Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a shielding plate used in joint replacement surgery. Background Art

[0002] Joint replacement surgery is an effective treatment for end-stage joint injuries. During joint replacement surgery, an electric oscillating saw is used to amputate the original damaged joint, and a clamping tool is used to clamp the artificial joint into place. Then, a hammer is used to repeatedly hit the clamping tool to press the artificial joint tightly. During the entire operation, with the swing of the electric oscillating saw and the hitting of the hammer, the bone chips in the wound and the blood oozing from the bone surface will be scattered irregularly in all directions. Some bone chips will hit the operator and then rebound to the surgical field, contaminating the wound and increasing the incidence of surgical infection; some blood will splash onto the operator's face and even into the eyes, resulting in occupational exposure.

[0003] The currently used occlusion tools have the following disadvantages. First, they are made of rigid materials and their shapes cannot be changed. During use, the fixed-shape occlusion tools cannot completely cover the wound surface, and blood or bone chips will still fly out of the wound. Second, there is no oleophobic coating. During use, oil-rich blood and bone chips will adhere to the surface of the occlusion tool. Even if it is immediately washed with sterile water or wiped with wet gauze, the occlusion tool will still be blurred, blocking the field of vision and affecting the surgical operation. Third, the currently used occlusion tools need to be handheld, which requires additional surgical personnel. Utility Model Content
