Description

Stable and the adjusting device of endoscope operation cavity

Technical field

The present invention relates to the surgical operation assistive device, particularly stable the and adjusting device of endoscopic surgery space chamber.

Background technology

Some little otch endoscopic surgeries as the thyroid endoscopic surgery, need be set up operation cavity (working-space) in the body.The foundation of this before this operation chamber is to lift formation by manually handing through apparatus, and its defective is: chamber size and shape instability, cavity space distortion be difficulty, and this causes operating difficulty to increase, and time-consuming.

Set up described operation cavity, though have some for using means, hang in conjunction with drag hook with bracing frame as adopting general anesthesia, it uses operation inconvenience, and the foundation of chamber and space deformation adjusting difficulty are bigger, are difficult to smooth and easy the carrying out of adaptation operation.

Summary of the invention

The present invention will solve present endoscope operation cavity foundation and regulate difficulty, the chamber instability of building, and the problem that causes operating difficulty to increase provides stablizing and adjusting device of a kind of endoscope operation cavity of the present invention for this reason; The operation cavity stability of setting up with this device is high, and cavity space is easy to adjust, helps operation and carries out smoothly.

For addressing the above problem, its special character of the technical solution used in the present invention is: be provided with can with the fixed supporting base of operation table, be associated with variable angle pole on the supporting base, described variable angle pole upper end is associated with cross bar, be set with on the cross bar and can move and localized movable hanger seat relative to this cross bar, movable hanger seat lower end is associated with movable hanger, is associated with drag hook on the movable hanger.

Described supporting base can be made of extension bar and ball seat that the upper end joined thereof, and described variable angle pole is made of the steel ball that the montant and the T shape bar lower end of T shape bar and interior cover thereof joined, and steel ball is positioned at the ball seat of described supporting base, so forms universal joint.

Be set with on the described cross bar and can move and localized movable hanger seat can be meant relative to cross bar: be fixed with block set on the cross bar, being set with relatively on the block set, block set move also localized described movable hanger seat.Adding this block set on the cross bar is to make movable hanger location more firm.

Be set with on the described cross bar can relative to cross bar move and localized movable hanger seat can also be meant: be fixed with block set on the cross bar, movable hanger seat is made of fixing head itself and the ball seat that joined, the fixing head back side is associated with fixed mount, fixed mount is placed on described block set, between fixed mount and the block set through set hold-down screw positioning and fixing.Set up described fixed mount and be to make upper and lower adjustable the moving of movable hanger seat energy relative fixed frame.

Described movable hanger seat lower end is associated with movable hanger can be meant that movable hanger is made of connecting plate and steel ball that the upper end joined thereof, and steel ball places the ball seat of described movable hanger seat, so forms another universal joint.

Be associated with drag hook on the described movable hanger and can be finger retractor have rise to the bait, hook and groove down, offer groove and through hole on the connecting plate, rising to the bait of drag hook is positioned at the groove of connecting plate, the through hole of movable hanger bottom is corresponding to the groove of drag hook, is equipped with the chevron bolt in the through hole and is combined with hold-down nut on it.So, drag hook and movable hanger seat link, and can adjustablely move, locate relative to movable hanger is upper and lower.

The fixing head back side of described movable hanger seat is associated with fixed mount and can be meant: the fixing head lower end is provided with button, the riser bottom of fixed mount is provided with catching groove, button is embedded at this catching groove movably, the riser upper end of described fixing head and fixed mount has the horizontal folding section of prolonging, be equipped with adjusting screw(rod) between this two foldings section of prolonging, thus can upper and lower adjustable the moving of realization activity hanger seat.

Steel ball described in the present invention is preferably stainless steel ball.

Drag hook described in the present invention can have the plurality of specifications size, hook places in the operative incision under it, draw and set up described operation chamber on adjustable, adjust tentering degree and upper and lower angle of fall degree and the left and right sides steering angle of sticking up of drag hook on the drag hook, can change and operate cavity space size and space deformed state.

The present invention is owing to be provided with and can be associated with variable angle pole on it with the fixed supporting base of operation table, variable angle pole upper end is associated with cross bar, be set with on the cross bar and can move and localized movable hanger seat relative to described cross bar, movable hanger seat lower end is associated with movable hanger, be associated with drag hook on the movable hanger, so the present invention not only can set up the endoscope operation cavity of form stable easily, and the interior space size and shape of the chamber of building is easy to adjust, so not only can conveniently perform the operation and carry out, and can overcome manually to lift and build time-consuming defective due to the intonation chamber.
