Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-4 The present invention relates to a plastic stent 10 and a stent handling device 20 as shown in FIG. The plastic stent 10 includes a stent body 2 having a through-through hole 2 a extending along the longitudinal axis of the stent body 2 . The plastic stent 10 is inserted into a blood vessel or an organ of a patient's body and serves to drain bile through the flow hole 2 a of the stent main body 2 .

[0019] Generally, the plastic bracket 10 is manufactured in a straight pipe shape, a curved pipe shape or a straight pipe shape with a hook.

[0020] In this embodiment, internal threads 2 b are formed on the circumferential inner surface of the flow hole 2 a of the holder main body 2 .

[0021] Preferably, the internal thread 2b may be formed on the circumferential inner surface at one end of the flow hole 2a or on the c...

Abstract

Disclosed herein are a plastic stent and a stent operation apparatus for plastic stents. The plastic stent comprises a stent body having a flowing hole passing through the stent body in the longitudinal direction. The stent operation apparatus includes a stent push rod having an externally threaded end. The stent body has an internal thread on the circumferential inner surface of the flowing hole, such that the internal thread is engaged with the externally threaded end. The plastic stent is coupled to the stent push rod by the threaded engagement between the externally threaded end and the internal thread, is inserted into the body of a patient, is adjusted in location by pushing or pulling the stent push rod, and is released from the stent push rod at a correct location in the body of the patient by disengaging the threaded engagement.

Description

technical field [0001] The present invention relates generally to plastic brackets and bracket handling devices, and more particularly to plastic brackets and bracket handling devices threadedly attached to the plastic brackets so that the plastic brackets can be repeatedly withdrawn and retracted from the bracket handling devices to enable precise adjustment of the plastic brackets Implantation site in the patient's body. technical background [0002] In general, various plastic stents have been used, for example, to dilate a constricted blood vessel and keep it in a dilated state, or to dilate various organ ducts, such as bile ducts, esophagus, respiratory tract or urinary ducts, for example due to injuries occurring on organ ducts or Become constricted due to temporary inflammation resulting from injury caused when an endoscope is inserted into an organ duct to treat an injury present in a patient's body. [0003] To implant such a plastic stent into a patient, the plast...
