In the present embodiment, as shown in Figures 1 and 2, the push-and-pull component 2 includes being respectively arranged on two to inject cylinder 1 just
Two turntables 21 of top and two are connected to the turntable 21 of the same side and inject the swing rod 22 between bar 8, the swing rod
22 lower end is hinged on the upper end for accordingly injecting bar 8, and 22 upper end of swing rod is hinged on the eccentric part of corresponding turntable 21, and two
The sum of height of elemental height difference and piston head 7 between the upper end hinged place of swing rod 22 is equal to the height for injecting 1 inner cavity of cylinder；
Dual-axle motor 23 is equipped between two turntables 21, two output shafts of the dual-axle motor 23 are connected respectively to two turntables
At 21 center, is injected described in two and be connected with support transverse slat 24 between cylinder 1, be fixed with and be supported on the support transverse slat 24
The vertical support plate 25 of 23 bottom of dual-axle motor.In application, starting dual-axle motor 23 rotates, it can 21 turns of the turntable of synchronous drive two
Dynamic, then the hinged end of swing rod 22 and turntable 21 is injected bar 8 by the pulling of swing rod 22 and is moved up and down around the center rotating of turntable 21,
Piston head 7 is able to achieve in the suction injected in cylinder 1 and injects movement, and the suction of two piston heads 7 and injects movement and hands over
Mistake carries out, and meets design requirement.
In the present embodiment, as shown in fig. 7, the output end of the flushing pipe 10 penetrates drainage tube 20 by 20 side of drainage tube
Inside simultaneously extends along drainage tube 20 to its output end, and the outlet of the drainage tube 20 is set to its output end side, the drainage tube
Sealing rubber ring 50 is equipped at the position passed through on 20 for flushing pipe 10.The output end of flushing pipe 10 is set in drainage tube 20
Portion can realize the fixation to flushing pipe 10 while drainage tube 20 is fixed at wounds, and operation is more convenient, and answers
It is preferable with effect.
The specific action principle of the above-mentioned dedicated Minitype negative pressure adjustable drainage device of micro- hand and foot surgery are as follows:
When needing to drain patient, the output end of drainage tube 20 is fixed at the surface of a wound of patient, flushing pipe 10
Output end is fixed therewith, after clip 40 is removed from flushing pipe 10, cleaning solution is injected into flushing pipe 10, cleaning solution is along flushing
Pipe 10 flows out, and operation can be rinsed to the surface of a wound, can stop flushing operation with the input terminal that clip 40 clamps flushing pipe 10；
Start dual-axle motor 23, two turntables 21 can directly be driven to rotate, the hinged place of 22 upper end of swing rod and turntable 21 around
The central point of turntable 21 rotates, and the upper end of a swing rod 22 rotates from the bottom to top at the center of turntable 21, and swing rod 22 pulls phase
Bar 8 should be injected to move up, respective pistons head 7 is driven to move up, so that shape in cylinder 1 is injected in 7 lower section of respective pistons head
At negative pressure, because the restriction of check valve 26 gas in exhaust pipe 5 can only be mobile to the external world in cylinder 1 from injecting, and exhaust tube 3
Interior check valve 1 limits gas and can only move from liquid storage container 30 to injecting in cylinder 1, then accordingly injects cylinder 1 in negative pressure
The gas in liquid storage container 30 is aspirated under state, so that negative pressure is generated in liquid storage container 30, thus by producing in drainage tube 20
Light soy sauce suction is aspirated into drainage tube 20 to drain at wounds, and enters along liquid storage container 30 along drainage tube 20；
Meanwhile the upper end of another swing rod 22 from top to bottom rotates at the center of turntable 21, swing rod 22, which pushes, accordingly injects bar 8 downwards
It is mobile, drive respective pistons head 7 to move down, so that the gas pressure intensity of 7 lower section of piston head injected in cylinder 1 gradually increases
Greatly, under the orientation of check valve 1 and check valve 26, so that the gas accordingly injected in cylinder 1 is discharged from exhaust pipe 5,
When piston head 7 is moved to the interior bottom for injecting cylinder 1, the gas injected in cylinder 1 is completely exhausted out, to inject under cylinder 1
Primary suction action provides convenient；After the output shaft of dual-axle motor 23 turns over half-turn, the moving direction of two swing rods 22 is exchanged,
So that the cylinder 1 of injecting for generating negative pressure before stops generating negative pressure, and the cylinder 1 of injecting for not generating negative pressure before generates negative pressure,
And so on, then two inject cylinder 1 and can be alternately produced negative pressure, when can reduce the negative pressure generation of negative pressure generating device and resting
Between, to be conducive to improve pumping efficiency；
It drains in application process, rotation inner sleeve 12 can be such that bar shaped port 13 is connected to a small through hole 14, when piston head 7
After being moved upward to the 14 place height of small through hole, because ambient atmos can be along 12 inner cavity of inner sleeve, bar shaped port 13 and this is small
Through-hole 14, which enters, injects in cylinder 1, then in the subsequent uphill process of piston head 7, injects in cylinder 1 and no longer generate negative pressure, from
And the suction strength in liquid storage container 30 no longer increases.By rotating inner sleeve 12, different small through hole 14 and bar shaped can be made logical
Mouthfuls 13 are connected to, and corresponding suction strength is different, i.e., the suction generated to drainage tube 20 is different, then suction is controllable, are not easy pair
Tissue causes to damage, and safety in utilization is preferable.
As shown in the above, suction of the present invention is controllable, is not easy to cause to damage to tissue, and safety in utilization is preferable, and
Pumping efficiency is higher.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen in scope of the presently claimed invention.
