Description

The gas channel 8 communicates through the tubular needle 3 with the balloon 2. In addition, the power mechanism includes a reciprocating piston 9 with a spring 10 interacting with the piston 4, the power piston 11 with the rod, which is a shaft 12 the protrusion 13 at the end and which is in the air ep & cop At the same time, in the body of the power unit, the jet 14 is placed with the inlet channel 13 and the bypass channel 16, as well as the drain mechanism with the control handle 17, driver 18 and spring 19, the tool contains a magazine 20 for brackets, which is fixed to the tip with a screw 21c 23 boxes, while the protrusion 13 of the shaft 12: interacts through the opening 24 with the pusher 25 of the magazine. The tip 23 is mounted in the housing 1 with the possibility of rotation around the longitudinal axis of the tool and is kept from longitudinal displacement by the nut 26. The magazine 20, besides the pusher 25, includes the housing 27 with guides for brackets 28, grooves 29 and 30, an emphasis 31 for bending the brackets and clips for placing staples in the form; .Non carrying belt 32 with transverse bands. Const |) ukdi tip j23 and shaft 12 with protrusions-13 provides vrashenne shop 20 around / longitudinal axis relative to the housing 1,, Tool works as follows, - - .. Store 20 proximal part:. Lead to tip 23 under the bracket 21 and join the pusher 5 leading element. Then finally fix the magazine on the tip of the wines, volume 22. The movable connection of the tip 23 ci case1 provides the power of the rotation of the magazine around: the longitudinal axis of the tool that allows. It is not possible to bring the tool into the work tool; , stitching the field, for righteousness, an action tool is pressed on the handle 17, which first: the striker 18 is retracted from the piston flange 4, overcoming the compression force of the spring 19, As the handle 17 is further moved, the striker 18 is released from the contact; the action of the spring .19 strikes the flange of the piston 4. Under the action of the impact, the piston 4 mixes along the longitudinal axis of the housing, compressing the spring 6 "As a result of the movement of the piston 4, the slide 7 opens the outlet opening of the channel 8, and the gas from the cylinder 2 ystrepivsh etc is through channel, then through the channels 5 and 15 to the piston 11. Under the action of gas pressure, the piston 11 moves towards the distal end of the magazine, compressing the spring 33. The excess pressure of the gas formed under the piston 11 through the channel 16. aspires to the prefix 9 and. brings it into action. As a result of the movement, the piston 9 acts on the piston 4, returning | his to the starting position. And in this position, the plug 7 blocks the access of gas to the force. mu piston 11 | which begins to move to its original position under the action of: a previously compressed spring 33,. Remasking under; the gas of the piston 11 is transmitted through the shaft 12 and the protrusion 13 to the pusher 25 of the magazine. As a result, the pusher 25 moves the belt 32 with brackets during the forward stroke of the driving element, feeds the bracket from the belt to the stitched opraiiy and bends the bracket on the stop 31. During the reverse stroke lead) element of the pusher returns to IP. the sliding position, slipping on the tape, which is locked to it with the latch 34. Thus, the design of the tool provides a comfortable fit. . it to the stitched organs, which expands the field of application of the tool, which makes it functionally effective. ness .. Formula - .-. , ... V 1 A surgical instrument for applying staples, comprising a housing, a force mechanism, a staple shop and a leading element, characterized in that, with the aim of increasing the convenience of pointers to stitching. to the bodies, a tip is mounted on the body so that it can rotate around the longitudinal axis of the tool; . : 2 Instrument on n, 1, about tl and h and Yu-. and by the fact that the leading elemeit vyopnen B.vide shaft with a protrusion on the bridge, the ri-itC shop and the leading element set | with the possibility of rotation of the tip tip. . .
