Description

Technical Field

[0001] This utility model relates to a fixing device, and more particularly to an auxiliary fixing device for sampling. Background Technology

[0002] Pediatric tumor biopsy refers to the process of obtaining tumor tissue samples through puncture techniques during the diagnosis of pediatric tumors. This is a commonly used diagnostic method aimed at determining the nature (benign or malignant), type, and biological characteristics of the tumor. It is characterized by safety, accuracy, minimal invasiveness, and painlessness, meaning that characteristic tumor information can be obtained without surgery. It is relatively safe and efficient, reducing the risks of surgery, and is also minimally invasive, has a fast recovery time, low cost, good results, and high accuracy.

[0003] Pediatric tumor biopsy sampling assistance fixation devices are medical devices specifically designed for children. They are used to assist doctors in more accurately controlling the position of the sampling needle during tumor biopsies, thereby improving sample quality and reducing trauma to the child. Children often exhibit behaviors such as crying, resistance, and fear during medical treatment, so it is necessary to quickly determine the tumor sampling location. However, existing pediatric tumor biopsy sampling assistance fixation devices have the drawback of not being flexible enough in adjusting the depth and angle of the sampling needle. That is, it is necessary to repeatedly move the entire device to ensure that the sampling needle is aligned with the required sampling location. Repeated operations may bring more psychological stress and physical discomfort to children.

[0004] Therefore, it is necessary to design an auxiliary fixing device for sampling to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the drawbacks of existing devices that require repeated movement of the entire device to ensure that the sampling target is aligned with the desired sampling position, and which may cause more psychological stress and physical discomfort to children with multiple operations, the technical problem to be solved is to provide an auxiliary fixing device for sampling.

[0006] The technical solution is as follows: A sampling auxiliary fixing device includes a base, a soft pad, a rotating shaft, a torsion spring, an elastic band, a fixing rod, a locking block, a support frame, a first threaded rod, a fixing block, and a second threaded rod. A soft pad is fixedly connected to the middle of the base. Rotating shafts are rotatably connected to the front and rear sides of the right side of the base. Torsion springs are fixedly connected between the front and rear ends of each rotating shaft and the right side of the base. An elastic band is fixedly connected to the top of each rotating shaft. The right side of each elastic band extends out of the top right side of the base. A fixing rod is fixedly connected to the left side of each elastic band. Two locking blocks are fixedly connected to the front and rear sides of the left side of the top of the base. The front and rear ends of each fixing rod are engaged with the locking blocks. A support frame is slidably connected to the middle of the top of the base. First threaded rods are threadedly connected to the left and right sides of the support frame. The first threaded rods are threadedly connected to the support frame. A fixing block is slidably connected to the middle of the support frame. Second threaded rods are threadedly connected to the top left and right sides of the fixing block.

[0007] Furthermore, it also includes a third threaded rod, which is threadedly connected to the rear top of the fixing block, and the third threaded rod is rotatably connected to the support frame.

[0008] Furthermore, it also includes a backing cloth, Velcro tabs and Velcro closures. Velcro tabs are fixed to the top left and right sides of the support frame. Velcro closures are locked to the back of the Velcro tabs and Velcro closures are fixed to the back of the Velcro closures. A backing cloth is fixed to the back of the Velcro closures.

[0009] Furthermore, the bottom of the base is fixed with anti-slip rubber.

[0010] Furthermore, the cushion blocks are made of polyurethane foam.

[0011] Furthermore, the cover can be repeatedly removed and washed.

[0012] The present invention has the following advantages: 1. The present invention fixes the sampling needle by means of the cooperation of the first threaded rod, the fixing block and the second threaded rod, etc. At the same time, the position and height of the sampling needle can be adjusted appropriately according to the location of the tumor, which effectively enhances the flexibility of adjusting the sampling needle and reduces the psychological pressure and physical discomfort of children.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example: An auxiliary fixing device for sampling, such as Figures 1-4 As shown, the system includes a base 1, a soft pad 2, a rotating shaft 3, a torsion spring 4, an elastic band 5, a fixing rod 6, a locking block 7, a support frame 8, a first threaded rod 9, a fixing block 10, and a second threaded rod 11. The soft pad 2, made of polyurethane foam, is mechanically fixed to the middle of the base 1. Rotating shafts 3 are rotatably connected to the front and rear sides of the right side of the base 1. Anti-slip rubber is adhered to the bottom of the base 1 using adhesive. Torsion springs 4 are fixed to the front and rear ends of the two rotating shafts 3 and the right side of the base 1. Elastic bands 5 are mechanically fixed to the top of the two rotating shafts 3. Both elastic bands 5 extend from the top right side of the base 1. Both elastic bands 5 are mechanically fixed with fixing rods 6 on the left side. Both the front and rear sides of the top left side of the base 1 are connected by screws to two locking blocks 7. Both the front and rear ends of the two fixing rods 6 are engaged with the locking blocks 7. A support frame 8 is slidably connected to the top middle of the base 1. The left and right sides of the support frame 8 are threadedly connected to the first threaded rods 9. The first threaded rods 9 are threadedly connected to the support frame 8. A fixing block 10 is slidably connected to the middle of the support frame 8. The top left and right sides of the fixing block 10 are threadedly connected to the second threaded rods 11.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a third threaded rod 12, a baffle 13, a Velcro 14, and a Velcro 15. The third threaded rod 12 is threadedly connected to the top rear side of the fixing block 10. The third threaded rod 12 is rotatably connected to the support frame 8. The left and right sides of the top of the support frame 8 are connected to the Velcro 14 by pins. The Velcro 14 is locked to the Velcro 15 at the rear. The baffle 13 is cured to the rear of the Velcro 15 by hot melt adhesive. The baffle 13 can be repeatedly disassembled and cleaned.

