Description

Nail bin with tiger claw

Technical Field

The utility model relates to an anastomat device field especially relates to a take nail storehouse of wall tiger's claw.

Background

The anastomat is the first stapler in the world and is used for gastrointestinal anastomosis for nearly a century, and the tube-type anastomat is not widely used for gastrointestinal surgery until 1978. Generally, the anastomat is divided into a disposable anastomat or a multi-use anastomat, an imported anastomat or a domestic anastomat; the current anastomat has the following problems in the using process:

1. the tissue is easy to be extruded too tightly in the surgical suture process, so that the inner mucosa is damaged;

2. in the surgical suture process, the tiger claw part has more invalid parts, and suture dead points are easy to generate during suture.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a nail bin with a tiger claw, which ensures that the anastomat is not easy to cause damage to the inner mucosa in the operation process.

The technical scheme of the utility model as follows:

a nail bin with a tiger claw comprises a nail bin body; the nail bin body comprises a lower shell and an upper shell, and the upper shell and the lower shell are hinged; the front end of the lower shell is a gecko claw part, and a gecko claw far-end boss is arranged at the end part of the gecko claw part. The gecko claw design can ensure that tissues needing to be sutured have stronger locking force, and the small boss at the far end of the assembly of the gecko claw effectively protects the sutured tissues from being excessively squeezed.

One side of the boss at the far end of the gecko claw is continuous with the plane of the lower shell, and the other side of the boss is continuous with the inclined section of the gecko claw.

At least two drainage grooves are uniformly distributed on the inclined section of the jaw part of the gecko.

And arc transition parts are arranged on two sides of the boss at the far end of the tiger claw.

One side of the far-end boss of the gecko claw, which is connected with the plane, is inclined.

The length from the starting position to the ending position of the gecko claw part is 4.6mm-4.8 mm.

The utility model has the advantages that: 1. when the tiger claw at the far end is closed, the closing is tight, and the tissues have certain gaps to avoid being excessively squeezed;

2. the invalid space at the front end of the tiger claw is reduced, so that the valid space is increased during sewing, the sewing effect is increased, and the sewing dead point is reduced.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Wherein: FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the structure of the drainage groove of the present invention;

in the drawing, 2 is a lower shell, 4 is a gecko claw part, 5 is a far end, 6 is a gecko claw far end boss, 7 is a plane, 8 is an inclined section, 9 is a drainage groove, 10 is an arc transition part, 11 is a starting position, and 12 is an ending position.

Detailed Description

Referring to fig. 1-2, a nail bin with a tiger claw comprises a nail bin body; the nail bin body comprises a lower shell 2 and an upper shell, and the upper shell and the lower shell are hinged; the front end of the lower shell is a gecko claw part 4, and the end part 5 of the gecko claw part is provided with a gecko claw far-end boss 6. The gecko claw design can ensure that tissues needing to be sutured have stronger locking force, and the small boss at the far end of the assembly of the gecko claw effectively protects the sutured tissues from being excessively squeezed. The lug boss is designed at the far end, so that when the nail bin works, a gap exists between the lower shell and the upper shell at the closed position of the far end, and the gap is matched with the gap at the initial position of the upper shell and the lower shell for use, so that tissues are prevented from being excessively squeezed. The length of the gecko claw is designed to be shorter, so that the effective length of the gecko claw is increased, and the suturing effect is better.

One side of the boss at the far end of the gecko claw is continuous with the plane 7 of the lower shell, and the other side of the boss is continuous with the inclined section 8 of the gecko claw. The other end of the far-end boss is continuous with the inclined section, so that the inclined section can provide a supporting force for the inclined section, the strength of the inclined section is enhanced, and the inclined section is not easy to damage when the upper shell and the lower shell are meshed or in the transportation process.

At least two drainage grooves 9 are uniformly distributed on the inclined part of the jaw part of the gecko. The drainage groove is arranged to facilitate the outflow of the tissue fluid.

Arc transition parts 10 are arranged on two sides of a boss at the far end of the tiger claw. The arc transition part is adopted, so that the stress is more uniform, and the result is more reasonable.

One side of the far-end boss of the gecko claw, which is connected with the plane, is inclined. The support effect is better by adopting the inclination result.

The length H from the starting position 11 to the ending position 12 of the gecko claw part is 4.6mm-4.8 mm. Compared with the prior art, the length from the starting position to the ending position is shorter, so that the effective space during sewing is greatly increased, and the sewing effect is better.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
