Description

Technical Field

[0001] The present application relates to the technical field of thermal therapy equipment for esophageal cancer, and in particular to a heat flow constant temperature heating therapy device. Background Art

[0002] At present, the treatment of esophageal cancer is mainly divided into chemotherapy and hyperthermia. Among them, there are two main methods of hyperthermia. One is extracorporeal heating. The advantages of extracorporeal heating are safety and easy operation. However, due to the separation of human tissue, the temperature of extracorporeal heating cannot be too high. Therefore, it is difficult for the lesion area to reach the clinically required treatment temperature. The other is intracavitary heating. The intracavitary heating method is closer to the lesion and can obtain a more ideal treatment effect compared to extracorporeal heating.

[0003] Intracavity heating mainly relies on the liquid circulation structure to directly make thermal contact with the diseased area. Specifically, the liquid circulation structure includes components such as a balloon, a pipeline, and an external liquid supply assembly. The balloon is connected to the external liquid supply assembly through a pipeline, and the constant temperature liquid circulates in the liquid circulation structure to continuously heat the diseased area at a constant temperature.

[0004] However, the lesions in the esophagus are not distributed in a centralized manner, that is, multiple lesions are randomly distributed at various locations on the inner wall of the esophagus, and the thermal contact of the lesions needs to last for a certain period of time. Therefore, if a single balloon is used to heat the lesions one by one, the entire treatment time will be greatly increased, causing the patient to suffer great pain. If multiple balloons are used to heat at the same time, although the treatment time can be shortened, the total volume of the multiple balloons is too large, which will cause the patient's esophagus to withstand considerable squeezing force, seriously affecting the treatment experience, and multiple balloons are almost difficult to control synchronously. Summary of the invention

[0005] Based on this, it is necessary to provide a heat flow constant temperature heating treatment device to solve the problem that the existing intracavitary heating method is difficult to meet the requirements of treating multiple lesions at the same time without affecting the patient's treatment experience.

[0006] The thermal flow constant temperature heating treatment device provided by the present application includes: an inner tube detection device and a multi-tube structure, the inner tube detection device is used to detect the distribution of lesions in the esophagus, and can output the distribution image of the lesions through a computer to locate the locations of multiple lesions in the esophagus; multiple liquid flow tubes are bundled to form a clustered multi-tube structure; the outer peripheral side of the multi-tube structure is divided into a heating area and a heat insulation area composed of different liquid flow tubes, the temperature of the heat insulation area is lower than the temperature of the heating area, and heat therapy liquid can be passed into at least part of the liquid flow tubes to maintain the temperature of the heating area within a preset range; the distribution of the multiple heating areas is set to correspond to the location of at least part of the lesions, and the heating areas can be set to fit the lesions.

[0007] In one embodiment, the liquid flow tube is a metal part, and multiple liquid flow tubes are wound around each other to form a spirally wound multi-tube structure, and at least one liquid flow tube is used to pass a thermotherapy liquid, so that a heating area can be formed at each location on the outer surface of the liquid flow tube where the thermotherapy liquid is passed, and a heat insulation area can be formed at each location on the liquid flow tube where the thermotherapy liquid is not passed.

[0008] In one embodiment, adjacent liquid flow tubes are bonded by insulating adhesive.

[0009] In one embodiment, the heat flow constant temperature heating treatment device also includes a positioning main pipe and a first drive motor, the positioning main pipe includes a plurality of positioning branch pipes connected in sequence along its own axis, and adjacent positioning branch pipes are connected by a locking structure. When the positioning main pipe is extended into the esophagus, any positioning branch pipe can only rotate in a single direction relative to the adjacent positioning branch pipe and cannot rotate in the opposite direction; a plurality of liquid flow pipes are arranged around the circumference of the positioning main pipe, and the corresponding parts of each liquid flow pipe are fixedly connected to each positioning branch pipe respectively; the liquid flow pipes are divided into a heat therapy tube for passing a heat therapy liquid and a low temperature tube for passing a normal temperature liquid, the temperature of the normal temperature liquid is lower than that of the heat therapy liquid, and the heat therapy tube and the low temperature tube are alternately distributed along the circumference of the positioning main pipe; the liquid flow tubes are all elastic parts, the first drive motor can control its own output shaft to move along the axial direction of the positioning main pipe, and the output shaft of the first drive motor can respectively control each positioning branch pipe to rotate unidirectionally by a specific angle along a preset direction, so that the positioning branch pipe can drive the corresponding liquid flow tube to twist along the preset direction, thereby making the outer surface of the heat therapy tube fit the corresponding lesion.

