Abstract: Systems, devices, and methods for determining a distance between a distal end of an endoscope and a target during an endoscopic procedure are disclosed. A surgical laser feedback control system comprises a feedback analyzer and a controller. The feedback analyzer can receive at least two reflected signals from a target in response to electromagnetic radiation directed at the target. The at least two reflected signals correspond to respective different distances between a distal end of a device of a surgical laser system and the target. The feedback analyzer can determine a distance between the distal end of the device of the surgical laser system and the target based on the at least two reflected signals. The controller can generate a control signal to the surgical laser system to perform a predetermined operation based on the determined distance.

Abstract: A lithotripsy or other medical laser treatment system can include a lateral actuator to laterally displace a distal portion of a laser fiber, such as can be scanned or otherwise controlled to generate a spatial or spatiotemporal sub-targeting pattern without requiring laterally moving an endoscope carrying the laser fiber in a longitudinal passage such as a working channel. A targeted stone can be selectively weakened along the pattern, such as using lower energy pulses, before being fragmented, such as by a higher energy shock pulse.

Abstract: A surgical tool can include a handle, an outer tube, an end effector, an inner tube, and a guide tube. The outer tube can be connected to the handle and can extend along a longitudinal axis. The end effector can be connected to the outer tube. The inner shaft can be located within the outer tube and can extend along the longitudinal axis. The inner shaft can be connected to the end effector and the outer shaft. The handle can be operable to translate the inner shaft with respect to the outer tube to operate the end effector. The guide tube can be located within the outer tube between the handle and the end effector. The guide tube can include a conduit extending therethrough.

Abstract: A forceps having an outer tube extending from a proximal portion to a distal portion and defining a longitudinal axis. A reciprocating inner tube can be located within the outer tube and extend along the longitudinal axis. A stationary jaw can be coupled to the distal portion of the outer tube and a moving jaw can be pivotably moveable relative to the stationary jaw. The moving jaw can be engaged with a portion of the reciprocating inner tube such that translation of the reciprocating inner tube pivots the moving jaw relative to the stationary jaw between an open and closed position.

Abstract: An apparatus includes a sheath configured to be at least partially inserted into a body of a patient, the sheath having a distal end and a proximal end; a housing coupled to the proximal end of the sheath; and a control mechanism operably coupled to the housing and slidable to move the sheath relative to the housing. The control mechanism includes a locking mechanism for locking the control mechanism in place relative to the housing; a deflection mechanism for articulating a distal end of the sheath; and a saddle slidable relative to the locking mechanism and the deflection mechanism. A device is coupled to the saddle and is extendable from and retractable within the sheath.

Abstract: A device comprises a retractable shaft; a shaft biasing spring; and an actuator button. The retractable shaft is biased away from the actuator button by the shaft biasing spring. A magnetic attracting force is created between the retractable shaft and the actuator button upon actuation of the actuator button. Before actuation, a distance between the actuator button and the retractable shaft is great enough that the magnetic attracting force is less than a biasing force of the shaft biasing spring such that the retractable shaft is biased away from the actuator button. Upon actuation, the actuator button is depressed to make the distance between the actuator button and the retractable shaft sufficiently small such that the magnetic attracting force is greater than the biasing force of the shaft biasing spring to allow the retractable shaft to be biased towards the actuator button.

Abstract: The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.
