Problems solved by technology

During the test, first cut a nerve incision along the length of the nerve bundle, then pick up a part of the nerve bundle with a hemostat or other instruments, then place two hook-shaped electrodes under the nerve bundle, and test the nerve bundle with electricity. Nerve on one side; then, use hemostatic forceps and other instruments to pick up another part of the nerve bundle, and then place two hook-shaped electrodes under the nerve bundle for stimulation. The hemostatic forceps and the nerve bundle should be changed every time the nerve is tested. The position of the stimulator, which brings great inconvenience to the test of the nerve

Embodiment Construction

[0306] Such as Figure 2 to Figure 5 as shown,

[0307] This embodiment provides a test head, including a test head-electrode 1-1,

[0308] There are two pairs of test head-electrodes 1-1.

[0309] Each pair of said test head-electrodes 1-1 has a positive electrode and a negative electrode.

[0310] One positive electrode and one negative electrode in each pair of said test head-electrodes 1-1 are far away from each other.

[0311] One positive electrode and one negative electrode in one pair of test head-electrodes 1-1 are respectively adjacent to one positive electrode and one negative electrode in another pair of test head-electrodes 1-1.

[0312] Various improvements of this embodiment are described in detail below.

[0313] Such as Figure 2 to Figure 5 as shown,

[0314] One positive electrode of one pair of test head-electrodes 1-1 is close to one positive electrode of another pair of test head-electrodes 1-1.

[0315] One negative electrode of one pair of test h...

Abstract

The invention discloses a testing head and a nerve separation tester thereof. The testing head comprises a testing head-electrode; two pairs of test head-electrodes are arranged; each pair of testing head-electrodes is provided with a positive electrode and a negative electrode; one positive electrode and one negative electrode in each pair of test head-electrodes are far away from each other; and one positive electrode and one negative electrode in the pair of test head-electrodes are respectively close to one positive electrode and one negative electrode in the other pair of test head-electrodes. The nerve separation tester comprises the testing head. According to the invention, nerves at two sides in one nerve incision can be tested only by plugging and unplugging once, so that the test operation of the nerves is greatly facilitated. Various testing heads can be produced according to the requirements of different customers. The device can be easily placed in the nerve incision. The conductivity of the electrode can be ensured. The test precision of the test head can be greatly improved. The stability of the testing head can be greatly improved.

Description

technical field [0001] The invention relates to a test component and a test device thereof, in particular to a test head and a nerve separation tester thereof. Background technique [0002] In the prior art, the test head of the nerve separation tester is a pair of electrodes, and the pair of electrodes includes a positive electrode and a negative electrode, and the shape of the positive electrode and the negative electrode is "L"-shaped. During the test, first cut a nerve incision along the length of the nerve bundle, then pick up a part of the nerve bundle with a hemostat or other instruments, then place two hook-shaped electrodes under the nerve bundle, and test the nerve bundle with electricity. Nerve on one side; then, use hemostatic forceps and other instruments to pick up another part of the nerve bundle, and then place two hook-shaped electrodes under the nerve bundle for stimulation. The hemostatic forceps and the nerve bundle should be changed every time the nerve ...
