Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental instruments, specifically to a dental surgical saliva suction device with lighting function. Background Technology
[0002] During alveolar surgery (such as complex tooth extraction, alveolar bone trimming, cyst curettage, etc.), a mixture of saliva, blood, and cooling water is continuously produced in the surgical area. To maintain a clear surgical field and prevent aspiration, a saliva aspirator must be used to remove these fluids promptly. Existing saliva aspirators typically consist of a suction head, connecting tube, and negative pressure generator, and their function is singular, providing only suction.
[0003] However, the internal structure of the oral cavity is complex, especially in areas such as the mandibular molar region, which are deep and difficult for natural light to penetrate directly. During surgery, doctors mainly rely on independent external surgical lights for illumination. This lighting method has significant shortcomings: First, the light from external surgical lights is easily blocked by the doctor's head, arms, or surgical instruments, creating shadows in the surgical area and causing a temporary darkening of the field of vision; second, for the deep and narrow alveolar sockets formed after tooth extraction, the internal lighting is severely insufficient, and the illumination angle of conventional surgical lights is insufficient to directly illuminate the bottom of the socket, making it extremely difficult for doctors to explore residual tooth fragments, granulation tissue, or assess the integrity of the bone wall within the alveolar socket, greatly affecting the precision and safety of the surgery.
[0004] While some mouth openers or hooks with independent light sources exist, they cannot solve the problem of the suction device itself blocking light. As an instrument that must be placed near the surgical area, the tube of the suction device is often one of the main causes of shadows. Therefore, there is an urgent need for an integrated instrument that can organically combine lighting and suction functions to fundamentally solve the lighting problem in the surgical area, especially in deep alveolar sockets. Utility Model Content

[0010] Preferably, the handheld part 2 of the suction tube 1 is further provided with a clearing mechanism for clearing blockages in the suction channel 4; the clearing mechanism includes a clearing operation tube 7, which is located at the top of the handheld part 2 and has a clearing channel 71 inside that communicates with the suction channel 4. The clearing channel 71 is divided into a parallel section 711 parallel to the handheld part 2 and an arc-shaped section 712 that communicates with the arc-shaped connection between the suction part 3 and the handheld part 2. A clearing push rod 8 is inserted into the clearing channel 71. The clearing push rod 8 is a plastic rod that can be bent elastically; the clearing push rod 8 is inserted into the suction channel 4 of the suction part 3 along the arc-shaped section 712 of the clearing channel 71.
[0011] Preferably, the inner wall of the arc-shaped section 712 in the unblocking channel 71 is provided with a rubber sealing ring, and the unblocking push rod 8 slides in the rubber sealing ring to maintain the sealed isolation between the suction channel 4 and the unblocking channel 71.

[0016] The beneficial effects of this utility model are: 1. This invention integrates a ring-shaped lighting module on the side wall of the suction tube head and innovatively sets up spaced-apart ring-shaped focusing and floodlight units, achieving integration of the light source and suction function. This design solves the problem of traditional external surgical lights easily being blocked by the surgeon's head or instruments, creating shadows. Surgeons can flexibly select the lighting mode via the light source control switch according to the needs of different stages of surgery: the focusing mode uses a convex lens to converge light, forming a high-brightness, highly penetrating beam, specifically designed to illuminate the bottom of deep, narrow alveolar sockets, facilitating clear observation of residual tooth fragments, granulation tissue, and bone wall conditions, significantly improving surgical precision and safety. The floodlight mode uses a ground glass or Fresnel lens to diffuse light, forming a wide-range, soft illumination, suitable for observing larger surgical areas, such as extraction wounds of multiple teeth or soft tissue incisions, providing a uniform, glare-free field of view. Simultaneous activation of both modes provides higher brightness and more comprehensive lighting effects, meeting the lighting needs of complex surgical situations.
[0017] 2. To address the problem of saliva suction devices easily becoming clogged by blood clots and tissue debris during surgery, this invention incorporates a push-rod piston-type unblocking mechanism in the handheld part. The unblocking push rod directly pushes the obstruction out of the suction port, making operation simple, responsive, and significantly reducing surgical interruption time.

