Abstract
The utility model belongs to the technology of a puncture needle. The puncturing needle with a movable anesthetic plane surface comprises an epidural puncture needle, a soft needle sleeve sheathed at the outer side of the puncture needle, and a puncture needle core which is inserted inside the puncture needle. The puncture needle can also achieve the satisfactory anesthetic plane surface and the satisfactory effect by conveniently adjusting the length of a catheter of epidural anesthesia liquid in an epidural cavity in the process of operations. The utility model is especially suitable for patients who are difficult to be accurate diagnosis before operations, patients who need to be operated in two different plane surface operations, and patients of large anesthesia range of operations. The damage which is caused by multipoint puncture and the patients' pain can be avoided, and the operation time and the operation program can be decreased.
Description
This utility model belongs to the technical field of puncture needle.
The puncture needle that is used for epidural anesthesia now in the surgical operation, include only puncture needle and nook closing member, in the process of implementing anesthesia, the anesthesia liquid input pipe that it is inserted can only be reserved on certain level of anesthesia, the anesthesia liquid input pipe can only outwards be taken out in the process of anesthesia, can not insert inwards, the mobile of level of anesthesia is unidirectional, and level of anesthesia can not arbitrarily move with the needs of operation.
The purpose of this utility model provides a kind of level of anesthesia can be with the needs hard film external anesthetic puncture pin doing to move of operation.
The removable puncture needle of this level of anesthesia comprises anesthesia spinal needle, is enclosed within the soft needle guard of puncture needle outside, is inserted in the puncture needle nook closing member in the puncture needle.
Because soft needle guard is arranged, after inserting the anesthesia liquid conduit, even also can be in operation process more conveniently by adjusting the length of epidural anesthesia fluid catheter at epidural space, reach satisfied level of anesthesia and effect, especially be useful in the patient who is difficult to make a definite diagnosis before the art, the patient and the bigger patient of surgery anesthesia scope that need successively do two kinds of Different Plane operations, avoided multiple spot to puncture, reduced operating time and program to the damage of patient's increase and the misery that causes.
Accompanying drawing shows embodiment of the present utility model, wherein:
Figure 1 shows that the cutaway view of the removable puncture needle of level of anesthesia;
Figure 2 shows that the left view of the removable puncture needle of level of anesthesia;
Figure 3 shows that the right view of the removable puncture needle of level of anesthesia;
The removable puncture needle of level of anesthesia as shown in the figure comprises anesthesia spinal needle 1, is enclosed within the soft needle guard 2 of puncture needle 1 outside, and soft needle guard 2 is the soft needle guard of elasticity.Be inserted in the puncture needle nook closing member 3 in the puncture needle 1, on soft needle guard 2 back seats, be connected with and be inserted on the soft needle guard back seat the fixedly cylindrical cap 4 of catheter, and the centre of medicated cap 4 have the hole by tightrope.
In use, puncture needle and soft needle guard punctured together enter in patient's body, extract nook closing member, insert the anesthesia liquid conduit, extract puncture needle again, soft needle guard and anesthesia liquid conduit put together stay in patient's body, needs according to anesthesia insert certain degree of depth with the anesthesia liquid conduit, in the process of operation, can adjust the insertion depth of anesthesia liquid conduit according to the needs of operation at any time, and the anesthesia liquid conduit passes the hole of medicated cap, with the rear end of cap stopper,, and stop up soft needle guard rear end in order to fixing anesthesia liquid conduit at soft needle guard.
