[0002] A biopsy needle is a medical device suitable for various organs, including the kidneys, liver, lungs, breast, thyroid, prostate, pancreas, testes, uterus, ovaries, and the body surface. It can be used for biopsy of pyramidal tumors and tumors of unknown origin, and is currently one of the most widely used instruments in clinical practice. The puncture biopsy needle belongs to the soft tissue biopsy instrument category. It is used for ultrasound-guided puncture biopsies and interventional treatments, allowing for minimally invasive sampling of lesions and providing valuable preoperative diagnostic information for clinicians.

[0037] A flattening device for biopsy needle shaft includes a feeding device 10 and a pressing device 20.

[0038] The material conveying device 10 includes a feeding mechanism 11, a sliding mechanism 12 connected to the feeding mechanism 11, and a fixing mechanism 13 connected to the sliding mechanism 12. The feeding mechanism 11 is located above the sliding mechanism 12, and the fixing mechanism 13 is located at the end of the sliding mechanism 12. The bottom of the feeding mechanism 11 is provided with a discharge port 11A, which is connected to the sliding mechanism 12. The feeding mechanism 11 is semi-circular in shape. The sliding mechanism 12 includes a slide 121, a housing 122 connected to the slide 121, and a fixing mechanism 13 connected to the housing 121. The guard plate assembly 123 of 2 has an arc-shaped slide 121. The outer shell 122 is connected to the feeding mechanism 11. The guard plate assembly 123 includes two guard plates 1231, which are symmetrically arranged. The slide 121 is located between the two guard plates 1231. At least one set of support mechanisms 14 is also provided below the feeding mechanism 12. The set of support mechanisms 14 includes three support rods 141. It should be noted that one end of the support rod 141 is connected to the feeding mechanism 12, and the other end is fixed to the worktable 24.

[0039] The material-fixing mechanism 13 includes a material-fixing trough 131, a baffle 132 connected to the material-fixing trough 131, and a tilting and unloading assembly 133 connected to the material-fixing trough 131. The material-fixing trough 131 is a strip-shaped trough. The bottom of the material-fixing trough 131 is provided with a flattening support part 1311. Specifically, the bottom of the material-fixing trough 131 is provided with a first opening 131A. The flattening support part 1311 includes a flattening support column 1312. The flattening support column 1312 passes through the first opening 131A from the outside to the inside and is flush with the inner surface of the bottom of the material-fixing trough 131. The baffle... A contact sensing component 1321 is connected to 132 to detect whether the biopsy needle has reached the preset position. Specifically, if the biopsy needle is detected by the contact sensing component 1321, the biopsy needle has reached the preset position, and the flattening position of the biopsy needle falls on the flattening support 1311. Conversely, if the biopsy needle has not reached the preset position, the flattening position of the biopsy needle does not fall on the flattening support 1311. It should be noted that one end of the flattening support column 1312 is engaged with the first opening 131A, and the other end is fixed to the worktable 24.

[0040] The bottom of the solid material tank 131 is also provided with a second opening 131B. The flipping and feeding assembly 133 includes a connecting plate 1331, a flipping block 1332 connected to the connecting plate 1331, and a blocking block 1333 connected to the flipping block 1332. The connecting plate 1331 is fixed to the outer side wall of the bottom of the solid material tank 131. The flipping block 1332 drives the blocking block 1333 to flip. The blocking block 1333 cooperates with the second opening 131B. Furthermore, the blocking block 1333 is fan-shaped to avoid interference caused by the blocking block 1333 cooperating with the second opening 131B. Specifically, when the blocking block 1333 cooperates with the second opening 131B, the biopsy needle stops feeding, the blocking block 1333 separates from the second opening 131B, and the biopsy needle feeds into the inside of the material collection device through the second opening 131B. The pressing device 20 includes a pressing device 21, a connector 22 connected to the pressing device 21, and a pressing head 23 connected to the connector 22. The connector 22 is connected to the telescopic end of the pressing device 21. The connector 22 is provided with a connecting through hole 22A. The connecting part of the pressing head 23 is provided with a connecting groove 231. The connecting part of the pressing head 23 is also provided with a connecting through hole 22A, and the connecting through hole 22A passes through the connecting groove 231. The connecting through hole 22A on the connecting part of the pressing head 23 corresponds to the connecting through hole 22A on the connector 22. It should be noted that when the connecting through hole 22A on the connecting part of the pressing head 23 corresponds to the connecting through hole 22A on the connector 22, the connection between the pressing head 23 and the connector 22 is completed by passing bolts through each connecting through hole 22A and then using nuts to thread the bolts.

[0041] Here, the flattening device for the biopsy needle shaft includes a feeding device 10 and a pressing device 20. The feeding device 10 includes a feeding mechanism 11, a sliding mechanism 12 connected to the feeding mechanism 11, and a fixing mechanism 13 connected to the sliding mechanism 12. The feeding mechanism 11 is located above the sliding mechanism 12, and the fixing mechanism 13 is located at the end of the sliding mechanism 12. The bottom of the feeding mechanism 11 is provided with a discharge port 11A, which is connected to the sliding mechanism 12. At least one set of support mechanisms 14 is also provided below the sliding mechanism 12. The fixing mechanism 13 includes a fixing mechanism. The device includes a groove 131, a baffle 132 connected to the solid material groove 131, and a flipping and unloading assembly 133 connected to the solid material groove 131. The bottom of the solid material groove 131 is provided with a flattening support part 1311. The pressing device 20 includes a pressing device 21, a connector 22 connected to the pressing device 21, and a pressing head 23 connected to the connector 22. The connector 22 is connected to the telescopic end of the pressing device 21. Under the action of the baffle 132, the stability of the biopsy needle shaft is improved during the flattening process of the biopsy needle shaft, thereby improving the product qualification rate.

[0042] To facilitate understanding, the working principle of this application is further described as follows: For the flattening device used for biopsy needle shafts, firstly, based on the length, diameter, and flattening position of the biopsy needle, a feeding device 10 corresponding to the biopsy needle specifications is selected. During operation, multiple biopsy needles are directly placed through the feeding mechanism 11, with the flattened portion of the biopsy needle facing the flattening support 1311. After the pressure head 23 of the pressing device 20 is positioned directly above the flattening support 1311, a single biopsy needle falls through the discharge port 11A to the sliding mechanism 12. Under its own weight and the action of the slide rail 121, the single biopsy needle slides to the fixing mechanism 13. Under the action of the guard plate 1231 of the fixing mechanism 13, the single biopsy needle cannot undergo significant deformation. The oscillation is only slight and within the error range. Under the action of the baffle 132, the part of the biopsy needle to be flattened is placed directly above the flattening support 1311, and one end of the single biopsy needle is in contact with the contact sensing component 1321. The contact sensing component 1321 sends a signal to the external control switch, which controls the pressure head 23 of the pressing device 20 to press down, thereby completing the flattening of the biopsy needle shaft. After that, the flipping block 1332 drives the blocking block 1333 to rotate, causing the blocking block 1333 to separate from the second opening 131B. The biopsy needle falls at an angle through the second opening 131B under its own gravity until it falls into the material collection device located below the second opening 131B.
