Specific embodiments

[0025] In order to make the utility model's purpose, technical scheme and advantage more clearly, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the utility model.

[0026] Referring to Figures 1-4 The utility model provides oral cavity cancer puncture sampling device, including fixed head 1, fixed head 1 is fixed with guide needle tube 2, the sliding arrangement of guide needle tube 2 in sampling needle 4 is set up, and cutting groove 5 is set up in sampling needle 4, and rotating assembly 8 is set up on the surface of sampling needle 4 for rotating sampling needle 4;

[0027] Gas spring rod 7 is set up between rotating assembly 8 and fixed head 1, and the extension direction of gas spring rod 7 is set along the length direction of guide needle tube 2.

[0028] As optional implementation, the surface of fixed head 1 is symmetrically provided with two fixed rings 3, and the index finger and middle finger can be inserted into the two fixed rings 3 respectively when using the device, so that the stability of holding the device can be improved.

[0029] Rotating assembly 8 includes fixed plate 9 and thread wheel 12, and fixed plate 9 is rotatably arranged on sampling needle 4, and torsional spring 11 is sleeved on the surface of sampling needle 4, and the two ends of torsional spring 11 are fixed with sampling needle 4 and fixed plate 9 respectively, and thread wheel 12 is fixed on sampling needle 4, and pull rope 13 is wound on the surface of thread wheel 12, one end of pull rope 13 is fixed on thread wheel 12, and the other end is fixed with pull head 14, pull rope 13 is pulled by pull head 14, so that pull rope 13 is unfolded, and sampling needle 4 can be rotated by the cooperation of pull rope 13 and thread wheel 12.

[0030] The two ends of gas spring rod 7 are fixed with fixed head 1 and fixed plate 9 respectively, and gas spring rod 7 can drive fixed plate 9 to reset, and at the same time, gas spring rod 7 can position fixed plate 9, prevent fixed plate 9 from rotating, after pull rope 13 is loosened, torsional spring 11 can reversely rotate sampling needle 4, so that thread wheel 12 is wound on pull rope 13 again, and it is convenient to operate rotating assembly 8 next time.

[0031] The fixed plate 9 is fixed with a fixed sleeve 10, the pull rope 13 passes through the fixed sleeve 10, and the pull head 14 is in surface contact with the fixed sleeve 10. The fixed sleeve 10 and the pull head 14 can guide the pull rope 13 and prevent the pull rope 13 from falling off the line wheel 12.

[0032] The sampling needle 4 is rotationally arranged with a pressing block 6 close to one end of the fixed ring 3. The thumb pushes the pressing block 6, thereby pushing the sampling needle 4. The thumb is not directly pressed against the end of the sampling needle 4, the finger is not uncomfortable, and the pressing block 6 does not rotate with the sampling needle 4 after being in contact with the thumb.

[0033] The end of the sampling needle 4 away from the pressing block 6 is arranged as a tapered sharp head. The range of the trajectory of the tapered sharp head when rotating is small, thereby reducing the trauma to the patient when the sampling needle 4 rotates.

[0034] The cutting groove 5 is designed as a blade surface 15 on both sides. The blade surface 15 makes the cutting groove 5 more easily cut the lesion tissue of the patient.

[0035] With the above structure, the guide needle tube 2 is inserted into the patient's body, and then the sampling needle 4 is pushed to make the sampling needle 4 slide along the guide needle tube 2 until the cutting groove 5 of the sampling needle 4 is inserted into the lesion tissue, so that the lesion tissue fills into the cutting groove 5. Then the sampling needle 4 is rotated by rotating the rotating assembly 8, the sampling needle 4 drives the cutting groove 5 to rotate one circle to complete the incision of the lesion tissue, so that the tissue in the cutting groove 5 is completely separated from other tissues. Finally, the sampling needle 4 is loosened, the air spring rod 7 drives the sampling needle 4 to reset, so that it is retracted into the guide needle tube 2. Finally, the guide needle tube 2 is pulled out of the patient's body by the fixed head 1, and the sampling is completed.

[0036] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
