Embodiment 1

[0058] A rotary atherectomy interventional therapy instrument for treating calcified coronary lesions, such as figure 1 As shown, it includes a rotational atherectomy instrument host 1, a pedal control panel 2, a nitrogen tank 3, a propeller 4, a rotational atherectomy catheter 5 and a rotational atherectomy guide wire 6; as figure 2 and image 3 As shown, the front of the main body of the rotary atherometer 1 is provided with a power switch key 101, a rotational speed display 102, a single rotation atherectomy time display 103, an accumulated time display 104, a reset button 105, a turbine pressure gauge 106, and a turbine adjustment knob 107 , a deceleration valve connector 108, a propeller fiber optic connector 109 and a propeller gas connection pipe joint 110, the back of the rotary atherometer host 1 is provided with a nitrogen interface 111, a foot switch hose interface 112 and a power cord 113;

[0059] Such as Figure 5 As shown, the pedal control panel 2 is provide...

Embodiment 2

[0066] On the basis of Example 1, as Figure 10 As shown, the outer walls of the two vertical plates 4082 are provided with screw holes 4084, and the insides of the screw holes 4084 are threaded with screw rods 4085. One end of the screw rod 4085 is fixed with a first rubber pad 4086, and the other end is fixed with a quincunx knob 4087.

[0067] In this embodiment, when the stroke control structure 408 is used, rotating the plum blossom-shaped knob 4087 will drive the screw rod 4085 and the first rubber pad 4086 to rotate forward or backward, and the first rubber pad 408 can be made to fix the position.

Embodiment 3

[0069] On the basis of Example 1, as Figure 11 and Figure 12 As shown, the outer walls of the two vertical plates 4082 are provided with square holes 4084A, and the upper edge of the square holes 4084A is fixed on the hinged seat 4085A, and the splint 4087A is fixed on the hinged seat 4085A through the hinge shaft 4086A, and the outer wall cover of the hinge shaft 4086A A torsion spring 4088A is provided, and a second rubber pad 4089A is fixed on the inner side wall of the splint 4087A.

[0070] In this embodiment, when the stroke control structure 408 needs to be moved, the splint 4087A can be pressed, and then the crossbar 4081 can be moved. When it needs to be fixed, the splint 4087A is released, and the splint 4087A will rotate downward under the action of the torsion spring 4088A. Until the second rubber pad 4089A touches the outer surface of the fuselage 401 , under the frictional force of the second rubber pad 4089A, the movement stroke control structure 408 will not m...

Abstract

The invention relates to the technical field of coronary rotational atherectomy, and particularly relates to a rotational atherectomy interventional treatment instrument for treating a coronary arterycalcification lesion. The rotational atherectomy interventional treatment instrument comprises a rotational atherectomy instrument host, a pedal control board, a nitrogen tank, a propeller, a rotational atherectomy catheter and a rotational atherectomy guide wire; a speed reduction switch is arranged on the pedal control board, and the outside of the pedal control board is communicated with a speed reduction control pipe and two ventilation hoses; a gas outlet connector is arranged at the top end of the nitrogen tank, and the gas outlet connector is communicated with a nitrogen interface by agas supply pipe; the propeller comprises a machine body, a moving handle, an optical fiber rotation speed connection cable, a saline solution input pipe and a gas connection pipe; a strip slot is formed on the upper end face of the machine body; the moving handle is mounted in a sliding mode inside the strip slot; scale lines are also formed on both front and rear sides of the strip slot; and a handle travel control structure is also mounted in a sliding mode on the machine body. According to the invention, a forward distance of a rotational atherectomy head can be limited, so as to effectively avoid a deviation generated due to artificial control on the front and rear process of the rotational atherectomy head and protect a coronary artery canal behind the calcification lesion position from being damaged.

Description

technical field [0001] The invention relates to the technical field of coronary artery rotational atherectomy, in particular to a rotational atherectomy interventional therapy instrument for treating coronary artery calcification lesions. Background technique [0002] With the aging of society, the prevalence of coronary heart disease is on the rise, and the proportion of coronary artery calcification has increased significantly. Coronary artery calcification refers to the deposition of calcium salts in coronary atherosclerotic plaques. Denaturation and necrosis are closely related to the occurrence of calcification. After denaturation of tissue and cell proteins, reactive groups and phosphate structures released by cell decomposition are exposed. Phosphate combines with calcium to form calcium phosphate and deposits locally. [0003] At present, coronary atherectomy technology is almost an indispensable technology for the successful completion of coronary artery interventio...
