Abstract

The invention relates to the technical field of arthroscopic surgery, in particular to an approach guide rod. The approach guide rod comprises a rod body, wherein a strip-shaped guide groove is formedin the side wall (peripheral wall) of the rod body, the length direction of the guide groove is consistent with that of the rod body, the tail end of the guide groove penetrates through the tail endof the rod body, and the guide groove is used for sliding arrangement of a puncture needle. The provided approach guide rod can guide the puncture needle to the designated position through the guide groove in the rod body after the position of an articular cavity is found out, so that an approach of the arthroscopic surgery can be established, the perspective link during approach establishment inrelated art can be omitted, and the approach is accurate and efficient to establish. Besides, the guide groove is formed in the side wall of the rod body, that is, the rod body is arranged in a semi-open structure manner, and accordingly, a doctor performing the surgery conveniently puts the puncture needle into the guide groove. The provided approach guide rod is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of arthroscopic surgery, in particular to an approach guide rod. Background technique [0002] The hip joint is composed of the femoral head and the acetabulum, which is a ball and socket joint. The lunate surface of the acetabulum is covered with articular cartilage, and the acetabular fossa is filled with fat, also known as the Haversian gland, which can be squeezed out or inhaled with the increase or decrease of intra-articular pressure to maintain the balance of intra-articular pressure. At the edge of the acetabulum, there is an attachment of the glenoid rim, which deepens the wrapping and stability of the acetabulum to the femoral head. The transverse acetabular ligament crosses the acetabular notch and forms a hole with the notch through which nerves and blood vessels pass. Functional lesions of the hip mainly include hip impingement, hip labrum injury, osteoarthritis, aseptic bone necrosis (such as...
