The invention discloses an adjustable needle head
assembly for auxiliary analgesia of minimally invasive
local anesthesia, and relates to the field of
medical equipment, the adjustable needle head
assembly comprises three injection cylinders and a sleeving cylinder, the three injection cylinders are all sleeved with connecting hoses, and the connecting hoses are connected with needle heads. It needs to be explained that in the embodiment of the invention, the rotating frame is rotated to drive the three arc-shaped pushing frames to rotate, then the
extrusion pushing frame is made to move to drive the needle head to conduct
anesthesia, scales are arranged on the
extrusion pushing frame, the entering depth of the needle head can be effectively adjusted, a patient cannot directly see the needle head, and the fear of the patient is eliminated; the consistent
puncturing depth can be ensured, so that the same
medicine effect is ensured, and precise
anesthesia is realized; besides, the disinfection rotary drum disinfects the fingers through a plurality of disinfection cotton pieces and is clamped to the palm of the patient through two supporting sliding frames, the situation that the entering depth of the needle cannot meet the requirement due to the fact that the fingers of the patient are bent up and down in the
anesthesia process is avoided, and therefore the needle
assembly is convenient to use and can guarantee the anesthesia effect.
