    A medical stapler including a ram adapted to push a staple along a passageway from an inlet opening into which staples are fed, to an outlet opening where the staple is ejected and closed about an anvil portion. A manually activated drive mechanism is adapted to move the ram and staple from the inlet to the outlet opening, will leave the ram across the outlet opening to prevent another staple from being fed into the channel if manual activation of the stapler is discontinued before the staple is ejected, and will couple the ram to the drive mechanism when the ram reaches its eject position so that the ram will subsequently be retracted with the drive mechanism. Also the stapler clicks when the ram reaches its eject position to provide both an audible and tactile indication that the staple has been fully closed.

    专利说明:

    The invention relates to medicine, namely, devices for joining fabrics. A device for applying brackets is known, comprising a housing, a staple magazine, a pusher, an anvil, and channels for pushing pushers and brackets, and between the channels have a through opening brace located at the working end of the device. , and a Cl3 pusher mechanism. However, the known device has a complex structure and does not exclude the wedging of the staple in the channel for the passage of the staples. The purpose of the invention is to simplify the design of the device and prevent jamming of the bracket in the channel to move the brackets by eliminating the simultaneous feeding of two brackets into the channel. This goal is achieved in that the device for applying brackets, comprising a housing, a brace magazine, a pusher for bending brackets, an anvil and channels for the passage of the pushers and brackets, and between the channels there is a through-hole brace located at the working end of the device, and a pusher drive for the plunger dL the bend of the brackets is made in the form of a drive element and a slide with an emphasis located in the channel with the ability to interact with each other by means of coupling elements in the working position, the pusher of the lips It is installed in such a way that in the working position it closes the through-hole bracket hole. Figure 1 shows a device for applying brackets, a general perspective view; figure 2 - the same, disassembled, axonometric; in FIG. 3 - the same, top view without a lid and a bracket shop; 4-8 show successive pusher movements. The device for applying brackets comprises a housing 1, a bracket shop 2, a pusher 3, an anvil 4, a channel 5 of the passage of the pusher 3 and a channel 6 of the passage of the brackets 7. Between the channels there is a passage of the bracket 8 located at the operating shaft 9 of the device and a drive of the pusher 3. The pusher 3 for bending the staples 7 is made in the form of a driving element 10 and a slide 11 with a stop arranged in the channel with the ability to interact with each other by means of coupling elements in the working position, and the pusher 3 is installed so that The position overlaps the passage bracket hole 8. The housing 1 is closed by a lid 12. The brace magazine 2 contains the magazine itself (magazine case), the guide 13, the feeder 14 and the spring 15. The drive of the pusher 3 is made in the form of handles 15a mounted on the axles with one end on the housing 1 and the other on the drive element 10. The clutch elements are spring 16 with a rounded protrusion. 17 mounted on the drive element 10, the cam K 18 and the protrusion 19 mounted on the slider 11.. The device works as follows. A package of brackets 7 is placed in the passageway for the staples 7, which is fed by the feeder 14 and the spring 15 to the passage opening 8. The device is guided to the wound edge by the working end 9. By pressing-on the handle 15a, the drive element 10 pb to the side of the working end 9 the device rests on the slider 11, which, as it moves, captures and presses the brace. 7 against the anvil 4, giving it a 0-o 6 different shape and firmly connecting the edge of the wound. . When the drive element 10 moves, its spring 16 with its rounded protrusion 17 goes over the cam 18. If for some reason the bracket did not bend and the handles 15 stopped working, the drive element returns to its original position and the slider 11 remains in place, blocking the staple hole 8 and thus not allowing the next staple to flow through this opening into the passageway for the staples, which prevents the staples from being jammed. If the stapler 7 is completely and correctly bent on the anvil, then the drive element 10 and the slider 11 of the pusher 3 move in the direction of the working end 9 of the device for such a distance that the spring 15 with its rounded protrusion 17 bypasses the cam 18 in a clockwise direction and during reverse movement the rounded protrusion 17 captures the slider 11 behind the protrusion 19 located on it and returns it to its original position. This embodiment of the device provides increased reliability by eliminating jamming of the brackets in the channel.
