DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] See also Figure 1-Figure 5 The utility model provides the following technical solutions: an open mouth tongue depressor supporter, the open mouth tongue depressor supporter may include:

[0047] A support block 2, a telescopic component 1 and an operating mechanism 3, wherein the support block 2 has a slot 22, and the tongue depressor is located in the slot 22; the telescopic component 1 drives the support block 2 to adjust the support block 2; the operating mechanism 3 is installed on the telescopic component 1 to control the telescopic length of the telescopic component 1.

[0048] Furthermore, the tongue depressor is supported by the slot 22 provided in the support block 2, and the height of the support block 2 can be adjusted by adjusting the telescopic length of the telescopic assembly 1 through the operating mechanism 3, thereby adjusting the height of the tongue depressor in real time to meet the needs of the operation, which is conducive to the smooth and safe conduct of the operation.

[0049] Optionally, by Figure 1-Figure 3 , Figure 5As shown, in the present embodiment, at least two protrusions 21 are fixed on the support block 2, and the slot 22 is located between the at least two protrusions 21. Furthermore, the slot 22 can be formed by fixing two or more protrusions 21, or can be formed by opening on the support block 2. The slot 22 can also be deepened by fixing two protrusions 21. Preferably, the slot 22 is formed or deepened by fixing two protrusions 21. When the slot 22 is formed in the form of a protrusion 21, welding is preferably used. If there are other requirements, other detachable fixing forms can also be used, such as fixing the protrusion 21 with bolts. The length of the combination of the support block 2 and the protrusion 21 is about 2.5 cm and the width is about 2 cm.

[0050] Preferably, by Figure 1-Figure 3 , Figure 5 As shown, one end of the support block 2 is an arc end, and the slot 22 is located on the arc end of the support block 2. In the utility model, the top end of the support block 2 is an arc end, and its cross section is a semicircular structure. The slot 22 is opened on the arc end, or two or more protrusions 21 are fixed to form a slot 22 with an arc. This design can better cooperate with the tongue depressor, because the tail end of most tongue depressors is usually a handle, and is bent into a "V" shape with the body. The slot 22 of this design can be more stably inserted by the tongue depressor, because when the tongue depressor is inserted into the slot 22, the support block 2 will have two supporting positions that contact the tongue depressor to support the tongue depressor, which is further In order to ensure the stability of the tongue depressor, the width of the slot 22 is designed according to the width of the tongue depressor, preferably equal to the width of the tongue depressor, and by designing the slot 22 with a circular arc, it is also convenient to adjust the angle of the tongue depressor. For example, when the angle of the tongue depressor is adjusted by changing the height of the support block 2 (because the head end of the tongue depressor is inserted into the patient's mouth and presses down the patient's tongue, this end is approximately a fixed end, when the height of the other end of the tongue depressor is changed, the angle of the tongue depressor will change, and the height of the tongue depressor has been adjusted to the optimal height before being inserted into the patient's mouth), no matter what angle the tongue depressor is rotated to, the support block 2 will always have two supporting positions in contact with the tongue depressor.

[0051] It should be noted that although the arc-shaped design of the slot 22 is suitable for the tail end structure of most tongue depressors, when the tongue depressor is designed with other types, the structural form of the slot 22 can be changed and is not limited to the arc-shaped design. For example, for the "V"-shaped structure at the tail end of the tongue depressor, the slot 22 can also be designed as a V" shape, trapezoidal shape, etc. Preferably, an arc-shaped design is selected. As mentioned above, the slot 22 with an arc can not only ensure the stability of the tongue depressor when it is inserted, but also ensure the stability of the tongue depressor when adjusting the height and angle.

[0052] Further, by Figure 1 and Figure 2As shown, in this embodiment, the telescopic assembly 1 includes a sleeve 11 and a moving rod 12; one end of the moving rod 12 is located in the sleeve 11 to move the support block 2, and the overall height of the moving rod 12 when fully retracted is approximately 6.5 cm, and the maximum length of the moving rod 12 when extended is approximately 4 cm.

