  • Patent number: 4331257
    Abstract: A closure for a container used in hospitals to store and transport items. The closure includes a cable tie with a locking eyelet at one end. The other end of the cable tie passes through an opening in the closure and then locks into the eyelet. The locking eyelet has a retaining element that prevents the removal of the cable end. The cable, when thus secured, prevents an unintentional opening of the closure and therefore an unintentional movement of a lid of the container to an open position. Preferably the closure is a falling latch and the cable passes through an opening in the falling latch. It is also secured around or to other elements to prevent the falling latch from moving to a position where the lid can open.

  • Patent number: 4331150
    Abstract: An approximator having at least one pair of parallel guide bars which are connected to each other rigidly on one of their adjacent ends, and having at least one clamp of which one is arranged longitudinally displaceable on the guide bars of a pair and is fixable on these in any desired displaced position. At least one additional bar pair each with respectively one displaceable and fixable clamp. The additional bar pair is pivotally connected with the at least one first mentioned bar pair and with respect to this bar pair is fixable in selective relative positions.

  • Patent number: 4316470
    Abstract: An approximator for anastomotic surgery having two parallel guide bars connected rigidly at one end to a fixed clamp holder. Another clamp holder is displaceably guided on the guide bars. One of the guide bars is a meshing bar non-rotatably mounted to the fixed clamp holder. A driver is mounted on the displaceable clamp holder rotatably about an axis crossing the longitudinal axis of the meshing bar and is formed with a toothed gear engaging the driving bar, the latter and the toothed gear forming a rack and pinion gearing.

  • Patent number: 4271837
    Abstract: The present invention relates to an electrosurgical cutting device for the cutting and/or coagulation of tissue with RF current. A cutting electrode and a patient plate are connectable to the terminals of a RF generator. A control system, using a condition change arising at the cutting area during cutting as a controlled value, serves to control the RF current produced by the RF generator as a manipulated variable. The invention is characterized in that, for control of the RF-voltage of the RF generator, the control system responds to d-c voltage that arises at the cutting area during cutting with the RF current.

  • Patent number: 4240432
    Abstract: A mucotome or mucous membrane cutter for mucogingival membrane surgery is disclosed. The mucotome comprises a handle having a small, compactly designed cutting head arranged on its forward end, the cutting head including a circular cylindrical blade-holding roller which is reciprocable parallel to the blade edge in a guide by means of a drive shaft having an eccentric crank pin engaging in cross grooves of the blade-holding roller. A cutting shoe is mounted to the ends of the blade-holding roller and is rotatable relative to the cutting head through a limited angle. The cutting head is also selectively positionable in at least two angular positions relative to its support. The cutting blade is secured in a longitudinal radial slot in the roller and projects therefrom through a guide slit formed in a crosspiece of the cutting shoe. The construction and arrangement of the cutting head and cutting shoe assure a compact, versatile structure having a number of adjustment possibilities.

  • Patent number: 4192315
    Abstract: This disclosure relates to a clip for surgical purposes comprising a coil spring having at least one loop and a pair of crossing legs. The ends of the legs which extend beyond the crossing point are formed as clamping jaws. Because the portions of the legs adjoining the loop extend generally parallel to one another and the ends of the legs run side-by-side, and because a ring is provided at the crossing point for holding the legs together, the clip can be constructed with such small dimensions that it is particularly advantageously useful for neurosurgical purposes.

  • Patent number: 4116200
    Abstract: A surgical milling tool with a hand-operated milling machine for milling the heads or sockets of bone joints of spherical shape is disclosed. The tool is formed of a hemispherical cup integrally formed with a cylindrical skirt and flange and is provided with a plurality of openings of semi-oval shape, each having a cutting edge arranged at the minor axis of the oval shape. The openings are situated such that, upon rotation of the cup, the cutting edges thereof overlap to provide a continuous cutting edge surface conforming generally to the shape of the cup.
