Description
Technical field
This utility model relates to the curved cutter stapler field, specifically, relates to a kind of cutting mechanism for arc cutting stitching instrument.
Background technology
Curved cutter stapler excises before mainly being suitable for the rectum low level.In order to enter the lower position of pelvic cavity, we have developed curved cutter stapler, the design of this apparatus can better expose anatomical structure, be convenient to the deep operation, the dissect physiology that more complies with the nature when the doctor operates, lower position can go deep into basin in the excision before the rectum low level at the bottom of is even enter narrow and small pelvis.The more important thing is that this apparatus can be finished and sew up and cutting in once-through operation, simplified the step of rectum distal resection.This apparatus meets body mechanics's engineering design, can one hand closes and cuts, and one hand is pushed positioning needle, is convenient to the another hands and carries out the pelvic cavity operation.
Curved cutter stapler mainly comprises nail bin, nail supporting base closure, reaches anastomosis staple, blade percussion portion.In the percussion portion of apparatus in the past, because anastomosis staple and blade synchronous shift, cutting blade is sewed up faster than anastomosis staple and is cut off tissue earlier, Elastic tissue will be not fully the anastomosis staple of sew bring human body into, come risk to surgical band.Former apparatus has comprised a close handles, firing handle and apparatus shell handle, if add the separation that a handle is used to sew up cut-out again, it is very loaded down with trivial details that this apparatus shows, and is not easy to doctor's operation.If blade height is dwindled, allow the anastomosis staple height be higher than blade height, but the tissue thickness of this apparatus clamping can be affected during operation, blade will lose the acoustic effect that cuts off the pad knife plate when the low bit manipulation of pelvic cavity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cutting mechanism for arc cutting stitching instrument is provided, and after this mechanism can realize the complete suture tissue of anastomosis staple, blade cut off the function of tissue again.
The technical scheme that realizes above-mentioned purpose is: a kind of cutting mechanism for arc cutting stitching instrument, comprise nail supporting base, nail bin, blade, blade bearing, side plate, supporting plate, promote mainly plate, secondary push pedal, push jack and firing handle, firing handle with promote mainly plate and flexibly connect, blade is installed on the blade bearing, blade bearing with promote mainly plate and fixedly connected, push jack is fixedly mounted in the secondary push pedal, secondary push pedal has two and link together by rivet pin, promote mainly plate between two secondary push pedals, secondary push pedal is inserted on the side plate, and supporting plate has two and be positioned at the side plate outside, and two supporting plates connect by rivet pin, also comprise link rod plate, have the track groove on the supporting plate, with to promote mainly plate hinged, link rod plate is connected with supporting plate by pin link rod plate by pin, and pin is positioned at the track groove of supporting plate, and link rod plate is hinged by pin and secondary push pedal.
After adopting technique scheme, stir firing handle, promotion is promoted mainly plate and is moved forward, link rod plate is under the pulling of promoting mainly plate, drive secondary push pedal and move, move in the track groove of the pin in the track groove in supporting plate, the pin that is connected with secondary push pedal is swung forward, this track groove can order about and drive secondary push pedal under the situation of promoting mainly plate and have little displacement and produce big displacement as calculated, and the secondary push pedal of its displacement official post promotes push jack and allows the anastomosis staple molding earlier.This moment, push jack was subjected to the nail supporting base obstruction to stop to move forward, promoting mainly plate continues to move forward, on the link rod plate with promote mainly the pin that pin that plate is connected drives in the track groove and in the track groove, slide, the pin that is connected with secondary push pedal on the link rod plate is then done vertical slip, and the blade of promoting mainly on the strip moving knife seat is finished the tissue cutting.This structure has been avoided blade and anastomosis staple synchronous unique risk of bringing in operating process, and can finish safely and effectively to close and cut, and the operation practical simplicity.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Shown in Fig. 1～10, a kind of cutting mechanism for arc cutting stitching instrument, comprise nail supporting base 1, nail bin 2, blade 3, blade bearing 5, side plate 7, supporting plate 12, promote mainly plate 11, secondary push pedal 10, push jack 4 and firing handle 13, firing handle 13 is hinged by pin 14 and supporting plate 12, and firing handle 13 upper ends with promote mainly plate 11 and flexibly connect, blade 3 is installed on the blade bearing 5, blade bearing 5 with promote mainly plate 11 and fixedly connected, push jack 4 is fixedly mounted in the secondary push pedal 10, secondary push pedal 10 has two and link together by rivet pin 8, promote mainly plate 11 between two secondary push pedals 10, secondary push pedal 10 is inserted on the side plate 7, and supporting plate 12 has two and be positioned at side plate 7 outsides, and two supporting plates 12 connect by rivet pin 6, also comprise link rod plate 15, have the track groove on the supporting plate 12, with to promote mainly plate 11 hinged, link rod plate 15 is connected with supporting plate 12 by pin 19 link rod plate 15 by pin 9, and sell the 19 track grooves that are positioned at supporting plate 12, link rod plate 15 is hinged with secondary push pedal 10 by pin 16.
