Abstract

The utility model relates to an anesthesia puncture needle for brachial plexus nerve block, which is composed of a needle rod, a handle and a PVC extended pipe, wherein the handle is fixed to the rear end of the needle rod. One end of the PVC extended pipe is connected with the tail end of the needle rod, and the other end is provided with an interface connected with an injector. The side on the front end of the needle rod is provided with a liquid outlet bore, and the needle rod is provided with graduations. Because a liquid outlet bore is arranged in the side of the front segment of the needle rod, the injected physic liquor can be simultaneously injected into the reserved anesthesia position from a needle point and a side liquid outlet bore so as to enhance the anaesthetic effect. The graduations arranged on the needle rod can directly show the depth of puncture and the position of the needle point and raise the accuracy of the puncture. The handle with dual wings, which is arranged on the tail end of the needle, brings convenience for operation and fixing. The PVC extended pipe separating the puncture needle from the injector is helpful for accurate puncture and injection. Meanwhile, the character of pumped liquid can be observed and authenticated by the transparent PVC extended pipe to prevent full spinal anesthesia and partial anesthesia poisoning which are caused by the misinjection of partial anesthesia into a subarachnoid cavity or blood vessels.

This utility model relates to a kind of medical instruments, relates in particular to a kind of anaesthetic puncture needle.

Background technology:

Brachial plexus nerve is by neck _5～8And breast ₁The preceding Zhi Zucheng of spinal nerves, it is the mixed nerve of whole upper extremity exercise of domination and sensation.Adopt brachial plexus nerve block can make upper breast, shoulder joint, upper limb obtain good anesthesia, for the operation of above-mentioned position provides condition.

Make brachial plexus block anesthesia and still do not have special-purpose anaesthetic puncture needle clinically existing, multiselect adopts this pin to have following weak point as the brachial plexus block anesthesia puncture needle with common No. 7 or the replacement of 22G entry needle at present:

1. nerve block is incomplete, cause anesthesia failure or poor effect: because each nervous ramification of trunk of brachial plexus is distributed in the different level of nerve sheath, spatium intermusculare, can only inject local anaesthetics by single-point with the normal injection pin, local anaesthetics can not block all brachial plexus nerve branches.Obtain the good anesthesia effect and must carry out multiple spot, the puncture of multi-direction, stage construction and injection.This just must increase puncture time, increase the weight of tissue injury, increase patient's misery, because multiple spot, multi-direction, stage construction puncture injection require the doctor to have quite high operation experience, the quality of anaesthetic effect depends on doctor's operant level and clinical performance situation fully, if have not reach specific operation requirement, will cause anaesthetic effect incomplete, serious also can produce the excessive poisoning of local anaesthetics etc.

2. operation inconvenience: it is very inconvenient to carry out the puncture and injection of medicine operation with the normal injection pin, because the tail end of entry needle directly is contained on the syringe, during operation, hands should be held syringe needle and buttress syringe again, hands is easily shaken when operation, causes site of puncture and paracentesis depth out of control, in addition no scale sign on the shank, paracentesis depth can not be directly judged, position, needle point place can't be measured.This puncture needle can't be observed and differentiates after puncture pumpback liquid, thereby cause the not good or failure of anaesthetic effect, even serious complication of anesthesia takes place, and be strayed in subarachnoid space or epidural space or the blood vessel as local anaesthetics, cause body spinal analgesia or local anaesthetics to poison.

Summary of the invention:

Goal of the invention of the present utility model provides a kind of brachial plexus block anesthesia puncture needle.

Brachial plexus block anesthesia puncture needle described in the utility model, prolonging pipe by shank, handle, PVC forms, handle is fixed on the rearward end of shank, and the end that PVC prolongs pipe is connected with the tail end of shank, and the other end that PVC prolongs pipe is provided with the interface that links to each other with syringe; Be provided with the needle point on one-sided inclined-plane at the front end of shank, on the side of shank leading portion, be provided with the side liquid outlet, on shank, also be provided with scale.

As special case of the present utility model, the side liquid outlet is arranged on the opposite side on needle point front end inclined-plane, in the scope of needle tip 0.5～1.0cm; Described handle is the double-vane handle.

With this utility model as the brachial plexus block anesthesia puncture needle, when clinical anesthesia, the operator is as long as one hand pinches the double-vane handle, according to scale shown on the puncture needle shank, fascia break through affirmations such as sense, the different sense of patient puncture put in place after, to use another hand operated syringe, inject an amount of local anaesthesia medicinal liquid to predetermined anesthesia position, the local anaesthesia medicinal liquid by the side liquid outlet on needle point and the shank from different directions simultaneously, different levels inject brachial plexus nerve trunk and branch, thereby obtain satisfied anaesthetic effect.It can overcome the defective of being brought as the brachial plexus block anesthesia puncture needle with common No. 7 or 22G entry needle, provides a kind of easy to use, economical and practical for clinical, and anaesthetic effect is good, the brachial plexus block anesthesia puncture needle that complication is few.
