Operation principle of the present utility model is as follows: before using, guid needle is in hollow pipe, during use, guid needle sent and enter tissue, guid needle reverts to circular arc after departing from constraint and passes from opposite side tissue to be stapled, then suture is entered from guid needle one end, pass along guid needle endoporus from the other end, exit reverse for guid needle after fixing suture termination, suture is stayed in tissue, by suture two the end of a thread knottings, complete stitching.
Further, described hollow pipe rear end connects plunger shaft, and described plunger shaft is furnished with push rod, plunger shaft front end is provided with axially extending bore A, push rod is provided with axially extending bore B, described axially extending bore A, axially extending bore B, hollow pipe dead in line, and described guid needle rear end connects push rod.Release guid needle by push rod, during use, the front end of hollow pipe approaches tissue to be stapled, presses push rod and is released forward by guid needle.
Further, this utility model also comprises nook closing member, and described nook closing member and guid needle inwall adaptation, nook closing member leading portion, the form of guid needle 1 leading portion when unconfinement state are with identical.The effect increasing nook closing member is, guid needle can obtain larger puncture force and the stability that better punctures, and reduces penetration Resistance, reduces the damage of piercing process to tissue.
Preferably, put the first edge on a knife or a pair of scissors in the front end of described hollow pipe.Be applicable to be stapledly to use when organizing side textura epidermoidea thicker, hollow pipe adopts the material larger than guid needle Rigidity and strength to make, and during use, adopts plunger shaft front end to pierce through thicker textura epidermoidea.
Preferably, described hollow pipe, axially extending bore A, axially extending bore B all have two, have guid needle at least one hollow pipe; Wherein a kind of optimal way: guid needle has one, guid needle is constrained in one of them hollow pipe, and under unconfinement state, the circular arc span of guid needle equals the distance between two axially extending bore A.Be applicable to use when the both sides textura epidermoidea of tissue to be stapled is all thicker.During use, two hollow pipes pierce through the both sides textura epidermoidea of tissue to be stapled respectively, dock form complete through suture channel after guid needle passes from axially extending bore A and hollow pipe with another hollow pipe.Another kind of optimal way: described guid needle has two, is constrained in two hollow pipes respectively, under unconfinement state, the circular arc span after two guid needle docking equals the distance between two axially extending bore A.Be applicable to use when the both sides textura epidermoidea of tissue to be stapled is all thicker, during use, two hollow pipes pierce through the both sides textura epidermoidea of tissue to be stapled respectively, and after two guid needles pass respectively from two axially extending bore A and hollow pipe, between two hollow pipes, docking forms complete through suture channel.
Further, described hollow pipe front end is angle, and the angle of two hollow pipes is relative.Be conducive to docking or the docking of two guid needles of guid needle and offside hollow pipe.
Preferably, described axially extending bore A, axially extending bore B all have two, and described hollow pipe is coaxial with one of them axially extending bore A, and the front opening of another axially extending bore A is horn mouth.Under unconfinement state, the circular arc span of guid needle equals the distance between two axially extending bore A, and guid needle is arranged in the plunger shaft of putting the first edge on a knife or a pair of scissors front end, and after guid needle is pushed out, its front end is docked with horn mouth and formed suture channel.
Preferably, the material of described guid needle is memorial alloy.Preferably select to be at normal temperatures the memorial alloy of the superlastic state that phase in version has occurred.
Further, described plunger shaft rear end is provided with outside flange, and described putting back-end is provided with and pushes away handle.Handled easily.
Further, this utility model also comprises suture, and described suture is the multiply braided suture that sub-thread suture or front end do that rigidity strengthens process.
This utility model can complete the sew application of MED Post operation fibrous ring fast, and product structure is simple, and easy to operate, sewing effect is good.Certainly, this utility model also can be used for the sew application of other Minimally Invasive Surgerys.
