Description
Technical 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 for 87.25% in all anal and intestinal diseases, and wherein common with internal hemorrhoid, account for 52.19% of all anal and intestinal diseases.Men and women all can fall ill, and women's sickness rate is 67%, and male's sickness rate is 53.9%, and any age all can fall ill, and increases the weight of gradually, therefore there be saying of " ten people's nine hemorrhoid " along with the increase at age.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 clinical experience to doctor and operating technology in operation require high, and in operation process, be easy to cause anastomosis in a period of time after anastomotic stoma oozing of blood and operation finish again to occur the phenomenons such as oozing of blood, if in time do not find and process, can cause the swelling of suture wound, 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, and the misery and the operation risk that bring to patient are high.Traditional mechanical type anastomat, the nail groove (quantity has 30 pieces and 32 pieces) of two row's annulars and interior external chiasma due to what adopt, allow anastomosis staple become B font in nail groove, this kind of mode machining accuracy to parts, the manufacturing process of the plastic strength of materials and plastic etc. is had relatively high expectations, and the fitted position of parts in assembling process, position is difficult to control, especially in batch production process, once there are quality problems in certain parts, just directly have influence on the Forming Quality of anastomosis staple, it is not firm finally in operation process, can to cause sewing up, serious causes sewing up unsuccessfully, operation risk is higher, traditional mechanical type anastomat is to utilize firing handle to drive pushing slice of nail, pushing slice of nail to promote the anastomosis staple in nail bin again, and anastomosis staple again penetrate tissue becomes B font in nail supporting base, in becoming B font, utilizes endless knife that unnecessary tissue is sewed up and excised, because the action that it is sewed up and cuts is carried out simultaneously, so power required in percussion process is just larger, therefore the skill to operator and dynamics on hand have requirement, once the dynamics of the position held of percussion operator and use grasp bad be easy to cause pulling the trigger not in place, finally cause operative failure, operation risk is high.
