Abstract

The invention relates to the technical field of medical apparatus and instruments, and particularly relates to an operation thighbone retractor. The operation thighbone retractor includes a fixing support, an adjustment rod fixed on the fixing support, a primary drawing hook and a secondary drawing hook; the secondary drawing hook matches the primary drawing hook and is detachably connected to the primary drawing hook; and the primary drawing hook is adjustably connected to the fixing support. The operation thighbone retractor is simple in structure, is adjustable in height and angle, is easy to operate, can save physical power, reduce complication, is safe and reliable, is flexible in adjustment, and is wide in adaptation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a femoral hook device for surgery. Background technique [0002] General surgery is a clinical discipline with the longest history and the most mature development among all surgeries. With the rapid development of medicine, the continuous refinement of disciplines, the continuous improvement of treatment methods, and the introduction of new technologies and methods have made general surgery treatment play a more important role. Many diseases that could not be treated in the past can now be cured by surgery, which greatly improves the cure rate of diseases and the quality of life of patients. And as one of the important departments of the hospital, general surgery also plays an important role in teaching and scientific research. [0003] Hip replacement is an important surgical procedure. Artificial hip replacement refers to a prosthesis similar to human bone joints ...
