Description

Technical Field

[0001] The invention relates to the technical field of oral surgery, in particular to a supporting device for oral surgery. Background Art

[0002] During an examination or operation, an oral surgeon needs to use an oral retractor to open the patient's mouth for maxillofacial surgery. However, the existing oral retractors used for oral and maxillofacial surgery have a relatively simple function of only opening the oral cavity, but are unable to open the cheek side of the oral cavity.

[0003] In order to solve this technical problem, technicians have developed a new type of oral retractor, such as a special oral inspection device in the Chinese patent CN110367918B authorization announcement, which includes a main block and a movable block, wherein a connecting hose is movably connected between the main block and the movable block, a first opening is provided inside the main block, and a second opening is provided inside the movable block, which is located on the side of the first opening. When the special oral inspection device is used to retract the patient's oral cavity, one end of the movable rod is placed in the patient's oral cavity, and the movable block is pulled toward the end away from the main block, so that the connecting block at one end of the movable block moves to the right until the movable clamping block moves to the clamping slot position, and the movable clamping block is clamped with the inner wall of one side of the clamping slot, and at the same time, the first connecting rope at one end of the connecting head pulls the protrusion on one side of the movable rod, so that the two movable rods are retracted to a certain angle, so that the movable rod can retract the patient's oral cavity, which is convenient for performing the patient's oral inspection operation.

[0004] However, the above-mentioned oral retractors still have many deficiencies in actual use, such as complex structural design, inconvenient use, and easy obstruction of the doctor's vision. Summary of the invention

[0005] The object of the present invention is to provide a supporting device for oral surgery, which overcomes the deficiencies of the aforementioned prior art, has a simple structural design, is easy to use, does not block the doctor's field of vision, and can be easily adjusted.

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] A support device for oral surgery, comprising an upper bite plate, a lower bite plate and a side support mechanism, wherein:

[0008] The upper bite plate is an upper arc-shaped structure, and the lower bite plate is a lower arc-shaped structure symmetrical to the upper bite plate. One end of the upper bite plate and the lower bite plate are connected by a side support mechanism, and the other end is connected by another side support mechanism or by a connecting rod.

[0009] The side support mechanism includes a support rod, a sleeve, an insertion rod and a side support plate, a support rod is fixed between the corresponding ends of the upper bite plate and the lower bite plate, a sleeve is movably sleeved on the outer wall of the support rod, the upper end face and the lower end face of the sleeve are both provided with an insertion rod, and the side support plate is fixed to the side wall of the sleeve; the lower end face of one end of the upper bite plate is arranged in a circular array with a circle of upper plug holes matching with the insertion rod, and the upper end face of one end of the lower bite plate is arranged in a circular array with a circle of lower plug holes matching with the insertion rod;

[0010] When the device is in use, the patient bites the upper and lower bite plates with his teeth to open the mouth. The upper and lower bite plates have a certain degree of elasticity. The side support plates are pushed into the mouth using cotton swabs or round-head tweezers and other tools to open the jaws. After the position of the side support plates is adjusted, the side support plates are moved down using cotton swabs so that the insertion rods are inserted into the nearest lower insertion holes to fix the position of the side support plates. The structural design is simple and easy to use. After the position of the side support plates is fixed, the entire device opens the mouth and jaws well without blocking the doctor's line of sight, making it easy to observe the oral condition. The side support mechanism can be installed on both sides or on only one side. When only one side is installed, it is suitable for observing the situation on the left or right side of the mouth. The device can be turned upside down to change the direction in which it can be opened.

[0011] Furthermore, the side support plate has an arc-shaped structure, and the side support plate includes a first plate body and a second plate body.

This design method is conducive to adjusting the length of the side support plate according to the size of the patient's oral and maxillofacial area, which is generally adjusted by the doctor based on experience before the device is used.

[0014] Furthermore, an adjustment hole is provided on the second plate body. After adjusting the position of the second plate body, the adjustment hole can be moved by a cotton swab or other tool to rotate the second plate body upward or downward by a certain angle, thereby improving the distraction effect of the side support plate on the maxillofacial surface.

[0015] Furthermore, the lower edge of the buffer long hole located at the top is in a continuous arc shape, and the upper edge of the buffer long hole located at the bottom is in a continuous arc shape, which plays a buffering role in the process of pulling the second plate body shaft to move.

[0016] Furthermore, LED lamp beads are arranged on the first plate body or the second plate body to facilitate the doctor to observe the internal conditions of the oral cavity.

[0017] Furthermore, outer edges of the first plate body and the second plate body are smooth.

[0018] Furthermore, the sum of twice the length of the insertion rod and the length of the sleeve is less than or equal to the length of the support rod.

[0019] Furthermore, an upper bite groove is formed on the upper end surface of the upper bite plate, and a lower bite groove is formed on the lower end surface of the lower bite plate.
