Description

Technical Field

[0001] The present invention belongs to the technical field of medical appliances, and in particular relates to an auxiliary device for chemotherapy of esophageal cancer. Background Art

[0002] Esophageal cancer is one of the common malignant tumors of the digestive system. There are various treatment methods, among which chemotherapy is one of the important treatment methods and is widely used in clinical practice. However, after the traditional esophageal cancer chemotherapy device enters the esophagus, due to various factors such as external manipulation and the patient's own physiological activities, the catheter often shakes up and down. This not only increases the patient's discomfort, but may also affect the precise delivery of chemotherapy drugs, thereby affecting the treatment effect. Therefore, there is an urgent need for an auxiliary device that can be stably fixed in the esophagus and can at the same time heat the chemotherapy area to improve the treatment effect.

[0003] First, after entering the esophagus, traditional chemotherapy catheters often become displaced due to swallowing, esophageal peristalsis, or traction from external devices, and can even completely dislodge from the lesion. Clinical data show that in approximately 30% of cases, catheter misalignment prevents chemotherapy from reaching the target area, directly affecting the effectiveness of killing tumor cells. Furthermore, catheter movement can exacerbate mechanical friction on the esophageal mucosa, causing complications such as pain and bleeding, significantly reducing patient compliance with treatment.

[0004] Secondly, research has shown that controlling the temperature of the chemotherapy area within the range of 41-43°C can increase chemotherapy efficacy by 2-3 times by increasing tumor cell membrane permeability, inhibiting DNA repair mechanisms, and promoting intracellular drug accumulation. However, existing esophageal chemotherapy devices generally lack a precise temperature control module that is linked to drug release. Summary of the Invention

[0005] The purpose of the present invention is to provide an auxiliary device for chemotherapy of esophageal cancer. During chemotherapy, the device can be fixed in the patient's esophagus and the chemotherapy area can be sealed. It can also heat the lesion area to improve the penetration effect of the medicine.

Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0051] Please see the attached Figures 1 to 2 、 Figure 9 As shown, this embodiment provides an auxiliary device for esophageal cancer chemotherapy, comprising:

[0052] The main body 10 has a wire guide tube 13 fixedly connected to one side of the main body 10, a hollow motor 14 fixedly mounted on one end of the wire guide tube 13 away from the main body 10, and an additional tube 15 fixedly connected to the inner ring of the hollow motor 14;

[0053] The pipeline assembly 20 includes a slide plate 24, which is slidably connected to the wire guide tube 13. The side of the slide plate 24 away from the main body 10 is rotatably connected to a movable tube 26 through a rotary valve. The other end of the movable tube 26 is connected to a feed tube 27. Both the movable tube 26 and the feed tube 27 are slidably connected to the additional tube 15.

[0054] The fixing assembly 30 includes a sealing plate 31, which is slidably connected to the outer surface of the guide wire tube 13 and fixedly connected to the upper and lower ends of the slide plate 24. The outer surface of the sealing plate 31 and the outer surface of the additional tube 15 are both fixedly connected to the airbag 32;

[0055] The drive assembly 40 includes a drive plate 42, which is arranged on the side of the main body 10 away from the wire guide tube 13, and two sets of push rods 43 are fixedly connected to the side of the drive plate 42 close to the wire guide tube 13. The two sets of push rods 43 pass through the main body 10 and the wire guide tube 13 and are fixedly connected to the slide plate 24;

[0056] The spray assembly 50 includes a temperature control ring 51, which is fixedly connected to the lower end of the additional tube 15. A nozzle 52 is provided in the inner cavity of the temperature control ring 51. The upper end of the nozzle 52 is fixedly connected to a serrated plate 55. The serrated plate 55 is slidably connected to the inner cavity of the additional tube 15, and the upper end of the serrated plate 55 extends into the inner cavity of the additional tube 15 and contacts a toothed plate 56. The toothed plate 56 is fixedly connected to the lower end of the feed tube 27.

[0057] The hollow motor 14 drives the additional tube 15 to rotate, adjusts the direction of the nozzle 52, and the driving plate 42 drives the push rod 43 to move, so that the slide plate 24 and the sealing plate 31 move to control the distance between the two groups of air bags 32;

[0058] When the slide plate 24 moves, it drives the toothed plate 56 to move on the upper end of the serrated plate 55 to control the vibration of the nozzle 52.

