Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a portable cystourethral endoscopy device. Background Technology

[0002] In current clinical practice, we frequently encounter emergency patients with urinary retention and urethral injury. For patients with urethral stricture, urethral endoscopy (also known as urethroscopy) is necessary to identify the location of the stricture. Current urethral endoscopy requires specific hardware (monitor, cold light source, cystoscope sheath, etc.) and a specific operating room, and the patient needs specific positioning and a positioning frame. Existing urethral endoscopy equipment lacks the mobility, flexibility, and timeliness required for bedside operation. Especially in emergencies where timely coordination of urethral endoscopy instruments is impossible, if the patient cannot undergo rapid bedside urethral endoscopy to assist with indwelling catheterization, the patient may be forced to undergo suprapubic cystostomy, resulting in trauma. In cases where catheterization is difficult and requires the assistance of a cystourethroscope or ureteroscope, medical staff must perform the procedure in the aforementioned specific operating room, not at the patient's bedside. Furthermore, routine urethral endoscopy requires continuous flushing of saline solution into the patient's urethra. The saline solution can splash throughout the entire working area of ​​a urethral endoscopy. If performed at the patient's bedside, this could lead to contamination of the instrument with the patient's bodily fluids, and even cross-infection between patients.

[0003] Patent document CN211749517U discloses a portable visual catheterization device, including: a zero-degree lens, a urethroscope housing, a water outlet, an optical fiber channel, a water channel, a finger buckle, a display, a water inlet, a water control valve, a guidewire insertion device, a water inlet hose, a tearable sheath, and a water valve device. This patented catheterization system provides full visualization and ensures a clear field of view. The entire operation can be completed in the ward or dressing room, making it highly practical. However, the patent has a drawback: it does not consider the splashing of saline solution or patient bodily fluids during saline rinsing. The patent lacks equipment to prevent splashing of waste fluid and to treat residual waste fluid, making it prone to splashing into the entire operating area for medical staff when used at the patient's bedside. This can lead to contamination of monitoring instruments by patient bodily fluids and even cross-infection between patients in adjacent beds. Therefore, this patented device cannot be used in the patient's ward; the patient still needs to coordinate with a dedicated equipment operating room for catheterization.

[0004] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not possess the features of these prior art. On the contrary, this utility model already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0005] Existing technologies have developed solutions to prevent contamination of examination instruments by incorporating protective sheath structures. For example, patent document CN203619528U discloses a disposable urethral and cystoscope sheath, which includes a scope protection section and a connecting protective section connected to the scope protection section. This solution utilizes an accommodating through-hole, a connecting through-hole, a first branch tube, a second branch tube, a connecting working channel, and a working channel to enclose the urethral and cystoscope and the instruments required for surgery, ensuring that the urethral and cystoscope does not come into direct contact with the human body. The urethral and cystoscope can thus be used directly within the disposable sheath without sterilization, avoiding the problems of long cleaning and sterilization times and damage to the urethral and cystoscope during the cleaning and sterilization process. However, the protective sheath in this solution is only located at the operating end of the urethral and cystoscope sheath to protect the external power cord and light source of the urethral and cystoscope. This structure cannot form a sealed area at the examination end, which directly contacts the urethra, to prevent splashing and disposal of waste liquid, thus preventing direct use in the patient's ward.

[0006] To address the shortcomings of existing technologies, the present invention provides a portable cystourethroscope examination device. This device includes a urethroscope body for catheterization of a patient and a protective assembly for housing the urethroscope body. The protective assembly is fitted onto the urethroscope body and forms an internal cavity to prevent fluid splashing. A first opening at the connection between the protective assembly and the urethroscope body is provided with a locking member to limit the displacement of the urethroscope body. The locking member includes an annular ring arranged circumferentially along the first opening and a plurality of flexible sheets connected to the annular ring and arranged circumferentially along the annular ring. Compared with the prior art, the urethroscope body of the present invention has a protective assembly forming an internal cavity to prevent fluid splashing on the outer side of the end used for urethral examination. The protective assembly is detachably connected to the urethroscope body via the locking member to limit the displacement of the urethroscope body.

[0007] Based on the aforementioned distinguishing technical features, the technical problem to be solved by this utility model may include: how to provide a closed examination environment during urethral examination to prevent waste liquid generated during the examination from splashing onto the examination environment and the examination operation end of medical personnel.

