Description

Technical Field

[0001] The invention belongs to the technical field of oral treatment instruments, and in particular relates to a negative pressure device attached to tooth tissue. Background Art

[0002] During dental procedures such as caries treatment, tooth preparation, periodontal surgery, and implant surgery, saliva, blood, cutting debris, irrigation fluid, and other liquids and particulate matter are produced in the surgical area. These substances must be removed promptly to maintain a clear field of vision and avoid wound contamination and the risk of aspiration. Existing fixation methods mainly rely on hand-held fixation by medical staff or occlusal fixation by the patient. During prolonged operation or complex tooth position treatment, the suction tube is easily displaced by swallowing, tongue movement, etc. Some devices using suction cups or jacket structures either fail to adhere due to saliva contamination on the tooth surface or damage the tooth tissue due to excessive rigidity of the fixing structure, making it impossible to achieve reliable and non-invasive attachment. In existing technologies, conventional suction heads are fixed in position, making it difficult to accommodate suction needs at multiple tooth positions and angles. This is especially true in delicate procedures such as root canal treatment and periodontal surgery, where narrow surgical areas or complex tooth morphologies often result in suction blind spots, leading to residual liquid and debris, affecting the operator's field of view and efficiency. Furthermore, traditional suction devices require frequent manual position adjustments, forcing medical staff to balance instrument operation and suction control, increasing the burden on the operator. Furthermore, the disassembly process of the fixed device is cumbersome, making it impossible to quickly switch suction positions during surgery, reducing surgical continuity. Therefore, in order to solve the above-mentioned problems in the prior art, the present invention proposes a negative pressure device attached to the tooth tissue. Summary of the Invention

[0003] In order to solve the above-mentioned problems of the prior art, the present invention designs a negative pressure device attached to the tooth tissue, which is connected by sliding a suction slide at the lower end of the attachment block and providing an attachment slide groove inside. By pushing the suction slide, the attachment slide is pushed to the patient's tooth to clamp and attach the patient's tooth, and by pulling the suction slide, the release block at the front end pushes the limit block, so that the attachment slide slide slides out and releases the clamping of the patient's tooth. At the same time, auxiliary suction rods are symmetrically arranged on both sides of the suction slide to rotate, and by controlling the rotation of the auxiliary suction rods, suction is applied to different positions in the oral cavity. In order to achieve the above technical effects, the present invention is implemented through the following technical solutions: a negative pressure device attached to tooth tissue, comprising: a suction slide, an attachment block; The lower end of the attachment block is slidably connected to the suction slide; An attachment plate is provided at the upper front end of the attachment block, and a suction chute is provided at the lower end thereof for sliding connection with the suction slide; attachment chutes are provided on both sides of the upper end of the suction chute for sliding connection with the attachment slide, a plurality of limit grooves are provided in an internal array, and a release chute is provided at the front and rear ends of the middle portion; a limit plate is provided in the middle of the front end of the attachment slide; a limit block is provided at the front end of the limit plate for movably connecting with the limit groove; Furthermore, the release chute depth is greater than the limiting groove depth; Furthermore, a release push plate is provided at the middle of the front end of the suction slide, a push block movably connected to a limit plate is provided at the rear end, and a release groove movably connected to the limit plate is provided between the contact push plate and the push block; a release slide groove movably connected to the release block is provided at the front end of the release push plate; Furthermore, the cross-sections of the release block and the limit block are both triangular, and the inclined surfaces of the two are tangent; Furthermore, the push block and the release push plate have the same width and are both slidably connected to the release chute; Furthermore, the width of the limit plate is greater than that of the release push plate; Furthermore, the inner surfaces of the attachment plate and the attachment slide plate are both provided with a silicone plate to improve the stability of the fixation; Furthermore, a negative pressure chamber is provided inside the rear end of the suction slide, a negative pressure tube is provided outside to connect to the negative pressure mechanism, a main suction rod is provided in the middle of the front end, and holes are provided on both sides to rotatably connect to the auxiliary suction rod; a pulley is provided in the middle of the auxiliary suction rod, and a sealing ring is provided at the rear end to rotatably connect to the suction slide; Furthermore, adjustment openings are symmetrically provided on both sides of the middle portion of the suction slide for slidingly connecting pulleys.

[0004] The beneficial effects of the present invention are: The present invention slides and connects the suction slide at the lower end of the attachment block. Pushing the suction slide allows the attachment slide to clamp the tooth tissue, while pulling the suction slide releases the clamping. This not only achieves stable attachment but also enables rapid switching of suction positions during surgery, ensuring the continuity of the surgery. In addition, the silicone sheet provided on the inner surface of the attachment plate and the attachment slide further improves the stability of fixation and prevents adsorption failure due to saliva contamination of the tooth surface. At the same time, by symmetrically rotating auxiliary suction rods on both sides of the suction slide, medical staff can control the rotation of the auxiliary suction rods to suction different positions in the oral cavity, effectively solving the problem that conventional suction heads are difficult to take into account the suction needs of multiple teeth and multiple angles, eliminating the suction blind spots in narrow surgical areas or complex tooth morphologies, reducing liquid and debris residue, ensuring a clear operating field of view, and improving surgical efficiency.

