Description

Technical Field

[0001] This utility model relates to the field of photodynamic medical device technology, and in particular to a fiber optic bracket for a photodynamic therapy device. Background Technology

[0002] Photodynamic therapy is a medical device that uses photodynamic therapy for treatment. It combines photosensitizers with specific wavelength light sources to selectively target diseased tissues, destroy diseased cells, and achieve therapeutic effects. It has the advantages of minimal trauma, low toxicity, good selectivity, and repeatable treatment. When used to treat tumors in the body such as cervical cancer and esophageal cancer, optical fibers are usually inserted into the body through interventional means such as endoscopes and catheters to accurately reach the tumor site. At this time, the parameters are set and the treatment is carried out. During the treatment process, which usually lasts for tens of minutes, the doctor holds the optical fiber continuously. Holding it for a long time can cause discomfort for the doctor, and if there are other patients to be treated, it will put a lot of burden on the doctor. To address the issue of holding it...

[0003] In the prior art, Chinese utility model patent CN210903330U discloses a solution for "a laser fiber optic support for gynecological laser treatment," which uses a U-shaped clamp to fix the fiber optic support to the bed. The fiber optic support can be moved and adjusted in four directions: up, down, left, and right. A laser fiber optic clamp is fixed at the top of the horizontal adjustment sleeve. Although this support can support the therapeutic laser fiber without requiring the doctor to hold it, thus reducing the doctor's workload, this support still has the following shortcomings:

[0004] 1) Limitations of U-shaped clips: The clamping position is limited by the bed and can only be clamped at the edge of the bed. Moreover, they may not be suitable for treatments other than gynecological ones.

[0005] 2) The adjustment method of the fiber optic bracket is inefficient. The operation requires repeatedly loosening and tightening the screws to adjust the up and down and left and right positions, which is especially troublesome when the fiber optic needs to be moved during treatment.

[0006] 3) The fiber optic clamp also needs to be tightened and loosened repeatedly for clamping and disassembly. If it is not completely disassembled and pulled out, it will contaminate the fiber optic bracket. If the upper clamp is completely disassembled and then installed, it will greatly increase the workload of disassembly and assembly. Utility Model Content

[0042] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0043] See Figure 1 , 2 As shown;

[0044] A utility model discloses a fiber optic support for a photodynamic therapy device, comprising:

[0045] A support rod that can make contact with the ground;

[0046] Fixed platform 1, used for mounting optical fiber 3, has its bottom movably connected to the top of the support rod via a first joint, allowing for omnidirectional rotation and positioning of the fixed platform 1; it also includes

[0047] The optical fiber 3 can pass through and be separated from the clamping device 2 of the fixed platform 1, and the clamping device 2 can clamp the fixed optical fiber 3.

[0048] Among them, a fixed plate 12 that can be raised and lowered is elastically connected to one side of the base 11 of the fixed platform 1 via a connecting rod assembly. This plate is used to cooperate with the positioning groove 111 on the base 11 to elastically hold or release the fiber optic support rod 23 of the clamping device 2.

[0049] Specifically, in this structure, the support rod can be placed on the ground, the bottom end of the support rod contacts the ground through the base 8, and the top end of the support rod is movably connected to the fixed platform 1 through the first joint. Preferably, the first joint is a universal damping ball joint 4, thereby realizing universal adjustment of the fixed platform 1. The upper surface of the base 11 of the fixed platform 1 is elastically connected to the fixed plate 12 through the connecting rod assembly. The fixed plate 12 can be raised or lowered relative to the base 11. In the free state, the fixed plate 12 and the base 11 are relative to each other to clamp the fiber optic support rod 23. When the clamping device 2 needs to be removed from the fixed platform 1, the fixed plate 12 is driven to rise, and a gap is formed between the fixed plate 12 and the base 11, and the fixed plate 12 releases the fiber optic support rod 23.

[0050] See Figure 2 As shown:

[0051] The fixed platform 1 includes a base 11, a hand pressure plate 13 disposed on one side of the base 11, a fixing plate 12 disposed on the other side of the base 11, and a connecting rod assembly;

[0052] The connecting rod assembly includes a spring 15 and a connecting rod 14;

[0053] The connecting rod 14 passes through the base 11 and connects the hand pressure plate 13 and the fixing plate 12. The spring 15 is sleeved on the outside of the connecting rod 14. The base 11 is provided with a receiving cavity in the mounting hole to accommodate the spring 15. The spring 15 is a compression spring. One end of the spring 15 abuts against the receiving cavity, and the other end abuts against the connecting rod 14.

[0054] In use, the spring 15 extends to drive the connecting rod 14 to reset the fixing plate 12 and hold the fiber optic support rod 23 with the positioning groove 111 on the base 11. When the fiber optic support rod 23 is released, the hand pressure plate 13 is pressed, the connecting rod 14 compresses the spring 15 and pushes the fixing plate 12 and the base 11 to create a gap for releasing the fiber optic support rod 23. The positioning groove 111 formed on the upper surface of the base 11 has a V-shaped structure.

