Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a multifunctional sleeve crown removal device. Background Technology

[0002] Telescopic crowns have a long history of clinical application in dentistry. Their retainers consist of an inner crown and an outer crown. The inner crown is cemented to the abutment tooth, and the outer crown is fitted over the inner crown. The precise interlocking between the two creates strong retention, providing stable support for removable dentures. During dental restoration procedures, whether technicians are performing clinical work or fabricating the crown, they often need to remove the metal inner crown of the telescopic crown retainer from the tissue surface of the outer crown.

[0003] Because the inner and outer crowns are precisely fitted together, disassembly is difficult. Therefore, a special sleeve crown removal device is required. Most existing sleeve crown removal pliers adopt a traditional pliers structure design, which has many defects in actual use.

[0004] Firstly, some crown retrieval forceps use a slow rotation of a turntable in the middle to move the two forceps away from each other, creating a clamping force on the inner crown and facilitating its removal from the outer crown tissue. However, this slow rotation is inconvenient to use. Secondly, it is difficult for the user to apply force. The traditional design makes it difficult to control the direction of force during crown retrieval, hindering the effective transfer of force to the inner crown and making the process very strenuous. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional sleeve crown removal device that can quickly and easily lock and fix the metal inner crown during use, facilitating rapid removal. It is also equipped with a first grip and a second grip for easy gripping and control of force by the operator.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A multifunctional sleeve crown removal device includes a first grip C, a second grip C, a first assembly plate, and a second assembly plate;

[0008] One end of the first grip C is fixedly connected to the left side of the periphery of the first assembly plate, and one end of the second grip C is fixedly connected to the right side of the periphery of the second assembly plate.

[0009] The first clamping components are fixedly installed on both the left and right sides of the periphery of the first assembly plate.

[0010] The second clamping components are fixedly installed on both the left and right sides of the periphery of the second assembly plate.

[0011] The first grip C and the second grip C are fixed together on one side of each other with a spring.

[0012] As a preferred technical solution, both the first grip C and the second grip C are provided with anti-slip grip sleeves on their lower periphery.

[0013] As a preferred technical solution, assembly rings are fixedly installed on the middle of the side of the first gripping C and the second gripping C, and connecting shafts are rotatably assembled inside the two assembly rings. The two ends of the spring are fixedly connected to the periphery of the two connecting shafts respectively.

[0014] As a preferred technical solution, the first clamping component includes a first clamp C, one end of which is fixedly connected to the periphery of the first assembly plate, and an extension block is fixedly installed on the end of the first clamp C away from the first assembly plate.

Detailed Implementation

[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-2 As shown, the present invention provides a multifunctional sleeve crown removal device, including a first grip C1, a second grip C2, a first assembly plate 3 and a second assembly plate 4; both the first grip C1 and the second grip C2 are provided with anti-slip grip sleeves 7 on their lower periphery.

[0030] The staff held two non-slip grip sleeves, which made the grip more comfortable and provided better anti-slip effect.

[0031] One end of the first grip C1 is fixedly connected to the left side of the periphery of the first assembly plate 3, and one end of the second grip C2 is fixedly connected to the right side of the periphery of the second assembly plate 4. The first assembly plate 3 and the second assembly plate 4 are distributed in front and behind each other, and the first assembly plate 3 and the second assembly plate 4 are rotatably connected by a rotating shaft 5.

[0032] The first clamping component 31 is fixedly installed on both the left and right sides of the first assembly plate 3.

[0033] The second clamping assembly 41 is fixedly installed on both the left and right sides of the second assembly plate.

[0034] The first grip C1 and the second grip C2 are fixedly mounted together on one side of each other with a spring 6.

[0035] In the initial state, due to the setting of spring 6, the first grip C1 and the second grip C2 are in an open state. Therefore, the first clamping component 31 and the second clamping component 41 on the left are close to each other, while the first clamping component 31 and the second clamping component 41 on the right are far apart. When the operator grips the first grip C1 and the second grip C2, the first clamping component 31 and the second clamping component 41 on the left are far apart, while the first clamping component 31 and the second clamping component 41 on the other side are close together. This forms two clamping parts, one side for opening and the other side for clamping. The clamping part can be used to clamp the crown for grinding, and the opening part can extend into the inner crown to apply an opening clamping force, making it easier to remove the metal inner crown. Both the first grip C1 and the second grip C2 adopt an extended C structure, which makes it easier for the operator to apply force and control the direction of force, so as to quickly remove the metal inner crown, making it more convenient and faster to use.

