Description

Technical Field

[0001] The present invention relates to the technical field of urological surgical treatment, and in particular to a ureteroscope irrigation pressure pulse regulating device for urological surgery. Background Art

[0002] A urological ureteroscope is a minimally invasive endoscopic device used to diagnose and treat urinary tract diseases. It primarily enters the patient's urinary tract through a natural orifice for examination and surgical procedures. This technology is widely used in the diagnosis and treatment of urinary tract diseases, such as ureteral stone removal, tumor biopsy, and stricture dilation. Modern ureteroscopic surgery requires equipment with both precise mechanical performance and reliable irrigation and flushing capabilities to ensure a clear surgical field of view and maintain stable intra-urinary tract pressure. This places high demands on the ureteroscope's structural design and functional integration.

[0003] The ureteroscopic irrigation system in the existing technology generally has the problem of inaccurate pressure regulation. Traditional devices lack an intelligent pulse control module and cannot adjust the irrigation pressure and pulse mode in real time according to surgical needs. Especially when backwashing is required, existing equipment often requires the replacement of connecting pipes or external drainage devices, which is not only cumbersome to operate, but also prone to surgical interruption and contamination risks. The limitations of this pressure regulation method directly affect the efficiency of the operation, and it is difficult to meet the precise control requirements of the irrigation system for complex urological surgery. Therefore, a urological ureteroscopic irrigation pressure pulse regulation device is provided to solve the above-mentioned problems. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a urology ureteroscope irrigation pressure pulse regulating device to solve the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0013] Furthermore, the filter tube is provided with two discharge ports, and the interior of the filter tube is filled with a plurality of filter elements.

[0014] Furthermore, a guide plate is inserted into the filter tube, and the guide plate separates the one filter element on the left and the two filter elements on the right, and the guide plate is located between the two discharge ports.

[0015] Furthermore, the tube mirror end includes a tube mirror connecting rod, which is connected to the inner connecting rod. The end of the tube mirror connecting rod away from the inner connecting rod is hinged with a liquid spraying end and a first positioning plate.

[0017] Furthermore, the angle between the two first positioning plates is an acute angle, and filter screens are installed on the multiple liquid spraying ends.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This urology ureteroscope irrigation pressure pulse regulator achieves the dual functions of precise operation and pressure regulation through innovative structural design.

Through the cooperation of a micro-liquid pump and a multi-way valve, different numbers of first connecting tubes can be selected for connection, thereby precisely adjusting the pulse intensity and position. The innovative guide plate design allows the liquid direction to be selected as needed, while the multi-layer filter element ensures that the liquid entering the body is clean and safe. The system supports bidirectional pulse mode: the forward pulse can inject the filtered liquid (including optional saline) through the spray end; the reverse pulse can lead the liquid out through the discharge port to the drainage device or other liquid storage bottle. This intelligent pressure regulation system provides a safer and more accurate perfusion solution for urological surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Reference Figure 1-6 A urology ureteroscope irrigation pressure pulse regulating device includes a ureteroscope body 1, a support frame 5 is installed on the ureteroscope body 1, a tube mirror end 3 is installed at the front end of the ureteroscope body 1, the ureteroscope body 1 is installed with the support frame 5, the support frame 5 is installed with a liquid pulse end 4, and the pressure pulse output end of the liquid pulse end 4 is connected to the tube mirror end 3;

[0031] A support tube 6 is connected and installed between the support frame 5 and the tube mirror end 3 .

[0032] As an optimization solution, Figure 1-6 As shown, the ureteroscope body 1 includes a first gripping end 11, the first gripping end 11 is hingedly connected to a second gripping end 13, the first gripping end 11 is rotatably connected to an outer connecting rod 14, an inner connecting rod 15 is slidably connected inside the outer connecting rod 14, one end of the inner connecting rod 15 is connected to the second gripping end 13, and the other end of the inner connecting rod 15 is connected to the second gripping end 13;

[0033] A spring sheet 12 is connected between the first gripping end 11 and the second gripping end 13 . The spring sheet 12 forces the first gripping end 11 and the second gripping end 13 to form a 60-degree angle. An auxiliary handle is installed on the side of the second gripping end 13 .

