[ detailed description ] embodiments

The following description of the present invention is provided to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention and to make the above objects, features and advantages of the present invention more comprehensible.

Referring to fig. 1-4, the present invention provides a liquid leakage prevention hysteroscope 100, which comprises an air bag 10, a ball head 20 and a scope shaft 30.

The air bag 10 comprises a flexible outer wall 11 and a flexible inner wall 12 which is matched with the flexible outer wall 11 to form a closed cavity, and pressurized gas is filled in the closed cavity. The whole airbag 10 is in a sphere-like shape or an ellipsoid-like shape, and the outer surface of the flexible outer wall 11 is an arc-shaped curved surface. The flexible outer wall 11 and the flexible inner wall 12 are integrally processed and formed by rubber, silica gel or latex materials.

The flexible inner wall 12 includes a first portion 121 and second portions 122 disposed at two ends of the first portion 121, the first portion 121 defines a first cavity 123, the second portion 122 defines a second cavity 124, the number of the second cavities 124 is two, the first cavity 123 communicates with the two second cavities 124, and an opening of the second cavity 124 gradually increases toward a direction away from the first cavity 123. Two of the second portions 122 are symmetrically disposed about the first portion 121.

When the inflatable uterus-expanding liquid bag is used, the air bag 10 is attached to the vaginal opening, the vaginal opening is sealed after the air bag 10 is inflated, the uterus-expanding liquid can be prevented from leaking out of the vaginal opening, meanwhile, the gas pressure in the air bag 10 can be adjusted, the deformation degree of the air bag 10 is changed, and different compression degrees are achieved.

Further, an inflation interface 13 is arranged on the air bag 10, and the inflation interface 13 is communicated with the closed cavity and the outside. Preferably, the inflation port 13 is disposed within the second lumen 124 to avoid direct contact with the patient. In use, the end of the air bag 10 provided with the inflation interface 13 faces the outside of the patient. The inflation interface 13 is used for inflating the air bag 10, and the inflation interface 13 can also be directly communicated with an external inflation device, so that the inflation operation can be conveniently and rapidly carried out, and the air pressure can be conveniently adjusted.

The ball head 20 is received and retained in the first cavity 123, and the ball head 20 can rotate freely in the first cavity 123. The bulb 20 is provided with a through hole along the axis direction in a penetrating manner, and the bulb 20 is sleeved on the mirror rod 30 through the through hole. The outer surface of the ball head 20 is a smooth spherical surface, the shape of the inner surface of the first part 121 is matched with that of the outer surface of the ball head 20, and the outer surface of the ball head 20 is attached to the inner surface of the first part, so that liquid leakage is avoided.

It can be understood that the ball 20 can rotate in the first cavity 123, and the mirror rod 30 passes through the ball 20, so that the mirror rod 30 can also rotate to a certain extent with the ball 20 as a rotation center, and the second cavity 124 has a bell mouth shape, which just provides a space for the rotation of the mirror rod 30, and facilitates obtaining a larger view field. Preferably, the angle of the second portion 122 relative to the central axis of the balloon 10 is 30 ° to 75 °, which can enlarge the rotation angle of the mirror shaft 30.

Because the balloon 10 needs to be in direct contact with a patient and the ball head 20 does not need to be in direct contact with the patient, the ball head 20 can be selected to be a stainless steel ball head for repeated use, and the balloon 10 can be selected to be a disposable product and is discarded after each use. The first portion 121 has a certain elasticity, and before use, the ball head 20 is directly inserted into the first cavity 123, and then the mirror rod 30 is inserted through the through hole for use, and after use, the ball head 20 is taken out, and the airbag 10 is discarded.
