Description

Technical Field

[0001] The invention belongs to the technical field of thoracoscope lens cleaning, in particular to a thoracoscope lens cleaning device. Background Art

[0002] During thoracoscopic surgery, due to the difference between the room temperature (20-24°C) in the operating room and the temperature in the chest cavity (37°C), when the laparoscope enters the chest cavity, water vapor easily condenses on the lens and fogs up, reducing the clarity of the surgical field and affecting the surgical operation. In addition, although the space between the collapsed lung tissue and the thorax provides operating space for minimally invasive surgery under single-lung ventilation, it is still inevitable that smoke, fat droplets, blood, etc. will contaminate the thoracoscopic lens.

[0003] The Chinese invention patent publication number CN118557128A discloses a thoracoscopic and laparoscopic lens cleaning device, comprising: a cleaning barrel, a cleaning assembly is provided in the cleaning barrel, and the opening of the cleaning barrel is upward; a drying barrel, the drying barrel is located on the outside of the cleaning barrel, the opening of the drying barrel is downward, and the drying barrel is connected to the drying assembly; a partition, the partition is used to seal the opening of the drying barrel and the opening of the cleaning barrel. The beneficial effects of the invention: through the setting of the drying barrel and the cleaning barrel, when it is necessary to clean the thoracoscopic and laparoscopic lens, only the drying tube needs to be moved to complete the two functions of cleaning and heating, so that the lens can be cleaned and prevented from fogging, ensuring that the lens is clean and clear, reducing the work pressure of the doctor holding the mirror, ensuring the continuity of the surgeon's surgical ideas and operations, and improving the work efficiency of the surgical team.

[0004] However, the above-mentioned technologies often have the following defects: medical staff are required to constantly stop the operation during the operation, remove the lens outside the chest cavity for cleaning, and then put the cleaned lens back into the chest cavity to continue the operation.

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Example 1: As Figures 1 to 10 shown, a thoracoscope lens cleaning device according to the present invention includes a rinser 1. A plug 2 is inserted into the front side of the rinser 1. A data cable 3 is fixedly installed at the front end of the plug 2. A first infusion tube 4 is fixedly installed on the front side of the rinser 1. The data cable 3 and the first infusion tube 4 are arranged side by side. The opposite ends of the data cable 3 and the first infusion tube 4 connected to the plug 2 are fixedly installed on a puncture device main body 5. A puncture cylinder 6 is installed at the lower end of the puncture device main body 5 through a thread. A protective cover 7 is installed at the upper end of the puncture device main body 5 through a thread. A through hole 8 is opened on the protective cover 7. A first control button 45 is fixedly installed at the grip of the puncture device main body 5. A second control button 46 is fixedly installed at the grip of the puncture device main body 5. The first control button 45 and the second control button 46 are arranged in parallel. A wiping assembly for cleaning the thoracoscope lens is arranged in the puncture device main body 5. The cleaning mixture prepared in the rinser 1 is delivered to the wiping assembly through the first infusion tube 4; an adjusting assembly for adjusting the position of the thoracoscope lens in the puncture device main body 5 and the puncture cylinder 6 is arranged in the puncture device main body 5.

[0036] In actual use, the thoracoscope body is inserted into the puncture device main body 5 and the puncture cylinder 6 through the through hole on the protective cover, and the position of the thoracoscope body in the puncture device main body 5 and the puncture cylinder 6 is adjusted through the adjusting assembly. If the thoracoscope lens needs to be wiped and cleaned comprehensively, at this time, the thoracoscope body is adjusted through the adjusting assembly until the thoracoscope lens is at the position of the wiping assembly, and the wiping assembly is unfolded and closely attached to the surface of the thoracoscope lens, thereby realizing the comprehensive wiping and cleaning of the thoracoscope lens. In addition, the setting of the adjusting assembly enables medical staff to adjust the position of the thoracoscope lens in the puncture device main body 5 and the puncture cylinder 6 according to actual needs, further improving the cleaning efficiency and convenience. Moreover, the cleaning mixture prepared in the rinser 1 is delivered to the wiping assembly through the first infusion tube 4 to wash the thoracoscope lens, ensuring the cleanliness of the thoracoscope lens wiping;

[0037] Of course, in order to ensure that the cleaning mixture prepared in the rinser 1 can be delivered to the wiping assembly through the first infusion tube 4, an internal rinsing pump structure is arranged in the rinser to deliver the cleaning mixture to the wiping assembly through the first infusion tube 4, and the cleaning mixture is composed of existing surfactants, dry carbon dioxide and saline, or the cleaning mixture is such as glass cleaner, etc.

