Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a preassembled clip applier of a V-shaped absorbable ligation clip. Background Art

[0002] During clinical surgery, blood vessels, catheters, and other human tubes need to be ligated and closed, which is usually achieved by using a clip applier to fire a ligation clamp. Common surgical clip appliers include a handle with a firing device, a clamp rod, and a clamp jaw. When in use, the clamp jaw is placed around the blood vessel or other tube tissue to be tied, and the clamp jaw is closed to clamp the ligation clamp and achieve the ligation effect. Existing clip appliers are suitable for V-shaped ligation clamps made of non-absorbable POM materials with high elasticity. For V-shaped ligation clamps made of absorbable materials with no elasticity or low elasticity, the ligation clamp may fall off during use, making it unusable. Summary of the Invention

[0003] The present invention aims to solve the problem that existing clip applicators are not suitable for inelastic or slightly elastic absorbable ligation clips and easily cause the ligation clips to fall off, and provides a preassembled clip applicator for a V-shaped absorbable ligation clip.

[0004] The present invention adopts the following technical solution: a pre-assembled clamp applier of a V-shaped absorbable ligation clamp, comprising a clamp arm seat and a first clamp arm and a second clamp arm symmetrically arranged on the clamp arm seat, a clamp groove for placing the ligation clamp is provided on the opposite side of the first clamp arm and the second clamp arm, a ligation clamp fixing groove and a shifting groove are provided on the first clamp arm and the second clamp arm, a barrier is provided between the sides of the shifting groove close to the jaws, a ligation clamp detaching groove is provided next to the ligation clamp fixing groove, the ligation clamp fixing groove is used to fix the corresponding ligation clamp fixing column, and the ligation clamp fixing column slides out of the ligation clamp fixing groove to the ligation clamp detaching groove to realize the ligation clamp detachment, and a ramp is provided in the shifting groove, and the shifting groove provides a sliding space for the corresponding ligation clamp shifting column during the closing process of the clamp applier.

[0005] Furthermore, the front ends of the first clamp arm and the second clamp arm are provided with C-shaped fixing hooks, which are bent toward the clamp arm to form a ligation clip fixing groove, and the rear end of the ligation clip fixing groove is provided with a ligation clip release groove.

[0006] Furthermore, the ramp is arranged obliquely along the clamp arm, the end of the ramp close to the barrier is the highest point of the ramp, and the ramp gradually decreases along the highest point.

[0007] Furthermore, the ligation clip fixing groove and the moving and pulling groove are arched grooves, and the height of the moving and pulling groove is greater than the depth of the ligation clip fixing groove.

[0008] Furthermore, the ligation clip removing groove and the ligation clip fixing groove are arranged in a vertical direction, and the opening radius of the ligation clip removing groove is larger than that of the ligation clip fixing groove.

[0009] Furthermore, an opening and closing jaw is formed between the first clamp arm and the second clamp arm within a range of less than 90°.

[0010] Furthermore, one end of the clamp arm seat is provided with a plug connector for connecting to the clip applier body.

[0011] The present invention has a simple structure, a compact design, and is easy to use. The ligation clip is pre-fixed in the clip applier in a pre-assembled manner for easy use and has good sterilization safety. The design of the clip-detaching groove in the ligation clip enables the ligation clip to detach from the fixing groove. The design of the ramp in the pulling groove is conducive to the smooth detachment of the ligation clip. The present invention is particularly suitable for inelastic or slightly elastic absorbable ligation clips, and solves the problem of ligation clip detachment caused by the unsuitability of the clip applier during clinical surgery.

