Description

Guide needle

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a guide needle.

Background

The guide needle is an auxiliary instrument commonly used for clinically making 0# to 2# absorbable threads, and is most frequently used when the operation is carried out on the face, the neck, the abdomen and the perineum. The traditional guide needle is in a straight cylinder shape, is sleeved outside the sawtooth-shaped absorbable line and can only pass through the guide needle in a straight line, but the skin of the face of a human face is in a fluctuating distribution along with the change of the contour of the skull. The straight cylindrical guide needle is anatomically hindered or is difficult to reach the deepest part of wrinkles in the advancing process, and the operation is inconvenient when the straight cylindrical guide needle meets the parts needing bending, such as the skull, the vagina and the like, so that the postoperative effect of many patients is not obvious. Many patients with severe facial laxity are not satisfied with the effect of the pre-buried line lifting, resulting in medical disputes.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a guide needle can adapt to various physiological curvatures, and it is that clinician when carrying out face, neck, belly and perineum operation, greatly reduced the operation degree of difficulty, improved the operation quality, alleviateed patient's misery simultaneously.

In order to achieve the above object, the present invention provides the following specific technical solutions:

the guide needle comprises a guide needle body, wherein the guide needle body comprises a holding part and a working part, the working part consists of a bending section and a connecting section for connecting the bending section and the holding part, the connecting section is rod-shaped, the bending section is arc-shaped, and the axis of the connecting section is not parallel to the plane formed by the bending section.

Preferably, the junction of the connecting section and the bending section is smoothly transited.

Preferably, the free end of the bending section is provided with a needle head, and the needle head is provided with a through hole and a threading hole.

Preferably, the cross section of the needle head is circular or triangular, and the through hole is circular.

Preferably, the inner diameter of the through hole is larger than the cross-sectional diameter of the wire.

Preferably, the curved section is semi-circular.

Preferably, the axis of the connecting section is perpendicular to the plane formed by the curved sections.

Preferably, the holding portion comprises a handle for operation by a user, and the holding portion and the working portion are connected by a holding knob.

Preferably, the working portion is made of a metal material.

The utility model has the advantages that:

1. the front section of the guide needle is in semicircular bending, so that the guide needle can adapt to various physiological bending encountered in clinical operation, and the operation efficiency of doctors is improved.

2. The guide needle of the utility model has simple structure, reliable connection and convenient assembly and disassembly.

3. The guide needle of the utility model has reasonable structure, convenient use, simplified operation process and lower manufacturing cost.
