Abstract

FIELD: teaching aids in medicine.

SUBSTANCE: gynecological simulator includes a platform on which a rod with a fixation of the uterus model and a uterus model are installed. The platform is made of polymethyl methacrylate, at the base of the platform there is a rod made of elastic and equipped with a fixation of the uterus model, a hinged adapter with a quick-clamping nut is placed on the rod, which, together with the rod and the fixation of the uterus model, imitates the uterine manipulator of the Clermont-Ferrand model. At the top of the rod, a uterine model retainer is installed, made of plastic, spring-loaded, adjustable with a quick-clamping nut. The swivel adapter is positioned with the ability to adjust the position, visualize the back surface, change the angle of inclination and fix the uterine model. The model of the uterus is made of foam rubber and includes the body, fallopian tubes, ovaries and the ovary's own ligament.

EFFECT: ensuring the development of the skill of extracorporeal and intracorporeal endoscopic suture during laparoscopic surgery on the uterus and uterine appendages.

Description

The gynecological simulator belongs to the field of medicine, namely to the development of laparoscopic manual skills in operative gynecology.

A 3D model of the pelvic cavity in women is known from the prior art, which is used to model the general type of surgery for a gynecological tumor (Patent CN 210402879 U, 04/24/2020), a 3D model of the female pelvis, used to model the anatomy of the female small pelvis and explain the course of operations with gynecological operations, including a pelvic model, is fixedly connected to the block in the upper part of the model on the left and right sides, fixed to the plate, which is connected to the cylinder and the bearing installed in it, fixed on the basis of the small pelvis model.

This model has only an informational function, illustrating the anatomy of the female small pelvis and showing the scope of surgical interventions for gynecological pathology. A 3D model of the pelvic cavity in women, used to model the general type of surgery for a gynecological tumor, does not allow practicing practical skills and stages of operations on the pelvic organs, which is a significant drawback.

When developing the proposed device, the goal is to create a gynecological simulator that will allow cadets to practice the skill of extracorporeal and intracorporeal endoscopic suture during laparoscopic operations on the uterus and uterine appendages, have a simple design and have high economic profitability.

The solution to this goal is a gynecological simulator, consisting of a platform of polymethyl methacrylate measuring 16 * 16 cm with a thickness of 0.5 cm, on which an elastic rod with a fixation of the uterus model and a model uterus.

An elastic rod 12 cm long, 1 cm thick, with a fixation of the uterus model and a swivel adapter imitates the Clermont-Ferrand uterine manipulator. At the top of the rod there is a plastic spring retainer of the uterus model 6*2 cm with gripping surface dimensions of 3*2 cm, adjustable with a quick-clamping nut. A swivel adapter with a quick-lock nut is located 6 cm from the top of the rod, which allows the cadet to adjust the position of the uterus, visualize the posterior surface of the uterus, change the angle of inclination and fix the model in the required position.

The model of the uterus is made of foam rubber and includes: the body of the uterus 8 * 5 * 5 cm in size, the fallopian tubes 10 cm long, the ovaries 3.5 * 2.5 * 2 cm and the ovary's own ligament.

When working on this simulator, the cadet is offered, for example, to perform laparoscopic tubectomy (Fig. 3), to work out the skill of suturing the uterus after performing myomectomy with localization on the anterior surface (Fig. 4), posterior surface of the uterus (Fig. 5), in the fundus ( Fig. 6) and cervix (Fig. 7).

The proposed gynecological simulator can be widely used in teaching and training operational manual skills in gynecology, as it has the following advantages:

• allows you to work out a number of techniques, such as laparoscopic tubectomy, extracorporeal and intracorporeal suture of the uterus after perforation, myomectomy of various localization, resection of the ovary, suture of the vaginal stump;

• simulation of the Clermont-Ferrand uterine manipulator, allows you to work out operations in difficult anatomical areas, such as the cervix, posterior surface of the uterus and Douglas space;

• the use of the simulator is possible in any laparoscopic box;

• available consumables that mimic anatomical structures;

• simple manufacturing technology;

• low cost of components and parts of the simulator makes it cost-effective for educational institutions and for individual training.
