Abstract
A force measurement device and system, the device being for insertion into an internal body cavity of a human. The probe comprises (a) a probe head having a dimension suitable for insertion into the body cavity; (b) a load cell operatively connected to the probe head such that forces on the probe head are transmitted to the load cell; and (c) a relatively rigid portion joined to the probe head by a relatively flexible portion such that the probe head is flexibly joined to the relatively rigid portion and can move laterally with respect to a longitudinal center line of the relatively rigid portion.
Claims19
A force measurement device for insertion into an internal body cavity of a human, said probe comprising:
- a. a probe head having a dimension suitable for insertion into the body cavity;
- b. a load cell operatively connected to said probe head such that forces on said probe head are transmitted to said load cell;
- and
- c. a relatively rigid portion joined to said probe head by a relatively flexible portion such that said probe head is flexibly joined to said relatively rigid portion and can move laterally with respect to a longitudinal center line of said relatively rigid portion.
A system for determining material properties of internal body tissues, the system comprising:
- a. a probe head having a dimension suitable for insertion into the body cavity;
- b. a load cell operatively connected to said probe head such that forces on said probe head are transmitted to said load cell;
- c. a relatively rigid portion joined to said probe head by a relatively flexible portion such that said probe head is flexibly joined to said relatively rigid portion and can move laterally with respect to a longitudinal center line of said relatively rigid portion;
- and
- d. an imaging means to detect and measure tissue deflection.
