Description

Technical Field

[0001] This utility model relates to the field of medical positioning films, specifically reusable medical positioning films. Background Technology

[0002] Medical positioning films are a crucial auxiliary tool in the modern medical field. They are usually made of special low-temperature thermoplastic sheets, which have good flexibility, fit and memory properties. They can be repeatedly shaped and used. In radiotherapy, they can accurately locate the tumor site, guide the direction of the radiation, minimize damage to surrounding healthy tissues, and ensure the treatment effect.

[0003] Chinese patent CN213077251U discloses a radiotherapy compensator positioning membrane, comprising a first positioning membrane placement plate, a second positioning membrane placement plate, a third positioning membrane placement plate, a fixing device, and a positioning membrane body. The first and second positioning membrane placement plates are integrally formed. The second positioning membrane placement plate is positioned at the top of the first positioning membrane placement plate. Two sets of mounting frames are symmetrically welded to the front surface of the first positioning membrane placement plate. Multiple sets of threaded holes are equidistantly opened on the front end faces of both sets of mounting frames. Each set of threaded holes is threaded with a fixing bolt. The front end face of the first positioning membrane placement plate is covered by the positioning membrane body. The two sides of the positioning membrane body extend into two cavities formed by the two sets of mounting frames and the first positioning membrane placement plate. Two sets of fixing devices are connected to the two vertical outer walls of the first positioning membrane placement plate. The bottom end of the first positioning membrane placement plate is connected to the third positioning membrane placement plate via two sets of lead screws and one set of bolts.

[0004] In actual use, when fixing the positioning film using the fixing device, multiple fixing bolts need to be tightened one by one to ensure that the positioning film is locked. The operation is slow, time-consuming and inefficient. Moreover, the tightening force cannot be well controlled during the tightening process, which may damage the positioning film. Therefore, it is necessary to modify the existing technology. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a reusable medical positioning film to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reusable medical positioning film, comprising a placement plate, a limiting groove formed on the outer wall of the placement plate, a sliding plate slidably mounted on the outer wall of the placement plate, a limiting block mounted on the outer wall of the sliding plate, a first spring mounted on the outer wall of the sliding plate, and a fixing block mounted at the end of the limiting block; a positioning block slidably mounted on the inner wall of the limiting groove, a movable groove formed on the outer wall of the positioning block, and a rotating fixing block rotatably mounted on the outer wall of the positioning block; a positioning rod rotatably mounted on the inner wall of the limiting groove, and a second spring mounted on the inner wall of the limiting groove.

[0007] By adopting the above technical solution, the traditional method of fixing and removing the positioning film by tightening multiple fixing bolts one by one is replaced, which simplifies the fixing and removing process of the positioning film, saves work steps and labor costs, and improves work efficiency and ease of operation.

[0008] Furthermore, the outer wall of the placement plate is symmetrically provided with multiple sets of limiting grooves, and two sets of sliding plates are symmetrically installed on the outer wall of the placement plate.

[0009] By adopting the above technical solution, the convenience and efficiency of operation are improved. The two sets of sliding plates and multiple sets of limiting grooves work together to enhance the stability of the entire fixation device and effectively prevent the positioning membrane from shifting or loosening due to slight patient movements, changes in body position, or external impacts during use.

[0010] Furthermore, multiple sets of limiting blocks are installed at equal intervals on the outer wall of the sliding plate, and the limiting blocks correspond to the limiting grooves.

[0011] By adopting the above technical solution, the reliability of fixation is enhanced, the positioning membrane is firmly locked, and it is prevented from shifting or falling off. The limiting block and the limiting groove correspond to each other, so that medical staff can directly push the sliding plate without complicated debugging or repeated confirmation, so as to achieve efficient fixation of the positioning membrane and save operation time.

[0012] Furthermore, a first spring is sleeved on the outer wall of the limiting block, and the first spring connects the outer wall of the sliding plate and the outer wall of the placement plate.

[0013] By adopting the above technical solution, the first spring provides the power for the sliding plate to reset, driving the limit block to smoothly and quickly exit from the limit groove, thereby realizing the automatic unlocking of the positioning film.

[0014] Furthermore, two sets of rotating fixing blocks are symmetrically installed on the outer wall of the positioning block, and the shape of the rotating fixing blocks corresponds to that of the fixing blocks.

[0015] By adopting the above technical solution, the two sets of rotating fixing blocks cooperate with each other to build a stable locking system, which enhances the rigidity of the fixing structure and effectively prevents the positioning membrane from loosening or shifting under complex external forces, such as sudden violent limb movements of the patient or bumps during transportation.

