Basic Trocar System

The new Basic Trocar System was developed in response to a request for a more simplified set of trocars. Clinical feedback from many surgeons had shown that the already existing Universal Trocar System with its high number of components can be too overloaded for their needs in the OR.

The simplified Basic Trocar System was created by eliminating cannulae and drill guides from the existing system, and also by consolidating the functionality of three retractors (Malleable C-Retractor, Cheek Retractor Blade, and Cheek Retractor Ring) into one new instrument (Cheek Retractor Forceps). In addition to reducing the amount of instruments, a selection of new features has been included.

Snap Lock Feature

The Basic Trocar Systems drill guides and obturator fit into the cannily using a snap lock feature. This feature prevents unintentional decoupling of the instruments from the cannula, therefore preventing the instruments from dropping.

To remove a drill guide or obturator from the cannula, the instruments head should be compressed with thumb and forefinger and then extracted.


Rotating Trocar Handle

The Basic Trocar Handle can rotate around the cannula to allow for more space at the operating site. To maintain control over the instrument, the handle engages like a ratchet in discrete arcs instead of freely rotating.


Cheek Retractor Forceps

The new Cheek Retractor Forceps allow the surgeon to retract buccal tissue quickly and easily. The forceps combine the functionality of the former Malleable C-, Blade- and Ring-Retractors. The recommendation of several surgeons, the forceps incorporate the same width and angles as the existing Cheek Retractor Blade. The forceps can be disassembled into two pieces, to allow for easy cleaning and sterilization. The forceps interlock is asymmetrical, so it cannot be assembled incorrectly.

To prevent slippage, the threads on the inner surface of the forceps jaw affix it to the cannulas shaft very tightly.


Drill Bits

The Basic Trocar Set includes three drill bits. Each has a shaft diameter of 2.4 mm, a 30 mm fluted length, and markings indicating drill size and hole depth. The commonality of their diameters and lengths enables all three drill bits to be used with any of the basic drill guides.
