Description

Technical Field

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

[0002] Urethral stricture is a urinary system disease, which is mainly manifested by the narrowing of the urethral lumen, affecting the discharge of urine. There are many causes of the disease, and the general causes are as follows. First of all, traumatic factors, such as straddle injuries, pelvic fractures, etc., which damage the urethra, are common causes of urethral stricture. Alternatively, iatrogenic factors, such as transurethral surgical operations (such as transurethral resection of the prostate, etc.), intraurethral instrument examinations, etc., may cause urethral stricture, etc.

[0003] Urethral dilation is one of the treatment methods for patients with urethral stricture. Currently, urologists mainly rely on experience and techniques to dilate the urethra using urethral probes. This type of urethral dilation without direct vision has certain risks and hidden dangers, such as false passage formation and urinary fistula. Therefore, it is necessary to invent a urethral endoscope device and a urethral dilation device, so that the urethral dilation operation can be completed under the guidance of a specialist, thereby reducing medical risks and making urethral dilation safer and more reliable.

[0007] In a preferred embodiment of the invention, both sides of the top of the rail plate are provided with sliding grooves adapted to the sliders, and the two sliders are slidably installed in the sliding grooves on both sides respectively.

[0008] In a preferred embodiment of the invention, a screw rod with opposite external threads on both sides of the outer wall is rotatably installed inside the rail plate, the screw rod is threadedly connected to two sliders, and a hexagonal groove is formed at the end of the screw rod located on the outer wall of the rail plate.

[0009] In a preferred embodiment of the invention, a display is disposed above the signal converter, and a data interface is disposed on a side wall of the signal converter.

[0010] In a preferred embodiment of the invention, electric push rods are fixedly installed on the upper right side of the three support plates, and the extended ends of the three electric push rods are fixedly connected to the pistons in piston cylinder one, piston cylinder two and piston cylinder three through push-pull rods respectively.

[0011] In a preferred embodiment of the invention, the medium allowed by the one-way valve 1 flows toward the piston cylinder 3, and the medium allowed by the one-way valve 2 flows away from the piston cylinder 3.

[0012] In a preferred embodiment of the invention, a circle of receding portion is provided on the right side of the plug, and both the forward portion and the receding portion are of arc-shaped design.

[0013] In a preferred embodiment of the invention, the outer circumference of the tail block is provided with receiving grooves adapted to the airbag and the expansion plate.

[0014] In a preferred embodiment of the invention, a rubber hose is fixedly connected to the right side of the tail block, and a plurality of hard sleeves which are linearly distributed and have gaps between them are fixedly sleeved on the outer periphery of the rubber hose.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] In the present invention, through the above design, when using the device, first insert the hexagonal wrench into the hexagonal slot, and then rotate the hexagonal wrench to drive the screw rod to rotate. At this time, since the external threads on both sides of the outer wall of the screw rod are arranged in opposite directions, the rotation of the screw rod will drive the two sliders to move toward each other. When the two sliders move toward each other, the two cones will be driven to fit each other 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 urethral opening with the help of auxiliary medical tools. After insertion, the screw rod is driven to rotate in the opposite direction by rotating the hexagonal wrench, so that the two cones are separated from each other to open the urethral opening, so as to prepare 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 respective extension and contraction will cause the pistons in piston cylinder one, piston cylinder two and piston cylinder three to move left and right through the push-pull rod, thereby creating positive and negative pressure states for the inner cavities of piston cylinder one, piston cylinder two and piston cylinder three. Based on this, after the lubricant is filled in the lubricating liquid tank, under the one-way check effect of the one-way valve one and the one-way valve two, when the piston cylinder three is under negative pressure, the lubricant in the lubricating liquid tank will be drawn into the piston cylinder three through the pipeline, and when the piston cylinder three is under positive pressure, the lubricant just drawn in will be discharged through the connecting tube. Combined with the functions of the expander and controller described in the previous paragraph, when the expander opens the patient's pudendal urethra opening, the medical staff first connects the liquid tube to the connecting tube at the left end of the piston cylinder three, and then connects the data cable to the data interface on the side of the signal converter. After the operation is completed, the electric push rod on the right side of piston cylinder one is started to extend. At this time, piston cylinder one inflates the hose, so that the hose and the hard sleeve fixed on its outer periphery become straight and hard. Then the medical staff holds the hose and inserts the forward part on the left side of the plug into the patient's urethra opened by the cone. During the insertion process, the medical staff starts the electric push rod on the right side of piston cylinder three to first contract and draw the lubricating oil in the lubricating liquid tank into piston cylinder three, and then starts the electric push rod to extend and discharge the lubricating oil from the leakage hole on the outer wall of the forward part through the liquid pipe connected with the connecting pipe to lubricate the urethra, and cooperates with the medical staff to continuously push the forward part through the hose to realize the insertion of the inserter 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 operation. 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, thereby driving the surrounding expansion plates to open outward to expand the urethra at that location. After the expansion is completed, the electric push rod on the right side of the piston cylinder 2 is started to contract, so that the airbag contracts and retracts the expansion plate to prepare for the expansion of the next urethral lesion. This design is due to the dilation operation performed by observing the real-time image inside the urethra.This can increase the accuracy and effectiveness of surgical treatment.

[0024] The following will be combined Figure 1-Figure 4 A urethral endoscope device and a urethral dilation device according to an embodiment of the present invention are described in detail.

