Description

Technical Field

[0001] The present invention relates to the technical field of nasopharyngoscopes, and particularly to a nasopharyngoscope for clinical radiotherapy of nasopharyngeal carcinoma. Background Art

[0002] Nasopharyngeal carcinoma is an epithelial malignant tumor originating from the mucosa of the nasopharynx, mainly occurring in the top wall and side walls of the nasopharynx, especially the pharyngeal recess. Nasopharyngeal carcinoma is a malignant tumor that requires high attention. By understanding its causes, symptoms, examination and diagnosis methods, as well as treatment and prevention measures, one can better protect their own health. For nasopharyngeal carcinoma, a nasopharyngoscope is usually inserted deeply into the oral cavity or nasal cavity, and then the nasal cavity and nasopharynx are observed in detail. It can help doctors observe the structure and lesions of the nasopharynx and is an important means for diagnosing various diseases of the nasal cavity and nasopharynx;

[0003] However, in actual use, we found that the existing nasopharyngoscopes need to be disinfected before use. The existing disinfection method is to first take out an alcohol spray bottle, then spray alcohol on the nasopharyngoscope for disinfection, and use tweezers to pick up a disinfected cotton ball to wipe the surface of the nasopharyngoscope. This method requires medical staff to repeatedly pick up medical instruments, and when wiping the nasopharyngoscope with the disinfected cotton ball, it is necessary to rotate the cotton ball or the nasopharyngoscope during the wiping process to ensure that the outside of the nasopharyngoscope can be wiped, thereby avoiding the occurrence of cross-infection. However, in actual use, we found that the existing method for disinfecting nasopharyngoscopes is too cumbersome and prone to omission of the disinfected area during the disinfection process. Therefore, we propose a nasopharyngoscope for clinical radiotherapy of nasopharyngeal carcinoma. Summary of the Invention

[0035] Embodiment 1: Please refer to Figure 1-8 , the present invention provides a technical solution: A nasopharyngoscope for clinical radiotherapy of nasopharyngeal carcinoma includes a nasopharyngoscope body 1 and a mirror tube 2 at one end thereof, and further includes

[0036] Two cleaning sponges 3 are provided, and both cleaning sponges 3 are slidably arranged on the outer side of the mirror tube 2. Both cleaning sponges 3 are arc-shaped, and both ends of the two cleaning sponges 3 are in mutual contact;

[0037] A plurality of spare sponges 4 are provided, and the plurality of spare sponges 4 are divided into two groups, and the two groups of spare sponges 4 are respectively located above and below the mirror tube 2;

[0038] An alcohol spraying component 5 is arranged on one side of the nasopharyngoscope body 1 close to the mirror tube 2. The alcohol spraying component 5 sprays disinfected alcohol on the two cleaning sponges 3, and drives the two cleaning sponges 3 to slide on the outer side of the mirror tube 2 to disinfect the outer side of the mirror tube 2;

[0039] The sponge replenishment component 6 is arranged outside the mirror tube 2. By using the sponge replenishment component 6 to drive the movement of multiple spare sponges 4, after the two cleaning sponges 3 are separated from the outside of the mirror tube 2, the multiple spare sponges 4 can automatically replenish on the outside of the mirror tube 2;

[0040] The cleaning component 7 is arranged outside the mirror tube 2. By using the cleaning component 7 to drive the two cleaning sponges 3 to slide on the surface of the mirror tube 2 after adsorbing alcohol, the two cleaning sponges 3 are driven to disinfect the surface of the mirror tube 2.

[0041] The alcohol spraying component 5 includes a storage part 8 arranged at one end of the nasopharyngoscope body 1 close to the mirror tube 2. The storage part 8 is used to store alcohol. A spraying part 9 is arranged outside the mirror tube 2. The spraying part 9 is used to spray alcohol. An extrusion part 10 is arranged outside the mirror tube 2. The extrusion part 10 is used to extrude the alcohol, and drive the alcohol to be sprayed onto the two cleaning sponges 3 through the spraying part 9.

