Description
Technical field
The present invention relates to technical field of medical instruments, particularly relates to a kind of operation lithotomy position leg support.
Background technology
Leg support be lithotomy position operation in important medicine equipment, traditional leg support be to being supported at patient's Tui popliteal, it is this
Leg support easily causes patient leg blood circulation disorder because Area of bearing is small, and can avoid this to the leg support of leg support
Kind secondary injury, therefore calf support leg support is increasingly popularized.
The operation table such as leg support annex is used by being fixed on the side rail of operation table both sides, for the ease of making
With operation bedside rail size is typically provided with following several specifications：Section 30*10mm, 30*8mm, 25*10mm, 25*8mm, it is existing
The fixed form for having leg support fixing device is two kinds：First, adjustable screw rod is fixed up and down, this fixed form can only be to longitudinal direction
Fastened, can not be to laterally fastening, therefore fixation is insecure, once the meeting that comes off is huge to patient's generation in surgical procedure
Injury；Second, two-way adjusting screw is fixed, though this mode can fasten to transverse and longitudinal simultaneously, complex operation, tune need to be coordinated
Both direction is saved, and the pressure area that screw rod is fixed is small, it is fixed unstable, and easily opposite side rail causes irreversible damage.
The activity of existing lithotomy position leg support and the cooperation that lock mode is eccentric shaft and eccentric push rod, are rotated by eccentric wheel
Impulse stroke, hemisphere bearing activity or locking are opened by eccentric push rod top by pressure, but in existing eccentric shaft structure
Push rod is simple integral type column, and this design has two：First, to the tangential force of push rod when eccentric wheel rotates
Can be by push rod itself rigidity and the counteracted by pressure of outside disc spring screw, therefore push rod is extremely easily damaged；Two be due to that push rod is
Rigid member, the impulse stroke of eccentric wheel is completely converted into the movement travel of push rod, so if not regulating push rod using preceding
Position, the rotation of handle is very difficult, and is easily damaged latch-up structure.
Leg support in leg support needs to be adjusted according to different surgery situations, therefore it is ten that the multiple degrees of freedom of leg support, which rotates,
Point it is necessary, but the locking that rotates of multiple degrees of freedom is also cumbersome, it is necessary to more each direction of motion is locked respectively,
It is excessively complicated in operation technique, it is therefore desirable to a kind of to make the regulation of leg support multiple degrees of freedom and be easy to the locking knot of lock operation
Structure.
Leg support is succinctly easy to operate not only for attractive in appearance as a kind of operation medicine equipment, even more to surgical procedure
A kind of power-assisted, the existing most lever for adjusting oil of leg support is more, and complex operation, rivet or adjusting rod are exposed, very influences to perform the operation
Journey.
