Description

Technical Field

[0001] The present invention relates to the medical field, and specifically to a visualization device for treating esophageal cancer. Background Art

[0002] The current treatment methods mainly rely on blind treatment by doctors based on their feeling after positioning with ultrasound or X-ray. Its disadvantages are as follows: The treatment intensity is difficult to control. Either the treatment intensity is increased for fear of incomplete treatment, which may damage normal tissues; or some untreated points are left, leaving a hidden danger for later recurrence. When the existing ablation needles are performing ablation, the position and angle of the ablation needles need to be continuously adjusted to make the ablation needles fit at the positions of the cells to be ablated. The operation process is difficult and time-consuming. Moreover, when the position of the ablation needle needs to be adjusted, problems such as excessive adjustment and over-long retraction will occur. Therefore, during the adjustment process, slow adjustment is required to prevent excessive adjustment size, which makes the operation process need to be carried out carefully and requires sufficient experience to complete the operation.

[0012] Beneficial effects:

[0013] (1) The treatment intensity of the ablation needle can be changed by the host; the host can control the flow rate and flow velocity of the drug; the camera component can adjust the focus and brightness to adjust the clarity. The camera component has a flexible high-definition lighting, display and recording lens, which can clearly and visually display the situation of the treatment site with the display screen on the host; it can also be used for separate inspection; the drug supply component and ablation component are disposable, and the drug supply component and ablation component can be removed from the inside of the camera component; a variety of accessories can be inserted into the host, and the accessories can be selected as: inspection accessories, inspection and treatment accessories. The device can be used for the inspection and treatment of some early tumors in the human body; the suspension mechanism can be used to hang a drug bottle or a drug bag; the drug supply component can be set according to different conditions. 1-4 small channels can be set, one channel is used for saline flushing, which can achieve the disinfection effect and clearly observe the effect after treatment; the second, third and fourth channels are used for different types of drug administration and are set differently, such as: pure disinfection, liquid drugs, semi-solid drugs. The ablation component is arranged to be able to extend out of the interior of the camera component. When the ablation component is extended, it is convenient for it to contact with cancer cells inside the human body, thereby reducing the need for constant adjustment of the ablation component inside the human body. After the ablation component ablates the cancer cells, the drug supply component supplies drugs to the ablated area, thereby achieving accurate point drug delivery. Accurate drug delivery can be performed on the wound caused by ablation, allowing the patient to recover faster and enhancing the treatment effect.

[0014] (2) The camera can be installed to observe the inside of the human esophagus as the cannula enters, making it easier to deliver the ablation component to the location corresponding to the early cancer cells. Since the camera component is relatively expensive, the drug supply component and ablation component inside it can be disassembled after use, and the camera component can be reused.

[0015] (3) When the drug supply assembly needs to be installed inside the cannula, a traction rope is installed on the hanging hole. The movement of the traction rope drives the stabilizing plate to move. The movement of the stabilizing plate pulls the hard tube to drive the soft tube to move synchronously until the hard tube drives the positioning mechanism to enter the inside of the positioning hole, so that the hard tube will not leave the inside of the positioning hole during the movement process.

[0016] (4) When ablation is required, the ablation coil is unfolded. When cell ablation is not required, the ablation coil is stored inside the cannula, and the stored ablation coil will not affect the process of the cannula entering the esophagus. The extension of the ablation coil is controlled by inflating the inside of the ablation coil. The unfolded ablation coil will be located outside the cannula. After unfolding, the ablation coil will fit on the cells, so that when ablating cells, there is no need to frequently adjust the position of the ablation coil, thereby reducing the difficulty of the operation and improving the efficiency of the operation.

[0017] (5) The extended positioning block can only move forward along the positioning hole. When the positioning block moves backward, it will be stuck inside the limiting hole and cannot move backward. When the gas inside the air hole enters the inside of the outer blocking rod through the delivery hole, the outer blocking rod will move along the inner blocking rod. The movement of the outer blocking rod will extend into the inside of the limiting hole. The outer blocking rod inside the limiting hole is limited by the limiting hole and can only move backward but not forward. Therefore, when adjusting the hard tube, the position of the hard tube that can be adjusted is limited.

