Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a rigid urinary endoscope. Background Technology

[0002] A rigid urinary endoscope is a medical device used for internal examinations and surgeries, primarily composed of a metal tube, optical lenses, and an illumination system. Like a slender "metal telescope," it can be inserted into the body through natural cavities or tiny incisions, allowing physicians to directly observe the actual condition of organs or tissues. Compared to flexible endoscopes, its tube cannot be bent, but it provides clearer images and has a longer lifespan.

[0003] In related technologies, the stability and comfort of the surgeon's hands are key factors affecting the use of rigid urinary endoscopic surgery. However, many surgeons experience excessive sweating of the hands, which causes numerous difficulties in surgical procedures. Sweat can cause the surgeon's hand to slip on the handle of the rigid urinary endoscopic endoscope, leading to instability in the surgical procedure and increasing surgical risks. Especially during delicate procedures, slippage can lead to serious accidents. Summary of the Invention

[0004] This application provides a rigid urinary endoscope designed to at least partially improve the stability and comfort of the physician's hand, thereby ensuring surgical efficiency and quality.

[0005] This application is achieved through the following technical solution: A rigid urinary endoscope includes: a tubing having a gripping end; a handle connected to the gripping end of the tubing; and an anti-slip assembly including a blower and an anti-slip sleeve, wherein the blower is connected to the handle, the anti-slip sleeve is fitted onto the handle, the anti-slip sleeve has an air-guiding cavity, and the outer peripheral surface of the anti-slip sleeve has multiple air-guiding holes, the air-guiding cavity communicating with the output part of the blower and the multiple air-guiding holes respectively.

[0006] In some implementations, the fan has a built-in heating element.

[0007] In some embodiments, the anti-slip sleeve and the fan are sequentially connected to the handle along the axial direction of the pipe. The anti-slip sleeve has an air inlet at the end facing the fan, which is connected to the air intake chamber. The air outlet side of the fan is in close contact with the anti-slip sleeve, and the air outlet side of the fan has a connecting hole that is opposite to and connected to the air inlet.

[0008] In some embodiments, the outer peripheral surface of the anti-slip sleeve is provided with a plurality of grooves, the grooves being provided along the axial direction parallel to the pipe or around the peripheral surface of the anti-slip sleeve, and the bottom of the grooves being provided with a plurality of air inlet holes.

[0009] In some embodiments, the anti-slip component further includes a guide member disposed within the groove, and the guide member does not protrude from the outer peripheral surface of the anti-slip sleeve, wherein: the guide member and the air duct are provided in a one-to-one correspondence, the guide member is disposed outside the corresponding air duct, and the guide member is inclined to the axial direction of the anti-slip sleeve.

[0010] In some implementations, the distance between the guide and the central axis of the anti-slip sleeve increases sequentially along the direction from the pipe to the grip.

[0011] In some embodiments, the guide member is provided with a plurality of guide holes, the central axis of the plurality of guide holes being inclined to the radial direction of the anti-slip sleeve.

[0012] In some embodiments, the rigid urinary endoscope further includes an adjustment assembly, which is correspondingly arranged with the air inlet. One end of the adjustment assembly is movably inserted into the air inlet, and the adjustment assembly has a sealing portion. The other end of the adjustment assembly moves within the groove and protrudes from the outer peripheral surface of the anti-slip sleeve. The adjustment assembly has a switchable first state and a second state. In the first state, the gap of the sealing portion is located outside the corresponding air inlet, and the other end of the adjustment assembly protrudes from the outer peripheral surface of the anti-slip sleeve. In the second state, the sealing portion moves towards the corresponding air inlet, and the other end of the adjustment assembly is recessed within the groove.

[0013] In some embodiments, the adjusting assembly includes: a connecting plate adapted to be movably disposed within the groove; a moisture-absorbing plate connected to the outer side of the connecting plate, the moisture-absorbing plate protruding from the outer peripheral surface of the anti-slip sleeve; a flow-limiting column connected to the inner side of the connecting plate, the outer diameter of the flow-limiting column being greater than or equal to the inner diameter of the air inlet; and an elastic element connecting the flow-limiting column and the anti-slip sleeve.

