Abstract

A surgical simulator for applying intestinal sutures and anastomoses, containing a base and fixation devices located on it, characterized in that the base is made in the form of a tablet table on which two soft intestinal clamps are located, one of which is fixed motionless and the other is movable on rails, between which there are several clamps-holders on the sides of the table-tablet, and on the side of the movable intestinal clamp, a cylinder for putting on the intestine is located perpendicular to it, which is connected to the mano meter through a tube with an air blower located on it.

Description

SURGICAL SIMULATOR FOR INTESTINAL AND ANASTOMOSIS

The utility model relates to medicine and can be used to train and improve surgical techniques for intestinal sutures and anastomoses.

Known surgical simulator Yu.T. Komorovsky and V.I. Pyatnochki, consisting of a base and a hollow organ simulator mounted on a support plate in the form of two three-layer tubes. Each layer of tubes is painted in a different color. The rewind mechanism is made in the form of two rollers with their fastening elements to the base, protruding guide rings are rigidly mounted on each roller. Position adjusters allow you to rotate the rollers and move the tubes, (A.S. No. 1504bbO; Publ. Eyul.Yu from 30.08.89.

The simulator of E.T. Komorovsky and V.I. Pyatnochki excludes the possibility of focusing on the correct anatomical structure of the intestinal wall, since the simulator is made of a three-layer tube, which cannot be considered an analogue of the intestine, the wall of which, in reality, consists of four spruces. it does not allow to take into account the features of the thickness, density and mobility of all layers of the intestinal wall in various parts of the gastrointestinal tract and to assess the degree of trauma to the intestinal wall with surgical instruments during the application Whether or other type of suture anastomosis, as testing of operating appliances is carried out on cloth tubes made of tkani.TrenaMKI5 June 9 in 23 /; a8

GER does not allow to give an objective assessment of the quality of stitches and anastomoses and to monitor the quality of the techniques of mastered surgical techniques.

The utility model is aimed at solving the problem of improving the development of surgical techniques for the application of intestinal sutures and anastomoses by using the intestinal preparation.

This task is achieved using the base in the form of a tablet-table, on which there are two soft intestinal clamps, one of which is fixed with the ability to move along rails. Several pairs of clamps-holders are located between the niches on the sides of the tablet. On the side of the movable soft intestinal clamp is perpendicular him, there is a cylinder for putting on the intestine, which is hermetically connected to the manometer by means of a tube with an air blower located on it.

The device is shown in the drawing, where Fig. 1 is a top view, and in Fig. "Is a front view. The simulator consists of a base, which is a rectangular-shaped table-tablet 1, on which two soft intestinal clamps 2 and 2 are located parallel to each other , the distance between which, if necessary, can be easily changed by moving one of the clamps along the rails 3, fixing it with a fixing screw 4. On the sides ti, three pairs are located between the soft flare clamps i, opposite each other

clamps-holders, such as a crocodile. On the side of the movable intestinal clamp perpendicular to it is a cylinder for putting on the gut b, on the free edge of which there is a gut retainer 7. The opposite edge of the cylinder b is hermetically connected by means of a connecting tube 8 to the air blower 9 and the pressure gauge 10. Intestinal clamps (and, cylinder b, pressure gauge 10 and clamps-holders 5 are located on the table-plate I on tripods of the same height.

The device is used as follows: the plate I is placed on the table with cremoliers of soft intestinal clamps and to itself. One or more segments of the intestinal preparation (depending on the type of suture or anastomosis applied) are fixed between the soft intestinal clamps d and "da and on the clamps-holders 5 in a convenient position relative to each other, by adjusting the distance between the clamps and using the rails 3 and the fixing screw 4. Surgical techniques are performed using conventional surgical instruments. To assess the quality of false or anastomosis seam, provided the integrity of the remaining segments of bowel preparation pnevmopressiyu produce. One end of the intestine is put on the cylinder b and hermetically fixed with the fixative of the intestine 7. The other is fixed in a movable intestinal clamp and tightly tied to the inside with a thick thread. After that, the intestine under investigation is inflated with air using an air blower 9 and looking on the manometer 10, note the level of pressure that caused the depressurization in the intestine, by which they judge the severity of the stitches or anastomosis.

Positive effect: the simulator allows you to impose any type of intestinal sutures and anastomoses, taking into account the anatomical features of the structure of the intestinal wall of various sections of the gastrointestinal tract, reuse intestinal preparations with a length of 5 cm or more, work out techniques without the help of an assistant, or working alone three operators at the same time, give an objective assessment of various types of intestinal sutures and compare the physical integrity of the anastomoses imposed by various methods and suture materials, l quality control of the techniques of mastered surgical techniques using pneumatic compression, to evaluate the manipulative properties of various suture materials. The advantages of the proposed device is the ability to use it in any training rooms, both for the development and improvement and for demonstrating the surgical techniques necessary for performing surgical interventions on hollow organs of the gastrointestinal tract.
