Description

Technical Field

[0001] This utility model relates to the field of fallopian tube examination technology, and in particular to a fallopian tube hysterosalpingography (HSG) tube. Background Technology

[0002] In clinical medicine, determining the patency of the fallopian tubes is a crucial examination for assessing female fertility. Currently, the commonly used method is to inject a contrast agent (such as methylene blue) into the uterine cavity and observe the flow of the contrast agent to determine the patency of the fallopian tubes. Traditional methods typically use a modified urinary catheter as the injection tool; the catheter is shortened and inserted into the uterine cavity, and then the contrast agent is injected through the catheter. However, in this method, due to differences in cervical length among different patients, the length of the modified urinary catheter is difficult to precisely match, leading to inaccurate insertion depth. Furthermore, traditional urinary catheters lack positioning aids, forcing doctors to rely on experience to determine whether the catheter has reached the uterine cavity, which can easily result in positional errors.

[0003] To address these issues, in practice, medical staff will first place the contrast agent in the uterine cavity, allowing it to flow backwards and into the uterine cavity. The entire imaging process requires a large amount of contrast agent and takes a considerable amount of time. Furthermore, because some patients have cervical insufficiency or prolapse, the contrast agent is prone to leakage and cannot effectively enter the fallopian tubes, making it impossible to accurately determine whether the fallopian tubes are open or not. Utility Model Content

[0004] The present invention aims to provide a fallopian tube contrast examination tube to solve the technical problems of large contrast agent consumption, long time consumption, and easy leakage of contrast agent in special patients during the traditional use of urinary catheter modified contrast agent delivery tube.

[0005] This utility model provides a fallopian tube imaging examination tube, specifically comprising:

[0006] The guide tube has an internal delivery tube, and one end of the guide tube has a bifurcation area; the delivery tube is a three-way pipe, and its two ends are respectively connected to the two ends of the bifurcation area; the guide tube has a closed state and an extended state. When the guide tube is placed outside the uterus, it is in the closed state, and the bifurcation area is closed and collinear with the central axis of the guide tube; after the guide tube is inserted into the uterus, it is in the extended state, and the bifurcation area is extended into a Y shape.

[0007] Preferably, the end of the guide tube away from the bifurcation area is connected to a connector, the connector having an infusion interface, and the infusion interface of the connector communicating with the delivery tube.

[0008] Preferably, the guide tube has mounting holes inside, and there are at least two mounting holes, which are located at both ends of the bifurcation area; the connecting seat is provided with elastic elements corresponding to the mounting holes, and the elastic elements are respectively inserted into the mounting holes of the guide tube.

[0009] Preferably, the elastic element is made of shape memory alloy, and the elastic element has a naturally curved front end when in the initial environment, and can be straightened when in the excitation environment.

[0010] Preferably, the elastic element is a metal rod with a naturally bent front end; a control rod is slidably connected inside the connecting seat, and the control rod is inserted inside the guide tube; a limiting element is provided at one end of the control rod near the bifurcation area, the limiting element is a U-shaped structure, and when the bifurcation area is in a contracted state, the limiting element is inserted between the two ends of the bifurcation area.

[0011] Preferably, the end of the control lever away from the limiting member is provided with a handle.

[0012] Preferably, an air bladder is provided on the outside of the guide tube, and an air supply pipe is provided on the air bladder; the air supply pipe of the air bladder is connected to the outside.

[0013] Preferably, the surface of the guide tube is provided with graduations, and the airbag can slide on the outside of the guide tube.

[0014] Beneficial effects

[0015] In this invention, the bendable bifurcated section at the front end of the guide tube can enter the uterus in a closed state and gradually unfold inside the uterus until both ends of the bifurcated section are aligned with the connection between the uterus and the fallopian tubes. This allows the injected contrast agent to enter the patient's fallopian tubes more accurately and directly, effectively solving the problems of high contrast agent consumption and long operation time caused by filling the patient's uterus with contrast agent in current practical operations. At the same time, since the contrast agent is injected directly into the fallopian tubes and the amount of contrast agent used is small, it can also avoid the problem of contrast agent leakage caused by cervical relaxation, making the test results more accurate.

