Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy, and specifically provides a protective device for radiotherapy. Background Art

[0002] When patients with advanced cervical cancer receive radiotherapy, if the ovaries are exposed to radiation during the radiotherapy process, it is easy to cause loss of ovarian function. The traditional approach is to move the ovaries to a certain position, move the ovaries out of the radiation area, and avoid the ovaries being exposed to radiation.

[0003] However, for patients with lymph node metastasis, the range of radiotherapy is very large, and the ovaries cannot be moved out of the radiation area, which also leads to radiation exposure to the ovaries during radiotherapy, resulting in loss of ovarian function. At the same time, radiotherapy requires several months of treatment, so during the long radiotherapy period, the ovaries that have been moved out of the radiotherapy area may also move back to the radiotherapy area, causing the ovaries to be exposed to radiation. Therefore, there is a problem in the prior art that radiation irradiates the ovaries during radiotherapy, resulting in loss of ovarian function. Utility Model Content

[0004] The utility model provides a protective device for radiotherapy, which is used to solve the problem of ovarian function loss caused by ovarian radiation during radiotherapy.

[0005] The technical solution of the utility model is as follows:

[0006] A protective device for radiotherapy comprises a protective bag, wherein the protective bag is provided with a lead-plastic layer for blocking radiation, and a tightening structure is provided at the bag opening of the protective bag for tightening the bag opening of the protective bag.

[0007] In this solution, a lead plastic layer can be used to block radiation and prevent radiation from damaging the ovaries protected by the protective bag. A tightening structure can be used to tighten the mouth of the protective bag, and the protective bag is used to block radiation and prevent radiation from irradiating the ovaries during radiotherapy. When in use, the protective bag is placed on the ovaries, and the tightening structure is used to tighten the mouth of the protective bag. After the mouth of the protective bag is tightened, the ovaries can be prevented from detaching from the protective bag, thereby achieving the purpose of fixing the protective bag to the ovaries. Under the protective effect of the protective bag, the ovaries can be prevented from being directly exposed to radiation and damaged, thereby solving the problem of radiation damaging the ovaries during radiotherapy.

[0008] The tightening structure is made of elastic material, and tightens the pocket of the protective belt through elastic force.

[0009] In this solution, the tightening structure made of elastic material can tighten the bag opening of the protective bag through elastic force, so that the protective bag is bound to the ovary. The elastic force of the tightening structure can continuously provide force to tighten the bag opening, so that the bag opening is stably covered on the ovary. The tightening structure automatically tightens the bag opening under the action of the elastic force, which can solve the problem that the protective bag is difficult to fix.

[0010] It also includes an operating rod, the operating rod is provided with a first joint, the protective bag is provided with a second joint adapted to the first joint, and the operating rod is detachably connected to the protective bag through the first joint and the second joint.

[0011] In this solution, the protective bag can be moved to the position of the ovary by an operating rod, and then the mouth of the protective bag can be opened by tweezers or other tools, and then the protective bag can be put on the ovary. After the tightening structure tightens the mouth of the bag so that the protective bag is stably put on the ovary, the connection between the first joint and the second joint is disconnected to separate the operating rod from the protective bag. During radiotherapy, the protective bag is always put on the ovary. After the radiotherapy is completed, the operating rod is moved into the abdominal cavity to connect the first joint with the second joint. The protective bag can be moved by the operating rod, so as to be taken out of the abdominal cavity. The provision of the operating rod, the first joint and the second joint can solve the problem of inconvenient placement of the protective bag.

[0012] The first joint and the second joint are respectively provided with matching threaded holes and external threads.

[0013] A guide hole and a guide portion are provided between the first joint and the second joint.

[0014] In this solution, the guide hole and the guide portion are provided to guide the first joint and the second joint to align, thereby reducing the difficulty of connecting the first joint and the second joint and improving the connection efficiency of the first joint and the second joint.

[0015] The guide hole is a conical hole, and the guide portion is a conical structure.

[0016] In this solution, the conical hole can guide the conical structure to slide, so that the first joint and the second joint can be quickly connected.

[0017] It also includes a locking pipe fitting, which is sleeved on the operating rod. The second joint is provided with a locking structure. The locking pipe fitting is provided with a locking portion adapted to the locking structure. The locking pipe fitting is used to constrain the second joint and prevent the second joint from rotating circumferentially relative to the locking pipe fitting.

[0018] In this solution, the locking tube can constrain the second joint and prevent the second joint from rotating, ensuring that the first joint can be stably separated or connected to the second joint. After the locking tube is connected to the second joint, it is only necessary to hold the locking tube and keep the locking tube from rotating to prevent the second joint from rotating and avoid the protective bag from being separated from the ovary.