[0042] The storage part 8 includes a storage bin 81 arranged at one end of the nasopharyngoscope body 1 close to the mirror tube 2. A storage tube 82 is arranged at the axis center of the storage bin 81, and the storage tube 82 is arranged outside the mirror tube 2. The connection between the storage bin 81 and the storage tube 82 is in a sealed state. A liquid injection tube 83 is arranged at the top of the storage bin 81. A storage cover 84 is arranged at the top of the liquid injection tube 83, and the liquid injection tube 83 is threadedly connected to the storage cover 84. When alcohol needs to be replenished, by rotating the storage cover 84, the storage cover 84 is separated from the liquid injection tube 83, and then alcohol can be injected by aligning with the liquid injection tube 83. The liquid injection tube 83 is located on the side of the extrusion plate 101 away from the control board 103, so that the alcohol entering the liquid injection tube 83 directly pours on the side of the extrusion plate 101 away from the control board 103. Its function is to facilitate medical staff to replenish alcohol and store alcohol.

[0043] The spraying part 9 includes a plurality of spraying tubes 91 arranged outside the storage tube 82. A spraying one-way valve 92 is arranged in each of the plurality of spraying tubes 91. The opening directions of the plurality of spraying one-way valves 92 all face the storage tube 82. A transmission groove 93 is formed in the storage tube 82. The plurality of spraying tubes 91 are all communicated with the transmission groove 93. A plurality of spraying grooves 94 are formed at the end of the storage tube 82 away from the nasopharyngoscope body 1, and the plurality of spraying grooves 94 are all communicated with the transmission groove 93. When the extrusion plate 101 slides in the storage bin 81, the spraying one-way valve 92 will be opened under the action of air pressure. Since the nasopharyngoscope body 1 is downward and the mirror tube 2 is upward at this time, the alcohol in the storage bin 81 will enter the spraying tubes 91 through the spraying one-way valve 92. When the alcohol enters the spraying tubes 91, the alcohol will enter the transmission groove 93 in the storage tube 82 along the spraying tubes 91 and be sprayed on the cleaning sponges 3 through the spraying grooves 94. Its function is to spray alcohol on the cleaning sponges 3, so that the cleaning sponges 3 can adsorb alcohol, and then can disinfect the mirror tube 2.

[0044] The extrusion member 10 includes an extrusion plate 101 slidably disposed in the storage bin 81. On the side of the extrusion plate 101 away from the nasopharyngoscope body 1, a plurality of extrusion rods 102 are provided. The plurality of extrusion rods 102 are all slidably disposed in the storage bin 81. The cavity between the side of the extrusion plate 101 close to the nasopharyngoscope body 1 and the storage bin 81 is used to store alcohol. At one end of the plurality of extrusion rods 102 away from the extrusion plate 101, a control plate 103 is provided. On the side of the extrusion plate 101 close to the control plate 103, an extrusion spring 104 is provided. One end of the extrusion spring 104 away from the extrusion plate 101 is disposed in the storage bin 81. An exhaust check valve 105 is disposed in the extrusion plate 101. The opening direction of the exhaust check valve 105 faces the nasopharyngoscope body 1. When the control plate 103 is extruded by the feeding bin 111, the control plate 103 will extrude the plurality of extrusion rods 102, so that when the plurality of extrusion rods 102 slide in the storage bin 81, they will continue to extrude the extrusion plate 101. When the extrusion plate 101 is extruded, the extrusion plate 101 will slide in the storage bin 81 towards the nasopharyngoscope body 1. At this time, the exhaust check valve 105 closes, so that the alcohol in the storage bin 81 enters the spray pipe 91. When the control plate 103 is disengaged from the extrusion of the feeding bin 111, the extrusion spring 104 will pull back the moved extrusion plate 101 and reset it. At this time, the exhaust check valve 105 opens, so that air reaches the side of the extrusion plate 101 away from the control plate 103 through the exhaust check valve 105, thereby completing the spraying of alcohol. Its function is to extrude the control plate 103 and utilize air pressure to make the alcohol in the storage bin 81 enter the spray pipe 91 and be discharged onto the cleaning sponge 3 through the spray pipe 91.

[0045] The sponge replenishment assembly 6 includes a feeding member 11 disposed outside the lens tube 2, which is used to drive the spare sponge 4 to automatically complete replenishment after the cleaning sponge 3 is separated from the lens tube 2. A feeding supplement member 12 is disposed outside the lens tube 2, which is used to supplement the spare sponge 4 after it is used up.

