A joystick includes: a base; a joystick shaft, four micro-switches, and a retaining ring. The joystick shaft is in operable connection with the base, and is surrounded by a trigger member and a limit member. The four micro-switches are fixed on the base, and are located in four cardinal directions of the trigger member, and four ordinal directions are formed between every two adjacent micro-switches. Each of the micro-switches is a mechanical-shaft-key switch. The retaining ring is configured to limit rotation angles of the joystick shaft. According to the joystick of the present application, the noise caused by the joystick can be effectively reduced, and the service life of the joystick can be prolonged, the directional output control in eight directions can be realized, and it is ensured that the micro-switches in the cardinal directions will not be damaged when the joystick performs the control operation in the ordinal directions.

The present invention provides a minimally invasive surgical instrument with a terminal steerable mechanism, comprising an intervention device, a control device and one or more wires. The strip-shaped intervention device sequentially includes a main section, a flexible section and an operation section from the top to the end. The control device includes a sphere with a preset rotational degree of freedom, and an operating lever connected to the sphere. Said one or more wires are extended along the main section of the intervention device. Here, the second ends of said at least one or more wires are connected to the flexible section or the operation section of the intervention device, and the first ends thereof are connected to at least a part of the control device.

A removable joystick for use with a video game controller includes a base shaft that is coupled to a joystick unit in the housing of the video game controller so that the proximal end of the base shaft extends to a location at or below an outer surface of the housing. A top shaft assembly is removably coupleable to the base shaft via a quick disconnect assembly. The top shaft assembly includes a top shaft with a proximal end that removably couples to a joystick ball, and a collar that is spring loaded and movably coupled to the top shaft and has a flange that extends outward from the outer surface of the collar. When the top shaft assembly is disconnected from the base shaft, the flange of the collar engages and retains a dust cover disposed over the collar to inhibit misplacement or loss of the dust cover.
