Abstract
Abstract A surgical instrument comprises a handle, an electrical cauterization electrode, a mounting for movably joining the electrode to the handle so that distance of the electrode from the handle may be adjusted prior to a surgical procedure, and an electrical supply mechanically connected to the handle and operatively connected to the electrode for supplying thereto an electrical voltage having a characteristic waveform.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
84 words
A surgical instrument comprising: a handle; an electrical cauterization electrode movably mounted to said handle so that distance of said electrode from said handle may be adjusted prior to a surgical procedure, said electrode taking the form of a telescoping rod having a plurality of segments slidably mounted with respect to each other and with respect to said handle; and electrical supply means mechanically connected to said handle and operatively connected to said electrode for supplying thereto an electrical voltage having a characteristic waveform.
Claim 2
Dependent Claim
84 words
A surgical instrument comprising: a handle; an electrical cauterization electrode movably mounted to said handle so that distance of said electrode from said handle may be adjusted prior to a surgical procedure, said electrode taking the form of a telescoping rod having a plurality of segments slidably mounted with respect to each other and with respect to said handle; and electrical supply means mechanically connected to said handle and operatively connected to said electrode for supplying thereto an electrical voltage having a characteristic waveform.
Claim 3
Independent Claim
110 words
A method for use in performing a surgical operation, comprising the steps of: providing an electrical cauterization instrument having a handle and a cauterization electrode mounted to said handle, said electrode taking the form of a telescoping rod; moving said electrode relative to said handle to adjust the distance of an operative tip of said electrode from said handle, said step of moving including the step of at least partially collapsing said rod; engaging organic tissues with said operative tip; and during said step of engaging, supplying to said electrode an electrical voltage having a characteristic waveform, thereby effectuating a cauterization of the organic tissues engaged by said operative tip.
Claim 4
Independent Claim
110 words
A method for use in performing a surgical operation, comprising the steps of: providing an electrical cauterization instrument having a handle and a cauterization electrode mounted to said handle, said electrode taking the form of a telescoping rod; moving said electrode relative to said handle to adjust the distance of an operative tip of said electrode from said handle, said step of moving including the step of at least partially collapsing said rod; engaging organic tissues with said operative tip; and during said step of engaging, supplying to said electrode an electrical voltage having a characteristic waveform, thereby effectuating a cauterization of the organic tissues engaged by said operative tip.
Claim 5
Dependent Claim
29 words
The method defined in claim 2, further comprising the step of inserting said electrode through a small opening in a patient, said organic tissues being located inside the patient.
Claim 6
Dependent Claim
69 words
The method defined in claim 3, further comprising the steps of removing said electrode from the patient, again moving said electrode relative to said handle to readjust the distance of said operative tip from said handle, again inserting said electrode through a small opening in a patient, subsequently engaging different organic tissues with said operative tip, and during said step of subsequently engaging, supplying electrical current to said electrode.
Claim 7
Independent Claim
110 words
A method for use in performing a surgical operation, comprising the steps of: providing an electrical cauterization instrument having a handle and a cauterization electrode mounted to said handle, said electrode taking the form of a telescoping rod; moving said electrode relative to said handle to adjust the distance of an operative tip of said electrode from said handle, said step of moving including the step of at least partially extending said rod; engaging organic tissues with said operative tip; and during said step of engaging, supplying to said electrode an electrical voltage having a characteristic waveform, thereby effectuating a cauterization of the organic tissues engaged by said operative tip.
Claim 8
Independent Claim
110 words
A method for use in performing a surgical operation, comprising the steps of: providing an electrical cauterization instrument having a handle and a cauterization electrode mounted to said handle, said electrode taking the form of a telescoping rod; moving said electrode relative to said handle to adjust the distance of an operative tip of said electrode from said handle, said step of moving including the step of at least partially extending said rod; engaging organic tissues with said operative tip; and during said step of engaging, supplying to said electrode an electrical voltage having a characteristic waveform, thereby effectuating a cauterization of the organic tissues engaged by said operative tip.
Claim 9
Dependent Claim
29 words
The method defined in claim 5, further comprising the step of inserting said electrode through a small opening in a patient, said organic tissues being located inside the patient.
Claim 10
Dependent Claim
69 words
The method defined in claim 6, further comprising the steps of removing said electrode from the patient, again moving said electrode relative to said handle to readjust the distance of said operative tip from said handle, again inserting said electrode through a small opening in a patient, subsequently engaging different organic tissues with said operative tip, and during said step of subsequently engaging, supplying electrical current to said electrode.
