Detailed Description
The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a nerve stimulation needle which is beneficial to ultrasonic guidance and is shown in figures 1 and 2, comprising a needle tube 1, a needle core 2, a needle base 3, an extension cord 4, a nerve stimulation instrument interface 5, an extension tube 6, a drug administration joint 7 and a vacuum structure 8; the inside cavity of needle tubing 1 forms the passageway of dosing, needle file 3 is located the tail end of needle tubing 1, nook closing member 2 is located 1 inside of needle tubing, 2 tail ends of nook closing member pass needle file 3, 4 one ends of extension line pass needle file 3 is connected 1 inside lateral wall of needle tubing, the other end is connected neurostimulation appearance interface 5, 6 one ends of extension pipe are passed needle file 3 stretches into 1 inside passageway of dosing of needle tubing, and the other end is connected the joint 7 of dosing.
The utility model discloses a working process is: after the doctor carries out local anesthesia at patient surface skin, will neurostimulation appearance interface 5 connects outside neurostimulation appearance, needle tubing 1 inserts subcutaneous tissue through local anesthesia point, ensures during the insertion the nook closing member 2 extends needle tubing 1 pointed end and synchronous insertion. 0.5-1.5mA current is input from the interface 5 of the nerve stimulator, the current is led into the needle tube 1 through the extension wire 4, when the tip of the needle tube 1 is close to the vicinity of nerve tissue, the current can stimulate the nerve to cause the contraction of muscles, and after a doctor visually observes the surface skin deformation caused by the contraction of the muscles, the doctor can judge whether the needle tube 1 reaches the approximate area required by the operation. At this moment, an ultrasonic device is used for detecting on the body surface, ultrasonic waves can form more ultrasonic reflectors relative to the vacuum structure 8 on the side wall of the needle tube 1, but the ultrasonic waves do not directly penetrate through the vacuum structure 8, so that the developing effect of the vacuum structure 8 on an ultrasonic display instrument is enhanced, a doctor can find linear and equidistantly arranged luminous bodies on the ultrasonic display instrument, the luminous bodies are the vacuum structure 8, the approximate outline of the needle tube 1 can be determined according to the shape formed by the plurality of luminous bodies, and the specific position of the needle tube 1 in the body can be judged by contrasting the image of subcutaneous tissues on the ultrasonic display instrument. After the position of the needle tube 1 is determined, whether the tip of the needle tube 1 is positioned at a nerve tissue is judged, then the needle core 2 can be taken out, medicine is injected from the administration connector 7, and the medicine is conveyed into a human body through the extension tube 6, the needle seat 3 and the needle tube 1 in sequence.
If the side wall of the needle tube 1 is not provided with the vacuum structure, after the needle tube is inserted into the subcutaneous tissue of a human body, a doctor detects the subcutaneous tissue of the human body by using an ultrasonic device, the quantity of reflectors formed on the surface of the needle tube by ultrasonic waves is greatly reduced, so that the image of the needle tube on an ultrasonic display instrument is darker and darker as a whole, the identification degree of the needle tube and the internal tissue of the human body is greatly reduced, and during an operation, the doctor can make a mistake in judging the position of the needle tube and damage the internal tissue of the human body.
Specifically, the whole needle tube 1 is made of metal materials and can be made of stainless steel, the surface of the needle tube 1 is coated with an anti-sticking coating, the anti-sticking coating can be made of Teflon, and the surface of the needle tube 1 is prevented from being stuck with subcutaneous tissues when the needle tube 1 is inserted into or pulled out of human tissues.
In a more specific embodiment, needle tubing 1 lateral wall has the vacuum structure 8 of arranging along axis equidistance, as shown in fig. 4, vacuum structure 8 is the arc cylinder, and vacuum structure lateral wall 82 surfacing is thin layer hard material, can be ya keli, is convenient for vacuum structure 8 embedding needle tubing 1 lateral wall, as shown in fig. 3, vacuum structure bottom 83 orientation that hard material made the passageway one side of dosing is difficult for taking place the deformation, can not influence the needle core 2 is in slide in the needle tubing 1, vacuum structure lateral wall 82 with a flexible piece 81 has still been inlayed to the half cavity that vacuum structure bottom 83 constitutes, and vacuum structure lateral wall 82 glues with flexible piece 81, and flexible piece 81 is inside to have at least one vacuum bubble, wherein atmospheric pressure be less than 0.05MPa can, flexible piece 81 can be silica gel, is convenient for the ultrasonic wave to penetrate and reflect. When the needle tube is inserted into or pulled out of subcutaneous tissue, the flexible block 81 is forced to be concave, and the movement of the needle tube 1 is not hindered. The clearance between the drug administration channel and the needle core 2 is not more than 1mm, so that the needle core 2 is prevented from shaking in the needle tube 1.
Specifically, the tip of the needle tube 1 can be conical, the tip of the needle core 2 can also be conical, and the two tips can be in the same conical surface when matched, so that the needle tube 1 can be more conveniently punctured in subcutaneous tissues.
Specifically, the needle core 2 can be made of a hard material, the needle core is solid inside, after the needle tube 1 is inserted into subcutaneous tissues to reach a designated area, a doctor can take out the needle core 2, then injects medicines into the administration joint 7, the medicines are transmitted into the needle seat 3 through the extension tube 6, and then the medicines are injected into a human body from an internal channel of the needle tube 1.
Specifically, the needle base 3 comprises a shell and a sealing filler in the shell, the shell can be made of plastic, the sealing filler can be made of silica gel, and a pore for the extension line and the extension tube to pass through is formed in the sealing filler. At ordinary times, the pore canal is naturally closed due to the elasticity of the silica gel material, and when the needle core 2 is inserted into the pore canal, the silica gel is propped open when external force is applied. The extension line 4 passes the needle file 3 with the inside lateral wall of needle tubing 1 is connected, extension tube 6 then passes the pore of needle file 3 and stretches into the inside passageway of dosing of needle tubing 1, needle file 3 with the outside seal of needle tubing 1 is good, works as the nook closing member 2 follow the needle tubing 1 is inside takes out the back, the inside colloidal silica of needle file 3 folds closed pore, guarantees by the medicine of extension tube 6 input can not be through the passageway of dosing is followed needle file 3 flows out.
The above is an embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention.
