Description
Technical field
This utility model belongs to the application of bio-medical material, relates to a kind of hollow type diaphragm that is used as hernia paster.
Background technology
In the daily life, the disappearance of tissue and organ, breakage or nonfunction are very common, and health of people and life have been consisted of serious threat.For a long time constantly exploration of people and research material and biotechnology its objective is the relevant issues that solve in the medical science, ensure human health, are prevention, diagnosis, treatment and the rehabilitation service of disease.
Hernia, namely tissue or an organ part have been left original position, enter another position by people's body space, damaged or weak part.Hernia is that a kind of multiple diseases, especially old man and child morbidity rate are higher.Because hernia can cause various diseases, and health of people and life have been consisted of serious threat.Hernia can have the danger of incarceration at any time as not treating.As occur pain, quality hard, rub and be difficult for also receiving and with stomachache, abdominal distention, the performances such as nausea and vomiting gradually occurring, the time can cause intestinal tube ischemic necrosis threat to life more for a long time.General adult suffers from afterwards voluntarily rehabilitation of hernia, must treat by external means.For hernia, different Therapeutic Method is arranged.Wherein traditional Therapeutic Method comprises: 1. hernia truss; 2. herbal treatment; 3. injection sealing; 4. surgical operation etc.For the adult, generally adopt operative treatment.Traditional operation is that breakage is directly sewed on thick line, and this method weak point is that tension force stitching, sharp ache, recovery are slow.
The treating hernia that appears as of hernia paster provides new thinking.Kugel[Kugel, Hernia mesh Patch with seal stiffener, U.S.Pat.No.6,290,708] designed the hernia paster of double-deck inert material web frame, ground floor is the hernia repair material, and the second layer is reinforcement material, the effect that hernia paster can not fold when playing operation.John Allen Pacey[John Allen Pacey, Percutaneous cannula delvery system for hernia Patch, US2002/0103494 A1] polytetrafluoroethylplastic plastic that utilizes nickel chromium triangle to strengthen, prepared hernia paster.Gregory A Spitz[Gregory A Spitz, Methods and apParatus for the rePair of hernias, US2005/0159777A1] designed a kind of hernia repair film, by hernical sac is put into preperitoneal space, after the hernical sac venting, just can open and flatly come, play the effect of hernia repair.Mainly use at present U.S. surgery company (Tyc Surgipro Plug Mate), the product of Johnson Co. and the Perifix Plug of U.S.'s Ahmedabad (Bard) company on the market, China's Mainland.This several prods all is obtained by polypropylene, and by charges and one piece of plain film composition of a taper, the modus operandi of employing is the filled type Inguinal Hernia Herniorrhaphy.
In recent years, domestic research worker also is studied aspect hernia paster.Chen Nanliang [Chen Nanliang etc., polypropylene warp-knitted hernia paster and preparation method thereof: CN1775188] has prepared hernia paster with the medical grade polypropylene monofilament by braiding, product stability and good uniformity, and quality meets or exceeds same kind of products at abroad.The people such as Shen Xinyuan [Shen Xinyuan etc., a kind of reticulated for medical hernia paster; CN101518478] prepared hernia paster with the medical grade polycaprolactone by braiding, product biological stability, good biocompatibility, polycaprolactone monofilament rigidity is relatively large, and the product mechanical property is better.Because polycaprolactone degradable does not need the taking-up of again performing the operation.The people such as Sheng Yuying [Sheng Yuying etc., hernia paster, CN2863013] have invented the polypropylene hernia paster in a kind of Permanent implantation human body.It mainly is comprised of outer layer net plug, plain film net sheet, and feature is that two four leaf petal-shaped net sheets are set in the outer layer net plug, and two four leaf petal-shaped net sheets are enclosed within and form bullet in the outer layer net plug.This sticking patch is compact, rationally; Can cut randomly according to the size of hernia, patient compliance is strong, and operating time shortens greatly, and patient's misery is little, and recovery time is short, and can prevent the hernia recurrence.The shortcoming of this product is complex structure, and preparation technology is loaded down with trivial details.
At present, hernia paster both domestic and external all is the network structure that is formed by fibrage, has comparatively soft characteristics.Its shortcoming is, after according to the wound surface size hernia paster being cut out when doctor's clinical operation, the edge part is fluffed easily, and the end of a thread is at random, brings some inconvenience to stitching, has also affected to a certain extent suture strength.In addition, netted hernia paster also exists some problems in application: repair if carry out large-area abdominal-wall defect, as deal with improperly, the cicatrix contraction in later stage can cause the distortion of net sheet, its irregular surface may stimulate and damage surrounding tissue, causes to infect the skin tunnel of dieing.
Summary of the invention
The purpose of this utility model is that the easily fluffing of back edge part, the end of a thread are at random, the cicatrix contraction can cause the problems such as hernia paster distortion for cutting out of existing of prior art hernia paster, a kind of hollow type diaphragm that is used as hernia paster is provided, be a kind of hernia paster with single thin film engraved structure, this hernia paster has preferably mechanical property and biocompatibility.When carrying out the hernia repair operation, cut out sticking patch by required size first, then to sew up, the hole on the sticking patch can be used as sewing hole.The hernia paster preparation method of this single thin film engraved structure is simple, is suitable for suitability for industrialized production.Hernia paster of the present utility model adopts thin film Carving Machining technique, obtains hollowed membrane, this engraved structure guaranteed sticking patch light and handy, thoroughly liquid, soft in, can also arbitrarily be cut out and do not produced burr the end of a thread.By the thickness degree of regulation and control thin film, can regulate thin film pliability and with the docile and obedient property of tissue.
A kind of hollow type diaphragm that is used as hernia paster of the present utility model for being with pertusate macromolecule membrane, describedly is with pertusate macromolecule membrane to be used as hernia paster; Described macromolecule membrane thickness is 0.05～1.0mm; The material of described macromolecule membrane is polyethylene (PE), polypropylene (PP), Kynoar (PVDF) or polyethylene terephthalate (PET).Above-mentioned material is medical material commonly used, and a large amount of medical practices have proved its reliability, so this utility model selects these materials to prepare hernia paster.
As preferred technical scheme:
