In the initial state or the cutting-completed state, a portion of the blade part 51 is located in the groove 423, that is, the cutting edge 510 is located in the groove 423 and faces the bottom of the groove 423, so that the cutting edge 510 faces downward without being exposed as shown in fig. 5 and 6, and thus the tissue is not damaged. The recess 423 has two opposite groove walls 424, the two groove walls 424 are respectively provided with a receiving hole 425, the cartridge module 30 further includes a rod member 70, the rod member 70 is disposed through the first portion 54 of the through groove 53 and the ends of the rod member 70 are respectively mounted in the receiving holes 425 of the two groove walls 424, when the rod member 70 is located in the first portion 54 of the through groove 53, the cutting knife 50 can rotate around the rod member 70 along a first direction or a second direction, and the first direction is opposite to the second direction. The push-type broach element 60 includes a main body portion 61 and an additional portion 62 extending from a front side surface of the main body portion 61, the main body portion 61 is provided with a first concave portion 63 formed by being recessed inward from the front side surface thereof, an opening of the first concave portion 63 is provided toward the additional portion 62, an inner wall surface of the first concave portion 63 is an arc surface, and the additional portion 62 is provided with a second concave portion 64 formed by being recessed downward from a top surface thereof.
When the nail bin assembly 30 is used, firstly, the cover body on the nail bin 40 is removed, and then the nail bin assembly 30 in the initial state is installed into the nail bin base 10, specifically, the nail bin assembly 30 is installed into the nail bin base 10 by firstly installing the rear end of the nail bin assembly 30 in an inclined downward direction, and then the rear end of the nail bin assembly 30 is used as a pivot shaft, and the rest part of the nail bin assembly 30 is installed into the nail bin base 10 in a pivot mode. When the cartridge assembly 30 is installed in the cartridge seat 10, the circular arc corner 521 of the base 52 of the cutter 50 abuts against the first recess 63 of the body 61 of the pusher 60, during the pivotal fitting, the circular arc-shaped corner 521 slides on the inner wall surface of the first recess 63, under the guiding action of the first concave part 63, the circular arc corner 521 slides from the upper end of the first concave part 63 to the lower end of the first concave part 63, in the process, the cutting knife 50 rotates around the rod member 70 along the first direction, after rotating 90 degrees, the cutting edge 510 of the knife edge part 51 is positioned above the knife slot 410 and the cutting edge 510 faces the insertion end 411 of the cartridge body 41, the base part 52 of the cutting knife 50 falls into the second concave part 64, at this time, the main body part 61 of the push knife member 60 pushes the base part 52 of the cutting knife 50 forward, the cutting blade 50 is moved forward, and the cutting blade 50 moves forward so that the rod member 70 is located at the first end 531 to the second end 532 of the through slot 53. When the rod 70 is moved from the first end 531 to the second end 532 of the through slot 53, the main body 61 of the push blade 60 abuts against the base 52 of the cutting blade 50 and the stop block 421 of the pusher 42, and the additional part 62 of the push blade 60 also abuts against the pusher 42, at this time, the main body 61 of the push blade 60 continues to push the base 52 of the cutting blade 50 and the stop block 421 of the pusher 42 forward, the additional part 62 pushes the pusher 42 forward, the pusher 42 and the cutting blade 50 move forward at the same time, and the cutting edge 510 of the blade part 51 cuts tissue in the process of advancing forward. When the cutting knife 50 moves from the end 412 of the cartridge body 41 to the insertion end 411 of the cartridge body 41, the cutting of the tissue is completed. Due to the friction between the pusher 42 and the cartridge body 41, if the pusher 42 needs to be moved, a sufficient force needs to be applied to the pusher 42. After the tissue is cut, the knife pushing element 60 is moved backward, and since the base portion 52 of the cutting knife 50 is located in the second recess 64 of the additional portion 62 of the knife pushing element 60, the additional portion 62 drives the cutting knife 50 to move backward, and during the backward movement of the cutting knife 50, the position of the rod member 70 is returned from the second end 532 to the first end 531 of the through slot 53, that is, the rod member 70 is returned to the first portion 54 of the through slot 53. The pushing blade 60 continues to move rearward, the pushing blade 60 applies a rearward force to the cutting blade 50, the cutting blade 50 applies a rearward force to the pusher 42, due to the friction between the pusher 42 and the cartridge body 41, this force cannot pull the pusher 42 backwards, and this force causes the rounded corner 521 of the base 52 of the cutting blade 50 to slide from the lower end of the first recess 63 to the upper end of the first recess 63, during this process, the cutting blade 50 is rotated 90 ° about the rod 70 in a second direction, opposite to the first direction, and after the rotation, the cutting edge 510 is located in the groove 423 and faces the bottom of the groove 423, and at this time, the base 52 of the cutting blade 50 is disengaged from the second recess 64 of the attachment portion 62, and the cutting blade 50 and the pusher 42 are not carried rearward by the pushing blade 60 during the further rearward movement, i.e. the cutting blade 50 and the pusher 42 remain at the insertion end 411 of the cartridge body 41.
In summary, when the cartridge module 30 is in the initial (non-use) state, the cutting edge 510 of the knife portion 51 of the cutting knife 50 is located in the groove 423 of the stop block 421 of the pusher 42 and faces the bottom of the groove 423, and the cutting edge 510 of the knife portion 51 is not damaged by foreign objects; when the nail bin assembly 30 is installed in the nail bin seat 10, the cutting edge 510 of the knife edge part 51 rotates to the upper part of the knife slot 410 relative to the limiting block 421; during the travel of the cutting blade 50 within the blade slot 410, the cutting edge 510 of the blade portion 51 cuts tissue; after the tissue is cut, the knife edge part 51 rotates relative to the stopper 421 until the cutting edge 510 of the knife edge part 51 is located in the groove 423 of the stopper 421 and faces the bottom of the groove 423. In the present invention, the cutting edge 510 of the blade section 51 does not damage the patient tissue, nor is it damaged by foreign objects, regardless of whether the cutting blade 50 is in the initial (unused) state or the cut-off state, nor does it damage the doctor when the doctor replaces the magazine.
Although the embodiment of the present invention has been shown and described, it is understood that the above embodiment is illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiment without departing from the scope of the present invention, and all such changes, modifications, substitutions and alterations are intended to be within the scope of the present invention.
