1 Chapter 14 Anatomy and Function of a Table Top Gag Adjusting the Gag for use. Access to the cheek teeth of rabbits is a problem recognised by all involved in their dental care. A combination of the diets fed to pet rabbits and the head shapes selected for, both contribute to malocclusion issues, requiring treatment which necessitates access via the (small!) rabbit mouth. The table top gag is designed to hold the rabbit at the optimum angle for easy access. The traditional gag tends to drag and tilt the head sideways The addition of the light makes a huge difference to visibility, without the need for more hands in the way. The platform of the gag itself is now made of Teflon. This has very different thermal properties from the original metal base. It is a far better insulator and helps retain the patient s body heat during anaesthesia. Identify on your gag: A - Platform Angle Adjustment B - Bottom bar adjuster C - Top bar height adjuster (left & right) D - Top bar in-out adjuster (left & right) How to assemble the Table Top Gag Remove all packaging. Identify all the components as shown above. The clamp, spanner and light are included if you have selected that option. On the Teflon platform, loosen the 2 screws Y (picture at top of page) at either end of the channel at the front end of the platform. Insert the flat bar at the base of the gag assembly into the channel. The correct way around is with the adjustment screws D to the short front end of the platform. The loops should point back along the platform towards the hinge. Easy and common to put this in the wrong way around! Attaching the Light Identify screw Z at the top of the shorter post. The longer of the 2 clamp screws inserts into the top of this screw. Loosely fasten both clamp screws. Slide the pencil handle of the light into the clamp. The handle should sit parallel to the base, with the light outlet forwards as illustrated. Tighten both screws to hold the handle in position. The flexible neck of the light can then be adjusted as required. Rabbit in position, with additional cheek dilator in place Care of the Table Top Gag Routine cleaning of the Table Top Gag with environmental detergents and disinfectants is adequate. For best results use cleaners designed for stainless steel on the metal components, and avoid iodine based compounds on the Teflon base as this may result in staining. This is purely cosmetic and will not affect the gag s performance. All moving parts should be lubricated regularly with either surgical instrument lubricant or Teflon drops, to keep them moving freely. The complete gag is autoclavable. If available, use the 121 setting although 135 can be used. Take the top assembly off the platform before autoclaving. Pack the platform flat, as far as possible from the heater element, and do not stack other items on top. The platform should be left flat to cool after autoclaving, to avoid any distortion. 348

2 RODENT DENTISTRY 14 Table Top Rabbit Gag Rodent Mouth Gag Without this gag examination and treatment of rabbit molars is virtually impossible. RODENT MOUTH GAG Rodent Mouth Gag This version of our well known gag now has a white Teflon platform which makes the gag warmer for the anaesthetised small patient and rather cheaper than the original. It is easy to clean and may be autoclaved. TABLE TOP RABBIT GAG Table Top Rabbit Gag Table Top Rabbit Gag and LED Light DENRODKIT Table Top Rabbit Gag, LED Light and Full Hand Kit (Rod2 - see page 328) LED Light For Table Top Gag Lightweight Rodent Mouth Gag Less bulky and less powerful than the standard Rodent Gag. Cheaper too. LIGHTWEIGHT RODENT MOUTH GAG LW Rodent Mouth Gag Lightweight LWS Rodent Mouth Gag Lightweight and Small Cheek Dilators The Small Dilator is also useful as a small gag for guinea pigs and chinchillas. 14 Illumination of the inside of the rabbit mouth is difficult without the hands of the surgeon getting in the way. The Rabbit Gag LED Light simply clips into the retaining mount which screws onto the threaded height adjustment control. The flexible neck of the Light can be adjusted for best effect. The powerful white LED lasts for approximately 100 hours on a set of AAA batteries. Also useful as a focal examination light elsewhere in the clinic. Fits all table top gags.

4 RODENT DENTISTRY 14 Rabbit Bur Kit Crossley Incisor Luxator Designed by David Crossley to extract the very large rabbit incisors. Removal avoids the requirement for repeated cutting of overgrown mal-occluded incisors. Shape of Luxator matches tooth shape. A smaller version is available for guinea pigs and rats. Three burs have been selected by David Crossley as being suitable for the reduction of rabbit and chinchilla molar teeth. Our Rabbit Bur Kit includes two of each bur in a Stainless Steel Autoclavable Block. All are HP fitting to fit into the 1:1 Straight Nose Cone (not included). When using the Long Bur (HL563) use the Soft Tissue Protector to shield tongue and cheek. The diamond version of the very long cross cut bur cuts with less trauma and less heat than the carbide equivalent.

5 Root Tip Extraction Forceps Rabbit Dental Kits Actual Size Most chronic abcesses around the head of a rabbit are related to infected tooth roots. Removal of the offending root is a prerequisite for successful treatment. Designed by Frances Harcourt-Brown these modified needleholders are used to locate and lock onto the root tip via the abcess. ROOT TIP EXTRACTION FORCEPS Root Tip Extraction Forceps 160mm If you are setting up or have no rabbit/ rodent equipment you may wish to purchase a Set, which offers considerable savings and is supplied in an Stainless Steel Autoclaveable Case. Basic Kit (ROD1) contains: Rodent Gag Long Reach Cheek Dilator Incisor Luxator Molar Cutter Fine Rasp Antibiotic Impregnated Polymethacrylate Beads (AIPMMA) Full Hand Kit (ROD2) contains: Rodent Gag Small Cheek Dilator Large Cheek Dilator Long Reach Dilator Incisor Luxator Molar Luxator Molar Extraction Forceps Diamond Rasp Rodent Spatula Molar Cutter Hand & Motor Kit (ROD3) contains: As Full Hand Kit PLUS: Rabbit Bur Kit Soft Tissue Protector Diamond Disc Diamond Disc Protector This Kit also requires a Straight Nose Cone, plus a Micromotor, Air or Electric Drive. Management of chronic local infections may benefit from the insertion of Antibiotic Impregnated Polymethacrylate (AIPMMA) Beads. The Beads are manufactured from sterile bone cement with the addition of appropriate antibiotic. Indications include osteomyelitis and abcessation in the rabbit. Veterinary Instrumentation offers two Kits for the preparation of AIPMMA Beads. One Kit uses cement with no antibiotic; choice of antibiotic will depend upon bacteriology and sensitivity. The other Kit uses cement containing gentamycin which is the preferred choice of antibiotic for many infections but is toxic when administered parenterally. Both Kits contain sufficient material for approximately 100 Beads. Full instructions are included.
