposable medical laser fiber and traditional green laser surgical system show good effect in reducing bleeding, and green laser system also has significant performance in carbonization.

What are the prevention strategies for gas embolism in laparoscopic surgery, and how to evaluate their effectiveness?

The prevention strategies for gas embolism in laparoscopic surgery mainly include the following points:

Verify the position of the pneumoperitoneum needle: Before gas injection, the position of the pneumoperitoneum needle must be carefully verified. If symptoms such as hypotension, increased heart rate, peripheral cyanosis, aggravated second heart sound, and mild rumbling occur, be alert to the possibility of gas embolism.

Intraoperative monitoring: Since artificial pneumoperitoneum may cause the patient's head to be high and feet to be low or head to be low and feet to be high during surgery, which may affect the respiratory and circulatory functions, therefore, the anesthesiologist should be assisted in monitoring blood pressure, heart rate, blood oxygen saturation, etc. during the operation, so as to detect and deal with it in time.

Correct operation method: Correct operation should be performed during the process of establishing pneumoperitoneum to reduce the occurrence of gas embolism.

For the evaluation of its effectiveness, you can refer to the research on the difference between PaCO2 and EtCO2 as a monitoring indicator. This study explored whether the PaCO2-EtCO2 difference can be used as a monitoring indicator for carbon dioxide gas embolism during laparoscopy, and used for the diagnosis and efficacy evaluation of carbon dioxide gas embolism. The results showed that the two patients with gas embolism mainly showed a mild decrease in SpO2 and a transient increase in end-tidal carbon dioxide (EtCO2). This shows that the occurrence and treatment effect of carbon dioxide gas embolism can be effectively diagnosed and evaluated by monitoring the PaCO2-EtCO2 difference.

Specific case analysis of surgical delays or instrument failures caused by improper management of urological laparoscopic equipment.

Specific case analysis of surgical delays or instrument failures caused by improper management of urological laparoscopic equipment can be discussed from the following aspects:

Equipment startup failure: According to, laparoscopic equipment may encounter power failures at startup, such as damaged power plugs, power cords, or internal circuit board problems. This may cause the equipment to fail to work properly before the operation begins, causing delays in surgery.

Application of digital nursing management model:
It is mentioned that by adopting a digital nursing management model, the error rate of preoperative laparoscopic instrument preparation, the number of parts missing, and the satisfaction of doctors can be effectively reduced. This shows that if the management is not good, such as nurses cannot operate and manage instruments skillfully, and there are phenomena such as disorderly storage of instruments, it will directly affect the smooth progress of the operation.

Examples of adverse events in the operating room: It is mentioned that before and after the operation, the instruments and items are incorrect, the sutures are ejected due to improper operation, the direction is unclear and difficult to find, the integrity of the instruments is neglected, the accessories are short or the inspection is neglected before the operation, all of these may lead to accidents during the operation and affect the progress of the operation.

Classification and maintenance guide for laparoscopic instruments:
It emphasizes the importance of the performance status, cleaning, disinfection and sterilization effect of laparoscopic instruments. Unqualified laparoscopic instruments may bring many risks such as infection, tissue damage and surgical errors. Therefore, correct disassembly, installation, standardized operation and preventive maintenance are the key to avoiding unnecessary loss and failure.

Detailed nursing management and psychological care:
The study shows that detailed nursing management combined with psychological care can significantly reduce the error rate of laparoscopic instrument preparation and the loss rate of parts in the operating room, which further illustrates the impact of improper management on surgery.

Application of project management in improving the image stability of laparoscopic equipment in operating rooms:
It is mentioned in the report that after the improvement of project management, the image failure rate of laparoscopic equipment in operating rooms dropped from 1.30% before the improvement to 0.61%, which shows that scientific management tools or methods for systematic management of laparoscopic equipment in operating rooms can effectively reduce the failure rate and reduce surgical risks.

Improper management of laparoscopic equipment in urology may lead to delayed surgery or instrument failure, including equipment startup failure, irregular management process, instrument preparation errors, neglect of instrument integrity, shortage of accessories, improper maintenance and other problems.

What is the latest research progress in postoperative infection prevention measures?

The latest research progress in postoperative infection prevention measures mainly focuses on the following aspects:

Application of diluted povidone iodine: According to Wang Haoyu's research, diluted povidone iodine is highly regarded by scholars in infection prevention after joint replacement.

Monitoring and removal of Staphylococcus aureus: More than 60% of postoperative infections are caused by Staphylococcus aureus, so monitoring and removing Staphylococcus aureus carried by patients has become an important task in preventing infection after joint replacement. Scholars from the Department of Orthopedics at Mount Sinai School of Medicine in the United States conducted a literature review and proposed the latest concept of monitoring and prevention of Staphylococcus aureus infection after hip and knee replacement.

WHO Guideline Update: The global guidelines issued by WHO recommend that antibiotics should not be used prophylactically after surgery. This is an internationally accepted standard based on a large number of latest research results.

Consensus on Prevention of Postoperative Infection after Spinal Fixation: The Spinal Infection Group of the Spine and Spinal Cord Committee of the Chinese Rehabilitation Medicine Association has released the latest expert consensus on the prevention of surgical site infection after spinal fixation. With the improvement of awareness and in-depth research on spinal surgical site infection, as well as the accumulation of more high-quality clinical research evidence, some current views have been updated.

Postoperative blood sugar control and body temperature management: Postoperative blood sugar control (180 mg/dL or lower) within 18-24 hours after surgery is recommended, but too low blood sugar levels may increase the risk of postoperative infection and lead to poor prognosis. Maintaining body temperature (35.5°C or above) and optimizing tissue oxygen saturation are also important for preventing postoperative infection, especially for patients requiring mechanical ventilation.

Film covering technology: Film covering technology has been used for at least 50 years. It uses medical surgical films to cover the surgical site to prevent bacterial colonization of skin tissue and reduce the incidence of SSI.

Anti-infection coating internal fixation: Some results have been achieved in preventing the formation of bacterial biofilm on the surface of internal fixation and dead bone, but more innovation is needed in new methods to improve infection prevention after fracture internal fixation.

Rational use of antimicrobial drugs: Reports from the Japanese Society of Surgical Infections and the Japanese Society of Chemotherapy discussed methods for preventing and treating infections after surgery, including continuous use of methicillin and intranasal spraying of mupirofen, which can significantly reduce the wound infection rate of methicillin-resistant Staphylococcus aureus.

The latest research progress in postoperative infection prevention measures includes the application of a variety of methods and technologies, such as diluted povidone-iodine, monitoring and removal of Staphylococcus aureus, updated WHO guidelines, consensus on infection prevention after spinal fixation, blood sugar control and temperature management after surgery, film covering technology, anti-infection coating internal fixation, and rational use of antimicrobial drugs.
