Abstract
The invention relates to a hyperelastic hose cryoprobe which comprises a probe handle and a probe connecting base, wherein the front end of the probe handle is connected with a hyperelastic air inlet pipe; an outer hose probe casing is sheathed outside the hyperelastic air inlet pipe; the front end of the outer hose probe casing is connected with a cold junction; the front end of the hyperelastic air inlet pipe is arranged in the cold junction; the back part of the front end of the hyperelastic air inlet pipe is bent; the front end of the hyperelastic air inlet pipe is closed; the side wall at the back part of the front end of the hyperelastic air inlet pipe is provided with throttling holes; the hyperelastic air inlet pipe is made of a memory nickel-titanium alloy material; the throttling holes are radial ones; and the bending angle of the bent section at the back part of the front end of the hyperelastic air inlet pipe is 1-179 degrees. The cold junction of the probe can touch the lesion in the bent section of bronchi, thereby widening the treatment range of the hose cryoprobe. When being bent by a doctor, the probe can not be broken easily, thereby prolonging the service life of the probe.
Description
Technical field
The present invention relates to technical field of medical instruments, belong to a kind of hyperelastic hose cryoprobe, especially under bronchoscope, can bend to the limit along with scope, after crooked in the situation that external force is arranged or without the external force shape that can resile, to touch easily pathological tissues.
Background technology
Present hose cryoprobe is to enter human body by scope, can treat or pick foreign body to the pathological changes in scope mouth the place ahead.But the distribution image of pulmonary's trachea of human body tree is the same, is permitted anfractuose branch, becomes the organization need treatment at the trachea branch interior disease that turns round, and present flexible pipe probe can only with the scope bending less than 70 °, can't be realized the treatment to these pathological tissues.In operating process, the doctor may be with flexible pipe probe 90-degree bent ~ 170 °, and probe may fracture failure in this case.
Summary of the invention
In order to overcome present hose cryoprobe frangibility, can not to bend to the limit with scope, can not touch the deficiency of the trachea pathological tissues that turns round, the invention provides a kind of hyperelastic hose cryoprobe, it can be along with scope is crooked arbitrarily, can self crooked angle after probe stretches out scope, carry out cold therapy to touch easily pathological tissues; After crooked in the situation that external force is arranged or without the external force shape that can resile, to pass in and out easily scope.
For achieving the above object, the present invention takes following technical scheme:
A kind of hyperelastic hose cryoprobe, it include probe handle. the probe Connection Block, front end in probe handle is connected with the super-elasticity air inlet pipe, outer cover in the super-elasticity air inlet pipe has flexible pipe probe outer tube, front end at flexible pipe probe outer tube is connected with cold head, the front end of described super-elasticity air inlet pipe is arranged in cold head, the front end rear portion of this super-elasticity air inlet pipe is bending, the front end of this super-elasticity air inlet pipe is closed, is provided with throttle orifice on the sidewall at the front end rear portion of this super-elasticity air inlet pipe.
Described super-elasticity air inlet pipe adopts memory Ni-Ti alloy material to make.
Described throttle orifice is radial hole.
The sweeping angle of bend in front end rear portion of described super-elasticity air inlet pipe is 1 ° ~ 179 °.
The technical scheme that technical solution problem of the present invention adopts is that the air inlet pipe of hose cryoprobe the inside adopts the super elastic marmen pipe, and utilizing the hyperelastic characteristics of memory alloy pipes to realize can be along with endoscope passage is crooked arbitrarily; The front end of air inlet pipe is that the mouth of pipe of throttling end seals, and makes a call to a radial hole nearby in the blind end back, as throttle orifice, utilizes Thomson effect, and gas causes cold head to turn cold, to realize refrigeration from higher pressure heat absorption when expanding than low pressure; At the crooked certain angle in distance air inlet pipe blind end a distance, said distance and angle have a plurality of numerical value and combination, the doctor selects according to lesion locations, super-elasticity due to air inlet pipe material itself, angle of bend does not affect probe and enters endoscope passage, the probe cold head can touch pathological tissues on tracheal wall easily with angle of bend after probe stretches out endoscope passage, thereby realizes the treatment to these pathological changes.
The invention has the beneficial effects as follows: the cold head of probe can touch the pathological changes inside the bronchus of turning round, and has expanded the therapeutic domain of hose cryoprobe; Frangibility not during deflectable stylet when the doctor operates has extended probe service life.

The specific embodiment
Referring to Fig. 1, shown in Figure 2: a kind of hyperelastic hose cryoprobe, it include probe handle 5. probe Connection Block 6, front end in probe handle 5 is connected with super-elasticity air inlet pipe 2, outer cover in super-elasticity air inlet pipe 2 has flexible pipe probe outer tube 3, front end at flexible pipe probe outer tube 3 is connected with cold head 1, the front end of described super-elasticity air inlet pipe 2 is arranged in cold head 1, the front end rear portion of this super-elasticity air inlet pipe 2 is bending, the front end of this super-elasticity air inlet pipe 2 is closed, is provided with throttle orifice 7 on the sidewall at the front end rear portion of this super-elasticity air inlet pipe 2.
Described super-elasticity air inlet pipe 2 adopts memory Ni-Ti alloy material to make.
Described throttle orifice 7 is radial holes, is relatively set with two.
The sweeping angle of bend in front end rear portion of described super-elasticity air inlet pipe 2 is 1 ° ~ 179 °.
Described cold head 1 is the finger-stall shape, and front end is closed, and the rear end is opening-like, and the rear end of this cold head 1 is socketed on the front end of flexible pipe probe outer tube 3.
Described cold head 1 adopts metal material to make, and described flexible pipe probe outer tube 3 adopts nonmetallic materials to make.
Because super-elasticity air inlet pipe 2 adopts the super elastic marmen pipes, utilizing the hyperelastic characteristics of memory alloy pipes to realize can be along with endoscope passage 4 is crooked arbitrarily; The front end of super-elasticity air inlet pipe 2 is that the mouth of pipe of throttling end seals, make a call to two radial holes nearby in the blind end back, as throttle orifice 7, utilize Thomson effect, when gas from higher pressure to expand time heat absorption than low pressure, when gas passes through throttle orifice 7, cold head 1 temperature is reduced, to realize refrigeration; At the distance super-elasticity air inlet pipe 2 crooked certain angles in blind end a distance, the angle of the present embodiment is 35 °, said distance and angle have a plurality of numerical value and combination, the doctor selects according to lesion locations, due to the super-elasticity of super-elasticity air inlet pipe 2 materials itself, angle of bend does not affect probe, and to enter scope logical, and 4, the cold head 1 that stretches out endoscope passage 4 rear probes at probe can touch pathological tissues on tracheal wall easily with angle of bend, thereby realizes the treatment to these pathological changes.
