Description

Hob type biological epidermis dissecting device

Technical Field

The utility model relates to the field of experimental biological dissection, in particular to a hob type biological epidermis dissecting device.

Background

In animal experiments, a large number of experimental samples are collected, and often an animal epidermis is required to be dissected to observe an internal structure or obtain a certain organ of an experimental organism, the biological experimental samples generally need to be provided with a control group and an experimental group, sometimes also comprise an environmental control group, and part of experiments have higher requirements on the activity of the collected samples, so that the dissecting experiments need to be completed quickly. The current traditional operation mode is as follows: the epidermis of the animal is gently lifted near the cloaca by forceps, then an opening is cut by scissors, then the epidermis is lifted forward by forceps, and the skin is slowly cut by scissors until the epidermis of the animal is completely cut open.

The dissection mode is slow in dissection speed and requires a long time, because the internal organs are possibly damaged due to the fact that the internal organs are obliquely inserted into the viscera due to improper angles and depths when the scissors are opened, on one hand, biological resources are wasted, the whole experiment cannot be completed, and on the other hand, ethical problems of experimental animals can be related. This dissection is inefficient and has a high probability of damaging the integrity of the biological sample organ and is not suitable for tests with high collection and a low number of tests.

Heretofore, in the process of collecting animal experimental sample organs, the organ samples of organisms are obtained quickly and completely, especially when the number of experiments is rare or biological samples are difficult to obtain, and success needs to be achieved once, and only using tweezers and scissors is difficult to achieve.

Detailed Description

The utility model will be described in further detail with reference to the drawings and the specific examples.

As shown in fig. 1, the hob type biological epidermis dissecting device comprises a first shear body 1 and a second shear body 2 which are arranged in a crossing manner, wherein the first shear body 1 and the second shear body 2 are hinged. In this embodiment, the first scissors body 1 and the second scissors body 2 are both made of stainless steel.

The one end of first shearing body 1 is provided with blade 3, the second shearing body 2 is close to blade 3 one end and is the pointed end, the second shearing body 2 is close to pointed end department and is provided with the recess 5 with blade 3 complex, recess 5 is rectangular form recess 5 of seting up along the length direction of second shearing body 2, blade 3 cuts into in recess 5 along with the rotation of first shearing body 1.

The blade 3 can be oval or circular, only need satisfy with the second cut body 2 be close to one side be the arc surface can, in this embodiment, the blade 3 is circular, convenient processing, the length of recess 5 is greater than the diameter of blade 3, the diameter of blade 3 is 1.5cm, centre of a circle department is thicker, and the edge is thin and sharp, is convenient for cut open the epidermis, blade 3 is the casting of stainless steel integration.
