Problems solved by technology
[0008] (1) The positioning accuracy of the existing orthopedic saw for orthopedic surgery does not meet the requirements of modern minimally invasive surgery at the use end of the chainsaw blade, and the positioning of the chainsaw needs to be improved;
[0009] (2) The existing orthopedic saws for orthopedic surgery use a complex control system structure, relatively backward control of the speed of the chainsaw, and large vibration amplitudes, which easily cause large trauma to the chainsaw

The invention discloses a special orthopedic operation saw which comprises an insulation handle, a fixed part, a speed reduction device and a zero-position positioning device. Two side shells of the insulation handle are connected in a clamped manner to form a control chamber, the fixed part is connected on the lower portion of the insulation handle, the speed reduction device is fixedly mounted on the upper portion of the insulation handle, a driving shaft is connected at the axial end of the speed reduction device, the zero-position positioning device is axially connected at the axial end ofthe driving shaft, and an electric saw web is axially connected at the left end of the zero-position positioning device through a motor coding component. The whole saw is provided with the zero-position positioning device and the speed reduction device, positioning errors are low by a positioning system based on a Hall switch, positioning is accurate and stable, the an accurate movement referenceposition is provided for a whole control system, so that the positioning accuracy of the whole electric saw web is ensured, vice-damage to operations is reduced, injury caused by the electric saw isavoided in the use process, and the pain and the financial burden of a patient are relieved.
Description
technical field [0001] The invention relates to the field of orthopedic surgery, in particular to a special orthopedic saw for orthopedic surgery. Background technique [0002] Surgery is the main treatment method in orthopedics, and bone saw is a commonly used medical device in orthopedics surgery. The saw blade of the existing bone saw only has serrations on one side. During the operation, the doctor pulls the saw blade back and forth by hand to saw the bone, which is time-consuming, labor-intensive, and takes a long time to saw the bone. This not only brings inconvenience to the use, but also increases the pain of the patient. . [0003] Clinically, in order to ensure the smooth operation and success of the operation, it is necessary to formulate the operation plan and select the relevant surgical instruments. Before the operation, the instruments required for the entire operation process should be properly prepared. For orthopedic surgery, due to the complexity and var...
