Title: NATURAL CHANNEL-BASED MICROSURGICAL DEVICE
Abstract:
A natural channel-based microsurgical device, comprising: a control box component (300); and a soft tube component (400), a flexible rod structure (500), and an end component (600) fixedly connected to a front-central part of the control box component (300) in that order. The soft tube component (400), the flexible rod structure (500), and the end component (600) have overlapping axes. The control box component (300) is used for positioning and changing a microsurgical instrument, for operation and support of a surgical tool (100, 200), and for implementation of a microsurgical procedure. The soft tube component (400) provides a channel, motion output, and load output for the microsurgical instrument and a transmission steel wire (116). The end component (600) provides support for operation of an end of the microsurgical instrument, increasing a range of motion of a surgical instrument. The device is easy to use, and provides precise motion and favorable real-time operation. The invention achieves a basic goal of microsurgery, increases motion flexibility and space for surgical instrument maneuverability, and allows microsurgery to be performed in a hand-held manner.
