Blood vessel anastomat and application method thereof

Abstract

The invention discloses a blood vessel anastomotic device and its use method, in order to increase the convenience of blood vessel anastomosis operation and reduce the technical risk of blood vessel tearing during the operation. The structure includes: a fixed sleeve, a movable sleeve, and a lock; One end of the fixed sleeve is provided with a limiting shoulder, and the other end of the fixed sleeve is provided with an anastomotic connection end; the movable sleeve is sleeved on the wall of the fixed sleeve, and a hanging pin is provided at the end away from the limiting shoulder; The inner hole of the sleeve and the wall of the fixed sleeve are matched by keys and grooves, and only have the freedom of movement to slide along the axis of the fixed sleeve; the lock is made of elastic material, and its shape is ring-shaped and equipped with In the locking part, the shape of the inner hole of the lock buckle is adapted to the shape of the anastomotic connection end. The use of the above-mentioned blood vessel stapler of the present invention can increase the convenience of the blood vessel anastomosis operation, reduce the operation time of the blood vessel anastomosis, reduce the operation risk, improve the success rate of the operation, and make the operation safer.

Description

technical field [0001] The invention relates to the technical field of blood vessel anastomosis, in particular to a blood vessel stapler and a use method thereof. Background technique [0002] Vascular anastomosis is a surgical technique that connects two blood vessels into one. Vascular anastomosis technology began more than one hundred years ago with the application of manual sutures such as Carrel, A, (1908) and Hopfnet, E, (1903) for vascular grafting and replantation of amputated limbs. After more than one hundred years of development, this The technology has been widely used in various surgical procedures. For example, in many fields such as plastic surgery, hepatobiliary surgery, cardiothoracic surgery, urology, obstetrics and gynecology, vascular anastomosis technology is required. Vascular anastomosis is one of the most important steps in the above-mentioned operation, and its success or failure is directly related to whether the tissue in the operation can surviv...

AI Technical Summary

Problems solved by technology

For the vascular suture anastomosis method, although it is the "gold" standard of vascular anastomosis, it still has the following technical defects: 1. The suture will cause damage to the intima of the vessel; 2. The exposure of the suture in the lumen will interfere with the normal flow of blood ;3. Operations such as inversion of the anastomotic stoma will increase the risk of vascular embolism; 4. The operation is cumbersome and the operation time is long; 5. The personal ability of the doctor is high, and it is difficult to master the essentials of the operation without training in a short period of time; 6. .Surgical quality is easily affected by the doctor's psychological and physiological fluctuations; 7. Blood vessels are elastic, soft, and stretchable human tissues. It is difficult to position them by manual suture, and it is difficult to suture accurately with needles.

Although the application of vascular mechanical nail-and-loop anastomosis can greatly simplify the operation steps and shorten the operation time, there are still the following technical disadvantages: In actual operation, many blood vessels to be connected have obvious differences in diameter. In the mechanical nail-ring anastomosis method, the inner diameters of the two plastic rings must be consistent, which cannot meet the anastomosis requirements when the diameters of the vessel sections are different; when the vessel wall is hung on a small needle, each section of the vessel to be connected needs to undergo Six times of large-distance pulling can complete the fixation operation, which makes the operation more difficult and inconvenient in actual operation, and improper operation can easily cause accidental tearing of blood vessels, and even lead to the failure of the operation in severe cases
