Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a dental extraction forceps with depth limiting baffle. BACKGROUND

[0002] Extraction is a common operation in clinical practice, especially in intentional tooth replantation and orthodontic tooth extraction, which requires maximum protection of the alveolar bone and root surface cementum to ensure postoperative healing and successful reattachment and reduce postoperative complications. Most of the clinical commonly used extraction forceps (such as dental extraction forceps, root tip forceps, etc.) in the prior art are usually composed of beak, joint and handle, and the core of its structure is the stability of clamping and the leverage of labor saving, which focuses on clamping force and extraction efficiency. The beak often lacks precise control of the insertion depth, which makes the depth rely on the doctor's experience during operation, that is, the doctor controls the depth by hand feeling, which is easy to cause insertion too deep or position deviation, and it is difficult to control the depth in the actual operation process because the beak is in a converging state, which may lead to alveolar bone wall fracture, especially the thinner bone wall on the buccal and lingual sides, which may cause small bone fragments to be detached with the tooth or residual bone wall defect, and may also cause alveolar bone loss, which may damage the normal shape and height of the alveolar bone, affecting subsequent orthodontic, implantation and other treatments; it may also scrape or wear the cementum on the surface of the tooth root, exposing the underlying dentin, which may cause tooth sensitivity and pain when exposed to cold or hot stimuli after operation; increase the risk of intraoperative trauma or postoperative complications. Moreover, the extraction forceps in the prior art cannot better act on the treatment operation of the replanted tooth or orthodontic tooth, resulting in poor universality. SUMMARY

[0003] The purpose of the present application is to provide a dental extraction forceps with depth limiting baffle, which solves the problem of poor universality and inability to effectively control the insertion depth of the beak in the prior art.

[0004] The technical scheme of the present application is as follows:

[0005] The present application provides a dental extraction forceps with depth limiting baffle, which comprises a working assembly and a depth control assembly, two working assemblies are connected by rotating joints, and the depth control assembly is connected to the rotating joint; the depth control assembly comprises at least an adjusting knob and a limiting baffle connected to the adjusting knob, the rotation of the adjusting knob adjusts the height of the limiting baffle, and the adjusting knob is connected to one side of the rotating joint.

[0006] Further, the working assembly comprises a beak and a handle connected thereto, and the adjusting knob and the limiting baffle are located between the two handles.

[0007] Furthermore, an adjusting gear is connected to one end of the limiting baffle near the rotating joint, and the adjusting gear is movably connected to the adjusting knob.

[0008] Furthermore, the rotating joint is connected to a limiting ear on its side, and the adjusting gear is connected between the two limiting ears.

[0009] Furthermore, the depth control assembly also includes a rotating worm gear, the top of which is connected to the adjustment knob and the bottom of which is connected to the positioning plate.

[0010] Furthermore, a limiting rod is connected between the two limiting ears, and the limiting rod passes through the adjusting gear.

[0011] Furthermore, a control groove is provided between the two limiting ears, and part of the adjusting gear extends into the control groove and meshes with the rotating worm gear.

[0012] Furthermore, the adjustment knob has scale markings.

[0013] Furthermore, the outer circumference of the adjustment knob has an anti-slip strip.

[0014] Furthermore, the limiting baffle is arc-shaped.

[0015] Based on the above technical features, the beneficial effects of this invention are as follows: This invention provides a dental extraction forceps with a depth limiting baffle. Through the designed depth control component, the forceps can rigidly limit the insertion depth of the forceps beaks during use, avoiding alveolar bone damage and cementum scratching of the tooth root surface due to excessive depth. The height adjustment function of the limiting baffle can adapt to the needs of special clinical scenarios such as intended tooth replantation, autologous tooth transplantation, and orthodontic tooth extraction, meeting different depth control requirements. The gear transmission structure of the rotating worm and the adjusting gear enables high-precision control of the limiting baffle height adjustment; the axial limiting effect of the limiting rod on the adjusting gear effectively prevents potential gear shifting during transmission, improving the overall reliability and durability of the structure. The arc-shaped structure of the limiting baffle combined with the scale markings on the adjusting knob enhances the safety and accuracy of the operation, reducing the risk of operational errors and complications caused by inexperienced dentists. This invention solves the technical problem that existing tooth extraction forceps cannot control the insertion depth of the forceps beak. It not only enables precise control of the insertion depth of the forceps beak, but also reduces the reliance on the doctor's experience in an intuitive way, thereby improving the safety and standardization of the tooth extraction process.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0021] It should be noted that the prior art includes patents titled "A Special Tooth Forceps for Intended Replantation" (publication number CN214180634U) and "A Multifunctional Tooth Extraction Forceps" (publication number CN117159185A), but none of these technologies can achieve the limitation on the placement depth of the tooth extraction forceps.

