The invention relates to a tissue specimen processing system, including a specimen liquid distributor. The specimen liquid distributor includes a support frame and a liquid barrel provided at the upper part of the support frame, wherein, the liquid barrel includes a hollow barrel, a filling opening provided at the upper part of the hollow barrel, as well as a liquid taking mouth with a liquid taking switch provided at the lower part of the hollow barrel. Specimen fluids and solvents can be directly injected into the liquid barrel for configuration, can be centrally configured in proportion toensure the concentration accuracy; when in use, it is only needed to place the specimen bag below the liquid taking mouth, opening the liquid taking switch to discharge the specimen liquid, which haseasy operation, convenience, easy spraying; and as the disinfecting liquid is concentrated in the liquid barrel, which has good sealing effect and stable concentration because the volatilization of the specimen liquid is furthest reduced. In addition, the specimen can have centralized management by placing the specimen bag in the checking vehicle, which can perform effective management to the specimen, to facilitate the transfer, and is convenient, time-saving, and safe.
