Problems solved by technology

However, for medical systems, there are many moving parts that need to move for a long time, which requires the operator to operate the joysticks related to these moving parts all the time, and it is easy to cause the operator's hand fatigue, which may cause misoperation
This kind of operation for a long time can even cause diseases such as operator's hand strain

Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0046] figure 2 is a schematic diagram of a joystick according to an embodiment of the present invention. Such as figure 2 As shown, the joystick 100 mainly includes a handle 103 viewed from the outside of the joystick.

[0047] Of course, it can also be like figure 1 The shown conventional joystick 800 further includes a base 101 and a waterproof ring 102 . The base 101 is used to fix the joystick 100. For example, the base 101 is provided with a plurality of through holes, and the base 101 together with the entire joystick 100 can be fixed on the console through a plurality of screws. The waterproof ring 102 is disposed between the base 101 and the handle 103 for preventing water or the like from entering the interior of the joystick 100 and affecting the electrical environment i...

Abstract

The invention relates to a joystick. The joystick comprises a handle (103) with a casing (104) and also comprises an inductive electrode (105) and a control circuit (106), wherein the inductive electrode is arranged in the casing (104) and can form a capacitor (Cx) with the human body (115) outside the casing; the control circuit (106) is connected with the inductive electrode (105), and the control circuit ouputs a control signal when the capacitance of the capacitor (Cx) reaches a threshold. According to the technical scheme of the invention, the operator only needs to hold the joystick naturally when operating the joystick so as to connect the safe current loop without pressing the safe loop button with a finger, which brings convenience to the operator.

Description

technical field [0001] The invention relates to a joystick, in particular to a joystick used in medical systems such as X-ray machines, computed tomography (CT) equipment, and magnetic resonance imaging (MRI) equipment. Background technique [0002] Medical systems are increasingly used. For medical systems, there is a need to ensure patient and operator safety when moving parts are in motion. Therefore, the safety requirements for the motion control of the moving parts are very high, that is, the motion must be strictly controlled. For the control of moving parts, it usually includes the following three links: [0003] First, the acquisition of motion control signals. The motion control signal is input through the human-machine interface of the console, and the most commonly used methods are buttons and joysticks. [0004] Second, the transmission of motion control signals. Generally, it is transmitted from the console to the motion controller through a switch signal o...
