Technical Field

The invention relates to the technical field of medical auxiliary instruments, in particular to a uterine cavity dilator.

Background

The field of the gynecological operation requiring the use of the expansion of the uterine cavity is very wide, such as the hysteroscopy uterus expansion, the operation after the uterine cavity adhesion separation operation, or the orthophoria abortion, the uterine cavity examination operation and the like which can be really realized in the future, and the existing uterine cavity expansion has the following problems:

1. the traditional hysteroscope requires a liquid medium or a gas medium for uterus expansion, certain clinical complications exist, and the life is seriously threatened;

2. the tumor-free principle of tumor resection at present makes tumor resection under a laparoscope controversial, hysteroscopes are well known, a uterine cavity, an oviduct and a pelvic cavity are physiological channels, uterus is an organ with rich blood flow, a uterine swelling medium easily enters an abdominal cavity through the oviduct or directly enters systemic circulation through uterine swelling pressure, and by the same reason, under the condition that the uterine cavity canceration and the endometrial canceration are unknown, cancer cells are probably spread away through the uterine swelling medium.

3. The artificial abortion, the visual artificial abortion and the visual artificial abortion with microtubules can not be directly observed to take out the chorion of the pregnant sac.

Disclosure of Invention

In order to solve the technical problems in the prior art, such as the above technical problems, the present invention discloses a uterine cavity dilator, comprising: the device comprises a fixed pipe, an opening, a spring plate, a chute and a driving pipe;

the fixing tube is provided with an opening along the length direction, through holes are respectively formed in the inner parts of the two sides of the opening along the length direction, the two ends of the elastic sheet respectively penetrate through the fixing tube through the through holes, sliding grooves are symmetrically formed in the outer wall surface of the fixing tube, and the driving tube is slidably arranged in the sliding grooves and connected with the two ends of the elastic sheet so as to drive the elastic sheet to slide in the through holes;

preferably, the driving pipe is semicircular, and the inner radius of the driving pipe is the same as the outer radius of the fixed pipe.

Preferably, the driving pipe is connected with two ends of the elastic sheet through fixing blocks.

Preferably, the driving pipe is made of elastic material.

Preferably, scales are arranged on the outer wall surface of the fixed pipe between the driving pipe and the opening.

The invention provides a uterine cavity expander. The method has the following beneficial effects: through setting up the shell fragment in fixed intraductal, can drive the shell fragment through the drive tube and remove, the shell fragment supports to both sides under self elastic action, expand the palace chamber, hysteroscope accessible opening is deepened to the palace chamber simultaneously, is convenient for to the observation of operation process, this device simple structure, convenient to use need not the uterus swelling medium and can avoid the medium to lead to the pulmonary edema or complication such as air embolism of perfusion fluid excess absorption syndrome, provide safer operation guarantee for patient's operation.