[0059] It should be noted that to ensure the normal operation of the device, the main body 10 should have a built-in battery, and the battery should be connected to an external mains power supply. An external air pump and a liquid medicine delivery component are required. The battery is used to power the electrical components in the device, the air pump is used to ensure the normal expansion of the airbag 32, and the liquid medicine delivery component is used to deliver chemotherapy drugs to the applicator 52.

[0060] Both the serrated plate 55 and the toothed plate 56 are provided with two groups distributed on the front and rear sides of the upper end of the nozzle 52, in order to improve the stability of the vibration, and the upper end of the serrated plate 55 and the lower end of the toothed plate 56 are provided with toothed grooves, and the left and right sides of the lower end of the toothed plate 56 are provided with slopes and are rounded, in order to enable the toothed plate 56 to smoothly squeeze the serrated plate 55 to the bottom of the toothed plate 56 during the movement, and use the movement of the toothed grooves to generate vibration to clean the nozzle 52.

[0061] Preferably, in order to ensure that the toothed plate 56 can drive the serrated plate 55 to vibrate when it moves at the upper end of the serrated plate 55, it should be ensured that the height of the upper end of the serrated plate 55 is higher than the height of the lower end of the toothed plate 56 under normal conditions. In this embodiment, the height of the upper end of the serrated plate 55 is higher than the height of the lower end of the toothed plate 56 under normal conditions. The specific value is the height of a single group of toothed grooves, so that in the resetting process of the vibration process, the serrated plate 55 and the nozzle 52 can be reset to the initial state, thereby increasing the amplitude of vibration.

[0062] In this embodiment, during use, the guide wire tube 13 and the additional tube 15 are inserted into the patient's body, and then the hollow motor 14 drives the additional tube 15 to rotate, so that the nozzle 52 is aligned with the lesion area. At this time, the temperature control ring 51 is attached to the lesion and heats the lesion. During the heating process, the driving plate 42 drives the sealing plate 31 and the airbags 32 above it to move via the push rod 43 and the slide plate 24, adjusting the spacing between the two sets of airbags 32 so that they are located at the upper and lower ends of the lesion. At the same time, the slide plate 24 drives the feeding tube 27 and the toothed plate 56 to move, causing the serrated plate 55 and the nozzle 52 to vibrate for self-cleaning. After heating is completed, the two sets of airbags 32 are blown until they are full and attached to the inner wall of the esophagus. At this time, the chemotherapy liquid is transported to the nozzle 52 through the moving tube 26 and the feeding tube 27 for spraying chemotherapy.

[0063] Next, please refer to Figures 1 to 2 、 Figures 5 to 7 The lower end of the main body 10 is fixedly connected to a handle 11, the upper end of the main body 10 is mounted with a display 12, and the end of the additional tube 15 away from the main body 10 is fixedly mounted with a camera 16;

[0064] The additional tube 15 is provided with four sets of drainage grooves 17 on the outer edge of the camera 16, and the drainage grooves 17 are offset toward the main body 10 at one end toward the outside of the additional tube 15, so that when the liquid in the intestine covers the camera 16, the guide wire tube 13 can be pushed down to allow the liquid to flow out of the drainage grooves 17.

[0065] It should be noted that a damping shaft is provided at the bottom of the display 12 to facilitate adjustment of the orientation of the display 12 for easier viewing;

[0066] An electric slip ring (such as Figure 9 As shown), the camera 16 is powered by an electric slip ring, so that the additional tube 15 can power the camera 16 even when it is in a rotating state.

[0067] Preferably, in order to ensure that the camera 16 can operate normally, it should be ensured that the camera 16 can be connected wirelessly (such as WIFI, Bluetooth, Internet of Things) so that the images captured by the camera 16 can be transmitted to the display 12 for display.

[0068] In this embodiment, during operation, the precise location of the lesion is found through the camera 16 and the image is displayed through the display 12.

