Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a keloid treatment implantation needle fixing device with an integrated lead-containing shielding layer. Background Art

[0002] In the treatment of keloids, radiotherapy is widely used and is divided into external beam radiation and high-dose rate brachytherapy. Among them, the interstitial implantation irradiation method of brachytherapy is to implant a hollow needle tube into the subcutaneous tissue of a closed incision during surgery, and then introduce a step source for irradiation. In this treatment context, a keloid treatment implantation needle fixation device with an integrated lead-containing shielding layer plays an important role. It is an instrument used to assist in radiotherapy of keloids. The device is equipped with a precise reserved implantation needle channel for precise fixation of the implantation needle. Its main purpose is to stably fix the implantation needle during interstitial radiotherapy of keloid tissues, ensuring that the radiation source acts accurately on the keloid site through the implantation needle, and at the same time using the lead-containing shielding layer to reduce radiation to the surrounding healthy skin to ensure smooth treatment.

In addition, the damaged shielding layer can be replaced to reduce costs.

[0020] 2. The present invention drives the movable part to move backward by pressing the push rod, and squeezes the two first springs when the movable part moves backward. The two clamping parts slide in the fourth slide groove when the movable part moves backward. The two movable parts move to clamp and fix the insertion needle.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see the attached Figure 1 -Attached Figure 3An embodiment of the present invention provides a keloid treatment insertion needle fixing device with an integrated lead-containing shielding layer, including a fixing frame 1, two first slide grooves 7 are provided on the fixing frame 1 and the left and right sides, a first shielding layer 2 is slidably connected between the two first slide grooves 7 at the top, a second shielding layer 3 is slidably connected between the two upper and lower adjacent first slide grooves 7, an adhesive layer 4 is fixedly connected to the bottom of the fixing frame 1, two second slide grooves 11 are provided on the top and top of the inner wall of the fixing frame 1, five connecting parts 5 are slidably connected between the four second slide grooves 11, a channel 6 is provided on the front side of the five connecting parts 5, and a fixing component is provided in the five connecting parts 5, which is used to fix the insertion needle.

[0035] Specifically, the first shielding layer 2 and the second shielding layer 3 can be installed and disassembled through the first slide groove 7, which is convenient for replacing and cleaning the damaged shielding layer. The connector 5 slides in the second slide groove 11 to flexibly adjust the position of the connector 5 according to actual needs. The channel 6 on the connector 5 is used to insert the insertion needle to position and fix the insertion needle. The whole is attached to the patient's wound through the adhesive layer 4 at the bottom for treatment.

[0036] See attached Figure 9 The first shielding layer 2 and the second shielding layer 3 both include an aluminum plate layer 31 , and the top and bottom of the aluminum plate layer 31 are fixedly connected to the steel plate layer 30 .

[0037] Specifically, the aluminum plate layer 31 has good radiation shielding performance, and the steel plate layer 30 can enhance the overall mechanical strength, resist external impact, extend the service life, and improve the shielding effect.

[0038] See attached Figure 10 The adhesive layer 4 includes a supporting layer 32 , an adhesive layer 33 is fixedly connected to the bottom of the supporting layer 32 , and an antibacterial coating 34 is provided on the bottom of the adhesive layer 33 .

[0039] Specifically, the support layer 32 can provide a stable structural support for the entire adhesive layer, ensuring that the adhesive layer is not easily deformed during use. The adhesive layer 33 can make the adhesive layer firmly attached to the desired position, ensuring that the device will not be easily displaced during treatment. The antibacterial coating 34 can effectively inhibit the growth and reproduction of bacteria, reducing the risk of infection, especially in the case of long-term use or contact with the skin, which can reduce the adverse effects of bacterial growth on the skin.

[0040] See attached Figure 10 The support layer 32 is made of medical-grade polyurethane film, the adhesive layer 33 is made of butyl acrylate, and the antibacterial coating 34 is a nano-silver coating.

[0041] Specifically, the support layer 32 is made of medical-grade polyurethane film, which has good flexibility and biocompatibility, can adapt to different surface shapes and has little irritation to the skin. The adhesive layer 33 is made of butyl acrylate, which has high viscosity and low allergy, can ensure firm adhesion and is not prone to allergic reactions. The antibacterial coating 34 is a nano-silver coating with strong antibacterial properties, which can effectively inhibit bacterial growth and reduce the risk of infection.

[0042] See attached Figure 2 and attached Figure 4 The inner wall of the first shielding layer 2 is slidably connected with a moving block 27, and the rear side of the moving block 27 is fixedly connected with a second spring 26. The rear end of the second spring 26 is fixedly connected to the inner wall of the first shielding layer 2. Fifth sliding grooves 24 are opened on the left and right sides of the moving block 27. A limiting block 25 is slidably connected between the two fifth sliding grooves 24. The bottom of the limiting block 25 passes through and extends to the bottom of the first shielding layer 2. A pressing rod 8 is fixedly connected to the front side of the moving block 27, and the front end of the pressing rod 8 passes through and extends to the front side of the first shielding layer 2.

