Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a urethra endoscope device and a urethra dilation device. Background Art

[0002] Urethral stricture is a urinary tract disease characterized by narrowing of the urethra, which impairs urine flow. It has numerous causes, including traumatic injuries such as straddle injuries and pelvic fractures, which are common. Other iatrogenic factors include transurethral surgical procedures (such as transurethral resection of the prostate) and intraurethral instrumentation.

[0003] Urethral dilation is a treatment option for patients with urethral strictures. Currently, urologists rely primarily on experience and skill to perform urethral dilation using a urethral probe.

[0016] In the present invention, through the above design, when using this device, first insert the hexagonal wrench into the hexagonal slot, and then rotate the hexagonal wrench to drive the screw to rotate. At this time, since the external threads on both sides of the outer wall of the screw are arranged in opposite directions, the screw will drive the two sliders to move toward each other when it rotates. When the two sliders move toward each other, the two cones will be driven to fit together through the connecting rod. Then, lubricant is applied to the outer walls of the two cones, and the small-diameter ends of the two cones are inserted into the patient's pudendal urethra with auxiliary medical tools. After insertion, the screw is driven to rotate in the opposite direction by rotating the hexagonal wrench, so that the two cones are moved away from each other to open the urethra, in preparation for the insertion, peeping and expansion of the subsequent inserter. Of course, the controller needs to be explained here. By setting the controller, the three electric push rods are started separately. The extension and contraction of each piston barrel will cause the pistons in piston barrel one, piston barrel two and piston barrel three to move left and right through the push-pull rod, thereby creating positive and negative pressure states in the inner cavities of piston barrel one, piston barrel two and piston barrel three. Based on this, after the lubricant is filled in the lubricating liquid tank, under the one-way check action of the one-way valve one and the one-way valve two, when the pressure in piston barrel three is negative, the lubricant in the lubricating liquid tank will be drawn into piston barrel three through the pipeline. When the pressure in piston barrel three is positive, the lubricant just drawn in will be discharged through the connecting pipe. Combined with the functions of the expander and controller described in the previous paragraph, when the expander opens the patient's pudendal urethra, the medical staff first connects the liquid pipe to the connecting pipe at the left end of piston barrel three, and then connects the data cable to the data interface on the side of the signal converter. The needle is then pulled out of the urethra and into the urethra, and then the needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. The needle is pulled out of the urethra and then into the urethra. During the process, the endoscope lens at the left end of the forward part will transmit the image data information of the urethral opening to the forward part through the data cable, and the signal from the forward part will be converted into a video signal and played on the monitor to provide video image guidance for the urethral dilation surgery. When the forward part moves to the position of the urethra that needs to be dilated, the electric push rod on the right side of the piston cylinder 2 is started to extend to form a positive pressure environment for the inner cavity of the piston cylinder 2, so that the airbag is inflated through the trachea connected to the connecting tube, and then the surrounding expansion plates are pushed outward to dilate the urethra at that location.

Sliders 12 are slidably installed on both sides of the top of the track plate 11. Sliders 12 are opened on both sides of the top of the track plate 11 to match the slides 12. The two slides 12 are slidably installed in the slides on both sides. The inside of the track plate 11 is rotatably installed with a screw rod 15 with opposite external threads on both sides of the outer wall. The screw rod 15 is threadedly connected to the two slides 12. The end of the screw rod 15 located on the outer wall of the track plate 11 is provided with a hexagonal groove 16. The top of the slide 12 is fixedly installed with a connecting rod 13, and the inner side of the top of the connecting rod 13 is fixedly installed with a cone 14.

[0025] By setting the expander 1, when using this device, first insert the hexagonal wrench into the hexagonal slot 16, and then rotate the hexagonal wrench to drive the screw 15 to rotate. At this time, since the external threads on both sides of the outer wall of the screw 15 are arranged in opposite directions, the screw 15 will drive the two sliders 12 to move toward each other when it rotates. When the two sliders 12 move toward each other, the two cones 14 will be driven to fit together through the connecting rod 13. Then, lubricant is applied to the outer walls of the two cones 14, and then the small-diameter ends of the two cones 14 are inserted into the patient's pudendal urethral opening with the help of auxiliary medical tools. After insertion, the screw 15 is driven to rotate in the opposite direction by rotating the hexagonal wrench, so that the two cones 14 are moved away from each other to open the urethral opening, in preparation for the subsequent insertion, peeping and expansion of the inserter 3.

[0026] Reference Figure 1 、 3 The controller 2 includes a support platform 201, a signal converter 202 is fixedly installed on the top right side of the support platform 201, a display 203 is set above the signal converter 202, and a data interface 204 is set on the side wall of the signal converter 202.

