Because the elastic telescopic hole 121 has better telescopic elasticity, when the instrument channel assembly 13 is installed on the elastic soft channel seat body 12 through the elastic telescopic hole 121, the elastic telescopic hole 121 can tightly wrap the instrument channel assembly 13, so as to prevent the instrument channel assembly 13 from shifting or falling off in the operation process.

The utility model discloses a elasticity soft channel pedestal replaces traditional stereoplasm passageway pedestal, utilizes the high elasticity of elasticity soft channel pedestal, can effectively increase the radial range of motion of apparatus channel subassembly, set up to the detachable connected mode simultaneously between passageway pedestal and each apparatus channel subassembly, can select to install the apparatus channel subassembly of different specifications according to specific operation needs, make the product realize multi-functionalizing, the selectivity is strengthened, therefore the use flexibility and the result of use of product have been promoted greatly, the application scope of product is wider, use cost has been reduced to a certain extent, be favorable to the promotion of operation efficiency and operation safety; the elastic soft channel seat body and each instrument channel assembly are detachably connected through the elastic telescopic holes respectively, and the device is convenient to detach and install, simple in structure, safe and reliable.

It is understood that the material of the flexible channel body 12 includes, but is not limited to, silicone, medical rubber, polyurethane elastomer, etc.; the tubular channel body 2 is made of materials such as silica gel or plastic soft films.

Referring to fig. 2, preferably, in the present embodiment, the specific manner of rotatably connecting the elastic soft channel seat 12 and the upper end of the housing 11 is that the outer periphery of the elastic soft channel seat 12 is fixedly connected with the rotating member 3, the outer periphery of the rotating member 3 is movably annularly disposed inside the upper end of the housing 11, the outer periphery of the rotating member 3 is further fixed with the rotating handle 4, and the rotating handle 4 is movably sleeved outside the upper end of the housing 11. In the operation process, the operating personnel can further drive the rotating part 3 and the elastic soft channel seat body 12 to rotate through rotating the rotating handle 4, so that the specific position of the surgical instrument in the operation cavity penetrating through the inside of the instrument channel assembly 13 is adjusted, and the specific requirements in the operation are met.

Referring to fig. 5, preferably, the instrument channel assemblies 13 respectively include a hollow housing 131 and a cover 132 fixed to the top of the housing 131, a stopper 133 is annularly disposed on the outer periphery of the bottom end of the housing 131, the stopper 133 is located below the elastic telescopic hole 121, a through hole is disposed in the middle of the cover 132, and a sealing ring 134, a stopper piece 135 and a one-way sealing valve 136 are further telescopically disposed inside the housing 131 from top to bottom. The lower portion of sealing washer 134 is the toper, keeps off material piece 135 including annular disk and a plurality of rings of axial extension, and a plurality of rings of setting at intervals and along circumference evenly distributed, keep off material piece 135's the partial cover of ring and establish and install in the conical portion of sealing washer 134. It will be appreciated that the sealing ring 134 and the one-way sealing valve 136 are made of an elastic material such as rubber, and the sector ring of the striker plate 135 can expand the tapered portion due to its elasticity. The one-way sealing valve 136 is made of elastic materials such as rubber, and a cross-shaped slit is formed in a valve plate of the one-way sealing valve 136, so that surgical instruments can pass through the one-way sealing valve 136 and can wrap the surgical instruments, and the integral air tightness of the device is guaranteed.

In order to further enhance the flexibility of the product, in conjunction with fig. 3 and 5, it is preferable that at least one of the instrument channel assemblies 137 further includes an air inlet branch pipe 137, the air inlet branch pipe 137 is connected with the side of the housing 131, and the inside of the air inlet branch pipe 137 is communicated with the hollow part in the housing 131. It can be understood that, during the operation, intake pipe 111 is used for connecting the pneumoperitoneum machine to continuously provide carbon dioxide gas to tubular passage body 2 is inside, and carbon dioxide gas passes through outlet duct 112 after getting into tubular passage body 2 is inside and discharges, not only can take away the flue gas that a large amount of operations produced, can make the atmospheric pressure in the tubular passage body 2 maintain in stable range moreover, with the clear stability of ensureing the operation field of vision.
