Surgical Devices

摘要

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

1. 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.
