摘要： An electromagnetic suturing device comprises a body, a coil in the body and a suturing element actuatable by a magnetic suturing track extending into the first end face, a second arm having a second end face opposing the first end face, a second suturing track extending into the second end face, a coil in the first arm, and a suturing element drivable by a magnetic field generated by the coil to move from the first suturing track to the second suturing track. An electro-magnetic hammer suturing device comprises a housing and a coil in the housing, a shuttle to reciprocate in the housing by an electromagnetic field generated by the coil and a suturing element to be actuated by the shuttle.

摘要： Systems and techniques for nerve monitoring are described herein. The system can include a remote transmitter configured to send a stimulation signal to a nerve, and an electrosurgical device including an end effector configured to perform a surgical function in response to receiving a therapeutic signal from an electrosurgical generator. The system can also include a receiver configured to detect the stimulation signal, and in response to detecting the stimulation signal, determine a location of the nerve, and an in-vivo transmitter configured to emit a location signal in response to the determined location of the nerve.

摘要： Surgical instruments and methods are disclosed including a tissue removal tool for treatment of endometrial tissue on a background tissue of a patient. The tissue removal tool can optionally comprise a graspable portion, a shaft and an end effector. The shaft can be coupled to the graspable portion. The shaft can have a proximal portion and a distal portion and can be configured to access an anatomic location of the endometrial tissue. The end effector can be coupled to the distal portion of the shaft. The end effector can be configured to lift the endometrial tissue relative to the background tissue to a lifted position. The end effector can be configured to cut the endometrial tissue from the background tissue with the endometrial tissue in the lifted position.

摘要： A surgical device comprises a shaft extending between proximal and distal portions, a surgical tool located at the distal portion, a handpiece located at the proximal portion, a lumen extending through the shaft from the proximal portion to the surgical tool, a light conductor extending into the proximal portion and at least partially through the shaft, and a light emitter connected to the light conductor to emit light from the light conductor toward the surgical tool. A method for illuminating dye while performing a laparoscopic surgical procedure comprises making an incision in a patient to form a laparoscopic port, marking target tissue for removal with a dye, inserting a laparoscopic device into the port, emitting light from a light source, passing the light through the laparoscopic device to illuminate the target tissue within the patient, and removing the target tissue with a surgical tool attached to the laparoscopic device.
