[0010] In a preferred embodiment, the inner arc surface of the arc plate is provided with an arc-shaped groove, a measuring rod extending into the arc-shaped groove is fixedly connected to the left side surface of the mounting plate, an arc-shaped slot extending into the arc-shaped groove is provided on the front side of the arc plate, an indicator rod extending out of the front side of the arc plate is fixedly connected to the front side of the measuring rod, and a scale bar corresponding to the position of the arc-shaped slot is provided on the front side of the arc plate.

[0011] In a preferred embodiment, the upper surface of the base is provided with a rotating groove, and the inner bottom wall of the rotating groove is connected to a turntable via a damping rotating shaft. The upper surface of the turntable is fixedly connected to the lower surface of the first damping rotating seat.

[0012] The support direction of the bracket can be rotated and adjusted by using the turntable.

[0013] In a preferred embodiment, the lower surface of the base is provided with an installation mechanism, which includes a fixed plate fixedly connected to the bottom of the base by a bracket. The upper surface of the fixed plate is provided with an installation groove. A threaded rod is rotatably connected to the inner bottom wall of the installation groove. A threaded cylinder is threadedly connected to the surface of the threaded rod. An anti-slip pad is provided at the upper end of the threaded cylinder.

[0022] Secondly, during the rotation of the mounting plate, the mounting plate drives the measuring rod to move within the arc-shaped groove. The movement of the measuring rod drives the indicator rod to move synchronously within the arc-shaped groove. At this time, the angle of insertion of the biopsy needle or other tools can be measured by the position of the indicator rod and the scale bar, which provides convenience for subsequent medical work.

[0023] Thirdly: Rotating the operating lever drives the threaded rod to rotate, and the threaded cylinder moves upward under the rotation of the threaded rod until the threaded cylinder drives the anti-slip pad to abut against the bottom of the bed board, thus completing the installation of the bracket. After it is fixed, release the pull rod, and under the action of the spring, push the stop rod to reset, so that the limiting tooth at its end engages with the slot of the operating lever. This can fix the rotation angle of the operating lever and prevent the threaded cylinder from loosening its contact with the bed surface due to the rotation of the operating lever, thus improving its stability and firmness after fixing.

[0043] Reference Figure 4 and Figure 6 In a preferred embodiment, a reinforcing frame 23 is fixedly installed on the lower surface of the fixing plate 18. A stop rod 24 corresponding to the position of the operating rod 21 is slidably connected inside the reinforcing frame 23. A sliding opening is provided at the left end of the reinforcing frame 23. A pull rod 25 fixedly connected to the left end of the stop rod 24 is rotatably connected to the inner wall of the sliding opening. A spring 26 is sleeved on the surface of the pull rod 25.

The operating rod 21 can be limited by the setting of the stop rod 24, the limiting tooth and the slot 17.

[0044] Working principle: In use, place the base 1 and the fixing plate 18 on the edge of the bed. Pull the pull rod 25 to retract the abutment rod 24 into the reinforcing frame 23, so that the limiting tooth at the end of the abutment rod 24 separates from the slot 17 on the surface of the operating rod 21. Without the limiting tooth, rotate the operating rod 21 to drive the threaded rod 19 to rotate. The threaded cylinder 20 moves upward under the rotation of the threaded rod 19 until the threaded cylinder 20 drives the anti-slip pad to abut against the bed board, thus completing the installation of the bracket. After it is fixed, release the pull rod 25. Under the action of the spring 26, push the abutment rod 24 to reset, so that the limiting tooth at its end engages with the slot 17 of the operating rod 21. This can fix the rotation angle of the operating rod 21 and prevent the threaded cylinder 20 from loosening due to the rotation of the operating rod 21. Subsequently, through the first damping rotating seat 2 and the first damping rotating seat 2, the rotation angle of the operating rod 21 is fixed, thus preventing the threaded cylinder 20 from loosening its contact with the bed surface. The height of the mounting plate 11 can be adjusted by the telescopic rod 3, the second damping rotating seat 4, the second damping telescopic rod 5, the third damping rotating seat 6, and the crossbar 7. The mounting plate 11 can be rotated on the surface of the connecting rod 10 to adjust its angle until it is moved to the position corresponding to the external biopsy needle. Then, the handle of the biopsy needle is placed in the fixing clip 16 to complete the assembly and connection between the bracket and the biopsy needle, thereby achieving the purpose of auxiliary support and fixation of the biopsy needle. During this process, when the mounting plate 11 is rotated, the mounting plate 11 drives the measuring rod 12 to move in the arc-shaped groove. The movement of the measuring rod 12 drives the indicator rod 13 to move synchronously in the arc-shaped groove. At this time, the angle of biopsy needle insertion can be measured by the position of the indicator rod 13 and the scale bar 14, which provides convenience for subsequent medical work.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
