[0037] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The embodiment of the present application solves the problem that the curette cannot be turned when used in the uterus by providing a visualized intrauterine curette. Combined with the visualized design, the curette can detect lesions when used in the uterine cavity and accurately scrape the lesions, making intrauterine surgery more efficient and safe.

[0039] Therefore, the inventor proposes an inventive concept:

[0040] Embodiment 1:

[0041] See also Figure 1 The embodiment of the present application provides a visualized uterine cavity curette, comprising a curette head 1, a connecting rod 2 fixedly connected to the curette head 1 at one end, and a handle 3 fixedly connected to the other end of the connecting rod 2.

[0042] See also Figure 1-3 A scraper head 1 is fixed at one end of the visualized uterine cavity scraper connecting rod 2. The scraper head 1 is a teardrop-shaped strip structure, and the teardrop-shaped tip is fixed on the connecting rod 2. At least one side of the edge of the strip structure is a sharp blade for cutting and scraping the patient's diseased tissue.

[0043] In this case, the scraper head 1 needs to be pulled toward the handle to cut and scrape. In order to further increase the use directions of the scraper head, another second cutting edge 12 is arranged opposite to the first cutting edge 11 of the scraper head 1. The first cutting edge 11 and the second cutting edge 12 are elliptical in the scraper head 1.

[0044] See also Figure 1-3 The connecting rod 2 is divided into three sections, which are the first section 21, the second section 22 and the third section 23 from the scraper head 1 to the handle 3. The first section 21 is fixedly connected to the closed end 24 of the scraper head 1; the second section 22 is a metal bellows at one end, and both ends of the second section 22 are fixedly connected to the first section 21 and the third section 23 for steering, so that any angle can be formed between the first section 21 and the third section 23 when in use; the two ends of the third section 23 are fixedly connected to the second section 22 and the handle 3 respectively.

[0045] It should be emphasized that, in specific implementation, the method of making the second section 22 swingable is not limited to the structure of a metal bellows, and its structure can also be other structures that can be bent at any angle. For example, the second section 22 can also be a hose made of flexible materials such as plastic and silicone.

[0046] See also Figure 3In the embodiment of the present application, a cavity is passed through the interior of the three-section rod, and an upper pull wire 25 and / or a lower pull wire 26 are passed through the cavity. One end of the upper pull wire 25 and / or the lower pull wire 26 is fixed to the inner side of the end 24. The fixing point of the upper pull wire 25 on the inner side of the end 24 is located on one side of the projection of the scraper head 1 on the end 24, and / or the fixing point of the lower pull wire 26 on the inner side of the end 24 is located on the other side of the projection of the scraper head 1 on the end 24. By tensioning the upper pull wire 25, the first section 21 can be swung to one side, further driving the scraper head 1 to move to one side; by tensioning the lower pull wire 26, the first section 21 can be swung to the other side, further driving the scraper head 1 to move to the other side; because the second section 22 itself has a certain toughness and deflection, the upper pull wire 25 and / or the lower pull wire 26 are relaxed, and the connecting rod 2 will slowly rebound to a normal state.

[0047] See also Figure 4 and Figure 5 In order to facilitate the operation of the operator, in the embodiment of the present application, a rotating assembly 4 is provided on the handle 3, and the other ends of the upper pull wire 25 and the lower pull wire 26 are connected to the rotating assembly 4. The rotating assembly 4 includes a chain 41 arranged inside the handle 3, a sprocket 42 adapted to the chain 41, and a handwheel 43 arranged outside the handle 3. The two ends of the chain 41 are respectively connected to the other ends of the upper pull wire 25 and the lower pull wire 26; the handwheel 43 is fixedly connected to the sprocket 42 through a shaft 44 that passes through the outer wall of the handle 3. Since the upper pull wire 25 and the lower pull wire 26 are not on the same plane as the rotating mechanism, a plurality of steering members 31 are provided inside the handle 3 to guide the upper and lower pull wires, so as to assist the upper pull wire 25 and the lower pull wire 26 to be on the same plane as the sprocket 42 when turning.

