Description
Technical field
The present invention relates to medical anaesthetic apparatus fields, refer in particular to a kind of indwelling tube and guide ultra-fine needle ubarachnoid block
Sting device and its application method.
Background technology
Ubarachnoid block abbreviation lumbar anesthesia is the common anesthesia method of lower abdominal surgery, it has analgesia complete, works
Rapidly, flesh pine is fully and expense is low, restores the features such as fast, but headache, lumbago and nervous lesion are more typically concurrent after lumbar anesthesia
Disease.Original lumbar anaesthesia puncture needle enters cavum subarachnoidale using the sharp angle needle Direct perforantes that are open mostly, on the one hand, this is worn
Pricker eyelet great Yi causes cerebrospinal fluid largely to be oozed out at pinprick, and patient's Headache probability is higher, on the other hand, the puncture needle needle
Body is very thick, and the damage of ligament and subcutaneous tissue to back etc. also easily leads to the postoperative lumbago of patient, and sharp keen needle point is anti-
The cauda equina nerve of patient and intervertebral foramen nerve are easily damaged in multiple puncture process.Before, there are some knockdown waists on the market
Numb sting device design, such as a kind of needle for the minimally invasive lumbar anesthesia of ultrasonic guidance disclosed in Chinese patent 201420529070.1
Interior pin puncture device, includes skin-dilating needle and lumbar puncture needle, and expansion skin guiding inserting needle is carried out as skin-dilating needle using the injection needle of 20G
It explores the way, then using needle technology in needle, skin-dilating needle is passed through to carry out cavum subarachnoidale puncture lumbar puncture needle, however, this use 20G
Injection needle carries out expansion skin guiding inserting needle as skin-dilating needle and explores the way, and the needle tubing of 20G injection needles is thicker, similary easily damage in puncture process
Hinder the back ligament and subcutaneous tissue of patient, due to using ultrasonic guidance, the financial burden of patient is increased, so that not
Use is popularized convenient for base.Now also there is improvement to replace needle body with a kind of the remain silent ultra-fine puncture needle of ball pen wick-like of front end on the market
Angle needle relatively thick, opening is sharp, during puncture, without using ultrasonic guidance, can also greatly reduce the fibre of patient
The tissue damages such as ligament, and the basic loss without cerebrospinal fluid are tieed up, but ultra-fine puncture needle, since needle body is thin, itself supports hardness
Not enough, front end round blunt it is not sharp it is more difficult puncture skin, when puncture, is difficult to control direction, easily causes needle body bending deformation, even
Puncture needle is broken, and leads to puncture failure so that punctures time lengthening, and then the damage of bigger is caused to patient.
Invention content
Present invention deficiency existing for the above-mentioned prior art, main purpose are that providing a kind of indwelling tube guides ultra-fine needle
The sting device and its application method of ubarachnoid block solve existing 20G injection needles and are punctured as skin-dilating needle in lumbar anesthesia
In the process, occur after spinal anesthesia in patients, the problem of the more typical complication such as headache, lumbago and nervous lesion；Ultra-fine puncture needle exists
In puncture process, when puncture, is difficult to control direction, and needle body is yielding, easily causes asking for puncture failure even puncture needle fracture
Topic.
To realize above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of indwelling tube guides the sting device of ultra-fine needle ubarachnoid block, including indwelling tube, puncture needle and ultra-fine
