Description

Absorbable polymer hemostatic clamp

Technical Field

The utility model relates to a medical consumptive material technical field of peritoneoscope minimal access surgery, concretely relates to can absorb polymer hemostatic clamp.

Background

The laparoscopic surgery is a minimally invasive surgery, compared with the traditional surgery, a laparoscopic surgeon cannot contact the surgical site, blood vessel hemostasis is particularly important, and a hemostatic clamp is generally adopted to clamp and close a ruptured blood vessel clinically. The hemostatic clamp which is most widely used in the market at present is of a V-shaped structure, and hooks at the locking position of the V-shaped clamp are easy to hook human tissues in the operation process, so that the hemostatic clamp is difficult to clamp. Therefore, it is highly desirable to develop an absorbable polymer hemostatic clamp by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art, and providing an absorbable polymer hemostatic clamp which has simple and exquisite structure and firm structure.

In order to achieve the purpose of the utility model, the utility model provides a technical scheme as follows: the utility model provides an can absorb polymer hemostatic clamp, this hemostatic clamp includes that outer clamp and inlayer press from both sides, outer clamp and inlayer press from both sides and are "U" type open structure, outer clamp and inlayer press from both sides and all are equipped with the antiskid and take off the joint, the antiskid is taken off the joint including setting up in the inboard planar draw-in groove of outer clamp and set up in on the inlayer presss from both sides the outside plane with the gib block of draw-in groove looks adaptation, the draw-in groove is mortise type wedge draw-in groove, the gib block is mortise type wedge gib block, the draw-in groove is wedge mortise type with the gib block and is connected, an inlayer presss from both sides a tip and is provided with buckle spare, outer clamp one end inboard is provided with the recess with buckle spare adaptation connection, and hemostatic clamp closes the back, and the buckle spare of inlayer.

Preferably, the angle of the wedge-shaped structure of the conducting bar is in the range of 15-75 °.

Preferably, the outer width of the inner clip after closing is equal to the inner width of the outer clip.

Preferably, the length of the conducting bar is smaller than or equal to the length of the clamping groove.

Based on the technical scheme, compared with the prior art, the utility model have following technical advantage:

the utility model discloses simple structure is exquisite, the sound construction, utilize buckle spare and recess cooperation, utilize outer clamp and inlayer to press from both sides and be "U" type open structure, avoided colluding the problem of human tissue when the operation is used, hemostatic clamp presss from both sides closed effectually, after hemostatic clamp presss from both sides closed, buckle spare and the recess of outer clamp one end inboard of an end of inlayer clamp pass through block fixed connection, fixed effect is better, avoided hemostatic clamp slippage in the blood vessel, be favorable to the clamp of human internal tubulose tissue or other intracavity tissues, the security is higher; the outer clamp all is equipped with the antiskid on pressing from both sides and the inlayer clamp and takes off the joint, and the antiskid is taken off the joint including setting up in the outer inboard planar draw-in groove that presss from both sides and setting up on the inlayer presss from both sides the outside plane with the conducting bar of draw-in groove looks adaptation, and the conducting bar is mortise-tenon formula wedge-shaped conducting bar, and the draw-in groove is wedge mortise-tenon formula with the conducting bar and is connected, utilizes the mutually supporting of conducting bar and draw-in groove to play the guide function in the axial, radially.
