Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a medical device capable of continuous rotation. Background Art

[0002] In recent years, using X-rays, electron beams, and proton beams generated by medical accelerators (hereinafter simply referred to as accelerators) to treat malignant tumors is a relatively advanced radiotherapy plan. Key components in the rotating gantry of the accelerator generate a large amount of heat while generating X-rays. In order to maintain the normal operation of the key components, the excess heat in the key components needs to be removed.

[0003] Currently, most on the market use two "in - out" water pipes to exchange heat with an external water cooler, thereby realizing the thermal cycle of the equipment cooling water and ensuring the thermal stability of the key components. Specifically, the heat of the rotating part of the equipment is transferred out through water pipes. Such accelerators (hereinafter referred to as Type A) are limited by the length of the water pipes and can only adopt a "forward rotation + reverse rotation" motion mode, and cannot achieve continuous rotation. Accelerators using the "forward and reverse rotation" motion mode need to continuously rotate back and forth during operation, so they need to frequently accelerate and decelerate. During acceleration, deceleration, and commutation, radiotherapy cannot be performed, which greatly reduces the treatment efficiency. At the same time, frequent acceleration and deceleration not only have high requirements for the electric control, but also have high requirements for the treatment plan.

[0004] There are also a few accelerators that arrange the heat exchange device on the rotating gantry and are supplemented with several large fans to directly discharge the heat discharged from the key components generating X-rays into the treatment room, thereby maintaining the thermal stability of the equipment. This type of accelerator (hereinafter referred to as Type B) can achieve continuous rotation of the gantry due to being not limited by water pipes, improving the treatment efficiency and reducing the requirements for electric control. However, in order to transfer electricity and signals from the rotating gantry to the fixed part, such equipment needs to be equipped with a CT slip ring of a larger size; in addition, in order to achieve air cooling of the key components, a variety of devices such as a water storage tank, a water pump, pipelines, a heat exchanger, and a high-power fan need to be added to the rotating part. Such a configuration not only increases the production cost, but also increases the size and weight of the equipment main body, which is not convenient for the transportation and maintenance of the equipment.

[0005] In summary, existing accelerators do not provide a gantry layout that can continuously rotate and has a simple structure, resulting in problems of low treatment efficiency or high equipment cost. Summary of the Invention

[0006] The purpose of the embodiments of the present invention is to provide a medical device capable of continuous rotation to solve the problem in the prior art that it is difficult for accelerators to have both a simple gantry structure and the characteristic of continuous rotation of the gantry, resulting in problems of low treatment efficiency or high equipment cost.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0021] The terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0022] Next, in conjunction with Figures 1 to 9 , a continuously rotatable medical device 100 provided by the embodiments of the present invention will be described in detail through specific embodiments and their application scenarios.

[0023] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0024] The continuously rotatable medical device 100 according to an embodiment of the present invention includes a base 10, a rotating frame 20, a first slip ring body 30, a second slip ring body 31, and a support assembly 40.

[0025] Specifically, as Figure 1 and Figure 2As shown, the rotating frame 20 is connected to the base 10 to be supported by the base 10. The rotating frame 20 is rotatable relative to the base 10, and a first section of transmission medium 50 is fixed on the rotating frame 20; the first slip ring body 30 is fixed on the rotating frame 20, and the first slip ring body 30 makes a circular motion along with the rotating frame 20 during the rotation of the rotating frame 20; the second slip ring body 31 is pivotally connected to the first slip ring body 30, and the second slip ring body 31 makes a circular motion with a fixed orientation along with the rotating frame 20 during the rotation of the rotating frame 20; the support assembly 40 is connected to the second slip ring body 31 to support the second slip ring body 31 to always maintain a fixed orientation, and a second section of transmission medium 51 for communicating with the outside is fixed on the support assembly 40; wherein, one end of the first section of transmission medium 50 is connected to the first slip ring body 30, and one end of the second section of transmission medium 51 is connected to the second slip ring body 31. When the first slip ring body 30 rotates relative to the second slip ring body 31, one end of the first section of transmission medium 50 corresponds to and communicates with one end of the second section of transmission medium 51.

