RU233368U1 - A simulator for mastering the technique of preparing male testers - Google Patents

Abstract

The utility model relates to veterinary medicine, in particular, to surgery, and can be used as a simulator for mastering the technique of preparing male testers. The use of male testers is the most effective and closest to natural conditions method of identifying females in heat. Many of the existing simulators cannot ensure mastering the technique of performing such an operation.

The claimed simulator consists of a leather bag simulating the scrotum, inside of which are placed two rubber chambers filled with filler, simulating the testicles, and in them are two rubber tubes, simulating the spermatic cord and the vas deferens, the testicles are also placed in two rubber chambers, simulating the muscular-elastic membrane, fascia and the general vaginal membrane.

The simulator works as follows: The scrotum is treated with an antiseptic solution. Cuts 4-5 cm long are made on each testicle. The skin, muscular-elastic membrane, fascia and common vaginal membrane in the area of the caudal surface of the scrotal neck are successively dissected. After opening the common vaginal membrane, the vas deferens is clearly visible at the bottom of the wound against the background of the spermatic cord. The vas deferens is grasped with anatomical tweezers, and a piece of it 1-2 cm long is resected with scissors, and the stumps are released into the wound. The wound of the common vaginal membrane is sutured with a furrier's suture. A nodal suture is applied to the skin wound. The wound is treated with an antiseptic solution.

Description

The utility model relates to veterinary medicine, in particular, to surgery, and can be used as a simulator for mastering the technique of preparing male testers. The use of male testers is the most effective and closest to natural conditions method of identifying females in heat. Many of the existing simulators cannot ensure mastering the technique of performing such an operation.

A surgical simulator for applying intestinal sutures is known, comprising a base and fixation devices located on it. The base is made in the form of a table-table, on which two soft intestinal clamps are located, one of which is fixed immovably, and the other is able to move along rails, between which, on the sides of the table-table, several clamp-holders are located, and on the side of the movable intestinal clamp, perpendicular to it, a cylinder for putting on the intestine is located, which is connected to a manometer through a tube with an air pump located on it (Patent of the Russian Federation for Utility Model No. 6192. Authors Sandakov P. Ya. et al., 1998). The disadvantage of this simulator is the impossibility of performing a surgical operation on animals. A simulator for mastering the technique of basic surgical skills is known, which contains a support platform consisting of three parts, one of which contains a reservoir with a silicone cushion fixed to the support platform, consisting of three layers simulating the skin, subcutaneous fat and a layer of muscle fibers, and two triangular-shaped faces made of organic glass, simulating the edges of the surgical wound, between which silicone rods are stretched, fixed on clamps rigidly attached to the support platform. The other part of the platform contains a reservoir with silicone, which imitates the muscle layer. The third part, simulating an artery and a vein, is made of two silicone tubes stretched over the support platform and fixed on both sides on blocks rigidly fixed to the platform. In this case, the silicone layer simulating the skin, subcutaneous tissue and muscle fibers, as well as the muscle layer with tendons and nerve fibers, has a color that corresponds to the real one (RU Patent for Utility Model No. 169921, author Tigay Zh.G. et al., 2017). The disadvantage of this simulator is the complexity of the design and its use only in medical practice.

The objective of the proposed utility model is to create a simulator that allows improving the quality of training students in the technique of preparing male test subjects by simulating a real surgical situation, which makes it possible, after opening the common vaginal membrane at the bottom of the wound, to clearly see the white vas deferens against the background of the spermatic cord and excise a section of it.

The closest in its technical essence is a training complex for practicing bull castration skills. The training device is a full-color information panel with a scrotum phantom installed. The panel contains descriptions of castration, methods, indications and contraindications. Two methods of castration can be performed on the training device: surgical and percutaneous. The material used visually and palpably imitates the structure of the scrotum. However, the device has a significant drawback, which is that it is intended for castration, during which the function of the sex glands ceases, our invention allows you to preserve their action, since only a section of the vas deferens is excised.

The claimed simulator consists of a bag simulating the skin of the scrotum, inside which are placed two rubber chambers filled with filler, simulating the testicles and in them are two rubber tubes, simulating the spermatic cord and the vas deferens, the testicles are also placed in two rubber chambers simulating the muscular-elastic membrane, fascia and the general vaginal membrane.

The drawing shows a simulator for mastering the technique of preparing male test subjects in general. 1. Material simulating the skin of the scrotum; 2. Rubber chamber with filler simulating the testicle; 3. Rubber chamber simulating the membranes of the testicle; 4. Tube simulating the spermatic cord; 5. Tube simulating the vas deferens.

The simulator works as follows: The scrotum is treated with an antiseptic solution. Cuts 4-5 cm long are made on each testicle. The skin, muscular-elastic membrane, fascia and common vaginal membrane in the area of the caudal surface of the scrotal neck are successively dissected. After opening the common vaginal membrane, the vas deferens is clearly visible at the bottom of the wound against the background of the spermatic cord. The vas deferens is grasped with anatomical tweezers, and a piece of it 1-2 cm long is resected with scissors, and the stumps are released into the wound. The wound of the common vaginal membrane is sutured with a furrier's suture. A nodal suture is applied to the skin wound. The wound is treated with an antiseptic solution.
