Problems solved by technology

This method requires two-handed operation, and the circular motion is converted into linear motion through the rotating operation. Not only is the laborious process easy to cause fatigue to the doctor, but also the anastomotic ring is fitted with little force, which makes it difficult to ensure the fit of the anastomotic blood vessels, which in turn affects the vascular anastomosis Effect
At the same time, when the force is exerted by both hands, the strength is relatively large, and it is easy to shake, which greatly reduces the stability during the surgical anastomosis process and easily causes anastomosis failure.

Embodiment 1

[0063] A hand-held trigger kiss ring nick-in-cell blood vessel device, such as figure 1 As shown, including the handle assembly 1 and the execution assembly 3 connected by the connection assembly 2, the handle assembly 1 includes a fixed handle 101 and a trigger handle 102 hinged to the fixed handle 101, the trigger handle 102 is connected to the drill 103, and the dial member 103 is Patch;

[0064] Specifically figure 1 , 2 As shown, the connection assembly 2 includes a fixed lever cover 201 and a moving rod 202, a fixed rod jacket 201 connected to the fixed handle 101, and the movable rod 202 can relatively straightforwardly in the fixed rod jacket 201, and the movable rod 202 is connected to the drill 103, activity The other end of the rod 202 is connected to the two toguibing the lam 203, and the two ends of the two adhesive plates 203 are close to each other and the other end is away from each other;

[0065] Specifically figure 2 As shown, the execution assembly 3 includes a...

Embodiment 2

[0068] A hand-held trigger kiss ring nick-in-cell blood vessel device, such as image 3 As shown, the difference from the first embodiment is that the dial 103 is a dial, and the patch is connected to the movable rod 202 through the first recess 104, and the first recess 104 is used to increase the plug 103 and the movable rod 202. The connection area, the reinforcing connection, and the trigger handle 102 moves forward and rear motion through the first recess 104 through the first recess 104. The remaining settings were the same as in Example 1.

Embodiment 3

[0070] A hand-held trigger kiss ring nick-in-cell blood vessel device, such as Figure 4 As shown, the difference from the first embodiment is that the movable rod 202 is set to two, and the two ends of the two condensation plates 203 are each inserted, and it is used to make the anastomotic plate 203 is uniform and stable. The plate 203 is inserted with the movable rod 202 by the first position pin 216, and the two end faces of the engagement end of the lam 203, and the faces corresponding to the socket are respectively copied. The remaining settings were the same as in Example 1.

Abstract

The invention discloses a device and a method for vascular anastomosis by holding trigger anastomosis rings. A handle assembly comprises a trigger handle hinged to a fixed handle, and a stirring piece is fixed to the trigger handle; the stirring piece is connected with a movable rod, the movable rod is connected with two anastomosis promoting inclined plates, one ends of the two anastomosis promoting inclined plates are close to each other, the other ends of the two anastomosis promoting inclined plates are away from each other, and the movable rod can do reciprocating linear motion relative to a fixed rod sleeve; and an execution assembly comprises the anastomosis rings connected to fixed blocks respectively, the fixed blocks and a torsional spring sleeve a mounting shaft, the two ends of the torsional spring abut against the fixed blocks respectively, and the mounting shaft is connected to the fixed rod sleeve. The trigger handle rotates around the fixed handle to drive the stirring piece to move, the stirring piece drives the movable rod to do linear motion, the movable rod drives the anastomosis promoting inclined plates to extend forwards, and the anastomosis promoting inclined plates overcome the elastic force of the torsional spring to make the pair of anastomosis rings fit. The device can be operated with one hand, and is simple and labor-saving, the fitting stress of the anastomosis rings is large, the fitting degree of anastomotic vessels is ensured, and the vascular anastomosis effect is ensured.

Description

Technical field [0001] The present invention relates to the technical field of medical appliances, and more particularly to a hand-held trigger anonymous ring namstretic aircraft and method. Background technique [0002] Vascular anastomosis is a surgical technique that connects two vaschers into a surgical technique, such as in various surgical surgery, such as plastic surgery, hepatobiliary surgery, cardiothoracic surgery, urology, obstetrics and gynecology, etc. In the middle, the blood vessel anastomosis is needed. Vascular anastomosis is one of the most important steps in the above-mentioned surgery, and its success or failure is directly related to the surgery to survive after surgery. [0003] The blood vessel anastomosis in the current clinically includes a suture anastomosis and a mechanical staple aigenic, wherein the fracture of the blood vessel is consistent with the sewing of the broken end of the blood vessel. It is the currently recognized blood vessel anastomotic ...
