It will be appreciated that a plastic sealing cap is provided at the entrance of the biopsy channel of the endoscope, which cap is provided with openings into which the insertion tube 4 and the forceps head 6 can be inserted. The biopsy forceps 1 is used for being matched with an endoscope, the scale mark 9 closest to the forceps head 6 in the scale marks 9 is a first scale mark, and the distance between the first scale mark and the forceps head 6 is equal to the distance between the biopsy duct inlet and the biopsy duct outlet of the endoscope, namely the distance between the plastic sealing cap of the endoscope and the biopsy duct outlet. The outer diameter of the convex ring 8 is larger than the diameter of the opening of the plastic sealing cap of the endoscope.
When the biopsy forceps 1 is used, the forceps head 6 and the insertion tube 4 of the biopsy forceps 1 are inserted from the biopsy hole entrance of the endoscope, the convex ring 8 is blocked by the sealing cap at the biopsy hole entrance and slides on the insertion tube 4, when the forceps head 6 moves to the biopsy hole exit in the endoscope biopsy hole, the convex ring 8 slides to the positions of the scale marks 9 along the insertion tube 4 and continues to extend into the biopsy hole 1, the convex ring 8 starts to slide on the scale marks 9 and rubs with the scale marks 9 to increase the resistance of the biopsy forceps 1 continuing to extend and generate vibration hand feeling, at the moment, medical staff can know that the forceps head 6 starts to extend from the endoscope biopsy hole exit according to the resistance and continue to apply force to insert into the biopsy forceps 1, the medical staff can feel the vibration hand feeling generated by the matching of the scale marks 9 and the convex ring 8, the medical staff can control the length of the biopsy forceps 1 extending from the biopsy hole exit according to the vibration hand feeling, thereby avoiding injuring the normal tissues of the patient by mistake.
Specifically, the plurality of scale marks 9 are a plurality of annular scale marks 9 protruding on the outer wall surface of the insertion tube 4.
In order to facilitate the medical staff to know the extending length of the biopsy forceps 1 better according to the vibration, the plurality of scale marks 9 are arranged at equal intervals along the length direction of the insertion tube 4.
In order to effectively increase the vibration hand feeling and reduce the resistance to the insertion of the biopsy forceps 1, the center of the convex ring 8 is provided with a through hole for the insertion tube 4 to pass through, and the inner wall surface of the through hole is provided with a resistance piece for increasing the passing resistance of the scale marks 9 when the scale marks 9 pass through the through hole.
As shown in fig. 3, in one embodiment, the resistance member is an arc-shaped protrusion 10 provided on the inner wall surface of the through-hole.
At the bulge loop 8 along scale mark 9 in-process that slides, when arc arch 10 removed to a scale mark 9 position department, produced the resistance with scale mark 9 and rubbed and pass through scale mark 9, get into in the clearance between two scale marks 9, at this in-process, arc arch 10 and scale mark 9 produce the impact vibration effect once, at the bulge loop 8 in-process that slides in succession, arc arch 10 and scale mark 9 impact in succession and produce the continuous vibration effect.
In another embodiment, as shown in fig. 4, the resistance member is an annular projection 11 provided on the inner wall surface of the through-hole.
In the process that the convex ring 8 slides along the scale marks 9, when the annular bulge 11 moves to the position of one scale mark 9, the annular bulge and the scale marks 9 generate resistance and rub to pass through the scale marks 9 and enter a gap between the two scale marks 9, in the process, the annular bulge 11 and the scale marks 9 generate a one-time impact vibration effect, and in the process that the convex ring 8 continuously slides, the annular bulge 11 and the scale marks 9 continuously impact to generate a continuous vibration effect.
As shown in fig. 5 and 6, in another embodiment, the resistance element is an elastic ball element 13 disposed on the protruding ring 8, the elastic ball element 13 includes a ball 14, a spring 15 and a plug 16, a mounting hole 12 transversely penetrating the side wall of the protruding ring 8 is disposed on the side wall of the protruding ring 8, a first end of the mounting hole 12 is communicated with the through hole, a second end of the mounting hole 12 extends to the outer wall surface of the protruding ring 8, an aperture of a first end of the mounting hole 12 is smaller than a diameter of the ball 14, and an aperture of a second end of the mounting hole 12 is larger than a diameter of the ball 14.
The ball 14 partially extends from the first end of the mounting hole 12 to the through hole, the plug 16 is detachably disposed at the second end of the mounting hole 12, and the spring 15 is compressed between the ball 14 and the plug 16.
In the biopsy forceps 1 convenient to operate and control according to the present invention, the first end of the mounting hole 12 is provided with a stopping portion for stopping the ball 14 from extending out of the first end of the mounting hole 12, and the plug 16 is in threaded connection with the second end of the mounting hole 12.
When the elastic ball assembly 13 is installed, the ball 14 is now placed into the mounting hole 12 from the second end of the mounting hole 12, then the spring 15 is placed into the mounting hole 12, and finally the plug 16 is screwed to the second end of the mounting hole 12, so that the spring 15 is compressed and pushes the ball 14 partially into the through hole.
During the process that the convex ring 8 slides along the scale marks 9, when the ball body 14 moves to the position of one scale mark 9, the ball body 14 generates resistance with the scale marks 9 and rubs through the scale marks 9, the ball body 14 contracts towards the inside of the mounting hole 12, when the ball body 14 moves to the gap between two scale marks 9, the ball body 14 extends into the through hole under the action of the elastic restoring force of the spring 15, during the process, the ball body 14 and the scale marks 9 generate a primary impact vibration effect, during the continuous sliding process of the convex ring 8, the ball body 14 and the scale marks 9 continuously impact to generate a continuous vibration effect, and during the continuous sliding process of the convex ring 8, the ball body 14 can be retracted into the mounting hole 12 when being extruded by the scale marks 9, so that the resistance to the insertion of the insertion pipe 4 is reduced.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
