Description
Technical field
The present invention relates to endoscopic instruments fields, are specifically related to a kind of collet release pincers.
Background technique
With the rapid development of endoscope diagnosis and treatment, corresponding digestive system leads to notch or perforation, mesh because of operation or other reasons
Preceding common scope repair mode is that soft tissue folder closure is repaired, and soft tissue folder enters patient's body by scope, and folder closes wound.
The collet of soft tissue folder has that clip position is undesirable, at this point, collet is already fixed on soft tissue, nothing
Method is taken off, and notch reparation is influenced.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of releases of collet to clamp, collet can be pacified from soft tissue
It removes entirely.
To achieve the above object, the invention adopts the following technical scheme:
A kind of collet release pincers, including following component part:
Collet portion, the collet portion include protective case and the clamping unit that is mounted in protective case, and the protective case is arranged
Outside clamping unit, one end of protective case is clamp end, and the other end is positive stop end；The clamping unit reaches protective case folder
One end outside mouth end is pinching end, and the other end of the clamping unit extend into the inside of protective case；
Pincers portion is discharged, for driving clamping unit to protective case clamp end side when the pinching end clamping of clamping unit
Movement is to open pinching end.
Further, the clamping unit includes tissue clamp arm, and the stretching of the tissue clamp arm is on the outside of protective case clamp end
End constitute pinching end；The clamping unit further includes the mechanism that pulls being connected with tissue clamp arm, described to pull mechanism extruding
In protective case, the position in protective case is extend into for fixing tissue clamp arm.
Further, the mechanism that pulls includes the elastic clip being connected with tissue clamp arm, two elasticity of the elastic clip
The side towards protective case inner wall of clamp arm is respectively equipped with the first elastic component and the second elastic component, the expanding elastic of the elastic clip
So that the first elastic component and the second elastic component are tightly pressed against on protective case inner wall；Relative to each other one of two elastic clamp arm
Side further respectively has the first extrusion and the second extrusion.
Further, the protective case is provided with limit hole and annular clip slot, the bullet at the opposite position of its positive stop end
Property folder one of elastic component when being placed in limit hole, the pinching end closure of the tissue clamp arm.
Further, the protective case is provided with limit hole in its positive stop end, and the elastic component on the elastic clip is placed in limit
When in hole, the pinching end closure of the tissue clamp arm.
It is further preferred that a pinching end of the tissue clamp arm is equipped with V-type lug boss, it is described to organize the another of clamp arm
The concave part of V-type is offered on one pinching end.
Further, the release pincers portion includes release clamp main body, release tong arm and push-pull rod, and two release tong arms are handed over
Fork is arranged and stretches out the front end in release clamp main body, and two crosspoints for discharging tong arm and the release clamp main body are hinged,
The flexible linkage unit of tong arm is connected between release tong arm and the push-pull rod, the push-pull rod is flexible by pushing and pulling the tong arm
Linkage unit controls the folding condition of the release tong arm；The release tong arm, which is clamped and elapsed, to be extend into the limit hole
Elastic component forces elastic component to be pressed back into the inside of protective case, alternatively, the setting position of the annular clip slot to release when described
When putting tong arm and clamping the annular clip slot and/or limit hole, the positive stop end of protective case deformation occurs and force the first elastic component and
Second elastic component is pressed back into the inside of protective case, and the pinching end of the tissue clamp arm opens.
It is further preferred that offering card slot at first extrusion and the second extrusion relative position.
It is further preferred that the inside of the protective case is equipped with the first limiting section, the tissue clamp arm is located at the first limit
The two sides in portion, for preventing clamping unit from falling off out of protective case.
It is further preferred that the release clamp main body is elastic tube；The tong arm stretches linkage unit to be connected to push-and-pull
The tie point of connecting rod on bar, the connecting rod and push-pull rod be slidably arranged in release clamp main body sliding slot in, the connecting rod with release
Put that tong arm is hinged, one end that the push-pull rod reaches outside release clamp main body is connected with pulling ring.
Beneficial effects of the present invention are as follows:
(1) protective case and clamping unit are separate structure, and clamping unit can move in protective case, and release pincers portion pushes
Clamping unit is gradually removed out of protective case, and the subtended angle of the pinching end of clamping unit becomes larger, and pinching end is paid no attention to clamped position
The soft tissue separation thought, i.e., collet is separated with the soft tissue.Doctor is facilitated to do the treatment of a step to soft tissue incision at this.
(2) the first limiting section is set in the inside of protective case, the first limiting section is gag lever post, and two tissue clamp arm are located at limit
The two sides of position bar, can prevent entire clamping unit from falling off out of protective case.The inside of protective case is set in the two sides of clamping unit
Anti- transfer part is set, for preventing clamping unit from relatively rotating in protective case, improves the accuracy of clip position.
(3) the V-type lug boss on the pinching end of tissue clamp arm and the concave part of V-type cooperate, and can increase pinching end
Clamping degree, prevent tissue clamp arm from separating with soft tissue incision.
