Description

Medical same core pin electrode

Technical field

The utility model technology is related to the field of medical instrument technology, specifically discloses a kind of medical same core pin electrode.

Background technique

Common same core pin electrode wears a metal internal thread at needle tubing center, interior wire material is nichrome, silver, white Gold or copper, the coating insulation of internal thread outside.Mutually insulated between internal thread, outer tube, is formed into a loop by human muscular tissue.This needle Manufacturing process is complicated, expensive.

Utility model content

It is reasonable in design the purpose of the utility model is to provide a kind of medical same core pin electrode, it is easy to operate, can Lean on, improve the accuracy of signal acquisition.

To achieve the goals above, the utility model uses technical solution below: a kind of new medical is electric with core needle Pole, including handle, the intracavity of handle are equipped with copper plug and bracket, and the bracket connects outer needle tubing, in the copper plug connects Needle tubing, the intracavity of handle are additionally provided with the plug slot of the fixed copper plug and the partition wall of the fixed bracket, the outer needle tubing Side is equipped with needle core.

Further, the handle is by ABS material one-pass molding.

Further, the needle core is made of medical stainless steel material.

Further, the needle core surface is coated with polyurethane insulating layer.

The utility model has the beneficial effects that: intracavity of handle devises the plug slot of fixed copper plug and support bracket fastened Copper plug and bracket fixation are effectively allowed to not vibration by partition wall in the handle, and structure is simple, and effect is good；Needle core is using doctor With stainless steel material, needle core insulation uses polyurethane material, and polyurethane is good with stainless steel adhesive force, cheap, manufacturing process Simply, insulation performance is high.
