Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of combined spinal-epidural anesthesia one puncture needle.
Background technology
Combined spinal-epidural anesthesia is the advantage combining lumbar anesthesia and epidural anesthesia, and anaesthetic effect is improved, and improves operating technology level, obtains deep research at home and abroad and applies widely.Current combined spinal-epidural anesthesia puncture instrument has following several method: 1, adopt " in pin pin " method, successively implements lumbar anesthesia injection (SA) and Epidural catheterization (EA) for subsequent use injection; There are the potential misgivings that epidural catheter is strayed into subarachnoid space in this method.2, after first thrusting epidural space with combined spinal-epidural anesthesia puncture needle, again spinal needle is thrust subarachnoid space through combined spinal-epidural anesthesia puncture needle inner chamber and implement lumbar anesthesia, then exit spinal needle and carry out dura mater Puncture Tube again, stand up and regulate lumbar anesthesia plane, in this process when inserting segmental epidural catheter, may occur that the pinprick that conduit stays at spinal dura mater along former lumbar vertebra pin enters subarachnoid space, cause catheter position inaccurate, insert segmental epidural catheter failure time and again, the such as syndrome such as high-order sensation and nervus motorius retardance may be there is in this situation, safety coefficient is low, the mishandling life that even can affect patient.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of combined spinal-epidural anesthesia one puncture needle.
A kind of combined spinal-epidural anesthesia one puncture needle, comprise syringe 1, wherein: from the outlet of described syringe 1, set gradually combined spinal-epidural anesthesia puncture needle needle handle 2 from top to bottom, combined spinal-epidural anesthesia puncture needle needle stand 3, and holding the pin chamber 6 of epidural catheter 4 and lumbar anaesthesia puncture needle 5, described pin chamber 6 is made up of the chamber and lumbar anaesthesia puncture needle pin chamber 7 that are fixed together side by side for placing epidural catheter 4;
Arrange separate infusion hole 21 and infusion hole 22 respectively in the middle part of described combined spinal-epidural anesthesia puncture needle needle handle 2, described combined spinal-epidural anesthesia puncture needle needle handle 2 forms lumbar anaesthesia puncture needle body with described lumbar anaesthesia puncture needle 5;
