    A staple cartridge and feed means for use with a surgical stapling instrument of the type having an anvil about which a staple is formed during emplacement thereof in the skin or fascia of a patient. The cartridge comprises a body having a vertical staple feeding track adapted to hold a stack of staples and a separate vertical staple forming track with a staple former reciprocable therein by the surgical stapling instrument. The staple forming track and the staple feeding track are in parallel relationship separated by a divider wall. A window, defined by the cartridge body and the divider wall, provides a horizontal path between the staple feeding track and the staple forming track and is so sized as to permit the passage therethrough of a single staple from the bottom of the staple stack. Horizontal feeder means normally prevent passage of the bottommost staple from the stack through the window into the staple driving track. The horizontal feeder means, actuable by the surgical stapling instrument, positively shifts the bottommost staple of the stack from the staple feeding track horizontally through the window to the staple forming track and cooperates with retainer springs to hold a shifted staple in position in the staple forming track to be implanted and formed about the anvil by the staple former.

    专利说明:

    This invention relates to medicine, in particular, to devices for soya denis tissue. A known magazine for brackets, comprising a housing with a bend channel for brackets and a feed channel for brackets, a mechanism for feeding brackets along the feed channel, a mechanism for feeding brackets from the feed channel to the bend channel, and a bending pusher for bending the brackets of the stapler 11. This device is insufficient reliability in operation and complexity of the design. The purpose of the invention is to increase the reliability of the store and its design. This goal is achieved by the fact that in a magazine for scraper boxes containing a housing with a bend channel of brackets and with a feed channel of brackets along the feed channel, a feed mechanism from the feed channel to the bend channel and a bending pusher for bending the brackets on the anvil of a staple device, the feed channel the brackets are separated from the bend channel by the brackets with a window, the window shape and dimensions correspond to the brackets form and sizes, the magazine body is equipped with a window locking mechanism, made in the form of a pair of L-shaped locking springs, a dropping mechanism There is an agglomerate bracket with an anvil of a sewing machine, the dumping mechanism being in the form of a spring frame with legs for resetting the bracket, a mechanism for feeding the brackets along the channel of delivery made in the form of a wave-shaped spring, a mechanism for feeding the brackets through the window, made in the form of a tongue with a pusher and a cam At the end, and above the tongue, a recess is made in the magazine case, in which the bar for bending the tongue is located, and the stack of the bend channel of the brackets has a tooth for braking the bending pushers. In the bar for bending the tongue and in bending. m pusher provided with openings beneath the leading finger crosslinkable present apparatus. In addition, the magazine consists of three parts, predominantly rectangular housings for feeding scobo bend brackets and intermediate. Figure 1 shows a magazine for brackets, a general perspective view; figure 2 - bracket; FIG. 3 shows a surgical stapler with a non-store for brackets; Fig. 4 shows the disassembled store for the cage, axonometric in Fig. 3, section A-A in Fig. 1; n fig.b-- the bend diagram of the bracket on the anvil. The magazine 1 for brackets 2 comprises a housing 3 with a channel 4 for bending brackets 2 and with a channel 5 for feeding brackets 2, a mechanism 6 for feeding brackets 2 along a channel 5 for feeding, a mechanism 7 for feeding brackets 2 from channel 5 for feeding into channel 4 for a bend, and a bending pusher 8 to bend brackets 2 on the anvil 9 of the stitching apparatus 10. The channel 5 for feeding brackets 2 is separated from channel 4 by bending brackets 2 by wall 11, with window 12. The shape and dimensions of window 12 correspond to the shape and sizes of bracket 2. Case 3 of magazine 1 is equipped with a locking mechanism 13 window 12, made in the form of L-shaped locking springs, mechanism 1 4 dropping a curved bracket 2 from the anvil 9 of the stapler 10, made in the form of a spring frame 15 with the legs 16 of the relief bracket 2, the mechanism for feeding brackets 2 along the channel 5 for feeding brackets 2, made in the form of a wave spring, the mechanism 7 for feeding brackets 2 through window 12, made in the form of a tongue 17 with a pusher 18 and a cam 19 at the end. A recess 20 is made above the tongue 17 in the magazine body, in which the strip 21 is located to bend the tongue 17, and the wall of the channel 4 of the bend of brackets 2 has a tooth 22 for braking the bending pusher 8. In the strip 21 for folding the tongue 17 and in the bending pusher 8 23 under the leading finger 24 of the stapler 10. Store 1 for brackets 2 consists of three parts {predominantly rectangular housings): case 25 for feeding the staples, case 26 for bending the staples and intermediate case 27. The shop works as follows. The package of brackets 2 under the action of the mechanism 6 (wave spring) is fed to window 12, through which bracket 2 is fed to ka (4 to bend the brackets. Mechanism 13 locking the window prevents the second bracket 2 from being fed. The bending pusher B moves along the magazine 1 under the influence of the finger 24 of the stapler 10, the bracket 2 is fed to the anvil 9 and bent on it in an O-shape, firmly connected to the edge of the fabric. After stitching, the mechanism 14 for dropping the bent bracket clears the magazine from the bent bracket. improves reliability and simplifies the design of the device.
