An endoscope has a tubular shaft for receiving a viewing lens and a treatment instrument. The shaft has a distal end portion of channel-shape, providing a viewing window for the viewing lens. The circumference of the shaft is of oval cross-section around which the wall of the channel-shaped portion extends asymmetrically. An aperture recess forming an additional viewing window for the viewing lens is provided in the wall of the end portion. The endoscope is particularly suitable for use in endoscopic operations in the female breast, since the additional viewing window allows inspection of an implant before opening a capsule surrounding the implant.

The instrument for sample tissue specimens comprises an inner shaft extending eccentrically through a distally closed outer shaft and intended for reception of an optical system comprising a lateral objective, which inner shaft is distally connected or connectible to a cutting edge which cooperates with an edge of a distal lateral viewing and cutting aperture in the outer shaft acting as a mating cutting edge over the area of this distal lateral aperture by axial displacement of the inner shaft within the outer shaft.

The applicator for inserting a pessary into the uterus, which pessary comprises a chain combined with a distal coil screwable into the base of the uterus. The applicator has an inner shaft, which received the chain in its leading end, installed in an outer shaft and with its leading end securing the nearer of the coil in a formlocked or forcelocked manner, as well as a handle at the opposite end of the shaft whose rotation and axial displacement allow screwing the coil out of the outer shaft and into the base of the uterus to the extend of its longitudinal dimension. The outer and inner shafts are withdrawable from the uterus with respect to the screwed-in coil and chain which are to be released, after completion of the application. 7

This invention relates to forceps for applying a clip to a Fallopian tube. The clip is in one piece and made of a somewhat flexible plastics material. It has two separable arms which are connected by a flexible strip: one of these arms has a catch recess in a free end thereof to face the strip, into which recess the end of one of said spring arms is pressable by elastic deformation.According to the invention the forceps have an outer shaft to receive the clip open in a distal cut-out with the straight arm extended; the forceps additionally comprise two proximal handle members for opening and closing and consisting of a pivotally arranged two-armed closing lever. One arm of this closing lever has a distal flat face flush with the outer shaft so the forceps may be inserted through an outer trocar tube. Abutting against the straight clip arm and proximally in front of it is a projection; the other arm of the two-armed lever is pivotally connected to a rod which is axially stopped with respect to the pivot bearing of the closing lever by a proximal handle members and is distally movable and then is distally movable with the pivot bearing so that the projection of the closing lever becomes aligned against the straight clip arm and so that, by leaving the closing lever bearing in position, the rod is proximally movable to close the clip.

A medical instrument includes a handle on the proximal end and a shank rotatably arranged on the handle. A tool is arranged on the distal end of the shank. This tool is rotatable relative to the shank. An actuation element is arranged on the handle. The actuation element may be moved into at least two switch positions, wherein in a first switch position the actuation element is coupled in movement to the shank and in a second switch position the actuation element is coupled in movement to the tool.

A wound closure device is provided with at least one conical, proximal section, which tapers in the distal direction, and a tapered, distal section connecting thereto. A through-hole extends through the proximal section from the proximal end to a transition region precisely between the proximal and the distal sections and intersects the longitudinal axis of the wound closure device. A marking for the insertion depth is incorporated on the distal section distally spaced from the distal end of the through-hole.

In the inside of an outer shank there are formed a supply channel and a discharge channel which extend parallel to the outer shank. The suction channel has a larger cross section than the supply channel.

Disclosed is a ball-and-socket joint connection, in particular for a holding arm system for holding surgical instruments, with a joint ball sitting in a seat of a joint casing and permitting rotation in several axes and with a ball-shaped joint socket which can be axially displaced to and from the joint ball in a cylindrical section of the joint casing. A magnet is provided which produces a magnetic force between the joint ball and the joint socket such that they are drawn to one another. An actuation element is provided for displacing the joint socket and with this the joint ball is fixable in the seat of the joint casing by way of retracting the joint socket, wherein the joint ball by way of the magnet force is pressed into the seat of the joint casing, and wherein the joint ball by displacing forwards the joint socket with the actuation element is separable from the seat.

An electrode for vaporizing tissue is disclosed which has a head provided with projections and recesses and which is supported by at least one externally insulated electrically conducting branch. In order to provide a better and more effective electrode with regard to vaporization power and which can be easily cleaned and cheaply manufactured, the head which is rigidly fixed to the branch comprises essentially of part of a rotationally symmetrical body.

The instrument for morcellating, in particular for endosurgical operations, includes a tube with a cutter formed at its distal end which is the actual morcellator, and a gripping instrument introduced into this tube for holding the tissue to be removed. Between the gripping instrument and the cutting tube is provided a protective sheath into which the gripper of the gripping instrument is inserted before the beginning of the cutting procedure. This configuration reliably prevents fouling between the cutting instrument and the gripper.
