Abstract: What is described here is a trocar sleeve for endoscopic applications, comprising an elongate part including at least one passage for insertion of an instrument such as an endoscopic, scissors or the like, and pivotable parts mobile on the distal end. The inventive trocar sleeve is characterized by the provision that the distal section is formed by several longitudinal sections articulated on the proximal section of the trocar sleeve, and that a mechanism is provided for pivoting the individual longitudinal sections about an axis orthogonal on the longitudinal axis of the trocar sleeve.

Abstract: An instrument for application in endoscopic surgery has a shaft provided with a plurality of ducts, two of which receive forceps elements and one of which receives a surgical instrument for cooperation with the forceps elements. One of the forceps elements has a distal end pivotal about a pivot axis which extends orthogonally to a longitudinal axis of the shaft, so that the distal ends of the forceps elements can be displaceable at a distance greater than on outer dimension of the shaft upon its insertion into a corporeal cavity.

Abstract: What is described here is an instrument for application in endoscopic surgery, comprising a shaft (10) including two forceps elements at its distal end which are operable independently of each other by operating elements (17), whereof one is pivotable about an axis at least approximately orthogonal on the longitudinal axis of the instrument and including at least one continuous passage (12) between the jaws of said two forceps elements. The inventive instrument is characterised by the provisions that the other forceps element is not pivotable, and that the pivotable jaw element or elements (16) of each forceps element are pivotable about axes (16a) which are each arranged approximately in parallel with the connecting line between the seizing regions of said forceps elements.

Abstract: A trocar mandrel has a tip permitting the piercing through the abdominal wall, and an insufflation passage extending along a longitudinal axis and spaced radially from a longitudinal axis of the trocar mandrel. The trocar mandrel recieves an insufflation needle, which includes a latterally disposed opening for the discharge of the insufflation fluid.

Abstract: A surgical instrument system, in particular, for use in non-endoscopic surgery having a surgical instrument provided with a shaft in which a supply channel having a distally disposed liquid emergence opening and an evacuation channel having a distally disposed liquid draw-off opening, and a pump device which pumps a liquid into the supply channel with such a pressure that the tissue in front of the distal end of the surgical instrument is separated along natural separation planes by the liquid emerging from the emergence opening, and the liquid out of the liquid bubble surrounding the distal end of the surgical instrument is pumped through the evacuation channel to the proximal end of the surgical instrument.

Abstract: What is described here is a trocar mandrel having a tip permitting the piercing through the abdominal wall, and having an insufflation passage extending along the direction of the longitudinal axis of the trocar mandrel, with the axis and hence the distal discharge opening of the passage being spaced from the tip by a distance along the direction orthogonal on the longitudinal axis.

Abstract: An instrument for application in endoscopic surgery has a shaft provided with a plurality of ducts, two of which receive forceps elements and at least one of which receives a surgical instrument for cooperation with the forceps elements. Each of the forceps elements has a distal end pivotal about a pivot axis which extends orthogonally to a longitudinal axis of the shaft, so that the distal ends of the forceps elements can be displaceable at a distance greater than on outer dimension of the shaft upon its insertion into a corporeal cavity.

Abstract: The invention concerns a surgical apparatus for the irrigation and aspiration of the operative cavity during endoscopic surgery. The apparatus comprises a reservoir of liquid for irrigation of the cavity, a pump for circulating the liquid in the cavity, a pressure measuring and control means, such as a piezometric cell and valve for measuring and controlling pressure in the cavity and a flow control means for controlling the flow of the liquid. The apparatus also provides temperature control means by which the temperature of the liquid may be adjusted, which along with pressure control means and adjustment of pressure of the liquid in the cavity, provides a desired hemostatic effect during the surgical process.

Abstract: Operative coelioscopy surgical apparatus for receiving electrical instruments, flexible mechanical instruments and rigid mechanical instruments. The apparatus includes a tubular canula and a handle member which is removably attached to the canula by a bayonet-type connection. The handle is provided with a series of control members which may be operated either simultaneously or separately, and these comprise a first push-button for controlling the transmission of irrigation fluids through the canula, a second push-button for controlling the aspiration of irrigation or body fluids through the canula, a third push-button for supplying electrical power and a lever member for mechanically controlling the movement of rigid and flexible instruments.
