Abstract
The utility model belongs to an anaesthesia puncture needle for injecting the anaesthesia. The exiting anaesthesia puncture needle is provided with an extradural puncture needle, and a waist puncture needle, while the extradural puncture needle and the waist puncture needle are used separately. The former exits the muscle relaxation difference, and is not favorable for the lower abdomen and the pelvic operations, while the latter can not be replenished when the operation is not fished, and thus, the latter can only be carried out with the general anaesthesia. In order to overcome the disadvantages, the utility model is provided with a new needle which is combined by the extradural puncture needle and the waist puncture needle. Namely the spoon portion of the extradural puncture needle is provided with a through hole, and a built-in waist puncture needle is arranged in the core of the extradural puncture needle. The utility model has multiple functions.
Description
This utility model belongs to the puncture needle that the injection anaesthetic is used, and particularly carries out the puncture needle of local anaesthesia to the injection through vertebral canal anesthetics.
As everyone knows, when needs of patients carries out operation below the hypogastric region, lumbar anesthesia or the epidural anesthesias of adopting more, lumbar anesthesia can obtain good muscular flaccidity, be beneficial to hypogastric region and operation on pelvis, but anesthesia duration is limited, can not satisfy the operation demand, must change general anesthesia into as performing the operation to finish, and general anesthesia can bring some complication to the patient, as inserting the villous themeda damage, excessive phlegm, pulmonary infection etc., and epidural anesthesia can inject local anaesthetics at any time continuously, prolong anesthesia duration, but is its muscular flaccidity degree poor than lumbar anesthesia, is unfavorable for operation on pelvis operation, as changes both are combined? U.S.'s imagination is got up the advantages of lumbar anesthesia and epidural anesthesia recently, one-time puncture is finished two kinds of anesthesia, design " two villous themeda formula epidural puncture needle ", the effective lumbar puncture needle of a cover of promptly burn-oning abreast on the epidural puncture needle injects anaesthetic through sleeve pipe and carries out lumbar anesthesia, just can finish two kinds of anesthesia simultaneously, but the patient will be through the puncture of wide two pins arranged side by side of about 3-4mm, and the puncture damage is too big.
The purpose of this utility model is to overcoming the defective on the anaesthetic effect, and " double hose epidural puncture needle " designs a kind of novel anesthesia puncture needle that is combined by epidural puncture needle and internally-arranged type lumbar puncture needle to the too big shortcoming of patient's damage.
This utility model is mainly realized by following structure: it is mainly by the epidural puncture needle, the internally-arranged type lumbar puncture needle is formed, said epidural puncture needle has a small through hole at the needle tip spoon back side of its spoonful shape, said internally-arranged type lumbar puncture needle can be through in the nook closing member of epidural puncture needle just, and the lumbar puncture needle needle point passes the small through hole at the epidural puncture needle spoon shape needle tip spoon back side just.
Use the puncture needle of this utility model design, both overcome the anesthesia shortcoming of traditional single use lumbar puncture needle or epidural puncture needle, overcome the two pins shortcoming of using arranged side by side of the U.S. again, satisfied the needs of hospital surgical anesthesia, alleviated patient's misery to greatest extent.
Describe in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the epidural puncture needle, Fig. 2 is a partial enlarged drawing, Fig. 3 is the internally-arranged type lumbar puncture needle, Fig. 4 is epidural puncture needle and internally-arranged type lumbar puncture needle sketch map, Fig. 5 is a view of inserting epidural catheter in the epidural puncture needle, (1) small through hole in the accompanying drawings, (2) epidural catheter, (3) needle point.
Epidural puncture needle as shown in Figure 1, a small through hole is promptly opened along the pin rectilinear direction in the spoon shape needle point position and the back side therein, the Kongzui minor diameter is got 0.4-0.8mm, lumbar puncture needle is as shown in Figure 3 made than minor diameter at its needle point position or needle point section, and this diameter is advisable to guarantee lumbar puncture needle intensity, generally gets 0.4-0.8mm, and get its negative common difference value, after the length of lumbar puncture needle was passed the epidural puncture needle with pin, its needle point position exceeded the needle point top 1cm of epidural puncture needle, as shown in Figure 4.
Comprise the epidural puncture needle with this novel anesthesia puncture needle, the internally-arranged type lumbar puncture needle, when making lumbar anesthesia for the patient with the epidural puncture needle to epidural space, the internally-arranged type lumbar puncture needle is by the epidural puncture needle, pass spinal dura mater and enter cavum subarachnoidale, injecting anaesthetic anaesthetizes, the far-end 1.5cm-2cm place of internally-arranged type lumbar puncture needle has the diameter of a shape from step-like to needle point to pass the aperture at the epidural puncture needle spoon shape needle tip spoon back side just, hole diameter is 0.4-0.8mm, internally-arranged type lumbar puncture needle total length 11cm, also can directly carry out epidural anesthesia with this novel anesthesia puncture needle, utilize the epidural puncture needle to insert epidural catheter and carry out successive anaesthetic injection.What this utility model was the most outstanding a bit promptly is, can do two kinds of anesthesia by a puncture, if reckoned with that before doing lumbar anesthesia the patient is in operation process, the time limit deficiency may appear anaesthetizing, operation is affected, be that available this pin is worn the epidural puncture needle to epidural space earlier, pass spinal dura mater to cavum subarachnoidale with the internally-arranged type lumbar puncture needle, after the injection, the internally-arranged type lumbar puncture needle is extracted, insert epidural catheter to epidural space, the epidural puncture needle is taken out, by epidural catheter, just can inject anesthetics at any time according to situation in the corrective surgery, play anesthetic action, can temporarily not take out epidural catheter after patient's operation, also can inject analgesic by this pipe, thereby play analgesic activity, epidural catheter by the pin hole of anesthesia spinal needle, can not be come in and gone out from the aperture at the spoon back side smoothly.
This utility model is simple in structure, and is easy to use, solved patient's penetration damage and suffered problems such as misery greatly, overcome the defective on the anaesthetic effect, is a kind of instrument practical in the medical apparatus and instruments.
