threaded section 14 is a nut 17, tightly securing handle 2 to cylinder 5. Handle 2 has a
central bore 18 extending through it longitudinally and accommodating electric cable 12.
The end remote from threaded section 14 has a negative plug component 19
connected to cable 12. Extension 3 is, like handle 2, shaped like a rod, with one end
having a positive plug component 20 that fits into the negative component on handle 2.
The other end of extension 3 has another negative plug component 21. When handle 2
and extension 3 are connected, a union nut 22 that moves back and forth axially
between two stops on handle 2 engages a threaded section 23 on extension 3.
Extension 3 also has a central bore 24 extending through it longitudinally and
accommodating an electric cable 25 that connects plug components 20 and 21. A
subassembly with the negative plug component 21 in extension 3 constitutes a positive
plug component 26 that is connected by way of another electric cable 27 to equipment
4. The essential elements of equipment 4 are, as schematically illustrated in Figure 1,
an electric signal generator 28, an audio alarm and a battery 29 that powers the
apparatus. All these components are of course electrically connected to electric cable
27. The other essential components needed to operate conventional ultrasound
apparatus can be accommodated in equipment 4.
