Description
Technical field
The present invention relates to technical field of medical instruments, particularly a kind of automatic purse-string forceps.
Background technology
In medical science applied surgical operation, since 20th century invention sixties first staple series products, Medical stapler has become the requisite a kind of medical apparatus and instruments aided in edge of a knife sewing process.Along with development and the research and development of products of medical science, more and more multi-functional staple series products is applied to clinical.The scope of application has related to the every field such as gastrointestinal surgery, Genneral Surgery, thoracic surgery, Urology Surgery, department of obstetrics and gynecology, becomes one of requisite instrument of doctor.Thereby for the patient have less hemorrhage, less operating time in art, with apparatus replace reducing due to error that craft causes by hand, avoid infection, postoperative function recovers the multiple advantage such as fast.
A kind of typical purse-string forceps automatically, first clamp tissue with jaw during operation, then locks notch, and clamped and some tissue of tissue meeting nature is clamp-oned in the notch space.Staple is pressed suture organizationally simultaneously, now unclamps notch, lifts apparatus, and the track that suture can be followed closely out along staple proposes a segment length with apparatus, then plays pocket.The operative site that this apparatus is limited to for positions such as rectum resection or esophagus excisions, have very large shortcoming: at first suture can only lift along the organ-tissue cross section, this just requires that suitable working place must be arranged, otherwise being easy to oblique loading breaks away from staple and tissue, cause beating the pocket failure, may cause staple to fall in human body, because of position limitation and staple very little, be not easy to find the staple dropped, finally may cause staple to be stayed in body, to patient, may cause life to threaten, the safety of purse-string forceps is unreliable automatically.
Therefore, how making automatic purse-string forceps complete more safely and reliably operation, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The purpose of this invention is to provide a kind of automatic purse-string forceps, this automatic purse-string forceps can complete operation more safely and reliably.
To achieve these goals, the invention provides a kind of automatic purse-string forceps, comprise the device body, also comprise the arm shaft and the cam that all are connected with the central shaft of described device body, the suture needle be connected with described arm shaft, be installed in described device moving slider with it and card line slide block, described moving slider and described device body are slidably connected and can make described card line slide block move down, described card line slide block is provided with the suture needle hole, the inboard in described suture needle hole is provided with the suture grooving, the suture end of described automatic purse-string forceps is provided with the suture cover, described suture cover is arranged in described suture grooving, the top in described suture needle hole is provided with breach.
Preferably, described moving slider Jin center axle head is provided with the inclined-plane towards described cam lobe direction.
Preferably, described moving slider Jin center axle head be shaped as circular-arc.
Preferably, the sliding end of described card line slide block be shaped as circular-arc.
Preferably, described moving slider Yuan center axle head is provided with the inclined-plane towards described card line slide block.

Preferably, described suture tackling is flexible.
Preferably, described suture grooving has elasticity.
Preferably, described suture needle is threaded with described arm shaft.
Preferably, described suture needle is welded on described arm shaft.
Automatic purse-string forceps provided by the invention, comprise the device body, also comprise the arm shaft and the cam that all are connected with the central shaft of described device body, the suture needle be connected with described arm shaft, be installed in described device moving slider with it and card line slide block, described moving slider and described device body are slidably connected and can make described card line slide block move down, described card line slide block is provided with the suture needle hole, the inboard in described suture needle hole is provided with the suture grooving, the suture end of described automatic purse-string forceps is provided with the suture cover, described suture cover is arranged in described suture grooving, the top in described suture needle hole is provided with breach.
When work, first tissue is placed on to suture needle place, the handle of rot body, central shaft drives arm shaft and cam rotates, arm shaft drives suture needle through tissue, the needle point of suture needle is by the suture needle hole, the bossing of cam and moving slider collision, promote moving slider radially away from central shaft, thereby moving slider push card line slide block, move downward card line slide block, because the top in suture needle hole is provided with breach, so the needle point of suture needle can catch on the suture cover of suture hole gap portions, rotation stops putting in place.
Then counter-rotation device body handle, because the needle point of suture needle has caught on the suture cover, get back to original state so suture needle can drive suture through tissue, then carries out next step operation.
Known by foregoing description, with respect to background technology, this automatic purse-string forceps is not used staple, makes suture pass tissue and completes operation, and the phenomenon of having avoided staple to drop, make automatic purse-string forceps can complete safely and reliably operation.
