Guider for fixing dynamic hip screws for proximal femoral fractures

Abstract

The invention belongs to the field of medical apparatus and instruments and discloses a guider for fixing dynamic hip screws for proximal femoral fractures. A base plate is arranged at one end of the guider; a connection post is connected to the base plate; a handle is arranged at one end of the connection post; a plurality of parallel needle guide tubes are connected to the base plate and the connection post; needle guide holes are formed in two ends of the needle guide tubes and opened on the base plate and the connection post. When using, a guide needle is drilled into an optional needle guide hole firstly and then the required needle guide holes are selected according to the actual requirement. The guider is simple in structure, accurate and reliable in guide and location, good in use effect and capable of shortening operation time and reducing hemorrhage during operation and medical X-ray radiation.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a dynamic hip screw fixation guide for proximal femur fractures. Background technique [0002] Proximal femoral fracture is one of the common fractures in clinic, and it is mainly treated by surgical open reduction and internal fixation. Dynamic hip screw (DHS) internal fixation is currently the most commonly used surgical method for the treatment of proximal femoral fractures. One of the key operations in the surgery is to place a positioning guide pin, which determines the position and direction of the screw in the femoral neck. The insertion position is the main factor to prevent femoral resection. Improper placement of the guide pin will lead to unstable fracture fixation, fracture malunion, femoral head necrosis and other complications. [0003] With the conventional DHS guide, only one guide wire can be drilled in. If the position of the guide pin is found to be high or low ...

Dynamic hip screw (DHS) internal fixation is currently the most commonly used surgical method for the treatment of proximal femoral fractures. One of the key operations in the surgery is to place a positioning guide pin, which determines the position and direction of the screw in the femoral neck. The insertion position is the main factor to prevent femoral resection. Improper placement of the guide pin will lead to unstable fracture fixation, fracture malunion and femoral head necrosis and other complications.

[0003] With the conventional DHS guide, only one guide wire can be drilled in. If the position of the guide pin is found to be high or low during the operation, it is often necessary to take out the guide and the guide pin and drill in again after adjustment. If not satisfied, The operation needs to be repeated again, resulting in the need for repeated C-arm X-ray machine fluoroscopy during the operation, which will cause great harm to both the patient and the doctor
