Description

Tongue Detainer

Technical Field

The utility model relates to the field of tongue depressors, in particular to a tongue shield.

Background technique

When dentists perform resin filling, root canal treatment, tooth preparation and other operations, they often need to use a high-speed rotating turbine handpiece. During the operation of the handpiece, the patient's tongue often swings involuntarily, causing the high-speed turbine handpiece to accidentally injure the tongue. For this reason, doctors generally use a tongue depressor to press the tongue to prevent the tongue from swinging, and also need to insert a saliva suction tube into the patient's mouth to prevent saliva, blood, flushing fluid and other liquids from affecting the surgical field of view.

Therefore, if a tongue depressor is combined with a saliva suction device to form a tongue shield, which has the functions of both, it should be possible to suck liquid while preventing the tongue from swinging. However, the tongue shield needs to press against the patient's tongue, and the saliva suction hole on the tongue shield is pressed against the tongue, and the tongue and other soft tissues will cover the saliva suction hole, making the tongue shield lose its saliva suction function.

Utility Model Content

The utility model aims to provide a tongue shield to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

The technical solutions adopted to solve the above technical problems are:

A tongue shield, comprising:

A handle, the interior of which is provided with a passage connected to the outside world;

A shielding plate is connected to the handle, wherein an inner cavity is provided inside the shielding plate, and the inner cavity is communicated with the channel; an outer edge of the shielding plate is provided with a protruding block protruding outward, and a plurality of saliva suction holes are provided on the periphery of the protrusion, and all the saliva suction holes communicate the inner cavity with the outside world.

The beneficial effects of the utility model are as follows: the channel of the handle is connected to the negative pressure device, and the negative pressure device forms negative pressure in the channel, the inner cavity, and the saliva suction hole. After the doctor holds the handle with his hand, he presses the top wall or the bottom wall of the shielding plate against the patient's tongue to prevent the patient's tongue from swinging, and the protrusion located at the outer edge of the shielding plate has a saliva suction hole that can absorb saliva, blood, flushing fluid and other liquids to optimize the surgical field of view; even if the protrusion is covered by the soft tissue of the patient's oral cavity, the protrusion protrudes out of the shielding plate, the protrusion can lift the soft tissue, and the deformation capacity of the soft tissue is limited, and the soft tissue will not be completely wrapped around the outside of the protrusion, so a gap is formed between the soft tissue and the shielding plate, so that the saliva suction holes on the outer periphery of the protrusion that are not covered by the soft tissue can absorb liquid from the gap, thereby maintaining the saliva suction function of the tongue shield.

As a further improvement of the above technical solution, with the position of the handle relative to the shielding plate as the relative rear direction, the width of the horizontal cross-section of the shielding plate gradually decreases from front to back.

The width of the horizontal cross-section of the shielding plate gradually decreases from front to back, making the shielding plate a trapezoidal structure with a larger front and a smaller back, so as to expand the area of the top and bottom walls of the shielding plate, thereby increasing the area of the shielding plate pressing against the patient's tongue, preventing the tongue exposed from the shielding plate from swinging and contacting the mobile phone and causing injury.

As a further improvement of the above technical solution, there are multiple protrusions, and the multiple protrusions are distributed at intervals along the edge of the shielding plate.

A plurality of protrusions are distributed at intervals along the edge of the shielding plate, and at least one protrusion can extend into the space where liquid accumulates in the patient's mouth, thereby ensuring that the saliva suction function operates normally.

As a further improvement of the above technical solution, a plurality of the protrusions are arranged at the front end of the shielding plate, and at least one of the protrusions is arranged at the left end or the right end of the shielding plate.

When the doctor holds the handle and inserts the shield into the patient's mouth, the top wall or the bottom wall of the shield is pressed against the patient's tongue, the front end of the shield will extend to the root of the tongue, and the left end or the right end of the shield will extend into the space between the tongue and the teeth. Therefore, a protrusion is arranged at the left end or the right end of the shield to help the saliva suction holes on the protrusion absorb the liquid accumulated in the space.

