Description

The utility model relates to surgical instruments, in particular, used to obtain anatomical preparations and can be used in anatomy and forensic medicine.

Known apparatus for liposuction "Body-Jet", which is an apparatus for removing subcutaneous fat by water-jet liposuction. The device consists of a built-in vacuum pump (aspirator), a geared motor with a control device, a built-in infiltration pump, a control unit, a power supply unit, a pressure gauge, a switching power supply, an operating meter, a set of foot switches, a cannula for water and suction, and a handle for cannulas and for connecting water supply and suction hoses, a suction bag. Irrigation fluid flows from the vessel through a system of tubes using a pump and leaves the system through the end of the instrument. The water flow rate is controlled from the control panel. The cannula is connected to the water supply and the aspirator with silicone hoses. The cannula is a metal tube with a length of 25 to 35 cm and a diameter of 3 to 5 mm. At the end of the cannula, there are three openings, one for supplying water, and two for removing subcutaneous fat.

This apparatus is inconvenient for the manufacture of anatomical preparations, as well as inconvenient to work in the conditions of sectional forensic bureaus and pathology departments, since it is impossible to connect it to the water supply, to carry out the procedure on anatomically narrow and limited parts of the body of the corpse, since the pointed cannula can damage the muscles and their fascia, as well as internal organs. [1] This device is taken by us as a prototype.

The purpose of the utility model is to create a device for hydropreparation of soft tissues and removal of subcutaneous fat.

This goal is achieved in that the body and the working part, in the form of a tube, 30 cm long and 15 mm in diameter, represent a single metal structure; the end of the tube is bent at an angle of 45 °, and the body has an ergonomic handle with a limiting arm; two through channels pass through the body and the working part, opening with holes at the end of the tube and in the brass threaded connections of the proximal part of the body, which serve to connect the twisted two-channel hose; the first channel serves to remove subcutaneous fat and is additionally communicated with the external environment through an opening in the housing having a rubber plug, the diameter of which is larger than the diameter of this hole; the second channel serves to supply water, which is limited by a ball valve having a handle with a rubberized corrugated plate; the distal end of the tube has the shape of a fish tail with smooth contours, in its upper part opens a channel opening to remove subcutaneous fat, and in the lower part a channel opening for water supply; also at the bottom of the end of the tube are two beds in which two LED cells with batteries are placed.

Smooth contours of the end of the tube reduce the likelihood of mechanical damage to tissues during their hydropreparation. The shape of the fish tail allows the flow of supplied water and the removed subcutaneous fat to be spread. Removable LED elements help to better navigate in the tissues, can be easily charged and replaced. The rubber plug on the case allows you to quickly and conveniently start and stop the removal of subcutaneous fat. The ball valve on the body allows you to conveniently control the pressure level of the water supply, and the handle of the crane with a rubberized corrugated plate will not allow your finger to slip off while adjusting the water supply. The twist of the two-channel hose prevents it from twisting. The device is reusable and convenient for sterilization.

A device for hydrotreating soft tissues and removing subcutaneous fat, containing a body, a working part, inside of which pass-through channels open through openings on the working part for supplying water and removing subcutaneous fat and on the proximal part of the body for connecting hoses, characterized in that the case and the working part, in the form of a tube, 30 cm long and 15 mm in diameter, represent a single metal structure; the end of the tube is bent at an angle of 45 °, and the body has an ergonomic handle with a limiting arm; two through channels pass through the body and the working part, opening with holes at the end of the tube and in the brass threaded connections of the proximal part of the body, which serve to connect the twisted two-channel hose; the first channel serves to remove subcutaneous fat and is additionally communicated with the external environment through an opening in the housing having a rubber plug, the diameter of which is larger than the diameter of this hole; the second channel serves to supply water, which is limited by a ball valve having a handle with a rubberized corrugated plate; the distal end of the tube has the shape of a fish tail with smooth contours, in its upper part opens a channel opening to remove subcutaneous fat, and in the lower part a channel opening for water supply; also at the bottom of the end of the tube are two beds in which two LED cells with batteries are placed.

The device is illustrated in graphic material. Figure 1A shows a diagram of a device for hydropreparation of soft tissues and removal of subcutaneous fat in the assembled state. Figure 1B shows a diagram of the distal end of the tube of the device.

The device for hydrotreating soft tissues and removing subcutaneous fat contains a working part in the form of a tube 1 and a housing 2, on which there is an ergonomic handle 3 with a limiting arm 4. Through the working part 1 and housing 2 pass: the first channel 5 for removal subcutaneous fat and a second channel 6 for supplying water. In the proximal part of the housing 2 there are brass threaded connections 7 into which openings of both channels open. Brass threaded connections 7 are used to connect a twisted two-channel hose 8. The end of the tube 1 has the shape of a fish tail with smooth contours, on the upper part of which there is an opening 9 of the first channel 5 to remove subcutaneous fat, and on the lower part - an opening 10 of the second channel 6 for water supply. Also on the lower part of the end of the tube 1 are two beds 11, in which two LED elements 12 with batteries are placed. The first channel 5 is in communication with the external environment through an opening 13 having a rubber plug 14, and the second channel 6 is blocked by a ball valve 15 with a handle 16 having a rubberized corrugated plate.

The device is used as follows. A two-channel twisted hose 8 is connected to brass threaded connections 7, one end of which is connected to a vacuum aspirator, and the other to a water mixer. The hole 13 remains open. On cadaveric material, a skin and subcutaneous tissue incision is made with a scalpel. The length of the cut should be greater than the diameter of the tube 1 of the working part of the device. Next, the tube 1 is introduced into the incision, pushing the subcutaneous fat. After that, the handle 16 of the ball valve 15 turn on the water supply and adjust its necessary pressure. Water flows from the water mixer into a two-channel hose 8, then passes through the second channel 6 and leaves the hole 10 at the end of the tube 1. In a dull way, under the influence of water pressure and pushing the working part, the subcutaneous fat is stratified, and then the plug 14 is inserted into the hole 13 A vacuum is created in the first channel 5, after which water is removed together with subcutaneous fat through the opening 9, along the first channel 5 into a two-channel hose 8 and into a vacuum aspirator. After achieving the desired result, the device is disassembled: the plug 14 is removed from the hole 13, the second channel 6 is closed with the handle 16 of the ball valve 15, the twisted two-channel hose 8 is disconnected from the brass threaded connections 7 and from the vacuum aspirator and water mixer. I process all parts of the device in disinfectant solutions.

The use of the device is illustrated by a clinical example. The corpse of a female G. 65 years old, the diagnosis of prolapse of the vagina and uterus. Our device was used for hydrotreating soft tissues and removing subcutaneous adipose tissue of the perineal region. During operation, optimal tissue preparation was performed. LED elements made it possible to better visualize tissue in the deep areas of the perineum. Damage to the anatomical structures during operation was not. Subcutaneous fat in the work area was completely removed. After hydropreparation with our device, we easily isolated the muscles and fascia of the perineum.

A device for hydrotreating soft tissues and removing subcutaneous fat can be used for forensic examination and the creation of anatomical preparations.
