Abstract
The invention discloses an anesthesia spinal needle with a negative-pressure inner needle core. The anesthesia spinal needle comprises a puncture needle, the negative-pressure inner needle core and a needle lug, wherein the inner needle core is hollow; an elastic film is arranged at the front end of the inner needle core; and a negative-pressure device is arranged at the rear end of the inner needle core. The anesthesia spinal needle has the advantages that the needle core is the negative-pressure needle core and is not required to be unplugged in the whole puncture process, and the inner needle core serves as a negative-pressure tube, so that the anesthesia spinal needle is convenient and efficient; and moreover, ligamentum flavum and the like are not cut off, but are only dissected bluntly, so that injury is reduced, and the lumbago incidence rate of a patient is greatly reduced. By the anesthesia spinal needle, the negative-pressure tube has a good negative-pressure effect regardless of the magnitude of epidural negative pressure of the patient, so that complications of injury of nerve roots or spinal marrow due to continuous needle inserting when negative pressure is deficient are reduced, anesthesia safety is improved, and the patient can be safe in an anesthesia puncture process.
Description
Technical field
The invention belongs to and relate to a kind of anesthesia spinal needle with nook closing member in negative pressure, belong to technical field of medical instruments.
Background technology
The client need epidural anesthesia of the selection nearly 50% of the anesthesia of patient that need to be treated surgically, the instrument that epidural anesthesia is used is anesthesia spinal needle, the quality of anesthesia spinal needle has a great impact anesthetic puncture technology, up to the present about anaesthetic puncture needle, have a lot of inventions to improve, but these invention improvement still have weak point and there is no large-scale promotion application clinically.Tissue and clottage puncture needle because of cutting when patient is expert at anesthetic puncture do not produce negative pressure and cause injured nerve root or spinal cord, thereby the example that causes nerve injury or paraplegia happens occasionally, and after epidural puncture, the incidence rate of lumbago is also very high, in view of this anesthesia spinal needle has been invented in above situation design, to can reduce complication of anesthesia, the injury of minimizing to patient, makes the safer of anesthetic puncture technology change.
At present conventional epidural anaesthetic puncture needle is comprised of anesthesia spinal needle, interior nook closing member, negative tube, disposable use glass syringe etc.During puncture, first pierce through skin, subcutaneous tissue, supraspinal ligament and interspinal ligaments, when puncture needle needle point arrives ligamenta flava, will extract interior nook closing member, connect negative tube and wear out again ligamenta flava, because epidural space has negative pressure, thereby be transmitted to negative tube and occur negative pressure.While piercing through ligamenta flava, to cut ligamenta flava, the tissue that these cut down and blood clot etc. easily block anesthesia spinal needle pin chamber, when total blockage pin chamber, epidural space negative pressure passes less than negative tube, make negative tube not occur negative pressure, while continuing inserting needle, can cause penetration damage nerve root or wear out spinal dura mater Spinal Cord, causing the severe complications such as patient's nerve injury or paraplegia.Anesthesia spinal needle sustains damage it because cutting ligamenta flava when puncture ligamenta flava, causes occurring lumbago after many patient's epidural anesthesias, and some patients were can not be cured for a lot of years.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of anesthesia spinal needle with nook closing member in negative pressure for above the deficiencies in the prior art.
The present invention is achieved by the following technical solutions: the anesthesia spinal needle with nook closing member in negative pressure, comprise puncture needle, the interior nook closing member with negative pressure, pin ear, and interior nook closing member is hollow, and front end is with elastica, and rear end is provided with negative pressure device.
Further, described puncture needle is hollow.
Further, described interior nook closing member front end is with elastica.
Further, in described negative pressure device, be provided with elastica.
Further, described negative pressure device is provided with switch side opening.
Further, described interior nook closing member is that non-toxic, colorless transparent plastic is made.
Further, the outer surface of described puncture needle indicates scale.
The invention has the beneficial effects as follows: the present invention is designed to negative pressure nook closing member nook closing member, in puncture overall process, need not transfer to, interior nook closing member is as negative tube, more convenient and quick, because there being the interior nook closing member of the front end band elastica of hollow, thereby to ligamenta flava etc. without cutting just blunt separation reduce damage, patient's lumbago incidence rate is reduced greatly; Also make when puncture needle is worn out ligamenta flava negative pressure more obvious, reduced the complication that continues inserting needle injured nerve spinal cord because lacking negative pressure, improved the safety of anesthesia, so patient's hard film external anesthetic puncture is safer.
Accompanying drawing explanation
In order to be illustrated more clearly in technical scheme of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparent, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is frame construction drawing of the present invention.
In figure: 1. puncture needle, 2. interior nook closing member, 3. elastica, 4. pin ear, 5. elastica, 6. switch side opening, 7. negative tube.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of patent of the present invention is explained in detail, in conjunction with Fig. 1, with the anesthesia spinal needle of nook closing member in negative pressure, comprises puncture needle 1, interior nook closing member 2, pin ear 4, puncture needle 1 is hollow, and its outer surface indicates scale; Interior nook closing member 2 is made for non-toxic, colorless transparent plastic, and front end is with elastica 3, and rear end is provided with negative pressure device, is provided with that elastica 5, side are provided with switch side opening 6, rear end connects negative tube 7 in negative pressure device.After this puncture needle is through skin, subcutaneous tissue, interspinal ligaments, needle point can be filled with a certain amount of air by switch side opening while arriving ligamenta flava, in interior nook closing member, there is certain pressure, elastica in negative tube is expanded to some extent, closing switch, rear end negative tube saline injection capillary water column, the pressure having because of epidural space negative pressure and interior nook closing member when puncture needle head is broken through ligamenta flava and entered epidural space makes interior nook closing member front end elastica have expanding and making interior nook closing member rear end elastica retraction to epidural to a certain degree, at negative tube, occurs obvious negative pressure.
As described above, be only preferred embodiment of the present invention, is not used for limiting practical range of the present invention, and all equalizations of doing according to the present invention change and modify, and are all the claims in the present invention scope and contain, and give an example no longer one by one here.