The left end of the piston cylinder three 208 is respectively fixedly connected with a one-way valve one 211 and a one-way valve two 212. The one-way valve one 211 allows the medium to flow toward the piston cylinder three 208, and the one-way valve two 212 allows the medium to flow away from the piston cylinder three 208. The outer end of the one-way valve one 211 is connected to the lubricating liquid tank 210 through a pipeline, and the left end of the one-way valve two 212 is fixedly connected with a connecting pipe 213. The left ends of the piston cylinder one 206 and the piston cylinder two 207 are also fixedly connected with a connecting pipe 213.

[0027] By setting up a controller 2, starting the three electric push rods 209 to extend and contract respectively will drive the pistons in piston cylinder 1 206, piston cylinder 2 207 and piston cylinder 3 208 to move left and right through the push-pull rods, thereby creating positive and negative pressure states in the inner cavities of piston cylinder 1 206, piston cylinder 2 207 and piston cylinder 3 208. Based on this, after the lubricant is filled in the lubricating liquid tank 210, under the one-way check action of the one-way valve 1 211 and the one-way valve 2 212, when the pressure in piston cylinder 3 208 is negative, the lubricant in the lubricating liquid tank 210 will be drawn into piston cylinder 3 208 through the pipeline. When the pressure in piston cylinder 3 208 is positive, the lubricant just drawn in will be discharged through the connecting pipe 213.

[0028] Reference Figure 1 、 3 4. The inserter 3 includes a plug 301. A forward portion 302 is provided on the left side of the plug 301. A circle of receding portions 303 are provided on the right side of the plug 301. Both the forward portion 302 and the receding portion 303 are of arc-shaped design. The outer wall of the left end of the forward portion 302 is provided with circumferential leakage holes 304. A tail block 308 is fixedly installed on the right side of the forward portion 302. A liquid pipe 305 connected to the leakage hole 304 is fixedly connected to the right side of the tail block 308. An endoscope head 306 is fixedly installed on the left center of the forward portion 302. The right side of the tail block 308 is fixedly connected to the liquid pipe 305 connected to the leakage hole 304. A data line 307 electrically connected to the endoscope lens 306 is connected, airbags 309 are fixedly mounted on all four outer surfaces of the tail block 308, an expansion plate 310 is fixedly mounted on the outer end of the airbag 309, and a receiving groove adapted for the airbag 309 and the expansion plate 310 is provided on all four outer surfaces of the tail block 308. An air pipe 311 connected to the airbag 309 is fixedly connected to the right side of the tail block 308, and a rubber hose 312 is fixedly connected to the right side of the tail block 308. The outer periphery of the rubber hose 312 is fixedly sleeved with several hard sleeves 313 distributed linearly and with gaps between them.

[0029] By setting the expander 1, controller 2 and inserter 3, combined with the functions of the expander 1 and controller 2 described in the previous paragraph, when the expander 1 opens the patient's pudendal urethra, the medical staff first connects the liquid tube 305 to the connecting tube 213 at the left end of the piston cylinder 3 208, and then connects the data line 307 to the data interface 204 on the side of the signal converter 202, and then respectively connects the air tube 311 and the hose 312 to the connecting tube 213 at the left end of the piston cylinder 1 206 and the piston cylinder 2 207. After this step is completed, first start the electric The push rod 209 extends, and at this time the piston cylinder 1 206 inflates the rubber tube 312, so that the rubber tube 312 becomes straight and hard in conjunction with the hard sleeve 313 fixed on its outer periphery. Then the medical staff holds the rubber tube 312 and inserts the forward part 302 on the left side of the plug 301 into the patient's urethra opened by the cone cylinder 14. During the insertion process, the medical staff activates the electric push rod 209 on the right side of the piston cylinder 3 208 to first contract and draw the lubricating oil in the lubricating liquid tank 210 into the piston cylinder 3 208, and then activates the electric push rod 209 to extend and draw the lubricating oil from the forward part through the liquid pipe 305 connected to the connecting pipe 213. The drain hole 304 on the outer wall of 302 is used to discharge the liquid to lubricate the urethra, and the medical staff continuously pushes the forward part 302 through the hose 312 to insert the inserter 3 into the urethra. During the insertion process, the endoscope lens 306 at the left end of the forward part 302 transmits the image data information of the urethral opening to the forward part 302 through the data line 307, and converts the signal of the forward part 302 into a video signal and plays it on the display 203 to provide video guidance for urethral dilation surgery. When the forward part 302 moves to the position of the urethra that needs to be dilated, the electric motor on the right side of the piston cylinder 207 is activated. The push rod 209 is extended to form a positive pressure environment in the inner cavity of the piston cylinder 207, so that the air bag 309 is inflated through the trachea 311 connected to the connecting tube 213, thereby driving the surrounding expansion plates 310 to open outward to expand the urethra at that location. After the expansion is completed, the electric push rod 209 on the right side of the piston cylinder 207 is activated to contract, causing the air bag 309 to contract and retract the expansion plate 310 to prepare for the expansion of the next urethral lesion. Since this design is a dilation surgery performed by observing the real-time picture inside the urethra, it can increase the accuracy and effectiveness of surgical treatment.

