Specific embodiment
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to embodiment set forth herein；On the contrary, thesing embodiments are provided so that this is practical new
Type will be full and complete, and the design of example embodiment is comprehensively communicated to those skilled in the art.It is identical in figure
Appended drawing reference indicates same or similar structure, thus the detailed description that will omit them.
Referring to Fig. 1 to Fig. 3, the utility model embodiment discloses a kind of pelvis fixture, which is used for
On one spinal operation bed 5.There are two the cross bars 51 being parallel to each other for the spinal operation bed 5 tool, in spinal operation, patient lies prone
On the two cross bars 51, back is exposed to doctor upward.The pelvis fixture of present embodiment includes two supports
1, two arc folded arm 2 of support, band 3 and positioning device 4.
Two supporting brackets 1 are fixedly installed on two cross bars 51 respectively.When patient lies prone is in cross bar 51, the two supporting brackets
For supporting the two sides of the crotch of patient respectively.By Fig. 1 and Fig. 3 it is found that in present embodiment, the structure of two supporting brackets 1 is
Arc support, the degree of bending substantially with crotch's Curve Matching of human body, so as to be preferably supported to patient.This two
A supporting bracket 1 can be movably disposed on cross bar 51 by components such as screw or pins, when supporting bracket 1 is moved to appropriate position
When setting, by itself and the fixed locking of cross bar 51.Supporting bracket 1 can also be permanently fixed to cross bar 51 by the methods of welding, being bonded
On.
Two arc folded arms 2 are hingedly connected to the top of two supporting brackets 1.The two arc folded arms 2 can pass through metal
The components such as hinge or pin shaft are realized hinged between supporting bracket 1.When moving the two arc folded arms 2 with hand, arc can be made
Folded arm 2 is rotated relative to supporting bracket 1.When patient lies prone is after on supporting bracket 1, by rotating the two arc folded arms 2, make two
Arc folded arm 2 is close to each other, can obvolvent in the upside of the crotch of patient.As shown in Figures 1 and 3, band 3 can be with two arcs
The top of shape folded arm 2 is connected, to tighten the crotch of patient.Supporting bracket 1 and arc folded arm can be carbon fiber part, portable construction,
Intensity is higher.In the present embodiment, one end of the band 3 is fixedly connected on one of arc folded arm, the other end with it is another
A arc folded arm is separable.Under discrete state, it will not influence patient and stand up to act.
By above-mentioned supporting bracket 1, arc folded arm 2 and band 3, the crotch of patient can be constrained, by patient
Body steadiness be fixed on spinal operation bed.A locator is thus connected by positioning device 4, and makes locator
It is kept fixed relative to cross bar 51.Locator is kept fixed relative to cross bar 51, is also equivalent to keep solid with the backbone of patient
It is fixed.The locator need not enter the internal of patient, but positioning action directly can be realized in vitro.It avoids in this way
Additional surgical caused by installation positioner operates on the backbone bone of patient, simplifies surgical procedure, shortens operating time, subtracts
The light pain of patient.
The structure of the positioning device 4 is not intended to limit, as long as can be kept fixed locator relative to cross bar 51.It should
Positioning device 4 can be fixedly installed on cross bar 51, can also be set on supporting bracket 1.In the present embodiment, the positioning
Device 4 is fixed on cross bar 51, and positioning device 4 adjustable in this way opens the position on cross bar 51.When positioning device 4 is fixed
It is arranged when on supporting bracket 1, can takes off positioning device 4 from cross bar 51 together during dismantling supporting bracket 1.
Referring to Fig. 1, Fig. 4 and Fig. 5, in the present embodiment, which includes pedestal 41, first connecting rod 42 and
Two connecting rods 43.For pedestal 41 for being fixedly installed on cross bar 51 or supporting bracket 1, which is rotationally connected with pedestal
41, and can be fixed with pedestal 41.As shown in figure 5, in the present embodiment, the top of the pedestal 41 and first connecting rod 42
The fluted disc that bottom is equipped with mutual make-up and engages, the two fluted discs can be attached by fasteners such as bolts.When in use,
Rotary fluted disc first adjusts the angle between first connecting rod 42 and pedestal 41, is then locked two fluted discs using bolt.
Second connecting rod 43 is rotationally connected with the top of first connecting rod 42 and can be fixed relative to the first connecting rod 42.The second connecting rod 43
One end be free end, the free end be used for connecting positioner.
In the present embodiment, the rotational plane at 43 place of the first connecting rod 42 and second connecting rod is vertical, such energy
It is enough that position adjustment is carried out in biggish spatial dimension to locator.
The utility model embodiment also discloses a kind of spinal operation bed 5, and there are two what is be parallel to each other to bow for patient for tool
Sleeping cross bar 51 further includes the pelvis fixture of present embodiment on the spinal operation bed 5.
