Surgical guide plate and method for percutaneous fixation of wrist fracture

Abstract

The invention relates to a surgical guide plate and method for percutaneous fixation of wrist fractures. The surgical guide plate includes a palm side plate and a dorsal side plate. The palm side plate is provided with a palmar wrist fixing groove and matches with the palmar side of the human wrist. There is a dorsal wrist fixing groove on the side of the back side plate and matches the dorsal side of the palm of the human wrist. After the palm and wrist fixing grooves and the dorsal wrist fixing groove are combined to form a wrist fixing groove, the wrist fixing groove matches the human wrist. , the volar side plate is provided with a guide tube, the steel needle is accommodated in the tube hole of the guide tube, and the extension direction of the tube hole is consistent with the longitudinal axis direction of the scaphoid bone of the human wrist. The use method comprises the following steps: the palm side of the wrist is placed in the palmar wrist fixing groove; the dorsal plate and the palm side plate are joined together; the steel needle is inserted into the guide tube and the steel needle punctures the scaphoid bone. The invention simplifies the introduction process of the steel needle puncture, accurately locates the puncture position of the steel needle, increases the success rate of one-time needle puncture, reduces the damage to bone, shortens the operation time, and relieves the pain of the patient.

Description

technical field [0001] The invention belongs to the field of surgical assistance for percutaneous fixation of wrist fractures in orthopedics, in particular to a surgical guide plate and method for percutaneous fixation of wrist fractures. Background technique [0002] When performing percutaneous fixation of wrist scaphoid fractures, the operator needs to use steel needles to penetrate the fractured wrist bone longitudinally without making skin incisions to achieve fixation of the fracture site, but this operation is technically difficult and The requirements are high, and even a doctor with considerable clinical experience is difficult to succeed at one time. It takes multiple attempts and filming to adjust the needle insertion point and direction. For inexperienced doctors, repeated needle insertion failures will cause bone destruction, affect the healing ability of the bone, prolong the operation time, and increase the pain of the patient.
