TL;DR: In this paper, an elongate forceps member is inserted into a biopsy channel and a staple is provided with locking elements for locking the staple in a closed postfiring configuration.
Abstract: A surgical instrument comprises an elongate forceps member (34) having a diameter sufficiently small so that the forceps member is slidably insertable into a biopsy channel (24) extending longitudinally through a tubular endoscope member (26), the forceps member being provided at a distal end with a pair of forceps jaws (34a, 34b) each formed on an inwardly facing surface with a longitudinally extending groove (36). A staple (32) having a spring bias construction tending to force the staple into an opened configuration is disposed in a closed prefiring configuration between the jaws and has a pair of legs (32a, 32b) each disposed in the closed prefiring configuration in a respective one of the grooves in the forceps jaws. The staple is provided with locking elements for locking the staple in a closed postfiring configuration.
TL;DR: An adjustable angle medical forceps is described in this article, which has a rotatable arm attached to a jaw element and provides increased surgical dexterity for suturing with curved or straight needles, for dissecting bodily organs and for isolating nerves, arteries, and the like.
Abstract: An adjustable angle medical forceps is disclosed which has a rotatable arm to which is attached a jaw element and which provides increased surgical dexterity for suturing with curved or straight needles, for dissecting bodily organs, and for isolating nerves, arteries, and the like. The forceps includes a laser fiber and irrigation and suction catheters for lasing, irrigating, and suctioning.
TL;DR: An electrosurgical coagulation instrument specifically designed to be insertable through a cannula for use in coagulating tissue during a laparoscopic or other scope-type procedure is described in this paper.
Abstract: An electrosurgical coagulation instrument specifically designed to be insertable through a cannula for use in coagulating tissue during a laparoscopic or other scope-type procedure. The instrument has both bipolar forceps jaw paddles and bipolar needle electrodes. The needle electrodes are selectively extendable from the distal end of the instrument by manipulation of a knob member in a proximal handle. The needle electrodes can be extended to thereby enter certain tissue such as a tumor to thereby effectuate desiccation thereof and a gradual shrinkage.
TL;DR: In this paper, an electrosurgical bipolar forceps for sealing is described, which includes one or more shaft members having an end effector assembly disposed at the distal end of the forceps.
Abstract: An electrosurgical bipolar forceps for sealing is disclosed. The forceps includes one or more shaft members having an end effector assembly disposed at the distal end. The end effector assembly includes two jaw members movable from a first position to a closed position wherein the jaw members cooperate to grasp tissue at constant pressure. Each of the jaw members includes an electrically conductive sealing plate connected to a first energy source which communicates electrosurgical energy through the tissue held therebetween. The electrosurgical energy is communicated at constant voltage. The electrically conductive sealing plates are operably connected to sensor circuitry which is configured to measure initial tissue impedance and transmit an initial impedance value to a controller. The controller determines the constant pressure and the constant voltage to be applied to the tissue based on the initial impedance value.
TL;DR: In this article, an external forceps channel add-on device for an endoscope is presented, which is capable of providing two forceps channels or more without controlling the luminous intensity and the field of view of the endoscope, capable of extracting a substance larger than the bore diameter of the forceps-channel multiple times while using the endosc in a state of not being drawn out, without imposing a heavy burden on a patient, and also capable of performing examination after an operation as to whether complications are incurred after the evulsion, whether there is any other affected part
Abstract: The present invention was made in the light of the foregoing backgrounds, and an object thereof is to provide a forceps channel add-on device for an endoscope, provided on an outer periphery of an insertion portion of the endoscope. The forceps channel add-on device for an endoscope is an external forceps channel device for an endoscope, which is capable of providing two forceps channels or more without controlling the luminous intensity and the field of view of the endoscope, capable of extracting a substance larger than the bore diameter of the forceps channel multiple times while using the endoscope in a state of not being drawn out, without imposing a heavy burden on a patient, and also capable of performing examination after an operation as to whether complications are incurred after the evulsion, whether there is any other affected part overlooked, and so forth. An external forceps channel device for an endoscope, provided with an external forceps channel which is capable of being repeatedly inserted and extracted in a way of being guided by a guide provided on an endoscope separately and independently therefrom along an outside of an insertion portion of the endoscope while using the endoscope without drawing it out, the endoscope incorporating an air supply path, a light source, a CCD camera, and a forceps channel and including the insertion portion and an maneuvering portion, characterized in that provided is the external forceps channel capable of repeatedly extracting a foreign substance larger than a bore diameter of the incorporated forceps channel in a way of being guided by the guide along the outside of the endoscope, together with the whole external forceps channel itself in a state where the foreign substance is grasped by forceps inserted through the external forceps channel, and that provided is the external forceps channel capable of being repeatedly inserted in a way of being guided by the guide along the outside of the endoscope in a state where the endoscope is not drawn out.