[0008] Specifically, this invention provides a protective component on the outer side of the end of the urethral endoscope body near the patient's examination site, which creates a relatively closed examination environment for the patient's examination site during the urethral examination. This avoids the need to perform the examination in an open environment in a dedicated operating room, thereby improving the efficiency of the urethral examination while ensuring that the actual examination environment meets the requirements.

[0009] Furthermore, this utility model enables quick assembly and disassembly of the protective component and the urethral endoscope body through a detachable locking mechanism on the protective component. This allows for rapid disinfection of the urethral endoscope body and replacement of the new protective component after the examination, thereby improving the efficiency of the examination equipment.

[0010] In addition, this utility model can limit the urethral endoscope body with the protective component inserted through the first opening, thereby fixing and locking the urethral endoscope body and the protective component. This isolates the eyepiece part of the urethral endoscope body from the protective component, preventing the entire urethral endoscope body from accidentally sliding into the protective component during subsequent operations by medical personnel.

[0011] According to a preferred embodiment, when the cylindrical urethroscope body is not inserted into the annular ring along the axial direction, a number of flexible sheets maintain their extension toward the center of the annular ring based on their own elasticity; after the cylindrical urethroscope body is inserted into the annular ring along the axial direction, the number of flexible sheets will be forced to lean against the outer wall of the urethroscope body at an incline toward the inside of the protective component due to the pushing action of the outer wall of the urethroscope body.

[0012] Preferably, when the cylindrical urethral endoscope body is not axially inserted into the annular ring, the flexible sheet can be positioned in a manner that tends to converge toward the center of the annular ring. Preferably, after the cylindrical urethral endoscope body is axially inserted into the annular ring, the flexible sheet can be positioned on the annular ring of the locking member at an angle to the central axis of the urethral endoscope body.

[0013] When the locking member is installed on the urethral endoscope body, the free end of the flexible sheet can contact the outer periphery of the urethral endoscope body in a deformable manner. Compared with the prior art, the locking member of this utility model is provided with several flexible sheet structures that can move relatively on the outer periphery of the urethral endoscope body, and there is a certain distance between adjacent flexible sheets.

[0014] Based on the aforementioned distinguishing technical features, the technical problem to be solved by this utility model may include: how to improve the stability of the flexible sheet when in contact with the urethral endoscope body. Specifically, with this arrangement, when the urethral endoscope body enters the working area inside the protective assembly through the first opening, due to the elastic force exerted by the urethral endoscope body being placed in the first opening and the annular ring compressing several flexible sheets, the urethral endoscope body is locked in the first opening to prevent accidental slippage.

[0015] According to a preferred embodiment, the urethral endoscope body is provided with a locking switch for engaging with a ring. The locking switch has a positioning portion protruding from the urethral endoscope body. The ring has a snap-fit ​​portion for engaging with the positioning portion. The locking switch is connected to a locking member by engaging the positioning portion with the snap-fit ​​portion. Compared to the prior art, the locking member in this invention can be detachably connected to the urethral endoscope body via the locking switch.

[0016] Based on the aforementioned distinguishing technical features, the technical problem to be solved by this utility model may include: how to achieve rapid positioning and disassembly of the protective components to improve the replacement efficiency of the protective components. Specifically, this utility model uses the locking switch on the urethral endoscope body and the engagement of the ring to limit the forward and backward movement of the urethral endoscope, ensuring that the patient's bodily fluids or saline solution after cleaning will not splash onto the external area, thus ensuring that medical personnel can use the portable device of this utility model to perform urinary catheterization and drainage at the patient's bedside.

[0017] According to a preferred embodiment, the latching portion is provided with at least two limiting edges that engage the positioning portion within the latching portion. The two limiting edges are such that after the positioning portion is placed inside the latching portion, the limiting edges can hold the positioning portion within the latching portion.

[0018] According to a preferred embodiment, the protective assembly further includes a diaphragm for dividing the cavity formed inside the protective assembly into a working area and a sealed area to prevent fluid from the sealed area from splashing into the working area. This invention divides the internal cavity of the protective assembly into a working area and a sealed area, preventing contamination of the eyepiece portion of the urethral endoscope body by patient bodily fluids or saline solution after cleaning. The sealed area, which is in direct contact with the patient, is separated from the working area where medical personnel operate the urethral endoscope body, thereby avoiding potential splashing of waste fluid.

