Operation guide plate and method for wrist fracture percutaneous fixation

Abstract

The invention relates to an operation guide plate and method for wrist fracture percutaneous fixation. The operation guide plate comprises a palm side plate and a back side plate, the side face of the palm side plate is provided with a palm wrist fixing groove matched with the palm side face of the wrist of a human body, the side face of the back side plate is provided with a back wrist fixing groove matched with the palm back side face of the wrist of the human body, a wrist fixing groove is formed after the palm wrist fixing groove and the back wrist fixing groove are spliced, the wrist fixing groove is matched with the wrist of the human body, the palm side plate is provided with a guide tube, steel needles are contained inside a tube hole of the guide tube, and the extending direction of the tube hole is in accordance with the longitudinal axis direction of a navicular bone of the wrist of the human body. The using method comprises the following steps that the palm side face of the wrist is placed in the palm wrist fixing groove; the back side plate and the palm side plate are correspondingly spliced; the steel needles are inserted into the guide tube, and the navicular bone is punctured through the steel needles. According to the operation guide plate and method for wrist fracture percutaneous fixation, the introducing process of steel needle puncture is simplified, the puncture positions of the steel needles are accurately positioned, the success rate of one-time needle puncturing is increased, damage to sclerotin is reduced, the operation time is shortened, and pain of a patient is relieved.

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.
