Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, especially a kind of localized needle guiding support device that is used to puncture.
Background technology
When inside of human body generation pathological changes, need to utilize puncture that focus is carried out biopsy or treatment sometimes.Normally determine the orientation of focus and skin anchor point and the degree of depth of puncture needle by means of instrument such as CT scan device, at first on the cross section of human body, measure the position of focus, in this aspect, select best inserting needle position and needle angle, utilize the three-dimensional structure picture decision focus of inserting needle aspect, needle angle and depth of needle and the exact position of lancet puncture.Though the CT scan device can be determined three-dimensional needle angle and depth of needle exactly, but the process of puncture is all carried out patient after the CT scan aspect shifts out, when patient leaves the CT scan device, the doctor can only be according to the judgement of oneself, determine an inserting needle direction roughly, puncture, and then carry out CT scan and confirmed.Concrete piercing process is 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.In most cases, should determine quantity, angle, the degree of depth, the skin entry point coordinate and puncture target coordinate of puncture needle before this many target spots synchronous therapeutic scheme art for guaranteeing that therapeutic effect need design many target spots synchronous therapeutic scheme usually.
2) patient carries out CT scan after entering operating room again.Paste telltale mark at the tumor locus body surface before the scanning, metal that common employing can be developed or plastics fence 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, final definite tumor puncture target spot and skin penetrating point, after finishing operation designing, all target spots and skin penetrating point are connected one to one, the coordinate parameters of corresponding point to point such as angle, the degree of depth are 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.
