Description

The oral cavity bracing frame

This utility model relates to a kind of oral appliance, mainly is a kind of oral cavity bracing frame.

In the past, in odontotherapy, usually adopted mouth mirror or oral cavity drag hook to realize that tongue and buccal or tongue and lip are isolated.So often cause opereating specification little because tongue and buccal or tongue and lip can not fully be isolated, the visual field is unclear, the extended treatment time, influences that therapeutic effect and patient cross opening of a specified duration and the fatigue that makes facial muscle and joint.

This utility model is in order to overcome above-mentioned deficiency, and provide a kind of oral cavity bracing frame, this oral cavity bracing frame can be realized the abundant isolation of tongue and buccal or tongue and lip to the patient of various degree of lip-rounding sizes in odontotherapy and operating process, broaden one's vision, enlarge opereating specification, provide convenience, both shortened treatment time for operation in medical personnel's mouth, compare health again, can also reduce patient and cross the misery that opening of a specified duration causes.

The purpose of this utility model is achieved through the following technical solutions.This oral cavity bracing frame is characterized in that described bracing frame comprises carriage, support and controller, and two symmetric carriages are connected by the symmetric support of the right and left up and down, and support is provided with the controller of control carriage folding.

This utility model can come further perfect by the following technical programs.Described carriage is the arcuate groove that matches with the oral cavity, but the middle part of groove is the disjunctor of an along continuous straight runs micro-strain, is provided with sawtooth on the inwall on groove both sides.Described support comprises link and reed, and link is triangular in shape, and two ends are provided with slot, and the centre is provided with the connecting rod that connects the control wheel; Reed is straight shape under naturalness, curved after installing, and is connected with link by slot, and two ends are provided with the hook that matches with sawtooth in the bracket slot.Described controller comprises control wheel and spanner, and the control wheel is provided with the reed control shelves of slotted eye, fifth wheel, prominent foot, positioning and control reed; The centre is provided with the bearing pin that matches with connecting rod; Spanner is provided with pin and the spanner locating slot that matches with fifth wheel.Be adhesive with the sterilization soft formation on the outer rim of described carriage.The tongue control strip is provided with the tooth that matches with prominent foot, is connected with the control wheel by slotted eye.

The utility model has the advantages that: by the folding degree of controller control carriage, owing to adopted the arcuate groove that matches with the oral cavity as carriage, adopted the tongue control strip to limit the position of tongue simultaneously, thereby patient to the different degree of lip-roundings and oral cavity size, can enlarge or regulate the opereating specification and the visual field as required, the doctor is easy to operate, and patient magnifies also free and relaxed.
