INTERVENTION INSTRUMENT RELEASE CONTROL MECHANISM, RELEASE METHOD, AND INTERVENTION INSTRUMENT DELIVERY SYSTEM

摘要

An intervention instrument release control mechanism, a release method, and an intervention instrument delivery system. The intervention instrument release control mechanism comprises a first tube (11), a middle tube (13), and a second tube (12) which are fitted from the inside to the outside in a sliding manner, the distal end of the first tube (11) extends out of the middle tube (13), and a mounting head (112) for connecting with an intervention instrument is provided on the extended out portion; a flexible control member is connected to the middle tube (13); the control member has a holding state in which the control member passes through the mounting head (112) and constrains the intervention instrument to the mounting head (112), and an open state in which the intervention instrument is allowed to be completely disengaged from the mounting head (112); the middle tube (13) is provided with a lock member (162) fitted with the control member, and the lock member (162) is in sliding fit with respect to the middle tube (13) and switches the different states of the control member when sliding. For an intervention instrument delivery system, the release manner of an intervention instrument is improved, allowing more convenient operation.
