The present invention relates to a stand equipped with a counterbalance unit, i.e., a stand consisting of links, joints, a front link, and a counterbalance unit. Therefore, even when various medical apparatuses including such as a microscope, etc. are used, a stable counterbalance can be maintained and the degree of freedom of movements of the medical apparatus can be easily adjusted according to the purpose of users.

Stand equipped with counterbalance unit

A stand includes first to fourth links, first to fourth joints, a front link, first to fifth extension links, and first to fourth extension joints. The first to fourth links are arranged in a parallelogram configuration, wherein the first and third links are arranged on opposite sides and the second and fourth joints are arranged in a diagonal direction. The front link extends from the first link. The first extension link is rotatably connected to the second joint. The second extension link is rotatably connected to the first extension joint. The third extension link is rotatably connected to the second extension joint. The fourth extension link is arranged between the third extension joint and the fourth extension joint. The fifth extension link is arranged between the first joint and the second extension joint. The first, fourth, and fifth extension links are in parallel with one another.

An endoscope apparatus is provided. An endoscope apparatus includes a slave device including a plurality of drive motors configured to adjust insertion and insertion direction of an insertion tube of an endoscope, and a plurality of load sensors provided on the plurality of drive motors; and a master device including displacement sensors configured to generate signals for driving the drive motors according to an operator manipulation, and resistive motors configured to operate based on loads detected by the load sensors. The drive motors produce drive forces according to the signals generated by the displacement sensors and the resistive motors produce resistive forces corresponding to the operator manipulation based on the loads detected by the load sensors.

Endoscope apparatus with slave device and master device

A stand for medical optical instrument capable of easily extending, adjusting easily a counter balancing according to a change of a weight of medical optical instrument such as microscope, as well as, maintaining stably a counter balancing regardless of a position of medical optical instrument. The stand for medical optical instrument includes a first to fourth links having a first to fourth turning joins, wherein the first to fourth links are rotatably coupled to each other in a parallelogram shape and the second turning joint is rotatably coupled to a holding unit, a carrier arm extended from the fourth link; and a counter balancing unit coupled to the first and second links, wherein the counter balancing unit is rotated in connection with the first and second links on the second turning joint according to the rotation of the carrier arm, and capable of maintaining a counter balancing of the carrier arm by compensating a torque generated in the second turning joint according to a medical optical instrument installed on the front link.
