Transcript of Sutures ( stitches )
Surgical suture is a medical
device used to hold body tissues together after an injury or
surgery. Application generally involves using a needle with
an attached length of thread. A number of different
shapes, sizes, and thread materials.
1. Easy to handle2. Have minimally reaction in tissue3. Inhibits bacterial growth4. Holds securely when knotted5. Resist shrinking in tissue6. Is no capillary, no allergenic, no carcinogenic 7. Absorbs with minimal reaction after tissue has healed
NOTE: Such an ideal suture does not exist.
To be continued…
Surgical catgut are of 2 types:1. Plain surgical gut / type A2. Treated surgical gut / type C
• Plain surgical or
untreated surgical
gut or type A
• Treated surgical gut or type C
• Unable to retain
tensile strength just for
7days
• Able to retain its tensile
strength for about 10-14days
• Multifilament • Multifilament
Silk suture is an important non-absorbable and multifilament in nature.
Raw silk is produced by a silkworm larva's cocoon.
Although silk suture is a non-absorbable suture, it loses most of its tensile strength in one year, and is completely absorbed in 2 years. Thus, Silk behaves like a very slow absorbing suture.
Silk suture is dyed black for easier visibility in tissue.
Its handling is easy and can tolerated by body tissues.
Consisted of natural twisted silk encased in an insoluble coating of tanned gelatine or other protein.
It can undergo autoclaving to prevent the ingrowth of tissue cell which may interfere with its removal after use as dermal suture.
Its non absorbable Synthetic Multifilament.
Tensile strength is superior to that braided silk , nylon.
They are the suture of choice its because
they remain in contact with water and
body fluid unlike polypropylene and
stainless steel
They are coated with polytetrafluoroethylene , silicon resin ,
polybutilate
They also impregnated with non toxic
lubricants in order to exhibits smoother
surface ,easy handling and easier passage
thru tissue.
Surgical needle:
1.Eyed Needle: Those that have the hole at the suture side of the needle and that need to be threaded with suture are “eyed”
2.Eyeless Needle:
Those that have the suture crimped within the needle are “eyeless” or “swaged.”
Surgical Stapling Devices:
Ligating Clamps And Clips:
