Abstract

The utility model relates to a can solve the thighbone and do whether there is the thighbone wheel measuring appearance rotatory unusual and aassessment of thighbone throat inclination between comminuted fracture or thighbone rotor among the fracture surgery after the reduction of the fracture, the opening part of under shed rectangle frame is equipped with the internal thread swing arm in being equipped with flexible arm of frame and the flexible arm of frame respectively, protractor for having the flagging pointer of activity on the under shed rectangle frame. The advantage: this application does whether there is aassessment simple accurate rotatory unusual and thighbone throat inclination between comminuted fracture or thighbone rotor among the fracture surgery after the reduction of the fracture to the thighbone, and the aassessment is accurate.

Description

Femoral rotation measuring instrument

Technical field

This utility model relates to a kind ofly can solve in comminuted fracture of femoral shaft or intertrochanteric fracture operation whether there is the femoral rotation measuring instrument rotating exception and anteversion of femoral neck assessment after the reduction of the fracture, and femoral rotation measuring instrument manufactures field.

Background technology

CN2181259Y, title " angle measurer for upper of femur ", be made up of angular surveying part and linear measure longimetry part, it is characterized in that there is a slide sign 6 on the footage number 7 with dovetail groove 4 and quiet claw 8, it there is claw 9, slide sign moves and turn round 10 and braking bolt 5, dovetail groove 4 is equipped with an angle scale 1, there is a visible marking 17 at 23 ° of places on angle scale, and the handle of angle scale is equipped with by angle pin bolt 3 angle pin 2 and collodiaphyseal angle chaining pin fixed block 11 and collodiaphyseal angle chaining pin braking bolt 13 and collodiaphyseal angle chaining pin 12 that a centre is strip hole 16.Its weak point: cannot complete in comminuted fracture of femoral shaft or intertrochanteric fracture operation whether there is the Measurement accuracy and assessment that rotate exception and anteversion of femoral neck after the reduction of the fracture.

Summary of the invention

Purpose of design: avoid the weak point in background technology, designs a kind ofly can solve in comminuted fracture of femoral shaft or intertrochanteric fracture operation whether there is the femoral rotation measuring instrument rotating exception and anteversion of femoral neck assessment after the reduction of the fracture.

Design: comminuted fracture of femoral shaft or the common classification of fracture of intertrochanteric fracture, often needs to measure the distal femur anglec of rotation and rotates extremely to determine whether anteversion of femoral neck or distal femur exist after the reduction of the fracture in operation technique.This utility model, in structural design, is reached the standard grade determine femoral rotation by being demarcated relatively-stationary condyle of femur.That is, by the frame structure of a rectangle, telescopic arm is fixed on lateral epicondyle in femur, connects the half-round compasses that a pointer is movable sagging, directly read the anglec of rotation from half-round compasses under fixed arm.

Technical scheme: a kind of femoral rotation measuring instrument, the opening part of under shed rectangle frame framework telescopic arm is housed respectively and framework telescopic arm built with female thread swing arm, under shed rectangle frame is the half-round compasses with the sagging pointer of activity.

This utility model is compared with background technology, and the application is simple and easy to do for whether there is the assessment rotating exception and anteversion of femoral neck after the reduction of the fracture in comminuted fracture of femoral shaft or intertrochanteric fracture operation, and assessment accurately.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of femoral rotation measuring instrument.

Detailed description of the invention

Embodiment 1: with reference to accompanying drawing 1.A kind of femoral rotation measuring instrument, the opening part of under shed rectangle frame 2 framework telescopic arm 3 is housed respectively and framework telescopic arm built with female thread swing arm 1, under shed rectangle frame 2 is the half-round compasses 4 with the sagging pointer of activity.Lateral epicondyle in rotating female screw swing arm 1 resected femur 5.

It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present utility model; but these text descriptions; just the simple text of this utility model mentality of designing is described; instead of the restriction to this utility model mentality of designing; any do not exceed this utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.

Claims
