An electric-knife cleaning device useful in connection with surgery comprising a cleaning head mounted on a laminated base, the bottom lamina of which is a removable pull-off sheet adhered to said base by a tacky adhesive which remains on said base when said pull-off sheet is removed and is then operative to adhere said base to a surface, and the top lamina of which comprises means for mounting said cleaning head on said base, whereby the bottom lamina can be removed and the device adhered to a surface adjacent the situs of the surgery in a position convenient for cleaning the knife during the surgery, is disclosed, as well as a method for its production and use.

Method of making a device for cleaning electric knives

There is disclosed a method and apparatus for effecting cardio-valve replacement surgery. A clamp adapted to be fastened to an ether screen has multiple arms. These arms are linked together by a double clamp having two parts which are pivotable with respect to each other and within which the arms are both rotatable and slidable and which arms are simultaneously clamped in whatever position they may have been set. The clamping is effected by a draw bolt passing through both parts of the double clamp. At the free end of the arms is a clamp adapted to hold a replacement cardio-valve holder. The clamps and the arms are adjusted to present a replacement valve in a position such that it can be sutured into the heart of the patient without the surgeon having concern about the possibility of malalignment of the valve or suturing.
