Described propelling groove equidistance is provided with.
Described band cutter tooth bar is provided with at least three and advances groove.
After adopting such design, the present invention adopts push broach connecting rod and the drive mechanism that band cutter tooth bar cooperates, and can realize the step-by-step movement control of pulling the trigger, cutting; And can accomplish percussion and cutting through pressing operation, and easy to operate, be applicable to the open surgery that intestinal, stomach excise; Being particularly useful for little otch, adiposis patient contracts in the operations such as stomach and stomach turn of tidal stream (GBP); Compact conformation, reasonable, flexibly light and handy, a hands can be accomplished the cutting and stitching operation; And the operator can directly touch wound hardly, thereby is more suitable for promoting the use of.
Description of drawings
Above-mentioned only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed description.
Fig. 1 is a kind of structural representation that adopts the straight cuts stiching instrument of novel transmission mechanism of the present invention.
Fig. 2 is the perspective structure sketch map that the present invention adopts the straight cuts stiching instrument of novel transmission mechanism.
Fig. 3 is a band cutter tooth bar structural representation of the present invention.
The specific embodiment
See also shown in Fig. 1-3, a kind of straight cuts stiching instrument that adopts novel transmission mechanism of the present invention mainly comprises strap 1, nail supporting base assembly 2, closed clamping plate 3 and drive mechanism.
Drive mechanism comprises support link 41, push broach connecting rod 42 and band cutter tooth bar 43.
Wherein, the rear end or the rear portion of the rear end of support link 41 and strap 1 are rotatably connected, and the rear end of the front end of support link 41 and push broach connecting rod 42 is rotatably connected, push broach connecting rod 42 can before and after slide be installed in the closed clamping plate 3.Band cutter tooth bar 43 can before and after slide be installed in the strap 1, and cutting knife 431 and percussion push jack 432 are installed at front end, the middle part is provided with and advances groove 433.The front end of push broach connecting rod 42 can be stuck in the propelling groove 433 of band cutter tooth bar 43, and forward end promotes band cutter tooth bar 43 when carrying out percussion, cutting action.Because the drive mechanism that adopts the push broach connecting rod to cooperate with band cutter tooth bar is controlled so can realize the step-by-step movement of pulling the trigger, cutting, and can accomplish percussion and cutting through pressing operation, and is easy to operate.
Preferable; The rear end of push broach connecting rod 42 is connected through bearing pin 44 with the front end of support link 41; And offer chute 31 in closed clamping plate 3 sides, in closed clamping plate 3 set inside restriction push broach connecting rod 42 range of activity, particularly move up and down the positioning bar of scope, bearing pin 44 slides in chute 31.
During use; Push closed clamping plate 3, support link 41 is that rotate at the center with its rear end, and bearing pin 44 is along chute 31 reaches; The front end of push broach connecting rod 42 moves forward along closed clamping plate 3 thereupon; When touching the propelling groove 433 of band cutter tooth bar 43, will drive cutter tooth bar 43 and move to stiching instrument the place ahead in the lump, realize cutting, sew application thereby drive cutting knife 431 with percussion push jack 432.
In addition, can on band cutter tooth bar 43, a plurality of propelling grooves 433 be set, at least three equidistant propelling grooves 433 of setting for example as shown in the figure.Push for the first time closed clamping plate 3, push broach connecting rod 42 drives the cutting and stitching of first section of band cutter tooth bar 43 completion through propelling groove 433 foremost.Unclamp closed clamping plate 3, band cutter tooth bar 43 is motionless, and push broach connecting rod 42 is return and broken away from band cutter tooth bar 43, pushes closed clamping plate 3 once more, and push broach connecting rod 42 contacts with second propelling groove 433 of band cutter tooth bar 43, and promotes the 43 further reaches of band cutter tooth bar.So repeatedly, can progressively advance cutting knife 431 and percussion push jack 432, what be more conducive to cut, sew up controls.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
