However, the membranous instrument channel and the movable instrument operating platform are of split structures and need to be manufactured respectively through two different dies, so that the manufacturing cost is high, the structure is relatively complex, and after two different components are compounded, the sealing problem between the membranous instrument channel and the movable instrument operating platform and the sealing problem between the membranous instrument channel and the surgical instrument need to be solved, and if the two different components are not properly processed, the air leakage phenomenon is easily generated, and the working reliability of the device is further influenced. In addition, the membrane instrument channel helps to achieve sealing of the laparoscopic surgical instrument relative to the bare instrument directly through a simple sealing structure, since the outer diameter of the membrane instrument channel must be significantly increased compared to the bare instrument outer diameter, the solution of helping to achieve sealing function through the membrane instrument channel is significantly deficient compared to the bare instrument directly through a simple sealing structure when the instruments need to be brought closer together to provide a larger operating angle.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 5, the sealing cap of the sealing device for laparoscopic surgery of the present embodiment includes a sealing cap body 1, and the sealing cap body 1 is a flexible member formed integrally, for example, silicone rubber, polyurethane, etc. The sealing cover body 1 comprises a cover top 11 and an annular wall 12 extending downwards from the periphery of the cover top, the cover top 11 is circular, and 5 operation holes capable of self-sealing are formed in the cover top 11. In this embodiment, the operation hole is a counterbore 2, wherein 1 counterbore 2 is located in the center of the top cover 11, and the other 4 counterbores 2 are evenly distributed around the central counterbore. The counter bore 2 of the embodiment is a round hole and is used for forming an instrument channel, the bottom of the counter bore 2 is provided with a cut 3 for a surgical instrument (not shown) to pass through, and the self-sealing of the operation hole is realized through the cut 3.

The cut 3 comprises a central cutting point 31 at the bottom of the counterbore 2 and cutting edges 32 distributed in a scattered manner from the central cutting point from the inside to the outside, so that the cut 3 can be opened to the surroundings. The cutting edges 32 of the present embodiment have 4 strips and are distributed in a cross shape, and correspondingly, the cuts 3 form cross-shaped cuts. The inner section of the cutting edge 32 forms a cutting edge 321, namely the inner side of the bottom of the counter bore 2 is cut off, the outer section of the cutting edge 32 forms a strip-shaped groove 322, namely the outer side of the bottom of the counter bore 2 is not cut off, the strip-shaped groove 322 of the embodiment is arranged on the inner bottom surface of the counter bore 2, namely the opening of the strip-shaped groove 322 faces the top of the sealing cover body 1. An annular reinforcing rib 21 is formed on the outer bottom surface of the counter bore 2, the joint of the cut edge 321 and the strip-shaped groove 322 is arranged at the position corresponding to the annular reinforcing rib 21, and the annular reinforcing rib 21 passes right below the joint of the cut edge 321 and the strip-shaped groove 322 by taking the direction indicated by the arrow B in fig. 5 as the upward direction. Set up annular strengthening rib 21 after, can avoid incision 3 to be excessively opened, make open incision 3 have good bounce-back simultaneously, when surgical instruments passes through incision 3, can hold the apparatus outer wall tightly better, avoid producing gas leakage phenomenon between apparatus and the incision 3, ensure sealing device's leakproofness. In addition, the lower peripheral wall of the counter bore 2 forms an inner convex part 22 which is convexly arranged inside the counter bore 2, the outer end of the strip-shaped groove 322 is close to the corresponding inner convex part 22, and the inner convex part 22 not only enables the structure of the counter bore 2 to be firmer, but also is beneficial to the instruments to smoothly pass through the opening positioned at the central part and not to abut against the blind end at the corner of the bottom part to cause the instruments not to pass through.

When the surgical instrument passes through the incision 3, the incision 3 is opened to hold the outer wall of the instrument tightly, so that air leakage at the incision 3 is avoided. Particularly, through the structures of the annular reinforcing ribs 21 and the strip-shaped grooves 322, the notch 3 can be in closer contact with the outer wall of the instrument, and the air leakage prevention effect is better. When no surgical instrument is passed through the incision 3, the respective cutting edges 32 of the incision 3 are reset and the cutting edges 32 are closed, so that the incision 3 achieves a self-sealing effect.

As shown in fig. 2 and 5, a coupling structure for coupling with the lower assembly 41 of the sealing device 4 for laparoscopic surgery is formed on the annular wall 12. Specifically, the annular wall 12 includes an upper annular wall 121 and a lower annular wall 122, the outer diameter of the lower annular wall 122 is smaller than the outer diameter of the upper annular wall 121 to form a step between the upper annular wall 121 and the lower annular wall 122, an annular rib 123 on the inner peripheral wall of the lower annular wall 122, and the lower portion of the seal cover is mounted on the lower module 41 through the annular rib 123.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be modified or improved, for example, the number of the counter bores 2 is not limited to 5, the cut edges 32 of the cut 3 are not limited to 4, and these are all considered as the protection scope of the present invention.