[0010] In one of the embodiments, when the positioning main pipe is extended into the esophagus, adjacent positioning branch pipes are arranged in an upper and lower position, and the locking structure includes a slide groove arranged on the upper positioning branch pipe, a clamping groove arranged on the lower positioning branch pipe, and a locking tongue, one end of the locking tongue is arranged in the slide groove and can slide with the inner wall of the slide groove along the axial direction of the positioning main pipe, the other end of the locking tongue is movably inserted in the clamping groove, and the lower positioning branch pipe is provided with a plurality of clamping grooves along its own circumferential direction; when the slide groove and the clamping groove are aligned, under the action of gravity, one end of the locking tongue can fall into the corresponding clamping groove; when the upper positioning branch pipe rotates unidirectionally along a preset direction, the locking tongue can retract into the slide groove under the pushing action of the clamping groove; when the upper positioning branch pipe has a tendency to rotate in the opposite direction under the elastic force of the liquid flow tube, the inner wall of the clamping groove can provide a stopping effect on the locking tongue to prevent the upper positioning branch pipe from rotating relative to the lower positioning branch pipe.

[0011] In one of the embodiments, an inclined surface is provided at one end of the lock tongue facing the preset direction. When the positioning branch pipe rotates along the preset direction, the inner wall of the slot can provide a vertical component of force to the lock tongue to push the lock tongue to retract into the slide slot; a vertical stop surface is provided at one end of the lock tongue away from the preset direction. When the positioning branch pipe rotates in a direction opposite to the preset direction, the force exerted by the inner wall of the slot on the stop surface is in a horizontal direction, so that the lock tongue cannot retract into the slide slot.

[0012] In one embodiment, the heat flow constant temperature heating therapy device also includes a movable sleeve and a second drive motor. The movable sleeve can be rotatably mounted on the outer peripheral side of the corresponding liquid flow tube. The movable sleeve includes a heat insulating part and a heat conducting part arranged along its own circumferential direction and fixedly connected.

The second drive motor can control the drive head at its output end to move along the axial direction of the adjustment cavity; each liquid flow tube can be respectively introduced with heat therapy liquid, and the drive head of the second drive motor can respectively drive each movable sleeve to rotate around the corresponding liquid flow tube, so that the heat conducting part of the movable sleeve rotates to the side of the liquid flow tube away from the adjustment cavity to form a heating area, or the heat insulating part of the movable sleeve rotates to the side of the liquid flow tube away from the adjustment cavity to form a heat insulating area.

[0013] In one embodiment, each movable sleeve includes a plurality of sub-sleeves arranged in sequence along its own axis, and each sub-sleeve can independently rotate around a corresponding liquid flow tube.

[0014] In one embodiment, the driving head of the second driving motor can be frictionally matched with the movable sleeve, so that the driving head can drive the movable sleeve to rotate relative to the liquid flow tube through friction.

[0015] In one embodiment, the internal channel of the liquid flow tube is divided into two, the internal channel close to the central axis of the multi-tube structure is set as a reflux channel, and the internal channel away from the central axis of the multi-tube structure is set as an inlet channel.

Furthermore, since the multi-tube structure is formed by a plurality of liquid flow tubes, the multi-tube structure only needs to change the heat shielding area to change or increase the number of heating areas. Compared with the method of adding balloons, the multi-tube structure will not increase the patient's pain and can significantly improve the patient's treatment experience.

DETAILED DESCRIPTION

[0026] At present, the treatment of esophageal cancer is mainly divided into chemotherapy and hyperthermia. Among them, there are two main methods of hyperthermia. One is extracorporeal heating. The advantages of extracorporeal heating are safety and easy operation. However, due to the separation of human tissue, the temperature of extracorporeal heating cannot be too high. Therefore, it is difficult for the lesion area to reach the clinically required treatment temperature. The other is intracavitary heating. The intracavitary heating method is closer to the lesion and can obtain a more ideal treatment effect compared to extracorporeal heating.

