Abstract
The utility model relates to a puncture needle with scales, and the needle body is connected to a needle bed. The puncture needle is characterized in that length scales are longitudinally arranged on the needle body. The puncture needle belongs to clinical medical appliances, and has the advantages of convenient clinical use and convenient accurate operation.
Description
Technical field
This utility model relates to a kind of graduated puncture needle of being with, and belongs to clinical medical appliance.
Background technology
The puncture technique clinical practice is very extensive, and the purpose of puncture is mainly used in diagnosis and treats two broad aspect.The puncture needle of present clinical widespread usage does not all indicate the length scale, makes clinical position have many inconvenience:
(1) now the clinical criteria of widespread usage is that puncture needle cutting edge of a knife or a sword opposing sense disappears when arriving serous cavity, and the sense of breakthrough is arranged, and this breakthrough sense is not obvious in clinical manipulation sometimes, allow the operator have no way of judging to be to or?
(2) dropsy of serous cavity repeatedly, repeatedly biopsy is got in puncture, and the operator will sound out each time, seeks and breaks through sense, does not have accurate yardstick, has brought risk and difficulty to the operator.
(3) punctured and puncture visceral pleura deeply and can cause pneumothorax and pulmonary edema, and punctured the visceral layer pericardium and can cause heart and injury, caused serious adverse consequences.
(4) patient is fat or thin differs, and paracentesis depth also varies with each individual, and brings difficulty to the operator, and uncertainty increases.
The utility model content
The purpose of this utility model is to provide a kind of graduated puncture needle of being with, and is clinical easy to use, is convenient to accurate operation.
Described in the utility modelly be with graduated puncture needle, needle body is connected on the needle stand, it is characterized in that establishing the length scale at needle body on vertically.
Also can mark the length scale on the syringe needle that local anaesthesia is used, bring convenience to the operator.
This utility model compared with prior art has following beneficial effect:
(1) when the up local anesthesia of point of puncture, syringe needle is met to break through and is felt when entering serous cavity, remembers the scale of inserting needle, during reuse lancet puncture serous cavity, remembers scale, and the operator is safety operation easily.
(2) the puncture serous cavity is broken through when feeling not obvious, and it is particularly important that scale just seems, the operator can just can judge whether to arrive serous cavity according to the scale that enters.
(3) avoid dark puncture to cause serious adverse consequences such as pneumothorax, pulmonary edema or heart and injury, avoided the generation of medical tangle.
(4) dropsy of serous cavity repeatedly, pneumatosis, repeatedly biopsy is got in puncture, and the operator can just can operate like clockwork according to scale.
(5) repeatedly biopsy is got in puncture, even puncture is unsuccessful for the first time, the operator also can judge be deeply or shallow according to the scale of inserting needle, for next time successfully puncture invaluable experience is provided.
(6) sense of breakthrough is arranged, add scale accurately, for the serous cavity that successfully punctures provides dual fail-safe.
(7) this utility model puncture needle can be widely used in various puncture techniques, and as various serous cavities puncture (pleural space puncture, peritoneal cavity puncture, pericardial cavity puncture), waist is worn, ilium is worn, liver biopsy, kidney biopsy or the like.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, needle body 2, length scale 3, needle stand.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, described in the utility modelly be with graduated puncture needle, needle body 1 is connected on the needle stand 3, and needle body 1 vertically is provided with length scale 2.
Operate according to the length scale, convenient accurate again.
Claims (1)
1, a kind ofly be with graduated puncture needle, needle body is connected on the needle stand, it is characterized in that needle body vertically is provided with the length scale.
