Proximal femur operation positioning and orientating system and manufacturing method thereof

Abstract

The embodiment of the invention provides a proximal femur operation positioning and orientating system and a manufacturing method thereof.The system comprises an attaching device, an orientating device and a depth limiting device; the attaching device is used for being attached to the proximal femur and manufactured according to the anatomical form of the proximal femur, and the attaching device comprises an attaching portion attached to the proximal femur and a connecting portion connected with the orientating device; the orientating device is used for indicating the direction of a lesion of a patient and comprises a guide plate, and the guide plate is connected with the connecting portion and provided with a guide hole for indicating the direction of the lesion; the depth limiting device is used for limiting the depth that an operative instrument enters the lesion of the patient in the direction indicated by the orientating device, connected with the guide plate and arranged to be capable of enabling an operator to be able to perform at least one of the following operations of arriving at the lesion, building an operation channel and placing an implant through the guide hole under assistance of the depth limiting device.

Description

technical field [0001] The disclosure relates to the field of medical devices, in particular to a proximal femur surgical positioning and orientation system and a manufacturing method thereof. Background technique [0002] The proximal femur includes the femoral head, the intertrochanter, and the proximal femoral shaft. These parts are often affected by various diseases, such as benign and malignant tumors, infection, avascular necrosis of the femoral head, and fractures (the incidence of femoral head necrosis is relatively high in China). When treating these diseases, some surgical procedures, such as tissue biopsy, lesion debridement, bone grafting, various implants and drug placement, often need to reach the lesion (for example, using surgical instruments). In addition, the fixation used to prevent fractures or treat fractures also requires that the internal fixation equipment have sufficient holding force and form a spatial geometric configuration with optimal mechanica...

Problems solved by technology

This will inevitably lead to excessive dependence on radiation, and will also cause radiation damage to patients and doctors

In addition, how to accurately find the lesion in three-dimensional space (accuracy is the most important factor that affects the effectiveness of the operation), how to protect healthy bone tissue to the greatest extent, accurately obtain and / or remove the lesion, and how to obtain and / or remove the lesion when it is most needed. Reconstruction and / or fixation of the site, these are issues that have yet to be perfected
