Description

Technical Field

[0001] This utility model relates to the field of surgical bone saw technology, specifically a bone saw for orthopedic clinical surgery. Background Technology

[0002] A reciprocating saw is a highly efficient orthopedic surgical tool. Its reciprocating motion can quickly and accurately cut bone tissue, making it an indispensable tool in orthopedic surgery. Bone saws are usually equipped with a powerful electric motor or battery-driven system to provide the power required for cutting. To meet different surgical needs, bone saws are also usually equipped with a variety of accessories and attachments, such as saw blades of different sizes, dust collection systems, and lighting devices, to assist in the smooth progress of the surgery.

[0003] For example, the bone saw for orthopedic clinical surgery disclosed in the authorization announcement number CN221383678U includes a movable plate, multiple fixed blocks are symmetrically installed on the top surface of the movable plate, and a sliding groove is opened on the opposite side of each pair of fixed blocks. A sliding rod is longitudinally installed in the inner cavity of each of the multiple sliding grooves. One of the sliding rods is rotatably connected to the top surface and bottom surface of the inner cavity of the sliding groove, and the top end of the sliding rod passes through the fixed block and is fixedly connected to a handle. A semi-circular clamping block is symmetrically arranged between two fixed blocks. Slider blocks adapted to the sliding groove are symmetrically installed on the two sides of the upper semi-circular clamping block, and a sliding hole is opened on the top surface of the two sliders. A first bolt passes through the top surface of the upper semi-circular clamping block, and a semi-circular pressure block is rotatably connected to one end of the first bolt in the inner cavity of the semi-circular clamping block.

[0004] Although it enables clamping and fixing of patients with small bones, preventing the bones from vibrating during amputation and thus reducing the risk to the patient during amputation, and making it easy to place the patient's bones between the two semi-circular clamps, the handle makes it easy for staff to drive the slide bar to rotate, thereby moving the semi-circular clamps.

[0005] However, this does not solve the problem that existing surgical bone saws of this type are generally not conducive to reciprocating rotation for bone sawing, are not easy to drive with stable mechanical transmission, and are not convenient to replace the bone saw teeth, thus affecting the working efficiency of the surgical bone saw and the convenience of replacing the bone saw teeth.
