Description

Technical Field

[0001] This utility model relates to the field of sample collection, and in particular to a bone powder sampling device. Background Technology

[0002] In fields such as forensic medicine, archaeology, orthopedic surgery, animal specimen preparation, and biomaterials research, it is often necessary to obtain powdered samples from human or animal bones for DNA testing, isotope analysis, pathological diagnosis, materials science research, or composition determination. Traditional methods of collecting bone powder mainly rely on manual filing, grinding with a grinding wheel, or drilling with a bench drill. These methods share the following common problems.

[0003] Existing collection devices mainly include bone sample collection devices disclosed in application number "CN201420486513.3". These devices use a box, a drill bit, and a bone sample holder to drill and sample bones inside the box. Although the operation inside the box is isolated from the external environment, frequent operation results in a large amount of powder accumulating inside the box, which is difficult to clean.

[0004] Therefore, existing sampling devices mainly face the following challenges:

[0005] 1. Difficulty in positioning and fixing: The bones have complex shapes and varying surface curvatures, making it difficult for conventional clamps to hold them securely. This results in uncontrollable sampling depth and position, and the samples are easily contaminated or mixed with impurities.

[0006] 2. Dust diffusion and cross-contamination: Open-air operations cause bone powder to scatter, which not only endangers the health of operators, but also easily leads to cross-contamination between different samples, affecting subsequent test results;

[0007] 4. Its structure is large and complex, making it difficult to move.

[0008] 3. Cumbersome and inefficient operation: Frequent changes of fixtures, cleaning of the site, and collection of powder result in many operation steps and long operation time. Utility Model Content
