Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a pair of tooth crown clamping forceps. Background Art
[0002] Dental tweezers are a common tool used in dental procedures for grasping, securing, and manipulating teeth during dental surgery and treatment. Existing dental tweezers typically consist of a pair of blade-shaped handles with overlapping ends. These handles are made of stainless steel and positioned at an angle to each other. The tips of the handles are typically thinner, making them suitable for delicate manipulation. To grasp, the doctor presses the two handles together.
[0003] Currently, existing dental tweezers have the following technical problems during use: During the crown installation process, doctors usually use ordinary dental tweezers to clamp the crown, which takes a long time. The doctor's hands will become sore and weak from pressing or holding the two tweezers together for a long time, resulting in the weakening of the tweezers' grip, making the clamped crown prone to slipping or even falling off the tweezers. In addition, during the crown installation process, the crown needs to be pressed downward. Due to the smooth surface of the crown, using existing dental tweezers to install the crown requires the doctor to use a lot of force to clamp the crown to prevent it from slipping, which not only further increases the doctor's hand fatigue but can also easily damage the crown surface.
[0004] In response to the above technical problems, the applicant has designed a dental crown clamping tweezers that can effectively solve the above technical problems. Utility Model Content
[0005] In view of this, the purpose of the present invention is to provide a dental crown clamping tweezers, which solves the technical problem that doctors need to hold the tweezers handle tightly during the whole process of clamping the dental crown with existing dental tweezers, which causes hand fatigue.
[0006] The utility model solves the above technical problems through the following technical means:
[0007] The present invention provides a tooth crown clamping forceps, comprising a first handle, a second handle, a first beak and a second beak, wherein the tail of the first handle and the tail of the second handle are fixedly connected in a fitting manner, and the first beak and the second beak are respectively arranged at the front end of the first handle and the front end of the second handle, and are characterized in that: the plane where the fitting surfaces of the first handle and the second handle are located is a symmetry plane, the first handle is located on the left side of the symmetry plane, and the second handle is located on the right side of the symmetry plane, the first beak and the second beak are both bent in the direction of the symmetry plane, and form an X-shaped cross structure at the symmetry plane, so that the front end of the first beak is located on the right side of the symmetry plane and the front end of the second beak is located on the left side of the symmetry plane, the first handle and the second handle have an elastic force that opens to both sides, and under the action of the elastic force, the front end of the first beak and the front end of the second beak are tightly fitted together to form a clamping force. In this embodiment, the outer sides of the first handle and the second handle are affixed with a non-slip pad with a wavy surface.
[0008] Furthermore, a clamping plate is provided above the middle of each of the first tweezers beak and the second tweezers beak. The two clamping plates extend in the direction of the symmetry plane respectively, and the positions of the two clamping plates are staggered with each other.
[0009] Furthermore, a waist-shaped hole is provided in the middle of the first tweezers handle or the second tweezers handle and along the length direction of the first tweezers handle or the second tweezers handle itself, and a slider that can slide along the waist-shaped hole is provided in the waist-shaped hole, and a wedge and a hook are respectively connected on both sides of the slider, and the hook is located on the outer side of the first tweezers handle or the second tweezers handle, and the wedge is located on the inner side of the first tweezers handle or the second tweezers handle, and the tip of the wedge is facing the tail of the first tweezers handle and the second tweezers handle.
[0010] Furthermore, the surface of the wedge block is provided with an anti-slip layer made of elastic material.
[0011] Beneficial effects of the utility model:
[0012] The dental crown clamping tweezers of the present invention include a first tweezers handle, a second tweezers handle, a first tweezers beak and a second tweezers beak. The plane where the fitting surfaces of the first tweezers handle and the second tweezers handle are located is a symmetry plane. The first tweezers handle is located on the left side of the symmetry plane, and the second tweezers handle is located on the right side of the symmetry plane. The first tweezers beak and the second tweezers beak are both bent toward the symmetry plane and form an X-shaped cross structure at the symmetry plane, so that the front end of the first tweezers beak is located on the right side of the symmetry plane and the front end of the second tweezers beak is located on the left side of the symmetry plane. The first tweezers handle and the second tweezers handle have an elastic force that opens to both sides. Under the action of the elastic force, the front end of the first tweezers beak and the front end of the second tweezers beak are tightly fitted together to form a clamping force. When using the crown clamping tweezers of the present invention, the doctor only needs to press the tweezers handles on both sides when starting to clamp the crown, so that the first tweezers beak and the second tweezers beak can be separated from each other to clamp the crown. After clamping the crown, the force pressing the tweezers handles on both sides can be released so that the crown can be always clamped under the action of the elastic force of the tweezers handles on both sides, thereby effectively solving the technical problem of dentists needing to hold the tweezers handles tightly throughout the operation, which causes hand fatigue.

