Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular, to a medical irrigator. Background Art

[0002] During endoscopic surgery, there will be blood or foreign objects blocking in the sheath cavity, affecting the observation field of view area. A medical irrigator is needed. There are two types on the market. One is a reusable medical endoscope irrigator with a larger housing, and the other is a gun-type, disposable product.

[0003] Clinically reusable medical endoscope irrigators are composed of a main unit (including a power supply part, a control part, a display part, a motor, and a pump body) and pipelines. It needs to be connected to the mains power for use. The chassis is large and the operation is not convenient. Although it can be reused, it needs to be cleaned and disinfected after each use, and there is a risk of cross-infection among patients, so the surgery cannot be performed continuously.

[0004] Most disposable medical irrigators are gun-type and work on the pulse principle. They are not dedicated to endoscopes. When flushing, they cannot be adapted to the sheath, resulting in incomplete flushing and unable to form an optimal visible space. The flushing force is not enough to thoroughly clean the blood stains in the cavity, making the field of view during the examination and surgery not clear enough, affecting the time and effect of the examination and surgery, and unable to meet the ideal surgical effect. Summary of the Utility Model

[0005] In order to effectively solve the problems of inconvenient operation of existing medical irrigators, the risk of cross-infection among patients during repeated use, and the inability to perform consecutive surgeries, etc., the present application provides a medical irrigator.

[0006] The medical irrigator provided by the present application adopts the following technical solutions:

[0010] The flushing pipeline is arranged outside the housing and includes a flushing tube, a liquid inlet tube and a connector. The flushing tube includes a first flushing tube and a second flushing tube. One end of the first flushing tube is connected to the sheath of the arthroscope, and the other end is connected to the water pipe hole.

[0022] Preferably, the control valve is a one-way valve.

[0023] By adopting the above technical solution, the control valve is set as a one-way valve to prevent the mixed pollution of the liquid after flushing to the liquid before flushing when the liquid is reciprocally circulated through the control module.

[0024] Preferably, the energy supply member is a multi-section battery installed on the base. The battery matrix is arranged in the base and is controlled by a power switch provided at the bracket.

[0026] Preferably, the motor is disposed between the PCB board and the power switch.

[0027] By adopting the above technical solution, the motor is disposed between the PCB board and the power switch. During use, the power switch supplies power from the battery to the motor.

[0029] 1. When performing endoscopic surgery, the trocar is inserted into the solution, and the control module drives the rubber cup to circulate and reciprocate through the motor, thereby forming suction and discharge actions in the cavity formed by the rubber cup. The solution flows through the water pipe hole opened in the rubber cup to the second flushing tube through the liquid inlet pipe, and the liquid flows through another water pipe hole in the rubber cup to the first flushing tube until the arthroscope position, realizing the flushing of blood or foreign objects in the sheath cavity. Then, the flushing liquid flows out through the reverse path, effectively solving the problems of inconvenient operation of existing medical flushing devices, the risk of cross-infection among patients during repeated use, and the inability to connect consecutive surgeries;

[0030] 2. The flushing device flushes the blood or foreign objects in the sheath cavity through the circulating and reciprocating flushing pipeline. The flushing liquid will return to the liquid inlet pipe along the original path. During continuous flushing, it may cause solution contamination, resulting in a reduction in the flushing effect. The liquid inlet pipe is set to two. When flushing the sheath cavity by pumping out the solution, one liquid inlet pipe is used. At this time, the other liquid inlet pipe is branched through a stop clamp. When the dirty solution returns, the liquid inlet pipe inserted into the solution is directly flowed through the stop clamp, and the stop clamp of the liquid inlet pipe not inserted into the solution is opened, and the liquid flows out from this liquid inlet pipe, preventing solution contamination during continuous flushing and improving the flushing effect;

[0031] 3. The opening and closing of the one-way valve are adjusted through the speed control knob set on the PCB board to inhale and discharge gas and liquid, and to realize the speed regulation of the water flow rate, which is convenient for flushing the blood or foreign objects in the sheath cavity and improving the flushing effect.
