Problems solved by technology

[0003] Introducer sheath is a device used in vascular interventional diagnosis and treatment to establish percutaneous access for other intravascular devices. It uses puncture technology to place the sheath into the blood vessel under the guidance of a guide wire. However, the sheath used in current medical methods Often it only has the function of hemostasis and conduction. When the guide wire slides in the sheath, once the end of the guide wire or contrast fluid tube falls off the device, it is likely to enter the blood vessel from the sheath, causing very serious medical accidents

Embodiment 1

[0024] see Figure 1 ~ Figure 2 , a treatment device for cardiovascular interventional surgery, including a sheath tube shell 1, a filling cavity 4, a protection cavity 5 and an anti-falling mechanism 8, wherein the inside of the sheath tube shell 1 is provided with a filling cavity 4, and the upper right corner of the filling cavity 4 A protective cavity 5 is provided, and an anti-falling mechanism 8 for preventing the guide wire from falling off is installed inside the protective cavity 5. The anti-falling mechanism 8 includes a movable handle 10, a connecting rod 15, a curved connecting rod one 16, a curved connecting rod two 18, Strut 20 and block 22, wherein movably installed movable handle 10 top is movably connected with connecting rod 15, and the left side of connecting rod 15 is connected with the curved connecting rod one 16 that fixed axis rotates, and the left side of curved connecting rod one 16 is connected There is a curved connecting rod 2 18 rotating on a fixe...

Embodiment 2

[0029] see image 3 , a treatment device for cardiovascular interventional operations, its main structure is the same as that of Embodiment 1, and the sheath tube shell 1 is improved, and a fixed shell 23 is installed outside the sheath tube shell 1, and the fixed shell 23 is connected below Binding belt 24 is arranged, and binding belt 24 ends are equipped with mother-in-law glue 25.

[0030] The working principle of the present invention is: when performing an interventional operation on a patient, the sheath tube is wound back and forth on the affected part of the patient through the binding band 24 , and the binding band 24 is fixed by the mother-in-law adhesive 25 .

[0031] The advantage of this embodiment is that the sheath tube can be fixed on the affected part of the patient through the binding band 24, so as to prevent the sheath tube from falling off and shifting during the operation and affecting the normal intervention process.

Abstract

The invention discloses a treatment device for cardiovascular interventional surgery, which belongs to the technical field of interventional surgery, and comprises a sheathing canal shell, a filling cavity, a protection cavity and an anti-falling mechanism, the filling cavity is arranged in the sheathing canal shell, the protection cavity is arranged at the right upper corner of the filling cavity, and the anti-falling mechanism for preventing a guide wire from falling is arranged in the protection cavity. The anti-falling mechanism comprises a movable handle, a connecting rod, a first curvedconnecting rod, a second curved connecting rod, a supporting rod and a clamping block, the upper portion of the movable handle is movably connected with the connecting rod, the left side of the connecting rod is connected with the first curved connecting rod rotating around a fixed shaft, the left side of the first curved connecting rod is connected with the second curved connecting rod rotating around the fixed shaft, the clamping block is arranged at the left side of the second curved connecting rod, the clamping block slides in the vertical direction, and the top of the clamping block is movably connected with the second curved connecting rod through the supporting rod. The anti-falling mechanism is additionally arranged on the right side of a sheathing canal, so that the situation thata guide wire accidentally falls into a blood vessel in the operation process to threaten the life of a patient can be effectively prevented, and the operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of interventional surgery, in particular to a treatment device for cardiovascular interventional surgery. Background technique [0002] Cardiovascular interventional surgery is the technique of inserting catheters from peripheral blood vessels and sending therapeutic devices to the heart and large blood vessels to achieve clinical electrophysiological examinations and certain heart diseases, such as atherosclerosis and blood embolism in the circulatory system. It is a minimally invasive surgical treatment. [0003] Introducer sheath is a device used in vascular interventional diagnosis and treatment to establish percutaneous access for other intravascular devices. It uses puncture technology to place the sheath into the blood vessel under the guidance of a guide wire. However, the sheath used in current medical methods Often it only has the function of hemostasis and conduction. When the guide wire slides i...
