Description

Technical Field

[0001] This invention relates to the field of oral medical auxiliary device technology, specifically to a saliva suction tube support and adjustment device installed on a dental chair instrument rack, and more particularly to an oral saliva suction tube support and adjustment device having an insertable mounting base, a switch linkage structure, an adjustable damping universal connection structure, and a replaceable clamping structure. Background Technology

[0002] In clinical dental treatment, strong and weak suction tubes are commonly used auxiliary instruments, typically used to remove saliva, cooling fluid, debris, and liquids or mists generated during treatment. Most existing suction tubes rely on the instrument racks attached to the dental chair for placement and retrieval; their primary function is storage, lacking stable external support, adjustable positioning, and the ability to remain suspended for extended periods. In actual clinical application, doctors or assistants often need to repeatedly adjust the angle and position of the suction tube based on the patient's position, the intraoral operating area, the treatment direction, and the treatment steps. If relying solely on handheld devices, it easily increases the workload of assistants and makes it difficult to maintain stability during prolonged treatments. If conventional external clamping supports are used, they often have the following shortcomings: First, existing external supports are typically installed by clamping to the edge of the dental chair, attaching to the edge of the tray, or by hanging externally, resulting in poor compatibility with different dental chair models, limited installation positions, insufficient stability, and potential disruption to the existing instrument layout and clinical operating space. Second, some dental chairs already have built-in switch mechanisms for controlling the opening and closing of the suction station, but existing additional supports often cannot simultaneously accommodate both support installation and the original switch mechanism. The existing auxiliary switches are characterized by several issues: First, they can cause loss of original function or inconvenience in use. Second, while conventional ball-head connections or simple flexible connectors can achieve a certain angle adjustment, they lack structures that combine damping retention, limiting and preventing dislodgement, and repeatable positioning capabilities, often resulting in loosening, sagging, or rebound during clinical use. Third, most existing clamping ends can only accommodate a single size of suction tube, making it difficult to accommodate instruments with significant diameter differences, such as strong and weak suction tubes, hindering rapid switching. Fourth, existing auxiliary switches are mostly temporary plugs or simple pressing structures, lacking a low-cost auxiliary switch solution that can be stably installed, quickly switched, and sustainably maintained. Therefore, there is an urgent need for an oral suction tube support and adjustment device that can be directly installed using the existing instrument rack in the dental chair, and can achieve multi-model base adaptation, switch linkage, damping universal adjustment, quick-release tube clamp replacement, and optional simple switch auxiliary control, to meet the application needs of different dental chairs, different suction tubes, and different clinical operation scenarios. Summary of the Invention

[0003] The purpose of this invention is to provide an oral suction tube support and adjustment device to solve the problems of existing suction tube supports, such as single installation method, poor compatibility, limited adjustment angle, insufficient stability, difficulty in adapting to different specifications of suction tubes, and difficulty in taking into account the original switching positions of the dental chair.

[0004] Technical Solution: To achieve the above objectives, the present invention provides an oral suction tube support and adjustment device, including a mounting base assembly, a support and adjustment assembly, and a clamping assembly.

The other end of the ball connecting rod 11 is connected to the rotating screw rod 12; the screw knob 13 is threadedly connected to the rotating screw rod 12; the tube clamp 14 is detachably connected to the rotating screw rod 12 and clamps and fixes the saliva suction tube 18 under the action of the screw knob 13; the locking pin 15 is used to further lock the tube clamp 14 to the rotating screw rod 12.

[0006] In a preferred embodiment, the universal base 1 includes a switchless universal base 1A, a switch-equipped strong suction universal base 1B, and a switch-equipped weak suction universal base 1C.

