Bone marrow aspirate harvesting is provided via use of a surgical device that includes a needle including a plurality of lateral holes defined at different positions longitudinally along a wall thereof and a movable aspiration insert within the needle, wherein the needle need not be repositioned within the patient to harvest bone marrow aspirate. The surgical device includes a needle with lateral holes; a movable aspiration insert including an aspiration window that is sized to interface with one lateral hole of the plurality of lateral holes at a time, wherein the aspiration insert is disposed in a lumen of the needle; and a handle including a positioning means in communication with the aspiration insert, wherein the positing means is configured to actuate between a first state and a second state to move the aspiration insert a certain distance in a first direction along a longitudinal axis of the needle.

A method and apparatus for performing electrocautery on a site of a subject that includes inserting a trocar device into the location of the site of the subject and electro-cauterizing the site of the subject using a diode included with the trocar device. A method and apparatus for performing electrocautery on a site of a subject that includes inserting one or more medical tubes or medical instruments or devices that extends through an expandable sheath; and electro-cauterizing the site of the subject using a diode included with the expandable sheath device.

A surgical access device includes a housing with an elongate tubular member extending distally from the housing. The elongate tubular member has an open distal aperture. A first electrode is disposed in a first region of the elongate tubular member and circumscribes the elongate tubular member. The first electrode is coupled to an anode of a power supply and is configured to provide airborne particulate matter with a negative electric charge. A second electrode is disposed in a second region of the elongate tubular member and circumscribes the elongate tubular member. The second electrode is coupled to a cathode of a power supply and is configured to attract the airborne particulate matter.

An apparatus includes a proximal structure configured to be positioned extracorporeally relative to a patient and defining a primary axis, and a distal structure extending distally from the proximal structure and configured to be passed through a body wall and into a body cavity of the patient. The distal structure cooperates with the proximal structure to define a working channel sized and configured to receive and guide a surgical instrument distally therethrough. The distal structure includes a proximal portion and an angled distal portion. The angled distal portion defines a secondary axis that is angled relative to the primary axis. At least the angled distal portion of the distal structure is rotatable relative to proximal structure about the primary axis.

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath and a staple driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The staple deck defines a plurality of staple openings in at least one annular array. Each staple opening in the plurality of staple openings houses a staple. The anvil is configured to actuate relative to the staple deck to compress tissue between the staple deck and the anvil. The staple driving mechanism is configured to actuate the first staple driver to fire a first staple of the plurality of staples against the anvil. The staple driving mechanism is further configured to actuate the second staple driver independently of the first staple driver to fire a second staple of the plurality of staples against the anvil.

The invention relates to a method and an automatic disinfection machine for the controlled disinfection of the skin of a patient comprising a treatment chamber for accommodating the body part with the skin to be disinfected; an electrically controllable disinfecting device for disinfecting the skin, a recording device for recording the disinfection of the skin in the form of disinfection data, a data processing control device for controlling the disinfecting device and the recording device. The control device is thereby designed to effect the disinfection of the skin by controlling the disinfecting device, record the disinfection of a skin section of the skin in the form of disinfection data by controlling the recording device.

A surgical instrument includes: an end effector; a power source; a motor coupled to the power source, the motor configured to actuate the end effector; and a controller operatively coupled to the motor and configured to control the motor based on a current draw of the motor and an angular velocity of the motor.

A penetrator assembly for penetrating a bone and associated bone marrow is provided. The penetrator assembly may include a first connector having a first end and a second end; an outer penetrator extending from the second end of the first connector; the outer penetrator comprising a longitudinal passageway and a first tip; a second connector having a first end and a second end; and an inner penetrator extending from the second end of the second connector, the inner penetrator comprising a second tip. The first connector may be configured to engage the second connector, and the inner penetrator may be disposed in the longitudinal passageway of the outer penetrator when the first connector is engaged with the second connector.

An apparatus and method for penetrating bone marrow is provided. The apparatus may include a housing such as a handheld body, a penetrator assembly, a connector that releasably attaches the penetrator assembly to a drill shaft, a gear mechanism, a motor and a power supply and associated circuitry operable to power the motor. The penetrator assembly may include a removable inner trocar and an outer penetrator or needle. It may also include a grooved trocar that allows bone chips to be expelled as the apparatus is inserted into bone marrow. Various connectors are provided to attach the penetrator assembly to the drill shaft.
