Description

Vessel Dissector Clamp

The utility model relates to surgery and can be used during operations on vessels of the retroperitoneal space to isolate and fix the vessel wall before flashing or dressing.

Known clamp-dissistor, included in the "Set of surgical instruments for operating from small incisions (Patent No. 45120 for industrial design, publ. 1998). The known clamp is a jaw that is bent in a horizontal plane at an obtuse angle, pivotally connected, having a working part in the form of jaws and a handle ending in rings. In this case, the end of the working part is annularly curved to the plane of movement of the branch and is provided with a notch.

The known clamp is intended for manipulation with vessels of relatively small diameter, such as, for example, the gallbladder cystic artery and others located mainly in the abdominal cavity. Therefore, the working end of the clamp is made narrow, almost sharp.

Retroperitoneal vessels, such as in the ligaments of the adrenal gland, adrenal vein, and vessels of the kidneys, are distinguished by a large diameter, and a thinner, easily vulnerable wall.

When isolating and fixing such vessels using a known clamp, there is the possibility of damage to the wall with a sharp working end, which entails the need for repeated stopping of bleeding. It increases blood loss.

creates additional trauma to the patient and inconvenience to the surgeon.

In addition, when testing a well-known clamp for such vessels, it turned out that the length of the working jaws and the height of the curved end of the working jaws from the plane of movement of the branches are insufficient for reliable fixation and retention of the vessel wall and also create inconvenience to the surgeon's work, limiting its capabilities.

The objective of this technical solution is to create a clamp-dissector, which allows without trauma to reliably fix and hold vessels with a large diameter and a thin wall in a deeper surgical wound.

To solve this problem, the clamp-dissector for blood vessels contains curved in a horizontal plane at an obtuse angle, articulated to the annular handles at one end of the jaw and working jaws on the other, while the end of the working jaws is annularly curved in the direction perpendicular to the plane of movement of the jaw and equipped atraumatic notch, the length of the working jaws from the hinge is 180 mm., and the height of the curved end of the working jaws from the plane of movement of the jaw is 25-35 mm., while the ends of the working jaws at cm Punches form a rounded thickening at the end.

A new technical result consists in the “non-invasiveness of introducing the working end of the dissector under the vessel when it is filled out due to the presence of a rounded thickening on it, and the possibility of using a more gentle working end notch for reliable but soft hold of the fixed clamp on the vessel.

A new technical result allows you to create less traumatic conditions for reliable dressing or flashing of a thin-walled vessel.

Figure 1 shows the clamp-dissector for vessels, a general view, in Figure 2 is the same, view A is on the working end, in figure 3 is view B on the notch of the working end. The clamp contains jaws 1 with working jaws 2, the length of which LI from the hinge 3 is 180 mm, and the height of the curved end of 4 working jaws from the mixing plane, the jaw L2 is 25-35 mm. When closed, the ends of the working jaws form a rounded thickening 6. The length of the atraumatic notch L3 is 45–55 mm.

The clamp was used in adrenal gland removal surgery. After dissection of the posterior sheet of the peritoneum, a platform of the inferior vena cava was isolated on the right (renal vein, on the left) above and above the inflow of the adrenal vein.

Then, with the movement of branch 1, a tunnel was created behind the central vein of the adrenal gland, and then in the paved tunnel one of the branches was opened under the vein and with help; a vessel was fixed by closing both branches. Then he was crossed and ligated or stitched under a clamp-dissector.

Claims (1)
