Description
Technical field
The utility model belongs to technical field of medical instruments, and in particular to can monitor the circular staple of anastomosed tissue blood fortune in real time
Formula stapler.
Background technology
Since gastroenterostomy is carried out, healthcare givers employs different material and method to carry out gastrointestinal anastomosis.
Coincide by hand for traditional operation mode, but its technical operation difficulty is high, successful surgery whether often with healthcare givers's technical merit
Correlation, and incidence of complications is higher.
Since stapler being initiated from Hungary Fischer in 1908, existing nearly 80 years history.In nearly 30 years, circular staple
Formula stapler has progressed into our visual field, because its is easy to operate, it is quick and by the favorable comment of domestic and international doctors.
The operation principle of conventional circular nail type stapler clinical at present is identical with the stitching principle of stapler.I.e. by alimentary canal
Two broken ends of fractured bone be tightly tied in purse wire on center-pole, by tail end " identical height adjustment knob " shorten nail seat and continuously connected fastener frame it
Between distance, two ends alimentary canal is organized in the case of varus tightly pairing, then " fire " push rod, fire and plant into tissue
Enter the staple that two rows intermesh and double intersection stapling is carried out to tissue, suture is tight, prevents seepage.Meanwhile, push rod is also released
The dise knife at center is cut forward, and is cut off center annular tissue at two broken ends of fractured bone purse string sutures and is formed unobstructed previous anastomotic, completes to disappear
Change road to coincide.Staple used is in " U " type, is divided into nail leg and crown, and nail leg is highly about 5mm.Stitching tissue compression thickness
Staple height can be adjusted to 1.0mm-2.5mm.Because thin vessels can pass through from the space of " B " shape staple, therefore suturing part is not influenceed
And its blood supply of distal end.All staples are made up of Titanium or tantalum, and compared with manual suture line, tissue reaction is small；By
In staple marshalling, spacing is equal, and suture elasticity is by scale control, it is to avoid manual suture is dredged overstocked and connects bundle tension excessively
Pine is crossed, therefore ensure that highly organized healing.
As circular nail type stapler is come into operation extensively, it is following insoluble that healthcare givers have been found that it is present
Problem：Postoperative anastomotic fistula incidence is 5%~20%, and anastomotic stricture rate is 4%~10%.The reasons for the above problems
Undesirable there is direct relation with previous anastomotic Tissue Blood fortune.Presently used circular nail type stapler is in adjusting fitting Tissue approximation height
With into staple height aspect, pressure security is used interval.There is a mechanical pressure display window in stapler handle, it is desirable to coincide
Shi Hongse pointers enter green safety inframe, to ensure nail extruding height.
But, because everyone digestive tract wall thickness differs, occur substantially in segment pathology state lower digestive tract wall
Oedema is thickened, and how adjusting fitting device is into staple height, has both ensured definite stitching, and retains the space of " B " shape staple as far as possible, is protected
Demonstrate,prove the blood fortune of anastomosed tissue.User is mainly by virtue of experience the feel that extrudes during with stapler stitching to adjust.Lack true
The evidence cut.Therefore, a kind of more outstanding novel anastomat of utility model into, it is ensured that can be more objective and accurate in use
Assessment previous anastomotic blood fortune situation become study hotspot both domestic and external.
