Miniature linear sliding platform

The invention relates to the technical field of medical instruments, and discloses a miniature linear sliding platform. The miniature linear sliding platform comprises a sliding platform, a guide sliding rail, a driving assembly and a distance sensor, wherein the guide sliding rail is arranged on the sliding platform in a penetrating manner. The driving assembly is arranged on the sliding platform, and the output end of the driving assembly can be in transmission connection with the guide sliding rail so as to drive the sliding platform to slide along the guide sliding rail, so that the guide sliding rail can play a role in guiding and transmission, use of a middle complex transmission mechanism is avoided, and the overall structure is compact; the size and the weight of the device are reduced, and the miniaturization design of the device is further facilitated. The distance sensor is arranged on the sliding platform and used for detecting the displacement of the sliding platform relative to the guide sliding
