Description

A kind of dual-wavelength laser treatment prostatic hyperplasia equipment

Technical field

This utility model is the equipment about laser therapy, and it is specially adapted to suffering from the operative treatment of diseases such as prostatic hyperplasia, tumor of prostate and urologic neoplasms.

Background technology

The optimum loose disease of prostate (be called for short BPH) is the chronic hypertrophy of a kind of non-inflammatory, can cause that urinary tract is narrow even blocks, gradual can not spontaneous recovery, the about BPH that suffers from more than 10% in various degree of male more than 50 years old is puzzlement middle-aging male crowd's a common frdquently encountered disease.

Therapeutic purposes are the prominent hypertrophy prostata tissues to urethra of excision, enlarge urethra, and it is unobstructed to recover urinary tract.Therapeutic Method mainly comprises TURP method and laser therapy.Wherein, TURP method excision prostate speed is very fast, but exist operating difficulty big, hemorrhage many, easily produce shortcoming such as complication.Laser therapy mainly comprises iraser and green laser therapy.Wherein, iraser has been used for the BPH treatment since the eighties in last century, brought into play certain effect.Because the BPH treatment needs to carry out under the condition of water-filling, and iraser is relatively poor to the penetrance of water, must press close to tissue to vaporize, the wayward tissue necrosis degree of depth, haemostatic effect is poor, so far not seen widespread use.The beginning of this century state extrapolated the green laser BPH minimally-invasive treatment machine of output mean power 80W, because green laser is high and easily be organized absorption to the transmitance of water, therefore use that green laser therapy BPH has that method is easy, instant effect, go out insufficiency of blood, curative effect lasting time is long, the advantages such as number of days is few of being in hospital, but only adopt green laser ablation prostate, postoperative disappearance tissue surface is bigger, and wound repair needs day longer, has increased the danger of secondary hemorrhage or secondary infection.

At present, the used light source of iraser therapy equipment mainly contains 808nm semiconductor laser light resource, 1064nm Nd:YAG LASER Light Source, 2100nm Ho:YAG LASER Light Source etc.The used light source of green device for laser therapy is mainly and adopts Nd:YAG frequency multiplication 532nm laser etc.

The utility model content

In order to overcome above-mentioned shortcoming, the utility model proposes following technical scheme:

A kind of dual-wavelength laser treatment prostatic hyperplasia equipment comprises a green laser and an infrared laser, is used for providing complete machine at the required LASER Light Source of therapeutic process; Master control system by microcomputer and electronic actuators part thereof, electronic sensor constitute is used to control whole laser therapeutic system; Bundling device is used for green laser and these two kinds of different wavelength of laser light beams of iraser are merged; Optical gate is used for discharging or closing laser beam; Photo-coupler is used to improve beam quality; Fiber coupler is used for light beam coupling is advanced optical fiber; Light is used to import light into human body; Endoscope is as the additional device of optical fiber importing human body; Display system is used to show the demonstration of whole therapy system ruuning situation; Gauge tap is used for manually controlling the Push And Release of optical gate; The endoscopic images display system is used for the real-time demonstration of operation process; Recording system is made of computer system, is used for the real time record operation process.

Wherein:

The green laser average output power is 80 to 180 watts, its laser instrument can be made of following laser instrument: the Nd:YAG frequency double laser, the Yb:YAG frequency double laser, the Nd:YVO4 frequency double laser, the Nd:GGG frequency double laser, the Nd:YLF frequency double laser, Nd:YAP frequency double laser, Nd:S-FAP frequency double laser, the Yb:GGG frequency double laser, the Yb:YLF frequency double laser, Yb:YAP frequency double laser, Yb:S-FAP frequency double laser, mix Nd ion glass frequency double laser, mix Yb ion glass frequency double laser, mix Nd ion pottery frequency double laser, mix Yb ion pottery frequency double laser, mix the optical fiber frequency double laser of Nd, mix the optical fiber frequency double laser of Yb, argon ion laser, copper-vapor laser;

The infrared laser average output power is 50 to 80 watts, can be made of following infrared laser: Nd:YAG laser instrument, Yb:YAG laser instrument, the Nd:YVO4 laser instrument, Nd:GGG laser instrument, Nd:YLF laser instrument, the Nd:YAP laser instrument, Nd:S-FAP laser instrument, Yb:GGG laser instrument, the Yb:YLF laser instrument, the Yb:YA laser instrument, Yb:S-FAP laser instrument, Er:YAG laser instrument, the Ho:YAG laser instrument, the Tm:YAG laser instrument is mixed Nd ion amorphous laser, mixes Yb ion amorphous laser, mix Nd ion ceramic laser, mix Yb ion ceramic laser, mix the optical fiber laser of Nd, mix the optical fiber laser of Yb, mix the optical fiber laser of Er, semiconductor laser.

The BPH treatment needs to carry out under the condition of water-filling.Only adopt iraser treatment BPH, iraser is relatively poor to the penetrance of water, and must press close to tissue and vaporize, the wayward tissue necrosis degree of depth, haemostatic effect is poor, can't extensive use.Only adopt green laser therapy BPH, green laser is high and easily be organized absorption to the transmitance of water, therefore use green laser therapy BPH to have that method is easy, the gasification excision is fast, go out advantage such as insufficiency of blood, but only adopt green laser therapy BPH can not accomplish the effect of solidified structure, defectiveness still aspect the normal condition of recovery organization as early as possible.

Therefore, the purpose of this utility model is the defective that overcomes above-mentioned prior art, adopts dual-wavelength laser (green laser and iraser) treatment BPH, makes it to have concurrently the treatment advantage of green laser and iraser, and abandon separately shortcoming, realize better therapeutic effect.Promptly adopt green laser ablation body of gland, have that method is easy, gasification excision fast, go out advantage such as insufficiency of blood, adopt simultaneously iraser to tissue solidify, fibrosis, the normal condition of recovery organization as early as possible, reduce the danger of secondary infection and complication, play an important role for postoperative rehabilitation.

In this utility model device, can export the green laser and the iraser of high-average power at the same time or separately, make it to have concurrently the treatment advantage of green laser and iraser, and abandon shortcoming separately, realize better therapeutic effect.Promptly adopt green laser ablation body of gland, have that method is easy, gasification excision fast, go out advantage such as insufficiency of blood Wicresoft, adopt simultaneously iraser to tissue solidify, fibrosis, the normal condition of recovery organization as early as possible, reduce the danger of secondary infection and complication, play an important role for postoperative rehabilitation.Therefore, adopting dual-wavelength laser treatment BPH will be a kind of Perfected process.And owing to there are two kinds of wavelength lasers to close bundle output, choice of operative methods will increase greatly, can adapt to more disease, removes art etc. as tumor.
