DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(10) Referring to the drawings, and initially to FIGS. 1, 2 and 3, a medical instrument holding or supporting apparatus in accordance with the present invention comprises a supporting device or mechanism 1 including a stand or base 10 for being disposed or attached or mounted or secured on a supporting surface or ground or the like, and including a supporting arm 20 having a lower or bottom portion 21 pivotally or rotatably attached or mounted or secured on the upper portion 11 of the base 10 with a pivot joint or member or device 22 and arranged for allowing the supporting arm 20 to be pivoted or rotated relative to the base 10 freely around a Z-axis or longitudinal axis of the base 10 for 360 degrees, and arranged for allowing the supporting arm 20 to be pivoted or rotated relative to the pivot device 22.

(11) The supporting arm 20 further includes another pivot device or joint or member 23 formed or provided or disposed or engaged on the upper portion 24 of the supporting arm 20 and arranged to be pivoted or rotated relative to the supporting arm 20, the pivot member 23 includes a sleeve or cylindrical or tubular element or barrel or housing 25 provided or attached or extended forwardly therefrom and arranged or extended along the X-axis, for example. The housing 25 includes a bore or chamber 26 formed therein, and includes a longitudinal guiding flange or rib or member 27 extended into the chamber 26 of the housing 25 (FIGS. 2, 7) and parallel to the housing 25, and includes a number of orifices or screw holes 28 formed or provided in the outer or free end portion 29 thereof, and arranged equally spaced from each other.

(12) A follower or sliding member or shaft 30 is engageable with or into the chamber 26 of the housing 25 and movable or adjustable relative to the housing 25 and movable or slidable into and out of the chamber 26 of the housing 25, and includes a longitudinal guiding groove or channel or element 31 formed in the outer peripheral portion thereof for slidably receiving or engaging with the longitudinal guiding member 27 of the housing 25 and for guiding or limiting the shaft 30 to slide or move relative to or along the housing 25 and for preventing the shaft 30 from being pivoted or rotated relative to the housing 25, and includes a positioning or retaining or anchoring member 32, such as an outer thread 32 formed or provided thereon, and includes a holding or grasping or gripping mechanism 33 formed or provided or disposed on the outer or free end portion 34 of the shaft 30 and provided for holding and grasping a treating or medical instrument (not illustrated).

(13) For example, the treating or medical instrument may be selected from a rigidoscope, laparoscope, endoscope, trocar, treating instrument, or the other medical instruments. However, the treating or medical instrument is typical and is not related to the present invention and will not be described in further details. The treating or medical instrument holding or grasping or gripping mechanism 33 is thus formed or provided or disposed on or extended from the outer or free end portion 34 of the shaft 30 and moved in concert with the shaft 30 relative to the housing 25, and arranged for allowing the shaft 30 and the gripping mechanism 33 and thus the treating or medical instrument to be moved or adjusted toward or away from the housing 25.

(14) The medical instrument holding or supporting apparatus in accordance with the present invention further comprises a latching or anchoring or retaining or positioning or locking ring or device 40 including a chamber or bore 41 formed therein for slidably receiving or engaging with the shaft 30 and for allowing the locking device 40 to be slidably attached or engaged onto the shaft 30, and the locking device 40 is selectively locked or secured or fastened to the housing 25 with latches or bolts or screws or fasteners 42 or the like, in which, as shown in FIGS. 1-6, the fasteners 42 are threaded or engaged with the screw holes 28 that are formed or provided in the outer or free end portion 29 of the housing 25. The locking device 40 further includes another anchoring or retaining or positioning member 43, such as an inner thread 43 formed or provided therein for selectively engaging with the outer thread 32 of the shaft 30 and for selectively latching or anchoring or retaining or locking or positioning or securing the shaft 30 and the housing 25 together with the locking device 40.

(15) In operation, the longitudinal guiding member 27 of the housing 25 is slidably received or engaged in the longitudinal guiding channel or element 31 of the shaft 30 for guiding or limiting the shaft 30 only to slide or move relative to or along the housing 25 and for preventing the shaft 30 from being pivoted or rotated relative to the housing 25, and thus for allowing the shaft 30 and the gripping mechanism 33 and thus the treating or medical instrument to be moved or adjusted toward or away from the housing 25 selectively (FIGS. 3, 4). After the housing 25 and the shaft 30 have been adjusted relative to each other to the required location or position, as shown in FIGS. 3-6, the locking device 40 may be moved or rotated or adjusted relative to the shaft 30 and may be locked or secured or fastened to the housing 25 with the fasteners 42 or the like for preventing the shaft 30 from being pivoted or rotated and moved relative to the housing 25.

(16) It is to be noted that the adjustable or sliding engagement or attachment mechanism or structure or configuration of the shaft 30 relative to the housing 25 allows the gripping mechanism 33 and thus the treating or medical instrument to be supported at different location or position for conducting different medical surgery or medical operation. Alternatively, as shown in FIGS. 8-11, the shaft 300 may be provided or attached or extended forwardly from the pivot member 230 of the supporting arm 20, and the housing 250 may include the holding or grasping or gripping mechanism 330 formed or provided or disposed thereon for holding and grasping the treating or medical instrument (not illustrated) and may be movably or adjustably or slidably attached or engaged onto the shaft 300, and may be locked or secured or fastened to the shaft 300 with the locking device 40.

(17) Accordingly, the medical instrument holding apparatus in accordance with the present invention includes an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be adjusted to different length for conducting different medical surgery or medical operation.

(18) Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
