Moisture-detecting shaft for use with an electro-mechanical surgical device
View Patent ↗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.
1. A coupling mechanism, comprising:
an engagement shaft having grooves; and
a clip having flanges, the clip configured to secure the engagement shaft in a hollow shaft of one of a flexible shaft and a surgical attachment;
wherein the clip is configured to be received in the hollow shaft, the flanges of the clip being received in longitudinal slits of the hollow shaft, and wherein the engagement shaft is configured to be received in the clip when the clip is received in the hollow shaft, the clip engaging the grooves of the engagement shaft.
2. A coupling mechanism, comprising:
a hollow shaft having longitudinal slits; and
a clip having flanges, the clip disposed in the hollow shaft, the flanges engaging in the longitudinal slits, the clip configured to receive and secure an engagement shaft of one of a flexible shaft and a surgical instrument in the hollow shaft, wherein the clip is configured to engage grooves of the engagement shaft when the engagement shaft is received in the clip.
