Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a crown holder. Background Art

[0002] With the development of modern medicine, endodontitis is a common oral disease. At present, the main treatment method for endodontitis is root canal treatment. After root canal treatment, the hardness of the tooth decreases, and it is necessary to restore the normal function of the tooth through crown restoration. Therefore, in oral treatment, full crown restoration is a common tooth treatment method. However, during the trial crown and crown wearing processes, due to the small size and relatively smooth surface of the crown, or the small mouth opening of the patient, there are difficulties in the trial crown and crown wearing processes, and it may cause the crown to fall into the patient's mouth, and even the risk of accidental swallowing or aspiration. At present, during the trial crown and crown wearing processes, in the case of difficult-to-operate posterior teeth or patients with a small mouth opening, doctors may use forceps to hold the crown. However, it is easy for the forceps to drop the crown. Summary of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of this, the embodiments of this specification provide a crown holder that is not easy to drop the held crown, is convenient to operate, and can be used for difficult-to-operate posterior teeth or patients with a small mouth opening.

[0005] (2) Technical Solutions

[0006] To solve the above technical problems, the utility model provides the following technical solutions: A crown holder includes a main body. The main body includes a left clamping part and a right clamping part, which are arranged oppositely. A left detachable green pad is sleeved on the outer end of the left clamping part, and right detachable green pads are sleeved on the outer ends of the right clamping part. The left detachable green pad and the right detachable green pads are symmetrically arranged along the central axis of the main body. When the left clamping part and the right clamping part are in a normal state, the distance between the left detachable green pad and the right detachable green pads is less than the width of the crown. A restoring deformation component is arranged between the left clamping part and the right clamping part. The main body includes a control component. By controlling the control component, the left detachable green pad and the right detachable green pads move relatively away from each other. When the control of the control component is released, the restoring deformation component makes the left detachable green pad and the right detachable green pads return to the normal state.

[0007] Compared with the prior art, the advantages of the present utility model are as follows: Through the arrangement of the left detachable green pad and the right detachable green pad, the friction force is increased when clamping the dental crown, and the clamped dental crown is not easily detached, improving the safety of clamping the dental crown. Since the left detachable green pad and the right detachable green pad are detachably arranged, the left detachable green pad and the right detachable green pad can be replaced and disinfected for repeated use. At the same time, through the deformation recovery component, the left clamping part and the right clamping part maintain a moving trend in the opposite direction, enabling better and more stable clamping of the dental crown. The opening size between the left clamping part and the right clamping part can be adjusted through the control component.

[0008] In some embodiments, the control component includes a pressing rod, a connecting piece, a left connecting rod, and a right connecting rod. The main body includes a fixed seat. The inner end of the left clamping part is hinged to the left end of the fixed seat, and the inner end of the right clamping part is hinged to the right end of the fixed seat. A through hole is provided in the middle of the fixed seat, and the pressing rod is inserted into the through hole. The inner end of the pressing rod is fixedly connected to the middle of the connecting piece. The left end of the connecting piece is hinged to one end of the left connecting rod, and the right end of the connecting piece is hinged to one end of the right connecting rod. The other end of the left connecting rod is hinged to the middle of the left clamping part, and the other end of the right connecting rod is hinged to the middle of the right clamping part. Through the above improvement, by pressing the pressing rod, the connecting piece is pushed to move, thereby driving one end of the left connecting rod and the right connecting rod to move, realizing the relative separation of the left clamping part and the right clamping part. The operation is simple and convenient, and the stability is strong.

[0009] In some embodiments, the deformation recovery component includes a return spring. The return spring is sleeved on the pressing rod, and both ends of the return spring are respectively connected to the inner end of the fixed seat and the inner end of the connecting piece. Through the above improvement, when the moving part moves outward, the return spring is stretched. When the pressing rod is released, the return spring recovers its deformation, driving the left clamping part and the right clamping part to move towards each other with a strong clamping force.

[0010] In some embodiments, the control component includes a left handle and a right handle. The left handle is installed at the inner end of the left clamping part, and the right handle is installed at the inner end of the right clamping part. Through the above improvement, by controlling the left handle and the right handle to move towards each other, the left clamping part and the right clamping part are relatively opened.

[0011] In some embodiments, the deformation recovery component includes an arc-shaped elastic member. The arc-shaped elastic member is arranged between the left clamping part and the right clamping part. One end of the arc-shaped elastic member is connected to the middle of the left clamping part, and the other end of the arc-shaped elastic member is connected to the middle of the right clamping part. Through the above improvement, when the left clamping part and the right clamping part are relatively opened, the arc-shaped elastic member deforms. As the left clamping part and the right clamping part are opened synchronously, when the left handle and the right handle are released, the arc-shaped elastic member recovers its deformation, and the left clamping part and the right clamping part cause the main body to clamp the dental crown.

[0012] In some embodiments, circular mounting grooves are provided on both the left detachable green pad and the right detachable green pad. The circular mounting grooves are respectively in a tight fit with the left protruding part of the left clamping part and the right protruding part of the right clamping part. Through the above improvement, by matching the circular mounting grooves with the left protruding part and the right protruding part respectively, the detachable setting of the left detachable green pad and the right detachable green pad is realized.

[0013] In some embodiments, square mounting grooves are provided on both the left detachable green pad and the right detachable green pad. The square mounting grooves are respectively matched with the left protruding part of the left clamping part and the right protruding part of the right clamping part. Through the above improvement, by matching the square mounting grooves with the left protruding part and the right protruding part respectively, the detachable setting of the left detachable green pad and the right detachable green pad is realized. At the same time, the setting of the square mounting grooves prevents the left detachable green pad and the right detachable green pad from rotating.

[0014] (III) Beneficial effects

[0015] A crown gripper provided by the present utility model, through the settings of the left detachable green pad and the right detachable green pad, improves the friction force when gripping the crown, making it not easy for the crown to fall off when being gripped, and improving the safety of gripping the crown; the circular mounting grooves or square mounting grooves provided on both the left detachable green pad and the right detachable green pad are matched with the left protruding part of the left clamping part and the right protruding part of the right clamping part, so that the left detachable green pad and the right detachable green pad can be replaced and disinfected and reused; by pressing the pressing rod, the connecting piece is pushed to move, thereby driving one end of the left connecting rod and the right connecting rod to move, realizing the relative separation of the left clamping part and the right clamping part, with simple and convenient operation and strong stability; when the moving part moves outward, the return spring is stretched, and when the pressing rod is released, the return spring restores its deformation, driving the left clamping part and the right clamping part to move towards each other with a strong clamping force.
