It includes a hysteroscope, an energy system, a light source system, a perfusion system and an imaging system. It uses the front part of the scope to enter the uterine cavity, which has a magnifying effect on the observed area. It is the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions because of its intuitiveness and accuracy. When in use, the hysteroscope is inserted into the human uterine cavity, and then the light source is turned on to obtain images inside the cavity, so as to diagnose the disease based on the images. The uterus needs to be inflated with fluid for easy observation.

[0003] Existing hysteroscopes have poor support and sealing effects for patients with loose cervical os, which easily causes leakage of irrigation fluid; and if the leakage cannot be handled in time, it will cause contamination to the patient's body or the examination instrument.

DETAILED DESCRIPTION

[0020] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Figure 1-Figure 2 As shown in the figure, a leak-proof hysteroscope for obstetrics and gynecology is provided, including a scope tube 10 and a signal interface 11 at the end of the scope tube 10, an extrusion assembly is installed on the scope tube 10, a filling interface 32 is provided between the signal interface 11 and the extrusion assembly, the extrusion assembly includes an extrusion airbag 16 and an inflation bag 23, a locking airbag 17 is fixedly provided on the side of the extrusion airbag 16 close to the signal interface 11, the locking airbag 17 and the extrusion airbag 16 are both slidably sleeved on the scope tube 10, the locking airbag 17 and the extrusion airbag 16 are connected to the inflation bag 23 through an air pipe, a one-way valve is installed on the air pipe, a leakage mesh 30 is provided on the other side of the extrusion airbag 16, and a drainage pipe 31 is installed at the bottom of the leakage mesh 30.

[0022] The leaking mesh 30 is a texture structure provided on the side surface of the extruded airbag 16 . The texture structure of the leaking mesh 30 provides a channel for the leaking liquid to flow downward, and the leaking liquid is gathered at the bottom and discharged through the drain pipe 31 .

[0023] The signal interface 11 includes a camera system interface 12 and an optical fiber interface 13 provided on the mirror tube 10 . The signal interface 11 detects or collects images of the patient by connecting to corresponding equipment.

[0024] The filling interface 32 includes a filling inlet 14 and a filling outlet 15 opened on the mirror tube 10. The filling inlet 14 is used to inject the filling liquid into the patient's body, which is convenient for the subsequent insertion of the mirror tube 10 for observation; when the filling liquid is excessive or used up, it is discharged through the filling outlet 15.

[0025] It should be noted that the locking airbag 17 is an airbag of a cylindrical structure. The locking airbag 17 and the squeezing airbag 16 are fixedly connected to each other, and the inflation of the two is controlled separately through different air pipes. Both are slidably mounted on the mirror tube 10, and their positions on the mirror tube 10 are adjusted according to different needs. By inflating the inside of the locking airbag 17, the locking airbag 17 and the squeezing airbag 16 are fastened relative to the mirror tube 10.

[0026] The locking airbag 17 has several protrusions inside, which is beneficial to increase the friction between the locking airbag 17 and the mirror tube 10 and play a stabilizing role.

[0027] The extrusion airbag 16 includes a conical section 26, a convex section 27, an extrusion section 28 and a sealing section 29 which are connected in sequence, and the conical section 26 is located on the side away from the signal interface 11, the outer circumferential size of the convex section 27 is larger than the conical section 26 and the extrusion section 28, and the outer circumferential size of the sealing section 29 is larger than the convex section 27; the leak mesh 30 is located on the sealing section 29.

[0028] When the squeezing airbag 16 is extended into the patient's cervical opening, the conical section 26 first enters the patient's body, and then the convex section 27 and the squeezing section 28 enter, and the sealing section 29 is close to the outer wall of the patient's cervix to inflate the squeezing airbag 16. The sealing section 29 and the convex section 27 are filled and fitted to the outside and inside of the patient's cervical opening to play a role of sealing and fixing; the leak mesh 30 is located on the sealing section 29 and is close to the outer wall of the patient's cervix. When the irrigation liquid leaks out, the leak mesh 30 will play a role of collecting it, so that the collected irrigation liquid is drained through the drainage pipe 31 at the bottom to prevent the irrigation liquid from contaminating the patient's body or the detection instrument.

