Description

Technical Field

[0001] This invention relates to the field of dental medical device technology, and in particular to a minimally invasive, painless tooth extraction forceps. Background Technology

[0002] Currently, tooth extraction is very common in oral healthcare. It is the most basic dental procedure. Among the procedures, extraction forceps are the most frequently used in dental surgery. Extraction forceps are instruments used to grasp the crown or root of a tooth and loosen and dislocate the tooth through wedging, shaking, twisting, and traction.

[0003] Traditional tooth extraction forceps often require considerable force to remove teeth, which can easily cause significant trauma to surrounding tissues such as the gums and alveolar bone. This results in severe pain for patients during the extraction process, a longer recovery time, and the potential for complications such as infection and swelling.

[0004] Currently, although there are some so-called minimally invasive tooth extraction tools, their minimally invasive and painless effects are not ideal in practical applications. Some tools have complex structures and are inconvenient to operate, increasing the difficulty for doctors. Other tools lack stability when clamping teeth, which can easily lead to tooth breakage or slippage, further aggravating the patient's pain and trauma. In addition, the clamping parts of existing tooth extraction forceps are mostly fixed structures. When faced with different types and sizes of teeth or when the clamping parts are worn, the entire extraction forceps needs to be replaced, resulting in poor versatility. This not only increases medical costs but also reduces operational efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of poor efficacy, inconvenient operation, and high cost and low efficiency caused by the inability to flexibly replace the clamping parts of traditional minimally invasive tooth extraction forceps, and to propose a minimally invasive painless tooth extraction forceps.

[0006] To achieve the above objectives, the present invention employs the following technology: a minimally invasive painless tooth extraction forceps comprising two symmetrically arranged forceps bodies, each forceps body consisting of a handle and a head, the two forceps bodies being movably connected by a connecting shaft, the forceps bodies being provided with a minimally invasive painless component, the end of the head being provided with a minimally invasive clamping part, one end of the minimally invasive clamping part being provided with a quick-release mechanism, the head and the minimally invasive clamping part being quickly disassembled and assembled via the quick-release mechanism, and the handle being provided with an adjustment component.

[0007] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the minimally invasive painless component includes a pressure sensor and a temperature sensor disposed inside the forceps head, and a display screen disposed on the forceps handle, wherein a mounting groove is provided on one side of one of the forceps handles, and a battery is disposed in the mounting groove, and a battery cover is disposed at the opening of the mounting groove on the forceps handle.

[0008] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the pressure sensor, temperature sensor, and display screen are all electrically connected to the battery.

[0009] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the adjustment assembly includes an adjustment screw and an adjustment nut, one end of the adjustment screw is fixedly connected to one of the forceps handles, the other end passes through the through hole of the other forceps handle and is threadedly connected to the adjustment nut, and a second spring is provided between the two forceps handles and sleeved on the adjustment screw.

[0010] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the quick-release mechanism includes a docking block fixed to one end of the minimally invasive clamping part, a docking groove opened on one side of the forceps head, and a locking component provided on one side of the forceps head. A slot is opened on one side of the docking groove, and a permanent magnet is provided in the slot. An iron insert block adapted to the slot is fixedly connected to one side of the docking block. Conductive contacts are respectively provided on the contact surfaces of the docking block and the docking groove.

[0011] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the locking assembly includes a fixing plate fixed to the forceps head and a locking hole opened on the mating block. A through groove is opened on one side of the fixing plate, and a guide rod is provided in the through groove. A first spring is sleeved on both ends of the guide rod. A lever is movably sleeved on both ends of the guide rod. A connecting rod is fixedly connected to the side of the two levers that are far apart from each other. A connecting plate is fixedly connected to one end of the connecting rod, and a locking rod that matches the locking hole is fixedly connected to the connecting plate.

[0012] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the inner side of the minimally invasive clamping part is provided with anti-slip texture, the minimally invasive clamping part is made of medical stainless steel, and its end is arc-shaped, and the curvature of the arc is adapted to the shape of the tooth.

[0013] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: the anti-slip texture consists of staggered raised strips, the height of which is 0.1-0.3mm.

