Description
Technical field
The present invention relates to a kind of movable head absorbable biological nail band pin anorectal, gastrointestinal anastomosis device, belong to medical instruments field.
Background technology
At present, for anorectal in surgical operation, gastrointestinal uses Anastomat hemorrhoidal circumcision all to adopt titanium nail and stainless steel lag screws as stapler to anorectal, coincide after gastrointestinal excision, after coincideing, namely titanium nail is stayed in human body, by the meeting Automatic-falling had after growth anastomotic healing, mostly stay in the body, although titanium nail material is better to human compatibility, meet national requirements human implantable, but stay for a long time in human body as a foreign body, no matter from fact saying or all can producing certain influence psychologically, also the interrelated data that titanium alloy has no effect to human body is had no in existing document, so there is foreign body always good not as there is no foreign body in human body, the anastomat of foreign body is not stayed after whether designing a kind of surgical stapling healing of novelty, match result can meet applicable clinical completely, this problem is badly in need of solving, in addition, when resist-nailed seat of anastomat being put into intestinal pipe, it is vertically kept flat and enters intestinal pipe intestinal tube can be made to expand, resistance increases.Put into difficulty, because the endoporus of identical metagaster diminishes during taking-up, intestinal hole dilatancy when taking out by force, can make the nail portion sewed up pull to cause hemorrhage.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, a kind of movable head absorbable biological is provided to follow closely band pin anorectal, gastrointestinal anastomosis device, its nail supporting base assembly can disassemble cleaning easily, and can swing, conveniently enter and take out, its anastomosis staple is degraded in human body, anastomosis staple can be avoided to be detained in human body and the postoperative complication phenomenon occurred.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of movable head absorbable biological nail band pin anorectal, gastrointestinal anastomosis device, comprise anastomosis cut component, firing handle assembly, nail supporting base assembly and the screw component through anastomosis cut component, nail supporting base assembly has movable axis, nail supporting base, jump ring pipe and knife washer, knife washer is arranged on nail supporting base, movable axis is hinged on jump ring pipe, anastomosis cut component comprises endless knife, nail storehouse sleeve, pushing slice of nail and the nail bin being fixed on nail storehouse sleeve front end, jump ring pipe is inserted into one end of screw component, the other end of screw component is provided with adjusting nut assembly, the afterbody of anastomosis cut component is equipped with fixed handle assembly, the head end of pushing slice of nail is fixed with some tissue penetration pins, there is in nail bin some anastomosis staples be made up of Biodegradable material, anastomosis staple is sleeved on tissue penetration pin, and the syringe needle of tissue penetration pin exposes anastomosis staple, described nail supporting base is being provided with the pressure cap that can fix anastomosis staple with the corresponding position of multiple anastomosis staple, pressure cap is also made up of Biodegradable material, the swing limiting mechanism making nail supporting base assembly have multiple fixing pendulum angle is provided with between described movable axis and jump ring pipe.
Further, described swing limiting mechanism comprises control spring and swings positioning bead, control spring and swing positioning bead are all contained in jump ring pipe, one end of control spring is against on jump ring pipe, the other end of control spring props up swing positioning bead, and the tail end of described movable axis has swing positioning bead when stopper slot that is multiple and swing positioning bead scarf swings with convenient nail supporting base assembly and is inlaid in stopper slot under the effect of control spring.
Further, the inwall front portion of described pressure cap is the contraction-like structure to nail supporting base direction, and this position has open slot, and described anastomosis staple has nail head and pressure cap auxiliary section, and the diameter of pressure cap auxiliary section is less than nail head.
Further, described Biodegradable material is polylactic acid or pla-pcl or polyglycolic acid, or the copolymer of at least two kinds in polylactic acid, pla-pcl and polyglycolic acid.
Further, described Biodegradable material is collagen protein or chitosan or hyaluronic acid, or is alginate and derivant thereof.
After have employed technique scheme, Biodegradable material is used to make anastomosis staple, the anastomosis staple of this kind of material there occurs revolutionary change, former anastomat utilizes stapler principle, material is titanium alloy wire and stainless steel silk, existing anastomosis staple material is a kind of a kind of macromolecular material absorbed by the body, it not peg, so a kind of method that its identical principle takes bayonet type and compression type two unification reaches identical object, the design of anastomosis staple adopts bayonet type ejector pin, its ejector pin principle and former anastomat constant, anastomosis staple due to this kind of material is a kind of high molecule plastic, its nail head cannot reach sharp as metal staples, so the tissues such as intestinal wall cannot be penetrated well, for this situation, devise and secure sharp tissue penetration pin on pushing slice of nail, by nail bin and anastomosis staple, when making it pull the trigger stitching, first sharp tissue penetration pin pierces through the tissues such as intestinal wall, its anastomosis staple follows penetrate tissue, the pressure cap in nail supporting base is penetrated while penetrate tissue.Because the inwall front portion of pressure cap devises open slot, opening is utilized to strut when anastomosis staple interference is passed, swelling principle, anastomosis staple passes, because there is a shoulder nail head and pressure cap auxiliary section, when anastomosis staple penetrates into pressure cap auxiliary section, pressure cap bounces back, sew up and stop, only anastomosis staple shoulder place is stuck on pressure cap and cannot retreats, thus be clamped suture tissue, reach sewing effect, endless knife in the middle of sewing up while cuts endoporus and arrives maximum through-hole effect, in addition, can easily put into and take out after manually swinging nail supporting base assembly angle, pendulum angle is located by the stopper slot on movable axis, swing positioning bead to head in stopper slot under the effect of control spring and reach control position and position, when swing positioning bead is in the stopper slot of centre, nail supporting base assembly becomes plumbness, percussion can be carried out coincide, when both sides stopper slot, nail supporting base assembly tilts at angle, convenient insertion and taking-up.
The present invention has following beneficial effect:
1, it uses operation principle identical with former anastomat, without the need to changing its use habit;
2, penetrate tissue devises sharp tissue penetration pin, utilizes tissue penetration pin to penetrate rear suture needle along tissue penetration pin penetrate tissue, solves plastics without the not strong defect of sharpness, penetrate tissue;
3, while penetrate tissue, its endless knife carries out interior cut hole and penetrates pressure cap carrying out the synthesis of stitching one gas;
4, nail supporting base assembly of the present invention can disassemble cleaning easily, and can swing, and conveniently enters when performing the operation and takes out.
