Abstract
The utility model discloses a medical anesthesia instrument, in particular to a parallel type epidural-lumbar anesthesia combined puncture needle, which mainly solves the problems of unreasonableness, poor safety and the like in the CSEA (combined spinal-epidural anesthesia) operation procedure. The parallel type epidural-lumbar anesthesia combined puncture needle comprises an epidural needle (1), a lumbar anesthesia guide cylinder (2) and a movable handle (2), wherein the epidural needle (1) and the lumbar anesthesia guide cylinder (2) are longitudinally and integrally combined, a needle opening of the epidural needle (1) is opposite to a needle opening of the lumbar anesthesia guide cylinder (2), the needle opening of the lumbar anesthesia guide cylinder (2) is 0.8cm to 1.0cm lower than a tip of the epidural needle (1), 1.0cm black zebra stripes are arranged at 1.0cm intervals to mark length for a needle body, a handle groove (4) matched with the movable handle is arranged on a needle grip, and an independent guide cylinder opening (5) is arranged at the back of the needle grip. The parallel type epidural-lumbar anesthesia combined puncture needle is applicable to CSEA, enables an operation procedure of epidural cavity catheterization prior to lumbar anesthesia drug administration, and is more scientific and reasonable.
Description
Technical field
This utility model relates to medical anaesthetic apparatus, exactly is the combined puncturing needle of intravertebral anesthesia, that is: block form epidural-lumbar anesthesia combined puncturing needle.
Background technology
At present, carry out the employed puncture needle of CSEA (CSEA) clinically, all be pin in the pin, epidural needle in " disposable use epidural and lumbar combined anesthetic puncture bag " that its shape and accessory such as Henan Xinxiang Tuoren Medical Appliances Co., Ltd. produce and the eel-like figure that matches fiber crops puncture needle.When using this class combined puncturing needle to carry out CSEA, because epidural catheter and lumbar anesthesia puncture needle all are by same tube chamber, so can only carry out lumbar anesthesia operation earlier, treat that administration finishes to withdraw from after the built-in lumbar anesthesia puncture needle, could carry out the operation that epidural space is put pipe again.When epidural space is put pipe, a series of situations such as pipe difficulty, intravascular epidural catheter placement or subarachnoid space may appear putting, may prolong the later operating time of lumbar anesthesia administration, certainly will incur loss through delay the regulation and control planar best opportunity of lumbar anesthesia, and can not in time monitor and handle effectively, and then there be medical hidden danger or medical tangle takes place patient's vital sign.
Summary of the invention
Existing in order to overcome " pin in the pin " can not put the deficiency of pipe back lumbar anesthesia earlier, this utility model provides a kind of block form epidural-lumbar anesthesia combined puncturing needle, and this combined puncturing needle has been realized inserting the more scientific and reasonable anesthesia program that epidural catheter then carries out the lumbar anesthesia operation earlier.
The technical solution of the utility model is such: i.e. block form epidural-lumbar anesthesia combined puncturing needle is made up of epidural needle, lumbar anesthesia guiding needle tubing and flexible handle.Wherein epidural needle and lumbar anesthesia guiding needle tubing vertically is connected as a single entity side by side, and the pin mouth of the spoon shape pin mouth of epidural needle and lumbar anesthesia guiding needle tubing is opposing, and the pin mouth of lumbar anesthesia guiding needle tubing is apart from the most advanced and sophisticated short 0.8cm～1.0cm of epidural needle; The dorsal part of the seam that can join with syringe at epidural needle handle tail end has the separate openings of lumbar anesthesia guiding needle tubing, and the eel-like figure fiber crops puncture needle in this cover combined puncturing needle assembly can be guided needle tubing through lumbar anesthesia by this mouthful and be thrust subarachnoid space; Whole needle body borrows 1.0cm black zebra-stripe to indicate length separately with 1.0cm; The groove that is complementary with flexible handle is arranged on the needle handle, and this flexible handle assembly can freely be installed according to operator's needs.
The beneficial effects of the utility model are, after the spoon shape otch of this combined puncturing needle needle tip successfully enters the human body epidural space, can by the tube chamber of epidural needle epidural catheter be inserted epidural space earlier, judge successfully and determine that inserting built-in eel-like figure fiber crops puncture needle along lumbar anesthesia guiding needle tubing again after errorless carries out the lumbar anesthesia administration, thoroughly realized putting earlier pipe back lumbar anesthesia, more scientific and reasonable than the operation sequence of CSEA in the past; Because needle body has the black zebra-stripe to indicate scale separately, the degree of depth of easier judgement inserting needle; In addition, can in needle handle portion the flexible handle that becomes vertical with the needle body longitudinal axis be installed freely, more help operation according to operator's needs.
Description of drawings
Accompanying drawing 3 is sketch maps of this utility model block form epidural-lumbar anesthesia combined puncturing needle flexible handle.
Wherein: 1. epidural needle, 2. lumbar anesthesia guiding needle tubing, 3. flexible handle, 4. handle grooves, 5. guid needle tube opening.
The specific embodiment
Shown in accompanying drawing 1,2,3, block form epidural-lumbar anesthesia combined puncturing needle is made up of epidural needle 1, lumbar anesthesia guiding needle tubing 2 and flexible handle 3.Epidural needle 1 vertically is connected as a single entity side by side with lumbar anesthesia guiding needle tubing 2; The pin mouth of the spoon shape pin mouth of epidural needle 1 and lumbar anesthesia guiding needle tubing 2 is opposing, and the pin mouth of lumbar anesthesia guiding needle tubing 2 is apart from epidural needle 1 most advanced and sophisticated short 0.8～1.0cm; Whole needle body borrows 1.0cm black zebra-stripe to indicate length separately with the length of 1.0cm; The handle grooves 4 that is complementary with flexible handle is arranged on the handle of epidural needle 1; Lumbar anesthesia guiding needle tubing passes the dorsal part of epidural needle 1 needle handle and independently guid needle tube opening 5 is arranged.Using method is similar to epidural needle anesthesia procedure method, and operation routinely makes the spoon shape otch of epidural needle 1 enter epidural space, carries out epidural space by epidural needle 1 earlier and puts pipe, and place on one side temporarily the success back; Enter into subarachnoid space by the built-in eel-like figure fiber crops of lumbar anesthesia guiding needle tubing 2 insertions puncture needle again and carry out the lumbar anesthesia administration, treat to pull out immediately after subarachnoid administration finishes built-in eel-like figure fiber crops puncture needle, and then withdraw from epidural needle 1, fix epidural catheter, stand up lie on the back pendulum mass position and regulation and control and test level of anesthesia then, thereby reach purpose more scientific and reasonable on the CSEA operation sequence.
