Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
62 words
A method for handling a flexible endoscope comprising the steps of: parameterizing the flexible endoscope according to a plurality of parameters for handling the endoscope given a desired task; determining, pre-operatively, at least one endoscope configuration of the parameters, based on a predetermined patient model; determining instructions for handling the endoscope according to the configuration; handling the endoscope according to the instructions.
Claim 2
Independent Claim
62 words
A method for handling a flexible endoscope comprising the steps of: parameterizing the flexible endoscope according to a plurality of parameters for handling the endoscope given a desired task; determining, pre-operatively, at least one endoscope configuration of the parameters, based on a predetermined patient model; determining instructions for handling the endoscope according to the configuration; handling the endoscope according to the instructions.
Claim 3
Dependent Claim
16 words
The method of claim 1 , further comprising determining a digital model of a flexible endoscope.
Claim 4
Dependent Claim
19 words
The method of claim 1 , further comprising the step of registering a patient to the predetermined patient model.
Claim 5
Dependent Claim
25 words
The method of claim 1 , further comprising the step of identifying a mutual landmark visible in a patient and in the predetermined patient model.
Claim 6
Dependent Claim
16 words
The method of claim 4 , wherein the landmark is a carina of a tracheobronchial tree.
Claim 7
Dependent Claim
18 words
The method of claim 1 , further comprising the step of determining a configuration relative to a landmark.
Claim 8
Dependent Claim
18 words
The method of claim 1 , wherein the step of parameterizing further comprises determining an endoscope length parameter.
Claim 9
Dependent Claim
61 words
The method of claim 7 , further comprising the steps of: inserting the endoscope to a landmark; and inserting the endoscope to a target site, wherein a distance to the target site from the landmark is a difference between a total distance from a reference point to the target site and an intermediate distance from the reference point to the landmark.
Claim 10
Dependent Claim
26 words
The method of claim 1 , wherein the step of parameterizing further comprises the step of determining a shaft-rotation of the endoscope according to a landmark.
Claim 11
Dependent Claim
27 words
The method of claim 9 , wherein determining a shaft-rotation comprises determining an angle between a bending plane of a tip of the endoscope and a target.
Claim 12
Dependent Claim
23 words
The method of claim 1 , wherein the step of parameterizing further comprises the step of determining a bending angle of the endoscope.
Claim 13
Dependent Claim
61 words
The method of claim 11 , wherein determining the bending angle comprises the steps of: approximating a bending movement by a semi-circle with a given center; determining a first vector between the center and a tip of the endoscope; determining a second vector between the center and a target; and determining the angle between the first vector and the second vector.
Claim 14
Dependent Claim
41 words
The method of claim 1 , wherein parameterizing further comprises the steps of: determining a tool length, wherein the tool is coupled to a tip of the endoscope; and determining a distance between the tip of the endoscope and a target.
Claim 15
Dependent Claim
25 words
The method of claim 13 , wherein determining the tool length comprises determining the distance between an aligned tip of the endoscope and a target.
Claim 16
Dependent Claim
28 words
The method of claim 1 , wherein determining instructions for handling the endoscope according to the configuration are determined prior to inserting the flexible endoscope into a patient.
