Description

Technical Field

[0001] The invention relates to medical device technology, and in particular to an angiography auxiliary device used in an imaging department. Background Art

[0002] Contrast examination usually follows the steps of preparation, positioning guidance, contrast agent injection, image acquisition, observation and diagnosis. Hysterosalpinography (HSG) has been used since the 1920s. It is a method of injecting iodine, a high-density substance composed of a high atomic number, into the uterine cavity through the cervical canal. Under X-rays, it forms a clear artificial contrast with the surrounding tissues, allowing the lumen to be visualized, so as to understand the situation in the uterus and fallopian tube cavity. Contrast examination can not only indicate whether the fallopian tube is unobstructed and the location of obstruction, but also observe the morphology of the uterine cavity. This examination is relatively safe, does not require anesthesia, is not obviously painful, and can be accepted by patients.

[0003] The Chinese invention patent with the authorization announcement number CN114306887B discloses a hysterography examination auxiliary device with a hose auxiliary support and an implementation method thereof. The hysterography examination auxiliary device with a hose auxiliary support and the implementation method thereof manually press the pressing pieces of the first clamping component and the second clamping component at the same time to rotate and open the connection cover, and then pass the supporting hard tube between the first clamping component and the second clamping component, and then release the pressing piece. Under the cooperation effect of the first extrusion spring and the second extrusion spring, the supporting hard tube is clamped and the direction of the supporting hard tube is fixed. After clamping, it is also convenient to control the supporting hard tube to push forward later. The clamping is stable and not easy to slide. It solves the problem that the current hose for hysterography examination conveys liquid by manually fixing the conveying part, the manual support operation is troublesome, the swing amplitude is large, the cervix will contract, and the hose will be pushed out due to the contraction of the internal organs when the examination or injection of the drug is not fixed. However, when performing hysterography, some patients have a tight cervical opening, which increases the difficulty when inserting the contrast fluid catheter, and requires a uterine dilation operation, which increases the steps of the contrast and reduces the speed of the contrast.

[0033] The uterine expansion mechanism 3 is used to expand the external cervical os of the patient. The uterine expansion mechanism 3 includes a covering 31, a driving assembly and multiple expansion assemblies. The multiple expansion assemblies are arranged in a circular array with the axis of the A support sleeve 21 as the center. The expansion assembly includes a push plate 32, a mounting plate 33 and a tension spring 34. One side of the mounting plate 33 is fixedly connected to the A support sleeve 21, and both sides of the bottom end of the push plate 32 are rotatably connected to the mounting plate 33 through a rotating shaft. The side of the push plate 32 close to the A support sleeve 21 is fixedly connected to the tension spring 34, and the end of the tension spring 34 away from the push plate 32 is fixedly connected to the mounting plate 33. One side of the push plate 32 is connected to a driving assembly for driving it to rotate around the axis of the rotating shaft. The covering 31 is used to cover multiple expansion assemblies.

[0034] When performing uterine radiography, some patients have tight cervical os, which increases the difficulty in inserting the contrast fluid catheter and requires uterine dilation operation, which increases the steps of radiography and reduces the speed of radiography. For this reason, a uterine dilation mechanism 3 is provided, and the driving component drives the push plates 32 in the multiple expansion components to rotate around the axis of the rotating shaft. Since the multiple push plates 32 are arranged in a circular array with the axis of the A support sleeve 21 as the center, the multiple push plates 32 rotate to expand the cervical os, and under the covering of the covering member 31, the push plates 32 are prevented from directly contacting the inner wall of the cervix, thereby reducing the patient's pain. After the patient's cervical os is expanded, the medical staff pushes the catheter 1, and under the restriction of the A guide member, the catheter 1 moves along the axial direction of the A support sleeve 21, so that the catheter 1 is inserted into the patient's uterus, thereby improving the radiography efficiency.
