Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a foreign body clamping device specially used in stomatology. Background Art

[0002] Dentistry is one of the medical disciplines. The main dental diseases include oral and maxillofacial dermoids, epidermal submandibular space infection, maxillofacial lymphangioma, odontoid malformation, maxillary sinus malignant tumor, jaw ameloblastoma, chronic ethmoid sinusitis, mandibular retraction, tetracycline teeth, leukoplakia of the tongue, etc. With current technology, many periodontal diseases can be completely cured. The development of tissue bioengineering technology such as guided tissue regeneration technology, gene technology, and implant dentures has brought exciting hope for the regeneration of diseased teeth. However, the treatment of periodontal disease must be a sequential treatment. During the treatment process, a detailed and effective treatment plan, meticulous and exquisite treatment by the doctor, and active cooperation of the patient are the key to treatment. The key to success Most of the existing foreign body removal devices for oral care are very simple devices. They cannot replace the removal needles well, are not convenient for users to remove some foreign bodies in the patient's mouth, increase the labor intensity of users and are not convenient for users to operate. It is not convenient to sterilize and clean the removal needles well, so that the device does not have a good replacement function, cannot remove the debris around the foreign body well, greatly reduces the cleaning effect of the device, is not safe and reliable enough, cannot control the two removal needles well, is not convenient and fast enough, cannot facilitate users to observe the environment inside the patient's mouth, and has poor fixing effect.

[0003] Prior art, such as Chinese patent "CN110811795B", provides a foreign body clamping device for stomatology, including a device body, a hand socket and a clamping device structure. The bottom of the device body is fixedly connected with the hand socket, and the surface of the hand socket is connected to the outer wall of the device body. The top two ends of the device body are fixedly connected with the clamping devices, the interior of the clamping device is connected to the inner wall of the device body, the bottom of the clamping device is fixedly connected with an LED light bar, and the outside of the LED light bar is connected to the inner wall of the clamping device. By setting a freely retractable mechanism, when the doctor needs to retract the needle, one side of the clamping strip is connected to the inner wall of the waist-shaped hole, and through the clamping strip inside the waist-shaped hole inside the device body, the positioning pin on one side of the clamping strip is moved and buckled on the top of the clamping strip for fixing when it needs to be straightened. The fixation of the clamping strip can make the needle on the top of the device body more stable, effectively improving the stability of the device. It is suitable for use in stomatology and has broad development prospects in the future.

[0004] In this scheme, the main body of the device is arranged in a scissor-like X-shape by rotating the position fulcrum of the rotating shaft. This leads to the fact that when clamping an object, if the clamped object is large, the main body of the device needs to be held at one end and opened at a sufficiently large angle to clamp it. However, the internal space of the oral cavity is limited. When the foreign body is located near the deep part of the oral cavity, it will lead to certain restrictions when opening. If the opening range is large, it will cause discomfort to the patient. Therefore, a foreign body clamping device specially used in dentistry is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a foreign body clamping device specially designed for dentistry in order to solve the above-mentioned problems. It is intended to overcome the problem in the prior art that when it is necessary to clamp foreign bodies inside the oral cavity, the clamping device formed by a scissor-type cross mechanism will cause discomfort to the patient when the range of opening in the oral cavity is large. See the following description for details.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides a foreign body clamping device for stomatology, comprising a suction tube, wherein the head of the suction tube is provided with a clamping portion for clamping foreign bodies in a cavity;

[0008] The clamping part is provided with a suction mechanism inside for sucking sputum in the oral cavity;

