tibial prosthesis sizer

Abstract

The invention relates to a tibial prosthesis size measurer, which comprises a depth measuring scale and a width measuring scale, wherein the depth measuring scale and the width measuring scale are arranged vertical to each other; the width measuring scale slides freely along the longitudinal direction of the depth measuring scale, is a telescopic scale, and comprises a telescopic rod and a slide bar; the right end of the slide bar is connected with the depth measuring scale; the right end of the telescopic rod is movably sleeved in a telescopic interface at the left end of the slide bar. The tibial prosthesis size measurer is simple in structure; both the depth measuring scale and the width measuring scale are provided with scale marks, so that an operator can directly read out the width and depth of a platform conveniently through the scale marks, errors are avoided, and measured data are accurate; hooks on the scales are convenient for hooking the edges of bones, so that convenience is brought to operation and use; the width measuring scale is a telescopic scale, so that convenience is brought to measurement and use; the measurer is simple in overall structure, and suitable for measuring at small incisions.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to the technical field of orthopedic measurement equipment, in particular to a tibial prosthesis size measuring device. Background technique [0002] At present, for unicondylar knee arthroplasty (UKA), the accurate selection of the size of the prosthesis will ultimately affect the surgical effect and long-term survival rate of the prosthesis. Due to minimally invasive surgery, it is difficult to perform such surgery as in total knee arthroplasty. Accurate measurement of tibial prosthesis size. At present, the commonly used tibial prosthesis size measurement is mostly to put different sizes of tibial prosthetic templates into the operation and directly compare the size. Due to the limited intraoperative field of view, the prosthesis is often chosen incorrectly. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shor...

[0002] At present, for unicondylar knee arthroplasty (UKA), the accurate selection of the size of the prosthesis will ultimately affect the surgical effect and long-term survival rate of the prosthesis. Due to minimally invasive surgery, it is difficult to perform it as in total knee arthroplasty. Accurate measurement of tibial prosthesis size

At present, the commonly used tibial prosthesis size measurement is mostly to put different sizes of tibial prosthetic templates into the operation to directly compare the size. Due to the limited field of view during the operation, the prosthesis is often chosen incorrectly.
