This invention provides a guide for surgical purpose, comprising: a long column body, being in a hollow shape, an upper side thereof having a semi-cylinder, a bottom side thereof having a cuboid, and an inside thereof being provided with an elongated slot, in which an interior of the semi-cylinder is in communication with an interior of the cuboid; a wing-shaped part, being in a wing shape, and disposed at one end of the long column body and engaged with one side of the cuboid and extending from both ends of the one side of the cuboid, for grasping during surgery; a limiting piece, being in a ring shape and socketing the other end of the long column body and engaging with the other side of the cuboid, for withstanding the tissues during surgery; and a replaceable expander, being disposed in the elongated slot, for expanding and opening a surgical incision of tissues, wherein the replaceable expander is replaceable with another expander of different dimension in a stepwise manner via the one side of the cuboid proximate to the wing-shaped part and inside the elongated slot, thereby for expanding.

Guide for surgical purpose

The present invention relates to a non-invasive positioning system for screwing and fixing a bone, where a intramedullary nail is inserted to marrow of the bone, and the intramedullary nail comprises a wall and at least one through-hole through the wall for screwing and fixing by at least one corresponding set screw, the system comprises: an in vitro locator having at least one light source to emit a laser with a wavelength to the muscle tissue to form an incident light and running through the muscle tissue and the bone to form a penetrated light, an optical holder having an optical lens and a positioning ring portion for removably disposing the optical lens, wherein the focusing spot of the incident light, the focusing spot of the penetrated light, and the at least one through-hole are aligned in a line to confirm a linear position for screwing and fixing the intramedullary nail.

Non-invasive positioning system and method for screwing and fixing a bone

A bone nail apparatus includes a bone nail, a light source unit and a focalizing unit. The bone nail has a tube wall and at least one through hole. The tube wall is enclosed to form a receiving space. The at least one through hole extends through the tube wall and communicates with the receiving space. The light source unit includes a light emitter and at least one light transmission tube. The at least one light transmission tube is connected to the light emitter and receives a light therefrom. The at least one light transmission tube is received in the receiving space of the bone nail. Each light transmission tube has a light-outputting end aligned with a respective one of the at least one through hole. The focalizing unit has a light-receiving face facing one of the at least one through hole.
