Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anesthesia puncture fixation device. Background Art

[0002] Epidural anesthesia is the most common type of anesthesia in clinical practice. It refers to epidural space block anesthesia, which is to inject local anesthetics into the epidural space to block the spinal nerve roots and temporarily paralyze the area controlled by them. This is called epidural space block anesthesia, or epidural block for short. At present, epidural anesthesia can be divided into high, middle, low and sacral canal blocks according to the puncture site. During anesthesia, the patient needs to lie on his side on the bed with a medical surgical cloth, holding his knees with both hands, and his head as close to his knees as possible. After the doctor completes the puncture, the puncture needle needs to remain on the patient's spine, and then the anesthetic needle is inserted into the puncture needle for injection.

[0003] The patent with announcement number CN208287060U discloses an anesthesia puncture fixator, including a first fixing plate, a plug-in hole is provided in the middle of the outer wall of the first fixing plate, a sleeve is fixedly connected to the bottom of the first fixing plate, a fixing belt is connected to the side wall of the first fixing plate, an adhesive pad is bonded to the end of the fixing belt away from the first fixing plate, the upper end face of the first fixing plate is fixedly connected to a support rod, a second fixing plate is fixedly connected to the support rod, a groove is provided in the middle of the outer wall of the second fixing plate, a pair of through holes parallel to each other are provided on the second fixing plate, and the through holes are connected to the grooves, a rotating shaft is plugged in the through holes, and a roller is fixedly connected to the rotating shaft. The puncture fixator is bonded to the surface of human skin through the adhesive pad, and the puncture needle is clamped by two rollers. The puncture needle passes through the positioning hole, which plays a role in positioning and maintaining the state of the puncture needle.

[0004] However, the human skin surface has great elasticity. Even if the fixator is bonded to the human skin, it is easy for the fixator to translate and twist with the surface skin relative to the inner muscles, fascia, etc., making it easy for the puncture needle to cause greater damage to the human body.