[0019] The tightening structure is an elastic clip, and the elastic clip is connected to the bag opening of the protective bag.

[0020] In this embodiment, the elastic clip has an opening so that it can be clamped on the ovary. Compared with structures such as rubber bands, the elastic clip will not be blocked by tissues such as the fallopian tube that connects the ovary to the human body.

[0021] The bag opening of the protective bag is provided with an expansion notch, and the position of the expansion notch corresponds to the opening position of the elastic clip.

[0022] In this solution, when the opening of the elastic clip expands, the expansion notch will follow the deformation, ensuring that the opening of the protective bag can adapt to the deformation of the elastic clip. In addition, the expansion notch can make the opening of the protective bag larger.

[0023] The radiotherapy protection device also includes a sleeve, which is sleeved on the operating rod and is used to accommodate the elastic clip.

[0024] In this solution, a sleeve is provided to accommodate the elastic clip. When the elastic clip and the protective bag need to be put into or taken out of the body, the elastic clip can be first stored in the sleeve by the operating rod, and the elastic clip can be taken out by taking out the sleeve.

[0025] Beneficial effects of the utility model:

[0026] The utility model protects the ovary by providing a protective bag with a lead plastic layer. When the protective bag is placed on the ovary, the radiation cannot cause damage to the ovary. The tightening structure provided on the protective bag can fix the protective bag to the ovary, so that the protective bag is stably and continuously connected to the ovary to protect the ovary.

[0040] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0041] Embodiment 1,

[0042] like Figure 1 As shown, the first embodiment provides a radiotherapy protection device, including a protection bag 1, a tightening structure and an operating rod 6. The tightening structure is arranged at the bag opening of the protection bag 1 and is used to tighten the bag opening of the protection bag 1. One end of the operating rod 6 is detachably connected to the protection bag 1. The operating rod 6 is used to move the protection bag 1 to the position of the ovary that needs to be protected, and then fix the protection bag 1 to the ovary through the tightening structure. The operating rod 6 is provided with a first joint 5, and the protection bag 1 is provided with a second joint 3 adapted to the first joint 5. The operating rod 6 is detachably connected to the protection bag 1 through the first joint 5 and the second joint 3.

[0043] The first joint 5 and the second joint 3 may be connected by threaded connection. For example, the first joint 5 is provided with a threaded hole, and the second joint 3 is provided with an external thread matched with the threaded hole. Alternatively, the second joint 3 is provided with a threaded hole, and the first joint 5 is provided with an external thread matched with the threaded hole.

[0044] like Figure 2 As shown, the first joint 5 and the second joint 3 are respectively provided with a guide hole and a guide portion, and the guide hole and the guide portion are used to guide the first joint 5 and the second joint 3 to dock, so that the external thread enters the threaded hole, reducing the difficulty of connecting the external thread and the threaded hole.

[0045] The guide hole may be a tapered hole 7, and the guide portion may be a conical structure 4. The conical structure 4 may slide along the tapered hole 7, so that the first joint 5 is aligned with the second joint 3, and the external thread is coaxial with the threaded hole.

[0046] like Figure 3 and Figure 4 As shown, the guide hole can also be a special-shaped hole composed of a round hole and a slide groove 8, and the shape of the guide structure is a triangle. The slide groove 8 is connected to the round hole, and the bottom of the slide groove 8 is used to guide the guide structure to slide into the round hole, so that the first joint 5 is aligned with the second joint 3, and the external thread is coaxial with the threaded hole.

[0047] The first joint 5 and the operating rod 6 can be connected by welding, or the first joint 5 and the operating rod 6 can be integrally formed.

[0048] The protective bag 1 comprises a lead-plastic layer and a plastic layer. Plastic layers are respectively arranged on both sides of the lead-plastic layer. The lead-plastic layer is used to isolate radiotherapy rays, and the plastic layer is used to isolate the lead-plastic layer to prevent the lead-plastic layer from contacting human tissue.

[0049] The tightening structure may be a rubber band 2 , which is connected to the bag opening of the protection bag 1 . The elastic force of the rubber band 2 can be used to tighten the bag opening of the protection bag 1 .

[0050] The tightening structure and the protective bag 1 can be connected by bonding or hot melting.

[0051] Embodiment 2

[0052] The second embodiment provides a protective device for radiotherapy. The difference from the first embodiment is that the tightening structure of the second embodiment is different.

