UA8069U - Method for applying end-to-side vascular anastomosis using vascular spatula - Google Patents

Abstract

The method for applying end-to-side vascular anastomosis using the vascular spatula comprises the fixation of the prosthesis "heel" to the corners of the arteriotomy wound and the pressure applied to the anterior wall of the anastomosis with the aid of the vascular spatula. Finally, uninterrupted suture is applied.

Description

Description of the invention

The utility model relates to medical equipment, namely to instruments used in vascular 2 surgery.

There is a method in which the so-called "heel" prosthesis is fixed to the corner of the arteriotomy wound, and its free edge, with constant tightening with tweezers, is sewn with a continuous seam around the perimeter of the artery wound (11.

Due to frequent grasping with tweezers, the edge of the synthetic prosthesis becomes frayed, which can affect the strength of the anastomosis, and the villi of the frayed prosthesis getting into the lumen of the vessel can cause the danger of thrombosis in this area. In addition, the retracted opposite edge of the prosthesis can be accidentally caught in the suture.

As a prototype, the method of applying end-to-side vascular anastomosis, in which both the "heel" of the prosthesis and its free end are simultaneously fixed to the corners of the arteriotomy wound |2). But at the same time, with each stitch of a continuous seam, the edge of the prosthesis is pulled up with tweezers, which unravels it, and the opposite edge of the prosthesis is turned into the lumen of the vessel. 12 The useful model is based on the task of improving the technique of applying end-to-side vascular anastomosis and preventing the possibility of the above-mentioned complications.

This is achieved by the fact that after fixing the Z-shaped cut end of the prosthesis in the "heel" area and its free end 2 to the corners of the arteriotomy wound (Fig. 2), the front wall of the formed anastomosis Z is pressed into the lumen of the artery with a special vascular spatula (Fig. 1), consisting of a handle 4 and a rod 5, which ends with a flat plate 6 with rounded corners, 20 mm wide and 7 mm high.

The edge of the prosthesis is aligned with the edge of the semicircle of the arteriotomy wound and remains immobile when applying a continuous suture. With tweezers, the edge of the prosthesis is slightly compressed to the edge of the wound of the artery at the time of puncture with an atraumatic needle, which protects the prosthesis from defibrillation.

The blade, pressing the front wall of the anastomosis into the lumen of the vessel, divides it into two channels 7 and 8, which prevents the opposite edge of the prosthesis from collapsing into the lumen of the vessel (Fig. 3). in

Claims (1)

The formula of the invention is the method of applying end-side vascular anastomosis using a vascular blade, which includes 75 simultaneous fixation of the "heel" of the prosthesis and its free end to the corners of the arteriotomy wound, which differs in that after fixing the prosthesis to the corners of the arteriotomy wound, the front wall of the anastomosis is pressed a vascular spatula into the lumen of the artery, and a continuous suture is applied along the outer and inner semicircles of the formed anastomosis to the converged and juxtaposed edges of the prosthesis and the wound of the vessel.