[0014] As a further description of the aforementioned minimally invasive painless tooth extraction forceps: anti-slip grooves are provided on the outer side of the forceps handle.

[0015] In summary, due to the adoption of the above-mentioned technology in this minimally invasive and painless tooth extraction forceps, the beneficial effects of this invention are: 1. This invention features an arc-shaped minimally invasive clamping part at the tip of the forceps, with anti-slip texture on the inner side. This design allows for stable clamping of teeth, reducing slippage and damage during clamping. The arc shape also conforms to the tooth's shape, minimizing trauma to the gums and surrounding tissues, thus achieving minimally invasive operation. The inclusion of pressure and temperature sensors enables real-time monitoring of clamping pressure and contact temperature, displayed intuitively on a screen. Doctors can adjust the operation based on the monitoring data, avoiding additional pain and damage to the patient due to excessive pressure or temperature, achieving painless tooth extraction. The quick-release mechanism facilitates rapid assembly and disassembly of the minimally invasive clamping part, allowing for flexible replacement according to different tooth types, sizes, and clamping part conditions. This not only reduces medical costs but also improves operational efficiency, while facilitating sterilization of the clamping part and reducing the risk of cross-infection.

[0016] 2. This invention, through its adjustable components, allows for flexible adjustment of the forceps head's opening degree according to the size and position of different teeth. Whether it's a child's deciduous teeth, an adult's permanent teeth, or wisdom teeth in special positions, the appropriate clamping range can be obtained through adjustment, greatly improving the applicability of the extraction forceps. Secondly, the dentist can pre-adjust the forceps head's opening degree before operation, eliminating the need to painstakingly adapt to different tooth sizes during operation, simplifying the procedure and improving convenience and efficiency. In addition, a suitable opening degree allows the minimally invasive clamping part to more accurately conform to the tooth, avoiding unstable clamping or excessive compression of surrounding tissues due to improper opening degree, further reducing trauma and patient pain.

[0019] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a minimally invasive and painless tooth extraction forceps of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a minimally invasive, painless tooth extraction forceps. Please refer to [link / reference]. Figure 1-6 As shown, it includes two symmetrically arranged clamp bodies. Each clamp body consists of a handle 1 and a head 2. The outer side of the handle 1 is provided with an anti-slip groove. The two clamp bodies are movably connected by a connecting shaft 3. The clamp bodies are provided with a minimally invasive painless component. The end of the head 2 is provided with a minimally invasive clamping part 4. One end of the minimally invasive clamping part 4 is provided with a quick-release mechanism 5. The head 2 and the minimally invasive clamping part 4 can be quickly disassembled and assembled through the quick-release mechanism 5. The handle 1 is provided with an adjustment component 6.

[0021] In this embodiment, the minimally invasive clamping part 4 is bent at an angle of 120-150 degrees to the forceps head 2. This angle design is to adapt to the spatial structure inside the oral cavity and the angle of tooth growth. When the doctor holds the forceps handle 1 to operate, this angle allows the minimally invasive clamping part 4 to fit more naturally against the side of the tooth, reducing interference with other oral tissues, facilitating precise clamping of teeth in a narrow oral space, and reducing the difficulty of the doctor's hand exertion during operation, improving the comfort and stability of the operation. During tooth extraction, when encountering different types of teeth such as deciduous teeth, permanent teeth, wisdom teeth, etc., or teeth of different sizes, or when the minimally invasive clamping part 4 is worn or contaminated, the quick-release structure of the minimally invasive clamping part 4 facilitates disassembly and replacement. The end of the forceps head 2 is provided with an arc-shaped minimally invasive clamping part 4, and the inner side of the minimally invasive clamping part 4 is provided with anti-slip texture 11, which can stably... The forceps effectively clamps teeth, reducing slippage and damage during the clamping process. Its curved design conforms to the tooth's shape, minimizing trauma to the gums and surrounding tissues, thus enabling minimally invasive procedures. The adjustable component 6 allows for flexible adjustment of the forceps head 2's opening angle based on the size and position of different teeth. Whether it's a child's deciduous tooth, an adult's permanent tooth, or a wisdom tooth in a special position, the appropriate clamping range can be achieved through adjustment, significantly expanding the applicability of the extraction forceps. Furthermore, the dentist can pre-adjust the opening angle of the forceps head 2 before operation, eliminating the need to adapt to different tooth sizes during the procedure, simplifying the process and improving convenience and efficiency. Additionally, a suitable opening angle allows the minimally invasive clamping part 4 to more precisely conform to the tooth, preventing unstable clamping or excessive compression of surrounding tissues due to improper opening angle, further reducing trauma and patient discomfort.

