Description
Technical field
The present invention relates to a kind of minimally invasive Endo-GIA with disposable nail kit.
Background technology
In surgical operation, Minimally Invasive Surgery only needs to cut the otch of 3 to 5 very littles on patient body, will have thin
The apparatus of stock, which stretches into, to be cut and is sutured to pathological tissues in vivo, then the pathological tissues cut are taken out from elongated passageway.
Minimally Invasive Surgery has the advantages that local trauma is small, general reaction is light, post-operative recovery is fast.So it is widely used.
Minimally invasive Endo-GIA be it is a be applied to minimally invasive or open surgery in, to lung, bronchial tissue, stomach, intestines
Etc. cut off, it is cross-section and suture operating theater instruments.In use, the upper replaceable disposable nail kit of device body front end connection.One
Operation, apparatus, according to operation needs, is changed using one and uses several disposable nail kits.The front end of disposable nail kit forms one
The jaw of V-shaped, under the control of apparatus, jaw can be easy to clamping to need the pathological tissues cut off with opening and closing.Pass through
Instrumentation can promote the dynamic cutter of push blade with and nail pushing device to suture and cut pathological tissues.It is existing in the market
There is product to have the following weak point：
1st, as shown in Figure 10, the nail bin 2 and resist-nailed seat 3 of in the market existing product are planes, clamp good needs and are cut
After the tissue of suture, in cutting process, cutter can produce one by tissue when cutting tissue
Push the power of jaw front end to, in the presence of this power, tissue can produce sliding in jaw, sometimes even can be by human body
Tissue, which promotes, skids off whole jaw, so the surgical quality that cut and suture can be had a huge impact, it is impossible to thoroughly cut
Remove and suture destination organization.It can also be pulled wound the position that tissue is clamped by jaw simultaneously.
2nd, disposable nail kit is connected to device by two lugs on nail kit shell and used, and nail kit shell is answered because of shape
It is miscellaneous, it is contemplated that Cost Problems, to make working of plastics.As shown in figure 13, during the use of apparatus, tissue produces to apparatus
Reaction force be applied on the nail kit shell 17 that plastics are done, device body apply percussion force also focus on nail kit shell.
And all these external force are all concentrated on two lugs 15 and buckle 16 of nail kit shell, by the shadow in product structure space
Ring, the two places are size-constrained, it is impossible to do too big.So this concentrates the weakness that stress point is nail kit shell at two.Have because
Environmental change, ageing of plastics, the risk that factor influences and be broken such as Shooting Technique is unstable, external force is excessive.
