摘要： A medical instrument including a resiliently flexible first elongate member and a resiliently flexible second elongate member. The first elongate member has a first proximal end portion and a first distal portion. The second elongate member has a second proximal end portion and a second distal portion, wherein the second distal portion is attached to the first distal portion, and wherein the attached first and second distal portions define a distal-loop medical snare which is insertable within a patient. In a first example, the first proximal end portion is lengthwise translatable with respect to the second proximal end portion to articulate the medical snare. In the same or a second example, the first proximal end portion is rotatable about its centerline to articulate the medical snare.

摘要： Disclosed herein are devices and methods for forming multidirectional cuts in tissue. The tissue cutting devices disclosed herein generally include a flexible elongate member with at least first, second, and third wires that are at least partially constrained within or along a portion of the member. A distal portion of the wires is anchored on or within a portion of the elongate member. When tension is applied to at least one of the wires, such as by an actuator at a proximal end of the device, the elongate member bows while an unconstrained portion of the wire becomes exposed relative to the adjacent portion of the elongate member, assuming a tissue-cutting configuration.

摘要： A medical instrument includes a flexible tube, a distal member, a flexible end-effector activation wire, a proximal member, and a flexible first cable. The distal member is connected to the distal tube portion. The activation wire is positioned within the tube. The proximal member is attached to the tube. The first cable is positioned outside the tube, is substantially transversely constrained by the proximal member, and has a first distal cable portion attached to the distal member. Lengthwise translation of the first cable articulates the distal member with respect to the proximal member. Another instrument includes a drive screw which articulates an end effector (e.g., a grasper) pivotally connected to a tube. An additional instrument includes a drive screw which articulates a distal medical instrument member pivotally connected to a tube. A medical end effector (e.g., a snare) is positionable in a lumen of the distal medical instrument member.

The four medical coilpipes include a central coilpipe and three peripheral coilpipes disposed outward of the central coilpipe. The four medical coilpipes are wound from a continuous length of wire. In one example, a lengthwise translatable medical-end-effector activation cable is located in the central coilpipe, a separate and lengthwise translatable medical-instrument-member articulation cable is located in each of the three peripheral coilpipes, and the distal end portion is endoscopically insertable into the patient. Other examples are left to those skilled in the art.

摘要： A medical instrument handle includes a stem, a joystick assembly, and a medical-instrument-member first articulation cable. The stem has a proximal stem portion and a distal stem portion. The joystick assembly includes a platform, a proximal joystick portion and a distal joystick portion, wherein the distal joystick portion is articulatably connected to the proximal stem portion. The first articulation cable includes a proximal cable portion which is connected to the platform and which is substantially transversely constrained by the stem. Articulation of the joystick assembly with respect to the stem changes a distance between the platform and the stem as measured along the first articulation cable. A medical instrument includes a medical instrument handle and a medical end effector. Examples of medical end effectors include, without limitation, a medical grasper and a medical snare.
