Description

Technical Field

[0001] The utility model relates to a pair of pliers, in particular to a titanium plate cutting pliers. Background Art

[0002] During the surgical treatment of maxillofacial fractures, after reducing the displaced fractures, we need to use titanium plates for rigid internal fixation. The finished titanium plates are usually relatively long and need to be cut according to specific situations.

[0003] In the prior art, due to the lack of special cutting pliers, doctors use conventional flat-nose pliers in the prior art to cut titanium plates. After the titanium plate is cut, the two sides of the cut end are two sharp right angles. The cross-section is relatively sharp and can cause damage to the surrounding soft tissues when placing the titanium plate. Especially during deep operation or when the incision is small, the sharp cross-section may damage important nerves and blood vessels and scrape and tear the surrounding soft tissues, affecting their positioning. Summary of the Utility Model

Detailed implementation manners

[0019] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and cannot be construed as a limitation to the present utility model.

[0020] Embodiments of the present utility model: As Figures 1 - 4 shown, a titanium plate cutting pliers includes a first pliers handle 1, a second pliers handle 2, a first pliers head 3 and a second pliers head 4. The first pliers handle 1 and the second pliers handle 2 are hingedly connected through a hinge shaft 5. The first pliers head 3 is fixedly arranged on the first pliers handle 1, and the second pliers head 4 is fixedly arranged on the second pliers handle 2. The first pliers head 3 and the second pliers head 4 are arranged in a staggered manner. A titanium plate positioning structure is arranged on the first pliers head 3, and a semicircular cutting groove 13 is arranged on the second pliers head 4.

[0021] By arranging a titanium plate positioning structure on the first pliers head 3, the titanium plate 9 can be positioned. Through the arrangement of the semicircular cutting groove 13, the cutting position can be circular arc, so that the end of the titanium plate 9 will not cause abrasion and scratch to the surrounding tissues.

[0022] In a specific implementation manner, the titanium plate positioning structure includes a semicircular support platform 6 and a positioning column 7. The semicircular support platform 6 and the first pliers head 3 are of an integral structure. The semicircular support platform 6 is located on one side of the first pliers head 3 and is matched with the semicircular cutting groove 13. The positioning column 7 is fixedly arranged at one end of the semicircular support platform 6 facing the semicircular cutting groove 13, and the positioning column 7 is coaxial with the semicircular support platform 6.

[0023] As Figure 2 shown, when the first pliers head 3 and the second pliers head 4 are closed, the semicircular support platform 6, the semicircular cutting groove 13 and the positioning column 7 are in a coaxial state. At this time, the top surface of the first pliers head 3 is flush with the bottom surface of the second pliers head 4, and at the same time, the titanium plate 9 is cut through the cooperation of the semicircular cutting groove 13 and the semicircular support platform 6.

[0024] Furthermore, the titanium plate positioning structure further includes a limiting plate 8. One end of the limiting plate 8 is formed with an inclined connecting portion, and this connecting portion is fixedly connected with the first pliers head 3. The limiting plate 8 and the positioning column 7 are located on the same side. The limiting plate 8 is parallel to the surface of the first pliers head 3, and the distance between the bottom surface of the limiting plate 8 and the top surface of the first pliers head 3 is equal to the thickness of the titanium plate 9.

[0025] When in use, separate the first jaw 3 from the second jaw 4, then place the circular plate body at the tip position on the positioning post 7, and then rotate the titanium plate 9 so that the titanium plate 9 is clamped between the limiting plate 8 and the first jaw 3. Then operate the first jaw handle 1 and the second jaw handle 2 to close the first jaw 3 and the second jaw 4, completing the shearing of the titanium plate 9.

[0026] Through the settings of the limiting plate 8 and the positioning post 7, the positioning of the titanium plate 9 by hand is replaced, making it easier to shear the titanium plate 9.

[0027] Furthermore, the diameter of the positioning post 7 is equal to the inner diameter of the circular plate body on the titanium plate 9, the diameter of the semi-circular support platform 6 is equal to the outer diameter of the circular plate body on the titanium plate 9, and the diameter of the semi-circular cutting groove 13 is equal to the diameter of the semi-circular support platform 6.

[0028] Furthermore, anti-slip grooves 10 are formed on the outer walls of both the first jaw handle 1 and the second jaw handle 2. Through the settings of the anti-slip grooves 10, the anti-slip effect can be effectively achieved, preventing the hand from slipping during operation. In this embodiment, both the first jaw handle 1 and the second jaw handle 2 adopt an arc design, which can improve the comfort during operation.

[0029] Even further, an elastic support structure is provided between the first jaw handle 1 and the second jaw handle 2. The elastic support structure includes a first arc-shaped spring plate 11 and a second arc-shaped spring plate 12. The first arc-shaped spring plate 11 and the second arc-shaped spring plate 12 are symmetrically arranged. One end of the first arc-shaped spring plate 11 is fixedly connected to the first jaw handle 1, the other end of the first arc-shaped spring plate 11 is fixedly connected to one end of the second arc-shaped spring plate 12, and the other end of the second arc-shaped spring plate 12 is fixedly connected to the second jaw handle 2.

[0030] The setting of the first arc-shaped spring plate 11 and the second arc-shaped spring plate 12 can make the first jaw handle 1 and the second jaw handle 2 automatically move away from each other, keeping the first jaw 3 and the second jaw 4 in an open state without applying external force, which is convenient for the installation of the titanium plate 9.

[0031] The working principle of the present utility model: In the natural state, under the support of the first arc-shaped spring plate 11 and the second arc-shaped spring plate 12, the first jaw handle 1 and the second jaw handle 2 are separated from each other, making the first jaw 3 and the second jaw 4 in an open state. If two circular plate bodies need to be cut from the titanium plate 9, only need to install the third circular plate body on the positioning post 7, and then rotate the titanium plate 9 so that the titanium plate 9 is clamped between the limiting plate 8 and the first jaw 3 (as Figure 4In the state shown, at this time, the semi-circular support platform 6 on the first jaw 3 supports the third circular ring-shaped plate body. Squeeze the first jaw handle 1 and the second jaw handle 2 by hand to make the first jaw 3 and the second jaw 4 approach each other. When the bottom surface of the second jaw 4 contacts the titanium plate 9, the titanium plate 9 will not be pressed out of shape under the action of the limiting plate 8. The first jaw 3 and the second jaw 4 continue to approach, and the titanium plate is cut off under the cooperation of the semi-circular cutting groove 13 and the semi-circular support platform 6. Release the first jaw handle 1 and the second jaw handle 2, and the first jaw handle 1 and the second jaw handle 2 move away from each other under the supporting action of the first arc-shaped spring plate 11 and the second arc-shaped spring plate 12, and then the remaining titanium plate 9 can be removed.

[0032] The structure, features and effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above are only the preferred embodiments of the present utility model, but the present utility model is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present utility model, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the description and the drawings, shall be within the protection scope of the present utility model.
