CN102166126A - Device for controlling pulmonary artery strap cyclic condensation in vitro - Google Patents

Abstract

The invention belongs to a device for controlling pulmonary artery strap cyclic condensation in vitro. The problems to be solved in the prior art are as follows: if the vital signs of a patient are abnormal after a surgery, the patient needs an emergency surgery when the tightness of the pulmonary artery strap needs to be regulated again; time for observation and waiting is required when the tightness of the pulmonary artery strap is adjusted according to each vital sign, which cause too long surgery time, generally more than four hours; and the pulmonary artery strap needs to be repeatedly removed and sutured during the surgery, which cause a big trauma. The device has the technical scheme key points that a mounting bracket is provided with a motor; two ends of a flexible rack penetrate through two strip-shaped holes arranged on the mounting bracket to surround the pulmonary artery; a gear connected with the output shaft of the motor is mutually meshed with the flexible rack; and the motor is connected with an in-vitro power supply. The device can be applied to the pulmonary artery strap cyclic condensation surgery, is convenient to control and can avoid secondary surgery.

Description

The device that a kind of external control pulmonary artery banding ring contracts

Technical field: the invention belongs to the operation device of medical field, the device that particularly a kind of external control pulmonary artery banding ring contracts.

Background technology: perform the operation in the first phase of carrying out the complicated congenital heart disease staging operation---the pulmonary artery banding ring 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: purpose of the present invention 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 the present invention 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 invention.

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 fixedmount 4motor 2, the two ends offlexible rack 3 pass two set cylindrical voids of fixedmount 4 form can topulmonary artery 5 around, the gear that output shaft connected and theflexible rack 3 ofmotor 2 are meshing with each other,motor 2 connectorexternal powers 1 are provided with on thefixed mount 4 and can sew up thestitching connecting hole 6 that is connected with pulmonary artery.

Claims (2)
