Description

Technical Field

[0001] The 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 them, chemotherapy is one of the important treatment methods and is widely used in clinical practice. However, after entering the esophagus, the traditional esophageal cancer chemotherapy device often causes the catheter to shake up and down due to various factors such as external manipulation and the patient's own physiological activities. 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 heat the chemotherapy area to improve the treatment effect.

[0003] First, after the traditional chemotherapy catheter enters the esophagus, it is often displaced due to the patient's swallowing action, esophageal peristalsis or external equipment traction, or even completely out of the lesion area. Clinical data show that in about 30% of cases, chemotherapy drugs do not cover the target area due to catheter deviation, which directly affects the efficiency of killing tumor cells. In addition, catheter shaking will aggravate the mechanical friction of the esophageal mucosa, causing complications such as pain and bleeding, and significantly reducing patient treatment compliance.

[0004] Secondly, studies have shown that controlling the temperature of the chemotherapy area within the range of 41-43°C can increase the efficacy of chemotherapy by 2-3 times by increasing the permeability of tumor cell membranes, inhibiting DNA repair mechanisms, and promoting drug accumulation in cells. However, existing esophageal chemotherapy devices generally lack precise temperature control modules that are linked to drug release. Summary of the invention

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

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

[0052] A main body 10, a wire guide tube 13 is fixedly connected to one side of the main body 10, a hollow motor 14 is fixedly installed on one end of the wire guide tube 13 away from the main body 10, and an additional tube 15 is 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 in the wire guide tube 13. The side of the slide plate 24 away from the main body 10 is rotatably connected to a moving tube 26 through a rotating valve. The other end of the moving tube 26 is connected to a feeding tube 27. Both the moving tube 26 and the feeding tube 27 are slidably connected in 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 the sealing plate 31 is fixedly connected to the upper and lower ends of the slide plate 24, and the outer surface of the sealing plate 31 and the outer surface of the additional tube 15 are fixedly connected with an air bag 32;

[0055] A driving assembly 40, the driving assembly 40 includes a driving plate 42, the driving plate 42 is arranged on a side of the main body 10 away from the wire guide tube 13, and two groups of push rods 43 are fixedly connected to the side of the driving plate 42 close to the wire guide tube 13, and the two groups of push rods 43 both penetrate the main body 10 and the wire guide tube 13 and are fixedly connected to the slide plate 24;

[0056] The medicine spraying 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 arranged in the inner cavity of the temperature control ring 51. A sawtooth plate 55 is fixedly connected to the upper end of the nozzle 52. The sawtooth plate 55 is slidably connected to the inner cavity of the additional tube 15. The upper end of the sawtooth 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 feeding 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, and controls 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 sawtooth plate 55 to control the vibration of the nozzle 52.

[0059] It should be noted that, in order 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 the mains electricity, and an air pump and a liquid medicine delivery component should be connected to the mains electricity, so as to use the battery to power the electrical components in the device, use the air pump to make the airbag 32 expand normally, and use the liquid medicine delivery component to deliver chemotherapy drugs to the nozzle 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 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 utilize 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 sawtooth plate 55 to vibrate when it moves at the upper end of the sawtooth plate 55, it should be ensured that the height of the upper end of the sawtooth 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 sawtooth 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 sawtooth plate 55 and the nozzle 52 can be reset to the initial state to increase the amplitude of vibration.

[0062] In this embodiment, when in 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 aimed at the lesion area, and the temperature control ring 51 is attached to the lesion to heat the lesion. During the heating process, the driving plate 42 drives the sealing plate 31 and the airbag 32 above it to move through the push rod 43 and the slide plate 24, and adjusts the spacing between the two groups 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, so that the sawtooth plate 55 and the nozzle 52 vibrate for self-cleaning. After the heating is completed, the two groups of airbags 32 are blown to fullness until they are 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 Figure 1 to Figure 2 , Figures 5 to 7 A handle 11 is fixedly connected to the lower end of the main body 10, a display 12 is installed on the upper end of the main body 10, and a camera 16 is fixedly installed on one end of the additional tube 15 away from the main body 10;

