[0002] The electronic hysteroscope is a disposable diagnostic and treatment instrument for the uterus. When in use, the cannula of the electronic hysteroscope needs to be inserted into the uterine cavity to obtain the location of the lesion, and diagnose and treat the lesion.

[0003] The electronic hysteroscopes on the market can be divided into straight-tube electronic hysteroscopes and curved-tube electronic hysteroscopes according to the shape of the cannula; the cannula of the straight-tube electronic hysteroscope is straight, and its advantage is that it can meet the operation requirements of larger-sized surgical instruments; the cannula of the curved-tube electronic hysteroscope is curved at the front end, and its advantage is that it is convenient to drive the lens to rotate by rotating the cannula to increase the observation field, but due to the curved front end of the cannula, it is not convenient for larger-sized surgical instruments to pass through, and can only meet the operation requirements of smaller-sized surgical instruments. When designing and developing existing electronic hysteroscopes, the corresponding shell is designed separately according to the type of cannula to meet the installation and connection requirements of the corresponding type of cannula, which not only increases the shell development cost of the electronic hysteroscope, but also requires different shell production molds when it is put into production later, which increases the design and manufacturing costs of the manufacturer, which is not conducive to reducing the ex-factory cost of the electronic hysteroscope.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0037] The electronic hysteroscope of the present application is a disposable item. When using it, the end of the cannula away from the outer shell 100 must first be inserted into the uterine cavity to diagnose the location of the lesion in the uterus using the camera assembly 600; then, the corresponding surgical instrument is selected according to the diagnosis, and the surgical instrument is passed through the outer shell 100 and inserted into the uterus through the cannula for treatment. For the convenience of description, the present application defines the height direction of the outer shell 100 as the up and down direction, the width direction of the outer shell 100 (i.e., the closing and docking direction of the two half shells 100a) as the left and right direction, and the length direction of the outer shell 100 (i.e., the direction in which the cannula is inserted into the outer shell 100) as the front and back direction; based on this, Figure 4 and Fig.12 In the figure, the upper side and the lower side of the paper are the rear direction and the front direction respectively, the left side and the right side of the paper are the upper direction and the lower direction respectively, and the outer side and the inner side of the paper are the left direction and the right direction respectively.

[0038] like Figure 1 , Figure 2 , Figure 4 and Fig.12 As shown, the electronic hysteroscope involved in the present application includes a housing 100 and a diagnosis and treatment module 300 detachably mounted on the housing 100; the diagnosis and treatment module 300 is a curved tube type diagnosis and treatment module or a straight tube type diagnosis and treatment module; different types of electronic hysteroscopes can be formed by mounting different types of diagnosis and treatment modules on the housing 100. In order to facilitate the installation of different types of diagnosis and treatment modules, the housing 100 needs to be formed by two half shells 100a being butted together.

[0039] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig.10 As shown, the curved tube type diagnosis and treatment module includes a first cannula 310a, a first rear adapter 320a and a first knob 330a which are connected in sequence from front to back; wherein the first cannula 310a, the first rear adapter 320a and the first knob 330a are all hollow structures and are connected in sequence to form a first instrument channel, which can be used as an insertion channel for surgical instruments; one end of the first cannula 310a is curved and is equipped with a camera assembly 600; the other end of the first cannula 310a extends into the housing 100 and is connected to the first rear adapter 320a; the outer A first annular clip is formed inside the shell 100, and a second annular clip that cooperates with the first annular clip is formed on the first rear adapter 320a; the first rear adapter 320a is detachably connected to the outer shell 100 through the clip-fitting of the second annular clip and the first annular clip; in this way, when the first knob 330a is rotated to make the first rear adapter 320a rotate, the first tube 310a will rotate accordingly to change the shooting angle of the camera assembly 600 on the first tube 310a, thereby conveniently increasing the shooting field of view of the camera assembly 600.

