Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a water-collecting pull hook with a saliva suction tube. Background Technology

[0002] Saliva suction tubes are commonly used medical instruments in dentistry, primarily used to aspirate saliva and rinsing solutions from the oral cavity to prevent interference with wound healing or oral procedures. Currently, commercially available saliva suction tubes have relatively limited functionality. During oral procedures, firstly, the patient's tongue is easily injured by dental instruments, and the shape of the saliva suction tube makes it difficult to restrict tongue movement while aspirating rinsing solutions. Secondly, the separate design of the saliva suction tube and cheek retractor requires the operator to operate both simultaneously to achieve adequate operating space, making the process cumbersome. Furthermore, during dental filling treatments, when using a three-way nozzle to rinse away etching agents from the tooth surface, the shape of the saliva suction tube prevents it from promptly aspirating the rinsing solution, causing the etching agent to flow in the mouth and irritate the patient's oral mucosa. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a water-collecting suction hook with a suction tube that can switch between a tongue-blocking state and a cheek-pulling hook state, while simultaneously allowing the suction tube to promptly remove rinsing fluid or saliva.

[0004] To achieve the above objectives, this utility model first proposes a water-gathering hook with a saliva suction tube, including a water-gathering device, a hook, and a tube clamp. The water-gathering device includes a base plate, side guards, and a bottom guard. The base plate is fan-shaped, and the arc edge of the side with the smaller diameter of the base plate is used to abut against the teeth to form an abutment side. Side guards are fixed on both sides of the base plate, and a bottom guard is fixed on the abutment side of the base plate. The side guards and the bottom guard surround one side of the base plate to form a water-gathering area. A tube clamp is fixed on the side of the base plate where the water-gathering area is located, and a hook is rotatably mounted on the other side. The hook is fixed by a limiting device to limit its angle after rotation.

[0005] In this embodiment, the hook is a U-shaped hook, which is connected to the base plate by bolts. A first anti-slip pad is provided on the contact side of the hook with the bolt and the base plate. The first anti-slip pad and the bolt cooperate to form a limiting device for the hook.

[0006] In this embodiment, the pipe clamp is a C-type buckle, and a second anti-slip pad is installed on the inner wall of the pipe clamp.

[0007] In this embodiment, the bottom stop is an arc-shaped stop, and the arc of the bottom stop matches the arc of the side with the smaller diameter of the bottom plate.

[0008] In this embodiment, the side guard and the bottom guard are sealed together, and the connection between the side guard and the bottom guard, the connection between the side guard and the bottom plate, and the connection between the bottom guard and the bottom plate are all smooth rounded corners. The edges of the side guard and the bottom guard themselves are also smooth rounded corners.

[0009] In this embodiment, the length of the bottom edge matches the width of the neck of one tooth or the neck width of two teeth.

[0010] With the above structure, this utility model has the following advantages:

[0011] 1. The hook in this application adopts a U-shaped design. By rotating the hook, it can be switched between the tongue blocking state and the cheek hook state. In the cheek hook state, the corner of the mouth can be pulled to widen the operator's field of vision. In the tongue blocking state, the tongue can be pulled to prevent the instrument from accidentally injuring the tongue during oral operation.

[0012] 2. The side and bottom baffles of the water-gathering device enclose a water-gathering area on one side of the base plate. The saliva suction tube is fixed to the water-gathering area by a tube clamp. When in use, place the water-gathering device against the teeth, and at the same time place the suction head of the saliva suction tube at the bottom baffle of the water-gathering device. Adjust the direction of the three-way gun's water flow toward the water-gathering device, and the rinsing liquid will be gathered at the bottom baffle. At the same time, the saliva suction tube can promptly and stably remove the rinsing liquid. The position of the saliva suction tube can be adjusted and fixed by the tube clamp, and the saliva suction tube can promptly remove the rinsing liquid or saliva in different operating tooth positions.

[0013] 3. The hook of this application is fixed by limiting its angle after rotation through a limiting device. The hook is connected to the base plate by bolts. A first anti-slip pad is provided on the contact side of the hook with the bolt and the base plate. The static friction generated by the first anti-slip pad and the bolt forms a limiting device for limiting the angle of the hook. When the hook rotates around the bolt, due to the presence of the first anti-slip pad, the hook can be positioned under the action of friction after rotation, so that the hook can be easily switched between the tongue blocking state and the cheek hook state.

[0014] 4. The clamp of this application is provided with a second anti-slip pad, which increases the friction between the saliva tube and the clamp, preventing the saliva tube from rotating and slipping inside the clamp, thereby fixing the saliva tube.

[0015] In summary, this invention can switch between a tongue-blocking state and a cheek-pulling hook state, while allowing the saliva suction tube to promptly remove rinsing fluid or saliva. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] like Figures 1 to 4 As shown, a water-collecting pull hook with a saliva suction tube includes a water-collecting device 1, a pull hook 2, and a tube clamp 3.

