Angulated Blade Breast Dissectors, Insulated and Non Insulated

What the Angulated blade breast dissector is

The Angulated blade breast dissector is a hand instrument used to open and shape the implant pocket in breast surgery. Surgeons also call it an angulated breast dissector, an insulated breast dissector or an angled breast pocket dissector. It is made by Adas Instruments in high quality medical grade stainless steel, and it is reusable and fully autoclavable.

The angulated blade is what this pattern is for. A straight blade holds a straight line. An angled one follows the curve of the chest wall and reaches around it from an incision far away.

The work a breast dissector does is always the same in principle. A pocket has to be opened along a plane that already exists, without cutting through it and without tearing the tissue on either side. A blunt end pushed along that plane separates it and leaves the small vessels intact, which is why the field stays dry. The width of the blade, the shape of the shaft and how far the end has to travel decide which pattern a surgeon picks up.

Key design features of the Angulated blade breast dissector

• Angulated blade that follows the curve of the chest wall
• Insulated shaft breast dissector build, or non insulated, chosen at order
• Two builds, 33 cm with a 22 cm working length and 42 cm with a 30 cm working length
• Blunt end that separates a plane instead of cutting it
• Reaches the pocket through a transaxillary or inframammary incision
• High quality medical grade stainless steel, reusable and autoclavable

The handle is flat and knurled rather than round. A flat handle tells you which way the blade is facing when the working end is deep in a pocket and out of sight, and the knurling holds when a glove is wet. The shaft runs into the blade with no step, so there is no shoulder to catch on the edge of an incision and nothing for protein to sit in after a case.

Angulated blade dissector sizes and build options

Every size below is a size we actually ship. Imperial figures are given beside the metric because United States buyers search in inches.

Nothing is listed above that we do not hold. If a build you need is not in the table, ask, because a change of length or blade width is a tooling change rather than a new instrument.

Uses of the Angulated blade breast dissector by specialty

The Angulated blade breast dissector appears on the same trays across these specialties because the job is the same one each time, opening a plane bluntly and holding the pocket where the surgeon meant it to stop.

The specialty name and the procedure name are both worth knowing when you order, because catalogues file this pattern under whichever of the two the buyer used. They are looking for the same instrument.

Tissue planes the Angulated blade breast dissector works in

A breast dissector handles no suture and no needle. What decides the choice of pattern is the plane it has to open, how far the working end has to travel to reach it, and how much room there is to move once it is there.

Force is the part nobody writes down. A subglandular plane in a young patient opens with almost nothing, while a capsule in a revision case needs a firm push and a stiff shaft behind it. Match the blade to the plane and the instrument does the work instead of your wrist.

How the Angulated blade breast dissector compares with other patterns

These four sit next to each other on a breast tray and they are not interchangeable.

Surgeons who use this pattern usually also hold the spatulated blade breast dissector, the oval spatulated blade breast dissector and the Jacobs transaxillary dissector. The closest relative in the range is the spatulated blade breast dissector.

If you are building a breast tray from scratch, the usual answer is two dissectors rather than one. Something long for the far edge of the pocket and something shorter with more feel at the tip covers almost every case.

Materials and finish

The instrument is made in high quality medical grade stainless steel. The steel itself is made to a German specification. The working face is ground and satin finished, which cuts glare under the lights in an operating room and keeps the end readable against wet tissue. There is no coating to chip and nothing on the shaft to trap protein.

Stainless steel is chosen here for a reason that has nothing to do with appearance. A long shafted dissector is pushed hard at full extension, and a shaft that is too soft will take a set and stay bent, which throws the blade out of the plane on the next pass. A shaft that is too hard will crack at the neck instead. The grade used sits between the two.

Angulated blade breast dissector care and sterilization

Rinse the instrument in cool water straight after use so blood does not dry on it. Clean it with a soft brush and a neutral pH enzymatic detergent, rinse in deionized water, then dry it completely. Steam autoclave at 134 degrees Celsius. Lay it flat in the tray with nothing resting across it, because an instrument loaded sideways in a crowded tray is the one that comes back out of true.

Look at the working end against the light before every case. A blunt end should be smooth with no flat spot and no nick, and the shaft should still be straight when you sight down it. A dissector with a nick on the end is what tears a pocket two cases later, and it costs nothing to check.

Ordering and wholesale

This pattern is supplied by Adas Instruments to hospitals, surgical distributors and OEM buyers, in single units and in bulk. The item code is confirmed on the quotation and it is printed in the size table above so a procurement search finds it. Backorder items dispatch in 10 to 12 working days. Every instrument carries a three year replacement against manufacturing defects.

For wholesale and OEM orders, instruments ship unpackaged in bulk or individually poly bagged, and laser marking with a distributor code or a hospital asset number is available. Tell us the quantity and the marking you need and the quotation comes back with the lead time for that run.

Production is controlled under an ISO 13485 quality management system. The instrument is CE marked.

Frequently asked questions

What is an angulated blade breast dissector used for?

It opens and shapes the implant pocket in breast augmentation and reconstruction. The angulated blade is what it is chosen for: the chest wall is curved, and an angulated blade stays in the plane where a straight one lifts out of it.

What does the insulated shaft on a breast dissector do?

It isolates the electrical current. With an insulated breast dissector, monopolar or bipolar energy travels down the shaft and only leaves at the tip, so a vessel deep in the pocket can be coagulated without a burn at the incision or on tissue the shaft is touching.

Should I order insulated or non insulated?

Insulated if cautery is used in the pocket, which in augmentation it usually is. Non insulated if the dissector is only ever used for blunt work and the energy comes from a separate instrument.

What is the difference between overall length and working length?

Overall length is the whole instrument. Working length is the part that goes inside, measured from the tip to where the handle starts. On this pattern 33 cm overall gives 22 cm of working length, and 42 cm overall gives 30 cm.

How do you clean and sterilize an insulated dissector?

Rinse in cool water straight after use, clean with a soft brush and a neutral pH enzymatic detergent, rinse in deionized water, dry fully, then steam autoclave at 134 degrees Celsius. Inspect the insulation along its whole length before every case, because a crack in it is the one fault that can burn a patient.

Surgeons who work with the Angulated blade breast dissector usually compare it against the spatulated blade breast dissector, the oval spatulated blade breast dissector and the Jacobs transaxillary dissector. It sits beside the Iconoclasts breast spreaders on the same tray. The whole family sits in dissectors and elevators, and this pattern is also listed under breast surgery instruments.
