Abstract
The utility model belongs to an external device for controlling annular constriction of pulmonary artery banding, which aims to solves the problems in the background art that firstly, if vital signs of a postoperative patient are abnormal, when the tightness degree of the pulmonary artery banding is required to be adjusted again, an emergency operation is required to be performed; secondly, during operation, the tightness degree of the pulmonary artery banding is adjusted as per each vital sign, time is spent in observation and waiting, which cause too long operation time (generally, about more than 4 hours); and thirdly, during operation, the pulmonary artery banding is required to be dismantled and sewn repeatedly, which causes large wound. The technical proposal has the key points that a motor is arranged on a fixed bracket, two ends of each flexible gear rack penetrate through two strip-shaped holes formed on the fixed bracket to encircle the pulmonary artery, the gears connected with the output shaft of the motor are meshed with the flexible gear racks, and the motor is connected with an external power supply. The external device for controlling annular constriction of pulmonary artery banding is applied to annular constriction operation of the pulmonary artery banding, and has the outstanding advantages of convenience in control; a secondary operation is eliminated and the like.
Description
Technical field: this utility model belongs to the operation device of medical field, the device that particularly a kind of external control pulmonary artery banding ring contracts.
The ring of background technology: carrying out the first phase operation of complicated congenital heart disease staging operation---pulmonary artery banding is drawn back one's hand in the art, often need be according to indexs such as the aortic blood pressure of patient in the art, pulmonary artery blood pressure, blood oxygen saturations, regulate the tensity of pulmonary artery banding repeatedly, in the hope of reaching comparatively ideal effect.The existing problem of this mode: the one, unusual if vital signs appear in operation back patient, in the time of need regulating the pulmonary artery banding degree of tightness once more, need emergency operation; The 2nd, adjust the band degree of tightness according to every life index in the operation, need to observe the time of waiting for, cause operating time long, often need more than 4 hours; The 3rd, in the operation pulmonary artery banding is removed repeatedly, sewed up, cause wound big.
Summary of the invention: the purpose of this utility model is exactly the technical scheme that proposes the device that a kind of external control pulmonary artery banding ring contracts, exist with the solution background technology: the one, unusual if vital signs appear in operation back patient, in the time that the pulmonary artery banding degree of tightness need being regulated once more, need emergency operation; The 2nd, adjust the band degree of tightness according to every life index in the operation, need to observe the time of waiting for, cause operating time long, often need more than 4 hours; The 3rd, in the operation pulmonary artery banding is removed repeatedly, sewed up, cause wound big.Solving this technical problem the technical scheme that is adopted is: the device that a kind of external control pulmonary artery banding ring contracts, it is characterized in that being provided with on the fixed mount motor, the two ends of flexible rack pass two set cylindrical voids of fixed mount form can to Pulmonic around, the gear that output shaft connected and the flexible rack of motor are meshing with each other, motor connector external power.Wherein, be provided with on the fixed mount and can sew up the stitching connecting hole that is connected with pulmonary artery.
The beneficial effect that this utility model is had compared with the prior art is: owing to adopt technique scheme, this device can be sewed up in the operation be connected on the pulmonary artery and formation to Pulmonic around.Like this, the one, vital signs to occur unusual if operation finishes the back patient, in the time of need regulating the pulmonary artery banding degree of tightness once more, just changes or reverse by operating power control motor external, the arteries and veins band is loosened or strains, and do not need emergency operation.The 2nd, the time that does not need to observe wait in the operation, significantly shorten operating time.The 3rd, need not remove repeatedly, sew up pulmonary artery banding in the operation, avoid causing wound.
Description of drawings: Fig. 1 is the overall structure sketch map of user mode of the present utility model.
The specific embodiment: with reference to figure 1, the device that a kind of external control pulmonary artery banding ring contracts, it is characterized in that being provided with on the fixed mount 4 motor 2, the two ends of flexible rack 3 pass two set cylindrical voids of fixed mount 4 form can to pulmonary artery 5 around, the gear that output shaft connected and the flexible rack 3 of motor 2 are meshing with each other, motor 2 connector external powers 1 are provided with on the fixed mount 4 and can sew up the stitching connecting hole 6 that is connected with pulmonary artery.