As a further improvement of the above technical solution, the vertical cross-sectional area of the inner cavity gradually increases from front to back.

The channel of the handle is connected to the rear end of the inner cavity, and the channel absorbs air in the inner cavity from the rear end to form a negative pressure in the inner cavity. The vertical cross-sectional area of the inner cavity gradually increases from front to back, so that the inner cavity is a conical space that is larger at the front and smaller at the back. Since the liquid flows from the front end of the inner cavity with a smaller space to the rear end with a larger space, and a plurality of saliva suction holes are provided at the front end of the inner cavity, it is helpful to increase the suction formed by the saliva suction holes and improve the ability to absorb liquid.

As a further improvement of the above technical solution, the vertical width of the shielding plate gradually decreases from the back to the front.

The vertical width of the shielding plate gradually decreases from back to front, and the width of the horizontal section of the shielding plate gradually decreases from front to back, so the shielding plate is shovel-shaped with a larger front and a smaller back. When the doctor needs to perform surgery on the lower teeth, the shovel-shaped shielding plate can easily reach into the space between the tongue and the bottom of the tongue to lift the tongue.

As a further improvement of the above technical solution, the handle is a shapeable tube.

The handle can be shaped according to the doctor's needs to adapt to different usage scenarios. For example, the handle can be bent to the left or right, and after the doctor holds the handle to press the baffle against the patient's tongue, the handle deflects to the left or right side of the patient's mouth to avoid the handle obstructing the movement of the mobile phone inserted into the patient's mouth; or the handle can be bent to the upper or lower side, and after the doctor holds the handle to press the baffle against the patient's tongue, the handle deflects to the upper or lower side of the patient's mouth to avoid the handle obstructing the movement of the mobile phone inserted into the patient's mouth.

As a further improvement of the above technical solution, the handle includes a soft silicone tube and a metal wire built into the side wall of the soft silicone tube.

The handle is made of soft silicone tube and metal wire, making the outer texture of the handle softer to avoid crushing the patient's soft tissue.

As a further improvement of the above technical solution, the handle and the shielding plate are an integrally formed part, and the metal wire extends into the shielding plate.

The metal wire extends into the shielding plate. When the connection between the shielding plate and the handle is bent, the metal wire inside the shielding plate helps to maintain the shape of the rear end of the shielding plate, thereby preventing the rear end of the shielding plate from deforming and blocking the inner cavity and the channel.

As a further improvement of the above technical solution, the corners of the shielding plate are rounded.

Avoid scratching the patient's soft tissue with the sharp edges of the shield.

1 to 3 , the tongue shield of the present invention is provided in the following embodiments:

The tongue shield comprises a handle 100 , a shielding plate 200 , and a protrusion 300 , wherein the handle 100 is a shapeable tube.

The handle 100 is composed of a soft silicone tube 101 and a metal wire 102 built inside the soft silicone tube 101 .

The soft silicone tube 101, the baffle plate 200 and the protrusion 300 of the handle 100 are integrally formed. In the present embodiment, the soft silicone tube 101, the baffle plate 200 and the protrusion 300 of the handle 100 are made of silicone. During the manufacturing process, the tongue shield is firstly untied into two halves in the horizontal direction, and then the upper half and the lower half are separately molded. After the upper half and the lower half are molded, the two are closed and bonded together to combine the upper half and the lower half into the tongue shield.

The soft silicone tube 101 of the handle 100 is cylindrical and extends forward and backward. A channel 110 is provided inside the soft silicone tube 101 and passes through the tube in the forward and backward direction. The side wall of the soft silicone tube 101 is provided with two mounting holes that pass through the tube in the forward and backward direction. The two mounting holes are symmetrically distributed with the axis of the channel 110 as the center line.

