Abstract
An endoscopic surgical instrument for removing tissue or bone, the instrument comprising (1) a generally tubular component (2) a cutting device which is housed in the distal end member and part of which protrudes beyond the window in the distal member, and (3) a means for operating the cutting device. The tubular component comprises a distal end member containing a cutting device, a proximal member, and between the distal member and the proximal member a hollow, generally tubular intermediate member which deforms elastically when the angle between the distal member family proximal member is changed. The intermediate member can for example be composed of a nickel titanium alloy, and/or can be slotted, and/or can be in the form of an accordion, and/or be in the form of a coil
Claims3
A generally tubular component which comprises
- (1) a hollow, generally tubular distal end member which (a) has a first distal axis, (b) is rigid, and (c) comprises a window which exposes a substantial part of the interior of the distal end member, and
- (2) a proximal member which (a) is rigid, and (b) comprises a first proximal section which is adjacent to the distal end member and which has a first proximal axis which is usually the same as the first distal axis but can be different from the first distal axis, and
- (3) between the distal end member and the proximal member, a hollow, generally tubular intermediate member which deforms elastically when the angle between the first distal axis and the first proximal axis is changed.
