Drawings

Fig. 1 is a schematic structural view of the open state of the present invention;

fig. 2 is a schematic structural view of the closed state of the present invention;

FIG. 3 is a schematic view of the present invention as applied to a cartridge;

in the figure: the tissue clip comprises an upper half clip 15, a lower half clip 16, a connecting part 17, a guide upright post 18, a hollow through hole 19, a hook body 20, a clamping tooth 21, a tissue clip 102 and a guide strip 113.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-3, a tissue clip capable of being stably pushed, the tissue clip 102 includes an upper clip 15 and a lower clip 16, the end of the upper clip 15 is connected with the end of the lower clip 16 through a connecting portion 17, and at least one guiding column 18 fixedly connected to the upper clip 15, the lower clip 16 and/or the connecting portion 17, wherein one end of the guiding column 18 protrudes out of the side surface of the upper clip 15, the lower clip 16 or the connecting portion 17.

When the tissue clip is used, the plurality of tissue clips 102 are sequentially preloaded into the tissue clip accommodating cavities of the cartridge clip shell and then sequentially clamped by pushing the feed rod. The end of the feeding rod close to the tissue clamp 102 is also fixedly connected with a guide strip 113, one end of the guide strip 113 extends into the tissue clamp accommodating cavity, and the tissue clamp 102 comprises a guide upright post 18, and the end part of the guide upright post 18 protrudes out of the side surface of the upper half clamp 15, the lower half clamp 16 or the connecting part 17, so that the end part of the guide upright post 18 is pressed on the guide strip 113 when in use, and the tissue clamp 102 moves along the guide strip 113 in the feeding process. The guide strips 113 may be steel wires and may also ensure stability and consistency of the position of the tissue clip 102 within the clip housing 101.

As shown in fig. 1 and 2, two ends of the guiding column 18 respectively protrude out of two sides of the upper half-clamp 15, the lower half-clamp 16 or the connecting portion 17.

As shown in fig. 1, the guide post 18 is connected to the connecting portion 17. Thus, the guide posts 18 can have a small displacement distance when the upper half clamp 15 and the lower half clamp 16 rotate relatively to each other for clamping.

Preferably, said guide uprights 18 are provided in two and are connected respectively to the connecting portion 17 at one end close to the upper half-grip 15 and at one end close to the lower half-grip 16. I.e. there is a certain clearance between the two guide uprights 18, preventing interference problems during use.

Further preferably, the axes of the two guide posts 18 are parallel to each other.

As shown in fig. 1, the connecting portion 17 is further provided with a hollow through hole 19 penetrating through the connecting portion 17. Because the connecting portion 17 can deform when the upper half clamp 15 and the lower half clamp 16 rotate relatively, a hollow through hole 19 is formed to reserve a space for the connecting portion 17 to deform, so that the tissue clamp 102 can be clamped conveniently.

Preferably, the hollow through hole 19 is circular arc-shaped, and the width of the hollow through hole 19 gradually decreases from the middle to the two ends. This shape is more preferable because the amount of deformation is larger at the middle of the connecting portion 17 and is smaller at both sides during rotation.

As shown in fig. 1, an end of the upper half clamp 15 away from the connecting portion 17 is provided with an inwardly bent hook 20.

As shown in fig. 1, a plurality of holding teeth 21 are provided on the inner surface of each of the upper half-clip 15 and the lower half-clip 16, and the holding teeth 21 protrude from the inner surface of each of the upper half-clip 15 and the lower half-clip 16. The protruding gripping teeth 21 ensure that the tissue clip 102 has a better gripping force on the tissue.

Preferably, the clamping teeth 21 arranged on the inner surfaces of the upper half clamp 15 and the lower half clamp 16 are arranged in two rows, the clamping teeth 21 between the two rows are arranged in a staggered manner, and the distance between every two adjacent clamping teeth 21 in the same row is equal. The distribution mode can ensure that the distribution of the clamping force is more scientific and reasonable.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms upper half-clip 15, lower half-clip 16, connecting portion 17, guide post 18, hollowed-out through hole 19, hook 20, gripping tooth 21, tissue clip 102, guide strip 113, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any one of the additional limitations of the present invention.
