[0002] Liver puncture is the abbreviation of liver puncture biopsy. Patients usually need local anesthesia and use negative pressure liver puncture suction one-second puncture technology. Some diseases are difficult to diagnose, such as autoimmune hepatitis, chronic hepatitis, primary biliary cirrhosis, etc. The clinical diagnosis of diseases often has certain deviations. Only pathological diagnosis is truly reliable. Liver biopsy needs to be combined with clinical symptoms. Therefore, liver biopsy can provide important clues for the diagnosis of liver disease.

[0003] The puncture point of liver puncture may vary according to the specific conditions of the patient. Currently, liver puncture usually requires medical staff to confirm the puncture point and then hold the puncture tool to perform puncture sampling. The puncture operator needs to be highly focused.

[0033] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0034] Please also read Figure 1-Figure 3 This embodiment provides a liver disease puncture stent, including a fixed frame assembly 1, a moving block 2, a vertical axis rotation assembly 3, a longitudinal axis rotation assembly 4, a horizontal axis rotation assembly 5, a locking assembly 6 and a puncture tool 7.

[0035] The moving block 2 is slidably disposed on the fixed frame assembly 1 and can be fixed. It should be understood that the fixed frame assembly 1 is disposed on the bed, and the moving block 2 can slide to both sides of the bed and can be fixed at the desired position after being moved to the desired position.

[0036] In other schemes, the fixing frame assembly 1 includes a fixing frame body 11 and a threaded column 12; the fixing frame body 11 is provided with a plurality of threaded holes 111, and the threaded column 12 is provided with a plurality of threaded holes 111 and corresponds one to one with the threaded holes 111; the moving block 2 is slidably connected to the fixing frame body 11, and the moving block 2 is provided with a threaded groove 21, and the threaded column 12 can be screwed with the threaded hole 111 and the threaded groove 21 at the same time.

[0037] The vertical axis rotation assembly 3 is rotatably arranged on the moving block 2, the longitudinal axis rotation assembly 4 is rotatably arranged on the vertical axis rotation assembly 3, the transverse axis rotation assembly 5 is rotatably arranged on the longitudinal axis rotation assembly 4, and the puncture tool 7 is detachably arranged on the transverse axis rotation assembly 5. It should be understood that the rotation of the vertical axis rotation assembly 3 can drive the longitudinal axis rotation assembly 4 and the transverse axis rotation assembly 5 to rotate around the vertical axis; the rotation of the longitudinal axis rotation assembly 4 can drive the transverse axis rotation assembly 5 to rotate around the longitudinal axis; the rotation of the transverse axis rotation assembly 5 can drive the puncture tool 7 to rotate around the transverse axis. By rotating the required rotating shafts respectively, the puncture assembly can be adjusted to the required angle. As a preference, the axis of the vertical axis rotation assembly 3 passes through the centers of the longitudinal axis rotation assembly 4, the transverse axis rotation assembly 5 and the puncture tool 7 at the same time. It should also be understood that the puncture tool 7 arranged on the transverse axis rotation assembly will not affect its own puncture function, that is, the puncture tool 7 arranged on the transverse axis rotation assembly can be extended and inserted into the patient's body through the operation of the operator.

[0038] The locking assembly 6 corresponds to the vertical axis rotation assembly 3, the longitudinal axis rotation assembly 4 and the transverse axis rotation assembly 5 one by one, and can restrict their rotation by shortening them. It should be understood that shortening the locking assembly 6 can respectively hinder the rotation of the vertical axis rotation assembly 3, the longitudinal axis rotation assembly 4 and the transverse axis rotation assembly 5.

[0039] In the present device, since the puncture tool 7 is arranged on the horizontal axis rotating assembly 5, the horizontal axis rotating assembly 5 is rotatably connected to the longitudinal axis rotating assembly 4, the longitudinal axis rotating assembly 4 is rotatably connected to the vertical axis rotating assembly 3, and the vertical axis rotating assembly 3 is rotatably connected to the moving block 2, the puncture tool 7 can be rotated along the vertical axis, longitudinal axis and horizontal axis with the moving block 2 as the reference point, meeting the puncture requirements at any angle, and the moving block 2 is slidably arranged on the fixed frame assembly 1, so that the puncture tool 7 can be placed at a desired position at a desired angle, and because the puncture tool 7 is arranged on the horizontal axis rotating assembly 5, the puncture tool 7 will not shake during puncture, thus avoiding shaking during puncture to affect the patient.

