Description

Technical Field

[0001] This utility model relates to the field of bone biting forceps, and in particular to a bone biting forceps with anti-slip properties on the bone surface and the function of removing bone fragments. Background Technology

[0002] The alveolar bone, also known as the alveolar process, is the protruding part of the jawbone surrounding the tooth root. The alveolar bone has inner and outer plates composed of compact bone, with cancellous bone sandwiched between them. However, the palatal plate on the medial side of the maxilla is thicker than the buccal plate on the lateral side and has many small openings leading to the cancellous bone. Tooth loss easily leads to irregular alveolar bone morphology. Furthermore, the post-operative tissue repair and remodeling process can cause an imbalance between alveolar bone resorption and regeneration, with some areas remodeling faster than others, resulting in sharp bony cusps and ridges in certain areas. In addition, improper force direction and magnitude during tooth extraction often lead to alveolar bone fractures and displacement. If the damaged and displaced alveolar bone is not promptly repositioned, it can also result in sharp bony cusps, ridges, protrusions, and undercuts. Therefore, it is necessary to promptly use bone forceps to trim and remove the alveolar bone.

[0003] However, during the removal of alveolar bone, the sharp metal beaks of the bone forceps are prone to slipping after contacting the irregular and hard, bloody cortical bone wall, making it impossible to remove the bone in the desired shape. In addition, the cortical bone is hard and requires a great deal of biting force, so bone fragments often fly around in the mouth at the moment of biting down, which is detrimental to surgical safety, easily causes contamination, and most importantly, the bitten bone fragments lose the opportunity to be reused, resulting in the waste of high-quality bone tissue. Utility Model Content

[0004] To address the technical problems in existing technologies where bone forceps easily slip during alveolar bone trimming, resulting in unsatisfactory alveolar bone morphology, and bone fragments are easily scattered by the forceps, causing the bitten bone fragments to lose the opportunity for reuse and resulting in the waste of high-quality bone tissue, this utility model provides the following technical solution.

[0005] This utility model discloses a bone-biting forceps with a bone-slip surface and bone-removing function, comprising a first handle connected to a first jaw and a second handle connected to a second jaw with a second jaw hinged to the first handle. The first jaw and the second jaw are respectively fixedly connected to a first positioning member and a second positioning member with the same structure and arranged opposite to each other. The first positioning member and the second positioning member are respectively connected to a first cutting blade and a second cutting blade arranged opposite to each other. A bone storage cavity is formed between the first jaw and the second jaw. Flexible baffles connected to the first jaw and the second jaw are provided on both sides of the bone storage cavity. The front side of the bone storage cavity is closed by the first cutting blade and the second cutting blade.

[0006] As a further technical solution, the first positioning member includes a housing with a movable cavity fixedly connected to the first clamping edge and a telescopic sleeve with a spring connected to its outer periphery fixedly connected to the bottom of the movable cavity. The telescopic sleeve extends out of the movable cavity and is fixedly connected to an anti-slip clamp.

[0007] As a further technical solution, the movable part of the telescopic sleeve located in the movable cavity is fixedly provided with a fixing ring, and the fixing ring is connected to the spring.

[0008] As a further technical solution, the anti-slip chuck is provided with a number of anti-slip components on its outer circumference in both the axial and radial directions.

[0009] As a further technical solution, the anti-slip component is a hemispherical protrusion, a sharp protrusion, or a frosted surface.

[0010] As a further technical solution, the portions of the first and second clamp edges located on opposite sides within the bone storage cavity are each provided with several indwelling plates.

[0011] As a further technical solution, the flexible baffle is made of an elastic material.

[0012] The beneficial effects of this utility model are as follows: the first and second jaws of this utility model are respectively connected to a first positioning element and a second positioning element. The first and second positioning elements can elastically clamp onto the alveolar bone surface, which helps to position the bone biting forceps before contacting the bone and prevents slippage during the biting process, ensuring the stability of the bone biting forceps during the biting process and ensuring successful bone biting. A bone storage cavity is provided on one side of the first and second cutting blades. During the biting process, both the first and second cutting blades move towards the bone storage cavity to bite the bone, allowing the bitten bone fragments to enter the bone storage cavity. This prevents bone fragments from flying everywhere, and the bone fragments in the bone storage cavity can be reused, ensuring the effective utilization of high-quality bone.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0018] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] like Figure 1 As shown, the present invention provides a bone-biting forceps with a bone-slip surface and bone-removing function, comprising a first handle 1 connected to a first clamping edge 3 and a second handle 2 connected to the first handle 1 with a second clamping edge 4. When medical personnel hold the first handle 1 and the second handle 2, the first clamping edge 3 and the second clamping edge 4 are relatively close or relatively far apart. It adopts an existing structure, which will not be described in detail here.

