Description

Technical Field

[0001] This utility model belongs to the field of oral medicine, specifically relating to an occlusal clamping tool. Background Technology

[0002] In dentistry, traditional occlusal forceps are commonly used to examine a patient's bite by holding an occlusal paper. These forceps are mostly made of stainless steel, have a simple structure, and resemble ordinary surgical forceps in appearance, except that their ends have a special gripping structure to prevent the occlusal paper from slipping. These tools are durable, easy to sterilize, and inexpensive. However, when using these occlusal forceps, only one occlusal paper can be held at a time, and they can usually only be used to examine one side of the dental arch. If a full mouth examination is required, the forceps need to be changed multiple times, which is not only cumbersome, but also may lead to inconsistent examination results due to slight changes in the patient's jaw position. If two occlusal forceps are used at the same time, the ends of the forceps may cross and collide, affecting the operator's examination.

[0003] In addition, occlusal elevation is a common treatment technique in clinical practice, and it is usually performed using the following methods: 1) Use materials such as wax sheets or occlusal recording silicone to place between the occlusal surfaces of the patient's upper and lower dentitions, instruct the patient to slowly bite down to a certain height, and remove the material after it has completely solidified, thereby obtaining an occlusal record that elevates the expected thickness of the bite. 2) Place a certain thickness of soft elastic material in the anterior or posterior tooth area of ​​the patient, instruct the patient to bite normally, and directly use an intraoral optical scanner to scan and obtain the occlusal relationship; or build up occlusal recording silicone on the occlusal surfaces of other teeth except where the soft elastic material is placed, and instruct the patient to bite slowly. Remove the occlusal recording silicone after it has completely solidified, thereby obtaining an occlusal record with the expected thickness of the occlusion.

[0004] The above method 1 has the following drawbacks when implemented: the thickness of the material after occlusion often cannot reach the expected level, requiring repeated occlusion, which requires a high level of experience from both the patient and the physician, and the wax sheet cannot be well preserved. The above-mentioned method 2 has the following drawbacks when implemented: When placing soft elastic material in the anterior tooth area of ​​the patient, it is easy to cause the patient's mandible to retract, resulting in a large error in the obtained occlusal record, which ultimately affects the occlusal accuracy; When placing soft elastic material in the posterior tooth area of ​​the patient, the conventional operation involves manual placement or the use of traditional occlusal paper forceps. The patient's tongue can easily push the soft elastic material out of the correct position on the occlusal surface. Some patients with limited mouth opening cannot successfully place the material on the occlusal surface of the last teeth, and it is impossible to use instruments to place the material at the same time.

[0005] Therefore, there is an urgent need for a new biting clamping tool to solve the problems existing in the current technology. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a biting clamping tool. The present invention provides a biting clamping tool, including a set of symmetrically arranged biting clamps and a handle for easy pressing and holding of the biting clamps. The biting clamps include a clamping part for clamping medical materials and a locking part for providing clamping force. The clamping part is an arc-shaped structure for easy adaptation to the dental arch. The locking part is hinged to the handle to adjust the opening between the biting clamps.

[0007] Furthermore, the bite clamp includes two thin metal sheets, one end of which is bent to form a clamping part, and the other end is welded to form a locking part; the handle includes two clamping pieces with the same structure, which are located on the upper and lower sides of the bite clamp.

[0008] Specifically, each clamping piece has a first through hole on the side near the clamping part, and a first pin is provided through the two first through holes to limit the clamping pieces from opening too much and to prevent the clamping pieces from gathering too much.

[0009] Specifically, each locking part is provided with a second through hole, and each clamping piece is provided with two symmetrical third through holes on the side away from the clamping part, which are adapted to the second through holes. A second pin is provided through the third through holes and the second through holes on the two clamping pieces.

[0010] Furthermore, each bite clamp has a locking part and an opening limit structure located outside the hinge point to limit excessive outward rotation of the bite clamp.

[0011] Specifically, the opening limit structure is ridge-shaped, and the ridge-shaped structure is integrally formed with the occlusal clamp.

[0012] Furthermore, the clamping surface is provided with a first anti-slip texture to increase friction when clamping medical materials. The first anti-slip texture may be circular, toothed, striped, or diamond-shaped.

[0013] Furthermore, the surface of the handle is provided with a second anti-slip texture in the shape of a "well" for easy gripping.

