Abstract
The invention provides a sealing piece of a puncture outfit. The sealing piece comprises a sealing body and a ring flange which is arranged around the sealing body and takes a connecting effect. The sealing body can be selectively opened and fully closed. A cross-shaped sealing port is arranged at the top of the external side of the sealing body. The extension lines of the cross-shaped sealing port are intersected with a transverse plane. The cross-shaped sealing port divides the sealing body into four special parts, wherein each part is of the shape of an outwards protruding triangular pyramid. The sealing piece of the puncture outfit has the beneficial effects that when a sewage collection bag passes through the sealing piece, since the sealing piece can be rapidly turned over and opened and the sealing port is much larger than the sealing port in the prior art, the sewage collection bag can penetrate through the sealing piece very easily; and after the sewage collection bag penetrates through the sealing piece, the sealing piece can very rapidly restore to the original position.
Description
Technical field
The present invention relates to a kind of perforator, relate in particular to a kind of sealing member for perforator.
Background technology
Perforator is a kind ofly to pierce through stomach wall and the operating theater instruments that enters the body cavity passage is provided for other operating theater instruments, belongs to a kind of Minimally Invasive Surgery apparatus.
Perforator generally includes as the sleeve assembly of other operating theater instruments admission passages and the puncturing lever in the described sleeve assembly.For transdermal, first cut epiderm skin with scalpel, then puncturing lever transdermal and enter body cavity.Exert pressure by the near-end to described puncturing lever, skin is passed at the tip that promotes described puncturing lever, until it enters body cavity.Perforator enters body cavity, extracts puncturing lever out, and sleeve assembly just can be used as the mis instruments passage of carrying out endo-surgical and splanchnoscopy operation.
At present, perforator uses a kind of " duckbill " black box usually.Disclose a kind of " duckbill " black box as Chinese patent CN200410092185, comprised a pair of relative valve member, it is closed when being subject to intra-abdominal pressure.After the sleeve assembly of perforator entered body cavity, due to the effect of abdominal pressure, it was sealing state that " duckbill " black box keeps closing; When having medical apparatus and instruments to be undertaken operating in body cavity by sleeve assembly, " duckbill " thus black box is subject to the thrust sector of medical apparatus and instruments to be opened and allows medical apparatus and instruments to pass through.And in prior art, " duckbill " black box takes out still that operation receives dirty bag must per os, when receiving dirty bag during by " duckbill " black box, the upset distortion of " duckbill " black box, this has increased to a certain extent receives the difficulty that dirty bag passes through from this " duckbill " black box; The more important thing is, the doctor uses larger pulling force, has increased to receive the impaired probability of dirty bag, has increased the risk of polluting the abdominal cavity.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of making and receive dirty bag pass smoothly the sealing member of perforator after operation is completed.
Purpose of the present invention will be achieved by the following technical programs:
A kind of outside top of described seal is provided with the seal of " a ten " font, and the extended line of the seal of described " ten " font and described transverse plane intersect; The seal of described " ten " font is divided into four identical parts with seal, each parts is the triangular pyramidal that outwards is convexly equipped with, the minimum range of described transverse plane is arrived to the distance of the transverse plane of described annular flange in the formed plane, summit of four triangular pyramidals of described four parts greater than the seal of described " ten " font, and arrives the ultimate range of described transverse plane less than the seal of described " ten " font.
Preferably, described each parts are the right angle trigonometry taper that outwards is convexly equipped with, and described seal is two of the bottom surfaces right-angle side of arbitrary described parts.
Beneficial effect of the present invention is mainly reflected in: when receiving dirty bag during through sealing member, because the seal can be overturn soon and opened, and seal opens much larger than prior art, can pass easily sealing member so receive dirty bag; When receiving after dirty bag passes sealing member, the seal can be returned to initial position again soon.
Description of drawings
Fig. 1 is the axonometric chart of sealing member of the present invention.
Fig. 2 is the front view of sealing member of the present invention, and this moment, seal was closed.
Fig. 3 is the left view of sealing member of the present invention.
Fig. 4 is the front view of sealing member of the present invention, and this moment, seal was opened.
The specific embodiment
As Figure 1-3, the invention provides a kind of sealing member of perforator, it comprises: seal 1 and the annular flange 2 that is arranged on its interconnect function on every side, and described seal 1 is optionally opened and is closed fully, and the upper surface of described annular flange 2 is positioned at a transverse plane X.Described seal 2 is convexly equipped with outside described transverse plane X-direction, the outside top of described seal is provided with the seal 3 of " a ten " font, the extended line of the seal of described " ten " font and described transverse plane X intersect, and namely four ends of the seal of described " ten " font are not in a plane.As shown in the figure, the described transverse plane X of centre-to-centre spacing of the seal of described " ten " font farthest, and then the far-end that is convexly equipped with of visible described seal is roughly a tip.
In conjunction with Fig. 2 and shown in Figure 3, the seal of described " ten " font is divided into four identical parts with seal, and each parts is the identical right angle trigonometry taper 4 that outwards is convexly equipped with.Specifically as shown in Figure 2, described seal is two of the bottom surfaces right-angle side of arbitrary described parts.The summit 5 of described right angle trigonometry taper 4 is by three muscle that outwards are convexly equipped with 6,7,8 crossing forming, and the existing effect of gaining in strength of these muscle increases the effect of bounce in addition, hereinafter will describe in detail.
Specifically as shown in Figure 3, the minimum range of described transverse plane is arrived to the distance of the transverse plane X of described annular flange in the formed plane, summit 5 of four right angle trigonometry tapers of described four parts greater than the seal of described " ten " font, and arrives the ultimate range of described transverse plane less than the seal of described " ten " font.
The underdraw work process of the seal of the below: when receiving dirty bag during through sealing member, the seal 3 of " ten " font of the seal namely can overturn soon from its center and open, form the opening 9 of a general square shape, as shown in Figure 4, the line of four ends of the seal of four of described opening 9 limit 10 difference described " ten " fonts.Because square opening 9 is more much bigger than a linear opening of prior art, the dirty bag of receiving like this can pass sealing member easily.When receiving after dirty bag passes sealing member, the seal can be returned to initial position again soon.Because the muscle 6,7 that three outwards is convexly equipped with, 8 triangular pyramidal setting, the center of the seal of " ten " font when causing being strutted upset can be subject to an inside restoring force all the time, makes seal can return to voluntarily initial sealing state.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
