Couplings for interconnecting components of an electro-mechanical surgical device

摘要

A flexible shaft includes a flexible, elongated outer sheath, at least one drive shaft disposed within the outer sheath and a moisture sensor disposed within the outer sheath configured to detect moisture within the outer sheath. Another flexible shaft includes a flexible, elongated outer sheath, at least one flexible drive shaft disposed within the outer sheath and a coupling connected to a distal end of the outer sheath configured to couple to a surgical attachment.;A sleeve includes an elongated shaft configured to receive a flexible shaft therein and a securing arrangement configured to selectively and variably retain the elongated shaft in any one of a number of longitudinal positions along the flexible shaft.;A surgical system includes an electro-mechanical driver, an elongated, flexible sheath, at least one drive shaft disposed within the flexible sheath, a surgical attachment coupled to the at least one drive shaft, the electro-mechanical driver configured to drive the surgical attachment, a shape-retaining sleeve, at least a portion of the flexible sleeve being disposed in the shape-retaining sleeve, the shape-retaining sleeve configured to maintain the at least portion of the flexible sheath in a predetermined shape, and an arrangement variably securing the shape-retaining member to the flexible sheath in any one of a number of longitudinal positions along the flexible sheath.

主权项

1. A coupling, comprising:
a distal cover; a link having a proximal end and a distal end, the proximal end being configured for attachment to a shaft of an electro-mechanical surgical device and the distal end being configured to be selectively detachably connected to the distal cover to form a fluid-tight and air-tight seal therebetween; a flexible strip locking mechanism for detachably coupling the distal cover to the distal end of the link, wherein the distal cover defines a first annular recess and the link defines a second annular recess such that upon connecting the distal cover and the link, the first annular recess and the second annular recess together form an annular cavity having the flexible strip locking mechanism removably disposed therein; a rotatable shaft engagement member configured to engage a rotatable drive shaft, at least a portion of the rotatable shaft engagement member being disposed in the distal cover; and a moisture sensor disposed in the distal cover configured to sense moisture in the distal cover.
