Abstract: A flexible surgical tool system includes: a mechanical arm (10) comprising a first continuum segment (12), a rigid connection segment (13), and a second continuum segment (14), the first continuum segment (12), a rigid connection segment (13) and the second continuum segment (14) being sequentially associated to form a dual continuum mechanism; a surgical effector (50) connected at distal end of the second continuum segment (14); a transmission driving unit (20) associated with the rigid connection segment (13) and with a surgical effector (50), respectively, and operable to drive the first continuum segment (12) to bend in any direction to drive the second continuum segment (14) to bend in an opposite direction, and to drive the surgical effector (50) to rotate in a first plane and/or open and close in a second plane. The flexible surgical tool system can be applied to a natural orifice or a single surgical incision of a human body and perform operations.

Abstract: A battery management chip circuit on the basis of an SOI process. The battery management chip circuit comprises a high-voltage multiplexer MUX, a voltage reference circuit, a Sigma-delta ADC (comprising an analog modulator and a digital filter), an SPI communication circuit, a function control circuit and a voltage value register. The battery management chip circuit is integrated on the basis of an SOI high-voltage process, and particularly, high-voltage MOS transistors adopted by the battery management chip circuit are high-voltage MOS device units on the basis of the SOI process. In addition, the present invention highlights the design of interface circuit-chopper circuit of the high-voltage multiplexer MUX and the Sigma-delta ADC, so as to describe the advantages such as decrease of difficulty of circuit design and reduction of layout area brought about when the present invention adopts the SOI process design and tape-out.
