Problems solved by technology

In this way, the force on the cartilage sheet near the teeth of the forceps is greater, and the surface of the cartilage is smooth and not level, which will form a squeezing force when clamping one end, which will easily cause the cartilage to slip
[0003] When using the existing cartilage forceps, the suture is inconvenient and affects the suture operation

Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a fine positioning cartilage tweezers includes two clamping parts 1 and two handles 2, and the two clamping parts 1 and the two handles 2 are provided in one-to-one correspondence. One end is fixedly connected to one end of the corresponding handle 2 , the other ends of the two handles 2 are fixedly connected, the clamping part 1 has a suture through hole 3 , and the inner side of the clamping part 1 has an engaging part 4 .

[0037] Specifically, the inner side of the clamping part 1 refers to the opposite surface of the two clamping parts 1 .

[0038] Specifically, the clamping part 1 is in the shape of a strip, the handle 2 is in the shape of a strip, the clamping part 1 and the handle 2 are coplanar and integrally formed by a mould. The other ends of the two handles 2 are welded together.

[0039] Specifically, the width d of the clamping portion 1 is 3mm-5mm. Preferably, the clamping portion 1 has a width d of 3.5 mm.

...

Embodiment 2

[0055] On the basis of Example 1, as Figure 3-Figure 4 As shown, the included angle between the clamping part 1 and the handle 2 is 110-180°.

[0056] Specifically, the clamping part 1 is coplanar with the handle 2, and the angle e between the centerline of the clamping part 1 and the centerline of the handle 2 preferably ranges from 110° to 160°. Preferably, the included angle e is 130°.

Abstract

The invention relates to fine positioning cartilage forceps. The positioning cartilage forceps comprise two clamping parts and two handles; the two clamping parts are arranged correspondingly to the two handles one to one, one end of each clamping part is fixedly connected with one end of the corresponding handle, and the other ends of the two handles are fixedly connected with each other; each clamping part is provided with a sewing through hole, and the inner side of each clamping part is provided with an engaging part. The design of the novel fine positioning cartilage forceps is more reasonable in engineering principle. In an operation process, a cartilage material can be precisely sewed and fixed under direct vision, so that the operation efficiency is improved, and the operation timeis shortened. The engaging parts on the clamping parts ensure that cartilage pieces can be clamped by the cartilage forceps in the whole process and prevented from slipping. Each sewing through holeis provided with two closed ends, each clamping part is still provided with a planar structure, the structural strength is high, the service life is long, and the fine positioning cartilage forceps are unlikely to be damaged and broken. The cartilage forceps are simple and visible, popularization, production in batch and result conversion are easy, and finally, more receivers of rhinoplasty are benefited from the cartilage forceps.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a fine positioning cartilage forceps. Background technique [0002] Adson-Brown forceps, often called cartilage forceps in practice, are the most commonly used operating instruments in rhinoplasty, and are used to hold cartilage. When two cartilage pieces need to be sutured during the operation, if traditional cartilage forceps are used, only the edges of the cartilage pieces can be clamped, and then the cartilage outside the clamping range of the forceps can be sutured. In this way, the force on the cartilage sheet near the teeth of the forceps is greater, and the surface of the cartilage is smooth and uneven, which will form a squeezing force when one end is clamped, which will easily cause the cartilage to slip. [0003] When using the existing cartilage forceps, it is inconvenient to suture, which affects the suture operation. Contents of the invention [0004] The tech...
