Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and in particular to a visualized urethral probe. Background Technology

[0002] In urological clinical treatment, ureteral stents are commonly used medical devices to establish an artificial passage from the kidney to the bladder to relieve symptoms such as hydronephrosis and renal colic caused by ureteral obstruction. However, after catheter removal, ureteral stents are prone to dislodge into the urethra, causing discomfort such as urinary incontinence. Therefore, it is necessary to reinsert the dislodged ureteral stent into its original position.

[0003] Currently, in clinical practice, catheters and other instruments are typically used to push back indwelling ureteral stents. However, existing techniques have the following shortcomings: First, traditional catheters do not provide visualization, preventing doctors from directly observing the internal urethra during the procedure. Doctors rely on touch and experience, which can easily lead to failure, especially in complex cases such as urethral strictures or stones, resulting in a low success rate. Second, current pushing methods are mostly contact-based. Because the contact surface between the catheter and the ureteral stent is smooth, slippage is common, making stable and accurate pushing difficult and affecting operational efficiency and safety.

[0004] Therefore, in order to address the above problems, this invention proposes a visualized urethral probe. Summary of the Invention

[0005] The present invention aims to provide a visualized urethral probe to solve the problem that the existing technology cannot observe the internal condition of the urethra in real time when returning an indwelling ureteral stent, resulting in a low success rate of operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A visual urethral probe includes: an operating part for operation control, and a head housing with a camera mounted thereon, the head housing and the operating part being connected by a connecting tube; the operating part is used to control and power the internal electrical components of the device.

[0008] The head shell includes an inner shell and an outer shell. A clamping and pushing module is housed within the outer shell. The clamping and pushing module includes a central slide rod and a clamping plate. A pushing control ring and a rotation control ring are slidably connected to the central slide rod. The pushing control ring is connected to a first pushing rack, which meshes with a linkage gear. The linkage gear meshes with a second pushing rack, which is connected to a sliding block that is rotatably connected to the clamping plate. Pulling the pushing control ring controls the horizontal movement of the clamping plate. The rotation control ring is connected to the clamping plate via a pull rope, and pulling the rotation control ring controls the rotation of the clamping plate.

[0009] The inner housing contains a camera and a cleaning module. A light source is located on the side of the camera. The cleaning module is used to clean the camera and includes a rinsing module and a wiping module. The rinsing module is used to rinse the camera, and the wiping module is used to wipe the camera back and forth.

[0010] Furthermore, the propulsion control ring and the rotation control ring are connected to the inner housing and the outer housing respectively via springs. A torsion spring is sleeved on the rotating shaft of the clamping plate. The propulsion control is connected to the main control line. After passing through the rotation control ring, the main control line goes through the connecting pipe to the inside of the operating part. The operating part is connected to the clamping motor. The clamping motor is coaxially connected to the winding wheel. The main control line is wound around the winding wheel.

[0011] Furthermore, the first propulsion rack, the linkage gear, the second propulsion rack, the sliding block, and the clamping plate are all configured as four and arranged in a circular array along the propulsion control ring. The pull ropes are configured as four and arranged in a circular array along the rotation control ring.

[0012] Furthermore, a sliding groove is provided inside the outer casing, and both the sliding block and the clamping plate are located inside the sliding groove, allowing the sliding block to slide along the sliding groove.

[0013] Furthermore, the pull rope is provided with a spiral section, the length of which is equal to the distance between the propulsion control ring and the rotation control ring.

[0014] Furthermore, the front end of the clamping plate is connected to an elastic cover.

[0015] Furthermore, the rinsing module includes a rinsing block connected to the inner housing. The rinsing block is connected to several rinsing nozzles facing the camera. The rinsing block is connected to an infusion tube, which passes through the inner and outer housings and then through a connecting tube to the operating section. A storage box is connected to the side of the operating section. The storage box is used to store rinsing liquid, and a suction pump is installed inside the storage box, which is connected to the infusion tube.

[0016] Furthermore, the wiping module includes a miniature reciprocating motor, a central gear coaxially connected to the miniature reciprocating motor, wiping racks meshing on both sides of the central gear, wiping strips connected to the wiping racks, and through slots provided on both sides of the camera, along which the wiping strips slide.

[0017] Furthermore, a guide wire tube is provided through the outer shell, with the front end of the guide wire tube located in the head shell and the tail end of the guide wire tube passing through the operating part. The guide wire tube is used to provide a channel for the guide wire. An expansion ring is detachably connected to the outside of the outer shell, and multiple expansion rings with different diameters are provided.

[0018] Furthermore, the operating unit is equipped with a battery module, which powers the internal electric components of the device. The operating unit is rotatably connected to a control display screen, which controls the camera and light source. The operating unit is equipped with several buttons for controlling the suction pump, the micro reciprocating motor, and the clamping motor.

