[0003] Therefore, the embodiment of the present invention provides a thyroid puncture needle for capturing the entire nodule cells, which effectively avoids the problem of frequent needle replacement in traditional puncture methods, improves puncture efficiency and accuracy, and reduces the patient's postoperative pain and bleeding risk.

[0004] In order to solve the above problems, the utility model provides a thyroid puncture needle for grasping the entire nodule cell. The thyroid puncture needle includes: a shell, the shell is provided with a first accommodating cavity; a grasping component, the grasping component is slidably arranged in the first accommodating cavity, and the grasping component is provided with a grasping part; the grasping part is provided with a grasping space, the grasping part is elastically arranged, and the grasping of the entire nodule cell is achieved by sliding the grasping component; wherein, the entire nodule cell after being grasped is accommodated by the grasping space.

[0005] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting a first accommodating cavity in the shell, and by means of a sliding grasping component, the grasping part can grasp the entire nodule cell, and in this way, there is no need to replace the needle, it is only necessary to puncture the shell to the part where surgery is required, and then the work of grasping the cells is achieved by means of a sliding grasping component. This method is not only efficient, but also simple in structure. Moreover, since the sliding is performed through the first accommodating cavity set in the shell, the grasping accuracy after puncture is higher, there will be no deviation, and no secondary injury will be caused to the patient, thereby making the patient's operation process safer.

[0006] In an example of the present invention, the thyroid puncture needle further includes: a puncture portion, which is provided at one end of the shell near the grasping portion.

[0007] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the puncture part at one end of the shell close to the grasping part, the shell can be more conveniently punctured into the patient's surgical site, and this method makes puncture simpler, and there is no need to replace other equipment for puncture, making the surgical process simpler and more efficient. At the same time, puncture is also more convenient and quick, which facilitates the subsequent grasping of nodule cells and improves the accuracy and efficiency of grasping.

[0008] In an embodiment of the present invention, the shell is provided with a first opening, and the puncture portion further comprises: a plurality of tips, and the plurality of tips are circumferentially provided at the first opening.

[0009] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting a plurality of circumferentially arranged tips at the first opening, and using these tips to perform puncture, it is only necessary to rotate the shell to cut the skin and tissue through the multiple tips, so that the shell can enter the part requiring surgery more smoothly.
