Detailed Description

The invention will be further illustrated and understood by the following non-limiting examples.

As shown in fig. 1-3, the present invention is a soft electronic hysteroscope, comprising: the imaging module seat and the operating part are the prior art, and an optical imaging device and a light source are arranged in the imaging module seat; operation portion, operation portion pass through rigid connection spare connect in the end of insertion portion 1, operation portion includes handle 2 and the hand (hold) 3 that becomes certain angle with this handle 2, handle 2 and 3 fixed connection of hand (hold) and formation pistol form, wherein, 2 end last apparatus that are equipped with of handle are gone into mouth 21, the bottom of hand (hold) 3 is equipped with into water base 31 and play water base 32, it all with 3 fixed connection of hand (hold) to advance water base 31 and play water base 32, it is provided with the knob to rotate on the hand (hold) 3, the knob passes through wire and pulls 1 front end 11 of insertion portion, through the rotation of the steerable front end 11 of rotatory knob, the minimum contained angle that steerable front end 11 and inserted pipe center pin can reach 20.

The handle 3 is also fixedly provided with a signal connector 33 electrically connected with the optical imaging device; the signal connector 33 is used to connect the optical imaging device with an image processing device, which displays the generated image data on a monitor.

The invention improves the relationship between the insertion tube and the insertion tube, the water inlet base 31, the water outlet base 32 and the instrument inlet 21. The insertion tube comprises a front end head 11 and a rear end stainless steel inner tube 12, the outer layer of the insertion tube is wrapped by soft leather, and the stainless steel inner tube 12 and the front end head 11 are fixed in the inner wall of the soft leather.

The front end tip 11 of the insertion tube is made of a softer medical-grade PVDF material which has high surface fitting degree with a patient, and cannot cause harm to the patient and cause discomfort to the patient. Because the front end can rotate at will and feel softer, it is convenient for observe everywhere in the cavity, reduces and observes the dead angle. The stainless steel inner tube 12 facilitates access to the patient.

The front end of the insert pipe is provided with two water inlets 4 and one water outlet 5, the two water inlets 4 and the one water outlet 5 form a triangular area, the cover plate 6 of the imaging module base is positioned at the central position in the triangular area, namely the two water inlets 4 are positioned at symmetrical positions above the cover plate 6, at the moment, the cover plate 6 is positioned in the spraying range of the liquid spraying of the water inlets 4, the water inlet base 31 is communicated with the two water inlets 4 through water inlet channels which are arranged inside the handle 3 and in the inner cavity of the insert pipe in a penetrating manner, the arrangement of the two water inlets 4 can greatly improve the water inflow, is beneficial to increasing the frequency of water circulation, improves the cleaning efficiency and saves the cleaning time; simultaneously, water inlet 4 can wash the adnexed mucus on the cover plate 6 of formation of image module group seat clean in the cleaning process, avoids appearing the cover plate 6 of ready-made formation of image module group seat because attached to lead to image shadow, blurred phenomenon by the filth.

The water outlet base 32 is communicated with the water outlet 5 through a water outlet channel 8 which is arranged in the handle 3 and in the inner cavity of the insertion tube in a penetrating way, and the instrument inlet 21 is communicated with the water outlet 5 through an instrument channel 7 which is arranged in the handle 2 and in the inner cavity of the insertion tube in a penetrating way; the instrument channel 7 and the water outlet channel 8 share one pipeline, the pipeline is provided with two branch pipes in a three-way valve shape, the two branch pipes are respectively a first branch pipe and a second branch pipe, the first branch pipe is communicated to the instrument inlet 21, and the second branch pipe is communicated to the water outlet base 32. One end of the first branch pipe close to the instrument inlet 21 is provided with a liquid check valve 71, and the liquid check valve 71 ensures that the instrument channel 7 at the rear end of the handle 2 and the outlet channel at the lower end of the handle 3 are independent and do not influence each other.

Because the instrument channel 7 and the water outlet channel 8 adopt the uniform channel, if the outer diameter of the insertion tube in the prior art is kept unchanged, the maximum inner diameters of the instrument outlet and the water outlet 5 can be further increased. That is, the maximum inner diameter of the outlet sharing the same pipe can be enlarged to 2mm, in the present invention, the maximum inner diameter of the outlet sharing the same pipe is preferably 2mm, and the inner diameters of the instrument pipe and the water pipe are maximized without increasing the outer diameter of the insertion pipe, so that it is convenient to insert various medical instruments of different sizes by matching the design of the two water inlets 4, and the range of applicable medical instruments can be enlarged.
