Abstract
The invention discloses an endoscope retractor of minimally invasive surgery. The endoscope retractor embedded into an abdominal cavity through a minimally invasive incision is unfolded to form a support frame vertically uplifting the abdominal wall to form a surgical space. The endoscope retractor comprises a retractor body, a lifting joint and a bed rail clamp and is characterized in that an outer-frame arc portion, an inner-frame arc portion, an outer-frame neck portion and an inner-frame neck portion are folded to extend into the surgical incision and are slowly placed into the abdominal cavity, a handle of a left blade and a handle of a right blade are withdrawn inwardly, a blade jackscrew of the right blade is screwed, and the retractor is unfolded in the abdominal cavity; after the retractor is connectively fixed through the lifting joint and a lifting rod of the bed rail clamp, a rocking handle of the lifting joint is rocked, and the abdominal wall is vertically uplifted to form the surgical space. Artificial CO2 pneumoperitoneum can be largely replaced by the endoscope retractor of the minimally invasive surgery to perform laparoscopic surgery, damages, and risks and side effects caused by the artificial CO2 pneumoperitoneum can be avoided; the endoscope retractor is simple and convenient to operate, sufficient in surgical field exposure and shortened in surgical time.
Description
Affiliated technical field
The present invention relates in the laparoscopic surgery of surgery, substitute artificial CO
2pneumoperitoneum exposes the chamber mirror Minimally Invasive Surgery retractor of surgical field of view.
Background technology
Current clinical laparoscopic surgery relies on artificial CO
2pneumoperitoneum separates peritoneal wall and internal organs, exposes surgical field of view.Studies confirm that the CO that is greater than 10mmHg
2pneumoperitoneum can cause pulmonary ventilation function decline, hypercapnia, cardiac afterload to increase, heart does work decline, myocardial oxygen consumption increase etc., respiratory circulatory system is produced to harmful effect, especially the patient to original cardiopulmonary disease, serious hypercapnia and acidosis be may cause, original breathing, circulatory function obstacle increased the weight of; To local internal organs as: liver, kidney, brain, gastrointestinal etc. exert an influence, and make that the rising of multiple liver enzyme, bilirubin and clotting time change, renal perfusion amount reduces, intracranial pressure raises, the anti-stream of gastric juice etc.In addition, shoulder pain, nausea and vomiting, subcutaneous emphysema, preperitoneal emphysema, the complication such as pneumoretroperitoneum and omentum majus inflation also happen occasionally clinical.Artificial CO is also found in research both at home and abroad
2pneumoperitoneum also causes postoperative neoplasm metastasis, plantation, recurrence most probably.
Summary of the invention
The invention provides one and can put into abdominal cavity by Minimally Invasive Surgery otch, then launch at intraperitoneal, directly promote stretching stomach wall and form operative space, expose the chamber mirror Minimally Invasive Surgery retractor of surgical field of view.
The technical solution adopted for the present invention to solve the technical problems is: chamber mirror Minimally Invasive Surgery retractor is mainly made up of retractor, lifting joint and bed rail folder.Retractor is direct support, stretching stomach wall part, and lifting joint presss from both sides and makes it according to elevating lever vertical-lift part for retractor is connected and fixed on to a rail, and bed rail folder is the part that is connected to a fixed by clamp and operation table.Retractor is made up of symmetrical lobus sinister and lobus dexter, blade jackscrew, tightening knob and linking arm, and lobus sinister and lobus dexter are mainly made up of the soft head of handle, torsion spring, locking tooth, locking retainer, outrigger cervical region, gear 1, gear 2, outrigger arc portion, outrigger soft spring, the soft head of outrigger, internal frame cervical region, internal frame engaging tooth, internal frame arc portion, internal frame soft spring and internal frame respectively.Lifting joint is mainly made up of cam pressure handle, shoulder joint, shake joint and rocking handle, and bed rail folder is mainly made up of elevating lever and clamp.Chamber mirror Minimally Invasive Surgery retractor is connected in the shoulder joint in lifting joint by the linking arm of retractor, the shake joint in lifting joint is connected in an elevating lever for rail folder, and the clamp of bed rail folder is connected in operation table.
Principle of the present invention is from the lobus sinister of closure state retractor and the soft head end of lobus dexter outrigger, the outrigger arc portion closing up, internal frame arc portion, outrigger cervical region and internal frame cervical region are prolonged to operative incision in the lump and slowly insert intraperitoneal, the handle of interior receipts lobus sinister and lobus dexter, gear 1 driven gear 2 rotates, thereby make the outward turning of outrigger arc portion, the abduction of lobus sinister and lobus dexter, two outrigger arc portions of retractor launch at intraperitoneal, then screw the blade jackscrew of lobus dexter, lobus sinister and lobus dexter are separated, form the retractor of open configuration at intraperitoneal; The clamp of bed rail folder is connected and operation table, the shake joint in lifting joint is connected in to an elevating lever for rail folder, the linking arm of retractor is connected in to the shoulder joint in lifting joint, compress the linking arm of the cam pressure handle self-retaining retractor in lifting joint, screw the tightening knob of retractor, the rocking handle in shake lifting joint, two internal frame arc portions of retractor and two outrigger arc portions are stomach wall dome sample struts and promote vertically upward and form operative space.
The oppositely rocking handle in shake lifting joint, retractor declines, press the locking tooth of retractor lobus sinister and lobus dexter, locking tooth and the occlusal surface of locking retainer are separated, by the handle abduction of lobus sinister and lobus dexter, make the outrigger arc portion inward turning of lobus sinister and lobus dexter, interior receipts, unscrew the blade jackscrew of lobus dexter, make lobus sinister and lobus dexter tight, bed rail folder is returned to closure state, unclamp the cam pressure handle in lifting joint, bed rail folder can easily take out from operative incision.
The soft head of the soft head of the lobus sinister of retractor and the outrigger of lobus dexter [18] and internal frame [16] uses more soft material to make, and adopt the structure of embedding outrigger soft spring [17] and internal frame soft spring [15], the power producing can promote stomach wall with retractor time is out of shape naturally, can avoid again stomach wall to cause damage; The folding degree of outrigger arc portion and internal frame arc portion can be adjusted as required, can avoid easily the placement location of the apparatuses such as peritoneoscope in operation, does not affect patient's operation; Internal frame cervical region plays the effect of tractive expansion otch in the incision of stomach wall, be beneficial to operation technique.
The present invention compared with prior art, the alternative artificial CO that chamber mirror Minimally Invasive Surgery retractor can be greatly
2pneumoperitoneum carries out laparoscopic surgery, and installs and simple, and operating field exposes fully, uses easy to operately, greatly shortens operating time.
The invention has the beneficial effects as follows: 1. avoid by artificial CO
2damage, danger and side effect that pneumoperitoneum causes; 2. installation and simple to operate, quick, removes the work CO that makes children from
2the time of pneumoperitoneum, reduce time cost, save human resources; 3. save and buy CO
2the expense of pneumoperitoneum apparatus.
