Description

Technical Field

[0001] The utility model relates to the technical field of small insect tissue and organ dissection, and more specifically, to a small insect organ dissection and tissue collection device. Background Art

[0002] Insects are the most numerous animal group on Earth, and many studies on insects require dissecting insects to obtain insect organs or tissues for research. Existing insect tissue and organ dissection forceps or dissection needles are difficult to meet the needs of rapid dissection and collection during the large-scale dissection of small insect tissue and organs. When a large number of small insect tissue samples are collected, the existing dissection needles or dissection forceps can only collect a limited amount of tissue at a time, and the tissue is easy to adhere to the needle arm and is difficult to obtain or damaged. Specifically, in the dissection of small insects, it is usually necessary to directly use forceps to pull the tissue out, and then use the tip of the forceps to groove the tissue. However, in this process, slender tissues such as the intestines are easily entangled on the pointed wall of the forceps, and when transferred to the collected centrifuge tube, they stick to the forceps arm and cannot be removed. Sometimes, they need to be stirred back and forth in the centrifuge tube, or rubbed against the wall of the centrifuge tube, which will damage the tissue. Summary of the invention

[0006] The connecting rod of the small insect organ dissection and tissue collection device of the utility model is a handheld part, and the forked branched dissection fork at one end of the connecting rod is convenient for quickly forking and forking the insect epidermis to decompose the internal tissue. The forked design dissection needle can quickly fork out the internal tissue of the insect in large quantities, improve the dissection speed, and perform batch dissection. At the same time, the fork design can quickly gather the dissected insect tissues together for subsequent rapid collection; the collection shovel at the other end of the connecting rod is convenient for quickly collecting the insect tissues dissected by the dissection fork in batches, which greatly improves the batch dissection and collection speed of small insect samples. Thereby meeting the needs for dissection speed and collection in the process of dissecting a large number of small insect tissues and organs. At the same time, the collection shovel is used to collect and transfer insect tissues, which can avoid the damage to the insect tissues caused by the existing dissection forceps or dissection needles during the transfer process. The small insect organ dissection and tissue collection device of the utility model has a novel structure, a simple structure, easy operation, convenience and practicality, and can be applied to the rapid dissection and batch collection of various types of small insect intestinal, ovarian, fat body and other tissues.