[0019] According to a preferred embodiment, the diaphragm is provided with a hole connecting the working area and the closed area. After the urethroscope body enters the protective assembly through the first opening, it can enter the closed area from the working area by passing through the hole in the diaphragm. The hole in this invention can be used to restrict the position of the urethroscope body between the working area and the closed area, limiting the insertion direction of the urethroscope body, thereby preventing the urethroscope body from being accidentally moved to other areas and puncturing the protective assembly during operation by medical personnel.

[0020] According to a preferred embodiment, the protective component further includes a second opening disposed in the sealed area for accommodating the patient's genitals. The second opening is provided with a circumferentially extending pull member for tightening and fixing the second opening to the patient's coronal sulcus region of the penis, and an annular cavity for accommodating the pull member. The pull member, made of an elastic material, extends along the hollow annular cavity, and its two ends protrude from the openings of the annular cavity. The second opening can gradually tighten under the stretching action of the pull member to fix it to the patient's coronal sulcus region of the penis.

[0021] According to a preferred embodiment, the protective component further includes a third opening disposed in the sealed area for discharging waste liquid. The third opening is provided with a movable switch connector for waste liquid collection. The movable switch connector is connected to a waste liquid collection device. The third opening of this invention is connected to the waste liquid collection device, thereby centrally collecting physiological saline or patient bodily fluids after rinsing the urethral opening, which can be used for patient laboratory work while preventing waste liquid leakage.

[0022] According to a preferred embodiment, a urethroscope body made of smooth silicone material has an eyepiece passage extending along the axial direction of the urethroscope body for observing the patient's urethra and an operating passage for inserting a guide to guide urinary catheterization. The eyepiece passage and the operating passage are close to each other, parallel to each other, but not connected inside the urethroscope body. The eyepiece passage is connected to a scope body for displaying the field of view of the patient's urethra. This invention allows the medical staff to directly view the patient's urethra through the eyepiece passage and scope body, eliminating the need to go to a dedicated equipment operating room, thus offering portability and convenience.

[0023] According to a preferred embodiment, the opening of the working passage is located at the end of the urethral endoscope body near the patient's urethral orifice, in order to inject fluid into the patient's urethra. A guide device and a water inlet device are connected to the working passage at the end of the urethral endoscope body furthest from the patient. The "T"-shaped structure of the working passage at this location allows it to function as both a water inlet and a guide device. The guide device can be inserted into the working passage, and physiological saline can be injected through the water inlet to rinse the patient's urethra. Attached Figure Description

Detailed Implementation

[0032] The following is a detailed explanation with reference to the accompanying drawings.

[0033] While portable urethral endoscopes exist for catheterization and drainage in existing technologies, their application is limited by their structural design. If medical personnel directly use existing portable urethral endoscopes for bedside procedures, the need to wash the patient's urethral opening with saline solution during catheterization or examination inevitably soils bed sheets and blankets, reducing patient comfort and increasing the workload of nurses or caregivers. Therefore, this invention aims to provide a portable cystourethral endoscopy device suitable for bedside procedures.

[0034] This application relates to a portable cystourethroscope examination device. For example... Figure 1 As shown, the device includes a urethral endoscope body 100 and a protective assembly 200. The generally cylindrical urethral endoscope body 100 extends axially (from left to right in the figure) into the transparent or semi-transparent flexible protective assembly 200 to confine the fluid during operation within the flexible cavity formed by the protective assembly 200.

[0035] The protective component 200, made of sterile plastic, is a hollow bag-shaped structure with a quarter-circle outer contour. The cylindrical urethral endoscope body 100 is inserted into an opening on the curved surface of the protective component 200 at its end, which has a viewing lens, along the radial direction of the protective component 200 with its quarter-circle outer contour (from...). Figure 1 The insertion method (from left to right) protects the urethral endoscope body 100 within the internal cavity of the protective component 200, thereby preventing the patient's bodily fluids from splashing to the outside after the urethral endoscope body 100 is inserted into the patient's urethral opening.

[0036] like Figure 4 The schematic cross-sectional view of the urethral endoscope body 100 shown shows that the urethral endoscope body 100, made of smooth silicone material, has an eyepiece passage 101 and a working passage 102 extending along its axis. The urethral endoscope body 100, with a cylindrical outer contour and a smooth arc surface at one end near the patient's urethra, can be inserted into the patient's urethra as an outer sheath.

