Description

Technical Field

[0001] The present invention relates to the technical field of radiotherapy, and particularly relates to a tumor radiotherapy instrument. Background Art

[0002] A tumor radiotherapy instrument is a medical device used to treat tumors including those in the gynecology, nasopharynx, esophagus, bronchus, rectum, bladder, breast, pancreas, etc. It irradiates the tumors in the patient's body by generating radiation such as X-rays or γ-rays, destroys the DNA of tumor cells, makes them lose the ability to reproduce or directly causes cell death, and is widely used in medical institutions such as hospitals, tumor treatment centers, and outpatient surgery centers.

[0003] The patent specification with the publication number CN208049209U discloses a tumor radiotherapy instrument, which includes a treatment component and an auxiliary component. The treatment component includes a treatment chamber, an X-ray generator, and a base. The treatment chamber is fixedly connected to the base, the treatment chamber is located above the base, the X-ray generator is located on the inner surface of the treatment chamber, and the X-ray generator is electrically connected to an external power supply; When this treatment instrument is in use, by having the patient hold the armrest, winding the elastic band around the patient's wrist, and then snapping the fixed buckle at the fixed ear, the patient's hand is thus kept on both sides of the head; however, the disadvantage of this technical solution is that the armrest is fixedly connected to the end of the treatment bed. Due to differences in shoulder width among users of different body types, there are differences in the relatively comfortable holding positions of the two hands over the head. Also, when the armrest is in use, the patient needs to maintain an active holding posture for a long time, and radiotherapy usually takes more than 10 minutes. That is, maintaining the treatment posture in an active holding posture that does not match the body type for a long time makes it easy for the patient to have a problem of holding fatigue at the hand position. Summary of the Invention

[0004] The purpose of the present invention is to provide a tumor radiotherapy instrument, and the technical problems to be solved are as follows: The existing device for assisting patients in maintaining the tumor radiotherapy posture is prone to cause the problem of holding fatigue at the patient's hand position during use.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A tumor radiotherapy instrument includes a treatment chamber. A secondary slideway is arranged inside the treatment chamber. A support platform is arranged on one side of the treatment chamber. A bed body is slidably connected to the top of the support platform. A handrest mechanism is detachably installed on one side of the top of the bed body. The handrest mechanism includes a support component and a handrest component. The support height of the support component is adapted to the weight of the patient's hand. The handrest component is used for placing the hand and can maintain the free rotation of the hand.

[0006] As a further solution of the present invention: a console and a display instrument are arranged on one side of the treatment cabin, the console is electrically connected to the support platform, a displacement motor for driving the bed body is installed inside the support platform, a main slideway is arranged at the top of the support platform, the main slideway is slidably connected to the bed body, and the main slideway is adaptively butted with the secondary slideway.

[0007] As a further solution of the present invention: the support assembly includes a bottom plate, the bottom plate is installed on one side of the top of the bed body close to the secondary slideway, three straight plates are fixedly connected to the top of the bottom plate, a top plate is fixedly connected between the tops of the straight plates, a vertical moving groove is arranged between two adjacent straight plates, a lifting member is installed between the vertical moving groove and the top plate, and the handle assembly is installed between the tops of the two lifting members.

[0008] As a further solution of the present invention: the lifting member includes a sleeve fixedly connected to the top of the top plate, a rod sleeve is slidably connected inside the sleeve, a limiting block is installed at the bottom of the rod sleeve in the sleeve, and a spring is installed between the outer side of the top of the rod sleeve and the top of the sleeve.

[0009] As a further solution of the present invention: an adhesive groove is arranged on the bottom surface of the bottom plate, and a colloid is attached inside the adhesive groove.

[0010] As a further solution of the present invention: the handle assembly includes a hand support seat fixedly connected between the tops of the two rod sleeves, a rotating member is installed on the top of the hand support seat, and a glove is installed inside the rotating member.

[0011] As a further solution of the present invention: the rotating member includes an outer rotating circle fixedly connected to the hand support seat, an inner ball groove is arranged inside the outer rotating circle, a plurality of balls are uniformly arranged inside the inner ball groove, an inner rotating circle is installed between the inner sides of the balls, and an outer ball groove adapted to the balls is arranged on the outer side of the inner rotating circle.

