The mouth-opening difficulty exerciser has the advantages that the mouth-opening difficulty exerciser can assist a patient in mouth-opening exercise according to an exercising mode meeting clinic requirements, conversion from a mode that the patient must pay attention to and exert himself or herself in mouth-opening difficulty exercising to a mode of automatically and scientifically exercising according to medical advice, progress is made step by step from easiness to difficulty, temporal-mandibular joint muscles are improved effectively, and quick and effective exercising effect is realized finally. The mouth-opening difficulty exerciser is convenient and easy to use and simple to operate.
Description
Technical field
The present invention relates to rehabilitation medical instrument, especially relate to for patient's difficulty in opening mouth exerciser.
Background technology
The ankylosis of temporo-mandibular joint of difficulty in opening mouth clinically mainly owing to causing nasopharyngeal carcinoma and oral cancer radiotherapy, organic disease etc.Show as that remporomandibular joint when dehiscing is felt nervous, pain, mouth opening reduce, even gnathospasma, cause patients diet's difficulty.The patient of ankylosis of temporo-mandibular joint its periarticular muscle, ligament etc. are in bonding useless state for a long time, functional activity reduces greatly, suitable and reconditioning and treatment and nursing measure effectively can promote local blood circulation targetedly, promote disappearing of the edema that causes of wound or hematoma, recover the normal physiological function that patient dehisces in time.Have data to show, after Patients Treated by Radiotherapy, difficulty in opening mouth mostly occurs in 1-2, and incidence rate reduces afterwards, but functional exercise of not carrying out dehiscing still can occur limitation of mouth opening.
Tradition mainly contains the exercise of dehiscing of patient: 1, dehisced to take exercise by patient oneself without aid; The method uninteresting being difficult to adheres to, without DeGrain under medical professional.2, simple and crude utensil auxiliary exercise is adopted; Such as cork method, wet towel method etc.Said method cannot, according to the requirement of medical personnel, take gradual and orderly approach to take exercise, and is still subject to the random nonstandard exercise of patient self, finally causes rehabilitation efficacy not obvious.Therefore, the difficulty in opening mouth caused by Patients Treated by Radiotherapy still lacks good Therapeutic Method, focuses on prevention nursing and takes exercise.
Summary of the invention
The object of the invention is to provide a kind of difficulty in opening mouth exerciser, reaches the active, effective, controlled that patient dehisces to take exercise, from the easier to the more advanced progressively improves, finally reach train on fast and effectively.
For achieving the above object, the present invention takes following technical proposals:
Difficulty in opening mouth exerciser of the present invention, comprise housing, described housing tip is extended to side lower teeth pallet, push rod and the push rod driving mechanism of arcuate structure is provided with in housing, described push rod top is extended outside housing from case top window sliding, and push rod top is fixed with upper teeth pallet.
Described push rod is hollow structure, described upper teeth pallet and described lower teeth pallet extended in the same way, push rod side surface is provided with graduated scale; Described push rod driving mechanism comprises the nut being arranged on push rod inner chamber bottom, and described nut is connected with screw rod transmission by threaded engagement, and described screw mandrel is by speed reducing gear pair and be in transmission connection by monolithic processor controlled motor output shaft; In housing, be provided with the accumulator providing electric energy to described motor and single-chip microcomputer, described single-chip microcomputer regulates button to be positioned at housing outer surface.
Gathering sill and push rod position-detection sensor, push rod thrust measurement sensor that radian and push rod radian adapt is provided with in described housing, described push rod is slidably arranged in described gathering sill, and the signal output part of described push rod position-detection sensor, push rod thrust measurement sensor is connected with described single-chip microcomputer signal input part.
The invention has the advantages that assisting patients carries out dehiscing to take exercise according to the exercise mode meeting clinical requirement, realize patient's difficulty in opening mouth to take exercise and must diligently, firmly change performing physical exercise according to doctor's advice science automatically into by self, from the easier to the more advanced progressively improve, reach effective improvement of remporomandibular joint muscle, finally reach train on fast and effectively.The present invention is simultaneously easy to use light, simple to operate.

Detailed description of the invention
As Figure 1-4, difficulty in opening mouth exerciser of the present invention, comprise the housing fastened by upper shell 1 and lower house 2, be fixed on the lower teeth pallet 3 that lower house 2 top extends to side, in housing, be provided with push rod 4 and the push rod driving mechanism of arcuate structure; Push rod 4 is hollow structure and is slidably mounted in the radian gathering sill 5 in housing, push rod 4 top is extended outside housing from case top window sliding, push rod 4 top is fixed with upper teeth pallet 6, upper teeth pallet 6 is extended in the same way with lower teeth pallet 3, and push rod 4 side surface is provided with the graduated scale 7 stretching out shell length for measuring push rod 4; Push rod driving mechanism comprises the nut 8 being fixed on push rod 4 inner chamber bottom kidney-shaped hole slot 17 by positioning rotating shaft 15, this nut 8 is in transmission connection by threaded engagement and screw mandrel 9, and screw mandrel 9 is in transmission connection by speed reducing gear pair 10 and motor 12 output shaft controlled by single-chip microcomputer 11; The accumulator 13 that electric energy is provided to this motor 12 and single-chip microcomputer 11 is provided with in housing, and push rod position-detection sensor, push rod thrust measurement sensor, the signal output part of push rod position-detection sensor, push rod thrust measurement sensor is connected with single-chip microcomputer 11 signal input part, and the regulating and controlling button 14 of single-chip microcomputer 11 is positioned at the outer surface of upper shell 1.
Operation principle of the present invention is summarized as follows:
When pressing out/stop button 16, motor 12 rotates, motor 12 drives screw mandrel 9 to rotate by speed reducing gear pair 10, actuating sleeve establishes nut 8 thereon along screw mandrel 9 axial linear movement, thus drive the push rod 4 of arcuate structure to move upward along radian gathering sill 5, opened with certain angle between the lower teeth pallet 3 making upper teeth pallet 6 and be fixed on lower house 2 top.When push rod 4 moves along radian gathering sill 5, change with the relative position of screw mandrel 9, to be sheathed on screw mandrel 9 due to nut 8 and can only along screw mandrel 9 axial linear movement, the positioning rotating shaft 15 therefore on nut 8 simultaneously in the kidney-shaped hole slot 17 of push rod 4 inner chamber bottom along its length straight-line displacement to adapt to the change in location of push rod 4.
Push rod position-detection sensor is used for the shift position of push rod 4,
When push rod 4 move up and down position arrive setting position time, push rod position-detection sensor sends signal and controls motor 12 by single-chip microcomputer 11 and stop operating, and reverse according to setting program reed time controll motor 12, motor 12 drives screw mandrel 9 to rotate backward by speed reducing gear pair 10, thus makes the nut 8 be set on screw mandrel 9 drive push rod 4 to retract.When push rod 4 is retracted into initial position, push rod position-detection sensor sends signal and controls motor 12 by single-chip microcomputer 11 and stop operating.
Patient's exercise mode of dehiscing is realized by the program of single-chip microcomputer 11, comprise upper and lower dental tray 6,3 open with the size of the speed of closing motion, opening dimension, open thrust size and open and closed after time etc. of stop motion.
