Problems solved by technology

Existing punctures generally use doctors’ bare hands or image-guided punctures. The former requires doctors to have a wealth of surgical experience; the latter requires doctors to keep an eye on ultrasound images while performing punctures, which can easily cause doctors’ hand-eye incoordination and cause puncture operations. fail
Moreover, the doctor's hand shaking during the puncture is also one of the main reasons for the puncture needle to accidentally penetrate the subclavian artery and cause complications such as pneumothorax, which seriously endangers the life of the patient.
In addition, during the puncture process, excessive puncture force causes pain to the patient, and the patient's lack of cooperation is also a factor that affects the success rate of puncture.

Abstract

The invention discloses an active and passive hybrid type subclavian vein puncture robot. The active and passive hybrid type subclavian vein puncture robot comprises a puncture angle adjusting moduleand a posture adjusting module. The puncture angle adjusting module of the robot has two active freedom degrees, namely a puncture angle adjusting freedom degree and a needle inserting freedom degree;an ultrasonic probe and a force sensor are arranged on the puncture angle adjusting module, so that the puncture success rate is increased through an ultrasonic image and puncture force data; the posture adjusting module adopts a passive type joint and is locked by a clutch or a brake, so that the robot can maintain the current state conveniently; and a gravity compensating spring is used for alleviating the labor intensity of a doctor when the mechanism height is adjusted.

Description

technical field [0001] The invention relates to an active-passive hybrid subclavian vein puncturing robot, which belongs to the technical field of medical devices. Background technique [0002] Subclavian vein catheterization is the insertion of a catheter into the superior vena cava through the subclavian vein to open up a fast and effective infusion pathway and improve the treatment efficiency of patients. Existing puncture generally uses a doctor's bare-hand puncture or an image-guided puncture. The former requires the doctor to have extensive surgical experience; the latter requires the doctor to keep an eye on the ultrasound image while performing the puncture, which is likely to cause the doctor's hand-eye incongruity to cause the puncture operation. fail. In addition, the shaking of the doctor's hand during the puncture process is also one of the main reasons for the puncture needle to mistakenly penetrate the subclavian artery and cause complications such as pneumot...
