Description

Technical Field

[0001] The utility model relates to the technical field of minimally invasive treatment devices, in particular to a multi-directional positioning minimally invasive treatment device for anal fistula. Background Art

[0002] Anal fistula is a common anorectal disease, usually caused by anal gland infection, surgical complications or trauma, forming an abnormal passage between the anus and rectum. Traditional treatments for anal fistula, such as incision and suturing, although effective to a certain extent, are often accompanied by greater trauma, postoperative pain and a long recovery period. In recent years, minimally invasive treatment of anal fistula has gradually become a mainstream option. By using endoscopes and other minimally invasive tools for precise positioning and treatment, trauma to patients is reduced and postoperative recovery time is shortened. Minimally invasive surgery has significant advantages in improving patient comfort and reducing postoperative complications, and is therefore accepted by more and more doctors and patients.

[0003] During minimally invasive treatment of anal fistulas, doctors typically use a variety of specialized tools and equipment to ensure surgical precision and effectiveness. Endoscopes are used to visualize the internal structure of anal fistulas in real time, helping doctors accurately determine the direction and branches of the fistula tract. Fistula probes are used to explore and determine the path of the fistula tract, especially in complex structures. Laser equipment is used to close the fistula tract, destroying diseased tissue with laser energy and promoting healing. Furthermore, working channels are required to provide a stable operating space and facilitate the flexible use of instruments. These tools work together to enable minimally invasive surgery to achieve precise treatment through small incisions.

[0004] However, during surgery for complex fistulas (such as horseshoe-shaped fistulas or fistulas with multiple branches), multiple probes are often required to explore the different fistula branches. Multi-directional exploration helps doctors fully understand the overall structure of the fistula and ensure that all diseased channels are effectively treated. However, the use of multiple probes carries the risk of wire entanglement, leading to confusion during surgery and affecting the progress and safety of the surgery. Currently, there is a lack of an effective device for positioning and managing multiple wires, which not only increases the complexity of the surgery but may also lead to misoperation or delays. In view of this, we propose a multi-directional positioning anal fistula minimally invasive treatment device. Utility Model Content

[0005] The purpose of the present invention is to provide a multi-directional positioning anal fistula minimally invasive treatment device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The multi-directional positioning anal fistula minimally invasive treatment device includes a fixing assembly that provides basic support for the entire device, ensuring that the device is stable and immobile during surgery to avoid surgical errors due to positional displacement. The fixing assembly includes a U-shaped clamping plate that is clamped and fixed to the edge of the operating table. The top of the U-shaped clamping plate is provided with a height adjustment assembly that allows the height of the entire device to be adjusted, so that the height of the probe wire can be adjusted, thereby allowing the probe wire to be suspended in the air to avoid affecting the operation of other surgical instruments.

The circular connecting rod is pressed into the circular connecting groove by the first clamping bolt, thereby fixing the relative position of the frame-shaped connecting block and the support vertical plate.

[0017] Preferably, a second clamping bolt is threadedly connected to the middle part of the top of the frame-shaped connecting block, and the threaded end of the second clamping bolt is abutted against the top of the strip plate. The position of the strip plate and the frame-shaped connecting block is fixed by the second clamping bolt, which makes it convenient for the staff to adjust the position of the strip plate.

The position of the strip plate 32 and the frame-shaped connecting block 30 is fixed by the second clamping bolt 33, which makes it convenient for the staff to adjust the position of the strip plate 32.

[0043] When using the multi-directional positioning anal fistula minimally invasive treatment device of this embodiment, first, fix the U-shaped clamping plate 10 to the edge of the operating table, and adjust the position of the pressure plate 12 by rotating the threaded rod 11, so that it moves upward to firmly clamp the U-shaped clamping plate 10 to the edge of the operating table, ensuring that the device is stable and immobile during the operation, avoiding position displacement affecting the surgical operation. Next, adjust the height of the entire device by adjusting the height component 2. A support vertical plate 21 is provided in the rectangular vertical tube 20. The support vertical plate 21 can be adjusted up and down so that the height of the probe wire is properly adjusted to ensure that the wire is suspended in the air, avoiding affecting the operation of other instruments during the operation. Then, the operation of the position adjustment member 3 includes a frame-shaped connecting block 30 and a strip plate 32. The strip plate 32 can be adjusted left and right relative to the frame-shaped connecting block 30. At the same time, the position adjustment member 3 itself can be rotated relative to the support vertical plate 21. The doctor can flexibly adjust the position of the strip plate 32 according to the needs of the operation to accurately position the wire and ensure that the direction and position of the probe wire meet the surgical requirements. Next, place the probe wire into the groove of the arc-shaped clamping block 43. The concave surface of the arc-shaped clamping block 43 is provided with a rubber lining 45, which provides additional friction to ensure that the wire does not slide or shift during use. The position of the threaded column 40 is adjusted by tightening the nut 44, and the circular positioning plate 41 is pressed against the strip plate 32 to fix the position of the wire and prevent the wire from moving during the operation. If multiple probe wires need to be used for multi-directional exploration, the number of positioning members 4 on the device can be adjusted according to the surgical requirements. The positioning member 4 can be disassembled and assembled as needed, and multiple probe wires can be fixed separately by multiple arc-shaped clamping blocks 43 to avoid wire entanglement and confusion. During the operation, the doctor can further adjust the position of the wire by adjusting the support vertical plate 21 and the position adjustment member 3 to ensure its accuracy during the operation. If the probe wire needs to be replaced or added, the positioning member 4 can be easily disassembled and assembled and its position adjusted. Through the above operations, the device can provide multi-directional positioning and wire management during the operation, helping doctors improve the accuracy and efficiency of the operation, reduce the risk of wire entanglement, and ensure the smooth progress of the operation.
