Description

Improvement of hand tools with molar teeth as resistance points

This creation is about an oral expansion tool, especially a hand tool that uses molars as resistance points.

For patients whose mouth opening angle is limited, to perform mouth opening exercises, clean their mouths, or perform medical actions on their mouths, the assistance of an oral expansion device is generally required.

Conventional oral expansion devices generally use the upper and lower incisors and canines of an oral cavity as resistance points. Therefore, in the process of opening an oral cavity, the incisors and canines will bear considerable force. If not handled properly, its front teeth or canine teeth are likely to be damaged.

In addition, because the conventional oral expansion device directly extends the device into the patient's mouth and directly abuts the molar, this will cause a friction feeling between the patient's molar and the oral expansion device and feel uncomfortable, and hygiene problems To be considered.

In addition, the conventional oral dilation device does not have any scale or structure for patient records to suit their own scale, so when the patient is used for the next time, he must spend another time to re-measure the optimal expansion Angle, very inconvenient.

Therefore, how to solve the above-mentioned problems and deficiencies in practice is the one where creators of this creation and related manufacturers engaged in this industry are desperate to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main purpose of this creation is to provide a hand tool improvement that uses the molars as the resistance point to greatly improve the comfort and cleanliness of use.

The secondary purpose of this creation is to provide a hand tool improvement that uses the molar as the resistance point by adjusting the required angle according to the needs.

The secondary purpose of this creation is to provide a hand tool improvement that uses the molars as resistance points to greatly improve the ease of use.

In order to achieve the above purpose, the present invention provides an improvement of a hand tool with a molar tooth as a point of resistance. It includes a grip unit, a pivot unit, an expansion unit and a clean sheath. The grip unit has a first end And a second end, the first end is for a user to hold, the pivoting unit is correspondingly pivotally connected to the second end, the two ends of the expansion unit respectively form an abutting end and a connecting end, The abutting end corresponds to a plurality of molars that abut a user, the connecting end corresponds to pivotally connect to the pivoting unit, and the cleaning sheath corresponds to the expansion unit.

Through the design of this structure, the clean sheath is fitted on the expansion unit correspondingly, which can improve the discomfort and discomfort of the user when the abutment end of the expansion unit directly abuts the molar Hygiene problems, which greatly improve the comfort and cleanliness of use.

In addition, since the grip unit and the expansion unit are on the same side as the pivot unit, the user can penetrate the expansion unit into the oral cavity and hold the After the connection end abuts the molar, the first expansion arm and the second expansion arm of the expansion unit are separated by operating a first grip portion and a second grip portion of the grip unit , So as to expand the mouth to achieve the effect of self-operation.

Furthermore, the improved manual tool further has an expansion angle measuring unit, and a plurality of scales are formed on the surface of the expansion angle measuring unit. These scales are for users to adjust themselves. Scale to achieve the most comfortable state when opening the mouth and record its scale.

The above-mentioned objects, structural and functional characteristics of this creation will be explained based on the preferred embodiments of the attached drawings.

Please refer to Figures 1A to 3, which are drawings for the creation of a hand tool with a molar tooth as a resistance point. As shown in the figure, an improvement of a hand tool 2 with a molar tooth as a resistance point includes a grip unit 20 , A pivoting unit 23, an expansion unit 24 and a clean sheath 25, the holding unit 20 further has a first holding portion 202 and a second holding portion 203, the first and second holding portions 202 , 203 each have a first end 200 and a second end 201, the first end 200 is for a user 6 to facilitate the holding operation, in addition, the first and second holding portions 202 of the holding unit 20, 203 is also correspondingly provided with a grip 3, which is formed with a plurality of grooves 30 corresponding to the finger arc shape of the user 6 for the user 6 to hold firmly and comfortably.

The pivoting unit 23 is correspondingly pivotally connected to the second end 201 of the gripping unit 20. Further description, a first connecting member 21 is further provided between the pivoting unit 23 and the first gripping portion 202 And a second connecting member 22 is further provided between the pivoting unit 23 and the second gripping portion 203, and the first and second connecting members 21, 22 correspond to the pivoting unit 23 in a pivotable manner To drive the office The first and second grips 202 and 203 are described.

Two ends of the expansion unit 24 form a contact end 242 and a connection end 243, further illustrating that the expansion unit 24 further has a first expansion arm 240 and a second expansion arm 241, the abutment The end 242 further has a first abutting portion 242a and a second abutting portion 242b, the first expansion arm 240 is connected to the first abutment portion 242a, and the second expansion arm 241 is connected to the second abutment portion 242b, the first and second expansion arms 240 and 241 are correspondingly opened or closed, and the first and second abutment portions 242a and 242b respectively abut a plurality of upper molars 60 and a plurality of lower teeth of the user 6 For the molar 60, the expansion unit 24 is pivotally connected to the pivot unit 23 through the connecting end 243.

The cleaning sheath 25 further forms a closed end 250 and an open end 251 and defines a set space 252 together. The cleaning sheath 25 is correspondingly sheathed to cover the expansion unit 24. Specifically, the expansion unit 24, the first and second expansion arms 240, 241 and the first and second abutment portions 242a, 242b are correspondingly accommodated in the sheathing space 252 of the clean sheath 25, so that the first and second expansion arms 240 , 241 and the first and second contact portions 242a, 242b are completely covered by the cleaning sheath 25, and the material of the cleaning sheath 25 may be made of plastic or other polymer materials.

Another technical feature of this creation is that the grip unit 20 and the expansion unit 24 are on the same side as the pivot unit 23.
