Supply unit for accommodating medical instruments

A medical instrument supply unit and medical instrument combination comprising:

• a medical instrument with a middle part with lateral guide surfaces and with pin mounts, a power plug/jack connection a data transmission plug/jack connection and a pneumatic plug/jack connection;
• a supply unit with a height stationary part and a height-adjustable middle part with side surfaces for engaging the medical instrument middle part of said medical instrument, the side surfaces being complementary to the lateral guide surfaces of the medical instrument and with pins arranged at the middle part of the supply unit projecting upwardly, a power supply with a power plug/jack connection provided at said height-adjustable middle part, a data transmission facility with a data transmission plug/jack connection provided at said height-adjustable middle part, a pneumatic supply with a pneumatic plug/jack connection provided at said height-adjustable middle part and end position sensors provided at said height-adjustable middle part of the supply unit, said end position sensors sending a corresponding signal to an evaluating and control unit when the height-adjustable middle part of the supply unit has been moved upward to the extent that said pins are completely accommodated by said pin mounts whereby said connection for said power supply, said connection for said data transmission and said connection for said pneumatic supply are in an active state.

A medical instrument supply unit and medical instrument combination comprising:

• a medical instrument with a middle part with lateral guide surfaces and with a lower surface having pin mounts and an adjacent lower surface power plug/socket connection facility, an adjacent lower surface data transmission plug/socket connection facility and an adjacent lower surface pneumatic plug/socket connection facility;
• a supply unit comprising a power supply, a data transmission facility, a pneumatic supply, a ceiling suspended part and a height-adjustable middle part connected to said ceiling suspended part and adjustably movable relative to the ceiling suspended part, said middle part having side surfaces for engaging the medical instrument middle part of the medical instrument, the side surfaces being complementary to the lateral guide surfaces of the medical instrument middle part, said supply unit middle part having an upper surface with support pins projecting upwardly for mating with said pin mounts, said supply unit having an upper surface power plug/socket connection facility matable with said lower surface power plug/socket connection facility, an upper surface data transmission plug/socket connection facility matable with said lower surface data transmission plug/socket connection facility and an upper surface pneumatic plug/socket connection facility matable with said lower surface pneumatic plug/socket connection facility;
• a control unit for controlling the operability of each of said power supply, said data transmission facility and said pneumatic supply;
• and
• end position sensors connected to said supply unit for sending a signal to said control unit when the height-adjustable middle part of the supply unit has been moved upward to an extent indicating that said pins are accommodated by said pin mounts and connections of said power supply, said data transmission facility and said pneumatic supply are in a mated state.
