Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the sting device structural representation of the embodiment of the invention;
The specific embodiment
For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings, the present invention is described in more detail.
The utility model discloses a kind of sting device that is used for intercostal nerve block, comprise a roll adjustment assembly, first support and second support, above-mentioned first support and second support are arranged at roll adjustment assembly both sides, and the roll adjustment assembly can be adjusted distance between first support and second support.Particularly, first support 1 is the cylindrical hollow pipe, long 38mm, and diameter 5mm, transparent, hollow pipe indicates scale outward; Second support 2 is cylindrical transparent hollow tube, long 38mm, and diameter 5mm, there is the 1.5mm slit in the outside.Sting device also comprises a puncture needle, and above-mentioned puncture needle further comprises needle body 5, needle stand 6 and needle point 7.Puncture needle is arranged in second support 2, and second support 2 can allow puncture needle to pass through, and after puncture needle passed second support 2, the end of needle point 7 distances second support was 2mm.And can under the situation that does not change the puncture needle position, remove second support 2.Particularly, the roll adjustment assembly further comprises roll adjustment screw 3 and adjusting screw nut 4, and above-mentioned roll adjustment assembly is the screw assembly that can adjust first support 1 and second support, 2 distances.
When carrying out intercostal nerves puncture operation, hand-held first support 1 of operator supports the rib surface of bone of extremely plan retardance as location and fulcrum through skin, adjust the roll adjustment assembly (comprising roll adjustment screw 3 and adjusting screw nut 4) between first support 1 and second support 2, make second support, 2 next-door neighbour's rib lower edges, the degree of depth is parallel with the rib surface of bone, puncture needle (particularly, this utility model is exemplified as No. 7 puncture needles of medical field, length 40mm) enters from second support 2, because the length of second support 2 is 38mm, than the short 2mm of the length of puncture needle, therefore, puncture needle is directly entered in the costal groove of rib lower end, after puncture needle puts in place by second support 2, do not have blood and gas through pumpback as confirming, just can carry out the injection operation and carry out intercostal nerve block.Above-mentioned, puncture needle further comprises needle body 5, needle stand 6 and needle point 7.Owing to leave the gap on the tube wall of second support 2, therefore after puncture needle puts in place, remove above-mentioned second support 2, still can freely change the angle of puncture needle, therefore can carry out wider retardance or other operation technique.
Particularly, fulcrum and positioner when first support 1 can be used as operation are clearly intended the intercostal nerves position and the degree of depth that puncture.First support 1 and second support 2 are cylindrical transparent hollow tube, length is 38mm, diameter is 5mm, than the short 2mm of conventional No. 7 needle length of using, when undergoing surgery, puncture needle inserts second support 2, and the tip of puncture needle can correctly be arrived in the costal groove of rib lower edge, particularly, the degree of depth that enters costal groove is 2mm.
In this utility model embodiment, the size of above-mentioned sting device and length are to design according to intercostal nerve block No. 7 puncture needles commonly used.The length of first support 1 and second support 2 is dark in order to prevent that puncture needle from thrusting, as thrusts deeply, has the danger that causes pneumothorax.Certainly, this sting device also can be adjusted the length and the diameter equidimension of first support 1 and second support 2, and then the puncture needle that is suitable for other specification operation that undergos surgery.
Roll adjustment assembly (comprising roll adjustment screw 3 and adjusting screw nut 4) is one can adjust the device of distance between first support 1 and second support 2, operate by the adjusting screw nut 4 that is fixed on first support 1, (Fig. 1 is the sting device structural representation), see this sting device from the left side of structural representation, if turn clockwise adjusting screw nut 4, second support 2 will be shortened near distance between first support, 1, the first support 1 and second support 2; If being rotated counterclockwise adjusting screw nut 4 will increase second support 2 away from distance between first support, 1, the first support 1 and second support 2.
The accuracy that the technical program has effectively avoided puncturing in the method for intercostal nerve block in the prior art costal groove is not enough, paracentesis depth is difficult for grasping, and the shallow medicine that punctured can not block intercostal nerves, does not reach blockage effect, it is dark to puncture, and the danger that causes pneumothorax is arranged.This sting device person of being convenient to operation accurately grasps paracentesis depth, when effectively realizing blockage effect, reduce post-operative complication, alleviate the patient suffering, improved the degree of accuracy of intercostal nerve block puncture, and this technical scheme is convenient, easily grasp, with low cost, safe, be convenient to use, can effectively solve operation technique at the technical field of medical instruments intercostal nerve block at medical field.
In sum, this utility model provides a kind of sting device that is used for intercostal nerve block, comprise a roll adjustment assembly, first support and second support, above-mentioned first support and second support are arranged at roll adjustment assembly both sides, and the roll adjustment assembly can be adjusted distance between first support and second support.The above-mentioned sting device person of being convenient to operation accurately grasps paracentesis depth, when effectively realizing blockage effect, reduce post-operative complication, alleviate the patient suffering, improved the degree of accuracy of intercostal nerve block puncture, and this technical scheme is convenient, easily grasp, with low cost, safe.
More than a kind of sting device that is used for intercostal nerve block provided by the utility model is described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand the solution of the present invention; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
