Description
Technical field
The present invention relates to the curved cutter stapler field, specifically, relate 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 objective of the invention is to overcome the deficiencies in the prior art, a kind of cutting mechanism for arc cutting stitching instrument is provided, 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, 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, has the track groove on the supporting plate, link rod plate by first pin with to promote mainly plate hinged, link rod plate is connected with supporting plate by second pin, and second pin is positioned at the track groove of supporting plate, link rod plate is hinged with secondary push pedal by the 3rd pin, move in the described track groove of described second pin in supporting plate, make the 3rd pin swing forward that is connected with secondary push pedal, the track groove can order about to be promoted mainly plate and is having under the situation of little displacement the secondary push pedal of drive produce big displacement, the secondary push pedal of displacement official post of promoting mainly plate and secondary push pedal 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 travel forward, promoting mainly plate continues to move forward, on the link rod plate with promote mainly second pin that first pin that plate is connected drives in the track groove and in the track groove, slide, the 3rd pin that the link rod plate worker is connected with secondary push pedal is done vertical slip, and the blade of promoting mainly on the strip moving knife bar is finished the tissue cutting.
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 of second in the track groove in supporting plate, make the 3rd pin swing forward that is connected with secondary push pedal, 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 second pin that first pin that plate is connected drives in the track groove and in the track groove, slide, the 3rd 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 bar is finished the tissue cutting.The risk that this structure has avoided blade and anastomosis staple to bring synchronously in operating process can be finished safely and effectively to close and cut, and the operation practical simplicity.
