Technical Field

The invention relates to the technical field of medical instruments, in particular to an oral cavity supporting device for minimally invasive apical excision.

Background

The root tip resection is mainly aimed at chronic periapical periodontitis with a large inflammatory destruction range of the root tip. In this case, the sinus cannot be cured by the modern root canal treatment technology, and the curative effect is unsatisfactory. Microscopic apical surgery is required to retain the affected tooth. Soft tissue flap turning, bone removal, pathological tip exposure, tissue and marrow cavity cleaning around the tip, pathological tip resection and root canal system sealing at the tip with special material under microscope. Finally, the lesion around the root tip is healed, and the affected teeth are retained. When the root tip excision is performed, the lips of a patient need to be turned up, so that the gum of the patient is directly exposed, and the surgical operation of a doctor is facilitated. The lip turning-up operation of the prior art is that the lip of a patient is turned up by holding a dial plate by medical staff and is propped up the lip for a long time, so that the operation is very troublesome, and the medical staff can feel very fatigue by keeping a fixed posture for a long time.

Disclosure of Invention

The invention aims to solve the defect that in the prior art, the lips of a patient need to be manually turned up by medical staff and then supported for a long time, and provides an oral cavity supporting device for minimally invasive apical resection.

In order to achieve the purpose, the invention adopts the following technical scheme:

an oral cavity supporting device for minimally invasive apical resection is designed, and comprises a fixed column, wherein a notch is formed in the bottom end of the fixed column, an arc shifting piece is inserted into the notch, the arc shifting piece is fixedly installed on the fixed column through a screw, the top end of the fixed column is fixedly connected with a first fixed plate, two sides of the upper surface of the first fixed plate are fixedly provided with a first threaded column, a second fixed plate is arranged right above the first fixed plate, the top end of the first threaded column extends upwards until penetrating through the second fixed plate, a nut is in threaded installation on a column body of the first threaded column positioned above the second fixed plate, a second threaded column is in threaded installation on the second fixed plate between the two first threaded columns, the bottom end of the second threaded column props against the upper surface of the first fixed plate, and a rotary table is fixedly installed at the top end of the second threaded column, the cover is equipped with a spring on the second screw thread post between second fixed plate and the first fixed plate, just fixed connection is on fixed plate, first fixed plate respectively at the both ends of spring, fixed mounting has universal knee on the side of second fixed plate, the first flange of other end fixedly connected with of universal knee, first flange fixed mounting is on supporting mechanism.

Preferably, the supporting mechanism comprises a second connecting disc, a rotating shaft, a transverse plate, a telescopic rod and a chassis, the telescopic rod is fixedly mounted on the chassis, the transverse plate is fixedly mounted at the top end of the telescopic rod, the rotating shaft is fixedly mounted on the lower surface of the transverse plate, the second connecting disc is fixedly mounted at the bottom end of the rotating shaft, and the second connecting disc and the first connecting disc are fixedly mounted together through a plurality of bolts and nuts.

Preferably, the surface of the turntable is circumferentially provided with anti-skid grains.

Preferably, the arc-shaped shifting plate is a disposable plastic shifting plate.

The oral cavity supporting device for minimally invasive apical excision provided by the invention has the beneficial effects that: by arranging the arc-shaped poking plate with the adjustable height angle, when a doctor performs root apex excision on the oral cavity of a patient, the lip of the patient is lifted and turned over by the arc-shaped poking plate and is propped up for a long time, and the lip does not need to be manually turned over by the doctor, so that the doctor can operate more conveniently; the arc-shaped shifting plate which can be replaced is arranged, so that cross infection can be avoided.