[0027] Intracavity heating mainly relies on the liquid circulation structure to directly make thermal contact with the diseased area. Specifically, the liquid circulation structure includes components such as a balloon, a pipeline, and an external liquid supply assembly. The balloon is connected to the external liquid supply assembly through a pipeline, and the constant temperature liquid circulates in the liquid circulation structure to continuously heat the diseased area at a constant temperature.

[0028] However, the lesions in the esophagus are not distributed in a centralized manner, that is, multiple lesions are randomly distributed at various locations on the inner wall of the esophagus, and the thermal contact of the lesions needs to last for a certain period of time. Therefore, if a single balloon is used to heat the lesions one by one, the entire treatment time will be greatly increased, causing the patient to suffer great pain. If multiple balloons are used to heat at the same time, although the treatment time can be shortened, the total volume of the multiple balloons is too large, which will cause the patient's esophagus to withstand considerable squeezing force, seriously affecting the treatment experience, and multiple balloons are almost difficult to control synchronously.

[0029] See also Figure 1-Figure 7 In order to solve the problem that the existing intracavitary heating method is difficult to meet the requirements of treating multiple lesions at the same time without affecting the patient's treatment experience, the present application provides a heat flow constant temperature heating treatment device.

[0030] The thermal flow constant temperature heating treatment device provided in the present application includes an inner tube detection device and a multi-tube structure 100. The inner tube detection device is used to detect the distribution of lesions in the esophagus, and can output the distribution image of the lesions through a computer to locate the locations of multiple lesions in the esophagus; multiple liquid flow tubes 110 are clustered to form a clustered multi-tube structure 100; the outer peripheral side of the multi-tube structure 100 is divided into a heating area 120 and an insulation area 130 composed of different liquid flow tubes 110, the temperature of the insulation area 130 is lower than the temperature of the heating area 120, and at least part of the liquid flow tubes 110 can be passed into a thermal therapy liquid to maintain the temperature of the heating area 120 within a preset range; the distribution of the multiple heating areas 120 is set to correspond to the location of at least part of the lesions, and the heating areas 120 can be set to fit the lesions.

[0031] Specifically, the assembly and use of the heat flow constant temperature heating treatment device are as follows:

[0032] A plurality of liquid flow tubes 110 are bundled and arranged to form a clustered multi-tube structure 100;

[0033] It should be noted that the plurality of liquid flow tubes 110 may be fixed together by a buckle structure, or may be connected together by bonding or twisting. Specifically, in one embodiment, adjacent liquid flow tubes 110 are bonded by insulating glue to prevent heat transfer between adjacent liquid flow tubes 110.

[0034] Furthermore, the cluster arrangement refers to that the liquid flow tubes 110 are arranged in a concentrated bundle. In this case, the plurality of liquid flow tubes 110 may be arranged in parallel or in a non-parallel manner.

[0035] Locate the locations of multiple lesions in the esophagus (not shown);

[0036] According to the distribution position of the lesions, a part of the multi-tube structure 100 is thermally shielded, so that the outer peripheral side of the multi-tube structure 100 is divided into a heating area 120 and a heat insulation area 130, and the distribution of the plurality of heating areas 120 is set corresponding to the position of at least part of the lesions;

[0037] It should be noted that when the number of lesions is small, the distribution of the multiple heating areas 120 is set corresponding to the positions of all lesions. When the number of lesions is too large, multiple thermal treatments can be performed.

[0038] According to the position of the corresponding lesion, the heating area 120 is arranged to fit the lesion;

[0039] It should be noted that the arrangement of the heating area 120 and the lesion in close contact specifically includes the following methods: in one embodiment, a dedicated inner tube detection device such as an endoscope or a detector is used to detect the distribution of the lesions in the esophagus in advance, and a distribution image of the lesions is output through a computer. Afterwards, a portion of the multi-tube structure 100 is heat-shielded outside the esophagus, and then the multi-tube structure 100 with the heating area 120 and the heat-insulating area 130 set is placed in a designated area of ​​the esophagus according to the distribution image of the lesions.

