Abstract:
Disclosed is a fully detachable trocar, comprising: a cannula; a support connected to one end of the cannula; a channel passing through the cannula and the support along an axial direction; an air-inflated structure arranged on the support and communicated with the channel; an air valve for controlling the air-inflated structure to turn on and off; a primary sealing component for sealing when a device is used; and a second sealing component for sealing when no device is used; the primary sealing component, the second sealing component and the support are connected in a sealing manner from top to bottom in sequence, and the primary sealing component can be independently separated from the second sealing component which can be independently separated from the support, so as to provide multiple methods for taking out tissues.

Claim (Index 2):
The fully detachable trocar according to  claim 1 , wherein the primary sealing component comprises:\n a primary sealing seat with an axial through hole; a primary sealing membrane fixedly connected at an external edge thereof to the through hole and provided at a center thereof with a round hole, wherein the device can be encircled by the primary sealing membrane when passing through the round hole to form an airtight structure, and a close-fitting with the device can be maintained by the first sealing membrane as the device moves; a plurality of sealing plates uniformly arranged along a periphery of the round hole, with one end being fixedly connected to the primary sealing membrane and the other end extending to a central region of the round hole, wherein neighboring sealing plates are partially overlapped to form a lens-type leaf structure; when the device passes through the round hole, the sealing plates are fit with a periphery of the device to form an airtight structure, and can recover to an initial status quickly after the device is pulled out, so as to adapt to the sealing requirements of instruments with different sizes; and the sealing plates are arranged at either side of the round hole to enable the instrument to keep sealing in the process of inserting in and pulling out.