[0043] Specifically, the user presses the pressing rod 8 to drive the moving block 27 to move backward to squeeze the second spring 26. When the moving block 27 moves, it drives the limit block 25 to slide in the fifth slide groove 24. At this time, the limit block 25 is disengaged from the fixed groove 28 on the fixed frame 1. Then the first shielding layer 2 can be pulled to remove it. After the first shielding layer 2 is removed, the two second shielding layers 3 can be slid upward to remove it. After disassembly, all parts of the shielding layer can be thoroughly cleaned and carefully inspected to prevent long-term accumulation of dirt and potential minor damage that is not easy to detect, and the damaged shielding layer can be replaced to reduce costs.

[0044] See attached Figure 5 -Attached Figure 7 The fixed component includes a moving part 13, which is slidingly connected to the connecting part 5. Two fourth sliding grooves 23 are provided at the bottom of the moving part 13. The clamping parts 21 are slidingly connected in the two fourth sliding grooves 23. Two first springs 14 are fixedly connected to the rear side of the moving part 13. The rear ends of the two first springs 14 are fixedly connected to the inner wall of the connecting part 5. The front side of the moving part 13 is fixedly connected to the push rod 9. The front side of the push rod 9 passes through and extends to the front side of the connecting part 5.

[0045] Specifically, the user presses the push rod 9 to drive the movable part 13 to move backward. When the movable part 13 moves backward, the two first springs 14 are squeezed. When the movable part 13 moves backward, the two clamping parts 21 slide in the fourth slide groove 23. The two movable parts 13 move to clamp and fix the insertion needle, thereby fixing the two clamping parts 21, thereby realizing the fixation of insertion needles of different models.

[0046] See attached Figure 6 -Attached Figure 8The top of the moving member 13 is provided with an inclined groove 29, and a fixing rod 15 is provided inside the inclined groove 29. The top of the fixing rod 15 passes through and extends to the top of the connecting member 5, and the fixing rod 15 and the connecting member 5 are slidably connected.

[0047] Specifically, when the user operates the movable part 13 to move backward, the fixed rod 15 will slide in the inclined groove 29 on the movable part 13. At this time, the fixed rod 15 is lifted up by the movable part 13 and inserted into the limiting groove 12 at the top, thereby fixing the connecting part 5. When the fixed rod 15 is out of the limiting groove 12, the connecting part 5 can slide left and right in the fixed frame 1, so as to adapt to the position and shape differences of keloids of different patients and flexibly adjust the position of the connecting part 5 according to different situations.

[0048] See attached Figure 5 -Attached Figure 6 A rack 19 is fixedly connected to the top of the moving part 13, and a gear 20 is meshed with the right side of the rack 19. A ratchet 16 is fixedly connected to the top of the gear 20. The top of the ratchet 16 is rotatably connected to the inner wall of the connecting member 5. A pawl 17 is provided on the front side of the ratchet 16. The pawl 17 is rotatably connected to the inner wall of the connecting member 5. A tension spring 18 is fixedly connected to the front side of the pawl 17. The front end of the tension spring 18 is fixedly connected to the connecting member 5. The front side of the pawl 17 is fixedly connected to the toggle rod 10, and the front side of the toggle rod 10 passes through and extends to the front side of the connecting member 5.

[0049] Specifically, when the user operates to move the movable member 13, the rack 19 fixedly connected to the top of the movable member 13 moves accordingly, and the rack 19 drives the gear 20 meshing on the right to rotate, and the ratchet 16 fixedly connected to the top of the gear 20 rotates accordingly. The pawl 17 on the front side of the ratchet 16 is tightly fitted with the ratchet 16 under the action of the tension spring 18, thereby playing a fixing role. When adjustment is needed, push the toggle rod 10 to disengage the pawl 17 from the ratchet 16. At this time, the two first springs 14 on the rear side reset the movable member 13. At this time, the two clamping members 21 are separated to remove the insertion needle, and the fixing rod 15 falls into the inclined groove 29 to disengage the limit groove 12 at the top. At this time, the connecting member 5 can be freely adjusted to change the position of the channel 6.

[0050] See attached Figure 2 A fixing groove 28 is provided on the top of the fixing frame 1, and a limiting groove 12 is provided on the top of the inner wall of the fixing frame 1.

[0051] Specifically, the fixing groove 28 is used to fix the first shielding layer 2 when the first shielding layer 2 is installed, and the limit block 25 is inserted into the fixing groove 28. Since the first shielding layer 2 blocks the two second shielding layers 3, each shielding layer can be detached. The limit groove 12 is a plurality of holes that match the fixing rod 15, which is used to fix the connecting part 5 when the fixing rod 15 is inserted to prevent it from moving left and right.

[0052] See attached Figure 6 A third sliding groove 22 is provided at the bottom of the inner wall of the connecting member 5 , and both clamping members 21 slide in the third sliding groove 22 .

[0053] Specifically, the third sliding groove 22 provides a stable sliding track for the clamping member 21, ensuring the stability and accuracy of the movement of the clamping member 21, making the clamping operation more reliable and accurate.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
