Embodiment 1

[0045] A sealing and locking device, such as figure 1 As shown, it includes an inner part 1, an outer part 2, and a sealing and locking mechanism 3. The sealing and locking mechanism 3 is sleeved outside the inner part 1 and connected to the proximal area of ​​the outer part 2; There are two sets of sliding fit structures inside the sealing and locking mechanism 3, such as Figure 2-5 As shown, the sliding fitting structure includes a first group of sliding fitting structures 4 and a second group of sliding fitting structures 5; wherein, the first group of sliding fitting structures 4 is located in the proximal area of ​​the second group of sliding fitting structures 5 or outside the near-end area; after the first set of sliding fitting structures 4 achieves the mating state, it then drives and triggers the second group of sliding fitting structures 5 to form a sliding fit, so that the built-in Part 1 and said external part 2 have dual functions of sealing and locking relativ...

Abstract

The invention relates to the field of medical instruments, in particular to a sealing and locking device. The sealing and locking device comprises an internal part, an external part and a sealing and locking mechanism; the sealing and locking mechanism is arranged outside the internal part in a penetrating and sleeving mode and connected to the near-end area of the external part; two sets of sliding fit structures are arranged in the sealing and locking mechanism and comprise the first set of sliding fit structures and the second set of sliding fit structures. wherein the first set of sliding fit structures is positioned in a near-end area of the second set of sliding fit structures or outside the near-end area; and after the first set of sliding fit structures realizes the matching state, the second set of sliding fit structures are driven and triggered to form sliding fit, so that the double functions of sealing and locking of the internal part and the external part at any time and at any relative position can be quickly realized through one-step operation.

Description

[0001] The invention belongs to the field of medical instruments, and in particular relates to a sealing and locking device. Background technique [0002] At present, interventional therapy is an emerging treatment method between surgery and medical treatment, including endovascular intervention and non-vascular intervention. After more than 30 years of development, it has now been called the three pillar disciplines together with surgery and internal medicine. To put it simply, interventional therapy is to make a small channel with a diameter of several millimeters on the blood vessel or skin without exposing the lesion, or through the original pipeline of the human body, in the imaging equipment (angiography machine, fluoroscopy machine, CT, MR). , B-ultrasound) to treat the local lesion under the guidance of the least traumatic treatment. [0003] In the prior art, the delivery system for minimally invasive interventional treatment of structural heart disease, including at...
