Description
Technical Field
The utility model relates to a medical apparatus, in particular to a nerve block puncture needle.
Background
The nerve block is one of the most important anesthesia and analgesia modes in the anesthesia department, is widely applied to various operations and postoperative analgesia, and has the characteristics of good anesthesia effect, small influence on important systems of human body circulation and the like. With the development of the ultrasonic-guided nerve blocking technology in clinical work, the safety and the accuracy of the nerve blocking technology are further improved, so that the technology is more widely applied to clinical anesthesia and analgesia.
The nerve block puncture needle adopted in China or imported at present adopts the shape of an inclined plane needle point, and an injection hole (a hollow cavity) on a needle body is directly led out on the inclined plane needle point and belongs to a straight-through hole. When the nerve block puncture operation is performed, an anti-blocking needle core is also configured, and the needle point part of the anti-blocking needle core is provided with an inclined needle point which is the same as the needle point of the puncture needle. The anti-blocking needle core has the advantages that the anti-blocking needle core is pulled out after the puncture is finished, then the anti-blocking needle core is connected with the injector through the infusion hose, and anesthetic is injected through the puncture needle. However, for some nerve blocking methods, such as various in-plane nerve block anesthesia techniques, the straight-through manner of the hollow cavity (injection hole) of the bevel type puncture needle has certain disadvantages. Although the planar position of the anesthetic to be injected can be clearly seen under the guidance of ultrasound with the most commonly used plane block of the transverse abdominal muscle in clinical anesthesia and postoperative analgesia, the specific position and distribution of the anterior abdominal wall nerve branches (chest 6-waist 1) of the human body in the plane are not clear. Therefore, it is desirable to achieve sufficient in-plane diffusion of the injected drug to meet the needs of surgical anesthesia and post-operative analgesia. Due to the straight-through mode of the hollow cavity (injection hole) of the inclined plane type puncture needle, the medicine is mainly diffused in one direction after being injected, and the requirement that the common transverse abdominal muscle plane block can fully diffuse the injected medicine in the plane to the periphery cannot be met. Therefore, improvements and improvements in the prior art are necessary.
Disclosure of Invention
In view of the current state of the technology, the utility model provides a nerve block puncture needle, which not only saves a special anti-blocking needle, but also can ensure that the injection anesthetic can be diffused to the surrounding plane after being injected by the puncture needle so as to improve the effects of anesthesia and postoperative analgesia.
The technical solution of the utility model is as follows: a nerve block puncture needle comprises a puncture needle body, wherein a puncture needle body seat is fixed at one end of the puncture needle body, the other end of the puncture needle body is a needle point, and a hollow cavity for injecting medicine is arranged in the puncture needle body; the puncture needle body is provided with a hollow cavity, a needle point is arranged in the puncture needle body, the hollow cavity extends to the needle point and is cut off to form a non-through blind hole needle point, and at least two medicine injection holes which are communicated with the hollow cavity of the puncture needle body in a crossing way are arranged at the blind hole needle point. Therefore, the medicine with the same dosage can be diffused more widely in the injection plane in the same time, and the anesthesia and postoperative analgesia effects are improved.
In the present invention, the blind hole tip is in the shape of a bevel tip or a cone tip.
In the novel medicine injection device, the medicine injection hole is arranged on the blind hole needle point or in the radial direction of the puncture needle body close to the blind hole needle point.
In the utility model, a mark corresponding to the position of the medicine injection hole is arranged on the puncture needle base.
In the utility model, the surface of the puncture needle body is distributed with a golden coating layer for observing the puncture position of the puncture needle by ultrasonic waves according to a certain interval.
The utility model has the beneficial effects that: through the improved nerve block puncture needle, the medicines are injected in a plurality of directions for puncturing the skin and subcutaneous tissues, so that the medicines with the same dosage can be more widely diffused in an injection plane in the same time, and the anesthesia and postoperative analgesia effects are effectively improved. The medicine injection holes are distributed in the lateral direction of the needle point of the blind hole, so that blockage is avoided, the configuration of an anti-blocking needle core is omitted, and the operation procedures are reduced.

Detailed Description
The utility model will be further explained with reference to the embodiments of the drawings.
A nerve block puncture needle shown in fig. 1 to fig. 3, which comprises a puncture needle base 1, wherein a puncture needle body 3 is arranged on the puncture needle base 1, and a hollow cavity 4 and a needle point 6 arranged at the end part are arranged in the puncture needle body 3. In this embodiment, the hollow cavity 4 in the puncture needle body 3 extends to the needle point 6 and is cut off to form a non-straight blind hole needle point, and the blind hole needle point 6 is a needle point with an inclined plane. Two medicine injection holes 5 (only one is marked in the figure) which are crossly communicated with the hollow cavity 4 of the puncture needle body are symmetrically arranged at the needle point 6 of the blind hole. The two medicine injection holes 5 are symmetrically arranged at 180 degrees, so that the medicine injection holes 5 correspond to two sides of the hollow cavity 4 of the puncture needle body 3. Therefore, the medicine with the same dose can be diffused more widely in the injection plane through the symmetrical medicine injection holes 5 in the same time, and the anesthesia and postoperative analgesia effects are improved. In the above, the puncture needle base 1 is provided with the mark 2 corresponding to the position of the medicine injection hole 5. Thus, the position of the drug injection hole 5 can be known, and the diffusion position of the drug is convenient to grasp. In this embodiment, in order to facilitate observation of the puncture depth and position of the puncture needle body 3, gold coating layers 7 for ultrasonically observing the puncture position of the puncture needle are distributed on the surface of the puncture needle body 3 at certain intervals.
In the above, the medicine injection holes 5 are arranged in the radial direction of the puncture needle body 2 near the inclined blind needle point based on the feature that the medicine injection holes 5 are distributed on the blind needle point 6. The site of diffusion of the drug can also be achieved.
Fig. 4 and 5 show different embodiments of the blind needle tip in the shape of a beveled tip as in fig. 1. The needle point is different from the bevel needle point blind hole needle point in the figure 1 in that a cone-point blind hole needle point 16 is adopted, and the cone-point blind hole needle point 16 is symmetrically provided with medicine injection holes 5.
In the above, besides the medicine injection holes 5 symmetrically arranged on the cone-tip-shaped blind hole needlepoint 16, the medicine injection holes 5 may be symmetrically arranged in the radial direction of the puncture needle body 2 near the cone-tip-shaped blind hole needlepoint 16.
Fig. 6 shows a reference diagram of the usage state of fig. 1. One end of a transfusion hose 8 is connected with a puncture needle seat 1 of the puncture needle, and the other end is connected with an injector 9 filled with anesthetic. When carrying out the nerve block puncture, will puncture needle body 3 and pass extraabdominal oblique muscle, intra-abdominal oblique muscle to the flat position of transverse muscle of abdomen respectively and block, later will inject the anesthesia medicine through syringe 9, discharge the back through the medicine injection hole, obtain a more extensive diffusion plane, effectively improve anesthesia and postoperative analgesia effect.