[0012] As a further solution of the present invention: a cortex is arranged between the inner rotating circle and the glove.

[0013] The beneficial effects of the present invention: In the present invention, by installing two support components on one side of the bed body and arranging a handrest component on the support components, during use, by installing the two support components of the handrest mechanism at the bed body near the treatment cabin, after the patient lies flat, the patient can place the hand on the handrest component above the two support components. The spring inside the support component is compressed by force and reaches a force balance with the weight of the hand placed thereon. That is, when the weight of the patient's hand is heavier, the hand sinks and is closer to the bed body; when the weight of the patient's hand is lighter, the sinking amplitude of the hand is smaller and it is farther from the bed. This avoids the problem that the arms of different patients are limited to the same height for continuous gripping actions when maintaining the treatment posture, thereby causing gripping fatigue. Moreover, with the support of the support component, the patient can maintain the natural hanging state of the hand in the form of passive support, improving the comfort of hand placement; Furthermore, by setting an adhesive groove at the bottom of the support component and fitting a replaceable colloid inside the adhesive groove, medical staff can determine the installation position of the support component according to the actual suitable treatment lying position of the patient. At the same time, due to the difference in shoulder width between the two hands of patients with different body types, the distance between the hands lifted to both sides of the head after lying flat is different. Then, with the help of the replaceable colloid, the treatment instrument can determine the installation position of the support component on the bed body according to the actual lying position and the suitable placement position of the hand. Its technical advantage is that the treatment instrument can use a more reasonable lying position to improve the more convenient radiotherapy for the patient's diseased position, and the support component that is more suitable for the distance between the two hands placed enables the patient to maintain the natural placement position of the hand during long-term radiotherapy, further improving the comfort of hand placement. In addition, the handrest component installed on the top of the support component is provided with a rotatable member that can be rotated arbitrarily on the outer side of the glove where the hand is placed. With the cortex between the rotatable member and the glove, the patient's hand can rotate freely and move in multiple directions to a certain extent while being supported. Its purpose is to provide a certain degree of free movement ability for the patient's wrist while maintaining the treatment posture, avoiding the situation of unidirectional gripping of the handrail in the prior art, and further improving the comfort of the patient's hand during radiotherapy.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] As Figures 1 to 4 shown, a tumor radiotherapy instrument includes a treatment cabin 1. A secondary slideway 2 is arranged inside the treatment cabin 1. A support platform 3 is arranged on one side of the treatment cabin 1. The top end of the support platform 3 is slidably connected with a bed body 4. A handrest mechanism 5 is detachably installed on one side of the top end of the bed body 4. The handrest mechanism 5 includes a support component 51 and a handrest component 52. The support height of the support component 51 is adapted to the weight of the patient's hand. The handrest component 52 is used for placing the hand and can maintain the free rotation of the hand. It should be noted that a control console 6 and a display instrument 7 are arranged on one side of the treatment cabin 1. The control console 6 is electrically connected with the support platform 3. A displacement motor for driving the bed body 4 is installed inside the support platform 3. The display instrument 7 is used to feedback the control information on the control console 6. A main slideway 8 is arranged at the top end of the support platform 3. The main slideway 8 is slidably connected with the bed body 4. The main slideway 8 is adapted and docked with the secondary slideway 2. When the radiotherapy instrument is in use, medical staff input an instruction to displace the bed body 4 on the control console 6, then the displacement motor inside the support platform 3 drives the bed body 4 to reciprocate between the main slideway 8 and the secondary slideway 2. When the bed body 4 enters the secondary slideway 2 inside the treatment cabin 1, it does not disengage from the main slideway 8, so the reciprocating motion can be realized, which is convenient for the radiotherapy instrument to move the patient conveniently.