Implementation Method

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are further described below with reference to the specific drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0025] A preassembled clamp applier for a V-shaped absorbable ligation clamp comprises a clamp arm seat 1 and a first clamp arm 2 and a second clamp arm 3 symmetrically arranged on the clamp arm seat, an opening and closing jaw within a range of less than 90° is formed between the first clamp arm 2 and the second clamp arm 3, a clamp groove 4 for placing the ligation clamp is respectively provided on opposite sides of the first clamp arm 2 and the second clamp arm 3, a front end of the clamp groove 4 is provided with a ligation clamp fixing groove 5 and a ligation clamp detaching groove 13, the ligation clamp fixing groove 5 is provided at the front end of the ligation clamp detaching groove 13 and the two are arranged in a horizontal direction, the end of the ligation clamp fixing groove 5 is bent toward the direction of the ligation clamp detaching groove 13 to form a C-shaped fixing hook 9, a front end of the clamp groove 4 is provided with a moving groove 6, an end of the moving groove 6 close to the jaw position is provided with a barrier 7, and the bottom of the moving groove 6 is inclinedly provided with a ramp 8, the end of the ramp 8 close to the barrier 7 is the highest point of the ramp, and the ramp 8 gradually decreases along the highest point.

[0026] Working principle: The pre-assembled clamp applier of the V-shaped absorbable ligation clamp in the present invention needs to be used in conjunction with a ligation clamp with a fixed column and a moving column when in use. The ligation clamp fixing column 11 is clamped in the ligation clamp fixing groove 5 of the clamp applier, and the first clamp arm 2 and the second clamp arm 3 are closed after clamping the blood vessel to be closed. Due to the setting of the partition, the ligation clamp moving column 12 enters the moving groove 6 accordingly and will not enter the ligation clamp detaching groove 13. As the external force is applied to the first clamp arm 2 and the second clamp arm 3, the ligation clamp moving column 12 moves slowly along the ramp 8 of the moving groove 6. When the ligation clamp moving column 11 moves along the ramp 8 under the action of external force, it pulls the ligation clamp fixing column 11 from the ligation clamp fixing groove 5 to the ligation clamp detaching groove 13 when the ligation clamp is clamped. Then, the ligation clamp is detached from the clamp applier when the jaws are opened. Example

[0027] As shown in the figure, a preassembled clip applier for a V-shaped absorbable ligation clip comprises a clamp arm base 1 and a first clamp arm 2 and a second clamp arm 3 symmetrically arranged on the clamp arm base 1. The first clamp arm 2 and the second clamp arm 3 form an opening and closing jaw within a range of less than 90 degrees. The first clamp arm 2 and the second clamp arm 3 are respectively provided with a clamp groove 4 for placing the ligation clip on the opposite side. The front end of the clamp groove 4 is provided with a ligation clip fixing groove 5, and the rear end of the ligation clip fixing groove 5 is provided with a moving groove 6. The moving groove 6 is provided with a moving groove 6. A spacer 7 is provided toward one end of the jaws, the ligation clip fixing groove 5 is an arched groove, the ligation clip removing groove 6 is also an arched groove, the ligation clip removing groove 13 and the ligation clip fixing groove 5 are arranged in a vertical direction, the ligation clip removing groove 13 is arranged on the outside of the ligation clip fixing groove 5 toward the side opposite to the clamp arm, the opening radius of the ligation clip removing groove 13 is larger than the ligation clip fixing groove 5, the ramp 8 is adapted to the shifting groove 6, and the arched depth of the shifting groove 6 is greater than the depth of the ligation clip fixing groove 13.

[0028] Working principle: The pre-installed clamp applier of the V-shaped absorbable ligation clamp in the present invention needs to be used in conjunction with a ligation clamp with a fixed column and a moving column when in use. The ligation clamp fixing column 11 is clamped in the ligation clamp fixing groove 5, and the first clamp arm 2 and the second clamp arm 3 are closed after clamping the blood vessel to be closed. Due to the setting of the partition 7, the ligation clamp moving column 12 enters the corresponding moving groove 6. Under the action of external force, the ligation clamp moving column 12 is pressed into the bottom of the ramp of the moving groove 6, and the ligation clamp fixing column 11 is tilted out of the ligation clamp fixing groove 5 by the ligation clamp moving column 12 to the ligation clamp detaching groove 13. Since the opening radius of the ligation clamp detaching groove 13 is larger than the ligation clamp fixing groove 5, it can ensure that the ligation clamp fixing column is detached, thereby realizing the detachment of the ligation clamp and the clamp arm.
