Abstract

A parallel combined spinal-epidural integrated needle comprises an epidural puncture needle, an epidural anesthetic catheter and a spinal anesthesia puncture needle, and is characterized in that an independent spinal anesthesia needle passage is arranged outside or inside the epidural puncture needle. When puncture with the epidural needle is finished, an epidural outer tube can be inserted first after the spinal anesthesia needle penetrates into the independent passage according to anesthetic requirements. When a surgery is undertaken, intervertebral spaces are conventionally positioned, the parallel integrated needle penetrates through the dura, and after measurement is correct, the spinal anesthesia needle is inserted into independent spinal anesthesia needle passage for administration before the epidural catheter is inserted in case that unilateral spinal anesthesia is selected, and the epidural catheter is inserted before the spinal anesthesia needle is inserted for administration in case that conventional spinal anesthesia is selected. Compared with the prior art, the parallel combined spinal-epidural integrated needle has the advantages that the needle is quicker and more convenient in use, free of multiple positioning and puncturing, wide in application and high in anesthetic comfort level, anesthetic sequence is flexibly selected according to surgical requirements, and the like.

Description

Block form combined spinal-epidural one body acupuncture

Technical field

This utility model relates to a kind of medical medical apparatus and instruments, relates to a kind of medical block form combined spinal-epidural one body acupuncture specifically.

Background technology

At present, the known following operating combined spinal-epidural anesthesia puncture needle of waist and belly that is used for, it comprises anesthesia spinal needle, segmental epidural catheter and lumbar anesthesia puncture needle, anesthesia spinal needle has a tube chamber, its concrete operations divide two kinds of methods, a kind of is that the patient's waist intervertebral space is thrust to the puncture needle tubing in elder generation when performing the operation, then the lumbar anesthesia puncture needle is inserted the tube chamber of puncture needle tubing, the lumbar anesthesia lancet puncture is gone into subarachnoid space inject anaesthetic, after extracting the lumbar anesthesia puncture needle, again segmental epidural catheter is inserted the tube chamber of puncture needle tubing, insert patient's stiffness of the waist film exocoel, if patient's dura mater pipe is inserted difficulty in this case, the effect of one-sided lumbar anesthesia will appear, do not reach our needed anaesthetic effect; And another kind is separately 2 punctures of stiffness of the waist pin, this deficiency that has not had a body acupuncture, can freely select to lumbar anesthesia or peridural order, but 2 punctures can cause suffering to patient again, and the complication of intravertebral anesthesia increases because of the increase of site of puncture and number of times, the danger that medical tangle takes place increases greatly, brings inconvenience to clinical treatment work.

The utility model content

The purpose of this utility model provides a kind of block form combined spinal-epidural one body acupuncture, to overcome the deficiency of known technology.

The technical scheme in the invention for solving the technical problem is:

Block form combined spinal-epidural one body acupuncture, it comprises anesthesia spinal needle, segmental epidural catheter and lumbar anesthesia puncture needle, its special character is that the outside of anesthesia spinal needle or inboard have an independently spinal needle passage, after the epidural needle puncture, after needs can select to insert the dura mater outer tube earlier according to anesthesia, penetrate spinal needle in the autonomous channel, the middle part of anesthesia spinal needle has segmental epidural catheter and inserts tube chamber.The predetermined bits intervertebral space often of performing the operation wears block form one body acupuncture to epidural, measure errorless after, as selecting one-sided lumbar anesthesia, again insert epidural catheter after can inserting the spinal needle administration by independent spinal needle passage earlier according to the operation specific requirement; As select conventional lumbar anesthesia, after then elder generation implants epidural catheter, insert the spinal needle administration again.After having avoided a conventional body acupuncture lumbar anesthesia, the dura mater outer tube is inserted the one-sided lumbar anesthesia of non-needs that difficulty occurs, and operation is carried out smoothly.

That this utility model compared with prior art has is convenient to use, need not repeatedly localised puncture, can select anesthesia order, applied widely, anesthesia satisfaction advantages of higher flexibly according to requirements of operation.

The specific embodiment

As shown in Figure 1, a kind of block form combined spinal-epidural one body acupuncture, it comprises anesthesia spinal needle (1), segmental epidural catheter and lumbar anesthesia puncture needle, have segmental epidural catheter at the middle part of anesthesia spinal needle (1) and insert tube chamber (2), on anesthesia spinal needle (1) inboard or outside tube wall, have a spinal needle passage (3) independently.

Described block form combined spinal-epidural one body acupuncture adopts the conventional epidural needle of 16#, tube chamber thicker when wherein epidural catheter is inserted passage, tube core can be united with spinal needle passage nook closing member and is one, and backshank has the direction deictic function; And special-purpose spinal needle passage has than the tubule chamber, and tube core and epidural nook closing member are united and be one, and this passage and epidural are channel combined to be one arranged side by side.

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.

Claims (1)

1. block form combined spinal-epidural one body acupuncture, it comprises anesthesia spinal needle (1), segmental epidural catheter and lumbar anesthesia puncture needle, the middle part that it is characterized in that anesthesia spinal needle (1) has segmental epidural catheter and inserts tube chamber (2), has a spinal needle passage (3) independently on anesthesia spinal needle (1) inboard or outside tube wall.
