Specifically, an end cover 110 is fixedly mounted on the left side wall of the housing 100, and an end cover 110 is fixedly mounted on the left side of the top of the housing 100 The air pump 120 is provided with a tracheal channel 130 inside the housing 100, a stone taking channel 140 is opened in the middle of the inner wall of the housing 100, and the air outlet of the air pump 120 is connected to the tracheal channel 130 through the housing 100. The housing 100, the expansion assembly 200, the operation assembly 300, the stone grab assembly 400 and the stone crushing laser 500 are fixedly installed;
[0027] See again figure 1 with figure 2 The expansion assembly 200 has a piston pushing block 210, a spring 220, and an expansion plate 230. The expansion assembly 200 is installed on the right side of the housing 100. Specifically, the piston pushing block 210 is located at the right side of the inner wall of the tracheal channel 130. , The right end of the housing 100 is pin-connected to the expansion plate 230, the expansion assembly 200 includes a protective layer of the outer wall of the expansion plate 230, the protective layer is a rubber protective layer, the piston pushing block 210 A gasket is clamped on the outer wall, and the gasket is a rubber gasket. The bottom of the expansion plate 230 and the right side wall of the stone removal channel 140 are clamped with the spring 220;
[0028] See image 3 The operating assembly 300 has an adjusting end cover 310, a pull rod 320, an adjusting seat 330, and a connecting pipe 340. The operating assembly 300 is installed on the inner wall of the housing 100. Specifically, the middle of the left side wall of the adjusting end cover 310 is inserted into the Pull rod 320, the right end of the adjusting end cover 310 is screwed to the adjusting seat 330, the right side wall of the adjusting seat 330 is fixedly installed with the connecting pipe 340, and the side wall of the adjusting end cover 310 is evenly opened Twenty-two anti-skid grooves, the operating assembly 300 is used to fix and install the stone grab assembly 400;
[0029] See again image 3 The stone grab assembly 400 has a camera 410, a fixing seat 420, a claw 430 and an adjustment block 440. The stone grab assembly 400 is installed on the right side of the operating assembly 300. Specifically, the right side of the connecting pipe 340 is fixedly installed with the The fixing seat 420, the right side wall of the fixing seat 420 is fixedly installed with three claws 430, the middle part of the three claws 430 is clamped to the adjusting block 440, and the middle part of the right side wall of the adjusting block 440 is fixedly installed For the camera 410, the pull rod 320 is fixedly installed on the left side wall of the adjusting block 440;
[0030] See Figure 4 The lithotripsy laser 500 is used for crushing stones. Specifically, the lithotripsy laser 500 is fixedly installed on the right side wall of the housing 100, the camera 410 is electrically connected to the computer, and the lithotripsy laser 500 is electrically connected to the computer. Sexually connected with a lithotripsy host, which is a holmium laser lithotripsy;
[0031] In the specific process of use, when the present invention is needed, the housing 100 is first inserted into the patient’s urethra, the air pump 120 is used to inflate the inside of the tracheal channel 130, and the piston push block 210 is used to move to the right. Push to expand the expansion plate 230 to expand the urethra, and then use the lithotripsy laser 500 connected to the lithotripsy host of the holmium laser lithotripsy to crush the stones. Secondly, rotate and adjust the end cover 310. The distance between the end cover 310 and the adjusting seat 330 is enlarged, so that the pull rod 320 on the adjusting end cover 310 is moved to the left, thereby pulling the adjusting block 440 to move to the left, and the adjusting block 440 cooperates with the claw 430 Clamping to achieve expansion of the claw 430, clamp the gravel, and then release the gas in the air pump 120, and then the spring 220 pulls the expansion plate 230 to effectively clamp the stone, and finally pulls the adjusting seat 330 from the left side Remove the stone.
[0032] The above-mentioned spring 220, expansion plate 230, and claw 430 are not limited to the specific number described in this embodiment, and those skilled in the art can increase or decrease the number as needed, provided that the device can complete the stone grabbing.
[0033] Although the present invention has been described above with reference to the embodiments, without departing from the scope of the present invention, various modifications can be made thereto and the components therein can be replaced with equivalents. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any manner. The description of these combinations is not exhaustive in this specification. Because of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
