  Introduction Top

A suction infusion device has become the most essential part of closed chamber surgeries of the eye. The existing units are very expensive and are foot controlled. Besides this, the suction head of the instrument is not detach­able. The flute handle is an attempt to economise the device as well as make it more versatile by changing the different types of cannula to suit the requirements of each type of surgery.

  The instrument Top

The instrument is a hollow stainless steel handle with openings at both the ends suitable to connect the suction tube at one end and the aspiration infusion cannula (double cannula) at the other end. It has an opening on the side which can be easily closed with the index finger. The length of the handle is 9.5 cms and diameter 0.75 cm. It has an attached clamp to hold the infusion tube. The diameter of the hollow space is 2 mm and that of the side hole 1 mm. It weighs 30 grams.

  Method of se and its application Top

This simple handle was made by the author formerly for removal of cortical material during extra capsular cataract surgery (i.i a closed chamber method) [1]. It is used along with the cannula and a suction unit. The tube of the suction unit (any suction unit available in the theatre) is attached firmly to the base (proximal) end of the handle. The double cannula (with infusion attached) is fixed to the other end of the handle. The tube for infusion is passed through the clamp. The handle is ready for use. once the suction -nit is activated and infusion is allowed to flow. The infusion flow and suction is adjusted before introducing the cannula into the eye. The double cannula is introduces: into the closed anterior chamber and then into the capsular bag and the cortical material is sucked by controlled application of the index finger at the side opening. The other hand of the surgeon is free to use an iris hook to guide the cannula as well as to prevent the iris and capsule blocking the suction opening of the cannula.

  Uses Top

1. Removal of cortical material in extra capsular cataract surgery.

2. Removal of visco elastic material, small foreign bodies, pus, blood and even worms from the anterior chamber.

3. Lifting and removal of the dislocated lens from the posterior or anterior chamber. For this a modified cannula can be used with wide suction cup.

4. Vitreous lavage and removal of the foreign bodies from the vitreous chamber using long straight double cannula attachment is association with vitrectomy or without it.

  Advantages Top

1. Economical, when compared to a suction unit the cost is negligible.

2. Control of suction is at the finger tip. This means better control for those who are accustomed to use fingers frequently for fine work. Paraplegic and physically handicapped (lower extremity) surgeons can also operate this device.

3. Autoclavable.

4. Less sophisticated. There is practically nothing which can go wrong. Occasionally the tube attach­ment if not firmly attached may get detached.

5. By changing the cannula the handle can be used for different applications.