[0053] like Figure 5As shown, the tightening structure can also be an elastic clip 9, which is a semicircular ring structure with an opening. The size of the opening can be opened or reduced, and the semicircular ring structure can be made of elastic plastic or metal, and the elastic clip 9 is connected to the bag opening.

[0054] like Figure 6 As shown, the bag opening is provided with an expansion notch 10, and the position of the expansion notch 10 corresponds to the position of the opening. When the opening of the elastic clip 9 expands, the width of the expansion notch 10 increases. The expansion notch 10 is provided on a side away from the second joint 3.

[0055] like Figure 7 and Figure 8 As shown, the second joint 3 is provided with two connecting legs 13, and the two connecting legs 13 are respectively hinged with the elastic clip 9, and the threaded hole is opened in the second joint 3, and the threaded hole is located between the two connecting legs 13. The threaded hole passes through the second joint 3, and the external thread provided on the first joint 5 is connected with the threaded hole. The axial length of the external thread of the first joint 5 is greater than the axial length of the threaded hole, and the external thread part of the first joint 5 abuts against the elastic clip 9 after passing through the threaded hole. Twisting the first joint 5 can make the first joint 5 continue to move toward the elastic clip 9, thereby compressing the elastic clip 9, and the two ends of the elastic clip 9 swing outward around the hinge point respectively, so that the opening of the elastic clip 9 opens. If the first joint 5 is twisted in the opposite direction, the pressure on the open ring of the elastic block can be gradually reduced, and the elastic clip 9 recovers its deformation under the action of its own elastic force, that is, the elastic clip 9 gradually shrinks until the external thread part of the first joint 5 leaves the elastic clip 9.

[0056] It should be noted that the first joint 5 is provided with a guide portion, so when it contacts the elastic clip 9 , the guide portion at the end of the external thread contacts the elastic clip 9 .

[0057] The second joint 3 is provided with a locking structure, and the operating rod 6 is provided with a locking pipe 11. The locking pipe 11 is sleeved on the operating rod 6, and the locking pipe 11 is provided with a locking portion that cooperates with the locking structure. The locking pipe 11 can rotate and slide relative to the operating rod 6. When the locking portion cooperates with the locking structure, the second joint 3 and the locking pipe 11 are relatively fixed, and the second joint 3 and the locking pipe 11 cannot rotate relative to each other, and the operating rod 6 can still rotate relative to the locking pipe 11. The locking pipe 11 and the locking structure are provided to prevent the second joint 3 from rotating when the first joint 5 rotates, and to prevent the elastic clip 9 from moving when the first joint 5 rotates, thereby ensuring that the position of the protective bag 1 remains unchanged.

[0058] like Fig.10As shown, the locking structure can be a positioning hole 16, and the locking part is a positioning pin 17. The positioning pin 17 is arranged at the end of the locking pipe 11. When the positioning pin 17 is inserted into the positioning hole 16, the locking structure is connected to the second joint 3. At this time, holding the locking pipe 11 can prevent the second joint 3 from rotating.

[0059] like Fig. 9 As shown, the locking structure can also be a hexagonal column structure 14, and the threaded hole is opened on the end face of the hexagonal column structure 14, and the threaded hole is coaxial with the hexagonal column structure 14. The locking portion is a hexagonal hole 15 adapted to the hexagonal column structure 14, and the cooperation between the hexagonal hole 15 and the hexagonal column can refer to the cooperation between a wrench and a nut. When the hexagonal hole 15 is sleeved on the hexagonal column structure 14, the hexagonal column structure 14 cannot rotate, and the elastic clip 9 and the protective bag 1 will not rotate under the action of the first joint 5.

[0060] It also includes a sleeve 12, the inner diameter of which is greater than the outer diameter of the locking tube 11, and the sleeve 12 is sleeved on the locking tube 11. The sleeve 12 is used to accommodate the protective bag 1 and the elastic clip 9. When the first joint 5 is connected to the second joint 3, the elastic clip 9 can be pulled by the operating rod 6 to move the elastic clip 9 into the sleeve 12. When the elastic clip 9 moves toward the sleeve 12, the elastic clip 9 contacts the tube wall of the sleeve 12. Because the operating rod 6 applies a force to move the elastic clip 9, the elastic clip 9 is subjected to a reaction force from the tube wall. After being subjected to the reaction force from the tube wall, the elastic clip 9 is deformed by the force and gradually moves into the sleeve 12. The sleeve 12 can reduce the width of the elastic clip 9, thereby facilitating the removal of the elastic clip 9 from the body.

[0061] The length of the locking pipe 11 is greater than the length of the sleeve 12 , so that the locking pipe 11 can be easily operated from the other end of the sleeve 12 .