[0040] With such an arrangement, the detection of the distribution of lesions and the placement of the multi-tube structure 100 are performed separately, and the heat shielding of the multi-tube structure 100 is performed outside the esophagus, which is conducive to reducing the operational difficulty of the above process and improving the operational efficiency.

[0041] Furthermore, it should be noted that the process of placing the multi-tube structure 100 into the esophagus is performed by professional medical personnel, who can accurately place the multi-tube structure 100 based on the distribution image of the lesions and the structure of the esophagus. If a more precise placement effect is required, a scale or other calibration object can be set on the outer wall of the multi-tube structure 100.

[0042] In another embodiment, a dedicated inner tube detection device may be arranged in front of the multi-tube structure 100 (that is, the inner tube detection device enters the esophagus first), and the inner tube detection device is electrically connected to a computer, and the computer can display the detection image of the inner tube detection device in real time;

[0043] When the multi-tube structure 100 moves in the esophagus, medical staff can perform heat shielding on the multi-tube structure 100 in real time according to the lesion distribution image displayed by the computer, so that the heating area 120 can be synchronously fitted with the lesion.

[0044] Such an arrangement can greatly improve the fitting accuracy between the heating area 120 and the lesion.

[0045] Furthermore, a thermal therapy liquid (which may be pure water, saline or other aqueous solutions) is introduced into at least a portion of the liquid flow tube 110 to maintain the temperature of the heating area 120 within a preset range (between 39.5° C. and 45° C.).

[0046] It should be noted that, in order to facilitate the reflux of the thermal treatment liquid and not affect the treatment effect of the liquid flow tube 110, in one embodiment, Figure 2 and Figure 5 As shown, the internal channel of the liquid flow tube 110 is divided into two, wherein the internal channel close to the central axis of the multi-tube structure 100 (i.e., away from the inner wall of the esophagus) is the reflux channel 114, and the internal channel away from the central axis of the multi-tube structure 100 (i.e., close to the inner wall of the esophagus) is the inlet channel 113.

[0047] However, it is not limited thereto. In other embodiments, the liquid flow tube 110 may also be in the form of a double-layer casing, with an inner casing for return flow and a sandwich between the outer casing and the inner casing for inflow flow.

[0048] It is understandable that, since the multi-tube structure 100 performs heat shielding, the heat-insulating area 130 corresponding to the normal esophageal tissue will not generate a high temperature, thereby preventing the normal esophageal tissue from being scalded by the thermal therapy liquid.

[0049] With such a configuration, on the one hand, a heat-insulating area 130 can be formed by heat shielding to prevent the high temperature of the thermotherapy liquid from damaging normal esophageal tissue; on the other hand, multiple heating areas 120 can be arranged according to the distribution image of the lesions, so that the multi-tube structure 100 can treat multiple lesions at one time, greatly reducing the treatment time of the patient and improving the treatment efficiency. Furthermore, since the multi-tube structure 100 is formed by a cluster arrangement of multiple liquid flow tubes 110, the multi-tube structure 100 only needs to change the heat shielding area to change or increase the number of heating areas 120. Compared with the method of adding balloons, the multi-tube structure 100 will not increase the pain of the patient and can significantly improve the patient's treatment experience.

[0050] It should be noted that there are several embodiments of dividing the outer circumference of the multi-tube structure 100 into the heat-generating area 120 and the heat-insulating area 130 as follows.

[0051] Embodiment 1

[0052] like Figure 1 As shown, the liquid flow tube 110 is a metal part, and a plurality of liquid flow tubes 110 are mutually wound to form a spirally wound multi-tube structure 100, and at least one liquid flow tube 110 is used to pass a thermotherapy liquid, so that a heating area 120 can be formed at various locations on the outer surface of the liquid flow tube 110 (the surface away from the central axis of the multi-tube structure 100) where the thermotherapy liquid is passed, and a heat insulation area 130 can be formed at various locations of the liquid flow tube 110 where the thermotherapy liquid is not passed.

