The specific embodiment

The collapsible anoscope of handle of the present invention comprises inspection lens barrel 2, and inspection lens barrel 2 is the big increasers in the little rear end of front end; In the inspection lens barrel 2 mirror core 1 is installed; The front end of mirror core 1 is a bulb, and bulb is positioned at outside the inspection lens barrel 2, and the rear end of inspection lens barrel 2 is provided with adapter sleeve 4; Locking ring 3 is installed in the periphery activity of adapter sleeve 4, and locking ring 3 adapter sleeve 4 relatively rotates.The length of locking ring 3 is greater than the length of adapter sleeve 4, so that first handle 11 when launching with second handle 12, can snap in location in the locking ring 3.As shown in Figure 1; Be that axis symmetry is installed first handle 11 and second handle 12 with pull bar 13 on the adapter sleeve 4; The front end of first handle 11 and second handle 12 is hinged with adapter sleeve 4 respectively; First handle 11 can be hinged through hinge and adapter sleeve 4 with second handle 12, also can be hinged through other existing articulated structures and adapter sleeve 4.Offer first locating slot 5 and second locating slot 6 on the locking ring 3, the both sides that are positioned at first locating slot 5 on the adapter sleeve 4 respectively are provided with one first locating piece 7, and the both sides that are positioned at second locating slot 6 on the adapter sleeve 4 respectively are provided with one second locating piece 8; After first handle 11 and second handle 12 launch; First handle 11 snaps in first locating slot 5; Second handle 12 snaps in second locating slot 6; After first handle 11 launched with second handle 12, first locating piece 7 played the role of positioning with 8 pairs of first handles of second locating piece 11 and second handle 12, prevented that first handle 11 from overturning to close up with second handle 12 to reset.

In first handle 11 and the second handle 12 identical handle positioner is installed respectively; The concrete structure of handle positioner is following: offer first installation cavity 19 on the rear inside wall of first handle 11; In first installation cavity 19 nut 15 and connecting rod 18 are installed, the rear end of connecting rod 18 is threaded with nut 15; Offer second installation cavity 30 and crank-guide way 20 in the first handle 11; The two ends of crank-guide way 20 communicate with first installation cavity 19 and second installation cavity 30 respectively; In second installation cavity 30 spacing block set 21 is installed, the width of spacing block set 21 is installed first tooth bar 31 and second tooth bar 32 greater than the width of connecting rod 18 on the spacing block set 21; The front end of connecting rod 18 passes crank-guide way 20 and is connected with spacing block set 21; Offer the first swinging block groove 33 and the second swinging block groove 34 on the left and right sides sidewall of first handle 11 respectively; Be axis symmetry installation first gear 38 and second gear 39 with spacing block set 21 in second installation cavity 30;

First gear

38 and 31 engagements of first tooth bar,

second gear

39 and 32 engagements of second tooth bar, rotating shaft and first handle 11 that first gear 38 and second gear 39 pass through respectively separately flexibly connect; Be provided with on first gear 38 on first swinging block, 35, the second gears 39 second swinging block 36 is set; Mounting holes 23 on nut 15 sidewalls, mounting spring 17 and steel ball 25 in the installing hole 23, spring 17 is connected with steel ball 25, offers three positioning round orifice 24 on the sidewall of first installation cavity 19, and one of them positioning round orifice 24 cooperates with steel ball 25; The structure of the handle positioner of second handle 12 and first handle 11 identical.

The operational approach and the collapsible anoscope of existing handle of the collapsible anoscope of handle of the present invention are basic identical; Difference is; When need push patient's anal with the collapsible anoscope of handle,, as shown in Figure 1 for the thrust of conveniently exerting pressure forward; First handle 11 is closed up synthetic big handle, hold so that the medical worker takes; In the time of after the collapsible anoscope of handle inserts anus, need mirror core 1 slowly being pulled out, as shown in Figure 2 for making things convenient for the application of force, earlier relative adapter sleeve 4 twist-lock rings 3 make first locating slot 5 and second locating slot 6 corresponding with first handle 11 and second handle 12 respectively; First handle 11 and second handle 12 are launched, first handle 11 snaps in respectively in first locating slot 5 and second locating slot 6 after launching with second handle 12 again; Then; Press nut 15; Nut 15 promotes spacing block set 21, first tooth bar 31 and second tooth bar 32 through connecting rod 18 and moves; First tooth bar 31 and second tooth bar 32 drive first swinging block 35 through first gear 38 and second gear 39 respectively and second swinging block 36 rotates; Until first swinging block 35 and second swinging block 36 revolve turn 90 degrees stretch out outside the handle till, first swinging block 35 and second swinging block 36 cooperate with first locating piece 7 and second locating piece 8 respectively can prevent that first handle 11 and second handle 12 from becoming Fig. 1 state by Fig. 2 state, thereby guarantees rectal examination everything goes well with your work to carry out.

After inspection finishes; The reverse nut 15 that promotes; Nut 15 drives first tooth bar 31 through connecting rod 18 and second tooth bar 32 oppositely moves; First tooth bar 31 and second tooth bar 32 drive in first swinging block 35 and second swinging block, 36 incomes, second installation cavity 30 and reset, and can close up first handle 11 and second handle 12 this moment.When non-working condition; For preventing that first handle 11 and second handle 12 from launching; Can locking ring 3 relative adapter sleeves 4 be turned an angle; Make first locating slot 5 and second locating slot 6 open certain angle with first handle 11 and second handle 12 differences respectively, thereby make 4 pairs of first handles of

adapter sleeve

11 and 12 position-limiting actions of second handle.Mounting holes 23 on nut 15 sidewalls, mounting spring 17 and steel ball 25 in the installing hole 23, spring 17 is connected with steel ball 25, offers three positioning round orifice 24 on the sidewall of first installation cavity 19, and one of them positioning round orifice 24 cooperates with steel ball 25; Positioning round orifice 24 and steel ball 25 cooperations can be worked as nut 15 and in first installation cavity 19, played the role of positioning in the moving process.

Adapter sleeve 4 can adopt following scheme with the concrete connected mode of locking ring 3: as shown in Figure 6; Arcuate groove 26 is set on the outer wall of adapter sleeve 4; Offer dowel hole 28 on the sidewall of locking ring 3, installing and locating pin 27 in the dowel hole 28, alignment pin 27 cooperates with arcuate groove 26.26 cooperations play the role of positioning to locking ring 3 alignment pin 27 with arcuate groove.

For under non-working condition, preventing mirror core 1 by checking in the lens barrel 2, as depicted in figs. 1 and 2, the inboard of first handle 11 is provided with first limited block 9, and the inboard of second handle 12 is provided with second limited block 10.When first handle 11 and second handle 12 are as shown in Figure 1 when closing up closure, first limited block 9 and second limited block 10 are positioned at the rear end of mirror core 1, and mirror core 1 is played the role of positioning.

For making things convenient for nut 15 and connecting rod 18 dismountings, as shown in Figure 3, hexagonal hole 16 in offering on the nut 15.When needing dismounting nut 15, insert interior hexagonal hole 16 with six side's spanners nut 15 is pulled down by rotation on the connecting rod 18.

The rear end mounting knob 14 of pull bar 13, handle 14 is between first handle 11 and second handle 12.When first handle 11 closed up closure with

second handle

12,14 pairs of first handles of handle 11 played a supportive role with second handle 12, make things convenient for the medical worker to the collapsible anoscope application of force of handle.

The present invention not technology contents of detailed description is known technology.
