Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to an omnidirectional vertebral plate clamp used for a transforaminal endoscopic view. Background Art

[0002] During perforaminal endoscopic lumbar discectomy, the lamina forceps can be used to remove the lamina through a sleeve. However, due to its straight-tube structure, the manipulation range is limited and 360° resection cannot be achieved. This restricts the control direction and the resection operation, which can easily lead to incomplete resection. Utility Model Content

[0003] The utility model aims to provide an omnidirectional vertebral plate clamp for intervertebral foraminal endoscope to solve the technical problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the specific technical solution of the utility model is as follows: an omnidirectional lamina pliers for intervertebral foraminal endoscopy, comprising a bracket, a fixed handle is provided at the bottom of the rear end of the bracket, a movable handle is provided at the bottom of the bracket and is distributed corresponding to the fixed handle, a fixed tube is provided at the top of the bracket, a clamp tube that can rotate freely with the fixed tube is provided at the front end of the fixed tube, and a locking mechanism for limiting the rotation of the clamp tube is provided on the fixed tube.

[0005] Preferably, the rear end of the clamp tube extends to the front end inner cavity of the fixed tube and is rotatably connected thereto, and a rotating block is sleeved on the clamp tube near the fixed tube.

[0006] Preferably, the rotating block is fixedly connected to the clamp pipe, and the rotating block is a circular structure.

[0007] Preferably, the locking mechanism includes a support seat fixedly connected to the upper surface of the fixed tube, a threaded block is provided at the top of the support seat, a stud is threadedly connected to the threaded block, the end of the stud contacts the side wall of the rotating block, and a knob is provided at the end of the stud away from the rotating block.

[0008] Preferably, the rotating block is provided with an annular limiting groove on one end surface of the stud, and the limiting groove is cocentric with the fixing tube, and the end of the stud extends into the limiting groove.

[0009] Preferably, the side walls of the rotating block and the knob are both provided with anti-slip grooves.

[0010] The utility model is an omnidirectional lamina clamp for intervertebral foraminal endoscopy, which has the following advantages:

[0011] 1. The utility model provides a rotatable connection between the clamp tube and the fixed tube, which facilitates 360-degree rotation of the clamp tube, thereby facilitating 360-degree rotation of the operating head of the clamp tube, thereby increasing the operating range of the operating head, making laminectomy more thorough and facilitating surgery for orthopedic surgeons.

[0012] 2. After the rotating block is rotated, the stud can be rotated by turning the knob, so that the end of the stud is in close contact with the side wall of the rotating block, which can effectively prevent the rotating block from rotating privately and improve the stability of the structure.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0021] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0022] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the omnidirectional lamina forceps for transforaminal endoscopy of the present invention in conjunction with the accompanying drawings.

[0024] like Figure 1-3 As shown, the utility model discloses an omnidirectional laminar forceps for transforaminal endoscopic lumbar discectomy, comprising a bracket 1, a fixed handle 2 disposed at the rear bottom of the bracket 1, a movable handle 3 disposed at the bottom of the bracket 1 corresponding to the fixed handle 2, a fixed tube 4 disposed at the top of the bracket 1, a clamp tube 5 rotatable therewith disposed at the front end of the fixed tube 4, the rear end of the clamp tube 5 extending into the front end lumen of the fixed tube 4 and being rotatably connected thereto, and a rotating block 6 sleeved on the clamp tube 5 near the fixed tube 4. The rotatable connection between the clamp tube 5 and the fixed tube 4 facilitates 360-degree rotation of the clamp tube 5, thereby facilitating 360-degree rotation of the operating head of the clamp tube 5, thereby increasing the operating range of the operating head, making laminectomy more thorough and facilitating the orthopedic surgeon's surgery. The rotating block 6 is fixedly connected to the clamp tube 5 and has a circular structure. By setting the rotating block 6, the clamp tube 5 can be rotated by turning the rotating block 6.

[0025] The fixed tube 4 is provided with a locking mechanism 7 for limiting the rotation of the clamp tube 5. The locking mechanism 7 includes a support base 9 fixedly connected to the upper surface of the fixed tube 4. A threaded block 10 is provided at the top of the support base 9. A stud 11 is threadedly connected to the threaded block 10. The end of the stud 11 contacts the side wall of the rotating block 6. A knob 12 is provided on the end of the stud 11 away from the rotating block 6. After the rotating block 6 is rotated, the stud 11 can be rotated by turning the knob 12, so that the end of the stud 11 contacts the side wall of the rotating block 6, effectively preventing the rotating block 6 from rotating without authorization and improving the stability of the structure. The rotating block 6 is provided with an annular limiting groove 8 on one end of the stud 11. The limiting groove 8 is concentric with the fixed tube 4. The end of the stud 11 extends into the limiting groove 8. The provision of the limiting groove 8 increases the friction between the stud 11 and the rotating block 6, thereby allowing the stud 11 to lock the rotating block 6. The side walls of the rotating block 6 and the knob 12 are both provided with anti-slip grooves to facilitate the rotation of the rotating block 6 and the knob 12.

[0026] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
