Embodiment 1

[0041] Example 1 A step-by-step tightening arterial clamp of the present invention

[0042] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an arterial clip that can be tightened step by step according to the present invention. The arterial clip is provided with a pressurized piece 1, a free wire 2 and a reserved coil 3. Described pressure piece 1 is " U " shape, is provided with first pressure piece 11, second pressure piece 12 and connecting arm 13; Described first pressure piece 11 and second pressure piece 12 all It is in the shape of a cuboid; the connecting arm 13 is arc-shaped, and one end is connected to the end of the first pressure sheet 11, and the other end is connected to the end of the second pressure sheet 12; the first pressure sheet 11 The end corresponding to the connection end of the connecting arm 13 is the first pressurizing sheet free end 111, and the first pressurizing sheet free end 111 is provided with a slot 112 inside...

Embodiment 2

[0047] Example 2 A progressive ligation of the carotid artery system of the present invention (1)

[0048]The progressive ligation carotid artery system includes the arterial clip as described in Example 1, and also includes a knot pusher.

[0049] Please refer to Figure 4 , Figure 4 It is a structural schematic diagram of the knot pusher in the progressive ligation carotid artery system of the present invention. Described knot pusher 4 is provided with handle 41; One end of described handle 41 is provided with drag hook bar 42, and the inside of described drag hook bar 42 is hollow; The head end of drag hook bar 42 is provided with drag hook 43, and described The drag hook 43 is in the shape of a hook bent toward the handle; the outer wall of the drag hook rod 42 is provided with a mark 44, and the mark 44 is a dot. The inside of the handle 41 is hollow, and the inner wall is provided with a push-pull slide 45, and the end face of the push-pull slide 45 is wavy sawtoot...

Embodiment 3

[0053] Example 3 A progressive ligation of the carotid artery system of the present invention (2)

[0054] The progressive ligation carotid artery system includes the arterial clip as described in Example 1, and also includes a knot pusher. The knot pusher is a Perclose tuture trimmer produced by Abbott Vascular.

[0055] For Embodiment 2-3, it should be noted that the mark 44 in Embodiment 2 can also be manually marked by the operator; the mark 44 is preferably arranged in the second half region of the hook rod 42 (that is, the part near the handle 41 ), to ensure that the mark 44 is outside the skin of the patient during the operation, which is convenient for the operator to observe; the mark 44 is not limited to a dot, but can be a line segment, a square or other marks; the promotion of the progressive ligation of the carotid artery system of the present invention It is only necessary for the knotter to have the functions of pushing coils and shearing, and is not limited...

Abstract

The invention provides an artery clamp capable of tightening step by step. The artery clamp comprises a pressing piece, a reserved coil with multiple slip knots and a stray line marked with indicating graduations, the pressing piece comprises a first pressing piece body and a second pressing piece body, a slot is arranged on the first pressing piece body, a fixing through hole is arranged on the second pressing piece body, the reserved coil is fixed on the second pressing piece body, a plug pin matched with the slot is arranged at one end of the stray line, and the other end of the stray line penetrates out of the reserved coil via the fixing through hole. The invention further provides a progressive carotid artery ligation system which comprises the artery clamp and a knot guide. Using the progressive carotid artery ligation system for parent artery occlusion needs no reopening a wound, secondary operation and anesthetization are avoided, risks of operative complications can be reduced, operative incision healing time is shortened, operative and hospitalization expenses are saved, and pain of a patient is relieved; the pressing piece of the artery clamp is made of biocompatible materials and is non-toxic to human tissues; and the artery clamp is simple in integral structure, low in cost and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an arterial clip that can be tightened step by step and a progressive ligation carotid artery system. Background technique [0002] Intracranial aneurysm is a common cerebrovascular disease, the latest brain magnetic resonance angiography (magnetic resonance angiography, MRA) study confirmed that its incidence rate is about 10%. Once bleeding occurs, it has a high rate of death and self-mutilation. According to the size of the aneurysm, it can be divided into small, large and giant aneurysms; according to the shape, it can be divided into saccular aneurysm, serpentine aneurysm, dissection aneurysm and so on. Surgical clipping is a common treatment method for small and some large saccular aneurysms; for giant and some large aneurysms and complex aneurysms such as serpentine aneurysms, direct surgical clipping is more difficult, although more and more Many intracranial an...
