Abstract
An auxiliary peripheral vascular anastomat relates to medical equipment, and comprises a body and an end part, wherein the surface of the body is smooth and has no concave-convex rough protrusions formed thereon; the end part is a bullet-like and spherical cap shaped cone head; the end part is in smooth transition with the body; both the end part and the body can be made into a solid body or a hollow body; the whole shape can be straight, curved or T-shaped with branches; the normal length is 10 to 75 millimetres; the bending angle and the branching angle range from 0 degree to 90 degrees; andserial instruments are made according to diameters of a blood vessel and an tubular organ inner membrane. The blood vessel and tubular organ dilatation anastomat can eliminate the collapse of a lumenwith broken ends, and avoid the transplacement and the distortion of the lumen with the broken ends; and the sutura difficulty of the lumen with the broken ends is greatly reduced, the operating timeof the whole operation is obviously shortened, and the involution accurate rate and the anastomosis patency rate are remarkably improved. The instrument is a disposable contra-aperture dilatation andanastomosis instrument series with generality, wide application, simplicity and convenience.
Description
Technical field
What this utility model related to is medical apparatus and instruments, particularly relates to the auxiliary anastomat of peripheral vessels.
Background technology
In surgery clinical medicine and zoopery vascular medicine field, human body or animal body blood vessel and pipe surgical stapling generally adopt simple maneuver that end end boil on the nape opposite the mouth coincide and socket, method such as bonding; The inner support surgical stapling method of hollow solubility biomaterial as liner that adopt also arranged.With regard to the vascular anastomosis technology, simple maneuver operation technique exists: 1. involutory big with the anastomosis difficulty, especially internal diameter is 1～1.5 millimeter little blood vessel and little pipe, the quality instability of coincideing, there is the quality unstable factor too in same exactly position doctor's multi-pass operation, that abandons performing the operation is of common occurrence for this reason, therefore, the requirement person of performing a surgical operation has quite skilled operating technology, and need have more rich clinical experience, the abecedarian more need be through long-term specialized operations training, and the doctor that older vision is not good enough can't participate in the identical operation of clinical blood vessel.2. the slow and length consuming time of performing the operation of speed of operation.And adopt hollow solubility biomaterial still can not overcome the defective of simple maneuver operation technique fully as the inner support surgical stapling method of liner.Improper easy generation tube chamber twists, subsides in case the solubility inner support melts, thromboembolism, and secondary injury blood vessel; Often be difficult to tidy up lost game behind the operative failure; So vascular patency is not high, extensively promote acquiring a certain degree of difficulty.Moreover solubility biomaterial inner support cost and expense are higher relatively, have also increased patient's burden.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, in Clinical Surgery's medical science and zoopery medical domain, human body or animal body blood vessel and pipe surgical stapling method provide a kind of general, simple, convenient, widely used peripheral vessels to assist anastomat.To reach the shortening operation time, carry the patency rate after involutory accurate rate and the vascular anastomosis.
This utility model is to realize by following technical measures.A kind of peripheral vessels is assisted anastomat, comprises end, end and the body rounding off of spherical crown shape conehead like the body of the coarse projection of smooth surface no concave-convex and the sub warhead.
Described body and end are solid objects.
Described body and end are hollow objects.
Described body is that total length is 10～75 millimeters a straight type object.
Described body is that total length is 10～75 millimeters, and to have angle of bend be 0 °～90 ° flexure type object.Bending point can be in the optional position of body.
Described body is that a length is 10～75 millimeters, and to have flexible angle, two ends be the support body that 0 °～90 ° bending type support body and another length are 5～37.5 millimeters, and between two support bodies angle be 0 °～90 ° the T of branch type object arranged.The cross point of two support bodies can be in the optional position of body.
Described body and end can be carried out the material of sterilization and be made by avirulent.
When carrying out human body or animal body blood vessel and pipe surgical stapling, elder generation is with the debridement of broken ends of fractured bone tube chamber, port correction or cut flat, then with the auxiliary anastomat of the suitable peripheral vessels of the identical lumen diameter end of inserting tube chamber, as required behind blood vessel dilating and the pipe, make that the tube chamber broken ends of fractured bone is involutory to be closed up, broken ends of fractured bone tube chamber is by the auxiliary anastomat of peripheral vessels and be full shape.The broken ends of fractured bone tube chamber boil on the nape opposite the mouth location inserting needle that is full shape, boil on the nape opposite the mouth is sewed up, wouldn't take-up tie a knot after finishing, earlier the auxiliary anastomat of peripheral vessels is taken out from the gap of vessel end and ends of vessels, check anastomotic stoma then, anti-freezing liquid flushing anastomotic stoma, take-up knotting anastomosis of blood vessel and pipe again, the whole surgery anastomosis procedures promptly comes to an end.Just in case it is undesirable to coincide, angiostomy can also repeat, and can not influence identical quality, also can secondary injury blood vessel and pipe.
The auxiliary anastomat of peripheral vessels can be made serial apparatus product, many different shapes and specification are arranged, in the process of expansion of blood vessel and pipe operation, can change one of them model of selecting the auxiliary anastomat series of suitable peripheral vessels arbitrarily, satisfy the needs of actual operation by blood vessel and pipe endocardial wall diameter.
After this utility model adopts abovementioned technology,, also can avoid the phenomenons such as dislocation, distortion of broken ends of fractured bone tube chamber because that the auxiliary anastomat of peripheral vessels to the filling of broken ends of fractured bone tube chamber, can not take place by collapsing of broken ends of fractured bone tube chamber is flat.Coincideing of the thin blood vessel in extremity end can cooperate 2～10 times of operating loupes.Adopt the difficulty of carrying out broken ends of fractured bone tube chamber operation stitching art behind the auxiliary anastomat of peripheral vessels greatly to reduce, especially the easier association of abecedarian grasps, and the high age and service seniority doctor of general vascular anastomosis technology is arranged, and uses this technology can be more handy.Can injured blood vessel and pipe inner membrance during operation, can improve the survival rate and the patency rate of operation back corresponding organ to greatest extent.The whole surgery operating time obviously shortens, and involutory accurate rate and identical patency rate are significantly increased.The doctor can be familiar with this apparatus within a short period of time, accurate rate and identical patency rate can reach 100%, and the auxiliary anastomat series of peripheral vessels is the disposable surgical instruments that a kind of general, widely used, simple and convenient, suitable various blood vessels and the expansion of pipe boil on the nape opposite the mouth coincide.