[0053] It should be noted that the present embodiment adopts a telescopic structure composed of a sleeve 11 and a movable rod 12 to change the position of the support block 2. For example, the height and angle of the tongue depressor can be adjusted by changing the height of the support block 2. However, the adjustment is not limited to using this telescopic structure. Other structures with the same functions can also be used to achieve the adjustment of the position of the support block 2, all of which fall within the protection scope of the present utility model.

[0054] It is also necessary to further explain that Figure 2 It can be seen from the telescopic structure shown that when the moving rod 12 is telescoped relative to the sleeve 11, the moving rod 12 will move along the extension line of the axial center line of the sleeve 11. The linear telescopic movement of the moving rod 12 relative to the sleeve 11 is only an exemplary representation of this embodiment. Under the premise that the position adjustment of the support block 2 can be satisfied, the moving rod 12 can also adopt other paths to telescope relative to the sleeve 11. For example, when the sleeve 11 and the moving rod 12 are both arc-shaped components, the telescopic path of the moving rod 12 is also arc-shaped.

[0055] Optionally, by Figure 3 As shown, in this embodiment, an operating mechanism 3 is also included, and the operating mechanism 3 includes a retaining frame 31, a turntable 32, and a spiral meshing portion 321. The retaining frame 31 is installed on the sleeve 11; the turntable 32 is rotatably installed on the retaining frame 31, a hole is opened on the sleeve 11, and the position of the turntable 32 is adapted to the position of the hole; the spiral meshing portion 321 is fixed on the turntable 32, and a plurality of meshing teeth 121 are fixed on the moving rod 12 and meshed with the spiral meshing portion 321. Further, the turntable 32 meshes with the meshing teeth 121 at the position of the hole. Therefore, when the turntable 32 is rotated, the turntable 32 will drive the spiral meshing portion 321 to rotate. Under the meshing action, the moving rod 12 is driven to move through the meshing teeth 121. The bidirectional rotation of the turntable 32 can realize the extension and retraction of the moving rod 12.

[0056] It is worth noting that Figure 3 and Figure 4 As shown, the spiral meshing portion 321 described in this embodiment is a spiral protrusion, and meshes with the meshing teeth 121. It can be easily determined that when a spiral groove is used, it can also mesh with the meshing teeth 121.

[0057] Preferably, by Figure 3As shown, in the present embodiment, the retaining frame 31 is rotatably arranged on the sleeve 11, wherein the spiral meshing portion 321 meshes with the meshing teeth 121 when the retaining frame 31 rotates counterclockwise, and the spiral meshing portion 321 is separated from the meshing teeth 121 when the retaining frame 31 rotates clockwise. Therefore, after adopting the above-mentioned design, when the position of the support block 2 needs to be adjusted during the operation, it can be achieved by rotating the turntable 32 in both directions. When the support device needs to be stored after the operation, the retaining frame 31 is rotated clockwise. At this time, the spiral meshing portion 321 is separated from the meshing teeth 121, and the moving rod 12 is released from the restriction. The moving rod 12 can automatically retract into the sleeve 11 under the action of its own gravity.

[0058] Optionally, by Figure 3 As shown, in this embodiment, a connecting member A is further included, and the retaining frame 31 is rotatably mounted on the sleeve 11 using the connecting member A.

[0059] Among them, the connecting member A may include a first bolt 5 and a first nut 6, a mounting ear 111 with a hole is fixed on the sleeve 11, and a second through hole 312 is opened on the retaining frame 31. The first bolt 5 passes through the mounting ear 111 with a hole and the second through hole 312, and is used to make the retaining frame 31 rotate with the axis of the first bolt 5 as the rotation axis. The first nut 6 is installed on the protruding end of the first bolt 5 by threaded engagement. In this embodiment, the first bolt 5 is used as the rotation axis for bidirectional rotation of the retaining frame 31, and the first nut 6 is installed on the protruding end of the first bolt 5 to limit the position and reduce the gap. The installation is carried out through the first bolt 5 and the first nut 6, which has the advantage of convenient disassembly and assembly, and the tightness can also be adjusted by rotating the first nut 6.

