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
What the present invention relates to is medical apparatus and instruments, particularly relates to the apparatus that the expansion of blood vessel and pipe coincide.
Background technology
In orthopaedic surgical operations clinical medicine and the zoopery property 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 of coincideing is unstable; There is the quality unstable factor too in same exactly position doctor's multi-pass operation, and 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 pass 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.
Summary of the invention
The objective of the invention 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 boil on the nape opposite the mouth expending anastomosis tool.To reach the shortening operation time, improve the patency rate after involutory accurate rate and the vascular anastomosis.
The present invention realizes through following technical measures: blood vessel and fistulae expending anastomosis instruments comprise end, end and the body rounding off of spherical crown shape conehead like dendroid body and the sub warhead of the coarse projection of smooth surface no concave-convex.
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 is 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 processed 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 suitable blood vessel of identical lumen diameter and the fistulae expending anastomosis instruments 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 blood vessel and fistulae expending anastomosis instruments and be full shape.Be the broken ends of fractured bone tube chamber boil on the nape opposite the mouth location inserting needle of full shape, boil on the nape opposite the mouth is sewed up; Wouldn't take-up tie a knot after finishing; Earlier blood vessel and fistulae expending anastomosis instruments are 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.
Blood vessel and fistulae expending anastomosis instruments can be processed 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 suitable blood vessel and fistulae expending anastomosis instruments series arbitrarily, satisfy the needs of actual operation by blood vessel and pipe endocardial wall diameter.
After the present invention adopts abovementioned technology,, also can avoid the phenomenons such as dislocation, distortion of broken ends of fractured bone tube chamber because that collapsing of broken ends of fractured bone tube chamber to the filling of broken ends of fractured bone tube chamber, can not take place for blood vessel and fistulae expending anastomosis instruments is flat.Coincideing of the thin blood vessel in extremity end can cooperate 2～10 times of operations to amplify frontal mirror.The difficulty that adopts blood vessel and fistulae expending anastomosis instruments to carry out broken ends of fractured bone tube chamber operation stitching art greatly reduces, and especially the abecedarian learn grasp more easily, and the technological high age and service seniority doctor of general vascular anastomosis is arranged, use should 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 blood vessel and fistulae expending anastomosis instruments series are the disposable surgical instrumenties 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.
