Technical Field

The application relates to the field of medical instruments, in particular to a split type electric balloon pressure filling device.

Background

Interventional radiology, also called interventional therapeutics, is an emerging discipline combining image diagnosis and clinical treatment, which has been rapidly developed in recent years. Under the guidance and monitoring of digital subtraction angiography, CT, ultrasound, magnetic resonance and other imaging devices, puncture needles, catheters and other interventional devices are used to introduce specific instruments into the pathological changes of human body through natural ducts or tiny wounds for minimally invasive treatment.

For example: percutaneous Transluminal Coronary Angioplasty (PTCA) is the most basic and leading interventional technique for treating atherosclerotic coronary stenosis. The main operation mode is that the saccule dilating catheter is inserted into the stenosis part of coronary artery by percutaneous puncture method, and the saccule is dilated and expanded under the guidance and monitoring of medical imaging equipment to dilate the stenosis part of coronary artery or graft stenosis part, increase the blood flow of cardiac muscle and improve the perfusion of cardiac muscle, which is a basic coronary heart disease treatment technology.

Referring to fig. 1, a balloon dilation catheter 1 includes a catheter 11 and a balloon 12 fixed to one end of the catheter 11. At present, when the balloon 12 is expanded, a balloon pressurizer is mainly adopted to provide expansion force for the balloon 12, the existing balloon pressurizer is similar to an injector and mainly comprises an inflator 3 and a piston rod 4 connected in the inflator 3 in a sliding manner, and one end of the piston rod 4 extends out of the inflator 3 for people to operate.

When the inflatable balloon is used, a worker directly operates the piston rod 4 to slide in the inflator 3, so that gas in the inflator 3 can be conveyed into the balloon 12 through the connecting pipe 31 and the catheter 11, or the gas in the balloon 12 is sucked into the inflator 3, and the expansion of the balloon 12 is realized.

At present, when the balloon is expanded, a worker needs to hold the inflator pump with one hand and operate the piston rod with the other hand, so that the operation is very troublesome; and because the piston rod slides in the inflator pump to convey the gas to the saccule, the extrusion force at the coronary artery stenosis part needs to be overcome, so the manual operation of the piston rod is very laborious, and the labor intensity is high. The field people also consider changing the pressurizer into the electric pressurizer, but the structure of the pressurizer is increased to complicate the structure of the pressurizer, so that the manufactured electric pressurizer has higher overall cost, the balloon pressurizer is a disposable consumable product, and the higher cost also causes people to give up the research of the electric pressurizer, so that the currently used balloon pressurizer still slides in the inflator by manually operating the piston rod. The problem of how to reduce the complexity of the worker for driving the piston rod to reciprocate on the basis of not increasing excessive cost is always a difficult problem in the field of research.

The length direction of the unlocking rod 71 is perpendicular to the length direction of the mounting shell 2, the cross section of the pressing cap 72 is U-shaped, and the unlocking rod 71 is fixedly connected to the U-shaped groove bottom of the pressing cap 72. Under the normal state, a force which slides towards the outside of the mounting shell 2 is given to the unlocking rod 71 through the pressing cap 72 under the action of the elastic force of the return spring 73 until the limiting ring 74 abuts against the inner wall of the mounting shell 2, so that the sliding limit position of the unlocking rod 71 is limited, and at the moment, a gap is reserved between the unlocking rod 71 and the clamping plate 61, and the unlocking rod 71 and the clamping plate are not contacted with each other.

When the balloon 12 is inflated and expanded to complete and the piston rod 4 needs to be taken down from the sliding block 51, the worker directly presses the pressing cap 72 externally, at this time, the pressing cap 72 drives the unlocking rod 71 to slide towards the inside of the installation shell 2 and extrude the return spring 73 until the unlocking rod 71 is located at one end inside the installation shell 2 and abuts against the clamping plate 61, along with the continuous sliding of the unlocking rod 71, the unlocking rod 71 also drives the clamping plate 61 to rotate so as to extrude the abutting spring 642, at this time, the clamping plate 61 also drives the two hooks 62 to be away from each other, so that the opening of the placing space 63 is enlarged, and the worker directly takes out the fixing plate 43 from the placing space 63.

Referring to fig. 5, a protection cylinder 75 is further fixedly connected to the outer surface of the mounting housing 2, the protection cylinder 75 is sleeved on the unlocking rod 71, and the pressing cap 72 is located inside the protection cylinder 75, so that the protection cylinder 75 can seal the portion between the pressing cap 72 and the mounting housing 2, and the influence of external impurities on the service life of the return spring 73 due to the fact that the external impurities reach the position of the return spring 73 from between the pressing cap 72 and the mounting housing 2 is avoided.

Meanwhile, in order to avoid the influence of the part of the unlocking rod 71 penetrating through the installation shell 2 on the overall strength of the installation shell 2, so that the installation shell 2 is stressed and damaged, a reinforcing cylinder 76 is fixedly connected to the outer wall of the installation shell 2, and the reinforcing cylinder 76 is sleeved on the unlocking rod 71 to increase the support of the installation shell 2 and protect the installation shell 2. And a sliding space in which the pressing cap 72 is fitted is formed between the outer wall of the reinforcing cylinder 76 and the inner wall of the protective cylinder 75, and when the pressing cap 72 is pressed, the pressing cap 72 slides in the sliding space.

Referring to fig. 5, in order to limit the rotation angle of the clamping plate 61, a guide groove 611 is formed in the clamping plate 61, a guide rod 612 is fixed to a side wall of the mounting groove 511, the guide rod 612 is slidably disposed in the guide groove 611, and the guide groove 611 has an arc shape and a center of circle thereof coincides with the hinge axis of the clamping plate 61. When the holding plate 61 rotates, the position of the guide rod 612 in the guide groove 611 is also changed, thereby limiting the extreme rotational position of the holding plate 61.

The implementation principle of the split type electric balloon pressure filling device in the embodiment of the application is as follows: in use, the end of the catheter 11 away from the balloon 12 is directly mounted on the connecting tube 31, and the connection between the catheter 11 and the connecting tube 31 is conventional and will not be described in detail. Then, the inflator 3 is operated to insert the snap ring 32 into the insertion slot 21, and the fixing plate 43 slides into the placing space 63 along the inclined surface of the hook 62; then, the inflator 3 is rotated, so that the snap ring 32 is rotated into the fixing groove 22, thereby fixing the positions of the inflator 3 and the mounting case 2, and the piston rod 4 and the slide block 51. The operator directly holds the handle 8, presses the switch button 811, and then presses the forward button 812, so that the piston rod 4 can be driven to move in one direction; and the retreating button 813 is pressed to drive the piston rod 4 to move towards the other direction, so that the balloon 12 is automatically inflated and expanded. After the use, the worker directly presses down the pressing cap 72 with one hand and operates the inflator pump 3 with the other hand to rotate, so that the snap ring 32 rotates into the slot 21 and is positioned corresponding to the slot 21, and the inflator pump 3 and the piston rod 4 can be directly driven to move towards the direction far away from the installation shell 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
