Description
Technical field
This utility model relates to a kind of tumor cryoablation probe, particularly a kind of ultra-fine tumor cryoablation probe of the band dilating sacculus for the privileged sites tumor operation such as near pulmonary, brain, trunk.
Background technology
2014 version " report of world's cancer " predict that global cases of cancer will present swift and violent growing trend, by 1,900 ten thousand people of 1,400 ten thousand people's cumulative year after year to 2025 of 2012 year, 2,400 ten thousand people will be reached by 2035; Within 2012, the whole world increases 1,400 ten thousand cases of cancers newly altogether and has 8,200,000 people dead.Wherein, newly-increased 3,070,000 cancer patients of China also cause about 2,200,000 people dead, account for 21.9% and 26.8% of global total amount respectively.Visible, the life and health of the cancer serious threat mankind.
Excision, radiotherapy, chemotherapy are that these three kinds traditional tumor therapeuticing methods are very large to patient's injury, have a strong impact on life in patients, cause comparatively widely for the arguement of tumor patient " over-treatment ".Meanwhile, because the reason such as tumor patient physical function is poor, only have the tumor patient of about about 20% can accept surgical resection, therefore, tumor micro-wound ablation technology is just becoming the forward position of contemporary clinical medical development.Cryoablation wherein a kind ofly has the technology representing meaning, and it is mainly through cryosurgery tool, controlledly makes lesion tissue experience lower the temperature, freezes, rewarming process, thus cause irreversible damage and the necrosis of tumor cell.When cryoablation treatment, for destroying tumor tissues, probe will reach enough low low temperature, and the non-targeted district of ablation probe must have good heat-insulating property, to avoid the normal structure on cold injury puncture path.
Cryoablation probe the thinnest is in the world Cryo-HITTM Galileo argon helium knife at present, diameter 1.47mm, be more convenient for operating, puncture more easily, more smooth and easy, normal tissue damage is less, and complication rate is low, is particularly useful for pulmonary, brain, the tumor of privileged sites such as near trunk, clinical practice is when pulmonary carcinoma, and pneumothorax incidence rate is starkly lower than the pneumothorax incidence rate of 2mm probe.But it exists following shortcoming: 1. be not with temperature sense thermocouple in probe, need temperature in monitoring tissue, temperature probe must be inserted in addition; 2. non-targeted district vacuum insulation wall construction is complicated, and cost is high, under external force or the long period store, easily cause the phenomenons such as gas leakage, affect insulation effect.
Summary of the invention
This utility model can not monitor temperature in target tissue for the Cryo-HITTM Galileo argon helium knife of existing 1.47mm diameter; non-targeted district vacuum insulation wall cost is high, easily leak gas; effectively cannot protect the defect of normal structure; a kind of ultra-fine tumor cryoablation probe with dilating sacculus is provided; this probe diameter only 1mm; have the function of probe target to district's real-time and precise thermometric and non-targeted district heat-insulation and heat-preservation, protection normal structure concurrently, the oncotherapy privileged sites such as being applicable near pulmonary, brain, trunk that can be safer and more effective.
The technical solution of the utility model is: a kind of ultra-fine tumor cryoablation probe with dilating sacculus, comprise housing, sacculus, film thermocouple, insulating barrier, be characterized in: housing is made up of targeting district integrally and non-targeted district, non-targeted district is fixed with sacculus, non-targeted district tail end arranges the air-filled pore of dilating sacculus, and blocks the seal cover of gas after being furnished with inflation.Targeting district outer wall is coated with film thermocouple, is coated with insulating barrier between housing and film thermocouple.
Housing outer diameter is 1mm, and is made up of medical stainless steel or nichrome material.
Sacculus is made up of polyamide-based macromolecular material, modified polyamide macromolecular material or polymer composite.Sacculus is fixed in non-targeted district by thermal weld or laser weld.
After being filled with the low gas flaring of heat conductivity by air-filled pore in sacculus, its diameter can reach 3-5mm, and shape is cylindrical or calabash shaped.
Film thermocouple be cover between 1 ~ 5 group of temperature measuring area-200 DEG C ~ 150 DEG C K type, N-type, E type, J type or T-shaped thermocouple, and share the thermode of a material of the same race.
Insulating barrier is SiO
2, Al
2o
3, Parylen or teflon coatings.
The beneficial effects of the utility model are:
1. the ultra-fine cryoablation probe of 1mm, convenient operation, puncture more easily, more smooth and easy, normal tissue damage is less, complication rate is low, alleviates patient suffering and medical-risk, even if piercing blood vessel, after cryoablation, wound still can be recovered, and is applicable to pulmonary, brain, the tumor operation of privileged sites such as near trunk;
2. when cryoablation probe inserts target area tissue, after the sacculus air inlet in the non-targeted district of probe housing, expansion is expanded, form sacculus isolating membrane, probe and normal structure are kept apart, the gas that in sacculus, heat conductivity is extremely low has heat-insulating property, avoids probe housing because heat insulating function is not good, the cold spilt or heat to be directly acted on the normal structure of probe housing contact;
3. in ablative surgery, film thermocouple can the temperature of measuring probe targeting district plurality of positions in real time, is supplied to doctor's precisely actual therapeutic temperature reliably, facilitates surgical operation, improve ablation effect.
