Description

Technical Field

[0001] The utility model relates to the technical field of treatment beds for breast cancer treatment equipment, in particular to a turning motion mechanism suitable for treatment beds for breast cancer treatment equipment. Background Art

[0002] The GammaPod stereotactic radiotherapy system for breast cancer, developed by Xcison in the United States, features a treatment couch that can be switched between upright and horizontal positions. This device incorporates a flipping mechanism that flips the couch from its initial upright position to its horizontal position. Sensors are installed at both the initial and final positions to detect position. The flipping mechanism also includes a mechanism for clamping the couch, with corresponding sensors used to determine if the clamping is secure. When the flipping mechanism flips the couch to the horizontal position, the vertical lift mechanism on the radiotherapy unit moves upward, supporting the couch. Sensors and positioning pins are installed at the top of the radiotherapy unit's lift mechanism. When the couch contacts the top of the lift mechanism and the guide pins are inserted into the pin holes, the flip mechanism's clamping mechanism allows for manual release, allowing the couch to rest fully on the lift mechanism. The flipping mechanism then returns the clamping mechanism to its initial retracted position. The X, Y, and Z axis motion mechanism on the radiotherapy unit then moves the couch, ensuring that the patient's breast lesion remains within the GammaPod's treatment target during treatment.

[0003] The flip mechanism is complex, and during docking, there's a risk of misalignment between the treatment couch and the main unit, preventing the couch from resting properly on the main unit's lifting mechanism, potentially leading to accidents. Because the couch and flip mechanism are separate components, there's a risk that if power is lost during treatment, the flip mechanism won't be able to move from its initial position to the horizontal position to reattach the couch to the main unit. This entire movement requires numerous inductive switches, sensors, and scales, leading to high production costs. Utility Model Content

[0004] The purpose of the present invention is to provide a flip motion mechanism for a treatment bed of breast cancer treatment equipment, so as to solve the problems in the above background technology that the existing technology is relatively complex, prone to accidents and has a relatively high production cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flip motion mechanism for a treatment couch in breast cancer treatment equipment, comprising a base, a T-shaped frame disposed on one side of the base, a flip motion assembly connected to the surface of the base, the flip motion assembly being used to drive the T-shaped frame to flip; a treatment couch disposed on the surface of the T-shaped frame, and a three-axis adjustment assembly enabling three-axis adjustment between the treatment couch and the T-shaped frame.

[0006] Preferably, the flip motion assembly includes an electric push rod, a cross arm, a flip plate and a vertical plate; two electric push rods are provided, and the two electric push rods are tilted and fixed on both sides of the base surface.

[0007] Preferably, two vertical plates are provided, and two electric push rods are fixedly connected to both sides of the base surface.

[0008] Preferably, a cross arm is hinged on the surface of the electric push rod, and a flip plate is hinged on the other end of the cross arm, and the output end of the electric push rod is hinged to the surface of one of the cross arms.

[0009] Preferably, the three-axis adjustment assembly includes a Z-axis linear slide, a Z-axis slider, an X-axis linear slide, a dual-axis slider and a Y-axis linear slide. The Z-axis linear slide is provided in two groups, and the two groups of dual-axis sliders are fixedly connected to the side of the T-frame by bolts.

[0010] Preferably, the surface of the Z-axis linear slide rail is slidably connected to a Z-axis slider, and the Z-axis slider is fixed to the surface of the flip plate.

[0011] Preferably, two sets of X-axis linear slides and two sets of Y-axis linear slides are provided, the two sets of X-axis linear slides are fixedly connected to the top of the T-frame, and the two sets of Y-axis linear slides are fixedly connected to the surface of the treatment bed; a dual-axis slider is slidably connected to the surface of the X-axis linear slide, and the top of the dual-axis slider and the Y-axis linear slide are slidably engaged with each other.

[0012] Compared with the prior art, the present invention has the following beneficial effects: the flip motion mechanism for the treatment bed of breast cancer treatment equipment flips the treatment bed by providing a flip motion assembly driven by a T-shaped frame. When the flip motion assembly is in operation, an electric push rod is used as the flipping power, and a cross arm is used to achieve a mechanical limit from the tilted position to the horizontal position. When the treatment bed reaches the horizontal position, the push rod stops working and the cross arm also reaches the limited position. Due to the rigidity of the cross arm, even if the push rod does not stop working, the treatment bed will not continue to flip, thus ensuring safety.

