The utility model discloses a needle holder, its characterized in that: the needle holder comprises a first clamp arm and a second clamp arm, the first clamp arm is divided into a first clamp handle, a first clamp head and a first connecting portion, the second clamp arm is divided into a second clamp handle, a second clamp head and a second connecting portion, the first connecting portion and the second connecting portion are hinged and fixed through pins, the inner side clamp face of the first clamp head is a convex face, the inner side clamp face of the second clamp head is a concave face, the radian of the convex face is identical to that of the concave face, and the surface of the convex face is provided with insections. The utility model provides a needle holder designs for convex surface and concave surface at needle holder's front end, has improved the power degree that adds of needle holder, when needle holder adds the suture needle, can be along the radian automatic adjustment of needle holder to with needle holder vertically position, save time, save left hand and assist the adjustment.

Description

Needle holder

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a needle holder.

Background

Needle holders are common instruments used in surgical suture operations and are mainly used for clamping needles to suture wounds. Most needles used for suturing in the operation are circular arc-shaped, the front ends of needle holders commonly used at present are all in a plane structure, when the needle holders clamp the needles, the left hands are usually needed to assist in holding the needles vertically, when the left hands of a suturing person need to expose tissues, the right hands are often needed to automatically adjust the suturing needles to the vertical angle through the needle holders, and therefore the suturing needle holder is difficult to grasp, takes time, and can be mastered by a large amount of training.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a needle holder.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a needle holder characterized by: the needle holder comprises a first clamp arm and a second clamp arm, the first clamp arm is divided into a first clamp handle, a first clamp head and a first connecting portion, the second clamp arm is divided into a second clamp handle, a second clamp head and a second connecting portion, the first connecting portion and the second connecting portion are hinged and fixed through pins, the inner side clamp face of the first clamp head is a convex face, the inner side clamp face of the second clamp head is a concave face, the radian of the convex face is identical to that of the concave face, and the surface of the convex face is provided with insections.

Furthermore, the tail end of the first forceps handle is provided with a first handheld ring, the inner side of the first handheld ring is provided with a limiting groove column, and a spring is fixed in the limiting groove column.

Furthermore, a second hand-held ring is arranged at the tail end of the second clamp handle, a limiting column is arranged on the inner side of the second hand-held ring, and the limiting column is clamped into the limiting groove column.

Further, the curvature of the convex and concave surfaces is the same as the curvature of the needle.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: the front end of the needle holder is designed to be a convex surface and a concave surface, so that the holding force of the needle holder is improved, when a suture needle is held by the needle holder, the needle holder can be automatically adjusted to a position vertical to the needle holder along the radian of the needle holder, the time is saved, and the left-hand assisted adjustment is omitted; the efficiency is improved, and the operation time is reduced; meet the requirements of various surgical suture

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:

FIG. 1 is a schematic structural view of a needle holder of the present invention;

FIG. 2 is a schematic view of a partial structure of a needle holder according to the present invention;

fig. 3 is a schematic cross-sectional view of a partial structure of a needle holder of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

Referring to fig. 1, 2 and 3, a needle holder, the needle holder includes first tong arm and second tong arm, first tong arm divide into first tong handle 1, first binding clip 2 and first connecting portion 3, the second tong arm divide into second tong handle 4, second binding clip 5 and second connecting portion 6, first connecting portion 3 and second connecting portion 6 are articulated fixedly through the pin, 2 inboard tong faces of first tong head are convex

surface

7, 4 inboard tong faces of second tong head are concave surface 8, the radian of convex surface 7 and concave surface 8 is identical, the surface of convex surface 7 and concave surface 8 all is equipped with the insection.

The tail end of the first forceps handle is provided with a first handheld ring 9, the inner side of the first handheld ring is provided with a limiting groove column 10, and a spring 11 is fixed in the limiting groove column.

The tail end of the second forceps handle is provided with a second hand-held ring 12, the inner side of the second hand-held ring is provided with a limiting column 13, and the limiting column 13 is clamped in the limiting groove column 10.

The curvature of the convex surface 7 and the concave surface 8 is the same as the curvature of the suture needle.

The convex surface 7 and the concave surface 8 can increase the holding force of the needle holder during operation, and when the needle holder holds the needle, the vertical position of the suture needle and the needle holder can be automatically adjusted along the radian of the needle holder and the suture needle, thereby saving time and saving left-hand assisted adjustment.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
