A medical forceps has a forceps shank and a forceps jaw which comprises at least one movable jaw part, wherein the jaw part has a curved linkage arm at its proximal end. The linkage arm is movably guided in a curved guide path of an insert which is inserted into at least one receiver at the distal end of the forceps shank.

Instrument for minimal invasive surgery

A medical instrument including a housing, a shank a proximal end and a distal end, the proximal end of the shank being connected to the housing, an openable and closable two-part tool provided at the distal end of the shank, an actuating element that runs through the housing and the shank so as to be axially shiftable for actuating the tool, and an elastic buffer as overload protection whereby the buffer elastically deforms to buffer an axial force overload transmitted from the actuating element onto the shank. The buffer is formed as a shaped body of elastic material arranged between the shank and the housing so that during overloading the buffer is deformed by the shank which at the same time shifts axially proximally with respect to the housing.

Medical instrument

The endoscopic instrument is formed as a needle holder with ligature scissors. It comprises at its distal end a jaw-like tool and at its proximal end a handle, these being connected to one another by a common shank. At the distal tool end there is formed the ligature holder and the ligature scissors proximally neighboring thereto. Between these tool parts there is formed a projection limiting the free passage between the needle holder and the ligature scissors, this projection being dimensioned such that although the ligature may be guided through, the needle however cannot get into the region of the scissors.

Needle holder

The endoscopic instrument comprises two working parts provided at the distal end region of an elongate shank, of which at least one is pivotingly movable relative to the other, and is provided with handle at the proximal end region of the shank for actuating at least one of the working parts via an actuation rod running in the shank, wherein the working parts in the region of their pivoting mounting submit to a spring force for pressing these parts onto one another. For achieving an exact bearing force of the working parts on one another and an increased security against their damage during use of the instrument the shank at its distal end is provided with a fork-shaped holder with two resilient distal fork arms producing the pressing force onto the working parts, whose at least one fork arm comprises a receiver bore. The pivotingly movable working part is inserted in the intermediate space formed by the two fork arms and is provided with a projecting joint peg which pivotingly engages into the receiver bore of the allocated fork arm of the holder.

Endoscopic instrument

An instrument for manipulating organs in endoscopic procedures in the interior of the body includes two spreading members at the distal end of the instrument. The spreading members can be swiveled outwardly and actuated by means of a handle at the proximal end of the instrument. A control member displaceably guided in the instrument shaft connects the handle and spreading members. The distal end of the instrument is bent in such a way that the spreading members spread out in a curved plane so that organs can be reliably guided with the manipulator.

Medical instrument employing curved spreading members to manipulate

A retrograde cutting hook punch for arthroscopy is so designed that two ends of a fixed and a pivotable jaw member which are remote from the axis of pivot of the pivotable jaw member are laterally positioned at an angle to the longitudinal axis of the forceps, the pivotable jaw member, which is pivotable between limits set by two abutments, having an axially directed part which is guided to pivot in a longitudinal slot in the fixed jaw member, said axially directed part being provided with a downwardly open longitudinal slot to receive a traction and thrust rod for actuating the pivotable jaw member.

Retrograde cutting hook punch

Medical forceps are described which have a fixed jaw part and swingable jaw part with which parts a fixed handle part and a swingable handle part respectively are associated. In order to limit the pressure force which can be produced on the jaw parts, the swingable grip part is divided into two parts which are undetachably connected on a line with each other by a flexural spring element. For the fixing of the gripping position of the jaw parts detent elements which come into detachable engagement with each other are provided on the grip parts.
