Abstract
The invention belongs to the technical field of medical instruments and particularly belongs to a dilating device for minimally invasive operations. The dilating device comprises a dilating component, dilating support strips, a positioning and fixing device and an elastic net, wherein the front ends of the dilating support strips are connected with the elastic net respectively to dilate the elastic net to be in an umbrella shape, and the tail ends of the dilating support strips are connected with the positioning and fixing device in a shrinkage mode. At least four dilating support strips are utilized to achieve the purpose of dilating the elastic net which is made of insulation materials. When the dilating device is opened, the abdominal wall and normal tissues below the dilating device are dilated, drooping tissues of the abdominal wall above the dilating device are pushed open, the tissues do not touch an endoscope lens, and a clear view is kept. Furthermore, the dilating device is simple in structure, convenient to operate and use and suitable for being popularized and applied in related technical fields.
Description
Technical field
The invention belongs to technical field of medical instruments, specifically belong to a kind of Minimally Invasive Surgery device for spreading.
Background technology
At present, the micro-wound surgical operations such as scope are day by day universal, but after operative region adhesion release or exempt from pneumoperitoneum situation, surgical field of view poor display, causes the visual field fuzzy after endoscope lens position contact surrounding tissue, affects operation process and quality.Pneumoperitoneum menisectomy can cause the complication such as carbon dioxide accumulation, hypercapnia, subcutaneous emphysema, aeroembolism.
When general endoscopic surgery, operative site and normal structure do not separate, and normal structure is easily accidentally injured by apparatuses such as pins; normal structure is easily infected; when tumor operation, between tumor and normal structure, there is no the protector of isolation especially, easily cause tumor planting.
Summary of the invention
The object of the invention is, in order to solve deficiency of the prior art, provides a kind of Minimally Invasive Surgery device for spreading.
Device for spreading of the present invention comprises and struts device, struts support bar, device for positioning and securing and elasticated net, and the front end that wherein struts support bar is connected with elasticated net respectively, and elasticated net is strutted and is umbrella shape shape; The end that struts support bar shrinks and is connected with device for positioning and securing.The described support bar that struts is more than three, take to reach elasticated net is effectively strutted as object.
The device that struts of the present invention is connected on the culminating point of umbrella shape shape elasticated net, and corresponding with device for positioning and securing.
Elasticated net len of the present invention gets a clear view, and effectively reduces tumor cell diffusion and organization protection.
Device for spreading of the present invention can strut stomach wall and below normal structure after opening, and top is pushed the sagging tissue of stomach wall open, makes it can not encounter endoscope lens, thereby keeps getting a clear view.The below of device for spreading and both sides are needing operative site and normal structure to separate, and normal structure is difficult for being accidentally injured by apparatuses such as pins.In addition, device for spreading of the present invention is simple in structure, and handled easily is used, and is adapted at promoting the use of in correlative technology field.
Accompanying drawing explanation
Fig. 1 is the structural representation of device for spreading of the present invention.
In figure: 1, strut device; 2, strut support bar; 3, device for positioning and securing; 4, elasticated net.
The specific embodiment
For making technical scheme of the present invention and feature clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.At this, following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, device for spreading of the present invention comprises four parts, struts device 1, struts support bar 2, device for positioning and securing 3 and elasticated net 4.
The front end that wherein struts support bar 2 is connected with elasticated net 4 respectively, and elasticated net 4 is strutted and is umbrella shape shape; The end that struts support bar 2 shrinks and is connected with device for positioning and securing 3.The described support bar 2 that struts is more than three, take to reach elasticated net 4 is effectively strutted as object.
The device 1 that struts of the present invention is connected on the culminating point of umbrella shape shape elasticated net 4, and corresponding with device for positioning and securing 3.
Elasticated net 4 of the present invention is network structure, and clarity that can the len visual field, effectively reduces the diffusion of tumor cell, and tissue is effectively protected.
Device for spreading of the present invention can be realized gathering and strut function by strutting device 1, puts into operative region, by strutting device 1 through the external device for spreading of opening during gathering.Device for spreading can strut stomach wall and below normal structure after opening, and top is pushed the sagging tissue of stomach wall open, makes it can not encounter endoscope lens, thereby keeps getting a clear view.The below of device for spreading and both sides separate position and the normal structure of needs operation, and normal structure is difficult for being accidentally injured by apparatuses such as pins.
When tumor operation, between tumor and normal structure, isolate especially, reduce as far as possible tumor planting.This device for spreading under pneumoperitoneum, exempt from all can use under pneumoperitoneum.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give all embodiments exhaustive.Every still row in protection scope of the present invention of apparent variation that technical scheme of the present invention extends out or change that belong to.
