[0035] The utility model provides a laser fiber lithotripsy efficiency detection device, which uses an optical fiber driving device to drive the optical fiber to move, and performs a lithotripsy operation on the stones above the filter. When all the stones are broken and fall below the filter through the mesh of the filter, the duration of the entire lithotripsy process is calculated, and the operator can calculate the laser fiber lithotripsy efficiency according to the size of the stones, the mesh size and the lithotripsy time.

[0036] The laser fiber lithotripsy efficiency detection device provided by the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1 to Figure 4 The embodiment of the utility model provides a laser fiber lithotripsy efficiency detection device, which includes a first container 100, a supporting device, a filter 200, a fiber driving device and a fiber clamping device 300.

[0038] The first container 100 can be a water tank, which is used to contain physiological saline to simulate the human body fluid environment. The support device is arranged in the first container 100. The filter 200 is arranged on the support device, and the bottom of the filter 200 is open. The optical fiber driving device is arranged on one side of the first container 100, and the moving end of the optical fiber driving device is located above the filter 200, and the moving end of the optical fiber driving device can move in the X direction, the Y direction and the Z direction. The optical fiber clamping device 300 is arranged at the moving end of the optical fiber driving device, and the optical fiber clamping device 300 is used to clamp or loosen the optical fiber.

[0039] Before testing the efficiency of laser lithotripsy, first select a filter 200 of the required mesh size and place it on the support device, then select a stone of appropriate volume and place it on the filter 200. Then add physiological saline to the first container 100. The liquid level of the physiological saline needs to cover the top of the stone. The physiological saline is used to simulate the human body fluid environment. The physiological saline can also cool the filter 200, the support frame, etc. during the laser lithotripsy process. Then connect the laser entry end of the optical fiber to the laser device, and the part of the optical fiber close to the laser emission end is clamped on the optical fiber clamping device 300. The laser emission end extends below the liquid level and is located above the stone.

[0040] When testing the efficiency of laser lithotripsy, the laser device is started, and the laser beam is emitted to the surface of the stone through the optical fiber. The laser emission end is driven by the optical fiber driving device to move along the X, Y and Z directions to act on different positions of the stone. The crushed stones with a particle size smaller than the mesh size will fall below the filter 200 through the mesh of the filter 200.

[0041] When all the stones fall under the filter 200, the time for stone crushing is calculated. The experimenter can calculate the current laser fiber stone crushing efficiency based on the stone size, mesh size and stone crushing time, thereby achieving the effect of quantifying the laser fiber stone crushing efficiency.

[0042] In some embodiments of the present invention, the top of the first container 100 is open, and the size of the open area on the top of the first container 100 may be 10 cm×10 cm×10 cm.

[0043] In some embodiments of the present invention, in order to observe the stone crushing process, the first container 100 may be made of a transparent material, such as glass.

[0044] Alternatively, the first container 100 may be made of an opaque material such as metal, but a first window is provided on the first container 100 , and the opening position of the first window needs to ensure that the experimenter can observe the stones on the top of the filter 200 through the first window.

[0045] In some embodiments of the present invention, the supporting device may include a supporting frame, the edge of the supporting frame is connected to the inner wall of the first container 100 , and the middle part of the supporting frame is used to support the bottom edge of the filter screen 200 .

[0046] Specifically, the filter 200 may be a circular filter, and the support frame may include a support arm 411 and a support ring 412, wherein the inner diameter of the support ring 412 is smaller than the outer diameter of the filter 200. The support arm 411 is radially connected to the outer side of the support ring 412 and extends radially along the support ring 412. The end of the support arm 411 away from the support ring 412 is used to connect with the inner wall of the first container 100. After connection, the support ring 412 may be located at the center of the first container 100, and the support ring 412 may be located in the middle of the first container 100 in the up-down direction. When in use, the filter 200 is placed on the top of the support ring 412. At this time, the bottom of the filter 200 is open, so that the crushed stones can fall through the filter 200.

