[0035] In the biopsy needle excitation device provided in an embodiment of the present invention, the second excitation device 4 is arranged in the stroke of the first excitation device 3, and the second excitation device 4 can be excited by the first excitation device 3. Therefore, when in use, it is only necessary to manually excite the first excitation device 3 through the excitation button 2. The setting method of this excitation device satisfies the one-button excitation of the first excitation device 3 and the second excitation device 4, and also meets the excitation time difference requirement between the two.

[0036] like Figure 1As shown, the tail end of the first needle seat 32 is provided with a first groove 34, within which is provided at least one first straight rod 35 perpendicular to the bottom of the first groove 34. The front end of the first spring 33 is located within the first groove 34 and is sleeved on the first straight rod 35. The rear end of the first spring 33 abuts the first boss 31.

The first needle seat 32 excites the second excitation device 4 in the same way as the excitation button 2 excites the first excitation device 3 , that is, the excited first needle seat 32 moves toward the second boss 41 , and when it moves to the position of the second boss 41 , the second excitation device 4 is excited.

[0038] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the front end of the shell 1 is located at the bottom of the first winding hand position 392 and the second winding hand position 482 and is provided with an extension portion 11, and the first winding hand position 392 and the second winding hand position 482 slide along the upper surface of the extension portion 11; the front end of the extension portion 11 is the needle outlet end.

[0039] The first winding hand position 392 and the second winding hand position 482 are located at the front end of the housing 1 and arranged side by side. With the above arrangement, the key positions are arranged more reasonably and the pressing and winding operation is convenient.

[0040] In an embodiment of the present invention, the biopsy needle excitation device further includes a rear excitation portion 22 and a side excitation portion 23.

The side excitation portion 23 is located outside the housing 1, and the third connecting rod 24 is located inside the housing 1. The biopsy structure includes two excitation modes, namely rear excitation and side excitation. The excitation positions are located at different locations on the biopsy structure. When performing a biopsy operation, the appropriate excitation mode can be selected based on the convenience of the operation, further improving the convenience of the operation.

[0041] Figure 3 is a partial cross-sectional view of the biopsy needle excitation device provided by an embodiment of the present invention when not excited; Figure 4 FIG. 1 is a partial cross-sectional view of the biopsy needle excitation device provided in an embodiment of the present invention when it is excited. Figure 3 As shown, the first excitation device 3 and the second excitation device 4 are both in the winding state. In this state, the first spring 33 and the second spring 43 are compressed, the first clip 36 is engaged with the first card interface 37, and the second clip 46 is engaged with the second card interface 47. When the excitation operation is performed, you can choose to press the rear excitation part 22 or the side excitation part 23. Figure 4 As shown, the excitation button 2 excites the first excitation device 3, so that the first buckle 36 disengages from the first card interface 37. Under the action of the first spring 33, the first needle seat 32 moves toward the front end of the shell 1. After moving to the second boss 41, the first needle seat 32 excites the second excitation device 4, so that the second buckle 46 disengages from the second card interface 47. Under the action of the second spring 43, the second needle seat 42 moves toward the front end of the shell 1.

[0042] Figure 5 This is a front view of a fully automatic biopsy device provided by an embodiment of the present invention; Figure 6 This is a left side view of the fully automatic biopsy device provided by an embodiment of the present invention; Figure 7 : is a bottom view of the fully automatic biopsy device provided by an embodiment of the present invention. Figures 3 to 7 As shown, the fully automatic biopsy device includes an inner needle 5, an outer needle 6 and the above-mentioned biopsy needle excitation device; the inner needle 5 is connected to the first excitation device 3, and the outer needle 6 is connected to the second excitation device 4.

[0043] When the fully automatic biopsy device is in use, the first excitation device 3 drives the inner needle 5 to move, so that the inner needle 5 first enters the human lesion, and then the second excitation device 4 drives the outer needle 6 to move, so that the outer needle 6 enters the human lesion. The outer needle 6 cuts part of the sample and leaves it in the sampling groove of the inner needle 5, thereby achieving the purpose of biopsy.

[0044] According to the technical solution provided in this embodiment, by rationally arranging the excitation structure, the first excitation device 3 can be used to excite the second excitation device 4. During surgical operations, it is only necessary to drive the excitation button 2 to achieve the interval excitation of the first excitation device 3 and the second excitation device 4, making the operation of the biopsy needle structure simpler and avoiding situations such as failure to excite or misexcited due to the complicated structure. The biopsy needle excitation device is safer and more reliable.
