Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multifunctional fixation device for positioning and setting of tumor radiotherapy. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, and γ rays produced by radioactive isotopes and X-rays, electron beams, proton beams, and other particle beams produced by various X-ray therapy machines or accelerators. About 70% of cancer patients require radiotherapy during the treatment of cancer, and about 40% of cancers can be cured by radiotherapy. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent, and it has become one of the main means of treating malignant tumors.

[0003] After searching, it was found that the prior art publication number is CN117427287A, which discloses a special radiotherapy fixation device for tumor radiotherapy departments, which solves the problem that the conventional radiotherapy fixation device is inconvenient to adjust the position of the leg fixing structure, resulting in overlapping of the treatment area and the binding area, affecting the leg treatment. By movably installing a storage cover and an annular telescopic assembly on one side of the upper lying plate, and arranging multiple winding drums inside the storage cover, the binding belt inside the winding drum is movably connected to one side of the arc-shaped docking block through a clamping block, and the arc-shaped docking block is movably connected to the telescopic end of the annular telescopic assembly. This solution disassembles the binding belt above the patient's treatment area to expose the area to be treated, thereby achieving effective fixation of the legs while also making adaptive adjustments to the treatment area of ​​the legs to expose them for convenient radiotherapy.

[0004] Therefore, based on the above search and combined with existing technologies, when performing tumor radiotherapy on patients, since the location of the tumor in the patient's limbs is in a complex position, during radiotherapy, it is necessary to make micro-adjustments to the patient's posture so as to achieve the best treatment effect. When fixing the patient's limbs, it is also necessary to ensure that the patient is in a comfortable position to prevent the discomfort caused by maintaining the same posture for a long time. The above scheme does not have a substantial solution to this problem. For this reason, we propose a multifunctional fixation device for tumor radiotherapy positioning. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional fixation device for positioning and setting of tumor radiotherapy to solve the problems raised in the above-mentioned background technology.

A ball rod is passed through the inner end of the movable cylinder, and a support block is clamped on the upper end of the ball rod. The upper end of the support block abuts against the bottom end of the cushion. Under the action of the cushion, the patient's experience during the treatment is more comfortable, and the patient's mental stress is relieved.

[0008] As a further solution of the present invention, a reversing tube is passed through the inner end of the bidirectional tube holder, and the end of the movable cylinder close to the bidirectional tube holder is sleeved on the upper end of the reversing tube, the ball rod and the reversing tube are on the same axis, a driving rod is fixedly installed at the bottom end of the reversing tube, a hole is opened at the bottom end of the bidirectional tube holder, and the driving rod is passed through the hole.

The driving cylinder is sleeved on the end of the driving rod close to the reversing motor. The output shaft of the reversing motor can drive the driving sleeve to rotate, thereby realizing the conversion of the diversion direction of the reversing tube.

[0010] As a further solution of the present invention, the pressure reversing device includes a shell rod, which is fixedly installed on the upper end of the movable tube. A filling piece is sleeved on the end of the shell rod away from the movable tube. The upper end of the filling piece is in contact with the bottom end of the cushion. An extension shaft is fixedly installed on the bottom end of the filling piece, and the extension shaft is located inside the shell rod.

[0011] As a further solution of the present invention, a plurality of arc-shaped conducting blocks are fixedly installed on the inner bottom end of the movable tube, and the mutually close ends of the plurality of arc-shaped conducting blocks are rotatably connected to a spherical shell, and the extension shaft and the spherical shell are fixedly connected by a transmission rope.

[0012] As a further solution of the present invention, a connecting piece is fixedly installed on the inner bottom end of the movable tube, the arc-shaped conducting block is located above the connecting piece, a bellows is fixedly installed on the upper end of the connecting piece, the end of the bellows away from the connecting piece is fixedly connected to the spherical shell, and a pin tube is fixedly installed on the inner bottom end of the bellows.

[0014] As a further solution of the present invention, a sleeve is fixedly installed on the upper end of the support plate, and the sleeve is slidably sleeved on the bottom end of the pin tube.

