Combined anesthesia device

Abstract

The invention discloses a combined anesthesia device in the technical field of medical instruments, which comprises a hard anesthetic needle base, a hard anesthetic needle tube connected to the hard anesthetic needle base, and a hard anesthetic needle core inserted into the hard anesthetic needle tube, wherein the hard anesthetic needle core is arranged on a needle core base; the needle core base is arranged on the hard anesthetic needle base in a matching mode; the end part of the hard anesthetic needle core is matched with the end part of the hard anesthetic needle tube to form a cutting edge; the outside of the hard anesthetic needle tube is welded with a lumbar anesthetic needle tube of which the axis is parallel to that of the hard anesthetic needle tube; the lumbar anesthetic needle tube is shorter than the hard anesthetic needle tube; the end part of the lumbar anesthetic needle tube is a beveling cutting edge obliquely transiting towards the hard anesthetic needle tube; the lumbar anesthetic needle tube is internally provided with a hollow lumbar anesthetic needle core in a matching mode; and the root of the lumbar anesthetic needle core is fixed on a lumbar anesthetic needle base. When the device is used, the hard anesthetic needle core and the hard anesthetic needle tube are punctured into an endorhachis epidural space, and meanwhile, and the lumbar anesthetic needle core is punctured into a subarachnoid space to carry out combined anesthesia of epidural anesthesia and lumbar anesthesia at the same time so as to shorten the anesthesia waiting time, and realize sustainable anesthesia in surgery at the same time.

Description

Technical field [0001] The invention relates to a medical device, in particular to a medical device for anesthesia. Background technique [0002] Spinal epidural anesthesia (abbreviated as epidural anesthesia): is to inject anesthetics into the epidural space to block part of the spinal nerves and produce anesthesia. Subarachnoid anesthesia (spinal anesthesia for short): Inject anesthetics into the subarachnoid cerebrospinal fluid of the waist to block part of the spinal nerves. The scope of anesthesia is often limited to the lower body, so it is also called half-body anesthesia. The anesthesia range of epidural anesthesia is smaller than spinal anesthesia, and the waiting time for anesthesia is longer. [0003] In the prior art, there is a medical device for epidural anesthesia—a hard anaesthetic needle. Its structure mainly includes a hard anaesthetic needle seat, a hard anaesthetic needle tube is connected to the hard anaesthetic needle seat, and a hard anaesthetic needle is i...

Problems solved by technology

[0003] In the prior art, there is a kind of medical equipment for epidural anesthesia—the hard anesthesia needle. Needle core, the hard hemp needle core is installed on the needle core seat, the needle core seat is matched and installed on the hard hemp needle seat, the end of the hard hemp needle core and the end of the hard hemp needle tube cooperate to form a cutting edge, which can puncture Enter the spine, let the hard anesthesia needle tube enter the epidural space, at this time, pull out the hard anesthesia needle core, inject local anesthetic drugs through the catheter into the epidural space through the hard anesthesia needle tube, and anesthetize the human body; Anesthesia is performed through the epidural space, and the waiting time for anesthesia is longer. If spinal anesthesia is required, pull out the hard anesthesia needle core, reinsert a hollow spinal anesthesia needle, and puncture the needle tip of the spinal anesthesia needle into the spider web Subarachnoid space, through the spinal anesthesia needle to give medicine to the subarachnoid space, realize spinal anesthesia, the above-mentioned anesthesia process is realized through a needle tube, it cannot administer anesthesia to the epidural space and subarachnoid space at the same time, therefore, its The waiting time for anesthesia is long and the anesthesia effect is relatively poor
