Posterior column screw guiding plate and manufacturing method thereof

Abstract

The invention relates to a posterior column screw guiding plate. The posterior column guiding plate is characterized by comprising a baseplate (1) and a guiding pipe (2) positioned on the baseplate (1); the guiding pipe (2) is communicated with the bottom of the baseplate (1) at the bottom of the guiding pipe and integrated with the baseplate (1); the baseplate (1) includes a transverse fossa iliaca fitting plate (1.1) and a vertical crista iliaca fitting plate (1.2), wherein the inner side of the crista iliaca fitting plate (1.2) is connected to the outer side of the fossa iliaca fitting plate (1.1), and the fossa iliaca fitting plate (1.1) is integrated with the crista iliaca fitting plate (1.2). The posterior column screw guiding plate has the advantages that the manufacturing price islow, and positioning is accurate; by adopting the posterior column screw guiding plate, the frequency of fluoroscopy during an operation can also be reduced, and therefore damage caused to the human body after fluoroscopy is carried out several times is avoided.

Description

technical field [0001] The invention relates to a rear column screw guide plate and a manufacturing method thereof. Background technique [0002] Acetabular fractures and pelvic fractures are difficult points in trauma orthopedics, and they are technically difficult. Traditional open reduction involves large trauma, heavy bleeding, and slow postoperative recovery. With the improvement of surgical technology and the improvement of treatment concepts, posterior column screws are used in the treatment of acetabular fractures and pelvic fractures. Traditional posterior column screws need to adjust the direction of the guide pin under fluoroscopy so that the guide pin is located in the channel of the posterior column screw. The fluoroscopy time of the operation is long, and the sciatic nerve may be damaged due to improper operation. At present, some foreign and domestic hospitals use robot-assisted surgery, which greatly improves the accuracy and success rate of nail placement. ...

AI Technical Summary

Problems solved by technology

The traditional posterior column screw needs to adjust the direction of the guide pin under fluoroscopy so that the guide pin is located in the channel of the posterior column screw. The fluoroscopy time of the operation is long, and the sciatic nerve may be damaged due to improper operation.

At present, some foreign and domestic hospitals use robot-assisted surgery, which greatly improves the accuracy and success rate of nail placement. However, orthopedic robots are expensive, costing millions or tens of millions, which is not conducive to widespread promotion.
