Abstract
A distal end structure of an endoscope according to the present invention includes a distal end member formed of a metal material, an insulating ring provided in an annular shape around an insertion axis on a proximal end side of the distal end member, a cover formed of a flexible insulative material that covers the distal end member, a projecting section provided integrally with the insulating ring and projecting in a direction crossing the insertion axis, a through-hole provided in the cover and engaging with the projecting section, and a to-be-tom-apart section provided near the through-hole, in which force is applied to the to-be-torn-apart section to tear apart the cover along the insertion axis direction and remove the cover from the distal end member.
Claims12
A distal end structure of an endoscope formed to extend along an insertion axis, the distal end structure of the endoscope comprising:
- a distal end member formed of a metal material;
- an insulating member provided around the insertion axis on a proximal end side of the distal end member;
- a cover formed of a flexible insulative material that covers the distal end member;
- a projecting section provided integrally with the insulating member and projecting in a direction crossing the insertion axis;
- an opening window provided in the cover to expose a part of the distal end member;
- a through-hole provided between the opening window in the cover and a proximal end portion of the cover and engaging with the projecting section;
- and
- a to-be-torn-apart section provided on both width direction sides of the through-hole in the cover to linearly extend from a proximal end portion of the opening window to the proximal end portion of the cover along a direction of the insertion axis passing through a side of the through-hole and torn apart by force from an outside to enable the cover to be removed from the distal end member.