[0014] Furthermore, the medical materials include one of the following: biting paper, biting wax sheet, and soft elastic pad.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: 1) By setting a set of symmetrical occlusal clips, this utility model can simultaneously clamp various sizes of occlusal paper and soft elastic materials commonly used in clinical practice, and can also examine or elevate the occlusion of bilateral posterior teeth or all teeth. 2) This utility model hinges the locking part of the bite clamp to the handle via a pin, which enables the opening of the bite clamp to be adjusted to accommodate the dental arch size of different patients; 3) The present invention has an opening limit structure in the locking part of the bite clamp and outside the hinge point, which can control the bite clamp from opening too far outward. 4) This utility model connects the bite clamp with a special structure at the tail and the handle by a pin, which enables the simultaneous and rapid placement of medical materials on both sides of the patient's posterior teeth area, and the material can be quickly and easily removed after the patient bites down.

[0016] 5) The present invention provides a first anti-slip texture in the bite surface of the bite clamp in the form of a circle, tooth, strip or rhombus, which can prevent the medical materials held by the clamp from falling during operation; and provides a second anti-slip texture in the form of a "well" on the surface of the handle, which can enhance the stability of the operator's grip.

[0017] In summary, the occlusal clamping tool proposed in this utility model provides convenience for dentists during the operation process, saves examination time, and ensures the quality of treatment for patients and the accuracy of related occlusal materials. Attached Figure Description

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example

[0024] See Figure 1 The present invention provides a biting clamping tool, including a set of symmetrically arranged biting clamps 1 and a handle for easy pressing and holding of the biting clamps 1. The biting clamps 1 include a clamping part for clamping medical materials and a locking part for providing clamping force. The clamping part is an arc-shaped structure for easy adaptation to the dental arch. The locking part is hinged to the handle to adjust the opening between the biting clamps 1.

[0025] The clamping clip 1 includes two thin metal sheets, one end of which is bent to form a clamping part, and the other end is welded to form a locking part; as shown Figure 1 As shown, the handle includes two clamping pieces 2 with the same structure and disposed on the upper and lower sides of the biting clamp 1; each clamping piece 2 has a first through hole 3 on the side near the clamping part, and a first pin is disposed through the two first through holes 3 to limit the clamping pieces 2 from opening too much and prevent the biting clamp 1 from closing too much.

[0026] See Figure 2 Each locking part is provided with a second through hole, and each clamping piece 2 is provided with two symmetrical third through holes 4 on the side away from the clamping part, which are adapted to the second through holes. The third through holes 4 on the two clamping pieces 2 and the second through holes are provided with second pins.

[0027] See Figure 3 Each bite clamp 1 has a locking part and a ridge-shaped opening limit structure located outside the hinge point to limit the excessive outward rotation of the bite clamp 1. The ridge-shaped opening limit structure is integrally formed with the bite clamp 1.

[0028] Specifically, the biting surface of the clamping part is provided with a first anti-slip texture to increase friction when clamping medical materials. The first anti-slip texture includes a circle, tooth, strip, or rhombus shape, and the surface of the handle is provided with a second anti-slip texture to facilitate gripping.

[0029] In this embodiment, when using the occlusal elevation treatment method, taking a soft elastic pad as an example: First, the opening of the occlusal clip 1 is manually adjusted to suit the dental arch size of different patients. Then, the clip 2 is pressed simultaneously to open the clamping part of the occlusal clip 1, and the soft elastic pad is placed within the occlusal surface of the arc-shaped structure (e.g., Figure 4 (As shown), then release clip 2 and insert occlusal clip 1 into the patient's mouth between the upper and lower jaws (as shown). Figure 5 As shown), after the patient bites down firmly on the soft elastic pad, immediately press clip 2 to remove the occlusal clamping tool, leaving only the soft elastic pad between the posterior teeth. This allows for stable and quantitative elevation of the posterior tooth occlusion, facilitating the next step of digital occlusal relationship acquisition. When performing an occlusal examination on a patient, using occlusal paper as an example: First, manually adjust the opening of occlusal clamp 1 to suit different patients' dental arch sizes. Then, press clip 2 to open the clamping part of occlusal clamp 1, placing the occlusal paper within the occlusal surface of the arc-shaped structure. Subsequently, release clip 2 and insert occlusal clamp 1 into the patient's mouth between the upper and lower jaws (e.g., Figure 6 (As shown).

[0030] It should be noted that the main body of the first pin is a smooth cylinder with a diameter matching the first through hole 3. Limiting protrusions are fixed on the outer periphery of both ends of the first pin to limit the separation of the two clamping pieces 2 in the direction perpendicular to the pin axis. The first pin passes through the first through hole 3 between the two clamping pieces 2 to prevent the biting clamp 1 from excessively closing. The second pin passes through the second through hole of the locking part of the biting clamp 1 and the third through hole 4 on the clamping piece 2, so that the biting clamp 1 can rotate flexibly around the axis of the second pin. A ridge-shaped opening limit structure is also provided in the locking part of the biting clamp 1 to limit the biting clamp 1 from rotating excessively outward.

[0031] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0032] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
