The working principle and the working process are as follows:
1. as shown in FIG. 1, the two sets of opposing jaws are in an open position
Promote pull rod 6 and move towards the direction that is close to clip subassembly 1, pull rod 6 produces thrust to locking piece 5 through slip round pin axle 17, and locking piece 5 produces thrust to clip base 4 through removal round pin axle 16, and at this moment clip base 4 stretches out outside clip support 2 under the effect of thrust. Because the clip component 1 is rotatably connected with the clip base 4 through the rotating pin 3, the tail part of the clip component 1 is driven by the clip base 4 to extend out of the clip support 2, and under the elastic action of the high-elastic steel wire 15, the first clip 11 and the second clip 12, and the third clip 13 and the fourth clip 14 are in an open state. When the lower limiting surface 43 of the clip base abuts against the lower limiting surface 22 of the clip support, the first clip 11 and the second clip 12, and the third clip 13 and the fourth clip 14 are in the maximum-amplitude opening state;
2. as shown in FIG. 2, the two sets of opposite jaws are in a closed state
Pulling pull rod 6 and moving towards the direction of keeping away from clamping piece subassembly 1, pull rod 6 produces the pulling force to locking piece 5 through slip round pin axle 17, and locking piece 5 produces the pulling force to clamping piece base 4 through removal round pin axle 16, and clamping piece base 4 will contract in clamping piece support 2 under the pulling force effect at this moment. Because the clamping piece assembly 1 is rotatably connected with the clamping piece base 4 through the rotating pin shaft 3, the tail part of the clamping piece assembly 1 is driven by the clamping piece base 4 to be contracted in the clamping piece bracket 2, so that the first clamping piece 11 moves towards the direction close to the second clamping piece 12, and the third clamping piece 13 moves towards the direction close to the fourth clamping piece 14. When the upper limiting surface 42 of the clip base is abutted against the upper limiting surface 21 of the clip bracket, the first clip 11 and the second clip 12, and the third clip 13 and the fourth clip 14 are in a closed state;
3. two sets of opposite clamping pieces are locked in a closed state
The two sets of opposite clamping pieces are in a closed state, the tension on the pull rod 6 is increased, the locking piece 5 can move under the tension, but the two sets of opposite clamping pieces are closed at the moment, and the moving pin shaft 16 cannot move any more due to the propping of the moving channel 52. When the pulling force increases to a certain extent, the moving pin 16 presses against the moving channel 52, so that the moving channel 52 deforms, causing the moving pin 16 to move from the moving channel 52 to the top of the moving channel and to abut against the limit point 53. Meanwhile, the pawl 54 of the locking member 5 is pressed by the annular boss 23, the pawl 54 approaches to the main body through elastic shape, so that the locking member 5 passes over the annular boss 23, the pawl 54 recovers the shape after passing over the annular boss 23, and springs into the clamping part to be clamped in the clamping part 24, so that the locking member 5 cannot move, the clip base 4 cannot move in the clip support 2, and finally the first clip piece 11 and the second clip piece 12, and the third clip piece 13 and the fourth clip piece 14 are locked in a closed state;
4. as shown in FIG. 8, the clip device is unhooked from the excess instrument
The pulling force on the pull rod 6 is continuously increased, when the pulling force is large enough, the sliding pin 17 extrudes the sliding groove 56, so that the sliding groove 56 deforms, the sliding pin 17 penetrates through the sliding groove 56 to be separated from the locking piece 5, meanwhile, the pull rod 6 drives the positioning piece 8 to move towards the interior of the spring tube 10, the positioning piece 83 deforms due to stress and breaks away from the positioning hole 25 of the clamping piece support 2 and the positioning hole 91 of the spring bush 9, the pull rod 6, the sliding pin 17, the positioning piece 8 and the locking piece 5 are separated, and the spring bush 9 and the clamping piece support 2 are separated. The novel clamp device comprises a clamp piece component 1, a clamp piece support 2, a clamp piece base 4, a locking piece 5, a rotating pin shaft 3 and a moving pin shaft 16 which are left in a patient body, redundant instruments comprise a pull rod 6, a positioning piece 8, a spring bushing 9, a sliding pin shaft 17 and a spring tube 10 which are taken out from the endoscope forceps, and the novel clamp device is unhooked from the redundant instruments.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
