Bioresorbable sutures: mifananidzo, rinoporesa nguva

Mune zvimwe zviitiko, zvakadai pakuvhiya, uyewo pashure pokuberekwa waitoda nokuiswa resorbable sutures. Nokuti zvinhu izvi chinokosha rinoshandiswa. Kune akasiyana dzakawanda absorbable sutures. Izwi maronda kwakadaro kunoenderana zvinhu zvakawanda. Saka sezvo bioresorbable sutures nyunguduka?

The chikuru akasiyana stitches

Kuti tipindure mubvunzo uyu, zvakakosha kuti kujekesa ndedzipi chikuru akasiyana majoini ikoko. Kazhinji, izvozvo:

1. Internal. vazvo vakadaro seari pasi zvinokuvadza kunobva zvokuimba zvazvinoita. Nokuti unobatanidza zvinyama panguva kutsemuka kushandisa zvimwe siyana munyama. Izvi bioresorbable sutures kuporesa nokukurumidza zvakakwana. Vari Kazhinji aishanda nevakadzi pashure kusununguka kubva cervix. Muchiitiko chino, yokutindivadza usiri mutemo, sezvo chikamu ichi sikarudzi kuine nehanya.
2. Exterior. Vanogonawo uchadzingirwa uchishandisa resorbable zvinhu. Mushure wakurukura, kuti vazvo dzakadaro panguva yokumbozorora kana panguva kwetsinga pamusoro perineum, uyewo pashure kuvhiyiwa. Kana ukashandisa zvavo zvokunyama kuti kunodiwa kubvisa kwemazuva 5-7 mushure kuvhiyiwa.

It kusvetuka kuti bioresorbable sutures anogona kuporesa pashure shomanana. Zvose zvinoenderana dzakasiyana-siyana mashoko yayo sezvamunoita.

Chii absorbable sutures

Bioresorbable sutures potse nguva dzose bindepinde. Zvinonzi kashoma kushandiswa muchikuvadza kuporesa kuvhiya zvinhu izvo husingakwanisi hydrolysis. Vaiona absorbable sutures, izvo vanorasikirwa simba ravo kare panguva maawa 60. Kuparadzwa kuti filaments somugumisiro dzokuteerera:

1. Makemikari zviri varipo munyama womunhu muviri. Nemamwe mashoko, mapuroteni kuti kudzora uye kuwedzera nemakemikari.
2. Water. Izvi kwemakemikari kuita inonzi hydrolysis. In shinda iyi vanoparadzwa nemvura, izvo zviri mumuviri womunhu.

Chakaita zvokugadzirwa nembariro polyglycolide shinda "MedPGA"

Analogs kuvhiya zvinhu zvakadaro "Safil", "Polisorb", "Vicryl".

Bioresorbable sutures pashure pokuvhiyiwa kana pashure yokusununguka anogona bindepinde ne pemavara "MedPGA". zvinhu izvi zvomusejari unoitwa yakavakirwa poligidroksiatsetilovoy acid. In vakadaro Coated filaments ane resorbable polymer. Izvi zvaida kuti kuderedza uye unopfungaira capillarity, uye kuti kuderedza Kucheka kwepasi anokonzerwa pakutakura zvinhu kubudikidza tishu.

Vangani inotsidza mumwoyo shinda "MedPGA"

Bioresorbable sutures vakanga kuisa nokushandisa shinda "MedPGA" kumbotambudzika hydrolytic kudzikisirana, iyo zvachose kudzorwa. Zvinokosha kucherechedza kuti zvinhu zvakadaro zviri zvakakwana simba. Pashure pemazuva 18 pemavara ngaunyatsobata kusvika 50% simba ehupfumi.

Complete Absorção de Água kuti kuvhiya zvinhu kunoitika mazuva chete pashure 60-90. Maitiro muviri munyama kuti "MedPGA" shinda riri kunyora nezvavo.

Zvinokosha kucherechedza kuti kuvhiya zvinhu yakadaro rinoshandiswa chaizvo kuvhara zviri munyama vose, asi avo vari pasi makakatanwa, uyewo kuti refu hakuiti kuporesa nguva. Kazhinji "MedPGA" shinda yakashandiswa thoracal uye abdominal kuvhiyiwa, Gynecology, urology, epurasitiki oparesheni uye orthopedics. Zvisinei, haushandi kune huta uye zvemwoyo munyama.

Chakaita zvokugadzirwa nembariro polyglycolide shinda "MedPGA-R"

Analogs kuvhiya zvinhu zvakadaro "Safil Quick", "Vicryl Rapid".

"MedPGA-R" - a chakaita zvokugadzirwa mutsvuku akaita pahwaro poligliglaktina-910. resorbable zvinhu kwakadaro zvomusejari akazadza polymer. Izvi zvinoderedza kukweshera panguva ndima rwebhuruu nomuviri rinenge uye kunoderedza tambo uye capillarity. Kubudikidza kuvhiya zvinhu izvi zvinogona kuiswa bioresorbable sutures.

Vangani absorbable suture "MedPGA-R"

"MedPGA-R" - zvinhu zviri nyore kuti hydrolytic manyowa. tambo ava simba zvakakwana. Mushure memazuva mashanu zvabatwa 50% simba ravo zvivako. Complete Absorção de Água rinowanikwa chete 40-50 zuva. Zvinokosha kucherechedza kuti zvinyama pavakanzwa kuvhiya zvinhu "MedPGA-P" riri kunyora nezvavo. Uyezve shinda regai kukonzera Kurwara.

