[0030] The following is a further non-restrictive detailed description of the utility model technical solution in conjunction with the preferred embodiment and its accompanying drawings. In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings. In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0031] like Figure 1-Figure 7 As shown, a hysteroscope according to an embodiment of the utility model comprises an insertion portion 1, a handle portion 2 and a display device 5. The insertion portion 1 comprises an insertion tube 10 and a light source 12 and a camera 13 fixed to the front end of the insertion tube 10; the handle portion 2 is arranged at a certain angle with the insertion portion 1, and the handle portion 2 comprises a housing 20 and a circuit board 21 arranged inside the housing 20, the circuit board 21 is electrically connected to the light source 12 and the camera 13 at the same time, and the display device 5 is electrically connected to the circuit board 21. When in use, the doctor holds the handle portion 2, and the insertion tube 10 of the insertion portion 1 needs to be inserted into the body to observe the situation inside the body. During use, the light source 12 at the end of the insertion tube 10 is used for auxiliary lighting, and the camera 13 at the end of the insertion tube 10 is used to capture images, and the captured image information can be transmitted back to the circuit board 21, and transmitted by the circuit board 21 to the display device 5 for observation by medical staff.

[0032] like Figure 1 As shown, the insertion tube 10 is provided with a water inlet channel and a water outlet channel along its axial direction, and the hysteroscope also includes a uterine distension pump, a water inlet pipe 22 and a water outlet pipe 23. One end of the water inlet pipe 22 is connected to the water inlet channel and the other end is connected to the uterine distension pump. The water outlet pipe 23 is connected to the water outlet channel for discharging the uterine distension fluid in the patient's body. The water inlet pipe 22 and the water outlet pipe 23 are both located outside the housing 20. By arranging the waterway of the water inlet pipe 22 and the water outlet pipe 23 outside the housing 20, and the circuit board 21 inside the housing 20, the two are completely separated in space, eliminating the risk of short circuit of the circuit board 21 caused by water leakage in the waterway. At the same time, there is no need to make additional waterproof design for the circuit board 21, which reduces the production cost.

[0033] In order to ensure that the weight is equal when held by the doctor, in this embodiment, the water inlet pipe 22 and the water outlet pipe 23 are respectively arranged on opposite sides of the housing 20. Further, the water inlet pipe 22 and the water outlet pipe 23 are symmetrically arranged on opposite sides of the housing 20.

[0034] In this embodiment, the water inlet pipe 22 and the water outlet pipe 23 are both clamped on the outer side of the housing 20. Specifically, the housing 20 is provided with a receiving groove 200 for accommodating the water inlet pipe 22 and the water outlet pipe 23. By providing the receiving groove 200 to accommodate the water inlet pipe 22 and the water outlet pipe 23, and the water inlet pipe 22 and the water outlet pipe 23 are not higher than the outer surface of the housing 20, it is prevented that the water inlet pipe 22 and the water outlet pipe 23 protrude from the outer surface of the housing 20, which affects the hand-holding feeling of the doctor.

[0035] The water inlet pipe 22 and the water outlet pipe 23 are both elastic hoses, and the opening of the storage tank 200 has a closing structure (not shown in the figure) to limit the water inlet pipe 22 and the water outlet pipe 23. During installation, since the water inlet pipe 22 and the water outlet pipe 23 are both elastic hoses, they can be manually pressed into the storage tank 200, and the water inlet pipe 22 and the water outlet pipe 23 are limited by the closing structure to prevent the water inlet pipe 22 and the water outlet pipe 23 from being separated from the storage tank 200.

[0036] The end of the insertion tube 10 is provided with a water inlet hole and a water outlet hole, a water inlet joint 15 and a water outlet joint 16 are fixed on the insertion part 1, the two ends of the water inlet channel are respectively connected to the water inlet hole and the water inlet joint 15, the two ends of the water outlet channel are respectively connected to the water outlet hole and the water outlet joint 16, the water inlet pipe 22 is connected to the water inlet joint 15, and the water outlet pipe 23 is connected to the water outlet joint 16. In this embodiment, the water inlet joint 15 and the water outlet joint 16 are located on the same side of the insertion part 1.

[0037] like Figure 3-Figure 6 As shown, in this embodiment, the insertion part 1 and the handle part 2 are detachably connected. The doctor holds the handle part 2, so the handle part 2 does not need to be inserted into the human body, while the insertion part 1 needs to be inserted into the body to observe the internal conditions. After completing an examination, the medical staff disconnects the connection between the insertion part 1 and the handle part 2, and removes the insertion part 1 from the handle part 2. Then, the used insertion part 1 is discarded, and the handle part 2 is disinfected for reuse. Before the next use, a new insertion part 1 is connected to the disinfected handle part 2 to perform the next examination. Through the detachable connection between the handle part 2 and the insertion part 1, cross infection to the patient can be avoided, and the use cost can also be saved.

[0038] The housing 20 is provided with a first matching portion 201 , the inserting portion 1 includes a shell 17 , and the shell 17 is provided with a second matching portion 170 . The first matching portion 201 and the second matching portion 170 are detachably connected.

[0039] The second matching portion 170 defines a matching groove 171 that matches with the first matching portion 201 . A pair of elastic buckles 172 are formed on the sidewalls of the matching groove 171 . A slot 202 that matches with the elastic buckle 172 is defined on the outer sidewall of the first matching portion 201 .

[0040] A first coupler 3 is fixed on the first matching portion 201, and the first coupler 3 is electrically connected to the circuit board 21. A second coupler 4 is fixed on the second matching portion 170, and the second coupler 4 is electrically connected to the light source 12 and the camera 13 at the same time. When the first matching portion 201 is connected to the second matching portion 170, the first coupler 3 is coupled to the second coupler 4.

[0041] During use, the first connection part 201 and the second connection part 170 need to be connected first. At the same time, the first coupler 3 and the second coupler 4 are coupled to each other, and the camera 13 at the end of the insertion tube 10 is connected to the circuit board 21 in the housing 20. The image information captured by the camera 13 can be transmitted back to the circuit board 21, and then transmitted to the display device 5 by the circuit board 21 for medical staff to observe. After completing an examination, the medical staff disconnects the connection between the first connection part 201 and the second connection part 170, and removes the insertion part 1 from the handle part 2. Then, the used insertion part 1 is discarded, and the handle part 2 is disinfected for reuse. Before the next use, a new insertion part 1 is connected to the disinfected handle part 2, so as to perform the next examination. In this way, the detachable connection between the first connection part 201 and the second connection part 170 is used to realize the detachable connection between the handle part 2 and the insertion part 1, which can avoid cross infection to the patient and save the use cost.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
