摘要： A microsurgery tool for use in anastomosis of small vessels has a thin shaft with a pair of forwardly projecting tines defining a throat for receiving the pointed end of a suture needle. The microsurgery tool is inserted between confronting ends of vessels into engagement with the inner wall of one vessel for receiving a suture needle point passing through the outer wall of the vessel and thereafter is withdrawn from the space between the vessels to engage the outer surface of the other vessel where it receives the pointed end of the same suture needle passing through the inner wall of the other vessel.

摘要： A normally closed clamp is provided which is formed from two extruded elements which are connected together in their midregion by means of a non-circular cam on a base element and a corresponding non-circular cam surface on a clamping element. In the normally closed position, the cam and cam surface urge the device into a jaw-closed position with the handles being spaced-apart. When the handles are brought together, the jaw members separate and the relative position of the cam surface and the cam member is altered. The device may be used as a tissue separator. Two of the devices may be assembled together as a tendon approximator.

摘要： A microscope has a voice activated control system which permits precise location of the microscope and precise focusing by means of voice commands uttered by the microscope operator. When the microscope is in a movement mode, the movement is terminated by any sound exceeding a pre-established acoustic threshold level. Any microscope location can be identified and appropriate data is stored in a memory drive to permit the microscope to return to an identified location with a single voice command. The microscope is combined with a screen monitor and/or an acoustic speaker to provide visible and/or acoustic responses from the control system. The system is practical for retrofitting existing remotely controllable microscopes.

摘要： A marking device provides a circular mark on the skin of the breast of a patient concentric with the areola of the patient's breast. The device is a cylindrical tubular member having an open circular end which is the marking element and having a pair of cross markings at the other end on an optically transparent wall to permit optical centering of the device with respect to the breast areola prior to skin marking. A preferred embodiment includes a pair of markers in a common cylindrical tubular member having one circular diameter at one end and a different circular diameter at the other end.

摘要： A microsurgery tool for use in anastomosis of small vessels has a thin arcuate shaft or tube with a tubular distal end having its tubing cut away to define a trough for receiving the pointed end of a suture needle. The microsurgery tool is inserted between confronting ends of vessels into a first vessel for receiving a suture needle point passing through the outer wall of the first vessel. Thereafter the tool is withdrawn from the space between the vessels and the convex outer surface of the trough engages the outer surface of the second vessel where it supports the wall of the second vessel while the point of the same suture needle is passed through the inner wall of the second vessel.

摘要： An improved method for expanding the open ends of human vessels employs an expandable cell which can be inflated a bubble at the open end of a vessel. The method is carried out with a novel closed end cell which can be connected to a source of fluidized pressure such a hypodermic syringe and, in its relaxed state can be introduced into the open end of the vessel for subsequent expansion into a bubble of the desired diameter to cause uniform length extension of the open end of the vessel. The cell may be prestressed or weakened to establish the location of bubble formation within the cell.

摘要： A new method and apparatus for the long-term removal of hair are provided. Ultrasonic energy is transmitted to a needle passed through the skin into an individual hair follicle. The resulting cavitation of the area surrounding the hair follicle causes the hair follicle to be disrupted. The process is repeated for individual hair follicles over the selected region of the body.
