摘要:
A flexible endoscopic device including an elongate flexible member having opposite ends, an effector assembly mounted on one of the opposite ends of the flexible member, and a handle mounted on the end of the flexible member opposite the effector assembly. The handle includes a fastener for receiving a portion of the flexible member spaced from the end of the member opposite the effector assembly. The device also includes an actuator assembly extending through the flexible member and operatively connected to the effector assembly for actuating the effector.
摘要:
A stamped jaw for use in an endoscopic device. The jaw includes a cup having opposite side walls extending longitudinally along the jaw, and an end wall extending between the side walls. The opposite side walls have a first tooth profile and the end wall has a second tooth profile different from the first tooth profile.

A stamped jaw for use in an endoscopic device including a cup having opposite side walls extending longitudinally along the jaw spaced equally from and on opposite sides of a longitudinally extending median plane, and an end wall extending between the side walls. The jaw also includes a hinge extension attached to the cup having a hinge pin opening adapted to receive a hinge pin to pivotally connect the jaw with an identical second jaw, an inner face surrounding the hinge pin opening extending along the median plane, and an outer face positioned to abut a clevis when assembled in the endoscopic device.
摘要:
A surgical instrument including an elongate member having opposite ends, and a clevis attached to one end of the opposite ends. The clevis has a pair of spaced arms. The instrument includes a pin extending between the spaced arms of the clevis, and an end effector having a pivot hole receiving the pin extending between the spaced arms of the clevis for pivotal movement relative to the clevis and a control arm for pivoting the end effector about the pin. The instrument also includes an actuator wire having a helical portion connected to the control arm of the end effector.

Disclosed is a respiratory cannula assembly to deliver and receive gases from a patient. The cannula assembly contains two oral prongs for delivering and receiving gases from the patient as well as at least one gas delivery nasal prong and at least one gas receiving nasal prong. The gas receiving nasal prong extends further into the patients nostril than the gas delivery nasal prong. The cannula assembly further contains a connector that aids in coupling to a medical device, the connector including independent oral and nasal moisture traps that remove moisture from exhaled patient gases.
摘要:
A conscious sedation system and a response testing apparatus for a conscious sedation system. A controller generates a request for a predetermined hand motion response from a patient and analyses at least a hand motion response made by the patient to the request to determine a level of sedation of the patient. The response testing apparatus includes a request assembly and a response assembly. The request assembly communicates to the patient the request generated by the controller. The response assembly senses the hand motion response and communicates the hand motion response to the controller.
摘要:
A surgical stapler having an end effector with a reduced stacking height for its components to decrease the diameter of a trocar cannula or other access device during minimally invasive surgery is disclosed. The end effector includes an elongated channel containing a staple cartridge and an anvil movable toward and away from the channel. The anvil is movable to first, second and third fixed positions relative to the channel. The first fixed position is a closed position which eliminates clearance between the anvil and cartridge. The second fixed position is an open position for inserting tissue between the anvil and cartridge. The third fixed position is a clamped position where a tissue-clamping gap exists between the anvil and cartridge to properly clamp tissue. The elimination of clearance between the anvil and cartridge of the first fixed position of the anvil reduces the stacking height, and therefore enables the user to insert the stapler through a smaller diameter access opening.
摘要:
A medical effector system comprised of a bedside unit and a procedure unit. The bedside unit contains a series of connection points for receiving inputs from a series of patient monitors. The procedure unit contains a patient monitoring and medical effector program, and a drug delivery pump or magnetic flux generator capable of delivering therapeutic energy to a patient. The medical effector system contains the capability to issue and receive a request from a non-sedated patient, issue and receive a request from a sedated patient and then to calculate a time difference. The medical effector program operates the pump or magnetic flux generator based upon at least some of the patient outputs and program inputs including a calculated time difference. A removable umbilical cable connects the two units and allows the output of the patient monitors as well as other information to travel between the two units.

The present invention is directed to an improved cable driven surgical biopsy device wherein a transmission assembly is disposed at a proximal end of the biopsy device. The transmission assembly being adapted to convert rotational motion of a cable entering the biopsy device of a substantially right angle into rotational energy to drive the axial cutter in the biopsy device.

An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfacing surface applying pressure in a predetermined range. A second pole is located one of the two interfacing surfaces. In a preferred embodiment, the second pole is located on the same interfacing surface as the first pole and an insulator electrically isolates the two poles. A preferred application of the invention is in a cutting instrument wherein a hemostatic line is formed along a cut line using RF energy.