[0009] A middle block is fixedly connected to the middle position of the inner wall of the draw tube head, and support shafts are fixedly connected to the positions of the inner wall of the draw tube on both sides of the middle block. The outsides of the two support shafts are rotatably connected with swivels, and the outer walls of the swivels are fixedly connected with a chuck. Notches are provided at the positions of the two groups of swivels inside the draw tube, and air-sealing pieces are fixedly connected to the positions of the inside of the draw tube on both sides of the middle block, and ventilation holes are provided on the inner walls of the swivels for connecting the area of ​​the air-sealing piece between the notches with the area of ​​the swivel outside the draw tube, and by providing the ventilation holes, when the swivel rotates, air can be supplemented to the area between the middle block and the notch through the ventilation holes to ensure that the swivel can rotate smoothly. When the oral cavity needs to be clamped When there is a foreign object inside, the air inside the suction tube is extracted to facilitate the generation of negative pressure inside the suction tube. Since a notch is provided on the outer wall of the swivel, negative pressure is generated inside the suction tube, which will drive the swivel to rotate to fill the space at the notch. By providing an air vent, when the swivel rotates, air can be added to the area between the middle block and the notch through the air vent to ensure that the swivel can rotate smoothly, so that the clamps on the outer walls of the two sets of swivels are opened to prepare for clamping. When clamping, air is injected into the suction tube to reset the swivel so that the clamp can clamp the foreign object, so as to avoid the problem that when the clamping device formed by the existing scissor-type cross mechanism opens a large range in the oral cavity to deal with oral foreign objects, it will cause discomfort to the patient.

[0010] Preferably, the clamping surface of the chuck is provided with anti-slip grooves, and the contact surface between the rotating ring and the inner wall of the draw tube is in a fitted and sealed state.

[0011] Preferably, the draw tube consists of a frame and a buckle frame, and the buckle frame is buckled to the outer wall of the frame. By splicing the draw tube with the frame and the buckle frame, it is convenient to clean the inner wall of the draw tube when not in use.

[0012] Preferably, a limit sleeve is provided at a position movable sleeve away from one end of the clamping part, a suction pipe is fixedly connected to the top of the limit sleeve, and a connecting head is fixedly connected to the position of the suction pipe away from one end of the limit sleeve. The limit sleeve is provided at one end of the suction tube to facilitate the fixation of the splicing frame and the buckle frame, so as to improve the sealing and stability of the suction tube when it is used. The sewage pump is connected through the connecting head to facilitate the extraction or injection of air into the inside of the suction tube through the suction pipe, and the clamping part is cooperated for clamping.

[0013] Preferably, a plurality of suction holes are provided on the outer side of the chuck for sucking sputum in the oral cavity.

[0014] Preferably, a circular hole is provided at a position of the middle block away from one end of the chuck, and a sewage extraction channel is provided inside the chuck for connecting the circular hole with the sewage suction hole. When the chuck is opened and prepared for clamping, negative pressure is generated inside the suction tube, which will cause the sewage suction hole to generate a certain adsorption force, so that the patient's sputum enters the sewage suction hole, flows into the suction tube along the sewage extraction channel, and is then discharged from the suction tube, so as to facilitate the suction of the sputum inside the patient's mouth, make the clamping of foreign objects smoother, and avoid the influence of excessive sputum in the patient's mouth on the clamping of foreign objects.

[0015] Preferably, the intermediate block is fixedly connected to a limiting column at a position outside the circular hole, and the outer wall of the limiting column is slidably connected to a piston head.

[0016] Preferably, a spring is provided on the outer wall of the limit column at a position where the piston head is away from the circular hole. By arranging a spring at the circular hole to support the piston head, the circular hole can only be ventilated in one direction, so that when the suction hole is sucking sewage or the chuck is opened, air can be sucked into the interior of the suction cylinder through the circular hole, and air is injected into the suction cylinder. When the chuck is clamped, the tension of the spring will push the piston head to block the circular hole, thereby realizing automatic closure of the circular hole.

[0017] Preferably, the contact surface between the piston head and the circular hole is configured as a conical surface to increase the contact area.

[0018] The beneficial effects are:

[0019] 1. When it is necessary to clamp a foreign object inside the oral cavity, the present invention extracts air from the suction tube to facilitate generating negative pressure inside the suction tube. Since a notch is provided on the outer wall of the rotating ring, negative pressure is generated inside the suction tube, which drives the rotating ring to rotate and supplement the space at the notch. Moreover, by providing an air vent, air can be supplemented to the area between the middle block and the notch through the air vent when the rotating ring rotates, so as to ensure that the rotating ring can rotate smoothly. Moreover, by providing an air vent, air can be supplemented to the area between the middle block and the notch through the air vent when the rotating ring rotates, so as to ensure that the rotating ring can rotate smoothly, so that the clamps on the outer walls of the two groups of rotating rings are opened to prepare for clamping. When clamping, air is injected into the suction tube to reset the rotating ring so as to achieve the clamping of the foreign object by the clamp, so as to avoid the problem that when the clamping device formed by the existing scissor-type cross mechanism is opened to a large extent in the oral cavity for handling oral foreign objects, it will cause discomfort to the patient.

