Abstract
The utility model discloses a kind of for pin sting device in the pin of ultrasonic guidance combined spinal-epidural anesthesia, it comprises anesthesia spinal needle and lumbar anaesthesia puncture needle, the inside of described anesthesia spinal needle is axially arranged with along it passage running through its two ends, and the needle tubing of described lumbar anaesthesia puncture needle is placed through in the passage of anesthesia spinal needle inside; The outer surface of the needle tubing of described lumbar anaesthesia puncture needle is respectively equipped with fluorescence coating, and this fluorescence coating is provided with the graduation mark that scale division value is 1mm.This utility model can really develop under ultrasonic visualization, and millimetre-sized graduation mark is more accurate to practical operation, and realize Wicresoft more, clinical efficacy is protected more simultaneously, and risk is less, and security performance is better.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly a kind of for pin sting device in the pin of ultrasonic guidance combined spinal-epidural anesthesia.
Background technology
The method of combined spinal-epidural anesthesia is: be first used alone anesthesia spinal needle and carry out epidural puncture, success backed off after random anesthesia spinal needle inner core, lumbar anaesthesia puncture needle is inserted in anesthesia spinal needle and enters, have after breaking through sense and stop entering lumbar anaesthesia puncture needle, exit lumbar anaesthesia puncture needle inner core, observe after having cerebrospinal fluid to flow out and lumbar anesthesia medicine is injected subarachnoid space by lumbar anaesthesia puncture needle, after exiting lumbar anaesthesia puncture needle, insert epidural catheter through anesthesia spinal needle, finally exit anesthesia spinal needle.
Localization by ultrasonic and ultrasonic guidance carry out the new technique that combined spinal-epidural anesthesia, lumbar anesthesia and epidural anesthesia (being collectively referred to as intravertebral anesthesia) are the regional anesthesiies occurred in recent years, it carries out visual puncture and injection of medicine anesthesia to intraspinal tube under the real time monitoring of ultrasonoscopy, and finishing drilling than traditional non-direct-view substantially increases safety and accuracy.In the pin of ultrasonic guidance combined spinal-epidural anesthesia, pin puncturing kit comprises anesthesia spinal needle and lumbar anaesthesia puncture needle, the inadequate refinement of anesthesia spinal needle scale, more can not ultrasonic development; Lumbar anaesthesia puncture needle, can not ultrasonic development without scale.These all can not embody visual anesthesia procedure requirement and the epoch substitute, and also occur without this series products on the market at present.Clinical practice application encounters very large difficulty, be badly in need of the anesthetic puncture external member of refinement scale, ultrasonic development, urgent needs clinical practice product can come out early, as far as possible for ultrasonic refer to intravertebral anesthesia operation material premise and application foundation are provided, be the healthy service of broad masses.
Summary of the invention
In order to solve deficiency of the prior art, it is simple, easy to use that the purpose of this utility model is to provide a kind of structure, really realizes visual, operates safer for pin sting device in the pin of ultrasonic guidance Wicresoft lumbar anesthesia.
For achieving the above object, this utility model is by the following technical solutions:
A kind of for pin sting device in the pin of ultrasonic guidance combined spinal-epidural anesthesia, comprise anesthesia spinal needle and lumbar anaesthesia puncture needle, the inside of described anesthesia spinal needle is axially arranged with along it passage running through its two ends, and the needle tubing of described lumbar anaesthesia puncture needle is placed through in the passage of anesthesia spinal needle inside; The outer surface of the needle tubing of described lumbar anaesthesia puncture needle is provided with the first fluorescence coating, and this first fluorescence coating is provided with graduation mark.
The scale division value of the graduation mark on described first fluorescence coating is 1mm.
The outer surface of the needle tubing of described anesthesia spinal needle is provided with the second fluorescence coating, and this second fluorescence coating is provided with the graduation mark that scale division value is 1 mm.
The length of the needle tubing of described lumbar anaesthesia puncture needle is 110-115mm.
The length of the needle tubing of described anesthesia spinal needle is 70-80mm.
This utility model adopts above technical scheme, the beneficial effects of the utility model are: this utility model arranges fluorescence coating respectively at the needle tubing of lumbar anaesthesia puncture needle and the needle tubing of anesthesia spinal needle, thus can really develop under ultrasonic visualization, millimetre-sized graduation mark is more accurate to practical operation, realize Wicresoft more simultaneously, clinical efficacy is protected more, and risk is less, and security performance is better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details:
Fig. 1 is a kind of structural representation for pin sting device in the pin of ultrasonic guidance combined spinal-epidural anesthesia of this utility model;
Fig. 2 is the schematic diagram of this practical middle lumbar anaesthesia puncture needle.
Detailed description of the invention
As shown in Figure 1 or 2, this utility model comprises anesthesia spinal needle 1 and lumbar anaesthesia puncture needle 2, the inside of described anesthesia spinal needle 1 is axially arranged with along it passage running through its two ends, and the needle tubing 21 of described lumbar anaesthesia puncture needle 2 is placed through in the passage of anesthesia spinal needle 1 inside; The outer surface of the needle tubing 21 of described lumbar anaesthesia puncture needle 2 is provided with the first fluorescence coating (not shown), and this first fluorescence coating is provided with graduation mark 22, and the scale division value of this graduation mark 22 is 1 mm.
The outer surface of the needle tubing 11 of described anesthesia spinal needle 1 is provided with the second fluorescence coating (not shown), and this second fluorescence coating is provided with the graduation mark 12 that scale division value is 1 mm.
The length of the needle tubing 21 of described lumbar anaesthesia puncture needle 2 is 110-115mm.
The length of the needle tubing 11 of described anesthesia spinal needle 1 is 70-80mm.
In this utility model, the specification of anesthesia spinal needle 1 is 16G, and the specification of lumbar anaesthesia puncture needle 2 is 25G.
Operation principle of the present utility model: first utilize the ultrasonic intervertebral space to puncture to position.Under ultrasound guidance, first be used alone anesthesia spinal needle 1 and carry out epidural puncture, the nook closing member of success backed off after random anesthesia spinal needle 1, then adopt pin sting device in pin of the present utility model, lumbar anaesthesia puncture needle 2 is penetrated in anesthesia spinal needle 1 and enters, when meeting breakthrough sense, exit the nook closing member of lumbar anaesthesia puncture needle 2, cerebrospinal fluid flows out, and then local anaesthetics injects subarachnoid space by lumbar anaesthesia puncture needle 2, exits the rear conventional Epidural catheterization of lumbar anaesthesia puncture needle 2.
Based on above-mentioned, this utility model in use, combined spinal-epidural anesthesia is carried out in localization by ultrasonic with under guiding, can develop in conjunction with anesthesia spinal needle 1 and lumbar anaesthesia puncture needle 2, really realize visualized operation, and accurate Calculation can arrive intraspinal distance (as 32 millimeters, being accurate to grade), reduce number of operations and damage.Not only to the patient of old people, pregnant and lying-in women, obesity and lumbar vertebral injury history advantageously.