It should be understood that the universal base 1 is not limited to the above three specific forms; it can also be configured in other adaptable forms according to the size, depth, switch position, switch state, and suction tube specifications of the instrument hanger 17. The base retaining sleeve 2 can also be configured in various different specifications to adapt to universal bases 1 of different shapes or sizes. Each base retaining sleeve is provided with a sleeve connection inlet and an internal connection thread. Some base retaining sleeves are provided with sleeve wing plates on the outside to enhance the convenience of screwing and securing. In another preferred embodiment, the mounting base assembly further includes a switch linkage structure. This switch linkage structure includes a spherical wing rotating slider 3 disposed within the switch receiving hole and a ball-end operating rod 4 linked thereto. The spherical wing rotating slider 3 includes a strong-suction type spherical wing rotating slider 3A and a weak-suction type spherical wing rotating slider 3B, each with an internal connecting thread 3A1 / 3B1, a slider spherical wing 3A2 / 3B2, and a slider rotation groove 3A3 / 3B3. The ball-end operating rod 4 includes a strong-suction type ball-end operating rod 4A and a weak-suction type ball-end operating rod 4B, each with an operating rod connecting thread 4A1 / 4B1 and an operating rod ball end 4A2 / 4B2. The ball-end operating rod 4 is connected to the spherical wing rotating slider 3 via the operating rod connecting thread. The rotating shaft 1B6 / 1C6 on the universal base 1 is embedded in the corresponding slider rotation groove 3A3 / 3B3, allowing the spherical wing rotating slider 3 to rotate within the switch receiving hole, and achieving switch toggle and limit control through the limit trajectory groove. It should be understood that the preferred connection between the spherical wing rotating slider 3 and the ball-end operating rod 4 is a threaded connection, but a snap-fit ​​connection or other equivalent connection methods that can achieve linkage control can also be used. The moving parts and external operating parts in the switch linkage structure are not limited to the specific forms described above. As long as they can achieve the pushing, releasing, or limiting control of the original workstation switch, they can all be used as equivalent implementations of the present invention. In another preferred embodiment, the universal shaping support rod 5 includes a first end connecting thread 501, a universal shaping support rod body 502, and a second end connecting thread 503, used to connect the universal base 1 and the connecting column 6, and to maintain a predetermined shape after external force adjustment. It should be understood that the universal shaping support rod 5 can be implemented using a metal shaping rod, a gooseneck support, a malleable composite support, or other support components capable of maintaining their shape after adjustment. In another preferred embodiment, the connecting post 6 is provided with a connecting post connection inlet 601, a connecting post internal connection thread 602, a connecting post wing 603, a connecting post external connection thread 604, and a connecting post ball limiting protrusion 605; the locking cover 7 is provided with a locking cover internal connection thread 701, a locking cover upper edge limiting ring 702, and a locking cover wing 703; the open-type limiting ball cap 8 is provided with a ball cap locking pin hole 801, a ball cap U-shaped opening 802, and a ball cap lower edge limiting ring 803; the limiting ring 9 is provided with a limiting ring locking pin hole 901 and a limiting ring U-shaped opening 902; the ball connecting rod 11 is provided with a connecting rod internal connection thread 1101 and a connecting rod ball head 1102. By tightening the locking cover 7 relative to the connecting post 6, the holding force of the connecting post ball limiting protrusion 605 and the open-type limiting ball cap 8 on the connecting rod ball head 1102 can be changed, thereby adjusting the rotational damping of the ball connecting rod 11. It should be understood that the adjustable damping universal joint structure is not limited to the specific component forms mentioned above. As long as it can achieve multi-directional adjustment of the ball joint relative to the limiting member, restriction of the expansion of the limiting member by the external constraint member, and adjustment of the damping by the locking adjustment member, it can be regarded as an equivalent implementation of the present invention. In another preferred embodiment, the rotating screw rod 12 is provided with a screw rod locking pin hole 1201, a screw rod connecting post 1202, and a screw rod threaded rod 1203; the screw knob 13 is provided with a knob internal connecting thread 1301 and a knob wing 1302. The pipe clamp 14 includes a strong suction type pipe clamp 14A and a weak suction type pipe clamp 14B, and is provided with a saliva suction pipe holding hole 14A1 / 14B1, a pipe clamp inner groove 14A2 / 14B2, a pipe clamp rotating connecting post slot 14A3 / 14B3, a pipe clamp locking pin hole 14A4 / 14B4, a pipe clamp limiting groove 14A5 / 14B5, and a pipe clamp limiting groove 14A6 / 14B6. A detachable connection structure of insertion-rotation-limiting is formed between the rotating screw rod 12 and the pipe clamp 14. The locking pin 15 can be selectively inserted into the locking pin hole 1201 of the screw rod and the locking pin hole 14A4 / 14B4 of the pipe clamp to achieve anti-disengagement locking between the pipe clamp 14 and the rotating screw rod 12. It should be understood that the detachable connection relationship in the clamping assembly is preferably an insertion-rotation-limiting method, but it can also be achieved by using an equivalent snap-fit ​​limiting, plug-in limiting, or plug-in plus locking structure. The pipe clamp 14 is not limited to two specific specifications: strong suction type and weak suction type. As long as it can adapt to saliva tubes 18 with different outer diameters or shapes, it can be achieved by changing the dimensional relationship of the clamping hole, the limiting groove, and the connecting groove. In another preferred embodiment, a simple switch 16 may also be provided. The simple switch 16 can be independently mounted on the instrument hanger 17 for auxiliary control of the existing saliva tube station switch. The simple switch 16 includes a strong suction type simple switch 16A and a weak suction type simple switch 16B, both of which are equipped with switch retaining wing protrusions 16A1 / 16B1. It should be understood that the simple switch 16, as a supplementary embodiment, can form an instantaneous or continuous control state through its engaging interaction with the instrument hanger 17 without changing the installation state of the main support device.