[0053] In this embodiment, the heat shielding method of the multi-tube structure 100 is to divide the liquid flow tube 110 into a liquid flow tube 110 that passes through the thermotherapy liquid and a liquid flow tube 110 that does not pass through the thermotherapy liquid, and the two are wound together so that the liquid flow tube 110 that does not pass through the thermotherapy liquid can be wound to form a heat insulation area 130. At the same time, the liquid flow tube 110 that passes through the thermotherapy liquid can be synchronously distributed along the circumference and axial direction of the multi-tube structure 100, so as to facilitate the heating area 120 of the multi-tube structure 100 to synchronously fit the multiple lesions randomly distributed in the esophagus.

[0054] It should be noted that the method of the first embodiment can only perform heat shielding on a partial area of ​​the multi-tube structure 100 outside the esophagus.

[0055] With such arrangement, the heat shielding method of the multi-tube structure 100 is relatively simple. When the number of lesions is small, the lesions can be quickly treated by the method of the first embodiment.

[0056] Furthermore, in one embodiment, the number of the liquid flow tubes 110 is two, but not limited thereto. In other embodiments, the number of the liquid flow tubes 110 may be three, four, five, etc., which are not listed here one by one.

[0057] Embodiment 2

[0058] like Figure 2-Figure 4 As shown, the heat flow constant temperature heating treatment device also includes a positioning main pipe 200 and a first drive motor 300. The positioning main pipe 200 includes a plurality of positioning branch pipes 210 connected in sequence along its own axis. Adjacent positioning branch pipes 210 are connected by a locking structure. When the positioning main pipe 200 is extended into the esophagus, any positioning branch pipe 210 can only rotate in a single direction (clockwise or counterclockwise) relative to the adjacent positioning branch pipe 210 and cannot rotate in the opposite direction.

[0059] Each liquid flow tube 110 extends along the axial direction of the positioning main pipe 200, and multiple liquid flow tubes 110 are arranged around the circumference of the positioning main pipe 200, and the corresponding parts of each liquid flow tube 110 are fixedly connected to each positioning branch pipe 210 (including but not limited to bonding, fastener connection and clamping).

[0060] The liquid flow tube 110 is divided into a thermotherapy tube 111 for passing thermotherapy liquid and a cryogenic tube 112 for passing normal temperature liquid (temperature value is between 10°C-37°C). The temperature of the normal temperature liquid is lower than the temperature of the thermotherapy liquid, and the thermotherapy tube 111 and the cryogenic tube 112 are alternately distributed along the circumference of the positioning main pipe 200.

[0061] The liquid flow tubes 110 are all elastic parts. Specifically, the liquid flow tubes 110 can be rubber tubes, silicone tubes or other elastic tubes. Since the thermal conductivity of rubber tubes and silicone tubes is average, the temperature of the introduced heat therapy liquid can be increased as needed.

[0062] The first drive motor 300 can control its output shaft to move along the axial direction of the positioning main pipe 200, and the output shaft of the first drive motor 300 can respectively control each positioning branch pipe 210 to rotate unidirectionally by a specific angle along a preset direction (clockwise or counterclockwise), so that the positioning branch pipe 210 can drive the corresponding liquid flow tube 110 to twist along the preset direction, thereby allowing the outer surface of the thermal therapy tube 111 to fit the corresponding lesion.

[0063] It should be noted that since the temperature of the heat therapy liquid is not much different from the normal body temperature of the human body, generally not exceeding 45°C, even if part of the heat therapy tube 111 comes into contact with the normal inner wall of the esophagus after twisting, it is only necessary to control the heat therapy time to avoid the heat therapy tube 111 from damaging the normal skin of the esophagus.

[0064] In such a configuration, since the liquid flow tube 110 is an elastic member, on the one hand, it is beneficial for the elastic liquid flow tube 110 to adapt to the twisting process by its own elongation, thereby facilitating the positioning branch 210 to rotate the corresponding thermal therapy tube 111 to the position of the lesion; on the other hand, the elastic liquid flow tube 110 has a better fitting effect, which is beneficial for the liquid flow tube 110 to better fit the surface of the lesion and heat the lesion, and the elastic liquid flow tube 110 can reduce damage to the esophageal skin.

[0065] Preferably, in one embodiment, the number of the liquid flow tubes 110 is two, but not limited thereto. In other embodiments, the number of the liquid flow tubes 110 may be three, four, five, etc., which are not listed here one by one.