[0026] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0027] like Figure 1-8 As shown, this utility model provides a dental surgical saliva suction device with lighting function, which mainly includes three parts: suction tube 1, lighting module 5, and unclogging mechanism.
[0028] The saliva suction tube 1 is a medical-grade transparent or semi-transparent plastic component molded in one piece. It has an ergonomically designed curved structure, divided into a handle 2 and a suction section 3 at the bend. The front end of the suction section 32 is the suction port, and the rear end of the handle 2 is the insertion port for connecting to the negative pressure tube. A continuous suction channel 4 is formed inside the handle, from the suction port to the insertion port. The outer surface of the handle is equipped with a non-slip textured grip 21 for a secure hold by the doctor.
[0029] The lighting module 5 is integrated and installed on the side wall of the head of the suction part 3. It is annular in shape and tightly fitted and fixed to the suction part 3. The annular lighting module 5 is provided with spaced-apart, ring-distributed focusing light source units 51 and floodlight light source units 52. Specifically, the focusing light source unit 51 includes a first LED bead 511 and a first optical lens 512 fixed to the annular sleeve via a connecting bracket 53. The first optical lens 512 is a convex lens, and its optical axis is parallel to the axis of the suction part 3, used to focus the light emitted by the first LED bead 511 into a focused beam. The floodlight light source unit 52 includes a second LED bead 521 and a second optical lens 522 fixed to the lighting module 5 via a connecting bracket 53. The second optical lens 522 is a frosted lens (in another embodiment, a Fresnel lens may also be used), used to diffuse the light emitted by the second LED bead 521 into a floodlight beam.
[0030] A light source control switch 6 is embedded in the outer wall of the handheld part 2. In this embodiment, the switch is a three-position toggle switch with three switching states: toggling forward activates only the spotlight unit 51 (first LED bead 511), toggling backward activates only the floodlight unit 52 (second LED bead 521), and when in the middle position, both the spotlight and floodlight units 52 are activated simultaneously. To ensure power supply, a wiring channel 61 is provided inside the handheld part 2, through which wires are laid to connect the light source control switch 6 to each LED bead. The internal cavity of the light source control switch 6 encapsulates a battery (such as a rechargeable lithium polymer battery) and a control circuit board, which is used to implement stable constant current drive and mode switching logic for the light source.
[0031] The unblocking mechanism is located at the top of the handheld part 2. It includes an unblocking operation tube 7 integrally formed with the handheld part 2. The unblocking operation tube 7 has an unblocking channel 71 inside, which is divided into a parallel section 711 parallel to the handheld part 2 and an arc-shaped section 712 communicating with the arc-shaped bend of the suction tube 1. An unblocking push rod 8 is inserted into the unblocking channel 71. The unblocking push rod 8 is made of elastically bendable medical-grade plastic (such as polyurethane), which allows it to pass smoothly through the arc-shaped section 712 and be inserted into the suction channel 4 of the suction part 3.
[0032] To ensure a tight seal, a rubber sealing ring is embedded in the inner wall of the arc-shaped section 712 of the unblocking channel 71. The unblocking push rod 8 slides within the rubber sealing ring, thereby maintaining a sealed isolation between the suction channel 4 and the unblocking channel 71, ensuring that the suction negative pressure does not leak.
[0033] At the junction of the parallel section 711711 and the arc-shaped section 712712 of the unblocking channel 7171, an annular limiting step 713 is formed. A limiting piece 81 is fixed to the rear end of the unblocking push rod 8. A return spring 9 is sleeved on the unblocking push rod 88, with its two ends respectively pressing against the limiting step 713 and the limiting piece 81. On the side wall of the unblocking operation tube 7, a groove 72 communicating with the parallel section 711 of the unblocking channel 71 is provided. A push block 73 passes through the groove 72 and is connected to the limiting piece 81 of the unblocking push rod 8. The doctor can move the unblocking push rod 8 forward by pushing the push block 73 with his thumb.
[0034] Because the diameter of the unblocking channel 10 set in the suction channel 4 is smaller, when a blockage occurs, it can only occur in the unblocking channel 10, thus making it easier to use the unblocking push rod 8 to unclog the unblocking channel 10.
[0035] The working process of this utility model is as follows: Connect the external negative pressure tube to the insertion port. Select the lighting mode: toggle the light source control switch 6 according to the surgical needs. Select the focused light mode when exploring deep alveolar sockets; select the floodlight mode when observing a large surgical field. Insert the suction unit 3 into the vicinity of the surgical area in the patient's mouth and perform normal saliva and blood suction operations. If blockage occurs, the doctor can use their thumb to push the push block 73 on the blockage removal tube 7 forward. The push block 73 drives the blockage removal push rod 8 to move forward against the elastic force of the reset spring 9. The front end of the blockage removal push rod 8 passes through the arc-shaped section 712 of the blockage removal channel 71 in sequence, and finally extends into the suction channel 4 of the suction unit 3, pushing the blockage out of the suction port. After releasing the push block 73, the blockage removal push rod 8 automatically retracts to the initial position under the action of the reset spring 9, without affecting normal suction.
[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
