Description

Technical Field

[0001] This utility model relates to the field of equipment for unilateral dual-channel spinal endoscopy technology, and particularly to a forceps device for unilateral dual-channel spinal endoscopy technology. Background Technology

[0002] UBE (Unilateral Dual-Channel Endoscopic Behavior) is an emerging spinal endoscopic technique. This technique features two channels: one providing the surgical field and continuous irrigation, and the other for instrument manipulation. Unilateral dual-channel endoscopic surgery offers independent channels for the endoscope and instruments, increasing the range of motion and space for both the lens and surgical instruments, resulting in a clear intraoperative view. It allows the use of arthroscopy and conventional spinal surgical instruments, facilitating the procedure. UBE is suitable for degenerative lesions of the cervical, thoracic, and lumbar spine, and can be used for discectomy and interbody fusion. It offers advantages such as minimal invasiveness, short operation time, minimal bleeding, and short hospital stay.

[0003] There are many instruments related to UBE unilateral dual-channel endoscopy technology, including many forceps devices such as nucleus pulposus forceps and plate forceps. These forceps devices are generally equipped with elastic elements to keep the forceps in an open state automatically. However, the elastic elements of existing forceps devices are fixed and cannot be adjusted, which means that the elastic opening force of the forceps device is also fixed. Different operators have different adaptability to the grip force of the forceps. Therefore, existing forceps devices cannot meet the operating requirements of different operators and cannot allow operators to operate very smoothly and comfortably.

[0004] Therefore, there is a need to provide a forceps device for unilateral dual-channel spinal endoscopy to solve the above-mentioned technical problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The directional terms mentioned in this utility model, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", "top" and "bottom", are only for reference to the orientation of the accompanying drawings. The directional terms used are for the purpose of explaining and understanding this utility model, and are not intended to limit this utility model.

[0026] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, a connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components.

[0028] In existing pliers devices, the elastic components are fixed and cannot be adjusted, resulting in a fixed elastic opening force. However, different operators have different gripping strength requirements for pliers, so existing pliers devices cannot meet the operational requirements of different operators and cannot allow operators to operate them smoothly and comfortably.

[0029] The following is a first embodiment of a forceps device for unilateral dual-channel spinal endoscopy that can solve the above-mentioned technical problems provided by this utility model.

[0030] Please refer to Figure 1 In the figure, structurally similar units are represented by the same label.

[0031] This embodiment provides a forceps device for unilateral dual-channel spinal endoscopy, which includes: a slide bar 11, a movable forceps 14, a fixed forceps 15, a fixed handle bar 12, a movable handle bar 13, and an elastic element.

[0032] The fixed clamp 15 is fixedly disposed at one end of the fixed handle rod 12, the movable clamp 14 is rotatably disposed at the end of the fixed handle rod 12 near the fixed clamp 15, one end of the movable handle rod 13 is rotatably connected to the end of the fixed handle rod 12 away from the fixed clamp 15, the slide rod 11 is slidably connected to the fixed handle rod 12, and the two ends of the slide rod 11 are respectively connected to the movable clamp 14 and the movable handle rod 13, so that by controlling the rotation of the movable handle rod 13, the slide rod 11 is driven to slide, thereby driving the movable clamp 14 and the fixed clamp 15 to open and close.

[0033] The elastic element is adjustablely positioned between the fixed handle rod 12 and the movable handle rod 13. The elastic element is used to open up the movable handle rod 13 and the fixed handle rod 12. The distance between different positions of the fixed handle rod 12 and the movable handle rod 13 is different. Therefore, by adjusting the position of the elastic element, the elastic force exerted by the elastic element on the fixed handle rod 12 and the movable handle rod 13 will be different, thereby adjusting the opening force between the movable handle rod 13 and the fixed handle rod 12 accordingly.

[0034] Please refer to Figure 1 and Figure 2 In this embodiment, the elastic element is a spring 161. The forceps device for unilateral dual-channel spinal endoscopy also includes a connector 17. One end of the spring 161 is slidably connected to the fixed handle rod 12 via a connector 17, and the other end of the spring 161 is slidably connected to the movable handle rod 13 via a connector 17. This allows the position of the spring 161 to be adjusted by adjusting the position of the connector 17.

[0035] Specifically, the connector 17 includes a first elastic rubber ring 171 and a connecting plate 172. The first elastic rubber ring 171 is slidably sleeved on the fixed handle rod 12 or slidably sleeved on the movable handle rod 13. The connecting plate 172 is fixedly connected to the first elastic rubber ring 171 and is connected to the spring 161. The connecting plate 172 can stably contact one side of the fixed handle rod 12 or the movable handle rod 13. It should be noted that the fixed handle rod 12 and the movable handle rod 13 in the figure are only schematic diagrams. Preferably, the parts of the fixed handle rod 12 and the movable handle rod 13 that are sleeved with the first elastic rubber ring 171 have the same outer contour size so that after the first elastic rubber ring 171 is slidably adjusted, it can still maintain a stable connection with the fixed handle rod 12 or the movable handle rod 13.

[0036] Preferably, a first positioning block 173 is provided on one side of the connecting plate 172, and multiple first positioning grooves 121 for positioning and engaging with the first positioning block 173 are provided on both the fixed handle rod 12 and the movable handle. Under the tension of the first elastic rubber ring 171, the first positioning block 173 can maintain a stable engagement with the first positioning groove 121, resulting in a stable structure.

