What are the applications of hysteroscopic equipment in minimally invasive gynecological surgery and their impact on surgical results?

The application of hysteroscopic equipment in minimally invasive gynecological surgery and its impact on surgical results are mainly reflected in the following aspects:

Hysteroscopic surgery is a typical minimally invasive surgery. Through the hysteroscope, uterine distension medium and strong cold light are introduced into the uterine cavity, electrodes are inserted, and intrauterine lesions are electrically removed under direct vision.

This technology has gradually replaced the traditional, more traumatic open abdominal hysterectomy, with the advantages of less trauma, less intraoperative bleeding, and fewer complications.

Hysteroscopic equipment can clearly observe various changes in the patient's uterine cavity and make effective diagnoses.

For example, the narrow-band light imaging system can enhance the observation of the texture of the mucosal vascular network and improve the diagnostic sensitivity of endometrial cancer and atypical hyperplasia.

In addition, the application of B-ultrasound and laparoscopy can provide guidance for hysteroscopic surgery to prevent missed cutting and uterine perforation.

The use of hysteroscopic surgery can shorten the operation time and reduce the risk of excessive absorption of perfusion medium.

The tissue rotary cutting system uses mechanical rotary cutting to achieve the removal of lesion tissue on the basis of electrical energy work, which improves the efficiency of surgery.

In addition, ultra-thin hysteroscopes can perform endometrial polyp and cervical polyp removal surgery without anesthesia. Although there may be problems such as poor imaging, the overall safety and effectiveness of the surgery are improved.

Hysteroscopic surgery not only brings patients benefits such as less trauma, low cost, short hospitalization time, and rapid postoperative recovery, but also preserves the uterus and improves reproductive prognosis.

This makes hysteroscopic technology a revolutionary event with milestone significance in the history of gynecological development.

Although complications of hysteroscopic surgery are rare, they still need to be taken seriously, such as uterine perforation, adhesions, and uterine bleeding.

Preventive measures include strictly following the doctor's instructions for medication, regular review, and avoiding excessive fatigue.

In recent years, with the advancement of technology and the accumulation of doctors' experience, the incidence of complications in hysteroscopic surgery has decreased.

With the advancement of science and technology, the advancement of image display and communication technology has made television hysteroscopy a reality and widely used, and it is expected to be safer, more effective, simpler, minimally invasive, and microscopic. In addition, non-destructive or less-destructive high-tech instruments such as ultrasound imaging and magnetic resonance imaging are becoming more and more popular, which may replace diagnostic hysteroscopy, but not surgical hysteroscopy.

How to ensure that the instruments used are both safe and effective during minimally invasive gynecological surgery?

When performing minimally invasive gynecological surgery, ensuring that the instruments used are both safe and effective requires comprehensive consideration of multiple aspects. The following are detailed measures:

Preparation and inspection of instruments:

Before surgery, medical staff need to check whether the packaging of diagnostic and treatment instruments and other items is intact and undamaged and within the validity period.
Surgical instruments should be sterilized after high pressure before use to ensure their sterility.

Training and protection of operators:

Medical staff should wear hats, surgical masks and sterile gloves, wear sterile surgical gowns, and perform hand hygiene and hand disinfection.

Nurses and operators need to receive professional training to master the performance, operation principles and precautions of surgical instruments to ensure that they can use surgical instruments professionally and in a standardized manner.

Maintenance and maintenance of equipment:

A complete instrument maintenance system should be established, and a special instrument maintenance team should be set up to regularly maintain and repair surgical instruments and replace consumable parts in a timely manner.

When using a monopolar electrocoagulator, disposable negative plates should be used as much as possible, and the negative plates should be attached to the fullness of the muscles, in full contact with the skin, to reduce the risk of injury.

Management during surgery:

During the operation, nurses need to closely observe changes in the condition, pay attention to monitoring and adjusting the CO_2 pneumoperitoneum machine, and avoid complications.

Circulating nurses should be familiar with the requirements for body position and inclination of the operating table at different stages of the operation, and adjust them in a timely manner.

During the operation, blood stains and excess instruments should be cleaned up in a timely manner, and the number of instruments should be counted again before closing the body cavity to ensure consistency.

Postoperative treatment and disinfection:

The cleaning, disinfection and maintenance of hysteroscopic equipment and instruments are the key to ensuring the success of the operation and preventing complications. After cleaning, the endoscope and accessories need to be monitored biologically

Use disinfectants and equipment that meet the regulations for disinfection, avoid using organic solutions for scrubbing, and use pressure steam sterilization, glutaraldehyde immersion or ethylene oxide and other methods

Special precautions:

Avoid using peritoneal lavage fluid containing Na+, and avoid contact with directly grounded metal or equipment during surgery. Use non-metallic probes

Injuries caused by improper use of electrosurgical instruments often occur in monopolar electrocoagulation operations, while bipolar electrocoagulation is safer. Therefore, when using a monopolar electrocoagulator, disposable negative plates should be used as much as possible

What is the impact of the use of auxiliary tools in minimally invasive gynecological surgery on the success rate of surgery?

The use of auxiliary tools in minimally invasive gynecological surgery has a significant impact on the success rate of surgery. The following is a detailed analysis:

Da Vinci Robotic System: The application of the Da Vinci Robotic System in gynecological surgery has shown its advantages. For example, a study based on Beijing Anzhen Hospital affiliated to Capital Medical University showed that when using the da Vinci robot for transoral minimally invasive surgery (TORS), the assistant needs to be familiar with the surgical steps and operating rules to ensure tacit cooperation with the surgeon, thereby improving surgical efficiency. In addition, the da Vinci robot system can provide three-dimensional images to help the surgeon observe the surgical area more clearly and reduce intraoperative bleeding and complications.

Robot-assisted surgery (RAS): RAS also shows certain advantages in the treatment of gynecological tumors. Although its safety and efficacy data are not sufficient, studies have shown that for patients with early ovarian cancer, RAS can provide disease control, survival rate and recurrence rate comparable to open surgery, with shorter hospital stay and lower complication rate. However, for patients with high-grade ovarian cancer, the application of RAS still needs to be cautious due to the high risk of peritoneal rupture and limited field of view.

Laparoscopic surgery: Laparoscopic surgery, as a standard minimally invasive procedure, is widely used in hysterectomy. Although robot-assisted surgery shows a lower incidence of intraoperative complications in some cases, its high cost limits its clinical promotion. Therefore, laparoscopic surgery is still the standard procedure for hysterectomy for benign diseases.

Preoperative evaluation and teamwork: Successful minimally invasive surgery not only depends on advanced auxiliary tools, but also requires detailed preoperative evaluation and close cooperation between team members.

For example, in the da Vinci robot transoral minimally invasive surgery, the assistant needs to independently complete the installation and connection of the bedside robotic arm, the placement of the mouth opener and the exposure of the tumor, which requires the assistant to have high professional skills and rapid response ability

Application in specific situations: Robot-assisted surgery shows certain feasibility when dealing with recurrent ovarian cancer, but it is not applicable in patients with obvious cancer spread.

This further illustrates the need to make reasonable judgments based on specific circumstances when selecting auxiliary tools.

The use of auxiliary tools in minimally invasive gynecological surgery plays an important role in improving the success rate of surgery. These tools not only improve the accuracy and safety of the operation, but also shorten the recovery time of patients.