[0026] In other words, the continuously rotatable medical device 100 according to the embodiment of the present invention can be an accelerator. The accelerator adopts a small slip ring structure to realize the communication between the first section of transmission medium 50 on the frame and the second section of transmission medium 51 outside. The first slip ring body 30 makes a circular motion along with the rotating frame 20, and the first slip ring body 30 and the second slip ring body 31 can rotate relative to each other, for example, rotate like a bearing. While the second slip ring body 31 rotates along with the rotating frame 20, the second slip ring body 31 is always arranged in a fixed direction under the support of the support assembly 40, that is, in the space rectangular coordinate system, the second slip ring body 31 always maintains a fixed included angle and orientation (the motion form of the second slip ring body 31 is a directional circular motion, similar to: the windmill blade always faces one direction, for example, the windward direction, but the whole rotates around the axis). Specifically, Figures 4 to 9 It shows the forms of the first slip ring body 30 and the second slip ring body 31 at different positions during the rotation of the rotating frame 20 of a continuously rotatable medical device 100 along the arrow direction. Further, the present invention divides the transmission medium into two sections. The first section of transmission medium 50 is connected to the first slip ring body 30 and remains relatively stationary with respect to the first slip ring body 30. The second section of transmission medium 51 is connected to the second slip ring body 31 and remains relatively stationary with respect to the second slip ring body 31. When the rotating frame 20 rotates, the first slip ring body 30 and the second slip ring body 31 rotate relative to each other, and the first section of transmission medium 50 and the second section of transmission medium 51 communicate with each other, avoiding the transmission medium rotating along with the rotating frame 20 during the rotation of the rotating frame 20 and even getting entangled, realizing the communication of communication, power or cooling pipeline a, and facilitating the layout of relevant components of the rotating frame 20.

[0027] Thus, the continuously rotatable medical device 100 according to the embodiments of the present invention, compared with the existing medical accelerators, can not only achieve the continuous rotation of the rotating gantry, improve the treatment efficiency, but also facilitate the arrangement of the cables b for communication and power, the cooling pipelines a and their related accessories, and simplify the overall structure.

[0028] According to an embodiment of the present invention, the first transmission medium 50 and the second transmission medium 51 are respectively the pipeline a (the coolant in the pipeline a is generally cooling water, and can also be other coolants). Specifically, when the first transmission medium 50 and the second transmission medium 51 are respectively the pipeline a, it is mainly used to access the cooling water to perform water cooling on the key components of the accelerator, such as Figure 3 As shown, one first interface 301 on the first slip ring body 30 is used to access the cooling water inlet on the rotating gantry 20, and the other first interface 301 is used to access the cooling water outlet on the rotating gantry 20 ( Figure 3 only one first interface 301 is schematically shown in

[0029] ). The second interface 311 of the second slip ring body 31 is used to access the cooling water inlet on the support assembly 40 and the cooling water outlet on the support assembly 40. Among them, the cooling water on the support assembly 40 is connected to external equipment such as a water storage tank, a water pump, and a heat exchanger (referred to as refrigeration equipment) through the pipeline a. Since the continuously rotatable medical device 100 according to the embodiments of the present invention does not need to transfer the heat of the key components to the treatment room by carrying an air-cooled refrigeration device, it not only greatly improves the heat dissipation efficiency, but also reduces the load of the accelerator, making the accelerator body more lightweight and miniaturized. In addition, since the continuously rotatable medical device 100 according to the embodiments of the present invention avoids the restriction of the length of the cooling water pipe in the traditional structure during the rotation of the rotating gantry 20, the rotating gantry 20 can achieve continuous rotation without "forward and reverse rotation", greatly improving the treatment efficiency and reducing the electrical control requirements.

