Problems solved by technology

[0002] When the hospital uses intramedullary nails for bone marrow surgery, it must first use the guide needle tube to find the correct position, and then insert the guide nail. However, the guide needle tube of the PFNA intramedullary nail is difficult to use because the tube body is short, thin and smooth. Holding the guide needle tube in the hand not only affects the timely grasp of the position, but also increases the pain of the operation for the patient

Abstract

The invention provides a medical PFNA (Proximal Femoral Nail Anti-rotation) positioner. One side of a needle guide tube is connected with a positioning rod through a handle; the lower end of the needle guide tube is provided with a circular-tooth-shaped antiskid tube head; the upper end of the needle guide tube is provided with a trumpet-shaped tube insertion opening. During usage, shaking and deviation of the needle guide tube can be prevented through the positioning rod, meanwhile the lower end of the needle guide tube is provided with the antiskid tube head and accordingly the needle guide tube can be pierced at the intramedullary accurate position and the sliding can be avoided, and accordingly an intramedullary operation can be accurate and rapid in positioning, the operation time can speed up, and the pain of a patient during operation can be reduced.

Description

technical field [0001] The invention relates to a medical intramedullary nail positioning device, in particular to a medical PFNA intramedullary nail positioner. Background technique [0002] When the hospital uses intramedullary nails for bone marrow surgery, it must first use the guide needle tube to find the correct position, and then insert the guide nail. However, the guide needle tube of the PFNA intramedullary nail is difficult to use due to its short body, thin and smooth. Holding the guide needle tube in the hand not only affects the timely grasp of the position, but also increases the pain of the operation for the patient. Contents of the invention [0003] The purpose of the present invention is to provide a medical PFNA intramedullary nail locator, which has the characteristics of easy grasp, quick positioning and relieving pain of patients. [0004] The present invention includes a guide needle tube of a locator, and the adopted technical scheme is as follows...