[0022] Furthermore, the minimally invasive painless component includes a pressure sensor 12 and a temperature sensor 13 disposed inside the forceps head 2, and a display screen 7 disposed on the forceps handle 1. One side of the forceps handle 1 has an installation groove, and a battery 9 is disposed in the installation groove. A battery cover 8 is disposed at the opening of the installation groove on the forceps handle 1. The pressure sensor 12, the temperature sensor 13, and the display screen 7 are electrically connected to the battery 9 respectively.

[0023] In use, the forceps handle 1 is equipped with a control button, and each forceps head 2 is equipped with a pressure sensor 12 and a temperature sensor 13. The sensor sensing end on each forceps head 2 is close to the corresponding minimally invasive clamping part 4. This arrangement can detect the pressure and temperature of the two minimally invasive clamping parts 4 when they come into contact with the teeth, making the detection data more comprehensive and accurate. Doctors can adjust the clamping state in time according to the difference in data on both sides to ensure that the teeth are subjected to uniform force and avoid local tissue damage caused by excessive pressure or temperature on one side. When the minimally invasive clamping part 4 comes into contact with the teeth, the clamping pressure is transmitted to the forceps head 2. The pressure sensor can detect the clamping pressure by sensing the slight deformation of the forceps head 2. At the same time, the temperature generated by the contact between the minimally invasive clamping part 4 and the teeth and surrounding tissues is conducted to the forceps head 2. The temperature sensor can detect the temperature of the contact area by sensing the temperature change of the forceps head 2, and then display the relevant data on the display screen 7. Doctors can adjust the clamping force according to the pressure value on the display screen 7 to avoid damage to the teeth and surrounding tissues due to excessive pressure. Temperature sensor 13 can detect the temperature of the contact area between the forceps 2 and the tooth and surrounding tissues during tooth extraction in real time and display the temperature value on the display screen 7. During tooth extraction, when there is chronic inflammation or periapical lesions in the tooth, the tooth and surrounding tissues may be in a relatively high temperature state. In addition, if the doctor holds the tooth for a long time or the forceps 2 rubs against the tooth, gums and other tissues frequently, the temperature of the contact area will also rise. When the temperature is too high, the doctor can take timely measures, such as pausing the operation to cool the local area or adjusting the clamping method to reduce friction, to prevent the tissue from being burned by high temperature and avoid causing additional pain and damage to the patient.

[0024] Furthermore, the adjustment assembly 6 includes an adjustment screw 61 and an adjustment nut 63. One end of the adjustment screw 61 is fixedly connected to one of the clamp handles 1, and the other end passes through the through hole 62 of the other clamp handle 1 and is threadedly connected to the adjustment nut 63. A second spring 10 is provided between the two clamp handles 1 and sleeved on the adjustment screw 61.