[0019] The following is a detailed description of the present invention with reference to the accompanying drawings:
[0020] like Figure 1 and Figure 2As shown, the crown clamping tweezers in this embodiment include a first tweezers handle 1, a second tweezers handle 2, a first tweezers beak 3 and a second tweezers beak 4, the tail of the first tweezers handle 1 and the second tweezers handle 2 are fixedly connected in a fitting manner, the first tweezers beak 3 and the second tweezers beak 4 are respectively arranged at the front end of the first tweezers handle 1 and the front end of the second tweezers handle 2, and are characterized in that: the plane where the fitting surfaces of the first tweezers handle 1 and the second tweezers handle 2 are located is a symmetry plane, the first tweezers handle 1 is located on the left side of the symmetry plane, the second tweezers handle 2 is located on the right side of the symmetry plane, and the left side and the right side are connected. Figure 1 The left and right sides correspond to each other, the first tweezers beak 3 and the second tweezers beak 4 are both bent toward the direction of the symmetry plane, and form an X-shaped cross structure at the symmetry plane, so that the front end of the first tweezers beak 3 is located on the right side of the symmetry plane, and the front end of the second tweezers beak 4 is located on the left side of the symmetry plane, and the first tweezers handle 1 and the second tweezers handle 2 have elastic force to open to both sides, and under the action of the elastic force, the front end of the first tweezers beak 3 and the front end of the second tweezers beak 4 are tightly fitted together to form a clamping force.
[0021] The principle of the dental crown clamping tweezers of the present invention is as follows: when the doctor needs to clamp the dental crown, he only needs to press the tweezers handles on both sides when starting to clamp the dental crown, so that the first tweezers beak and the second tweezers beak are separated from each other and can clamp the dental crown. After clamping the dental crown, the force of pressing the tweezers handles on both sides is released, so that the dental crown can be always clamped under the action of the elastic force of the tweezers handles on both sides, thereby solving the technical problem that dentists need to hold the tweezers handles tightly throughout the process of clamping the dental crown, which causes hand fatigue.
[0022] As a further improvement to the above technical solution, a retaining plate 5 is provided above the middle portion of each of the first and second beaks 3, 4. The two retaining plates 5 extend in the direction of the symmetry plane and are staggered relative to each other. When the crown is clamped and installed in the corresponding position in the oral cavity using the crown-clamping forceps, the retaining plates block the top of the crown, preventing it from sliding between the first and second beaks 3, 4 or falling out when pressed downward.
[0023] As a further improvement of the above technical solution, Figures 3 to 5As shown, a waist-shaped hole 9 is provided in the middle of the first tweezers handle 1 or the second tweezers handle 2 and along the length direction of the first tweezers handle 1 or the second tweezers handle 2. A slider 8 that can slide along the waist-shaped hole is provided in the waist-shaped hole. A wedge 6 and a hook 7 are connected to both sides of the slider 8. The hook 7 is located on the outer side of the first tweezers handle 1 or the second tweezers handle 2, and the wedge 6 is located on the inner side of the first tweezers handle 1 or the second tweezers handle 2. The tip of the wedge 6 faces the tail of the first tweezers handle 1 and the second tweezers handle 2. During the crown clamping process, if you want to increase the clamping force, you only need to pull the hook toward the tail end of the tweezers handle so that the wedge is embedded between the first tweezers handle 1 and the second tweezers handle 2, which can increase the tension of the first tweezers handle 1 and the second tweezers handle 2 toward the outside, that is, increase the clamping force between the first tweezers beak 3 and the second tweezers beak 4.
[0024] As a further improvement to the above technical solution, a non-slip layer made of elastic material is provided on the surface of the wedge 6. The purpose of providing the non-slip layer is that once the wedge 6 is inserted between the first tweezers handle 1 and the second tweezers handle 2, the wedge will not be easily withdrawn even if the hook is no longer pulled toward the tail end of the tweezers handle.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
