Abstract

The utility model discloses an acetabular retractor structure, which comprises a handle integrally formed sequentially, a bent connection part and a hook body part; the hook body part is in the shape of a concave arc as a whole, and the arc length of the concave arc is 3 cm. The radius of the concave arc is 2.5cm, and the surface of the hook body is a serrated surface; the handle is generally in the shape of a round platform with a thick tail and a thin front, and the surface of the handle is processed with anti-slip knurling, and a through hole is opened at the tail of the handle; The above-mentioned bent connecting portion is arc-shaped with a radius of 4-5 cm. The hook portion is designed as an arc-shaped tooth-like structure, which is suitable for the morphological characteristics of the acetabulum and has a good gripping effect, which is not easy to cause acetabular damage; the handle is designed as a circular truncated shape to facilitate the doctor's gripping, and the gripping angle It is easier to adjust and will not block the view of the chief surgeon, which is conducive to efficient and smooth operation.

Description

A kind of acetabular retractor structure

technical field

The utility model belongs to the field of orthopedic surgical appliances, in particular to the structure of an acetabular retractor.

Background technique

  At present, Hoffman retractors are widely used clinically when exposing the acetabulum in artificial total hip arthroplasty, but the Hoffman retractors do not fully conform to the anatomical characteristics of the acetabulum, which brings difficulties to surgical exposure. Therefore, it is the wish of joint surgeons to invent a kind of retractor specially designed for artificial total hip replacement.

Contents of the invention

The technical problem to be solved by this utility model is to provide an acetabular retractor structure with reasonable structure, convenient use and suitable for total hip replacement surgery in view of the deficiencies in the prior art.

In order to achieve the purpose of this utility model, the following technical solutions are adopted: an acetabular retractor structure, which includes a handle, a bending connection part and a hook body that are sequentially integrally formed; the hook body is in a concave arc as a whole shape, the arc length of the concave arc is 3cm, the radius of the concave arc is 2.5cm, and the surface of the hook body is a serrated surface; Flower, the end of the handle is provided with a through hole; the bending connection part is arc-shaped with a radius of 4-5cm.

Compared with the prior art, the beneficial effect of the utility model is that: the hook part is designed as a circular arc-shaped tooth structure, which is suitable for the shape characteristics of the acetabulum and has a good grasping effect, and is not easy to cause acetabular damage; The handle is designed in the shape of a truncated cone to facilitate the doctor's grasping, and the grasping angle is easy to adjust, which will not block the surgeon's field of vision, which is conducive to efficient and smooth operation.
