Abstract

The invention relates to the field of peritoneoscope minimally-invasive surgery, in particular to a direct-inserting type peritoneoscope pneumoperitoneum-avoiding device. The shortcomings that an existing pneumoperitoneum-avoiding technology operation is small in space and bad in surgical field exposure can be overcome. The direct-inserting type peritoneoscope pneumoperitoneum-avoiding device comprises a support, a cantilever beam, a hanging umbrella and a sleeve. The technical scheme that an abdominal wall is pulled and lifted through umbrella leaves is used, a front abdominal wall is lifted, pulled and hung through the umbrella leaves, and the problem that the existing pneumoperitoneum-avoiding technology operation is not sufficient in space exposure is well solved.

Description

A kind of direct insertion laparoscope pneumoperitoneum-free device

Technical field:

The present invention relates to peritoneoscope minimally invasive surgery field, specifically a kind of direct insertion laparoscope pneumoperitoneum-free device.

Background technology:

Laparoscopic surgery has become the important modus operandi of the histoorgans such as liver, gallbladder, pancreas, spleen, stomach, intestinal, abdominal hernia, uterus and ovary as a kind of less invasive techniques.The tradition laparoscopic surgery utilizes CO ₂The pneumoperitoneum technology is made the operation technique space.Due to CO ₂Pneumoperitoneum has many harmful effects to breathing, blood circulation and Pregnant Fetus, and people have developed the laparoscopic surgery that various stomach wall suspension apparatus are exempted from pneumoperitoneum.But the existing pneumoperitoneum technology of exempting from, the Japanese Kirschner wire that comprises the island Medical Group agency of section is exempted from the pneumoperitoneum device, the gasbag-type suspension apparatus of Taiwan Fu-Hsing Chang, the fan formula retractor for abdominal wall of American I RVIN H, and the half-turn type drawing device of recent Japanese Y.Izumi report, the drag hook type of Taiwan I-Hui Wu report is exempted from the pneumoperitoneum device, all exists operative space to expose not enough major defect.Main cause is that existing stomach wall suspention pulling force of exempting from the pneumoperitoneum technology can make the bilateral stomach wall assemble to the centre, and the extruding intestinal tube is concentrated to the centre, causes operative space to diminish, narrow down; When muscular tension was larger, the operation technique space more can obviously dwindle.In peritoneoscope minimally invasive surgery field, exempt from main cause that the pneumoperitoneum technology can not get further developing and be to exempt from that pneumoperitoneum technology operative space is little, the visual area exposes poor problem and do not solved at all.

Summary of the invention:

The purpose of this invention is to provide a kind of direct insertion laparoscope pneumoperitoneum-free device, it can overcome the existing shortcoming that pneumoperitoneum technology operative space is little, the visual area exposes difference of exempting from.

The present invention achieves the above object by the following technical programs: a kind of direct insertion laparoscope pneumoperitoneum-free device comprises bracing frame, cantilever beam, suspention umbrella and sleeve pipe.Described suspention umbrella is comprised of umbrella leaf and umbrella frame, will suspend umbrella in midair and insert sleeve pipe, when the umbrella leaf touches lozenges in sleeve pipe, continues to promote the suspention umbrella, and the umbrella leaf will be supported by lozenges and be umbrella shape.

The technique effect that the present invention gives prominence to is:

The present invention exempts from the pneumoperitoneum technology and compares with existing, and material alterations is arranged, and described direct insertion laparoscope pneumoperitoneum-free device fully lifts front stomach wall at intraperitoneal by the umbrella leaf, has solved preferably the existing problem that pneumoperitoneum technology operative space exposes deficiency of exempting from.

The specific embodiment:

The invention will be further described below in conjunction with accompanying drawing.

Suspention umbrella rib (Fig. 2) is connected in the clasp mode with umbrella leaf (Fig. 3), and suspention umbrella (Fig. 5) is connected with cantilever beam by hinge, and cantilever beam is connected with bracing frame.mention front stomach wall, the approximately otch of 10mm is done at the place in annulus umbilicalis, insert sleeve pipe (Fig. 4) and reach intraperitoneal, to suspend umbrella (Fig. 5) in midair and insert sleeve pipe (Fig. 4), promote umbrella frame (Fig. 2) downwards, when umbrella leaf (Fig. 3) touches the inner lozenges of sleeve pipe (Fig. 4), continue to promote umbrella frame (Fig. 2), umbrella leaf (Fig. 3) will be supported gradually by the lozenges of sleeve pipe (Fig. 4), when the complete contact of lozenges of umbrella leaf (Fig. 3) and sleeve pipe (Fig. 4), umbrella leaf (Fig. 3) is strutted fully is umbrella shape (implementation procedure as shown in Figure 6), upwards lift sleeve pipe (Fig. 4), front stomach wall will be suspended up.Upwards pull umbrella frame (Fig. 2), umbrella leaf (Fig. 3) will move upward with umbrella frame (Fig. 2) and separate with sleeve pipe (Fig. 4).

Claims

1. direct insertion laparoscope pneumoperitoneum-free device, thereby utilize external force that front stomach wall is lifted or suspend in midair and cause the operation technique space, it is characterized in that: this device is comprised of bracing frame, cantilever beam, suspention umbrella and sleeve pipe, described suspention umbrella is comprised of umbrella leaf and umbrella frame, to suspend umbrella in midair and insert sleeve pipe, when the umbrella leaf touches lozenges in sleeve pipe, continue to promote the suspention umbrella, the umbrella leaf will be supported by lozenges and be umbrella shape.

2. direct insertion laparoscope pneumoperitoneum-free device according to claim 1, it is characterized in that: front stomach wall is fully lifted at intraperitoneal (under stomach wall) by umbrella leaf (planar), can thoroughly solve and originally exempt from the problem that pneumoperitoneum technology operative space exposes deficiency.
