Description

Soft tissue fixation devices containing Absorbable plate

Technical field

This utility model relates to the technical field of medical apparatus and instruments, and more specifically, this utility model relates to a kind of containing Absorbable plate Soft tissue fixation devices.

Background technology

Incisional hernia (incisional hernia) refers to the hernia that abdominal visceral browser or tissue highlight from abdominal incision, is the common of laparotomy ventrotomy Complication；Wherein, following abdominal midline incision incidence rate is higher, multiple is born in abdominal part stringer cutout regions, see disruption of wound, Infection, the otch of secondary healing, minority betides after not having disruption of wound medical history to occur in the Post operation long period.Its morbidity Rate is about up to 2-11%, and after wound infects, incisional hernia incidence rate may be up to about 40%.Abdominal Incisional Hernia with operative treatment is Main, the method for repairing and mending of current incisional hernia is open kposthesis and the laparoscopic incision herniorrhaphy using or not using artificial mesh. Simple tissue apposition is repaired postoperative incisional hernia relapse rate and still be may be up to 20-50%.According to the domestic principle of classification of Abdominal Incisional Hernia, clinical In with-greatly, even Huge Incisional Hernia Treated relatively conventional, and this type of incisional hernia many employings artificial mesh carries out tension-free hernia, can have Incisional hernia relapse rate is reduced to about 10% by effect ground.Peritoneoscope and the comparison of open kposthesis, have the following characteristics that

(1) laparoscopic incision herniorrhaphy follows abdominal hernia surgical principle, meets and strengthens the biological engineering mechanics principle that rear wall is repaired, Postoperative recurrent rate is up to ＜ 5%.(2) operative approach is away from former incisional hernia, reduces the chance of embedded material site infection, the most right Once the infected was had in otch.(3) abdominal wall tissue is not required to the most free destruction, preserves original intensity of stomach wall as far as possible, is more suitable for Recurrent incisional hernia.(4) still remain with between skin and artificial mesh at hernia defect and do not destroy the soft tissue of blood supply, effectively Cover compressing artificial mesh, beneficially fibrous tissue and grow in polypropylene coarse mesh, improve artificial mesh strong with the healing of abdominal wall tissue Degree.(5) in pneumoperitoneum, free hernial content is more visual and clear, and action of gravity makes hernial content naturally droop, and can avoid damage to The passive situation of intestinal tube.(6) intraperitoneal is easier to find invisible " pin hole hernia ", reduces the postoperative recurrence hernia thus caused. (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, subtracts Lack the possibility that hematoma hydrops occurs, it is not necessary to conventional drainage tube of placing, minimizing opportunities for contamination.(9) non-stomach wall through and through suture is fixed Sticking patch person, postoperative pain mild degree, persistent period are short, and patient recovers rapid.(10) laparoscopic surgery reduce infection of incisional wound, The effect of Wicresoft is reached while reducing Postoperative recurrent rate.(11) laparoscopic surgery technology requires height, needs relatively long Practise curve.Based on above feature, laparoscopic incision herniorrhaphy is the most gradually paid close attention to by people, when treating incisional hernia More and more universal.Peritoneoscope kposthesis fixes the method for sticking patch has stitching completely, complete stitching, stitching and stitching and binding agent solid Fixed etc., there is no unified standard specification at present.

In the prior art, TYCO Healthcare discloses a kind of mirror cutting seam in patent application 200810009395.6 Clutch and disposable nail kit.John Isbell Shipp discloses a kind of for fixing hernia patch in US 2007/0038220 A1 Absorbable spiral nail, described absorbable spiral nail is made up of the copolymer of lactide and Acetic acid, hydroxy-, bimol. cyclic ester.Davol, Inc., Cranston, RI discloses the method and apparatus that a kind of surgical operation is fixing in US 2007/0250064 A1.SOFRADIM PRODUCTION, Trevoux (FR) disclose a kind of I shape operation anchor in US 2003/0187465 A1.Origin Medsystems, Inc.Menlo park, Calif disclose a kind of surgery helical fastener in US5366479A.Above-mentioned fixing The application of device solves the problem such as time-consuming, inconvenient that suture is repaired.Losing blood and wound of patient can also be reduced simultaneously.Tradition Surgical fixator be staple type, the fixing deformation of staple type needs ferrum felt or other structures, and structure is complex, and valency Lattice are higher.Single-sided helix nail far-end has one to thrust a little, and near-end has a T-bar, and T-bar has been divided the diameter of spiral nail equally, carried Supply 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, 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 usual It is single use, additionally tissue may be produced frictionally damage during operation.