[0064] The additional tube 15 is provided with four sets of drainage grooves 17 at 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 make the liquid 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 easy viewing;

[0066] An electric slip ring (such as Fig. 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 Figure 1 to Figure 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 wire guide 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 with the main pipe 21. The end of the main pipe 21 away from the main body 10 is connected with 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 circle of the moving pipe 26 away from the main body 10 is fixedly connected with a hexagonal block 28, and the hexagonal block 28 is slidably connected in the additional pipe 15, and the outer circle of the feeding pipe 27 is fixedly connected with a protective ring 29, and the protective ring 29 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 groove 25 passes through the wire guide tube 13. The upper and lower ends of the slide plate 24 are slidably connected in the strip groove 25, and pass through the strip groove 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 receiving heads 22 are connected to the main pipe 21 through a Y-shaped pipeline, enabling different drugs to be mixed through the Y-shaped pipeline, avoiding premature and excessive mixing of the liquid medicine, resulting in degradation and affecting the chemotherapy effect;

[0072] The length space in which the hexagonal block 28 can slide in the additional pipe 15 is the same as the length of the strip-shaped groove 25, so that no matter how the sliding plate 24 slides, it cannot push the hexagonal block 28 out of the additional pipe 15. When the additional pipe 15 rotates, the hexagonal block 28 can be used for limiting, driving the moving pipe 26 and the feeding pipe 27 to rotate together, avoiding affecting the drug delivery;

[0073] Anti-slip plugs are fixedly connected to the positions of the inlets of the two receiving heads 22, aiming to facilitate the connection between the receiving heads 22 and external pipelines;

[0074] The sliding plate 24 is a long plate in the shape of a Chinese character "zhong", so that the sliding plate 24 can only slide in the inner cavity of the guide wire tube 13 and cannot rotate, avoiding affecting the drug delivery. A through groove is opened in the middle of the sliding plate 24, and the two ends of the through groove are respectively communicated with the flexible tube 23 and the moving tube 26, aiming to enable the drug to flow from the flexible tube 23 into the moving tube 26 through the through groove in the middle of the sliding plate 24;

[0075] A protective shell is arranged at the position of the outer edge of the rotary valve where the sliding plate 24 is connected to the flexible tube 23, aiming to improve the sealing effect;

[0076] The width of the sealing plate 31 is preferably more than three times the length of the strip-shaped groove 25, aiming to ensure that no matter where the sliding plate 24 drives the sealing plate 31 to move into the inner cavity of the strip-shaped groove 25, the sealing plate 31 is sufficient to cover a part outside the strip-shaped groove 25, avoiding the liquid in the esophagus from entering the inner cavity of the guide wire tube 13 and damaging 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. Subsequently, the liquid enters the feeding pipe 27 through the flexible tube 23 and the moving tube 26, and finally enters the spray head 52 for chemotherapy operation.

[0078] Secondly, please refer to again Figure 3 、 Figures 7 to 9The fixing assembly 30 further includes an air pipe 1 33, which is fixedly connected to the inner cavity of the push rod 43 and the slide plate 24 located above, and the end of the air pipe 1 33 away from the main body 10 penetrates the slide plate 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 penetrates 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 penetrates the slide plate 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 on 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 air pipe 2 34 between the slide plate 24 and the moving tube 26 is a spiral silicone tube, which is coiled around the outer ring of the moving tube 26, so that when the moving tube 26 rotates with the additional tube 15, the air pipe 2 34 can only stretch along with the rotation and cannot be folded, thereby avoiding affecting the operation of the airbag 32 connected to the air pipe 2 34.

[0080] It should be noted that both groups of airbags 32 are made of silicone. Under normal conditions, the inner cavities of both groups 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 upper airbag 32 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 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, thereby ensuring accurate chemotherapy effects.

[0082] Please refer again Figures 2 to 3 The driving assembly 40 also includes a limiting tube 41, which is fixedly connected to one end of the main body 10 away from the wire guide tube 13, and a driving plate 42 is slidably connected to the inner cavity of the limiting tube 41. The middle part of the limiting tube 41 is rotatably connected to a screw rod 44 through a ball bearing. One 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 of the 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] The limiting tube 41 is provided with through grooves on both the upper and lower sides of the side 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 grooves.

