Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1-6, the present embodiment discloses a reclosable closure clip, comprising:

the sleeve 1 is fixed with a baffle plate 101 at the head part, a baffle groove 102 is formed between the outer peripheral wall of the baffle plate 101 and the inner peripheral wall of the sleeve 1, the middle parts of the inner groove surfaces of the two baffle grooves 102 are outwards protruded to form a peak 1021, and the two sides of the peak 1021 are formed with valleys 1022, thereby forming a W-shaped or M-shaped groove surface.

The closing clamp comprises a closing clamp body and a clamping piece, wherein the closing clamp body comprises two clamping pieces 2 which can be manipulated to get close to or away from each other, so that the closing clamp body can be opened or closed, the inner side surfaces of the two clamping pieces 2 are respectively provided with a recess 202 to form a protrusion 203 on the outer side surface, and the structural strength of the clamping pieces 2 is improved; the head parts of the clamping pieces 2 are provided with clamping teeth 204, and the clamping teeth 204 on the two clamping pieces 2 are meshed and used for clamping living tissues; the tail part of the clamping piece 2 penetrates through the blocking groove 102, because the sections of the clamping piece 2 in the length direction and the width direction are both arc-shaped, two ends of the clamping piece 2 in the width direction are positioned in the valleys 1022, and the peaks 1021 in the blocking groove 102 are positioned in the depressions 202 of the clamping piece 2, so that the shape of the blocking groove 102 is more fit with the clamping piece 2; the tail part of the clamping piece 2 is connected with a pull rod 4 through a movable connecting piece 3, the movable connecting piece 3 is connected with the clamping piece 2 in an initial state, and when the pull rod 4 is pulled backwards, the movable connecting piece 3 gradually deforms until the movable connecting piece is separated from the closing clamp body and the sleeve 1 are locked relatively; the middle part of the clamping piece 2 is provided with a first step surface 201 which is abutted against the baffle plate 101.

The fixing sleeve 5 and the pull rod 4 penetrate through the fixing sleeve 5 and can slide in the fixing sleeve 5, the fixing sleeve 5 is clamped and arranged at the tail of the sleeve 1, a clamping sheet 103 is arranged at the tail of the sleeve 1, an annular clamping groove 502 is formed in the outer peripheral wall of the fixing sleeve 5, when the clamping sheet 103 is bent and clamped in the clamping groove 502, the fixing sleeve 5 is clamped with the sleeve 1, and when the clamping sheet 103 is gradually restored to a straight state, the sleeve 1 is gradually separated from the fixing sleeve 5; the head of the fixing sleeve 5 is provided with a second step surface 501 used for being abutted to the movable connecting piece 3, the rear end surface of the movable connecting piece 3 and the second step surface 501 are planes and can be completely attached to each other, the two planes are abutted without causing a clamping phenomenon, as shown in fig. 4, after the closing clamp body clamps the target human tissue, an operator pulls the pull rod 4 backwards, and before the first step surface 201 is abutted to the baffle 101, the second step surface 501 can be abutted to the movable connecting piece 3, so that a resistance signal is provided for the operator to feed back a signal to the operator in advance (namely, the release and the separation of the clamped human tissue closing clamp body can be completed only when the pulling force needs to be further increased). Because the head of the fixed sleeve 5 is provided with the second step surface 501 used for being abutted against the movable connecting piece 3, the rear end surface of the movable connecting piece 3 and the second step surface 501 are planes, and the two can be completely attached to each other, and the matching of the two is earlier than the abutting of the first step surface 201 and the separation blade 101, the situation that the closing clamp body for clamping the human tissue cannot generate release failure is avoided, and the product reliability of the closing clamp of the embodiment is guaranteed.

The working principle is as follows:

firstly, a closed clamp body in a closed state is sent into a human body through an endoscope channel, after the closed clamp body reaches a diseased part, a pull rod 4 is pushed forwards, two clamping pieces 2 are far away from each other so as to be opened to clamp diseased or wound tissues, at the moment, the closed clamp body is in an open state, then the pull rod 4 is pulled backwards, the closed clamp body is gradually closed to clamp the living tissues, in the process of pulling the pull rod 4 backwards, a movable connecting piece 3 synchronously moves backwards, when the movable connecting piece is abutted against a second step surface 501 of a fixed sleeve 5, a signal can be fed back to an operator, namely, the clamping of the living tissues is finished, the operator can confirm whether the clamping position is proper, if the movable connecting piece is not proper, the pull rod 4 is pushed forwards to repeat the operation, if the clamping position is proper, the pull rod 4 is continuously pulled backwards, the movable connecting piece 3 gradually deforms, and is separated from the closed clamp body, so that the closed clamp body and a sleeve 1 are relatively locked, the sleeve 1 is separated from the fixed sleeve 5, and the movable connecting piece 3 and the fixed sleeve 5 are removed together with the endoscope.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
