[0039] In the field of urology, the application of laser technology is increasingly widespread, especially in the treatment of kidney stones and prostate hyperplasia and other diseases. However, during the lithotripsy process, laser radiation can cause certain damage to the surrounding tissues, such as the renal pelvis and ureter. Therefore, for urologists, an effective method to evaluate and compare the extent of tissue damage caused by different laser technologies has become an important point.

[0042] Specifically, when the laser ablation efficiency of kidney tissue is observed and compared, the laser fiber needs to be positioned and mounted first. During installation, the laser fiber is inserted into the positioning sleeve 31. The distance between the laser fiber and the slice placement table 2 is adjusted. Then, the first locking member 32 is selected to compress the laser fiber in the positioning sleeve 31, thereby completing the positioning and mounting of the laser fiber.

[0043] Then, the slice tissue is placed on the slice placement table 2, and the slice tissue is adjusted to correspond to the laser fiber. At this time, the preliminary preparation of the experimental device is completed, and subsequent experiments can be carried out. The utility model provides an experimental device for comparing laser ablation efficiency, which can be used by medical staff to experimentally compare tissues, quantify and compare the tissue damage effects of different laser technologies in lithotripsy, and has important significance for guiding clinical practice and optimizing treatment plans.

[0044] In this embodiment, the overall structure of the positioning and mounting assembly 3 is further refined, and the positioning and mounting assembly 3 is detachably connected with the seat body 1.

[0045] Specifically, a through hole 11 is arranged on the seat body 1. The positioning and mounting assembly 3 further comprises a connecting member 33 and a second locking member 34. One end of the connecting member 33 is fixed with the positioning sleeve 31, and the other end is provided with a threaded hole 35. One end of the second locking member 34 penetrates through the through hole 11 and is threadedly connected with the threaded hole 35. A limiting boss 36 is arranged on the second locking member 34, and the limiting boss 36 compresses the seat body 1 to position and fix the connecting member 33.

[0046] Exemplarily, the detachable arrangement of the positioning and mounting assembly 3 enables the experimental device to have higher use flexibility. After the experiment is completed, the positioning and mounting assembly 3 can be integrally detached for cleaning and disinfection, and meanwhile, the device can be conveniently stored in a split manner. In order to improve the mounting stability of the laser fiber, two positioning and mounting assemblies 3 are correspondingly arranged at the upper portion of the slice placement table 2 in a vertical and spaced manner.

[0047] In this embodiment, more preferably, the seat body 1 is provided with at least two slice placement tables 2, and the number and position of the positioning and mounting assemblies 3 are correspondingly arranged with the slice placement tables 2.

[0048] In order to facilitate detailed description, in this embodiment, the slice placement table 2 is specifically provided with two, as shown in Figure 1 The arrangement of the plurality of slice placement tables 2 enables the experimental device to simultaneously perform experiments on two tissues, further optimizing the use flexibility of the device.

[0049] In this embodiment, the overall structure of the seat body 1 is further refined. The seat body 1 is arranged in an inverted T shape.