[0022] Example

[0023] Please refer to the above as well. Figs. 1-3 An embodiment of the present invention provides a dental extraction forceps with a depth limiting baffle 5. The device includes a working component and a depth control component. The two working components are crossed and rotatably connected to form a rotating joint 3. The rotating joint 3 is connected to the depth control component. The depth control component includes at least an adjustment knob 4 and a limiting baffle 5 connected to the adjustment knob 4. The rotation of the adjustment knob 4 realizes the adjustment of the height of the limiting baffle 5. The adjustment knob 4 is connected to one side of the rotating joint 3.

[0024] It is worth noting that most existing extraction forceps only involve the beak 1 and handle 2, without any physical limiting structure. During use, the beak 1 can be inserted into the alveolar socket without restriction, and the depth depends entirely on the doctor's feel. This can easily lead to alveolar bone damage and cementum scratches on the root surface due to excessive depth. Moreover, the existing technology cannot meet the special needs of intended tooth replantation, autologous tooth transplantation, and orthodontic tooth extraction. In addition, novice doctors are prone to complications due to misjudging the depth. This invention provides an extraction forceps with a depth limiting baffle 5. The two working components are hinged together by a rotating joint 3 to ensure that the beak 1 can open and close flexibly to grasp the tooth. The depth control component is connected to the rotating joint 3 to achieve precise control of the extraction depth. Specifically, the limiting baffle 5 abuts against the crown of the tooth, physically limiting the insertion depth of the beak 1 and preventing excessive depth damage to the alveolar bone or cementum. The baffle also serves as a visual depth reference, reducing reliance on the doctor's experience and improving safety.

[0025] In detail, the working components include a jaw 1 and a handle 2. The jaw 1 and handle 2 are rigidly connected to form an integral structure. The end of the jaw 1 has an arc-shaped design to adapt to the shape of the tooth crown and avoid crown breakage due to point contact. The handle 2 provides operating leverage. The two sets of working components are arranged crosswise and hinged together by a rotating joint 3. The rotating joint 3 is located at the connection between the jaw 1 and the handle 2, providing rotational freedom for opening and closing the jaw 1, and also serving as the mounting base for the depth control component.

[0026] Furthermore, a depth control component is provided between the two handles 2. This component includes an adjustment knob 4, a limiting baffle 5, an adjustment gear 6, a rotating worm gear 8, a positioning plate 9, a limiting rod 10, and a limiting ear 7. The adjustment knob 4 is located between the handles 2. The limiting baffle 5 is connected to the adjustment gear 6 by a fixed connection. The connection between the limiting baffle 5 and the adjustment gear 6 serves as a power transmission mechanism. The rotational movement of the adjustment gear 6 is directly converted into the lifting and lowering movement of the limiting baffle 5, thereby achieving a rigid limitation on the extraction depth. Preferably, the limiting baffle 5 adopts an arc-shaped structure. Its arc-shaped contour can better fit the hand curve of medical personnel when holding or operating, effectively limiting the depth of the forceps beak 1 inserted into the alveolar socket during tooth extraction.

[0027] In detail, such as Fig. 3As shown, the top of the adjusting knob 4 is fixedly connected to the rotating worm gear 8 via a key or threaded connection, and the bottom of the rotating worm gear 8 is fixedly connected to the positioning plate 9 via bolts or welding, thus ensuring the structural stability of the entire depth control assembly. The outer circumference of the adjusting knob 4 is marked with scale markings to visually display the current height position of the limit baffle 5; furthermore, the outer circumference of the adjusting knob 4 is also equipped with anti-slip strips 12, which increase friction to facilitate manual rotation of the adjusting knob 4 by the operator. The rotational movement of the adjusting knob 4 is transmitted to the adjusting gear 6 via the rotating worm gear 8, thereby driving the limit baffle 5 to achieve height adjustment. Specifically, the rotational movement of the adjusting knob 4 is transmitted to the adjusting gear 6 via the rotating worm gear 8, forming a gear transmission pair between the rotating worm gear 8 and the adjusting gear 6, utilizing the high-precision characteristics of gear transmission to achieve precise adjustment of the height of the limit baffle 5.

