Detailed description of the invention
To make in detail the various embodiments of the utility model now and quoting, the example of these embodiments is shown in the accompanying drawings and is described below.Although this utility model will combine with illustrative embodiments and be described, should recognize, this description this utility model is restricted to those illustrative embodiments by not intended to be.On the contrary, this utility model is intended to not only cover these illustrative embodiments, and covers various selection forms, modification, the equivalent form of value and other embodiment that can be included within the spirit and scope of the present utility model that limited by claims.
Refer to Fig. 1 and Fig. 2, this utility model relates to the excision thing extraction element of the larger tumor of a kind of Minimally Invasive Surgery excision intraperitoneal, is particularly useful for taking out without omitting of the swollen thing of the laparoscopic surgery such as gynecological, surgery excision.This excision thing extraction element comprises: trocar sheath 1, handle 10, inner sleeve 2 and storage member.Handle 10 is arranged on the sidewall of trocar sheath 1, and this trocar sheath inside is smooth bore.One end of inner sleeve 2 is for implanting end (for extending in abdominal cavity of patients), and the other end is non-implantation end, i.e. free end.This inner sleeve 2 is set in trocar sheath 1, and the free end of inner sleeve is fixed with handle 8 by elastic cylindrical pin.
This storage member comprises: collecting bag 5, bracing wire 3 and two arc-shaped elastic steel plates 4.One end of each arc-shaped elastic plate 4 is connected by cutting ferrule 11 with the implantation end of inner sleeve 2 respectively, and the other end stretches into respectively and converges after the annular edge cover opening of this collecting bag 5, and this merging end is connected by a short sleeve (not shown).One end of bracing wire 3 is passed and is tied to form in the circumferential annular tubulose limit cover of bag mouth can the kink of pull, and the other end passes described trocar sheath 1 and stretches out from the inner chamber of this trocar sheath, this external part also can be provided with draw ring, be convenient to user and carry out reeling operation.In addition, described trocar sheath 1 and inner sleeve 2 are metal canula, and described arc-shaped elastic plate 4 is arc-shaped elastic steel plate, and these two arc-shaped elastic steel plates are semicircle, and combining can be annular.
Refer to Fig. 3 and Fig. 4, described collecting bag 5 is provided with two circular holes, and each circular hole is provided with check valve 7, and the opening direction of this check valve is towards collecting bag inner chamber, and namely check valve can only be opened in bag.Described check valve 7 is two valve check valves, is respectively used to insert cutting probe and visual probe.Insert visual probe from a valve check valve and inflate and make collecting bag 5 fully expansion formation working place, insert cutting probe from another one valve check valve.Cutting probe at visual lower pulverizing tumor body, and takes out external in the collecting bag 5 closed under visual probe monitors.Preferably, two circular holes on collecting bag 5 are crisscross arranged, and namely when casing pipe is vertically arranged, two circular holes are not on a horizontal plane, and adopt this kind of set-up mode, advantage is: be in staggered distribution, and are easy to operation.
In original state, namely under non-working condition, collecting bag 5 is rolled into thin tubular and two arc-shaped elastic steel plates 4 and is synchronously retracted into in metal jacket pipe 1, and this state as shown in Figure 2.
During use, user grasps handle 10, through stomach wall is nested, device head is sent into intraperitoneal, after fixed jacket duct member, with hand propelled handle 8, curling collecting bag 5 is released trocar sheath 1 completely together with two spring steel plates, launch collecting bag 5 bag mouth circular, the large volume storage bag mouth loading tumor body of 150 millimeters can be reached from flare up round diameter.This state as shown in Figure 3 and Figure 4.
After loading tumor body, spring steel plate 4 and stay cord 3 being pulled outwardly a segment distance makes collecting bag 5 bag mouth completely closed.This state as shown in Figure 5 and Figure 6.Insert pulverizing probe and visual probe respectively from two valve check valves, inflation dilatation, visual lower to external for tumor body pulverizing taking-up, remove in collecting bag totally, pull-out is popped one's head in.The collecting bag 5 of finding time being formed flake curlingly pulls out outside human body by nested hole with trocar sheath, inner sleeve, finally completes Wicresoft's resection operation of intraperitoneal larger volume tumor.
Above-described embodiment is for illustrative principle of the present utility model and effect thereof, but this utility model is not limited to above-mentioned embodiment.Those skilled in the art all without prejudice under spirit of the present utility model and category, in claims, can modify to above-described embodiment.Therefore protection domain of the present utility model, should cover as claims of the present utility model.