[0015] As a further solution of the present invention, a fixing frame is fixedly installed on the right end of the support plate, a lifting electric push rod is fixedly installed on the bottom end of the fixing frame, a piston is slidably installed on the inner end of the infusion cylinder, and the telescopic end of the lifting electric push rod is fixedly connected to the piston. The telescopic end of the electric push rod then drives the piston to move, thereby promoting the flow of hydraulic oil.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During use, the present invention uses hydraulic oil to push the club upward, thereby slowly lifting the patient's limbs. The surrounding soft pads protruding from the club will support the patient, helping to stabilize the patient's limbs and reduce unnecessary movement, thereby ensuring that radiation can accurately target and irradiate the tumor site, improving the accuracy and effectiveness of treatment, and helping patients maintain a comfortable posture, reducing the discomfort and fatigue that may be caused by maintaining a certain posture for a long time, making it easier for patients to cooperate with treatment;

[0018] 2. During use, the present invention can more accurately locate the tumor by slightly elevating the patient's limb, so that the radiation is more concentrated in the tumor area, thereby reducing radiation damage to surrounding healthy tissues, thereby avoiding or reducing radiation damage to vital organs, protecting the patient's normal physiological functions. For some tumors with complex or difficult-to-reach locations, by adjusting the position of the pathogen's limb, better irradiation can be achieved, solving problems that are difficult to handle with conventional methods; BRIEF DESCRIPTION OF THE DRAWINGS

The bottom end of the reversing tube 205 is connected to the inner bottom end of the two-way trustee 201 by a reset spring 206.

[0042] like Figure 5 、 7 As shown, more specifically, among the four bidirectional tubes 201 fixedly connected to the support link 305, every two bidirectional tubes 201 are connected to each other, and the bottom end of the connection of the bidirectional tubes 201 that are connected to each other is fixedly connected to a return pipe 503. A total recovery pipe is provided in the support plate 101, and the output end of the return pipe 503 is fixedly connected to the liquid storage tank 3 through the total recovery pipe ( Figure 5 (A schematic diagram of a single group of connection relationships is shown in the figure), the main recovery pipe is used to merge and integrate the return pipes 503 distributed in the rectangular array within the enclosure 102. Only one main recovery pipe is required to realize the recovery of the hydraulic oil. The reversing tube 205 is hollow inside and has a hole opened horizontally on the outer surface. The hole is "L" shaped. When the patient lies on the cushion 6, the support block 202 squeezes the ball rod 204 downward, and the downward movement of the ball rod 204 pushes the reversing tube 205 downward, thereby realizing that the bottom of the "L" hole of the reversing tube 205 is aligned with the output end of the two-way hosting tube 201.

[0043] like Figure 7, a driving rod 207 is fixedly installed on the bottom end of the reversing tube 205, a hole is opened at the bottom end of the two-way hosting tube 201, and the driving rod 207 is passed through the hole, and a reversing motor 502 is fixedly installed on the bottom end of the support plate 103, and a driving cylinder 501 is fixedly installed on the output end of the reversing motor 502, and the driving cylinder 501 is sleeved on the end of the driving rod 207 close to the reversing motor 502. Specifically, a rectangular block is fixedly installed on the end of the driving rod 207 close to the reversing motor 502, and a rectangular groove is fixedly opened at the inner end of the driving cylinder 501, and the rectangular block is arranged in the rectangular groove, so that the driving cylinder 501 rotates to drive the driving rod 207 to rotate without slipping.

[0044] See also Figure 8 、 9 The pressure reversing device includes a shell rod 304, which is fixedly welded to the upper end of the movable tube 301. Specifically, a sliding protrusion is fixedly installed on the outer surface of the movable tube 301 near the support link 305 to prevent the movable tube 301 from turning. A groove of the same size as the sliding protrusion is opened at the inner end of the support link 305 near the movable tube 301. The sliding protrusion is arranged in the groove, thereby effectively preventing the movable tube 301 from rotating.

