By figure 1 to 4 and give, including axial and opening barrel 1 down from top to bottom, the coaxial sampling needle 2 rather than the inside intercommunication that is equipped with of 1 lower extreme of barrel, axial sampling tube 3 around 2 upsides of sampling needle are equipped with, 3 rear ends of sampling tube run through barrel 1 and coaxial threaded connection have a receiving flask 4, opening sampling hole 5 backward has been seted up to 2 downside of sampling needle, coaxial sliding connection has opening sampling box 6 backward in the sampling needle 2, sampling box 6 can communicate with sampling hole 5, the lower extreme is equipped with curved cutter 7 in the sampling box 6, coaxial zonulae occludens has the stand pipe 8 that axial cross-section is T shape in the barrel 1, 8 lower extremes of stand pipe stretch into in the sampling needle 2 and with sampling box 6 fixed connection.

In the sample box 6 is pushed into the collecting bottle 4 for the convenience, sample box 6 in coaxial sliding connection have ejector pad 9, the terminal surface is the high inclined plane in low back before the ejector pad 9 down, coaxial zonulae occludens has push rod 10 in the stand pipe 8, push rod 10 lower extreme runs through sample box 6 and with ejector pad 9 fixed connection, push rod 10 upper end run through barrel 1 and with barrel 1 sliding connection.

In order to make sampling box 6 can with the stable intercommunication of thief hole 5, barrel 1 front side open be equipped with rather than inside intercommunication and the slide 11 of upper and lower direction, barrel 1 front side open be equipped with the spacing groove 12 of slide 11 downside intercommunication, 8 upper end front sides of stand pipe are equipped with the slider 13 that is located slide 11, slider 13 can be followed slide 11 and removed and can insert the spacing inslot 12.

In order to facilitate pushing the sliding block 13, an arc-shaped auxiliary plate 14 positioned outside the cylinder 1 is arranged at the front end of the pushing block 13, and a plurality of anti-slip strips 15 distributed along the length direction of the auxiliary plate 14 are arranged outside the auxiliary plate 14.

In order to make the guide tube 8 reset automatically, a tension spring 16 positioned at the upper side of the guide tube 8 is coaxially arranged in the cylinder body 1.

In order to facilitate the opening of the sampling box 6 to be communicated with the sampling tube 3, the upper end of the sampling needle 2 is coaxially provided with a limit ring 17 positioned above the sampling tube 3, and the upper end of the sampling box 6 can be contacted with the lower end of the limit ring 17.

When the utility model is used, the initial state of the device is the state that the sampling box 6 is communicated with the sampling hole 5;

firstly, the cylinder body 1 is held by hand to drive the sampling needle 2 to be inserted into a tumor of a patient, after the sampling needle 2 is inserted into the tumor of the patient, tumor tissues of the patient are extruded into the sampling box 6 through the sampling hole 5, then the auxiliary plate 14 is pushed to drive the sliding block 13 to slide leftwards along the limiting groove 12 to a connecting port of the sliding way 11 and the limiting groove 12, the sliding block 13 drives the guide pipe 8 to rotate along the cylinder body 1, and the auxiliary plate 14 is provided with the anti-slip strip 15, so that the auxiliary plate 14 is conveniently pushed;

at the moment, under the action of the tension spring 16, the tension spring 16 drives the guide tube 8 to move upwards along the cylinder body 1, the guide tube 8 drives the sampling box 6 to slide upwards along the sampling needle 2, so that the sampling box 6 drives the cutter 7 to move upwards, and the cutter 7 cuts the tumor tissue extruded into the sampling box 6, so that the tumor tissue falls into the sampling box 6;
