And this scheme the front end of clamping piece is equipped with the barb structure, can hook the one side of defect mucosa with the barb structure on one side of hemostatic clamp, then to the another side pulling mucosa, reduces the opening of defect mucosa, then the mucosa is hooked to the another side of reuse hemostatic clamp, slowly releases hemostatic clamp then, and the wound surface is closed in the clamp, has increased the power of grabbing to the tissue simultaneously.
Example 2
The difference between this embodiment and embodiment 1 is that two sides of the middle position of the two clamping pieces 1a and 1b are provided with alligator teeth 12, as shown in fig. 12, wherein the number of the clamping pieces is variable, including the tooth shape, the alligator teeth protrude out of the edge of the clamping pieces, and the alligator teeth of the two clamping pieces are in cross fit, so that the closing gap is reduced, the mucosal tissue can be clamped and closed more favorably, and the hemostatic clamp can be prevented from slipping from the mucosal tissue due to normal peristalsis of the.
In clinical use, as shown in fig. 2, the clamping pieces are driven by the driving piece 5 to open through the lateral force of the double sliding grooves and rotate around the fixed shaft 6, and as shown in fig. 3, the clamping pieces are driven by the driving piece 5 to close through the lateral force of the double sliding grooves and rotate around the fixed shaft 6
As shown in fig. 4, the clip rotates around a fixed shaft 6 shown by a dotted line and is closed, and the tail of the clip enters the space avoiding area of the holder. In fig. 4, the side view shows that the barb or hook 7 at the tail of the clip does not enter the groove 8 of the clip seat and is not locked.
As shown in FIG. 6, the clip is not axially displaced in the rotating hole 10, and can be pushed forward by the driving plate 5 to drive the movable shaft 4 to displace in the clip sliding slot to generate the lateral movement of the clip, so that the clip can rotate to reopen and close the clip
As shown in figure 7, under the action of the driving plate 5 exerting the pulling force again, the clamping piece moves backwards to generate the pulling force to enable the clamping piece to rotate the hole 10 (the non-full circle hole elastically deforms to cross the fixed shaft 6 to enter the next hole or groove, and then axial displacement occurs, the hook or barb at the tail part of the clamping piece and the boss 7 elastically deform to cross the clamping seat guide groove to enter the clamping point 8 to form axial locking, and the clamping piece can not be opened any more.)
As shown in fig. 8 and 9, the clip boss or barb 7 has entered the clip seat recess 8 to a locked state where the clip can no longer be opened.
As shown in figure 10, the driving plate 5 is pulled again, and the non-axial stress based on the breakpoint can generate deflection force to cause lateral force to break the driving plate weak point 9, so that the clip assembly stops on the human body.
When the hemostatic forceps are used, a patient enters a diseased position through an endoscope channel, the slide block is pushed forward to open the clamping piece, the handle is rotated to adjust the included angle between the clamp and the diseased position, and then the slide block is pulled backward to accurately clamp the target diseased position to achieve the hemostatic purpose.
The present invention provides a double-sliding groove self-locking hemostatic clamp, and the method and the way for implementing the technical solution are many, the above description is only the preferred embodiment of the present invention, it should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
