DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for fixing a brain spatula with a base, which can safely and easily perform stable and appropriate brain surgery.

[0002]

BACKGROUND OF THE INVENTION The present inventors have already inconvenient for performing surgery and holds the like holding bracket to the skull base head or incision of a subject fitted with a brain spatula and surgical instrument holder, irrational A brain spatula fixing device with a base has already been invented in order to eliminate the drawbacks such as difficulty and fatigue due to lack of support of the operator's hand during surgery, as well as the nature and danger.

[0003] That is, a semi-arc-shaped universal holder solid frame in which a height-adjustable base, a brain spatula and a universal holder for holding a surgical instrument holder and a surgical instrument holding cylinder are detachably mounted. This is a brain spatula fixing device with a base, which is formed by fitting both ends of a cranial fixing frame having a semicircular shape to both ends thereof so as to be mounted substantially horizontally.

[0004]

The prior art universal retainer fixing frame is fixed to the skull fixing frame in a substantially horizontal state. Therefore, when the skull fixing frame body is moved in an arc, the universal retainer fixing frame cannot hold the horizontal state. Therefore, in order to safely and easily perform stable and appropriate surgery using this, there are naturally restrictions on the surgical site of the subject's head, and even if appropriate surgery can not be performed or even if it can be performed Surgery is very difficult and requires a lot of trouble, and the operation time is inevitably prolonged, and disadvantages such as fatigue of the operator's hand are inevitable. SUMMARY OF THE INVENTION An object of the present invention is to stably and appropriately perform an operation on any surgical site of the subject's head in a simple manner and at the same time ensure a comfortable and easy operation for the operator.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and the gist of the present invention is that a fixed member is provided on a bed-side rigid holding member. A semi-arc shaped skull fixing frame is fixed by a fixing screw so that it can move left and right arcs,
A semi-arc-shaped universal holder fixed frame with a removable spatula for holding a brain spatula and a surgical instrument holder as well as a surgical instrument holding cylinder is detachably attached to both ends of a semi-arc shaped horseshoe-shaped fixed frame rod. And a base and spatula fixing device with a base, wherein both ends are fitted and mounted substantially horizontally, and the fixed frame rod is fixed to a holding member by screwing a central portion at a lower portion thereof. Next, embodiments of the present invention will be described in detail with reference to the drawings.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a rigidly connected main body holder 4 is provided on a bed 3 side.
Of the skull fixing frame 1 having a semicircular arc shape and having the fixing pin 2 is fixed to the holding member 5 by a fixing screw 6 so as to be able to move right and left in an arc. In addition, the height-adjustable platform 13, brain spatula 1
4 and a universal holder 17 for holding a surgical instrument holder, a semicircular universal holder fixing frame 10 detachably mounted with a surgical instrument holding cylinder 16 and the like, and a semicircular horseshoe-shaped fixing frame rod 7. The two ends are fitted in a substantially horizontal manner by fitting the two ends. The fixed frame rod 7 is fixed to the holding member 5 by screwing the lower central portion thereof integrally. Note 8 supporting lifting unit, the fixing screw member 9, 11 designates a base portion, 12 struts, 15 freely cage 18 is incision.

[0007]

According to the present invention, the universal retainer fixing frame is always kept horizontal in correspondence with the head operation site of the subject, and a stable and appropriate operation can be easily performed on any operation site of the subject. . And the operator's fatigue can be remarkably reduced.