[0036] The first grip C1 and the second grip C2 are both fixedly installed with assembly rings 8 at the middle of their respective sides. The two assembly rings 8 are rotatably fitted with connecting shafts 81. The two ends of the spring 6 are fixedly connected to the periphery of the two connecting shafts 81 respectively. The elastic force generated by the spring 6 is applied to the two connecting shafts 81, which can make the first grip C1 and the second grip C2 move away from each other and use the pushing force of the spring 6 to perform the reset operation.

[0037] The first clamping assembly 31 includes a first clamp 311, one end of which is fixedly connected to the periphery of the first assembly plate 3, and an extension block 312 is fixedly installed on the end of the first clamp 311 away from the first assembly plate 3. A first grinding needle 313 is detachably installed on the side of the extension block 312 away from the first assembly plate 3.

[0038] The second clamping assembly 41 includes a second clamp 411, one end of which is fixedly connected to the periphery of the second assembly plate 4, and a second grinding needle 412 is detachably installed at the end of the second clamp 411 away from the second assembly plate 4.

[0039] When using, such as Figure 1As shown, in the initial state, the first grinding needle 313 and the second grinding needle 412 of appropriate size are selected for installation. During installation, the existing design of the snap-fit ​​structure or the threaded connection structure can be used for installation and fixation. After installation, the first grinding needle 313 and the second grinding needle 412 on the left can be inserted into the metal inner crown. When the operator controls the first grip C1 and the second grip C2 to move closer to each other, a spreading force can be generated to facilitate snap-fit ​​with the inside of the metal inner crown, and then force is applied to pull them out. On the other side, the first grinding needle 313 and the second grinding needle 412 are close to each other and far apart from each other, which can be used to hold the crown for grinding and other operations, further increasing functionality and practicality.

[0040] Both the first grinding needles 313 and the second grinding needle 412 are provided with anti-slip layers around their peripheries, and both the first grinding needles 313 and the second grinding needle 412 are provided with positioning protrusions 413 around their peripheries. During use, the anti-slip layers can increase the contact friction, while the positioning protrusions 413 will attempt to embed into the pre-set grooves or small holes on the inner crown tissue surface to achieve initial positioning. The technician can further determine the accurate position of the bur by adjusting the forceps handle according to the actual situation of the inner crown, so that the fitting and removal part can fully contact and align with the inner crown tissue surface, making it easier to use. In addition, the positioning protrusions 413 can effectively hold the inner crown, ensuring that there will be no slippage during the crown removal process.

[0041] Both the first grinding needle 313 and the second grinding needle 412 are made of ceramic or stainless steel. This material has high hardness and wear resistance, and can be accurately embedded in the grooves or holes of the inner coronary tissue surface to provide a stable positioning effect.

[0042] The device is used as follows:

[0043] In the initial state, the spring 6 causes the first gripping component 1 and the second gripping component 2 to be in an open state. At this time, the first clamping component 31 and the second clamping component 41 on the left side are close to each other, while the right side is far away from each other. First, select the first grinding needle 313 and the second grinding needle 412 of appropriate size according to actual needs. Using existing structures such as snap-fit ​​or threaded connection, install the first grinding needle 313 on the extension block 312 of the first clamping component 311 and install the second grinding needle 412 on the second clamping component 411.

[0044] If crown removal is required, the operator holds the non-slip grip sleeve 7 on the lower side of the first grip C1 and the second grip C2, and inserts the first grinding needle 313 and the second grinding needle 412, which are close to each other on the left, into the metal inner crown. At this time, the positioning protrusion 413 on the periphery of the first grinding needle 313 and the second grinding needle 412 will be embedded into the pre-set groove or small hole on the tissue surface of the inner crown to achieve initial positioning. Then, force is applied to bring the first grip C1 and the second grip C2 closer to each other, and the first clamping component 31 and the second clamping component 41 on the left will move away from each other, generating a spreading force and clamping the inner crown. The operator controls the direction of force by extending the grip C, and applies force to pull out the metal inner crown, completing the crown removal.

[0045] If crown polishing is required, the worker continues to hold the anti-slip grip 7. When the first grip C1 and the second grip C2 are close to each other, the first polishing needle 313 and the second polishing needle 412 on the right side, which are far apart, clamp the crown to be polished. During the polishing process, the anti-slip layer around the first polishing needle 313 and the second polishing needle 412 can increase the contact friction and prevent the crown from slipping. The worker adjusts the force and angle as needed to complete the polishing operation.

[0046] After the operation is completed, the force applied to the grip C is released. The spring 6, through the connecting shaft 81 connected at both ends, is assembled in the assembly ring 8 and generates a thrust, so that the first grip C1 and the second grip C2 return to the open state for easy use next time.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
