Description
Technical field
The present invention relates to technical field of medical instruments, particularly the automatic purse-string forceps of one.
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.For patient have less hemorrhage, less operating time in art, with apparatus replace manual thus reduce cause due to craft error, avoid infection, postoperative function recovers the multiple advantage such as fast.
A kind of typical purse-string forceps automatically, first clamps tissue with jaw during operation, then locks notch, and tissue can naturally be clamped and some tissue is clamp-oned in notch space.Simultaneously staple is by suture pressure organizationally, now unclamps notch, lift apparatus, suture can along staple the track followed closely out with apparatus, one segment length is proposed, then play pocket.The operative site that this apparatus is limited to for positions such as rectum resection or esophagus excisions, there is very large shortcoming: first suture can only lift along organ-tissue cross section, this is with just requiring there is suitable working place, otherwise being easy to oblique loading makes staple depart from tissue, cause playing pocket failure, staple may be caused to fall in human body, because of position limitation and staple is very little, be not easy the staple finding to drop, staple finally may be caused to stay in body, may cause life threat to patient, the safety of automatic purse-string forceps is unreliable.
Therefore, how making automatic purse-string forceps complete operation more safely and reliably, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The object of this invention is to provide a kind of purse-string forceps automatically, this automatic purse-string forceps can complete operation more safely and reliably.
To achieve these goals, the invention provides a kind of purse-string forceps automatically, comprise device body, also comprise the arm shaft that is all connected with the central shaft of described device body and cam, the suture needle be connected with described arm shaft, be arranged on described device with it and with the sliding connection block of described cam engagement, described sliding connection block is provided with connection fixture block, the suture end of described automatic purse-string forceps is provided with suture cover, and described suture cover can be arranged on described connection fixture block, and the needle point of described suture needle is hook-shaped.
Preferably, described suture tackling is flexible.
Preferably, described connection fixture block 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 device body, also comprise the arm shaft that is all connected with the central shaft of described device body and cam, the suture needle be connected with described arm shaft, be arranged on described device with it and with the sliding connection block of described cam engagement, described sliding connection block is provided with connection fixture block, the suture end of described automatic purse-string forceps is provided with suture cover, described suture cover can be arranged on described connection fixture block, and the needle point of described suture needle is hook-shaped.
Operationally, first tissue is placed on suture needle place, the handle of rot body, centre axis movable pendulum arm axle and cam rotate, and arm shaft drives suture needle through tissue, while the needle point of suture needle is overlapped by suture, the bossing of cam and sliding connection block collide, promote sliding connection block radial motion, the sideline, side that suture is overlapped enters in the hook-shaped needle point of suture needle, rotates stopping and putting in place.
Then counter-rotation device body handle, because the needle point of suture needle has caught on suture cover, so suture needle can drive suture to pass tissue get back to original state, then carries out next step operation.
Known by foregoing description, relative to background technology, this automatic purse-string forceps does not use staple, makes suture pass tissue to complete operation, avoids the phenomenon that staple drops, make automatic purse-string forceps can complete operation safely and reliably.

Detailed description of the invention
Core of the present invention is to provide a kind of purse-string forceps automatically, and this automatic purse-string forceps can complete operation more safely and reliably.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-Fig. 6, in a kind of detailed description of the invention, automatic purse-string forceps provided by the invention, comprise device body, also comprise the arm shaft 6 that is all connected with the central shaft 5 of device body and cam 1, the suture needle 4 be connected with arm shaft 6, be arranged on the sliding connection block 2 that device coordinates with it and with cam 1, sliding connection block 2 is provided with and connects fixture block 21, suture 3 end of automatic purse-string forceps is provided with suture cover 31, suture cover 31 can be arranged at and connect on fixture block 21, and the needle point of suture needle 4 is hook-shaped.
Operationally, original state, as shown in Figure 3, is first placed on suture needle 4 place by tissue, the handle of rot body, central shaft 5 drives arm shaft 6 and cam 1 to rotate, and arm shaft 6 drives suture needle 4 through tissue, and the needle point of suture needle 4 is by while suture cover 31, bossing and the sliding connection block 2 of cam 1 collide, promote sliding connection block 2 radial motion, the sideline, side making suture overlap 31 enters in the hook-shaped needle point of suture needle 4, rotates stopping and putting in place.Then counter-rotation device body handle, because the needle point of suture needle 4 has caught on suture cover 31, so suture needle 4 can drive suture 3 to get back to original state through tissue, as shown in Figure 4, has then carried out next step operation.This automatic purse-string forceps does not use staple, makes suture 3 pass tissue to complete operation, avoids the phenomenon that staple drops, make automatic purse-string forceps can complete operation safely and reliably.
In addition, suture cover 31 has elasticity, and suture cover 31 has elasticity can make suture cover 31 be arranged on after on connection fixture block 21, difficult drop-off.Ensure that, when performing the operation, suture needle 4 can overlap 31 coordinate accurately with suture.
In addition, connect fixture block 21 and there is elasticity, connection fixture block 21 has elasticity can make suture cover 31 more conveniently install, and suture cover 31 can be made can not to come off relative to connection fixture block 21, ensure that suture needle 4 can overlap the cooperation of 31 accurately in suture when performing the operation.
Further, suture needle 4 is threaded with arm shaft 6, and suture needle 4 is threaded with described arm shaft 6 and is convenient to install, and suture needle 4 is reliable with the bonding strength of described arm shaft 6, and ensure that the reliable of operation, suture needle 4 also can be welded on shown arm shaft 6.
Above automatic purse-string forceps provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
