Description

Technical Field

[0001] The utility model relates to the technical field of medical tool equipment, and particularly relates to a special laminar rongeur for UBE surgery. Background Art

[0002] When performing UBE surgery, the biting section of the rongeur needs to be inserted into the spine to bite and clamp out the lamina therein. However, the biting section of the existing special laminar rongeur for UBE surgery is of a straight structure, while the patient's spine has a certain curvature. During actual operation, due to the straight structure of the rongeur, it cannot be well inserted into the spine to bite and clamp out the lamina therein.

[0003] Therefore, there is an urgent need for a special laminar rongeur for UBE surgery to solve the problem that the existing UBE surgery laminar rongeur cannot well bite and clamp out the lamina inside the patient. Summary of the Utility Model

[0004] The utility model provides a special laminar rongeur for UBE surgery to solve the problem that the existing UBE surgery laminar rongeur cannot well bite and clamp out the lamina inside the patient.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A special laminar rongeur for UBE surgery, comprising:

[0007] A fixed rear handle, on which a fixed arm is provided;

[0008] A movable front handle, which is hingedly arranged on the fixed rear handle;

[0009] A movable rod, which is telescopically arranged on the fixed arm. One end of the movable rod abuts against the end of the movable front handle. A first rod with a curvature is provided at one end of the fixed arm far away from the fixed rear handle. A second rod with a curvature is provided at one end of the movable rod far away from the fixed rear handle. The concave surfaces of the first rod and the second rod face the free end of the movable rod. The included angle between the tips of the first rod and the second rod and the fixed arm is 145° - 160°. The first rod and the second rod face away from the movable front handle, and the tips of the first rod and the second rod can approach each other to clamp the lamina.

[0010] Further, the movable front handle is hingedly connected to the fixed rear handle at one-third of its length;

[0011] A slideway is arranged inside the fixed arm. The movable rod is located inside the slideway. A bearing platform is arranged inside the slideway. A spring is sleeved on the movable rod. One end of the spring abuts against the surface of the bearing platform.

[0012] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] Since the first rod and the second rod of the present utility model have arcs and the included angles between the tips of the first rod and the second rod and the fixed arm are 145° - 160°, the first rod and the second rod face away from the movable front handle. Such a structure enables the present utility model to conveniently extend into the spine to clamp out the lamina therein. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 1 - fixed rear handle, 2 - fixed arm, 3 - movable front handle, 4 - movable rod, 5 - first rod, 6 - second rod, 7 - spring. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be described in detail below with reference to the accompanying drawings.

[0018] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] In this embodiment, a special lamina rongeur for UBE surgery is provided, as Figure 1 shown, including:

[0020] A fixed rear handle 1, on which a fixed arm 2 is provided;

[0021] A movable front handle 3, which is hingedly arranged on the fixed rear handle 1;

[0022] A movable rod 4, which is telescopically arranged on the fixed arm 2. One end of the movable rod 4 abuts against the end of the movable front handle 3. At the end of the fixed arm 2 away from the fixed rear handle 1, there is a first rod 5 with an arc. At the end of the movable rod 4 away from the fixed rear handle 1, there is a second rod 6 with an arc. The concave surfaces of the first rod 5 and the second rod 6 face the free end of the movable rod 4. The included angles between the tips of the first rod 5 and the second rod 6 and the fixed arm 2 are 145° - 160°. The first rod 5 and the second rod 6 face away from the movable front handle 3. The tips of the first rod 5 and the second rod 6 can approach each other to clamp the lamina.

[0023] Since the first rod 5 and the second rod 6 of the present utility model have arcs and the included angle between the tips of the first rod 5 and the second rod 6 and the fixed arm 2 is 145°-160°, the first rod 5 and the second rod 6 face away from the movable front handle 3. Such a structure enables the present utility model to conveniently extend into the spine to clamp out the lamina therein.

[0024] For further optimization of the above embodiment, the one-third position of the movable front handle 3 is hingedly connected to the fixed rear handle 1;

[0025] A slideway is arranged inside the fixed arm 2, the movable rod 4 is located inside the slideway, a bearing platform is arranged inside the slideway, a spring 7 is sleeved on the movable rod 4, and one end of the spring 7 abuts against the surface of the bearing platform.

[0026] During actual use, the movable front handle 3 and the fixed rear handle 1 are brought closer together, and one end of the movable front handle 3 pushes the movable rod 4 to move, so that the tip of the second rod 6 approaches the tip of the first rod 5 to clamp the lamina.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