[0037] like Figure 4 and Figure 5 As shown, the eyepiece passage 101, with a circular cross-section forming a cylindrical channel, and the working passage 102, with a crescent-shaped cross-section forming an irregular channel, are located inside the urethral endoscope body 100 and extend along the axial direction of the urethral endoscope body 100. Thus, the eyepiece passage 101 and the working passage 102, which are close to each other, parallel but not connected, can maximize the use of the internal space of the cylindrical urethral endoscope body 100, reducing the operational difficulty for medical personnel.

[0038] For patients, the design of the urethroscope directly affects the comfort and safety during examination or treatment. The cylindrical eyepiece passage 101 and the irregularly shaped working passage 102 maximize the use of the internal space of the urethroscope body 100, reflecting the designers' optimization of the internal space utilization of the urethroscope. This makes the entire operation process more precise and stable for medical personnel, reduces additional trauma caused by improper operation, improves the safety of treatment, and also reduces production costs to some extent.

[0039] Preferably, the eyepiece passage 101, made of a soft metal material, has a lens for acquiring images of the patient's urethra at its end near the urethral opening. The smooth, rounded surface of the urethral endoscope body 100 near the patient is made of a smooth and transparent material, allowing the lens located within the urethral endoscope body 100 to acquire images of the patient's urethral opening or urethra. The eyepiece passage 101, extending from the inside of the urethral endoscope body 100 to the outside, is connected to the endoscope body 103. The endoscope body 103 is used to display the field of view at the patient's urethra based on the image data. The endoscope body 103, located on the outside, can be threadedly connected to the eyepiece passage 101 or connected in other detachable ways, so that when medical personnel inject saline through the inlet 105 of the working passage 102, the endoscope body 103 can be separated from the eyepiece passage 101, preventing waste liquid from contaminating the optical fiber in the endoscope body 103.

[0040] The endoscope 103 not only has the important function of observing urethral images, but also can be separated from the eyepiece passage 101 by means of a detachable connection, thereby effectively avoiding the contamination of the optical fiber in the endoscope 103 by waste liquid.

[0041] Preferably, the eyepiece passage 101 and the endoscope body 103 are detachably connected, and the detachable connection is made of a soft metal material, allowing the eyepiece passage 101 to stably support the endoscope body 103 and ensure its stability during surgery. This detachable connection, made of soft metal, also possesses a degree of flexibility. This means that medical personnel can make slight adjustments to the endoscope body 103 during actual operation to adapt to different surgical needs and observation angles, thereby more accurately observing the patient's urethral image and providing strong support for the smooth progress of the surgery.

[0042] Preferably, the working passage 102, located inside the urethroscope body 100, is disposed through the urethroscope body 100, with its opening located at the anterior end of the urethroscope body 100 near the patient. A tee-like adapter is connected to the end of the urethroscope body 102 away from the patient to form a "T"-shaped structure at that location. The tee-like adapter of the working passage 102 is connected to both a guide device and a water inlet device, thereby allowing the working passage 102 to function as both a water inlet 105 and a device for operating the guide 104. Medical personnel can insert the guide 104 through the working passage 102, penetrating the urethroscope body 100, or inject saline solution into the patient's urethral opening through the working passage 102. The guide 104 can be inserted into the working passage 102, and saline solution can be injected through the water inlet 105 to rinse the patient's urethra. Preferably, the guide 104 is, for example, a guidewire. The layout of the workflow 102 is well-designed, allowing nurses to more easily prepare and deliver necessary instruments while ensuring the smooth execution of aseptic procedures. Furthermore, the reduced complexity of the workflow means nurses can respond more quickly to the needs of medical staff, improving the overall efficiency of the healthcare team.

[0043] As described above, the design of the eyepiece passage 101 and the working passage 102 in the urethral endoscope body 100 of this utility model has shown significant technical effects in terms of improving operating efficiency, reducing patient discomfort, enhancing the doctor's operating experience, and optimizing design costs.

[0044] Preferably, the hollow bag-shaped protective component 200 has a first opening 201 for accommodating the urethroscope body 100 and a second opening 202 for placing the patient's genitals. Both the first opening 201 and the second opening 202 are circular openings to match the outer contours of the urethroscope body 100 and the patient's genitals.

[0045] like Figure 2 and Figure 3 As shown, a locking member 205 is provided at the first opening 201 where the protective component 200 connects to the urethral endoscope body 100. The locking member 205 may include an annular ring 206 arranged circumferentially along the first opening 201 and a plurality of flexible sheets 207 connected to the annular ring 206 and arranged circumferentially thereon.

