Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of flexible electricity knife of peritoneoscope.
Background technology
Laparoscopic surgery is the operation utilizing peritoneoscope and related equipment thereof to carry out, have otch little, painful less, recover fast advantage, being widely used in the operation of various intraperitoneal, is an inexorable trend of following operation method development.Along with the Rapid Popularization of laparoscopic surgery technology and the expansion of operative indication, traditional laparoscopic surgical instruments can not be competent at the requirement of laparoscopic surgery completely.As rectal cancer surgery under peritoneoscope needs to dissociate on a large scale in narrow and small, bending pelvic cavity, and stomach wall puncture is relatively fixing, traditional peritoneoscope energy instrument is often because rectum stops or disturb between laparoscopic instrument, make it be difficult to arrive operative site smoothly, even if or reluctantly arrival be also difficult to be separated along anatomic spaces with reasonable, safe angle.
Peritoneoscope electric energy device is based on peritoneoscope coagulation rod, peritoneoscope coagulation hook; Peritoneoscope coagulation rod only possesses anastalsis, does not possess chorista effect; Peritoneoscope coagulation hook is because playing head end is that hook-type is difficult to realize accurate operation, in specific close gap and space, easily cause Accessory injury, and peritoneoscope coagulation hook does not possess bending function, meet internal organs and stop operative region, need replacement operation hole, even replacement operation hole can not arrive operative region smoothly.
Determine that the excision distance of far-end intestinal tube is one of committed step of rectal cancer surgery under peritoneoscope, according to rectum cancer treatment guide, middle or low rectal carcinoma far-end intestinal tube resection length is 2cm, middle epimere rectal cancer far-end intestinal tube resection length is 5cm, far-end intestinal tube resection length is the major reason causing recurrence of rectum cancer not, is also the Prognostic Factors affecting relapse and metastasis after rectal cancer surgery; Because laparoscopic image is the reason of dynamically amplifying according to image-forming range, according to laparoscopic image information, doctor determines that far-end intestinal tube resection length there will be deviation unavoidably, traditional laparoscopic surgery scale can the length of measurement target intestinal tube, but scale itself lacks mark action, need just can identify after the conversion of conversion apparatus, often lose metrical information accurately.