[0007] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The insertion-type installation and fixation structure composed of the universal base 1 and the base fixing sleeve 2 allows for direct installation using the existing instrument rack 17 positions of the dental chair, avoiding additional modifications, making installation convenient, disassembly and assembly easy, and with a wide range of applicability. 2. The universal base 1 can be configured as a switchless type, a switch-equipped strong suction type, and a switch-equipped weak suction type, depending on whether the position has a switch and the specifications of the suction tube, thus accommodating different dental chair position structures and different usage scenarios. 3. Through the cooperation of the spherical wing rotating slider 3 and the ball end operating rod 4, the original position switch of the dental chair can be linked for operation, retaining the original position function while expanding the support function. 4. The adjustable damping universal connection structure formed by the connecting column 6, locking cover 7, open-type limiting ball cap 8, limiting ring 9, locking pin 10, and ball connecting rod 11 can achieve stable suspension after multi-directional adjustment, and has the functions of smooth adjustment, damping locking, and anti-dislodgement limiting. 5. The tube clamp 14 has a replaceable structure, allowing for replacement according to the diameter and shape of strong and weak suction tubes, improving clinical versatility. 6. The rotating screw rod 12 and the tube clamp 14 use an insertion-rotation-limiting connection structure, further secured by a locking pin 15 to prevent detachment, facilitating replacement and ensuring operational stability. 7. The simple switch 16 can be installed as an independent accessory on the instrument hanger 17, providing quick auxiliary control of the existing switch; it is simple in structure, easy to manufacture, and flexible in use.

[0009] Detailed Description of Embodiments: The present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the following detailed description is only for explaining the present invention and is not intended to limit the scope of protection of the present invention. Figure 1 , Figure 18 , Figure 19 and Figure 20 As shown, this invention provides an oral suction tube support and adjustment device, including a universal base 1, a base fixing sleeve 2, a spherical wing rotating slider 3, a ball-end operating rod 4, a universal shaping support rod 5, a connecting column 6, a locking cap 7, an open-type limiting ball cap 8, a limiting ring 9, a locking pin 10, a ball connecting rod 11, a rotating screw rod 12, a screw knob 13, a tube clamp 14, and a locking pin 15; depending on different usage scenarios, a simple switch 16 can also be provided. The instrument hanger 17 and the suction tube 18 are the objects used in conjunction with this invention.

[0010] Example 1: Main support structure like Figure 2 , Figure 3 and Figure 9As shown, the universal base 1 is used to insert into the existing work position of the instrument hanger 17 and is fixed in place by the base retaining sleeve 2. The universal base 1 can be configured in three forms: a switchless universal base 1A, a switch-enabled strong suction universal base 1B, and a switch-enabled weak suction universal base 1C, to adapt to different dental chair work positions and different types of suction tubes. The switchless universal base 1A has a base connection inlet 1A1, an inner base connection thread 1A2, and an outer base connection thread 1A3; the switch-enabled strong suction universal base 1B has a base connection inlet 1B1, an inner base connection thread 1B2, an outer base connection thread 1B3, a switch receiving hole 1B4, a limit track groove 1B5, and a rotating shaft 1B6; the switch-enabled weak suction universal base 1C has a base connection inlet 1C1, an inner base connection thread 1C2, an outer base connection thread 1C3, a switch receiving hole 1C4, a limit track groove 1C5, and a rotating shaft 1C6. The base retaining sleeve 2 can be configured as a first base retaining sleeve 2A, a second base retaining sleeve 2B, a third base retaining sleeve 2C, a fourth base retaining sleeve 2a, a fifth base retaining sleeve 2b, and a sixth base retaining sleeve 2c, depending on the base model. Each base retaining sleeve is equipped with a sleeve connection inlet and an internal connecting thread for engaging with the external connecting thread on the outside of the universal base 1. Some base retaining sleeves also have sleeve flaps for easy screwing and securing. During installation, the universal base 1 is first inserted into the existing position of the instrument hanger 17, and then the matching base retaining sleeve 2 is externally fitted onto the lower part of the universal base 1 and secured by screwing. This structure utilizes the existing position of the dental chair to complete the bracket installation, requiring no external clamps or additional modifications, making installation convenient and disassembly quick.

