Abstract: An electrosurgical instrument includes a housing including an elongated shaft. A stationary actuation member is axially disposed within the elongated shaft and includes a cam pin. An actuating mechanism is operably coupled to the elongated shaft and is moveable relative to the housing to selectively cause movement of the elongated shaft. An end effector includes a pair of opposing first and second jaw members operably coupled about a common pivot. One or both of the jaw members includes a camming slot configured to engage the cam pin. Each jaw member includes an electrically conductive tissue sealing surface adapted to connect to a source of electrosurgical energy. A knife blade is supported in the elongated shaft and moveable in a longitudinal direction to cut tissue disposed between the jaw members. A switch is configured to be engaged by the actuating mechanism to initiate delivery of electrosurgical energy to tissue.

Abstract: A sutureless chest tube adhesion assembly configured to quickly and easily anchor a chest tube is described. The assembly generally comprises a notched flexible substrate adapted to adhere to human skin 415. A chest tube incision in a notched region of the substrate provides an entry point for the chest tube which is anchored to the substrate by way of an intermediate flexible membrane that covers and adheres to the chest tube and substrate. The intermediate flexible membrane has a matching notched region adapted to accommodate the chest tube. The chest tube and incision are adapted to be covered by a transparent cover sheet which covers and adheres to a portion of the substrate, the intermediate flexible membrane and to a portion of the human skin 415.

Abstract: Disclosed are embodiments describing finger calipers with a pair of lever arms pivotally attached to a hand plate via a pivot point at their respective proximal ends. Each of the lever arms extend along the length of a finger and attach to the end of the respective finger via a finger cuff or some other attachment means. Accordingly, the lever arms can open and close, or otherwise splay apart, in a scissor like manner when the fingers that they are attached to open and close or otherwise splay apart. A ratchet system comprised by one of the lever arms and the hand plate allow for one-way motion of the ratcheted lever arm. The other lever arm freely pivots across the hand plate. When a medical examiner is using the finger calipers, they can reliably measure a dilated cervix by reading a corresponding dilation measurement indicium associated with the ratcheted lever arm.

Abstract: A surgical forceps includes a first shaft member including a proximal portion having a handle at a proximal end thereof and a distal portion having a jaw member at a distal end thereof. The proximal and distal portions are pivotable between an aligned position and an angled position. A second shaft member includes a jaw member at a distal end thereof and a handle at a proximal end thereof. The shaft members are pivotable relative to one another between a spaced-apart position and an approximated position for moving the jaw members relative to one another between an open position and a closed position to grasp tissue therebetween. The proximal portion of the first shaft member is pivoted relative to the distal portion of the first shaft member from the aligned position to the angled position upon movement of the first and second shaft members towards the spaced-apart position.

Abstract: An integrated chest evacuation tube that is specifically configured to function as a closed tube when inserted and retained inside of a chest cavity to provide enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a fluid impermeable membrane fixedly attached to a single flexible hollow tube. The fluid impermeable membrane is interposed between an inlet port and an outlet port or optionally at said outlet port of a chest tube. The membrane is configured to seal the tube's passageway from any transfer of the fluid. The impermeable membrane is adapted to be ruptured by a force other than pressure from said fluid.

Abstract: A pliable arc-shaped chest tube that is specifically configured for being inserted and retained inside of a chest cavity provides enhanced benefits over the state of the art. The tube creates a passageway through which effluent can escape from a chest cavity, typically following trauma. The pliable arc-shaped tube can be bent to conform to a hand-held scalpel probe shaft when slid over the probe shaft. After being inserted into the chest cavity, the handheld scalpel is discarded while the chest cannula is retained or otherwise deployed within the chest cavity such that the pliable arc-shaped tube is arced towards the rib cage to enhance comfort following deployment.

The linkages are configured to move said scalpel blade in an elliptical path when said scalpel blade is deployed to extend outside of said probe tip housing.