Pachirehwa zvokunyama kuti suture ari mucous membranes, ganda, nyoro zvinyama, uyewo ezvinhu kana uchida kutsigirwa pfupi-rokuti ronda. Zvisinei, pane kunze. pemavara vakadaro havasi kushandiswa pamusoro huta uye zvemwoyo tishu.

Chakaita zvokugadzirwa nembariro polyglycolide shinda "MedPGA-910"

Analogues zvinhu zvomusejari kwakadaro "Safil", "Polisorb", "Vicryl".

"MedPGA-910" chinhu absorbable suture akagadzira kubva poligliglaktina-910. The kuvhiya zvinhu riri kurapwa ane unhani chaiyo iyo kunoderedza "Kucheka" chaizvoizvo munguva kwemutemo zvinhu kuburikidza zvinyama, uye kuderedza capillarity uye tambo.

Misi resorption "MedPGA-910"

Saka kana takabatikana bioresorbable sutures, "MedPGA-910" seari pamwe kuvhiya zvinhu? pemavara vakadaro vane yakakwirira simba. Zvisinei, vari zvakare pasi hydrolytic kudzikisirana. Mushure memazuva 18 kuvhiya zvinhu anogona kuponesa kusvika 75% simba ehupfumi pashure pemazuva 21 - kusvikira 50% pashure pemazuva 30 - kusvikira 25%, uye pashure pemazuva 70 pane resorption yakazara filaments.

chigadzirwa iri rakashandiswa kuvhara pamusoro nyoro munyama kuti havasi pasi makakatanwa, uyewo avo kuti nokukurumidza kuporesa, mupurasitiki, thoracal uye abdominal kuvhiyiwa, Gynecology, urology uye orthopedics. Haugoni kushandisa "MedPGA-910" nokuti suturing etsinga uye zvemwoyo tishu.

Monononit "PDO"

Analogues kuvhiya zvinhu zvakadaro hazvisi zvokuti. Izvi "Biosyns" uyewo PDS II. filaments kwakadaro dzinoratidzwa vakuru chaivo chakarurama inetrtnosti, nefitilny uye noncapillary, hydrophobic, usatadzira zvinyama panguva ndima therethrough, akashinga, ndakasimba, zvakanaka dzakarukwa uye kuchengeta raiva pedyo nebundu.

Vangani kutsunga monofilament

Monofilament "PDO" kubatwa hydrolysis. Somugumisiro izvi yakabereka digidroksietoksiuksusnaya acid, zvakazara excretes. 2 weeks mushure kuvhiya suture acho anoramba kusvika 75% simba. Complete nemukuparadzwa kunoitika mukati pemavara mazuva 180-210.

Panyaya application, kuti kuvhiya zvinhu "PDO" rinoshandiswa kuti suturing uye akapfava zvinyama kwokubatana upi mhando, kusanganisira kuti muchinjikwa unobatanidza muviri zvemwoyo womwana munyama, izvo kufanira kukura. Zvisinei, pane kunze. Monofilaments hazvisi yakanakira suturing rinenge maronda yaida rubatsiro kusvika 6 vhiki, uyewo nevaya vari pasi kumusoro zvinorema. Haukwanisi kushandisa mashoko suture kana kugadzwa anodyara, chakagadzirwa mwoyo mavharuvhu, uyewo chakaita zvokugadzirwa vascular prostheses.

Saka sei vachava absorbable sutures?

Next, tarisa zvose kuti chii chinoumba bioresorbable sutures pashure pokuberekwa, kana zvakawanda, kana kuti hanya. Usakanganwa kuti zvinhu zvizhinji sei nguva ichaitika muchikuvadza kuporesa uye kunyangarika pakati filaments rakakwana. Chekutanga unofanira kuziva, kubva chii zvinhu akaita zvokuvhiyiwa zvinhu. Kazhinji, kuti shinda vanotanga kuiparadza mazuva 7-14 pashure suturing. Kuti paitwe acho, pashure maronda Provider abvise nodules. Kuti tizive nguva Absorção de Água ose shinda zvinofanira kujekeswa nachiremba:

1. Ndezvipi stitches vaiva.
2. zvinhu zvipi dzakabudiswa mutsvuku.
3. Wakanaka nemukuparadzwa nguva suture.

Pamugumo

Bioresorbable pemavara inowanzoshandiswa nokuda suturing Maronda ari anodawo, izvo riri chakadzama akaturikidzana kuti rinenge uyewo pamusoro ganda pamusoro. Somuenzaniso, mune nhengo kuisirwa.

Chete kuvhiya zvinhu inoshandiswa suturing maronda uye mitswe vakawana pakusununguka. Muchiitiko chino, yakawanda zvidzidzo kunge inoitwa. zvabuda dzavo akaratidza kuti suture yakagadzirwa polyglycolic acid, zvachose haazombotaurwi kwemwedzi mina chete, uye mashoko pahwaro polyglactin - vatatu. Saka bioresorbable sutures uchanamatira ronda micheto asati kupedza kuporeswa, uye ipapo kutanga zvishoma nezvishoma kuti kuputsa. Kana shinda kwenguva refu vanoponeswa uye kununura kusanzwa, unofanira kutsvaka rubatsiro kubva chiremba kana kupinda chiremba.