[0025] Example:

The two sliders 12 are respectively slidably installed in the slide grooves on both sides, and the inside of the track plate 11 is rotatably installed with a screw rod 15 with external threads on both sides of the outer wall oppositely arranged, the screw rod 15 is threadedly connected with the two sliders 12, and the end of the screw rod 15 located on the outer wall of the track plate 11 is opened with a hexagonal groove 16, a connecting rod 13 is fixedly installed on the top of the slider 12, and a cone 14 is fixedly installed on the inner side of the top of the connecting rod 13.

[0027] By setting the expander 1, when using the device, first insert the hexagonal wrench into the hexagonal groove 16, and then rotate the hexagonal wrench to drive the screw rod 15 to rotate. At this time, since the external threads on both sides of the outer wall of the screw rod 15 are arranged oppositely, the screw rod 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 each other 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 auxiliary medical tools. After insertion, the screw rod 15 is driven to rotate in the opposite direction by rotating the hexagonal wrench, so that the two cones 14 are separated from each other to open the urethral opening, so as to prepare for the subsequent insertion, peeping and expansion of the inserter 3.

[0028] 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 arranged above the signal converter 202, and a data interface 204 is arranged on the side wall of the signal converter 202. Three support plates 205 are fixedly installed on the top left side of the support platform 201, and piston cylinder 1 206, piston cylinder 2 207 and piston cylinder 3 208 are fixedly installed on the top of the three support plates 205, and electric push rods 209 are fixedly installed on the top right side of the three support plates 205. The extended ends of the three electric push rods 209 are connected to the piston cylinder 1 206 and the piston cylinder 2 through push-pull rods. 207 and the piston in the piston cylinder three 208 are fixedly connected, a lubricating liquid tank 210 is fixedly installed on the top of the piston cylinder three 208, and the left end of the piston cylinder three 208 is fixedly connected with a one-way valve one 211 and a one-way valve two 212 respectively. 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, the left end of the one-way valve two 212 is fixedly connected with a connecting pipe 213, and the left ends of the piston cylinder one 206 and the piston cylinder two 207 are also fixedly connected with a connecting pipe 213.

[0029] By setting up the controller 2, starting the three electric push rods 209 to extend and contract respectively will drive the pistons in the piston cylinder 1 206, the piston cylinder 207 and the piston cylinder 3 208 to move left and right through the push-pull rods, thereby creating positive and negative pressure states for 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 effect of the one-way valve 1 211 and the one-way valve 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, and when the piston cylinder 3 208 is under positive pressure, the lubricant just drawn in will be discharged through the connecting pipe 213.

[0030] 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 is 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 lens 306 is fixedly installed at the center of the left side of the forward portion 302. The right side of the tail block 308 is fixedly connected to A data line 307 electrically connected to the endoscope lens 306 is connected, airbags 309 are fixedly installed on the outer four sides of the tail block 308, an expansion plate 310 is fixedly installed on the outer end of the airbag 309, and a receiving groove compatible with the airbag 309 and the expansion plate 310 is opened on the outer four sides 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 which are linearly distributed and have gaps between them.

[0031] 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 expands the patient's pudendal urethra opening, the medical staff first connects the liquid tube 305 with 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 rubber 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 The push rod 209 is extended, and at this time, the piston cylinder 1 206 inflates the rubber tube 312, so that the rubber tube 312 and the hard sleeve 313 fixed on the outer periphery thereof become straight and hard, and then the medical staff holds the rubber tube 312 to insert the forward part 302 on the left side of the plug 301 through the urethra opening of the patient 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 with the connecting pipe 213. The discharge 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 rubber tube 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 in real time through the data line 307, and converts the signal of the forward part 302 into a video signal to be played on the display 203 to provide video image guidance for the urethral dilation surgery. When the forward part 302 moves to the urethra position 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 airbag 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. When 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 airbag 309 contracts and retracts the expansion plate 310 to prepare for the expansion of the next urethral lesion. This design is a dilation surgery performed by observing the real-time picture inside the urethra, which can increase the accuracy and effectiveness of surgical treatment.

[0032] The implementation principle of the urethral endoscope device and the urethral dilation device of the present application is as follows:

[0033] When using the device, first insert the hexagonal wrench into the hexagonal groove 16, and then rotate the hexagonal wrench to drive the screw rod 15 to rotate. At this time, since the external threads on both sides of the outer wall of the screw rod 15 are arranged in opposite directions, the rotation of the screw rod 15 will drive the two sliders 12 to move toward each other. When the two sliders 12 move toward each other, the two cones 14 will be driven to fit each other 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 rod 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, so as to prepare for the subsequent insertion, peeping and expansion of the inserter 3.

[0034] Of course, the controller 2 needs to be explained here. By setting 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 207 and the piston cylinder 3 208 to move left and right, thereby creating positive and negative pressure states for 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 effect of the one-way valve 1 211 and the one-way valve 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, and when the piston cylinder 3 208 is under positive pressure, the lubricant just drawn in will be discharged through the connecting pipe 213.

[0035] 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 urethral opening, 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 connects the air tube 311 and the rubber hose 312 to the connecting tube 213 at the left end of the piston cylinder 1 206 and the piston cylinder 2 207 respectively. 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 coordination with the hard sleeve 313 fixedly sleeved 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 urethra opening of the patient stretched open 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 draw the lubricating oil through the liquid pipe 305 connected with the connecting pipe 213 from the leakage hole on the outer wall of the forward part 302. 304 is discharged to lubricate the urethra, and the medical staff continuously pushes the forward part 302 through the rubber tube 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 in real time 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 image guidance for the 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 started. 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. This design is a dilation surgery performed by observing the real-time picture inside the urethra, which can increase the accuracy and effectiveness of surgical treatment.
