Description
Technical field
This utility model relates to a kind of medical net plug, particularly a kind of net plug for peritoneoscope total extraperitoneal kposthesis.
Background technology
Certain internal organs or tissue leave the normal anatomy position in the body, enter another position by congenital or the weak spot that form the day after tomorrow, damaged or hole, namely are called hernia.Hernia betides at most abdominal part, and celiocele is in the majority with abdominal external hernia again.Abdominal external hernia is Intraabdominal internal organs or organizes together with parietal peritoneum, through stomach wall weak spot or hole, forms to body surface is outstanding.
Hernia is commonly encountered diseases and the frequently-occurring disease of general surgery, and it is the unique method of radical cure hernia that clinical practice is formally performed the operation.And the hernia Surgical Operation is more, and classification is outer two kinds: tension-free repair and tension-free hernioplasty are arranged.
From Bassini is pioneering tension-free repair is arranged since, the history in existing more than 100 years is satisfied although its general curative effect still claims so far, argument foundation and the indication thereof of relevant each art formula have arguement always, postoperative recurrence and the complication of hernia repairing still have problems.It is reported, the Postoperative recurrent rate of onset ventral groove femoral hernia is about 10%, and recurrent hernia can be up to 20%, and total complication rate is also between 7%-12%.As tension-free repair is arranged, its weak point is mainly reflected in the following aspects: 1. all be to repair with the defective adjacent tissue of patient; 2. the stitching that will not draw over to one's side by force at the tissue work of the policy region of anatomy, tension force is very large, does not meet operating principle, and 3. " stitching of associating tendon and inguinal ligament " is two kinds of stitchings between the different tissues, is difficult for producing real healing; 4. a large amount of toe-ins of leaving of prothesis have increased the chance of development of postoperative complications.
The art of tension-free hernia typing both at home and abroad formula has simple fascia to sew up prothesis, Lichtenstein(monolayer plain film repairing operation), Rutkow operation (Inguinal hernia), Gilbert operation (three-in-one without the tension force kposthesis), laparoscopic inguinal hernia repair (LiHR) etc.Tension-free hernioplasty is low with its relapse rate at present, recovery is fast, makes the hernia surgical technic that very large leap arranged, and as the main operation of radical cure hernia, progressively having replaced tradition has tension-free repair.Yet tension-free hernioplasty is promoted in China in recent years, has also occurred post-operative complication and operation defective simultaneously.Relapse rate is 1-5% behind China's tension-free hernioplasty, decreases than traditional operation, but still has gap with comparing abroad.The reason of postoperative recurrence except taking out the sticking patch because of the sticking patch deep infection, mainly is the operation blurred anatomy, sticking patch crispatura displacement, sticking patch area little, prevent that the position is improper, net plug or sticking patch fix not good.Again from various operation totally, no matter external or domestic operation is noted not for the protection of nerve fiber under cremasteric reservation, utilization and the obliquus externus abdominis m. aponeurosis (aponeuroses); Sticking patch enters human body can produce foreign body sensation, has affected to a certain extent the comfort level behind the operation in patients.
Inguinal hernia is the modal type of abdominal external hernia.Traditional therapy is that the tissues, tissue of defect is carried out suture repair, and the method Postoperative recurrent rate is high, pain is serious, recovers slow.Extensively praise highly in the whole world in recent years and adopt artificial material to carry out tension-free hernia.It is one of basic art formula of tension-free hernia that the net made from polypropylene material is filled in row net plug filled type tension-free hernioplasty, and the method is widely used in the whole world because technical operation is simple.Domestic and international existing net plug is made of the two parts that are separated from each other substantially: namely be positioned over the net plug (being made of outer plate and inner valve) of defect and the upper strata sticking patch of reinforcement inguinal canal rear wall.Because both are separated from each other, cause dark face the net plug and above plain film all must sew up fixingly, this just embodies the open defect of existing net plug structure design: 1. too much stitching may injure nervous ramification and postoperative pain occurs; 2. suture may produce to cut and lose effectively to tissue and fix, and often occurs clinically to net plug and moves to external or intraperitoneal, recurs or other severe complication and hernia occurs; 3. the inner valve of existing net plug is very soft, and is inwardly most advanced and sophisticated, can't bear pressure from the abdominal cavity and may cause the net plug outwards to rout up and recur, this also cause must sew up it fixing.These design defect have directly caused the relatively high relapse rate of present net plug prosthesis of Filling No-tension Hernia.
The tradition tension-free hernioplasty also is that this method not only wound is large by transverse fascia export-oriented abdominal cavity filling to strengthen the transverse fascia lateral surface as main, to comprise the using net plug, and easily causes art district pain behind the operation in patients, even ileac risk is arranged.
After peritoneoscope is introduced the SH operative treatment, the damage that the patient is caused greatly reduces, and the destruction that peritoneoscope total extraperitoneal kposthesis (TEP) has more been avoided peritoneum is still to guarantee a complete peritoneum seriality behind the corrective surgery, can not cause Intraabdominal adhesion because of operation.
Chinese patent CN200920081839 relates to Integral suture-free filling type tension-free herniorrhaphy mesh plug, and this utility model comprises plain film 1 and net sheet 2 beyond the Great Wall.Described net beyond the Great Wall sheet 2 edges is comprised of 8 arcs, and net beyond the Great Wall sheet 2 is connected as a single entity by joint pin 4 plain film 1 with the upper strata, and net beyond the Great Wall sheet 2 inboard radial adheres to 8 support columns 3, and support column 3 and joint pin 4 are open tubular column.On the described plain film 1 spermatic cord hole 5 is arranged.This product all adopts polypropylene for medical article to make.Because the net beyond the Great Wall plain film 1 on sheet 2 and upper strata is connected as a single entity, two aspects have been blocked damagedly from the innner and outer, have both effectively reached damaged repairing, have prevented again the movement of material; Simultaneously, radial support column 3 effectively will be netted plug and strut, make abdominal pressure be dispersed in damaged around, prevent that the net plug is outwards outstanding to reduce relapse rate.And can further strengthen inguinal canal rear wall (being the damaged outside) with the plain film 1 in spermatic cord hole 5, reach the effect of dual repairing.
But Chinese patent CN00253746 relates to a kind of perspectivity hernia for the tension-free inguinal repairing repairs netting gear, comprise by net plug and sticking patch two parts and consisting of, its net plug is nested into tapered body by two-layer petal-shaped net sheet, sticking patch is plane net sheet, but the edge of net plug and sticking patch is provided with the perspectivity tinsel.This utility model is simple in structure, easy to use, low price, can clarify a diagnosis during the postoperative check, has practical reference value.
But peritoneoscope total extraperitoneal kposthesis (TEP) can only be applied to middle-size and small-size hernia at present, and still there is the risk that remedies complete even recurrence in the inguinal hernia of hernical sac large (damaged larger〉10cm).