[0014] In some embodiments, the adjusting assembly further includes: a guide sleeve connected to the inner side of the flow-limiting column, the guide sleeve being spaced within the corresponding air intake hole; a connecting rod connected to the bottom of the groove of the air intake hole, the connecting rod and the guide sleeve being movably inserted; wherein, the elastic element is sleeved on the guide sleeve and the connecting rod.

The air-guiding cavity is connected to the output part of the fan and the multiple air-guiding holes. Therefore, when a physician uses the rigid urinary endoscope, the physician holds the handle and starts the fan. The fan introduces air and delivers it to the air-guiding cavity of the anti-slip sleeve, and then sprays air through the air-guiding holes on the anti-slip sleeve onto the physician's hand. This quickly evaporates the sweat from the physician's hands, keeping them dry, improving the stability and comfort of the physician's hands, and ensuring surgical efficiency and quality.

Detailed Implementation

[0018] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Clinically, a rigid urinary endoscope is a tool used in minimally invasive endoscopic techniques. It can be inserted into the body through natural cavities or tiny incisions to help physicians directly observe the actual condition of organs or tissues. Compared to a flexible endoscope, its tube cannot be bent, but it provides clearer images and has a longer lifespan.

[0020] In related technologies, the stability and comfort of the surgeon's hands are key factors affecting the use of the rigid urinary endoscope 10 during surgery. However, many surgeons experience excessive sweating of the hands, which causes numerous problems during surgical procedures. On the one hand, sweat can cause the surgeon's hand to slip on the handle of the rigid urinary endoscope 10, leading to instability in surgical operations and increasing surgical risks, especially during delicate procedures where slippage can cause serious accidents. On the other hand, in low ambient temperatures, the surgeon's hand temperature decreases, reducing finger dexterity and affecting the stability and operability of the surgeon's hand, resulting in slow surgical procedures and impacting surgical efficiency and quality.

[0021] Based on the above-mentioned technical problems, this application provides a urinary rigid endoscope 10, which aims to improve the stability and comfort of the physician's hand to at least a certain extent, and ensure the efficiency and quality of surgery.

[0022] Figure 1 A schematic diagram of the structure of a rigid urinary endoscope 10 according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 An explosion diagram. Figure 3 It shows Figure 1A schematic diagram of the anti-slip component 130 in the middle. Figure 4 It shows Figure 3 A schematic diagram of the protective sleeve. (Combined with...) Figures 1-4 The urinary rigid endoscope 10 provided in this application includes a tube 110, a handle 120, and an anti-slip component 130. The tube 110 has a gripping end; the handle 120 is connected to the gripping end of the tube 110; the anti-slip component 130 includes a blower 131 and an anti-slip sleeve 132. The blower 131 is connected to the handle 120, and the anti-slip sleeve 132 is fitted onto the handle 120. The anti-slip sleeve 132 is provided with an air-guiding cavity 133, and a plurality of air-guiding holes 134 are opened on the outer peripheral surface of the anti-slip sleeve 132. The air-guiding cavity 133 is connected to the output part of the blower 131 and the plurality of air-guiding holes 134 respectively.

[0023] The rigid urinary endoscope 10 provided in this application has an anti-slip component 130 that includes a fan 131 and an anti-slip sleeve 132. The fan 131 is connected to the handle 120, and the anti-slip sleeve 132 is fitted onto the handle 120. The anti-slip sleeve 132 is provided with an air intake cavity 133, and multiple air intake holes 134 are opened on the outer peripheral surface of the anti-slip sleeve 132. The air intake cavity 133 is connected to the output part of the fan 131 and the multiple air intake holes 134. Therefore, when the physician uses the rigid urinary endoscope 10, the physician holds the handle 120 and starts the fan 131. The fan 131 introduces air and delivers it into the air intake cavity 133 of the anti-slip sleeve 132, and sprays it onto the physician's hand through the air intake holes 134 on the anti-slip sleeve 132 to quickly evaporate the sweat on the hands, keep the physician's hands dry, improve the stability and comfort of the physician's hands, and ensure the efficiency and quality of the operation. The specific details of the urinary rigid endoscope 10 are now described in further detail with reference to the accompanying drawings.