[0069] Next, please refer to Figures 1 to 2 、 Figure 4 and Figure 7 The pipeline assembly 20 includes a main pipe 21, which is fixedly connected to the inner cavity of the main body 10 and the guide wire tube 13, and also includes two groups of receiving heads 22. The front and rear sides of the main body 10 are respectively fixedly connected with the receiving heads 22, and the inlets of the two groups of receiving heads 22 extend out of the main body 10, and the outlets of the two groups of receiving heads 22 are connected to the main pipe 21. The end of the main pipe 21 away from the main body 10 is connected to a hose 23, and the other end of the hose 23 is fixedly connected to the middle of the slide 24. The connection of the hose 23 is used to prevent the slide 24 from being disconnected during the movement of the pipeline, thereby affecting the delivery of the liquid medicine. The end of the outer ring of the mobile pipe 26 away from the main body 10 is fixedly connected to a hexagonal block 28, and the hexagonal block 28 is slidably connected to the additional pipe 15, and the outer ring of the feeding pipe 27 is fixedly connected to a protective ring 29, which is slidably connected to the inner cavity of the additional pipe 15;

[0070] The upper and lower ends of the wire guide tube 13 are provided with strip grooves 25 at the position of the slide plate 24, and the strip grooves 25 pass through the wire guide tube 13. The upper and lower ends of the slide plate 24 are slidably connected in the strip grooves 25 and pass through the strip grooves 25 to be fixedly connected to the middle part of the inner circle of the sealing plate 31.

[0071] It should be noted that the two sets of receiving heads 22 are connected to the main pipe 21 through a Y-shaped pipe, so that different drugs can be mixed through the Y-shaped pipe, avoiding premature mixing of the drug solution for too long, resulting in degradation and affecting the chemotherapy effect;

[0072] The length of the hexagonal block 28 that can slide in the additional tube 15 is the same as the length of the strip groove 25. Therefore, no matter how the slide plate 24 slides, it cannot push the hexagonal block 28 out of the additional tube 15. In addition, the hexagonal block 28 can be used to limit the position of the hexagonal block 28 when the additional tube 15 rotates, driving the movable tube 26 and the feeding tube 27 to rotate together, thereby avoiding affecting the delivery of the drug.

[0073] The inlets of the two sets of receiving heads 22 are fixedly connected with anti-slip plugs, which are intended to facilitate the connection of the receiving heads 22 with external pipes;

[0074] The slide plate 24 is a long, medium-shaped plate that can only slide within the inner cavity of the guide wire tube 13 and cannot rotate, thereby avoiding affecting the delivery of the drug. A through groove is provided in the middle of the slide plate 24, and the two ends of the through groove are connected to the hose 23 and the mobile tube 26, respectively, so that the drug can flow from the hose 23 into the mobile tube 26 through the through groove in the middle of the slide plate 24.

[0075] The slide plate 24 is provided with a protective shell at the outer edge of the rotating valve connected to the hose 23 to improve the sealing effect;

[0076] The width of the sealing plate 31 is preferably more than three times the length of the strip groove 25, so that no matter where the sliding plate 24 drives the sealing plate 31 to move to the inner cavity of the strip groove 25, the sealing plate 31 is sufficient to cover the outer part of the strip groove 25, thereby preventing the liquid in the esophagus from entering the inner cavity of the guide wire tube 13 and causing damage to the internal components.

[0077] In this embodiment, during operation, the chemotherapy liquid enters the main pipe 21 through the receiving head 22 and is mixed. The liquid then passes through the hose 23 and the moving pipe 26 and enters the feeding pipe 27 until it is transferred to the nozzle 52 for chemotherapy operation.

[0078] Next, please refer to Figure 3 、 Figures 7 to 9The fixing assembly 30 also includes an air pipe 1 33, which is fixedly connected to the inner cavity of the push rod 43 and the slide 24 located above, and the end of the air pipe 1 33 away from the main body 10 passes through the slide 24 and the sealing plate 31, and is communicated with the air bag 32 on the sealing plate 31, and the end of the air pipe 1 33 close to the driving plate 42 passes through the push rod 43 and the driving plate 42, and extends out of the driving plate 42, and the inner cavity of the push rod 43 located below is fixedly connected with an air pipe 2 34, and the end of the air pipe 2 34 away from the main body 10 passes through the slide 24 and the moving tube 26, and passes through the feeding tube 27 and the additional tube 15, and is communicated with the air bag 32 fixed to the outer circle of the additional tube 15, and the other end of the air pipe 2 34 is the same as the air pipe 1 33, and both extend out of the driving plate 42;

[0079] The portion of the second trachea 34 between the slide 24 and the movable tube 26 is a spiral silicone tube that is coiled around the outer ring of the movable tube 26. This is designed to ensure that when the movable tube 26 rotates along with the additional tube 15, the second trachea 34 can only stretch along with the rotation and cannot fold, thereby avoiding affecting the operation of the airbag 32 connected to the second trachea 34.

