A hysteroscopy system includes a scope having an internal channel, a sheath removably coupled to the scope, and an outflow channel. The sheath has a distal flange extending internally towards an outer surface of the scope. The outflow channel is formed between an inner surface of the sheath and an outer surface of the scope. The distal flange forms a distal end of the outflow channel and is generally located between the scope and the sheath.

The invention belongs to the medical instrument and particularly relates to a novel three-dimensional electronic hysteroscopy system reconstructed by using multiple CCD (Charge-Coupled Device) arrays. The novel three-dimensional electronic hysteroscopy system comprises a soft electronic hysteroscopy consisting of a soft sheath, a sheath section core and a hysteroscopy main body and also comprisesa processing host machine, a light source host machine and a workstation assembly which are connected with the soft electronic hysteroscopy; the soft electronic hysteroscopy enters a uterine cavity through the soft sheath; the uterine cavity is finely scanned by the multiple CCD array modules at the forefront part of the work end part of the hysteroscopy of the hysteroscopy main body to obtain a three-dimensional image which is used for a doctor to treat the intrauterine lesions.

The invention discloses a hysteroscope system based on optical coherence tomography and an implementation method of the hysteroscope system. The hysteroscope system based on the optical coherence tomography comprises a hysteroscope body, an optical coherence tomography module and a tomography host. Compared with an existing hysteroscope, the hysteroscope system based on the optical coherence tomography can achieve the ordinary white light tomography mode and the depth tomography mode at the same time; information of tissue structures in the uterus epidermis with the depth ranging from 2mm to 3mm can be provided by depth tomography, the early cancer existing under the skin can be detected, and an important means is provided for early disease diagnosis of the uterus cancer; in addition, due to the fact that an infrared broadband light source is adopted, the tomography depth can range from 2mm to 3mm. Due to the fact that a wide-field interference mode is adopted, a tomography light guide which is provided with a scanning unit and needed by an ordinary optical coherence tomography technology is simplified, an existing commercially available tomography fiber optics bundle can serve as the tomography light guide, a probe does not need to be designed, production is easy through the design, and the hysteroscope system based on the optical coherence tomography has the good market promotion and application prospect.

The invention discloses a multi-mode hysteroscope system and an obtaining method of the multi-mode hysteroscope system. The multi-mode hysteroscope system comprises a main hysteroscope body, an optical coherence tomography module, a co-focus imaging module and an imaging main unit. Compared with an existing hysteroscope, the multi-mode hysteroscope system has the advantage that ordinary white-light imaging, deep tomography and subcellsular level imaging can be achieved at the same time. The structural information of tissue within the depth range of 2 mm-3mm of the uterus epidermis can be provided through deep tomography based on the traditional white-light surface layer micro-imaging with the resolution ratio of 10 microns, early-stage hypodermic canceration can be detected, imaging with the high resolution ratio of 200 nm can be conducted on the epithelial layer of the mucosa through subcellsular level imaging, and canceration of a single cell can be detected accurately. According to the multi-mode hysteroscope system and the obtaining method of the multi-mode hysteroscope system, an important means is provided for early screening of metrocarcinoma, and the multi-mode hysteroscope system has broad application and market popularization prospects.