[0018] (6) Since the guide groove is composed of a horizontal groove and an inclined groove, when the guide rod moves, the guide rod first moves from the horizontal groove and then enters the interior of the inclined groove, so that the push plate first moves horizontally and then approaches the hardened tube, and pushes the hardened tube to move, thereby adjusting the movement and adjustment of the drug supply component and the ablation component.

[0033] By setting the main unit 1, the treatment intensity of the ablation needle can be changed; the main unit 1 can control the flow rate and velocity of the drug; by the camera component 4, the focal length and brightness can be adjusted to adjust the clarity. The camera component 4 has a flexible high-definition lighting, display and recording lens, and can clearly display the situation of the treatment site on the display screen of the main unit 1; it can also be used for separate inspections; by setting the drug supply component 5 and the ablation component 6 to be disposable, the drug supply component 5 and the ablation component 6 can be detached from the inside of the camera component 4; various accessories can be inserted on the main unit 1, and the accessories can be selected as: inspection accessories, inspection and treatment accessories. This device can be used for the inspection and treatment of some early tumors in the human body; by setting the suspension mechanism 2, a medicine bottle or a medicine bag can be suspended; by setting the drug supply component 5, according to different conditions, 1-4 small channels can be set. One channel is used for saline flushing, which can not only achieve a disinfection effect but also clearly observe the effect after treatment; the second, third, and fourth channels are set differently according to different drug types, such as: pure disinfection drugs, liquid drugs, semi-solid drugs. By setting the ablation component 6, it can extend out of the inside of the camera component 4. After the ablation component 6 extends, it is convenient to contact the cancer cells inside the human body, reducing the situation where the ablation component 6 needs to be continuously adjusted inside the human body; after the ablation component 6 ablates the cancer cells, the drug supply component 5 supplies drugs to the ablated area, realizing accurate point drug delivery, and can accurately deliver drugs to the wound caused by ablation, enabling the patient to recover faster and enhancing the treatment effect.

[0034] The camera component 4 includes a signal line 43 connected to the main unit 1, the signal line 43 is arranged inside an intubation tube 41, and the intubation tube 41 is inserted into the human body; a camera 42 is arranged inside the intubation tube 41, an inner groove 44 is arranged inside the intubation tube 41, and the signal line 43 is arranged inside the inner groove 44; a movable drug supply component 5 is arranged inside the intubation tube 41.

[0035] The camera 42 is arranged to observe when the cannula 41 enters the human esophagus, so as to facilitate the delivery of the ablation component 6 to the position corresponding to the early cancer cells; since the cost of the camera component 4 is relatively high, the drug supply component 5 and the ablation component 6 inside it can be disassembled after use, and the camera component 4 can be reused.

[0036] The drug supply component 5 includes a hard tube 51, a hose 56 is provided at the end of the hard tube 51, a hardened tube 59 is connected to the hose 56, a second elastic member 510 is provided on one side of the hardened tube 59, and the second elastic member 510 is used to push the hardened tube 59 to reset; a plurality of drug supply channels 52 are provided inside the hard tube 51, and a one-way valve 53 is installed inside the drug supply channels 52 respectively; a stabilizing plate 54 is provided on the hard tube 51, and a hanging hole 55 is provided on the stabilizing plate 54, and the hanging hole 55 is used to connect a traction rope; a positioning hole 57 and a mounting hole 58 are provided inside the insertion tube 41, and the hard tube 51 is slidably provided inside the positioning hole 57 and the mounting hole 58, and the ablation component 6 is provided on the hard tube 51.

[0037] The hardened tube 59 provided can facilitate movement inside the cannula 41. The hardened tube 59 drives the ablation component 6 to move synchronously during the adjustment process. After the cannula 41 is inserted into the esophagus, when the ablation component 6 needs to be adjusted to the position of the cancer cells, the adjustment can be completed by moving the hard tube 51. When the drug supply component 5 needs to be installed inside the cannula 41, a traction rope is installed on the hanging hole 55. The movement of the traction rope drives the movement of the stabilizing plate 54. The movement of the stabilizing plate 54 pulls the hard tube 51 to drive the hose 56 to move synchronously until the hard tube 51 drives the positioning mechanism 7 to enter the interior of the positioning hole 57, so that the hard tube 51 will not deviate from the interior of the positioning hole 57 during the movement process.

