[0002] Under the current trend, electroacupuncture therapy is developed on the basis of traditional Chinese medicine acupuncture therapy. It is an operation technique that uses a combination of needle and electrical stimulation to prevent and treat diseases by inserting needles into acupoints to obtain qi and then passing a trace low-frequency pulse current close to human bioelectricity through the needles.

[0003] Electroacupuncture is widely used in clinical internal medicine, surgery, gynecology, dermatology, ophthalmology, ENT, orthopedics, etc.

The common way to implement electroacupuncture intervention experiments on small animals is: the commonly used electroacupuncture instrument is mainly connected in a way that the metal wire of the output electrode is clamped at the needle handle. The main problems are: small animals have dense hair, and during electroacupuncture intervention experiments, the metal clamps may appear due to the unexpected movements of the small animals, causing the needle to deform and changing the insertion depth, making it impossible to achieve the experimental purpose, and even causing the needle to break, endangering the safety of the animals.

[0073] The electroacupuncture instrument 1 is an existing instrument, which mainly provides acupuncture current for single needle intervention;

[0074] There are many types of small animal fixing plates 2 in the prior art, and the main purpose is to fix the small animal through the buckles or straps on the small animal fixing plates 2;

[0075] In this technical solution, the following are provided:

[0076] A plurality of side brackets 10 are arranged at the edges of the length side of the small animal fixing plate 2 so that a small animal fixing space 3 is reserved above the small animal fixing plate 2;

[0095] The designed conductive metal sheet 206 can keep the wire clamp 221 in good contact while avoiding the influence on the puncture needle 210 and the connecting wire 224, and facilitate the connection. At the same time, it avoids the influence of the wire clamp torque on the needle position, so that the needle is in place and the acupuncture depth is fixed during the experiment.

[0096] During the experiment, the needle portion 210 can be prevented from being bent or even pulled out by the torsion force of the wire clamp, which facilitates the experimental operation.

[0097] In a more preferred embodiment, the needle body of the puncture needle 210 is 13 mm in length and 0.16 mm in diameter, and is preferably made of austenitic stainless steel, which is more suitable for acupuncture intervention in small experimental animals.
