Embodiment 1

[0040] An embodiment of the present invention provides a blood vessel stapler, which includes: a first stapling plate 1, a second stapling plate 2 and a control handle 3, the shapes of the first stapling plate 1 and the second stapling plate 2 are Ring, the curvature of the inner ring of the first stapling plate 1 and the second stapling plate 2 is adapted to the curvature of the outer wall of the large blood vessel; the first stapling plate 1 is connected to the first output end of the control handle 3, The second anastomotic plate 2 is connected to the second output end of the control handle 3 , and the control handle 3 controls the closing and opening of the first anastomotic plate 1 and the second anastomotic plate 2 .

[0041] In the above structure, through the closure between the first anastomotic plate and the second anastomotic plate, it can be used for anastomosis between blood vessels. The closure of the blood vessel is pressed together to realize the anastomotic re...

Embodiment 2

[0047] On the basis of Embodiment 1, the first anastomotic plate 1 of this embodiment includes: a first clamping piece 6 and a second clamping piece 7, and the first clamping piece 6 and the second clamping piece The pieces 7 are all semicircular arc structures, one end of the first clamping piece 6 and one end of the second clamping piece 7 are hinged through a first pin 8, and the first pin 8 is connected to the control handle 3 The other end of the first clamping piece 6 is provided with a first buckle 9, the first buckle 9 is a U-shaped structure, and the two ends of the first buckle 9 are respectively hinged On the first clamping piece 6 , the other end of the second clamping piece 7 is provided with a first tongue 10 , and the first tongue 10 is protruding from the second clamping piece 7 . Cylindrical structure, the first tongue is adapted to the first buckle 9; the second anastomotic plate 2 includes: a third clamping piece and a fourth clamping piece, the third clampi...

Embodiment 3

[0050] On the basis of Embodiment 1, the control handle 3 of this embodiment includes: a first control rod 11 and a second control rod 12, one end of the first control rod 11 is connected to the outer surface of the first anastomotic plate 1 Convex connection, one end of the second control rod 12 is connected to the outer convex surface of the second anastomotic plate 2, the middle part of the first control rod 11 and the middle part of the second control rod 12 are intersected, and the The middle part of the first control rod 11 and the middle part of the second control rod 12 are hinged to each other.

[0051] Further, it also includes: a pair of first arc-shaped rods, a pair of said first arc-shaped rods are respectively arranged on the first control rod 11 and the second control rod 12, one end of the first arc-shaped rod is connected with the first control rod The rod 11 or the second control rod 12 is connected, and the other end of the first arc-shaped rod is far away f...

Abstract

The present invention provides a blood vessel anastomat. The blood vessel anastomat comprises a first anastomosis plate and a second anastomosis plate, the shapes of the first anastomosis plate and the second anastomosis plate are both annular-shaped, the end face of one side of the first anastomosis plate is provided with a nail butting seat, and the end face of one side of the second anastomosisplate is provided with a nail cabin. The first anastomosis plate and the second anastomosis plate are designed to arc structures to allow the first anastomosis plate and the second anastomosis plateto sleeve the outer side of the blood vessel, when the blood vessel is cut off, the blood vessel at the cutting position is tilted outwards or evaginated along the circumference, the tilted or evaginated blood vessel is built on the first anastomosis plate and the second anastomosis plate, through extrusion between the first anastomosis plate and the second anastomosis plate, the evagination portions of the blood vessel are butted together, the tilted or evaginated portions of the blood vessel are fixed through closed nails in the nail cabin so as to improve the closing speed of the blood vessel and shorten the operation time.

Description

technical field [0001] The invention relates to a stapler, in particular to a blood vessel stapler. Background technique [0002] When anastomosis of large vessels such as liver transplantation, kidney transplantation, heart transplantation, and lung transplantation is performed, the shorter the operation time, the more conducive to postoperative recovery of liver, kidney, heart, and lung transplantation, maintaining systemic circulation as soon as possible, and reducing the risk of complications for patients The incidence rate is conducive to the early resurrection of the graft. The shorter the time, the higher the probability of large organ function recovery, avoiding the occurrence of large organ failure, especially avoiding the occurrence of renal function, liver function, heart function and pulmonary function failure. Provide a powerful weapon to save patients' lives. [0003] However, in the prior art, there is no instrument for the arterial anastomosis of great vesse...
