Description
Technical field
The invention belongs to medical instruments field, relate 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.
Summary of the invention
The object of the invention is the above-mentioned deficiency for prior art, a kind of flexible electricity knife of peritoneoscope is provided.
A kind of flexible electricity knife of peritoneoscope, comprises electric knife head, front bar, mobile jib, mobile jib handle, the interior bar running through front bar, mobile jib and mobile jib handle longitudinal central axis line and screw putter; Interior bar is two-part, and leading portion is positioned at front bar, and rear end is positioned at mobile jib and mobile jib handle, and the head of interior bar leading portion connects electric knife head, and the afterbody of interior bar back segment connects coagulation joint, and in two sections, bar is connected by interior bar joint; Mobile jib is connected with front bar by the mobile jib joint of mobile jib both sides; In in mobile jib, outside bar, cover has screw putter, mobile jib handle is provided with and adjusts curved knob, adjusts the tooth on curved knob to dash forward and threaded engagement on screw putter, rotates and adjusts curved knob that screw putter can be driven to stretch; Screw putter is connected with front bar by push rod joint, the flexible promotion front bar of screw putter with mobile jib joint for the relative mobile jib in axle center bends; Adjust inside curved knob with teeth groove, adjust curved knob front mobile jib handle and mobile jib junction to be provided with fixed knob, fixed knob is engaged with the teeth groove adjusted inside curved knob, controls to adjust curved knob to rotate, thus control screw putter stretches, and reaches the object of fixing mobile jib joint flexion angle.Electric knife head root is provided with pottery protection head, and pottery protection head is connected with front club head.Pottery protection head holds electric knife head, can withstand high temperatures, and plays the effect of insulation.Mobile jib and front bar plate insulating blanket outward, play the effect of insulation.Mobile jib and front bar junction cover had insulate and protective tissue from the soft rubber sleeve of card pressure effect.
The joint of coagulation described in the present invention adopts general peritoneoscope monopolar electrocoagulation joint, directly can connect peritoneoscope coagulation hook connecting line.
In the present invention, the length ratio of front bar and mobile jib is 1:1 ~ 7.Usually before, pole length is 5cm, and mobile jib length is 30cm.
As another kind of optimal way of the present invention, front rod outer surface is provided with some annular Warning Marks, indicates electric knife head tip to the distance of every bar annular Warning Mark respectively.
As most preferred mode of the present invention, front rod outer surface is provided with the first annular Warning Mark and the second annular Warning Mark, indicate the distance of 5cm between the annular Warning Mark of 2cm and electric knife head tip to the second between the annular Warning Mark in electric knife head tip to the first respectively, while determining the excision distance of 2cm or 5cm, incisxal edge line can be identified with electric knife head 12.This mode is especially useful in the incisxal edge determining tumor far-end intestinal tube in peritoneoscope rectal cancer surgery.
The application of flexible electricity knife of peritoneoscope of the present invention in laparoscopic surgery; Application preferably in peritoneoscope rectal cancer surgery.
Flexible electricity knife of peritoneoscope of the present invention is preparing the application in laparoscopic surgery armarium; Preferably preparing the application in peritoneoscope rectal cancer surgery armarium.
