Description

Technical Field

[0001] The utility model relates to a hinge-type channel device for single-port surgery, belonging to the field of medical devices. Background Art

[0002] When performing abdominal surgery, after puncturing the abdomen, an instrument channel needs to be placed in the puncture hole, and surgical instruments can perform surgical operations through the instrument channel. Currently, most instrument channels are made of silicone material. After deforming the surgical instrument channel by pinching and placing it into the abdominal cavity through the puncture hole, it will automatically return to its original shape. Since it is made of silicone material, the instrument channel will also be deformed during the operation, unable to support the surgical instruments, which is not conducive to the normal progress of the operation.

When the left channel outer shell and the right channel outer shell are closed, an instrument channel is formed.

[0005] Further, a left hinge seat is arranged in the middle of the left housing, a right hinge seat is arranged in the middle of the right housing, and the left hinge seat and the right hinge seat are hinged through the hinge shaft.

[0006] Further, a sealing gasket is arranged on the left channel outer shell or the right channel outer shell. When the left channel outer shell and the right channel outer shell are closed, the sealing gasket is located between the left channel outer shell and the right channel outer shell.

[0007] Further, sealing protrusions are arranged on the sealing gasket, and sealing concave holes are arranged on the left channel outer shell or the right channel outer shell, and the sealing protrusions are located in the sealing concave holes.

[0008] Further, the material of the sealing gasket is silicone.

[0009] Further, the materials of the left housing and the right housing are iron, stainless steel or plastic.

[0010] Further, when the left channel outer shell and the right channel outer shell are closed, a sealing seat is installed at the end of the instrument channel.

[0011] Further, surgical instruments are arranged on the sealing seat.

[0012] Compared with the prior art, the utility model has the following advantages: The hinge-type channel device for single-port surgery is formed by hinging a left housing and a right housing through a hinge shaft. The left housing and the right housing are made of iron, stainless steel or plastic. After the instrument channel is formed, it can avoid deformation and can support surgical instruments, which is more conducive to the smooth progress of the surgery.

[0026] The hinge-type channel device for single-hole surgery in this embodiment includes a left housing 1, a right housing 2, and a hinge shaft 3. The left housing 1 and the right housing 2 are hinged by the hinge shaft 3, and an instrument channel 5 is formed between the left housing 1 and the right housing 2. The materials of the left housing 1 and the right housing 2 are iron, stainless steel, or plastic.

[0027] In this embodiment, the upper part of the left housing 1 is a left channel outer shell 13, the lower part of the left housing 1 is a left support leg 12, the upper part of the right housing 2 is a right channel outer shell 23, and the lower part of the right housing 2 is a right support leg 22. When the left channel outer shell 13 and the right channel outer shell 23 are closed, an instrument channel 5 is formed. A sealing seat 6 is installed at the end of the instrument channel 5, and a surgical instrument 7 is provided on the sealing seat 6. A left hinge seat 11 is provided in the middle of the left housing 1, and a right hinge seat 21 is provided in the middle of the right housing 2. The left hinge seat 11 and the right hinge seat 21 are hinged by the hinge shaft 3.

[0028] In this embodiment, a sealing gasket 4 is provided on the left channel outer shell 13 or the right channel outer shell 23. When the left channel outer shell 13 and the right channel outer shell 23 are closed, the sealing gasket 4 is located between the left channel outer shell 13 and the right channel outer shell 23. A sealing protrusion 41 is provided on the sealing gasket 4, and a sealing concave hole 42 is provided on the left channel outer shell 13 or the right channel outer shell 23. The sealing protrusion 41 is located in the sealing concave hole 42. The material of the sealing gasket 4 is silicone.

[0029] Specifically, the hinge-type channel device for single-hole surgery is composed of two semi-circular left housing 1 and right housing 2 hinged by a hinge shaft 3. The two left housing 1 and right housing 2 are combined into a flipable hinge-type structure by a preset pin. When in use, after puncturing the human skin layer 8 in the abdomen, when the left channel outer shell 13 and the right channel outer shell 23 are opened (such as Figure 2As shown in the figure), the left support foot 12 and the right support foot 22 can be inserted into the abdominal cavity through the puncture hole in the closed state. After the left support foot 12 and the right support foot 22 enter the abdominal cavity, by controlling the left channel housing 13 and the right channel housing 23, the left support foot 12 and the right support foot 22 can be expanded in the abdominal cavity, and when the left channel housing 13 and the right channel housing 23 are closed (as Figure 4 shown), an instrument channel 5 is formed. When the sealing seat 6 is installed at the end of the instrument channel 5 (as Figure 5 shown), and at the same time the surgical instrument 7 is installed on the sealing seat 6 and passes through the instrument channel 5 (as Figure 6 shown), the operation can be carried out. The air leakage of the instrument channel 5 can be prevented by the provided sealing gasket 4 and sealing seat 6.
