FAQ

How do minimally invasive surgical instruments help reduce the risk of surgical complications?

Minimally invasive surgical instruments help reduce the risk of surgical complications in a variety of ways:

Reduce surgical trauma: Minimally invasive surgery often uses smaller incisions, such as 0.5cm to 1cm operation holes, which greatly reduces damage to surrounding tissues, thereby reducing the risk of postoperative infection and bleeding. For example, in minimally invasive spinal surgery, smaller incisions reduce blood loss and reduce the risk of postoperative infection.

Improve surgical precision: Minimally invasive technologies such as robotic surgery can help doctors perform more delicate operations in a smaller space, reduce the possibility of misoperation, and thus reduce the incidence of complications. In addition, advanced instruments such as minimally invasive ultrasonic bone knives can complete soft tissue separation and precise osteotomy under minimally invasive conditions, further reducing surgical complications.

Shorten hospital stay: Because minimally invasive surgery is less invasive and recovers quickly, patients usually need a shorter hospital stay. This not only reduces complications associated with hospitalization (such as infection and thrombosis), but also speeds up the patient's recovery process.

Promote healing: Minimally invasive surgical instruments such as fascia closures can effectively connect tissues together, prevent infection, and promote wound healing. This rapid healing also helps reduce postoperative complications.

Reduce intraoperative bleeding: Minimally invasive surgery has a wide field of view, clear blood vessels, and less intraoperative bleeding, which directly reduces the risk of postoperative complications. For example, in minimally invasive spinal surgery, reducing intraoperative bleeding is one of the key factors in reducing the risk of complications.

Reduce postoperative pain: Since minimally invasive surgery has less trauma, postoperative pain is less severe, and the patient's overall comfort is improved, which also indirectly reduces other complications caused by pain.

Minimally invasive surgical instruments significantly reduce the risk of surgical complications by reducing surgical trauma, improving surgical accuracy, shortening hospital stays, promoting healing, reducing intraoperative bleeding, and reducing postoperative pain.

What is the specific mechanism of minimally invasive surgical instruments in reducing postoperative infection and bleeding?

The specific mechanism of minimally invasive surgical instruments in reducing postoperative infection and bleeding is as follows:

Reduce surgical trauma: Minimally invasive surgical instruments reduce the area of ​​surgical trauma by using tiny incisions for surgery. This reduced trauma area can significantly reduce the risk of postoperative bleeding and reduce the exposure of tissues in the body, thereby reducing the possibility of surgical infection.

Shorten surgical time: Minimally invasive surgery is usually shorter than traditional surgery. For example, in neuroendoscopic minimally invasive surgery, compared with conventional craniotomy hematoma removal, minimally invasive surgery can shorten the operation time, reduce intraoperative bleeding, and improve the hematoma removal rate, thereby improving the patient's prognosis.

Reduce inflammatory response: Some studies have shown that minimally invasive surgical techniques (such as "tubeless" techniques) can reduce inflammatory response by reducing systemic and local hyperresponsiveness during surgery. This mechanism of reducing inflammatory response helps to improve the patient's long-term survival after surgery.

Reduce surgical complications: Minimally invasive instrument-assisted surgical methods can improve operating methods and reduce the occurrence of surgical complications. For example, micro-incision cholecystectomy has achieved minimally invasive status by reducing surgical trauma and complications.

Maintain intestinal flora balance: Although this mechanism is mainly aimed at abdominal surgery, oral administration of double triple live bacteria before surgery can minimize the occurrence of postoperative infectious complications. Its mechanism is attributed to the maintenance of intestinal flora and the restriction of intestinal bacterial translocation, which represents the enhancement of immunity and the simultaneous reduction of systemic stress response.

How does minimally invasive surgical technology improve surgical precision, and what are the specific techniques or tools?

Minimally invasive surgery technology improves surgical accuracy through a variety of specific technologies and tools, mainly including the following aspects:

Robotic surgical system: Robotic surgical systems such as the da Vinci robot can magnify tissue images 10-15 times through high-definition binocular lenses and 3D endoscopic cameras, thereby greatly improving the accuracy and stability of the operation. In addition, the robotic surgical system can also assist doctors in formulating personalized prosthesis implantation plans based on the patient's CT scan data and prosthesis model data before surgery, and achieve high-precision operations through precise positioning and registration technology during surgery.

Visual detection and tracking algorithm: The visual detection and tracking algorithm of minimally invasive surgical instruments analyzes the images transmitted by the endoscope and extracts the position of the tip of the surgical instrument in the image, thereby providing surgical navigation. This technology can greatly improve the accuracy and success rate of surgery.

