Description
Technical field
The present invention relates to the technical fields of medical instrument, it is more particularly related to which titanium is followed closely and contained to a kind of titanium
The soft tissue fixation devices of nail.
Background technique
Incisional hernia (incisional hernia) refers to that abdominal visceral browser or tissue are to cut open from abdominal incision hernia outstanding
The common complication of abdomen operation;Wherein, following abdominal midline incision incidence is higher, mostly occurs in abdomen stringer cutout regions, sees
In the notch of disruption of wound, infection, healing by second intention, when minority betides no disruption of wound medical history and occurs longer after surgery
Between after.Its disease incidence is about up to 2-11%, and incisional hernia incidence may be up to 40% or so after wound infects.Incision of abdominal wall
Hernia is based on operative treatment, and the method for repairing and mending of incisional hernia is the open neoplasty and abdomen with or without the use of artificial mesh at present
Hysteroscope Incision hernia repair.The simple tissue postoperative incisional hernia recurrence rate of suture repair still may be up to 20-50%.According to incision of abdominal wall
Hernia country principle of classification, clinic in-it is big, even Huge Incisional Hernia Treated is relatively conventional, and such incisional hernia mostly uses artificial mesh
Tension-free hernia is carried out, incisional hernia recurrence rate effectively can be reduced to 10% or so.Laparoscope and open neoplasty
Compare, has the following characteristics that
(1) laparoscopic incision herniorrhaphy follows abdominal hernia surgical principle, meets the bioengineering power for reinforcing rear wall repairing
Principle is learned, Postoperative recurrent rate is up to < 5%.(2) operative approach reduces the machine of implantation material site infection far from former incisional hernia
Meeting once has the infected particularly with notch.(3) abdominal wall tissue is not required to free destruction extensively, and preservation stomach wall is original strong as far as possible
Degree, is more suitable for recurrent incisional hernia.(4) it is still remained between hernia defect point skin and artificial mesh and does not destroy the soft of blood supply
Tissue, effectively covering compressing artificial mesh, grow into polypropylene coarse mesh conducive to fibr tissue, improve artificial mesh and stomach wall group
The Healing strength knitted.(5) hernial content that dissociates in pneumoperitoneum is more intuitive clear, and gravity naturally droops hernial content,
It can avoid the passive situation of damage intestinal tube.(6) intraperitoneal to be easier to find invisible " pin hole hernia ", art caused by reducing thus
Recurrent hernia afterwards.(7) the fixed sticking patch of abdominal cavity in seaming nail multiple spot, even tension dispersion are lowered.(8) sticking patch implanted region is cut without skin
Mouthful, reduce the possibility that hemotoncus hydrops occurs, it is not necessary to it is conventional to place drainage tube, reduce opportunities for contamination.(9) non-stomach wall through and through suture
Fixed sticking patch person, postoperative pain mild degree, duration are short, and patient restores rapid.(10) laparoscopic surgery is reducing notch sense
Achieve the effect that while dye, reduction Postoperative recurrent rate minimally invasive.(11) laparoscopic surgery technical requirements are high, need relatively long
Learning curve.Based on the above feature, laparoscopic incision herniorrhaphy is gradually concerned by people in recent years, in treatment incisional hernia
When it is more more and more universal.The method of the fixed sticking patch of laparoscope neoplasty has complete suture, complete stitching, suture and stitching and adhesive
It is fixed etc., it there is no unified standard to standardize at present.
