The specific embodiment
By the following examples and in conjunction with the accompanying drawings structure of the present invention is described in detail.
As shown in Figure 1, the present invention includes lower carriage assembly 10, entablature assembly 30, recliner assembly 50 and intervention arrangement for guiding 70.
Shown in Fig. 2～4, lower carriage assembly 10 of the present invention comprises that one has the base 11 of constant weight, and the bottom of base 11 is provided with four rolling 12, in order to support and to make things convenient for push-and-pull to move entire equipment.The fixedly connected standpipe 13 at base 11 tops is provided with an outer housing 14 of fixedlying connected with base 11 in the outside of standpipe 13.Middle part and outer housing 14 topmosts at standpipe 13 are provided with a fairlead 15,16 respectively, plug arm 17 in two fairleads 15,16.One side of last arm 17 is provided with tooth bar 18.In the outer housing 14 on standpipe 13 tops, be provided with one with tooth bar 18 meshed gears 19, with the gear 19 coaxial sprocket wheels 20 that are provided with, another sprocket wheel 21 is set in the bottom of standpipe 13, on two sprocket wheels 20,21 around a chain 22, a fixedly connected counterweight 23 on the side chain bar 22 outside, inboard chain 22 passes the opposite side of counterweight 23.The setting principle of counterweight 23 is: upward arm 17 reaches weight and the counterweight 23 formation dynamic equilibrium with upper-part, like this, if there is external force upwards to promote when going up arm 17 or pressing arm 17 downwards, tooth bar 18 on the last arm 17 just can driven gear 19, sprocket wheel 20,21 and chain 22 rotate, counterweight 23 is moved up and down, reach the dynamic equilibrium of another location; This moment since the power that the operator uses only for overcoming the frictional force between gear 19 and the tooth bar 18, so the operator be promote or under press arm 17 all can be very brisk laborsaving.For preventing to cause mobilely touching arm 17 unintentionally, a handle 24 that passes outer housing 14 is set, after last arm 17 and lower carriage assembly 10 are adjusted, on outer housing 14 to make things convenient for locking positioning.
As Fig. 5, shown in Figure 6, entablature assembly 30 of the present invention comprises that a connecting column 31, is arranged on the T junction 33 that connecting column 31 intermediary covers of wedge 32, are arranged on cover of wedge 32 outsides, and cover of wedge 32 is fixedlyed connected by a plurality of screws with T junction 33 and is integral.Two voussoirs 34,35 penetrate cover of wedge 32 from the both sides of connecting column 31 respectively, and two baffle plates 36,37 are fixed on the connecting column 31 by a plurality of screws from two ends respectively.One stop nut 38 is screwed onto in the center screw of baffle plate 37, the end of stop nut 38 withstands on the voussoir 35, one screw rod 40 with rotary handle 39 is connected in the center screw of two voussoirs 34,35, and one of the center screw of two voussoirs 34,35 is left-handed, a dextrorotation, when therefore corresponding with the two screw rod 40 rotated, two voussoirs 34,35 can relative motion, and then locking or unclamp cover of wedge 32 and be fixed on T junction 33 on the cover of wedge 32.Fixedly connected with last arm 17 tops with a nylon jacket 42 by a locking nut commonly used 41 in connecting column 31 bottoms.
As Fig. 5, shown in Figure 7, in T shape cover 33, wear a crossbeam 43, the two ends of T shape cover 42 also adopt locking nut commonly used to fixedly connected with crossbeam 43 with nylon jacket.The end that entablature assembly 30 is connected with recliner 50 is provided with an elbow 44, the transition axis 46 that is connected by key and keyway 45 in elbow 44, one adjusts cover 47 by being threaded on the transition axis 46, outside at transition axis 46 overlaps 48 by one group of three lobe, an end of 47 is overlapped in connecting bend 44 and adjustment simultaneously, crossbeam 43 end internal fixation connect a swivel nut 49, and swivel nut 49 is plugged in crossbeam 43 and adjusts in the cover 47, and rotating beam 43 can be fixed on swivel nut 49 on the transition axis 46.
Shown in Fig. 8～11, recliner assembly 50 of the present invention comprises a housing 51, at housing 51 1 ends one connecting axle 52 is set, the axle center of relative connecting axle 52, the one upper and lower ball seat that links into an integrated entity 53,54 is set in housing 51, the bulb of one ball journal 55 is set in upper and lower ball seat 53,54, at the top of housing 51 and sidepiece one depress spiro rod 58 and the thruster screw rod 59 that drives by fine-tuning nut 56,57 is set respectively, the bottom of depress spiro rod 58 and thruster screw rod 59 is provided with a swing set 60,61 that is connected ball journal 55 respectively.Connect a transition axis 62 in the end of ball journal 55, connect a handwheel 63 and drive a rebound 64 that rotates by handwheel 63 on transition axis 62, rebound 64 connects by a rotary handle gets involved arrangement for guiding 70.Recliner 50 is to be used to regulate the deflection angle of getting involved arrangement for guiding 70 and inserting needle direction, it is a upper and lower, left and right swing with bulb that adjusting fine-tuning nut 56,57 can make ball journal 55 respectively, and adjusting handle 63 can make intervention arrangement for guiding 70 move axially along ball journal 55.
As Fig. 8, shown in Figure 12, intervention arrangement for guiding 70 of the present invention comprises two hinged outer pin cards 71,72, and pin card 73,74 in two is set in the pin card 71,72 outside described two, wears puncture needle 75 in the pin card 73,74 in two.Wherein the outer pin card 71 of a side and interior pin card 73 are integral with fixedlying connected with rebound 64, the outer pin card 72 of opposite side can be opened by external mutually pin card 71, to put into another pin card 74 and puncture needle 75, close after the outer pin card 72, can two outer pin cards 71,72 be fixed together by a screw 76, the two fixed degree of tightness depends on puncture needle 75, and it can be slided in interior pin card 71,72 under the effect of external force.
The present invention adjusts the position revolute throughout and moving sets all adopts nonmetallic materials, for example: fairlead 15,16 adopts polytetrafluoroethylmaterial material can reduce the coefficient of friction of moving sets greatly, make full use of the characteristics of its self-lubricating, make each movable secondary activity freely, light, volume is lighter and handier.For example cover of wedge 32 adopts phenolic resin material again, can improve the coefficient of friction of revolute pair, and it is more firm that crossbeam 43 is adjusted back locking.
When the present invention uses, can promote base 11 and move any position, can arm 17 upper and lower moving will be gone up by rotary handle 24, can rotate moving beam 43 by rotary handle 39, by rotating the direction that fine-tuning nut 56,57 and handwheel 63 can be regulated puncture needle, to aim at patient's lesions position; In case complete operation, the doctor just can import predetermined lesions position with puncture needle easily exactly.