[0032] Example: Please refer to Figures 1 to 8 :

[0033] like Figure 1 and Figure 8 As shown, this utility model proposes a fallopian tube imaging examination tube, comprising:

[0034] The guide tube 1 has an internal delivery tube 102, and one end of the guide tube 1 has a bifurcation area 101; the delivery tube 102 is a three-way tube, and both ends of the delivery tube 102 are connected to the two ends of the bifurcation area 101 of the delivery tube 102 respectively; the guide tube 1 has a closed state and an extended state. When the guide tube 1 is placed outside the uterus, it is in the closed state, and the bifurcation area 101 is closed and collinear with the central axis of the guide tube 1; after the guide tube 1 is inserted into the uterus, it is in the extended state, and the bifurcation area 101 extends into a Y-shape; the bifurcation area 101 of the guide tube 1 has a certain bending angle, specifically bending along the central axis of the guide tube 1 to both sides, such as... Figure 8 As shown, when inside the patient's uterus, it unfolds in a Y-shape. In a specific embodiment, this bend can be achieved by relying on the elasticity of the material and the application of shape memory alloy. The bifurcation region 101 of the guide tube 1 enters the patient's uterus in a closed state, and its two ends gradually unfold as they contact the inner wall of the uterus until the two ends of the bifurcation region 101 respectively contact the connection between the fundus of the uterus and the fallopian tube. Since the fallopian tube is located at the bottom of the uterus, the location of the fallopian tube can be determined by the contact between the bifurcation region 101 of this device and the inner wall / fundus of the uterus. The two ends of the bifurcation region 101 are round or semi-circular ball heads, and the delivery tube 102 is connected to the outside through the ball heads. After the bifurcation region 101 reaches the above-mentioned area, the contrast agent can be accurately delivered into the fallopian tube, thereby reducing the waste of contrast agent and preventing the contrast agent from leaking out of the uterine cavity.

[0035] Among them, such as Figure 2 and Figure 4 As shown, the end of the guide tube 1 away from the bifurcation area 101 is connected to a connector 104. The connector 104 has an infusion interface, and the infusion interface of the connector 104 is connected to the delivery tube 102. The connector 104 and the guide tube 1 are connected in a detachable manner. The guide tube 1 is for single use. At the same time, the connector 104 and its connected control rod 2, elastic element 105, etc. are all reusable devices, which can effectively save medical costs.

[0036] Among them, such as Figure 3 , Figure 5 and Figure 7 As shown, the guide tube 1 has an installation hole 103 inside, and there are at least two installation holes 103, which are located at both ends of the bifurcation area 101 respectively; the connecting seat 104 is provided with an elastic element 105 corresponding to the installation hole 103, and the elastic element 105 is inserted into the installation hole 103 of the guide tube 1 respectively.

[0037] In one embodiment, the elastic element 105 is made of shape memory alloy. When the elastic element 105 is in the initial environment, it has a naturally curved front end and can be straightened when it is in the stimulating environment. The initial environment can represent a temperature range similar to the temperature environment inside the uterus, while the stimulating environment is a high / low temperature range with a large difference from the temperature environment inside the uterus. This allows the elastic element 105 to form a contracted state in the bifurcation region 101 when it is in the stimulating environment, and it is placed inside the patient's uterus. After entering the uterus, it is in the initial environment and returns to the unfolded state.

[0038] In another embodiment, such as Figure 2 , Figure 4 and Figure 6 As shown, the elastic element 105 is a metal rod with a naturally bent front section; a control rod 2 is slidably connected inside the connecting seat 104, and the control rod 2 is inserted inside the guide tube 1; a limiting element 201 is provided at one end of the control rod 2 near the bifurcation area 101. The limiting element 201 has a U-shaped structure, and when the bifurcation area 101 is in the retracted state, the limiting element 201 is inserted between the two ends of the bifurcation area 101; the length of the limiting element 201 is equal to the length of the elastic element 105 inserted into the bifurcation area 101. Within the length of 1, when the elastic member 105 is straightened, the bifurcation area 101 is in a contracted state, and the limiting member 201 limits the elastic member 105, so that the elastic member 105 and the bifurcation area 101 remain in a taut state. As the control rod 2 controls the limiting member 201 to leave the bifurcation area 101, the constraint of the limiting member 201 on the elastic member 105 is gradually released. Then, under the action of elastic potential energy, the elastic member 105 gradually bends, and drives the bifurcation area 101 to gradually bend.

[0039] Among them, such as Figure 2 As shown, the end of the control lever 2 away from the limiting member 201 is provided with a handle.

[0040] Among them, such as Figure 1 and Figure 5 As shown, an airbag 3 is provided on the outside of the guide tube 1, and an air supply tube 301 is provided on the airbag 3; the air supply tube 301 of the airbag 3 is connected to the outside; the airbag 3 is used to seal the cervical opening to further prevent the contrast agent from leaking out.

[0041] In one embodiment, the surface of the guide tube 1 is provided with a scale, and the balloon 3 can slide outside the guide tube 1; the length of the guide tube 1 entering the uterus can be accurately controlled by the scale on the surface of the guide tube 1, and the slidable balloon 3 can adjust the position of the balloon 3 according to the position of the cervix when it is necessary to block the cervix, according to the specific situation of the patient.