[0060] It should be noted that the retaining frame 31 is not limited to being installed using the first bolt 5 and the first nut 6. Under the premise that the retaining frame 31 can rotate in both directions, other components such as hinges, rotating rods, rivets, bearings, etc. can also be used for installation.

[0061] Preferably, by Figure 3 As shown, in this embodiment, a limiting mechanism 4 is also included. The limiting mechanism 4 is arranged on the retaining frame 31 and is used to control the rotation of the retaining frame 31. The limiting mechanism 4 includes an eccentric wheel 41 and a connecting member B. The eccentric wheel 41 is rotatably mounted on the sleeve 11 using the connecting member B.

[0062] The connecting member B may include a second bolt 7 and a second nut 8. A mounting hole 411 is provided at the eccentric position of the eccentric wheel 41. The eccentric position of the eccentric wheel 41 is a position deviated from the physical center of the eccentric wheel 41. A first through hole 311 is provided on the retaining frame 31, and the mounting hole 411 is adapted to the size of the first through hole 311. The second bolt 7 passes through the first through hole 311 and the mounting hole 411 to rotate the eccentric wheel 41. The second nut 8 is installed on the protruding end of the second bolt 7 by threaded engagement to reduce the gap. The rotation of the retaining frame 31 can be controlled by rotating the eccentric wheel 41 in both directions. For example, when the eccentric wheel 41 is rotated counterclockwise, the spacing between the mounting hole 411 and the moving rod 12 gradually increases, which will pull the retaining frame 31 to rotate counterclockwise and make the spiral meshing portion 321 mesh with the meshing teeth 121. Under the limiting action of the eccentric wheel 41, the retaining frame 31 will always remain in this position, which is convenient for more stable adjustment of the telescopic amount of the moving rod 12.

[0063] On the contrary, when the eccentric wheel 41 rotates clockwise, the distance between the mounting hole 411 and the moving rod 12 gradually becomes smaller, and the retaining frame 31 can be rotated clockwise by gently pushing the eccentric wheel 41. At this time, the spiral meshing portion 321 is separated from the meshing teeth 121, and the moving rod 12 is released from the restriction.

[0064] It should be noted that the eccentric wheel 41 is not limited to being installed using the second bolt 7 and the second nut 8. Under the premise that the eccentric wheel 41 can rotate in both directions, other components can also be used for installation, such as hinges, rotating rods, rivets, bearings, etc., which are installed using the second bolt 7 and the second nut 8. The installation has the advantage of convenient disassembly and assembly, and the tightness can also be adjusted by rotating the second nut 8.

[0065] Preferably, by Figure 3 As shown, in this embodiment, a lever 412 is fixed on the eccentric wheel 41. The lever 412 is preferably fixed to the eccentric wheel 41 by threaded engagement. Under the premise that the lever 412 can be stably fixed, other fixing methods may also be used, such as welding. By providing the lever 412, it is convenient to apply force to rotate the eccentric wheel 41.

[0066] It should be noted that when the lever 412 rotates to the bottom, the retaining frame 31 is pulled to rotate counterclockwise to the maximum position, and the spiral meshing portion 321 is meshed with the meshing tooth 121. At this time, the lever 412 will not rotate without external force, that is, the retaining frame 31 can be stably maintained in this state. When the retaining frame 31 needs to be rotated clockwise, the lever 412 needs to be pushed upward. At this time, the distance between the mounting hole 411 and the moving rod 12 gradually becomes smaller. When the lever 412 rotates to the top, the lever 412 is gently pushed to use the eccentric wheel 41 to push the retaining frame 31 to rotate clockwise. Because this state is not a working state, the retaining frame 31 does not need to remain stable in this state.

[0067] Optionally, by Figure 3 and Figure 4 As shown, in this embodiment, a connecting member C is further included, and the turntable 32 is rotatably mounted on the retaining frame 31 using the connecting member C.

