Embodiment Construction
[0118] Hereinafter, the present invention will be described with reference to the accompanying drawings.
[0119] The device consists of a housing 1 made of plastic by injection molding ( figure 1 ), where the surface of the housing (where the housing touches the operator's arm) has a pebble texture ( figure 1 ), and the left and right halves of the housing ( figure 1 ) are manufactured separately and in the slider 11 ( Figure 4 , Figure 5 , Figure 5a , Figure 6 ) is assembled after being placed in it, the slider has a protrusion 12 ( Figure 4 , Figure 5 , Figure 5a , Figure 6 ) and guide section 14 ( Figure 4 , Figure 5 , Figure 5a , Figure 6 ), said protrusion 12 is used to connect to the cylindrical rear portion 8 of the housing 1 ( Figure 4 ) on the internal thread 10, the guide can be along the inside of the housing 1 ( Figure 4 ) of the guide part 5 ( Figure 4 ) to move, the slider passes through the bushing 24 ( Figure 4 , Figure 5 , ...

The invention is intended for use in medicine and enables maximally precise, quick and safe positioning of a coronary stent in the case of uncomplicated and complicated anatomical injuries of the coronary vascular bed, and also when stenting renal and visceral arteries. The claimed device consists of a body with a truncated anterior portion and a cylindrical posterior portion, which are interconnected such that the cylindrical posterior portion of the body is rotatable about its own axis. The inside surface of the cylindrical posterior portion of the body is provided with a thread that is capable of engaging a lip of a slider disposed on guides inside the posterior portion of the body. The slider is connected to a barrel of a gripper having vanes with elastic elements at a delivery systemgripping point such that the gripper is rotatable about its own axis, wherein the vanes of the gripper have protuberances disposed in a clamping cylinder which is arranged inside the body of the device and squeezes and releases the vanes of the gripper under the action of a release member consisting of a pressure surface on the outer truncated portion of the body and vanes arranged inside the bodyat an angle to one another and to the clamping cylinder, respectively releasing or locking the delivery system in the device. When preparing the device for use, the coronary stent is first inserted on a delivery system into the device; the coronary stent is then manually manoeuvred on the delivery system to the injured site of the coronary artery, the delivery system is locked by the vanes of thegripper, and the stent is moved in a longitudinal direction on the delivery system and positioned in the coronary artery by circumferential rotation of the cylindrical posterior portion of the device.
Description
technical field [0001] The invention is suitable for use in medicine, enabling the most precise, rapid and safe positioning of coronary stents in the case of simple or complex anatomical lesions of the coronary bed, in particular in the case of endovascular procedures by means of coronary The stent method recanalizes the part of the artery restricted by the disease to position the coronary stent in the coronary artery. [0002] The device is intended for use in cases of coronary ostium lesions, coronary bifurcation lesions (including left main coronary artery lesions and right coronary ostium lesions), and for "stent-to-stent" implantation to reduce "overlapping regions" ". [0003] The use of this device allows to significantly reduce the radiation exposure of the patient and medical staff as well as the patient's exposure to radiopaque contrast media. [0004] Professionals with no experience in the field of interventional cardiology can easily use the device when conducti...
