Description

A kind of prosthese that can automatically extend
Technical field
The invention belongs to Implantable Medical Device articles for use field, it is specifically related to a kind of limb-sparing surgery apparatus prosthese that can automatically extend.
Background technology
Children are the colonies occurred frequently of the primary malignant neoplasm such as osteosarcoma and Ewing sarcoma, along with carrying out of new adjuvant chemotherapy mode, 5 years survival rates of such patient rise to 70%. Therefore such more and more patients is under the prerequisite saved one's life, it is desired to recover limb function to greatest extent.
Recover limb function it is generally required to patient does limb-sparing surgery. Traditional limb-sparing surgery is prosthetic replacement or allogenic bone transplantation. But, traditional limb-sparing surgery is not highly suitable for child patient, and reason is, children are in growing, and health is being grown taller gradually. So, along with the growth of child age, leg length discrepancy can be caused, cause life inconvenience.
For this reason, researchist has designed the implantable prosthese that can extend, and its ultimate principle is the requirement that the prolongation by prosthese meets children's length. It is be set to be threaded or other dismountable mode of connection with the junction in joint at upper prosthese and lower prosthese such as existing conventional a kind of prosthese extended, then when needs extend limbs, by the prosthese implanted by surgical exposure out, utilize special tool screw thread to be turned on a part or is slided by upper and lower prosthese opposed articulation and pull open a part, the distance in prosthese or lower prosthese and joint is extended, then sew up, solve the problem that leg length discrepancy brings. But, the prolongation of this type of prosthese needs repeatedly to carry out within the children growth phase, and the long-time clinical observation of surgeon finds that it exists following drawback: first, it is necessary to again or repeatedly perform the operation, each surgery cost is 5-8 ten thousand yuan, causes the high burden of patients ' psychological and economy; Secondly, repeatedly operation can cause Prosthesis related infections risk to strengthen, and once Prosthesis related infections, this is calamitous infringement for patient; Again, prosthese extends through operation and realizes, and operation completes the short period of time, and within the relatively short time, limbs carry out the growth of more than 3cm, may cause patient vessel, nerve injury in this process, affect limb function.And the prosthese that automatically prolongs of our design allows limbs of patient to extend to carry out in careless motion every day.
Therefore, developing a kind of prosthese that can automatically extend being applicable to child patient is an important research contents in art.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide a kind of prosthese that can automatically extend. Prosthese of the present invention is mainly used in having the sufferer of growth needs, and such as children, along with the growth of patient age, the prosthese of the present invention can extend automatically, avoids pediatric tumor to protect limb patient and again performs the operation.
The prosthese that can automatically extend of the present invention is according to minimum fixation pressure floor (such as weight in patients), frequency change (walking or the motion frequency) and/or time variations, the extendable portion of prosthese is automatically prolonged, reaches the object of limbs growth.
Specifically, the prosthese that can automatically extend of the present invention comprises prosthese, middle transition part and lower prosthese, described upper prosthese or/or lower prosthese arrange prolongation device, especially, also arrange physiological data collection device at upper prosthese or lower prosthese, energy storage device, puopulsion unit and motor;
According to the data that physiological data collection device gathers, motor utilizes the energy of energy storage device, acts on puopulsion unit, and puopulsion unit advances, according to the track of setting and frequency, the prolongation device being arranged on upper prosthese and/or lower prosthese, to reach the effect extending limbs.
Wherein, described physiological data collection device is one or more in pressure sensitive device, timing device and counting mechanism;
Described energy storage device can be power supply or kinetic energy apparatus, as flown, in lithium ion battery, button cell or spring assembly, wrist-watch, the energy storage device etc. that sticks together;
Described puopulsion unit is used for advancing the extendable portion of prosthese according to setting means, thus prosthese and/or lower prosthese are increased relative to middle transition part, reaches the object that body increases, can be the mode such as slide rail, screw thread;
Described motor can select micro electric machine.
Further, owing to the growth needs of limbs changes according to age difference, so the propelling frequency of described puopulsion unit can according to the change of age of patient.
Concrete design variable can be formulated with reference to China's adolescent growth development index, such as children and youth height, body weight percentiles table (reference: China's paediatrics magazine, 7 phases in 2009).
Above-mentioned automatic elongation should be set as stopping after the growth period terminates.
Further, the described prosthese that can automatically extend also comprises time-out extension apparatus.
Described time-out extension apparatus mainly in order to control the carrying out of extension automatically further, owing to the growth of child also has stage, for the automatic growth mode at the uniform velocity set, sometimes may deviate the growth curve of child's reality. Therefore, the present inventor proposes to arrange time-out growing apparatus on the prosthese automatically extended, and described time-out growing apparatus arranges power-supply controller of electric on physiological data collection device or motor.
Further, described prolongation device is also provided with stop means, just fixes up/down prosthese after being stretched to length-specific, stop means can be set according to the length (such as 10-80mm) of the clinical restriction of doctor, after extension reaches this stop means, prosthese automatically locks, and no longer continues to extend. The concrete length limited needs doctor to carry out general assessment according to the height of infant father and mother.
Further, it is preferable that physiological data collection device is set at upper prosthese, energy storage device, puopulsion unit and motor.
Further, described physiological data collection device is one or both in timing device and counting mechanism.
Further, described energy storage device can be power supply;
Described puopulsion unit is slide rail, engagement thread;
Miniature motor selected by described motor.
Further, described physiological data collection device is counting mechanism.
Further, the described prosthese that can automatically extend also comprises time-out extension apparatus, and described time-out growing apparatus arranges power-supply controller of electric on physiological data collection device or motor.
Now electric energy is used for counting step number, and such family members control the speed of growth automatically by control power panel. Such as family members feel that suffering limb growth is too fast, it is possible to stop metering step number by powered-down mode, thus reach the effect that prosthese does not extend. Prosthese itself extends then dependence theory of machines completely and carries out, and can exempt many interference like this, and the electromagnetism occasion etc. that such as comes in and goes out causes prosthese obstacle. Because step number metering multiple spot is put less can not affect prosthesis function.
For this reason, the present inventor provides a kind of prosthese that can automatically extend further, and to count the prosthese that mode controls automatically to extend, by the startup of counter controls motor, motor drives transmission decelerating device, drives the extension of prosthese, adapts to the growth of human body.
