Example Embodiment
[0023] The essence of tissue penetration with a suture is to pass sutures through both sides of the wound (or other sutures) so that subsequent suture knotting can continue. The invention greatly simplifies the complexity of the tissue penetration action by designing a suture needle and its needle feeding mechanism that can precisely control the autonomous bending trajectory, thereby reducing the overall difficulty of the suture action.
[0024] like image 3 As shown, the first preferred embodiment of the present invention is composed of a needle body 20 , a sink needle tube 30 and a needle feeding mechanism 40 .
[0025] The tubular needle body 20 is made of elastic material with strong restoring force, and the needle body 20 is integrally penetrated into the sink needle tube 30; the push control of the needle feeding mechanism 40 can conveniently realize the action of tissue penetration. The tubular needle body 20 undergoes a heat treatment process, and its distal end (the...
