Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiment:

[0017] Depend on Figure 1 to Figure 3 As shown, the ultrasound-guided peripheral nerve block anesthesia directional puncture device provided by the present invention includes a ring frame 2 arranged on an ultrasonic probe 1, a chain 3 hinged to the ring frame 2 at one end, and a chain 3 arranged at the other end of the chain 3 The clamping device 4 for clamping the anesthesia needle 5 to move within the imaging plane of the ultrasonic probe 1 . The ring frame 2 and the ultrasonic probe 1 are fixedly connected or detachably connected, preferably detachably connected. Specifically, the ring frame 2 is arranged as a clamp structure, and a connecting portion is provided on the clamp, and the connecting portion is connected to the chain 3 hinged. When using the ultrasound-guided peripheral nerve block anesthesia directional puncture device of the present invention, since the c...

Abstract

The invention discloses an ultrasonically-guided peripheral nerve block anesthesia stereotactic puncture device. The ultrasonically-guided peripheral nerve block anesthesia stereotactic puncture device comprises an annular frame, a chain and a clamping device, wherein the annular frame is arranged on an ultrasonic probe; one end of the chain is hinged to the annular frame; the clamping device is arranged at the other end of the chain and is used for clamping an anesthetic needle to move in an imaging plane of the ultrasonic probe. By means of the ultrasonically-guided peripheral nerve block anesthesia stereotactic puncture device, the anesthetic needle is limited by the chain to move in the imaging plane of the ultrasonic probe, thereby solving the problems of high dosage of local anesthetics, prolonging of operation time and the like due to the fact that the anesthetic needle and an ultrasonic wave are not in the same plane.

Description

technical field [0001] The invention relates to a medical device, in particular to an ultrasound-guided peripheral nerve block anesthesia directional puncture device. Background technique [0002] Traditional interscalene brachial plexus block is sometimes ineffective, mostly because the local anesthetic is not injected in the ideal position, resulting in its distribution failing to infiltrate around the nerve tissue. Ultrasound has been used for nerve localization in foreign countries for nearly 20 years. Modern ultrasound technology can almost see the path of the puncture needle and the diffusion and distribution of local anesthetic after injection under direct vision. Anesthesia is performed under ultrasound guidance, and nerves and adjacent structures can be directly seen, and the diffusion of local anesthetic can be seen directly or indirectly when injecting drugs. At present, anesthesiologists hold the ultrasound probe in one hand and the anesthesia needle in the othe...