[0016] Furthermore, the positioning rod is L-shaped, and the end of the positioning rod is located on the inner wall of the movable groove.

[0017] By adopting the above technical solution, the positioning rod and the movable groove cooperate with each other, which is conducive to multi-directional coordinated positioning, making the position of the positioning block more stable in the positioning groove.

[0018] Furthermore, when the second spring is not compressed, the rotating fixing block moves away from the limiting groove, and when the second spring is compressed, the rotating fixing block is pressed tightly against the inner wall of the limiting groove.

[0019] By adopting the above technical solution, when the second spring is not compressed, the rotating fixing block provides sufficient space for the initial placement and adjustment of the positioning film. When the second spring is compressed, the rotating fixing block clamps the fixing block, thus completing the fixation of the sliding plate.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention replaces the traditional method of fixing the positioning film by tightening multiple fixing bolts one by one by setting a limiting groove, a sliding plate, a limiting block, a first spring, a fixing block, a positioning block, a movable groove, a rotating fixing block, a second spring, and a positioning rod. This allows the positioning film to be fixed to the positioning film placement plate simply by pressing the sliding plate, and the limiting between the positioning film and the positioning film placement plate to be released by pressing the sliding plate again. This simplifies the fixing and releasing process of the positioning film, saves work steps and labor costs, improves work efficiency and ease of operation, and the cooperation between the various components ensures the stability and accuracy of fixing the positioning film, reducing the possibility of damage or misalignment of the positioning film due to improper operation.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Reusable medical positioning films, such as Figure 1 - Figure 6As shown, the device includes a placement plate 1, with a limiting groove 11 on its outer wall. A sliding plate 2 is slidably mounted on the outer wall of the placement plate 1, and a limiting block 21 is mounted on the outer wall of the sliding plate 2. The limiting block 21 corresponds to the limiting groove 11, which helps to enhance the reliability of the fixation, firmly lock the positioning membrane, and prevent it from shifting or falling off. The correspondence between the limiting block 21 and the limiting groove 11 allows medical staff to directly push the sliding plate 2 without complicated adjustments or repeated confirmations, achieving efficient fixation of the positioning membrane and saving operation time. A first spring 22 is mounted on the outer wall of the sliding plate 2, and a fixing block 23 is mounted at the end of the limiting block 21. A positioning block 3 is slidably mounted on the inner wall of the limiting groove 11, and a movable groove 31 is opened on the outer wall of the positioning block 3. A rotating fixing block 32 is rotatably mounted on the outer wall of the positioning block 3. Two sets of rotating fixing blocks 3 are symmetrically mounted on the outer wall of the positioning block 3. 2. The shape of the rotating fixing block 32 corresponds to that of the fixing block 23. The two sets of rotating fixing blocks 32 and fixing blocks 23 cooperate with each other to form a stable locking system, which enhances the rigidity of the fixing structure and effectively prevents the positioning membrane from loosening or shifting under complex external forces, such as sudden violent limb movements of the patient or bumps during transportation. The inner wall of the limiting groove 11 is rotatably installed with a positioning rod 34, and the inner wall of the limiting groove 11 is installed with a second spring 33. When the second spring 33 is not compressed, the rotating fixing block 32 is away from the limiting groove 11. When the second spring 33 is compressed, the rotating fixing block 32 is close to the inner wall of the limiting groove 11. When the second spring 33 is not compressed, the rotating fixing block 32 leaves sufficient space for the initial placement and adjustment of the positioning membrane. When the second spring 33 is compressed, the rotating fixing block 32 clamps the fixing block 23 to complete the fixation of the sliding plate 2.

[0032] Please see Figure 1 - Figure 5 The outer wall of the placement plate 1 is symmetrically provided with multiple sets of limiting grooves 11, and two sets of sliding plates 2 are symmetrically installed on the outer wall of the placement plate 1, which improves the convenience and efficiency of operation. The two sets of sliding plates 2 and the multiple sets of limiting grooves 11 cooperate with each other to enhance the stability of the entire fixation device and effectively prevent the positioning membrane from shifting or loosening due to slight movements, changes in body position or external impacts of the patient during use.

[0033] Please see Figure 1 - Figure 6 Multiple sets of limiting blocks 21 are installed at equal intervals on the outer wall of the sliding plate 2, and the limiting blocks 21 correspond to the limiting grooves 11, which helps to enhance the reliability of fixation, firmly lock the positioning film, and prevent it from shifting or falling off. The correspondence between the limiting blocks 21 and the limiting grooves 11 allows medical staff to directly push the sliding plate 2 without complicated debugging or repeated confirmation, so as to achieve efficient fixation of the positioning film and save operation time.

