The utility model belongs to medical apparatus and instruments, concretely relates to a kind of pathological auxiliary material taking tool of endoscopic mucosal resection specimen, including total connecting plate and comb plate;The side of total connecting plate is connected comb plate;Comb plate is composed of several parallel straight boards, the width of each straight board is less than target material taking width;The distance between the upper edge of the n-1th straight board to the upper / lower edge of the nth straight board is equal to the distance between the upper / lower edge of the nth straight board to the upper / lower edge of the n+1th straight board, and the distance between the upper / lower edge of the n-1th straight board to the upper / lower edge of the nth straight board is equal to target material taking width, wherein, n is natural number greater than 1 and less than total number N.Compared with prior art, the utility model solves the problem that it is difficult to control the cutting size and easy to cause specimen contamination when cutting specimen into mucosal strips in prior art.The tool of the present scheme can effectively assist cutting positioning and control the cutting size.

The invention relates to a construction device and method for construction of unequal-height beam webs through equal-height beam side formworks, and belongs to the technical field of building beam construction.The device comprises a vertical rod with an adjustable bearing, a beam bottom height adjustable early-dismantling jacking, a beam bottom rib, a beam bottom formwork, double joists and the beam side formworks, and the double joists are installed on the vertical rod with the adjustable bearing; the positions of the double joists can be adjusted by adjusting the adjustable bearing vertical rods, the beam side molds are installed on the double joists, the beam bottom height adjustable early-dismantling jacking supports are installed on the double joists, the beam bottom rib and the beam bottom mold are installed on the beam bottom height adjustable early-dismantling jacking supports, and the beam bottom rib and the beam bottom mold are located between the beam side molds. The positions of the beam bottom rib and the beam bottom die can be adjusted by adjusting the beam bottom height-adjustable early-dismantling jacking, and construction of unequal-height beam webs is achieved. According to the construction method, beam side formworks of the same specification can be used for construction of beam webs of different heights, the specifications and models of the beam side formworks can be reduced, the management and storage cost of the formworks can be reduced, and the turnover utilization rate and the construction efficiency of the formworks can be improved.
