Description
Technical Field
The utility model relates to the field of medical equipment, in particular to facial muscle needle.
Background
Botulinum toxin, a toxin produced by botulinum bacteria, a neurotoxin, was originally used to treat facial muscle spasms and other muscle motor disorders, to paralyze the muscle nerves for the purpose of stopping muscle spasms, and was subsequently used in medical cosmetics. The botulinum toxin can block nerve impulse between nerves and muscles, so that excessively contracted small muscles are relaxed, and the effect of removing wrinkles is achieved. Or the muscle can be temporarily paralyzed by the characteristic of the muscle, so that the muscle is atrophied due to the loss of function to achieve the purpose of sculpting lines, namely removing wrinkles and thinning the face.
The myoelectricity guided injection of the botulinum toxin determines target muscles according to myoelectricity feedback in the treatment process, one end of a needle head is connected with a myoelectricity recorder, and exciting muscles can be reflected from the aspects of myoelectricity graphs and audio. During the injection process, the patient actively moves related muscles, correct needle insertion muscles are determined according to the electromyographic signals, and after the target muscles are determined, the injector is fixed, and the botulinum toxin is accurately injected.
The existing facial muscle needle has the defects that after the facial muscle needle is punctured into facial tissues, a doctor cannot easily determine the direction of the inclined plane at the front end of the needle body, and the operation of rotating the facial muscle needle is inconvenient.

Description of the symbols: needle body 1, lumen 2, inclined plane 3, needle stand 4, body 5, needle wing 6, inner hole 7, opening 8, needle hole 9, lead wire 10, sizing material 11, handheld portion 12, connecting portion 13, terminal 14
Detailed Description
Referring to fig. 1, the facial muscle needle of the present disclosure includes a needle body 1, a needle seat 4 and a connecting line 10.
Referring to fig. 1 and 2, a lumen 2 is formed in a needle body 1, a bevel 3 is formed at the front end of the needle body 1, and an insulating coating is formed on the outer surface of the needle body 1. The insulating coating may be a teflon coating. The Teflon coating has good biocompatibility and smooth surface, and is beneficial to the facial tissues of a human body to be penetrated by a facial muscle needle.
The needle body 1 is made of medical stainless steel, the front end of the needle body forms an inclined plane 3, the sharpness of the front end of the needle body 1 is enhanced by the inclined plane 3, and the needle body 1 can conveniently pierce muscle tissues. The insulating coating is coated on the outer surface of the needle body 1, plays an insulating role, and prevents that electromyographic signals of non-target muscles form interference signals by being collected through the outer surface of the needle body 1 in the process of searching the target muscles. The inclined plane 3 of the needle body 1 has no insulating coating, and the myoelectric signals of the target muscles are collected through the inclined plane 3.
Referring to fig. 1, the needle holder 4 includes a body 5 and a needle wing 6 disposed at one side of the body 5. In some embodiments, referring to fig. 1 and 2, the needle wing 6 is located in a plane parallel to a plane normal to the bevel 3 through the central axis of the needle body 1. In some embodiments, referring to fig. 4, the needle wing 6 is located on a plane perpendicular to a normal plane of the bevel 3 passing through the central axis of the needle body 1.
The needle wing 6 is specially arranged on the side surface of the needle seat 4, and the needle wing 6 can assist a doctor to judge the direction of the inclined plane 3 at the front end of the needle body 1 and is convenient for the doctor to rotate the facial muscle needle. When the plane of the needle wing 6 is parallel to the normal plane of the inclined plane 3 passing through the central axis of the needle body 1, the direction of the inclined plane 3 is parallel to the direction of the plane of the needle wing 6. Furthermore, the plane of the needle wing 6 is parallel to the normal plane of the inclined plane 3 passing through the central axis of the needle body 1, the orientation of the needle wing 6 corresponds to the orientation of the inclined plane 3, and the orientation of the needle wing 6 is the orientation of the inclined plane 3. When the plane of the needle wing 6 is vertical to the normal plane of the inclined plane 3 passing through the central axis of the needle body, the direction of the inclined plane 3 is vertical to the needle wing 6.
Referring to fig. 2 and 3, the body 5 has an inner hole 7 therein, an opening 8 of the inner hole 7 is formed at the rear end of the body 5, the front end of the needle body 1 has a needle hole 9 communicating with the inner hole 7, and the rear end of the needle body 1 is inserted into the needle hole 9.
Further, the body 5 comprises a handheld part 12 and a connecting part 13 arranged at the front end of the handheld part 12, wherein the handheld part 12 is internally provided with an inner hole 7, and the connecting part 13 is internally provided with a pinhole 9.
