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.

A system for minimizing leakage of fluid distending media by the sides of the endoscopic instrument in endoscopic procedures such as arthroscopy, hysteroscopy or laparoscopy. A double-wall flexible tubular sheath having walls containing pressurized fluid is mounted over an endoscopic instrument. The double-wall flexible tubular sheath moves in and out of a natural opening of a tissue cavity or through an incision made in the cavity wall.

The invention relates to medical equipment, in particular to a hysteroscope water leakage prevention device, comprising a transparent film that can be pasted on the vulva, a hysteroscope operating support is arranged at the center of the transparent film, and a hysteroscope is arranged in the middle of the operating support The operation hole is equipped with a rubber plug for sealing the hole, and the rubber plug can be inserted into the uterine cavity through the operation support after being sealed and sleeved on the hysteroscope. The transparent film of the present invention can cover the areas around the labia majora, the vaginal opening and the posterior junction of the perineum, an operating support is arranged in the middle of the film, and the rubber stopper matched with the support can be placed with a hysteroscope with an outer diameter of 4-10 mm. The hysteroscope is sealed with the rubber plug, and the rubber plug is sealed with the support, so it will not cause leakage of the uterine distended fluid, and the rubber plug will not affect the free entry and exit of the hysteroscope body into and out of the hymen hole.

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.

A device for visualization of internal tissue of a patient's uterus having a hand-held control unit, an elongated member, and an image capturing tip. To increase the manoeuvrability of the image capturing tip, the elongated member forms a straight portion extending along a straight axis and a curved portion forming a curvature away from the straight axis, the curved portion being between the image capturing tip and the straight portion. By rotation of an inner tube in an outer tube, the image capturing structure will move along a circular path without being rotated about the centre axis of the elongated member.

The invention relates to an adjustable angle hysteroscope comprising a handle, a probe, a bend, an insert tube, a light-emitting member and an angular adjusting part. The adjustable angle hysteroscope is characterized in that the bend connects the probe and the insert tube; an optical fiber and an image transmission line are provided within the insert tube, the bend and the probe; the probe is disposed at the front end and is internally provided with a lens; the light-emitting member is disposed within the handle; the angular adjusting part comprises a thin wire, a rotary structure and a control structure, one end of the thin wire is connected to the probe, the other end thereof is connected to an electric machine arranged within the handle, the rotary structure is disposed on the handle, and the control structure controls the rotary structure to rotate; the electric machine is used for adjusting length of the thin wire; the electric machine disposed on the rotary structure can rotate with a turnplate. During using, by adjusting the length of the thin wire and rotating the rotary structure, the front angle of the adjustable angle hysteroscope can be adjusted so as to examine the uterus in all directions; operating is simple, and using is convenient.

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.
