Problems solved by technology

[0003] The intravascular ultrasound imaging system is mainly composed of an intravascular ultrasound catheter with an ultrasonic sensor, a catheter driving system, and an ultrasound imaging host. The catheter driving system is mainly composed of a catheter rotation mechanism, a retraction mechanism, a base mechanism, and a housing. The clutch mechanism in the intravascular ultrasonic retraction mechanism is mainly realized by cam control, but the installation of the cam control method is more complicated, the assembly gap is large, and the operation is not stable

Abstract

The invention discloses an intravascular ultrasound retractable mechanism. The retractable mechanism includes a retractable support, and a clutch shaft and a retractable shaft which are rotatably connected to the retractable support; one end of the clutch shaft is connected to a driving system, and the other end of the clutch shaft is provided with a first semi-clutch; one end of the retractable shaft is provided with a second semi-clutch used for matching the first semi-clutch, and the other end of the retractable shaft is provided with a movable device capable of moving; and the driving system is arranged on the retractable support. When the automatic retracement of an intravascular ultrasound catheter is performed, the first semi-clutch and the second semi-clutch are in a combined state, the driving system can be started and transmits power to the clutch shaft, the clutch shaft can transmit the power to the retractable shaft, the retractable shaft can rotate, so that the movable device can be driven to move, and therefore, the automatic retracement of the intravascular ultrasound catheter can be realized; the retractable mechanism adopts a synchronous belt to perform power transmission, so that the assembling gap between parts can be reduced; and the retractable mechanism is simple in structure and can realize stable operation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an intravascular ultrasonic retraction mechanism. Background technique [0002] Intravascular ultrasound is a combination of noninvasive ultrasound technology and invasive catheter technology, a medical imaging technique that uses a special catheter with an ultrasound probe attached to the end. This technology allows ultrasound technologies, such as piezoelectric conduction or Ultrasonic sensors are used to examine the condition of the inner walls of blood vessels. [0003] The intravascular ultrasound imaging system is mainly composed of an intravascular ultrasound catheter with an ultrasonic sensor, a catheter driving system, and an ultrasound imaging host. The catheter driving system is mainly composed of a catheter rotation mechanism, a retraction mechanism, a base mechanism, and a housing. The clutch mechanism in the intravascular ultrasonic retraction mechanism i...