[0019] The principle and beneficial effects of this technical solution:

[0020] (1) The device of the present invention has a built-in miniature camera and light source in the head shell, which is electrically connected to the control display screen of the operating part through the connecting tube. During the operation, the doctor can observe the image inside the urethra in real time and in high definition, actively identify obstacles such as urethral stricture, stones, and mucosal folds, and realize precise operation under visual guidance. This avoids the blindness caused by relying entirely on feel and experience when pushing in the traditional way, and significantly reduces the operation error rate.

[0021] (2) The device of the present invention integrates a rinsing module and a wiping module on the side of the camera. The rinsing module uses a suction pump to deliver rinsing fluid from the reservoir to the rinsing nozzle for directional rinsing of the camera surface. The wiping module uses a micro reciprocating motor to drive the wiping strip to move back and forth, mechanically wiping the camera lens. The two work together to form a self-cleaning mechanism that combines rinsing and wiping, ensuring that the camera maintains a clear field of vision even in complex physiological environments such as blood and mucus. The self-cleaning mechanism ensures the continuity of images throughout the insertion, advancement, and repositioning process, and doctors do not need to interrupt the operation for cleaning, improving the smoothness of the operation. In some cases with more bleeding and abundant secretions, the cleaning module can quickly restore the field of vision and has good environmental adaptability.

[0022] (3) The device of the present invention is equipped with a clamping and pushing module. Pulling the main control line backward drives the pushing control ring to move backward, and then drives the sliding block to move forward through the gear and rack transmission mechanism composed of the first pushing rack, the linkage gear, and the second pushing rack, so that the clamping plate extends out of the outer shell. Pulling the pushing control ring further causes it to contact the rotation control ring, which drives the rotation control ring to move backward. Multiple traction ropes arranged in a circular array simultaneously pull multiple clamping plates to rotate inward, so as to achieve concentric and stable clamping of the indwelling ureteral stent. By setting up the clamping and pushing module, the problem of slippage caused by the smooth contact surface in the traditional pushing method can be effectively avoided, and the ureteral stent can be prevented from tilting, twisting or falling off during the pushing process. It can achieve one-time clamping and accurate reset, and reduce repeated operations.

[0023] (4) In the device of the present invention, expansion rings of different diameters can be detachably connected to the outer side of the outer shell. By connecting the expansion rings, the diameter of the outer shell can be increased, thereby expanding the patient's urethra as needed. The device of the present invention is also provided with a guide wire tube, which is used to provide a channel for the guide wire. With the assistance of the guide wire, the connecting tube can pass through the urethra more safely. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0035] like Figures 1-8The illustrated visualization urethral probe includes an operating part 4 for external control and a head housing 1 at the front end for observation, clamping and propulsion. The head housing 1 and the operating part 4 are connected by a hollow connecting tube 5.

[0036] The head housing 1 includes an inner housing 2 and an outer housing 3. The inner housing 2 is embedded inside the outer housing 3. The front end of the inner housing 2 is horizontally flush with the front end of the outer housing 3. A camera 21 is fixedly connected to the front end of the inner housing 2. A glass protective plate 22 is fixedly connected to the front end of the camera 21. A light source 23 is provided on the side of the camera 21. The camera 21 and the light source 23 are connected to the control display screen 41 on the operation unit 4 via wired or wireless means. The wired means are routed through the connecting pipe 5. The control display screen 41 can display the shooting image of the camera 21. At the same time, the control display screen 41 can also adjust and control the parameters of the camera 21 such as focal length, exposure, and contrast. The control display screen 41 can also control and adjust the brightness of the light source 23.

[0037] The inner shell 2 is also equipped with a cleaning module. The cleaning module is to ensure that the camera 21 can capture clear images and to prevent tissue debris, urethral mucus, etc. from obstructing the camera 21 and causing the images captured by the camera 21 to be unclear. The cleaning module includes a rinsing module and a wiping module. The rinsing module includes a rinsing block 24 fixedly connected to the side of the camera 21. The rinsing block 24 is provided with several rinsing nozzles 241 facing the camera 21. The rinsing block 24 is connected to an infusion tube 25. The infusion tube 25 passes through the inner shell 2 and the outer shell 3 and is connected to the inside of the storage box 42 via a connecting tube 5. The storage box 42 is connected to the side of the operation unit 4. The storage box 42 is used to store rinsing liquid, such as saline. The storage box 42 is provided with a suction pump 43. The suction pump 43 is connected to the infusion tube 25. The suction pump 43 is used to pump the rinsing liquid in the storage box 42 into the infusion tube 25, and finally spray it out from the rinsing nozzles 241 to rinse the surface of the camera 21. The button for controlling the suction pump 43 is located at the bottom of the handle 46. The wiping module includes a miniature reciprocating motor 26, which is fixedly connected inside the inner housing 2. A central gear 27 is coaxially connected to the miniature reciprocating motor 26, and wiping racks 271 mesh with the upper and lower sides of the central gear 27. The wiping racks 271 are fixedly connected to wiping strips 272. Through grooves 28 are provided on both sides of the camera 21, allowing the wiping strips 272 to slide along the through grooves 28. Control buttons for controlling the miniature reciprocating motor 26 are located on the top of the operating unit 4 and the side of the handle 46. With this structure, when the camera 21 is adhered to by tissue debris or urethral mucus inside the urethra, a suction pump 43 can draw flushing liquid, which is then sprayed from the flushing nozzle 241 through the infusion tube 25 to flush the surface of the camera 21. After flushing, the miniature reciprocating motor 26 can be activated to drive the wiping strips 272 to move back and forth, thus wiping the camera 21 repeatedly, further improving cleaning ability and effectively ensuring the visibility and clarity of the camera 21.

