Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0018] The following definitions of directions are all defined according to the directions observed by the user when holding the single-handed stent transporter.

[0019] like Figure 1 to Figure 3 The one-handed stent delivery device shown mainly includes a housing 1, a catheter 4, a sheath 5, a front end 6, a pushing mechanism 8, and the like.

[0020] Wherein, a cavity 13 is formed in the casing 1 for installing other parts of the conveyor. One end (ie, the fixed end) of the conduit 4 is fixed in the casing 1 , and its other end (ie, the free end) extends out of the casing 1 ; the front end 6 is arranged at the free end of the conduit 4 . The sheath tube 5 is slidably sheathed outside the catheter 4 , one end of which is located inside the casing 1 and the other end also extends outside the casing 1 . Push mechanism 8 is slidably installed on h...

Abstract

The invention relates to a one-hand stent conveyer, comprising a shell, a guide tube fixed at one end into the shell, a front end arranged at one end of the guide tube, and a sheath slidably sleeving the guide tube, and also comprising two travel retainers fixed in the shell and extending along the guide tube as well as a push mechanism slidably mounted on the shell and fixed to the sheath; the other end of the guide tube at least runs through one travel retainer and extends out of the shell; the push mechanism includes a travel plate slidably mounted in the shell and positioned between the two travel retainers, a sheath support fixed to the travel plate and connected with the sheath and a travel push-button connected with the travel plate and extending out of the shell. The one-hand stent conveyer is simple in structure and low in cost and can provide longer life for the shell.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a delivery device, in particular to a single-handed vascular stent delivery device. Background technique [0002] In recent years, interventional therapy has developed rapidly due to its advantages of minimal trauma and high efficiency. The effect and significance of interventional therapy in the treatment of cardiovascular diseases is very important. Lower limb vascular stent implantation is the Very effective approach for vascular disease. Lower extremity vascular stents are generally self-expanding stents made of superelastic materials. During stent surgery, the stent is delivered into the blood vessel under the guidance of medical imaging technology, and then the stent is stretched to make the blood vessel thicker and allow blood to pass through. achieve the purpose of treatment. [0003] The existing stent delivery devices are generally complex in structure, cumbersome to op...
