RU2772921C1 - Simulator for practicing the skill of cyst enucleation in laparoscopic surgery - Google Patents

Abstract

FIELD: medical technology.

SUBSTANCE: invention relates to medical models and can be used to practice the skill of cyst enucleation in laparoscopic surgery. The simulator includes a platform, four rectangular trapezoidal racks, removable elastic bands, a clamp and two rubber balls. The platform is made of polymethylmethacrylate. A metal clamp is fixed 8 cm from the side face and 5 cm from the front face. Four rectangular trapezoidal racks are fixed to the platform with an offset of 4.5 cm from the corners of the platform. Triangular cutouts are made 1 cm from the upper base of the racks on their outer sides. Between the racks, removable elastic bands are stretched to simulate a zone of surgical intervention with limited access, in the center of which a rubber ball is fixed with a clamp with the possibility of removal using a laparoscopic dissector and laparoscopic scissors, into which a second ball inflated with air is invaginated.

EFFECT: ensuring the repeated development of the laparoscopic surgery skill.

Description

The simulator for developing the skill of cyst enucleation in laparoscopic surgery belongs to the field of medicine, namely, to medical training models for acquiring and practicing the manual skill of cyst enucleation in laparoscopic surgery by medical students, residents and surgeons.

When developing the proposed device, the goal was to create a simulator for practicing the skill of cyst enucleation in laparoscopic surgery, which would be easy to manufacture, allow you to repeatedly practice the skill and have high economic profitability.

The simulator for developing the skill of cyst enucleation in laparoscopic surgery consists of a polymethyl methacrylate platform measuring 16*16 cm and 0.5 cm thick, on which a metal clamp 2 cm wide and 1 cm long is fixed 8 cm from the side face and 5 cm from the front face. Four rectangular trapezoidal racks made of polymethyl methacrylate 0.5 cm thick, 5 cm high, the length of the lower base 2 cm and the upper base 0.5 cm are fixed with an indent from the corners of the platform by 4.5 cm. A triangular cutout is made 1 cm from the upper base of the rack 4 mm deep and 3 mm wide on the outside of the rack (Fig. 1). The simulator comes with 5 rubber bands and 2 inflatable rubber balls with a diameter of 10 cm.

When working on this simulator, it is preferable to use 2 laparoscopic dissectors (Traditional Maryland) and laparoscopic Metzenbaum scissors.

At the first stage, it is proposed to use 2 dissectors (Traditional Maryland) to alternately pull 5 rubber bands between 4 posts with cutouts, which creates a zone of surgical intervention with limited accessibility (Fig. 2). Further, at the second stage, it is necessary to fix the ball in the place of its ligation in the center of the surgical intervention zone using a metal clamp, which, before starting the task, was invaginated into a ball and inflated with air to a diameter of 10 cm (Fig. 3). The trainee is asked to remove the outer balloon using a laparoscopic dissector and laparoscopic scissors, without violating the integrity of the inner balloon filled with air. This exercise simulates the enucleation of a cyst of a parenchymal organ or organs of the reproductive system without damaging its own walls.

The proposed simulator for developing the skill of enucleation of cysts of parenchymal organs and organs of the reproductive system in laparoscopic surgery has the following advantages:

• allows you to practice a number of stages and skills, such as:

1. the sequence of stages of cyst enucleation;

2. precision and care in performing manipulations;

3. development of attention;

4. work with a rotator on a laparoscopic manipulator;

5. ambidexterity;

• versatility, as the simulator can be used in any laparoscopic box;

• the possibility of multiple use, since the only consumable material is stationery gum and rubber balls that imitate the walls and cavity of the cyst;

• the simulator is easy to manufacture;

• low cost of components and parts of simulators makes it cost-effective for educational institutions and for personal use.

The laparoscopic surgical method of enucleation of ovarian, kidney, and liver cysts occupies a leading position in the treatment of this pathology, since visualization during laparoscopy significantly reduces the possibility of damage to organ tissues, in addition, manipulations are performed through small punctures of the anterior abdominal wall, which contributes to the rapid healing of wounds and reduction of pain. syndrome. This confirms the relevance and high probability of using the simulator to develop the skill of cyst enucleation in laparoscopic surgery in the individual and collective training of doctors and residents in surgical hospitals, at the advanced training departments of surgical doctors and at simulation centers.
