Abstract
A totally-laparoscopic circular stapler nail anvil embedding device is characterized by comprising a metal bar (1) and a nail anvil (4), wherein one end of the metal bar (1) is a connecting end (2); the other end of the metal bar (1) is a guiding end (3); the head end of the nail anvil (4) is shaped like a spherical umbrella; the other end of the nail anvil (4) is a center rod (5); the tail end of the center rod (5) is connected with a puncture head (6); and the connecting end (2) of the metal bar (1) is connected with the puncture head (6). After the adoption of a nail anvil embedding method provided by the invention, a circular stapler nail anvil can directly penetrate through the side wall of an esophagus without the need of purse string suture, so that the cutting position of the esophagus is heightened, which can guarantee the resection margin of cancer at the joint of the esophagus and a stomach and improve the effect of radical treatment of cancer. Meanwhile the method avoids the phenomenon that the wall of the esophagus crimps due to purse string tightening, the nail anvil is closer to a nail bin, the nailing is tighter, the probability of incomplete anastomosis is reduced, and thus the probability of laparoscopic esophagus-jejunum anastomotic leakage complications can be reduced remarkably.
Description
Technical field
The invention belongs to medical instruments field, relate to tube type anastomat nail anvil head embedded device and manufacture method under a kind of full peritoneoscope.
Background technology
Surgery operation on digestive tract usually needs two hollow organs to coincide, as esophagus and stomach are coincide, and esophagus intestinal anastomosis.Traditional anastomosis coincide with suture, and it is reliable for effect, but complex operation, and technical requirement is high.A series of digestive tract stapler is designed for addressing this problem.Its design principle comes from stapler, and the kiss (seam) of apparatus closes position and is equipped with as stapler
the staple of shape, thrust in
staple makes it pass gastrointestinal tissue, then bend to " B " shape, gastrointestinal tissue is stitched together.Within 1954, former Soviet Union's Moscow experimental surgery apparatus institute starts design and manufacture anastomat.Nineteen sixty has made PKS circular stapler and has been applied to clinical.The Ravitch of the U.S. in 1972 has developed the anastomat of the former Soviet Union, has manufactured and designed serial anastomat product.Through constantly improvement and innovation, digestive tract stapler widely uses clinically.Wherein tube type anastomat major axis apery body rachiocamposis angle design, meets the natural torsion of human anatomy, is suitable for appearing coincideing of more difficult position, as esophagus intestinal anastomosis, low rectal coincide.At present, domestic hospitals uses more import anastomat to be surgery company of the U.S. (Fig. 1) and the product treasuring company of Kanggong department (Fig. 2) two.
Surgery company of the Tu1Shi U.S. produces Digective canal tubular anastomat, and in Fig. 1,1 is nail supporting base button; 2 pinch groove for hands; 3 is orange ligation district; 4 is centimeter scale; 5 is bumper bar; 6 is indicating window; 7 is pocket knot groove; Bar centered by 8; 9 is loop bar; 10 is trigger shaft; 11 is adjusting screw(rod); 12 is tack nail supporting base; 13 is through wires hole; Puncturing head centered by 14.
Kanggong department product Digective canal tubular anastomat is treasured by the Tu2Shi U.S..In Fig. 2,1 is nail supporting base; 2 is pocket knot groove; 3 is springlock; Bar centered by 4; 5 is indicating window; 6 is adjusting knob; 7 is orange ligation district; 8 wear tartar for device; 9 is nail storehouse sleeve; 10 is bumper bar; 11 is trigger shaft; 12 is auxiliary perforator; 13 is baffle; 14 is protective cover.
Under full peritoneoscope, use tube type anastomat to carry out in the process of esophagus intestinal anastomosis, anastomat nail anvil head inserts the committed step that esophagus is operation.Traditional method for posting opens esophagus tube chamber, and edgewise carries out purse string suture, utilizes vascular forceps to clamp nail anvil head center-pole, nail anvil head is inserted digestive tract intracavity (center-pole is outside), draws purse string suture line in, fixed central rod.The method is processing ease in conventional therapy, but in laparoscopic surgery operating difficulties, and insert the easy slippage of nail anvil head in process, bring greater risk and uncertainty to the identical of esophagus jejunum.
In order to solve the technical barrier of inserting nail anvil head, the present invention designs a kind of metallic rod, utilizes this metallic rod, under peritoneoscope, nail anvil head is inserted esophagus.The method of tube type anastomat nail anvil head is inserted under the invention provides a kind of full peritoneoscope newly.
Summary of the invention
The object of this invention is to provide tube type anastomat nail anvil head embedded device and manufacture method under a kind of full peritoneoscope.
Technical scheme of the present invention is as follows:
Tube type anastomat nail anvil head embedded device under a kind of full peritoneoscope, comprise metallic rod 1 and nail anvil head 4, described metallic rod 1 one end is link 2, the other end is leading end 3, the head end of nail anvil head 4 is ball umbrella shape, bar 5 centered by the other end, center-pole 5 end connects puncturing head 6, and the link 2 of metallic rod 1 is connected with puncturing head 6.
Described puncturing head 6 is taper, and it offers through wires hole.
The link 2 of described metallic rod 1 inserts in the through wires hole of puncturing head 6, and bending is fixing.
The leading end 3 of described metallic rod 1 is ring-type, is bent to form by metallic rod 1.
A manufacture method for tube type anastomat nail anvil head embedded device under full peritoneoscope, comprises the following steps:
The first step: make metallic rod 1, long 4-8cm, diameter 0.8-1.2mm, material is ferrum, its one end is bent the leading end 3 making ring-type;
Second step: make nail anvil head 4, the head end of nail anvil head 4 is ball umbrella shape, bar 5 centered by the other end, center-pole 5 end connects the puncturing head 6 of taper, and puncturing head 6 offers through wires hole;
3rd step: the other end of metallic rod 1 penetrates the through wires hole of puncturing head 6 and folds, and forms the link 2 of metallic rod 1, thus is connected with metallic rod 1 by the center-pole 5 of nail anvil head 4.
Beneficial effect of the present invention
After adopting nail anvil head method for posting of the present invention, tube type anastomat nail anvil head need not can directly pass from esophagus sidewall by purse string suture, and the position that esophagus is cut off is improved, and is conducive to the incisxal edge ensureing esophagus and stomach joint portion cancer, improves the radical cure effect of tumor; Simultaneously the method esophageal wall can not tighten up generation shrinkage because of pocket, and the spacing of nail supporting base and nail bin is nearer, stitching is tighter, and the infull probability that occurs coincideing reduces, and thus significantly can reduce esophagus intestinal anastomosis mouth under peritoneoscope and leak the probability that complication occurs; And operate fairly simple, can operating time be reduced.The inventive method is that under full peritoneoscope, inserting of tube type anastomat nail anvil head provides new method, can be used for the experimentation of esophagus intestinal anastomosis under peritoneoscope.
