Description
Technical field
The Interventional Ultrasound instrument field in medicine equipment is the utility model is related to, particularly a kind of convex array 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 for growing up, it is the extension and development of ultrasonic clinical practice, it is main special
Putting is：Under the dynamic surveillance of real-time ultrasound or guiding, direct transdermal punctures accurately inserts focus, capsule by puncture needle or conduit
In chamber or pipeline configuration, the operation such as various aspiration biopsies, radiography, drainage, drug-injection in treatment is completed.The technology, which has, compares surgery hand
Art wound is small, and patient's post-operative recovery is fast, the advantages such as treatment effect is definite, is widely used in clinic, such as：Ultrasonic guidance liver,
The aspiration biopsy of kidney, prostate, lymph node and all kinds of occupying lesions etc.；Ultrasound-guided Percutaneous liver puncture biliary drainage
(percutaneous transhepatic cholangial drainage, PTCD)；Ultrasound-guided Percutaneous liver, renal cyst
Puncture hardening treating；The ablations such as the microwave of ultrasonic guidance tumour, radio frequency.In implementation process is punctured, damaged to avoid puncturing
Hinder the blood vessel inside the important features such as peripheral organs, tissue, nerve and target focus, paracentesis depth is that operation doctor must account for
Factor.
Especially in situations, the accurate assurance of paracentesis depth directly influences the success rate and peripheral group of puncture diagnosis
Knit degree of injury：
1st, during liver, Percutaneous Puncture Sclerosing Treatment of Renal Cysts, after cyst fluid is extracted out, cyst wall collapses, and the change of puncture needle depth can
Spike pierces cyst wall can be caused or exit blister cavities, puncture needle is reached the position beyond blister cavities, and cause drug-injection in treatment to fail
Even serious consequence, such as：Infusion of medicine tissue space can cause inflammatory reaction, or even necrosis.
2nd, during the puncture ablation of ultrasonic guidance tumour, it can determine that tumour does not melt thoroughly using contrast-enhanced ultrasound technique
Region, now need accurately to these further ablations of residual lesions row, the fixation of paracentesis depth can help thorough
Melt residual lesions and reduce the damage of surrounding normal tissue in bottom.
When the 3rd, compared with the aspiration biopsy of small lesion, puncture needle change in depth causes puncture needle to deviate focus and cause biopsy extraction
Failure.
4th, internal blood supply is abundant and privileged sites, such as：The focus 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 cause surrounding of paracentesis depth, oesophagus, recurrent nerve, portal vein
Structural damage is wanted, and paracentesis depth is excessively shallow that ablation may be caused not thorough.But the accurate assurance of paracentesis depth is one
The technical barrier of straight puzzlement Interventional Ultrasound doctor.Due to paracentesis depth can not be held, make some Interventional Ultrasound risk assessment too high
And it can not 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
Cause puncture needle inserting needle too deep or exit 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
Ring to other complicated operation of diagnosis and treatment for needing both hands to carry out.Therefore, the depth of puncture is accurately controlled, it is super for improving intervention
Sound diagnosis and treatment success rate and effectively reduction complication are extremely important.It is domestic at present to be used in the pricking device of Interventional Ultrasound, do not have also
Any producer provides the equipment that can be used for fixing, control and finely tune puncture needle depth.
The A of Chinese patent literature CN 103340655 describe a kind of puncture needle detecting device based on ultrasound examination, bag
Ultrasonic probe and puncture needle are included, ultrasonic probe is connected with control unit, and first angle sensing is provided with 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 new interspersed angle that adjustment puncture tube is aided in using angular transducer, improve puncture needle inserts position and insertion depth
Accuracy, facilitate the operation of healthcare givers, improve medical efficiency.But the manual progress of doctor is still needed to using the structure
Adjustment, still has higher operation difficulty.
