The invention is an improved yo-yo that features two side assemblies that sandwich a center axle onto which the yo-yo's tether may be secured. According to a first embodiment, each of the side assemblies preferably includes a releasable, disk-shaped rim piece. By replacing one set of replaceable rim pieces with another, a user can quickly and easily change the yo-yo's shape, look and / or functionality. To remove a rim piece, one first removes a lock ring that is secured to the rim piece and blocks a number of openings that lead to grooves in a center-located hub. Next, one employs a twisting movement of the rim piece to cause a number of tabs attached to the rim piece to slide in the hub's grooves until the tabs are aligned with the openings. The rim piece can then be disengaged from the yo-yo.

The invention discloses a three-dimensional human body evaluation template, which comprises forward and backward swinging dials, inward and outward swinging dials, twisting movement dials, inward and outward wrist joint flexion movement dials, upward and downward ankle joint movement dials, elbow joint dials and forward and backward knee joint swinging dials, wherein the forward and backward swinging dials and the inward and outward swinging dials are arranged at shoulder joints and hip joints; the twisting movement dials and the inward and outward wrist joint flexion movement dials are arranged at wrist joints; the twisting movement dials and the upward and downward ankle joint movement dials are arranged at ankle joints; the elbow joint dials are arranged at elbow joints; and the forward and backward knee joint dials are arranged at knee joints. According to the template, angle measurement devices are arranged at human body joints, and are linked through pointers to read movement angles of the joints, and non-movement areas, practicable movement areas and comfortable movement areas of the dials are distinguished through red, yellow and green according to a human engineering standard, so that operating comfort can be directly identified, position evaluation and human body evaluation characteristics are combined, and the template is simple and convenient.

The embodiment of the invention discloses a device for measuring conduit interventional force and torque in a cardiovascular interventional operation in real time. The device comprises an outer support, an inner shaft, force sensors, bolts and nylon fasteners, wherein each force sensor is adhered to the inner circumference of the outer support; the inner shaft is placed in the outer support with the force sensors; the outer wall of the inner shaft is in interference contact with each steel ball of each force sensor; male end and female end nylon fasteners suitable for winding a thumb or a forefinger are cut; holes are formed in at the bottom ends of the male end and female end nylon fasteners in a cutting way to enable the bolts to pass through; the bolts pass through a female end thread gluing, an inner shaft screw hole and a male end thread gluing and are screwed by using nuts; and the nylon fasteners are used to adapt to the sizes of different fingers of operators, so that the operator wears the device to clamp a conduit in the operation to ensure that the conduit does translation or twisting movement. By using the device, stress information in an operation process can be monitored, and the safety of the operation is improved; and by acquiring the operating force and the operating torque of an experienced physician, the device provides quantitative evaluation standards for a virtual training system of the cardiovascular interventional operation at the same time.