[0038] The ablation component 6 includes a connecting plate 62 arranged on the hard tube 51, and an ablation circle 61 is arranged on the connecting plate 62. Every two ablation circles 61 are connected by a storage belt 66. A connecting belt 63 is arranged on the outer side of the ablation circle 61 and the connecting plate 62. The connecting belt 63 is used to seal the ablation circle 61. A first guide rod 64 is arranged on the hard tube 51, and a second guide rod 65 is arranged on the first guide rod 64. The first guide rod 64 slides inside the second guide rod 65, and the second guide rod 65 is connected to the inner wall of the ablation circle 61. An air guide hole 67 is arranged on the hard tube 51, and the air guide hole 67 is connected to an air pump arranged inside the main unit 1. An air hole is arranged on the connecting plate 62. When the air guide hole 67 ventilates into the interior of the ablation circle 61, the ablation circle 61 unfolds, and the air hole opens to communicate with the positioning mechanism 7, and the positioning mechanism 7 extends and is stuck in the positioning hole 57.

[0039] The ablation loop 61 can be supported by the provided connecting plate 62. When the air pump inflates the inside of the ablation loop 61 through the air guide hole 67, the gas will expand multiple ablation loops 61 between the two connecting plates 62. When the ablation loop 61 unfolds, the ablation loop 61 drives the connecting belt 63 to unfold. When the connecting belt 63 unfolds, the storage belt 66 unfolds synchronously. At this time, the first guide rod 64 slides inside the second guide rod 65. The first guide rod 64 and the second guide rod 65 play a role in supporting, guiding and positioning, so that the ablation loop 61 will not deflect when stretching; after the ablation loop 61 unfolds, the edge of the connecting plate 62 is a corrugated structure, and the connecting plate will unfold. The connecting plate 62 does not block the air holes, so that the air holes are communicated with the positioning mechanism 7, and the gas inside the air holes is filled into the inside of the positioning mechanism 7. The positioning mechanism 7 extends and is stuck inside the positioning hole 57. When ablation is required, the ablation loop 61 unfolds. When it is not necessary to ablate cells, the ablation loop 61 is stored inside the intubation tube 41, and the stored ablation loop 61 will not affect the process of the intubation tube 41 entering the esophagus. By inflating the inside of the ablation loop 61, the stretching of the ablation loop 61 is controlled. After the ablation loop 61 unfolds, it will be located outside the intubation tube 41. After the ablation loop 61 unfolds, it will fit on the cells, so as to achieve the effect of not needing to frequently adjust the position of the ablation loop 61 when ablating cells, thereby reducing the surgical difficulty and improving the surgical efficiency.

[0040] The positioning mechanism 7 includes a positioning block 71 provided on the rigid tube 51. The positioning block 71 is an elastic structure. The positioning block 71 enters the inside of the positioning hole 57 along the inside of the intubation tube 41, and the positioning hole 57 restricts the reverse movement of the positioning block 71; an inner retaining rod 73 is provided on the rigid tube 51, and an outer retaining rod 72 is sleeved on the inner retaining rod 73. The outer retaining rod 72 slides on the inner retaining rod 73. A third elastic member 75 is provided at the top of the inner retaining rod 73. The third elastic member 75 is used to pull the outer retaining rod 72 back to its original position. A delivery hole 74 is provided inside the inner retaining rod 73. The delivery hole 74 is connected to the air hole. When the gas enters the inside of the outer retaining rod 72 from the inside of the air hole through the delivery hole 74, the outer retaining rod 72 slides on the inner retaining rod 73 and extends into the inside of the positioning hole 57.

[0041] The positioning block 71 moves from the inside of the intubation tube 41. During the movement, the positioning block 71 is in a compressed state. After the positioning block 71 enters the inside of the positioning hole 57, the positioning block 71 expands. At this time, the positioning block 71 is stuck inside the positioning hole 57. At this time, the expanded positioning block 71 can only move forward along the positioning hole 57. When the positioning block 71 moves backward, it will be stuck inside the limiting hole and cannot move backward; when the gas inside the air hole enters the inside of the outer retaining rod 72 through the delivery hole 74, the outer retaining rod 72 will move along the inner retaining rod 73. The movement of the outer retaining rod 72 will extend into the inside of the limiting hole. The outer retaining rod 72 inside the limiting hole is limited by the limiting hole and can only move backward and cannot move forward; therefore, when adjusting the rigid tube 51, the position where the rigid tube 51 is adjusted is limited.

