Description

Expansion support for department of stomatology

Technical Field

The utility model relates to an oral cavity science and technology field, more specifically say, relate to an expansion eyelidretractor for department of stomatology.

Background

When a patient has difficulty in breathing or does not have a clear mind and needs to wash the stomach, a medical instrument for opening the oral cavity is needed.

The patent document with the existing publication number of CN216060784U provides an expansion support device for department of stomatology, the device is clamped with the surfaces of two arc-shaped blocks through a set groove block, then a pressing block at one end of a first rotating rod and one end of a second rotating rod are pressed, the two groove blocks are pushed in the opposite direction, so that the angles of the two arc-shaped blocks are changed, the mouth size of different people is adapted by adjusting the angle between the two arc-shaped blocks when the mouth opener is used for different people, and the adaptability of the mouth opener is improved.

Although the device has more beneficial effects, the following problems still exist: the device can only adjust the longitudinal size of the mouth and can not adjust the transverse size of the mouth, so that the device can not open the mouth of a patient to a reasonable size in the practical application process, and corresponding medical work is inconvenient to perform. In view of this, we propose an expanding support for use in the stomatology department.

SUMMERY OF THE UTILITY MODEL

1. Technical problem to be solved

An object of the utility model is to provide an expansion eyelidretractor for department of stomatology to solve the problem that proposes among the above-mentioned background art.

2. Technical scheme

An expansion support for an oral cavity, comprising a support frame, further comprising: the limiting holes are formed in the supporting frame; the limiting rods limit sliding in the limiting holes; the expansion plates are fixedly connected with the limiting rod; the adjusting component can regulate and control the position of the expansion plate.

As an alternative of the technical solution of the present application, the adjusting assembly includes: the connecting lugs are fixedly connected with the limiting rod; the adjusting rod is connected with the supporting frame in a sliding mode and is connected with the connecting lug in a sliding mode; the threaded rod is rotationally connected with the supporting frame, two-way threads are formed in the threaded rod, and the threaded rod is in threaded connection with the adjusting rod.

As an alternative of this application technical scheme, fixedly connected with slide rail on the braced frame, the spread groove has been seted up to the regulation pole tip, spread groove and slide rail sliding connection.

As an alternative of this application technical scheme, braced frame one side fixedly connected with handle, the handle rotates with the threaded rod to be connected, threaded rod one end fixedly connected with rotates the handle.

As an alternative of the technical solution of the present application, the lower portion of the expansion board is disposed in a U-shape.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages of:

1. this application file is through having seted up a plurality of spacing holes on braced frame, restricts the removal of gag lever post for a plurality of gag lever posts can expand patient's lip to the direction of difference through driving a plurality of expansion boards, make it can satisfy more operational environment and work demands, and then solved original device and only can adjust the longitudinal dimension of mouth, can not adjust the transverse dimension of mouth, lead to the relatively poor problem of this device practicality.

2. This application file utilizes the screw pole to drive the regulation pole, and then makes this device can utilize threaded connection's auto-lock characteristic, adjusts wantonly the interval between the regulation pole, and then makes the interval between the expansion board to adjust, not only can the person of facilitating the use send the expansion board into patient's mouth, can also adjust the expansion size according to patient's mouth size, increases the application scope of this device.

Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

an expansion support for stomatology comprises a support frame 1, and further comprises: the limiting holes 2 are formed in the supporting frame 1; the limiting rods 3 are limited to slide in the limiting holes 2; the expansion plates 4 are fixedly connected with the limiting rod 3; the adjusting component 5, the adjusting component 5 can regulate and control the position of the expansion board 4. Through the technical means, the expansion size of the device can be conveniently adjusted by a user.

Specifically, the adjustment assembly 5 includes: the connecting lugs 6 are fixedly connected with the limiting rod 3; the adjusting rod 7 is connected with the supporting frame 1 in a sliding mode, and the adjusting rod 7 is connected with the connecting lug 6 in a sliding mode; threaded rod 8, threaded rod 8 and braced frame 1 rotate to be connected, have seted up two-way screw thread on the threaded rod 8, threaded rod 8 with adjust 7 threaded connection of pole. By this means, the user can adjust the position of the adjustment lever 7.

Furthermore, a sliding rail 9 is fixedly connected to the supporting frame 1, a connecting groove 10 is formed in the end portion of the adjusting rod 7, and the connecting groove 10 is slidably connected with the sliding rail 9.

Furthermore, a handle 11 is fixedly connected to one side of the supporting frame 1, the handle 11 is rotatably connected to the threaded rod 8, and a rotating handle 12 is fixedly connected to one end of the threaded rod 8.

Further, the lower part of the expansion board 4 is arranged in a U shape. By the technical means, the expansion plate 4 can effectively hang the lips of the patient.

The working principle is as follows: when the device is used, a user takes the device up through a handle, the expansion plate 4 extends into the oral cavity of a patient, the rotating handle 12 is rotated, the rotating handle 12 can drive the threaded rod 8 to rotate, the threaded rod 8 can push the adjusting rod 7 to two sides, the adjusting rod 7 can push the limiting rod 3 to two sides through the connecting lug 6, the limiting rod 3 can slide in the limiting hole 2, the limiting rod 3 can drive the expansion plate 4 to move outwards, and the U-shaped part at the lower part of the expansion plate 4 can hang the lips of the patient to expand outwards to open the oral cavity of the patient; because threaded connection has the function of auto-lock for the user can be according to the interval between patient's mouth size control expansion plate 4, and then adapts to different crowds.
