Description

TECHNICAL FIELD

[0001] The present application belongs to the field of laser medical technology, and particularly relates to a tool for treating diseases in a cavity, which is beneficial to guide an optical fiber into the cavity for implementation, such as treating reproductive disorders. BACKGROUND

[0002] Laser treatment technology, as an important field of physical treatment, has been applied in the field of gynecology and obstetrics for many years. Since Polanyi developed a CO2 laser suitable for gynecological and obstetrical applications in 1970, more than 30 kinds of gynecological and obstetrical diseases can be treated by various lasers at home and abroad. Now, lasers can not only diagnose gynecological and obstetrical diseases, but also treat various superficial diseases of the lower genital tract, such as the pelvic cavity, vulva, vagina and uterine cavity.

[0003] The mechanism of laser treatment is selective photothermolysis. After the laser energy is strongly absorbed by the target material (usually water, pigment and protein) in the tissue, the target tissue is coagulated and gasified, so as to realize non-contact treatment such as cutting, burning, gasification, coagulation and irradiation of the target tissue, while other tissues are not or less affected.

[0004] Common infertility, menstrual disorders, acute and chronic pelvic inflammatory disease, blocked fallopian tubes and endometriosis are all reproductive disorders. How to introduce a laser light source into the uterus for the treatment of reproductive disorders is still lacking effective tools. SUMMARY

[0005] In order to overcome the defects in the prior art, the purpose of the present application is to provide a laser hand tool for treating reproductive disorders, which is beneficial to guide a laser light source into the uterus for the treatment of reproductive disorders.

As Figure 1 ,Figure 2 and Figure 3 The laser handpiece for treating reproductive disorder diseases of the present embodiment, as shown in the figure, comprises a guide cylinder 10, an optical component and a treatment component.

[0041] The guide cylinder 10 comprises a body 15, a guide end 11, a connecting end 12 and a treatment opening 13, the connecting end is provided with a connecting opening 14, and the treatment opening 13 is provided on the side wall of the body 15 so that the two sides of the side wall are communicated. The optical component comprises a flat light-transmitting mirror 21 and a concave mirror 22, the flat light-transmitting mirror is provided at the treatment opening, and the concave mirror sends the received light towards the flat light-transmitting mirror.

[0042] The treatment component comprises a connecting seat 35, a first guide tube 31, a second guide tube 32, a third guide tube 33 and a fourth guide tube 34. The first guide tube 31 is arranged in the body 15, one end of which is fixed on the connecting seat 35; the second guide tube 32 is arranged in the body 15, one end of which is fixed on the connecting seat 35. The third guide tube 33 is arranged in the body 15, one end of which is fixed on the connecting seat 35, and the connecting seat 35 is assembled in the connecting opening 14 (such as tight fit, threaded connection or lock connection, etc.).

[0043] A first laser fiber is arranged in the first guide tube, the light wave emitted by the first laser fiber moves towards the concave mirror, is sent to the flat light-transmitting mirror through the concave mirror, realizes 90-degree change of the light path, leaves from the body 15 through the treatment opening, and irradiates on the diseased tissue of the patient, such as the diseased tissue on the side of the uterus. A second laser fiber is arranged in the second guide tube, the light wave emitted by the second laser fiber moves towards the concave mirror. The light wave emitted by the first laser fiber and the second laser fiber is different in wavelength. For example, the first laser fiber is 2-3 microns in wavelength, which is used for removing scars. The second laser fiber is 600-1100 microns in wavelength, especially 1064 microns, which is used for irradiating the tissue to implement treatment.

[0044] The fourth guide tube 34 is arranged in the body 15, one end of which is fixed on the connecting seat 35. A hysteroscope is arranged in the fourth guide tube, the viewing end of the hysteroscope is guided to the upper side of the flat light-transmitting mirror, which is used for real-time observation or obtaining image data.

