Description

Technical Field

[0001] This utility model relates to the field of hysteroscopy, and in particular to a hysteroscopy guide. Background Technology

[0002] A hysteroscopic guide is an auxiliary instrument specifically designed for hysteroscopic examinations and surgeries. It is mainly used to help doctors accurately insert the hysteroscope into the uterine cavity and perform related operations. The use of the guide can improve the safety and effectiveness of the operation.

[0003] The guiding tube is the main part of the guide device. The end of the guiding tube is designed with a pointed shape to facilitate insertion and positioning. The tip is usually flexible to reduce stimulation of the uterus and cervix. There are multiple small holes on the side of the tube body to drain fluid during insertion and help dilate the uterine cavity. However, when the fluid is injected, the degree of compression between the inner wall of the uterine cavity and the outer wall of the guiding tube will vary, resulting in different amounts of fluid being drained from different holes. It is also not convenient to drain fluid to a specific location in the uterine cavity according to the drainage needs, thus having certain defects. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model provides, for example Figure 1-4 The image shows a hysteroscopic guide.

[0040] Example 1

[0041] The device includes a first catheter 1, a second catheter 2, a first drain hole 3, a second drain hole 4, and a liquid inlet assembly 5. The first catheter 1 has an inner ring cavity on one side of its inner wall, and one end of the first catheter 1 is fitted with a silicone sleeve. The end of the silicone sleeve has a rounded bevel to reduce stimulation of the uterus and cervix. The second catheter 2 has an outer ring cavity on one side of its outer wall, and the second catheter 2 is rotatably connected to the inner ring cavity through the outer ring cavity. The first drain holes 3 are arranged in a spiral array outside the first catheter 1, and the second drain holes 4 are located at the end of the first catheter 1. Because multiple first drain holes 3 are arranged in a spiral array, liquid can be discharged from different first drain holes 3, allowing liquid to be discharged from different depths outside the first catheter 1. The liquid inlet assembly 5 is located between the first catheter 1 and the second catheter 2. The second catheter 2 rotates relative to the first catheter 1 to change the position where the liquid inlet assembly 5 supplies liquid to the first drain holes 3 and the second drain holes 4. That is, when the liquid inlet assembly 5 supplies liquid between the first catheter 1 and the second catheter 2, rotating the second catheter 2 allows liquid to be discharged from different positions of the first catheter 1.

[0042] Furthermore, the liquid inlet assembly 5 includes a fixing collar 51, a liquid inlet port 52, an annular chamber 541, and a flow limiting assembly 54. The fixing collar 51 is fixedly sleeved on the outside of the first conduit 1. A through hole 53 is provided on one side of the fixing collar 51. The liquid inlet port 52 is connected to the outside of the fixing collar 51. The inner cavity of the liquid inlet port 52 is interconnected with the inner cavity of the through hole 53. The annular chamber 541 is opened inside the inner annular cavity. The inner cavity of the annular chamber 541 is interconnected with the inner cavity of the through hole 53. That is, the liquid inlet port 52 is connected to an external syringe, so that liquid can be injected into the annular chamber 541. The flow limiting assembly 54 is disposed outside the second conduit 2. The flow limiting assembly 54 is used to regulate the flow direction of the liquid inside the annular chamber 541. That is, the flow limiting assembly 54 can restrict the flow direction of the liquid inside the annular chamber 541 when the liquid enters the annular chamber 541.

[0043] In particular, the flow-limiting assembly 54 includes a flow-limiting collar 542, an inlet port 543, and a partition 544. The flow-limiting collar 542 is fixedly sleeved on the outside of the second conduit 2 and rotatably sleeved on the inside of the annular chamber 541. The inlet port 543 is opened on one side of the flow-limiting collar 542, and the partition 544 is fixedly connected to one side of the flow-limiting collar 542. Two adjacent partitions 544 form a flow chamber with the first conduit 1 and the second conduit 2. The flow chamber communicates with the inner cavity of the inlet port 543. Figure 4 As shown, when the liquid inside the annular chamber 541 flows into the space between the two partitions 544 through the inlet hole 543, the flow chamber formed by the two partitions 544 is connected to the first drain hole 3 or the second drain hole 4 at different positions, so that the corresponding first drain hole 3 or the second drain hole 4 can discharge the liquid.

[0044] Furthermore, the flow-limiting assembly 54 also includes a sealing sleeve, a sealing strip, and a positioning collar 545. The sealing sleeve is fixedly fitted onto the side of the flow-limiting collar 542, and the sealing strip is fixedly connected to the side of the partition 544. The sealing sleeve and sealing strip can improve the sealing performance of the flow chamber. The positioning collar 545 is fixedly installed inside the annular chamber 541. The positioning collar 545 is located on one side of the flow-limiting collar 542 and is installed by an internal screw. The positioning collar 545 can limit the second conduit 2 through the flow-limiting collar 542, ensuring the stability of the rotational connection between the second conduit 2 and the first conduit 1. Moreover, there is a certain gap between the inner wall of the positioning collar 545 and the outer wall of the second conduit 2 to avoid the positioning collar 545 from blocking the annular chamber 541.

[0045] Example 2

[0046] Based on Embodiment 1, the liquid inlet assembly 5 further includes a limiting collar 55 and a sealing collar 56. The limiting collar 55 is fixedly connected to the outside of the second conduit 2, and the sealing collar 56 is fixedly connected to one side of the limiting collar 55. The sealing collar 56 is rotatably sleeved inside the annular chamber 541. The limiting collar 55 and the sealing collar 56 can ensure the sealing of one end of the annular chamber 541 and prevent the liquid inside the annular chamber 541 from flowing out from the end of the first conduit 1.

[0047] Furthermore, the liquid inlet assembly 5 also includes a handle 58 and an indicator 57. The handle 58 is fixedly connected between the second conduit 2 and the positioning collar 545. The indicator 57 is set on one side of the fixing collar 51. The indicator 57 corresponds to the first drain hole 3 and the second drain hole 4 on the first conduit 1. The indicator 57 corresponds to the handle 58. Thus, by using the handle 58 to drive the second conduit 2 to rotate, and observing the position of the handle 58 corresponding to the indicator 57 on one side of the fixing collar 51, the position of the drain on the first conduit 1 can be observed.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
