How are Drilled End Needles the least traumatic to the skin?

Skin trauma is becoming less of an issue within the Suture industry due to the constant technological and practical improvements carried out to both the ‘sharps’ instruments involved and the technician. The problem of post implications to a procedure is now a rarity, but that does not mean that casualties to the skin don’t still occur occasionally in practice.

Of course one has to remember that a sharp metallic edge impressing the skin tissue is not really natural, but has to be undertaken for the good of the patient. As one also has to remember a serrated blade contacting the skin will also leave possible scarring.

All needles in Suture now come with minimal chance of traumatising the skin surface or internally beyond, but however according to industrial research there is a favourite in causing the least shock factor. The Drilled End needle.

Fabulous news to hear, but how has this conclusion come to fruition?

Even as far back to the year 1977 the Drilled End has been regarded one the safer modes of Suturing. According to sourced material from the American Cyanamid Company, it is the lack of a sharp corner to the Drilled End that allows the practitioners placement and exiting of the needle to the skin more conventional and specific. Thus creating only a slight countersink to the impressed area.

This factual declaration sounds encouraging to the patient, but it has to be remembered that technology and standards of safety were very different back in the 1970s to the present day. Is it not possible that the innovation of fellow Suture needles have since surpassed the Drilled End? Of course it is. Yet more recent research carried out among the profession keep the American Cyanamid Company’s suggestions alive and referable.

Suru.com, an Indian distributor of Stainless Steel Suture equipment, regard the Drilled End as a piece of kit for maximum handling and strength as of 2014. Fantastic and reassuring news for worriers, but what gives this needle premium handling and strength? Thus more control for the professional over skin trauma. In the words of Suru.com it is the tempering of the securing system that encourages the drilled needle attachments to be stronger than other needles and less abrasive.

Other needles however have attempted to keep up and are heavily influenced by the raised standards of the Drilled End.

The Hypodermic needle for one may be designed to gauge the skin surface, but innovators have taken time in ensuring patients with the choices of Regular or Short Bevel and Intradermal or Pencil Point. All with tubing for Regular, Thin, Extra-thin or Ultra-thin walls.

The other of the influenced is the Bespoke needle, a reliable and critical component to wound closures.

All this care into making sure the needle proceeds to a high-standard service and that strategies prevent post skin trauma to all capabilities is a significant relief to all patients involved. This suggests that all Suture needles are less evasive nowadays and less of an impact towards the skin surface. Reverting back to the initial question however. How are Drilled End Needles the least traumatic to the skin?

All of the above suggest that Suture needles are getting better in preventing skin trauma, but that the Drilled End is still the best. How you might ask. The Drilled End is firstly a rounded needle blade, meaning that it can be inserted delicately and is notionally easier to manage around wounds in comparison to the direct downward insertion of the straight needle which can only move that one way.

The Drilled End is ribbed not sharp, which reduces slicing damage to the tissue and increases the stiff stability of the needle holder. Equalling in better control for the practitioner to raise levels of safety.

Adding to each of these characteristics is the simple fact that the Drilled End is coated in Silicone. This Polysilaxane is a cure lubricant to stabilise penetration. Conclusively, it is the specific lubricant of the Drilled End that encourages the least trauma to the skin in comparison to other Suture needles.
