Description

Technical Field

[0001] The utility model relates to the technical field of flushing, in particular to a flushing device. Background Art

[0002] Arthroscopic surgery involves inserting a metal tube with a lens and a lighting device into the joint cavity through a very small incision. The internal structure of the joint cavity is magnified on the monitor to observe the condition and location of the lesions in the joint cavity. At the same time, a comprehensive inspection and cleaning of the diseased area is performed. In the process of cleaning the diseased area, in addition to scraping and picking with various knives, an irrigator and related liquid medicines are used to flush and clean the wound surface, keep the surgical field clear, and promote rapid recovery after surgery.

[0003] When using existing flushing equipment, medical staff usually need to hold the flusher and insert it through the incision to flush the inside of the joint cavity. However, when the staff flush the lesions at different depths in the patient's joint cavity, they cannot have a good control over the subtle depth of insertion and cannot locate the detailed adjustment depth. Utility Model Content

[0004] The utility model aims to provide a flushing device to solve the shortcomings in the prior art that when workers flush lesions at different depths in the patient's joint cavity, they cannot well control the subtle insertion depth and cannot perform detailed positioning of the adjusted depth.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flushing device comprises a flusher, wherein the outer wall of the flusher is slidably connected to a sleeve, the outer wall of the sleeve is fixedly connected to a shell, a first slider is fixedly connected to one side of the flusher, the first slider slides through the sleeve and extends to the inside of the shell, two pressure plates are fixedly connected to the top of the first slider, an inner wall of one side of the shell is fixedly connected to an L-shaped plate, the L-shaped plate is located above the first slider, and a downward moving component for driving the first slider to move downward is arranged between the inner walls on both sides of the shell;

[0007] The downward moving assembly includes a plurality of U-shaped pads slidably connected to the inner wall of the shell, a pressing block slidably penetrates the inner wall of one side of the shell, and a first connecting rod is fixedly connected to one side of the pressing block;

[0008] The pressing block has a fixing assembly inside for fixing the U-shaped pad after it has moved downward.

[0009] In one possible design, the fixing component includes a groove opened on the inside of the pressing block, a second slider is slidably connected between the inner walls on both sides of the groove, a second spring is fixedly connected between the bottom of the second slider and the bottom inner wall of the groove, a second connecting rod is fixedly connected to one side of the second slider, the second connecting rod slides through the pressing block and extends to one side of the pressing block, and a first spring is fixedly connected to the side of the pressing block close to the L-shaped plate.

[0010] In a possible design, the top of the first sliding block and the bottom of the L-shaped plate are fixedly connected with a same tension spring.

[0011] In a possible design, the multiple U-shaped pads include a first connecting plate, a second connecting plate, and a third connecting plate. The second connecting plate and the third connecting plate are respectively fixedly connected to both sides of the first connecting plate, and the multiple third connecting plates are each provided with a through groove inside.

[0012] In a possible design, one side of the second connecting plate is arranged in an arc shape, and the second connecting plate is used in conjunction with the first connecting rod.

[0013] In a possible design, one side of the third connecting plate is arc-shaped, and the third connecting plate is used in conjunction with the second connecting rod.

[0014] In the present application, when in use, the staff inserts a sleeve filled with physiological saline or other liquid into the patient's joint cavity through the incision, and cleans and flushes the patient's diseased area with the cooperation of the arthroscope. During the flushing process, when it is necessary to adjust the depth position of the sleeve in the patient's joint cavity, the staff can press the pressing block, and the pressing block will squeeze the first spring during the pressing process. The movement of the pressing block drives the first connecting rod and the second connecting rod to move synchronously. During the movement, the first connecting rod will contact the arc surface of the second connecting plate and push the second connecting plate downward. The second connecting plate moves downward and synchronously drives the pressing plate, the first slider, and the flusher to move downward to adjust the downward depth of the flusher. At the same time, during the movement of the second connecting rod, since the first connecting rod pushes the second connecting plate downward when moving, the second connecting plate drives the third connecting plate to move downward synchronously, and the third connecting plate will synchronously drive the second connecting rod to move downward. During the downward movement of the second connecting rod, the second slider moves and squeezes the second spring. As the pressing block moves, when the second connecting rod moves to the position of the through groove, the second spring The pressing block is then released, and under the action of the first spring, the pressing block rebounds, synchronously driving the first connecting rod and the second connecting rod back to their original positions. In the process of returning to their original positions, the second connecting rod contacts the arc surface of the third connecting plate and pushes the third connecting plate downward. The third connecting plate moves downward and synchronously drives the pressure plate, the first slider and the flusher to move downward, and the downward depth of the flusher is adjusted. When the pressing block returns to its original position, the second connecting rod stops at the top of the third connecting plate, and the U-shaped pad that has been adjusted is pressed. The U-shaped pad is limited and fixed, and under the action of gravity, the upper U-shaped pad will fall naturally. The staff can press the pressing block multiple times according to the required depth of downward adjustment. Each time it is pressed and released, a U-shaped pad can be automatically moved down to locate the depth of movement of the adjustment sleeve. When the flushing is completed, the sleeve is pulled out, and the pressing block is pulled so that the second connecting rod no longer limits and fixes the third connecting plate. Under the action of the tension spring, a tensile force rebound is generated, which can synchronously drive multiple U-shaped pads to move up, so that the flusher returns to its initial position and waits for the next use.

[0015] In the utility model, the flushing device can drive the first connecting rod and the second connecting rod to move the U-shaped pad downward once by pressing and releasing the pressing block once, so as to adjust the depth of the flusher once, control the descending depth of the flusher, and limit and fix the U-shaped pad after it moves downward, which is simple, fast and convenient.

[0016] In the utility model, the flushing device can be operated by pulling the pressing block after use, so that the multiple U-shaped pads can be moved upward again under the action of the tension spring, so that the multiple U-shaped pads can return to their original positions, which is convenient for the next operation;

[0017] In the utility model, by pressing and then releasing the pressing block, a U-shaped pad can be pushed downward, so that the flusher can be lowered once, and the depth of descent can be controlled. The staff can press the pressing block multiple times according to the depth that the flusher needs to be lowered. When the flushing is completed, the pressing block can be pulled to restore all the U-shaped pads to their original positions, waiting for the next operation. BRIEF DESCRIPTION OF THE DRAWINGS