[0040] like Figure 2 , Figure 3 , Fig.12 , Fig.13 and Fig.14 As shown, the straight tube type diagnosis and treatment module includes a second cannula 310b, a second rear adapter 320b and a second knob 330b connected in sequence from front to back; wherein, the second cannula 310b, the second rear adapter 320b and the second knob 330b are all hollow structures and are connected in sequence to form a second instrument channel, which can be used as an insertion channel for surgical instruments; the second cannula 310b is in a straight line, and a camera assembly 600 is installed at one end of the second cannula 310b; the other end of the second cannula 310b extends into the housing 100 and is connected to the second rear adapter 320b; a second annular clamping piece is formed on the second rear adapter 320b to match the first annular clamping piece in the housing 100. In this way, the detachable rotation connection between the first rear adapter 320a and the housing 100 can be achieved. Since the second insert tube 310b does not need to rotate, an anti-rotation structure may be optionally provided to limit the rotation of the second rear rotation joint 320b; the anti-rotation structure includes a first anti-rotation component and a second anti-rotation component that cooperate with each other, the second anti-rotation component is arranged on the second rear rotation joint 320b, the first anti-rotation component is arranged in the housing 100, and the first anti-rotation component does not affect the free rotation of the first rear rotation joint 320a.

[0041] Since both the curved tube type diagnosis and treatment module and the straight tube type diagnosis and treatment module can be installed in the outer shell 100 through corresponding adapters, the manufacturer only needs to develop and produce one outer shell 100 to realize the production of two types of electronic hysteroscopes, effectively reducing the factory cost of the electronic hysteroscope and improving market competitiveness.

[0042] It can be understood that the first annular clamping member and the second annular clamping member are an annular clamping block 410 and an annular clamping groove 420 that cooperate with each other; that is, when the first annular clamping member is an annular clamping block 410, the second annular clamping member is an annular clamping groove 420 or when the first annular clamping member is an annular clamping groove 420, the second annular clamping member is an annular clamping block 410; the first anti-rotation member and the second anti-rotation member are an anti-rotation clamping groove 510 and an anti-rotation protrusion (not shown in the figure) that cooperate with each other or two An anti-rotation plane; that is, when the first anti-rotation component is an anti-rotation slot 510, and the second anti-rotation component is an anti-rotation protrusion, at this time, the anti-rotation slot 510 can be opened on the inner wall of the first annular clamping component or directly set on the inner wall of the outer shell 100; when the first anti-rotation component is an anti-rotation protrusion and the second anti-rotation component is an anti-rotation slot 510, in order to avoid the anti-rotation protrusion interfering with the smooth rotation of the first rear rotation joint 320a, the anti-rotation protrusion needs to be directly set on the inner wall of the outer shell 100 next to the first annular clamping component.

[0043] like Figure 1 and Figure 2As shown, in order to facilitate the user to hold and operate, the two half shells 100a are preferably gun-shaped half shells, and the two gun-shaped half shells are detachably connected to form a shell 100 having a head shell and a handle shell; the diagnostic module 300 is installed on the head shell of the shell 100.

[0044] Furthermore, in order to ensure the stability of holding, Figure 1 As shown, an anti-slip groove 110 may be opened on the handle shell of the housing 100 .

[0045] It is understandable that the camera assembly 600 of the electronic hysteroscope can be controlled and transmitted with the shooting content by wired or wireless (such as Bluetooth, Wifi). Based on the convenience of operation, the present embodiment preferably installs a camera control board 700 electrically connected to the camera assembly 600 in the handle shell of the housing 100, and sets a control button 720 connected to the camera control board 700 on the handle shell, so as to control the state of the camera assembly 600 by using the control button 720, that is, to control the camera assembly 600 to be in a working state (including a photographic state and / or a photographing state) or a shutdown state. In addition, a connecting plug 710 is also provided at the bottom of the handle shell, and the connecting plug 710 is used for the electrical connection between the camera control board 700 and an external device, so as to transmit the content shot by the camera assembly 600 to an external device for display.

[0046] In order to meet the insertion requirements of surgical instruments of different sizes and minimize the pain of patients, hospitals usually equip electronic hysteroscopes with cannulas of different outer diameters. In order to adapt to cannulas of different outer diameters and avoid excessive shaking of the cannulas in the housing 100, such as Figure 2 , Figure 4 and Fig.11 As shown, a front support seat 430 is formed in the outer shell 100, and a through hole is provided on the front support seat 430 for the insertion of the cannula; if the size difference between the inner diameter of the through hole and the outer diameter of the cannula is greater than a preset value, a front adapter 370 with a different inner hole size can be optionally installed in the through hole of the front support seat 430 to adapt to cannulas of different sizes.

