Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 3 As shown, this embodiment proposes a tumor surgical radiation ablation device, including a device body 1, a servo motor 2 is fixedly connected to the top of the inner cavity of the device body 1, a support plate 3 is fixedly connected to the inside of the device body 1, the servo motor 2 is fixedly connected to a reciprocating screw 4 through an output shaft, a bearing seat 5 is provided on the outside of the reciprocating screw 4, the reciprocating screw 4 and the bearing seat 5 are connected by a ball nut pair, a moving platform 6 is fixedly connected to the outer side of the bearing seat 5, a servo motor 2 7 is fixedly connected to one side of the inner cavity wall of the moving platform 6, a support plate 2 8 is fixedly connected to the inside of the moving platform 6, the servo motor 27 is fixedly connected to a reciprocating screw 2 9 through the output shaft, a bearing seat 2 10 is provided on the outside of the reciprocating screw 2 9, the reciprocating screw 2 9 and the bearing seat 2 10 are connected by a ball nut pair, and a tumor ablation device body 11 is fixedly connected to the outer side of the bearing seat 2 10.

[0027] In this embodiment, the output shaft of the servo motor 2 extends to the interior of the support plate 3 and is connected to the support plate 3 through a bearing, and the top of the reciprocating screw rod 4 extends to the interior of the support plate 3 and is connected to the support plate 3 through a bearing, which makes it easy for the servo motor 2 to drive the reciprocating screw rod 4 to rotate through the output shaft.

[0028] In this embodiment, the output shaft of the servo motor 27 extends to the interior of the support plate 28 and is connected to the support plate 28 through a bearing. One end of the reciprocating screw rod 29 extends to the interior of the support plate 28 and is connected to the support plate 28 through a bearing, which makes it convenient for the servo motor 27 to drive the reciprocating screw rod 29 to rotate through the output shaft.

[0029] In this embodiment, the bottom of the reciprocating screw 1 4 is connected to the bottom of the inner cavity of the device body 1 through a bearing, and one end of the reciprocating screw 2 9 is connected to one side of the inner cavity wall of the movable platform 6 through a bearing, which can facilitate the rotation of the reciprocating screw 1 4 and the reciprocating screw 2 9 inside the device body 1 and the movable platform 6 respectively.

[0030] When a patient needs to undergo stereotactic radiotherapy for tumor ablation, the medical staff first connects the servo motor 2 inside the device body 1. After the servo motor 2 is energized, it drives the reciprocating screw 4 to rotate through the output shaft. When the reciprocating screw 4 rotates, it drives the bearing seat 5 to move up and down. When the bearing seat 5 moves up and down, it drives the movable platform 6 to move up and down. When the movable platform 6 moves up and down, it drives the bearing seat 2 10 to move up and down. When the bearing seat 2 10 moves up and down, it drives the tumor ablation device body 11 to move up and down. When the tumor ablation device body 11 moves to the appropriate height, the tumor ablation device body 11 can be stopped by controlling the servo motor 2. Then, the servo motor 2 7 is energized and connected. After the servo motor 2 7 is energized, it will The support plate 28 is driven to rotate, and the rotation of the support plate 28 will drive the bearing seat 2 10 to move left and right. The movement of the bearing seat 2 10 will drive the tumor ablation device body 11 to move left and right.

It can also avoid manual adjustment of the device by medical staff, making the operation of the device more time-saving and labor-saving, thereby reducing the workload of medical staff.

[0031] Example 2

[0032] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the bottom of the device body 1 is fixedly connected to a base 12, and the inside of the base 12 is connected with four screws 13 through threads.

[0033] In this embodiment, the tops of the four screws 13 are fixedly connected to a rotating rod 14 , and the bottoms of the four screws 13 are connected to a support seat 15 through a bearing, so that the four screws 13 can be driven to rotate by twisting the rotating rod 14 .

[0034] In this embodiment, four fixing rods 16 are fixedly connected to the bottom of the base 12, and the bottoms of the four fixing rods 16 are connected to universal wheels 17 through bearings, which can drive the entire device to move when the four universal wheels 17 are in contact with the ground.

[0035] In this embodiment, the four support bases 15 are in contact with the ground, and the four screws 13 are symmetrically distributed in pairs, so that the four support bases 15 can lift and fix the entire device.

[0036] When the entire device needs to be moved, the staff first rotates the four rotating rods 14. When the four rotating rods 14 rotate, the four screws 13 will be driven to rotate at the same time. When the four screws 13 are rotated, the four support seats 15 will be driven to move upward. When the four support seats 15 move to the bottom of the base 12, they stop rotating. At this time, the contact force of the four support seats 15 with the ground will disappear, and the four universal wheels 17 will contact the ground. At this time, the medical staff can move the entire device by pushing the device body 1. When it moves to the designated position, the medical staff rotates the four rotating rods 14 in the opposite direction. When the four rotating rods 14 rotate in the opposite direction, the four screws 13 will be driven to rotate in the opposite direction. When the four screws 13 rotate in the opposite direction, the support seats 15 will move downward. When the four support seats 15 move to contact the ground, the entire device will be lifted up and fixed. The above device can be used to quickly and conveniently move the entire device at any time, thereby improving the flexibility of the device.
