23 Jul Minimally invasive collagen membrane retainer used for tissue engineering cartilage grafting
Abstract
A minimally invasive collagen membrane retainer used for tissue engineering cartilage grafting comprises a body, a first clamping arm set, a second clamping arm set and a control mechanism for driving the first clamping arm set and the second clamping arm set to close. The two clamping arms are located at the front end of the body. The control mechanism comprises a sliding assembly and a connection rod assembly which are in driving connection, and the connection rod assembly is connected with the first and second clamping arm sets and used for driving the first clamping arm set to overlap in the extending direction. According to the retainer, the two clamping arm sets are overlapped under the drive of the sliding assembly and the connection rod assembly, a collagen membrane is clamped, the sliding assembly moves to the body and drives the connection mechanism, the connection rod mechanism makes the clamping arm sets extend forward to the body and overlap, and clamping is achieved. Compared with operating forceps and retainers in the prior art, the expanded area is small, surgical wounds are not expanded, and operation is convenient.