[0068] The connecting member C may include a fixing rod 313 with an internal thread, a sleeve 322, a third bolt 9 and a connecting plate 323. The fixing rod 313 is fixed on the retaining frame 31. The turntable 32 has a center hole. The sleeve 322 is sleeved on the fixing rod 313. The sleeve 322 is located in the center hole to make the turntable 32 rotate. The length of the sleeve 322 is about 1 cm. The third bolt 9 penetrates the sleeve 322 and is screwed into the fixing rod 313 by threaded engagement. The sleeve 322 sleeves the fixing rod 313 to form a rotating structure, so as to realize the rotating installation of the turntable 32. The third bolt 9 is installed to limit the position, so as to ensure the stability of the turntable 32.

[0069] It should be noted that the turntable 32 is not limited to adopting this rotating structure. Under the premise that the turntable 32 can rotate in both directions, other installation methods can also be adopted, such as directly fixing it through a bearing, that is, the inner ring of the bearing is fixed to the fixing rod 313, and the turntable 32 is fixed to the outer ring of the bearing. Compared with the rotating structure of this embodiment, the turntable 32 can be easily disassembled after unscrewing the third bolt 9, which makes maintenance more convenient, and the tightness can be adjusted by rotating the third bolt 9.

[0070] Optionally, by Figure 3 and Figure 4 As shown, in this embodiment, a connecting plate 323 is fixed to the end of the sleeve 322, and a rotatable hand crank 324 is installed on the connecting plate 323. The turntable 32 is rotated by the hand crank 324 and the connecting plate 323, which is more convenient and labor-saving.

[0071] The length of the connecting plate 323 is 2 cm, the width is 0.4 cm, and the length of the hand crank 324 is about 1 cm. In the utility model, the turntable 32, the spiral meshing portion 321, the sleeve 322 and the connecting plate 323 are preferably cast as an integral component with high structural strength. Because the support is used to support the tongue depressor, the requirements are not high, and the support will not be deformed due to excessive weight. The turntable 32, the spiral meshing portion 321, the sleeve 322 and the connecting plate 323 can also be fixed in a conventional manner by combining several accessories.

[0072] It should be further explained that the installation method of the hand crank 324 is the same as that of the turntable 32, and both can be rotated in both directions, which will not be described in detail here.

[0073] Preferably, by Figure 2As shown, in this embodiment, the telescopic assembly 1 also includes a base 14 and a diagonal support rod 13. The sleeve 11 is fixed on the base 14. The diagonal support rod 13 is fixed between the sleeve 11 and the base 14 in an inclined state. The size of the base 14 is 8 cm in length, 5 cm in width, and 0.5 cm in height. It is used for stable support to ensure the stability of the upper sleeve 11 and the moving rod 12. The diagonal support rod 13 further improves the stability of the sleeve 11. The sleeve 11 and the diagonal support rod 13 can be installed in a conventional manner, such as fixing with bolts.

[0074] It should be further explained that the support device of the present invention also has the advantage of being easy to disinfect, mainly because the various accessories of the support device can be fully exposed, and as can be seen from the above introduction, the movable rod 12 can be easily detached from the sleeve 11 and used after being fully disinfected, which is safer and avoids cross-infection accidents.

[0075] Working principle and use process of the utility model: When the tongue depressor and support device of the utility model are used, the patient is first placed at a suitable position after anesthesia. The bottom support frame is a pre-installed component. A suitable bottom support frame can be designed according to actual conditions, or suitable tools can be used at the surgical site, such as a sterile bowl or a sterile treatment towel pad, which is disinfected before use;

[0076] After the bottom support frame is placed, the sterile treatment towel is covered on the bottom support frame, and then the mouth opener is used to open the patient's mouth, and the sterile supporter that has been disinfected is placed on the bottom support frame, and the tongue depressor tail end of the mouth opener is inserted into the card slot 22 to fix it, and the height can be adjusted according to the situation by shaking the hand rocker 324;

[0077] The support device of the utility model has a very stable supporting effect on the tongue depressor of the mouth opener, and can adjust the required height and angle of the tongue depressor in real time according to the needs of the operation, which is conducive to the smooth and safe operation.

[0078] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