[0045] Regarding the optical fiber, if the dot matrix light output is needed, the dot matrix optical fiber can be selected. If only irradiation or cutting is needed, the end of the optical fiber can not be processed as dot matrix; the light path is transmitted to the concave mirror by the optical fiber, is reflected to the light-transmitting mirror of the output window, so that

[0046] A disposable sterile guide cylinder is adopted, which is airtight, ensures the cleanliness of the light path, can avoid contamination of the liquid in the uterine cavity, and can be used once to avoid cross infection. For example,Figure 6 As shown, the treatment process, the leading end pushes away the mucosa, the treatment opening side wall scrape off the mucus, ensure that the laser energy 100% uniform effect to the uterine mucosa, and single use.

[0047] Figure 4 It is an embodiment of the present application for the schematic diagram of the dot matrix optical fiber. As shown Figure 4 The dot matrix optical fiber includes a single optical fiber 300, a collimating mechanism 200 and an ommatidium lens 100, and is placed in the pipe material, and is arranged along the axial direction of the pipe material. The ommatidium lens 100 is arranged at the output end of the single optical fiber 300, and the collimating mechanism 200 is arranged between the ommatidium lens 100 and the output end of the single optical fiber 300. The input end of the single optical fiber 300 is connected with a laser generator.

[0048] This embodiment realizes the dot matrix structure of light by the ommatidium lens, and the dot matrix structure can be realized on the end face of the optical fiber through an optical processing process, so that the structure is compact.

[0049] The fiber laser is used for generating a wavelength range of 600-3000 nm, and is not limited to an erbium-doped fiber laser and a thulium-doped fiber laser. The wavelength range of the erbium-doped fiber laser corresponds to 1.52-1.57 μm, and the radiation spectrum range of the thulium-doped fiber laser is relatively wide, covering a wavelength range of 1.6-2.1 μm.

[0050] The fiber laser includes an optical component device and a fiber connector. The optical component device includes a gradient reflectivity lens, a plano-convex lens and a plano-concave lens arranged in sequence. A laser beam of a pump source is coupled to a central axis of the fiber connector through the optical component device for output. Finally, the laser beam is transmitted to a uterine cavity scar for treatment through a multi-core optical fiber or a micro-lens array optical fiber or a side fiber via a hysteroscope.

[0051] The laser beam output by the fiber laser passes through the special fiber, including a dot matrix micro-lens array fiber laser. In addition, it can also be a side fiber output of a side light output laser, and the fiber material can be a silica fiber, a polymer fiber, a doped fiber and other fibers such as a biocompatible silk protein material.

[0052] Figure 5 It is a simulated schematic diagram of the light beam emitted by the fiber through the ommatidium lens array. As shown Figure 5As shown, the light rays output from the single optical fiber are collimated by the collimating mechanism, then incident on the fly-eye lens and form a dot array light by the fly-eye lens. The light array is thus dispersed in the local tissue, which helps to reduce the wound caused by the laser. When the laser is applied to the tissue in a dot array manner to form fine holes (0.2mm-0.5mm), three areas of micro-peeling, heat coagulation and thermal effect are formed in the tissue layer. A series of biochemical reactions of the tissue are then caused, so as to stimulate the tissue to accelerate self-repair. Since the scanning laser treatment only acts on a small fraction (usually only 1%-5%) of the tissue, the holes formed on the tissue do not overlap with each other, so that most of the normal tissue is preserved and the recovery is accelerated.

[0053] Compared with the conventional laser treatment device, the laser handpiece of the embodiment realizes the introduction of laser light into the uterus to achieve laser treatment of reproductive disorders. The introduction of two optical fibers with different wavelengths into the uterine cavity can implement treatment according to the actual situation of the uterine cavity, such as irradiation treatment and / or removal of scars, which is beneficial to the continuous development of the operation, reduces the frequency of replacement of the device, and shortens the implementation time of the operation.

[0054] By placing various optical fibers and hysteroscopes in the guide cylinder and changing the laser light path under the action of the light transmission mirror and the light reflection mirror, the treatment area accessible to the uterine cavity wall is expanded, so that the optical fiber can effectively implement laser treatment on the surrounding uterine cavity wall after entering the uterine cavity from the uterine orifice.

[0055] The optical fiber of the laser handpiece of the embodiment can be discarded as a disposable device after being used by the patient, and each optical fiber can be repeatedly used after being assembled with a new guide cylinder, so that the cost of the operation is greatly reduced, and the medical expenses are reduced.
