Abstract

The invention discloses a quick-changing connector for the connection of a deep vein thrombosis removing machine and a power device. The quick-changing connector for the connection of the deep vein thrombosis removing machine and the power device comprises a connector body. The connector body comprises an axially-through central tube and a mantle. The tail portion of the connector body is provided with a tail latch mechanism used for being connected with the power device, the front portion of the connector body is provided with a front latch mechanism used for being connected with the deep vein thrombosis removing machine, and the tail latch mechanism is connected with a spanner switching mechanism used for separating the tail latch mechanism from the power device quickly. According to the quick-changing connector, quick connection and separation of the designed deep vein thrombosis removing machine and the power device can be achieved, the installation operation is fast and convenient, the axial positioning and lateral positioning are reliable, and the whole surgery process is safe and stable.

Description

technical field [0001] The invention relates to a connecting piece, in particular to a quick-change connecting head for connecting a deep vein thrombus remover with a power device. Background technique [0002] In recent years, due to changes in dietary structure and other reasons, the incidence of deep venous thrombosis in people's lower extremities has shown an increasing trend year by year. Long-term accumulation of venous thrombus will cause blood flow obstruction and stasis, resulting in long-term swelling of the lower limbs, varicose veins, and thus the formation of thrombophlebitis in the veins. In more serious cases, venous thrombus dislodges and transfers to organs may lead to fatal complications, for example, venous thrombus transfers to the lungs and accumulates, which can cause embolism death of the patient. The treatment method of thrombus has: 1, internal medicine treatment, mainly adopt anticoagulant, thrombolysis and other drug treatments. Bleeding or hemor...
