Embodiment Construction

[0025] 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.

[0026] figure 1 It is a schematic structural diagram of a medical device 100 according to an embodiment of the present invention. The medical device 100 is, for example, a vascular interventional instrument. The medical device 100 includes a moving part 102 , a sensor 106 and a speed limiter 109 . The medical device 100 may also include an examination couch 104 . When the moving part 102 is moving, it may collide with the examination table 104 or the object under examination on the examination table 104, so it needs to be detected before the collision.

[0027] The sensor 106 is disposed on the moving part 102 and forms a field 108 along a moving direction A of the moving part 102 . Field 108 has a boundary 107 . Field 108 may be formed by one or a plurality of sensors 106 . figur...

Abstract

The invention discloses a medical apparatus. According to one embodiment of the invention, the medical apparatus comprises a motion part, at least one sensor and a speed limiter, wherein the at least one sensor is arranged on the motion part and forms a field along one motion direction of the motion part, the field has one boundary, and when an object is positioned on a plurality of points between the boundary and the sensor, the sensor sends a signal relevant to the distance between the point and the sensor; the speed limiter is used for limiting the motion speed of the motion part according to the signal. According to the medical apparatus, the field formed after the object enters the sensor can be detected, and the speed of the motion part is adjusted correspondingly, so that collision is avoided, therefore, the operational safety is greatly improved, and the user experience is improved. The technical scheme is simple, and the cost is low.

Description

technical field [0001] The present invention relates to collision prevention. Background technique [0002] Many medical devices have a moving part that may collide with a subject, examination table, or other object while in motion. In the prior art, some use a pre-established 3D model to dynamically calculate the distance between the moving part and other parts, some use a protective cover, and some use a sensor to detect the occurrence of a collision. [0003] However, unexpected objects may be encountered during the travel of the moving part. Alternatively, pre-built 3D models may be lost when the system malfunctions or is mishandled. Contents of the invention [0004] In view of this, the present invention proposes a medical device. [0005] According to an embodiment of the present invention, a medical device is provided, comprising: a moving part; at least one sensor, which is arranged on the moving part and forms a field along a moving direction of the moving par...
