As shown in Figs. 1-5, in the use of the present invention, carrying out variable diameter adjusting first with regulating device, application area is adapted to
Size.Control-rod 21 slides up and down in groove 22, and sliding is driven to move up movement, when sliding block 23 moves down, sliding block 23
24 top of locating rod is driven to move down, 24 end of locating rod outward struts 11 top of outlet tube, and 11 top of outlet tube is outside
Side is mobile, then 11 lower end of outlet tube is collapsed inwardly, and the round diameter that 11 end of outlet tube is surrounded becomes smaller, and is adapted to zonule
Area smear；Opposite, when control-rod 21 is moved up with movable slider 23,11 end of outlet tube is moved outward, formation it is straight
Diameter becomes larger, and the area for being adapted to big region is smeared.As shown in fig. 6, sliding block 23 control to adjust outlet tube 11 when, suction pipe 12 with
Change with outlet tube 11 is mobile, and can realize and suction pipe 12 and liquid out are adjusted by the link position of regulation plate 15 and outlet tube 11
Spacing between pipe 11.The positioning of outlet tube 11 can be by the frictional resistance and outlet tube 11 between control-rod 21 and groove 22
The rotation connection frictional resistance of top and mounting hole 9 realizes that, using the sliding block 23 of " C " font, notch can cooperate with strut 3,
The a wide range of mobile up and down of sliding block 23 is realized, without influencing being located by connecting for carrier 2 and spindle rod 1.
As shown in figure 4, after the completion of being adjusted according to practical application area (application area may be slightly larger than lesion tissue), in benefit
When carrying out liquid nitrogen smearing to lesion tissue with masking liquid protective device, liquid nitrogen is poured into liquid supply box 4, the shunting through feed liquid hose 7,
It is applied in lesion tissue region from the outflow of each outlet tube 11, the heat absorption of liquid nitrogen rapid evaporation.Lesion tissue cell is freezed to death, is matched
The recycling protection for closing suction pipe 12 can carry out appropriate excessive liquid nitrogen supply and smear, smear rate and rate of temperature fall to improve, more
Remaining liquid nitrogen in lesion tissue when outflowing, (the spacer region between suction pipe 12 and outlet tube 11 outside the range for allowing to flow
It is overseas), it can be drawn by suction pipe 12.Start exhaust pump 20, the exhaust of exhaust pump 20 blows to recycling bins 5, forms siphon, suction pipe
Extra liquid nitrogen near 12 end port negative pressure absorbings avoids liquid nitrogen continuation is outer from flowing to normal group that human body is not required to freezing processing
It knits.Affected by environment, liquid nitrogen may not be recovered to recycling bins 5, evaporate in resorption protection process.
In adjustment process, according to lesion adjusting slider 23, make 11 end of outlet tube close to pathological tissues surface, and resorption
Pipe 12 can rely on gravity, be bonded adaptation with surface automatically, gravitational effects can be improved in the setting of counterweight ring 13, while avoiding suction pipe
12 are detached from stop collar 14.
As shown in Figure 4,5, when pathological tissues are smaller, a certain number of outlet tubes 11 can cover whole surface, smear
Mobility and heat conduction, smearing demand can be met；And when application area is larger or the quantity of outlet tube 11
When cannot achieve perfect covering, whole rotation can be realized by power device, meets and smears area coverage, realized uniformly effective
Quick liquid nitrogen is smeared.Driving motor 29 is opened, is rubbed by rubber wheel 30 and carrier 2 is driven to rotate, then passes through spindle rod 1
Connection function, masking liquid protective device integrally carry out rotation at a slow speed, then outlet tube 11 can directly overlie entire smearing surface.
If application area is larger, when can not disposably realize the covering in centre and peripheral position, sliding block can be passed through
23 mobile progress variable diameter adjustings, change the region of covering, realize and comprehensively uniformly directly smear.For the smearing for adapting to small diameter
Covering, then the quantity of outlet tube 11 should be less, and when variable diameter, which is adjusted, adapts to larger diameter, the quantity of outlet tube 11 be cannot achieve
Uniform fold, the rotation that cooperation power device drives, which can be realized, uniformly directly smears.
The test side of infrared measurement of temperature module 32 carries out temperature detection to tissue, and output detects signal and by processor judgement
Reason, the display of different conditions can be carried out by processor control instructions lamp 33.
Graduation mark 34 be used for prompt variable diameter adjust as a result, make adjust it is more accurate, graduation mark 34 can directly display control
Bar 21 moves up height, or can directly be converted into variable diameter size and be shown, control-rod 21 with movable slider 23 move up and down with
The surrounded diameter in 11 end of outlet tube is one-to-one relationship, can carry out conversion or actual measurement etc., realizes graduation mark
34 conversion label, directly displays the size of variable diameter.