[0046] Preferably, when the cylindrical urethral endoscope body 100 is not inserted axially into the annular ring 206, a plurality of flexible sheets 207 extend toward the center of the annular ring 206 based on their own elasticity, so that the first opening 201 is closed by the stacked plurality of flexible sheets 207. Further, a plurality of flexible sheets 207 in the shape of rectangles, ellipses, or other leaflets are attached to the circumference of the annular ring 206 so that the plurality of flexible sheets 207 close the circle formed by the annular ring 206, that is, the plurality of flexible sheets 207 can be arranged in a manner that has a tendency to converge toward the center of the annular ring 206.

[0047] Preferably, after the cylindrical urethroscope body 100 is inserted axially into the annular ring 206, several flexible sheets 207 will be forced to lean against the outer wall of the urethroscope body 100 at an incline towards the inside of the protective assembly 200 due to the pushing action of the outer wall of the urethroscope body 100.

[0048] More preferably, when the cylindrical urethroscope body 100 enters the internal cavity of the protective assembly 200 through the circular first opening 201 in a direction perpendicular to the plane of the first opening 201, the outer periphery of the cylindrical urethroscope body 100 acts on the free ends of several flexible sheets 207 that are not connected to the annular ring 206 in a direction perpendicular to the plane of the first opening 201. This causes the several flexible sheets 207 to be subjected to a force that moves them away from the center of the annular ring 206, thereby rotating and unfolding towards the internal cavity of the protective assembly 200 with the attachment point of the annular ring 206 as the center, forming a passage for accommodating the insertion of the urethroscope body 100 into the first opening 201.

[0049] Preferably, the protective component 200 is fitted onto the urethral endoscope body 100 through the locking member 205 of the first opening 201, so that the urethral endoscope body 100 enters the working area 215 formed inside the protective component 200 through a plurality of flexible sheets 207, annular rings 206 and the first opening 201.

[0050] With this configuration, when the urethral endoscope body 100 enters the working area 215 inside the protective assembly 200 through the first opening 201, the urethral endoscope body 100, being placed in the first opening 201 and the annular ring 206, compresses several flexible sheets 207 away from the center of the annular ring 206. This compression action of the flexible sheets 207 locks the urethral endoscope body 100 in the first opening 201 to prevent it from accidentally slipping out.

[0051] Preferably, such as Figure 1The diagram shows a cross-sectional view of the urethroscope body 100 after the protective component 200 has been inserted (only the outer layer of the protective component 200 is cut to show its internal structure). The second opening 202 of the protective component 200 can be a narrowed pocket provided on the protective component 200, which gradually tightens under the stretching action of the pull member 213 extending circumferentially along the second opening 202 to fix the protective component 200 to the coronal sulcus of the patient's penis, thereby forming a sealed area 216 in the internal cavity to prevent splashing of waste fluid. A ring cavity 217 is provided circumferentially in the second opening 202 to accommodate the pull member 213. The pull member 213, made of an elastic material, extends along the hollow ring cavity 217, and both ends of the pull member 213 protrude from the opening of the ring cavity 217. Preferably, the pull member 213 can be an elastic rope. Medical personnel can change the size of the second opening 202 by stretching the two ends of the pull member 213 extending from the annular cavity 217 and tying the pull member 213 in a way that causes the annular cavity 217 of the second opening 202 to contract, so that the size of the second opening 202 matches the coronal sulcus area of ​​the patient's penis.

[0052] Furthermore, such as Figure 1 As shown, the protection assembly 200 also includes a third opening 203 for connection to the waste fluid collection assembly. The third opening 203 is provided with a movable switch connector 214 to enable it to be connected to the waste fluid collection device, thereby collecting saline solution or patient bodily fluids after rinsing the urethral opening, and using it for patient laboratory work while preventing waste fluid leakage.

[0053] Preferably, the protective assembly 200 further includes a diaphragm 204 for dividing the internal cavity of the protective assembly 200 into a working area 215 and a sealed area 216. Preferably, as Figure 1 As shown, the diaphragm 204 inside the protective assembly 200 is provided with a hole 212 connecting the working area 215 and the sealed area 216. When the urethroscope body 100 enters the protective assembly 200 through the first opening 201, it can enter the sealed area 216 by passing through the hole 212 on the diaphragm 204. Therefore, the urethroscope body 100 can move in a limited manner, restricted by the first opening 201 and the hole 212, to prevent contamination of the endoscope body 103 of the urethroscope body 100 by patient bodily fluids or saline solution after washing.

