Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a lower limb deep vein thrombosis aspiration device with an anti-blocking function. Background Technique

[0002] A thrombus is a small mass formed on the surface of a peeling or repaired area on the inner surface of blood vessels in the cardiovascular system. In a variable fluid-dependent type, a thrombus is composed of insoluble fibrin, deposited platelets, accumulated white blood cells, and trapped red blood cells. Vascular treatment mainly includes drug treatment and artificial mechanical methods, among which thrombus aspiration is an interventional treatment method that sucks out thrombus through a suction catheter using the principle of negative pressure suction. This treatment method is mainly applicable to the situation where there is a large amount of thrombus in the blood vessels.

[0003] The existing method and device are not flexible enough to use, and the angle of the suction pipe head cannot be adjusted flexibly. Therefore, the utility model proposes a lower limb deep vein thrombosis aspiration device again. Content of the Utility Model

[0006] The purpose of the utility model is achieved through the following technical solutions: A lower limb deep vein thrombosis aspiration device with an anti-blocking function, including a handle and a sleeve rod fixedly installed with the handle. An inner core pipe is rotatably connected inside the sleeve rod. One end of the inner core pipe close to the handle is fixedly provided with a turning knob, and the other end of the inner core pipe away from the turning knob is provided with a suction pipe head.

[0007] Scale lines are provided on the outer surface of the turning knob, and a pointer is fixedly provided on one side of the handle close to the turning knob.

[0008] Preferably, a separating blade is arranged inside the suction pipe head. The separating blade is fixed in the lumen of the suction pipe head, and the separating blade is distributed in a cross-star shape.

[0009] Preferably, a rotating hole is opened at the position of the handle corresponding to the inner core pipe, and the inner core pipe is connected with the rotating hole through a bearing.

[0010] Preferably, an insulating layer is provided on the outer surface of the sleeve rod.

[0011] Preferably, the number of the scale lines is several, and several scale lines are evenly distributed in a circumferential shape on the outer surface of the turning knob.

[0012] Preferably, the outer surface of the handle is provided with an anti-slip layer.

[0013] Preferably, one end of the handle close to the rotary knob is fixedly provided with an interface pipe, the interface pipe is communicated with the inner core pipe, and the interface pipe is connected to the extraction pump through a hose.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] For the lower limb deep vein thrombosis aspiration device with anti-blocking function, by setting the rotary knob, scale line and pointer, when the rotary knob rotates, the inner core pipe will drive the suction tube head to rotate synchronously, and then medical staff can quickly judge the rotation angle of the suction tube head according to the positional relationship between the scale line and the pointer, achieving the effect of convenient operation. By setting the separation blade in the suction tube head, under the power output of the extraction pump, large blood clots can be separated into small fragments by the separation blade, thereby avoiding the phenomenon of blockage in the pipeline.

[0026] Such as Figures 1-5As shown in the figure, a lower limb deep vein thrombosis aspiration device with an anti-blocking function includes a handle 1 and a sleeve rod 2 fixedly installed on the handle 1. An anti-slip layer 103 is provided on the outer surface of the handle 1. By using the anti-slip layer 103, the friction with the front surface of the medical staff's hand can be increased, so as to facilitate the medical staff to control the movement of the handle 1. An insulating layer 201 is provided on the outer surface of the sleeve rod 2. By using the insulating layer 201, an inner core pipe 3 is rotatably connected inside the sleeve rod 2. A rotation hole 104 is opened at the position of the handle 1 corresponding to the inner core pipe 3. The inner core pipe 3 is connected to the rotation hole 104 through a bearing 105. By using the bearing 105, the inner core pipe 3 can be easily combined with the handle 1, so that the friction during the rotation of the inner core pipe 3 can be reduced during use, and the stability and accuracy during the rotation of the inner core pipe 3 can be improved. A rotating knob 4 is fixedly provided at one end of the inner core pipe 3 close to the handle 1. A suction pipe head 5 is installed at one end of the inner core pipe 3 far from the rotating knob 4. An interface pipe 102 is fixedly provided at one end of the handle 1 close to the rotating knob 4. The interface pipe 102 is communicated with the inner core pipe 3. The interface pipe 102 is connected to a suction pump 7 through a hose 6. A separation blade 501 is arranged inside the suction pipe head 5. The separation blade 501 is fixed in the lumen of the suction pipe head 5, and the separation blade 501 is distributed in a cross-star shape.

[0027] Scale lines 401 are provided on the outer surface of the rotating knob 4. The number of the scale lines 401 is several. The several scale lines 401 are evenly distributed in a circumferential manner on the outer surface of the rotating knob 4. A pointer 101 is fixedly provided on one side of the handle 1 close to the rotating knob 4. When the rotating knob 4 rotates, the inner core pipe 3 will drive the suction pipe head 5 to rotate synchronously. Then, the medical staff can quickly judge the rotation angle of the suction pipe head 5 according to the positional relationship between the scale lines 401 and the pointer 101.
