There is threaded compression bar 9,5 surface of arc rubber mat is additionally provided with several ventilative through holes 8, and the ventilative through hole 8 is in Curved Continuous
It is curved, and 8 other end of ventilative through hole extends through 5 bottom of arc rubber mat.
When in use, multiple push-pull rods 2 on elastic clamp ring 1 can distinguish activity adjustment to different positions, pass through work
The effect of dynamic clamping element 10 and silica gel gib head 3, wound position is fixed up, thus facilitate going on smoothly for operation, and
And active clamping piece 10 and silica gel gib head 3 are applied in combination, and convenient for adjusting clamping dynamics, secondary damage will not be caused to operative site
Wound.
Under normal condition, the self gravity of arc rubber mat 5, arc rubber mat 5 is in state vertically downward, concrete operations
When, the terminal position of rotation twist collar 4 to push-pull rod 2, later by pressing threaded compression bar 9, so that inside sealed passage 7
Gas compressed, under gas pressure so that inflation expulsion bladder 6 inside air pressure increase, thus inflate 6 volume of expulsion bladder increase
Greatly, squeezing action is generated to arc rubber mat 5, so that arc rubber mat 5 is close to the position of silica gel gib head 3, thus by operation wound oral area
Position is clamped in the position of silica gel gib head 3 and arc rubber mat 5, convenient for the progress of subsequent procedures, and when unclamping, need to only draw high screw thread
Constrictor 9, so that inflation 6 air pressure inside of expulsion bladder reduces, so that under the effect of gravity, arc rubber mat 5 is automatically reset to normally
State.
5 surface of arc rubber mat is provided with several segmental arcs 601, ventilative through hole 8 be located at adjacent segmental arc 601 it
Between, and segmental arc 601 is internally provided with several layers bending foam-rubber cushion 602, and when arc rubber mat 5 and operative site contact
It waits, surface is contacted by multiple arcs section 601 and operative site, and the ventilative through hole 8 between multiple arcs section 601 plays
Ventilative protective effect, since long-term surgery operates, clamping operative site may result in local damage, pass through ventilative through hole 8
It realizes the ventilated of skin part, plays a good protective effect.
Further, when arc rubber mat 5 and operative site contact, the buffering of foam-rubber cushion 602 is bent by multilayer
Effect further functions as the effect of buffer protection so that with arc rubber mat 5 excessive contact will not occur for the limbs of operative site,
While realizing that arc rubber mat 5 slowly contacts operative site, the pressure that arc rubber mat 5 generates operative site is further decreased
Compel effect, so that operative site contact is more comfortable.
