Drawings
The invention is further described with reference to the accompanying drawings in which:
FIG. 1 is a schematic front view of the present invention (using a pull cord);
FIG. 2 is a schematic front view of the present invention in use (using a pull cord);
FIG. 3 is a schematic right side view of the hollow body of FIG. 1;
FIG. 4 is an enlarged view of the structure at A in FIG. 1
FIG. 5 is a schematic cross-sectional view taken along the line B-B in FIG. 1;
fig. 6 is a schematic cross-sectional view (using a baffle) taken along the direction C-C in fig. 3.
In the figure, a puncture tube 1, a connector 101, anti-skid lines 2, a quadrangular frustum tube 3, liquid sucking holes 4, a hinge shaft 5, a hollow body 6, an inclined surface 7, an opening 8, a pull rope 9, a baffle 10 and an included angle alpha are arranged.
Detailed Description
The drawings illustrate specific embodiments of the invention. As shown in fig. 1 to 6, the cyst fluid puncture aspirator for patients (all the following materials are medical materials) comprises a puncture tube 1, one end of the puncture tube is provided with a connector 101 for connecting a negative pressure source, and then a section of anti-skid veins 2 is arranged, the part can be used as a handle during operation, the anti-skid veins 2 are longitudinal veins, the other end of the puncture tube is provided with a plurality of fluid suction holes, then the diameter of the puncture tube is reduced to a quadrangular frustum tube 3, the end surface of the quadrangular frustum tube 3 is provided with an inclined surface 7, and the inclined angle of the inclined surface 7, namely the included angle alpha between the inclined surface 7 and the cross section of the puncture tube 1 is 10-20 degrees, preferably 15 degrees; the puncture suction head is installed in the matching way of the quadrangular frustum tube 3, the puncture suction head is made of plastic materials, and the specific structure of the puncture suction head is as follows:
the hollow body 6 is a quadrangular pyramid-shaped hollow body 6 consisting of four side plates, the bottom surface of the hollow body 6 is also an inclined surface, the high end of the bottom surface is hinged at the high end of the inclined surface 7 through a hinge shaft 5, a part of the lower end of the hollow body 6 is inserted into the quadrangular frustum tube 3 and forms a little bit of clamping (the friction force is larger and the hollow body cannot automatically rotate because of a slightly tight combination between the quadrangular frustum tube and the hollow body), most of the hollow body 6 stands out of the quadrangular frustum tube 3 when no external force or insufficient external force exists, and the hollow body 6 is integrally rotated and then hidden in the quadrangular frustum tube 3 when the external force is enough; the hollow body 6 has four sides, one side of which, facing away from the pin, is open, i.e. has an opening 8.
In order to control the rotation of the hollow body 6, there are two ways, one of which is to connect a pull cord 9 to the inside of the hollow body 6, the pull cord 9 extending from one of the liquid suction holes 4.
Secondly, a baffle plate 10 is arranged between the lower ends of two opposite side plates of the hollow body 6, and the baffle plate 10 narrows the communication channel between the hollow body 6 and the quadrangular frustum pyramid pipe 3.
The using process is as follows:
the puncture suction head is in an initial state, the puncture suction head stands upright at the upper end of a quadrangular frustum tube 3 under the restraint of the quadrangular frustum tube 3, the connector 101 end of the puncture tube 1 is connected to a negative pressure source, the part with anti-skidding threads 2 is held by a hand, namely a handle, the tip of the puncture suction head, namely the tip of the hollow body 6 is punctured and inserted into a cyst, after puncture, liquid can be pumped, under the resistance action of fluid formed by liquid in the cyst, the hollow body 6 overturns and enters and is hidden in the quadrangular frustum tube 3, the cyst liquid is sucked away along with the gap between the hollow body 6 and the quadrangular frustum tube 3 and the liquid suction hole 4, one position is sucked up, the other position is searched again, in the searching process, the quadrangular frustum tube 3 cannot puncture blood vessels and nerves, secondary injury cannot be caused to a patient, and the puncture suction head is safe and efficient.
If the pull rope 9 is adopted, after the hollow body 6 pierces a cyst, the pull rope 9 is pulled to rotate the hollow body 6 so as to hide the hollow body 6 in the quadrangular frustum pyramid tube 3.
As shown in fig. 6, if the baffle 10 is adopted, after the hollow body 6 is pierced into the capsule, the capsule liquid forms water flow under the action of the negative pressure source and enters the hollow body 6 from the opening to enter the piercing tube 1, so that the capsule liquid can be prevented from overflowing from the piercing opening, in addition, after the water flow is gradually increased, the water flow is blocked by the baffle 10, or the baffle 10 is overturned under the impact of the water flow, and then the hollow body 6 is hidden in the quadrangular frustum tube 3.
Other technical features than those described in the specification are known to those skilled in the art.