[0054] Furthermore, the hole 212 on the diaphragm 204 corresponds to the position of the first opening 201, ensuring that it does not obstruct the entry of the urethroscope body 100 into the sealed area 216. Because the cavity formed inside the protective component 200 is relatively large, if the forward direction of the urethroscope body 100 is not restricted, it may cause the urethroscope body 100 to puncture the protective component 200 made of sterile plastic material. Therefore, this invention, through the hole 212 on the diaphragm 204, not only restricts the forward direction of the urethroscope body 100 but also prevents waste fluid from the sealed area 216 from splashing into the working area 215.

[0055] The orifice 212 of this invention can be used to restrict the position of the urethroscope body 100 between the working area 215 and the sealed area 216, limiting the insertion direction of the urethroscope body 100, thereby preventing the urethroscope body 100 from being accidentally moved to other areas and puncturing the protective component 200 during operation by medical personnel. Furthermore, the diaphragm 204 can also divide the interior of the protective component 200 into the working area 215 and the sealed area 216, separating the sealed area 216, which is in direct contact with the patient, from the working area 215 where medical personnel operate the urethroscope body 100, thereby preventing potential splashing of waste fluid. In addition, the orifice 212 may also have an axially extending bushing (not shown in the figure), which guides the movement of the urethroscope body 100 and further enhances the sealing effect. Preferably, the bushing can extend axially toward one or both sides towards the patient or doctor. Preferably, the bushing has a diameter that decreases axially toward the patient side to facilitate insertion and further enhance the sealing effect.

[0056] Furthermore, such as Figure 3 As shown, the urethroscope body 100 is provided with a plate-shaped locking switch 209 that can be connected to the annular ring 206. The locking switch 209, located at the point where the eyepiece passage 101 contacts the outside, has a spherical positioning part 210 protruding from the urethroscope body 100; that is, the positioning part 210 is a spherical protrusion. The annular ring 206 has a snap-fit ​​part 208 for engaging with the positioning part 210 on the locking switch 209 in a snap-fit ​​manner. The positioning part 210 can be a groove. The arrangement of the positioning part 210 and the snap-fit ​​part 208 ensures a secure connection between the urethroscope body 100 and the annular ring 206, preventing loosening or detachment. The design of the locking switch 209 allows medical personnel to easily connect or disconnect it from the annular ring 206, improving the convenience of using the urethroscope. Clip-on connections are generally more durable and can withstand repeated insertion and removal, thus extending the lifespan of the urethroscope.

[0057] Since the annular ring 206 can be made of a flexible material, the diameter of the contact portion of the snap-fit ​​portion 208 with the positioning portion 210 can be smaller than the diameter of the positioning portion 210, so that when the snap-fit ​​portion 208 and the positioning portion 210 are snapped together, the spherical positioning portion 210 of the locking switch 209 is restricted within the snap-fit ​​portion 208.

[0058] Preferably, such as Figure 6 As shown, the latching portion 208 can be provided with at least two limiting edges 211 so that after the positioning portion 210 is placed inside the latching portion 208, the elastic limiting edges 211 can lock the positioning portion 210 inside the latching portion 208. Both the latching portion 208 and the limiting edges 211 have a certain degree of extensibility, so that the positioning portion 210 can be placed inside the smaller diameter latching portion 208 by compression and restricted by the limiting edges 211.

[0059] Specifically, such as Figure 6 As shown, the positioning part 210 can be a sphere protruding from the locking switch 209. The semicircular portion of the positioning part 210 can be fixedly connected to the locking switch 209 so that it protrudes from the locking switch 209. Preferably, one-third of the spherical volume of the positioning part 210 is fixedly connected to the locking switch 209, such that at least two-thirds of the volume of the positioning part 210 protrudes from the locking switch 209. Since the annular ring 206 is made of a flexible material, the snap-fit ​​portion 208 on it also has a certain degree of extensibility. The positioning part 210 can be placed in and engaged with the smaller diameter snap-fit ​​portion 208 by compression. Thus, when the positioning part 210 is placed in the snap-fit ​​portion 208, the positioning part 210 can engage with the snap-fit ​​portion 208 under the limiting action of the limiting edge 211, thereby connecting the locking switch 209 to the locking member 205. The limiting edge 211 is used to prevent medical personnel from accidentally pulling out the urethral endoscope body 100 without their consent, thereby enhancing the connection stability between the urethral endoscope body 100 and the protective component 200.