[0028] Furthermore, a limiting ear 7 is fixedly connected to the side of the rotating joint 3. The fixed ear is located between the two handles 2, and an adjusting gear 6 is fixedly connected between the two limiting ears 7 by bolts or a limiting rod 10. The function of the limiting ear 7 is to support and position the adjusting gear 6, preventing it from axially shifting during transmission, thereby improving the stability of the transmission process. The limiting rod 10 passes through the center hole of the adjusting gear 6 to limit the axial movement of the adjusting gear 6, while allowing it to rotate freely around the limiting rod 10, thereby improving the reliability of the transmission. A control groove 11 is opened between the limiting ears 7. After part of the tooth surface of the adjusting gear 6 extends into the control groove 11, it meshes with the tooth surface of the rotating worm 8 to form a gear transmission pair, ensuring the stability and accuracy of the transmission process, thereby realizing the precise height adjustment function.

[0029] Optionally, the limiting baffle 5 is connected to the tooth extraction forceps body by a snap or magnetic attraction, making it easy to replace baffles of different specifications as needed.

[0030] Optionally, the limiting baffle 5 is foldable, which can be folded up before surgery and unfolded and locked as needed during surgery, making it suitable for different surgical environments.

[0031] Preferably, the jaws 1 and handle 2 are made of medical-grade stainless steel, which ensures that they have sufficient strength and corrosion resistance.

[0032] Preferably, the limiting baffle 5 can be made of plastic or metal to meet the usage requirements in different scenarios.

[0033] It should be noted that during operation, firstly, the operator determines the target depth of insertion of the forceps 1 into the alveolar socket based on the specific needs of tooth extraction. Then, by manually rotating the adjustment knob 4, the rotating worm 8 drives the adjustment gear 6 to rotate. Then, the adjustment gear 6 converts the rotational motion into the lifting motion of the limit baffle 5. Then, when the limit baffle 5 reaches the target height, the operator stops rotating the adjustment knob 4, and at this time, the height position of the limit baffle 5 is locked.

[0034] It should be noted that during some operations, rotating the adjustment knob 4 will move the limiting baffle 5 to the preset position. Then, the dental forceps are placed and force is applied along the long axis of the tooth when clamping the crown until the limiting baffle 5 contacts the crown. Then, the limiting baffle 5 physically prevents the dental forceps from being inserted further, thereby ensuring that the tip of the forceps beak 1 is in a safe position.

[0035] It should be noted that in intended tooth replantation surgery, the dentist needs to precisely control the depth of insertion of the forceps beak 1 into the alveolar socket to avoid damaging the cementum on the root surface. By adjusting the scale markings on the knob 4, the dentist can quickly set the height of the limiting baffle 5, thereby ensuring that the insertion depth of the forceps beak 1 meets the surgical requirements. On the other hand, in special clinical scenarios such as autologous tooth transplantation and orthodontic tooth extraction, this invention can also meet different depth control needs, effectively improving the safety and precision of the surgery.

[0036] In summary, this invention solves the problem of uncontrollable operating depth caused by the lack of physical limiting structure in existing extraction forceps by adding a depth control component and optimizing the connection relationship and transmission method between various components. The depth control component enables precise adjustment of the insertion depth of the forceps beak 1, adapting to the needs of special clinical scenarios such as intended tooth replantation, autologous tooth transplantation, and orthodontic tooth extraction. Specifically, the limiting baffle 5 automatically limits the depth of the forceps beak 1 into the alveolar socket during the operation, protecting the alveolar bone, reducing the risk of postoperative bone damage, maintaining the integrity of the cementum on the root surface, improving the survival rate of replanted teeth, and reducing the difficulty of operation, making the extraction process safer and more standardized. Furthermore, the arc-shaped design of the limiting baffle 5, combined with the scale markings on the adjustment knob 4, enhances the safety and accuracy of the operation, reducing the risk of operational errors and complications caused by inexperienced dentists. The gear transmission pair structure of rotating worm 8 and adjusting gear 6 enables high-precision control of the height adjustment of limit baffle 5; the axial limiting effect of limit rod 10 on adjusting gear 6 can effectively prevent the deviation problem that may occur during gear transmission, thereby improving the reliability and durability of the overall structure.