[0024] The water-collecting device 1 includes a base plate 13, side baffles 11, and bottom baffles 12. The base plate 13 is fan-shaped, and the arc edge of the smaller diameter side of the base plate 13 is used to abut against the teeth to form an abutment side. Side baffles 11 are fixed on both sides of the base plate 13, and bottom baffles 12 are fixed on the abutment side of the base plate 13. The bottom baffles 12 are arc-shaped, and their curvature matches that of the arc edge of the smaller diameter side of the base plate 13. The side baffles 11 and bottom baffles 12 enclose one side of the base plate 13 to form a water-collecting area. The side guard 11 and the bottom guard 12 are connected and sealed to each other. The connection between the side guard 11 and the bottom guard 12, the connection between the side guard 11 and the bottom plate 13, and the connection between the bottom guard 12 and the bottom plate 13 are all smooth rounded corners. The edges of the side guard 11 and the bottom guard 12 themselves are also smooth rounded corners to prevent damage to oral tissues during treatment. In this embodiment, the length of the bottom guard 12 matches the width of a tooth or the neck width of two teeth, and the curvature of the bottom guard 12 matches the curvature of the tooth neck.

[0025] The base plate 13 has a pipe clamp 3 fixed on one side where the water collection area is located, and a hook 2 is rotatably mounted on the other side. The central axis of the pipe clamp 3 is arranged radially along the fan-shaped base plate 13. The hook 2 is fixed by limiting the angle after rotation through a limiting device.

[0026] like Figure 3 , 4 As shown, the hook 2 is a U-shaped hook. The hook 2 is connected to the base plate 13 by bolt 4. A first anti-slip pad 6 is provided on the contact side of the hook 2, bolt 4 and base plate 13. The first anti-slip pad 6 and bolt 4 cooperate to form a limiting device for the hook 2. When in use, the bolt 4 is tightened to a preset value. At this time, the hook 2 can rotate around the bolt 4. Due to the presence of the first anti-slip pad 6, the hook 2 can be positioned under the action of friction after rotation, so that the hook 2 can switch between the tongue blocking state and the cheek hook state. In the tongue blocking state, the opening of the hook 2 faces away from the abutting side of the water collecting device 1. In the cheek hook state, the opening of the hook 2 faces the abutting side of the water collecting device 1.

[0027] like Figure 2 As shown, the clamp 3 is a C-type buckle. The inner diameter of the clamp 3 is slightly smaller than the outer diameter of the saliva suction tube 5. A second anti-slip pad 31 is installed on the inner wall of the clamp 3. The second anti-slip pad 31 increases the friction between the saliva suction tube 5 and the clamp 3, preventing the saliva suction tube from rotating and slipping inside the clamp, thereby fixing the saliva suction tube. The diameter of the suction head 51 of the saliva suction tube 5 is larger than the diameter of the clamp. When the saliva suction tube 5 is fixed inside the clamp 3, it can prevent the suction head 51 from coming out.

[0028] In this embodiment, the water collection device 1, hook 2, pipe clamp 3, and bolt 4 are all made of polymer resin material.

[0029] When using this device, during dental filling treatment, after the etching operation, when using the three-way gun to blow the etching agent away from the affected tooth, adjust the suction head 51 of the suction tube to the bottom edge 12, and at the same time, align the bottom edge 12 with the neck of the tooth. Direct the water spray from the three-way gun towards the water collection device 1. At this time, the water collection area cooperates with the tooth, which can block and gather the washed-away etching agent and water at the position of the suction head 51, so that the suction head 51 can promptly suck away the etching agent and water.

[0030] like Figure 3 As shown, the hook 2 can rotate 360° around the bolt, and after rotation, the static friction generated by the cooperation of the first anti-slip pad 6 and the bolt 4 can keep the hook 2 stably in the position after rotation. When the hook 2 is adjusted to the tongue stop state, so that the opening of the hook 2 faces away from the contact side of the water collection device 1, the hook 2 works as a tongue stop. The hook 2 is placed between the teeth and the tongue. During oral operation, the tongue is placed in the opening of the hook 2, thereby preventing accidental injury to the tongue during operation.

[0031] like Figure 4As shown, rotate hook 2 so that its opening faces the contact side, so that hook 2 rotates from the tongue blocking state to the cheek hook state. At this time, the cheek is placed in the opening of hook 2. The corner of the mouth can be pulled by hook 2, which can widen the field of vision of oral operation. At the same time, adjust the angle of the suction tube and place it on the cheek side behind the molars or in the posterior tooth area. This allows for the rapid, stable and timely suctioning of water in the oral cavity.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