[0019] As Figure 2As shown in the figure, the support component 51 includes a bottom plate 511. The bottom plate 511 is installed on one side of the top end of the bed body 4 close to the secondary slideway 2. Three straight plates 512 are fixed to the top end of the bottom plate 511. A top plate 513 is fixedly connected between the top ends of the respective straight plates 512. Vertical movement grooves 514 are provided between two adjacent straight plates 512. A lifting member 515 is installed between the vertical movement grooves 514 and the top plate 513. The handrest component 52 is installed between the top ends of the two lifting members 515; The lifting member 515 includes a sleeve 5151 fixedly connected to the top end of the top plate 513. A sleeve rod 5152 is slidably connected inside the sleeve 5151. A limit block 5153 is installed at the bottom of the sleeve rod 5152 in the sleeve 5151. The limit block 5153 is used to prevent the sleeve rod 5152 from detaching from the sleeve 5151. A spring 5154 is installed between the outer side of the top of the sleeve rod 5152 and the top end of the sleeve 5151. The elastic coefficient of the spring 5154 is 5 - 10 N / mm, and the applicable weight range of the patient's hand is 2 - 8 kg. The spring 5154 is made of silicon manganese alloy material, with a wire diameter of 1.2 mm and 8 effective turns; It should be noted that when the patient places the hand on the handrest component 52 at the top end of the support component 51, the weight of the patient's hand will press on the sleeve rod 5152 of the lifting member 515. The sleeve rod 5152 moves downward along the sleeve 5151 towards the vertical movement groove 514 under the force. There is a gap between the vertical movement groove 514 and the top end of the bottom plate 511 to ensure the downward movement space. During the downward movement, the spring 5154 is compressed by the force until the weight of the patient's hand and the elastic force of the spring 5154 reach equilibrium. Thus, the support component 51 achieves adaptive support for the patient's hand. In addition, the lifting member 515 includes, but is not limited to, a rebound structure, and can also be realized by matching a weight sensor with a micro cylinder, that is, measuring the weight of the hand through the weight sensor, and the micro cylinder performs vertical expansion and contraction according to the weight.

[0020] As Figure 3 shown, an adhesive groove 516 is provided on the bottom surface of the bottom plate 511, and a colloid 517 is fitted inside the adhesive groove 516; It should be noted that due to the differences in the height of the patient and the shoulder width between the two hands, during radiotherapy, to ensure that the treatment bed body 4 is sent into the treatment chamber 1 and the position where the patient needs radiotherapy can be effectively covered, the lying position of the patient needs to be adjusted. Moreover, there are differences in the appropriate placement positions of the two hands raised above the head after lying down. To adapt to this difference, an adhesive groove 516 is provided on the bottom surface of the bottom plate 511 of the support component 51. After the medical staff determine the appropriate lying position of the patient and the appropriate placement position of the hands, they then fit a strong colloid 517 into the adhesive groove 516 to fix the support component 51 at the appropriate position on the bed body 4.

[0021] As Figure 2 and Figure 4As shown, the handrest component 52 includes a handrest seat 521 fixedly connected between the tops of two sleeve rods 51 and 52. A rotating member 522 is installed at the top of the handrest seat 521, and a glove 523 is installed inside the rotating member 522; The rotating member 522 includes an outer rotating ring 5221 fixedly connected to the handrest seat 521. An inner ball groove 5222 is provided inside the outer rotating ring 5221. A large number of balls 5223 are evenly arranged inside the inner ball groove 5222. The balls 5223 are made of medical ceramics and support the hand to freely rotate within the range of ±30°. The number of the balls 5223 is 36, arranged equidistantly along the circumference, with a diameter of 3 mm. An inner rotating ring 5224 is installed inside each ball 5223. An outer ball groove 5225 adapted to the balls 5223 is provided on the outer side of the inner rotating ring 5224; It should be noted that when the patient raises the hand above the head and inserts the hand into the glove 523, compared with holding the handrail in the prior art, on the one hand, there is no need to actively hold, and on the other hand, it will not be limited in one direction. It can be supported by the support component 51 and can move freely by rotating the wrist. When rotating the wrist, the glove 523 drives the inner rotating ring 5224 to rotate, and the balls 5223 on the outer side of the inner rotating ring 5224 provide support for the rotation process. Then, through the use of the handrest mechanism 5, the patient can maintain the comfort of the hand while maintaining the treatment posture; in addition, a cortex 524 is provided between the inner rotating ring 5224 and the glove 523. Then, when the patient rotates the wrist, the wrist can be further moderately moved in all directions, further improving the comfort during treatment.

[0022] The above has described a specific embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