[0029] The leakage mesh 30 adopts a concave arc surface structure, which is in better contact with the patient's body and forms a seal on the surrounding area, so that the leaked irrigation liquid enters the drainage pipe 31 at the bottom, reducing the risk of external leakage.

[0030] A linear bearing 25 is sleeved inside the squeezing airbag 16 , and the linear bearing 25 is slidably mounted on the mirror tube 10 , so that the position of the squeezing airbag 16 on the mirror tube 10 can be conveniently adjusted according to the needs of different patients or changes in the observation position.

[0031] When installing the linear bearing 25, insert the linear bearing 25 from the inner hole of the locking airbag 17, further enter the interior of the extrusion airbag 16, and then insert the mirror tube 10 into the linear bearing 25, and the mirror tube 10 passes through the extrusion airbag 16. A sliding seal is used at the contact point between the mirror tube 10 and the extrusion airbag 16 to prevent the filling liquid from flowing out.

[0032] Furthermore, the air pipe includes a main air pipe 18, a first branch pipe 19 and a second branch pipe 20, and the one-way valve includes a first one-way valve 21 and a second one-way valve 22; the inflatable bag 23 is connected to one end of the main air pipe 18, and a conversion valve 24 is installed at the other end of the main air pipe 18. The conversion valve 24 is divided into two branches, branch one is connected to the locking air bag 17 through the first branch pipe 19, and branch two is connected to the extrusion air bag 16 through the second branch pipe 20. The first one-way valve 21 is installed on the first branch pipe 19, and the second one-way valve 22 is installed on the second branch pipe 20.

[0033] The first one-way valve 21 and the second one-way valve 22 both allow the gas from the inflation bag 23 to pass through into the squeezing airbag 16 and the locking airbag 17, but not the reverse direction.

[0034] When it is necessary to inflate and fix, the inflatable bag 23 is squeezed repeatedly to make the gas enter the locking bag 17 or the squeezing bag 16, wherein any branch is selected by adjusting the switching valve 24. The locking bag 17 is adjusted to deflate by adjusting the first one-way valve 21, and the squeezing bag 16 is adjusted to deflate by adjusting the second one-way valve 22 to make it loose, so as to facilitate movement or disassembly.

[0035] When using,

[0036] First, the air pressure in the squeezing airbag 16 and the locking airbag 17 is released, and the relative position of the squeezing assembly on the mirror tube 10 is adjusted and determined according to the patient's needs;

[0037] Secondly, the squeezing airbag 16 is inserted into the patient's cervical opening, and the squeezing airbag 16 is inflated by repeatedly squeezing the inflation bag 23, so that the squeezing airbag 16 expands and fits the patient's cervical opening, and then the switching valve 24 is adjusted to inflate the locking airbag 17 to fix it to the endoscope tube 10;

[0038] Next, the irrigation liquid is introduced through the irrigation liquid inlet 14, and the hysteroscope is used to observe or collect images;

[0039] When the filling liquid flows out, the filling liquid will be collected into the drain pipe 31 at the bottom of the leaking mesh 30 through the leaking mesh 30, and the other end of the drain pipe 31 is connected to the pipeline for discharge, so as to avoid the filling liquid from contaminating the human body or the detection instrument;

[0040] Finally, after the observation or image acquisition is completed, the filling liquid is discharged through the filling outlet 15; the first one-way valve 21 and the second one-way valve 22 are released to allow the gas in the squeezing airbag 16 and the locking airbag 17 to escape, and the squeezing airbag 16, the mirror tube 10 and other instruments are taken out.

[0041] The utility model uses the above embodiments to illustrate the technical concept of the utility model, but the utility model is not limited to the above embodiments, that is, it does not mean that the utility model must rely on the above embodiments to be implemented. Those skilled in the art should understand that the relevant improvements to the utility model fall within the protection scope and disclosure scope of the utility model.
