Abstract

The utility model relates to a side needle for a disposable combined spinal-epidural anesthesia puncture needle. The side needle comprises a needle handle, a needle tube, a needle point and a needle core, wherein, the needle tube is divided into two cavities, one of which is a lumbar anesthesia cavity for a lumbar anesthesia needle passing by and the other one of which is a catheter cavity in which an epidural anesthetic tube is put, and scales are arranged on the surface of the needle tube; the needle handle is a handheld part when the doctor performs the puncture, and a lumbar anesthesia orifice and a catheter cavity orifice which enters the lumbar anesthesia cavity are arranged at the upper end of the needle handle; the needle point is a needle point of an ordinary epidural puncture needle with a radian so as to reduce the damage to human tissues; the needle core is divided into a lumbar anesthesia core passing through the lumbar anesthesia cavity and a catheter core passing through the catheter cavity so as to prevent the human tissues from entering into the puncture needle cavity when the puncture is performed. The side needle has the advantages that the needle tube is provided with two cavities, the puncture needle performs the lumbar anesthesia and can be put in the epidural anesthesia catheter simultaneously, therefore, the anaesthetic time can be saved, the anaesthetic complicating disease in the canalis vertebralis is reduced, the anaesthetic practicability in the canalis vertebralis and the security of the patient are enhanced.

Description

The disposable use waist-other pin of hard combined anesthesia puncture needle

Technical field

The novel a kind of disposable use waist-other pin of hard combined anesthesia puncture needle that uses in a kind of waist-hard connection anesthesia that relates to of this use.

Background technology

During clinical waist-hard combined anesthesia, after needing puncture anesthesia spinal needle successfully earlier, the reuse spinal needle punctures through epidural puncture needle lumen row subarachnoid space, after the cerebrospinal fluid outflow, injects required local anaesthetics in subarachnoid space.Withdraw from spinal needle then, insert segmental epidural catheter through anesthesia spinal needle again, again epidural needle is withdrawed from.The deficiency of this mode is: if it is inaccurate or insert segmental epidural catheter failure time and again to insert the segmental epidural catheter position, all can cause the complication of intravertebral anesthesia, even the doctor can only abandon the mode of intravertebral anesthesia.So need a kind of puncture needle that can insert row lumbar anesthesia behind the segmental epidural catheter earlier of development, can make anesthesia procedure more reasonable like this, guarantee the success of associating puncture, reduce the complication of intravertebral anesthesia.

The utility model content

This utility model can be realized the aforesaid operations requirement, saves anesthesia duration, reduces the complication of intravertebral anesthesia.

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

A kind of disposable use waist-other pin of hard combined anesthesia puncture needle, it comprises: needle handle, needle tubing, needle point, nook closing member.Wherein, needle tubing is divided into two chambeies, and one is the lumbar anesthesia chamber passed through of spinal needle and insert the catheter lumen of segmental epidural catheter, and there is scale on the needle tubing surface; Needle handle is doctor hand-held position when puncturing, and there is the spinal needle mouth of pipe and the catheter lumen mouth of pipe that enters the lumbar anesthesia chamber its upper end; Needle point is the needle point that has the common anesthesia spinal needle of radian, to reduce the damage to tissue; Nook closing member is divided into by the lumbar anesthesia core in lumbar anesthesia chamber and the catheter core by catheter lumen, and tissue enters the puncture needle intracavity when preventing to puncture.

Described needle tubing is divided into two chambeies, one is the lumbar anesthesia chamber passed through of spinal needle and insert the catheter lumen of segmental epidural catheter, the lumbar anesthesia of can going simultaneously punctures and inserts segmental epidural catheter, has saved the time of waist-hard combined anesthesia puncture, has reduced the generation of its complication.

Described nook closing member is divided into by the lumbar anesthesia core in lumbar anesthesia chamber and the catheter core by catheter lumen, and tissue enters the puncture needle intracavity in the time of can preventing to puncture, and reduces the damage to tissue, reduces the generation of complication.

The other pin of described disposable use waist-hard combined anesthesia puncture needle, simple to operate, save the puncture time, reduce the generation of complication and increased the practicality of waist-hard combined anesthesia.

The specific embodiment

As Figure 1-3, a kind of disposable use waist of the present utility model-other pin of hard combined anesthesia puncture needle, it comprises: needle handle 1, needle tubing 2, needle point 3, nook closing member 4.Wherein, needle tubing 1 is divided into two chambeies, and one is spinal needle lumbar anesthesia chamber 2-1 that passes through and the catheter lumen 2-2 that inserts segmental epidural catheter, and there is scale 2-3 on needle tubing 2 surfaces; Needle handle 1 is doctor hand-held position when puncturing, and there is spinal needle mouth of pipe 1-1 and the catheter lumen mouth of pipe 1-2 that enters the lumbar anesthesia chamber its upper end; Needle point 3 is the needle points that have the common anesthesia spinal needle of radian, to reduce the damage to tissue; Nook closing member 4 shapes are consistent with trend and needle tubing, are divided into lumbar anesthesia core 4-1 by the lumbar anesthesia chamber and the catheter core 4-2 by catheter lumen, and tissue enters the puncture needle intracavity when preventing to puncture.

As shown in Figure 3, described needle tubing is divided into two chambeies, one is spinal needle lumbar anesthesia chamber 2-1 that passes through and the catheter lumen 2-2 that inserts segmental epidural catheter, the lumbar anesthesia of can going simultaneously punctures and inserts segmental epidural catheter, save the time of waist-hard combined anesthesia puncture, reduced the generation of its complication.

As shown in Figure 2, described needle handle 1 is doctor hand-held position when puncturing, there is spinal needle mouth of pipe 1-1 and the catheter lumen mouth of pipe 1-2 that enters the lumbar anesthesia chamber its upper end, the promising respectively catheter core 4-2 that passes through the lumbar anesthesia core 4-1 in lumbar anesthesia chamber and pass through catheter lumen on it, tissue enters the puncture needle intracavity in the time of can preventing to puncture, minimizing reduces the generation of complication to the damage of tissue.

This utility model number described disposable use waist-other pin of hard combined anesthesia puncture needle, by anesthesia doctor operation, its operation is identical with general anesthesia puncture needle mode in use, and the lumbar anesthesia of can going simultaneously puncture is inserted with segmental epidural catheter.

The disposable use waist described in the utility model-other pin of hard combined anesthesia puncture needle, simple to operate, this pin is compared with widely used clinically combined puncturing needle now, maximum difference is: the anesthesia doctor epidural puncture of can going ahead of the rest on clinical manipulation, put and go the subarachnoid space puncture after managing successfully again, improve present combined anesthesia operation and gone up the irrationality of beating earlier the rearmounted epidural catheter of lumbar anesthesia, greatly reduce the risk of putting pipe difficulty, reduce the generation of complication and increased the practicality of waist-hard combined anesthesia.

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.