[0066] It should be noted that the method of the second embodiment can perform heat shielding on a partial area of ​​the multi-tube structure 100 outside the esophagus, and can also perform heat shielding on a partial area of ​​the multi-tube structure 100 inside the esophagus.

[0067] Furthermore, in one embodiment, when the positioning main pipe 200 is extended into the esophagus, adjacent positioning branch pipes 210 are arranged in an upper and lower position, and the locking structure includes a slide groove 211 of the positioning branch pipe 210 arranged at the upper side, a clamping groove 212 of the positioning branch pipe 210 arranged at the lower side, and a locking tongue 221. One end of the locking tongue 221 is arranged in the slide groove 211 and can slide with the inner wall of the slide groove 211 along the axial direction of the positioning main pipe 200, and the other end is movably inserted in the clamping groove 212, and a plurality of clamping grooves 212 are distributed along the circumferential direction of the positioning branch pipe 210 at the lower side.

[0068] When the slide groove 211 and the locking groove 212 are aligned, under the action of gravity, one end of the locking tongue 221 can fall into the locking groove 212 of the positioning branch pipe 210 located below;

[0069] When the upper positioning branch pipe 210 rotates unidirectionally along a preset direction, the locking tongue 221 can be retracted into the sliding groove 211 under the pushing action of the locking groove 212;

[0070] When the upper positioning branch pipe 210 has a tendency to rotate in the opposite direction under the elastic force of the liquid flow pipe 110 , the inner wall of the slot 212 can provide a stop for the locking tongue 221 to prevent the upper positioning branch pipe 210 from rotating relative to the lower positioning branch pipe 210 .

[0071] With such arrangement, when the adjacent positioning branches 210 rotate relative to each other at a specific angle, the locking tongue 221 can fall into the corresponding locking groove 212 and play a role in preventing rotation. In addition, since the rotation direction of the positioning branches 210 and the contraction direction of the liquid flow tube 110 must be opposite, the liquid flow tube 110 and the locking groove 212 can balance the force of the locking tongue 221, greatly improving the locking stability of the lock structure.

[0072] Furthermore, since the locking tongue 221 is a gravity structure, when the multi-tube structure 100 leaves the esophagus, the multi-tube structure 100 can be turned upside down, so that the locking tongue 221 can be retracted into the slide groove 211 under the action of gravity, and the liquid flow tube 110 can drive the positioning branch tube 210 to reset.

[0073] But not limited to this, in other embodiments, the locking structure can also be an electrically controlled buckle structure.

[0074] Furthermore, in one embodiment, an end of the locking tongue 221 facing the preset direction is provided with a slope 2211 arranged obliquely downward, and the slope 2211 can decompose the force of the slot 212 on the locking tongue 221 into a vertical force and a horizontal force. When the positioning branch 210 rotates along the preset direction, the locking tongue 221 can retract into the slide slot 211 under the pushing action of the inner wall of the slot 212 providing a vertical force on the locking tongue 221.

[0075] But not limited thereto, in other embodiments, the inclined surface 2211 may be replaced by a curved surface.

[0076] Correspondingly, a vertically arranged stop surface 2212 is provided at one end of the locking tongue 221 which deviates from the preset direction. When the positioning branch 210 rotates in a direction opposite to the preset direction, the inner wall of the slot 212 exerts a force on the stop surface 2212 in a horizontal direction. Under the stopping action of the stop surface 2212, the locking tongue 221 cannot be retracted.

[0077] In one embodiment, the output shaft of the first drive motor 300 is a telescopic shaft structure, and a stop head 310 is fixedly connected to one end of the output shaft of the first drive motor 300 away from the motor body. The cross-section of the stop head 310 perpendicular to the axial direction of the positioning main pipe 200 is non-circular, and the cross-section of the inner wall of the positioning main pipe 200 perpendicular to its own axial direction is also non-circular, and the stop head 310 and the inner wall of the positioning main pipe 200 can slide and fit along the axial direction of the positioning main pipe 200, and the stop head 310 and the inner wall of the positioning main pipe 200 are stop-rotating fit.

