Description
Technical field
The present invention relates to area of medical devices, be specifically related to a kind of method producing funnel breast orthopaedic plate.
Background technology
Funnel chest (Pectus excavatum is called for short PEX) refers to that constituting the breastbone of front thoracic wall, costicartilage and section of ribcage caves in funnel-form to spinal column direction.It is most commonly seen in front chest wall deformity, accounts for the 87% of front chest wall deformity, and its sickness rate is 1/300 ~ 1/400, and M-F is about 4:1.Funnel chest is also the modal chest wall deformity of child, its pathogenic factor is still not clear, the development of deformity is that Progressive symmetric erythrokeratodermia increases the weight of, the i.e. degree of deformity of breastbone increases with the age and increases the weight of, and progressively may be developed into unsymmetry funnel chest by symmetry funnel chest, Thorax volume will be caused to reduce, affect the function of respiratory circulatory system, respiratory tract infection occur, even can develop into obstructive pulmonary disease, growth promoter and mental health to child produce harmful effect.
NUSS in 1998 et al. has started Wicresoft's funnel breast orthopaedic (Minimally invasive repair of pectus excavatum is called for short MIRPE), performs the operation also known as NUSS, and the treatment of funnel chest enters Wicresoft's epoch.This operation method is to insert the suitable metal orthosis of size under breastbone to make breastbone raise, it is not necessary to the cartilage of thoracic wall before excision, and metal orthosis takes out after retaining in vivo 2 ~ 3 years.The wounds such as sternal elevation before comparing, sterno turnover operation are big, and amount of bleeding is many, and post-operative recovery is slow, the traditional method that late relapse rate is high, and NUSS operation has otch and is positioned at chest both sides, and cosmetic result is good；Need not cut off rib, tissue injury reduces；Infant is postoperative need not lie in bed for a long time, recovers fast and waits many advantages.Therefore, current NUSS operation has been widely used for clinic.
But we also noted that and come with some shortcomings in current NUSS performs the operation, such as: the particular location of operative incision, the metal orthosis i.e. shape of steel plate, fixed form etc. are only determined do not have accurate emulation experiment and mechanical analysis to assist by doctor with clinical experience.Which results in surgical effect and be heavily dependent on the subjective judgment of doctor, it may appear that in operation, repeatedly adjust the situation of plate profile, extend operating time；Meanwhile, steel plate repeatedly pierces into and passes patient thoracic cavity and too increase the probability that patient produces injury.Therefore, it is necessary to propose personalized designs and the production method of a kind of reshaping plate, to solve the problems referred to above.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of method producing funnel breast orthopaedic plate, based on thoracic CT scan data, by rebuilding the threedimensional model of breastbone frame threedimensional model design reshaping plate, utilize finite element analysis etc. to analyze means analysis reshaping plate and insert the recovery situation of thorax behind thoracic cavity, so that it is determined that reshaping plate in and out point in thoracic cavity, the geometric parameter of reshaping plate.
The technical solution used in the present invention is as described below:
A kind of method producing funnel breast orthopaedic plate, the method is according to the chest CT image of funnel chest patient, three-dimensional software is utilized to rebuild breastbone frame 3D model, with reference to normal person's thorax model and the 3D model of curvature shift design reshaping plate thereof with close thorax size, utilize finite element software, analyze funnel chest thoracic skeleton and insert the rectification shape in thoracic cavity after reshaping plate, compared with normal person's thorax, judge whether reshaping plate meets requirement, if it is determine the design parameter of reshaping plate, and utilize 3D printing technique to produce according to the threedimensional model of reshaping plate；Otherwise redesign the 3D model of reshaping plate.
Further, the method for described production funnel breast orthopaedic plate specifically includes following steps:
A) set up normal person's thorax model database, comprise thorax threedimensional model based on CT image, thorax Haller index, and the essential information of age-sex's ethnic group；

E) with normal person's thorax model as reference, primarily determine that the quantity of reshaping plate and reshaping plate insert a position at thorax；
F) with normal person's thorax model as reference, medial wall, the thoracic cavity curvature conversion trend design reshaping plate threedimensional model of access point cross section is mounted at breastbone based on thorax；
G) according to age and the thorax dimension information factor of funnel chest patient, the skeleton physical parameter at each position of thoracic cavity skeleton is determined；Determine the physical parameter of reshaping plate；Utilize finite element method or software, analyze breastbone frame rectification shape in thoracic cavity after inserting reshaping plate；
H) compared with normal person's thorax determined by Finite element analysis results and step d), it is judged that whether orthopedic result meets requirement；If meeting requirement, it is determined that reshaping plate threedimensional model and determine that reshaping plate inserts a position in thoracic cavity；Otherwise, return step f), redesign reshaping plate shape or redefine the implantation site of reshaping plate, reanalyse design and analyze, finally determining designing a model and determining the position inserted a little of reshaping plate.
Further, judgement to orthopedic result in step h), moreover it is possible to by the Haller index of the multiple horizontal cross-section of thorax compared with the normal person's thorax Haller index selected in step d).
Further, the reshaping plate threedimensional model that step f) is set up, its change of shape, length, thickness, highly, have closely related with patient's thorax size, age characteristics；Above-mentioned reshaping plate threedimensional model change of shape, length, thickness, highly, will be adjusted according to step g) and analysis h) and judged result.
Further, the reshaping plate ANALYSIS OF ORTHOPAEDICS OPERATION POLIOMYELITIS based on Finite Element Method in step g), in addition it is also necessary in limited element analysis technique or software, the thorax inserting reshaping plate is applied external force, analyze the weight that after inserting reshaping plate, thorax can bear.
Further, the threedimensional model of reshaping plate, thoracic cavity is orthopedic and under conditions of external force requirement, also size and weight to reshaping plate carries out optimization meeting, and its target is to reduce the overall weight of reshaping plate.
Relative to prior art, the invention have the advantages that
A kind of method producing funnel breast orthopaedic plate of the present invention, it is possible to according to the breast frame configuration of funnel chest patient, the shape of personalized designs reshaping plate and size, and obtain optimum reshaping plate parameter by Finite Element Method.The reshaping plate made according to personalized designs model, can effectively prevent and repeatedly adjust the injury that brings to patient of plate profile, be conducive to shortening operating time, reduces in operation wound and art, postoperative hemorrhage amount, it is ensured that postoperative rectification effect.