[0007] The present invention discloses a negative pressure device attached to tooth tissue, comprising: a suction slide 1, an attachment block 3; The lower end of the attachment block 3 is slidably connected to the suction slide 1; An attachment plate 4 is provided at the upper front end of the attachment block 3, and a suction slide 20 is provided at the lower end to be slidably connected to the suction slide 1; attachment slides 7 are provided on both sides of the upper end of the suction slide 20 to be slidably connected to the attachment slide 5, a plurality of limit grooves 9 are provided in the internal array, and a release slide 8 is provided at the front and back of the middle; a limit plate 17 is provided in the middle of the front end of the attachment slide 5; a limit block 16 is provided at the front end of the limit plate 17 to be movably connected to the limit groove 9; pushing the suction slide 1 can make the attachment slide 5 clamp the tooth tissue, and pulling the suction slide 1 can release the clamping, which not only realizes stable attachment, but also realizes rapid switching of the suction position during the operation, thereby ensuring the continuity of the operation.

[0008] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0009] Example 1 like Figure 1-6 As shown, the lower end of the attachment block 3 is slidably connected to the suction slide 1; An attachment plate 4 is provided at the upper front end of the attachment block 3, and a suction chute 20 is provided at the lower end to be slidably connected to the suction slide 1; attachment chutes 7 are provided on both sides of the upper end of the suction chute 20 to be slidably connected to the attachment slide 5, a plurality of limit grooves 9 are provided in an array inside, and a release chute 8 is provided in the front and rear parts of the middle; a limit plate 17 is provided in the middle of the front end of the attachment slide 5; a limit block 16 is provided at the front end of the limit plate 17 to be movably connected to the limit groove 9; The attachment chute 7 runs through both sides of the upper end of the suction chute 20 and is slidably connected to the attachment slide 5, so that the attachment slide 5 can move within a certain range. When the suction slide 1 is pushed, the attachment slide 5 moves in the attachment chute 7, and the limit block 16 is embedded in the limit groove 9, thereby fixing the attachment slide 5 in a specific position to achieve clamping and fixing of the tooth tissue. Different fixing position options are provided through multiple limit grooves 9 to adapt to different tooth shapes and positions; Furthermore, the depth of the release chute 8 is greater than the depth of the limiting groove 9; When the clamping of the tooth body needs to be released, the release chute 8 with sufficient depth can accommodate the movement of the release block 18, and push the limit block 16 into the release groove 12 through the contact of the inclined surface, thereby ensuring a smooth release operation and preventing the limit block 16 from getting stuck in the limit groove 9; Furthermore, a release push plate 13 is provided in the middle of the front end of the suction slide 1, a push block 10 is provided at the rear end to be movably connected to a limit plate 17, and a release groove 12 is provided between the contact push plate and the push block 10 to be movably connected to the limit plate 17; a release block 18 is provided at the front end of the release push plate 13 to be movably connected to the release chute 8; Furthermore, the cross-sections of the release block 18 and the limit block 16 are both triangular, and the oblique surfaces of the two are tangent; utilizing the characteristics that the cross-sections of the release block 18 and the limit block 16 are triangular and the oblique surfaces are tangent, the limit block 16 is pushed out of the limit groove 9, so that the attachment slide 5 can slide out of the attachment slide 7, releasing the clamping of the tooth body, the push block 10 and the release push plate 13 have the same width and are both slidably connected to the release slide 8, ensuring that the force can be evenly transmitted when the suction slide 1 is pulled, making the release operation stable and reliable; the width of the limit plate 17 is greater than the release push plate 13, ensuring that the limit plate 17 is fully in contact with the limit groove 9, preventing fixation failure, and maintaining the stability of the structure.