[0047] Specifically, Fig.11 and Fig.16 As shown, a mounting slot is formed on the inner wall of the front support seat 430, and a mounting block 371 that cooperates with the mounting slot is formed on the outer wall of the front adapter 370; through the cooperation between the mounting slot and the mounting block 371, the front adapter 370 is installed on the front support seat 430 in a non-axially movable and non-rotatable manner, thereby realizing the detachable installation of front adapters 370 of different specifications.

[0048] In order to better obtain the condition of intrauterine lesions, the diagnostic module 300 usually has a dual water system to realize the irrigation function. At this time, the shell 100 is equipped with an inlet valve 210 and an outlet valve 220; the inlet valve 210 and the outlet valve 220 are preferably arranged on the head shell, and are respectively located above and below the head shell, and the horizontal distance from the outlet valve 220 to the handle shell is greater than the horizontal distance from the inlet valve 210 to the handle shell, so as to ensure that there is enough space for the operator to hold the handle shell.

[0049] like Figures 3 to 9 As shown, the curved tube type diagnosis and treatment module also includes a main body component 360, and the first cannula 310a is connected to the first rear adapter 320a through the main body component 360; wherein, a first inner tube 350a is arranged inside the first cannula 310a, and the diameter of the first inner tube 350a is smaller than the diameter of the first outer tube 310a, so that a first water inlet channel is formed between the first cannula 310a and the outside of the first inner tube 350a; the front end of the first cannula 310a is provided with a water inlet 311 connected to the first water inlet channel and a water inlet 312 connected to the first inner tube 350a. The main assembly 360 includes a water separator 361 and a water separator sleeve 362 disposed outside the water separator 361; the water separator sleeve 362 can rotate relative to the water separator 361, and the first insert pipe 310a is connected to the first rear adapter 320a through the water separator 361; the outer side of the water separator 361 is provided with a water inlet groove 3611 and a water outlet groove 3612, and the water separator sleeve 362 is provided with a first water inlet pipe 3621 connecting the water inlet groove 3611 and the water inlet valve 210 and a first water outlet pipe 3621 connecting the water outlet groove 3612 and the water outlet pipe 3621 connecting the water inlet groove 3611 and the water inlet valve 210. The first water outlet pipe 3622 of the water outlet valve 220; the water divider 361 is provided with a first insertion hole 3613 for inserting the first insertion pipe 310a and a first inner tube hole 3614 for inserting the first inner tube 350a; the hole wall of the first insertion hole 3613 is provided with a first water inlet hole 3615 connected to the water inlet groove 3611, and the hole wall of the first inner tube hole 3614 is provided with a first water outlet hole 3616 connected to the water outlet groove 3612; in this way, the water of the water inlet valve 210 will flow into the water inlet groove along the first water inlet pipe 3621 3611, and then enter the first insertion tube hole 3613 through the first water inlet hole 3615, and then flow to the water inlet 311 along the first water inlet channel to complete the filling of the uterine cavity; at the same time, the water in the uterine cavity will flow into the first inner tube 350a along the return water port 312, and then enter the first inner tube hole 3614 and flow to the water outlet groove 3612 through the first water outlet hole 3616, and the water in the water outlet groove 3612 will flow to the water outlet valve 220 through the first water outlet pipe 3622 to complete the discharge of the liquid in the uterine cavity. When the outer diameter of the first insertion tube 310a is small, resulting in a small size of the water inlet 311 affecting the filling efficiency, a water supply port connected to the first water inlet channel can be opened on the front end outer wall of the first insertion tube 310a.

