Description

Technical Field

[0001] This utility model relates to the field of orthodontic forceps technology, and in particular to an orthodontic forceps with easily replaceable forceps heads. Background Technology

[0002] Orthodontic instruments consist of orthodontic forceps, tweezers, and positioners. Orthodontic forceps, as an important medical instrument for orthodontic treatment, mainly consist of handles and heads. Generally, the handles control the movement of the heads via pins. When the orthodontic forceps are in use, pressing the handles brings the heads closer together, causing deformation in the corresponding positions of the braces. The patient then wears the adjusted braces, which rotate the teeth to be orthodontized to the normal position, thus achieving the purpose of orthodontic treatment.

[0003] Traditional orthodontic forceps typically have a one-piece design for the forceps head and handle. When adjusting braces, the forceps head is prone to wear. Worn forceps cannot accurately adjust the braces, affecting the orthodontic treatment. Furthermore, they also present problems such as cumbersome instrument management, high costs, and a heavy burden of sterilization. Utility Model Content

[0004] To address the technical problems associated with traditional orthodontic forceps, where the forceps head and handle are often integrated, resulting in cumbersome instrument management, high costs, and a heavy burden on sterilization, this utility model provides an orthodontic forceps with an easily replaceable forceps head.

[0005] This utility model is achieved using the following technical solution: an orthodontic forceps with an easy-to-change pliers head, comprising a pliers head and pliers handles, wherein the pliers handles are divided into an upper pliers handle and a lower pliers handle, the upper pliers handle and the lower pliers handle are configured as a pair of symmetrical cranks, and the upper pliers handle and the lower pliers handle are rotatably connected together by a pin, wherein the ends of the upper pliers handle and the lower pliers handle are provided with a detachable connecting component between them and the pliers head, the connecting component comprising a short post fixed to the ends of the upper pliers handle and the lower pliers handle, wherein a retaining pin is symmetrically fixed to the outer side of the short post, and a connecting sleeve is slidably and rotatably connected to the outer side of the short post, the connecting sleeve being fixed to the pliers handle.

[0006] The above technical solution connects the upper and lower handles and the forceps head through a connecting component, allowing for quick replacement of the required forceps head. Compared with traditional one-piece orthodontic forceps, only the forceps head needs to be replaced to meet the different needs of medical staff, avoiding the need to purchase multiple complete orthodontic forceps at the same time, thus reducing costs and sterilization burden.

[0007] As a further improvement to the above solution, the outer side of the connecting sleeve is symmetrically provided with a track for sliding the locking shaft; the end of the track is provided with an opening for limiting the locking shaft.

[0008] The above technical solution allows the opening at the end of the outer track of the connecting sleeve to ensure that the clasp on the outside of the short post remains within the opening and does not shift, thus ensuring that the orthodontic forceps will not loosen during surgery.

[0009] As a further improvement to the above solution, the top end of the short column is located inside the connecting sleeve and is fixedly connected to a first magnet. The connecting sleeve is provided with a second magnet that attracts the first magnet. An elastic component for releasing the locking pin limit is provided between the top end of the connecting sleeve and the second magnet.

[0010] Through the above technical solution, the setting of the first magnet and the second magnet can further stabilize the connection between the pliers head and the pliers handle; the elastic component set inside the connecting sleeve allows the pliers head to be pressed towards the pliers handle when different pliers heads need to be replaced, so that the clasp on the outside of the short post is disengaged from the opening, and then the connecting sleeve is rotated to disengage the clasp from the track.

[0011] As a further improvement to the above solution, the elastic component includes a circular plate fixed to one side of the second magnet, the circular plate sliding inside the connecting sleeve, and a compression spring fixed between the circular plate and the top of the connecting sleeve. Multiple limiting blocks for limiting the circular plate are fixed to the inner sidewall of the connecting sleeve, and the multiple limiting blocks are arranged in a circumferential array around the surface of the circular plate.

[0012] The above technical solution uses multiple limiting blocks fixed to the inner wall of the connecting sleeve to limit the internal disc when the pliers pull outward, making it easier for the first magnet and the second magnet to separate.

