Abstract
The utility model relates to an apparatus for expanding abdominal wall for peritoneoscope needing no air sac, which mainly solves the problems that the apparatuses needing no air sac in the present peritoneoscope operations have poor exposure of visual field in operation and inconvenient operation. Four heterotype support arms of the apparatus for expanding abdominal wall for peritoneoscope needing no air sac are movably connected via a central shaft and a shaft hole, and a support structure which can be folded and unfolded freely is formed; the entering abdomen end of each support arm is connected with a support bar, and wherein, an elastic pulling net is arranged between the lower ends of the two support bars positioned at the lower part. When using, first of all the four support bars are folded and enter abdominal cavity via a hole on abdomen, and then the handle ends of the four support arms are folded and arranged in the handles; at this time, the lower bottom surface of the visual field of the peritoneoscope is formed via the elastic pulling nets on the two support bars at the lower part, abdominal wall is supported up via the two support bars at the upper part, thus a larger visual field space is formed and the operation is convenient to be handled.
Description
Technical field
This utility model relates to medical apparatus and instruments, and particularly a kind of pneumoperitoneum stomach wall of exempting from that is used for laparoscopic surgery suspends dilator in midair.
Background technology
At present, laparoscopically surgical operation order benefit is popularized.Traditional laparoscopic surgery carries out under artificial pneumoperitoneum, and CO
2Pneumoperitoneum has certain influence to body, and it can make airway pressure increase, and compliance of the respiratory system descends, simultaneously Co
2Fine solubility is arranged, and peritoneum is absorbed into blood, makes blood PaCO
2Raise, cause hypercapnia.Pneumoperitoneum is pressed when too high, can cause subcutaneous and mediastinal emphysema, and the high carbon acid blood flow is obstructed, and cardiac function descends, the pulmonary ventilation obstacle, and the kidney filtration rate reduces and dysfunction such as cerebral vasodilators, increases operation and the risk of anaesthetizing.In order to overcome above-mentioned drawback, the pneumoperitoneum laparoscopic technique has appearred exempting from the beginning of the nineties.But these instruments are relatively more expensive, and it is higher to use an expense, is not suitable for China's actual conditions.Simultaneously, the present pneumoperitoneum laparoscopic technique of exempting from also exists surgical field of view to appear not good enough shortcoming.Can push gastrointestinal to posterior wall of abdomen at execution pneumoperitoneum seasonal epidemic pathogens abdominal pressure, flank is to the both sides projection, and the space, abdominal cavity is dome-shaped more greatly.And exempt from the pneumoperitoneum suspension apparatus when lifting abdomen, and the both sides stomach wall closes to the centre and disturbs, and the space, abdominal cavity is taper, in the middle of gastrointestinal also presses to, surgical field of view is dwindled.Secondly, exempting from the pneumoperitoneum device, to set up the pneumoperitoneum time long.Moreover puncturing hole was selected not at that time, and other apparatus will bump with the suspention pulling device and increase the operation technique difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of peritoneoscope simple in structure, easy to operate, that the surgical field of view space is bigger to exempt from pneumoperitoneum stomach wall suspention dilator.
In order to realize the purpose of this utility model, intend taking following technical scheme:
Four special- shaped support arms 2,3,4,5 flexibly connect by central shaft 1 and axis hole 9, constitute a supporting construction of taking down the exhibits freely; The abdomen end that advances of each support arm is connected with support bar 11, wherein is provided with elasticity between two following support bar 11 lower ends and draws in the net.
The handle end of above-mentioned four special- shaped support arms 2,3,4,5 is arranged in the handle 6 after drawing in, which is provided with hold-down screw 7.
Above-mentioned four support arms to advance that the abdomen end is connected with four support bars 11 be to finish by screw 12 and cooperating of screw 10.
The elasticity that is provided with between two support bar 11 lower ends of above-mentioned below is drawn in the net, its concrete structure is: two support bar 11 inboards are equipped with drag-line groove 16, be provided with drag-line fixture 15 in the groove, fixture is provided with elasticity drag-line 14, the elasticity drag-line is connected with drag hook 13 on the subtend support bar 11, draws in the net thereby constitute an elasticity.
Advantage of the present utility model is simple in structure, and flexible and convenient operation can form a good surgical field of view space, is convenient to doctor's operation, thereby improves the operation quality, reduces the operation cost.When being used for children operation, can be according to the support bar 11 of all ages and classes and art formula selection different model and profile, can provide good surgical field of view through shirtsleeve operation, overcome the existing pneumoperitoneum device of exempting from surgical field of view is appeared the shortcoming that not good enough, complicated operation, suspention pulling device hinder the operator operation.

The specific embodiment
The disclosed structure of above accompanying drawing is an embodiment of the present utility model.Among the figure, 1 for connecting the central shaft of four special-shaped support arms; 2 is the lower-left support arm; 3 is the bottom right support arm; 4 is upper left support arm; 5 is upper right support arm; 6 is fixed handle, the handle end of four support arms can be fixed together; 7 is the handle hold-down screw; 8 is to be convenient to the set holddown groove of fixed support arm handle end on the handle; 9 be on the support arm with the supporting connecting hole of central shaft 1; 10 advance the connecting hole that abdomen end and support bar join for support arm; 11 is four support bars that are connected with support arm, can be different specification size, to adapt to the child of all ages and classes; 12 is the fixed screw of support bar; 13 is the drag hook of the set elasticity drag-line in following two support bars inboard; 14 is the elasticity drag-line; 15 is elasticity drag-line fixture; 16 is elasticity drag-line groove.Four support arms 2,3,4,5 interconnect by central shaft 1 among Fig. 4, four support arms are respectively half of support arm thickness by the thickness of the overlapping part of central shaft connection, thereby make lower-left support arm 2 and bottom right support arm 3 and the in one plane corresponding motion of corresponding support bar, the corresponding motion on another plane of upper left support arm 4 with upper right support arm 5 and corresponding support bar.
More than each parts make by rustless steel basically.When this utility model uses, at first close up four support bars 11, its underpart enters the abdominal cavity through the hole on the abdominal part, close up four support arm handle ends then, and be fixed in the handle 6, this moment, following two support bars and the elasticity between them drew in the net to form the bottom surface in the peritoneoscope visual field, and top two support bars have upwards been propped up stomach wall, thereby formed the good visual-field space of a cuboid, be convenient to operation technique, improved the operation quality.