[0046] The feeding member 11 includes feeding bins 111 respectively arranged above and below the lens tube 2. Two groups of spare sponges 4 are respectively slidably arranged in the corresponding feeding bins 111. Discharge grooves 112 are formed on the opposite sides of the two feeding bins 111. The two discharge grooves 112 are respectively used in cooperation with the corresponding spare sponges 4. Discharge plates 113 used in cooperation with a plurality of spare sponges 4 are slidably arranged in the two feeding bins 111. First inclined plates 114 are slidably arranged on the opposite sides of the two discharge plates 113. The sides of the opposite ends of the two first inclined plates 114 close to the control board 103 are inclined surfaces. One end of the control board 103 away from the plurality of extrusion rods 102 is provided with a second inclined plate 115 used in cooperation with the two first inclined plates 114. The sides of the opposite ends of the two second inclined plates 115 away from the control board 103 are inclined surfaces. Auxiliary plates 116 are arranged on the sides of the two first inclined plates 114 away from the control board 103. Return springs 117 are arranged on the opposite sides of the two auxiliary plates 116. The ends of the two return springs 117 away from the two auxiliary plates 116 are arranged on the adjacent feeding bins 111;

[0047] Feeding plates 118 are slidably arranged in the two feeding bins 111. And the sides of the two groups of spare sponges 4 away from the control board 103 are attached to the corresponding feeding plates 118. A plurality of feeding springs 119 are arranged on the sides of the two feeding plates 118 away from the two groups of spare sponges 4. The ends of the plurality of feeding springs 119 away from the two feeding plates 118 are arranged in the feeding bins 111. During the process of the feeding bin 111 pressing on the control board 103, the first inclined plate 114 will contact the second inclined plate 115, and through their respective inclined surfaces, the first inclined plate 114 moves downward and slides in the corresponding feeding bin 111. When the first inclined plate 114 moves downward, the first inclined plate 114 will downwardly extrude the discharge plate 113, so that the discharge plate 113 moves downward together. When the discharge plate 113 moves downward under the action of the first inclined plate 114, a spare sponge 4 located below the discharge plate 113 will be downwardly extruded by the discharge plate 113, so that a spare sponge 4 located below the discharge plate 113 is extruded out of the feeding bin 111 through the discharge groove 112 and is stuck on the outer side of the lens tube 2;

[0048] After the first inclined plate 114 is separated from the extrusion of the second inclined plate 115, the return spring 117 arranged outside the feeding bin 111 will control the first inclined plate 114 to reset through the auxiliary plate 116, so that the first inclined plate 114 drives the discharge plate 113 to reset. At this time, the feeding spring 119 will control the feeding plate 118 to extrude the corresponding spare sponge 4, so that one of the plurality of spare sponges 4 reaches above or below the adjacent discharge plate 113, thereby preparing for the replacement of the next cleaning sponge 3. Its function is to automatically supplement the cleaning sponge 3, thereby reducing the workload of medical staff for frequently replacing the cleaning sponge 3.

[0049] The replenishing member 12 includes replenishing rods 121 respectively arranged on the sides of the two feeding plates 118 away from the control board 103. One end of the replenishing rod 121 away from the feeding plate 118 is provided with a replenishing handle 122. Replenishing shafts 123 are rotatably arranged on both of the two feeding bins 111. Replenishing covers 124 are rotatably arranged on the outer sides of the two replenishing shafts 123. One ends of the two replenishing covers 124 away from the two replenishing shafts 123 are both provided with a first magnet 125. Second magnets 126 which are used in cooperation with the two first magnets 125 are arranged in both of the two feeding bins 111.

[0050] The cleaning member 7 includes two connecting plates 71 arranged on the opposite sides of the two feeding bins 111. Driving plates 72 are arranged on the opposite sides of the two connecting plates 71. A plurality of anti-slip grooves 73 are formed in both of the two driving plates 72. Multi-stage telescopic plates 74 are arranged on the sides of the two feeding bins 111 close to the control board 103. One ends of the two multi-stage telescopic plates 74 away from the two feeding bins 111 are arranged on the control board 103. A baffle 75 is arranged on the opposite sides of the two feeding bins 111. When a medical staff member pinches the driving plate 72, the anti-slip grooves 73 formed in the driving plate 72 can increase the friction between the fingers of the medical staff member and the driving plate 72, avoiding the fingers slipping off the driving plate 72. When the driving plate 72 is pushed, the connecting plates 71 arranged on the opposite sides of the two driving plates 72 will move together with the driving plate 72. Then, the two feeding bins 111 are driven to move together through the two connecting plates 71. The baffle 75 on the opposite sides of the two feeding bins 111 will drive the cleaning sponge 3 to move together, so as to drive the cleaning sponge 3 adsorbed with alcohol to disinfect the outer side of the lens tube 2. The multi-stage telescopic plates 74 can, when the feeding bins 111 are moving, not only limit the moving track of the feeding bins 111, but also limit the distance of the feeding bins 111. Its function is to control the movement of the two feeding bins 111 through the driving plate 72, so as to drive the two cleaning sponges 3 adsorbed with alcohol to disinfect the outer side of the lens tube 2.

