The utility model provides a kind of puncture sampling catheter, belong to puncture sampling catheter technical field, the puncture sampling catheter includes: main pipe body, inner needle assembly, rotating handle, sealing cover and fixed seat;The main pipe body is hollow cylindrical structure, the distal end of main pipe body is equipped with bevel opening, and the proximal end of main pipe body is equipped with connecting port;The inner needle assembly includes needle and needle handle, needle and needle handle are fixedly connected, and the needle can be slidably arranged in the inner cavity of main pipe body;The proximal end connecting port of main pipe body is fixedly connected with rotating handle;Sealing cover is installed at the proximal end connecting port of main pipe body by thread connection, and the center of sealing cover is provided with through-hole, needle handle passes through the through-hole of sealing cover center and is connected with fixed seat;The fixed seat is arranged outside sealing cover, and the utility model solves the technical problem that the puncture sampling catheter in prior art exists sampling precision is not high, and operation is not flexible.

The invention relates to the technical field of gynecological medical instruments, in particular to a vaginal secretion sampling device which comprises an intubation tube, a sampling assembly, a plurality of expansion assemblies, a plurality of push plates, a limiting frame and an adjusting assembly. One end of the intubation tube is open, and the sampling assembly sleeves the outer surface of the intubation tube. The plurality of expansion assemblies are arranged in the insertion pipe, and the plurality of push plates are arranged between the insertion pipe and the sampling assembly. The limiting frame is fixedly arranged at the open end of the insertion pipe and comprises a guide cylinder. The adjusting assembly comprises a position adjusting rod, the position adjusting rod is arranged in the guide cylinder and can slide along the inner wall of the guide cylinder, an ejector rod is fixedly arranged at the end, close to the insertion pipe, of the position adjusting rod, and the central axis of the guide cylinder, the central axis of the position adjusting rod and the central axis of the ejector rod are collinear with the central axis of the insertion pipe. When the device is used, the guide cylinder can limit the position adjusting rod to move along the central axis of the cannula all the time, the ejector rod cannot incline, and the sampling assembly can be uniformly stretched, so that the normal sampling process can be ensured, and the comfort of a female patient is improved.