[0024] In related technologies, the temperature in operating rooms is usually controlled at a low level to prevent bacterial growth and ensure the stability of the surgical environment. However, in such a low-temperature environment, the temperature of the surgeon's hands will also decrease. Low hand temperature can reduce finger dexterity and slow muscle reaction speed, potentially leading to delays in surgical procedures. During delicate and complex surgical procedures, this delay may cause missed opportunities, affecting surgical outcomes and even endangering the patient's life. Therefore, in some implementation schemes, the fan 131 has a built-in heating element. When activated, the fan 131 draws in external air, heats it, and delivers it to the anti-slip sleeve 132. The air is then expelled through air vents 134 on the surface of the anti-slip sleeve 132, providing continuous airflow to the surgeon's hands during surgery. Simultaneously, the heating temperature can be maintained at a normal temperature, such as 25-30°C. This efficiently evaporates sweat from the surgeon's hands, preventing delays in surgical procedures caused by low hand temperature in low ambient temperatures, thus ensuring surgical efficiency and quality. The two ends of the tube 110 in this application are a probe end and the aforementioned gripping end, respectively. The probe end can enter the body through natural cavities or tiny incisions to help doctors directly observe the actual condition of organs or tissues. The user holds the handle 120 on the gripping end to operate the tube 110. The connection between the probe end and the handle 120 is prior art and will not be described in detail in this application.

[0025] Combination Figure 2 The grip 120 of this application has a recess in the middle of its circumferential surface, which is adapted to the anti-slip component 130. When the anti-slip component 130 is assembled onto the grip 120, the two sides of the grip 120 can limit the anti-slip component 130, so that the anti-slip component 130 can be fixed relative to the grip 120.

[0026] Combination Figure 1 as well as Figure 2 In this application, the anti-slip sleeve 132 and the blower 131 are sequentially connected to the handle 120 along the axial direction of the pipe 110. In specific implementation, the anti-slip sleeve 132 and the blower 131 are arranged sequentially in the direction away from the probe end, that is, when the rigid urinary endoscope 10 is in use, the blower 131 is located on the side of the anti-slip sleeve 132 facing away from the patient. In order to prevent the anti-slip sleeve 132 and the blower 131 from rotating relative to the handle 120, the anti-slip sleeve 132 and the blower 131 can be fixedly connected to the recess of the handle 120 by means of key connection or other means.

[0027] Figure 5 An axial side view of the anti-slip sleeve 132 in some embodiments is shown. Figure 6 An axial side view of the fan 131 is shown. (Combined with...) Figure 5 as well as Figure 6 In other embodiments, the anti-slip sleeve 132 has an air inlet 135 at its end facing the fan 131. The air inlet 135 is connected to the air intake chamber 133. The air outlet side of the fan 131 is in close contact with the anti-slip sleeve 132. The air outlet side of the fan 131 has a connecting hole 136, which is opposite to and connected to the air inlet. When the fan 131 is working, the air drawn by the fan 131 can be introduced into the air intake chamber 133 through the connecting hole 136 on the starting side and the air inlet of the anti-slip sleeve 132, and then drawn out from the air intake hole 134 of the anti-slip sleeve 132.

[0028] In some other embodiments, the anti-slip sleeve 132 may have a gap between it and the grip 120, and an air intake cavity 133 is formed between the anti-slip sleeve 132 and the grip 120. At least a portion of the starting side of the fan 131 can enter the gap between the anti-slip sleeve 132 and the grip 120 so that the air drawn out from the starting side of the fan 131 directly enters the air intake cavity 133 and is drawn out from the air intake hole 134 of the anti-slip sleeve 132.