[0055] See Figure 2 , 3 As shown:

[0056] To facilitate adjustment of the angle of use of the fixed platform 1, an adjustment handle 16 is fixedly connected to one side of the base 11. The use posture of the fixed platform 1 can be adjusted by adjusting the handle 16.

[0057] See Figure 4 As shown:

[0058] To facilitate adjustment of the height of the fixed platform 1, the support rod is a two-section folding rod structure;

[0059] Specifically, the support rod includes a first support rod 5 and a second support rod 7 fixedly connected to a base 8. The top end of the first support rod 5 is connected to the fixed platform 1 through a first joint, and the bottom end is connected to the second support rod 7 through a second joint 6. The first support rod 5 and the second support rod 7 can be folded at the second joint 6 position to adjust the overall height of the support rod.

[0060] The second joint 6 includes a joint adapter 62 connected to the first support rod 5 and the second support rod 7 respectively, a damping hinge 61 connecting the two joint adapters 62, and a decorative cover 63 fastened to the outside of the joint adapter 62.

[0061] See Figure 5-7 As shown:

[0062] Preferably, the fiber optic clamping device 2 includes a clamping body 22, a locking sleeve 21 threaded to one end of the clamping body 22, and a fiber optic support rod 23 threaded to the other end of the clamping body 22.

[0063] The clamping body 22 has a locking cavity 221. An elastic tube 24 is sleeved in the locking hole 231 at the top of the optical fiber support rod 23. One end of the locking sleeve 21 has a locking rod 211 that can extend into the locking cavity 221 and abut against the elastic tube 24, so as to squeeze the elastic tube 24 to deform and lock the optical fiber 3.

[0064] In the above technical solution, the working principle of the fiber optic bracket for a photodynamic therapy device provided by this utility model is as follows:

[0065] 1) First, push the hand pressure plate 13 to drive the connecting rod 14 to squeeze the spring 15 so that there is a sufficient gap between the fixed pressure plate 12 and the base 11. Hold the optical fiber clamping device 2 to put the optical fiber support rod 23 into the positioning groove 111 from the side. Release the hand pressure plate 13 to release the spring 15. The spring 15 extends and the fixed pressure plate 12 presses the optical fiber support rod 23 under the action of the spring force, so as to play a fixing role.

[0066] 2) Next, place the fiber optic bracket stably in a suitable position. Adjust the fixed platform 1 to a suitable height by adjusting the second joint 6 of the support rod. Then, use the adjusting handle 16 to rotate the universal damping ball joint 4 so that one end of the fiber optic support rod 23 of the fiber optic clamping device 2 is aligned with the part to be treated. Due to the existence of the damping hinge 61 of the second joint 6 and the universal damping ball joint 4, the fiber optic bracket can maintain a stable state after adjustment.

[0067] 3) Insert the optical fiber 3 through the through hole in the middle of the locking sleeve 21, and pass through the elastic tube 24 and the central hole of the optical fiber support rod 23 in sequence. Select the length of the optical fiber 3 extending from the optical fiber support rod 23 according to actual needs. After completion, the elastic tube 24 can be squeezed by rotating the locking sleeve 21. Due to the limitation of the clamping body 22 and the optical fiber support rod 23, the diameter of the central hole of the elastic tube 24 will be reduced, thereby clamping the optical fiber 3, realizing soft clamping, and preventing damage to the optical fiber.

[0068] 4) Fiber 3 starts to emit light for treatment. During the treatment, medical staff do not need to hold the fiber for a long time. After treating one area, if it is necessary to treat the next area, the position can be adjusted by holding the adjustment handle 16. The fiber 3 can be loosened by locking sleeve 21 to change the length of fiber extension and then clamped back.

[0069] 5) After treatment, pull the hand pressure plate 13 and take out the fiber optic clamping device 2 from the side. The fiber optic cable and the fiber optic clamping device 2 can be cleaned and disinfected separately. For ease of use, the fiber optic clamping device 2 can be made of low-cost disposable environmentally friendly materials, which eliminates the manpower and time costs of disassembly, cleaning and disinfection.

[0070] Beneficial effects: The fiber optic support of this photodynamic therapy device improves adaptability to different treatment needs and usage environments through the floor-mounted support; the combination of the damped universal ball joint and the two-section support rod allows doctors to conveniently and quickly adjust the position of the fiber optic cable at any time during treatment; the fiber optic clamping device only requires one knob to clamp and release the fiber optic cable, and it is designed to be separate from the fiber optic support, so it will not contaminate the fiber optic support. The clamping device can be disinfected separately. Furthermore, the fiber optic clamping device can be made into a disposable consumable, providing convenience for doctors.

[0071] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
