Abstract
Abstract Grasping an object, e.g., a calculus in the biliary tract, using a grasper, such as a basket, that can be opened and closed without mechanical advantage and also rotated about the device axis to make it easier to capture the object. The basket can then be closed further with mechanical advantage to crush the object.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
79 words
An operating handle for a medical instrument, comprising: a housing, a control element extending along an axis, a manual actuator directly connected to said control element for moving said control element axially and for rotating said control element about the axis relative to said housing to a desired orientation, and a mechanical actuator coupled to said control element, said mechanical actuator being actuatable to move said control element axially with mechanical advantage and without rotation from said desired orientation.
Claim 2
Dependent Claim
79 words
An operating handle for a medical instrument, comprising: a housing, a control element extending along an axis, a manual actuator directly connected to said control element for moving said control element axially and for rotating said control element about the axis relative to said housing to a desired orientation, and a mechanical actuator coupled to said control element, said mechanical actuator being actuatable to move said control element axially with mechanical advantage and without rotation from said desired orientation.
Claim 3
Dependent Claim
20 words
The handle of claim 1 wherein said control element is adapted for being extended and withdrawn relative to a sheath.
Claim 4
Independent Claim
103 words
A method of grasping an object in the body, comprising: providing a medical instrument having an instrument axis and including a grasper actuatable between an open and closed condition, said medical instrument including a housing and an operating mechanism for actuating said grasper alternatively with mechanical advantage or without mechanical advantage and for rotating said grasper about said axis relative to said housing, positioning said grasper in proximity to said object, actuating said grasper to open said grasper, rotating said grasper to a desired orientation and manipulating said grasper about said object, and actuating said grasper with mechanical advantage to close said grasper.
Claim 5
Independent Claim
103 words
A method of grasping an object in the body, comprising: providing a medical instrument having an instrument axis and including a grasper actuatable between an open and closed condition, said medical instrument including a housing and an operating mechanism for actuating said grasper alternatively with mechanical advantage or without mechanical advantage and for rotating said grasper about said axis relative to said housing, positioning said grasper in proximity to said object, actuating said grasper to open said grasper, rotating said grasper to a desired orientation and manipulating said grasper about said object, and actuating said grasper with mechanical advantage to close said grasper.
Claim 6
Dependent Claim
21 words
The method of claim 3 comprising actuating said grasper with mechanical advantage without rotation of said grasper from said desired orientation.
Claim 7
Dependent Claim
14 words
The method of claim 3 or 4 comprising delivering said instrument through an endoscope.
