Inspecting and Unbending Surgical Needle Holders

Most surgeries require scissors in medical and needle holders. For doctors, their assessment of the quality of surgical instruments depends on the sharpness of the scissors and the convenience of the needle holder for suturing the wound. Needle holder is an important tool for incision suture.



1. Type of Needle Holder

The needle holder applied in different operations is different, but its basic components are the same.


Surgical needle holder is usually made of stainless steel with stainless steel or tungsten carbide inlaid clamp end (golden). The tungsten carbide clamp end can be replaced. If the finger ring of tungsten carbide needle holder is gold, it indicates that there is tungsten carbide in the end of the clamp. Gold is only to distinguish whether it contains tungsten carbide or not, which will not affect the utilization of the device. Tungsten carbide is much harder than stainless steel. Its wear and tear is more slowly and can be replaced after wear and tear. The clamp end of the non gold needle holder is made of stainless steel and cannot be replaced. Once its clamp end is worn, the entire instrument must be replaced.

Some needle holders are blue. The blue needle holder indicates that the instrument is made of titanium. Titanium is usually gray, and the titanium needle holder needs anodizing to turn blue. This process reduces the surgical glare reflected by the instrument. Titanium needle holder is lighter than stainless steel needle holder, which relieves hand fatigue during long operation. This kind of needle holder is non-magnetic, corrosion resistant and harder than stainless steel. These properties make titanium instruments more expensive.


The needle holder with smooth clamp end is to clamp extremely fine suture needle, and the clamp end has no grain. The most common type of needle holder is the Halsey type or Webster type. The clamp end of diamond sand is with a black handle, and fine powder of tungsten carbide is added to the clamp end by an electric spray gun with carbide electrode. The clamp end of needle holder with green handle is ceramic.



2. Common Misunderstanding

A common mistake is that the needle holder of tungsten carbide clamp end cannot be cleaned by ultrasonic cleaning machine, because the clamp end will fall off during the cleaning process. In fact, although the clamp end may fall off the instrument during ultrasonic cleaning, they can be reassembled, and the ultrasonic cleaning machine itself will not damage the needle holder. If the clamp end falls off, it is most likely to indicate that it needs to be repaired. It is more optimistic that the clamp end falls off during the cleaning process than during the operation.


Check the straight needle holder daily for wear like other surgical instruments. One of the important responsibilities of each technician in the Central sterile supply Department is to ensure that there is a quality system to ensure that all surgical instruments are in the best condition when they are delivered to the sterile area.

3. Test Checkpoint

In addition to routine inspection and maintenance, technicians of the Central sterile supply Department should check the clamp end of the lap needle holder before putting it into the operation tray. A simple and quick method is to open the ring and check the clamp end. All clamp ends will wear over time. If it is found that there is a gap or wear on the clamp end of the needle holder, it should be stopped immediately for maintenance or replacement.


Another common problem for inspection is cracks at the fine needle holder bearing. Check both sides of needle holder bearing for cracks. Usually, the small needle holder will crack when it is used to clamp the larger needle. Another reason may be the lack of sharp-nose forceps in the orthopedic equipment group, so needle holders are applied to pull needles and strands. This is not the purpose of the needle holder and these cracks cannot be repaired. The needle holder with cracks should be stopped and discarded immediately.


Another important part of vascular needle holder inspection is to check the ratchet closure at each position. During the test, gently buckle each ratchet to observe whether the needle holder matches. If it does not match, place the needle holder on the first ratchet and gently tap it on a flat table (mainly do not use the palm). If the ratchet closes after three to four taps, flip the instrument and repeat the test. If the ratchet spring is opened during the test, it should be sent for repair.


The needle holder instrument with excellent quality and good usage laid a good foundation for the suture and recovery of surgical wounds.
