Abstract

Abstract An endoscope, comprising an elongated tubular shaft for introducing into a body of a patient, the shaft having a longitudinal axis and a distal end, and further having an opening the distal end. A light guide is arranged along the shaft and has a light-emitting distal end, the light-emitting distal end being arranged in the area of the opening of the shaft in order to radiate light from the opening.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 136 words
An endoscope, comprising an elongated tubular shaft for introducing into a body of a patient, said shaft having a longitudinal axis and a distal end, and further having an opening at said distal end, said opening having a proximal end and a distal end and said opening of said shaft extending obliquely relative to said longitudinal axis of said shaft, a light guide arranged along said shaft and having a light-emitting distal end, said light-emitting distal end being arranged closer to said proximal end of said opening than said distal end of said opening in order to radiate light from a proximal area of said opening, said light-emitting distal end of said light guide being angled relative to said longitudinal axis of said shaft by an angle in a range of about 70° to about 110°.
Claim 2
Dependent Claim 136 words
An endoscope, comprising an elongated tubular shaft for introducing into a body of a patient, said shaft having a longitudinal axis and a distal end, and further having an opening at said distal end, said opening having a proximal end and a distal end and said opening of said shaft extending obliquely relative to said longitudinal axis of said shaft, a light guide arranged along said shaft and having a light-emitting distal end, said light-emitting distal end being arranged closer to said proximal end of said opening than said distal end of said opening in order to radiate light from a proximal area of said opening, said light-emitting distal end of said light guide being angled relative to said longitudinal axis of said shaft by an angle in a range of about 70° to about 110°.
Claim 3
Dependent Claim 44 words
The endoscope of claim 1 , wherein said light-emitting distal end of said light guide comprises a light-emitting window which extends approximately parallel to said longitudinal axis of said shaft when said light guide is oriented parallel to said longitudinal axis of said shaft.
Claim 4
Dependent Claim 37 words
The endoscope of claim 1 , wherein said light-emitting distal end of said light guide is angled relative to said longitudinal axis of said shaft by an angle in a range of about 80° to about 100°.
Claim 5
Dependent Claim 31 words
The endoscope of claim 1 , wherein said light-emitting distal end of said light guide is angled relative to said longitudinal axis of said shaft by an angle of about 90°.
Claim 6
Dependent Claim 30 words
The endoscope of claim 1 wherein an edge of said opening forms, with said longitudinal axis of said shaft, an angle in a range of about 10° to about 40°.
Claim 7
Dependent Claim 31 words
The endoscope of claim 5 , wherein said edge of said opening forms, with said longitudinal axis of said shaft, an angle in a range of about 15° to about 25°.
Claim 8
Dependent Claim 39 words
The endoscope of claim 1 , wherein said light guide can be arranged in an interior of said shaft, and wherein said light guide extends near a shaft wall of said shaft which is directed away from said opening.
Claim 9
Dependent Claim 27 words
The endoscope of claim 1 , wherein said light-emitting distal end of said light guide has such a length that it does not protrude from said opening.
Claim 10
Dependent Claim 16 words
The endoscope of claim 1 , wherein said light guide can be withdrawn from said shaft.
Claim 11
Dependent Claim 52 words
The endoscope of claim 1 , wherein a coupling is present at a proximal end of said light guide and at a proximal end of said shaft for the purpose of securing said light guide on said shaft in a predetermined position of rotation of said light guide relative to said shaft.
Claim 12
Dependent Claim 35 words
The endoscope of claim 1 , used in a tracheotomy, wherein said opening of said shaft is sized to form a protective surface, which prevents a trocar from piercing the posterior wall of the trachea.
Claim 13
Dependent Claim 127 words
An endoscope, comprising an elongated tubular shaft for introducing into a body of a patient, said shaft having a longitudinal axis and a distal end, and further having an opening at said distal end, said opening having a proximal end and a distal end and said opening of said shaft extending obliquely relative to said longitudinal axis of said shaft, said opening forming an angle in a range of about 10° to about 40° with said longitudinal axis of said shaft, a light guide arranged along said shaft and having a light-emitting distal end, said light-emitting distal end being arranged closer to said proximal end of said opening than said distal end of said opening in order to radiate light from a proximal area of said opening.
Claim 14
Dependent Claim 127 words
An endoscope, comprising an elongated tubular shaft for introducing into a body of a patient, said shaft having a longitudinal axis and a distal end, and further having an opening at said distal end, said opening having a proximal end and a distal end and said opening of said shaft extending obliquely relative to said longitudinal axis of said shaft, said opening forming an angle in a range of about 10° to about 40° with said longitudinal axis of said shaft, a light guide arranged along said shaft and having a light-emitting distal end, said light-emitting distal end being arranged closer to said proximal end of said opening than said distal end of said opening in order to radiate light from a proximal area of said opening.
Claim 15
Dependent Claim 31 words
The endoscope of claim 12 , wherein said edge of said opening forms, with said longitudinal axis of said shaft, an angle in a range of about 15° to about 25°.
Claim 16
Dependent Claim 44 words
The endoscope of claim 12 , wherein said light-emitting distal end of said light guide comprises a light-emitting window which extends approximately parallel to said longitudinal axis of said shaft when said light guide is oriented parallel to said longitudinal axis of said shaft.
Claim 17
Dependent Claim 39 words
The endoscope of claim 12 , wherein said light guide can be arranged in an interior of said shaft, and wherein said light guide extends near a shaft wall of said shaft which is directed away from said opening.
Claim 18
Dependent Claim 27 words
The endoscope of claim 12 , wherein said light-emitting distal end of said light guide has such a length that it does not protrude from said opening.
Claim 19
Dependent Claim 35 words
The endoscope of claim 12 , used in a tracheotomy, wherein said opening of said shaft is sized to form a protective surface, which prevents a trocar from piercing the posterior wall of the trachea.