[0051] In use, when medical staff needs to disinfect the mirror tube 2 at one end of the nasopharyngoscope body 1, it is default that the cleaning sponge 3 has been sprayed with alcohol. One hand of the medical staff holds the nasopharyngoscope body 1, and the other hand pinches the two driving plates 72 and pushes the driving plates 72, so that the driving plates 72 move on the mirror tube 2 towards the end of the mirror tube 2 away from the nasopharyngoscope body 1. When the medical staff pinches the driving plates 72, the anti-slip grooves 73 formed on the driving plates 72 can increase the friction between the fingers of the medical staff and the driving plates 72, avoiding the fingers slipping off the driving plates 72. When the driving plates 72 are pushed, the connecting plates 71 arranged on the opposite sides of the two driving plates 72 will move together with the driving plates 72, and then drive the two feeding bins 111 to move together through the two connecting plates 71. The baffle plates 75 on the opposite sides of the two feeding bins 111 will drive the cleaning sponge 3 to move together, so as to drive the cleaning sponge 3 adsorbed with alcohol to disinfect the outer side of the mirror tube 2. The multi-stage telescopic plate 74 can, while the feeding bin 111 is moving, not only limit the moving track of the feeding bin 111, but also limit the distance of the feeding bin 111;

[0052] After the driving plate 72 drives the cleaning sponge 3 to move to the end of the mirror tube 2 away from the nasopharyngoscope body 1, turn the nasopharyngoscope body 1 so that the end of the mirror tube 2 away from the nasopharyngoscope body 1 faces downwards. Under the action of gravity, the cleaning sponge 3 will automatically separate from the mirror tube 2, thus completing the disinfection operation on the surface of the mirror tube 2. Then, control the two feeding bins 111 to reset through the driving plate 72, and the nasopharyngoscope body 1 and the mirror tube 2 can be used continuously;

[0053] When it is necessary to disinfect the mirror tube 2 again, turn the end of the mirror tube 2 away from the nasopharyngoscope body 1 upwards, and then control the two feeding bins 111 to squeeze towards the control board 103 through the driving plate 72 until the multi-stage telescopic plate 74 is squeezed to be completely retracted. At this time, the feeding bin 111 will directly press on the control board 103. During the process that the feeding bin 111 presses on the control board 103, the first inclined plate 114 will contact the second inclined plate 115, and through their respective inclined surfaces, the first inclined plate 114 will move downwards and slide in the corresponding feeding bin 111. When the first inclined plate 114 moves downwards, the first inclined plate 114 will press down on the discharge plate 113, causing the discharge plate 113 to move downwards together. When the discharge plate 113 moves downwards under the action of the first inclined plate 114, a spare sponge 4 located below the discharge plate 113 will be pressed down by the discharge plate 113, so that a spare sponge 4 located below the discharge plate 113 is extruded out of the feeding bin 111 through the discharge slot 112 and stuck on the outer side of the mirror tube 2. When the spare sponge 4 fits on the outer side of the mirror tube 2, the spare sponge 4 at this time becomes the new cleaning sponge 3;

[0054] When the spare sponge 4 located on the opposite sides of the two discharge plates 113 is squeezed to the outside of the mirror tube 2 and fits the outside of the mirror tube 2, the driving plate 72 continues to be pushed. At this time, the upper bin 111 will squeeze the control board 103. When the control board 103 is squeezed by the upper bin 111, the control board 103 will squeeze the multiple squeezing rods 102, so that the multiple squeezing rods 102 continue to squeeze the squeezing plate 101 when sliding in the storage bin 81. When the squeezing plate 101 is squeezed, the squeezing plate 101 will slide in the storage bin 81 toward the nasopharyngeal mirror body 1. At this time, the exhaust one-way valve 105 is closed, so that the alcohol in the storage bin 81 enters the spray tube 91;

