Description

Clinical sampling device that uses of pathological medicine

Technical Field

The utility model relates to the technical field of medical equipment, in particular to clinical sampling device that uses of pathological medicine.

Background

Pathological examination is a pathomorphological method for examining pathological changes in organs, tissues or cells of the body. In order to study the disease process of organs, tissues or cells, some kind of pathological morphological examination method can be used to examine the pathological changes of them, study the cause, pathogenesis and the process of pathological changes, and finally make pathological diagnosis. The pathological morphological examination method is that the pathological change of the general specimen is observed, then the pathological tissue with certain size is cut out, the pathological section is made by the pathological histological method, and the pathological change is further examined by a microscope.

The sampling of pathological tissue mostly adopts the mode of puncture to take a sample, wherein puncture sample adopts and to have a sampling needle that has the barb to take a sample in pjncture needle endotheca, but among the prior art, the wearing out or the indentation of sampling needle relative pjncture needle are difficult to control, can only rely on the direct hand propulsion or the ejecting of doctor, and it is not smooth during the operation to be difficult to control the operation precision.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a clinical sampling device that uses of pathological medicine impels or releases the sample through rotatory mode with the sampling needle, and convenient operation is handy, easily control accuracy.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a clinical sampling device that uses of pathological medicine, includes the cylinder, the bottom intercommunication of cylinder has the pjncture needle, sliding connection has the piston in the cylinder, upwards be provided with spacing draw runner from the bottom in the cylinder, the outer wall of piston seted up with spacing draw runner cooperation sliding connection's spacing spout, in the cylinder in the upper end of spacing draw runner is provided with the connecting plug, runs through connecting plug set up threaded hole, threaded hole female connection has the screw thread push rod, the lower extreme of screw thread push rod with the piston rotates to be connected, the lower extreme of piston is connected with the sample needle, the sample needle set up in just sliding connection with it in the pjncture needle, the sample needle is kept away from the sample groove has inwards been seted up to the side of piston one end, the downside in sample groove is provided with the ascending barb.

Through adopting above-mentioned technical scheme, during the puncture sample, at first rotate the screw thread push rod, in retreating the pjncture needle with the sampling needle, penetrate patient's pathological change tissue department through the pjncture needle afterwards, rotate the screw thread push rod, release the pjncture needle with the sampling needle, the in-process of rotating the screw thread push rod, because the cooperation of spacing draw runner and spacing spout makes the piston can not rotate, can only advance or retreat, prevent that the sampling needle from rotating and bring the unnecessary damage for the patient, after the sampling needle is worn out completely in the sample groove, it makes the sample needle retreat to rotate the screw thread push rod, drive the barb and catch on the sample tissue, and bring it into the pjncture needle along with the sample groove, extract the pjncture needle, just can obtain the.

The utility model discloses a further set up to: the top of the piston is downwards provided with a rotating hole with an inverted T-shaped section, and the lower end of the threaded push rod is provided with a rotating connector which is rotatably connected with the rotating hole and has an inverted T-shaped section.

The utility model discloses a further set up to: the tip ends of the puncture needle and the sampling needle are provided with oblique planes which are coincident with each other.

The utility model discloses a further set up to: and a push handle is arranged at the upper end of the threaded push rod.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a screw thread push rod releases the sampling needle or moves back into the pjncture needle, and the doctor operates more handy to be convenient for control release moves back into the degree of depth, makes the sampling needle can not rotate at flexible in-process through the cooperation of spacing draw runner and spacing spout simultaneously, prevents effectively that the sampling needle from rotating and bring the unnecessary damage for the patient.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The embodiment is a clinical sampling device for pathological medicine, and referring to fig. 1-3, the clinical sampling device comprises a needle cylinder 1, the bottom of the needle cylinder 1 is communicated with a puncture needle 2, a piston 3 is connected in the needle cylinder 1 in a sliding manner, four limiting slide bars 11 are arranged in the needle cylinder 1 from the bottom upwards, and four limiting slide grooves 31 which are matched and connected with the limiting slide bars 11 in a sliding manner are arranged on the outer wall of the piston 3.