[0034] Specifically, when the ureteroscope body 1 is in use, when it is necessary to pull the inner connecting rod 15 to drive the end of the tube 3 to work, it is only necessary to hold the first gripping end 11 and the second gripping end 13 and then clamp and bend the spring sheet 12. That is, at this time, when the first gripping end 11 and the outer connecting rod 14 are in stationary position, the second gripping end 13 will drive the inner connecting rod 15 to move backward, thereby tightening the entire end of the tube 3. At this time, the end of the tube 3 is closed and can start working, and the overall adjustment can be achieved by holding and rotating the second gripping end 13.

[0035] As an optimization solution, Figure 1-6 As shown, multiple patient body fixation components 2 are inserted into the support tube 6, and the patient body fixation components 2 include a connecting ring 21. Multiple elastic fixing belts 22 are installed on the side of the connecting ring 21. Velcro 23 is sewn on the multiple elastic fixing belts 22, and the elastic fixing belts 22 are supported by medical elastic materials.

[0036] Specifically, when or before work, the ureteroscope body 1 and the end of the ureteroscope 3 can move the connecting ring 21 to the required position on the support tube 6, and then use the elastic fixing belt 22 and Velcro 23 on the connecting ring 21 to connect and bind with the patient or other brackets to reduce the pressure on the doctor's arm.

[0037] As an optimization solution, Figure 1-6 As shown, the liquid pulse end 4 includes a micro liquid pump 43 and a filter tube 44. One end of the micro liquid pump 43 is connected to the filter tube 44, and the other end of the micro liquid pump 43 is connected to the multi-way valve 42. The multi-way valve 42 is connected to multiple first connecting tubes 41, and the other ends of the multiple first connecting tubes 41 are all connected to the tube mirror end 3. Two discharge ports 47 are provided on the filter tube 44. The interior of the filter tube 44 is filled with multiple filter cartridges 46. A guide plate 45 is inserted into the filter tube 44. The guide plate 45 separates a filter cartridge 46 on the left and two filter cartridges 46 on the right, and the guide plate 45 is located between the two discharge ports 47.

[0038] Specifically, when liquid pulses need to be realized, the micro liquid pump 43 can be turned on, and the liquid entry pulse or liquid discharge pulse can be selected according to the actual situation. When the entry pulse is selected, whether to open the guide plate 45 can be selected according to the surrounding environment, and then the discharge port 47 can be directly connected to the physiological saline. Then the liquid is filtered through multiple filter elements 46 and enters the micro liquid pump 43 to the multi-way valve 42. In the multi-way valve 42, the inner ring can be rotated as needed to select the corresponding number of first connecting tubes 41 to be connected to the micro liquid pump 43. The intensity of the pulse and the position of the corresponding pulse can be adjusted. Then the liquid passes through the first connecting tube 41 and the inner connecting rod 15, and is discharged through the liquid spray end 35 to realize the pulse. At this time, the overall operation is completed. If the discharge pulse needs to be reversed, the discharge port 47 needs to be connected to the corresponding drainage tube or drainage bag.

[0039] As an optimization solution, Figure 1-6 As shown, the tube mirror end 3 includes a tube mirror connecting rod 34, which is connected to the inner connecting rod 15, and the end of the tube mirror connecting rod 34 away from the inner connecting rod 15 is hinged with a spray end 35 and a first positioning plate 31, and the hinged end of the first positioning plate 31, the spray end 35 and the tube mirror connecting rod 34 is slidably connected to the inner wall of the support tube 6, and an auxiliary lighting lamp 33 and two miniature cameras 32 for assisting the auxiliary lighting lamp 33 are installed on the first positioning plate 31. A plurality of drainage holes are provided on the spray end 35, and the end of the first connecting pipe 41 away from the multi-way valve 42 is connected to the plurality of drainage holes on the spray end 35. The angle between the two first positioning plates 31 is an acute angle, and a filter screen is installed on each of the plurality of spray ends 35.

[0040] Specifically, when the end of the tube mirror 3 is working, after it is inserted into the patient's urinary tract, the first positioning plate 31 and the spray end 35 are slightly unfolded. At this time, the situation inside the urinary tract can be observed through the micro camera 32, and the addition of two auxiliary lights 33 can assist the micro camera 32 in observing more clearly.

[0041] Working principle: The device is externally supported by a support frame 5, a ureteroscope body 1, a support tube 6, and a tube end 3. Internally, the ureteroscope body 1 controls the tube end 3, while the liquid pulse end 4 cooperates to achieve stable pulse regulation.

