Embodiment Construction

[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] At present, the perineal column on the market is made by traditional technology, and the material is relatively single, and the cost is not low. However, the present invention uses 3D printing technology and EM+21 engineering resin to make the perineal column to solve the problem of hip arthroscopic surgery. Nerve damage and other problems often occur due to the reverse support force applied to the genitals. At the same time, the method is simple and low in cost, and structures with different internal void shapes can be designed according to requirements, so as to meet the requirements of reducing the impact on the perineum through the improvement of materials ...

Abstract

The invention provides a perineal column for hip arthroscopic surgery, comprising: the perineal column is a hollow cylinder structure in the shape of a honeycomb hole as a whole, and the hollow cylinder structure is a coaxial central channel, a support layer, and a contact layer from the inside to the outside. , the hardness of the support layer is greater than the hardness of the contact layer. Its advantages are: the fiber structure in the support layer is relatively thick, and the mechanical strength is relatively hard, so as to maintain the huge stress during the traction during the operation; The patient can be protected during the entire traction process.

Description

technical field [0001] The invention relates to the field of orthopedic medical technology, in particular to a method for preparing a perineal column for hip arthroscopic surgery. Background technique [0002] Hip arthroscopy is the mainstream minimally invasive form of hip surgery in recent years. Compared with open surgery, hip arthroscopic surgery has the characteristics of less bleeding, shorter postoperative recovery time, fewer postoperative complications, and less damage to the femoral head, reducing the risk of avascular necrosis. With the development of hip arthroscopy, its current indications have covered primary pathological changes in the hip joint and the assessment of peritrochanteric space disease, trauma, hip fracture, childhood hip disease, and pain after total joint replacement . Because of this, hip arthroscopy plays an increasingly important role in orthopedics, especially hip surgery. [0003] Before hip arthroscopy, it is necessary to use a traction ...