[0038] By using the front-end camera 21 and the cleaning module, the risk of injury can be significantly reduced. Traditional urethral catheter insertion relies mainly on the doctor's feel and experience. In cases of urethral stricture, stones, etc., it is easy to cause urethral mucosal abrasion and tearing. With the camera 21, the doctor can actively avoid injury, making the operation safer. The cleaning module of the camera 21 is to ensure that the camera 21 can always maintain a clear image during the insertion process, avoiding the trouble of removing and cleaning the camera 21, and ensuring that the insertion process can be carried out quickly and efficiently.

[0039] The surgical housing 3 has L-shaped slots 39 on both sides of its exterior. The slots 39 are designed to work with the locking blocks 71 on the dilation ring 7 for detachable connection. If urethral dilation is required, the locking blocks 71 on the dilation ring 7 can be inserted along the slots 39, and then the dilation ring 7 can be rotated to connect to the outside of the housing 3, thereby increasing the diameter of the housing 3. The dilation ring 7 can be set with multiple different diameters, so that it can be replaced according to different dilation needs.

[0040] The outer shell 3 is also equipped with a guide wire tube 6. The front end of the guide wire tube 6 is located at the head shell 1, while the tail end is equipped with an operating part 4. The guide wire can be inserted into the front end through the guide wire tube 6. With the assistance of the guide wire, the connecting tube can pass through the urethra more safely.

[0041] The outer shell 3 is equipped with a clamping and pushing module, which is used to clamp the indwelling ureter, allowing it to be quickly returned to its original position. The clamping and pushing module includes a central slide rod 31, which is fixedly connected between the inner shell 2 and the outer shell 3. A pushing control ring 32 and a rotation control ring 33 are slidably connected to the central slide rod 31. The pushing control ring 32 is connected to the bottom end of the inner shell 2 via a spring, and the rotation control ring 33 is connected to the outer shell 3 via a spring. Both springs are sleeved on the central slide rod 31. The pushing control ring 32 is connected to... Four first propulsion racks 321 are connected, each with an L-shaped structure. These four racks are arranged in a circumferential array along the propulsion control ring 32. Four linkage gears 322 are rotatably connected to the bottom of the inner housing 2. Each linkage gear 322 meshes with one of the four first propulsion racks 321. One side of each linkage gear 322 meshes with a first propulsion rack 321, and the other side meshes with a second propulsion rack 323. There are four second propulsion racks 323. The first propulsion racks 321, linkage gears 322, and second propulsion racks 323 are all configured... Four slide blocks 34 are arranged in a circular array along the propulsion control ring 32. The second propulsion rack 323 is connected to a sliding block 34. The interior of the outer shell 3 is provided with a sliding groove 35 for the sliding block 34 to slide. The sliding block 34 can slide horizontally along the sliding groove 35. A clamping plate 36 is rotatably connected to the front end of the sliding block 34. A torsion spring is provided on the rotating shaft of the clamping plate 36. An elastic covering 361 is embedded in the front end of the clamping plate 36. The elastic covering 361 is provided to avoid damage to the indwelling ureter caused by excessive clamping force, and to reduce the impact on the body interior when the clamping plate 36 extends to the outside. Risk of damage; The rotary control ring 33 is connected to four pull ropes 37. The four pull ropes 37 pass through the sliding block 34 and are fixedly connected to the clamping plate 36. The pull ropes 37 are also provided with a spiral section. The length of the spiral section is equal to the distance between the propulsion control ring 32 and the rotary control ring 33. This spiral section is to prevent the rotary control ring 33 from moving forward when the sliding block 34 moves forward. The length of the spiral section is equal to the maximum distance that the sliding block 34 can move forward. That is, the clamping plate 36 can only rotate and clamp after the sliding block 34 has moved forward to the maximum distance.A main control line 38 is connected to the end of the push control ring 32. The main control line 38 passes through the rotation control ring 33 and the outer shell 3, and then through the connecting pipe 5 to the inside of the operation part 4. The inside of the operation part 4 is connected to a clamping motor 44. The clamping motor 44 is coaxially connected to a winding wheel 45. The main control line 38 is wound around the winding wheel 45. The button for adjusting and controlling the clamping motor 44 is located on the top of the handle 46. The clamping motor 44 can be controlled to rotate forward and backward by the button. Forward rotation can control the main control line 38 to pull the push control ring 32 backward. Reverse rotation causes the main control line 38 to wind back onto the winding wheel. During the winding process, due to the action of the spring and torsion spring, the clamping plate and the sliding block can return to their initial state.

