Detailed Description

In order to clearly illustrate the technical features of the present solution, the present utility model will be described in detail below with reference to the accompanying drawings.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1-3, the hysteromyoma stripping device comprises an umbrella-shaped head 1 and a stripper matched with the umbrella-shaped head, wherein the center of the top end of the umbrella-shaped head is provided with a smooth convex surface in a cylindrical head shape, the side wall of the front side of the umbrella-shaped head is provided with a notch 2, the outer edges of the two sides of the notch are arranged in a curve, and the notch is gradually reduced from the outer edge of the umbrella-shaped head to the opening of the central direction of the umbrella-shaped head; a first supporting rod 3 is fixedly connected to the lower portion of the rear side wall of the umbrella-shaped head corresponding to the notch, a sleeve 4 is fixedly sleeved on the outer side of the first supporting rod below the umbrella-shaped head, a second supporting rod 5 is movably arranged in the sleeve up and down, the second supporting rod corresponds to the center of the umbrella head of the umbrella-shaped head, the top end of the second supporting rod penetrates out of the top end of the sleeve 4 and is connected with the stripper through an L-shaped connecting rod 6, and the bottom end of the second supporting rod penetrates out of the sleeve and is fixedly connected with a curved-moon-shaped cambered surface handle 7.

The stripper comprises a stripping knife 8 which is arranged in a cambered surface knife capable of freely rotating along the circumferential direction with the umbrella-shaped head, and the top end of the L-shaped connecting rod is connected with the middle part of the bottom wall of the cambered surface knife. When the cambered surface knife is driven to rotate to the notch position of the umbrella-shaped head through the second supporting rod, the notch along the radial length direction of the side wall of the umbrella-shaped head can be covered. Thus, along with the rotation of the cambered surface knife, when the umbrella-shaped head is properly inclined, the hysteromyoma surrounded by the notch of the umbrella-shaped head can be gradually cut and peeled by the cambered surface knife, and in the process, the umbrella-shaped head is attached to the surface of the uterine wall outside the hysteromyoma, so that the traction of the stripper on the tissue of the uterine wall outside the hysteromyoma is avoided in the cutting and peeling process, and the operation trouble caused by large bleeding amount is avoided.

The opening angle of the narrower end of the notch 2 is set to 120 °. One end of the narrow opening of the notch is lower than the top end of the umbrella head of the umbrella-shaped head. Therefore, when the umbrella-shaped head peeling knife is used, especially when the peeling knife and the umbrella-shaped head are matched to move and peel and cut, the umbrella-shaped head can be inclined and moved by taking the umbrella head as the center, and potential damage to the uterine wall is avoided in the process.

When the cambered surface knife contacts with the inner side wall of the umbrella-shaped head and rotates around the second supporting rod 5 as the center along the circumferential direction of the inner side of the umbrella-shaped head, the side wall of the umbrella-shaped head can completely prevent the cambered surface knife from being protected, namely the length of the cambered surface knife does not exceed the outer edge of the umbrella-shaped head, and thus, the cambered surface knife gradually peels off hysteromyoma at the notch position. The umbrella-shaped head is matched with the cambered surface knife to finish hysteromyoma peeling, and the peeler is protected from entering the uterine cavity.

The diameter of the outer edge of the bottom edge of the umbrella-shaped head is 1.5cm, the height of the umbrella-shaped head is 1.5cm, and the length of the sleeve is 17cm; the sleeve is arranged at one end close to the umbrella-shaped head and is lower than the bottom edge of the umbrella-shaped head, so that a certain movable distance is provided for the cambered surface knife along the height direction of the umbrella-shaped head, and the stripping operation is more flexible.

The bottom of the side wall of the sleeve is provided with a concave holding part 9 according to the hand holding habit, and the concave holding part is two shallow grooves which are arranged at the left side and the right side of the sleeve and are vertically arranged.

When in use, the sleeve 4 is held by hand, the stripping knife 8 is abutted against the umbrella-shaped head 1 through the curved-surface handle 7, so that the stripping knife avoids the notch 2 on the side wall of the umbrella-shaped head; the whole device is sent into a uterine cavity, uterine fibroids needing to be peeled off on the uterine wall are found through observation of a camera lens in an operation, an umbrella-shaped head is gradually sleeved on the outer edge of the bottom of the uterine fibroids from a notch position, then a sleeve 4 is held by a concave holding part 9 by one hand, a second supporting rod 5 is rotated by a curved-moon-shaped cambered surface handle 7 by the other hand, a peeling knife 8 is driven to rotate along the inner wall of the umbrella-shaped head, and at the moment, the side wall of the umbrella-shaped head is pressed against the uterine wall, so that the peeling knife is convenient to peel off; in order to better realize stripping, an operator changes the inclination direction of the umbrella-shaped head 1 through proper inclination of the sleeve, so that the umbrella-shaped head can flexibly grasp uterine fibroids at different positions on the uterine wall, and gradually strip the uterine fibroids from the uterine wall under the state of being attached to the stripping knife, thereby avoiding traction and injury to the uterine wall in operation. In the process, the second supporting rod can be pulled to realize the proper separation of the peeling knife and the inner wall of the umbrella-shaped head, so that the hysteromyoma can be peeled off circumferentially and simultaneously has a pulling and cutting force, and the peeling is easier.

The above embodiments are not to be taken as limiting the scope of the utility model, and any alternatives or modifications to the embodiments of the utility model will be apparent to those skilled in the art and fall within the scope of the utility model.

The present utility model is not described in detail in the present application, and is well known to those skilled in the art.
