Positioning system of suspended medical device

Abstract

The invention discloses a positioning system of a suspended medical device, comprising a positioning adjusting block fixed with a sky rail, a bolt assembly and a positioning assembly fixed with a trolley, wherein the bolt assembly is spliced and matched with the positioning adjusting block; and the bolt assembly is connected with the positioning assembly through a buffer spring. With the scheme, when a bolt is clamped into a clamping groove of the positioning adjusting block, the whole system is stably and accurately positioned and is convenient for a doctor to operate a machine because the buffer spring plays a role of buffering the positioning adjusting block and the trolley.

Description

【Technical field】 [0001] The invention relates to a positioning system of a medical device. 【Background technique】 [0002] There are two ways to locate the X-ray generating device at the chest position and under the bed in the existing suspension type medical X-ray photography system: 1. After using the sensor to sense the set chest position and the position under the bed, through the control The brake device brakes to complete the trolley positioning function; 2. Use the latch structure to position the trolley, and install the latch stopper on the position where the fixed body needs to be positioned. When the moving body moves to the corresponding position, use the latch to snap into the latch stopper to complete the positioning function. [0003] The method of using sensor positioning can save more complex mechanical structures, but because of the limited accuracy of the sensor, there is a delay or overshoot in the control of the braking device, so the positioning accura...

Problems solved by technology

[0003] The method of using sensor positioning can save more complex mechanical structures, but because of the limited accuracy of the sensor, there is a delay or overshoot in the control of the braking device, so the positioning accuracy of this method is not high, resulting in misalignment Accurate, so using the sensor to locate the position is not accurate

Using the pin structure for positioning can ensure its positioning at an accurate position through the mechanical structure. However, due to the heavy weight of the trolley and the device carried by the current method, the mechanical positioning will have a large impact on the system and cause large vibrations and easily damage the mechanical structure. It also has a certain impact on the operation of doctors
