The specific embodiment
Core of the present invention is to provide a kind of indicating device with the cutter stiching instrument, and this indicating device with the cutter stiching instrument can judge whether the cutting process with the cutter stiching instrument completes accurately.Another core of the present invention is to provide a kind of band cutter stiching instrument that comprises above-mentioned indicating device.
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-Fig. 9, in a kind of specific embodiment, indicating device with the cutter stiching instrument provided by the invention, comprise the fixed mount 2 be arranged on on the clamping plate of cutter stiching instrument, be arranged on fixed mount 2 and can indicate frame 3 with respect to moving of fixed mount 2 motions, the indicating window 4 be connected with fixed mount 2, be arranged on fixed mount 2 and an end and mobile elastic component 21 of indicating frame 3 to be connected, the connecting rope 5 be connected with fixed mount 2 and be arranged at the slip fixture block 1 with nail bin frame 8 inside of cutter stiching instrument, slip fixture block 1 is provided with elastic bumps 11 and an end is connected with connecting rope 5.
During band cutter stiching instrument original state, indicating window 4 is shown in green, slip fixture block 1 is arranged in the position of the 1b of Fig. 8, and connecting rope 5 is in Pre strained state, nail bin 7 is put into to nail bin frame 8 and can block the elastic bumps 11 nail bin framves 8 of slip fixture block 1, hold fixed handle, nail bin 7 travels forward, and drives slip fixture block 1, and slip fixture block 1 drives mobile indication frame 3 by connecting rope 5 and travels forward, thereby indicating window 4 demonstrations become redness by green, and the fixture block 1 that now slides is arranged in the position of the 1a of Fig. 8.
In cutting process, hold fixed handle tissue is carried out to cutting and stitching, when cutting completes, cutter 6 arrive the bottom of nail bin framves 8, the elastic bumps 11 of cutter 6 extruding slip downwards fixture block 1, thus the fixture block 1 that makes to slide breaks away from the constraint of nail bin 7, under the effect of elastic component 21, slip fixture block 1 is retracted to initial position, indicating window 4 is shown in green, and cutting process finishes, thereby carries out next step operation.
Indicating device with the cutter stiching instrument provided by the invention, the cutter 6 that arrange just can touch slip fixture block 1 after cutting finishes, make mobile indication frame 3 motions, thereby make the operator observe change color from indicating window 4, judge whether cutting process completes, guaranteed that cutting process thoroughly completes, avoided the generation of malpractice.Above-mentioned elastic component 21 can be spring, above-mentioned connecting rope 5 can be by being welded to connect with above-mentioned slip fixture block 1, above-mentioned connecting rope 5 can be by being welded to connect with above-mentioned mobile indication frame 3, the both sides of above-mentioned fixed mount 2 can be provided with sliding eye 25, be provided with the locating part 32 coordinated with sliding eye 25 on mobile indication frame 3, above-mentioned connecting rope 5 can be steel wire rope.
