Description

Technical Field

[0001] This invention belongs to the field of sealing joint technology, and specifically relates to a sealing joint for simulating surgical access. Background Technology

[0002] 3D printing technology, also known as rapid prototyping, is a technique that uses a digital model file as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. While it was previously used in mold making and industrial design for creating models, it is now increasingly being used for the direct manufacturing of some products.

[0003] Currently, surgical simulation access connectors on the market are mainly made of rigid materials, have poor mobility, complex structures, unstable sealing, and fixed dimensions, making them non-reusable. Therefore, a sealing connector for simulated surgical access is needed to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a sealing connector for simulating surgical access routes.

[0005] To achieve the above objectives, the present invention provides a sealing connector for simulating surgical access, comprising a vertically placed connecting plate, a through hole at the center of one side of the connecting plate, a first flange located at the through hole on the connecting plate, a sealing gasket located on the side of the first flange away from the connecting plate, a second flange located on the side of the sealing gasket away from the first flange, and a gland head, the gland head horizontally passing through the first flange, the sealing gasket, and the second flange, and the gland head fixing the first flange, the sealing gasket, and the second flange, wherein the through hole, the first flange, the sealing gasket, the second flange, and the gland head are arranged concentrically.

[0006] Furthermore, it also includes two locking washers, with the sealing washer located between the two locking washers, and the two locking washers and the sealing washer are fixed together by the gland head.

[0007] Furthermore, it also includes a number of fastening bolts. The first flange, the sealing gasket, and the second flange are all provided with a number of light holes that match the fastening bolts. The number of fastening bolts corresponds one-to-one with the number of light holes. The connecting plate is provided with screw holes that match the fastening bolts at the positions that correspond to the number of light holes.

[0008] Furthermore, the number of screw holes is four, and the number of optical holes is four.

[0009] Furthermore, the first flange, the second flange, and the gland are all made of polyacid emulsion.

[0010] Furthermore, the sealing gasket is made of silicone.

[0011] Furthermore, the material of the fastening bolt is 304 stainless steel.

[0012] The advantages of this invention are: the first flange, the sealing gasket, and the second flange are sequentially installed on a connecting plate on one side of the water tank using special adhesive. Then, the first flange, the sealing gasket, and the second flange are fixed together using a gland, which seals the through hole of the connecting plate. This ensures that when personnel practicing surgical approaches through simulation punctures through the through hole of the water tank's connecting plate, the liquid inside the water tank will not leak. Thus, the device has a simple structure, good sealing effect, high mobility, is reusable, and has low manufacturing and usage costs.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] Example 1

[0024] This embodiment provides, for example Figures 1-4 The sealing connector shown is for a simulated surgical approach and includes a vertically placed connecting plate 1. A through hole 2 is provided at the center of one side of the connecting plate 1. A first flange 3 is provided on the connecting plate 1 at the through hole 2. A sealing gasket 4 is provided on the side of the first flange 3 away from the connecting plate 1. A second flange 5 is provided on the side of the sealing gasket 4 away from the first flange 3. It also includes a gland 6, which horizontally passes through the first flange 3, the sealing gasket 4, and the second flange 5. The gland 6 fixes the first flange 3, the sealing gasket 4, and the second flange 5. The through hole 2, the first flange 3, the sealing gasket 4, the second flange 5, and the gland 6 are arranged concentrically.

[0025] In use, the first flange 3, the sealing gasket 4, and the second flange 5 are first installed sequentially on the connecting plate 1 on one side of the water tank using special adhesive. Then, the first flange 3, the sealing gasket 4, and the second flange 5 are fixed together using the gland 6, which seals the through hole 2 of the connecting plate 1. This ensures that when personnel practicing surgical approaches through simulation puncture through the through hole 2 on the connecting plate 1 of the water tank, the liquid in the water tank will not leak. Thus, the device has a simple structure, good sealing effect, high mobility, is reusable, and has low manufacturing and usage costs.

[0026] Furthermore, it also includes two locking washers 7, with a sealing washer 4 located between the two locking washers 7, and the two locking washers 7 and the sealing washer 4 are fixed together by a gland head 6.

[0027] By using locking gaskets 7 on both sides of the sealing gasket 4, the fixing effect of the gland head 6 can be increased when the gland head 6 fixes the first flange 3, the sealing gasket 4 and the second flange 5 together, thereby improving the stability of the device.

[0028] Furthermore, it also includes several fastening bolts 8, and several light holes 9 that match the fastening bolts 8 are opened on the first flange 3, the sealing gasket 4 and the second flange 5. The fastening bolts 8 and the light holes 9 correspond one-to-one. The connecting plate 1 has screw holes 10 that match the fastening bolts 8 at the positions that correspond to the light holes 9.

[0029] By using the fastening bolts 8 to engage with the screw holes 10 and the open holes 9, the fastening bolts 8 pass through the corresponding open holes 9 on the first flange 3, the sealing gasket 4, and the second flange 5, and are then inserted into the screw holes 10 on the connecting plate 1 for fixation. This improves the fixing effect and stability of the first flange 3, the sealing gasket 4, and the second flange 5 being installed on the connecting plate 1 in sequence. Furthermore, the fastening bolts 8 are threadedly connected to the connecting plate 1 through the screw holes 10, which simplifies the installation structure of the first flange 3, the sealing gasket 4, and the second flange 5, making installation and disassembly easier and further improving the mobility and reusability of the device.

[0030] Furthermore, the number of screw holes 10 is four and the number of plain holes 9 is four, which can ensure that the first flange 3, the sealing gasket 4 and the second flange 5 are fixed by fastening bolts 8 in all four directions, so that the first flange 3, the sealing gasket 4 and the second flange 5 are subjected to uniform force, and the service life of the first flange 3, the sealing gasket 4 and the second flange 5 is increased.

[0031] Furthermore, the materials of the first flange 3, the second flange 5, and the gland 6 are all polyacid emulsion.

[0032] Furthermore, the material of the sealing gasket 4 is silicone.

[0033] Furthermore, the material of fastening bolt 8 is 304 stainless steel.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
