This invention provides a continuous implantation device for PDX model tumor tissue, comprising: a main cannula; and a pushing component disposed at one end of the main cannula. The continuous implantation device for PDX model tumor tissue provided by this invention utilizes the cooperation of structures such as the main cannula, the pushing component, the tissue sampler, and the retaining spring. The tissue sampler can be pre-loaded with multiple tumor tissue blocks, the retaining spring enables precise positioning and switching of the tissue sampler, the pushing component can sequentially push the tissue blocks for implantation, and the main cannula can be externally connected to an syringe to achieve simultaneous delivery of gel and tissue blocks. This device enables continuous implantation of tumor tissue blocks without the need for repeated clamping and transfer operations, significantly improving implantation efficiency and avoiding the decrease in activity caused by prolonged exposure of tissue blocks outside the body. Furthermore, it eliminates the need for clamping tissue blocks during transfer, reducing the risk of mechanical damage and ensuring the integrity of the tissue blocks. It also enables simultaneous delivery of tissue blocks, gel, and drugs, improving the experimental adaptability of the device.

This utility model discloses a precise collagen implantation device, relating to the field of medical aesthetic device technology. It includes an implantation device with a filling device connected to one end. The precise collagen implantation device of this utility model controls the volume of collagen inside the injection tube by corresponding the movement distance of the moving frame at the bottom of the scale to the scale graduations, improving the accuracy of collagen implantation. A moving motor controls the rotation of a screw, causing the moving frame to drive the piston to move at a constant speed inside the injection tube, ensuring the stability of the collagen implantation speed and automatically replenishing the collagen inside the injection tube, thus improving the efficiency of collagen implantation. By setting a distance sensor to detect the distance between the piston and the positioning plate, the piston moves a fixed distance to the left inside the injection tube, thereby achieving quantitative implantation of collagen in batches. This improves the efficiency of multiple implantations while ensuring accurate implantation volume.