[0034] Please see Figure 1 - Figure 5The outer wall of the limiting block 21 is fitted with a first spring 22, and the first spring 22 connects the outer wall of the sliding plate 2 and the outer wall of the placement plate 1. The first spring 22 provides the power for the sliding plate 2 to reset, thereby driving the limiting block 21 to exit smoothly and quickly from the limiting groove 11, thus realizing the automatic unlocking of the positioning film.

[0035] Please see Figure 1 - Figure 6 Two sets of rotating fixing blocks 32 are symmetrically installed on the outer wall of the positioning block 3, and the shape of the rotating fixing blocks 32 corresponds to that of the fixing block 23. The two sets of rotating fixing blocks 32 and the fixing block 23 cooperate with each other to form a stable locking system, which enhances the rigidity of the fixing structure and effectively prevents the positioning membrane from loosening or shifting under complex external forces, such as sudden violent limb movements of the patient or bumps during transportation.

[0036] Please see Figure 1 - Figure 6 The positioning rod 34 is L-shaped, and the end of the positioning rod 34 is located on the inner wall of the movable groove 31. The positioning rod 34 and the movable groove 31 cooperate with each other, which is conducive to multi-directional coordinated positioning, making the position of the positioning block 3 in the limiting groove 11 more stable.

[0037] Please see Figure 1 - Figure 6 When the second spring 33 is not compressed, the rotating fixing block 32 moves away from the limiting groove 11. When the second spring 33 is compressed, the rotating fixing block 32 is close to the inner wall of the limiting groove 11. When the second spring 33 is not compressed, the rotating fixing block 32 leaves sufficient space for the initial placement and adjustment of the positioning film. When the second spring 33 is compressed, the rotating fixing block 32 clamps the fixing block 23, thus completing the fixation of the sliding plate 2.

[0038] The working principle of this utility model is as follows: When a medical positioning film is needed, the staff first guides the patient to lie flat on the matching positioning film placement plate 1. After the positioning film is heated and softened in a special device, it is quickly placed at the location where the patient needs to be positioned. The shape of the positioning film is initially adjusted according to the patient's body shape. Then, the two sides of the positioning film with positioning holes are inserted into the positioning film placement plate 1. The positioning holes of the positioning film are aligned with the limiting groove 11. The sliding plate 2 is pressed, causing it to drive the limiting block 21 through the positioning hole and the limiting groove 11 of the positioning film. During this process, the limiting block 21 with the fixing block 23 installed at the end will squeeze the positioning block 3, forcing the positioning block 3 to slide towards the inner wall of the limiting groove 11. As the positioning block 3 moves, the rotating fixing block 32 installed on the outer wall of the positioning block 3 will be subject to the limiting groove. The inner wall of 11 is squeezed and gradually rotates, wrapping and limiting the fixed block 23. As the positioning block 3 moves downward, the end of the positioning rod 34 located on the inner wall of the movable groove 31 will also be squeezed and move along the movable groove 31. When the positioning block 3 moves to the bottom of the limiting groove 11, the operator releases the pressure on the sliding plate 2. The positioning block 3 is pushed out of the limiting groove 11 by the second spring 33. At the same time, the positioning rod 34 will be guided by the movable groove 31 to limit the movement of the positioning block 3, so that it is stably held on the inner wall of the limiting groove 11. This allows the rotating fixed block 32 to clamp the fixed block 23 and limit the sliding plate 2. This allows the limiting block 21 to stably pass through the positioning hole and the limiting groove 11 of the positioning film, completing the limiting installation of the positioning film. The operator can then perform the final shaping work on the positioning film.

[0039] After the shaping of the positioning film is completed, the worker presses the sliding plate 2 again, causing it to drive the fixing block 23 to press the positioning block 3 again. As the positioning block 3 moves downward, the positioning rod 34 moves along the movable groove 31. When the positioning block 3 moves to the bottom of the limiting groove 11, the worker releases the pressure on the sliding plate 2. The positioning block 3 is pushed out of the limiting groove 11 by the second spring 33. At the same time, the sliding plate 2 is pushed out of the positioning film placement plate 1 by the first spring 22, so that the limiting block 21 can move away from the positioning hole and the limiting groove 11 of the positioning film, thus completing the unlocking of the positioning film and the positioning film placement plate 1.
