Abstract

The utility model relates to a hip joint reference scale which comprises a base plate and a dimension and mark line carved on the base plate. The base plate is of a rectangular structure and made from high-temperature-resistant radioparent medical materials, and the dimension and mark line is made from roentgen-opaque medial metal materials; the dimension and the mark line is used for measuring lengths, angles and diameters; the base plate is made from TPX or PMMA or PPSU; the dimension and mark line is made from stainless steel or cobalt-based alloys or titanium-based alloys. According to the hip joint reference scale, the reference dimensions of bones can be overlapped and developed in a perspective mode before and in an operation through the hip joint reference scale, a reference basis can be provided for the operation, the success rate of surgical implanting can be enhanced, and the operation time of surgical implanting can be shortened.

Description

A kind of hip joint reference scale

Technical field:

This utility model relates to medical auxiliary apparatus apparatus field, relates in particular a kind of hip joint reference scale.

Background technology:

Orthopaedics replacement of total hip is by surgical repair method, artificial hip prosthesis to be replaced and implants hip joint position, is widely used in the advanced technology that the hip joint disease that current conventional treatments cannot cure is repaired in treatment.That the related parameter choosing of wherein performing the operation needs is preoperative, from skeleton fluoroscopic image, obtain relevant information in art, now just needs a kind of hip joint reference scale, before operation and in operation, can overlapping perspective development skeleton reference dimension, and for operation provides better reference frame.

Utility model content:

The purpose of this utility model is for the deficiencies in the prior art part, a kind of hip joint reference scale is provided, it can provide energy overlapping perspective development skeleton reference dimension before operation and in operation, can provide better reference frame for operation, increase Srgery grafting success rate, reduce Srgery grafting operating time.

Technology solution of the present utility model is as follows:

A reference scale, it comprises base plate and is engraved in size and the mark line on base plate; Described base plate is rectangle structure; Described base plate is to be made by the high temperature resistant medical material of radioparent, and mark line is to be made by radiopaque medical metal material; Described size and mark line comprise size and the mark line of measuring length, angle and diameter.

As preferably, the material of described base plate is TPX, PMMA or PPSU.

As preferably, the material of described mark line is rustless steel, cobalt-base alloys or titanium-base alloy.

The beneficial effects of the utility model are:

Hip joint reference scale of the present utility model, the base plate of the high temperature resistant medical material system of radioparent, the mark line of radiopaque medical material system, conventional length, angle and the diameter dimension measured of mark line sign operation on hip joint, can before operation and in operation, provide energy overlapping perspective development skeleton reference dimension, and not block image on a large scale, can provide better dimension reference foundation for operation, increase Srgery grafting success rate, reduce Srgery grafting operating time.

Accompanying drawing explanation:

Below in conjunction with accompanying drawing, this utility model is described further:

Fig. 1 is structural representation of the present utility model;

In Fig. 1: 1-base plate; 2-mark line.

The specific embodiment:

Embodiment, is shown in accompanying drawing 1, a kind of hip joint reference scale, and it comprises base plate 1 and is engraved in size and the mark line 2 on base plate; Described base plate is rectangle structure; Described base plate is to be made by the high temperature resistant medical material of radioparent, and mark line is to be made by radiopaque medical metal material; Described size and mark line comprise size and the mark line of measuring length, angle and diameter, before surgical operation or in operation under overlapping perspective with reference to hip joint size chi; The mark line of radiopaque material system, can contrast patient's skeleton size angle by mark line.In Fig. 1: 36/4 represents that smallest circle arc dia is 36mm, increases progressively with 4mm toward all the other arc diameters of outside; 35/5 represents that 1/4 circular arc least radius is 35mm, toward all the other 1/4 arc radius of outside, with 5mm, increases progressively; 120 °/5 ° represent that nearest this straight line and below vertical line angle are 120 °, increase progressively counterclockwise toward all the other straight lines of outside and below vertical line angle with 5 °; 60/10 represents that the distance having identified between arrow is 60mm, and down every lattice increase progressively with 10mm; 16/2 represent recently this vertical curve apart from the long vertical line in the leftmost side apart from being 16mm, every lattice of turning left 2mm that successively decreases; 24,28,32,36 represent this diameter of a circle.

The material of described base plate is TPX, PMMA or PPSU.

The material of described mark line is rustless steel, cobalt-base alloys or titanium-base alloy.

Above-described embodiment is the specific descriptions that this utility model is carried out; just this utility model is further described; can not be interpreted as the restriction to this utility model protection domain, within those skilled in the art makes some nonessential improvement according to the content of above-mentioned utility model and adjusts and all to fall into protection domain of the present utility model.