[0013] As a further improvement to the above solution, slots are provided on the two inner sides of the upper and lower clamp handles to facilitate the rotation of the clamp handles. The slots on the upper and lower clamp handles fit together, and the pin is located in the middle of the slots and the upper and lower clamp handles are rotatably connected to the outside of the pin.

[0014] As a further improvement to the above solution, an arc-shaped spring piece that contacts the upper clamp handle is fixed to the inner side of the lower clamp handle, and anti-slip textures are provided on the outer sides of both the upper and lower clamp handles.

[0015] The above technical solution provides anti-slip textures on the outer sides of both the upper and lower clamp handles, which can prevent slipping when holding the clamp handles. An arc-shaped spring is fixed to the inner side of the lower clamp handle, which contacts the upper clamp handle. After the medical staff presses the spring, the arc-shaped spring can drive the upper and lower clamp handles to return to their initial positions, making it easier to press again.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model connects the upper and lower pliers and the pliers head through a connecting component, enabling quick replacement of the required pliers head. Compared with traditional one-piece orthodontic pliers, only the pliers head needs to be replaced to meet the different needs of medical staff, avoiding the need to purchase multiple complete orthodontic pliers at the same time, thus reducing costs and sterilization burden.

[0018] 2. The opening at the end of the outer track of the connecting sleeve ensures that the clasp on the outside of the short post remains within the opening and does not shift, thus ensuring that the orthodontic forceps will not loosen during the operation by medical staff.

[0019] 3. Anti-slip textures are provided on the outer sides of both the upper and lower clamp handles to prevent slipping when holding the handles; an arc-shaped spring is fixed to the inner side of the lower clamp handle, which contacts the upper clamp handle, so that after the medical staff presses, the arc-shaped spring can drive the upper and lower clamp handles to return to their initial positions, making it easy to press again.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please combine Figures 1-4This embodiment of an orthodontic forceps with easily replaceable forceps heads includes a forceps head 1 and forceps handles. The forceps handles are divided into an upper forceps handle 2 and a lower forceps handle 3, which are configured as a pair of symmetrical cranks and are rotatably connected together by a pin 4. A detachable connecting component is provided between the ends of the upper forceps handles 2 and 3 and the forceps head 1. The connecting component includes a short post 5 fixed to the ends of the upper forceps handles 2 and 3, a retaining pin 6 symmetrically fixed to the outside of the short post 5, and a connecting sleeve 7 slidably and rotatably connected to the outside of the short post 5. The connecting sleeve 7 is fixed to the forceps handle. By providing a connecting component between the upper forceps handle 2, the lower forceps handle 3 and the forceps head 1, the forceps head 1 can be quickly replaced to meet the needs of medical staff at all times. Compared with traditional one-piece orthodontic forceps, it avoids the need to purchase multiple integrated orthodontic forceps at the same time, thereby reducing costs and sterilization burden.

[0028] Combination Figure 2 The outer side of the connecting sleeve 7 is symmetrically provided with a track 8 for sliding the clasp 6; the end of the track 8 is provided with an opening 9 for limiting the clasp 6; through the opening 9 at the end of the track 8 on the outer side of the connecting sleeve 7, the clasp 6 on the outer side of the short post 5 can be kept within the opening 9 without shifting, ensuring that the orthodontic forceps will not loosen during the operation of medical staff.