[0037] In this embodiment, a connecting post 174 or a connecting hole for connecting to the spring 161 can be provided on the connecting plate 172 to achieve a stable connection between the spring 161 and the connecting plate 172.

[0038] Working principle: Before use, the forceps device of the unilateral dual-channel spinal endoscopy technology in this embodiment can push the connecting plate 172 to move away from the fixed handle rod 12 or away from the movable handle rod 13, and at the same time pull the first elastic rubber ring 171 and the connecting plate 172 to move, thereby adjusting the position of the connecting piece 17. After the positions of the connecting pieces 17 on the fixed handle rod 12 and the movable handle rod 13 are adjusted, the position of the spring 161 is also adjusted, thereby adjusting the opening force between the movable handle rod 13 and the fixed handle rod 12, which is more suitable for the operating habits of the corresponding operators, so that different operators can operate the forceps device more conveniently and comfortably.

[0039] Please refer to Figure 3 The following is a second embodiment of a forceps device for unilateral dual-channel spinal endoscopy provided by this utility model, which can solve the above-mentioned technical problems. The main difference between the second embodiment and the first embodiment lies in the structure of the elastic element; all other structures are the same. The structures identical to those in the first embodiment will not be described again.

[0040] The elastic element in this embodiment includes a first spring piece 1621 and a second spring piece 1622. One end of the first spring piece 1621 is movably connected to the fixed handle rod 12, and one end of the second spring piece 1622 is connected to the movable handle rod 13. The end of the first spring piece 1621 away from the fixed handle rod 12 is connected to the end of the second spring piece 1622 away from the movable handle rod 13. In this way, the first spring piece 1621 and the second spring piece 1622 can elastically separate the fixed handle rod 12 and the movable handle rod 13.

[0041] The first spring piece 1621 has a second elastic rubber ring 18 that slides and engages with the fixed handle rod 12 at one end. The position of the first spring piece 1621 is adjusted by sliding and adjusting the position of the second elastic rubber ring 18. The second spring piece 1622 has a third elastic rubber ring 19 that slides and engages with the movable handle rod 13 at one end. The position of the second spring piece 1622 is adjusted by sliding and adjusting the position of the third elastic rubber ring 19.

[0042] It should be noted that the fixed handle rod 12 and the movable handle rod 13 in the figure are only schematic diagrams. The part of the rod segment on the fixed handle rod 12 that is fitted with the second elastic rubber ring 18 and the part of the rod segment on the movable handle rod 13 that is fitted with the third elastic rubber ring 19 are preferably of the same outer contour size, so that the second elastic rubber ring 18 can still maintain a stable connection with the fixed handle rod 12 after sliding adjustment, and the third elastic rubber ring 19 can still maintain a stable connection with the movable handle rod 13 after sliding adjustment.

[0043] Furthermore, a second positioning block is provided on one side of the first spring piece 1621, and multiple second positioning grooves are provided on the fixed handle rod 12 for positioning and engaging with the second positioning block. A third positioning block is provided on one side of the second spring piece 1622, and multiple third positioning grooves are provided on the movable handle rod 13 for positioning and engaging with the third positioning block. Under the tension of the second elastic rubber ring 18, the second positioning block can maintain a stable engagement with the second positioning groove, resulting in structural stability. Under the tension of the third elastic rubber ring 19, the third positioning block can maintain a stable engagement with the third positioning groove, resulting in structural stability.

[0044] The configuration structure of the second and third positioning blocks can refer to the configuration structure of the first positioning block 173 in the first embodiment, that is, refer to... Figure 2 .

[0045] Optionally, the first spring 1621 and the second spring 1622 can be rotatably connected by a pivot. While ensuring the connection between the first spring 1621 and the second spring, the relative movement between the fixed handle rod 12 and the movable handle rod 13 can be accommodated.

[0046] Please refer to Figure 4 Optionally, one end of the first spring 1621 is provided with a limiting groove 16211, and one end of the second spring 1622 is provided with a limiting block 16221, with the limiting block 16221 movably limited within the limiting groove 16211. Similarly, while ensuring connection between the first spring 1621 and the second spring, it can accommodate the relative movement between the fixed handle rod 12 and the movable handle rod 13.

[0047] When the position of the elastic element needs to be adjusted, push the first spring piece 1621 to move away from the fixed handle rod 12, then pull the second elastic rubber ring 18 and the first spring piece 1621 to move, then push the second spring piece 1622 to move away from the movable handle rod 13, and then pull the third elastic rubber ring 19 and the second spring piece 1622 to move. In this way, the position of the elastic element can be adjusted, thereby achieving the purpose of adjusting the opening force between the movable handle rod 13 and the fixed handle rod 12.

[0048] The forceps device of this invention for unilateral dual-channel spinal endoscopy technology has an adjustable elastic element positioned between the fixed handle and the movable handle. This allows for adjustment of the opening force between the movable and fixed handles by adjusting the position of the elastic element, making it easier and more comfortable for different operators to operate the forceps device.

[0049] In summary, although the present invention has been disclosed above with reference to the above embodiments, the above embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