[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 inflated by the air pump, and the reserved length can be used to assist the driving plate 42 to slide, so as 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 causing the nozzle 52 to perform a self-cleaning operation.

[0087] Please refer again Figures 11 to 15 The spraying assembly 50 further includes two sets of elastic strips 53, which are respectively fixedly connected to the upper and lower ends of the spray head 52, and the spray head 52 is movably sleeved in the middle 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 spray head 52 that contact the additional tube 15, and the upper end of the spray head 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 feeding tube 27;

[0088] The temperature control ring 51 is divided into three parts, namely a chip layer 511, a diffusion layer 512 and a silicone layer 513, wherein the chip layer 511 is located at the innermost side of the additional tube 15, the chip layer 511 is fixedly connected to the diffusion layer 512 on one side facing the outer side of the additional tube 15, and the outer side 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 heat-conducting material, which is intended to allow the heat emitted by the chip layer 511 to diffuse to the silicone layer 513 through the diffusion layer 512, and then be transferred to the lesion area through the silicone layer 513, thereby increasing the temperature of the lesion area and thus improving the effect of chemotherapy;

[0090] The elastic strip 53 is made of a highly elastic soft rubber material, so that the kinetic energy of the nozzle 52 when it descends will be absorbed by the elastic strip 53 below, while stretching the elastic strip 53 above. When the descending process ends, the two sets of elastic strips 53 can rebound to drive the nozzle 52 to rise, thereby 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, to ensure that the temperature of the chip layer 511 is sufficient to enhance the chemotherapy effect in the lesion area without causing 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 enhancing the chemotherapy effect.

[0093] In this embodiment, when the slide plate 24 moves, it will drive the moving tube 26 and the feeding tube 27 to move synchronously, and the feeding tube 27 will drive the toothed plate 56 to slide on the upper end of the sawtooth plate 55, and the toothed grooves of the toothed plate 56 and the sawtooth plate 55 cooperate to make the nozzle 52 vibrate, and when the nozzle 52 vibrates, the elastic strip 53 can be used to achieve rapid reciprocating vibration of the nozzle 52, and reduce damage to the nozzle 52, which helps to prevent the chemotherapeutic drugs from condensing on the nozzle 52, ensuring that the chemotherapeutic drugs can be evenly sprayed on the lesion area, and then the chemotherapeutic liquid enters the elastic tube 54 and the nozzle 52 through the feeding tube 27, and the chemotherapeutic liquid is sprayed from the nozzle 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 through the diffusion layer 512, thereby heating the lesion area to improve the permeability and efficacy of the chemotherapeutic drugs.

[0094] The working principle of the present invention is as follows: the guide wire tube 13 and the additional tube 15 are extended into the patient's body, and the airbag 32 on the additional tube 15 is moved to the bottom of the lesion, and then the hollow motor 14 drives the additional tube 15 to rotate, so that the nozzle 52 is aimed at the lesion area, and 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 limit tube 41, and then drive the slide plate 24 to move synchronously, and the slide plate 24 drives the sealing plate 31 and the airbag 32 above to move until it is located above the lesion. At this time, the slide plate 24 will also drive the moving tube 26 and the feeding tube 27 to move synchronously, and the feeding tube 27 drives the toothed plate 56 to slide on the upper end of the sawtooth plate 55, and the toothed grooves of the toothed plate 56 and the sawtooth plate 55 cooperate to make the nozzle 52 vibrate, so that the nozzle 52 can be self-cleaned. After the heating is completed, the two groups of air bags 32 are inflated through the trachea 1 33 and the trachea 2 34 by an external air pump, so that they expand until they are close to the inner wall of the esophagus and the lesion area is completely sealed. Then the chemotherapy liquid enters the main pipe 21 through the receiving head 22 and is mixed. Then the liquid flows through the hose 23 and the moving pipe 26, flows through the feeding pipe 27, and finally enters the elastic tube 54 and the nozzle 52, and the chemotherapy liquid is sprayed from the nozzle 52 for chemotherapy.

[0095] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
