Abstract
The invention provides a surgical suturing instrument with a trigger locking device. The surgical suturing instrument comprises a trigger locking plate, a flexible assembly, a connecting rod and a trigger handle. The trigger locking plate is provided with a first projection which divides the uncovered portion on the trigger locking plate into a first portion and a second portion, and the first portion and the first projection constitute a non-barrier channel; the flexible assembly is fixedly mounted on the trigger locking plate; the connecting rod compresses the flexible assembly in the closing process of the surgical suturing instrument so as to trigger the locking plate to rotate; the trigger handle departs from the trigger locking plate along the non-barrier channel after finishing and releasing the closing process of the surgical suturing instrument, slides into the trigger locking plate along the channel constituted by the second portion and the first projection in the trigger process after closing, and then is clamped with the trigger locking plate. The structure of the trigger lock plate is changed, the projection on the trigger lock plate no longer prevents the sliding of a lock pillar, and the non-barrier channel in the trigger lock plate enables the trigger lock plate slide out of the lock pillar smoothly.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of surgery suturing appliance with percussion locking system.
Background technology
In medical science applied surgical operation, since the first staple series products of the sixties in 20th century, medical suturing instrument has become the requisite a kind of medical apparatus and instruments that aids in the edge of a knife sewing process.Various surgeries just are being widely used in sewing up human body alimentary canal tissue, respiratory tissues and vascular tissue with medical suturing instrument in surgical operation, can reduce operating time, improve the operation quality.They are normally used for the ends such as esophagus in the digestive tract, Stomach duodenum, small intestinal, coton and rectal end, distolateral and side-to-side neurorrhaphy operation or hemorrhoid excision stomach function regulating pylorus and the operation that forms passage or close incisions such as make mouthful, also be used to the suture operation of the suture operation such as lung and trachea and vascular tissue in the respiratory tract, be specially adapted to appear the suture operation with the Organ and tissue of operating difficulties.
When using the stiching instrument suture tissue, at first, when stiching instrument was in original state, nail supporting base separated with nail bin groupware, and tissue to be sewed up is placed between nail bin groupware and the nail supporting base; Then, hold firing handle, so that nail bin groupware draws close to the nail supporting base direction, and release staple in the nail bin groupware by the effect of propulsion plant, thereby finish sew application; At last, decontrol firing handle and press SR, propulsion plant returns to original state with nail bin.
The percussion locking system of existing surgery suturing appliance is had relatively high expectations to part processing precision, as shown in Figure 1, percussion locking plate 1 of the prior art has " J " shape projection 11, " J " shape projection 11 will be pulled the trigger locking plate 1 and be divided into chute 12 and chute 13, chute 12 does not communicate with the bottom 14 of percussion locking plate 1, after finishing closure, the lock post of firing handle is crossed the lower semisection 111 of " J " shape projection 11 and the percussion locking plate that slips away along chute 12, when percussion, finish percussion and locking along chute 13,, the lock post that has sometimes firing handle is stuck in the problem of 12 li of chutes but can't crossing the lower semisection 111 of " J " shape projection 11, but the lower semisection 111 of " J " of the prior art shape projection 11 can not remove, in case when percussion firing handle lock post go back along chute 12 again, finish percussion and locking and can't enter smoothly chute 13.
In addition, based on the above-mentioned technical problem that solves prior art, application number is that 201210501616.8 patent application had proposed a kind of technical scheme, solved defective of the prior art, but technical scheme is complicated, need to change the structure of connecting rod, the lock post of finishing on the firing handle by percussion locking plate and the cooperation of connecting rod and the extension spring of percussion locking plate enters different slideway on the percussion locking plate, so still remain to be proposed a kind of new technical scheme, can address the deficiencies of the prior art, structure is relatively simple again.
