Description

Animal ear tissue sampling forceps

Technical Field

The utility model relates to an animal ear tissue sampling is with ear number pincers field, in particular to animal ear tissue sampling pincers.

Background

As animal research requires, it is common to collect animal ear tissues for genetic testing or to construct ear tissue fibroblast cell lines. The traditional sampling of animal ear tissues is realized by using an ear clamp for cutting ear notches. However, the ear size pliers are mainly used for cutting ear notches when animals are young, the pliers heads of the ear size pliers cannot be replaced, the sampling size of the used ear size pliers is limited, and sometimes the ear size pliers need to be repeatedly cut for several times to meet the requirements of scientific research, but the ear size pliers cause multiple wounds to the animals and easily cause stress response of the animals; and the general ear clamp does not have the design of connecing the appearance groove, and the ear tissue of cutting will drop easily from the pincers carelessly and cause the pollution at one time, influences the use of ear tissue, and such ear clamp is very inconvenient in using.

SUMMERY OF THE UTILITY MODEL

In order to overcome foretell technical defect, the binding clip of solving current ear number pincers on the one hand can not be changed into the size that needs, has not satisfied the technical problem that scientific research required, and on the other hand solves current ear number pincers and does not design and connect a kind groove, causes the ear tissue of collection to drop easily and causes the technical problem of pollution, the utility model aims to provide an animal ear tissue sampling pincers is in order to solve above-mentioned technical problem.

In some embodiments, the upper binding clip is provided with a through hole corresponding to the sample receiving groove, so that the ear sample in the sample receiving groove of the lower binding clip can be taken out without loosening the sampling clamp after sampling, and the sampling is convenient to take out.

In some embodiments, the upper forceps head is provided with upper forceps teeth, and the lower forceps head is provided with lower forceps teeth, so that the wound is clamped by the upper forceps teeth and the lower forceps teeth while sampling can play a role in stopping bleeding, and the stress response of the animal is reduced.

In some embodiments, the clamp edge is disposed on the inside of the upper clamp tooth, thereby allowing the sample to fall into the sample receiving slot.

In some embodiments, a reset sheet is arranged between the first forceps handle and the second forceps handle, one end of the reset sheet is fixed on the first forceps handle or the second forceps handle, and when the sampling forceps are toothed, the other end of the reset sheet elastically abuts against the second forceps handle or the first forceps handle, so that the two forceps handles can be automatically unfolded after sampling, and the sampling forceps can be conveniently cleaned or the forceps head of the sampling forceps can be conveniently replaced.

In some embodiments, the first forceps handle or the second forceps handle is movably connected with a fixing ring, and when the sampling forceps are engaged, the other end of the fixing ring can be sleeved on the second forceps handle or the first forceps handle, so that the engagement state is fixed.

In some embodiments, the upper binding clip is provided with scale marks, and the scale marks are arranged on the top or the side wall of the upper binding clip, so that the sampling size can be controlled through the scale marks, and the ear samples with proper sizes can be cut according to the needs of experiments.