[0022] When the device is needed, medical staff should prepare the sampling needle in advance, then take out the device and place it on a clean table. Next, the medical staff should rotate the two second threaded rods 11 clockwise, causing them to move closer to the first threaded rod 9 on the same side. This increases the distance between the two second threaded rods 11. The medical staff should then hold the sampling needle firmly with one hand and place it between the two second threaded rods 11. The height at which the sampling needle should be clamped should be adjusted so that, in the initial clamping state, the needle tip is higher than the bottom of the support frame 8, to avoid accidental puncture wounds to the child when securing their arm. Then, the other hand... The two second threaded rods 11 are rotated counterclockwise, causing them to move away from the first threaded rod 9 on the same side. This allows the two second threaded rods 11 to work together to clamp the sampling needle. Then, the medical staff lowers the cover 13 vertically to block the sampling needle, preventing the child from experiencing strong psychological fear and resistance upon seeing it. After these preparations are complete, the medical staff removes the fixing rod 6, so it is no longer held in place by the locking block 7. Next, the medical staff places the child's arm on the soft pad 2 and adjusts the position where the sampling needle will be fixed according to the location of the sampling on the child's arm. Once the child's arm is confirmed to be in place, the medical staff proceeds with the sampling. After the child's arm is secured, medical staff adjust the elastic band 5 according to the arm's thickness to ensure it fits snugly against the arm. At this point, the rotating shaft 3 rotates, causing the torsion spring 4 to deform. The fixing rod 6 is then engaged with the locking block 7, securing the child's arm with the two elastic bands 5. Next, the sampling needle position is adjusted as needed. Because each child's arm is of varying thickness and the initial position of the sampling needle is relatively high, a second adjustment is required. This involves rotating the two second threaded rods 11 clockwise again, moving them closer to the first threaded rod 9 on the same side. This adjustment is done by rotating the two second threaded rods 11 clockwise again. Rotate the two second threaded rods 11 to loosen the sampling needle. Then adjust the height of the sampling needle. Once the height is determined, rotate the two second threaded rods 11 counterclockwise to fix the sampling needle. Finally, medical staff use the sampling needle to collect tissue samples from the tumor site. After successful sampling, repeat the above steps of rotating the two second threaded rods 11 clockwise to remove the sampling needle. Then remove the tumor tissue sample from the sampling needle and place it in the designated container. At this point, the tumor tissue sample collection is complete. Next, medical staff disengage the fixing rod 6 from the locking block 7. At this point, the torsion spring 4 returns to its original position. Then, extend the child's arm out of the soft pad block 2.

[0023] Because the location of tumors on different children's arms varies, after the child's arm is immobilized, medical staff can loosen the two first threaded rods 9 by rotating them clockwise, thus freeing the support frame 8 from fixation. Then, the medical staff can push the support frame 8 forward or backward, causing the sampling needle on it to move forward or backward, positioning it to correspond to the location of the tumor on the child's arm. Simultaneously, the medical staff can also rotate the third threaded rod 12 clockwise, causing it to move the fixing block 10 to the left, which in turn moves the sampling needle to the left. When the third threaded rod 12 is rotated counterclockwise... The third threaded rod 12 drives the fixing block 10 to move to the right, and the fixing block 10 drives the sampling needle to move to the right, so that the sampling needle on the support frame 8 is more accurately positioned to the sampling location. After the position of the support frame 8 and the sampling needle is determined, the two first threaded rods 9 are rotated counterclockwise to fix the support frame 8. Then the above sampling steps for tumor tissue samples can be repeated. When the cover 13 is soiled, the medical staff only need to separate the Velcro 14 and the Velcro 15 to remove the cover 13. Then the medical staff can replace it with a new cover 13, or wash and dry the soiled cover 13 and reuse it.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
