Description

The technical field to which the utility model relates.

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

State of the art

There are arterial, venous, mixed, capillary and parenchymal bleeding. Bleeding is external (with blood flowing out), internal (with blood flowing into tissues, organs, cavities) and mixed (external and internal). Stopping bleeding can be temporary and final. The most difficult is the elimination of bleeding from the parenchymal organs, due to the large area of bleeding (bleeding over the entire surface) and the cutting of the needle and suture material.

The liver is a parenchymal organ. With her traumatic injury, it becomes necessary to temporarily stop her blood supply in order to search for a damaged lobe or segment, remove it, suture, or conduct electrocoagulation. The preparation of the hepatoduodenal ligament with the release of vascular elements requires considerable time and can lead to trauma to the common bile duct.

One of the ways to temporarily stop the blood supply to the liver is by finger clamping of the hepatoduodenal ligament of sludge and the use of an elastic clamp such as the Hepfner clamp (prototype).

Hepfner (Hepfner) clamp - was proposed at the beginning of the 20th century by the German surgeon E. Hopfner as a hemostatic clamp for temporarily stopping bleeding during operations related to manipulations on blood vessels. It is a straight or slightly curved clamp with wide elastic lips having longitudinal grooves on the working surface that prevent the tool from slipping even with slight tissue compression [http.Y / operhirvgmu.narod.ru / museum / krovoost / spisok.htm and http: / /znaiu.ru/art/403 700400.php]. Hepfner’s clamp is made of tool steel and cannot be bent during an operation without breaking it.

Hepfner's clip is depicted in figure 1.

However, the above device has several disadvantages:

1. The clamp is straight and short, making it difficult to use deep in the wound.

2. The full capture of the duodenal pedicle requires wide surgical access or additional lateral access.

Utility Model Disclosure

The authors propose modifying the Hepfner clamp and using it to clamp the elements of the hepato-duodenal ligament.

The device we offer has several advantages:

1. the long handle allows for manipulation in the depths of the wound;

2. The perpendicular position of the plane of the working part relative to the plane of the connection makes it easy to bring the clamp to the hepatoduodenal ligament;

3. the angle between the working part and the handle allows you to easily bring the clamp to the hepatopoduodenal ligament;

4. the manufacture of the working part of the elastic material allows you to squeeze the vessels passing in the hepatoduodenal ligament without trauma.

The technical result of using the proposed device is to obtain the possibility of a temporary stop of bleeding during manipulations on the liver, without traumatizing the surrounding tissues, rupture of the parenchyma and damage to the elements of the hepato-duodenal ligament in a deep surgical wound.

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

- the plane of contact of the working parts of the clamp is perpendicular to the plane of the movable connection,

- the angle between the working part and the handle is at least 80 °,

- the working part has a thickness of at least 0.5 mm and a width of at least 3 mm

- the working part is made of elastic material,

- the length of the handle is at least 150 mm,

- on both working parts there are recesses located on surfaces facing each other, parallel to the long edge of the working part and having a depth of not less than 0.1 mm. Brief Description of the Drawings Figure 1 shows a photograph of a Gepfner clamp. Figure 2 shows the clip we have proposed for clamping the elements of the hepato-duodenal ligament:

- position 1 - working part;

- position 2 - hinge;

- position 3 - handle;

- position 4 - the angle between the handle and the working part;

Utility Model Implementation

- The device undergoes sterilization according to the scheme adopted in this hospital.

- During the operation, the clamp is inserted into the surgical wound and the pre-allocated hepatoduodenal ligament is pinched.

- After a temporary stop of bleeding, manipulations are made on the lobe of the liver.

Not later than after 15 minutes, the clamp is removed, and the blood supply to the organ is restored.
