Positioning puncture device for cardiology department surgery

Abstract

The invention relates to the technical field of medical instruments, and discloses a positioning puncture device for cardiology department surgery. The positioning puncture device comprises two groups of fixing blocks and sleeving ring blocks which sleeve the fixing blocks and can slide up and down, and the sleeving ring blocks are rectangular blocks with hollow interiors. When the integral device performs a surgery on a patient, connecting bottom plates at the bottoms of the two groups of fixing blocks can be fixedly connected with an external bed body mechanism in a threaded mode through fixing screw rods and second external threads, so that a puncture needle at the bottom of a puncture rod can be adjusted and shaken through a movable adjusting ball, and the bottom of the puncture needle is aligned to the surgical position of the patient; and the angles of the puncture rod and the puncture needle on the movable adjusting ball are fixed and limited, the puncture rod has certain stability, the puncture rod is extruded in the movable adjusting ball to drive the puncture needle to perform a surgery on the patient, so that the stability of the puncture rod and the puncture needle is ensured, and the operation risk of the patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning puncture device for cardiology operations. Background technique [0002] Pericardiocentesis is a diagnosis and treatment technique that directly penetrates the pericardial cavity with the help of a puncture needle. Pericardial puncture must be performed under aseptic technique, local application of procaine anesthesia, the puncture site should not be too deep, so as not to puncture the atrium, ventricle or puncture the coronary artery and cause a large amount of hemorrhage in the pericardial cavity. [0003] In the existing process of performing pericardial puncture on patients, the traditional method is that the operator performs hand-held puncture to puncture the patient's pericardium. When the puncture takes a long time, the labor intensity of the operator will be increased, resulting in poor stability of the puncture needle itself. However, when the...

[0003] In the existing process of performing pericardial puncture on patients, the traditional method is that the operator performs hand-held puncture to puncture the patient's pericardium. When the puncture takes a long time, the labor intensity of the operator will be increased, resulting in poor stability of the puncture needle itself. However, when the surgeon holds the needle for a long time, the risk of cardiology surgery will increase, which will increase the risk of the patient itself. Therefore, we propose a positioning puncture device for cardiology surgery
