Therefore, this utility model is not limited to the specific embodiments disclosed below. Embodiments of this utility model will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Please see Figure 1 , Figure 3 and Figure 8 The wireless hysteroscope with screen 100 of this utility model includes a handle 10, a circuit board 20, an insertion part 30, a wireless display screen 40, and a wireless module 50. The wireless module 50 is electrically connected to the circuit board 20 mounted on the handle 10, and the wireless module 50 is also wirelessly connected to the wireless display screen 40 to meet the need for the circuit board 20 to communicate wirelessly with the wireless display screen 40 through the wireless module 50.

[0037] Meanwhile, the wireless display screen 40 is detachably mounted on the handle 10, which facilitates the operator's installation and removal of the wireless display screen 40, and also makes it easier for the operator to view the wireless display screen 40 after it is assembled.

[0038] The insertion part 30 is elongated to facilitate insertion and removal within the uterine cavity. The tail end 31 of the insertion part 30 is fitted to the handle 10, which provides support. The head end 32 of the insertion part 30 is located away from the handle 10 to ensure sufficient length for insertion into the uterine cavity. Specifically, in conjunction with... Figures 1 to 7 As an example, the handle 10 is provided with a slot 11 extending along the length direction of the insertion portion 30 (see the direction indicated by arrow A and the opposite direction). The wireless display screen 40 is provided with a protrusion 41 that mates with the slot 11. Therefore, by engaging or disengaging the protrusion 41 along the length direction of the insertion portion 30 into or out of the slot 11, the assembly or disassembly of the wireless display screen 40 on the handle 10 is correspondingly realized. For example, in Figure 2 When assembling the wireless display screen 40 onto the handle 10, first align the latching protrusion 41 with the latching slot 11 along the length of the insertion part 30; after alignment, move the latching protrusion 41 relative to the latching slot 11 in the direction indicated by arrow A until the latching protrusion 41 and the latching slot 11 are fully engaged. The engagement state is shown in [the diagram]. Figure 5 As shown; when it is necessary to Figure 1 When the wireless display screen 40 is removed from the handle 10 in the state shown, simply disengage the latch 41 from the slot 11 in the opposite direction of arrow A. Therefore, the cooperation between the latch 41 and the slot 11 effectively improves the ease of installation and removal of the wireless display screen 40. It should be noted that although... Figure 1 , Figure 2 , Figure 3 and Figure 6 The diagram shows that the protrusion 41 is provided by the wireless display screen 40 and the slot 11 is provided by the handle 10. Obviously, their positions can be interchanged according to actual needs, so that the slot 11 is provided by the wireless display screen 40 and the protrusion 41 is provided by the handle 10. Therefore, it is not considered... Figure 1 , Figure 2 , Figure 3 and Figure 6 The above is a limited description. More specifically, as follows:

[0039] Combination Figure 4 , Figure 6 and Figure 7 As an example, there are two slots 11 arranged spaced apart from each other around the handle 10. Alternatively, one slot 11 may be located on the left side of the handle 10 and the other on the right side, so that the slots 11 are arranged opposite each other on the handle 10, thereby increasing the number of mounting points between the wireless display screen 40 and the handle 10, and thus improving the support strength of the handle 10 for the wireless display screen 40. Obviously, depending on actual needs, the number of slots 11 can also be three, four or five, so the number of slots 11 is not limited to... Figure 4 , Figure 6 and Figure 7As shown, since the protrusion 41 is used to engage with the slot 11, it is preferable that the number of protrusions 41 and slots 11 are the same to meet the requirement that one protrusion 41 engages with one corresponding slot 11. The wireless display screen 40 is provided with an arched structure 42 arranged around the handle 10. The protrusion 41 is located on the inner side 421 of the arched structure 42 facing the handle 10. Therefore, the arched structure 42 can increase the surrounding angle of the wireless display screen 40 on the handle 10, thereby improving the stability and reliability of the wireless display screen 40 mounted on the handle 10. Specifically, in Figures 1 to 4 and Figures 6 to 7 As an example, the lower side 43 of the wireless display screen 40 has a downwardly protruding connecting structure 44 in the middle. The connecting structure 44 is connected to the middle of the outer side 422 of the arched structure 42 to ensure that the arched structure 42 provides reliable support for the middle of the wireless display screen 40 with the help of the connecting structure 44, thereby improving the support reliability of the wireless display screen 40. In addition, the head end 111 of the slot 11 is a closed end and the tail end 112 of the slot 11 is an open end to control the direction of the protrusion 41 entering and exiting, that is, it can only enter and exit the slot 11 from the tail end 112. The slot of the slot 11 includes a first slot 113 and a second slot 114. The first slot 113 is arranged facing the wireless display screen 40 where the protrusion 41 is located, and the second slot 114 is located on the tail end face 1121 of the slot 11. This allows the protrusion 41 of the wireless display screen 40 to slide into or out of the slot 11 only from the second slot 114.

