Abstract
A device and method for extracting tubular structures are provided. An incision is made at a proximate and at a distal end of a tubular structure. An extracting device is inserted into and passed through a tubular structure until the operational head of the device extends past the distal incision. An actuator on the handle of the device is actuated, longitudinally extending the operational head of the device. The edge of a tubular structure is positioned axially in the mouth of a hook wire on the operational head. The actuator on the handle is released and the hook wire engages and captures the tubular structure. The user manually pulls the tubular structure, invaginating and removing it.
Claims30
A device for extracting a tubular structure from tissue, the device comprising:
- a handle having an actuator;
- an elongate body with a first end coupled to and extending from the handle, the elongate body having a channel extending therethrough;
- and
- an operational head disposed at a second end of the elongate body, the operational head being longitudinally movable between a neutral position and an actuated position;
- wherein the actuator is operatively coupled to the operational head and configured to actuate longitudinal movement of the operational head relative to the second end of the elongate body.
A device for removing a blood vessel from a tissue, the device comprising:
- a shaft having a proximal end and a distal end;
- a handle operatively coupled to the proximal end of the shaft, the handle including an actuator;
- and
- an operational head disposed at the distal end of the shaft, the operational head being operatively coupled to the actuator and configured for forward movement relative to the distal end of the shaft upon actuation of the actuator.
A method for removing a blood vessel from a tissue, the method comprising:
- exposing and cutting a proximal end of the blood vessel;
- exposing and cutting a distal end of the blood vessel;
- inserting an extraction device into the proximal end of the blood vessel, the extraction device having:
- a shaft having a proximal end and a distal end;
- a handle operatively coupled to the proximal end of the shaft, the handle including an actuator;
- and
- an operational head disposed at the distal end of the shaft, the operational head including a hook member operatively coupled to the actuator and configured for forward movement relative to the distal end of the shaft upon actuation of the actuator;
- positioning the extraction device such that the operational head is proximate the distal end of the blood vessel;
- actuating the actuator to extend the operational head forward without extending the operational head laterally or radially outward;
- engaging and securing the distal end of the blood vessel;
- and
- removing the extraction device to remove the blood vessel.
