INTRODUCTION

Medical textiles is an emerging sector of technicaltextiles industry and its growth is increasing due toconstant improvements in healthcare as well as

innovations in the textile field.

Materials used include monofilament and

multifilament yarns, woven, knitted, and nonwoven

fabrics, and composite structures.

PROPERTIES OF MEDICAL FIBRE

Non Toxic.

Non-allergenic.

Non-carcinogenic.

Ability to be sterilized

Strength

Elasticity

DurabilityBiocompatibility

FIBRES USED

May be classified depending on whether the materials from

which they are made are Natural or synthetic,

Biodegradable or nonbiodegradable.

Natural Fibres:-cotton, silk and regenerated cellulosic fibres(viscose rayon)

Synthetic Fibres:- polyester, polyamide, PTFE, polypropylene,carbon, glass,

Biodegradable fibres:- absorbed by the body within 23 monthsafter implantation and include cotton, viscose rayon collagen,

and alginate.

Non Biodegradable fibres:- slowly absorbed within the body andtake more than 6 months to degrade are considered includepolyester , polypropylene, PTFE and carbon

EXTRACORPOREAL DEVICES

Extracorporeal devices are mechanical organs that are

used for blood purification and include the artificial

kidney , the artificial liver, and the mechanical

lung.

KEYFACTORS

Porosity : determines the rate at which humantissue will grow and encapsulate the implant.

Better encapsulation of small circular fibres withhuman tissue than larger fibres with irregularcross sections

No release of toxic substances by the fibre polymer

Should be free from surface contaminants such aslubricants and sizing agents.

Biodegradable


18/27

SUTURE

For wound closure are either monofilament or

multifilament threads.

Classified as biodegradable and Non Biodegradable

Should posses Breaking Strength and Pliability


19/27

Soft-tissue implants

The strength and flexibility characteristics of

textile materials make them particularly suitable

for soft-tissue implants. A number of surgical applications utilize these

characteristics for the replacement of tendons,

ligaments, and cartilage in both reconstructive

and corrective surgery.

CARDIOVASCULAR IMPLANTS

Vascular grafts are produced frompolyester (e.g. Dacron) or PTFE (e.g.Teflon) with either woven or knittedstructures.

Polyester vascular grafts can be heat setinto a crimped configuration that improvesthe handling characteristics.

Knitted vascular grafts have a porous

structure which allows the graft to becomeencapsulated with new tissue but theporosity can be disadvantageous sinceblood leakage can occur through theinterstices directly after implantation.

SURGICAL GOWNS AND SURGICAL DRAPES

ARE USED:

To protect patients and

hospital staff from wound

infections. To protect nurses, surgeons

and the surgical team

from liquid contaminations.

To diminish the risk to theoperating staff from blood-

borne infective agents carried

in blood or body fluids.


26/27

CONCLUSION

Textile materials are very important in all aspects of

medicine and surgery and the range and extent of

applications to which these materials are used is a

reflection of their enormous versatility.

Advances in fibre science have resulted in a new

breed of wound dressing which contribute to the

healing process.

Advanced composite materials containing

combinations of fibres and fabrics have been

developed for applications where biocompatibility and

strength are required.
