A tumor sampling device

Abstract

The present invention provides a tumor sampling device, belonging to the technical field of medical instruments, comprising an L-shaped gripping rod and a sliding transmission member. A sliding driving member is slidably mounted on the vertical support-rod section of the L-shaped gripping rod by means of spring biasing. An L-shaped handle rod is welded to the top of the sliding driving member, and the horizontal rod section of the L-shaped handle rod is located above, and arranged close to, the horizontal portion of the L-shaped gripping rod.The sliding transmission member is composed of two upper and lower shaft sleeves of different sizes and two vertical support connecting plates symmetrically welded between the two shaft sleeves. A horizontal guide shaft is welded to the lower side portion of the L-shaped gripping rod, and the upper shaft sleeve is in sliding fit with the horizontal guide shaft. A connecting rod is rotatably connected between the top of the sliding transmission member and the bottom of the L-shaped gripping rod.When the sampling device is in use, tumor tissue sampling can be completed simply by pressing down the L-shaped handle rod 203 by hand and then releasing it. The operation is simple and convenient, effectively improving sampling efficiency.