[0055] When the extrusion plate 101 slides in the storage bin 81, the spray one-way valve 92 will be opened under the action of air pressure. Since the nasopharyngeal mirror body 1 is facing downward and the mirror tube 2 is facing upward at this time, the alcohol in the storage bin 81 will enter the spray tube 91 through the spray one-way valve 92. After the alcohol enters the spray tube 91, the alcohol will enter the transmission groove 93 in the storage tube 82 along the spray tube 91, and spray on the cleaning sponge 3 through the spray groove 94. When the control board 103 is separated from the extrusion of the upper bin 111, the extrusion spring 104 will pull the moved extrusion plate 101 back and reset it. At this time, the exhaust one-way valve 105 is opened, so that the air passes through the exhaust one-way valve 105 to reach the side of the extrusion plate 101 away from the control board 103, thereby completing the spraying of the alcohol;

[0056] After the inclined plate 114 is separated from the squeezing of the inclined plate 2 115, the reset spring 117 arranged on the outer side of the loading bin 111 will control the reset of the inclined plate 114 through the auxiliary plate 116, so that the inclined plate 114 drives the discharge plate 113 to reset. At this time, the loading spring 119 will control the loading plate 118 to squeeze the corresponding spare sponge 4, so that one of the multiple spare sponges 4 reaches above or below the adjacent discharge plate 113, thereby preparing for the next replacement of the cleaning sponge 3. After the cleaning sponge 3 absorbs alcohol, the cleaning sponge 3 can be controlled by the driving plate 72 to disinfect the outer side of the mirror tube 2.

[0057] When alcohol needs to be replenished, the storage cover 84 is rotated to separate the storage cover 84 from the injection tube 83, and then the alcohol is injected into the injection tube 83. The injection tube 83 is located on the side of the extrusion plate 101 away from the control board 103, so that the alcohol entering the injection tube 83 is directly poured onto the side of the extrusion plate 101 away from the control board 103;

[0058] When medical staff needs to replenish the spare sponge 4, rotate the feeding cover plate 124 to separate the magnet one 125 at one end of the feeding cover plate 124 from the corresponding magnet two 126, and then pull the feeding handle 122. When the feeding handle 122 moves, the feeding handle 122 will drive the feeding rod 121 on one side of it to move together, and the feeding rod 121 will drive the feeding plate 118 at one end of it to move, so that there is a feeding space in the feeding bin 111. Then, put the prepared spare sponge 4 into the feeding bin 111 and reset the feeding cover plate 124 so that the magnet one 125 at one end of it adsorbs to the corresponding magnet two 126.

[0059] Embodiment 2: Please refer to Figure 9 , Figure 10 , the present invention provides a technical solution: Fixed frames 13 are provided on both sides of the storage bin 81. Fixed shafts 14 are rotatably provided in the two fixed frames 13. Clamping plates 15 are provided on the outer sides of the two fixed shafts 14. Torsion springs 16 are provided at one ends of the two fixed shafts 14. One ends of the two torsion springs 16 away from the two fixed shafts 14 are provided on the corresponding fixed frames 13. Triangular plates 17 that cooperate with the two clamping plates 15 are provided on both sides of the nasopharyngoscope body 1. The storage tube 82 is slidably provided on the outer side of the mirror tube 2. The storage bin 81 is attached to the opposite end of the nasopharyngoscope body 1. When it is necessary to remove the storage bin 81, rotate the two clamping plates 15 to separate the two clamping plates 15 from the corresponding triangular plates 17, and then pull the storage bin 81. The storage tube 82 slides on the outer side of the mirror tube 2 until the storage bin 81 is separated from the mirror tube 2. When it is necessary to install the storage bin 81, directly align the mirror tube 2 with the axis of the storage tube 82, insert it directly, and make the storage tube 82 slide on the outer side of the mirror tube 2 until the clamping plate 15 contacts the triangular plate 17. At this time, the triangular plate 17 will push up the clamping plate 15. After the storage bin 81 is attached to the opposite end of the nasopharyngoscope body 1, the torsion spring 16 will control the fixed shaft 14 to reset, so that the clamping plate 15 on the outer side of the fixed shaft 14 is stuck on the triangular plate 17.
