Individual hip joint percutaneous puncture guider and using method thereof

Abstract

The invention relates to an individual hip joint percutaneous puncture guider and a using method thereof. The guider comprises a guiding body matched with the hip joint of a human body; two ends of the guiding body are respectively provided with first through holes corresponding to femoral great trochanters on two sides of a human body; two second through holes corresponding to pubes on two sides of the pubic joint of a human body are formed in the middle of the guiding body; each second through hole on the guiding body outward and obliquely upward extends to form an auxiliary part; third through holes corresponding to anterior inferior spines on two sides of a human body are formed in the two auxiliary parts; U-shaped grooves are formed in boundaries of the first, second and three through holes; and at least one guide post is arranged on the guiding body. The hip joint percutaneous puncture guider and the using method thereof can be used for conveniently avoiding important great vessels around the hip joint during puncture treatment on the hip joint of a human body, so that the accuracy and safety of puncture can be guaranteed, the treatment efficiency can be improved, and pains of patients can be relieved. The individual hip joint percutaneous puncture guider has a simple structure, and has relatively good reliability and stability.

Description

Technical field

[0001] The invention relates to the technical field of medical devices, in particular to an individualized hip joint percutaneous puncture guide and a method of use thereof. Background technique

[0002] The human hip joint has a relatively stable bony structure. It is one of the main weight-bearing joints of the human body. Its location is deep and there are many important surrounding structures. It is a frequently-occurring joint in clinic, prone to osteoarthritis and rheumatoid hips. Hip joint diseases such as arthritis, ankylosing spondylitis and hip arthritis can cause pain and dysfunction of the hip joint. The progressive aggravation of the condition will seriously affect the quality of life of the patient, and the disability rate is high. At present, there is no clear treatment in the early and mid-term, and the late surgical treatment is mainly joint replacement. For patients with hip joint disease who do not need or can not tolerate surgery in the early ...

[0052] Example 2: A method of using an individualized hip joint percutaneous puncture guide, which will be combined below Figure 4 The method of using the individualized percutaneous puncture guide for the hip joint of the present invention will be described in detail.

[0053] Such as Figure 4 As shown, a method of using an individualized hip joint percutaneous puncture guide includes the following steps:

[0054] Step 1: Snap the left guide plate 11 and the right guide plate 12 together to form a guide body 1, and bring the guide body 1 close to the hip joint from the front side of the human body;

[0055] Step 2: Align the first through hole 2, the second through hole 3 and the third through hole 5 respectively at the greater trochanter, pubic bone and anterior inferior iliac spine on both sides of the human body and wear;

[0056] Step 3: Change the shape of the guide body 1 along the hip joint of the human body to make it fit the body surface of the human hip joint completely,...
