[0002] Hysteroscopic surgery is usually performed in the lithotomy position, which means that the operating table is adjusted to a position with the head lower than the feet by about 15 degrees, the legs are bent at the hips, and the knees are placed on the tripods. During the operation, a large amount of uterine distention fluid is required for uterine distention and flushing, so sterile cloth needs to be laid around the surgical site. As the operation progresses, the sterile cloth will be soaked or contaminated, and it needs to be replaced repeatedly. Especially when collecting samples, a large amount of liquid will flow out of the body as the hysteroscope lens is withdrawn. First, the sterile cloth will be consumed, and second, the sample may flow into the dirt bucket or stick to the sterile cloth along with the outflow of uterine distention fluid, which is very inconvenient for collecting small samples. In addition, the cost of sterile cloth is also high, which will increase medical costs and the economic burden on patients. Utility Model Content

DETAILED DESCRIPTION
[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.
[0032] Embodiment 1:
[0033] This embodiment provides a preferred gynecological hysteroscopic surgery auxiliary instrument, such as Figure 1As shown, the device as a whole is composed of a docking portion 100, a collection net fixing portion 300 and a collection bucket 200 connected in sequence from top to bottom, and the top-view cross-sectional shape of the device is an isosceles rounded triangle. Moreover, the sizes of the docking portion 100 and the collection bucket 200 are different, and the size of the collection bucket 200 is smaller than the size of the docking portion 100. Specifically, the top-view cross-sectional shapes of the docking portion 100 and the collection bucket 200 are both isosceles rounded triangles, and the docking portion 100 and the collection bucket 200 are similar triangles, and the docking portion 100 and the collection bucket 200 are connected by a curved surface to form a curved surface that converges inwardly (inside the device). In this embodiment, the distance between two similar isosceles triangles is 1-3cm. The docking portion 100 is open at the top, and the collection bucket 200 is sealed at the bottom, thereby forming a cavity with an upper opening, and the cavity is used to collect effluent.
[0034] The use of a rounded triangular column structure is convenient; when placed diagonally along the bottom edge, the bottom edge provides support for the instrument, thereby ensuring that the instrument is stably placed on the operating table / bed.
[0035] The front cross-sectional shape of the docking portion 100 is a rectangular structure, wherein the upper side of the rectangle is a curve, and the curve has a downward concave portion 110 and an upward convex portion 120. Specifically, Figure 1 As shown, the left part of the rectangle curves downward, and the right side of the rectangle near the center line is a recessed portion 100, and then a raised portion 120 is formed upward along the recessed portion. The raised portion 120 is close to the right side of the rectangle, and then extends downward along the right side of the raised portion 120 until it reaches the right side of the rectangle. The shape of the docking portion 100 fits the structure of the vagina (specifically, the height and position of the recessed portion 110 and the raised portion 120 can be further optimized based on the data of the vagina). For greater comfort, the docking portion 100 is made of comfortable silicone material. At the same time, the collection bucket 200 is preferably made of hard material to provide sufficient support.
[0036] In the structure of this embodiment, the raised portion 120 near the right edge is necessary. Figure 5 As shown, due to the presence of the raised portion 120, a slope inclined upward (at the angle shown in the figure, this time it is the upper left) is constructed on the right edge, and the slope provides support for the placement of hysteroscopic surgical instruments. As one of the optimizations, the right edge position is raised upward by 1-3 cm to form a splash guard 130, and the middle position of the splash guard 130 (i.e., the position of the top angle) is recessed downward to form a support portion 140. At this time, the instrument is placed in the support portion 140, and the instrument 140 will be stored and fixed in the support portion 140 and will not slide at will. The splash guard 130 is to prevent the liquid from splashing onto the outside of the docking portion 100 when a large amount of liquid is sprayed along the direction of lens extraction during the lens extraction process.
[0037] The sample collection net 400 is detachably placed on the collection net fixing part 300 for use. Specifically, Figure 2 , Figure 3 and Figure 4 As shown, the sample collection net 400 is composed of a rod body 430 and a net body 440 connected to the rod body 430. The top view cross-sectional shape of the rod body 430 is also a rounded triangle, which is similar to the docking part 100 and the collection barrel 200. However, the size of the triangle where the rod body 430 is located is between the docking part 100 and the collection barrel 200. After the rod body 430 is placed above the docking part 100, the rod body 430 is fixed on the collection net fixing part 300. The net body 400 is a liquid-impermeable or liquid-permeable mesh structure, but the mesh holes of the mesh structure are small, only allowing liquid to pass through, and the sample as a block shape cannot pass through the net body 440.
