[0002] Endoscope is an important diagnosis and treatment tool in modern medicine, and is widely used in various minimally invasive surgeries and examinations. Its structure is complex, especially the internal structure of the channel, which makes cleaning a key problem. The existing endoscope cleaning technology mainly focuses on the lens and the instrument channel.

[0003] The lens is relatively easy to clean, usually relying on manual wiping or soaking chemical cleaning agent. The instrument channel cleaning method mainly has two kinds: one is through water flushing, and the other is using a scraper for mechanical cleaning (for example, Chinese patent CN205585980U granted on September 21, 2016). However, the efficiency of water flushing is low, and it is usually difficult to completely remove high adhesion dirt, while the mechanical structure such as scraper is easy to scratch or scratch the inner wall of the instrument channel.

[0004] There are also some cleaning equipment with ultrasonic function on the market, but most of these devices are immersion cleaning (the endoscope is put into the ultrasonic liquid environment as a whole), but in order to protect the lens fiber, it cannot use large ultrasonic power, so the cleaning effect of the instrument channel is also limited, and it is difficult to meet the requirement of thorough cleaning.

[0032] Example 1

[0033] As Figures 1-9 shown, the utility model provides a kind of endoscope cleaning device, including inlet plug 2 and outlet plug 3, the size of inlet plug 2 can be inserted and the entrance end of instrument channel 101 is closed, the size of outlet plug 3 can be inserted and the outlet end of instrument channel 101 is closed, inlet plug 2 is fixedly connected with ultrasonic transducer 4;Washing channel 201 is opened in inlet plug 2, the downstream end of washing channel 201 is located the end surface of inlet plug 2 inserted instrument channel 101, the upstream end of washing channel 201 is passed through inlet plug 2 and is communicated with cleaning pump 4.Ultrasonic transducer 4 is connected at the end of inlet plug 2 away from instrument channel 101.

[0034] Specifically, the inlet plug 2 and the outlet plug 3 are both cylindrical structural members, and the inlet plug 2 and the outlet plug 3 are tapered circular table structures near / inserted into one end of the instrument channel 101 of the endoscope 1, so as to improve the sealing performance. The inlet plug 2 and the outlet plug 3 are both metal materials, have good corrosion resistance, and the end of the inlet plug 2 is fixedly connected with the ultrasonic transducer 4, so that the ultrasonic energy can be directly transmitted to the cleaning liquid in the instrument channel 101. The ultrasonic transducer is used to convert the input electric power into mechanical power (i.e. ultrasonic wave) and then transmit it out, which belongs to the prior art content, and the structure principle will not be described here. The cleaning pump 4 is used to pressurize and transport the cleaning liquid, and the pump device in the prior art can be directly used, and the structure principle will not be described here. The cleaning pump 4 can be connected to the end of the ultrasonic transducer 4 away from the inlet plug 2 (the device has higher integration), or can be separately arranged from the ultrasonic transducer 4.

[0035] The cleaning channel 201 in the inlet plug 2 is entirely opened along the axial direction of the inlet plug 2 (but not completely parallel to the axial direction, which is specifically described in Embodiment 2). Thus, when the inlet plug 2 is inserted into the instrument channel 101, the cleaning liquid is sprayed into the instrument channel 101 along the cleaning channel 201 after being pressurized by the cleaning pump 4.

[0036] In the ordinary cleaning mode, the device only needs to be inserted into the inlet plug 2, and the cleaning liquid is sprayed from the cleaning channel 201 on the end surface of the inlet plug 2, which washes the inner wall of the instrument channel 101 of the endoscope 1 and flows out from the outlet of the instrument channel 101 of the endoscope 1, thereby flushing the instrument channel 101.

[0037] In the high-efficiency cleaning mode, the inlet plug 2 is inserted and the cleaning liquid is injected, and then the outlet plug 3 is inserted into the outlet end of the instrument channel 101 to make the instrument channel 101 full of cleaning liquid and keep sealed, and then the ultrasonic transducer 4 is turned on, so that the ultrasonic energy is transmitted to the cleaning liquid in the instrument channel 101 along the inlet plug 2, and the cleaning liquid can transmit the ultrasonic energy to strip the adhered dirt on the inner wall of the instrument channel 101. After a period of time, the outlet plug 3 is opened to discharge the cleaning liquid and the dirt.

[0038] The device can perform ultrasonic cleaning on the inside of the instrument channel 101 alone, without the need to put the endoscope 1 into the ultrasonic liquid environment, and can use a larger ultrasonic power, which has little disturbance to the lens 102 and has good cleaning effect.

[0039] Embodiment 2

[0040] The cleaning channels 201 are circumferentially arranged. The inlet plug 2 is provided with a cleaning liquid distribution chamber 202. The upstream ends of the cleaning channels 201 are communicated with the cleaning liquid distribution chamber 202. The chamber wall of the cleaning liquid distribution chamber 202 is provided with a channel 203. The channel 203 penetrates to the outside of the inlet plug 2 and is connected with the cleaning pump 4 through a pipeline 501. The cleaning channels 201 are outwardly inclined from the end far away from the instrument channel 101 to the end close to the instrument channel 101, and the cleaning channels 201 are not parallel to the axis of the inlet plug 2.

