Abstract

To reduce the installation time, the clamp consists of the upper branch (B) 1 and the lower B 2, connected by elastic plates 3. On B 1, clamping elements 4 are installed with the possibility of movement in a vertical plane. The plates 3 are fixed on the ends B 2 with the help of hinges 5, and the fixing of their free ends in the guide grooves B 1 is carried out with screws 7 with figured couplings. The clamping elements 4 are mounted on a cross-shaped equal shoulders (RP). The upper ends of the RP are fastened in shaped grooves with B 1 on the axles with a flat face and handle. The lower end of each RP is provided with an axis for fixing it in the groove of the working element. There is a flat spring on the axis that is crosswise connecting RP. 3 il. (L 00 00 th Phi.1

Description

The invention relates to surgery, namely, clamps for operations on the liver.

The purpose of the invention is to reduce the installation time of the clamp.

FIG. 1 shows a clamp for operations on the liver, a general view; in fig. 2 is a diagram of the clamping element; in fig. 3 is a diagram of fixing a flexible rack in the upper branch.

The clamp consists of the upper 1 and lower 2 branches, interconnected by a mechanism in the form of elastic plates 3. At the upper branch, clamping elements 4 are mounted, which move in a vertical plane. The elastic plates 3 are fixed at the ends of the lower branch with the help of hinges 5, and arbitrary fixing of their free ends in the guide grooves 6 of the upper branch is carried out with screws 7 with figured couplings 8. The clamping elements 4 are mounted on cross-shaped equal sized shoulders 9. Upper ends equal shoulders are fixed in figure grooves 10 from the upper branch 1 on the axes I and with a flat 12 and handle 13. The lower end of each equal shoulder is provided with an axis 14 for fixing it in the groove 15 of the working element. On the axis 16, which is crosswise connecting the equal shoulders, there is a flat spring 17.

The clamp works as follows.

After laparotomy and revision of the cavity, the removed part of the liver is mobilized and a clamp is placed on it, the upper branch 1 is inserted into the subdiaphragmatic (suprahepatic) space, and the lower branch 2 is placed under the visceral surface of the liver. Then, depending on the thickness of the part of the liver to be removed, the upper and lower branches are brought together as close as possible by the fingers, which is easily accomplished by sliding the free ends of the elastic plates 3 in the guide slots 6 of the upper branch and fix the elastic plates with screws 7, aiming for so that the distance between the arms 1 and 2 of the clip is the same over the entire length.

After that, the handles 13 are turned in such a way that the axes 11 are with the lip 12 down (the handle stands vertically) and, displacing the handles 13 towards each other in the figured grooves 10 of the upper arm 1, moves the clamping elements 4 into

vertical plane (one or in the required combination), and then turning the handle 13 to a horizontal position (the axes are turned with a side 12 to the side) arbitrarily fix each equal shoulder 9 of the clamping element 4, as a result of which

0, temporary hemostasis is achieved at any part of the liver along the clamping line.

At the same time, as a result of arbitrary displacement of the clamping elements 4, the degree of compression of the liver can be changed to achieve bleeding in the removed part of the liver without damaging its parenchy we.

The next step is to remove the depot area of the liver and process the stump by known methods.

Then, turning the handle 13 vertically (the axis. 11 is turned with the lip 12, down) releases the equal shoulders of the clamping elements 4 and they, consumed by the action of the flat spring 17, return the clamping elements to their original position.

After that, the free ends of the flexible struts are released, the jaws of the clamp are separated and removed from the quarry cavity.

After the usual peritonealization of the wound i: e-, the checks are made layer-by-layer by the infusion of the bruine cavity.
