Insurance stop, safety structure and fit system:
In the jaw closing course, as shown in Figure 22-1 and Figure 22-2, above-mentioned throw-out collar 34 moves ahead under the effect of as shown in figure 19 push broach connecting rod 16, as shown in figure 20, the above-mentioned limit rope 31 that above-mentioned throw-out collar 34 sides are fixed in drive pulls above-mentioned position limiting slide block 33 to move ahead, the above-mentioned indication limited block 32 and the 14 middle above-mentioned ratchet gears 142 of above-mentioned drive as shown in Figure 7 that are positioned on above-mentioned position limiting slide block 33 are meshed, and in the percussion process, can prevent the drive rollback.
When jaw is fully not closed, if unclamping close handles resets, due to above-mentioned indication limited block 32 and above-mentioned drive 14 engagements, make the above-mentioned stroke piece 13 can not rollback in above-mentioned closed clamping plate 11 reseting procedures, above-mentioned indicator wheel 22 stops operating, and above-mentioned sliver 12 is moved with respect to above-mentioned stroke piece 13, return back to initial position, and above-mentioned the first extension spring 124 as described in Figure 6 between above-mentioned stroke piece 13 and above-mentioned sliver 12 is stretched.Close handles again, again drives above-mentioned stroke piece 13 and advances when contacting with above-mentioned stroke piece 13 when above-mentioned sliver 12 action, and the above-mentioned indicator wheel 22 of stall before this just is rotated further till the complete closure of handle.
after closure, handle is being opened fully, as shown in figure 19, above-mentioned sliver 12 drives above-mentioned stroke piece 13 and withdraws under above-mentioned support link 15 and 125 effects of above-mentioned bearing pin, because above-mentioned stroke piece 13 is pressed on the below by above-mentioned lower diving board spring 2181, therefore the above-mentioned sliding axle 133 as shown in Fig. 5-1 of above-mentioned stroke piece 13 slides via above-mentioned stroke piece guide rail 214 lower surfaces of the above-mentioned indication seat 21 as shown in Figure 14-3, when the above-mentioned sliding axle 133 of stroke piece breaks away from above-mentioned stroke piece guide rail 214 lower surfaces, above-mentioned stroke piece 13 bounces back into initial position under the effect of above-mentioned stroke block reset spring 136.
Again press close handles, pull the trigger, as shown in Figure 22-1, above-mentioned sliver 12 drives above-mentioned stroke piece 13, repeat same action, as shown in Figure 22-2, tooth on above-mentioned stroke piece 13 and the tooth on above-mentioned drive 14 are meshed, driving above-mentioned drive 14 continues to turn clockwise, above-mentioned drive 14 further drives above-mentioned indicator wheel 22 and rotates counterclockwise, and then drive above-mentioned indicating dial 23 and rotate counterclockwise, see color lump on the above-mentioned indicating dial 23 acquisition indication information that changes by being fixed in indicating window on apparatus.
Repeatedly press handle three times, complete the percussion stroke, apparatus is closed and locked.
after line cutting stitching instrument is completed and is coincide, carrying out jaw resets, above-mentioned limit rope 31 as shown in figure 20 is loosening, as shown in figure 21, the resilience under above-mentioned reset tension spring 2161 effects of above-mentioned position limiting slide block 33, the tooth that is positioned at above-mentioned indication limited block 32 and above-mentioned drive 14 on above-mentioned position limiting slide block 33 breaks away from, indication component resets under above-mentioned the first torsion spring 225 effects as shown in figure 15 that are positioned at above-mentioned indicator wheel 22 lower ends, above-mentioned indicator wheel 22 drives above-mentioned drive 14 and rotates counterclockwise, the above-mentioned indicator wheel 22 above-mentioned indicating dials 23 of drive clockwise rotate gets back to initial position.
Illustrate, during the apparatus original state, the color in indicating window is white, when jaw is closed, the cooperation of above-mentioned stroke piece 13 and above-mentioned drive 14 drives above-mentioned indicator wheel 22 75 degree rotations occurs, and occurs the fraction green in indicating window, percussion for the first time, in form, green increases, until complete percussion for the third time, is filled by green fully in indicating window, after indicator collet resets, get back to white displays in indicating window.
Above-mentioned reset mode is original state or initial position, namely as Fig. 1, Figure 19 and state shown in Figure 23.As shown in figure 23, reset above-mentioned indicator wheel 22 and above-mentioned closed clamping plate 11 are to original state, and as shown in figure 19, above-mentioned sliver 12 return back to initial position after being moved with respect to above-mentioned stroke piece 13.
Preventing that above-mentioned indicator wheel 22 is rotated in a clockwise direction refers to prevent that above-mentioned indicator wheel 22 is along the rotation of the clockwise directions as shown in Figure 22-2, above-mentioned drive 14 turns clockwise and refers to that the direction of rotation of above-mentioned indicator wheel 22, above-mentioned indicating dial 23 and above-mentioned drive 14 is the direction as shown in Figure 22-2 along the rotation of the clockwise direction as shown in Figure 22-2.
The line cutting stitching instrument that the present invention addresses is sometimes also referred to as similar title, such as linear incision stiching instrument, linear cutting anastomat, open line cutting stitching instrument etc., and what its structure was identical with function all falls within the scope of protection of the present invention.
