Description

Opening distance measuring fixer for magnetic resonance temporomandibular joint scanning

Technical Field

The invention relates to the technical field of magnetic resonance detection, in particular to an opening distance measuring fixer for magnetic resonance temporomandibular joint scanning.

Background

The temporomandibular joint disease increases and the degree of attention paid to is increasing clinically at present, magnetic resonance examination is the most effective examination means, due to the particularity of the magnetic resonance examination, the scanning time of the temporomandibular joint is very long, and a part of the scanning sequence requires that a patient opens the mouth as much as possible to measure the distance of forward slippage of the mandibular joint head, and due to different disease conditions of each patient, the size of the opened mouth is different, and meanwhile, because of the disease conditions and the longer scanning time, the patient cannot keep a fixed opening angle for a long time.

Therefore, the detection time is increased, and detection dead angles are easy to exist.

Disclosure of Invention

The invention aims to provide an open distance measuring fixer for magnetic resonance temporomandibular joint scanning, which solves the problems in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a magnetic resonance temporomandibular joint scans uses opening distance measurement fixer, includes the fixer body, the fixer body is formed by the coincide of multilayer cylinder, and the centre of a circle coincidence of a plurality of cylinders is on same vertical line, and the diameter of multilayer cylinder is from bottom to top in proper order the equant number increase progressively, and the upper surface centre of a circle department fixedly connected with of fixer body connects the square, connects the square and installs the ring with moving ground.

Furthermore, a binding band is slidably connected in the circular ring in a penetrating mode, the fixator is worn on the neck of a patient through the binding band, and the fixator body is convenient to fit with the mouth of the patient for measurement.

Preferably, the binding band is made of an elastic band and is used for providing pre-tightening force between the fixer body and the mouth of the patient when the fixator is worn.

Preferably, the fixer body, the connecting square block and the ring are all made of medical PP plastics.

Preferably, the diameter of the multi-layer cylinder of the fixator body is 25, 30, 35, 40, 45, 50 and 55mm from bottom to top in sequence.

Preferably, the thickness of each layer of cylinders is 5mm.

Advantageous effects

This magnetic resonance temporomandibular joint scans uses opening distance measurement fixer, possesses following beneficial effect:

this open distance measurement fixer is used in magnetic resonance temporomandibular joint scanning, when the inspection is opened one's mouth, the advice patient opens the mouth to the biggest angle as far as possible, then the ring of taking, make that the less one of locating plate body diameter put into the mouth down, the card is on upper and lower incisor, in order to reach fixed effect, the distance of incisor about also can taking notes simultaneously, this structure wholly adopts medical PP plastics, non-toxic safety, do not influence magnetic resonance equipment's work simultaneously, in long-time testing process, it is fixed to the patient is opened one's mouth, reduce mouth muscle fatigue, overall structure is simple, no disinfection dead angle, use after being convenient for disinfect.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an open distance measuring fixer for magnetic resonance temporomandibular joint scanning is characterized in that a fixer body 1 is formed by overlapping a plurality of cylinders, the centers of circles of the cylinders are overlapped on the same vertical line, the diameters of the cylinders are sequentially increased in an equal number from bottom to top, a connecting block 2 is fixedly connected to the center of the circle of the upper surface of the fixer body 1, and a circular ring 3 is movably mounted on the connecting block 2.

The ring 3 is arranged to facilitate the daily taking of the fixer by patients and medical staff.

The fixer body 1, the connecting square 2 and the circular ring 3 are all made of medical PP plastics, the diameters of the multiple layers of cylinders of the fixer body 1 are 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm and 55mm from bottom to top in sequence, and the thickness of each layer of cylinder is 3-5mm.

When the fixator is used, the binding bands 4 can be inserted into the circular rings 3, the fixator can be worn on the neck of a patient through the binding bands 4, meanwhile, when magnetic resonance detection is conducted, the binding bands 4 are made of elastic bands, the fixator body 1 can be fixed through the binding bands 4, the fixator body 1 is prevented from being accidentally separated from the mouth, and meanwhile, connection instability between the fixator body 1 and the mouth of the patient without teeth can be prevented.

The working principle is as follows: when the mouth is opened in the inspection, as shown in fig. 5, the advice patient opens the mouth to the biggest angle as far as possible, then the ring 3 of taking, make that the less one of positioning plate body 1 diameter put into the mouth down, the card is on incisor about the card, in order to reach fixed effect, incisor's distance about also can recording simultaneously, this structure wholly adopts medical PP plastics, nontoxic safety, do not influence magnetic resonance equipment's work simultaneously, in long-time testing process, it is fixed to open the mouth to the patient, reduce mouth muscle fatigue, overall structure is simple, no disinfection dead angle, use after being convenient for disinfect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