[0011] Example 2: Switch Control Structure like Figure 4 , Figure 10 and Figure 11As shown, when using a universal base 1B with a strong suction and a universal base 1C with a weak suction and a switch, a spherical wing rotating slider 3 can be installed in the switch receiving hole of the universal base, and cooperate with the ball-end operating rod 4 to form a switch linkage structure. The spherical wing rotating slider 3 includes a strong suction type spherical wing rotating slider 3A and a weak suction type spherical wing rotating slider 3B. The spherical wing rotating slider 3 is provided with a slider internal connecting thread 3A1 / 3B1, a slider spherical wing 3A2 / 3B2, and a slider rotation groove 3A3 / 3B3. The ball-end operating rod 4 includes a strong suction type ball-end operating rod 4A and a weak suction type ball-end operating rod 4B. The ball-end operating rod 4 is provided with an operating rod connecting thread 4A1 / 4B1 and an operating rod ball end 4A2 / 4B2. During assembly, the ball-end operating lever 4 is connected to the inner connecting thread of the spherical wing rotating slider 3 via the operating lever connecting thread. The rotating shaft 1B6 or 1C6 on the universal base 1 is embedded in the corresponding slider rotating groove 3A3 or 3B3, allowing the spherical wing rotating slider 3 to rotate within the switch receiving hole. In use, the operator moves the ball-end operating lever 4, and the spherical wing rotating slider 3 moves within the limit trajectory groove, thereby achieving the toggle control of the original workstation switch of the dental chair. It should be understood that the above-mentioned switch linkage structure can also adopt other equivalent connection methods or moving part forms, as long as it can achieve the linkage control of the original workstation switch, it can fall within the protection scope of this invention.

[0012] Example 3: Universal Shaping Support and Adjustable Damping Universal Connection Structure like Figure 5 , Figure 6 , Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, the universal support rod 5 includes a first end connecting thread 501, a universal support rod body 502, and a second end connecting thread 503. The first end connecting thread 501 is connected to the inner connecting thread of the universal base 1, and the second end connecting thread 503 is connected to the inner connecting thread 602 of the connecting post 6. The universal support rod body 502 is a flexible structure that can maintain its shape, allowing the bracket to maintain the required spatial position after adjustment. The connecting post 6 is provided with a connecting post inlet 601, an inner connecting thread 602, a connecting post wing 603, an outer connecting thread 604, and a connecting post ball limiting protrusion 605. The connecting post 6 is used to connect with the universal support rod 5 and also serves as the connecting body of the rear universal locking structure. The locking cover 7 is provided with an inner connecting thread 701, an upper edge limiting ring 702, and a locking cover wing 703. The open-type limiting ball cap 8 has a ball cap locking pin hole 801, a ball cap U-shaped opening 802, and a ball cap lower edge limiting ring 803. The limiting ring 9 has a limiting ring locking pin hole 901 and a limiting ring U-shaped opening 902. The locking pin 10 is used to pass through the corresponding pin hole. The ball connecting rod 11 has a connecting rod internal connecting thread 1101 and a connecting rod ball head 1102. During assembly, first press the ball head 1102 into the open-type limiting ball cap 8, then install the open-type limiting ball cap 8 into the locking cover 7, and then screw the locking cover 7 onto the connecting post external connecting thread 604 of the connecting post 6, so that the ball head 1102 is located between the connecting post ball limiting protrusion 605 and the open-type limiting ball cap 8. Subsequently, the limiting ring 9 is fitted onto the outside of the open-type limiting ball cap 8, and the locking pin 10 passes through the locking pin hole 901 of the limiting ring and the locking pin hole 801 of the ball cap, thereby restricting the outward expansion of the open-type limiting ball cap 8. By adjusting the tightness of the locking cover 7 relative to the connecting post 6, the pressing force of the ball limiting protrusion 605 of the connecting post and the open-type limiting ball cap 8 on the ball head 1102 can be changed, thereby adjusting the rotational damping of the ball connecting rod 11. This structure can realize multi-directional rotation of the ball connecting rod 11, and can also form a stable hovering state after adjustment, while having a good limiting and anti-detachment effect.

