Problems solved by technology

The endoscope in the prior art includes a working channel, a liquid inlet channel and a liquid outlet channel, which can perform low-flow liquid injection and discharge, but because the liquid outlet channel is relatively thin, there will be the following technical problems in practical applications: ( 1) There are large particles in the discharge fluid, which can easily cause blockage of the discharge channel, and the operation must be interrupted, and then the discharge channel is dredged, which affects the operation process; Take out some tissues, at present, these massive tissues can only be taken out with instruments through the working channel, the operation is cumbersome, and the operation time is increased; (3), it is impossible to provide a large flow of washing for the operation field, especially when the operation field encounters bleeding. The image will not be seen clearly, and even the operation cannot be performed normally

Embodiment 1

[0024] combine figure 1 As shown, the endoscope includes a liquid inlet channel 1 and a liquid outlet channel 2 .

[0025] There is a pulverizing part in the liquid outlet channel 2, which is used to crush the large particles entering the liquid outlet channel 2, so as to ensure that the liquid outlet channel 2 will not be blocked and realize continuous discharge of liquid.

[0026] In addition, large particles such as some tissues during the endoscopic operation can also be crushed by the crushing part, and then discharged from the liquid outlet channel 2, which is easy to operate and does not affect the operation time.

[0027] Preferably, the crushing part is detachably connected to the liquid outlet channel 2 .

[0028] Such as figure 2 and image 3 As shown, the crushing part includes a cutter head 7 and a driving part fixedly connected with the cutter head 7 .

[0029] The cutter head 7 is located at the liquid inlet 5 of the liquid outlet channel, such as figure 1...

Embodiment 2

[0043] combine Figure 4 As shown, the endoscope includes a liquid inlet channel 1 and a liquid outlet channel 2 .

[0044] A crushing part is provided in the liquid outlet channel 2 for crushing the large particles entering the liquid outlet channel 2, so that the liquid outlet channel 2 will not be blocked and the liquid can be continuously discharged.

[0045] The pulverizing component in Embodiment 2 can refer to the pulverizing component in Embodiment 1, and will not be described in detail here.

[0046] A No. 1 container 12 is connected to the liquid inlet 3 end of the liquid inlet channel, and a No. 2 container 13 is connected to the liquid outlet 6 end of the liquid outlet channel. A No. 1 pump 14 and a No. 2 pump 15 are arranged on the liquid inlet channel 1 and the liquid outlet channel 2 respectively.

[0047] The first container 12, the second container 13, and the first pump 14 and the second pump 15 are beneficial to increase the flow rate of the liquid in the ...

Embodiment 3

[0053] Embodiment 3 is a further preferred improvement made on the basis of Embodiment 2. For the parts not mentioned in Embodiment 3, reference can be made to Embodiment 2.

[0054] Such as Figure 5 As shown, the No. 1 container 12 is configured with a No. 1 metering sensor 18 , and the No. 2 container 13 is configured with a No. 2 metering sensor 19 . Each metering sensor can be selected from a sensor capable of measuring the weight or volume of the working fluid in the container.

[0055] The No. 1 pump 14 and the No. 2 pump 15 are equipped with a central controller 20 capable of controlling the operating states of the pumps. The No. 1 metering sensor 18 and the No. 2 metering sensor 19 are respectively connected to the central controller 20 .

[0056] In the above method, a No. 1 pressure sensor 21 can also be provided on the liquid inlet passage 1 between the No. 1 pump 14 and the liquid outlet 4 ends, and a pressure sensor 21 can be arranged on the liquid outlet betwe...

Abstract

The invention discloses an endoscope and a device with the same. The endoscope comprises a liquid feeding channel and a liquid draining channel; and a smashing component is arranged in the liquid draining channel and is used for smashing large particles entering the liquid draining channel. The technical problem that the liquid draining channel is easy to block is solved. A liquid feeding opening end of the liquid feeding channel is connected with a first container; the liquid feeding channel is provided with a first pump; a liquid draining opening end of the liquid draining channel is connected with a second container; the liquid draining channel is provided with a second pump; and the irrigation efficiency of the endoscope can be improved through the first container, the second container, the first pump and the second pump. By the endoscope, the bottleneck problem on application of the existing endoscope is solved effectively, and the surgery application range of the endoscope is expanded obviously.

Description

technical field [0001] The invention relates to an endoscope and a device with the endoscope. Background technique [0002] At present, endoscopes are widely used in the field of surgery. The endoscope in the prior art includes a working channel, a liquid inlet channel and a liquid outlet channel, which can perform low-flow liquid injection and discharge, but because the liquid outlet channel is relatively thin, there will be the following technical problems in practical applications: ( 1) There are large particles in the discharge fluid, which can easily cause blockage of the discharge channel, and the operation must be interrupted, and then the discharge channel is dredged, which affects the operation process; Take out some tissues, at present, these massive tissues can only be taken out with instruments through the working channel, the operation is cumbersome, and the operation time is increased; (3), it is impossible to provide a large flow of washing for the operation ...