[0042] The holding assembly 3 includes a housing 31. One side of the housing 31 is provided with a detachable cover plate 32. A socket 34 is provided on the cover plate 32. An insertion rod 33 is provided inside the housing 31. The insertion rod 33 cooperates with the socket 34. A grip plate 35 is provided on the housing 31. A moving rod 36 is connected to the grip plate 35. A first elastic member 37 is provided on the moving rod 36. The first elastic member 37 is used to push the moving rod 36 to reset. A connecting pipe 38 is provided on the housing 31. The connecting pipe 38 is connected to the main body 1.

[0043] The cover plate 32 can be covered on the housing 31, which is convenient for taking out the hose 56, the stiffening tube 59 and the second elastic member 510 from the inside of the housing 31. After the air pump stops supplying air, the ablation loop 61 is retracted, and the outer retaining rod 72 will be reset under the pulling of the third elastic member 75. During the reset process of the outer retaining rod 72, it will disengage from the inside of the positioning hole 57; when pulling the rigid tube 51 to drive the hose 56, the stiffening tube 59 and the second elastic member 510 to separate from the inside of the intubation tube 41; through the provided grip plate 35, it is convenient to press with fingers, and through the provided first elastic member 37, it is convenient to push the grip plate 35 to reset after releasing the fingers.

[0044] The telescopic mechanism 8 includes a push rod 81 movably connected to the moving rod 36. A through groove 82 is provided on the push rod 81. A positioning rod 83 is provided inside the through groove 82. The positioning rod 83 is provided on the inner wall of the housing 31. A support plate 801 is provided inside the housing 31. A guide groove 86 and a relief groove 85 are provided on the support plate 801. A guide post 88 is provided inside the guide groove 86. The guide post 88 slides inside the guide groove 86. The guide post 88 is provided on a guide rod 84. A push plate 87 is provided at the end of the guide rod 84. The push plate 87 is used to push the stiffening tube 59 to move; the push rod 81 abuts against the guide rod 84. When the push rod 81 moves, it pushes the guide rod 84 to move.

[0045] When the moving rod 36 moves, the moving rod 36 drives the push rod 81 to flip. When the push rod 81 flips, it rotates around the positioning rod 83. The end part of the rotated push rod 81 will abut against the guide rod 84, and the guide rod 84 will move. When the guide rod 84 moves, relative sliding occurs between the guide rod 84 and the push rod 81. When the guide rod 84 moves, it drives the push plate 87 provided at its end to move. The movement of the push plate 87 gradually approaches the hardening tube 59. The movement of the hardening tube 59 drives the movement of the flexible tube 56, and further drives the movement of the rigid tube 51, realizing the movement of the ablation loop 61. Since the guide groove 86 is composed of a horizontal groove and an inclined groove, when the guide rod 84 moves, the guide rod 84 first moves from the horizontal groove and then enters the inside of the inclined groove, realizing that the push plate 87 first translates and then approaches the hardening tube 59, and pushing the hardening tube 59 to move, realizing the movement and adjustment of the medicine supply assembly 5 and the ablation assembly 6.

[0046] The suspension mechanism 2 includes a stabilizing rod 29 provided on the main body 1. A telescopic rod 21 is slidably provided on the stabilizing rod 29. An upper ring 22 is provided on the telescopic rod 21. A hanging rod 27 is provided on the upper ring 22. A plurality of hooks 28 are provided on the hanging rod 27. The hooks 28 are used for hanging the liquid medicine bag. The telescopic rod 21 and the stabilizing rod 29 are connected by a first fixing button 23. A sliding ring 25 is provided on the stabilizing rod 29. A second fixing button 24 is provided on the sliding ring 25. A lower ring 26 is provided on the sliding ring 25. The lower ring 26 is located below the upper ring 22. The upper ring 22 and the lower ring 26 are cooperatively arranged to place the liquid medicine bottle.

[0047] The cooperation of the provided upper ring 22 and lower ring 26 enables the installation of the bottle-shaped medicine supply bottle. When hanging the liquid supply bag, only need to hang the liquid supply bag on the hook 28. If the height needs to be adjusted, only need to adjust the positions of the first fixing button 23 and the second fixing button 24 to achieve the adjustment.