[0045] The end of the shell rod 304 away from the movable tube 301 is provided with a filling piece 302, and the upper end of the filling piece 302 is in contact with the bottom end of the cushion 6. Specifically, the end of the filling piece 302 close to the cushion 6 is fixedly installed with a rubber pad to prevent the corners of the filling piece 302 from scratching the cushion 6 and thus affecting the service life. More specifically, the filling piece 302 is used to fill the gap between the four support blocks 202, and the upper end of the shell rod 304 is circular. The filling piece 302 and the end of the shell rod 304 away from the movable tube 301 are smeared with lubricating grease to improve the lubrication between them while extending the service life. The upper end of the shell rod 304 is a spherical structure so that the filling piece 302 can rotate in any direction.

[0046] See also Figure 9 、 10The bottom end of the filling piece 302 is fixedly installed with an extension shaft 306, and the extension shaft 306 is located inside the shell rod 304. A plurality of arc-shaped conducting blocks 309 are fixedly installed at the inner bottom end of the movable tube 301. The ends of the plurality of arc-shaped conducting blocks 309 close to each other are rotatably connected to the spherical shell 308. The spherical shell 308 is hollow, and a sealing gasket is fixedly installed on the outer surface of the spherical shell 308, thereby further ensuring the sealing between the arc-shaped conducting blocks 309. The extension shaft 306 and the spherical shell 308 are fixedly connected by a transmission rope 307. Specifically, there are four transmission ropes 307, the upper ends of which are fixedly connected to the four vertices of the extension shaft 306, and the lower ends are respectively on the outer surface of the spherical shell 308 corresponding to the four vertices of the extension shaft 306. After the filling piece 302 changes its angle, the bottom end pulls the spherical shell 308 through the extension shaft 306 and the transmission rope 307 to follow the filling piece 302 to rotate at the same angle.

[0047] See also Figure 10 、 11 A connecting piece 311 is fixedly installed at the inner bottom end of the movable tube 301, and the arc-shaped conducting block 309 is located above the connecting piece 311. A bellows 310 is fixedly installed at the upper end of the connecting piece 311. The end of the bellows 310 away from the connecting piece 311 is fixedly connected to the spherical shell 308. A pin tube 313 is fixedly installed at the inner bottom end of the bellows 310, and the upper end of the pin tube 313 is fixedly connected to the conducting pipe 312. The conducting pipe 312 is a high-pressure resistant hose, and the bellows 310 is sleeved on the outer surface of the conducting pipe 312. The end of the conducting pipe 312 away from the pin tube 313 is fixedly connected to the spherical shell 308.

[0048] Specifically, four holes are provided on the outer surface of the spherical shell 308, and the four holes correspond to the four arc-shaped conducting blocks 309 respectively. The arc-shaped conducting block 309 is provided with holes on a side close to the spherical shell 308. The holes are irregularly conical. The higher the inner cavity of the hole is, the larger the chamber is, and vice versa. To maximize the flow of liquid, the holes must be offset upward to maximize the flow of liquid. The corresponding holes will be towards the smallest point of the irregular conical hole, and the flow of liquid will be blocked, thereby slowing down the flow of liquid.

[0049] More specifically, the output end of the movable tube 301 is fixedly connected to the input end of the bidirectional tube 201 via a transmission tube 303 , which is a high-pressure resistant hose.

[0050] See also Figure 10 、 11, 12. A sleeve 314 is fixedly installed on the upper end of the support plate 101, and the sleeve 314 is slidably sleeved on the bottom end of the pin tube 313. A conducting groove is provided at the inner end of the sleeve 314, and the upper side of the conducting groove does not completely pass over the inner upper end of the sleeve 314. A through hole is provided on the outer surface of the pin tube 313 near the sleeve 314. When the movable tube 301 moves downward, the pin tube 313 moves downward, thereby realizing the connection between the through hole and the conducting groove, thereby realizing the circulation of liquid. The bellows 310 is used to protect the conducting tube 312 from physical scratches. At the same time, the bellows 310 can absorb and isolate the vibration generated by the mechanical equipment.

[0051] A fixing frame 105 is fixedly installed on the right end of the support plate 101, and a lifting electric push rod 4 is fixedly installed on the bottom end of the fixing frame 105. A piston 110 is slidably installed on the inner end of the infusion cylinder 104. The telescopic end of the lifting electric push rod 4 is fixedly connected to the piston 110 by bolts. The end of the infusion cylinder 104 away from the lifting electric push rod 4 is fixedly connected to the output tube 315, and the output tube 315 is fixedly connected to the sleeve 314 through the main pipe (not shown in the figure).