[0040] When performing puncture, the puncture tool 7 must first be moved to the desired position, and then the angle must be adjusted. When performing puncture, the puncture tool 7 must be pushed into the human body. If the moving block 2 is only moved to the desired position and the locking is forgotten, it may cause positional deviation and cause accidental damage. In order to avoid forgetting to lock the moving position, in other schemes, a locking mechanism 8 is also provided; a slide groove 22 is also provided on the moving block 2, and the slide groove 22 is connected to the thread groove 21; the locking mechanism 8 can be slidably arranged on the slide groove 22, and can limit the extension of the locking assembly 6 before the threaded column 12 squeezes the locking mechanism 8, so that the locking assembly 6 remains in a shortened state. By setting the locking mechanism 8, the locking mechanism 8 can keep the locking assembly 6 in a shortened state before the moving block 2 is unlocked. Since the locking assembly 6 can limit the rotation of each axis in the shortened state, and the puncture angle usually needs to be adjusted, the operator can promptly find that the movement is not locked after finding that the rotation is blocked, thereby avoiding sliding during puncture.

[0041] In other schemes, the locking mechanism 8 includes a pressing plate 81, a pressing spring 82, a sliding wedge block 83, a driving block 84, a driving spring 85 and an abutment assembly 86; the pressing plate 81 is liftably arranged in the slide groove 22 through the pressing spring 82 and is opposite to the threaded groove 21; the sliding wedge block 83 is slidably connected in the slide groove 22, one end of the driving block 84 is liftably arranged in the slide groove 22 through the driving spring 85, and the other end is located outside the slide groove 22 and connected to the abutment assembly 86; the driving spring 85 is in a stretched state, and through the driving block 84, the abutment assembly 86 simultaneously squeezes the locking assembly 6, and the descent of the pressing plate 81 can squeeze the sliding wedge block 83, so that the sliding wedge block 83 lifts the driving block 84. It should be understood that the slide groove 22 is an L-shaped slide groove 22 rotated 90 degrees to the right, the drive spring 85 is located at the leftmost side and connected to the outside, and the bottom end of the drive block 84 abuts against the other side of the L-shaped slide groove 22, so that the drive spring 85 is in a stretched state. In this state, the abutment assembly 86 continues to squeeze the locking assembly 6 to keep the locking assembly 6 in a shortened state.

[0042] In other embodiments, the abutment assembly 86 includes a connecting plate 861 and an abutment block 862; the connecting plate is connected to the driving block 84, and the abutment block 862 corresponds to the locking assembly 6 one by one, and can squeeze the locking assembly 6 before the sliding wedge block 83 lifts the driving block 84, so that the locking assembly 6 remains in a shortened state. In this embodiment, the connecting plate 861 is Z-shaped, and is connected to each abutment block 862 at the same time. The abutment block 862 is in the extension direction of the locking assembly 6 and limits its extension, so that it remains in a shortened state.

[0043] In other embodiments, the vertical axis rotation assembly 3 includes a vertical axis 31 and a rotating bracket 32; the vertical axis 31 is connected to the moving block 2, the rotating bracket 32 ​​is rotatably connected to the moving block 2, the horizontal axis rotation assembly is rotatably disposed on the rotating bracket 32, and the locking assembly 6 is disposed on the rotating bracket 32 ​​and can limit the rotation of the rotating bracket 32. It should be understood that the vertical axis 31 does not rotate, and the rotating bracket 32 ​​rotates around the vertical axis 31.

[0044] In other embodiments, the longitudinal axis rotation assembly 4 includes a longitudinal axis 41 and a rotating box 42; the longitudinal axis 41 is rotatably inserted into the rotating bracket 32, the rotating box 42 is fixed on the longitudinal axis 41, the transverse axis rotation assembly is rotatably disposed in the rotating box 42, and the locking assembly 6 is disposed on the rotating bracket 32 ​​and can limit the rotation of the longitudinal axis 41.

[0045] In other schemes, the transverse axis rotation assembly includes a transverse axis 51 and a rotating plate 52; the transverse axis 51 is arranged in the rotating box 42, the rotating plate 52 is fixed on the transverse axis 51, and a puncture is provided on the rotating plate 52; the locking assembly 6 is arranged on the rotating box 42, and can limit the rotation of the transverse axis 51.

[0046] In other embodiments, the locking assembly 6 includes a rotating ring 61, a telescopic plate 62 and a locking column 63; the rotating ring 61 is coaxially fixed to the vertical rotating shaft 31, the longitudinal rotating shaft 41 and the transverse rotating shaft 51, respectively, and a plurality of limiting grooves 611 are axially eccentrically provided on the rotating ring 61; the telescopic plate 62 is respectively provided on the rotating bracket 32 ​​and the rotating box 42, and the locking column 63 is provided on the telescopic plate 62 and can be inserted into the limiting groove 611, and the abutment block 862 can limit the extension of the telescopic plate 62 and keep the locking column 63 inserted into the limiting groove 611. When the telescopic plate 62 is in a shortened state, the locking column 63 is in a state of being inserted into the limiting groove 611.

[0047] The liver disease puncture stent can fix the puncture tool at multiple angles and positions to prevent shaking during puncture.