[0047] Furthermore, a retaining ring may be provided on the top of the support ring 412, the outer diameter of the retaining ring being equal to the outer diameter of the support ring 412, the retaining ring extending upward, and the inner diameter of the retaining ring being equal to the outer diameter of the filter screen 200. When the filter screen 200 is placed on the support ring 412, the filter screen 200 is located inside the retaining ring, and the retaining ring can limit the filter screen 200 from moving in its own radial direction.

[0048] In some embodiments of the utility model, the support device may further include a second container 420, which is used to be arranged in the middle of the support frame, and the top of the second container 420 is open for the laser emitting end of the optical fiber to extend therein, and the stone can be placed in the second container 420. At least the bottom of the second container 420 is connected to the first container 100, so that the physiological saline in the first container 100 can enter the second container 420. The filter 200 is detachably arranged in the second container 420, and is used to support and filter the crushed stones. The filter 200 is detachably connected to the second container 420, and the filter 200 with different mesh sizes can be replaced according to different experimental requirements.

[0049] Specifically, the second container 420 can be a test tube with an open top and bottom. A flange 421 can be provided on the outside of the test tube and near the middle position of the test tube along the axial direction. The outer diameter of the test tube is slightly smaller than the inner diameter of the support ring 412. In this way, the test tube can be inserted into the support ring 412, and the flange 421 is supported on the top of the support ring 412, thereby achieving the fixation of the test tube.

[0050] A groove 422 is further provided inside the test tube, and the inner diameter of the groove 422 is equal to the outer diameter of the filter screen 200 . The filter screen 200 can be fixed in the test tube through the groove 422 .

[0051] Alternatively, the test tube may be open only at the top, and a water-permeable hole may be provided at any position of the test tube below the flange 421, so that the physiological saline in the first container 100 can enter the test tube.

[0052] In some embodiments of the present invention, in order to observe the stone crushing process, the second container 420 may be made of a transparent material, such as glass.

[0053] Alternatively, the second container 420 may be made of an opaque material such as metal, but a second window needs to be opened on the second container 420 , and the second window needs to be opened at a position that allows the experimenter to observe the stones above the filter 200 through the second window.

[0054] Of course, when the first container 100 is also made of an opaque material and has a first window, the positions of the first window and the second window need to enable the experimenter to observe the stones above the filter 200 through the first window and the second window.

[0055] In some embodiments of the present invention, the optical fiber driving device includes an X-axis moving component 510 , a Y-axis moving component 520 , and a Z-axis moving component 530 .

[0056] The X-direction moving assembly 510 may include a first frame, a first stepper motor, a first lead screw and a first slider. The first frame may be arranged on one side of the first container 100. The first lead screw is rotatably connected to the first frame and extends along the X direction, which may be a left-right direction. The first slider is slidably connected to the first frame, and the first frame may limit the rotation of the first slider. The first slider is threadedly connected to the first lead screw. The first stepper motor is arranged on the first frame, and the rotating shaft of the first stepper motor is transmission-connected to the first lead screw. The first stepper motor drives the first lead screw to rotate, thereby driving the first slider to move along the X direction.

[0057] The Y-direction moving assembly 520 may include a second frame, a second stepper motor, a second lead screw and a second slider. The second frame is connected to the first slider and moves with the first slider. The second lead screw is rotationally connected to the second frame, and the second lead screw extends along the Y direction, which can be a front-back direction. The second slider is slidably connected to the second frame, and the second frame can limit the rotation of the second slider. The second slider is threadedly connected to the second lead screw. The second stepper motor is disposed on the second frame, and the rotating shaft of the second stepper motor is transmission-connected to the second lead screw. The second stepper motor drives the second lead screw to rotate, thereby driving the second slider to move along the Y direction.

[0058] The Z-axis moving assembly 530 may include an electric push rod, which is connected to the second slider and moves with the second slider. The electric push rod extends downward and retracts upward.

[0059] In some embodiments of the present invention, the side length of the mesh of the filter screen 200 may be 1 mm, 2 mm, 3 mm, 4 mm or 5 mm.
