AI Technical Summary
When the hysterosalpingography (HSG) catheter is in an excessively anteflexed or retroflexed position of the uterus, it is necessary to use a dilator to repeatedly explore the uterine cavity, which can cause discomfort and pain to the patient.
A cannula-type hysterosalpingography (HSG) catheter is designed, with a rigid cannula at the front end to increase the rigidity of the catheter. After insertion into the uterus, the cannula is pulled out and expanded and fixed to avoid positional interference, thus achieving one-time catheter insertion.
It reduces patient suffering and the need for repeated sterilization of surgical instruments, and improves the convenience and success rate of the procedure.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of medical apparatus and instruments more particularly relates to a sleeve type uterine oviduct radiography pipe device. BACKGROUND
[0002] Uterine oviduct radiography is an imageological examination method for checking the shape, structure and function of uterus and oviduct, uterography injects high specific gravity material (such as iodine agent) composed of high atomic number into uterine cavity through cervix canal, then forms obvious artificial contrast with surrounding tissue under X-ray photography (or four-dimensional ultrasonic monitoring), makes lumen develop, thereby understands the situation in uterine and oviduct cavity, this method can clearly show the shape, structure of uterus and oviduct and the patency of oviduct.
[0003] For the position of excessive forward inclination of uterus (or excessive backward inclination of uterus), the conventional uterine oviduct radiography pipe (such as Figure 4 ) cannot reach the hardness, before the operation of radiography, the gynecologist needs to use appropriate dilatation rod to repeatedly probe the running of uterine cavity, changes the position of uterine cavity, in the process of probing, the patient will be uncomfortable, even painful. Based on the above problems, we provide a sleeve type uterine oviduct radiography pipe device.

[0006] The sleeve type uterine oviduct radiography pipe device provided by the utility model adopts the following technical scheme:
[0007] A sleeve-type hysterosalpingography tube device comprises a tube; a sleeve arranged at the front end of the tube and used to increase the hardness of the front end of the tube to facilitate the placement of the tube in the uterus. The sleeve is placed at the front end of the tube made of original silicone material, and then the silicone tube and the sleeve are passed into the uterus. Since the sleeve is equipped with a hard sleeve, it is convenient to insert the silicone tube into the uterus and will not be affected by the excessive bending position of the uterus. After the silicone tube is inserted into the uterus, the sleeve is withdrawn, and then water is injected into the expansion ball through the water injection head to expand the expansion ball, fix the silicone tube in the uterus, and finally inject contrast fluid into the silicone tube. The device is easy to use and is not affected by the excessive bending position of the uterus during hysterosalpingography. After the intubation is completed, the sleeve is withdrawn and the hysterosalpingography operation can continue.
[0008] Preferably, the angiography tube comprises a silicone tube, a discharge port for discharging the contrast fluid is provided at the front end of the silicone tube, and the sleeve is passed through the silicone tube.
[0009] Preferably, an expansion ball is mounted on the side end of the silicone tube relative to the discharge port, and a water injection head is mounted on the side of the silicone tube for injecting water into the expansion ball to expand the expansion ball.
[0010] Preferably, the sleeve is compatible with the silicone tube.
[0011] Preferably, an expansion ring is installed in the middle of the silicone tube, a limiting groove is opened on the inner wall of the sleeve, and an air supply pipe is installed on the side of the silicone tube for supplying air to the expansion ring, so that the expansion ring expands and embeds into the limiting groove. After the sleeve is assembled on the silicone tube, air is pumped into the air supply pipe to expand the expansion ring, thereby the expansion ring enters the limiting groove of the sleeve, thereby fixing the sleeve on the silicone tube. Through this structural design, the stability of the sleeve assembly can be guaranteed. When pulling out the sleeve, press the air release valve on the air supply pipe to deflate the expansion ring, thereby releasing the contact between the expansion ring and the limiting groove.
[0012] Preferably, the gas pipe is internally equipped with a gas relief valve.
[0013] Preferably, the length of the sleeve is 5.5-6CM.
[0014] Preferably, the outer edges of the sleeve are rounded.
[0015] In summary, the present invention has the following beneficial technical effects:
[0016] The device is convenient to use, and is not affected by excessive inclination of the uterus (such as forward inclination and flexion of the uterus and backward inclination and flexion of the uterus) in the process of tubal catheterization of the uterus, and after the catheterization is completed, the sleeve is withdrawn, and the liquid operation of the uterine tubal catheterization can be continued; if the soft uterine tubal catheterization is used, a dilatation rod (such as a No. 4 or No. 4.5 dilatation rod) is needed to repeatedly probe the position of the uterine cavity in order to successfully perform the catheterization, and the sleeve type device does not need to use the dilatation rod in the process of catheterization, and the catheterization can be completed at one time, which not only reduces the pain of the patient in the repeated dilatation of the cervix to probe the position of the uterine cavity, but also can be directly discarded after use, thereby avoiding repeated sterilization and packaging of surgical instruments.
[0017] The patient's pain is reduced, the soft uterine tubal catheterization needs a dilatation rod to repeatedly probe the position of the uterine cavity, the device can complete the catheterization at one time, and can be directly discarded after use, thereby avoiding repeated sterilization and packaging of surgical instruments.
