tympanoplasty procedures.
◦ The press is designed to instill a degree of
uniformity within the gelatin sponge patch
used to replace the damaged tympanic

sinus.

25. EVE’S TONSIL SNARE
◦ Used for tonsillectomy.
◦ After the tonsil has been dissected till its
lower pole, snare is passed round the tonsil
to engage the pedicle and then firmly
closed.
◦ It crushed and cuts the pedicle thereby
minimizing bleeding.
◦ Wire used in snare is number 25 SWG.

26. ANTERIOR PILLAR RETRACTOR
◦ Used to retract the anterior pillar to inspect
the tonsillar fossa for any bleeding point.

27. CHEST PIECE USED IN
MICROLARYNGEAL SURGERY.

angle of mouth, gets fixed by chest piece, it
is self retaining & larynx is visualized
through binocular operating microscope.

28. PLESTER FLAG KNIFE
◦ a micro ear instrument used to make a
horizontal incision on the external canal
wall skin during elevation of tympano-
meatal flap.
◦ It is also used to elevate tympano -meatal
flap hence is used in middle ear surgeries
like myringoplasty, tympanoplasty and
ossiculoplasty.

29. OESOPHAGOSCOPE

oesophagoscopy.
◦ The length and lumen vary with the age of
the patient.

cysts etc.

34. JACKSONS TRACHEOSTOMY TUBE.
◦ It has three parts: outer tube, inner tube
and an obturator.
◦ Outer tube is not split.
◦ Inner tube can be fixed to the shield of the
outer tube by a lock.
◦ The obturator helps in the introduction of
tube into the trachea.

35. INDIRECT LARYNGOSCOPY MIRROR

held at the back of your throat.
◦ The health care provider shines a light on
the mirror to view the throat area.
◦ This is a simple procedure.

examination.

38. ST CLAIRE THOMPSONS ADENOID
CURETTE AND GUARD

◦ Curette shaves off the adenoid mass while
the guard holds this tissue and prevents
slipping.
◦ Now it has been replaced with debrider
and coblation techniques.

39. UNCUFFED TRACHEOSTOMY TUBE
◦ Uncuffed tubes allow airway clearance but
provide no protection from aspiration.
◦ An uncuffed tube is suitable for a patient in
the recovery phase of critical illness who
has returned from intensive care and may
still require chest physiotherapy, suction via
the trachea and airway support.

the oral cavity while the tongue is
depressed with a tongue depressor.

examine the post nasal space.
◦ The shaft of the instrument is bent to
achieve a bayonet shape, a feature that
helps differentiate it from the indirect
laryngoscopy mirror.

43. UPPER PART OF BRONCHOSCOPE
◦ The proximal/upper part consists of the:
1. Prism light detector(fibreoptic cord is
connected)
2. Main portal of the tube through which
instruments can be passed.