[0042] When the ureteroscope body 1 is in use, when it is necessary to pull the inner connecting rod 15 to drive the end of the tube 3 to work, it is only necessary to hold the first gripping end 11 and the second gripping end 13 and then clamp and bend the spring piece 12. That is, at this time, when the first gripping end 11 and the outer connecting rod 14 are in fixed position, the second gripping end 13 will drive the inner connecting rod 15 to move backward, thereby tightening the entire end of the tube 3. At this time, the end of the tube 3 is closed and can start working. The overall adjustment can be achieved by holding and rotating the second gripping end 13.

[0043] During or before operation, the ureteroscope body 1 and the end 3 of the ureteroscope can be moved to the desired position on the support tube 6, and then the elastic fixing belt 22 and the Velcro 23 on the connecting ring 21 can be used to connect and bind the ureteroscope to the patient or other supports, thereby reducing the pressure on the doctor's arm.

[0044] When the end of the tube mirror 3 is working, after it is inserted into the patient's urinary tract, the first positioning plate 31 and the liquid spraying end 35 are slightly unfolded, and the micro camera 32 can observe the situation in the urinary tract. In addition, two auxiliary lights 33 can be added to assist the micro camera 32 in observing more clearly.

[0045] When liquid pulse is needed, the micro liquid pump 43 can be turned on, and the liquid entry pulse or liquid discharge pulse can be selected according to the actual situation. When the entry pulse is selected, whether to open the guide plate 45 can be selected according to the surrounding environment, and then the discharge port 47 can be directly connected to the physiological saline. Then the liquid is filtered through multiple filter elements 46 and enters the micro liquid pump 43 to the multi-way valve 42. In the multi-way valve 42, the inner ring can be rotated as needed to select the corresponding number of first connecting tubes 41 to be connected to the micro liquid pump 43. The intensity of the pulse and the position of the corresponding pulse can be adjusted. Then the liquid passes through the first connecting tube 41 and the inner connecting rod 15, and is discharged through the liquid spray end 35 to realize the pulse. At this time, the overall operation is completed. If the discharge pulse needs to be reversed, the discharge port 47 needs to be connected to the corresponding drainage tube or drainage bag.

[0046] The actual operation steps of the device:

[0047] S1. First, connect the ureteroscope body 1 to the support tube 6 via the support frame 5 to form a complete operating unit. Before operation, slide the connecting ring 21 along the support tube 6 to the appropriate position. Secure the device to the patient's body or an external support using the elastic fixing band 22 and Velcro 23 to reduce the burden on the physician during operation. Ensure that the end of the ureteroscope 3 is in the initial extended position, and the first positioning plate 31 and the spray end 35 are at the appropriate extended angle to prepare for subsequent operation.

[0048] During operation, the doctor holds the first gripping end 11 steady with one hand and applies pressure with the second gripping end 13 with the other hand, bending and deforming the spring leaf 12. The inner connecting rod 15, guided by the outer connecting rod 14, then moves backward, driving the end of the tube end 3 to complete the closing motion. The interior of the urinary tract is observed using a micro-camera 32 and auxiliary lighting 33. The rotation angle of the second gripping end 13 can be adjusted as needed, enabling precise manipulation of the end of the tube end 3. During operation, the extension of the first positioning plate 31 can be adjusted at any time to provide a better field of view.

[0049] S3. After starting the microfluidic pump 43, the liquid direction is selected according to surgical requirements. When a forward pulse is required, the multi-way valve 42 selects a corresponding number of first connecting tubes 41 to connect to the microfluidic pump 43. The angle of the guide plate 45 is adjusted to control the liquid direction. After being purified by the filter element 46, the liquid is discharged from the liquid spray end 35 through the first connecting tubes 41 and the internal connecting rod 15. The pulse intensity can be precisely controlled by adjusting the number of connected first connecting tubes 41, achieving different intensities of perfusion.

[0050] S4. When reverse pulse operation is required, connect outlet 47 to the drainage device. Keep microfluidic pump 43 running and adjust multi-way valve 42 to reverse the flow of fluid, effectively draining the fluid from the surgical area. After the operation is complete, first turn off microfluidic pump 43, then release second grip 13 to return end 3 of the tubescope to its initial position. Finally, release connecting ring 21 and remove the device from the patient, completing the entire operation.
