Embodiment Construction

[0014] refer to figure 1 and figure 2 , the present invention is composed of an outer sheath 1, an inner sheath manipulator 2, a mirror body 3, and instrument forceps 5. The inner sheath manipulator 2 includes an instrument valve 6, an arc connecting pipe 7, a mirror body channel 8, an instrument channel 10, etc. part. During the operation, the outer sheath tube 9 in the outer sheath 1 is the insertion part, and is connected with the inner sheath manipulator 2, mirror body 3, camera bayonet 4 and other components through a locking structure to form a complete set of surgical equipment. The instrument forceps 5 completes the operation under the microscope through the instrument channel 10 . The design of the novel hysteroscope teardrop-shaped outer sheath tube 9 avoids increasing the pain caused by dilation of the uterus to the patient. The instrument channel formed by the instrument forceps 5 through the instrument valve 6 and the arc connecting pipe 7 is more conducive to...

Abstract

The invention relates to a minimally invasive hysteroscope which is a uterus-expansion-free hysteroscope with an operative instrument passage convenient for operation. The minimally invasive hysteroscope is designed to avoid uterus expansion and facilitate doctors' operation when a hysteroscope operation is performed. Thus, the minimally invasive hysteroscope is characterized in that a special tube, namely a teardrop-shaped catheter sheath, serves as an outer catheter sheath, and the instrument passage is connected with an instrument valve through an arc transition passage.

Description

technical field [0001] The invention relates to a minimally invasive hysteroscope, which is a dilatation-free hysteroscope with an easy-to-operate surgical instrument channel. Background technique [0002] At present, in minimally invasive surgery, the scope sheath of hysteroscope is mostly a circular tube. After the sheath passes through the scope and instruments during the operation, there is still room for invalid operation. The outer diameter of these sheaths is relatively large, and during hysteroscopic surgery, the patient needs to undergo a large dilatation of the uterus. At the same time, conventional hysteroscopes have the problem of being inconvenient to operate when using instrument forceps. Contents of the invention [0003] In order to avoid dilating the uterus during hysteroscopic surgery and facilitate the doctor's operation, the present invention proposes a new type of non-dilatation hysteroscope with an easy-to-operate surgical instrument channel. The ...
