Description

The technical field to which the utility model relates.

The utility model relates to medicine, namely to devices used in surgery.

The level of technology. During surgical operations, the surgeon often faces the need to dissect fascia, adhesions and aponeuroses, which are thin dense formations of multidirectional fibers of the connective tissue. In the presence of connective tissue dysplasia, these formations can be heterogeneous - with areas of low and high density. In some cases, it is necessary to dissect the connective tissue formation without further suturing. In patients with connective tissue dysplasia, re-fusion of a commissure or aponeurosis can lead to impaired organs, ischemia, and the development of necrosis. Currently, to prevent reunion, a significant portion of the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord) is excised, which is quite traumatic or repeated operations are performed.

The "Device for arthroscopic dissection of the anterior cruciate ligament in patients with connective tissue dysplasia" allows to solve the problem of reconnection of connective tissue structures [RF Patent for Utility Model No. 168636 of 02/13/2017]. This device is an arthroscopic forceps consisting of an outer casing, a handle and an internal movable mechanism, characterized in that the device is equipped with an additional crescent-shaped element having a cutting edge from the concave side, while the crescent-shaped element is movably attached to the working part of the outer casing in such a way that in the idle position, it is a continuation of the working part of the outer casing, and when you press the handle protrudes above it at least 45 ° from the main axis of the outer core pus, in addition to the cutting edge of the crescent-shaped element deposited crystals of artificial corundum.

The disadvantage of this device is that it can be used for arthroscopy and allows you to dissect only separately located thin formations (cords, ligaments, adhesions), but cannot be used when dissecting extended flat structures - aponeurosis, fascia.

As a prototype, a "scalpel-rasp containing a handle and a working part with surfaces forming at least one cutting edge, characterized in that protruding teeth are made in the form of quadrangular pyramids on one of the surfaces of the working part adjacent to the cutting edge while the cutting edge, combined with the edges of the base of the pyramids, is dulled "[RF Patent for utility model No. 79030 from 06/11/2008].

However, the use of this device during a surgical operation is associated with a number of disadvantages:

1. Prongs in the form of quadrangular pyramids cannot dissolve dense fibrous connective tissue formations, because it is necessary to have sharp cutting edges, they are more suitable for filing bone or cartilage structures.

2. There is no possibility of deep gradual razvolennosti cut the connective tissue structure.

3. The scalpel is difficult to manufacture.

4. The presence of furrows when creating quadrangular pyramids on a scalpel can make sterilization difficult.

Disclosure of utility model. The authors propose a scalpel for surgery for patients with connective tissue dysplasia, consisting of a blade (1) and a handle (5) connected motionless, characterized in that the side surfaces of the scalpel blade are covered with artificial corundum crystals, while the corundum crystals are located in the first third of the blade width, near the cutting surface, they have a size of not more than 0.5 mm (2), in the middle third of the width of the blade corundum crystals have a size of not more than 1.5 mm (3), the rest of the side surface of the blade animayut crystals ranging in size from 2.5 to 3 mm (4). In addition, the device can have a cutting surface with one-sided or double-sided sharpening, can be made of plastic, while its cutting surface must be made of steel, and its cutting surface can have a locking element, and can be replaced.

The device we offer has several advantages:

1. Artificial corundum crystals have multidirectional sharp edges

2. Due to the gradual increase in the size of corundum crystals in the direction from the cutting edge to the scalpel butt, razvolenenie cut the connective tissue object occurs gradually - first, small razvolenka (by 0.5 mm), then larger (by 1.5 mm) and then the most large - by 2.5-3 mm;

3. In the manufacture of the proposed device, the metal part of the scalpel or sheet metal is cut down, followed by sharpening and soldering corundum crystals - all these manipulations are easily performed and can be used in the conveyor production of scalpels;

4. The scalpel has a simple shape without deep furrows and cavities, which facilitates its sterilization in a hospital.

The technical result of using the proposed device is the simultaneous dissection and razvlechenie connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord) during surgery in patients with connective tissue dysplasia, to prevent re-fusion of the cut parts of the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord).

To characterize the utility model, in particular, the following features of the device are used:

- that the side surfaces of the scalpel blade are covered with crystals of artificial corundum;

- corundum crystals located in the first third of the width of the blade, near the cutting surface, have a size of not more than 0.5 mm;

- corundum crystals located in the middle third of the blade width have a size of not more than 1.5 mm;

- corundum crystals located on the rest of the side surface of the blade have a size of from 2.5 to 3 mm;

- the cutting surface of the scalpel can have one-sided or two-sided sharpening;

- the scalpel can be made of plastic, and its cutting surface can be made of steel;

- the cutting surface of the scalpel has a locking element and can be replaced.

Brief Description of the Drawings

In FIG. 1 shows a diagram (side view) of the proposed device:

- position 1 - scalpel blade;

- position 2 - artificial corundum crystals with a size of not more than 0.5 mm, located on the first third of the width of the blade, near the cutting surface;

- position 3 - crystals of artificial corundum with a size of not more than 1.5 mm, located on the middle third of the width of the blade;

- position 4 - artificial corundum crystals ranging in size from 2.5 to 3 mm;

- position 5 - the scalpel handle.

Utility Model Implementation

The claimed device can be applied as follows:

- the device is sterilized by the method adopted in this medical institution;

- in the operating room, a layer-by-layer incision of the skin and subcutaneous fat is performed to reach the area of the fibrous connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord);

- when dissecting the connective tissue structure (aponeurosis, fascia, ligament or connective tissue cord), the edges of the dissected object are simultaneously scratched by artificial corundum crystals located on the side surfaces of the blade;

- due to the gradual increase in the size of the crystals of artificial corundum from 0.5 to 3 mm, a gradual deep razvolenenie connective tissue formation, which prevents the re-fusion of the edges.
