Femoral neck fracture hollow screw imbedding guide device

Abstract

The invention discloses a femoral neck fracture hollow screw imbedding guide device. The femoral neck fracture hollow screw imbedding guide device comprises a first guide base body and a second guidebase body, the second guide base body is detachably connected to the first guide base body, the first guide base body is provided with at least one first hole, the second guide base body is provided with at least two parallel second holes, the first hole is used for inserting a guide needle within a preset angle range, and the second holes are used for inserting the guide needle with a preset angle. By means of the femoral neck fracture hollow screw imbedding guide device, on the basis of achieving a good treatment effect, the treatment cost of a patient can also be greatly lowered.

Description

Technical field [0001] The invention relates to orthopedic medical equipment, in particular to a guide device for inserting hollow screws for femoral neck fractures. Background technique [0002] Existing femoral neck fractures, especially femoral neck fractures in young people, usually adopt hollow screw placement methods. The placement of hollow screws has always been the focus of clinicians’ research to find a way that can benefit the femoral neck. Hollow screw placement for fracture healing. [0003] For femoral neck fractures, there are currently two known requirements for internal fixation: 1. The internal fixation is strong enough to prevent the fracture end from shifting during weight bearing or exercise, especially in terms of resisting the shear force of the fracture end. Sufficient; 2. The compression force between fracture sections is another important factor in the healing of femoral neck fractures, because the femoral neck is located in the dry hip joint capsule with...

AI Technical Summary

Problems solved by technology

The existing hollow screw insertion method is usually by first inserting multiple guide pins in parallel, and then inserting multiple parallel hollow screws along the multiple parallel guide pins. Excessive compression, especially when bearing weight or exercising, often leads to insufficient compression of the fracture surface, unable to resist fracture shearing force, thus affecting the healing of femoral neck fractures

In order to meet the resistance to the shear force of the fracture end, the traditional solution is to place more hollow screws or add steel plates, or even use titanium nails and titanium plates, which will inevitably lead to a great increase in the cost of treatment for patients
