Abstract

The invention discloses a special puncture needle for ultrasonic guidance of great auricular nerve block. The special puncture needle comprises a puncture portion, a connecting portion and a needle seat, wherein a sharp end portion is arranged at one end of the puncture portion; the other end of the puncture portion is fixedly connected to the connecting portion; the other end of the connecting portion is fixedly connected to the needle seat; and an axial line of the puncture portion forms a 120-degree included angle with an axial line of the connecting portion. The special puncture needle for the ultrasonic guidance of the great auricular nerve block provided by the invention can better meet the clinical demand of the great auricular nerve block and optimize clinical operations, so as to facilitate clinical anesthetists to efficiently and conveniently implement the ultrasonic guidance of the great auricular nerve block; and meanwhile, puncture trauma and pain can be reduced, and the occurrence rate of such complications as nerve injury, local hematoma and the like can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special puncture needle for ultrasound-guided great auricular nerve block. Background technique [0002] The great auricular nerve arises from the second and third cervical nerves and is the largest branch of the cutaneous branch of the cervical plexus. The great auricular nerve penetrates the deep fascia near the midpoint of the posterior edge of the sternocleidomastoid muscle to the subcutaneous side, passes through the surface of the muscle, runs forward and upward, and divides into 2 to 4 terminal branches below the earlobe, with an average of 3 branches, distributed in the parotid gland, Skin beneath the masseter muscle, earlobe, retroauricle, and mastoid. The body surface projection of the greater auricular nerve is approximately equivalent to the line drawn from the midpoint of the posterior border of the sternocleidomastoid muscle to the root of the earlobe. T...
