An adaptive dissection fixing plate suitable for small animals of multiple sizes

Abstract

This invention relates to the field of anatomical fixation plates, and discloses an adaptive anatomical fixation plate suitable for small animals of various sizes. The plate includes a base, with a placement plate fixedly connected to the top of the base. The top of the placement plate has vertical and horizontal grooves. A trunk fixation mechanism is provided at the bottom of the placement plate, including a motor fixedly mounted on the bottom of the placement plate. A side plate is fixedly connected to the bottom of the placement plate. In this invention, by setting up a trunk fixation mechanism, the motor drives a lead screw to rotate and moves a movable seat horizontally. This is linked by a hinged rod, causing the two moving frames on both sides to move towards each other. Simultaneously, the height of the lifting plate is adjusted synchronously with an electric push rod and a round rod structure, allowing the fixation bar to automatically adapt to the size of the small animal's trunk in both the horizontal and vertical directions. This achieves precise clamping and stable positioning of experimental subjects of different body sizes, significantly improving the versatility and fixation efficiency of the device.