[0025] In this system, when the dentist releases pressure on the forceps handle 1, the second spring 10 uses its own elastic force to push the two forceps handles 1 in opposite directions, causing the forceps head 2 and the minimally invasive clamping part 4 to automatically open. This eliminates the need for manual opening by the dentist, simplifying the operation and allowing the dentist to focus more on the tooth extraction procedure. This is especially beneficial when processing multiple teeth consecutively, effectively improving operational efficiency. Furthermore, the elastic force of the second spring 10 is carefully designed to ensure smooth repositioning of the forceps without creating excessive resistance to the pressure applied by the dentist when clamping the teeth, ensuring smooth clamping operation. The diameter of the through hole 62 is slightly larger than the diameter of the adjusting screw 61, allowing the adjusting screw 61 to pass through smoothly. The outer wall of the end through which the screw passes has an external thread that matches the internal thread of the adjusting nut 63. Rotating the adjusting nut 63 allows adjustment of the distance between the two forceps handles 1. It should be noted that the function of the adjusting component 6... Before tooth extraction, the initial distance between the two forceps handles 1 is pre-adjusted according to the size and position of the tooth, so that the forceps head 2 has a suitable initial opening degree for better alignment and initial clamping of the tooth. When performing the pressing and clamping tooth extraction operation, the doctor holds the two forceps handles 1 and applies pressure. At this time, the connecting shaft 3 acts as a fulcrum, and the forceps head 2 closes to clamp the tooth. The adjusting screw 61 slides in the through hole 62 of the other forceps handle 1 as the forceps handle 1 moves, thus providing guidance for the relative movement of the two forceps handles 1. This ensures that the forceps handle 1 moves in the predetermined direction during the pressing process, avoiding deviation and ensuring that the forceps head 2 can accurately clamp the tooth. After the initial distance is pre-adjusted, the adjusting nut 63 can fix the initial distance to prevent unexpected changes in the opening degree of the forceps head 2 during tooth alignment, improve the stability of the operation, and work together with the pressing operation to make the tooth extraction process more precise and stable.

[0026] Furthermore, the quick-release mechanism 5 includes a docking block 51 fixed to one end of the minimally invasive clamping part 4, a docking groove 52 opened on one side of the clamp head 2, and a locking component 56 provided on one side of the clamp head 2. A slot 54 is opened on one side of the docking groove 52, and a permanent magnet 55 is provided in the slot 54. An iron insert 53 adapted to the slot 54 is fixedly connected to one side of the docking block 51. Conductive contacts are respectively provided on the contact surfaces of the docking block 51 and the docking groove 52. The locking component 56 includes a fixing plate 561 fixed on the clamp head 2. The fixing plate 561 has a locking hole 569 on one side, a through groove 562 on one side, a guide rod 563 in the through groove 562, a first spring 564 on both ends of the guide rod 563, a lever 565 movably connected to both ends of the guide rod 563, a connecting rod 566 fixedly connected to the side of the two levers 565 that are far apart from each other, a connecting plate 567 fixedly connected to one end of the connecting rod 566, and a locking rod 568 that matches the locking hole 569 fixedly connected to the connecting plate 567.

[0027] In use, after the minimally invasive clamping part 4 is installed in place, the conductive contacts make contact with each other, forming an electrical connection between the minimally invasive clamping part 4 and the pressure sensor 12 and temperature sensor 13 inside the clamp head 2, ensuring that the sensors can detect and transmit data normally. During installation, first, the levers 565 are spread open to both sides, causing the two locking rods 568 to move outward relative to each other, inserting the docking block 51 of the minimally invasive clamping part 4 into the docking groove 52 of the clamp head 2, and inserting the iron insert 53 into the slot 54, where it is magnetically attracted to the permanent magnet 55, thus quickly fixing the minimally invasive clamping part 4. Then, the levers 565 are released, and under the rebound force of the first spring 564, the clamping part 4 is pushed... The moving locking rod 568 moves into the locking hole 569 to lock, thus ensuring the stability of the connection and the accuracy of the detection. When disassembling, simply push the levers 565 to both sides, so that the two levers 565 move to both sides along the through groove 562 to squeeze the first spring 564, thereby driving the two locking rods 568 fixed on the connecting plate 567 to move to both sides and disengage from the locking hole 569. Pull out the micro-invasive clamping part 4, so that the docking block 51 disengages from the docking groove 52, and the micro-invasive clamping part 4 can be pulled out from the clamping head 2. The operation is convenient, greatly improving the operation efficiency and facilitating the maintenance and replacement of the micro-invasive clamping part 4.

