Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, this embodiment discloses a biopsy sampling device, including a sampling tube 1, the inside slip of sampling tube 1 is provided with slider 2, slider 2 inside articulates there is sampling rod 3, through setting up slider 2 with the intermediate position department of sampling rod 3, not only can make the reciprocate of sampling rod 3 more convenient, still can utilize lever principle to increase the pressure between barb 6 to tumour tissue when taking a sample, because general hooking device is the direct barb 6 that utilizes through operating sampling rod 3 to hook the tissue, so the force from sampling rod 3 top to bottom is bigger, and then reduce to the pressure of tissue, so be inconvenient for sampling work, and will increase moment after articulated slider 2 in the intermediate part of sampling rod 3, make it convenient for hook tumour tissue, the top of sampling rod 3 is provided with handle 4, handle 4 can be convenient for operate sampling rod 3, the surface of sampling rod 3 is provided with sample connection 5, the bottom of sampling rod 3 is provided with barb 6, in the work of operating the tissue sample, the barb 5 is aimed at to the barb connection of barb 6.

Preferably, the surface of the sampling tube 1 is slidably provided with a fixing tube 8, the bottom end of the fixing tube 8 is provided with a fixing ring 9, and the fixing ring 9 is used for being stuck to the superficial skin, so that the depth of the sampling tube 1 inside the fixing tube 8 entering the skin can be seen.

Preferably, the inside of fixed section of thick bamboo 8 is provided with first stopper 11, and the surface of sampling tube 1 is provided with second stopper 10, and first stopper 11 and second stopper 10 intermesh, and when first stopper 11 did not mesh with second stopper 10, sampling tube 1 just can slide from top to bottom in the inside of fixed section of thick bamboo 8, and when first stopper 11 and second stopper 10 intermesh, sampling tube 1 just can not slide from top to bottom in the inside of fixed section of thick bamboo 8 to can fix the degree of depth that sampling tube 1 stretched into tumor tissue.
