Embodiment Construction

[0021] Refer below Figure 2 to Figure 7 The specific implementation of the side-to-side anastomosis fixture of the present invention will be described in detail.

[0022] figure 2 It is a schematic structural view of the side-to-side anastomosis fixture, which is the first embodiment. Such as figure 2 As shown, the side-to-side anastomosis fixator 2 includes a sleeve 4, and a connecting rod 3 is sleeved in the sleeve 4. end sticks out. A disc-shaped control handle 31 is integrally formed on the top of the connecting rod 3 , and the control handle 31 is integrally located outside the casing 4 . A first clamping portion 51 is provided on the outside of the bottom of the sleeve 4, and a second clamping portion 52 is provided on the outside of the bottom of the connecting rod 3, as figure 2 As shown, the first clamping part 51 and the second clamping part 52 are both in the shape of "]" arranged horizontally, the planes of the first clamping part 51 and the second clampin...

Abstract

The invention brings forward a side-side anastomosis fixing device. The side-side anastomosis fixing device comprises a sleeve, a connecting rod which is sleeved in the sleeve and has a bottom end extending out of the bottom of the sleeve, a control handle configured at the top of the connecting rod, the outer side of the bottom of the sleeve is provided with a first clamping portion, the outer side of the bottom of the connecting rod is provided with a second clamping portion, the first clamping portion and the second clamping portion form a vein clamp for fixing an autologous vein, and through controlling the control handle, the connecting rod is enabled to carry out axial reciprocating movement relative to the sleeve and the second clamping portion is enabled to perform reciprocating movement relative to the first clamping portion to form opening and closing states of the vein clamp. The side-side anastomosis fixing device is simple in structure, easy to operate and convenient to use. During an operation, an assistant can operate the side-side anastomosis fixing device by use of only one hand so as to fix the autologous vein, the other hand of the assistant is liberated, and the assistance capability of the assistant in the operation is enhanced.

Description

technical field [0001] The invention relates to a side-to-side anastomosis fixer. Background technique [0002] Coronary heart disease is a common heart disease at present, and bypass surgery is an effective means to treat coronary heart disease. In bypass surgery, end-to-side anastomosis and side-to-side anastomosis are the two most commonly used anastomosis methods. The autologous vein is the most commonly used grafting vessel, which is characterized by its own lack of support, such as figure 1 As shown, when performing side-to-side anastomosis, the assistant should separate the two tweezers 8 by a certain distance, clamp the body of the vein 7 at the same time, and straighten the vein 7 to fix the body of the autogenous vein 7 . Adopting this anastomotic method takes up both hands of the assistant, weakening the ability of the assistant to assist the operation. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide...
