Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like figure 1 The shown duodenum-jejunum built-in cannula transporter is divided into four parts: head 1 , neck 2 , body 3 and tail 4 from front to back. Wherein, the axial tube 8 runs through the entire conveyor from the beginning to the end, and it is a double-lumen tube, the central lumen accommodates the guide wire to pass through, and the side lumen accommodates the pull wire 13 to pass through. The front end of the side pipe is opened at the developing ring 6, and the pull wire 13 penetrates the axial tube 8 from the opening, and passes through the axial tube 8 to reach the tail end of the conveyor; the axial tube 8 is divided into three sections: front, middle and rear. The front section is socketed with the guide head 5 and the developing ring 6 to form the conveyor head 1 and the neck 2, the rear section is socketed with the rear handle...

Abstract

The invention discloses a design of a conveyor for conveying a duodenum-jejunum embedded casing. The conveyor comprises an axial tube which is longitudinally penetrated from front to back and a guide head, an outer sheath tube, a front handle and a back handle, wherein the guide head, the outer sheath tube, the front handle and the back handle are placed from front to back. Relative sliding of the outer sheath tube and the axial tube is controlled by using the front handle which is provided with a liquid injection port; and the axial tube and a stay wire are fixed by using the back handle. An opening at the front end of a lateral tube cavity of the axial tube is positioned behind the guide head, and the stay wire penetrates into and runs through the axial tube from the opening. In the invention, functions of two conveying modes, such as a pushing mode and a line binding mode, are combined, wherein the pushing function is applicable to releasing an elastic support part of an intestinal casing while the line binding function is applicable to releasing a soft oversleeve part of the intestinal casing.

Description

technical field [0001] The invention relates to a device for delivering a human body implant to a target site, in particular to a delivery device for delivering a duodenum-jejunum built-in cannula. Background technique [0002] Among the various means of treating obesity, interventional therapy is a safer and more effective way than drugs or surgery to lose weight. The so-called interventional therapy is to place metal stents in the intestinal tract to affect the digestion and absorption of food and achieve the purpose of weight loss. There are many kinds of devices for delivering intestinal stents to the intestinal tract, including push-type delivery devices and wire-binding delivery devices for self-expanding stents, and balloon-type delivery devices for non-self-expanding stents. Wherein, when the push conveyor releases the stent, the axial tube is fixed, and the outer sheath is withdrawn, so that the metal stent compressed between the outer sheath and the axial tube esc...
