Microcannulas, also called micropipettes or microneedles, are tiny tubes that can be used to transfer biomaterials between two experimental containers. Cannulas are typically obtained in glass needles with diameters less than one-hundredth of a millimetre across. Microcannula tips have been most widely applied in biomedical engineering because they can manipulate very small quantities of fluids and tissue samples. However, most people prefer grabbing details about Needle Vs Cannula to decide to select one.

They are commonly used in cell culture and tissue engineering applications, where they are used in a variety of ways to transfer cell lines. However, microcannulas are also used for a variety of other applications within research that may involve manipulating DNA or absorbing liquids into pill-like forms. Microcannulas have several advantages over larger cannulas and needles, one of which is their ability to manipulate minute amounts of fluid or tissue samples. They can also be quickly submerged within fluids or tissue samples without causing any damage.

Microcannula Technique

  • This technique is primarily used in vaginal reconstructive surgery and involves a small, catheter-type instrument inserted through the vagina to remove tissue. It is used when fibroids, STDs, or cancer cause large amounts of adhesions or scarring. It is also sometimes used when disorders such as lichen sclerosis lead to solid scarring.
  • It is not used when the patient has an active infection, bleeding disorder or cancer. However, this technique has been increasing in popularity with time. It can also remove small samples of vaginal tissue and lymph nodes to biopsy them. The procedure can be done either under general anaesthesia or as a day case procedure using sedation/local anaesthetic.
  • The area is cleaned, and sterile conditions will be put into place. Next, a speculum is put in place, and the vaginal wall is examined for any abnormalities.  After this, a series of dilators are used to open the area up so that the surgeon can reach any hard-to-reach places. Next, the microcannula itself is inserted into the vaginal wall, and tissue samples can be taken at this time. Finally, the surgeon will remove adhesions and scar tissue with an oscillating saw, curettage knife or laser.
  • Follow-up after the procedure usually requires no type of treatment. The wound is closed with a regular surgical stitch, and the patient will go home within a few hours of surgery.  Aftercare generally involves no treatment. Most patients do not experience any other long-term side effects from this surgery. Some may be concerned about the pain after the surgery, but they are quickly relieved as they recover from the procedure itself.

The people who doubt the Microcannula technique can pay attention to the above details as it will help them grab a better understanding of this technique. Once people know about this technique, it will be very beneficial for them during decision-making and have better results. Furthermore, it will help you better understand, allowing you to build your trust towards this tool and motivate you to go for it.
