Description
Technical field
This utility model is a kind of CT positioning percutaneously inserting puncture instrument, is used for the guiding location that percutaneous intervene operation puncture needle or other percutaneous are inserted apparatus.
Background technology
A large amount of clinical datas show: belonged to middle and advanced stage when the tumor patient of 70-80% is made a definite diagnosis, the chance of forfeiture excision.Traditional radiotherapy, chemotherapy are because of being subjected to restriction such as dosage, and difficult with the tumor cell complete inactivation, therapeutic effect is undesirable.In recent years, carrying out of physics ablation method such as new targeting ablation therapeutic technology such as laser, freezing, radio frequency, microwave changed the theory of traditional oncotherapy.Targeted therapy will be treated probe by percutaneous puncture exactly and will be sent to tumor locus, and ablation is carried out in the tumor target area, thus deactivation tumor cell and reduce normal surrounding tissue damage to greatest extent.Along with the development of image technology, provide guarantee for accurately formulating the tumor target area.Carry out CT scan before the treatment earlier, design tumor puncture all target spots and labelling skin penetrating point, the computer measurement design puncture path degree of depth, the three-dimensional ablation range of angle and target area.After treatment plan is formulated and finished, treatment plan should strictly be carried out in the operation puncturing process, to guarantee curative effect and safety.The tumor that in the past punctured target spot is free-hand blind wearing owing to lack accurate directional guiding device, and is poor because of angle grasp degree of accuracy, needs repeatedly the monitoring of CT real time scan in the operation, adjusts to reach designing requirement.
In the neurosurgery stereotactic surgery, for making the patient space consistent with the image space coordinate, usually use local anesthesia, the stereotactic frame of metal is fixed on patient's skull forms rigid structure, on stereotactic frame, be connected with the puncture guider, the puncture direction is fixed on the surgical planning before the art.The misery and the use inconvenience that bring to patient are unfavorable for applying.Along with the development of three-dimensional fix technology, computer navigation system is applied to stereotactic surgery, is called frameless stereotactic surgery, uses joint arm to be installed on the operation headstock or use robot assist location puncture positioning device.And be positioned at the tumor of non-brain position, because body surface is fixedly puncture guider of soft tissue, make puncture needle thrust the image space of human body and the coordinate setting that the focus space is difficult to agree.So can't use the stereotactic frame of neurosurgery.
Nineteen fifty-three, Sweden radiologist Seldinger has founded the percutaneous puncture technology, is referred to as the Seldinger technology, and it is the foundation stone of modern interventional radiology diagnosis and treatment technology.Through the development in more than 50 years, the interventional therapy under the image-guided became the third-largest diagnostic and therapeutic system that is listed in the department of medicine and surgery treatment.
Interventional radiologic therapy is to adopt the displacement of puncture needle, seal wire and catheter sheath will treat conduit and apparatus to deliver to the pathological changes target spot and treat, and can be divided into vascular interventional therapy and non-vascular interventional therapy.The non-vascular interventional therapy is divided into intervention property puncture diagnosis and treatment technology, intervention property puncture drainage technology, intervention property calculus removal surgery, intervention property luminal stenosis dilatation and stent endoprosthesis, the malignant tumor non-vascular is got involved the targeting ablation art.
The interventional therapy of tumor is to adopt the percutaneous puncture technology that freezing cutter, rf probe etc. are presented under X line, CT, MR, image documentation equipment guiding such as ultrasonic to carry out targeting ablation therapeutic in the tumor focus.Targeted therapy directly works to tumor, and lethality is big, and is little to the normal surrounding tissue influence.Operation wound is little, and recovery time is short, probe, one of important directions that becomes oncotherapy evident in efficacy.
The non-vascular interventional treatment of tumor adopts B ultrasonic or CT image-guided mostly.B ultrasonic energy realtime imaging, simple to operate, but the B ultrasonic location is low because of 3-D solid structure, the resolution of the difficult reflection tumor of its two-dimensional imaging, if B ultrasonic doctor location technology is unskilled, surgical doctor is relatively poor to the B ultrasonic image understanding, will directly influence localized accuracy of puncture and therapeutic effect.But the CT image has resolution height fault imaging and three-dimensional image is rebuild function, the doctor can according to shown knub position, size, form and with the relation of surrounding tissue, formulate best surgical planning, i.e. the quantity of required puncture, the aspect of inserting needle, best entry point, best target position etc.Therefore open C T guiding interventional therapy operation down can be formulated more detailed operation plan, can make that monitoring accuracy is improved in location, guided puncture and the art, improves the effect of finally treating.