[0030] The implementation principle of the embodiment of the urethral endoscope device and urethral dilation device of the present application is as follows:

[0031] When using the device, first insert the hexagonal wrench into the hexagonal slot 16, and then rotate the hexagonal wrench to drive the screw 15 to rotate. At this time, since the external threads on both sides of the outer wall of the screw 15 are arranged in opposite directions, the screw 15 will drive the two sliders 12 to move toward each other when it rotates. When the two sliders 12 move toward each other, the two cones 14 will be driven to fit together through the connecting rod 13. Then, lubricant is applied to the outer walls of the two cones 14, and the small-diameter ends of the two cones 14 are inserted into the patient's pudendal urethral opening with the help of auxiliary medical tools. After insertion, the screw 15 is driven to rotate in the opposite direction by rotating the hexagonal wrench to make the two cones 14 move away from each other to open the urethral opening, in preparation for the subsequent insertion, peeping and expansion of the inserter 3.

[0032] Of course, the controller 2 needs to be explained here. By setting up the controller 2 and starting the three electric push rods 209 to extend and contract respectively, the push-pull rods will drive the pistons in the piston cylinder 1 206, the piston cylinder 2 207 and the piston cylinder 3 208 to move left and right, thereby creating positive and negative pressure states in the inner cavities of the piston cylinder 1 206, the piston cylinder 207 and the piston cylinder 3 208. Based on this, after the lubricant is filled in the lubricating liquid tank 210, under the one-way check action of the one-way valve 1 211 and the one-way valve 2 212, when the piston cylinder 3 208 is under negative pressure, the lubricant in the lubricating liquid tank 210 will be drawn into the piston cylinder 3 208 through the pipeline. When the piston cylinder 3 208 is under positive pressure, the lubricant just drawn in will be discharged through the connecting pipe 213.

[0033] Combined with the functions of the expander 1 and the controller 2 described in the previous paragraph, when the expander 1 expands the patient's pudendal urethra, the medical staff first connects the liquid tube 305 to the connecting tube 213 at the left end of the piston cylinder 3 208, and then connects the data line 307 to the data interface 204 on the side of the signal converter 202, and then respectively connects the air tube 311 and the hose 312 to the connecting tube 213 at the left end of the piston cylinder 1 206 and the piston cylinder 2 207. After this step is completed, the electric push rod 209 on the right side of the piston cylinder 1 206 is first started to extend. At this time, the piston cylinder 1 206 inflates the rubber tube 312, so that the rubber tube 312 becomes straight and hard in conjunction with the hard sleeve 313 fixed on its outer periphery. Then the medical staff holds the rubber tube 312 and inserts the forward part 302 on the left side of the plug 301 into the patient's urethra opened by the cone 14. During the insertion process, the medical staff activates the electric push rod 209 on the right side of the piston cylinder 3 208 to first contract and draw the lubricating oil in the lubricating liquid tank 210 into the piston cylinder 3 208, and then activates the electric push rod 209 to extend and the lubricating oil is discharged from the liquid pipe 305 connected to the connecting pipe 213 from the bleed hole 3 on the outer wall of the forward part 302. 04 is discharged to lubricate the urethra, and the medical staff continuously pushes the forward part 302 through the hose 312 to insert the inserter 3 into the urethra. During the insertion process, the endoscope lens 306 at the left end of the forward part 302 transmits the image data information of the urethral opening to the forward part 302 through the data line 307, and the signal from the forward part 302 is converted into a video signal and played on the display 203 to provide video guidance for urethral dilation surgery. When the forward part 302 moves to the urethra position that needs to be dilated, the electric push rod 20 on the right side of the piston cylinder 207 is activated. 9 is extended to form a positive pressure environment in the inner cavity of the piston cylinder 207, so that the air bag 309 is inflated through the trachea 311 connected to the connecting tube 213, thereby driving the surrounding expansion plates 310 to open outward to expand the urethra at that location. After the expansion is completed, the electric push rod 209 on the right side of the piston cylinder 207 is started to contract, so that the air bag 309 contracts and retracts the expansion plate 310 to prepare for the expansion of the next urethral lesion. Since this design is a dilation surgery performed by observing the real-time picture inside the urethra, it can increase the accuracy and effectiveness of surgical treatment.