[0080] It should be noted that both sets of airbags 32 are made of silicone. Under normal conditions, the inner cavities of both sets of airbags 32 are negative pressure and are attached to the surfaces of the guide wire tube 13 and the additional tube 15. After the airbags 32 are inflated, they can be attached to the inner wall of the esophagus to prevent the chemotherapy solution from affecting the rest of the normal esophagus.

[0081] In this embodiment, before chemotherapy is performed, the airbag 32 on the additional tube 15 is first moved to the bottom of the lesion, and then the driving plate 42 drives the slide plate 24 to move through the push rod 43, and the slide plate 24 drives the sealing plate 31 and the airbag 32 above to move until they are located above the lesion. Then, an external air pump is used to inflate the two groups of airbags 32 through trachea 1 33 and trachea 2 34, so that they expand until they are close to the inner wall of the esophagus. At this time, the two groups of airbags 32 completely seal the lesion area to prevent the chemotherapy solution from splashing onto the part of the esophagus outside the lesion and causing damage. At the same time, during the chemotherapy process, the two groups of airbags 32 can also stabilize the additional tube 15 to prevent it from shifting and shaking during operation, ensuring accurate chemotherapy effects.

[0082] Please refer again Figures 2 to 3 The drive assembly 40 also includes a limiting tube 41, which is fixedly connected to the end of the main body 10 away from the wire guide tube 13, and the driving plate 42 is slidably connected to the inner cavity of the limiting tube 41, and the middle part of the limiting tube 41 is rotatably connected to a screw rod 44 through a ball bearing. The end of the screw rod 44 close to the main body 10 passes through the limiting tube 41 and is rotatably connected to the main body 10 through a ball bearing, and the middle section outer ring of the screw rod 44 is threadedly connected to the middle part of the driving plate 42.

[0083] It should be noted that the portion of the screw rod 44 extending out of the outer end of the limiting tube 41 is provided with a rotating handle to facilitate driving the screw rod 44 to rotate;

[0084] Through slots are formed on both the upper and lower sides of the side of the limiting tube 41 away from the main body 10 , and the air pipe 1 33 and the air pipe 2 34 extend out of the limiting tube 41 through the through slots.

[0085] Preferably, in order to ensure that the two groups of airbags 32 can still be used normally after the spacing is adjusted, trachea 1 33 and trachea 2 34 are both slidably connected in the through groove of the limiting tube 41, and the parts of trachea 1 33 and trachea 2 34 extending out of the limiting tube 41 should be reserved with sufficient length and externally connected to an air pump so that the two groups of airbags 32 can be blown and expanded by the air pump, and the auxiliary driving plate 42 can slide through the reserved length to avoid affecting the adjustment of the spacing and the normal use of the airbags 32.

[0086] In this embodiment, when in use, the screw rod 44 is rotated to drive the driving plate 42 to slide in the limiting tube 41, thereby driving the slide plate 24 to move synchronously, adjusting the spacing of the airbags 32, and performing self-cleaning operations with the nozzle 52.

[0087] Please refer again Figures 11 to 15 The spray assembly 50 further includes two sets of elastic strips 53, which are respectively fixedly connected to the upper and lower ends of the nozzle 52, and the nozzle 52 is movably sleeved on the middle part of the outer ring of the additional tube 15. The two sets of elastic strips 53 are arranged at the upper and lower ends of the nozzle 52 in contact with the additional tube 15, and the upper end of the nozzle 52 is connected to the elastic tube 54, and the upper end of the elastic tube 54 is connected to the lower end of the feed tube 27;

[0088] The temperature control ring 51 is divided into three parts, namely the chip layer 511, the diffusion layer 512 and the silicone layer 513. The chip layer 511 is located on the innermost side of the additional tube 15. The side of the chip layer 511 facing the outside of the additional tube 15 is fixedly connected to the diffusion layer 512, and the outside of the diffusion layer 512 is fixedly connected to the silicone layer 513.

