[0002] With the continuous development of technology, medical standards have also improved. Especially in surgical procedures, more advanced instruments can be used to achieve better results. However, foreign objects such as tissue debris, bone fragments, and fat particles generated during surgery can cause postoperative pericardial adhesions or pleural granulomas. Using irrigation fluid can remove blood clots and prevent them from becoming a culture medium for bacterial growth.

[0003] Currently, in cardiothoracic surgery, different irrigation media are used depending on the location of the affected area, and two or more tools are used for irrigation. This makes it impossible to use any irrigation media, which complicates the surgical process and causes abnormalities. Utility Model Content

The control block is also placed on the control frame, and a set screw block is screwed onto the control block.

[0011] This utility model provides a surgical irrigation device for cardiothoracic surgery, which has the following beneficial effects:

[0012] In this invention, an external fixing component is installed on one side of the main frame assembly. The external fixing component is fastened and fixed with bolts, allowing for convenient hand-held operation. It can also be snapped into a designated position for easy use. An expansion assembly is installed within the location of the external fixing component on the main frame assembly. This expansion assembly has three sets of external connecting components, each capable of connecting to various media. Each set of external connecting components has a one-way plate, enabling unidirectional media conduction. The main frame assembly can then control the media. A positioning component is installed at the control point of the main frame assembly to ensure proper positioning of the control system and guarantee operation under specified environmental conditions.

[0013] In addition, the opening and closing block installed inside the main frame plate is placed at the inner tube, so that the opening and closing block can control the opening and closing of the inner tube of the main frame plate, thereby achieving the opening and closing function of the whole device. The bottom of the opening and closing block is directly slidably installed on the slide groove of the control frame. At the same time, the slide groove of the control frame is set in an inclined shape, so that when the control frame is manually pressed, the control frame can control the opening and closing block through the slide groove, thereby achieving the control function of the inner tube of the main frame assembly. The spring installed between the control frame and the main frame plate has the function of allowing the control frame to quickly reset after the time is up.

[0014] Furthermore, to facilitate the installation of the external block, a snap-fit ​​bracket is directly installed on the external block, which corresponds to the main frame assembly. This allows the external block to be snapped into the main frame assembly via the snap-fit ​​bracket. A fixing bracket is then snapped into the end of the snap-fit ​​bracket, and bolts are screwed into the fixing bracket. After the fixing bracket is snapped into the end of the snap-fit ​​bracket, tightening the bolts secures the external block to the main frame assembly. The external block is designed with an angled shape, making it easy to hold after installation on the main frame assembly. An external plate is installed at the bottom of the external block to assist in positioning. The groove structure on the external plate allows it to snap into the designated position, thus fixing the entire device in a fixed position.

[0015] In addition, the shape of the expansion block is directly aligned with the inner wall of the main frame assembly, allowing the expansion block to be better installed on the main frame assembly. In order to make the set screw block more stable in fixing the expansion block, an outer boss is set on the main frame assembly at the position of the expansion block, so that the set screw block is better fixed on the outer boss, and the outer boss increases the overall strength.

[0016] Furthermore, by directly designing the external connector as a bent shape, the angle of the external connector can be easily adjusted after it is connected to the pipeline, allowing the external pipeline to be placed in the appropriate position. The external connector is screwed onto the expansion assembly via a positioning sleeve. The hexagonal structure at the outer end of the positioning sleeve facilitates external control of the positioning sleeve. The contact platform at the external connector uses a rubber ring on its outer wall to achieve a stable seal after the external assembly is installed via the contact platform. To prevent backflow of the medium after the external connector is connected to the pipeline, an inner sleeve is installed on the inner side of the external connector. The inner wall of the outer end of the inner sleeve is hexagonal, facilitating control of the inner sleeve. Two sets of symmetrical one-way plates are hinged to the inner end of the inner sleeve, enabling the two sets of semi-circular one-way plates to achieve unidirectional conduction of the medium passing through, thus avoiding the problem of medium backflow.

[0017] In addition, to ensure that the control frame of the main frame assembly remains in the designated position after being pressed, a control block is directly installed at the bottom of the control frame. At the same time, after the set screw on the control block is turned, the set screw fixes the control block to the transmission rod. At this time, controlling the control block from the outside can fix the installation position of the control frame, so that the nozzle can always maintain the flushing function and achieve the specified usage effect.