[0038] As Figures 3 to 5As shown, a guide cylinder 9 is movably inserted into the trocar body 5. A slot 12 is formed in the inner wall at the rear side of the guide cylinder 9. A sealing ring 13 is sleeved at the lower end of the guide cylinder 9, and the outer wall of the sealing ring 13 is attached to the inner wall at the lower end of the trocar cylinder 6.

[0039] According to the fact that the outer wall of the sealing ring 13 is attached to the inner wall at the lower end of the trocar cylinder 6, it can effectively prevent the liquid or stain generated during the wiping process from flowing into the space between the trocar cylinder 6 and the guide cylinder 9, ensuring the cleanliness and service life of the device.

[0040] As Figures 6 to 10 shown, the wiping assembly includes a fixing ring 10 which is fixedly installed on the inner wall of the trocar body 5. A plug rod 11 is fixedly installed at the lower right side of the fixing ring 10. The lower end of the plug rod 11 is movably inserted into the slot 12. A receiving groove 14 is formed in the lower end of the plug rod 11. A flap 15 is rotatably installed in the receiving groove 14. A spraying head 16 is fixedly installed at the lower left side of the flap 15. A cavity 17 is arranged in the spraying head 16. A plurality of groups of spray nozzles 18 are annularly formed on the spraying head 16 at the front side of the cavity 17. A second infusion tube 19 is fixedly installed in the plug rod 11. The lower end of the second infusion tube 19 communicates with the cavity 17 in the spraying head 16. The upper end of the second infusion tube 19 is communicated with the first infusion tube 4 through the trocar body 5. A driving assembly for controlling the unfolding of the flap 15 and the spraying head 16 is arranged in the fixing ring 10 and the plug rod 11.

[0041] When it is necessary to wipe the thoracoscope lens, the driving assembly drives the flap 15 and the spraying head 16 to unfold, so that the scraping plate 22 is attached to the thoracoscope lens. The surface of the spraying head 16 is attached to the thoracoscope lens, so that there is a small gap between the spraying head 16 and the thoracoscope lens. The cleaning mixture prepared in the rinser 1 is conveyed into the cavity 17 and sprayed out through the plurality of groups of spray nozzles 18, and the cleaning mixture is evenly sprayed on the surface of the thoracoscope lens, thereby wiping the lens and realizing the comprehensive cleaning of the thoracoscope lens.

[0042] As Figures 6 to 10 shown, a first driving motor 20 is fixedly installed at the connection between the lower end of the flap 15 and the spraying head 16. The output shaft of the first driving motor 20 is fixedly installed with a rotating plate 21, and a scraping plate 22 is fixedly installed on the rotating plate 21.

[0043] When the wiping assembly works, the scraping plate 22 is closely attached to the surface of the thoracoscope lens, and the scraping plate 22 rotates as the first driving motor 20 and the rotating plate 21 rotate, effectively removing stains and fog and keeping the lens clear.

[0044] As Figures 9 to 10As shown in the figure, the driving assembly includes a second driving motor 23, which is fixedly installed inside the right end of the fixed ring 10. The output shaft of the second driving motor 23 is fixedly installed with a reduction motor 24. A toothed ring 26 is rotatably installed inside the fixed ring 10. A driving gear 25 is rotatably installed inside the right end of the fixed ring 10. The driving gear 25 is fixedly connected to the driving shaft of the reduction motor 24. The driving gear 25 meshes with the teeth on the upper side of the toothed ring 26. A plurality of driven gears 27 are annularly arranged and installed inside the fixed ring 10. A first sleeve 28 is coaxially and fixedly installed under the driven gear 27 at the right end of the fixed ring 10. A pull rod 29 is inserted into the lower end of the first sleeve 28 through a thread. The lower end of the pull rod 29 is rotatably installed with a connecting rod 30. The right end of the connecting rod 30 is hinged to the upper left side of the flap 15.

[0045] When the driving assembly starts to work, the driving shafts of the second driving motor 23 and the reduction motor 24 drive the driving gear 25 to rotate synchronously. Since the driving gear 25 meshes with the teeth of the toothed ring 26, the toothed ring 26 will rotate in the opposite direction as the driving gear 25 rotates, thereby driving the driven gear 27 and the first sleeve 28 to rotate. The rotating first sleeve 28 drives the pull rod 29 inserted through the thread to move up and down, and then pulls the connecting rod 30 rotatably installed at the lower end of the pull rod 29 to move up and down, which can ensure that it slides up and down when the driving assembly works, providing a stable support point for the unfolding of the flap 15 and the spray head 16, so as to realize the control of the unfolding and reset of the flap 15 and the spray head 16 in the wiping assembly, enabling the wiping assembly to unfold and close smoothly, thereby ensuring the uniformity and stability of the wiping of the thoracoscope lens by the wiping assembly.

