摘要： A biopsy forceps device includes a control member; a yoke coupled to the member; jaws coupled to the yoke; and a capsule. In an open configuration, the jaws are separated to receive target tissue. In a closed configuration, cutting edges of the jaws are moved toward one another to cut tissue. The capsule slidably receives the yoke and a portion of the jaws. The jaws are constrained to the closed configuration when withdrawn proximally to a first position within the capsule. When the jaws are moved to a second position, portions of the jaws are freed from the constraint capsule and spread apart. When the yoke and the jaws are moved distally and the jaws move to the open configuration, a tissue contacting structure of the yoke extends distally to engage tissue between the jaws to anchor the engaged tissue again lateral movement as the jaws contact the tissue.

摘要： A medical device adaptor may comprise a distal portion, including a cap configured to be removably affixed to a distal end of a medical device and a channel extending through a lumen of the cap. The channel may be in fluid communication with a working channel of the medical device upon removably affixing the cap to the distal end of the medical device. The adaptor may further comprise a proximal portion including an actuator having a lumen. The actuator may be removably affixed to a proximal end of the medical device, such that the lumen of the proximal portion is configured to be in fluid communication with the working channel of the medical device. The medical device adaptor also may include one or more wires extending between the proximal portion and the distal portion. The one or more wires may be configured to articulate the channel of the distal portion.

摘要： A medical device includes a handle, an end cap, and a patch. The handle includes a movable body and a stationary body. The movable body includes an actuation member. The end cap is configured to be coupled to a distal end of a scope. The patch is movable relative to the end cap. The patch is coupled to the movable body via one or more control elements such that movement of the movable body extends the patch from the end cap. The patch is further coupled to the actuation member via one or more actuation elements such that movement of the actuation member extends, bows, or bends the one or more actuation elements to at least partially deploy the patch.

摘要： A medical device may comprise a handle having at least one actuator, a shaft having a proximal end and a distal end, the proximal end connected to the handle, and a distal assembly connected to the distal end of the shaft, the distal assembly including an end effector. The handle may be configured so that a single hand of a user can operate the at least one actuator to (1) actuate the end effector, (2) rotate the end effector relative to the shaft, and (3) articulate a distal portion of the shaft.

摘要： A medical device that includes a handle including a plurality of actuators. The handle defines a longitudinal axis extending through a distal end of the handle. The device includes a shaft extending from the handle and an end effector at a distal end of the shaft. A first actuator of the plurality of actuators is configured to actuate the end effector in response to translation of the first actuator relative to the handle along an axis parallel to the longitudinal axis. A second actuator of the plurality of actuators is configured to deflect the end effector relative to the shaft in response to pivoting the second actuator about an axis transverse to the longitudinal axis. A third actuator of the plurality of actuators is configured to rotate the end effector relative to the shaft in response to rotation of the third actuator relative to the handle about the longitudinal axis.

摘要： A medical assembly that includes a medical device including a handle having an actuator, a shaft extending distally from the handle, and a sensor at a distal end of the shaft. The distal end of the shaft is coupled to the actuator by a wire extending through the shaft, and the sensor is configured to measure data indicative of the distal end of the shaft moving from a first position to a second position. The actuator is configured to articulate the distal end of the shaft based on the data measured by the sensor to move the distal end from the second position to the first position.
