Embodiment 1

[0048] Embodiment 1 provides an interventional medical device 10 for interventional treatment.

[0049] Please also refer to figure 1 , figure 2 , Figure 3a and Figure 3b , the interventional medical device 10 includes an interventional medical device 110 and a delivery cable 200 . Instrument 110 includes a plug head 120 located on interventional medical instrument 110 . The delivery cable body 200 includes a cable head 220 located on the delivery cable body 200 . The delivery cable 200 is used to transfer the interventional medical device 110 to a selected position, and the cable head 220 is disposed on the distal end 210 of the delivery cable 200 . The bolt head 120 includes a first thread 122 and a first stop portion 121a; the cable head 220 includes a second thread 222 and a second stop portion 221a that can be connected with the first thread 122; the bolt head 120 and the cable head The detachable connection between the parts 220 is through the first thread 122 a...

Embodiment 2

[0059] Embodiment two, see Figure 5a , Figure 5b with Figure 5c , the interventional medical device 10b provided in this embodiment is substantially the same as the interventional medical device 10, except that the shapes and installation positions of the first stopper 121b and the second stopper 221b are different from those of the first stopper 121 a and the second stop portion 221 a in shape and location, and the structure of the plug head 120 b is different from that of the plug head 120 . Specifically, on the proximal outer wall 125b of the bolt head 120b and on the distal outer wall 224b of the cable head 220b, the proximal end surface 123b protruding from the bolt head 120b and the distal end of the cable head 220b are correspondingly provided. The protrusions on the end surface 223b are used to form the first stop portion 121b and the second stop portion 221b. In this embodiment, the first stopper part 121b and the second stopper part 221b can be integrally forme...

Embodiment 3

[0065] Embodiment three, see Figure 6a , Figure 6b with Figure 6c , the difference from Embodiment 1 and its modified embodiments is that Figure 6a , Figure 6b with Figure 6c In the illustrated embodiment of the interventional medical device 10c, a first stopper portion 121c and a second stopper portion 221c are correspondingly provided on the proximal end surface 123c of the plug head 120c and the distal end surface 223c of the cable head 220c. The first stop portion 121c and the second stop portion 221c have sharp angles, and the angle of the sharp angle is smaller than the screw-in angle when the first thread 122c and the second thread 222c engage. Such as Figure 6b A second screw thread 222c is provided on the outer wall of the cable head 220c shown, and a protrusion with a sharp angle is set on the distal end surface 223c of the cable head 220c as the second stopper 221c, and the sharp angle of the protrusion is 9 less than The screw-in angle when the first t...

Abstract

The invention relates to an intervention medical apparatus for intervention treatment, an intervention medical instrument and a conveying cable body of the intervention medical instrument. The intervention medical apparatus comprises an instrument having a bolt head part and a conveying cable body having a cable head part; the bolt head part is provided with a first thread; the cable head part is provided with a second thread engaged with the first thread; a near end of the bolt head part is equipped with a first baffle part; a far end of the cable head part is provided with a second baffle part; the bolt head part and the cable head part are detachably connected via the first thread and the second thread; and when the first baffle part is abutted against the second baffle part, the first thread and the second stop engaging. Intervention medical apparatus safety can be enhanced; and the intervention medical instrument can be normally released.

Description

technical field [0001] The present invention relates to the field of interventional medical devices, in particular to an interventional medical device placed at a selected part of the human body, a delivery cable for transporting the interventional medical device to the selected part, and a delivery cable including the interventional medical device and delivery cable. Cable body interventional medical device. Background technique [0002] Interventional therapy refers to a method of completing the treatment of diseases without surgery through the catheter delivery of materials, medical devices and drugs to the treatment site under the guidance of certain medical imaging equipment. At present, interventional therapy has become one of the three major modern medical treatments alongside traditional medical treatment and surgical treatment. Cardiac and vascular diseases are the most widely used fields of interventional therapy. [0003] Compared with traditional medical drug t...
