The operation time is reduced.

Description

The invention relates to medical equipment, in particular to medical instruments for clamping blood vessels located in the area of the gate of organs and simultaneously applying ligatures to them and administering various drugs by puncture.

Known devices for clamping and ligation of vessels during operations on organs - this is the use of a conventional clamp, mosquito, Deschan’s needle and a special device for clamping vessels (AS No. 1500273) and others do not always satisfy practical surgeons, since they are traumatic, large sizes, it becomes necessary to select several tools, not reliable.

As a prototype, we selected the device of M.A. Moroz for clamping blood vessels and applying ligatures (a.s. No. 1500273), consisting of two articulated intersecting branches with finger rings and a cremallera. The branches are bent along the radius in the plane of the finger rings and have notches on the contacting surface; on the working ends of the branches there are coaxial holes in which removable tips with ligature holes are fixed with a shank.

It has the following disadvantages: trauma, large size and inconvenience to manipulate inside the cavities. Moreover, each time it is necessary to refill the tips with holes with a ligature and remove them when the vessel is ligated, it does not allow to simultaneously press the vessel, apply a ligature and puncture it.

The purpose of the proposed as a useful model of the device is to improve the device for clamping, applying ligatures and the introduction of drugs into blood vessels.

Utility Model Description

The proposed utility model is illustrated in Fig. 1, pos. A, b, c, d, where pos. A, d - 1 - handle, pos. A - 2 - swivel; pos.a - 4 - working jaws, pos.b - upper jaw; pos.v - lower jaw; pos.a - 3 - elastic spring, pos.a, g - 5 - handles (Figure 1).

The device consists (Fig. 1, pos. A, b, c, d) of two removable plate jaws - nozzles (Fig. 1, pos. B, c), a handle (Fig. 1, pos. A, d - 1) and working jaws (pos. a - 4), a lock of the "clothespin" type - a spring (pos. a - 2, 3). Each branch is conditionally divided into three parts (front, middle, end).

The branches are made in the form of plates with dimensions of 2 cm long and 1.2 cm wide each (Fig. 1, pos. B, c.).

The upper branch (pos. B) has a groove in the front part (window) in the center measuring 0.5 cm wide and 0.8 cm long (pos. B - 1), in the middle part there is a zone for clamping the vessel with a length of 0, 3 cm and a width of 1.2 cm (pos. B - 3), in the end part there is a through groove (pos. B - 2) for ligature with a width of 0.8 cm and a length of 0.5 cm.

The lower jaw (pos. C) has a semicircular recess (pos. 1) in front of the window (top jaw) in accordance with the curvature of the vessel and the size of the window of the upper jaw, in the middle part there is a zone for pressing the vessel with a length of 0.3 cm and a width 1.2 cm, corresponding to the dimensions of the middle part of the upper jaw (pos. 3), in the end part of the jaw there is a through groove (pos. 2) in accordance with the dimensions of the through groove of the upper jaw. Open it by pressing on the handles (5) and releasing, the device closes, i.e. the branches are pressed (Fig. 1, pos. a).

Given the diameters of the vessels at the gates of the organs, it is possible to manufacture (pick up) sets of branches with the necessary diameters of the vessels.

An example of a practical application of the device:

Mongrel dog, male, 2.5 years old, weight 17 kg. The bug

Upper median laparotomy, spleen was isolated into the surgical wound.

The vascular leg of the organ was mobilized. Superimposed this device on the zonal vascular pedicle. First, in the front part, where the window was punctured by the splenic lobar artery and the solution was injected into the corresponding area of the organ. Then this zonal vessel was ligated, passing the ligature through the through groove in the end of the branches. Remove the device and performed zonal resection of the spleen. Reliable hemostasis and layered seams.

Example. Dog "Golden Eagle" - female, 3 years old, weight - 19 kg.

The abdominal cavity was opened with a mid-median incision along the white line of the abdomen.

The liver was isolated. Mobilized the gate of the liver. Then put the device on

lobar hepatic artery. In front of the pressure zone in the front part, where the window was punctured by the hepatic lobar artery and the solution was injected into the corresponding organ lobe. Some time after staining the lobes, the corresponding lobar hepatic artery was ligated, ligating through a through groove in the end of the device. Remove the device and resect the corresponding portion of the organ. Hemostasis and layered sutures on the wound.

This device was used for lobar resections of the spleen and liver in 20 cases with good results.

Features distinctive from the prototype

1. In the proposed utility model there are lamellar branches - nozzles, and in the prototype - intersecting branches with notches, which cause unnecessary trauma to the vessel wall and intima.

2. In the proposed utility model, the jaws are removable from the handles, and in the prototype - connected and only the tips with holes are removable to fix the ends of the ligatures, which does not allow you to pick up the jaw of the corresponding diameter vessel.

3. In the proposed model in the upper branch there are: a) a window for puncture, b) a through groove in the end part for ligature during ligation of the vessel, which is convenient to use, as it allows you to simultaneously press the vessel, without removing it, if necessary, ligature and puncture (cannulate), and in the prototype are absent.

4. In the proposed utility model in the front of the lower jaw there is a semicircular recess, which is convenient: the vessel does not move during puncture and excludes puncture of its posterior wall, and this sign is absent in the prototype.

5. In the proposed utility model, the lock in the form of a “clothespin” is a spring, which allows you to open and close it with a light push, which provides technical simplicity, convenient to use, low traumatism, and in the prototype a creme lock.

6. In the proposed utility model, the dimensions (length) of the device are 2 times smaller than in the prototype, which makes it easy to manipulate inside the cavities. A positive effect from the use of the proposed device is to facilitate the work of the surgeon during operations on internal organs, namely, it allows you to simultaneously squeeze the vessel, apply a ligature, passing it through the through groove in the end of the jaw, simplifies the technique of puncture of the vessel, since the vessel does not

displaced during the puncture, which eliminates the puncture of its posterior wall, since it is protected by a jaw plate. The operation time is reduced. The proposed device can find practical application in the surgery of parenchymal organs, blood vessels and other surgical interventions in the area of the gates of organs.
