Definitions
- the wire buckle is wound around the movable pin shaft, and when the pulling force applied to the wire buckle reaches a predetermined value
- the wire buckle is straightened away from the movable pin; after the wire buckle is separated from the movable pin, the rear of the clip body is fixed in the holder.
- the buckle Connected to the transition cap, when the tension applied to the paws reaches a preset value (the range of the value is 20-30N), the buckle is elastically deformed and straightened, so that the buckle is disengaged from the slot, and the clip and the transition cap are disengaged. ;
- the hemostatic clip according to the present invention is simple and convenient to operate, and can be rotated conveniently according to various angles in the human body. At the same time, when the hemostatic clip is successfully positioned, the manipulation rope can be pulled off, the purpose is Leave the body of the hemostatic clip inside the body.
- Figure 1 is a schematic view of the overall structure of the present invention.
- Figure 2 is a partial enlarged view of the first part of Figure 1.
- the wire buckle is disposed on the movable pin shaft.
- the wire buckle is straightened away from the movable pin shaft; after the wire buckle is separated from the movable pin shaft, the rear of the clip body The part is fixed in the holder.
- the tail ends of the two clamping arms are provided with a hook structure, and the clamping seat is provided with a protrusion adapted to the hook structure, when the two clamping arms are in the locked closed position, the two clips A hook structure at the end of the arm is snapped onto the projection.
- the clamping seat is connected to the transition cap, the fixing cap and the distal spring tube to form an outer sleeve assembly
- the clamping assembly comprises a connecting piece connecting the wire buckle
- the connecting member is provided with elastic claws, and the claws are arranged
- the inner diameter of the fixed cap and the distal spring tube is larger than the maximum outer diameter of the wire buckle, the connecting member and the pawl.
- a spring tube transition member is disposed in the distal spring tube, and the connecting member is coupled to a operating rope, and the spring tube transition member is provided with a through hole for accommodating only the operating rope.
- the shape of the hole in which the clamping arm is provided with the movable pin shaft is a waist-round shape.
- the present invention discloses a hemostatic clip comprising an outer cannula assembly and a clamping assembly located in the outer cannula assembly.
- the outer cannula assembly is sequentially connected to the clamping seat 4, the transition cap 8, and fixed.
- the two clamping arms la, lb are in an open state, and the hemostatic clip can be aligned with the body part that needs to be clamped to stop bleeding.
- the operating rope 14 can be rotated as needed to thereby drive the hemostatic clip body to rotate.
- the operating rope 14 is pulled backward, and the two gripping arms la, lb are along the chute.
- the tracks formed by lc, Id and the fixed pin 2 are retracted while being closed.
- the ends of the chutes lc, Id are provided with bending structures lcl, ldl.
- the tail ends of the two clamping arms are provided with a hook structure lb1
- the clamping seat is provided with a protrusion 4a adapted to the hook structure, when the two clamping arms are in the locked closed position
- the hook structure of the ends of the two clamping arms is snapped onto the protrusions. That is, in this position, the gripping arms la, lb will not open again.
- the chute is a sliding slot with a curvature.
- the hemostatic clip body When in use, the hemostatic clip body is transported to the designated position of the lesion under the auxiliary monitoring of the endoscope, and the conductive plug at the handle is turned on to the high frequency power supply, the slider is retracted, and the clamp head is closed, which can be used as the high frequency cut.
- the present invention provides a hemostatic clip, and there are many ways and means for implementing the technical solution.
- the above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art do not deviate from the present invention.
- On the premise of the inventive concept several modifications and refinements can also be made, and such improvements and refinements should also be considered as protection scope of the present invention.
- the components that are not clear in this embodiment can be implemented by the prior art.