[0040] Combination Figures 1 to 3 As an example, the wireless module 50 and the circuit board 20 are each located inside the handle 10, which hides and protects them, thus making the appearance of the wireless hysteroscope with screen 100 of this invention simpler. Furthermore, the circuit board 20 is located between the wireless module 50 and the tail end 31 of the insertion part 30, making reasonable use of the space within the handle 10. Specifically, in Figure 3 In this example, the wireless module 50 is mounted inside the handle 10, which provides support. Obviously, depending on actual needs, the wireless module 50 can also be mounted on the circuit board 20. Figure 3 The above is the limit.

[0041] Combination Figure 8 and Figure 9 As an example, the handle 10 is provided with an instrument guide channel 13 for guiding an external instrument from the end face 12 of the handle 10 into the end 32 of the insertion part 30. The instrument guide channel 13 is provided with a seal 60 for sealing and isolating the instrument guide channel 13.

[0042] Combined Figure 10 and Figure 11As an example, the seal 60 includes a sealing body 61 for sealingly engaging with the instrument guide channel 13, a tapered extension 62 extending from the sealing body 61 toward the tail end 31 of the insertion portion 30, and a blind hole 63 simultaneously formed in both the extension 62 and the sealing body 61. The opening 631 of the blind hole 63 is located on the end face 611 of the sealing body 61 opposite to the extension 62, making the seal 60 designed in a duckbill shape. This allows the insertion and removal position of the external instrument on the seal 60 to be arranged at the tapered extension 62. Furthermore, because the extension 62 is tapered, it better seals the instrument passing through the extension 62 from the side, thus improving the sealing effect. On the other hand, the tapered extension 62 acts as a guide during instrument insertion, improving the smoothness of insertion and removal. For the specific structure of the seal 60, please see the description below:

[0043] Combination Figures 10 to 13 As an example, the extension 62 is positioned to enclose the blind hole 63 with the center line of the blind hole 63 (see...). Figure 13 Two inner inclined surfaces 621 arranged opposite each other with the center line of the extension body 62 as the center; this design, on the one hand, makes the sealing effect of the extension body 62 on the instruments passing through it better, and on the other hand, provides better guidance during the passage of the instruments, thereby effectively improving the smoothness of instrument insertion and removal; alternatively, in Figure 13 In the example shown, the two inner inclined surfaces 621 are arranged symmetrically with the center line of the blind hole 63 as the center; furthermore, the two inner inclined surfaces 621 intersect each other and the intersection line 622 is perpendicular to the center line of the blind hole 63, as shown in the figure. Figure 13 As shown, this design further improves the sealing effect and the smoothness of insertion and removal.

[0044] And combined Figures 10 to 13 As an example, the outer surface of the extension 62 has two external bevels 623 arranged opposite each other with the center line of the blind hole 63 as the center. The two external bevels 623 are arranged in a figure-eight shape. This design allows for thinning of the extension 62, making it easier for the instrument to pass through the extension 62. Specifically, in Figure 13 In the middle, as an example, on the same side (see Figure 13 The outer bevel 623 and inner bevel 621 in the left or right side of the extension 62 are parallel to each other to ensure the thickness consistency of the extension 62 between the outer bevel 623 and the inner bevel 621. Additionally, in Figure 13 In this example, the outer end face 624 of the extension 62 is a plane perpendicular to the center line of the blind hole 63. This design ensures that external instruments are inserted and removed from the extension 62 in a direction perpendicular to the outer end face 624, thereby improving the smoothness of instrument insertion and removal from the extension 62. Furthermore, in Figure 13In the example, the centerline of the sealing body 61 coincides with the centerline of the blind hole 63 (see). Figure 13 (The center line in the middle) to facilitate the manufacturing and processing of the seal 60.

[0045] Compared with the prior art, by using the wireless module 50 electrically connected to the circuit board 20 and the wireless display screen 40 wirelessly communicating with the wireless module 50, the cable connection between the circuit board 20 and the wireless display screen 40 can be eliminated, making the wireless hysteroscope 100 with screen of this invention convenient to use and suitable for rapid examination and treatment in outpatient settings; at the same time, since the wireless display screen 40 is detachably mounted on the handle 10, it is easy to disassemble or assemble the wireless display screen 40. Therefore, after the wireless hysteroscope 100 with screen of this invention is used, the wireless display screen 40 can be removed for reuse, and the rest can be discarded.

[0046] It is worth noting that, since the wireless display screen 40 and the wireless module 50 are wirelessly connected, the wireless display screen 40, in addition to having a display unit, also has a receiving module. The specific wireless communication between the receiving module and the wireless module 50 is a well-known technology and will not be elaborated upon here.

[0047] It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
