Description

Technical Field

[0001] The present invention belongs to the field of urology, and particularly relates to a minimally invasive surgical protection device for pediatric urology. Background Art

[0002] In minimally invasive surgery for pediatric urology, for diseases such as urinary tract stenosis and urinary tract obstruction that cause difficulty in urination, it is often necessary to perform diagnosis or treatment through operations inside the urethra, such as injecting contrast agents, drugs or performing dilation through the urethra. Such surgical operations are delicate, and the physiological structure of the pediatric urethra is slender and the tolerance is poor. During the operation, thin-diameter instruments such as infusion needles are required to accurately enter the urethra.

[0003] Currently, traditional surgical protection measures mostly use fixed brackets or simple baffles, which are difficult to adapt to the changing body positions of children and the dynamic adjustment requirements during urethral operations. The protective cover cannot be adjusted flexibly, resulting in incomplete coverage of the protected area, and urine is easily splashed from the edge of the protective cover to the surgical wound surface or onto medical staff, increasing the risk of surgical area contamination and cross-infection, and further improvement is needed.

[0017] Advantages of the present invention:

[0018] 1. By driving the lifting block to slide up and down along the guiding rods through the electric cylinder on the bottom plate, the height of the lifting block can be quickly adjusted to adapt to the hip positions of children with different heights. The articulated design of the first rotating arm and the movable arm enables the protective plate to rotate around the side end of the lifting block. With the free bending of the second universal hose and the wire rope traction of the adjusting mechanism, the angle and position of the protective plate can be flexibly adjusted. At the same time, the protective cover is articulated through the second rotating arm and the first universal hose and can be bent at any angle. During use, the nurse manually and precisely adjusts the opening orientation and coverage range of the protective cover to meet the intraoperative dynamic adjustment requirements;

[0019] 2. Through the multi-dimensional adjustment of the first rotating arm, movable arm and adjustment mechanism, the protective plate can adjust the shielding range according to the changes in the child's body position or the needs of surgical operations, covering the side and upper part of the buttocks. Through the flexible bending of the first universal hose, the protective cover can accurately align the opening with the surgical site, forming a three-dimensional protective space, avoiding the edge gap caused by the fixed angle of the traditional protective cover, and realizing the shielding of urine splashing.

[0020] 3. In the camera mechanism, the camera can be finely adjusted in the up, down, left and right directions by sliding the T-shaped block in the T-shaped groove and screwing the threaded column in and out of the internal threaded cylinder. The height of the camera can be conveniently adjusted in cooperation with the infrared lamp, which facilitates the doctor to quickly align the camera with the position where the child needs surgery. By setting the display screen, the doctor can accurately locate without bending down to observe, reducing the risk of contamination caused by the body approaching the wound surface. The opening of the protective cover is aligned with the buttocks, directly intercepting the urine that may splash during the operation, and the protective plate blocks the lateral splashing. The two cooperate to form a closed protective area.

[0021] 4. The wavy design of the lying platform fits the child's body curve. The grip column is provided for the child to hold to stabilize the body position. The sponge block increases the comfort of lying prone, reduces the restlessness of the child, creates a stable environment for surgical operations, and is conducive to use.

[0042] Please refer to Figure 1 , in this embodiment, two guide rods are fixedly connected to the upper end of the bottom plate 3, and the lifting block 5 is slidably arranged on the side walls of the two guide rods. The guide rods provide stable guiding support for the up and down movement of the lifting block 5, ensuring that the lifting block 5 slides smoothly in the vertical direction when driven by the electric cylinder 4.

[0043] Embodiment 2: Please refer to Figure 5 , on the basis of Embodiment 1, the present application provides a technical solution: the adjusting mechanism includes a second universal hose 13, a fixed disk 14, a column 15, a top block 16 and a wire rope 17; one end of the second universal hose 13 is fixedly connected to the upper end of the lifting block 5, the other end of the second universal hose 13 is fixedly connected to the fixed disk 14, the column 15 is fixedly connected to the upper end of the protection plate 8, the top block 16 is fixedly connected to the upper end of the column 15, one end of the wire rope 17 is tied to the side wall of the column 15, and the other end of the wire rope 17 is tied to the side wall of the fixed disk 14. The second universal hose 13 can be bent freely to drive the fixed disk 14 to adjust the position. By pulling the column 15 with the wire rope 17, the inclination angle and height of the protection plate 8 can be flexibly changed. The top block 16 can limit the pulling direction of the wire rope 17, which is beneficial to quickly adjust the position of the protection plate 8.

[0044] Working principle: When in use, children lie on the prone platform 2 with their buttocks facing the lifting block 5. The wavy design on the upper end of the prone platform 2 fits the body curve of children. The grip columns 33 on both sides are for children to hold with both hands to enhance the body position stability. The sponge block 32 in the second groove 31 is used to reduce the discomfort of children lying prone for a long time;

[0045] Next, start the electric cylinder 4 to drive the lifting block 5 to slide up and down along the two guide rods on the bottom plate 3, adjust the height of the lifting block 5 so that the camera mechanism is aligned with the child's buttocks. The T-shaped block 25 can slide horizontally in the T-shaped groove 24, and at the same time, rotate the threaded column 27 to screw in and out of the internal thread cylinder 26, so as to adjust the shooting angle of the camera 28.
