Description

Technical Field

[0001] The utility model belongs to the technical field of positioning devices, and in particular relates to a tumor radiotherapy positioning device. Background Art

[0002] Tumor radiotherapy, abbreviated as radiotherapy, is a method of treating cancer using radiation. During radiotherapy, the patient needs to lie on a radiotherapy bed. In order to ensure the accuracy of radiotherapy, ensure that the rays can accurately irradiate the tumor location, and reduce damage to surrounding tissues, the patient needs to be fixed. In the existing technology, the patient is generally fixed by means of molds, straps, support plates, etc., but this fixation method has certain limitations and disadvantages, such as poor fixation stability and inconvenient adjustment for patients of different body shapes. For this reason, we propose a tumor radiotherapy positioning device. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a tumor radiotherapy positioning device, which can fix the patient's waist comprehensively, evenly and closely, automatically adapt to the patient's waist body curve, and have the function of adjusting the patient's leg shape, so as to facilitate adjustment for patients of different body shapes and ensure the stability of the patient's position fixation.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a tumor radiotherapy positioning device comprises a treatment bed, a first adjustment slide rail and a second adjustment slide rail are installed on the side of the treatment bed, a first slider and a second slider are slidably installed inside the first adjustment slide rail and the second adjustment slide rail respectively, a support arm is installed on the side of the first slider, a first electric telescopic rod is installed on the top of the support arm, a rotation adjustment seat is installed on the top of the first electric telescopic rod, a second motor is installed on the side of the rotation adjustment seat, a rotating shaft is rotatably installed on the other side of the rotation adjustment seat, an output shaft of the second motor is connected to the rotating shaft, one end of the rotating shaft is connected to a waist fixing seat, a telescopic rod array is provided on one side of the waist fixing seat, a support frame is installed on the side of the second slider, a third electric telescopic rod is installed on one side of the support frame, a leg fixing device is installed on one end of the third electric telescopic rod, and a headrest is installed on the top of the treatment bed.

[0005] The beneficial effects of the utility model are as follows: the second electric telescopic rods of the device are evenly distributed on the sides of the waist fixing seat in an array, so the patient's waist can be fixed comprehensively, evenly and with high fit, and each second electric telescopic rod drives the positioning ball to move toward the patient's body. The positioning ball is made of a rubber ball. When the positioning ball contacts the patient, the pressure sensor inside the positioning ball is subjected to pressure and transmits a signal to the operating device, and the operating device automatically controls the second electric telescopic rod where the pressure sensor is located to stop extending. Since the patient's waist curve is not straight, each independently adjustable second electric telescopic rod can fix each position of the patient's waist with the positioning ball, thereby improving the stability of the patient's waist fixation. When the patient adopts a side-lying position, the first electric telescopic rod can be controlled to drive the rotating adjustment seat to rise, and the second motor drives the rotating shaft to rotate together with the waist fixing seat, so that the waist fixing seat is converted to a state that is wide up and down and narrow front and back. Therefore, when the second electric telescopic rod drives the positioning ball to clamp and support the patient, it can fit the patient's abdomen and back in a larger area and more points, thereby ensuring the stability of the patient's body position fixation.

[0006] The patient's legs pass through the inner side of the leg fixing device, and the third electric telescopic rod is controlled to perform telescopic adjustment to drive the lower fixing frame on the left and the lower fixing frame on the right to move toward or away from each other, thereby adjusting the actual width of the leg fixing device according to the patient's leg width. During the adjustment process, the telescopic plug plate is inserted into the through slot, so that the left and right groups of lower fixing frames are always kept in a state of mutual support, and the operation of the fourth electric telescopic rod can drive the upper fixing frame to rise and fall to adapt to the patient's leg height, and the patient's legs are stably clamped by the adjustable left and right groups of lower fixing frames and upper fixing frames.

[0007] To adjust the front and rear horizontal position of the waist and leg restraints:

[0008] As a further improvement of the above technical solution: a first motor is installed at one end of the first adjusting slide rail and one end of the second adjusting slide rail, the output shaft of the first motor is connected to the transmission screw, and the first slider and the second slider are threadedly connected to the transmission screw.

[0009] The beneficial effect of this improvement is that the first motor drives the transmission screw to rotate, and the transmission screw can drive the first slider and the second slider to slide, thereby adjusting the front and rear horizontal positions of the waist fixing seat and the leg fixing device.

[0010] To improve the stability of the patient's lumbar fixation:

[0011] As a further improvement of the above technical solution: the telescopic rod array includes uniformly arranged second electric telescopic rods, one end of the second electric telescopic rod is installed with a positioning ball, and a pressure sensor is installed inside the positioning ball.

