Embodiment 1

[0027] Example 1 as Figure 1-5 As shown, an electric multifunctional oral mouth opener according to an embodiment of the present invention includes a control part 1 and a movable part housing 10 detachably connected to the control part 1 through a fixed rod 24; the number of fixed rods 24 can be determined according to The actual needs and models are set to 3-6, and the fixing rod 24 can be directly inserted or snap-fitted, which is convenient for disassembly and maintenance.

[0028] The control unit 1 includes a battery 4 arranged at the tail of the control unit 1 , a motor 2 arranged at the upper end of the control unit 1 , a reducer 3 connected to the motor 2 , and a connection connected to the reducer 3 . Part 5, the switch button 7, the upper movement button 8 and the lower movement button 9 arranged on the casing of the control part 1; the battery 4 and the motor 2, the switch button 7, the upper movement button 8 and the lower movement button 9 All are electrically c...

Embodiment 2

[0030] Embodiment 2 On the basis of Embodiment 1, the connecting member 5 is pinned to the pinion 13 and fixed by a connecting pin 14 . The connecting piece 5 is connected to the pinion 13 through the connecting pin 14, and is transmitted to the bull gear 12, and then controls the two-way movement of the rack 11, controls the movement of the lower support plate 19, and then controls the relative movement and state of the oral cavity.

Embodiment 3

[0031] Embodiment 3 On the basis of Embodiment 1, stoppers 19 are provided at both ends of the tooth side of the rack 11 . The stopper 19 is used to control the movement range of the rack 11 and further control the relative distance between the upper support plate 18 and the lower support plate 19 .

Abstract

The invention discloses an electric multifunctional oral cavity mouth gag. The mouth gag comprises a control part and a movable part shell detachably connected with the control part through a fixing rod. The mouth gag has multiple functions, can simultaneously realize active and passive opening-closing continuous movement of an oral cavity and accurate maintenance of the opening degree, and has multiple purposes of auxiliary opening treatment, training rehabilitation, auxiliary maxillofacial repair design and the like; the operation is simple, continuous movement, positioning movement and fixed maintenance of oral cavity supporting plates are achieved only by operating a button switch with one hand, the operation time is shortened, and the result precision is improved; and the mouth gag ishigh in universality, the supporting plates of different sizes or structures can be flexibly replaced according to the characteristics of patient groups, the mouth gag can be used for patients of different groups, and meanwhile the operability of the mouth gag is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electric multifunctional oral mouth opener. Background technique [0002] In the process of treating oral diseases, mouth gags are commonly used to assist patients in treatment. In addition, in the aspects of oral rehabilitation training, maxillofacial repair design, etc., the mouth gag is also an important and even indispensable medical auxiliary device. [0003] The existing mouth gag technology mainly uses a simple mechanical structure or mechanism to move the upper and lower jaws of the oral cavity to achieve active or passive opening of the oral cavity. Although there are many kinds of mouth mouth devices in clinic and on the market, they all have one or more of the following disadvantages: simple structure, difficult to quantify mouth opening, and cannot be used for further research on maxillofacial restoration design, rehabilitation training, etc.; manual con...