[0013] Example 4: Quick-connect and clamping structure for pipe clamps like Figure 7 , Figure 16 and Figure 17As shown, the rotating screw rod 12 has a screw rod locking pin hole 1201, a screw rod connecting post 1202, and a screw rod threaded rod 1203; the screw knob 13 has an internal connecting thread 1301 and a knob wing 1302. The internal connecting thread 1101 of the connecting rod at one end of the ball connecting rod 11 is used to connect with the rotating screw rod 12. During assembly, after the rotating screw rod 12 passes through the end of the ball connecting rod 11, it is screwed onto the outside of the threaded rod 1203 by the screw knob 13. The pipe clamp 14 includes a strong suction type pipe clamp 14A and a weak suction type pipe clamp 14B. The tube clamp 14 is provided with a suction tube holding hole 14A1 / 14B1, a tube clamp inner groove 14A2 / 14B2, a tube clamp rotating connecting post groove 14A3 / 14B3, a tube clamp locking pin hole 14A4 / 14B4, a tube clamp limiting groove 14A5 / 14B5, and a tube clamp limiting slot 14A6 / 14B6. The screw rod connecting post 1202 of the rotating screw rod 12 can be inserted into the corresponding part of the tube clamp 14 and enters a limiting state by rotation, forming a detachable connection method of insertion-rotation-limiting. The non-circular connecting section of the ball connecting rod 11 cooperates with the tube clamp rotating connecting post groove 14A3 / 14B3 to limit the up-and-down swing of the tube clamp 14 relative to the ball connecting rod 11. After the screw knob 13 is tightened, a clamping force can be applied to the tube clamp 14, so that the tube clamp 14 stably clamps the suction tube 18. When a certain specification of pipe clamp needs to be used for a long period of time, the locking pin 15 can be passed through the screw rod locking pin hole 1201 and the corresponding pipe clamp locking pin hole 14A4 / 14B4 to form an additional anti-disengagement lock. When it is necessary to replace the pipe clamp with a different specification, simply release the locking pin 15 and rotate it out in the predetermined direction to achieve quick replacement. It should be understood that the quick-release connection in the clamping assembly can also be implemented in other equivalent ways. As long as the installation, removal, limiting and stable clamping of the pipe clamp can be achieved, they can all fall within the protection scope of this invention.

[0014] Example 5: Simple Switch Structure like Figure 8 and Figure 21 As shown, the present invention can also be equipped with a simple switch 16 independently. The simple switch 16 includes a strong suction type simple switch 16A and a weak suction type simple switch 16B, which are respectively provided with switch retaining wing protrusions 16A1 and 16B1. The simple switch 16 is generally in the shape of an arc-shaped thin sheet, and its lower part can be inserted into the corresponding work position of the instrument hanger 17, and forms a locking relationship with the instrument hanger 17 through the switch retaining wing protrusion. In use, the simple switch 16 can be kept in its natural state, or it can be rotated at a small angle after being pressed down to lock it in a locked state to maintain continuous pressure on the original work position switch; when it needs to be released, it can be released by rotating in the opposite direction. This structure is simple, easy to manufacture, and low in cost, and can be used as an independent auxiliary accessory.

[0015] Example 6: Overall Usage Process like Figure 19 and Figure 20As shown, in use, first, according to the position of the dental chair instrument rack 17 and the type of suction tube 18, select the appropriate universal base 1 and base fixing sleeve 2, and install them in the corresponding position of the instrument rack 17. If a switch control function is required, then simultaneously assemble the spherical wing rotating slider 3 and the ball end operating lever 4. Then, connect the universal shaping support rod 5, connecting column 6, locking cover 7, open-type limiting ball cap 8, limiting ring 9, locking pin 10, and ball connecting rod 11 in sequence to form an adjustable damping universal structure. Next, select the strong suction type tube clamp 14A or weak suction type tube clamp 14B according to the type of suction tube, and assemble the rotating screw rod 12, screw knob 13, and locking pin 15. Finally, clamp the strong suction type saliva tube 18A or weak suction type saliva tube 18B in the corresponding tube clamp 14. Through the cooperation of the universal shaping support rod 5, the ball connecting rod 11, and the tube clamp 14, the flexible adjustment of the suction tube in spatial position and angle can be achieved. After adjustment, the saliva suction tube can be stably suspended in the target position, which is convenient for clinical operation; after use, the saliva suction tube should be adjusted and returned to the corresponding work position.