[0042] With the aforementioned clamping and pushing module, the indwelling ureter can be clamped and pushed. When the device enters the bladder through the urethra and needs to clamp and push the indwelling ureter, the clamping motor 44 can be activated to rotate, causing the main control line 38 to pull the pushing control ring 32 backward. The backward movement of the pushing control ring 32 drives the sliding block 34 forward, thereby causing the clamping plate 36 to extend out of the outer shell 3 and rotate for clamping. Continuing to pull the pushing control ring 32 backward causes the pushing control ring 32 to contact the rotation control ring 33, which is then driven to move backward. The rotating control ring 33 moves backward and is pulled by the traction rope 37, causing the four clamping plates 36 to rotate inward, thereby clamping the indwelling ureter. The camera 21 can observe in real time whether it is clamped and the status during the clamping and advancement process. It should also be noted that when the device is advanced in the urethra, the clamping plates 36 are always inside the outer shell 3 and will not affect the advancement process. Their shape is no different from that of an ordinary urethral tube. The clamping plates 36 will only extend to clamp and reset the indwelling ureter when it is necessary to reset it.

[0043] In this invention, the operating part 4 is a cubic housing. A handle 46 is provided on the top of the operating part 4. Buttons for controlling the clamping motor 44 and the suction pump 43 are respectively provided on the top and bottom of the handle 46. Buttons for controlling the micro reciprocating motor 26 are provided on the top of the operating part 4 and the side of the handle 46. A control display screen 41 for controlling the camera 21 and the light source 23 is rotatably connected to the top of the operating part 4. A liquid storage box 42 is fixedly connected to the side of the operating part 4. The liquid storage box 42 is used to store rinsing liquid. The suction pump 43 is provided in the liquid storage box 42 and is connected to the infusion tube 25. A battery module 47 is also provided inside the operating part 4. The battery module 47 is used to power the electronic components in the device. The clamping motor 44 is connected inside the operating part 4. The clamping motor 44 is coaxially connected to the winding wheel 45. The main control line 38 is wound around the winding wheel 45.

[0044] The specific implementation process is as follows: When in use, hold the connecting tube 5 with one hand and push the head shell 1 into the urethra, while holding the handle 46 with the other hand and observing the situation inside the urethra in real time through the control display screen 41. The guide wire can be inserted through the guide wire tube 6 to assist in the advancement of the connecting tube. The camera 21 allows observation of the inside of the urethra, identifying conditions such as urethral stricture or stones. Real-time images from the camera 21 enable doctors to clearly observe the path and obstacles ahead of the tube, proactively avoiding damage and ensuring safer operation. When the cleaning module is in operation, a suction pump 43 is activated via a button to extract flushing liquid from the reservoir 42. Saline solution can be used for flushing. The flushing liquid travels through the infusion tube 25 to the flushing block 24 and is finally sprayed out from the flushing nozzle 241, cleaning the surface of the camera 21. Simultaneously, a miniature reciprocating motor 26 can be activated via a button to rotate back and forth. This motor drives the wiping rack 271 to move left and right, which in turn drives the wiping strip 272 to move back and forth, thus wiping the lens of the camera 21 repeatedly, further improving cleaning capabilities and ensuring the camera 21 remains clear in real time. When it is necessary to clamp the indwelling ureter, the clamping motor 44 is started to rotate forward by pressing the button. The rotating wheel 45 drives the main control line 38 to pull the push control ring 32 backward. The push control ring 32 moves backward, causing the linkage gear 322 to rotate, which makes the sliding block 34 move forward. This allows the clamping plate 36 to extend into the outer shell 3. The main control line 38 continues to pull the push control ring 32 backward, causing the push control ring 32 to contact the rotation control ring 33, which in turn drives the rotation control ring 33 to move backward. The rotation control ring 33 moves backward, which pulls the four clamping plates 36 inward through the pull rope 37, thereby clamping the indwelling ureter. After clamping the indwelling ureter, the indwelling ureter is returned to its original position, thus completing the entire process.