[0020] In a preferred embodiment, the first jaw 3 and the second jaw 4 are respectively fixedly connected to a first positioning member 5 and a second positioning member 6 with identical structures and arranged opposite to each other. The first positioning member 5 and the second positioning member 6 can be elastically clamped on the alveolar bone surface to assist in the positioning of the bone-biting forceps before contacting the bone and to prevent slippage during bone biting, thus ensuring the stability of the bone-biting forceps during bone biting. The first positioning member 5 and the second positioning member 6 are respectively connected to a first cutting blade 7 and a second cutting blade 8 arranged opposite to each other. When the first jaw 3 and the second jaw 4 are relatively close, the first positioning member 5 and the second positioning member 6 clamp the alveolar bone, while the first cutting blade 7 and the second cutting blade 8 deflect towards each other and remove and trim excess alveolar bone.

[0021] like Figure 3 As shown, in a preferred embodiment, since the first positioning member 5 and the second positioning member 6 have the same structure, only the first positioning member 5 will be described in detail below. The first positioning member 5 includes a housing 501 fixedly connected to the first clamping edge 3. The housing 501 has a movable cavity 502 inside. A telescopic sleeve 503 is fixedly connected to the bottom of the movable cavity 502. A spring 504 is connected to the outer periphery of the portion of the telescopic sleeve 503 located inside the movable cavity 502. An anti-slip clamp 506 is fixedly connected to the portion of the telescopic sleeve 503 extending out of the movable cavity 502. At this time, a fixing ring 505 is fixedly provided on the movable part of the telescopic sleeve 503 located inside the movable cavity 502. The fixing ring 505 is connected to the spring 504.

[0022] When the first jaw 3 and the second jaw 4 engage with each other, the first positioning member 5 and the second positioning member 6 clamp the alveolar bone. Under the elastic force of the spring 504, the anti-slip chuck 506 clamps the alveolar bone. As the first cutter 7 and the second cutter 8 cut the upper end of the alveolar bone, the anti-slip chuck 506 retracts, the movable end of the telescopic sleeve 503 retracts, and the spring 504 retracts. Under the elastic force of the spring 504, the anti-slip chuck 506 has a greater clamping force on the alveolar bone, ensuring that it does not slip during the bone biting process.

[0023] In a preferred embodiment, the anti-slip chuck 506 is provided with a plurality of anti-slip elements 507 on its outer circumference in the axial and radial directions. The anti-slip elements 507 can be hemispherical protrusions as shown in the figure, or they can be sharp protrusions or frosted surfaces, etc., to prevent the bone surface from slipping.

[0024] like Figure 2 As shown, in a preferred embodiment, a bone storage cavity 10 is formed between the first clamping edge 3 and the second clamping edge 4. Flexible baffles 9, connected to the first clamping edge 3 and the second clamping edge 4, are provided on both sides of the bone storage cavity 10. Both flexible baffles 9 are made of elastic material and are connected to the first clamping edge 3 and the second clamping edge 4 on three sides. When the first clamping edge 3 and the second clamping edge 4 open or close, the flexible baffles 9 can freely and elastically extend to ensure the sealing of the bone storage cavity 10. Thus, the two flexible baffles 9, the first clamping edge 3, and the second clamping edge 4 are connected to form the bone storage cavity 10. At this time, the bone storage cavity 10 has only one opening, with a first cutter 7 and a second cutter 8 on its front side; that is, the front side of the bone storage cavity 10 is closed by the first cutter 7 and the second cutter 8. When the first cutting blade 7 and the second cutting blade 8 are close together to bite and trim the alveolar bone, the first cutting blade 7 and the second cutting blade 8 rotate towards the bone storage cavity 10 while biting the bone. This allows the bitten bone fragments to enter the bone storage cavity 10 and remain there, preventing bone fragments from flying. At the same time, the bone fragments in the bone storage cavity 10 can be removed and reused, ensuring the effective utilization of high-quality bone.

[0025] In a preferred embodiment, the portion of the first clamping edge 3 and the second clamping edge 4 located in the bone storage cavity 10 on opposite sides is provided with a plurality of retention plates 11. The retention plates 11 can be the inclined plate structure shown in the figure, or other inclined structures that can retain bone fragments. This utility model does not make any particular limitation on them. After the bone is bitten, the first clamping edge 3 and the second clamping edge 4 are opened, and the bone fragments can be taken out from the openings of the first cutter 7 and the second cutter 8.

[0026] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