[0089] It should be noted that the chip layer 511 is a heating layer with a built-in TEC chip and FBG optical fiber, and the diffusion layer 512 is a heat-conducting layer with a built-in graphene thermal conductive material. The purpose is to allow the heat emitted by the chip layer 511 to diffuse through the diffusion layer 512 to the silicone layer 513, and then be transferred to the lesion area through the silicone layer 513, thereby increasing the temperature of the lesion area and thereby improving the effect of chemotherapy.

[0090] The elastic strips 53 are made of a highly elastic soft rubber material. When the nozzle 52 descends, its kinetic energy is absorbed by the lower elastic strip 53 , while the upper elastic strip 53 is stretched. When the nozzle 52 descends, the rebound of the two sets of elastic strips 53 drives the nozzle 52 upward, thus achieving vibration of the nozzle 52.

[0091] The elastic tube 54 is a soft and foldable silicone tube, so that the feeding tube 27 can still deliver liquid to the nozzle 52 through the elastic tube 54 during the movement.

[0092] Preferably, in order to ensure that the temperature of the chip layer 511 is sufficient to enhance the chemotherapy effect of the lesion area and does not cause excessive damage to the lesion area, the heating temperature of the chip layer 511 should be maintained at 43 to 45 degrees Celsius, so that the heat can be diffused and transferred to heat the lesion area to 41 to 43 degrees Celsius, thereby improving the effect of chemotherapy.

[0093] In this embodiment, when the slide 24 moves, it drives the movable tube 26 and the feed tube 27 to move synchronously. The feed tube 27 then drives the toothed plate 56 to slide on the upper end of the serrated plate 55. The toothed grooves of the toothed plate 56 and the serrated plate 55 cooperate to cause the spray head 52 to vibrate. During vibration, the spray head 52 can utilize the elastic strip 53 to achieve rapid reciprocating vibration, reducing damage to the spray head 52. This helps prevent the chemotherapy drug from condensing on the spray head 52 and ensures that the chemotherapy drug is evenly sprayed on the lesion area. The chemotherapy liquid then enters the elastic tube 54 and the spray head 52 through the feed tube 27 and is sprayed from the spray head 52 for chemotherapy. In addition, before chemotherapy is performed, the temperature control ring 51 can be driven to operate, and the heat generated by the chip layer 511 is transferred to the silicone layer 513 via the diffusion layer 512, thereby heating the lesion area and improving the permeability and efficacy of the chemotherapy drug.

[0094] The working principle of the present invention is as follows: the guide wire tube 13 and the additional tube 15 are inserted into the patient's body, and the airbag 32 on the additional tube 15 is moved to the bottom of the lesion. Then, the hollow motor 14 drives the additional tube 15 to rotate, so that the nozzle 52 is aligned with the lesion area. At this time, the temperature control ring 51 is attached to the lesion, and the chip layer 511 generates heat, which is transferred to the silicone layer 513 via the diffusion layer 512 to heat the lesion area. During the heating process, the screw rod 44 is rotated to drive the driving plate 42 to slide in the limiting tube 41, thereby driving the slide plate 24 to move synchronously. The slide plate 24 drives the sealing plate 31 and the airbag 32 above to move until they are above the lesion. At this time, the slide plate 24 also drives the moving tube 26 and the feeding tube 27 to move synchronously. The feeding tube 27 drives the toothed plate 56 to slide on the upper end of the serrated plate 55. The toothed grooves of the toothed plate 56 and the serrated plate 55 cooperate to cause the nozzle 52 to vibrate, causing the nozzle 52 to self-clean. After heating is complete, an external air pump inflates the two balloons 32 through trachea 1 33 and trachea 2 34, expanding them until they cling tightly to the inner wall of the esophagus, completely sealing the affected area. The chemotherapy liquid then enters the main tube 21 through the receiving head 22 and undergoes mixing. The liquid then flows through the flexible tube 23 and the mobile tube 26, through the feed tube 27, and finally into the elastic tube 54 and the spray head 52, where it is sprayed for chemotherapy.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
