Abstract
Abstract An endoscope has a passage (8) through which passes a shaft (4) of an auxiliary instrument such as a probe, forceps or bundle of glass fibres. The auxiliary instrument has an angularly movable leading end portion (2) connected to the shaft (4) by a flexible intermediate portion (3). The angular position of the leading end portion (2) can be adjusted by axial movement of the shaft (4), causing the end portion (2) to abut against stops which are advantageously formed by leading end portions of the endoscope passage (8). The end portion (2) is preferably biased into an angular position transverse to the shaft (4), so that pulling on the shaft tends to straighten the leading end (2). The auxiliary instrument is preferably rotatable about the longitudinal axis of the shaft (4), so that the leading end (2) can be moved into any desired position. <IMAGE>

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
An endoscope having an optical system and a longitudinal passage through which passes a shaft of an auxiliary instrument, wherein said instrument shaft has an angled distal end portion projecting from the passage and includes at least a resiliently flexible angled portion which can be urged into sliding abutting relationship with the distal end of said passage in such a way that the angular position of the distal end portion of the shaft can be adjusted by axial movement of said shaft in the endoscope passage.
Claim 2
Dependent Claim
86 words
An endoscope having an optical system and a longitudinal passage through which passes a shaft of an auxiliary instrument, wherein said instrument shaft has an angled distal end portion projecting from the passage and includes at least a resiliently flexible angled portion which can be urged into sliding abutting relationship with the distal end of said passage in such a way that the angular position of the distal end portion of the shaft can be adjusted by axial movement of said shaft in the endoscope passage.
Claim 3
Dependent Claim
26 words
An endoscope according to claim 1, wherein the distal end portion of the auxilary instrument is spring biassed towards an angular position transverse to the shaft.
Claim 4
Dependent Claim
70 words
An endoscope according to claim 2, wherein the said flexible angled portion of the auxiliary instrument is arranged to abut a leading edge of the endoscope passage on one side thereof and an inside wall of said passage on the opposite side, whereby drawing the shaft axially through the passage in a proximal direction causes the distal end portion to move from a radially extending position to an axially-extending position.
Claim 5
Dependent Claim
21 words
An endoscope according to any preceding claim wherein the shaft and the distal end portion of the auxiliary instrument are flexible.
Claim 6
Dependent Claim
17 words
An endoscope according to any preceding claim, wherein the auxiliary instrument is rotatable about its shaft axis.
Claim 7
Dependent Claim
16 words
An endoscope substantially as herein described with reference to, and as illustrated in, the accompanying drawings.
Claim 8
Dependent Claim
16 words
An endoscope substantially as herein described with reference to, and as illustrated in, the accompanying drawings.
Claim 9
Dependent Claim
78 words
An auxiliary instrument for an endoscope comprising an elongate shaft to enable the instrument to pass through an endoscope passage and a leading end portion attached to one end of the shaft, said end portion being biassed to an angular position transverse to the axis of the shaft and being attached to the shaft by a flexible connection portion to enable the angular position of the end portion to be adjusted by cooperation with parts of the endoscope.
Claim 10
Dependent Claim
78 words
An auxiliary instrument for an endoscope comprising an elongate shaft to enable the instrument to pass through an endoscope passage and a leading end portion attached to one end of the shaft, said end portion being biassed to an angular position transverse to the axis of the shaft and being attached to the shaft by a flexible connection portion to enable the angular position of the end portion to be adjusted by cooperation with parts of the endoscope.
