Description

Skin laser treatment auxiliary robot and householder method thereof
Technical field
The present invention relates to a kind of important treatment auxiliary robot of medical domain, be specifically related to a kind of skin laser treatment auxiliary robot and householder method thereof.
Background technology
Along with the popularization of skin laser treatment, laser beautifying technology, the medical treatment of dermatological laser project is carried out in the current whole nation, the mechanism that improves looks reaches 98.3 ten thousand.From technical merit, laser beautifying treatment is basic based on manual operations, at the bottom of automaticity, high to the dependency of laser therapy doctor.And doctor's number of every thousand people of China is only 0.79 of Japan, be only the half of Germany.People constantly increase this high-end technology demand of laser therapy, and corresponding high-quality laser therapy doctor extremely lacks, and it is extremely urgent that above-mentioned imbalance between supply and demand makes to research and develop a kind of laser therapy auxiliary robot that can substitute or improve man efficiency.
Medical Robot obtains exploitation and drops into rapidly clinical practice starting from the beginning of 21 century, is considered to the revolution in medical development history.Medical Robot integrates the novel crossed research field of the subjects such as medical science, biomechanics, mechanics, Mechanics of Machinery, computer graphics, computer vision, mathematical analysis, robot, have a wide range of applications on dual-use, and Medical Robot field is study hotspot wherein.The medical robotic system of viable commercial product comprises both at home and abroad: Leonardo da Vinci's surgical robot system, domestic highly skilled man surgical operation robot etc.The dexterity manipulation that surgeon provides through it, precise positioning and preoperative planning, can make sufferer surgical wound reduce, postoperative rapid recoverys orthobiosis etc., reaches accuracy and invasive two advantage greatly.Current Medical Robot's R&D direction is mainly auxiliary intracavity operation, and for the research and development of external Medical Robot, especially carries out the medical robotic system of therapeutic procedure, is still in the blank stage both at home and abroad.
Medical Robot has many technical advantages compared with Traditional Man technology, have become more meticulous, high speed, intellectuality, Wicresoft feature, can diagnostic symptom more accurately, scientific analysis pathology, reduces manual operation error.Meanwhile, environment resistant interference, overcome the aspects such as patient's function limit, compared with manual operation, there is unrivaled advantage.Therefore, Medical Robot China's sustain economic high speed development enter higher level in must substitute the traditional artificial technology of a part.
At present, really there is the problem being difficult to as follows overcome in the skin laser treatment based on manual operation:
In clinical practice, qualified laser therapy teacher often needs to possess theory study for many years and practice experience, just can guarantee the effect of laser therapy.In special situation (as: not good, tired, the emotion of light, periphery interference etc.), even if human operational error also easily appears in veteran laser doctor, severe patient can cause Endodontic failure, even disfeature.
In laser therapy, dermatological laser equipment major part commercial is at present hand-held, and laser doctor must manually in execution operation, and whole-course treatment must ensure that laser probe is vertical with the surface of target site skin, constant distance; Meanwhile, during unenhanced treatment, after single laser pulse is launched, laser probe will move with constant space, to guarantee not leave over treatment dead angle.Pure manual operations is difficult to avoid producing deviation, causes overmedication, deficiency or uneven first-class defect, affects laser therapy effect to a certain extent.
Another important problem is that the ergonomics parameter designing of dermatological laser equipment is improper; Or reach a certain specific indexes for laser, and another index be associated exceedes the limit of manual control.As: the laser pulse frequency of pulse laser equipment is up to more than 30HZ (too low frequency may cause treatment time to extend, and patient tolerance declines, patient's fatiguability), the displacement limits frequency only 3HZ of staff.If ensure accurate displacement, the displacement frequency of staff also will decline greatly.In this case, doctor often with custom, can only sacrifice certain aspect advantage of laser therapeutic equipment, carries out the treatment of " human intervention formula ".
Therefore, from above-mentioned some, current laser therapy is the treatment of empirical formula, is difficult to ensure the standardization of laser therapy, and treatment is depended on " maneuver ", " anticipation " and " estimation " for the treatment of doctor, and curative effect is difficult to guarantee.
Intelligent Medical Robot has efficiently, accurately, at a high speed, the inherent advantage such as anti-interference, parameter threshold is adjustable.Therefore, the exploitation of science also reasonably designs laser therapy machine people aid system, contributes to " bottleneck " difficult problem solving above-mentioned several long-standing problem laser therapy.

9) as another kind of multi-degree-of-freemechanical mechanical arm formula mobile robot, by specific algorithm, the movement locus of the end actuating unit of multi-degree-of-freemechanical mechanical arm formula mobile robot is planned, driven the motion of therapeutic instrument laser probe by end actuating unit; Mechanical arm initiating terminal and bearing adopt guide rail to be connected;
10) carrying out in skin treating process, if patient have many places different parts need treatment, at least two multi-degree-of-freemechanical mechanical arm formula mobile robots can be adopted to treat it simultaneously, effectively improve therapeutic efficiency.
