Description

Locating puncture needle
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a locating puncture needle.
Background
An autologous arteriovenous fistula is one of the vascular access for hemodialysis treatment of patients with End-stage renal disease (End-StageRenalDisease, ESRD, uremia). Vascular access is the route by which blood in a patient is continually drawn outside the body and returned to the body.
Autologous arteriovenous fistulae have been widely accepted as the first vascular access in uremic patients undergoing maintenance hemodialysis treatment. The buttonhole puncture method is the most effective method for preventing internal fistula hemangioma at present, and the blunt needle buttonhole puncture method is to puncture according to the same needle insertion point, the same angle and the same needle insertion depth every time so as to form a subcutaneous tunnel, namely a buttonhole, and the sharp needle is changed into the blunt needle puncture after the tunnel is formed, and the puncture is carried out along the tunnel.
The blunt needle has a needle tip with a cutting method different from that of a common internal fistula needle, and the blunt needle tip is not provided with a sharp knife, which is designed specifically for buttonhole puncture. After the "tunnel" of the patient's internal fistula puncture site is formed, the puncture can be made using a blunt needle, and the nurse simply twists gently along the "tunnel". In addition, the blunt injury to blood vessels is small, and blood seepage is difficult.
However, the key point of the "buttonhole" puncture method is to require the patient to fix the position, puncture the same puncture point, the same puncture angle and the same depth. Because of the high puncture requirement, the same operator needs to be fixed in actual operation, and the tunnel is estimated to be formed at the same angle and the same depth according to personal operation habits. However, the binding relationship between the patient and the puncture outfit is difficult to achieve in practical work. After the formed tunnel is replaced by a puncture person, a new puncture person can hardly grasp the puncture angle and the puncture depth during puncture, and once the puncture angle and the puncture depth deviate, the puncture failure or the original tunnel can be damaged to form a false tunnel, so that the puncture difficulty is further increased, and the pain of a patient is increased.