[0030] According to another embodiment of the present invention, the first section of transmission medium 50 and the second section of transmission medium 51 respectively include pipeline a and cable b. That is to say, the transfer of cooling water, signals, and electricity between the accelerator and the outside world is realized through the first slip ring body 30 and the second slip ring body 31, which can avoid complex pipeline settings, reduce the load of the equipment main body, and improve the treatment efficiency. It should be noted that the first section of transmission medium 50 and the second section of transmission medium 51 are not limited to the transmission of coolant, electricity, signals, optical fibers, etc.

[0031] Optionally, a continuously rotatable medical device 100 further includes a fixing bracket 60, and the fixing bracket 60 is arranged on the rotating frame 20 to fix the first slip ring body 30. It should be noted that the specific structures of the first slip ring body 30 and the second slip ring body 31 are not limited to the structures shown in the drawings in the embodiments of the present invention, and the structure of the fixing bracket 60 is also not limited to the structure shown in the drawings. During specific use, the structure of the fixing bracket 60 matching the first slip ring body 30 is selected according to the structure of the first slip ring body 30. For example, if the specific structural forms of the first slip ring body 30 and the second slip ring body 31 are interchanged, then the structure of the fixing bracket 60 needs to be adjusted accordingly to make it easy to assemble and install.

[0032] In an embodiment of the present invention, as Figure 1 shown, for the convenience of installation, the rotating frame 20 is installed on one side of the base 10, the fixing bracket 60 is arranged on the side of the rotating frame 20 away from the base 10, and the support assembly 40 is arranged on the side of the rotating frame 20 away from the base 10. In addition, as long as it is convenient for the cooperation of the first slip ring body 30 and the second slip ring body 31 and enables the first section of transmission medium 50 and the second section of transmission medium 51 to be connected, the fixing bracket 60 and the support assembly 40 can also be installed at other positions of the rotating frame 20. For example, they can be arranged on the left or right side of the rotating frame 20, etc., and are flexibly arranged according to the installation requirements, and are not limited to the layout mode in the embodiments of the present invention.

[0033] Preferably, the support assembly 40 includes a column 41 and a guide rod 42. Specifically, as Figure 1 and Figure 2 shown, the column 41 is fixed to one side of the rotating frame 20 and is spaced apart from the rotating frame 20. A fixing position is defined on the column 41, and the fixing position is located on the extension line of the central axis of the rotating frame 20; one end of the guide rod 42 is movably connected to the second slip ring body 31, and the other end is movably connected to the fixing position. The pipeline a and the cable b can be fixed on the guide rod 42 and the column 41 by bundling or other means.

[0034] Furthermore, one end of the guide rod 42 is movably connected to the second slip ring body 31 through a coupling 43, and the other end of the guide rod 42 is movably connected to the fixing position through a coupling 43, so as to ensure that the second slip ring body 31 always faces the fixed direction during the rotation of the rotating frame 20.

[0035] Optionally, the upright column 41 is fixed to one side of the rotary frame 20 and is relatively fixed to the base 10. A fixed position is defined on the upright column 41, and at least a part of the second transmission medium 51 is fixed to the upright column 41. Among them, the fixed position is not limited to being arranged on the extension line of the central axis of the rotary frame 20 and can be flexibly arranged at an appropriate position; one end of the guide rod 42 is movably connected to the second body 31 of the slip ring, and the other end is movably connected to the fixed position. At least another part of the second transmission medium 51 is fixed to the guide rod 42.

[0036] Further, one end of the guide rod 42 is movably connected to the second body 31 of the slip ring through a coupling, and the other end of the guide rod 42 is movably connected to the fixed position through a telescopic coupling (not shown, such as a spline coupling). The telescopic coupling can make the fixed point deviate from the extension line of the central axis of the rotary frame 20 by a certain distance, so as to make the layout more diversified. However, it can still meet the requirement that the second body 31 of the slip ring always faces the fixed direction during the rotation of the rotary frame 20 in the present application.

[0037] Since other structures of the continuously rotatable medical device 100 according to the embodiments of the present invention belong to the prior art, they will not be described in detail herein.

[0038] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the spirit and scope protected by the claims of the present invention, and all of them belong to the protection scope of the present invention.