CT guiding tumor intervention therapeutic key factor down is whether the direction that enters of puncture needle is consistent with plan before the art with the position, and as the inaccurate area for treatment disengaging tumor region that causes of target spot localised puncture, tumor region is part deactivation or complete inactivation not only.How accurately the guided puncture location is most important.Usually the percutaneous puncture process under the CT guiding is roughly as follows:
1, the CT image of scanning lesions position before the art carries out three-dimensional reconstruction.Analyze the 3 D stereo anatomy relationship of tumor and structures surrounding, design tumor puncture target spot and ablation range make the damage scope greater than tumor tissues edge 1cm.As shown in Figure 1, in most cases for guaranteeing that therapeutic effect need design many target spots synchronous therapeutic scheme (Zhang Jiren usually, Liu Ruiqi. tumor naturopathy new technique. the People's Medical Officer Press, 2005.), should determine quantity, angle, the degree of depth, the skin entry point coordinate of puncture needle and the target coordinate that punctures before this many target spots synchronous therapeutic scheme art.
2, patient carries out CT scan after entering operating room again.Paste telltale mark at the tumor locus body surface before the scanning, metal (or plastics) fence that common employing can be developed or location paper on the CT image.After the scanning, carry out image analysing computer once more, with reference to the plan of formulating before the art, and careful measuring and calculating, finally determine tumor puncture target spot and skin penetrating point, finish operation designing after, all target spots and skin penetrating point are connected one to one, and the coordinate parameters of corresponding point to point is location of operation puncture parameter.
3, after above-mentioned localised puncture parameter is determined, can be by means of the axle position fault plane cursor on the CT equipment, open this cursor and be the X-axis of the elements of a fix at the projection line of patient's body surface, skin penetrating is put the count intersection point of (Y-axis) and CT cursor of pairing body surface telltale mark and can be defined as the skin entry point during design, with the marking pen that do not fade in the enterprising row labels of skin.
4, the skin entry point promptly begins the tumor target spot that punctures after determining.Usually determine that by protractor needle angle and design puncture angle are consistent as far as possible in the puncture, but often error is bigger owing to free-hand operation in the actual mechanical process, the abecedarian is difficult to once successfully accurately sting accurate design target spot.Often in piercing process, need repeatedly CT scan to confirm and the angle of adjustment puncture needle and the angle of human body fault plane.Operating time prolongs, patient's radiation dose increases greatly thereby make.Increase owing to repeated localised puncture and tumor target spot puncture poor accuracy makes postoperative complication, and directly influence therapeutic effect.This utility model has solved the guiding problem of puncture needle in the piercing process rightly, has simplified the technology content of stereotactic puncture, the tumor target spot even if the abecedarian also can puncture exactly.Operating time has effectively been shortened in once success of majority in the puncture, has reduced the amount of radiation of the passive acceptance of patient, makes the accuracy of percutaneous targeting puncture obtain the significance raising, is easy to popularize.
In addition, the horseley-Clarke technique that aforementioned neurosurgery is used is difficult to be applied in the operation at other positions of human body, main cause is that the soft tissue at other positions of human body is fixing with respect to osseous tissue position on every side, the coordinate setting that makes image space and patient space be difficult to agree.Therefore the fixed guide locating device provided direction of puncture can being fixed up of neither one gone back in the intervention at other positions of human body puncture, usually use the guiding of real-time CT image, but because the puncture guiding is not located, still there is the blindness in the piercing process, puncture instrument in doctor's hands does not have objective accurate position mark, be difficult in the piercing process puncture needle is fixed on the projected path, can only be with doctor individual's experience, need constantly carry out image scan and adjust direction, final result may still have certain deviation with desirable Planned Route, and time-consuming and influence therapeutic effect.