Artificial intelligence (AI) technology: The application of AI technology makes minimally invasive surgery more accurate. AI can provide support from multiple aspects such as disease prevention, risk assessment, auxiliary diagnosis to auxiliary surgery, helping doctors make more accurate decisions.

Intelligent surgical navigation and positioning system: This system enhances the doctor's multi-level perception of the surgical environment and the human-machine collaboration ability of surgical operations by improving the accuracy and robustness of real-time spatial positioning of images, patients, and instruments, thereby improving the accuracy of the operation.

Robot-assisted spinal surgery: Using robotic technology, surgeons can place screws and other implants with extremely high precision, which is particularly suitable for complex spinal fusion surgery.

What detailed data support the impact of minimally invasive surgery on patients' hospital stay?

The impact of minimally invasive surgery on patients' hospital stay is supported by the following detailed data:

Minimally invasive surgery generally allows patients to get out of bed 6-8 hours after surgery, eat after anal gas discharge 12-24 hours, be discharged from the hospital 3-5 days, and basically recover after one week.

In the laparoscopic minimally invasive and traditional surgical treatment of pediatric extraperitoneal hernia, the hospital stay of the minimally invasive surgery group was significantly shorter than that of the traditional surgery group.

The hospital stay for ultra-minimally invasive precise visual ablation of the thyroid gland is only 1-2 days.

Comparison of the efficacy of laparoscopic minimally invasive surgery and traditional laparotomy in pelvic inflammatory masses showed that the hospital stay in the laparoscopic group was significantly shorter than that in the laparotomy group.

For minimally invasive surgery, walking within 8 hours after surgery was associated with a shorter hospital stay (-53%, 95% CI -55% to 52%).
In patients undergoing colectomy, minimally invasive surgery prolonged the operation time by more than 30 minutes compared with open surgery, but significantly reduced intraoperative bleeding, and the intestinal function recovered quickly, and the hospital stay was significantly shortened.
The hospital stay of patients in the observation group who underwent minimally invasive surgery for intertrochanteric fractures in the elderly was significantly shorter than that in the control group.

What is the mechanism of action of fascial closure in promoting wound healing?

The mechanism of action of fascial closure in promoting wound healing is mainly reflected in the following aspects:

Fast and uniform suturing: fascial closure can achieve fast and uniform suturing, reduce bleeding and tissue damage during surgery, and is conducive to postoperative wound healing.

Prevent infection: Traditional suturing methods can only suturing epidermal wounds, which is easy to cause wound infection. The fascia closure device can completely close the defects of the myofascia and peritoneum of each layer of the puncture hole, effectively prevent puncture hole hernia after laparoscopic surgery, and thus reduce the risk of infection.

Standardized operation: The fascia closure device provides a standardized operation process, which is used for various patient puncture holes through controllable suturing, ensuring the safety and consistency of suturing.

Reduce surgical trauma: Compared with traditional open surgery, minimally invasive fascia closure devices have the advantages of less trauma, faster recovery, and less bleeding, which directly promote the rapid healing of wounds.

What are the techniques or methods to reduce postoperative pain in minimally invasive surgery?

In minimally invasive surgery, the techniques or methods to reduce postoperative pain mainly include the following aspects:

Choose appropriate analgesics: For minimally invasive surgery, and (or) nonsteroidal anti-inflammatory drugs (NSAIDs) are preferred for analgesia. If the effect is not good, opioid receptor partial agonists can be given as needed.

Individualized pain management: According to different gynecological minimally invasive procedures, individualized analgesia mode is selected, and the minimally invasive concept is integrated throughout the entire medical behavior to achieve the best medical effect.

The concept of accelerated recovery after surgery (ERAS): adopt perioperative treatment measures with evidence-based medical evidence to reduce or lower the psychological and physiological traumatic stress of surgical patients, maintain organ function, and promote the recovery of physiological function in patients in a short time.

Emotional nursing intervention: treat the condition through pain nursing knowledge and other operation methods to relieve the patient's pain in time. For example, in the minimally invasive interventional operating room, combining emotional nursing intervention can effectively improve the patient's pain outcome.

Advantages of minimally invasive technology itself: minimally invasive surgery can complete the operation without or only with a small skin incision through advanced medical equipment and technology, such as laparoscopes and thoracoscopes, which significantly reduces surgical trauma and helps to reduce the patient's pain and postoperative recovery time.
