Surgical device with dual cutting and service features
A surgical device may include a housing configured for handling by a user and comprising a plurality of operator interfacing features. The device may also include a patient interfacing tip arranged at, or spaced apart from, a distal end of the housing and controllable by the operator interfacing features. The patient interfacing tip may include a pair of jaws configured to grasp tissue, an electrode on each jaw configured to seal tissue, and an articulating blade configured to cut tissue in a grasp of the pair of jaws. The device may also include an optical element extending from the housing to the patient interfacing tip and configured to emit laser energy to cut tissue, wherein the pair of jaws, electrode, and articulating blade are adapted for coarse cutting of tissue and the optical element is configured for precise cutting of tissue.
1 . A surgical device, comprising:
a housing configured for handling by a user and comprising a plurality of operator interfacing features;
a patient interfacing tip arranged at, or spaced apart from, a distal end of the housing and controllable by the operator interfacing features, the patient interfacing tip comprising a pair of jaws configured to grasp tissue, an electrode on each jaw configured to seal tissue, and an articulating blade configured to cut tissue in a grasp of the pair of jaws;
an optical element extending from a laser source connecting end at or near the housing to the patient interfacing tip and configured to emit laser energy to cut tissue, the optical element being arranged in a working channel extending through a jaw of the pair of jaws to an orifice at a distal end of the jaw; and
an active service element secured to the patient interfacing tip and being operable through a grasping operation of the pair of jaws to pass laterally across and wipe a distal facing tip of the optical element extending out of the distal end of the jaw,
wherein the pair of jaws and the articulating blade are adapted for coarse cutting of tissue and the optical element is configured for precise cutting of tissue.
2 . The device of claim 1 , wherein the optical element is moveable within the working channel.
3 . The device of claim 1 , wherein the optical element is fixed in the working channel.
4 . The device of claim 1 , wherein the active service element comprises a laterally extending element arranged on a first jaw of the pair of jaws and further arranged to pass across a distal end of a second jaw of the pair of jaws, where the working channel and optical element are arranged in the second jaw.
5 . The device of claim 1 , wherein the active service element comprises a frame with a moveable portion that passes across the end of the optical element when the pair of jaws open and close.
6 . A surgical device, comprising:
a housing configured for handling by a user and comprising a plurality of operator interfacing features;
a patient interfacing tip arranged at, or spaced apart from, a distal end of the housing and controllable by the operator interfacing features, the patient interfacing tip comprising a pair of jaws configured to grasp tissue, an electrode on each jaw configured to seal tissue, and an articulating blade configured to cut tissue in a grasp of the pair of jaws;
an optical element extending from a laser source connecting end at or near the housing to the patient interfacing tip and configured to emit laser energy to cut tissue, the optical element being arranged in a working channel extending through a jaw of the pair of jaws to an orifice at a distal end of the jaw; and
an active service element secured to the patient interfacing tip and being operable through a grasping operation of the pair of jaws to wipe a distal tip of the optical element extending out of the distal end of the jaw,
wherein:
the pair of jaws and the articulating blade are adapted for coarse cutting of tissue and the optical element is configured for precise cutting of tissue; and
the active service element comprises a laterally extending element arranged on a first jaw of the pair of jaws and further arranged to pass across a distal end of a second jaw of the pair of jaws, where the working channel and optical element are arranged in the second jaw.
