Abstract

The invention discloses a saw blade for orthopedic surgery which is easy to replace the cutter head, which comprises a gripping rod, a rotating mechanism, a moving mechanism, a cutter head, a stud, a positioning hole, an escape hole, a pressing mechanism, a bolt and a mounting hole, which is convenient for replacement. A saw blade for orthopedic surgery with a cutter head combines a large number of different types of cutter heads into one device, so that the medical staff can quickly and conveniently remove the cutter head to be used from the device. It can be seen that by using the present application The device in the device not only ensures the convenience of medical staff to use any cutter head, but also saves the use space of the operating table, thereby improving the convenience for medical staff to use other surgical instruments on the operating table.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a saw blade for orthopaedic surgery which is convenient to replace the blade head. Background technique [0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. [0003] The saw blade is one of the commonly used medical tools in orthopedic surgery. At present, the traditional saw blade is only equipped with one blade head. During the operation, medical staff need to use different types of blade heads to perform surgery on patients, resulting in the placement of a large number of saw blades. On the operating table, the space occupied by the operating table affects the convenience for medical staff to place other surgical instruments on the operating t...