[0012] The beneficial effects of this improvement are as follows: the second electric telescopic rod is controlled to extend according to the patient's body shape, and the second electric telescopic rods are evenly distributed on the sides of the waist fixing seat in an array, so the patient's waist can be fixed comprehensively, evenly and with a high degree of fit, and each second electric telescopic rod drives a positioning ball to move toward the patient's body. The positioning ball is made of a rubber ball. When the positioning ball contacts the patient, the pressure sensor inside the positioning ball is subjected to pressure and transmits a signal to the operating device, and the operating device automatically controls the second electric telescopic rod where the pressure sensor is located to stop extending. Since the patient's waist curve is not straight, each independently adjustable second electric telescopic rod can fix the patient's waist at various positions with the positioning ball, thereby improving the stability of the patient's waist fixation.

[0013] To control the operation of this device:

[0014] As a further improvement of the above technical solution: an operating device is installed on the side of the treatment bed.

[0015] The beneficial effect of this improvement is that a touch screen is installed on the operating device, and a processor module is installed inside the operating device to control the operation of the device.

[0016] To adjust the leg restraint to the size of the patient's legs:

[0017] As a further improvement of the above technical solution: one end of the leg fixing device is connected to the lower fixing frame, an upper fixing frame is provided above the lower fixing frame, the side surfaces of the lower fixing frame and the upper fixing frame are provided with connecting plates, and a fourth electric telescopic rod is provided between the connecting plates.

[0018] The beneficial effect of this improvement is that the left lower fixing frame and the right lower fixing frame can be driven to move toward or away from each other by controlling the third electric telescopic rod to perform telescopic adjustment, so as to adjust the actual width of the leg fixing device according to the patient's leg width. During the adjustment process, the telescopic plug plate is inserted into the through slot, so that the left and right groups of lower fixing frames are always kept in a state of mutual support, and the operation of the fourth electric telescopic rod can drive the upper fixing frame to move up and down to adapt to the patient's leg height.

[0019] In order to ensure that the left and right sets of lower fixing frames always support each other:

[0020] As a further improvement of the above technical solution: a through slot is provided between the two side surfaces of one group of lower fixing frames, and a telescopic plug plate is connected to one side of the other group of lower fixing frames, and the through slot and the telescopic plug plate are inserted and connected.

[0021] The beneficial effect of this improvement is that during the adjustment process of the leg fixing device, the telescopic plug plate is inserted into the through slot, so that the left and right sets of lower fixing frames are always kept in a state of mutual support.

[0022] To enhance patient comfort and pressure delivery:

[0023] As a further improvement of the above technical solution: the positioning ball is made of a rubber ball.

[0024] The beneficial effects of this improvement are as follows: on the one hand, the rubber ball can improve the comfort of the patient when in contact with it, and on the other hand, it can be deformed due to the squeezing of the patient's body and the second electric telescopic rod, and transmit the pressure to the pressure sensor to detect whether the second electric telescopic rod is fully extended or not.

[0034] The second electric telescopic rods 16 of the device are evenly distributed on the side of the waist fixing seat 14 in an array, so the patient's waist can be fixed comprehensively, evenly and with high fit. Each second electric telescopic rod 16 drives the positioning ball 17 to move toward the patient's body. The positioning ball 17 is made of a rubber ball. When the positioning ball 17 contacts the patient, the pressure sensor 28 inside the positioning ball 17 is pressurized and transmits a signal to the operating device 2. The operating device 2 automatically controls the second electric telescopic rod 16 where the pressure sensor 28 is located to stop extending. Since the patient's waist curve is not straight, each second electric telescopic rod 16 can be independently The second electric telescopic rod 16 that can be adjusted vertically can fix the positioning ball 17 at all positions of the patient's waist, thereby improving the stability of the patient's waist fixation. When the patient adopts a side-lying position, the first electric telescopic rod 10 can be controlled to drive the rotating adjustment seat 11 to rise, and the second motor 12 can drive the rotating shaft 13 together with the waist fixing seat 14 to rotate, so that the waist fixing seat 14 is converted to a state that is wider up and down and narrower front and back.

The second electric telescopic rods 16 are evenly distributed in an array on the side of the waist fixing seat 14, so the patient's waist can be fixed comprehensively, evenly and with a high degree of fit. Each second electric telescopic rod 16 drives the positioning ball 17 to move toward the patient's body. The positioning ball 17 is made of a rubber ball. When the positioning ball 17 contacts the patient, the pressure sensor 28 inside the positioning ball 17 is subjected to pressure and transmits a signal to the operating device 2. The operating device 2 automatically controls the second electric telescopic rod 16 where the pressure sensor 28 is located to stop extending. Since the patient's waist curve is not straight, each independently adjustable second electric telescopic rod 16 can fix the positioning ball 17 at each position of the patient's waist, thereby improving the stability of the patient's waist fixation.

[0040] An operating device 2 is installed on the side of the treatment bed 1 .

[0041] A touch screen is installed on the operating device 2, and a processor module is installed inside the operating device 2 for controlling the operation of the device.
