Description

Technical Field

[0001] The utility model relates to the technical field of medical tools, in particular to a Y-shaped connector for preventing an exchange guide wire from falling off. Background Art

[0002] The Y-type connector or Y-valve used in neurointerventional surgery is a product made of medical polymer materials and is a disposable sterile medical device, usually used to guide, place and lock catheter guidewires. During interventional treatment, such as heart stent surgery, it is usually necessary to use a Y-type connector to connect to the guide tube. Balloons, stents and other interventional devices need to be guided into the guide tube through the guide wire. However, during the guidance process, the guide wire needs to be pressed with the fingers. When the operator does not insert the guide wire correctly, or does not fix or press the guide wire correctly during the operation, the guide wire will be brought into or out of the guide tube due to friction and other reasons, which can easily cause blood vessel or coronary artery perforation, or the guide wire needs to be reinserted, etc. This can further lead to the failure of the operation and even endanger the patient's life. Utility Model Content

[0003] The technical problem to be solved by the present technical solution is that the existing Y-type connector still has the problem that the guide wire cannot be double-locked and prevented from falling out.

[0004] To achieve the above objectives, the present invention creates a technical solution: a Y-shaped connector that prevents the exchange guide wire from falling off, comprising an inner lumen tube with a hemostatic locking valve and a guide joint respectively provided at the front and rear ends, an injection joint connected to the inner lumen tube is obliquely provided on the side of the inner lumen tube, and a wire fixing rib plate is provided between the inner lumen tube and the injection joint; an adjustment groove parallel to the inner lumen tube in the length direction is provided in the wire fixing rib plate, and a through groove connected to the adjustment groove is provided on the side of the inner lumen tube close to the adjustment groove; a wire fixing part for fixing and adjusting the guide wire inside the inner lumen tube is provided in the adjustment groove and the through groove.

[0005] The beneficial effects of the technical solution are as follows: a wire fixing rib plate is provided between the injection connector and the inner cavity tube, and an adjusting groove is provided on it; a through groove connected to the adjusting groove is also provided, and the guide wire in the inner cavity tube is re-fixed by means of the wire fixing parts provided in the adjusting groove and the through groove, which is not only convenient for the staff to hold and operate, but also can stably and efficiently realize multiple locking of the guide wire, further improving the safety of the surgical application of the Y-type connector.

[0006] The present invention creates an improved technical solution: an elastic reset layer is arranged between the inside of the inner cavity tube and the bottom of the through groove, and the wire fixing part includes a slider and a wire fixing pressure block arranged at the bottom of the slider; the slider slides in the through groove and the bottom end of the wire fixing pressure block is arranged on the elastic reset layer, and the adjustment sliding surface at the top of the slider is arranged on the side of the adjustment slide groove; an adjustment rod that can slide along its length direction is arranged in the adjustment slide groove, and the bottom of the adjustment rod is in contact with the adjustment sliding surface.

[0007] The beneficial effects of the improved technical solution are as follows: the slider is arranged in the through groove, and the adjusting sliding surface on its top is arranged in the adjusting groove. When the adjusting rod moves back and forth in the adjusting groove, it will squeeze one end of the slider, causing it to slide up and down in the through groove; when the slider moves downward, the wire fixing pressure block at its bottom will squeeze the elastic reset layer to deform, and finally the bottom of the wire fixing pressure block will press one side of the guide wire through the elastic reset layer, thereby realizing rapid fixation of the guide wire.

[0008] The present invention creates an improved technical solution: the adjusting rod includes a sliding rod arranged in an adjusting groove and one side of which is in contact with an adjusting sliding surface; a screw is arranged at one end of the sliding rod, and the screw cooperates with a fastening nut arranged on one side of the wire reinforcement plate; a limited end is arranged at the other end of the screw on the other side of the wire reinforcement plate, and the fastening nut, the screw and the limited end cooperate to achieve the fastening of the adjusting rod on the adjusting groove.

[0009] The beneficial effect of the improved technical solution is as follows: when the guide wire is pressed and fixed by the wire fixing block, the fastening nut at one end of the adjusting rod can be rotated so that the screw rod at one end thereof cooperates with the fastening nut to be tightened; and since the other end of the sliding rod is set at a limiting end on the other side of the wire fixing rib plate, the wire fixing part can be fixed on the adjusting slide groove to achieve continuous tightening of the guide wire.

[0010] The improved technical solution adopted by the present invention is as follows: a roller is arranged on the outer side of the fastening nut, and an anti-slip protrusion is arranged on the outer ring of the roller.

[0011] The beneficial effect of the improved technical solution is that a roller is provided on the fastening nut for easy rotation by the staff, and a stable and convenient tightening operation can be achieved in combination with the anti-slip protrusion.

[0012] The improved technical solution adopted by the present invention is as follows: the elastic reset layer is a rubber film at the bottom of the sealing groove.

[0013] The improved beneficial effect of the technical solution is that the elastic reset layer is specifically a rubber film that can stably seal and appropriately deform and reset.

[0014] The improved technical solution adopted by the present invention is as follows: retaining edges for limiting the wire fixing pressure block from escaping outward from the through groove are arranged on both sides of the connection between the sliding block and the wire fixing pressure block.

[0015] The improved technical solution has the following beneficial effects: in order to prevent the elastic reset layer from rebounding too much, the wire fixing block is driven to push the slider out of the through slot, and a retaining edge is provided to cooperate with the bottom of the through slot to limit the position.

[0016] The improved technical solution adopted by the present invention is as follows: a cushion block cooperating with the wire fixing block to press the guide wire is arranged on the inner wall of the inner cavity tube at the opposite side of the through groove; one end of the cushion block is connected to the end face of the inner cavity tube.

[0017] The beneficial effect of the improved technical solution is: in order to avoid the need to press the slider down too deeply to fix the guide wire in the inner cavity tube, a pad block protruding to one side of the slider is provided, so that the wire fixing block can more easily support and fix the guide wire.
