Description

Technical Field

[0001] The invention relates to a high-operability vertebral plate rongeur and a use method thereof, belonging to the field of medical instruments. Background Art

[0002] Vertebral lamina rongeurs are one of the important medical instruments in spinal surgery. However, in actual use, it has been found that the vertebral lamina rongeurs currently used have large forces when performing bone shearing and other operations during surgery, and substances such as tissue fluid attached to the bone surface, so that after the bone shearing is completed, the broken bones often cannot fall directly between the jaws of the vertebral lamina rongeurs. During the operation, medical staff need to use cleaning equipment to assist in cleaning the broken bones at the jaws of the vertebral lamina rongeurs. Although this can meet the needs of the operation, on the one hand, the efficiency of the operation is affected by the broken bone cleaning operation, and the efficiency of the operation is low; on the other hand, special medical staff need to be equipped to clean the vertebral lamina rongeurs, which leads to high labor intensity and relatively poor work flexibility for medical staff, seriously affecting the work efficiency and intensity of the operation.

[0003] In addition, current traditional lamina rongeurs are often unable to effectively clean the surgical surface when in use, causing the area to be cleaned to be easily disturbed by blood, tissue fluid, and soft tissue adhesion, thereby affecting the efficiency and accuracy of the surgical operation, and further making the subsequent cleaning of broken bones after shearing difficult.

[0004] Therefore, in order to solve this problem, it is urgent to develop a new vertebral plate bone rongeur device and use method to meet the needs of actual use. Summary of the Invention

[0005] In order to address the deficiencies in the prior art, the present invention provides a highly operable lamina bone-cutting forceps, which is flexible and convenient to use. On the one hand, it can assist in cleaning the surgical site during surgical operations, thereby improving surgical efficiency and reducing the risk of complications caused by incomplete wound cleaning; on the other hand, during use, it can quickly clean and purify the sheared bone, muscle tissue, and body fluids, which can effectively improve surgical efficiency, reduce the workload of medical staff during the operation, and improve the flexibility of medical staff during the operation.