[0060] In summary, the design of the urethral endoscope locking mechanism of this utility model, by adding a limiting edge 211 and optimizing the shape of the positioning part 210, improves the stability of the connection, the convenience of operation, the safety of use, and the durability and adaptability of the device, providing more reliable technical support for medical operations.

[0061] This invention limits the vertical and horizontal movement of the urethral endoscope body 100, which is inserted into the protective component 200, through the first opening 201. Furthermore, it limits the front and rear movement of the urethral endoscope by engaging the locking switch 209 of the urethral endoscope body 100 with the annular ring 206 of the protective component 200. This achieves a fixed lock between the urethral endoscope body 100 and the protective component 200, isolating the endoscope body 103 from the protective component 200 and preventing the urethral endoscope body 100 from sliding into the protective component 200 during subsequent medical procedures. Moreover, the connection method between the protective component 200 and the urethral endoscope body 100 ensures that the patient's bodily fluids or saline solution after cleaning will not splash onto the external area, allowing medical personnel to use this portable device at the patient's bedside for catheterization and drainage.

[0062] To address the issue of leakage or splashing of bodily fluids or injected saline solution during catheterization, this application's urethral endoscope incorporates improvements in the design of the protective component 200, interface design, and portability. The protective component 200 is designed for single-use and is made of waterproof plastic.

[0063] Therefore, this utility model restricts the displacement and direction of the urethral endoscope body 100 with the protective component 200 inserted from three aspects: hole 212, locking member 205 and locking switch 209, so as to avoid the possibility of the urethral endoscope body 100 slipping out due to misoperation.

[0064] Existing technologies for urethral monitoring require specific hardware combinations (e.g., monitors, cold light sources, cystoscope sheaths, etc.). Because this hardware combination requires large equipment such as cold light sources and cystoscopes, and necessitates the deployment of multiple nurses, a dedicated equipment operating room is required for urethral monitoring. Especially during these procedures, continuous saline rinsing is required, causing splashing of patient fluids and the rinse saline solution into the work area 215; therefore, a dedicated equipment operating room is essential. Patients requiring catheterization need to be transported to this dedicated operating room, but this process requires at least a 1-hour coordination window. For patients requiring emergency treatment, whose bladders may be overdisplaced and who cannot tolerate the long waiting time, invasive drainage may be necessary. Medical staff can utilize the portable device of this invention to perform bedside catheterization within 5-10 minutes. The diaphragm 204 of this invention separates the work area 215 from the sealed area 216 to prevent waste fluid leakage, while also avoiding contamination of the instrument by body fluids, reducing cross-infection between patients, and ensuring high safety.

[0065] To facilitate understanding, the working principle and usage of this portable cystourethral endoscopy device will be discussed.

[0066] First, medical personnel tighten and fix the second opening 202 of the protective component 200 to the coronal sulcus of the patient's penis by pulling the pull member 213. After tightening the pull member 213, the medical personnel tie a knot to secure the patient's genitals. The medical personnel insert the urethral endoscope body 100 into the protective component 200 through the first opening 201, and then insert the urethral endoscope body 100 into the sealed area 216 through the hole 212 on the diaphragm 204. After confirming that the orientation and position of the urethral endoscope body 100 are correct, the medical personnel engage the positioning part 210 of the locking switch 209 on the urethral endoscope body 100 with the snap-fit ​​part 208 on the annular ring 206, thereby fixing the protective component 200 to the urethral endoscope body 100, thus combining the urethral endoscope body 100 with the protective component 200 from multiple angles. Medical personnel can observe the patient's urethra through the endoscope 103 connected to the eyepiece passage 101 of the urethral endoscope body 100, and guide the insertion of the guide 104 through the working passage 102 of the urethral endoscope body 100 for guidance, or inject physiological saline through the working passage 102. The protective component 200 of this invention can prevent the spillage or splashing of waste liquid, enabling timely, flexible, and mobile bedside operations. Furthermore, as a disposable, replaceable sterile kit, the protective component 200 can prevent contamination of the instrument by the patient's bodily fluids, reduce cross-infection between patients, and ensure high safety.