[0050] like Figure 4 , Figure 6 and Figure 7 As shown, three sealing grooves 318 are arranged outside the water divider 361, and the three sealing grooves 318 and the two water grooves of the water inlet groove 3611 and the water outlet groove 3612 are arranged alternately in the axial direction of the water divider 361; a sealing ring 363 is installed in the sealing groove 318; the water divider sleeve 362 is inserted into the outside of the water divider 361 and cooperates with each sealing ring 36 to realize the axial sealing of the water inlet groove 3611 and the water outlet groove 3612. At this time, the water divider 361 can rotate relative to the water divider sleeve 362. When the main assembly 360 is installed, in order to limit the axial movement of the water divider sleeve 362, an axial limiting structure that limits the axial movement of the water divider sleeve 362 can be formed in the outer shell 100. In addition, in order to avoid affecting the axial sealing of the water inlet groove 3611 and the water outlet groove 3612, it is necessary to limit the axial movement of the water divider 361 relative to the water divider sleeve 362.

[0051] Specifically, the axial limiting structure includes a first limiting baffle plate in contact with the front end of the water dividing sleeve 362 and a second limiting baffle plate in contact with the rear end of the water dividing sleeve 362. The first limiting baffle plate cooperates with the second limiting baffle plate to limit the axial movement of the water dividing sleeve 362. Of course, a third limiting baffle plate can also be added to the housing 100, and the first limiting baffle plate and the third limiting baffle plate are used to limit the axial movement of the water divider 361; based on the convenience of installation, this embodiment preferably forms a front stopper at the front end of the water dividing sleeve 362, the front stopper plate contacts the first limiting baffle plate, and the front stopper plate cooperates with the second limiting baffle plate to limit the axial movement of the water divider 361.

[0052] like Figure 3 , Fig.12 , Fig.13 , Fig.14 and Fig.15As shown, for the straight tube type diagnosis and treatment module, a second inner tube 350b is provided in the second cannula 310b, and the diameter of the second inner tube 350b is smaller than the diameter of the second cannula 310b, so as to form a second water inlet channel between the second cannula 310b and the second inner tube 350b; a water inlet 311 connected to the second water inlet channel and a water return port 312 connected to the second inner tube 350b are provided at the front end of the second cannula 310b; a second cannula hole 3201b for inserting the second cannula 310b and a second inner tube hole 3202b for inserting the second inner tube 350b are provided in the second rear adapter 320b, and a second water inlet pipe 3203b connecting the second cannula hole 3201b and the water inlet valve 210 and a second water outlet pipe 3204b connecting the second inner tube hole 3202b and the water outlet valve 220 are provided on the second rear adapter 320b. In this way, the second cannula 310b is connected to the second water inlet pipe 3203b through the second cannula hole 3201b, and the second inner tube 350b is connected to the second water outlet pipe 3204b through the second inner tube hole 3202b. When in use, the water of the water inlet valve 210 will enter the second cannula hole 3201b along the second water inlet pipe 3203b, and then flow to the water inlet 311 along the second water inlet channel to complete the liquid filling action of the uterine cavity; at the same time, the water in the uterine cavity will also flow into the second inner tube 350b along the return water port 312, and then enter the second inner tube hole 3202b and flow to the water outlet valve 220 through the second water outlet pipe 3204b to complete the discharge action of the liquid in the uterine cavity. When the outer diameter of the second cannula 310b is small, resulting in a small size of the water inlet 311 affecting the liquid filling efficiency, a water supply port connected to the second water inlet channel can be opened on the front end outer wall of the second cannula 310b.

[0053] In order to prevent the liquid refluxing from the uterine cavity from being discharged from the knob through the instrument channel and contaminating the operator, a one-way sealing valve 340 is required to be set between the first rear adapter 320a and the first knob 330a, and between the second rear adapter 320b and the second knob 330b, and the one-way sealing valve 340 is provided with a sealing port for surgical instruments to pass through.

[0054] When the camera assembly 600 is connected to the camera control board 700 through a wire, the water divider 361 and the second rear adapter 320b must be provided with a wire outlet hole 3617 for the wire to pass through; in this way, the end of the wire that is guided away from the camera assembly 600 can enter the water divider 361 or the second rear adapter 320b along the first insert tube 310a and pass through the wire outlet hole 3617 to the camera control board 700; in order to prevent liquid from flowing out of the wire outlet control 3617, a wire sealing device must be provided at the wire outlet hole 3617 to seal the gap between the wire and the wire outlet hole 3617; since the wire sealing device is a prior art, it will not be described in detail.
