Description

Technical Field

[0001] The invention relates to the technical field of oral medical instruments, and in particular to an opener for oral disease inspection and treatment. Background Art

[0002] Oral medicine is an important clinical discipline in stomatology. It mainly studies and treats various common and frequent oral diseases. Oral medicine aims to preserve the original organs and maintain their original functions, and is committed to restoring the oral health of patients. Oral medicine treats a wide range of diseases, including but not limited to: hard tissue diseases, pulp diseases, periapical diseases, periodontal tissue diseases, and oral mucosal diseases.

[0003] During the examination and treatment of oral medicine, it is usually necessary to use an opener to help open the human mouth so that medical staff can clearly observe the internal situation of the human mouth, or perform oral disease rehabilitation operations in the mouth. However, in the current clinical oral treatment process, there are the following problems:

[0004] First, the current mouth openers are difficult to operate, and in order to ensure that the patient's mouth is opened, most of the mouth openers will block the human oral field of vision to a certain extent, affecting the medical staff's observation of the inside of the oral cavity, and even affecting the medical staff's medical operations inside the human oral cavity;

[0005] Secondly, the current mouth opener is only for opening the human oral cavity, and cannot restrict the human tongue. During the operation, when the surgical instrument contacts the mucosa or tissue inside the human oral cavity, some patients' tongues will move uncontrollably, and some patients have thick tongue coating. Whether it is a patient with uncontrollable tongue movement or a patient with thick tongue coating, they are prone to accidental injury by oral treatment instruments during oral treatment.

[0006] In summary, the oral retractors of the prior art have the following problems: the retractors of the prior art are prone to block the oral visual field and hinder oral treatment operations.

[0007] Therefore, the present invention discloses an opener for oral disease inspection and treatment. Summary of the invention

[0008] In order to solve the drawbacks of the prior art, the present invention discloses an oral opening device for oral disease inspection and treatment, comprising: a box body;

[0009] The box is an open rectangular parallelepiped, with symmetrical through holes at the front end of the box for rotationally connecting the rotating rods, and a straight rod connected to the fixed frame at the rear end of the box;

[0010] A threaded rod is arranged at one end of the rotating rod, and the upper part of the other end is hinged to the upper brace and the lower part is welded to the lower brace; a disc is arranged at the other end of the threaded rod, and a threaded sleeve is arranged on the threaded rod to connect the push rod; a circular hole is arranged in the middle of the circular disc to connect the L-shaped plate, and a cylinder is arranged in the circular hole; a sliding groove is arranged at the upper end of the straight rod composed of the screw rod and the rotating rod to install the push rod;

[0011] The rear end of the push rod abuts against the screw sleeve, and the front end of the push rod is a triangular plate, and the upper end of the triangular plate is slidably connected to the lower end of the upper brace;

[0012] The lower end of the upper brace is provided with a sliding groove for sliding connection with a push rod, and the push rod is driven to move by rotating the screw sleeve, and the push rod drives the upper brace to rotate to open the upper teeth;

[0013] The lower end of the L-shaped plate is symmetrically provided with a round rod mounted on the disc, and a spiral groove is provided on the outer wall of the round rod, and the spiral groove is slidably connected to the cylinder on the disc; the L-shaped plate is symmetrically provided with sliding grooves for slidingly installing the square plate; the upper part of the square plate is symmetrically provided with limiting grooves, and an elastic element is provided in the limiting groove to connect the clamping plate; the side wall of the square plate is provided with an elastic element to connect the L-shaped plate;

[0014] Furthermore, a rack connecting card plate is symmetrically arranged inside the box, and a plurality of helical wedge-shaped gears are arranged on the rack;

[0015] The box body is provided with a straight rod connecting a fixing frame;

[0016] The fixing frame is a concave frame, and a threaded hole is provided on the side wall of the fixing frame to connect the fixing rod, and the fixing frame is clamped and fixed by rotating the fixing rod;

[0017] Furthermore, the square plate is symmetrically provided with limit grooves, and a card plate is arranged in the limit groove; one end of the card plate is an oblique cross-section; the L-shaped plate is driven downward by pressing the square plate, and the pressure on the card plate is released after reaching the specified position, and the card plate is stuck in the adjacent gear of the rack under the action of the elastic element connected thereto, thereby limiting the up and down movement of the card plate and maintaining the open state of the rotating rod; when the card plate needs to be retracted, the square plate is pressed to drive the square plate to slide in the sliding groove on the L-shaped plate, and after the card plate is out of the rack, the square plate is pushed upward to reset the square plate, the L-shaped plate and the rotating rod.

[0018] The beneficial effects of the present invention are:

[0019] The present invention aims at the drawbacks of the open mouth device for oral disease inspection and treatment in the prior art, and discloses an open mouth device for oral disease inspection and treatment, comprising: a box body, a rotating rod, an L-shaped plate, a square plate, a clamping plate, an upper tooth brace, a screw sleeve, and a push rod; a fixing frame is arranged on the box body to fix the open mouth device for oral disease inspection and treatment, a rack is symmetrically arranged at the front of the box body to connect the clamping plate, and through holes are symmetrically opened on the box body to install the rotating rod, a circular hole is opened in the middle of the rear of the rotating rod to connect the L-shaped plate, a lower tooth brace is welded at the lower part of one end of the rotating rod, and an upper tooth brace is hinged at the upper part, and a push rod pushed by the screw sleeve is arranged on the rotating rod to connect the upper tooth brace;

[0020] After inserting the mouth opener for oral disease examination and treatment into the oral cavity, the L-shaped plate is driven downward by pressing the square plate. During the movement, the square plate presses the L-shaped plate downward, and the cylinder at the bottom of the L-shaped plate moves downward. The spiral groove moves downward without being able to rotate. The spiral groove presses the cylinder on the disc to move in the spiral groove, driving the two rotating rods to open synchronously. After opening to a width suitable for the size of the human oral cavity, the lower braces are clamped into the lower teeth of the human body, and the upper braces are clamped on the upper teeth of the human body. The screw sleeve is rotated to drive the push rod to move, and the upper braces are pushed to move to open the human oral cavity.

[0021] In the present invention, the human oral cavity is opened by pressing the square plate to control the opening and closing of the rotating rod, which is simple to operate, and the opening components extending into the human oral cavity are only the rotating rod, the upper braces, and the push rod. The arrangement of the above components fits the teeth or tongue of the human body and does not block the human oral cavity, thereby solving the problem in the prior art that the opening device easily blocks the oral field of view and hinders the oral treatment operation.
