Ultrasonic-guided nerve block puncture needle with external guiding mechanism

Abstract

The invention provides an ultrasound-guided nerve block puncture needle with an external guiding mechanism, and relates to the technical field of needles, the ultrasound-guided nerve block puncture needle comprises a needle body and a guiding device, one end of the needle body is sleeved with an infusion tube, the guiding device is located on one side of the needle body, the guiding device comprises a positioning piece and a magnetic sheet, the positioning piece is arranged on the needle body in a sleeving mode, the inner wall of the positioning piece is rotationally connected with a limiting ball, a sliding hole is formed in the surface of the limiting ball, and the needle body penetrates through the sliding hole and is in sliding connection with the inner wall of the sliding hole. By arranging the guiding device, the angle position of the needle head can be conveniently adjusted, the situation that most traditional puncture needles are used only in an inserting mode, fine adjustment is difficult to conduct on the puncture needles in the using process, and the positions are mistakenly punctured easily is avoided, then the failure rate of an operation is reduced, potential safety hazards of the operation are reduced, and the usability of equipment is improved; and normal use of equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of needles, in particular to an ultrasound-guided nerve block puncture needle with an external guiding mechanism. Background technique [0002] Needle is a kind of slender tool used for sewing clothes thread. One end of the needle is sharp. Most of the needles are metal products, which are often used in production and life. [0003] Puncture needles are often used to detect the physical condition of patients. Most puncture needles are only used by inserting them. It is difficult to fine-tune them during use and prone to wrong positions, which will increase the failure rate of operations and increase the safety hazards of operations. , reducing the ease of use of the equipment, which is not conducive to the normal use of the equipment. In the existing patent connection solutions, some puncture needles are positioned by magnet adsorption. Fixer, but this kind of scheme can only realize the insertion pin in th...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that most of the puncture needles in the prior art are only used by inserting them, and it is difficult to fine-tune them during use and easily cause wrong positions, thereby increasing the failure rate of the operation and increasing the cost of the operation. Potential safety hazards, reducing the ease of use of the equipment, and the disadvantages that are not conducive to the normal use of the equipment, and a kind of ultrasound-guided nerve block puncture needle with an external guiding mechanism is proposed