[0029] Combination Figure 4In some embodiments, the outer peripheral surface of the anti-slip sleeve 132 is provided with multiple grooves 137. The grooves 137 are provided along the axial direction parallel to the pipe 110 or around the peripheral surface of the anti-slip sleeve 132, and the bottom of the grooves 137 is provided with multiple air inlets 134. This arrangement has two advantages: firstly, it allows the multiple air inlets 134 to be arranged in a grid pattern on the outer peripheral surface of the anti-slip sleeve 132, improving the air outlet effect and correspondingly improving the doctor's comfort; secondly, the multiple grooves 137 make the outer peripheral surface of the anti-slip sleeve 132 uneven, thereby increasing the friction between the doctor's hand and the anti-slip sleeve 132 and preventing the hand from slipping. At the same time, the grooves 137 in the anti-slip sleeve 132 provide the doctor's hand with contact area with the air, allowing doctors whose hands are prone to sweating to keep their hands dry and reducing the problem of hand slippage and instability during surgery caused by sweat between the hand and the anti-slip sleeve 132. This arrangement has good practicality.

[0030] In specific implementation, the cross section of the chute along the axial direction of the anti-slip sleeve 132 can be approximately U-shaped, and multiple grooves 137 are arranged at equal angles around the circumference of the anti-slip sleeve 132. In addition, the air inlet 134 can be a circular hole. Of course, the cross section of the chute along the axial direction of the anti-slip sleeve 132 can also be V-shaped or arc-shaped, and the air inlet 134 can be an oval hole, a square hole, etc. This application does not limit this.

[0031] Figure 7 It shows Figure 3 A magnified diagram of point A. Combined with... Figure 7 In some embodiments, the anti-slip component 130 further includes a guide member 138, which is disposed within the groove 137 and does not protrude from the outer peripheral surface of the anti-slip sleeve 132. The guide member 138 and the air inlet 134 are correspondingly arranged, with the guide member 138 positioned outside the corresponding air inlet 134 and inclined radially towards the anti-slip sleeve 132. This arrangement allows air drawn through the air inlet 134 to be guided by the guide member 138 and ejected radially towards the anti-slip sleeve 132. The original purpose of this design was to address the issue that if air were ejected directly from the air intake hole 134, i.e., along the radial direction of the anti-slip sleeve 132, the air would be ejected in a straight line with relatively high pressure, potentially causing a strong impact on the doctor's hands, leading to discomfort and affecting surgical procedures. However, the airflow guide 138 guides the air ejected from the air intake hole 134, blocking it and buffering it to the surrounding area. This transforms the point-like airflow into a surface-like blowing, reducing the air pressure and preventing discomfort caused by direct airflow onto the hands. While ensuring stable ventilation and desiccation, the airflow guide 138 also buffers the air, allowing it to reach the hands more gently over a wider area, further improving the desiccation efficiency.

[0032] In some embodiments, along the direction from the pipe 110 to the handle 120, the distance between the central axis of the guide member 138 and the anti-slip sleeve 132 increases sequentially. That is, the guide member 138 is inclined to the back of the anti-slip sleeve 132, facing away from the patient. This allows the guide plate to buffer and block the air while guiding the airflow. The air is guided along the inclined surface of the guide plate to the rear of the anti-slip sleeve 132, so that the air ejected through the air outlet 134 is evenly guided by the guide member 138 and continuously flows behind the anti-slip sleeve 132. This makes the airflow orderly, reduces the impact of turbulence on the hand, avoids hand itching and discomfort, and further ensures the stability and comfort of the simultaneous sweating surgery. It also improves the accuracy of doctors with sweaty hands during surgery and reduces the occurrence of accidents caused by hand slippage. In addition, since the guide member 138 is inclined to the back of the anti-slip sleeve 132, it can also prevent the air from flowing towards the user and avoid causing user discomfort.

