Abstract
Apparatus for sheathing an endoscopic tool is described. The apparatus is suitable for sheathing the tool when it is displaced in a proximal direction from a working channel of an endoscope. The apparatus comprises a sheathing assembly, which is attachable to a proximal port of the endoscope and to the endoscopic tool. Within the sheathing assembly is deployed a folded, flexible sleeve adapted to unfold from the assembly when the tool is retracted in the proximal direction from the working channel. The sheathing assembly is designed to allow displacement of the tool through the sheathing assembly in a distal direction and simultaneous retraction of the tool together with the sheathing assembly in the proximal direction.
Claims20
A combination of a sheathing assembly and an endoscopic tool for sheathing the endoscopic tool, said sheathing assembly being attachable to a proximal port of the endoscope and to the endoscopic tool, said sheathing assembly accommodating therein a folded, flexible sleeve unfolding from the assembly to sheath the endoscopic tool as it is being retracted, wherein said combination allows displacement of the endoscopic tool through the sheathing assembly in a distal direction and simultaneous retraction of the endoscopic tool together with the sheathing assembly in a proximal direction.
An apparatus for sheathing an endoscopic tool when it is displaced in a proximal direction, said apparatus comprising:
- a sheathing assembly attachable to the endoscopic tool, and said sheathing assembly having means for allowing displacement of the endoscopic tool through the sheathing assembly in a distal direction and simultaneous retraction of the endoscopic tool together with the sheathing assembly when the endoscopic tool is being displaced in the proximal direction;
- and
- a folded, flexible sleeve deployed in the sheathing assembly and unfolding from the assembly to sheath the endoscopic tool as it is being retracted in the proximal direction from the working channel.
A method for sheathing an endoscopic tool when it is displaced in a proximal direction, said method comprises:
- attaching a frontal portion of a sheathing assembly to a proximal port of the endoscope, said sheathing assembly accommodating therein a folded, flexible sleeve unfolding from the assembly to sheath the endoscopic tool as it is being retracted from the working channel,
- securing a rear, sleeve dispenser portion of the sheathing assembly on a shaft of the endoscopic tool,
- disconnecting of the rear portion from the frontal portion;
- and
- simultaneous retraction of the endoscopic tool together with the rear portion of the sheathing assembly in the proximal direction.
