Description
Technical field
The utility model relates to a kind of device of technical field of medical instruments, specifically is a kind of location follower that is used for cranium jaw face surgical navigational.
Background technology
In traditional surgical operation, the doctor often can only or have the wound detection means to obtain diagnostic message by indirect method, as observe CT faultage image, ultrasound diagnosis, operations research etc., and then the experience that relies on the doctor is implemented operation, this mode is difficult for accurately grasping the space coordinates of some crucial physiology point of surgical object, and the operative site polarization is poor.
Along with the continuous development of medical skill, surgical operation is more and more paid attention to becoming more meticulous and Wicresoftization, and operation guiding system arises at the historic moment.In the surgical navigational process, at first to set up the relation between preceding CT model of art and patient locus, i.e. registration process; Then effectively according to surgery planning, the guiding in real time operation is carried out, the computer operation guiding system combines space multistory airmanship, computer image processing technology with clinical operation, operative site and operating theater instruments relative position are shown in real time, the doctor can understand the operating theater instruments relative position at any time, increases operation safety.Because its advantage is more, the application of computer navigation operation in craniomaxillofacial surgery is also increasingly extensive.
Use at present maximum registration process to be based on a little registration clinically.Adopt at first be clinically anatomic points as the register mark point, but in the three-dimensional visualization image, definite existence fixed point error of anatomic points locus.As improvement, a utility model " CT navigating surgery positioning mark point " (patent No. CN200820127401.3) has disclosed a kind of CT navigating surgery telltale mark point.The described gauge point of this patent comprises that X ray resistance penetrates nominal volume and the X ray resistance that the high material of rate constitutes and penetrate the registration body that the low material of rate constitutes, and the sticker that gauge point is fixed on human body surface is arranged below the affiliated registration body.Aforementioned CT navigating surgery gauge point only is fixed on human body surface by sticker with index point, poor stability.And the skin of human body surface exists displacement and distortion, is easy to generate the image drift.
The image drift is the key factor that influences the operation guiding system accuracy.It is systemic image drift that the image drift has two classes, a class, and another kind of is structural image drift.The former and locator markers displacement, the headstock is loosening, and registration tense marker thing slippages etc. are relevant, and the latter is shifted with patient tissue, distortion is relevant, and therefore the fixing and the stability of location and tracking means are very important.
In the surgical navigational of existing optical positioning system, all be as benchmark under many situations with patient's position, this just requires operating-table or patient's relative position sensor is immobilized relatively, and in actual surgery, will move or rotate the surgical object operation that undergos surgery inevitably, and the variation of these positions bring error can for the computer surgical navigational.Find through retrieval prior art, Chinese patent application numbers 200910179682.6 discloses a kind of fixing scaffold for surgical guidance, this technology is fixed by patient in skull hold-down screw and the art, add again that the patient supports the location in three locating rods and the art, form three strong points and a fixing point in support and the art between the patient, make fixed mount and patient position relation keep constant, improve the surgical navigational precision.Said apparatus needs to implant skull in the art, has prolonged operating time, has increased operation wound.
The utility model content
This utility model is at the prior art above shortcomings, a kind of location follower that is used for cranium jaw face surgical navigational is provided, the register mark thing is with respect to the position good reproducibility of cranio-maxillofacial, and the register mark thing can reach ideal spatial distribution, the position is accurate during registration, has improved registration accuracy; Be fixed with position sensor on the registration trace component, do not need other placement location pick off, reduce error.Obtaining the iconography data and performing the operation interval, the registration trace component can take off, and has reduced operation wound to greatest extent.
This utility model is achieved through the following technical solutions, and this utility model comprises: fixation kit and the registration trace component two parts that are attached thereto.
Fix by connector between described fixation kit and the registration trace component.
Described connector is screw or rivet.
The inner surface of described fixation kit and the surface configuration of denture match.
Described fixation kit is provided with several abutment portion, has through hole at the center position of abutment portion.
Described registration trace component is made up of register mark thing, position sensor, matrix part and four extensions, wherein: two extensions in four extensions and matrix part be in same plane and each other angle be 90 degree, the two other extension is vertical with matrix part respectively, four register mark things are arranged at the end of corresponding extension respectively, and four position sensors are arranged at the middle part of corresponding extension.
Described matrix part has tapped through hole, and is corresponding with fixation kit tapped through hole position.
Described position sensing implement body be positioned at every extension terminal with the register mark thing at a distance of the 5mm place.
The center of described register mark thing is a concave point.
Described position sensor is light emitting diode or fluorescence ball.
Compared with prior art, advantage of the present utility model is: the label that is used for registration is by fixture and denture driving fit, thereby reaches and the rigidly fixing of cranio-maxillofacial; Be fixed with position sensor on the registration trace component, do not need other placement location pick off, reduce error.Obtaining the iconography data and performing the operation interval, whole location follower can take off, and has reduced operation wound to greatest extent.
