Abstract
A hyperelastic hose cryoprobe comprise a probe handle and a probe connecting seat; a hyperelastic air inlet pipe is connected to the front end of the probe handle; a hose probe outer pipe is sleeved outside the hyperelastic air inlet pipe; a cold head is connected to the front end of the hose probe outer pipe; the front end of the hyperelastic air inlet pipe is arranged in the cold head; the rear part of the front end of the hyperelastic air inlet pipe is bent; the front end of the hyperelastic air inlet pipe is closed; and a throttling hole is formed on the side wall at the rear part of the front end of the hyperelastic air inlet pipe. The hyperelastic air inlet pipe is made of memory Nickel-Titaniaum alloy material. The throttling hole is a radial hole. The bending angle of the rear part of the front end of the hyperelastic air inlet pipe ranges from 1 degrees to 179 degrees. The hyperelastic hose cryoprobe has the benefits that the cold head of a probe can be contacted with lesion tissues in a bent bronchus, so that the therapeutic range of the hose cryoprobe is expanded; and in the process of operation, when being bent by doctors, the probe is not easy to break, so that the service life of the probe is prolonged.
Description
Technical field
This utility model relates to technical field of medical instruments, belong to a kind of super-elasticity flexible pipe cryoprobe, especially under bronchoscope, can bend to the limit along with scope, crooked back is external force being arranged or not having the shape that can resile under the situation of external force, to touch pathological tissues easily.
Background technology
Present flexible pipe 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 tree of pulmonary's trachea of human body is the same, and the branch of many bendings is arranged, and becoming tissue at the trachea branch interior disease that turns round needs treatment, and present flexible pipe probe can only can't be realized the treatment to these pathological tissues with the scope bending less than 70 °.In operating process, the doctor may be with 90 ° ~ 170 ° of flexible pipe probe bendings, and probe may fracture failure in this case.
The utility model content
In order to overcome present flexible pipe cryoprobe frangibility, can not to bend to the limit with scope, can not touch the deficiency of the trachea pathological tissues that turns round, this utility model provides a kind of super-elasticity flexible pipe 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 pathological tissues easily; Crooked back is external force being arranged or not having the shape that can resile under the situation of external force, to pass in and out scope easily.
For achieving the above object, this utility model is taked following technical scheme:
A kind of super-elasticity flexible pipe cryoprobe, it include probe handle. the probe Connection Block, front end in probe handle is connected with the super-elasticity air inlet pipe, be with flexible pipe probe outer tube in the outside of super-elasticity air inlet pipe, 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 the 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 a 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 this utility model technical solution problem is adopted is that the air inlet pipe of flexible pipe cryoprobe the inside adopts the super elastic marmen pipe, and utilizing the hyperelastic characteristics of memorial alloy pipe to realize can be along with the scope 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 absorbs heat when expanding than low pressure from higher pressure, causes cold head to turn cold, to realize refrigeration; 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 for use according to lesion locations, because the super-elasticity of air inlet pipe material itself, angle of bend does not influence probe and enters the scope passage, the probe cold head can touch pathological tissues on the tracheal wall easily with angle of bend after probe stretches out the scope passage, thereby realizes the treatment to these pathological changes.
The beneficial effects of the utility model are: the cold head of probe can touch the pathological changes of the bronchus the inside of turning round, and has expanded the therapeutic domain of flexible pipe cryoprobe; Frangibility not during deflectable stylet when the doctor operates has prolonged probe service life.

Label title: 1, cold head, 2, the super-elasticity air inlet pipe, 3, flexible pipe probe outer tube, 4, the scope passage, 5, probe handle, 6, the probe Connection Block, 7, throttle orifice.
The specific embodiment
Referring to Fig. 1, shown in Figure 2: a kind of super-elasticity flexible pipe 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, be with flexible pipe probe outer tube 3 in the outside of super-elasticity air inlet pipe 2, 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 the 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 memorial alloy pipe to realize can be along with scope 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 absorbs heat when expanding than low pressure from higher pressure, when gas passes through throttle orifice 7, cold head 1 temperature is reduced, to realize refrigeration; The crooked certain angle in distance super-elasticity air inlet pipe 2 blind end a distance, the angle of present embodiment is 35 °, said distance and angle have a plurality of numerical value and combination, the doctor selects for use according to lesion locations, because the super-elasticity of super-elasticity air inlet pipe 2 materials itself, angle of bend do not influence probe and enter scope and lead to 4, the cold head 1 that stretches out scope passage 4 back probes at probe can touch pathological tissues on the tracheal wall easily with angle of bend, thereby realizes the treatment to these pathological changes.
