Multi-purpose percutaneous puncture channel-building ostomy draining device

Abstract

The invention provides a multi-purpose percutaneous puncturing, channel building, fistulization and drainage device which consists of a pin sheath tube, a pin core, a separable injector interface, a guide wire, multiple layers of passage expansion tubes, working sheath tubes and drainage tubes. The left end of the pin core is provided with a pin core handle; a circular groove is arranged in an internal hole of the pin core handle and is meshed with the left end of the separable injector interface and the left end of the pin sheath; the pin core is inserted in the pin sheath tube; the separable injector interface is arranged in close sliding match at the left end of the pin sheath tube and a convex ring is arranged at the right end of the pin sheath tube; the innermost layer of passage expansion tube is arranged outside the pin sheath and the left end of the tube is connected with the convex ring; the working sheath tubes are arranged outside of the outermost layer of passage expansion tube and the left end of the tube is provided with a handle; the inside diameters of the working sheath tubes are the same as the adjacent multiple layers of passage expansion tubes. Compared with the prior art, the invention can reduce operative complications, improve operative success rate, reduce the work intensity of medical staff and can be applied to minimally invasive operations for various diseases due to the good universality.

Description

1. Technical field [0001] The invention relates to a manufacturing technique of surgical instruments, in particular to a multi-purpose percutaneous puncture tunnel construction and ostomy drainage device. 2. Background technology [0002] Puncture and fistula surgery, drainage surgery, and laparoscopic surgery, which require percutaneous puncture to establish a working channel, are performed in clinical treatment. At present, ordinary surgical instruments such as puncture needles, dilators, and working sheaths are traditionally used. Since the various instruments are not integrated, that is, they do not form a whole device, the deviation of the puncture depth and the expansion depth often occurs, causing complications, and the deviation of the insertion depth of the working sheath and the puncture depth often occurs, resulting in the failure of the establishment of the working channel or Fistula drainage failure, etc. This invention interlocks the mechanical structure of th...
