Blood vessel and tubular organ expanding anastomosis instrument

Abstract

The invention discloses a blood vessel and tubular organ expanding anastomosis instrument and relates to medical apparatuses. The blood vessel and tubular organ expanding anastomosis instrument comprises a branch-shaped body and an end part of a bullet head-shaped spherical crown conical head, wherein the branch-shaped body has a smooth surface and does not have concave and convex rough bulges; and the end part and the body are in smooth transition. The body and the end part can be manufactured into a solid body or a hollow body. The instrument can be linear, bent or branched T-shaped in the whole shape. Generally, the length of the instrument is 10 to 75millimetres. The bent angle and the branched angle are 0 to 90 degrees. The instrument can also be manufactured into series instruments according to the diameter of a blood vessel and the inner membrane wall of a tubular organ. Due to the adoption of the blood vessel and tubular organ expanding anastomosis instrument, the collapse of a broken end tubular cavity is not caused, and the phenomena such as malposition, distortion and the like of the broken end tubular cavity can also be avoided. The difficulty of performing a broken end tubular cavity surgical suture is greatly reduced; the operation time of the whole surgery is obviously shortened; and both the apposition suture precision and the anastomosis patency are obviously improved. The instrument is a universal disposable instrument series for apposition expanding anastomosis, which is widely applied, is simple and is convenient to use.

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...

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 clinical vascular anastomosis

2. The operation speed is slow and the operation takes a long time

However, the internal stent anastomosis method using hollow soluble biomaterials as a liner cannot completely overcome the defects of simple manual surgery.

Once the dissolvable internal stent is ablated improperly, the lumen will be distorted, collapsed, embolized, and the blood vessel will be damaged secondaryly; it is often difficult to clean up the defeat after the operation fails; therefore, the vascular patency rate is not high, and it is difficult to widely promote it

Furthermore, the cost and expense of stents in soluble biomaterials are relatively high, which also increases the burden on patients
