DISSECTING FORCEPS

DISSECTING FORCEPS
TWO TYPES:
1. Non-tooth or Plain
2. Toothed
Also named after their designers, e.g…
Lane’s
Victor Bonney’s
Millin’s
Gillies’

PLAIN DISSECTING FORCEPS
Identification :
 Handles have spring like action
 Few ridges on the central part of outer
surface of the handles to give better grip
 Blades are serrated transversely on
inner aspect, for better grip to tissue.
These serrations also help in holding
needles during the taking of bites.

VICTOR BONNEY’S DISSECTING FORCEPS
Identification :
Handles have spring like action
Few ridges on the central part of outer surface of
the handles to give better grip
Blades are serrated transversely oninner aspect, for
better grip to tissue.
These serrations also help in holding needles
during the taking of bites.
Bonney Tissue Forceps are thumb forceps used for
grasping heavy tissue or bone.

RETRACTORSTYPES:
1.Plain Retractors
2.Self Retracting Retractor
These are of the following types:
oSingle bladed
oDouble bladed
# Both blades are on same sided
# The blades are oppositely placed

USES:
Act as key instruments for
obtaining exposure.
Better exposure helps one to see
the operation field in a better way
and curb out damage to adjacent
tissues.

RETRACTORS

PILES HOLDING FORCEPS
Pile Forceps is ideally used to grasp hemorrhoids.
The jaws are slightly curved and contain blunt
tips to provide minimal trauma to the area being
grasped.
For greater grasping ability, one of the jaws
contains grooved serrations and fits perfectly into
the other jaw when clamped.
The forceps also contains a ratchet on the ring-
handles to help keep the instrument in place if
needed.

SPONGE HOLDING FORCEP
Sponge Forceps are a ratcheted, finger ring instrument used to
grasp tissue or hold sponges.
The instrument is used to hold gauze or cotton that is precisely
wrapped around the tips and the ratcheted is locked to secure a firm
grip.
This creates a sponge stick that can be used in any type of
procedure to absorb blood and excess fluids from the surgical site
and surrounding areas.
This product is straight with fenestrated, serrated tips and a length
of 7 inches.

Needle Holder is handcrafted from German stainless steel
and tungsten carbide inserts that provides control, precision
and a dependable non-slip crosshatched surface.
The Mayo-Hegar is one of the most commonly used types
of needle holders in operating rooms, and is offered in both
right and left-handed variants and multiple lengths.
The serrated jaws and gold-plated ratcheting handles are
available in a variety of lengths as well as several left
handed models.

GASTRIC CLAMPS

A lumbar puncture (or LP, and colloquially
known as a spinal tap) is a diagnostic and at
times therapeutic procedure that is performed
in order to collect a sample of cerebrospinal
fluid (CSF) for biochemical, microbiological,
and cytological analysis, or very rarely as a
treatment ("therapeutic lumbar puncture") to
relieve increased intracranial pressure.
Lumber puncture needle

• The most common purpose for a lumbar puncture is to collect
cerebrospinal fluid in a case of suspected meningitis.
• Young infants commonly require lumbar puncture as a part of
the routine workup for fever without a source, as they have a
much higher risk of meningitis than older persons and do not
reliably show signs of meningeal irritation (meningismus).
• In any age group, subarachnoid hemorrhage, hydrocephalus,
benign intracranial hypertension and many other diagnoses
may be supported or excluded with this test.
• Lumbar punctures may also be done to inject medications
into the cerebrospinal fluid ("intrathecally"), particularly for
spinal anesthesia or chemotherapy. It may also be used to
detect the presence of malignant cells in the CSF, as in
carcinomatous meningitis or medulloblastoma.

Contraindications• Lumbar puncture should not be performed in the following situations
• Idiopathic (unidentified cause) increased intracranial pressure (ICP)
– Rationale: lumbar puncture in the presence of increased ICP may cause uncal herniation
– Exception: therapeutic use of lumbar puncture to reduce ICP
– Precaution
• CT brain is advocated by some, especially in the following situations
– Age >65
– Reduced GCS or conscious state
– Recent history of seizure
– Focal neurological signs
• Ophthalmoscopy for papilledema
• Bleeding diathesis
– Coagulopathy
– Decreased platelet count (<50 x 109
/L)
• Infections
– Skin infection at puncture site
– Sepsis
• Abnormal respiratory pattern
• Hypertension with bradycardia and deteriorating consciousness
• Vertebral deformities (scoliosis or kyphosis), in hands of an unexperienced
physician or physician assistant.[

DOYEN’S SHORT CROSS-ACTION TOWEL CLIPDOYEN’S SHORT CROSS-ACTION TOWEL CLIP
Towel clips/clamps have handles which have a
lock in them.
The tip of the clip can either be pointed or
curved and some even have teeth to provide a
good grip.
Towel clip is a kind of towel clip and it is used
to secure draping and towels which are used
while a medical procedure is being conducted.

PROCTOSCOPE
A proctoscope is a short,
straight, rigid, hollow
metal tube, and usually
has a small light bulb
mounted at the end. It is
approximately 5 inches
or 15 cm long,
while a rectoscope is
approximately 10 inches
or 25 cm long.
.

Proctoscopy is a common medical procedure in
which an instrument called a proctoscope (also
known as a rectoscope, although the latter
may be a bit longer) is used to examine the
anal cavity, rectum or sigmoid colon.
During proctoscopy, the proctoscope is
lubricated and inserted into the rectum, and
then the obturator is removed, allowing an
unobstructed view of the interior of the rectal
cavity.

PROCTOSCOPE….
This procedure is normally done to inspect for,
hemorrhoids or
rectal polyps.
Modern fibre-optic proctoscopes allow more
extensive observation with less discomfort
