Topic.
Chinese patent CN201620036266 discloses a kind of Multifunctional surgical expander, solves to a certain extent
The deficiencies in the prior art, but it still has the single problem of dimension, it is often necessary to cooperated using multiple groups expander
It being required using can be only achieved operation, inconvenience is still had in practical.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of multi-direction surgical operation expanders, can consolidate, just
The prompt tissue of expansion in different directions and appear visual area, goes on smoothly creation convenience for surgical operation.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of multi-direction surgical operation expander includes one group of horizontal-extending stull in structure and is arranged in this stull two
The bayonet at end is provided with one group of screw hole in the middle section of the stull, and one group is provided through inside this screw hole and is slided with its screw thread
The screw rod of connection, this screw rod lower end are connected with one group of downward curved roof in arc top.
As a kind of optimal technical scheme of the utility model, the screw rod lower end is equipped with a connected ball, the arc
Cover top surface is correspondingly provided with one group of spherical groove, and the connected ball rotation is socketed in inside of spherical groove.
As a kind of optimal technical scheme of the utility model, the stull uses straight transverse sheet.
As a kind of optimal technical scheme of the utility model, the stull uses the elasticity extended in sine curve sample horizontal
Piece.
As a kind of optimal technical scheme of the utility model, the bayonet is the U-clamp plate of outward opening.
As a kind of optimal technical scheme of the utility model, the edge of the U-clamp plate curls into circular arc crimping.
As a kind of optimal technical scheme of the utility model, the upper edge of the curved roof curls into circular arc volume
Side.
The beneficial effects of adopting the technical scheme are that can consolidate, easily expand in different directions
Visual area is organized and appeared, goes on smoothly creation convenience for surgical operation.
The utility model is provided with one group of vertical and height-adjustable screw rod in the middle section of stull, and screw rod lower end is connected with one
Group curved roof, in this way, while stull struts tissue in the horizontal direction, curved roof being capable of expansion group along the vertical direction
It knits, also, the height of curved roof can also be conveniently adjusted by adjusting screw rod, adapt to the various tissues of operative site
Environment.
Further, the utility model is equipped with a connected ball in screw rod lower end, and curved roof upper surface is correspondingly provided with
One group of spherical groove, connected ball rotation is socketed in inside of spherical groove, in this way, screwing screw rod so as to adjust the height of curved roof
When, it can be ensured that curved roof does not rotate, to avoid possible tissue injury.Especially, the group of surgical field of view
Knitting bottom end may not be horizontal, the inclination of different directions may be presented, " connected ball-spherical groove " of the utility model just adapts to
The inclination of adaptability can occur according to the Tissue distribution of surgical field of view bottom naturally for this Tissue distribution complicated and changeable,
With splendid practical function.
The stull of the utility model uses the elastic transverse sheet extended in sine curve sample, special with certain flexible support
Property, injury is reduced to tissue.In addition, the U-clamp plate of the utility model and the edge of curved roof curl into circular arc crimping,
A possibility that tissue injury, is also preferably minimized by such detailed design.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one specific embodiment of the utility model.
Fig. 2 is the structural schematic diagram of the utility model another embodiment.
Fig. 3 is the partial enlargement diagram of the utility model " connected ball-spherical groove " structure.
In figure: stull 1, bayonet 2, screw hole 3, screw rod 4, connected ball 5, spherical groove 6, curved roof 7, circular arc crimping 10.
Specific embodiment
Embodiment 1
Referring to attached drawing 1,3, in the structure of one specific embodiment of the utility model include one group of horizontal-extending stull 1 and
The bayonet 2 at this 1 both ends of stull is set, and bayonet 2 is the U-clamp plate of outward opening, and the edge of U-clamp plate curls into circular arc volume
Side 10, stull 1 use straight transverse sheet, the middle section of stull 1 are provided with one group of screw hole 3, is provided through one group inside this screw hole 3
The screw rod 4 being slidably connected with its screw thread, 4 lower end of screw rod are equipped with a connected ball 5, are arranged on the curved roof 7 of 4 lower end of screw rod
Surface is correspondingly provided with one group of spherical groove 6, and the rotation of connected ball 5 is socketed in spherical groove 6.
Referring to attached drawing, the working principle of the utility model is: the utility model is provided with one group in the middle section of stull 1 and hangs down
Straight and height-adjustable screw rod 4,4 lower end of screw rod is connected with one group of curved roof 7, in this way, strutting group in the horizontal direction in stull