[0028] Furthermore, the inner side of the minimally invasive clamping part 4 is provided with anti-slip texture 11. The minimally invasive clamping part 4 is made of medical-grade stainless steel, and its end is arc-shaped. The curvature of the arc is adapted to the shape of the tooth to better fit the tooth, improve the stability of clamping, and reduce damage to the gums. For different teeth, various sizes of minimally invasive clamping parts 4 can be equipped, such as small arc-shaped clamping parts for deciduous teeth, medium-sized arc-shaped clamping parts for permanent teeth, and special-angle arc-shaped clamping parts for wisdom teeth. Doctors can choose flexibly according to actual needs. The anti-slip texture 11 consists of staggered convex strips with a height of 0.1-0.3mm. This provides a good anti-slip effect without causing excessive wear on the tooth surface. The anti-slip texture 11 is staggered in a horizontal and vertical manner. On the inner surface of the minimally invasive clamping part 4 that contacts the tooth, some convex strips are arranged in the horizontal direction, and other convex strips are arranged vertically perpendicular to the horizontal convex strips to form a grid structure, which enhances multi-directional friction.

[0029] The working principle of this invention is as follows: Before tooth extraction, the dentist first selects a suitable minimally invasive clamping part 4 based on the type and size of the patient's teeth, such as deciduous teeth, permanent teeth, and wisdom teeth. Using the quick-release mechanism 5, the prying blocks 565 are first opened to both sides, causing the two locking rods 568 to move outwards relative to each other. The connecting block 51 of the minimally invasive clamping part 4 is inserted into the connecting groove 52 of the forceps head 2, and the iron insert 53 is inserted into the slot 54, magnetically attracting the permanent magnet 55, thus quickly fixing the minimally invasive clamping part 4. Releasing the prying blocks 565, under the rebound force of the first spring 564, pushes the locking rods 568 to move towards the center and insert them into the locking hole 569, completing the fixation. At this time, the conductive contacts on the contact surfaces of the connecting block 51 and the connecting groove 52 come into contact with each other. To ensure effective electrical connection between the pressure sensor 12, temperature sensor 13, and the minimally invasive clamping part 4, the battery cover 8 on the forceps handle 1 is opened and the battery 9 is inserted to power the electronic components. Then, the doctor adjusts the initial distance between the two forceps handles 1 by rotating the adjusting nut 63, so that the minimally invasive clamping part 4 of the forceps head 2 obtains a suitable initial opening degree, so as to accurately align with the target tooth. The doctor holds the forceps handle 1 and inserts the minimally invasive clamping part 4 into the patient's oral cavity. Using the 120-150 degree bending angle between the minimally invasive clamping part 4 and the forceps handle 1, the position is flexibly adjusted in the narrow space of the oral cavity, so that the inner concave surface of the arc-shaped minimally invasive clamping part 4 fits against the tooth surface. At this time, the inner mesh-like anti-slip texture 11 contacts the tooth, enhancing friction and preventing slippage. During operation, the doctor presses the control button to activate the pressure sensor 12 and temperature sensor 13. When the doctor presses the forceps handle 1, the two forceps rotate around the connecting shaft 3, causing the minimally invasive clamping part 4 to close and clamp the teeth. The adjusting screw 61 slides within the through hole 62 as the forceps handle 1 moves, and the second spring 10 is compressed. During this process, the pressure sensor 12 detects the pressure between the two minimally invasive clamping parts 4 and the teeth in real time by sensing the slight deformation of the forceps head 2 caused by clamping, and transmits the data to the display screen 7. The display screen 7 detects the temperature of the contact area by sensing the temperature change transmitted by the forceps head 2 and displays it on the display screen 7. By observing the display screen 7, the doctor adjusts the clamping force according to the pressure value to avoid excessive pressure that could damage the tissue. At the same time, the doctor pays attention to the temperature value. If the temperature is too high, such as due to inflammation or friction, the doctor takes immediate measures such as pausing the operation or adjusting the clamping method to prevent tissue burns. Once the tooth is successfully extracted, the dentist releases the forceps handle 1. The second spring 10, relying on its own elastic force, pushes the two forceps handles 1 to move in opposite directions, causing the forceps head 2 and the minimally invasive clamping part 4 to open automatically, completing one tooth extraction operation. If multiple teeth of different types need to be processed continuously, the corresponding minimally invasive clamping part 4 can be replaced, and the above operation process can be repeated.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's technology and inventive concept of a minimally invasive painless tooth extraction forceps, should be covered within the scope of protection of the present invention.
