Passage bolt extracorporeal guiding device for pelvic and acetabulum fractures and methods for manufacturing and using same

Abstract

The invention provides a passage bolt extracorporeal guiding device for pelvic and acetabulum fractures and methods for manufacturing and using the same. The passage bolt extracorporeal guiding devicefor the pelvic and acetabulum fractures comprises a locator, a guider acquired by 3D printing, a guide needle and a guide needle sleeve which sleeves outside the guide needle, guide passages are arranged on the guider, and the guide passages comprise one or more of an acetabulum front column bolt guide passage, an acetabulum back column bolt guide passage, an ilium bolt guide passage, an acetabulum upper bolt guide passage, a sacroiliac bolt guide passage and a transsacral bolt guide passage. The passage bolt extracorporeal guiding device is accurate in locating and can be applicable to treating various types of pelvis and acetabulum fractures. The methods for manufacturing the passage bolt extracorporeal guiding device for the pelvic and acetabulum fractures and using the passage bolt extracorporeal guiding device are simple and easy to operate, the locating is accurate, and the device and methods are applicable to promotion.

Description

technical field

[0001] The invention relates to the field of orthopedic medical devices, in particular to an external channel screw guiding device for pelvic and acetabular fractures and a method thereof. Background technique

[0002] Due to the complex anatomy of pelvic acetabular fractures, there are many adjacent important tissues and organs, and the types of fractures are ever-changing. Traditional open reduction and internal fixation can directly look at the injured area, which is conducive to anatomical reduction. However, during the open operation, the soft tissue is exposed too much, the operation is complicated, and it is easy to damage important blood vessels and nerves. Therefore, the operation of pelvic and acetabular fractures is difficult. , Time-consuming, more bleeding, high risk.

[0003] At present, closed reduction and minimally invasive screw technology has gradually become the mainstream of treatment for pelvic acetabular fractures. The pelvic acetabul...
