Femoral head fenestration device and using method thereof

Abstract

The invention discloses a femoral head fenestration device. The fenestration device comprises a fenestration bone knife, a handle and a miniature curette, the fenestration bone knife is formed by connecting a knife edge A, a knife edge B and a connecting end, the knife edge A and the knife edge B are spliced, the included angle between the knife edge A and the knife edge B is 45 degrees, and the knife edge A and the knife edge B are connected with the connecting end at the same time; the knife edge A and the knife edge B are the same in shape and are rectangular, the length of the edges of theknife edge A and the knife edge B is 1 cm, the length of the edges at the connection place is 2 cm, and the thickness is 1 mm; and the connecting end is connected with the handle, and the handle is located in the middle of the connecting end; the total length of the miniature curette is 3 cm, and the miniature curette comprises a cone with the height of 1.5 cm, a cylinder with the length of 1 cmand the diameter of 0.1 cm and a curette body with the radian of 15 degrees, the width of 1 mm and the thickness of 0.5 mm. By means of the femoral head fenestration device and the using method thereof, blood supply reconstruction after femoral neck subtype fracture becomes possible, and the necrosis rate and the non-healing rate after femoral neck fracture are reduced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of blood supply reconstruction after femoral neck fracture, which is used for the treatment of retinal vascular injury after femoral neck fracture, especially the blood supply reconstruction of femoral head after subcapital fracture and retinal vessel avulsion, and specifically relates to a Femoral head opener and method of use thereof. Background technique [0002] At present, femoral head necrosis and fracture nonunion after femoral neck fracture are still two difficult problems facing clinicians. There are many specific influencing factors, but at present it is more certain that it is closely related to the blood supply injury of the femoral head and neck. [0003] According to the research data, the current treatment methods for improving blood supply after femoral neck fractures include the transfer of blood supply bone flaps to treat femoral neck fractures, such as the greater trochanter bone flap, il...

AI Technical Summary

Problems solved by technology

However, this technical method can only be applied to patients with femoral neck base and transcervical fractures. For patients with subcephalic fractures, traditional treatment methods are still used, which cannot fundamentally solve the problem of avascular necrosis of the femoral head.
