  • Publication number: 20220354507
    Abstract: The disclosure relates to a hemostatic device (1) comprising at least a first chamber (100) configured to be fluidically connected to a fluid source and a second chamber (200) configured to be fluidically connected to a vacuum source, wherein the hemostatic device comprises a first membrane (201) fluidically isolating the second chamber (200) from the first chamber (100) and a second membrane (202) configured to be placed so as to face, at least partially, a bleeding area of a natural body cavity, the second membrane (202) comprising a plurality of through holes (203) leading into the second chamber (200) and configured to induce a negative pressure in the natural body cavity when a negative pressure is applied in the second chamber (200) by the vacuum source, the induced negative pressure being configured so that the walls of the natural body cavity are attracted to the second membrane (202).

  • Patent number: 8920433
    Abstract: A manipulator includes a control unit (1), with handle (4) and control buttons (4a-4d), and a connecting arm (2) which, at its proximal end (2a), carries the control unit (1) and, at its distal end (2b), carries a work unit (3). The control buttons (4a-4d) control at least a first inclination motor, which causes a movement of inclination of a tool support (5) of the work unit (3) about a transverse inclination axis (11), and they control the actual rotation of the tool support (5) about its direction of inclination (II) and control the orientation of the direction of inclination (II) about the longitudinal axis (I-I) of the connecting arm (2). A particularly ergonomic manipulator is thus obtained which is easy to learn to use and which efficiently separates the stresses arising from movements of the tool support (5) and the stresses arising from holding and moving the manipulator itself.

  • Patent number: 8821512
    Abstract: A manipulator includes a control unit (1), with handle (4) and control buttons (4a-4d), and a connecting arm (2) which, at its proximal end (2a), carries the control unit (1) and, at its distal end (2b), carries a work unit (3). The handle (4) is articulated about at least one transverse articulation axis (4e), which is itself situated at an intermediate position along the handle (4). A particularly ergonomic manipulator is thus obtained which is easy to learn to use and which efficiently separates the stresses arising from movements of the tool support (5) and the stresses arising from holding and moving the manipulator itself.

  • Patent number: 8696651
    Abstract: A manipulator includes a main arm, of which the proximal end bears a drive, and a proximal manipulation structure, and of which the distal end bears a controlled distal structure that may itself bear a surgical tool. The main arm passes through a surgical trocar. The proximal manipulation structure includes two opposed contact zones and stress sensors positioned in a central zone between the two opposed contact zones. The stress sensors operate the drive as a function of the stresses applied to the contact zones in order to produce the pivoting and rotating movements of the surgical tool with respect to the main arm. This ensures that there is optimal decoupling of the movements in the various degrees of freedom, thus making it easier to obtain movements through stressing operations that are natural to the operating surgeon.

  • Patent number: 8613740
    Abstract: A hand-held manipulator includes a handle (4) fixedly mounted on the end of a connecting arm (2), the distal end (2b) of which carries a work unit (3). The handle (4) includes a grip section (4e) having a surface of revolution about a longitudinal handle axis (III), which is aligned with the longitudinal axis (I) of the arm. Control elements (4a-4c) are shaped in an annular structure near the distal end (4f) of the grip section (4e) so as to be accessible in any angular orientation of the hand holding the handle.
