Problems solved by technology

As far as the vascular anastomosis technique is concerned, the simple manual operation has the following problems: 1. The technique of anastomosis and anastomosis is difficult, especially for small blood vessels and small tubular organs with an inner diameter of 1-1.5 mm. The quality of anastomosis is unstable, and the same doctor There are also factors of unstable quality in multiple operations, and it is not uncommon to give up the operation for this reason. Therefore, the operator is required to have quite skilled operation techniques and rich clinical experience, and beginners need to go through long-term special operations. Training, elderly doctors with poor eyesight cannot participate in

Embodiment 1

[0020] Example 1. As shown in Fig. 1, the anastomotic instrument for expansion and anastomosis of blood vessels and tubular organs is a straight object. The body 1 is a solid cylinder, the end 2 is solid inside, and the outside is a spherical cone like a bullet. The total length is 35 millimeters, and the outer diameter of the body 1 can be made into a series of instruments according to the diameter of the intima wall of blood vessels and tubular organs.

[0021] The straight object can also be made into a hollow body.

Embodiment 2

[0022] Example 2. As shown in Fig. 2, the anastomotic instrument for expansion and anastomosis of blood vessels and tubular organs is a curved object. The body 1 is a solid cylindrical body with a curved angle, and the curved angle B is 30°; the end 2 is a bullet-like spherical crown cone. The total length is 55 millimeters, and the outer diameter of the body 1 can be made into a series of instruments according to the diameter of the intima wall of blood vessels and tubular organs. The bending point is at the midpoint of the body.

[0023] The curved object can also be made into a hollow body.

Embodiment 3

[0024] Example 3. As shown in FIG. 3 , the anastomotic instrument for expansion of blood vessels and tubular organs is a T-shaped object with branches. There are two branches on the body 1, one of which is a solid cylinder with a length of 65 mm and a bendable branch 1-1 with a bending angle C of 10° at both ends; the other is a 30 mm long Solid cylinder 1-2, the angle D between the two branches is 60°. The end 2 of each branch is a bullet-like spherical crown cone. The outer diameters of the branch body 1-1 and the branch body 1-2 can be made into a series of instruments according to the diameter of the intima wall of blood vessels and tubular organs. The branch point is at one-half the length of the longer branch.

[0025] The T-shaped object with branches can also be made into a hollow body.

Abstract

A blood vessel and tube expand inosculating apparatus relates to a medical appliance, which includes an arborization noumenon having a glazed surface and no sagging coarse prominency and an end part having a spherical cap conule like the sub warhead, and the end part is slidingly transmitted with the noumenon. The noumenon and the end part can be made into the solid or the hollow body; the whole shape can be divided into the straight shape, the bending shape and the T-shape with a branch, which generally has the length of 10-75 mm, and the bending angle and the branch angle 0-90 DEG, also can be made into the series appliance according to the blood vessel and the tube entooecium diameter. Adopting the blood vessel and the tube expand inosculating apparatus can not generate the shrivelled of the bronken ends of fractured bone, also avoid the phenomena of displacement and distort etc of the broken enos of fractured boneing. So the difficulty to process the broken enos of fractured boneing can be greatly reduced, the time of the operation is evidently shortened, which markedly advances the precision and the inosculating fluent rate. The appliance is the contraaperture expand inosculating disposable appliance series which is universal, widely applicable and simple and convenient.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for expansion and anastomosis of blood vessels and tubular organs. Background technique [0002] In the field of surgical clinical medicine and animal experimental vascular medicine, end-to-mouth anastomosis, socketing, bonding and other methods are generally used for surgical anastomosis of human or animal blood vessels and tubular organs; hollow soluble biomaterials are also used as liners. Surgical anastomosis method of internal stent. As far as the vascular anastomosis technique is concerned, the simple manual operation has the following problems: 1. The technique of anastomosis and anastomosis is very difficult, especially for small blood vessels and small tubular organs with an inner diameter of 1-1.5 mm. There are also factors of unstable quality in multiple operations, and it is not uncommon to give up the operation for this reason. Therefore, the operator is required to have...
