As embodiment, there is the embossing portion 330 of a plurality of lines within the scope of the predetermined radii centered by instrument enters hole 310, be formed at the upper surface of over cap 300.When operation tool is when import tool enters hole 310, embossing portion 330 has a plurality of lines, contacts but not face contact, and then reduce frictional force to form with the point of operation tool.

As embodiment, the high thickness part 340 with the high thickness area within the scope of the predetermined radii centered by instrument enters hole 310 is formed on the upper surface of over cap 300.

High thickness part 340 has the thickness that is greater than remainder; and therefore have intensity higher than remainder (that is; the periphery 340 ' of over cap 300); and accordingly; when mobile, when import tool enters the operation tool in hole 310, what have that instrument enters hole 310 can be by more easily moving with the random variation of the periphery 340 ' of the integrated softness of operation tool seemingly compared with thickness portion 340.

As embodiment, compared to the remainder of high thickness part 340, having increases the support enhancing portion 341 of thickness and can further be formed in high thickness part 340, to increase the support force of operation tool in radius closely.

As shown in figure 20; over cap 300 is installed on instrument entrance 400 securely; and when coupling ring 350, be coupled to fixture outside, and the fixture 320 that is positioned at over cap 300 lower ends is when embedded by the top of instrument entrance 400, over cap 300 is securely in insertion tool entrance 400.

Yet over cap 300 can be revised with distinct methods by the fixed form that couples ring 350 within the scope of the Change In Design of embodiment, and be for the ease of showing embodiment in the structure of the instrument entrance 400 shown in Figure 20.Therefore, should be appreciated that the structure that over cap 300 is installed on instrument entrance 400 is wherein not limited to this.

If over cap 300 is bonded to instrument entrance 400, over cap 300 around and the upper end of patch tool entrance 400, and then the surface, inside of over cap 300 separates instrument entrance 400 with predetermined interval, to form predetermined boundary space S in over cap 300.This boundary space S can be as the space of the random variation for the protection of lid 300.

Figure 21 to 23 figure is the exemplary schematic diagram according to the mode of operation of over cap of the present invention, and the operation that is installed on the over cap 300 in instrument entrance 400 according to the present invention will be described in down.

First; if operation tool conductor (not shown) is intactly installed in the surgical hole of sufferer; many operation tool T are through import tool entrance 400, and then entering behind hole 310 through instrument, first operation tool T are directed on the upper surface of over cap 300.

At this; when operation tool T is when guiding; the upper surface of operation tool T and over cap 300 contacts with each other; and the upper surface that is contacted with over cap 300 is put by the embossing portion 330 that enters the surrounding in hole 310 due to operation tool T by the instrument of being formed at, frictional force therefore reduces and operation tool T can more easily guide.

Figure 21 shows the state of guiding operation tool T completely.

In addition, Figure 22 and Figure 23 Figure 23 show the many mobile status of operation tool T of guiding according to operation process, and the operation tool T through guiding as shown in the figure moves towards many directions in intra-operative.

Then; when mobile operation tool as shown in Figure 22 and Figure 23 Figure 23; because over cap 300 also moves; and the strength producing while being simultaneously subject to mobile operation tool T and produce deformation; even if instrument enters hole 310 and still do not produce gap when mobile operation tool T; and remain attached to operation tool T, and accordingly, at the gas of abdominal part, can avoid sewing.

That is; when if operation tool T moves; this identical external force is transferred to and comprises the high thickness part 340 that enters hole 310 around the instrument of operation tool T; and the periphery 340 ' with the over cap 300 of low thickness is out of shape by this externally applied forces easily, makes to comprise instrument and enter the high thickness part 340 in hole 310 just like be one of the forming and move with operation tool T.Therefore, even when operation tool T needs at random and by different way to move because of operation, operation tool T and enter hole 310 around the instrument of operation tool T and keeps constantly fitting mutually, and avoid Leakage Gas simultaneously.

Mode accordingly, because over cap 300 according to the present invention can prevent the gas leakage in abdominal part effectively, in the middle of operation implementation process, directly supplements and the inconvenient problem of injecting gas can achieve a solution, and then guarantees more successfully to perform the operation.

Although exemplary embodiments of the present invention has been described in this, category of the present invention is not limited to embodiment and graphic content, and should comprise the impartial structure that having of association area in the category of the present invention institute of conventionally knowing the knowledgeable revises or changes.
