PREFERRED EMBODIMENTS

(5) The following embodiments are not for limiting the use, but for presenting variety of the invention.

Example 1

(6) Please refer to FIGS. 1-3. As shown in FIG. 1, the invention provides a guide for surgical purpose (10), comprising: a long column body (20), being in a hollow shape, an upper side thereof having a semi-cylinder (21), in which at one end thereof and proximate to a hand-held part is provided with thread (211), a bottom side thereof having a cuboid (22), and an inside thereof being provided with an elongated slot (23), in which an interior of the semi-cylinder is in communication with an interior of the cuboid; a wing-shaped part (30), 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 (40), 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 (50), as shown in FIG. 2, which is in a round rod shape and formed in sequence by connection of a tail rod handle (51), a threaded rod (53), and a rod body (52) for expanding, and is disposed in the elongated slot, for expanding and opening a surgical incision of tissues.

(7) FIG. 3 is a schematic diagram in combination of a guide for surgical purpose according to the invention, in which the replaceable expander (50) is disposed in the elongated slot (23) of the cuboid (22) of the long column body (20). In the practical operation, the thread rod (53) of the replaceable expander (50) is mutually engaged with the semi-cylinder (21) on the upper side of the long column body (20) at a place of the thread (211) provided in an external surface proximate to the wing-shaped part (30), i.e. proximate to the hand-help part, thereby forming the guide for surgical purpose (10). The thread (211) may be rotated to extend the rod body (52) into the tissues of the hand for expanding. After expansion, a knife (not shown in the drawing) may be utilized to replace the expander (50) and is forwarded ahead along the elongated slot for cutting the portion of the wrist transverse ligament to be cut open, and via the limiting piece (40), a doctor is informed that the cut position has been arrived so as to avoid cutting further the tissues not intended to be cut. During cutting, a picture-taking element (not shown in the drawing) may be provided at a proper place of the elongated slot for taking pictures, while an externally connected picture-displaying element may be provided for facilitating the proceeding of the surgery. The expander may be replaced with different dimensions in a stepwise manner, such as in an order from 5 mm, 6 mm to 7 mm, via one side of the cuboid proximate to the wing-shaped part and inside the elongated slot.

(8) While the invention has been described and exemplified in sufficient detail for those skilled in this art to make and use it, various alternatives, modifications, and improvements should be apparent without departing from the spirit and scope of the invention.