[0048] When the present invention is in use, the new ablation component 6 and the drug supply component 5 are first disassembled, the traction rope is passed through the hanging hole 55 and installed on the hanging hole 55, so that one end of the traction rope passes through the interior of the cannula 41, and the traction rope is pulled to move to drive the stabilizing plate 54 to move. The stabilizing plate 54 moves and pulls the hard tube 51 to drive the soft tube 56 to move synchronously until the hard tube 51 drives the positioning block 71 to move, and the positioning block 71 moves from the inside of the cannula 41. The positioning block 71 is in a compressed state during the movement, and after the positioning block 71 enters the interior of the positioning hole 57, the positioning block 71 stretches out, and the positioning block 71 is stuck in the interior of the positioning hole 57. At this time, the stretched positioning block 71 can only move forward along the positioning hole 57, and when the positioning block 71 moves backward, it will be stuck in the inside of the limiting hole and cannot move backward; therefore, when adjusting the hard tube 51, the adjusted position of the hard tube 51 is limited. Then connect the camera assembly to the host, connect the power cord and the signal line 43 stably, then turn on the air pump, inflate the air, and inflate the inside of the ablation circle 61 through the air guide hole 67. The gas will expand the multiple ablation circles 61 between the two connecting plates 62. When the ablation circle 61 is unfolded, the ablation circle 61 drives the connecting belt 63 to unfold. When the connecting belt 63 is unfolded, the storage belt 66 is unfolded synchronously. At this time, the first guide rod 64 slides inside the second guide rod 65. The first guide rod 64 and the second guide rod 65 play a role of supporting, guiding and positioning, so that the ablation circle 61 will not deflect when it is stretched. After the ablation circle 61 is unfolded, the edge of the connecting plate 62 is a corrugated structure, the connecting plate will unfold, and the connecting plate 62 does not block the pore, so that the pore is connected to the positioning mechanism 7, and the gas inside the pore is filled into the interior of the positioning mechanism 7. The positioning mechanism 7 stretches and is stuck in the interior of the positioning hole 57. When ablation is required, the ablation circle 61 is unfolded. When cells do not need to be ablated, the ablation circle 61 is received inside the cannula 41, and the received ablation circle 61 does not affect the process of the cannula 41 entering the esophagus. The extension of the ablation circle 61 is controlled by inflating the inside of the ablation circle 61. The unfolded ablation circle 61 will be located outside the cannula 41. After unfolding, the ablation circle 61 will fit on the cells, so that when ablating cells, there is no need to frequently adjust the position of the ablation circle 61, thereby reducing the difficulty of the operation and improving the efficiency of the operation.When the gas inside the air hole enters the inside of the outer retaining rod 72 through the conveying hole 74, the outer retaining rod 72 will move along the inner retaining rod 73. The movement of the outer retaining rod 72 will extend into the inside of the limiting hole. The outer retaining rod 72 inside the limiting hole is limited by the limiting hole and can only move backward and cannot move forward; the positioning of the outer retaining rod 72 is realized, and then it is limited when adjusting the movement of the rigid tube 51. By pressing the grip plate 35 with a finger, the movement of the grip plate 35 causes the moving rod 36 to drive the push rod 81 to flip. When the push rod 81 flips, it rotates around the positioning rod 83. The rear end of the rotating push rod 81 will abut against the guide rod 84, and the guide rod 84 will move. When the guide rod 84 moves, it will have a relative sliding with the push rod 81. When the guide rod 84 moves, it will drive the push plate 87 provided at its end to move. The movement of the push plate 87 will gradually approach the hardening tube 59. The movement of the hardening tube 59 drives the movement of the hose 56, and then the rigid tube 51 moves, realizing the movement of the ablation ring 61. Since the guide groove 86 is composed of a horizontal groove and an inclined groove, when the guide rod 84 moves, the guide rod 84 first moves from the horizontal groove and then enters the inside of the inclined groove, realizing that the push plate 87 first translates and then approaches the hardening tube 59, and pushing the hardening tube 59 to move, realizing the movement and adjustment of the medicine supply assembly 5 and the ablation assembly 6, facilitating the ablation of cancer cells by the ablation assembly 6 and the rapid medicine supply of the medicine supply assembly 5.