[0033] Combination Figure 7 In some implementations, the air guide 138 is provided with multiple air guide holes 139. The central axis of the multiple air guide holes 139 is inclined to the radial direction of the anti-slip sleeve 132 and is roughly consistent with the inclination direction of the air guide 138. With this configuration, when air flows along the inclined surface of the air guide 138, the air guide holes on the air guide 138 can also divert the air to a certain extent, so that the air is discharged outward in a surface manner as much as possible. At the same time, the air guide holes 139 are also inclined, so that the air is blown steadily towards the hand, further improving the gentleness of sweat removal, reducing the impact on the hand, and allowing the air to flow continuously along the groove 137, and finally discharged through the opening of the groove 137 away from the patient, forming a stable air flow direction and avoiding affecting the patient who is undergoing surgery. In a specific implementation, the guide member 138 is a plate structure, which is fixedly embedded in the groove 137. There is a distance between the guide member 138 and the bottom of the groove 137 to allow airflow. The distance between the guide member 138 and the bottom of the groove 137 increases sequentially away from the conduit, so that the guide member 138 is inclinedly disposed in the groove 137. To improve the reliability of the assembly of the guide member 138 in the groove 137, the end of the guide member 138 and the side wall of the groove 137 can be further fixed by means of snap-fit ​​or key connection. In addition, the guide member 138 can have multiple guide holes 139, such as the three shown in the figure. Of course, it can also be two or four, etc., and this application does not limit this.

[0034] Combination Figure 7 In some embodiments, the urinary rigid endoscope 10 also includes an adjustment assembly 140. Figure 8 A schematic diagram of the assembly of the adjustment component 140 on the anti-slip sleeve 132 is shown. Figure 9A schematic diagram of the adjustment component 140 is shown. (Combined with...) Figures 7-9 The adjusting component 140 and the air vent 134 are arranged in a one-to-one correspondence. One end of the adjusting component 140 is movably inserted into the air vent 134. The adjusting component 140 has a sealing part 141. The other end of the adjusting component 140 moves within the groove 137. The other end of the adjusting component 140 protrudes from the outer peripheral surface of the anti-slip sleeve 132. The adjusting component 140 has a switchable first state and a second state. Figure 10 A schematic diagram of the adjustment component 140 from its first state is shown, in conjunction with... Figure 10 When the adjusting component 140 is in the first state, the gap of the sealing part 141 is located outside the corresponding air duct 134, and the other end of the adjusting component 140 protrudes from the outer peripheral surface of the anti-slip sleeve 132. Figure 11 This diagram shows the structure of the adjustment component 140 in its second state, in conjunction with... Figure 11 When the adjusting component 140 is in the second state, the sealing part 141 moves toward the corresponding air vent 134, and the other end of the adjusting component 140 is recessed into the groove 137.

[0035] When the physician holds the anti-slip sleeve 132, the sweat on the physician's hands will come into contact with the other end of the adjustment component 140. At this time, the adjustment component 140 is in the first state. Since the gap of the sealing part 141 is located outside the corresponding air vent 134, the air flowing out of the air vent 134 at the bottom of the groove 137 can be used to remove sweat from the physician's hands. When the physician is performing a very precise operation, the hand usually grips the handle 120 more tightly, and the muscles and skin of the hand will embed into the groove 137 and press against the adjustment component 140. At this time, the adjusting component 140 is in the second state. The first end of the adjusting component 140 moves into the air inlet 134, and the sealing part 141 moves in the direction of the corresponding air inlet 134, thereby reducing the exhaust volume of the air inlet 134 or even closing the air inlet 134. This reduces the interference of the blowing air to remove sweat on the doctor's hands when performing short-term, high-intensity precision operations. The doctor can keep their hands cool and dry under high-precision and stressful working conditions, while also avoiding the problem of the blowing air affecting the doctor's hands. In other words, the adjusting component 140 can automatically switch the sweat removal effect on the doctor's hands according to different working conditions.

[0036] Combination Figures 8-11The adjusting assembly 140 includes a connecting plate 142, a moisture-absorbing plate 143, a flow-limiting column 144, and an elastic element 145. The connecting plate 142 is adapted to be movably disposed in the groove 137. The moisture-absorbing plate 143 is connected to the outer side of the connecting plate 142 and protrudes from the outer peripheral surface of the anti-slip sleeve 132. The flow-limiting column 144 is connected to the inner side of the connecting plate 142. The outer diameter of the flow-limiting column 144 is greater than or equal to the inner diameter of the air duct 134. The flow-limiting column 144 is configured as a sealing part 141. The elastic element 145 connects the flow-limiting column 144 and the inner wall of the air duct 134. When the adjusting component 140 is in the first state, due to the support of the elastic element 145, the flow-limiting column 144 is positioned outside the corresponding air vent 134, without affecting the airflow at the air vent 134. When the adjusting component 140 is in the second state, due to the pressure of the physician's hand, the adjusting component 140 moves as a whole into the groove 137, and the adjusting component 140 is recessed into the groove 137. The flow-limiting column 144 moves towards the corresponding air vent 134 to reduce the flow area at the air vent 134, or even close the air vent 134, and compress the elastic element 145. As the pressure of the physician's hand decreases, the adjusting component 140 can switch from the second state to the first state under the action of the elastic element 145.

