Description

Technical Field

[0001] This application relates to the field of radiotherapy systems, and in particular to an automatic delivery mechanism for an operating handle in a proton and heavy ion therapy system. Background Technology

[0002] In proton or heavy ion therapy systems, the treatment area is a fixed indoor space containing equipment such as the treatment head and treatment bed. The patient receives treatment in this area, while the operator controls the movement of the equipment and performs other operations such as patient immobilization. A handheld control handle is typically placed within the treatment area for the operator's use. This handle is usually suspended from either side of the treatment area or from the ceiling.

[0003] like Figure 1 The treatment area includes a treatment head 12, a treatment bed 13, and an operating handle 14. In the figure, 11 is the floor of the treatment area.

[0004] In the prior art, the operating handle 14 is usually suspended on the walls on both sides of the treatment area; and since the distance between the two walls is usually more than 2m, the long cable of the operating handle may easily cause movement interference to the treatment area. Therefore, it is necessary to have two operating handles on the left and right sides that can be operated separately.

[0005] In another existing technology, the operating handle is also suspended from the ceiling by a non-powered, pull-and-follow rocker arm. However, because it is non-powered, it presents the problem that the operator is too far away from the handle to reach it.

[0006] In summary, the existing technology has the following problems:

[0007] (1) There is a conflict between left and right operation of the handle suspended on the wall and a problem that requires logical judgment to deal with the conflict. Solving this problem will increase the complexity of the control system.

[0008] (2) Due to the limited cable length, the handles that are suspended on the wall must be suspended on both the left and right sides, which increases the cost.

[0009] (3) When the handle is not in use, it must be hung back on the wall in a fixed position. Otherwise, if it is placed elsewhere, it may fall and be damaged.

[0010] (4) The non-powered handle suspended from the ceiling solves the above three problems, but since there is only one handle, when it is far from the operator's standing position, the operator must walk to the other side or go around the treatment bed to grab it, which is very inconvenient.

[0011] (5) The non-powered handle suspended from the ceiling also has a certain degree of downward extension and inward and outward movement, but its cable is also long and needs to be suspended from the ceiling cantilever at the same time, which makes the appearance messy and creates an uncomfortable treatment environment for patients on the treatment bed below.

[0012] Therefore, in order to solve the above-mentioned technical problems, a new technical solution is provided. Summary of the Invention

[0013] To address one of the aforementioned technical deficiencies, this application provides an automatic delivery mechanism for the operating handle of a proton and heavy ion therapy system.

[0014] According to a first aspect of the embodiments of this application, an automatic delivery mechanism for an operating handle of a proton and heavy ion therapy system is provided, comprising: a fixed base, a base rotating body, a base base plate, a camera module, an upper arm assembly, a lower arm assembly, a telescopic cable, and a control handle;

[0015] The base rotating body and the base base plate are both mounted on the fixed base. A camera module is installed below the fixed base. One end of the upper arm assembly is sleeved on the base rotating body, and the other end of the upper arm assembly is connected to the lower arm assembly. A cable winding mechanism is installed inside the lower arm assembly, and the cable winding mechanism is connected to a telescopic cable. The telescopic cable is connected to the control handle.

[0016] Furthermore, the base plate is a maintenance cover plate, and the base plate is movably connected to the fixed base.

[0017] Furthermore, a motor is installed inside the fixed base, and the motor is connected to the rotating body of the base through a drive assembly.

[0018] Furthermore, the camera module is one of the following models: OV5693, OV5640, IMX179, IMX335, OV2710, IMX258, and CanMv K210.

[0019] The beneficial technical effects of this application are as follows:

[0020] (1) Only one control handle is needed, which reduces the cost and complexity of the control system. It is independent and easy to install and arrange. It only needs one power cord to work.

[0021] (2) The movement is mainly performed in the upper part of the treatment area, avoiding interference with other indoor equipment such as treatment beds.

[0022] (3) Active delivery of control handles makes the operator’s work simpler, as they can obtain the control handle at any time without having to walk back and forth.

[0023] (4) It has a high degree of automation and does not require connection to an external control cabinet or any external processing equipment. It also has strong upgrade potential. It can use AI to detect the operator's gestures to determine whether a control handle is needed. If not, it can be stored on the ceiling; when needed, a single gesture is all it takes to lower the control handle to the operator's face. Attached Figure Description

[0036] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0037] This application provides an automatic delivery mechanism for the operating handle of a proton and heavy ion therapy system, such as... Figure 2 As shown, the automatic delivery mechanism 2 of the operating handle of this application is fixed to the ceiling of the treatment area, and its cantilever can rotate and extend to deliver the telescopic cable and control handle at the end to various positions in the treatment area.

[0038] like Figure 3 As shown, the main structure of this application includes: a fixed base 21, a base rotating body 22, a base base plate 23, a camera module 24, a large arm assembly 25, a small arm assembly 26, a telescopic cable 27, and a control handle 28.

[0039] The basic function of the fixed base 21 is to mount the base rotating body 22, the base plate 23, and the camera module 24 together and securely fix them to a specific position on the ceiling. Simultaneously, the fixed base 21 contains a motor, which can drive the base rotating body 22 to rotate around the circular axis of the fixed base 21 at a certain angle via a drive assembly; the range of this rotation angle is such that the entire device will not collide with the side walls or other indoor equipment. The rotational movement of the base rotating body 22 is described in [details omitted]. Figure 4 Meanwhile, a camera module 24 is connected to the bottom of the fixed base 21. The camera module 24 is controlled by a control system, model ESP32, which processes the information acquired by the camera to guide the movement of the cantilever. The base plate 23 below the fixed base 21 is a maintenance cover. After opening the base plate 23, basic maintenance operations can be performed on the inside of the equipment.

[0040] like Figure 6 As shown, the basic functions of the upper arm assembly 25 and the lower arm assembly 26 are to cooperate with each other to increase or decrease the radius that the handle can deliver.

[0041] like Figure 5 As shown, the boom assembly 25 is directly connected to the base rotating body 22, and the former rotates with the latter. The boom assembly 25 has a linear motion component inside, which can push the forearm assembly 26 in a linear motion.

[0042] like Figure 7As shown, the forearm assembly 26 also contains a cable winding mechanism that controls the cable's extension and retraction. Therefore, the forearm assembly 26, in conjunction with the telescopic cable 27, allows for adjustment of the height of the control handle 28.

[0043] like Figure 8 As shown, through the cooperation of the various motion components, this application can achieve the design objective of sending the control handle 28 to most of the treatment area.

[0044] In this application, the camera module 24, through camera lens selection and on-site debugging, can have its field of view set to cover the entire treatment area. The preferred model for the camera module is the CanMv K210 module.

[0045] The working principle of this application is:

[0046] like Figure 9 As shown, the camera module 24 at the bottom of the automatic delivery mechanism 2 of this application optically detects the treatment area 29, and the control device located in the fixed base 21 automatically confirms the position of the operator. Then, by controlling the movement of the base rotating body 22, the upper arm assembly 24 and the lower arm assembly 26, the design purpose of quickly and automatically delivering the control handle 28 to the position of the operator is achieved.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
