Description
Technical field
This utility model relates to the laser therapy technology, particularly a kind of medical multifunctional device for laser therapy.
Background technology
The energy of laser is high concentration on time, space, spectrum, and it is widely applied in various fields.Wherein, medical science be applicating laser technology the earliest, a most extensive and most active subject.Countries in the world have been developed the laser medical equipment of the different therapeutic use of many kinds, and for clinical treatment.
Current, the purpose that reaches cure diseases with minimum wound has become the trend that international surgical field develops, traditional operative model is constantly eliminated by novel Wicresoft's intervene operation, and Wicresoft's interventional therapy has become one of Main Means of modern hospital clinical treatment.Modern micro-wound surgical operation needs advanced naturopathy core technology as support, and has become the core competitiveness of the emerging strategic industry of medical apparatus and instruments with sustainable development feature.Various naturopathy means implement to treatment target surgical procedure such as excising, melt, realize the purpose of minimally-invasive treatment.
Continuous renewal and development along with technology, the continuous expansion of indication therapeutic domain, clinical operation requires more and more diversifiedly to medical apparatus and instruments, and at present the laser operation equipment of simple function can not meet the special requirement of each process of surgical operation, can not obtain optimum therapeutic effect.
For the needs people that further meet clinical operation start the laser operation equipment of various functions is further studied, the device for laser therapy that is applied at present the difference in functionality in medical treatment has:
The green laser tissue vapourizing unit of 532nm wavelength of 1, performing the operation for Urology Surgery, neurosurgery etc., green laser tissue vapourizing unit is at the treatment prostatic hyperplasia, have without sexual impotence, need not plug in catheter, postoperatively do not need the advantages such as Long-term taking medicine, Comprehensive Treatment expense be low, in the U.S., become outpatient operation.The concrete principle of its generating device of laser is: the 532nm wavelength laser is by semiconductor laser (LD) L1; Pumping neodymium-doped yttrium-aluminum garnet (Nd:YAG) crystal a, form 1.06 μ m laserresonators by laser Effect of Back-Cavity Mirror M1 and outgoing mirror M2, in resonator cavity, add KTP frequency-doubling crystal A, harmonic wave mirror M3 and acousto-optic modulator D to produce by 1.06 μ m laser freuqency doublings, as shown in Figure 1.
2, for the tissues such as human liver, kidney being carried out to the Nd:YAG laser aid of 1.06 mum wavelengths of cutting operation, 1.06 mum wavelength Nd:YAG laser carry out human body kidney Partial Resection and remove and compared hemorrhage obvious minimizing with conventional cold cut, and operating time shortens.High power 1.06 mum wavelength Nd:YAG laser aids can cut the hepatic tissue of sclerosis, can be by cancerous protuberance local excision to the hepatocarcinoma with heavier liver cirrhosis.It excites the concrete principle of generating apparatus to be: 1.06 mum wavelength laser are by semiconductor laser (LD) L2; Pumping neodymium-doped yttrium-aluminum garnet (Nd:YAG) crystal b, form 1.06 mum wavelengths as shown in Figure 2 by laser Effect of Back-Cavity Mirror M4 and outgoing mirror M5.
3, to the Nd:YAG laser aid of 1.32 mum wavelengths with tissue is stopped blooding, 1.32 mum wavelength can solidify the formation thrombosis to vessel inner blood, reach good haemostatic effect, can solve in routine operation the patient because of the hemorrhage complication to causing excessively, to patient's healthy and physical recovery, provide assurance.It excites the concrete principle of generating apparatus to be: 1.32 mum wavelength laser are by semiconductor laser (LD) L3; Pumping neodymium-doped yttrium-aluminum garnet (Nd:YAG) crystal c, form 1.32 mum wavelength Laser outputs as shown in Figure 3 by laser Effect of Back-Cavity Mirror M6 and outgoing mirror M7.