[0029] Combination Figure 3 The top of the short column 5 is located inside the connecting sleeve 7 and is fixedly connected to a first magnet 10. A second magnet 11, which attracts the first magnet 10, is disposed inside the connecting sleeve 7. An elastic component for releasing the locking pin 6 is disposed between the top of the connecting sleeve 7 and the second magnet 11. The elastic component includes a circular plate 12 fixedly connected to one side of the second magnet 11. The circular plate 12 slides inside the connecting sleeve 7, and a compression spring 13 is fixedly connected between the circular plate 12 and the top of the connecting sleeve 7. Multiple limiting blocks for limiting the circular plate 12 are fixedly connected to the inner wall of the connecting sleeve 7. 14. Multiple limiting blocks 14 are arranged in a circumferential array around the surface of the circular plate 12. When it is necessary to replace the pliers head 1, first pull the pliers head 1 outward so that the locking shaft 6 on the outside of the short column 5 is disengaged from the opening 9 at the end of the track 8. Then rotate the pliers head 1 to drive the locking shaft 6 on the outside of the short column 5 to slide out along the track 8 opened by the connecting sleeve 7. At this time, pull the pliers head 1 outward. Because of the multiple limiting blocks 14 fixed on the inner side wall of the connecting sleeve 7, the internal disc can be limited until the first magnet 10 and the second magnet 11 are disengaged, and the replacement of the pliers head 1 can be completed.

[0030] Combination Figure 1 and Figure 4The upper clamp handle 2 and the lower clamp handle 3 have slots 15 on their inner sides to facilitate rotation. The slots 15 on the upper clamp handle 2 and the lower clamp handle 3 fit together. The pin 4 is located in the middle of the slot 15 and the upper clamp handle 2 and the lower clamp handle 3 are rotatably connected to the outer side of the pin 4. An arc-shaped spring piece 16 that contacts the upper clamp handle 2 is fixed to the inner side of the lower clamp handle 3. Anti-slip textures 17 are provided on the outer sides of both the upper clamp handle 2 and the lower clamp handle 3. The anti-slip textures 17 on the outer sides of both the upper clamp handle 2 and the lower clamp handle 3 can prevent slipping when holding the clamp handles. The arc-shaped spring piece 16 that contacts the upper clamp handle 2 is fixed to the inner side of the lower clamp handle 3 so that after the medical staff presses, the arc-shaped spring piece 16 can drive the upper clamp handle 2 and the lower clamp handle 3 to return to their initial position, which is convenient for the next press.

[0031] The implementation principle of an orthodontic forceps with an easy-to-change forceps head in this application embodiment is as follows:

[0032] When it is necessary to replace the pliers head 1, first pull the pliers head 1 outward so that the short post 5 fixed to the ends of the upper pliers handle 2 and the lower pliers handle 3 can move along the pulling direction, so that the retaining pin 6 symmetrically fixed to the outside of the short post 5 disengages from the opening 9 at the end of the track 8 opened on the outside of the connecting sleeve 7 connected to it. Then rotate the pliers head 1 to drive the retaining pin 6 on the outside of the short post 5 to slide out along the track 8 opened on the connecting sleeve 7. At this time, pull the pliers head 1 outward again. Because the top of the short post 5 and the inside of the connecting sleeve 7 are provided with a first magnet 10 and a second magnet 11 that attract each other, and multiple limiting blocks 14 fixed to the inner wall of the connecting sleeve 7, when the pliers head 1 is pulled outward again, the multiple limiting blocks 14 fixed to the inner wall of the connecting sleeve 7 can limit the circular plate 12 fixed to one side of the second magnet 11 until the first magnet 10 and the second magnet 11 disengage, and the replacement of the pliers head 1 is completed.

[0033] Because a compression spring 13 is fixed between the top of the connecting sleeve 7 and the circular plate 12, when a new pliers head 1 is installed and the locking shaft 6 on the outside of the short column 5 is located at the end of the track 8, when the pliers head 1 is pressed towards the pliers handle again, the compression spring 13 inside the connecting sleeve 7 is compressed at the same time, and the locking shaft 6 is driven to lock into the opening 9 for limiting. At the same time, the first magnet 10 fixed at the top of the short column 5 and the second magnet 11 fixed at the bottom of the circular plate 12 attract each other.

[0034] Anti-slip grooves 17 are provided on the outer sides of both the upper clamp handle 2 and the lower clamp handle 3 to prevent slipping when holding the clamp handles. An arc-shaped spring piece 16 is fixed to the inner side of the lower clamp handle 3 to contact the upper clamp handle 2. After the medical staff presses, the arc-shaped spring piece 16 can drive the upper clamp handle 2 and the lower clamp handle 3 to return to their initial positions, which is convenient for the next press.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