[0046] As Figures 5 to 6 shown in the figure, the left side surface of the scraper 22 is wrapped with a silica gel material, and a water-proof coating is provided on the silica gel surface of the left side surface of the scraper 22.

[0047] The wrapping of the silica gel material has excellent wear resistance, corrosion resistance and high-temperature stability, which can effectively extend the service life of the scraper 22, prevent scratches on the thoracoscope lens during wiping, and maintain its good wiping effect. The setting of the water-proof coating can prevent penetration into the inside of the scraper 22 during the wiping process, avoiding material expansion or deformation caused by moisture, and further ensuring the stability and wiping effect of the wiping assembly.

[0048] As Figures 7 to 9As shown in the figure, the adjusting assembly includes a second sleeve 31. A plurality of groups of second sleeves 31 are fixedly installed on the upper sides of a plurality of groups of driven gears 27. A first adjusting screw 32 is inserted into each of the plurality of groups of second sleeves 31 through threads. The upper ends of the plurality of first adjusting screws 32 are fixedly installed with a limit ring 33. The limit ring 33 is attached to the upper side of the fixed ring 10. Activity grooves 34 are symmetrically formed in the left and right ends of the limit ring 33. A return spring 35 is installed in each of the two activity grooves 34. A slider 36 is slidably installed in one end of each of the two activity grooves 34 facing each other. Grooves 37 are formed in the left and right sides of the two sliders 36. A roller 38 is rotatably installed in each of the two grooves 37. Clamping assemblies for limiting and fixing the thoracoscope body are arranged on the front and rear sides of the two sliders 36.

[0049] By rotating the plurality of groups of driven gears 27 and the plurality of groups of second sleeves 31, the plurality of groups of first adjusting screws 32 and the limit ring 33 can be driven to move up and down, making the adjustment process smoother, avoiding damage to the thoracoscope lens caused by improper adjustment. When the thoracoscope body is inserted through the puncture cylinder 6 and the guiding cylinder 9 in the limit ring 33, the clamping assembly can limit and fix the thoracoscope body to ensure that it does not shake during the wiping process, further improving the stability and effect of cleaning.

[0050] When the second sleeve 31 rotates, the first adjusting screw 32 inserted into the second sleeve 31 slides out or slides in according to the threads. When the first sleeve 28 rotates, the pull rod 29 slides out of or slides into the first sleeve 28 through the threads. The first sleeve 28 and the second sleeve 31 are two components connected to the driven gear 27 inside the right end of 10. The up and down movement of the limit ring 33 can drive the thoracoscope to be adjusted, and the flap 15 and the spraying head 16 are opened or reset. Thus, when the thoracoscope lens moves upward, the flap 15 and the spraying head 16 can be unfolded for flushing.

[0051] As Figures 7 to 8 shown in the figure, the clamping assembly includes two groups of driving bevel gears 40. The two groups of driving bevel gears 40 are symmetrically installed on the front and rear ends of the roller 38. Driven bevel gears 41 are installed in the front and rear ends of the slider 36. The two driven bevel gears 41 installed in the slider 36 are rotatable structures. The two driven bevel gears 41 are meshed with the two groups of driving bevel gears 40. Second adjusting screws 42 are inserted into the two driven bevel gears 41 through threads. The diameters of the two second adjusting screws 42 are smaller than the diameters of the two driven bevel gears 41. Sliding rods 43 are fixedly installed at one ends of the two second adjusting screws 42 close to the inner wall of the limit ring 33. Clamping plates 44 are fixedly installed on the two sliding rods 43.

[0052] When the thoracoscope body is inserted through the puncture cylinder 6 and the guiding cylinder 9 from within the limit ring 33, the thoracoscope body is in contact with the roller 38, thereby driving the roller 38 to rotate. When the roller 38 rotates, it drives the two sets of driving bevel gears 40 and the two sets of driven bevel gears 41 to rotate on the slider 36. As a result, the two sets of second adjusting screws 42 and the sliding rod 43 move on the slider 36, causing the two sets of clamping plates 44 to clamp and fix the thoracoscope body, and adapting to thoracoscope bodies of different sizes, enabling the device to better adapt to thoracoscopes of different sizes, improving the applicability and practicality of the device. Moreover, the surface of the roller 38 is provided with a rubber layer that increases friction, so that when the roller 38 is in contact with the thoracoscope, it has a relatively large friction coefficient.

