MINIMALLY-INVASIVE COLLAGEN MEMBRANE CLAMPER FOR TISSUE-ENGINEERED CARTILAGE TRANSPLANT

摘要

A minimally-invasive collagen membrane clamper for tissue-engineered cartilage transplant comprises a body (1), a first clamping arm group (2), a second clamping arm group (3), and a control mechanism (4) for driving the first clamping arm group (2) and the second clamping arm group (3) to be closed and opened. The clamping arm groups (2, 3) are located at the front end of the body (1). The control mechanism (4) also comprises a slide assembly and a connection rod assembly. The slide assembly is connected to the connection rod assembly in a driving manner. The connection rod assembly is separately connected to the first clamping arm group (2) and the second clamping arm group (3), and is used for driving the first clamping arm group (2) to coincide along the extension direction. In the clamper, by means of the slide assembly and the connection rod assembly, the clamping arm groups (2, 3) are driven to coincide, so as to clamp a collagen membrane; the slide assembly slides along the direction of the body (1) to drive the connection rod assembly, and the connection rod assembly enables the clamping arm groups (2, 3) to extend forwards along the direction of the body (1) and to coincide, and accordingly clamping is implemented.