[0078] Specifically, the cross-section of the stopper 310 and the cross-section of the inner wall of the positioning main pipe 200 can be a triangle, a quadrilateral, a pentagon, etc., which are not listed here one by one.

[0079] Embodiment 3

[0080] like Figure 5-Figure 7 As shown, the heat flow constant temperature heating treatment device also includes a movable sleeve 500 and a second driving motor 400. The movable sleeve 500 can be rotatably sleeved on the outer peripheral side of the corresponding liquid flow tube 110. The movable sleeve 500 includes a heat insulation part 510 and a heat conduction part 520 arranged along its own circumferential direction and fixedly connected, that is, one side of the movable sleeve 500 is the heat insulation part 510, and the other side of the movable sleeve 500 is the heat conduction part 520. The heat insulation part 510 and the heat conduction part 520 are both long strips extending along the axial direction of the liquid flow tube 110.

[0081] Specifically, the material of the heat insulating part 510 includes but is not limited to aerogel felt, vacuum plate, silica gel and other materials, and the material of the heat conducting part 520 includes but is not limited to metal materials such as aluminum alloy, copper alloy, stainless steel or non-metal materials such as graphene.

[0082] The plurality of liquid flow tubes 110 are arranged to form an adjustment chamber 140 extending axially along the multi-tube structure 100 . The second drive motor 400 can control the drive head 410 at the output end to move axially along the adjustment chamber 140 .

[0083] Each liquid flow tube 110 can be respectively introduced with thermal therapy liquid, and the driving head 410 of the second driving motor 400 can respectively drive each movable sleeve 500 to rotate around the corresponding liquid flow tube 110, so that the heat conductive part 520 of the movable sleeve 500 is rotated to the side of the liquid flow tube 110 away from the regulating chamber 140 to form a heating area 120, or, the heat insulating part 510 of the movable sleeve 500 is rotated to the side of the liquid flow tube 110 away from the regulating chamber 140 to form a heat insulating area 130.

[0084] It should be noted that the driving head 410 can be eccentrically moved toward any side (ie, the direction of different liquid flow tubes 110 ) in the adjustment chamber 140 to adjust the corresponding movable sleeve 500 .

[0085] With such a configuration, it is possible to accurately control whether the side of each liquid flow tube 110 corresponding to the inner wall of the esophagus is the heating area 120 or the insulation area 130, thereby enabling each lesion area to receive accurate thermal therapy without affecting the normal esophageal area.

[0086] By reducing the diameter of the liquid flow tube 110 and increasing the number of the liquid flow tubes 110 , a very high thermal therapy accuracy can be achieved.

[0087] It should be noted that the method of the third embodiment can perform heat shielding on a partial area of ​​the multi-tube structure 100 outside the esophagus, and can also perform heat shielding on a partial area of ​​the multi-tube structure 100 inside the esophagus.

[0088] Furthermore, in one embodiment, each movable sleeve 500 includes a plurality of sub-sleeves 530 arranged in sequence along its own axial direction, and each sub-sleeve 530 can independently rotate around the corresponding liquid flow tube 110 .

[0089] It should be noted that the sub-sleeve 530 also includes a heat insulating portion 510 and a heat conducting portion 520 arranged along its circumferential direction and fixedly connected.

[0090] Such an arrangement enables the liquid flow tube 110 to form a plurality of heating areas 120 and heat insulation areas 130 along its own axial direction, thereby greatly improving the degree of freedom of treatment of the multi-tube structure 100 .

[0091] Furthermore, in one embodiment, the driving head 410 of the second driving motor 400 can be frictionally matched with the movable sleeve 500, so that the driving head 410 can drive the movable sleeve 500 to rotate relative to the liquid flow tube 110 through friction.

[0092] However, the present invention is not limited thereto. In other embodiments, the driving head 410 of the second driving motor 400 can also drive the movable sleeve 500 to rotate relative to the liquid flow tube 110 through a gear structure. Specifically, the outer wall of the driving head 410 of the second driving motor 400 is provided with a latching tooth, and the surface of the movable sleeve 500 is provided with a tooth groove corresponding to the latching tooth, and the latching tooth drives the movable sleeve 500 to rotate through the tooth groove.
