As shown in figs 6-8, in the use of the present invention, carrying out reducing adjusting first with regulating device, application area is adapted to
Size.It is determined according to application area and smears diameter, if diameter is smaller, the effect gathered using 21 inside of adjustment cap, under
Side buckles into, 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 needing the area smeared larger, the effect expanded using 21 lateral surface of adjustment cap, adjustment cap 21
It is inserted into from below, 11 end of outlet tube fitting 21 lateral surface of adjustment cap moves outward, and the diameter of formation becomes larger, and is adapted to great Qu
The area in domain is smeared.When controlling to adjust outlet tube 11, suction pipe 12 follows the movement variation of outlet tube 11, and can realize and pass through tune
Control the spacing between plate 15 and the link position adjusting suction pipe 12 and outlet tube 11 of outlet tube 11.The positioning of outlet tube 11 can be according to
It is realized by the rotation connection frictional resistance of 11 top of outlet tube and mounting hole 9.The size for adjusting diameter, according to practical application area
Diameter marks in adjustment cap 21, and 11 end of outlet tube reaches marker bit.
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 profit
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, rate and rate of temperature fall are smeared 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 flowing
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, evaporated in resorption protection process.
As shown in Fig. 6,8, in adjustment process, 11 terminal position of outlet tube and pathological tissues surface engagement, and suction 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
It is detached from spacing ring 14.Adjustment cap 21 is divide into upper part and lower part, generally do gather effect when, the conical section on top can be real
Existing, the round platform part of lower part may then interfere at this time, likewise, generally when doing dilating effect, the round platform portion of lower part
Divide and can be realized, therefore adjustment cap 21 is divide into upper part and lower part, fractionation is more convenient to use, is becoming path or path from major diameter
When becoming major diameter, then need adjustment cap 21 integrally using can easily realize gathering or expanding for enough adjustable ranges.
When pathological tissues are smaller, a certain number of outlet tubes 11 can cover whole surface, the mobility of smearing and
The conduction of heat, you can meet smearing demand；And when application area is larger or the quantity of outlet tube 11 cannot achieve perfection
When covering, whole rotation can be realized by power plant, meets and smears area coverage, realize that uniformly fast and effectively liquid nitrogen applies
It smears.Driving motor 26 is opened, is rubbed by rubber wheel 27 and carrier 2 is driven to rotate, then by the connection function of spindle rod 1, is applied
Liquid protective device integrally carries 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, using adjusting
The adjusting again of cap 21 changes the region of covering, realizes comprehensive uniform directly smearing.Smearing to adapt to small diameter is covered
Lid, then the quantity of outlet tube 11 should be less, and when reducing, which is adjusted, adapts to larger diameter, the quantity of outlet tube 11 cannot achieve
Even covering, the rotation that cooperation power plant drives, which can be realized, uniformly directly smears.
The test side of infrared measurement of temperature module 29 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 controlling indicator light 30 by processor.
Graduation mark 31 be used for prompt reducing adjust as a result, keeping adjusting more accurate, graduation mark 31 can directly be converted into change
Diameter size is shown that inner and outer diameter and the surrounded diameter in 11 end of outlet tube of 21 different height position of adjustment cap are one
One correspondence can carry out conversion or practical measurement etc., realize the conversion label of graduation mark 31, directly display the big of reducing
It is small, and it is contemplated that the thickness of 21 shell of adjustment cap, the label for gathering and expanding two different parameters is realized as needed.