[0010] Furthermore, the push block 10 and the release push plate 13 have the same width and are both slidably connected to the release chute 8; Furthermore, the width of the limit plate 17 is greater than the release push plate 13; Furthermore, a silicone plate 6 is provided on the inner surface of the attachment plate 4 and the attachment slide plate 5 to improve the stability of fixation. The adhesive material has good flexibility and anti-slip properties. When clamping the tooth tissue, the silicone plate 6 can closely fit the tooth surface, increase friction, and improve the stability of fixation. At the same time, the softness of the silicone will not cause damage to the tooth, thus achieving non-traumatic fixation. Furthermore, a negative pressure chamber 21 is provided inside the rear end of the suction slide 1, a negative pressure tube 2 is provided outside to connect to the negative pressure mechanism, a main suction rod 11 is provided in the middle of the front end, and holes are provided on both sides to rotatably connect to the auxiliary suction rod 14; a pulley 15 is provided in the middle of the auxiliary suction rod 14, and a sealing ring 19 is provided at the rear end to rotatably connect to the suction slide 1; Furthermore, the adjustment openings 22 are symmetrically provided on both sides of the middle portion of the suction slide 1 and are slidably connected to the pulley 15; In this embodiment, when the device is in use, when the suction slide 1 is pushed to slide forward, the suction slide 1 drives the attachment slide 5 to move toward the tooth through the push block 10, so that the attachment plate 4 and the attachment slide 5 respectively clamp the tooth; the limit block 16 at the front end of the attachment slide 5 is embedded in the limit groove 9 inside the attachment block 3, and the position is fixed by the self-locking property of the triangular inclined surface to form a stable clamping; the silicone plate 6 is attached to the tooth surface, and the friction and flexible contact enhance the fixation stability and avoid rigid damage; When contact fixation is required, when the suction slide 1 is pulled to slide backward, the release push plate 13 at the front end of the suction slide 1 drives the release block 18 to move in the release chute 8. Since the release block 18 is tangent to the triangular inclined surface of the limit block 16, the release block 18 pushes the limit block 16 to move outward when it moves backward, disengaging from the limit groove 9, so that the attachment slide 5 loses its constraint and slides out of the attachment chute 7, releasing the clamping of the tooth body; The negative pressure chamber 21 is connected to the external negative pressure mechanism through the negative pressure tube 2 to form a negative pressure power source. The main suction rod 11 is located in the middle of the front end and is directly aimed at the center of the surgical area to absorb the main liquid and debris. The auxiliary suction rods 14 on either side are slidably connected to the adjustment port 22 via pulleys 15 and can rotate around the connection holes. Medical personnel push the pulleys 15 to slide within the adjustment port 22, changing the position of the front end of the auxiliary suction rods 14 to cover multiple tooth positions and angles, eliminating blind spots in suction. Sealing rings 19 ensure airtightness during rotation of the auxiliary suction rods 14, preventing negative pressure leaks that could affect the suction effect.

[0011] Example 2 In this embodiment, in actual use, the front ends of the main suction rod 11 and the auxiliary suction rod 14 can be set as a multi-angle suction rod structure; Anterior teeth: The labial and lingual spaces of the crown are relatively open, but the interproximal spaces are narrow. The suction rod needs to be able to penetrate the interproximal surfaces without blocking the field of vision. Posterior teeth: The deep oral cavity is narrow, especially the mandibular molars, which are close to the tongue root on the lingual side. The suction rod needs to go around the tongue or buccal fat pad, and the angle needs to be steeper to penetrate deeper into the surgical area. Delicate areas such as periodontal pockets and root canals: The tip of the suction rod must be close to the tooth surface or root canal wall at an acute angle to avoid vertical angles that may cause the suction port to be blocked by tissue; Main suction rod 11: 90°~105° is the reference angle: 90° right-angle setting: Suitable for operation under direct vision in the anterior teeth area. The suction rod is perpendicular to the long axis of the tooth and can be directly aimed at the central area such as cavities and caries lesions. The suction path is short and the efficiency is high. Application scenarios: routine operations such as caries filling and tooth preparation, especially suitable for the labial side of maxillary anterior teeth or the lingual side of mandibular anterior teeth; 100°~105° slightly obtuse angle setting: In the posterior tooth area, the slightly obtuse angle can tilt the tip of the suction rod outward to avoid obstruction by the buccal muscle or tongue, while maintaining an effective distance between the suction port and the surgical area to avoid blockage caused by close contact with the tissue; Application scenarios: Periodontal surgeries such as flap surgery and implant surgery that require deep subgingival or bone surface operations; Auxiliary suction rod 14: 80°~110° angle setting: 80°~90° acute angle setting: used in narrow spaces, the tip can penetrate into the interproximal space or the side of the root canal wall, fit the edge of the tooth surface at an acute angle, and remove residual debris; 100°~110° obtuse angle design: suitable for covering the tooth axis at multiple angles, especially when multiple teeth need to be sucked at the same time, the obtuse angle allows the auxiliary suction rod 14 to cover a wider range and reduce the number of repeated adjustments; In actual use, the main suction rod 11 and the auxiliary suction rod 14 can be set at multiple angles and flexibly replaced according to different surgical sites and surgical types to improve the suction efficiency during surgery.

[0012] In summary, the present invention achieves stable attachment and rapid switching of suction positions during surgery by slidingly connecting the suction slide 1 at the lower end of the attachment block 3. Pushing the suction slide 1 allows the attachment slide 5 to clamp the tooth tissue, while pulling the suction slide 1 releases the clamping. This ensures the continuity of the surgery. Furthermore, the silicone sheet 6 provided on the inner surfaces of the attachment plate 4 and the attachment slide 5 further enhances the stability of fixation and prevents adsorption failure due to saliva contamination of the tooth surface. At the same time, by symmetrically rotating the auxiliary suction rods 14 on both sides of the suction slide 1, medical staff can control the rotation of the auxiliary suction rods 14 to suction different positions in the oral cavity, effectively solving the problem that conventional suction heads are difficult to take into account the suction needs of multiple tooth positions and multiple angles, eliminating the suction blind spots in narrow surgical areas or complex tooth morphologies, reducing liquid and debris residue, ensuring a clear operating field of view, and improving surgical efficiency.