[0041] Specifically, in the embodiment, the cleaning channels 201 are outwardly inclined and circumferentially arranged, so that the sprayed single-path cleaning liquid obliquely contacts the inner wall of the instrument channel 101 and flows along the inner wall of the instrument channel 101 in a spiral direction. The multiple-path cleaning liquid flows downstream in a cross spiral circumferential direction. This mode can make the cleaning liquid flush the inner wall of the instrument channel 101 as much as possible and obliquely flush the adhered dirt, thereby improving the cleaning effect.

[0042] The cleaning liquid distribution chamber 202 is arranged in the middle of the inlet plug 2. The upstream ends of all the cleaning channels 201 are arranged on the bottom wall of the cleaning liquid distribution chamber 202. The cleaning pump 4 draws the cleaning liquid from the cleaning liquid container 8 and pressurizes it. The pressurized cleaning liquid is sent to the channel 203 through the pipeline 501 and then enters the cleaning liquid distribution chamber 202 and is sprayed along different cleaning channels 201.

[0043] Embodiment 3

[0044] The ultrasonic transducer 4 is connected with the outlet plug 3 through a first flexible rod 6. The outlet plug 3 is provided with a discharge hole 301. The discharge hole 301 is provided with a separable plugging member 302. The plugging member 302 is connected with the first flexible rod 6 through a second flexible rod 7.

[0045] Specifically, the first flexible rod 6 is, for example, an elastic plastic rod. The main function of the first flexible rod 6 is to connect the outlet plug 3 and avoid the loss of the outlet plug 3. Secondly, the connection of the first flexible rod 6 with the ultrasonic transducer 4 can also transmit the ultrasonic energy to the outlet plug 3 through the first flexible rod 6, and then to the cleaning liquid in the instrument channel 101 through the outlet plug 3.

[0046] The discharge hole 301 is coaxially arranged with the outlet plug 3. The plugging member 302 is plug-in connected with the discharge hole 301. The plugging member 302 can be prevented from falling off by wrapping rubber or interference outside the plugging member 302. When it is necessary to seal the instrument channel 101 for ultrasonic cleaning, the plugging member 302 is installed on the discharge hole 301. When it is not necessary to seal the instrument channel 101, such as when the cleaning liquid is replaced, the plugging member 302 is removed from the discharge hole 301. The removed plugging member 302 is hung on one side of the outlet plug 3 through the second flexible rod 7 to avoid loss.

The device also comprises a guide wire 9 and a soft brush block 901, which is connected with the guide wire 9, and the outer diameter of the soft brush block 901 is not greater than the inner diameter of the instrument channel 101.

[0049] Specifically, in the embodiment, the cleaning liquid containers 8 are, for example, ultrasonic cleaning agent containers or disinfectant containers. During cleaning, the cleaning liquid pipeline 502 of the cleaning pump 4 is connected with the ultrasonic cleaning agent container, and the instrument channel 101 is cleaned with the special ultrasonic cleaning agent. When the ultrasonic cleaning is completed, the guide wire 9 is inserted into the instrument channel 101 and is pulled to brush the inner wall of the instrument channel 101 with the soft brush block 901, so as to remove the residual dirt (the dirt is peeled off after the ultrasonic action, so compared with the cleaning method of direct brushing or scraping, the soft brush block 901 is softer and causes less damage to the instrument channel 101). Then, the cleaning liquid pipeline 502 of the cleaning pump 4 is connected with the disinfectant container, the inner wall of the instrument channel 101 is disinfected with the disinfectant, and then the instrument channel 101 is dried by using a drying machine (not shown).

[0050] The use mode and principle of the device are as follows:

[0051] In the ordinary cleaning mode, only the inlet plug 2 needs to be inserted, and the cleaning liquid is sprayed from the cleaning channel 201 on the end surface of the inlet plug 2 to wash the inner wall of the instrument channel 101 of the endoscope 1 and then flows out from the outlet of the instrument channel 101 of the endoscope 1, so as to flush the instrument channel 101.

[0052] In the high-efficiency cleaning mode, the inlet plug 2 is inserted and the cleaning liquid is injected, the outlet plug 3 is sealed to the outlet end of the instrument channel 101, so that the instrument channel 101 is filled with the cleaning liquid and remains sealed, then the ultrasonic transducer 4 is turned on, the ultrasonic energy is transmitted to the cleaning liquid in the instrument channel 101 along the inlet plug 2, the cleaning liquid can transmit the ultrasonic energy to peel off the adhered dirt on the inner wall of the instrument channel 101, after a period of time, the outlet plug 3 is opened to discharge the cleaning liquid and the dirt. When the ultrasonic cleaning is completed, the guide wire 9 is inserted into the instrument channel 101 and is pulled to brush the inner wall of the instrument channel 101 with the soft brush block 901, so as to remove the residual dirt (the dirt is peeled off after the ultrasonic action, so compared with the cleaning method of direct brushing or scraping, the soft brush block 901 is softer and causes less damage to the instrument channel 101). Then, the cleaning liquid pipeline 502 of the cleaning pump 4 is connected with the disinfectant container, the inner wall of the instrument channel 101 is disinfected with the disinfectant, and then the instrument channel 101 is dried by using a drying machine (not shown).

[0053] The lens 102 and the outer wall of the endoscope 1 are externally cleaned, and the cleaning methods are various, convenient, and can directly use manual wiping or chemical cleaning agent soaking, or use the inlet plug 2 to spray cleaning liquid to clean the lens 102 and the outer wall.