[0037] In this application, because the moisture-absorbing plate 143 is connected to the outside of the connecting plate 142, the moisture-absorbing plate 143 directly contacts the doctor's hand. When the doctor holds the heat-resistant anti-slip sleeve 132, the sweat on the doctor's hand will first come into contact with the moisture-absorbing plate 143 and be quickly absorbed by it, rapidly wiping away sweat from the hand. This allows the doctor to quickly remove some of the sweat from their hands when changing to the instrument. Subsequently, the hot air ejected from the air vent 134 not only wipes away sweat from the hand but also evaporates the sweat from the connecting plate 142, avoiding the problem of slow sweat evaporation when the doctor changes to the instrument. In specific implementation, the moisture-absorbing plate 143 can be made of silicone and adhered to the outside of the connecting plate 142. The outer surface of the moisture-absorbing plate 143 can be covered with canvas, which has good moisture absorption capacity and easily evaporates sweat on the canvas quickly.

[0038] The width of the connecting plate 142 in this application is adapted to the width of the groove 137. The connecting plate 142 abuts against the guide plate to guide the movement of the connecting plate 142 through the guide plate fixedly disposed in the groove 137. In other embodiments, a guide groove may be provided in the side wall of the groove 137, and the end of the connecting plate 142 is slidably disposed in the guide groove, which can also achieve the technical effect of guiding the movement of the connecting plate 142.

[0039] Combination Figures 8-11In some embodiments, the adjusting assembly 140 further includes a guide sleeve 146 and a connecting rod 147. The guide sleeve 146 is connected to the inner side of the flow-limiting column 144, and the guide sleeve 146 is spaced within the corresponding air intake hole 134. The connecting rod 147 is connected to the bottom of the groove (inner wall of the drainage cavity) of the air intake hole 134. The connecting rod 147 and the guide sleeve 146 are inserted and connected. The elastic element 145 is a spring, which is sleeved on the guide sleeve 146 and the connecting rod 147 to guide the deformation of the elastic element 145. In a specific implementation, the guide sleeve 146, the flow-limiting column 144, and the connecting plate 142 are integrally formed. One end of the elastic element 145 is connected to the inner side of the flow-limiting column 144, and the other end is connected to the bottom of the groove (inner wall of the drainage cavity) of the drainage hole. The connecting rod 147 is also integrally formed with the anti-slip sleeve 132. During the process of adjusting component 140 switching from the first state to the second state, guide sleeve 146 moves toward connecting rod 147 and compresses elastic element 145, elastic element 145 deforms and stores force; and using the stored force of elastic element 145, adjusting component 140 switches from the second state to the first state.

[0040] Combination Figures 8-11 In some embodiments, the connecting rod 147 is movably disposed within the guide sleeve 146, while in other embodiments, the guide sleeve 146 is movably inserted into the connecting rod 147.

[0041] In summary, the urological rigid endoscope 10 provided in this application delivers airflow at a certain temperature via the fan 131, ensuring that the surgeon's hand temperature remains suitable even in low ambient temperatures, improving hand dexterity and preventing sluggishness during surgical procedures. The anti-slip component 130 reduces hand sweat, keeping the surgeon's hands dry and preventing slippage and instability during surgery caused by sweat between the hand and the anti-slip sleeve 132. While ensuring stable ventilation and sweat removal, the airflow deflector buffers the air, allowing for a wider and gentler airflow to the hand, further improving sweat removal efficiency.
