Energy type hemorrhoid cutting stapling apparatusTechnical field
The present invention relates to a kind of energy type hemorrhoid cutting stapling apparatus, belong to medical instruments field.
Background technology
At present, anal and bowel pile is commonly called as hemorrhoid, is the distinctive commonly encountered diseases of the mankind, frequently-occurring disease.Show according to relevant reconnaissance information, the sickness rate of anorectal disease is 59.1%, and hemorrhoid account in all anal and intestinal diseases 87.25%, and wherein common with internal hemorrhoid, account for 52.19% of all anal and intestinal diseases.Men and women all can fall ill, and the sickness rate of women is 67%, and the sickness rate of male is 53.9%, and any age all can fall ill, and increases the weight of gradually along with the increase at age, therefore has saying of " ten people nine hemorrhoid ".General operative treatment comprises the traditional operations such as ligation method, Barron ligation, hemorrhoid resection and anastomosis method.Comprise now the hemorrhoid resection and anastomosis device of well-known medical producer all production traditional mechanical formulas such as U.S. outer, Johnson & Johnson, Kang Di, Frank be graceful both at home and abroad, this kind of apparatus requires high to the clinical experience of doctor and operating technology in operation, and be easy in operation process cause anastomotic stoma oozing of blood again to occur the phenomenons such as oozing of blood with anastomosis in a period of time after terminating of performing the operation, if there is no Timeliness coverage and process, the swelling of suture wound can be caused, fester, consequence can be very serious, and success rate of operation is low.And the operation after above method, operating time is long, and the healing cycle of wound is long, the misery brought to patient and operation risk high.Traditional mechanical type anastomat, be two row's annulars and the nail groove of interior external chiasma (quantity has 30 pieces and 32 pieces) due to what adopt, anastomosis staple is allowed to become B font in nail groove, this kind of mode is to the machining accuracy of parts, the manufacturing process of the plastic strength of materials and plastic etc. require higher, and parts fitted position in an assembling process, position is difficult to control, special in batch production process, once there are quality problems in certain parts, just directly have influence on the Forming Quality of anastomosis staple, stitching finally can be caused in operation process not firm, serious causes sewing up unsuccessfully, operation risk is higher, traditional mechanical type anastomat is the anastomosis staple utilizing firing handle to drive pushing slice of nail, pushing slice of nail to promote in nail bin again, and anastomosis staple again penetrate tissue becomes B font in nail supporting base, while one-tenth B font, utilize endless knife to be carried out sewing up and excising by unnecessary tissue, the action sewed up due to it and cut is carried out simultaneously, so power required in percussion process is just larger, therefore requirement is had to the skill of operator and dynamics on hand, once the position held of percussion operator and dynamics grasp bad being easy to and cause percussion not in place, finally cause operative failure, operation risk is high.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, a kind of energy type hemorrhoid are provided to cut stapling apparatus, it needs to select more than one piece or two pieces electrode block first to carry out solidifying closing to tissue according to hemorrhoid condition of illness in operation, close rear remaining tissue and carry out excision to solidifying and process again, thus improve the healing rate of wound, shorten the recovery period of patient and avoid sewing up mouth place oozing of blood and hemorrhage phenomenon, reduce the production precision of parts simultaneously, significantly reduce the dynamics of percussion.
