Description
Technical field
The present invention relates to the technical field of medical apparatus and instruments, more particularly, the present invention relates to a kind of soft tissue fixation devices containing titanium nail.
Background technology
Incisional hernia (incisionalhernia) refers to the hernia that abdominal visceral browser or tissue are given prominence to from abdominal incision, is the common complication of laparotomy ventrotomy; Wherein, following abdominal midline incision incidence rate is higher, is multiplely born in abdominal part stringer cutout regions, sees the otch of disruption of wound, infection, secondary healing, and minority betides does not have disruption of wound medical history and after appearing at the Post operation long period.Its sickness rate Yue Keda 2-11%, and after wound generation infection, incisional hernia incidence rate can up to about 40%.Abdominal Incisional Hernia is based on operative treatment, and the method for repairing and mending of current incisional hernia is the open kposthesis and the laparoscopic incision herniorrhaphy that use or do not use artificial mesh.Simple tissue apposition repairs postoperative incisional hernia relapse rate still can up to 20-50%.According to the domestic principle of classification of Abdominal Incisional Hernia, clinical with in-Huge Incisional Hernia Treated is comparatively common greatly, even, and this type of incisional hernia many employings artificial mesh carries out tension-free hernia, effectively incisional hernia relapse rate can be reduced to about 10%.Peritoneoscope compares with open kposthesis, has following characteristics:
(1) laparoscopic incision herniorrhaphy follows abdominal hernia surgical principle, and meet the biological engineering mechanics principle strengthened rear wall and repair, Postoperative recurrent rate can reach < 5%.(2) operative approach is away from former incisional hernia, reduces the chance of embedded material site infection, especially once has the infected for otch.(3) abdominal wall tissue does not need extensively free destruction, preserves original intensity of stomach wall as far as possible, is more suitable for recurrent incisional hernia.(4) still remain with the soft tissue not destroying blood supply between hernia defect place skin and artificial mesh, effectively cover compressing artificial mesh, be beneficial to fibrous tissue and grow in polypropylene coarse mesh, improve the Healing strength of artificial mesh and abdominal wall tissue.(5) in pneumoperitoneum, free hernial content is more visual and clear, and action of gravity makes hernial content naturally droop, and can avoid the passive situation damaging intestinal tube.(6) intraperitoneal is easier to find invisible " pin hole hernia ", reduces the postoperative recurrence hernia caused thus.(7) abdominal cavity in seaming nail multiple spot fixes sticking patch, and even tension dispersion is lowered.(8) sticking patch implanted region is without skin incision, decreases the possibility that hematoma hydrops occurs, need not conventional placing drainage, decreasing pollution chance.(9) the non-stomach wall through and through suture person that fixes sticking patch, postoperative pain mild degree, persistent period are short, and patient recovers rapid.(10) laparoscopic surgery reaches the effect of Wicresoft while reducing infection of incisional wound, reducing Postoperative recurrent rate.(11) laparoscopic surgery technical requirement is high, needs the learning curve relatively grown.Based on above feature, laparoscopic incision herniorrhaphy receives the concern of people in recent years gradually, more and more universal when treating incisional hernia.The method that peritoneoscope kposthesis fixes sticking patch has stitching completely, stitching completely, stitching and stitching and binding agent to fix, and there is no unified standard specification at present.
In the prior art, TYCO Healthcare discloses a kind of mirror stapler and disposable nail kit in patent application 200810009395.6.JohnIsbellShipp discloses a kind of Absorbable rod spiral nail for fixing hernia patch in US2007/0038220A1, and described Absorbable rod spiral nail is made up of the copolymer of lactide and Acetic acid, hydroxy-, bimol. cyclic ester.Davol, Inc., Cranston, RI disclose the fixing method and apparatus of a kind of surgical operation in US2007/0250064A1.SOFRADIMPRODUCTION, Trevoux (FR) disclose a kind of I shape operation anchor in US2003/0187465A1.OriginMedsystems, Inc.Menlopark, Calif disclose a kind of surgery helical fastener in US5366479A.The problem such as consuming time, inconvenient that the application of above-mentioned holder solves that suture repairs.Also can reduce losing blood and wound of patient simultaneously.Traditional surgical fixator is staple type, and the distortion that staple type is fixed needs ferrum felt or other structures, and structure is comparatively complicated, and price is higher.Single-sided helix nail far-end has one to thrust a little, and near-end has a T-shaped bar, and T-shaped bar has divided the diameter of spiral nail equally, provides a stress surface.The another kind of form of spiral nail is two-sided spiral, and far-end has two to thrust a little, and near-end has a connection strap, and connection strap is connected to two spiral coils, has divided the diameter of two spiral coils equally simultaneously.In the prior art, fixer structure is single use normally, may produce frictionally damage in addition during operation to tissue.
