Tool for rapidly measuring subcutaneous tumor size of mice

Abstract

The invention discloses a tool for rapidly measuring the subcutaneous tumor size of mice. The tool comprises a measurement handle, wherein a limiting adjusting sliding chute is arranged at the upper part of the measurement handle, a measurement slider is mounted on the limiting adjusting sliding chute, an L-shaped forwards extending support arm is arranged at the front side of the measurement slider, a movable measurement clamp is fixed to the forwards extending support arm, a fixed measurement clamp fixed to the measurement handle is arranged at the opposite side of the movable measurement clamp, a row of longitudinal laser range finders is arranged in front of the fixed measurement clamp, a horizontal laser range finder is arranged on the inner wall of the fixed measurement clamp, while the movable measurement clamp and the fixed measurement clamp tightly clamp the subcutaneous tumor of the mice, the longitudinal laser range finders and the horizontal laser range finder respectively calculate the maximal transverse diameter in the vertical direction of the tumor and the maximal diameter in the horizontal direction of the tumor. With the tool, the problems that when a vernier caliper is used for measuring the tumor size in the traditional method, the operation is inconvenient and the data error is large, are solved, in addition, the whole tool is portable and convenient, and the cost is low.

Description

technical field [0001] The invention relates to an experimental tool for inoculating a mouse cell line into a tumor model or transplanted tumor model in oncology-related research, in particular to a rapid mouse subcutaneous tumor volume measurement tool. Background technique [0002] At present, the establishment of mouse subcutaneous cell line inoculation tumor models or xenograft tumor models is a common technical means in oncology-related research. A series of scientific researches have been carried out by observing the growth of mouse subcutaneous tumors. At present, the laboratory observes the growth of subcutaneous tumors in mice mainly through rough measurement and observation of tumor volume. A common method is to use a vernier caliper to record the longest tumor diameter (L) and the largest vertical diameter (W), according to the formula V=LW 2 / 2 to calculate the tumor volume. Although the operation of this method is not difficult, the measurement error is large,...

Problems solved by technology

Although this method is not difficult to operate, the measurement error is large and time-consuming, often requiring the cooperation of two people

In recent years, a tumor tracking system has been developed abroad, which can draw 3D images of tumors within 0.1 seconds and perform calculations. The data accuracy is high and the operation is simple, but the price is very expensive