[0048] When in use, the hand wheel 43 is rotated clockwise, and the sprocket 42 is driven to rotate clockwise through the shaft 44. After the sprocket 42 rotates clockwise, the chain 41 on the upper side of the sprocket 42 is further pulled, and the chain 41 drives the connected upper pull line 25 to be tightened, and further drives the scraper head 1 to swing upward; then the hand wheel 43 is rotated counterclockwise, at this time, the upper pull line 25 is relaxed and the lower pull line 26 is tightened, and the scraper head 1 returns to the normal state and can continue to swing downward.

[0049] Attached Figure 4 and Figure 5 The two ends of the chain 41 shown in the figure are connected to the other end of the upper pull wire 25 and the lower pull wire 26, which is only one implementation method of the present application to achieve tensioning of the upper and lower pull wires. Other methods of achieving the purpose of tensioning the upper and lower pull wires are also within the protection scope of the present application. For example, in another embodiment, the other end of the upper pull wire 25 and / or the lower pull wire 26 is directly fixed to the shaft 44 or the component driven by it, and the length of the upper pull wire 25 or the lower pull wire 26 is reduced by rotating and winding the shaft.

[0050] See also Figure 2In order to enable medical staff to find the lesion more accurately without damaging the normal endometrium, in the embodiment of the present application, a visualization component is also provided in the visualization uterine cavity scraper, and the above-mentioned visualization component includes a camera and LED light source 27, and a signal and power line group 28. The camera and LED light source 27 are fixedly mounted on the end 24 and are arranged next to the scraper head 1; one end of the signal and power line group 28 is electrically connected to the camera and LED light source 27, and the other end penetrates the end 24 and extends along the inside of the connecting rod 2 to the handle 3, and extends from the end of the handle 3 to be connected to the video receiving and display device adapted to the visualization component. The video receiving and display device adapted to the visualization component is not specifically limited, and it can receive the data of the camera and display it.

[0051] Further, see Figure 2-Figure 6 Considering that the bleeding during the scraping of the patient's lesion affects the visualization effect of the scraper, in the embodiment of the present application, a water channel 29 is also provided in the scraper. One end of the water channel 29 made of a hose is connected to the end 24 and opened to the outside, and the other end extends from the back of the handle 3 and is connected to the A port 51 of the L-type three-way valve 5. The B port 52 of the L-type three-way valve 5 is connected to the water pressure device, and the C port 53 is connected to the suction device. The valve flap 54 in the L-type three-way valve 5 is L-shaped. When in use, physiological saline is pumped into the scraper through the water pressure device, and the physiological saline is sprayed from the opening near the scraper head 1 to clean the inner wall of the uterus. At this time, the A port 51 and the B port 52 of the L-type three-way valve 5 are connected, and the physiological saline will not enter the suction device; after cleaning, the L-type three-way valve 5 is switched, the internal valve flap 54 rotates, and the flow channel is switched from the state of connecting the A port 51 and the B port 52 to the state of connecting the A port 51 and the C port 53. At this time, the suction device is turned on, and the suction device will only absorb the flushing water in the uterus from the front end of the scraper.

[0052] Embodiment 2:

[0053] In the above-mentioned embodiment 1, a cavity is set inside the connecting rod 2, and the upper pull wire 25 and / or the lower pull wire 26, and / or the signal and power line group 28 are directly set in the cavity, and / or a hose is used as a water channel 29. Different from this in the embodiment of the present application, multiple cavities are set inside the first section 21 and the third section 23 of the connecting rod 2, and the upper pull wire 25 and the lower pull wire 26 are respectively set in the first cavity and the second cavity, and / or the signal and power line group 28 is set in the third cavity, and / or the fourth cavity is used as a water channel 29. Since the second section 22 needs to maintain the function of the swing angle, and the second section 22 is a cavity, a hose is set in the second section 22 to connect the fourth cavity between the first section 21 and the third section 23.

[0054] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. The utility model provides a flexible section on the connecting rod and sets a pull wire through the connecting rod, so that the connecting rod can form any angle, and further enables the scraper head to swing, so that it can accurately reach the position that the operator wants to reach in the patient's body and accurately scrape the lesion.

[0056] 2. The utility model combines a visual design so that the curette can quickly find the lesion when used in the uterine cavity and accurately scrape the lesion, making uterine cavity surgery more efficient and safe.

[0057] 3. The utility model provides a water channel so that the scraper has the function of suction and / or flushing, so that the scraper not only has a good effect of cleaning the uterus, but also has the function of absorbing the flushing water in the uterus.