[0052] The working principle of the present invention is:

[0053] During use, the patient first lies on the cushion 6, and under the action of the patient's own weight, the support block 202 and the filling piece 302 in the area where the patient lies are pressed downwards. When the support block 202 moves downwards, the ball rod 204 is pressed downwards, and at the same time, the movable cylinder 203 also moves downwards along with the ball rod 204. At this time, under the action of the limit ring, the reversing tube 205 also moves downwards, and the pressure-sensitive device in the driving cylinder 501 is immediately triggered, and the reversing motor 502 is energized. The driving cylinder 501 drives the driving rod 207 to rotate, and the driving rod 207 drives the reversing tube 205 to rotate, so that the "L" of the reversing tube 205 is directed to the input end of the bidirectional tube 201, while the pressure-sensitive devices in other areas do not receive pressure, so that the reversing motor 502 is in a standby state.

[0054] In order to achieve more accurate positioning of the tumor in the patient's body, at this time, the output shaft of the steering motor 109 drives the driving gear 108 to rotate, and the arc-shaped rack 106, under the meshing action with the driving gear 108 and the thrust assistance of the tilting electric push rod 107, drives the support plate 101 to achieve angular deviation, so that the tumor can be more accurately positioned in the patient;

[0055] At the same time, the filling piece 302 also moves downward due to the gravity brought by the patient. At this time, as the filling piece 302 moves downward, the shell rod 304 and the movable tube 301 move downward. When the movable tube 301 moves downward, the pin tube 313 moves downward, thereby achieving communication between the through hole and the conducting groove, lifting the telescopic end of the electric push rod 4 to drive the piston 110 to move to the left, thereby pushing the hydraulic oil inside the infusion cylinder 104 into the sleeve 314 through the output pipe 315, and then the hydraulic oil is discharged from the sleeve 31 4 enters the guide tube 312 and finally enters the spherical shell 308. At the same time, the cushion 6 is concave in the shape of the human body contour. The pressure-sensitive device around the outer contour of the human body is also triggered. The support block 202 and the filling piece 302 in the contour area of ​​the human body are deflected due to the unbalanced force. When the filling piece 302 deflects, the bottom end of the filling piece 302 changes its angle, pulling the spherical shell 308 through the extension shaft 306 and the transmission rope 307 to rotate with the filling piece 302 at the same angle.

[0056] At this time, since the offset angle of the ball shell 308 is toward the outside of the human body contour line, the hydraulic oil preferentially enters the movable cylinder 203 around the patient through the transmission tube 303 and the reversing tube 205, and only a small amount of hydraulic oil enters the movable cylinder 203 pressed by the patient's weight, and then first pushes up the ball rod 204, causing the soft pad 6 around the patient to bulge. Then, after the ball rod 204 around the patient can no longer rise, the hydraulic oil will concentrate into the movable cylinder 203 pressed by the patient's weight, and push the ball rod 204 upward through the hydraulic oil, thereby slowly lifting the patient's limbs. The soft pad 6 around the patient that is pushed up by the ball rod 204 will play a supporting role, thereby preventing the patient's muscles from being stressed and twitching, resulting in the inability to accurately locate pathogens during treatment. By slightly lifting the organ, the tumor can be located more accurately, and the radiation can be more concentrated on the tumor area, thereby reducing radiation damage to surrounding healthy tissues.

[0057] After waiting for the treatment to be completed, the output shaft of the steering motor 109 drives the driving cylinder 501 to rotate so that the "L" of the reversing tube 205 points to the output end of the two-way tube 201, and then the oil pump inside the liquid storage tank 3 draws the hydraulic oil in the movable cylinder 203 into the liquid storage tank 3. After the telescopic end of the electric push rod 4 is lifted to drive the piston 110 to return to its initial state, as the oil pump gradually recovers the residual hydraulic oil in the movable cylinder 203, the hydraulic oil enters the infusion cylinder 104 again through the connecting pipe 111.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
