Abstract

The invention discloses a measurer used for total hip replacement arthroplasty in the orthopedics department, and relates to the technical field of medical instruments. The aim is to improve the precision of the arthroplasty. The measurer comprises a measuring base, a transverse measure gauge capable of sliding in the left-and-right direction is transversely arranged on the measuring base, and a vertical measure gauge capable of sliding in the vertical direction is vertically arranged on the measuring base; the transverse measure gauge and the vertical measure gauge are straight gauges used for measuring lengths, and a measure gauge locking part used for locking the transverse measure gauge and the vertical measure gauge is arranged on the measuring base; a positioning rod capable of sliding in the vertical direction is vertically arranged at the right end of the transverse measure gauge, a tension measure spring is arranged on the transverse measure gauge, and a dial indicator used for detecting the elasticity of the tension measure spring is arranged on the measuring base. The measurer is suitable for measuring the length of a limb, eccentric distance and soft tissue tension of glutenus medius in the total hip replacement arthroplasty in the orthopedics department.

Description

technical field [0001] The invention relates to medical device technology, in particular to a measuring device technology used in orthopedic total hip arthroplasty. Background technique [0002] In orthopedic total hip arthroplasty, appropriately extending the shortened limbs of the patient is of great significance in restoring the equal length of the lower limbs of the patient, ensuring the normal walking of the patient after the operation, and prolonging the life of the artificial prosthesis. Moreover, restoring the normal eccentricity of the patient during the operation can help the patient recover normal gluteus medius abductor muscle strength as soon as possible, while reducing the mechanical load of the prosthesis and reducing the long-term loosening rate of the prosthesis. However, at present, the restoration of eccentricity relies on the operator's visual judgment based on experience. The accuracy of this method of manual judgment based on experience is extremely low...
