Description
Technical field
The utility model is related to a kind of medical surgery surgical instrument implantation material and its Special surgical instrument, espespecially a kind of blood vessel
Stapling apparatus and cooperation Special surgical device.
Background technology
Vascular anastomosis technology is considered as the foundation stone of microsurgery, and the discipline range being related to is wide, and identical relationship between quality arrives
The success or failure of operation.Vascular anastomosis method can be divided into needlework sewing and Sutureless jacquard CAD two major classes, traditional small vessel anastomosis
Method is end-to-end interrupted suture, but there are many shortcomings for this method：It is cumbersome, take long, thin vessels
Restenosis problem etc. after coincideing.Sutureless jacquard CAD can be summed up：Embedding inosculating method, heat setting jacquard CAD, bonding jacquard CAD and
Mechanical anastomosis method.It includes being inserted in sutured anastomosis method and being inserted in bonding jacquard CAD that blood vessel, which is inserted in jacquard CAD, compared with sutured anastomosis method
Compared with embedding inosculating method blood vessel internal membrane damage is light, and sewing needle number is few, and the time that coincide is short.But there is also the defects that can not be ignored：Closely
End blood vessel must be inserted into distal vessels, this operation is relatively complicated；Blood vessel needs enough length, not when coincideing tensioned
Preferably use；Outer diameter<The blood vessel of 1mm is not suitable for the jacquard CAD.Laser heat setting jacquard CAD is made using the laser thermal effect of low-power
The elastomer and collagenous fibres of externa and middle film become gel state from collosol state and make blood vessel " welding ".Bonding kiss
Legal is that the blood vessel both ends of close apposition are glued together using adhesive of medical to make vascular anastomosis.No matter which kind of bonding is used
Agent, it is necessary to be smeared again after blood vessel close apposition and adhesive is avoided to enter lumen of vessels.In addition, previous anastomotic elasticity after bonding
Difference, matter are crisp, and adhesive has certain toxicity, and blood vessel both ends need to be maintained open state by when bonding, prevent from collapsing, it is therefore desirable to first
Blood vessel or built-in hollow stent are drawn in suture needle.
Blood vessel machinery jacquard CAD is the vascular anastomosis method that suture is substituted or partly replaced with special vascular anastomosis device,
Also referred to as blood vessel anastomat method is the identical method of Sutureless of domestic and international most study.Modern mechanical vascular anastomosis method is by kiss
Tiretube process, magnetic tube method, anastomosis clamp method and needle ring method can be divided by closing principle.The application of mechanical vascular anastomosis significantly simplifies
Surgical procedure shortens operating time, reduces tissue damage bleeding and postoperative infection chance in art, makes some in usual conditions
Under it is impracticable operation carried out.Blood vessel anastomat as described in CN85106639B, is docked by Special surgical instrument
It coincide, easy to operate, it is firm to coincide.But their existing greatest problems are exactly that anastomosis ring/wheel or draw point be not biodegradable, kiss
Previous anastomotic and surrounding are for good and all stayed in after the completion of closing, caused inflammatory reaction is even heavier than conventional suture method.
There is different defects, a kind of simple, quick and safe blood vessel kiss in view of current existing vascular anastomosis method
Conjunction method is particularly important.
