DETAILED DESCRIPTION
[0017] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar labels represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be explained as the limitation of the utility model.
[0018] Embodiment of the utility model: such as Figure 1 and Figure 2As shown, a probe sleeve for a dual-plane ultrasonic probe includes a sleeve 1, one end of which is a closed end and the other end is an open end. The closed end of the sleeve 1 has a spherical structure. An expansion bladder 2 is fixed on the wall of the sleeve 1. The expansion bladder 2 is composed of an annular bladder 3 and a linear bladder 4. One end of the linear bladder 4 is connected to the annular bladder 3, and the other end of the linear bladder 4 is connected to a feeding assembly. An outlet assembly is connected to the annular bladder 3.
[0019] The cannula 1 is a transparent plastic tube. The inner diameter of the cannula 1 is equal to the outer diameter of the small-diameter section of the housing of the dual-plane ultrasound probe. The convex array probe and the linear array probe of the dual-plane ultrasound probe are fixed on the small-diameter section of the housing. The large-diameter section of the housing of the dual-plane ultrasound probe is used as a handle, while the small-diameter section is used for insertion into the rectum through the anus.
[0020] Multiple rubber rings 12 are provided on the inner wall of the open end of the sleeve 1. The rubber rings 12 prevent the sleeve 1 from rotating after it is installed on the small diameter section of the housing of the dual-plane ultrasonic probe, and ensure that the annular bladder 3 always remains opposite to the convex array probe and the linear bladder 4 always remains opposite to the linear array probe.
[0021] In this embodiment, the length of the annular capsule 3 is equal to the length of the convex array probe, and the length of the linear capsule 4 is equal to the length of the linear array probe. The annular capsule 3 can completely cover the convex array probe, and the linear capsule 4 can completely cover the linear array probe.
[0022] The expansion sac 2 is made of rubber and expands after being filled with hydrogel. The ring-shaped sac 3 and the linear sac 4 are designed to accurately cover the convex array probe and the linear array probe, so that they will not compress the patient's rectum when they expand, thus reducing the patient's discomfort.
[0023] Specifically, the feeding assembly includes a feed pipe 5 and a one-way valve 6. The feed pipe 5 is fixed to the outer wall of the sleeve 1 and is made of rigid plastic. One end of the feed pipe 5 is fixedly connected to the linear capsule 4 and is internally connected. The other end of the feed pipe 5 is connected to the liquid outlet of the one-way valve 6 through a first connecting pipe 7. The liquid inlet of the one-way valve 6 is connected to the hydrogel ball 13 through a third connecting pipe 14.
[0024] The hydrogel sphere 13 contains hydrogel. When the hydrogel inside the hydrogel sphere 13 is squeezed into the annular sac 3 and the linear sac 4, the annular sac 3 and the linear sac 4 will expand uniformly without uneven size. This can expel the gas between the biplane ultrasound probe and the rectal wall, improving the imaging effect.
[0025] Furthermore, the discharge assembly includes a discharge pipe 8, a connector 9, and a sealing cap 10. The discharge pipe 8 is fixed on the outer wall of the sleeve 1. The discharge pipe 8 is a rigid plastic pipe. One end of the discharge pipe 8 is fixedly connected to the annular bladder 3 and is internally connected. The other end of the discharge pipe 8 is fixedly connected to the connector 9 through a second connecting pipe 11. The sealing cap 10 is threadedly connected to the connector 9.
[0026] In this embodiment, the use of rigid plastic tubes for the discharge tube 8 and the feed tube 5 can increase the wall strength of the sleeve 1, making it easier to install the sleeve 1 onto the small-diameter section of the dual-plane ultrasonic probe housing.
[0027] Both the first connecting tube 7 and the second connecting tube 11 are soft plastic tubes. Therefore, the first connecting tube 7 and the second connecting tube 11 are located outside the sleeve 1. Designing them as flexible tubes can avoid interference with the large-diameter section of the housing of the dual-plane ultrasonic probe.
[0028] The working principle of this invention is as follows: In use, first, the cannula 1 is fitted onto the small-diameter section of the dual-plane ultrasound probe housing. Then, check if the angle is suitable. If not, make fine adjustments so that the annular capsule 3 covers the convex array probe and the linear capsule 4 covers the linear array probe. After adjusting the angle, due to the rubber ring 12, the cannula 1 will not rotate on the dual-plane ultrasound probe during use. The small-diameter section of the dual-plane ultrasound probe with the cannula 1 fitted is then inserted into the rectum through the patient's anus.
[0029] Then, the hydrogel ball 13 is squeezed, and the hydrogel inside the hydrogel ball 13 enters the linear sac 4 and the annular sac 3 through the third connecting tube 14, the one-way valve 6, the first connecting tube 7, and the feed tube 5, causing the linear sac 4 and the annular sac 3 to expand uniformly. The expanded linear sac 4 and the annular sac 3 can expel the gas between the convex array probe and the linear array probe and the rectal wall, resulting in better imaging and more accurate examination results. Moreover, because the expanded shape of this invention is uniform, it will not cause excessive compression of the rectum, reducing patient discomfort.
[0030] After the examination is completed, unscrew the sealing cap 10. The hydrogel will flow out from the connector 9 through the discharge tube 8 and the second connecting tube 11. However, it will not flow out completely. It is necessary to use a syringe from the prior art to connect to the connector 9 and then use the syringe to extract the remaining hydrogel. At this time, the annular sac 3 and the linear sac 4 become smaller, and the biplane ultrasound probe along with the cannula 1 can be removed without causing damage to the patient's anus.
[0031] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
