Description

[0001] The present invention is "The application date is: February 14, 2020; the application number is: 2020100920733; the name of the invention is: "For: an unlocking device" Divisional application. Technical Field

[0002] The present invention relates to the technical field of radiotherapy equipment, and in particular to an unlocking device for a body frame plate. Background Art

[0003] Radiotherapy (abbreviated as RT) is currently one of the main means of treating malignant tumors; domestic radiotherapy as a whole has now entered the stage of precision treatment. During the process of precision radiotherapy, keeping the patient's position fixed is the key to precision treatment.

[0004] In the prior art, a set of fixing devices is usually used to fix the radiotherapy patient, and the fixing device includes: a thermoplastic film (or positioning film) and a body frame plate (or positioning plate), wherein the body frame plate is a flat plate, and a plurality of positioning holes are respectively arranged at the edge of the body frame plate, and side strips are respectively arranged at the edges of both sides of the thermoplastic film, and fixing holes are respectively arranged at the positions of the side strips corresponding to the positioning holes, and the fixing holes are respectively provided with a latch and a pin sleeve. The specific structure of the latch and the pin sleeve can be referred to Chinese patent CN 201611073892 or CN 201621293392; When using the fixation device to fix the patient, it is necessary to first place the body frame board horizontally, then let the patient lie flat on the body frame board, and then cover the patient with a thermoplastic film, and put the pin sleeves on the thermoplastic film into the corresponding positioning holes respectively. Finally, the medical staff manually presses the latch, and the latch moves relative to the pin sleeve, so that the lower end of the latch extends out of the pin sleeve and squeezes the pin sleeve. The pin sleeve is squeezed and expands, thereby clamping the side wall of the positioning hole to achieve the locking function. Figure 1 , Attachment Figure 2 and attached Figure 3 As shown; after use, the medical staff manually pulls out the pins in each positioning hole to unlock the device, allowing the patient to move and the thermoplastic film to be removed from the body frame; for patients who need radiotherapy, whether in the early stage of radiotherapy, such as thermoplastic film production, positioning CT scanning, position confirmation, etc., or in the process of receiving radiotherapy, the medical staff need to use the fixation device to fix the patient in order to achieve precise treatment.

[0005] After the traditional fixing device has fixed the patient, it can only be unlocked by medical staff, and the patient cannot unlock it by himself, which makes the patient prone to suffocation, aspiration pneumonia, and even death when he has symptoms such as nausea and vomiting. In order to solve this problem, some unlocking devices or fixing devices with unlocking functions are disclosed in the prior art, such as Chinese patents CN 109125957A, CN 109453471A, etc., so that patients can unlock the door by themselves in an emergency, thereby improving safety; however, existing unlocking devices usually have the problem of poor universality, because existing unlocking devices need to be matched with body frame plates of corresponding models and sizes (when the models and sizes are different, the positions and numbers of the positioning holes on the body frame plates are usually different) to accurately align with the positioning holes on the body frame plates, and then to achieve the unlocking function, resulting in poor universality; when the body frame plates used in the hospital have multiple models or sizes, corresponding unlocking devices need to be set up respectively, resulting in high costs; in addition, for body frame plates of the same model or size, the position of the unlocking pin required is different depending on the different radiotherapy sites of the patients (such as there is a big difference between head and neck radiotherapy patients and chest radiotherapy patients), which makes the existing unlocking devices inapplicable.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0058] Example 1

[0059] like Figure 4-Figure 15 As shown, in this embodiment, an unlocking device for a body frame plate 600 is provided, including a plurality of unlocking terminals 100 and flexible transmission components, wherein the unlocking terminal 100 includes a support portion 101 and an unlocking component 503, the unlocking component 503 is arranged on the support portion 101, and the flexible transmission components are respectively connected to each support portion 101 for transmitting unlocking power, and the unlocking components 503 are respectively used to move relative to the support portion 101 under the drive of the unlocking power, and squeeze the pin 614 in the positioning hole 610 through the said action to drive the pin 614 to unlock, thereby realizing the unlocking function.

[0060] In this embodiment, the body frame plate 600 may be a body frame plate 600 commonly used in the prior art, for example, Figure 1-Figure 3 As shown, nine positioning holes 610 are provided on the body frame plate 600; when performing chest radiotherapy, usually only positioning hole 1 601, positioning hole 2 602, positioning hole 3 603, and positioning hole 4 604 are used, and when performing head and neck radiotherapy, usually only positioning hole 5 605, positioning hole 606, positioning hole 7 607, positioning hole 8 608, and positioning hole 9 609 are used, and the distribution positions of the positioning holes 610 are often different between different types of body frame plates 600; and by using the unlocking device provided in this embodiment, each unlocking terminal 100 can be respectively matched with the positioning hole 610 to be unlocked, so that it is applicable to different types of body frame plates 600 and also applicable to positioning holes 610 at different positions, and has strong versatility.

[0061] To achieve unlocking, each unlocking end 100 needs to be placed under the frame plate 600. Therefore, as a preferred embodiment, the support portion 101 includes an upper support surface 106, a lower support surface 107 and a side surface, and the upper support surface 106 and the lower support surface 107 are parallel to each other so as to stably support the frame plate 600. The upper support surface 106 is provided with a lock hole 102. The unlocking component 503 is provided in the lock hole 102 and is used to extend out of the lock hole 102 under the driving of the unlocking power so as to contact and squeeze the latch 614 in the corresponding positioning hole 610 above the lock hole 102, so that the latch 614 moves relative to the pin sleeve 613 to achieve the purpose of unlocking; the flexible transmission components are respectively connected to the side surfaces of each support portion 101, such as Figure 4 , Figure 5 As shown, it can be understood that the support portion 101 has various implementations. Preferably, the support portion 101 can preferably adopt a cylindrical structure or a square structure.

