Endoscope double-row type blood vessel stitching instrument for thoracic surgery

Abstract

The invention discloses an endoscope double-row type blood vessel stitching instrument for thoracic surgery, which comprises a main handle, a cavity tube, a fixing shaft I, an auxiliary handle, a channel I, a push rod, a fixing shaft II, a pressing plate, a channel II, a sliding rod, a U-shaped clamping plate, a fixing plate and an avoiding hole. According to the invention, firstly, through the separation design of the vascular stenosis gap, separated blood vessel suture is conveniently carried out in the vascular stenosis gap area. the surgical operation convenience is improved, and the problems that a traditional closing instrument is large in width, inconvenient to operate and prone to causing blood vessel injury and bleeding are effectively solved; secondly, through the matching effect of the hook bin mechanism, preoperative filling is facilitated, the intraoperative operation time is shortened, in addition, the effects of rapidly suturing blood vessels and improving the operation convenience and stability of medical staff can be achieved; and a bleeding blood vessel is directly pressed for suturing after being clamped by the endoscope forceps type blood vessel suturing instrument, and the bleeding blood vessel does not need to be separated before suturing, so that the safety and the convenience of surgical operation are improved, and the practicability of a clinical operation is expanded.

Description

Technical field[0001]The present invention relates to a vascular suture, and more particularly to a thoracic surgery cavity double-row vessel suture.Background technique[0002]Current clinical laboscopic surgery, the closing and hemostasis of 5 mm or more, has been plaguing the technical difficulties of clinicians, and therefore, some instruments that can directly close and hemoststleblow for large blood vessels, such as traditional cavoscope Vascular cutting suture, HEM-O-LOCK, etc., existing equipment, etc., existing equipment, etc., is currently designed for six-row design, hook due to traditional cavoscope blood vessel cutting suture The width and area of ​​the warehouse are large. The medical personnel must separate the vascular and surrounding tissue before closing the blood vessels, in order to achieve effective insertion of the instrument, and cut the blood vessels. Since it is necessary to have a large enough space, not only the difficulty is greatly improved, but in the ins...

AI Technical Summary

Problems solved by technology

Due to the need to free a large enough space, not only the difficulty of the operation is greatly increased, but also during the insertion of the separated tissue and the instrument, it is easy to cause blood vessel rupture and massive bleeding, and prolong the operation time, which ultimately brings great safety to the clinical operation. Hidden danger

2. Although it is convenient to use hem-o-lock clinically to clamp blood vessels, the volume of hem-o-lock is large. In some operations with small space and tight tissue gaps (such as the operation on the hilum), it is difficult for subsequent operations. The operation brings a lot of interference. In addition, clinically, blood vessel injury and rebleeding often occur at the hem-o-lock clipping site, and hem-o-lock slippage and collapse often occur.