[0038] As an optimized structure of the sample collection net 400, a filter net 410 is provided at the bottom of the net body 440. The filter net 410 is a porous structure, and its pore size also only allows liquid to pass through. Block objects such as samples cannot pass through the holes, but the hole size at the filter net is larger, and the advantage is that the liquid flows faster.
[0039] At least one handle 420 is fixed above the rod body 430 of the sample collection net 400. The handle 420 is used to facilitate the placement and removal of the sample collection net 400. Figure 3 As shown, in this embodiment, the handle 420 is disposed at the center of the left side.
[0040] The instrument in this embodiment is preferably made of a transparent material, which can facilitate surgical operations and allow observation of sample collection and / or liquid collection at any time.
[0041] Embodiment 2:
[0042] On the basis of Example 1, this embodiment provides a method for dealing with liquid re-outflow. The purpose of re-outflow is to collect the liquid into a waste liquid barrel for unified treatment. In Example 1, after completing the sample collection, the sample collection net 400 can be taken out to take out the sample, and then the liquid in the device can be poured out along a corner above the docking part 100; as an optional method, a liquid absorption gel can be pre-placed inside the collection barrel 200. When the liquid flows in, the gel reaction solidifies the liquid into a solid, and there is no need to worry about the problem of liquid re-outflow.
[0043] In this embodiment, the supporting and guiding integrated part 500 selected for the liquid re-flowing method is as follows: Figure 6As shown, the outer side of the supporting and guiding integrated part 500 is an outer shell 510, and the outer shell 510 can be bent and fixed to form a certain angle after bending, so as to support the collecting barrel 200. There is a connected guiding pipe 520 inside the outer shell, and the guiding pipe 520 is connected to the inside of the collecting barrel 200. The liquid inside the collecting barrel 200 can flow out through the guiding pipe 520; the outer side of the free end of the supporting and guiding integrated part 500 is sealed by a cover body (not shown in the figure) and opened when needed.
[0044] like Figure 7 As shown, in addition to being able to be bent and fixed, in order to enhance its fixing strength and storage, the support and guide integrated part 500 is recessed inward on the lower surface of the storage barrel 200 to form a storage groove, and the right end of the storage groove is close to the outer shell 510, and the outer shell 510 can also be bent at this point, and can be stored in the storage groove after bending. There are several support blocks 540 in the storage groove, and the support rod 530 can be movably connected to the left side of the outer shell 510 (the side close to the storage groove), and the support rod 530 can abut against the support block 540 to achieve enhanced fixation of the outer shell 510.
[0045] Embodiment 3:
[0046] In Example 1, the rounded triangular column structure is also advantageous for folding and storage. This embodiment provides an optimized folding solution, which is more advantageous for transportation and storage.
[0047] Specifically, Figure 8 and Fig. 9 As shown, a support ring 600 is added to the device, and the shape and size of the support ring 600 are comparable to those of the rod body 430. Preferably, the size of the support ring 600 is slightly smaller than that of the rod body 430, but still larger than that of the collection barrel 200. During assembly, the support ring 600 is spread open and supported at the collection net fixing portion 300, and then the sample collection net 400 is fixed above the support ring 600.
[0048] Preferably, the support ring 600, the docking portion 100, the collection bucket 200, the collection net fixing portion 300, and the sample collection net 400 (rod body 430) can be folded along the folding position 700, and the folding position 700 is located at the center of the bottom edge. There are many folding methods. For example, the support ring 600 can connect the ring bodies 600 on both sides through movable anchors; for another example, the left and right sides of the bottom edge and the corner connection parts of the storage bucket 200 can be set to a plug-in connection structure through a plug-in structure connection. In the foldable connection method, it is more difficult to completely seal, and the collection of liquid can be achieved by fixing the collection bag in the storage bucket. At this time, the guide tube 520 in the support guide integrated part 500 is connected to the collection bag.
[0049] The parts of the present invention that are not described in detail are prior art. Although the present invention is specifically demonstrated and introduced in conjunction with the preferred implementation scheme, there are many methods and ways to implement the technical solution. The above is only a preferred implementation scheme of the present invention. However, technical personnel in the field should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined in the attached claims, which are all within the scope of protection of the present invention.
