Epidural puncture needle insertion device and method for department of anesthesiology

Abstract

The invention discloses an epidural puncture needle insertion device for a department of anesthesiology. The epidural puncture needle insertion device comprises a fixed plate, wherein the two ends ofthe top surface of the fixed plate are fixedly connected with the same handheld U-shaped handle, a pusher bar motor is fixedly mounted on the top surface of the fixed plate, a telescopic end of the pusher bar motor penetrates through the fixed plate in a sliding manner and is fixedly connected with a needle insertion shell, both ends of the bottom surface of the fixed plate are fixedly connected with two fixed rods, compression springs sleeve the fixed rods in a sliding manner, two driving plates are mounted on the two fixed rods in a sliding penetrating manner, and the other end of each of the two driving plates is fixedly connected with the sidewall of the needle insertion shell. According to the epidural puncture needle insertion device, the handheld U-shaped handle is held by a hand, then, a sucker is sucked to skin, and then, a needle insertion region is determined, so that the stability of a puncture needle can be guaranteed, and the aching feeling of a sufferer can be reduced; and when an airbag is deflated, needle insertion is stopped, and a catheter is inserted into the puncture needle, so that a puncture result is convenient to monitor, and whether puncture is successfulor not can be known rapidly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a needle insertion device and method for epidural puncture in the department of anesthesiology. Background technique [0002] Epidural anesthesia (epidural puncture surgery) refers to epidural space block anesthesia, that is, local anesthetic is injected into the epidural space to block the spinal nerve root and temporarily paralyze the innervated area, which is called epidural space block. Delayed anesthesia, referred to as epidural block. According to the way of administration, it can be divided into single method and continuous method. According to the puncture site, it can be divided into high, middle, low and caudal block. [0003] At present, in the operation of epidural puncture, it is necessary to puncture the beveled needle of the puncture needle nearly parallel to the ligamentum flavum or keep an angle constant to the ligamentum flavum, and then place a non-resistance s...

Problems solved by technology

[0004] Epidural puncture surgery is very difficult, and beginners are likely to cause pain to the user due to lack of experience, which may cause pain to the user, or damage the skin tissue due to the shaking or twisting of the hand of the medical staff when inserting the needle, and The strength of the above techniques requires many years of experience to master, and beginners are prone to too many medical accidents
