Description
Technical field
The utility model is related to the Interventional Ultrasound instrument field in medical instrument, especially a kind of long handle probe Interventional Ultrasound
Paracentesis depth control device.
Background technology
Interventional Ultrasound（interventional ultrasound）It is on the basis of ultrasonoscopy, further to meet
The needs of clinical diagnosis and treatment and a special kind of skill to grow up, are the extension and development of ultrasonic clinical application, main special
Putting is：Under the dynamic surveillance of real-time ultrasound or guiding, direct transdermal is punctured accurately is placed in lesion, capsule by puncture needle or conduit
In chamber or pipeline configuration, the operations such as various aspiration biopsies, radiography, drainage, drug-injection in treatment are completed.The technology, which has, compares surgery hand
The advantages such as art wound is small, and patient's post-operative recovery is fast, and treatment effect is definite, are widely used in clinic, such as：Ultrasonic guidance vagina,
The aspiration biopsy of the internal organs occupying lesion such as uterus, ovary, enteron aisle and prostate；The puncture hardening treating of ultrasonic guidance；Ultrasound
Guide the ablations such as microwave, the radio frequency of tumour.In puncturing implementation process, to avoid penetration damage peripheral organs, tissue, god
Through etc. blood vessel inside important features and target focus, paracentesis depth is the factor that operates doctor and must take into account.
Especially in situations, the accurate assurance of paracentesis depth directly influences the success rate and peripheral group of puncture diagnosis
Knit degree of injury：
1, pelvic cavity or during the Cystic lesions puncture diagnosis of pelvic cavity viscera, after cyst fluid extraction, cyst wall collapses, and wears
The variation of felting-needle depth may lead to spike pierces cyst wall or exit blister cavities, and puncture needle is made to reach the position other than blister cavities, and
Lead to drug-injection in treatment failure even serious consequence, such as：Infusion of medicine tissue space can cause inflammatory reaction, or even organize bad
Extremely.
2, when the puncture ablation of ultrasonic guidance tumour, it can determine what tumour did not melted thoroughly using contrast-enhanced ultrasound technique
Region is needed at this time accurately to these further ablations of residual lesions row, and the fixation of paracentesis depth can help thoroughly
Ablation residual lesions and the damage for reducing surrounding normal tissue.
When 3, compared with the aspiration biopsy of small lesion, puncture needle change in depth causes puncture needle to deviate lesion and lead to biopsy extraction
Failure.
4, internal blood supply is abundant and privileged sites, such as：The lesions such as bottleneck throat, thyroid gland and parathyroid gland, Hilar
When aspiration biopsy and ablation, the weight such as the too deep tracheae that may lead to surrounding of paracentesis depth, oesophagus, recurrent nerve, portal vein
Structural damage is wanted, and paracentesis depth is excessively shallow to cause ablation to be not thorough.However the accurate assurance of paracentesis depth is one
The technical barrier of straight puzzlement Interventional Ultrasound doctor.Since paracentesis depth can not be held, keep some Interventional Ultrasound risk assessment excessively high
And it cannot implement.In Interventional Ultrasound diagnosis and treatment process, puncture needle typically is fixed with hand by operation doctor, to prevent being led because of maloperation
It causes puncture needle inserting needle too deep or exits puncture target, cause to damage surrounding vitals or affect the treatment.But actual mechanical process
In, Interventional Ultrasound doctor is difficult to remain that the depth of puncture needle is constant, and a hand will necessarily shadow for fixing puncture needle
It rings to other complicated operation of diagnosis and treatment for needing both hands to carry out.Therefore, it is accurately controlled the depth of puncture, it is super for improving intervention
Sound diagnosis and treatment success rate and to effectively reduce complication extremely important.At present in the domestic pricking device for Interventional Ultrasound, not yet
Any producer, which provides, can be used for fixing, controls and finely tune the equipment of puncture needle depth.
103340655 A of Chinese patent literature CN describe a kind of puncture needle detecting device based on ultrasound examination, packet
Ultrasonic probe and puncture needle are included, ultrasonic probe is connect with control unit, and first angle sensing is equipped on ultrasonic probe
Device, the affixed second angle sensor in end of puncture needle, benchmark of the first angle sensor as second angle sensor.The reality
With the novel interspersed angle for assisting adjustment puncture tube using angular transducer, improve puncture needle inserts position and insertion depth
Accuracy, facilitate healthcare givers operation, improve medical efficiency.But the manual progress of doctor is still needed to using the structure
Adjustment still has higher operation difficulty.