[0020] 2. The present invention arranges a frame body and a buckle frame for splicing the suction tube to facilitate cleaning of the inner wall of the suction tube when not in use, and adopts a limiting sleeve arranged at one end of the suction tube to facilitate fixing the spliced ​​frame body and the buckle frame, so as to improve the sealing and stability of the suction tube when in use, and connects the sewage pump through a connecting head to facilitate extraction or injection of air into the interior of the suction tube through a suction pipe, and cooperates with the clamping part for clamping.

[0021] 3. When the chuck is opened and prepared for clamping, negative pressure is generated inside the suction tube, which will cause the suction hole to generate a certain adsorption force, so that the patient's sputum enters the suction hole, enters the suction tube along the suction channel, and is discharged from the suction tube, so as to facilitate the suction of the sputum inside the patient's mouth, and make the clamping of foreign objects smoother, avoiding the influence of excessive sputum in the patient's mouth on the clamping of foreign objects, and by arranging a spring at the circular hole to support the piston head, the circular hole can only be ventilated in one direction, so that when the suction hole is sucking sewage or the chuck is opened, air can be sucked into the interior of the suction tube through the circular hole, and air is injected into the suction tube, so that when the chuck is clamped, the tension of the spring will push the piston head to block the circular hole, thereby realizing the automatic closure of the circular hole.

The chuck 34 is provided with anti-slip grooves 341 on its clamping surface, and the contact surface between the swivel ring 33 and the inner wall of the draw tube 1 is in a close sealing state to avoid air leakage at the contact position between the swivel ring 33 and the inner wall of the draw tube 1. When it is necessary to clamp foreign objects inside the oral cavity, the air inside the draw tube 1 is extracted to facilitate the generation of negative pressure inside the draw tube 1. Since the outer wall of the swivel ring 33 is provided with a notch 331, negative pressure is generated inside the draw tube 1, which drives the swivel ring 33 to rotate to fill the space at the notch 331 position, and by opening a through hole The air hole 333 allows air to be added to the area between the middle block 31 and the notch 331 through the air hole 333 when the swivel 33 rotates, so as to ensure that the swivel 33 can rotate smoothly, so that the clamps 34 on the outer walls of the two groups of swivels 33 are opened to prepare for clamping.

[0033] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5The pumping tube 1 is composed of a frame 11 and a buckle frame 12, and the buckle frame 12 is buckled on the outer wall of the frame 11. A limiting sleeve 2 is movably sleeved at one end of the pumping tube 1 away from the clamping portion 3. A suction pipe 21 is fixedly connected to the top of the limiting sleeve 2, and a connector 22 is fixedly connected to the position of the suction pipe 21 away from one end of the limiting sleeve 2. The pumping tube 1 is provided with a frame 11 and a buckle frame 12 for splicing, so as to facilitate cleaning of the inner wall of the pumping tube 1 when not in use, and the limiting sleeve 2 is sleeved on one end of the pumping tube 1 to facilitate fixing the spliced ​​frame 11 and the buckle frame 12, so as to improve the sealing and stability of the pumping tube 1 when in use. The sewage pump is connected through the connector 22 to facilitate the extraction or injection of air into the suction tube 1 through the suction pipe 21, and the clamping part 3 is cooperated for clamping. When it is necessary to clamp foreign objects inside the oral cavity, the air inside the suction tube 1 is extracted to facilitate the generation of negative pressure inside the suction tube 1, which will drive the rotating ring 33 to rotate to supplement the space at the position of the notch 331, and by providing the air hole 333, when the rotating ring 33 rotates, the chucks 34 on the outer walls of the two groups of rotating rings 33 are opened to prepare for clamping. When clamping, air is injected into the suction tube 1 to reset the rotating ring 33 so that the chuck 34 can clamp the foreign objects.