The horizontal width of the shielding plate 200 gradually decreases from front to back, and the vertical width of the shielding plate 200 gradually increases from front to back. The outer shape of the shielding plate 200 is a shovel shape with a large front end and a small rear end. An inner cavity 210 is provided inside the shielding plate 200, and the rear end of the inner cavity 210 is connected to the front end of the channel 110. The horizontal width of the inner cavity 210 gradually decreases from front to back, and the vertical width of the inner cavity 210 gradually increases from front to back. The vertical cross-sectional area of the inner cavity 210 gradually increases from front to back.

The corners of the front end, left end, and right end of the shielding plate 200 are all rounded.

Two protrusions 300 are disposed at the front end of the shielding plate 200 , and a protrusion 300 is disposed at the left end of the shielding plate 200 , and the protrusion 300 protrudes toward the outside of the shielding plate 200 .

Each of the protrusions 300 is cylindrical, and a conducting hole extending along its own axis is provided inside the protrusion 300, and the conducting hole is connected to the inner cavity 210. A plurality of saliva suction holes 310 are provided on the outer wall of each protrusion 300, and the plurality of saliva suction holes 310 are distributed at intervals along the circumference of the protrusion 300, and a plurality of saliva suction holes 310 distributed at intervals are also provided on the end surface of the protrusion 300.

The rear side wall of the shielding plate 200 is provided with two assembly holes extending forward. The two assembly holes are symmetrically arranged on the left and right side walls of the shielding plate 200. The assembly holes extend forward along the side wall of the shielding plate 200, and the rear ends of the two assembly holes are connected to the front ends of the two mounting holes in a one-to-one correspondence.

The two metal wires 102 are respectively inserted into the two mounting holes, and extend from the mounting holes into the assembly holes, so that the metal wires 102 are located inside the side wall of the soft silicone tube 101 and inside the rear end of the baffle plate 200, so as to facilitate shaping of the soft silicone tube 101 and the baffle plate 200.

When using the tongue shield, the rear end of the channel 110 of the soft silicone tube 101 is connected to a negative pressure device, such as a vacuum tank, a negative pressure generator, a vacuum pump, etc. The negative pressure device forms a negative pressure in the channel 110, the inner cavity 210, and the plurality of saliva suction holes 310, so that the saliva suction holes 310 can absorb liquid; then the doctor shapes the handle 100, and changes the shape of the handle 100 by bending the soft silicone tube 101 and the metal wire 102, so that the relative position between the handle 100 and the shielding plate 200 is changed, for example, the handle 100 is bent to the left, right, upward or downward; then, the doctor holds the handle 100 and extends the shielding plate 200 into the patient's tongue. The top wall and the bottom wall of the shielding plate 200 are pressed against the patient's tongue to prevent the patient's tongue from swinging and affecting the doctor's operation of the mobile phone, and to prevent the swinging tongue from being accidentally injured by the mobile phone. The multiple protrusions 300 at the front end of the shielding plate 200 and the protrusion 300 at the left end can squeeze the soft tissue of the patient's oral cavity. Since the soft tissue of the patient's oral cavity is limited in deformation, the soft tissue cannot be completely wrapped around the outside of the protrusion 300, so that a gap is formed between the protrusion 300, the outer wall of the shielding plate 200, and the soft tissue, so that the saliva suction hole 310 on the upper part of the side wall of the protrusion 300 can absorb saliva, blood, cleaning fluid and other liquids from the gap to optimize the surgical field of view.

In some embodiments, the shielding plate 200 has various shapes. For example, the shielding plate 200 is in the shape of a flat plate, and the structure of the shielding plate 200 is simpler and easier to manufacture; or the shielding plate 200 is in the shape of an arch with the left and right ends bent downward and the middle arched upward, and the lower side of the shielding plate 200 forms a concave cavity for accommodating the patient's tongue, and the shape of the concave cavity matches the shape of the tongue to protect the tongue.

In some embodiments, the handle 100 is a tubular structure made of soft plastic, so that the handle 100 has a certain bending and deformation ability, and the doctor can bend the handle 100 within a certain limit. Alternatively, the handle 100 is made of a relatively soft metal material, such as a thin stainless steel tube, so that the handle 100 can be bent and shaped, and is not easy to break.

The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
