General Surgery Instruments probes & dilaters

Probes and Dilators

Probes are used to gain entry to small (openings) to get information about their depth, direction and size; they are usually blunt ended. 

Dilators are used to investigate the patency and dilate hollow tubular passages. 

     Infection trauma and surgical accidents can result in healing by second intention in hollow organs this result in strictures. 

     In the past these strictures have been treated by dilatation. 

     The dilators have been made of metal or gum elastic. The agreed gauge has been utilized to ensure uniform size in all the sets. 

     This also helps the surgeon to choose the correct sized dilator. As dilatations are done gradually over a period of the time, the surgeon records the degree of dilatation achieved so as to start at the next level on the subsequent attendance. 

     Corticosteroids can also be used to minimum edema and fibrosis. 

     The dilators in use are:

     •   Lister 

     •   Clutton 

     •   Tuner-Warwick  

     •   Canny Ryall bougie 

     •   Jackson esophageal bougie  

     •   Neoplex  

     •   Bake’s bile duct

Geraral Surgery Instruments Self retaining retractors

Self-retaining retractors, i.e. Travers, Norfolk, Norwich, Balfours, Alms and Jolls have atleast two blades joined by a hinge joint or bar. It is thus possible to create lateral pressure against both margins of the wound. This helps to retain the retractor in position throughout the duration of the operation. 

         Thus freeing the hands of the assistant for assisting the surgeon in other ways. 

         Examples are:

         •       Travers (Fig. 8.98) 

         •       Norfolk (Fig. 8.99) 

         •       Balfour abdominal (Fig. 8.100) 

         •       Joll thyroid (Fig. 8.101).

General Surgery Instruments Catheters & drains

Catheters

The Foley catheter is a plastic two-lumen tube with an inflatable balloon. The balloon is inflated via a small channel.

     Suprapubic cystostomy is an alternative way of draining the urinary bladder. The Malecot catheter is well suited for this purpose. It is a rubber or latex tube with two wings at the tip. The de Pezzer catheter is based on a similar principle except that instead of wings, it has a bulbous end which can be straightened and recoils back when the wire introducer is removed.

     The catheters used are:

     •   Foley 

     •   Gibbons 

     •   Malecot 

     •   DePezzer 

     •   Tiemann 

     •   Secured tube drains 

     •   Corrugated

General Surgery Tubes Catheters

Tubes and Catheters and Drains

Tubes

Without endotracheal tubes modern anesthesia would be unthinkable. The traditional tubes of the Magill pattern are made of red mineralized rubber. Except for the smallest they all have an inflatable cuff near the distal tip to protect the lower respiratory tract form soiling as well as providing an air-tight seal. Each number refers to the internal diameter of the tube in millimeters.

         All tubes in the past have been made of rubber and have been recycled in practice by autoclaving. All these instruments and nasogastric tubes are now made of nonreactive plastic material and come presterilized in packs. These tubes are all disposable and thus do not require recycling. 

         The tubes in use are:

         •       Endotracheal  

         •       Uncuffed oral endotracheal tube  

         •       Negus tracheostomy  

         •       Chevalier Jackso.

General Surgert Needle Holders

Needle Holders

Needle holders are modified box-lock forceps designed to hold curved needles. The surgeon should thus be able to manipulate the needle with ease during suturing near the surface (short needle holders) or at a depth (long).

     Since the function of needle holders is to grasp needles the instruments look like artery forceps:

1.  Serration at the tips to prevent slipping of needle.

2.  Shafts with rings for thumb and fingers.

3.  Locking device.

     Fine needle holders are damaged by large needles and small needles are damaged by large needle holders. The varieties in use are:

•   Mayo needle holder 

•   Gillies needle holder 

•   Naunton Morgan needle holder 

•   Kilner needle holder 

•   Mayo-Hegar needle holder 

•   Microvascular (Doious) needle holder