[0053] As Figures 7 to 8 shown, bearings 39 are sleeved on the front and rear ends of the two sets of rollers 38, and the bearings 39 at the front and rear ends of the two sets of rollers 38 are in contact with the connections between the front and rear ends of the two sets of rollers 38 and the two sets of sliders 36.

[0054] Through the setting of the bearings 39, not only is the stability of the roller 38 during rotation enhanced, but also wear caused by long-term use is avoided, extending the service life of the device.

[0055] As Figures 7 to 8 shown, anti-slip pads are glued to the opposite sides of the four sets of clamping plates 44 on the left and right. The opposite sides of the four sets of clamping plates 44 on the left and right are all arc-shaped, and the arc surfaces on the opposite sides of the four sets of clamping plates 44 on the left and right have the same radian as the inner wall of the limit ring 33.

[0056] During the process of the clamping assembly clamping and fixing the thoracoscope body, through the setting of the anti-slip pads, the friction between the clamping plates 44 and the thoracoscope body can be increased, preventing the thoracoscope body from sliding or shaking during the wiping process, further improving the stability of the thoracoscope body during the cleaning process. At the same time, the opposite sides of the four sets of clamping plates 44 on the left and right are all arc-shaped, and the arc surfaces have the same radian as the inner wall of the limit ring 33. Such a design can not only better adapt to the shape of the thoracoscope body, but also ensure that the pressure exerted by the clamping assembly on the thoracoscope body during clamping is evenly distributed, avoiding damage to the thoracoscope body caused by uneven pressure. In addition, the material of the anti-slip pads is soft and wear-resistant, which can protect the thoracoscope body while extending the service life of the clamping assembly.

[0057] Working principle: When in use, first insert the thoracoscope body through the through hole 8 on the protective cover 7, and then completely insert the thoracoscope body into the puncture device main body 5 and the puncture cylinder 6. At this time, the thoracoscope body will be in contact with the two groups of rollers 38 in the limit ring 33. As the thoracoscope body continues to be inserted, the rollers 38 will rotate under the thrust of the thoracoscope body. At the same time, the rotation of the two groups of rollers 38 will drive the two groups of driving bevel gears 40 installed at the front and rear ends to rotate synchronously. Since the four groups of driving bevel gears 40 are engaged with the four groups of driven bevel gears 41, the four groups of driven bevel gears 41 will also rotate with the rotation of the four groups of driving bevel gears 40. Then, the rotation of the four groups of driven bevel gears 41 will drive the second adjustment screw 42 inserted therein through the thread to move. Since a sliding rod 43 is fixedly installed at one end of the second adjustment screw 42 close to the inner wall of the limit ring 33, the movement of the four groups of second adjustment screws 42 will drive the four groups of sliding rods 43 and the four groups of clamping plates 44 to move together. As the four groups of clamping plates 44 move, the four groups of clamping plates 44 will gradually approach the thoracoscope body and finally clamp and fix the thoracoscope body. When it is necessary to wipe the thoracoscope lens, the drive shafts of the second drive motor 23 and the reduction motor 24 drive the driving gear 25 to rotate. As the driving gear 25 rotates, it drives the toothed ring 26, and the rotation of the toothed ring 26 drives the multiple groups of driven gears 27, the first sleeve 28, and the multiple groups of second sleeves 31 to rotate synchronously. As the first sleeve 28 rotates, the pull rod 29 slides upward, so that the pull rod 29 drives the flap 15 and the spray head 16 to unfold through the connecting rod 30. And when the multiple groups of second sleeves 31 rotate, they slide the multiple groups of first adjustment screws 32 and the limit ring 33 upward, thereby adjusting the position of the thoracoscope body clamped in the limit ring 33 upward, so that the scraper 22 on the spray head 16 is in close contact with the surface of the thoracoscope lens. At this time, the cleaning mixture prepared in the rinser 1 will be transported to the spray head 16 through the first infusion tube 4, the cavity 17, the multiple spray ports 18, and the second infusion tube 19 and evenly sprayed on the surface of the thoracoscope lens. Subsequently, the scraper 22 will rotate with the rotation of the first drive motor 20 and the rotating plate 21, so as to effectively remove stains from the thoracoscope lens and keep the lens clear.
