摘要:
This invention relates to an articulated iron cap for a hand plane. The iron cap has a means for pivotally mounting to a hand plane and an articulating means for tensioning an iron in the hand plane whereas the articulating means is further configured as a chip breaker. The iron cap for the hand plane is configured to mate to either a beveled down iron or a bevel up iron. One embodiment of the invention has a chip breaker configured with a three dimensional axis for engaging a plane iron. In addition, the chip breaker is configured to pivot approximately perpendicular to the longitudinal axis of the hand plane. Furthermore, a nose piece on the chip breaker is configured to pivot so as to align with the grind angle on the iron. This invention places a large mass chip breaker towards the cutting edge of the iron which allows for preloading the iron and dampening vibration of the iron. In turn, this all creates a smoother more accurate cut and requires less effort to use.

This invention provides an angle gauge that, when used in conjunction with a caliper or other linear measuring device, improves both the precision and ease with which angles can be measured and set by allowing the user accurately to measure and set angles in fractions of degrees. Using the gauge, an angle formed by the gauge may be determined or set by reference to the linear distance measured by the caliper. Calculations or tables can be used to convert the linear measurements into the angle setting or measurement with great accuracy, or the capacity to calculate the angle corresponding to the linear measurement can be built (i.e. programmed) directly into the device.

The present disclosure concerns embodiments of an operating support that supports a surgeon in a sitting position straddling a patient. By straddling the patient, the surgeon is ideally positioned to perform certain types of laparoscopic surgery, such as pelvic surgery, which requires the use of relatively long surgical instruments. The operating support supports the surgeon in a more ergonomically correct position that reduces the stress and strain on the surgeon's body as compared to the conventional technique of performing laparoscopic surgery in a standing position at one side of the operating table.

A variable cutting angle hand plane is provided. The variable cutting hand plan has a base unit configured for holding an iron, wherein the base unit has a sole and a throat extending through the base unit to the sole. The base unit has an adjustable frog for supporting the iron at multiple angles with respect to the sole. A means for engaging the iron is used for holding the iron against the adjustable frog. The hand plane may have an adjustable throat. There may be a means for indicating the approximate angle of the adjustable frog.