[0013] The three-axis adjustment assembly simultaneously enables movement in the X, Y, and Z axes, ensuring that the treatment bed can achieve three-dimensional movement after being flipped to the horizontal position. This allows the patient's breast lesion to be consistently positioned within the treatment target area of ​​the main unit. This eliminates the need for an X, Y, and Z axis motion mechanism on the main unit, reducing the difficulty of installing and debugging the main unit. The present invention can be installed and debugged independently of the main unit, significantly reducing the time and effort required for installation and debugging, and making it easier for ordinary skilled workers to complete installation. Therefore, the flip mechanism described in the present invention integrates the treatment bed and the flip mechanism into one unit. The treatment bed only needs to be screwed onto the linear guide rail, eliminating the need for repeated clamping and loosening of the treatment bed and flip mechanism. This eliminates the need for complex clamping mechanisms, reduces material usage, and reduces processing and assembly difficulties, significantly lowering production costs.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The utility model provides a structure of a flip motion mechanism for a treatment bed of breast cancer treatment equipment. Figure 1 as well as Figure 3 As shown, it includes a base 1, a T-shaped frame 2 is provided on one side of the base 1, and a flip motion component 4 is connected to the surface of the base 1, which is used to drive the T-shaped frame 2 to flip, and the flip motion component 4 includes an electric push rod 41, a cross arm 42, a flip plate 43 and a vertical plate 44; there are two electric push rods 41, which are obliquely fixed on both sides of the surface of the base 1, and there are two vertical plates 44, which are fixedly connected to both sides of the surface of the base 1, and the surface of the electric push rod 41 is hinged with a cross arm 42, and the other end of the cross arm 42 is hinged with a flip plate 43, and the output end of the electric push rod 41 is hinged to the surface of one of the cross arms 42; a treatment bed 3 is provided on the surface of the T-shaped frame 2.

[0021] During implementation, an electric push rod 41 is used as the turning power, and a cross arm 42 is used to achieve mechanical limit from the tilted position to the horizontal position. When the treatment bed 3 reaches the horizontal position, the push rod stops working and the cross arm 42 also reaches the limited position. Due to the rigidity of the cross arm 42, even if the push rod does not stop working, the treatment bed 3 will not continue to turn over, ensuring safety.

[0022] Furthermore, if Figure 2 、 Figure 3 as well as Figure 4As shown, the treatment bed 3 and the T-frame 2 are adjusted in three axes through a three-axis adjustment assembly 5, which includes a Z-axis linear slide 51, a Z-axis slider 52, an X-axis linear slide 53, a dual-axis slider 54 and a Y-axis linear slide 55. Two groups of Z-axis linear slides 51 are provided, and the two groups of dual-axis sliders 54 are fixedly connected to the side of the T-frame 2 by bolts. The surface of the Z-axis linear slide 51 is slidably connected to the Z-axis slider 52, and the Z-axis slider 52 is fixed to the surface of the flip plate 43. Two groups of X-axis linear slides 53 and Y-axis linear slides 55 are each provided. Two groups of X-axis linear slides 53 are fixedly connected to the top of the T-frame 2, and two groups of Y-axis linear slides 55 are fixedly connected to the surface of the treatment bed 3; the surface of the X-axis linear slide 53 is slidably connected to the dual-axis slider 54, and the top of the dual-axis slider 54 and the Y-axis linear slide 55 slide in cooperation with each other.

[0023] During implementation, the three-axis adjustment component 5 is used to achieve movement in the three directions of XYZ axes, ensuring that the treatment bed 3 can achieve movement in the three directions of XYZ after being flipped to the horizontal position. According to treatment needs, the corresponding slide rails and sliders can be slid and fixed by bolts after sliding, so that the patient's breast lesion is always adjusted to be in the treatment target area of ​​the host. There is no need to assemble the XYZ axis movement mechanism on the treatment host, which reduces the difficulty of installation and debugging of the treatment host. The utility model can be installed and debugged separately without relying on the treatment host, which greatly saves the time and difficulty of installation and debugging, and is easier for ordinary technical workers to complete the installation.

[0024] Working Principle: When in use, the present invention flips the treatment bed 3 through the flip motion assembly 4 driven by the T-shaped frame 2. When the flip motion assembly 4 is implemented, the electric push rod 41 is used as the flipping power, and the cross arm 42 is used to achieve mechanical limit from the inclined position to the horizontal position. When the treatment bed 3 reaches the horizontal position, the push rod stops working and the cross arm 42 also reaches the limited position. Due to the rigidity of the cross arm 42, even if the push rod does not stop working, the treatment bed 3 will not continue to flip, thereby ensuring safety.

[0025] The present invention realizes the flipping function and at the same time realizes the movement in the three directions of XYZ axis by using the three-axis adjustment component 5, so as to ensure that the treatment bed 3 can realize the movement in the three directions of XYZ axis after being flipped to the horizontal position. According to the treatment needs, the corresponding slide rails and sliders can be slid and fixed by bolts after sliding, so as to adjust the patient's breast lesion to always be in the treatment target area of ​​the host. There is no need to assemble the XYZ axis movement mechanism on the treatment host, which reduces the difficulty of installing and debugging the treatment host. The present invention can be installed and debugged independently without relying on the treatment host, which greatly saves the time and difficulty of installation and debugging, and is easier for ordinary technical workers to complete the installation.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