[0034] For further information, see Figure 6 , Figure 7 A plurality of suction holes 35 are provided on the outside of the chuck 34 for sucking sputum in the oral cavity. A circular hole 352 is provided at a position of the middle block 31 away from one end of the chuck 34. A suction channel 351 is provided inside the chuck 34 for connecting the circular hole 352 with the suction hole 35. When the chuck 34 is opened and prepared for clamping, negative pressure is generated inside the suction tube 1, which will cause the suction hole 35 to generate a certain adsorption force, so that the patient's sputum enters the suction hole 35, enters the suction tube 1 along the suction channel 351, and is then discharged from the suction tube 21, so as to facilitate the suction of the sputum inside the patient's oral cavity, make the clamping of foreign objects smoother, and avoid the influence of excessive sputum inside the patient's oral cavity on the clamping of foreign objects.

[0035] For further information, see Figure 6 , Figure 7The middle block 31 is fixedly connected to the limiting column 354 at the position outside the circular hole 352, and the outer wall of the limiting column 354 is slidably connected to the piston head 353.

The contact surface between the piston head 353 and the circular hole 352 is set in a conical surface to increase the contact area. By arranging a spring 355 at the circular hole 352 to support the piston head 353, the circular hole 352 can only be ventilated in one direction, so that when the suction hole 35 is sucking sewage or the chuck 34 is opened, air can be sucked into the inside of the suction tube 1 through the circular hole 352, and air is injected into the suction tube 1 so that the chuck 34 is clamped, the tension of the spring 355 will push the piston head 353 to block the circular hole 352, thereby realizing the automatic closure of the circular hole 352.

[0036] How it works

[0037] When in use, the sewage pump is connected through the connector 22 to facilitate the extraction or injection of air into the suction tube 1 through the suction tube 21. When it is necessary to clamp foreign objects in the oral cavity, the air inside the suction tube 1 is extracted to facilitate the generation of negative pressure inside the suction tube 1. Since the outer wall of the rotating ring 33 is provided with a notch 331, the negative pressure generated inside the suction tube 1 will drive the rotating ring 33 to rotate to fill the space at the position of the notch 331, and the vent hole 333 is provided so that when the rotating ring 33 rotates, the air can be passed through the notch 331. Air is added to the area between the middle block 31 and the notch 331 through the vent hole 333 to ensure that the rotating ring 33 can rotate smoothly, so that the clamps 34 on the outer walls of the two sets of rotating rings 33 are opened to prepare for clamping. When clamping, the rotating ring 33 is reset by injecting air into the suction tube 1, so that the clamps 34 can clamp the foreign matter. When the clamps 34 are opened to prepare for clamping, the negative pressure inside the suction tube 1 can be used to make the suction hole 35 have a certain adsorption force, so that the patient's sputum enters the suction hole 35. After that, it enters the suction tube 1 along the suction channel 351 and is discharged from the suction tube 21, so as to facilitate the suction of the sputum in the patient's mouth, making it easier to clamp the foreign body, and avoiding the influence of excessive sputum in the patient's mouth on the clamping of the foreign body. In addition, by arranging a spring 355 at the circular hole 352 to support the piston head 353, the circular hole 352 can only be ventilated in one direction, so that when the suction hole 35 is sucking sewage or the clamp 34 is opened, air can be sucked into the suction tube 1 through the circular hole 352. The inside of the extraction tube 1 is filled with air, and when the chuck 34 is clamped, the tension of the spring 355 pushes the piston head 353 to block the circular hole 352, thereby realizing the automatic closing of the circular hole 352. The extraction tube 1 is provided with a frame body 11 and a buckle frame 12 for splicing, so as to facilitate the cleaning of the inner wall of the extraction tube 1 when not in use, and the limiting sleeve 2 is sleeved on one end of the extraction tube 1 to facilitate the fixation of the spliced ​​frame body 11 and the buckle frame 12, so as to improve the sealing and stability of the extraction tube 1 when in use.
