Description
Technical field
The present invention relates to rehabilitation medical instrument, be especially for patient's difficulty in opening mouth exerciser.
Background technology
Difficulty in opening mouth is clinically mainly due to the ankylosis of temporo-mandibular joint causing nasopharyngeal carcinoma and carcinoma of mouth radiotherapy, organic disease etc..When showing as dehiscing, remporomandibular joint is felt nervous, pain, mouth opening reduce, and even lockjaws, and causes patients diet's difficulty.The patient of ankylosis of temporo-mandibular joint its periarticular muscle, ligament etc. are chronically at bonding useless state, functional activity is substantially reduced, properly and targetedly local blood circulation can be effectively promoted in reconditioning and treatment and nursing measure, promote disappearing of the oedema that causes of wound or hemotoncus, recover the normal physiological function that patient dehisces in time.Having data to show, after Patients Treated by Radiotherapy, difficulty in opening mouth mostly occurs in 1-2, and incidence reduces afterwards, but the functional training that do not carries out dehiscing still may occur in which limitation of mouth opening.
Patient is dehisced to practise mainly to have by tradition: 1, dehisce exercise by patient oneself without aid；The method is adhered to by uninteresting being difficult to, without DeGrain under medical professional.2, simple and crude utensil auxiliary exercise is used；Such as cork method, wet towel method etc..Said method cannot take gradual and orderly approach to take exercise according to the requirement of medical personnel, nevertheless suffers from the random nonstandard exercise of patient self, ultimately results in rehabilitation efficacy inconspicuous.Therefore, the difficulty in opening mouth caused by Patients Treated by Radiotherapy still lacks preferable methods for the treatment of, focuses on prevention nursing and takes exercise.
Summary of the invention
Present invention aim at providing a kind of difficulty in opening mouth exerciser, reach active that patient dehisces to take exercise, effective, controlled, from the easier to the more advanced step up, be finally reached 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, including housing, described housing tip is extended to side lower teeth pallet, push rod and the push rod drive mechanism of arcuate structure it is provided with in housing, described push rod top is outside case top window sliding extends housing, and push rod top is fixed with upper teeth pallet.
Described push rod is hollow structure, and described upper teeth pallet is the most extended with described lower teeth pallet, and push rod side surface is provided with graduated scale；Described push rod drive mechanism includes 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 in transmission connection with by monolithic processor controlled motor output shaft by speed reducing gear pair；Arranging oriented described motor and the battery of single-chip microcomputer offer electric energy in housing, described single-chip microcomputer regulation button is positioned at housing outer surface.
Gathering sill and push rod position-detection sensor, push rod thrust measurement sensor that radian adapts it is provided with push rod radian in described housing, described push rod is slidably arranged in described gathering sill, and described push rod position-detection sensor, the signal output part of push rod thrust measurement sensor are connected with described single-chip microcomputer signal input part.
The invention has the advantages that auxiliary patient carries out dehiscing to take exercise according to the exercise mode meeting clinical requirement, realize the exercise of patient's difficulty in opening mouth and must diligently, be firmly changed into performing physical exercise according to doctor's advice science automatically by self, from the easier to the more advanced step up, reach being effectively improved of remporomandibular joint muscle, be finally reached train on fast and effectively.The present invention is easy to use light, simple to operate simultaneously.

Detailed description of the invention
As Figure 1-4, difficulty in opening mouth exerciser of the present invention, including the housing fastened by upper shell 1 and lower house 2, is fixed on the lower teeth pallet 3 that lower house 2 top extends to side, is provided with push rod 4 and the push rod drive mechanism of arcuate structure in housing；In push rod 4 is hollow structure the radian gathering sill 5 that is slidably mounted in housing, push rod 4 top is outside case top window sliding extends housing, push rod 4 top is fixed with upper teeth pallet 6, upper teeth pallet 6 is the most extended 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 drive mechanism includes 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 with screw mandrel 9 by threaded engagement, and screw mandrel 9 is in transmission connection with motor 12 output shaft controlled by single-chip microcomputer 11 by speed reducing gear pair 10；This motor 12 oriented is set in housing and single-chip microcomputer 11 provides the battery 13 of electric energy, and push rod position-detection sensor, push rod thrust measurement sensor, push rod position-detection sensor, the signal output part of push rod thrust measurement sensor are connected with single-chip microcomputer 11 signal input part, and the control and regulation 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 is located at 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 so that opened with certain angle between upper teeth pallet 6 and the lower teeth pallet 3 being fixed on lower house 2 top.Push rod 4 along radian gathering sill 5 move time, change with the relative position of screw mandrel 9, due to nut 8 be sheathed on screw mandrel 9 and can only along screw mandrel 9 axial linear movement, therefore the positioning rotating shaft 15 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 moving up and down the position that position arrives setting of push rod 4, push rod position-detection sensor sends signal and is controlled motor 12 stopped operating by single-chip microcomputer 11, and invert according to setting program reed time controll motor 12, motor 12 drives screw mandrel 9 to rotate backward, so that the nut 8 being set on screw mandrel 9 drives push rod 4 to retract by speed reducing gear pair 10.When push rod 4 is retracted into initial position, push rod position-detection sensor sends signal and is controlled motor 12 stopped operating by single-chip microcomputer 11.
Patient's exercise mode of dehiscing is realized by the program of single-chip microcomputer 11, including upper and lower dental tray 6,3 open the speed with closing motion, the size of opening dimension, open thrust size and open with Guan Bi after time etc. of stop motion.
