Femoral head puncture guiding device

Abstract

The invention discloses a femoral head puncture guiding device. The device comprises a sheathing canal assembly and a guiding needle group assembly, wherein the sheathing canal assembly is formed by welding of a sheathing canal and a hollow internal conical locking joint head, the tail end of the sheathing canal is provided with a tooth-shaped blade structure and an anti-blockage-and-infiltrationhole, the guiding needle group assembly comprises a puncture guiding needle, an external conical locking joint head and a connecting column, the tail end of the external conical locking joint head isprovided with a connecting threaded groove fitted with a threaded connecting end of the internal conical locking joint head, the connecting column is arranged in the middle of the connecting threadedgroove, the connecting column is connected with the puncture guiding needle, the connecting column is fitted with a hollow structure of the internal conical locking joint head, and the puncture guiding needle is fitted with an inner cavity of the sheathing canal. According to the puncture guiding device, large-area open treatment of a patient can be prevented and injection treatment of a femoral head is completed, so that pain of the patient is relieved and healing time of the patient is reduced.

Description

technical field [0001] The invention relates to the field of medical surgical instruments, in particular to a femoral head puncture guide. 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. There are many important structures around it. Hip joint diseases such as ankylosing spondylitis and hip arthritis can cause pain and dysfunction of the hip joint, and the progressive aggravation of the disease will seriously affect the quality of life of the patient, and the disability rate is high. At present, there is no clear treatment method in the early and middle stages, and the surgical treatment in the late stage is mainly joint replacement. For patients with hip joint diseases who do not need or cannot tolerate surgery in the early and middle stages, clinically, hip joint puncture fluid testing, drug injection treatment, and bone biopsy around the hip joint are currently import...

AI Technical Summary

Problems solved by technology

Due to the deep position of the hip joint and the surrounding important nerves and blood vessels, the traditional puncture method is prone to repeated punctures, damage to nerves and blood vessels, etc.

For example, the puncture of the femoral head currently relies on the perspective of the X-ray machine and the doctor's knowledge of the anatomical knowledge of the femoral head. There is no necessary auxiliary equipment, the skin incision is large during the operation, the damage to the soft tissue and bone tissue is large, the operation time is long, and the operation Inaccurate
