Interventional sheath and endoscope

Abstract

This invention discloses an interventional sheath and endoscope. The interventional sheath includes an interventional sheath body, an imaging device, and a sleeve. The interventional sheath body is laterally deformable; the imaging device includes a mounting base and an imaging module; the sleeve is movably and adjustablely fitted onto the interventional sheath body in the front-to-back direction; the sleeve has a higher hardness than the interventional sheath body. This invention allows the sleeve to be fully fitted onto the interventional sheath body by adjusting its forward movement relative to the interventional sheath body until it is close to the mounting base. The greater hardness of the sleeve helps to appropriately enhance the overall hardness of the sheath in its current state, facilitating deeper exploration after the sheath reaches its limit position. Conversely, by adjusting the sleeve to move backward relative to the interventional sheath body away from the mounting base, the interventional sheath body is directly exposed. The flexibility of the interventional sheath body itself helps to appropriately enhance the overall flexibility of the sheath in its current state, facilitating lateral deformation of the sheath according to the airway environment.
