Description
Technical field
The utility model relates to Medical surgical instruments, and in particular to a kind of hand-held group of single motor electrical surgical instrument
Part, and the single motor electrical surgical instrument using the hand-held device.
Background technique
It is realized usually using stapler to the excision of tissue and the closing of the surface of a wound in surgical operation.Stapler includes that straight line is cut
Cut linear cutting anastomat etc. under stapler, tube type anastomat, hysteroscope.These staplers can be used for cutting off the disease of lung, intestines, stomach
Become tissue, while the surface of a wound is closed.In the course of surgery, the end effector of stapler is clamped and is squeezed to tissue
Then pressure is then quickly sutured the surface of a wound of generation using cutter cutting tissue using anastomosis staple.Stapler
Using operating time is shortened, the success rate of operation is improved, and post-operative recovery is fast.
Stapler used at present, which mainly passes through, manual operation and two kinds of electric operating.In surgical procedure, it must use and coincide
Device front end clamps tissue to be cut, the preparation before carrying out percussion.For the stapler of manual operation, in the mistake of percussion stapler
Cheng Zhong, doctor must complete percussion while vacantly gripping stapler by fixed handle.During entire percussion, hand is provided
Two kinds of strength of support and pressing, are easy to appear the shake of stapler caused by the shake of hand.Meanwhile percussion force is not steady enough manually
Fixed and uniformly, especially for linear cutting anastomat, when percussion, needs repeatedly pressing handle that could complete entire percussion process,
After pressing handle movement every time, need release handle carry out the pressing of handle next time again, the process of this release handle makes
It obtains cutter to halt, and pushing slice of nail also stop motion, zero is also dropped rapidly to for the thrust of anastomosis staple.Cause kissing
Dowel forms existing defects, and the cutting surface of a wound irregularity of cutter, the position above problem of especially release handle are brighter
It is aobvious.
And for electronic stapler, doctor, which need to only stablize, grips stapler, makes cutter by button and coincide
Nail movement can be realized the stable and continuous suture of the smooth motion and anastomosis staple of cutter, so that cutting effect be effectively ensured
Fruit.There is comparative study to show: relative to manual stapler is used, reducing nearly half using the hemorrhage complication of electronic stapler,
The hospitalization cost that is paid of patient reduces nearly 10% simultaneously, discharge time is advanced by one day (Impact of Powered and
Tissue-Specific Endoscopic Stapling Technology on Clinical and Economic