[0062] It can be understood that the support part 101 is made of non-metallic materials, such as plastic, carbon fiber, polymer materials, etc.

[0063] To achieve synchronous unlocking, in a linkage solution, the flexible transmission component includes a flexible main transmission member 103, and each support portion 101 is connected in series to the main transmission member 103, such as Figure 4 , 5 As shown; by connecting in series, the synchronous action of each unlocking component 503 can be achieved, and the synchronous unlocking function can be realized; and by utilizing the flexibility of the main transmission member 103, the position of each unlocking terminal 100 can be flexibly placed as needed, so as to correspond to the corresponding latch 614 and the positioning hole 610, so as to match body plates 600 of different models and sizes, meet different unlocking requirements, etc., which can significantly improve the versatility.

[0064] To realize gas / liquid transmission, in this embodiment, the main transmission member 103 can be a hose or include at least one section of a hose, and the main transmission member 103 is filled with gas and / or liquid for transmission, so that gas and / or liquid can be used for transmission, such as Figure 4 As shown, when in use, one end of the main transmission member 103 is connected to the booster, and the booster can be a booster pump, a cylinder, etc., so as to provide unlocking power, and the patient can hold the switch of the booster, turn on the switch in an emergency, start the booster, and realize the unlocking function; to facilitate the connection of the booster, one end of the main transmission member 103 is provided with a connector for connecting to the booster, and the connector can be an existing connector for assembly.

[0065] In order to improve the gas / liquid transmission unlocking, in this embodiment, the support part 101 is provided with a flow channel 104, the flow channel 104 is connected with the main transmission member 103 and the lock hole 102, and the flow channel 104 and the lock hole 102 are isolated by an unlocking component 503, and the unlocking component 503 is used to expand / contract along the length direction of the lock hole 102 under the pressure of the gas and / or liquid in the flow channel 104. There are many implementations of the unlocking component 503, as an example, Figure 6 and Figure 7 As shown, the unlocking component 503 includes a telescopic tube 105, which is arranged in the lock hole 102, one end of the telescopic tube 105 is connected to the flow channel 104, and the other end is provided with a hard sealing plate, and the telescopic tube 105 is used to extend under the action of pressure; when unlocking is required, the pressure in the flow channel 104 increases, and the telescopic tube 105 extends along the length direction of the lock hole 102 under the action of pressure, and extends out of the lock hole 102, so that the hard sealing plate at the end of the telescopic tube 105 can squeeze and drive the bolt 614 to move, as shown in FIG. Fig.13 As shown, the unlocking function is realized.

[0066] like Figure 6 and Figure 7 As shown, as a preference, the telescopic tube 105 can be a corrugated tube made of plastic or rubber, which can not only realize the telescopic function but also has a simple structure and low cost.

[0067] As another optional solution, the unlocking component 503 includes an elastic membrane, such as a rubber film, arranged between the flow channel 104 and the lock hole 102. The elastic membrane is used to expand along the lock hole 102 under the action of internal pressure. The elastic membrane is expanded by increasing the pressure. The expanded elastic membrane can extend out of the lock hole 102 and squeeze the upper latch 614, which can also achieve the purpose of unlocking. It will not be repeated here.

[0068] In order to facilitate the alignment with the positioning hole 610 on the frame plate 600 so as to realize the unlocking function, further, a positioning portion is included, which is arranged on the support portion 101 and is used to align the locking hole 102 with the positioning hole 610 of the frame plate 600; when the unlocking terminal 100 is actually installed, the positioning portion can be used to accurately and quickly determine the position of the unlocking terminal 100, so that the locking hole 102 in the unlocking terminal 100 can be just aligned with the positioning hole 610 of the frame plate 600 to realize the unlocking function.

[0069] As a preferred embodiment, the positioning portion includes a positioning protrusion 111 disposed at the locking hole 102, and the positioning protrusion 111 is used to be inserted into the corresponding positioning hole 610, so that the center line of the locking hole 102 is coaxial with the center line of the positioning hole 610, such as Figure 8 and Fig. 9When setting the unlocking terminal 100, by inserting the positioning protrusion 111 into the corresponding positioning hole 610, it can be ensured that the center line of the locking hole 102 is coaxial with the center line of the positioning hole 610, so that the locking hole 102 is aligned with the positioning hole 610, which is not only convenient and efficient in alignment and positioning, but also can ensure the smooth realization of the unlocking function.

[0070] There are many implementations of the positioning protrusion 111. In a preferred implementation, the positioning protrusion 111 is a cylindrical structure, such as Figure 8 and Fig.10 As shown, the outer diameter of the positioning protrusion 111 is smaller than (slightly smaller than) the inner diameter of the positioning hole 610, so that the positioning protrusion 111 can be inserted into the corresponding positioning hole 610 to achieve alignment.

[0071] In another embodiment, the positioning protrusion 111 includes at least two positioning columns 112 distributed along the circumference of the lock hole 102, and the outer diameter of the base circle surrounded by each positioning column 112 is smaller than the inner diameter of the positioning hole 610. So that the positioning protrusion 111 can be inserted into the corresponding positioning hole 610 to achieve alignment; the number of positioning columns 112 can be determined according to actual needs, for example, Fig. 9 As shown, the positioning protrusion 111 includes four positioning columns 112 evenly distributed along the circumferential direction of the locking hole 102. The outer diameter of the base circle surrounded by each positioning column 112 is smaller than the inner diameter of the positioning hole 610, so as to achieve the positioning and alignment functions.
