One section of outer indwelling for achieving the purpose that remove patient's body toxin toward Peritoneal Infusions and drainage peritoneal dialysis liquid.
Clinically, currently used peritoneal dialysis tube placing operation is surgical sectioning method.Simplified process is as follows: selecting to close on stomach wall
Suitable approach does notch, and skin is cut after anesthesia, and blunt separation subcutaneous tissue is until theca of rectus abdominis muscle;Theca of rectus abdominis muscle does stringer
Small notch, subsequent blunt separation rectus aabdominis cut peritonaeum for the saturating pipe abdomen inner segment of abdomen and are put into Douglas nest until peritonaeum;Between breaking joint
Theca of rectus abdominis muscle is closed, deep layer terylene is placed in outside peritonaeum, the sheath of rectus is interior or lower section;The saturating pipe outlet port of abdomen is marked on skin, is led
Pipe hypodermic tunnel makees local anaesthesia, with tunnel guide traction conduit the saturating pipe exit marking of subcutaneous fat traveling abdomen skin just under
Side punctures skin extraction abdomen and manages thoroughly;Subcutaneous tissue and skin are sutured after cleaning a wound.
In operating process, existing peritoneal dialysis tunnel guide, since its diameter is relatively thick (5-8mm), therefore its syringe needle is generally all
It is more blunt;It is pushed up when operation from inside toward outside, when passing through skin, syringe needle is blunt and exports away from handgrip part farther out, takes very much
Power;If increasing power, when tunnel guide passes through skin, it is difficult to control direction, easily hurts operator.
Utility model content
The purpose of the utility model is to provide a kind of novel peritoneal dialysis tunnel guides, are divided into outer segment and inner segment, inner segment
After completing subcutaneous puncture, outer segment is used to wear out skin and then the head end of inner segment is cooperatively connected smoothly by tunnel guide and peritoneal cavity
Outside lead body;Effectively avoid drawback caused by being not easy to be pierced by skin in the prior art.
To achieve the goals above, the technical scheme adopted by the utility model is that: a kind of novel peritoneal dialysis tunnel guide,
Including inner segment and outer segment two parts;Wherein:
Inner segment is hollow arc needle body, and both ends are respectively side a and b;
The end A is head end, and the head end is blunt nosed;It is equipped with the aperture of a back taper at the top of the head end, is set on aperture inner wall
There is internal screw thread, for being cooperatively connected with outer segment;
The end B is tail end, and diameter is slightly less than the diameter of puncture needle, for connecting with the saturating pipe of abdomen;
Outer segment, it is T-shaped, it is made of handle and spine end;
The handle and spine end are vertically arranged, and the spine end can be inserted into the head end and be flexibly connected with head end.
A kind of novel peritoneal dialysis tunnel guide as described above, wherein the length of the arc needle body is 5-10cm, straight
Diameter is 0.5-1cm;
The radian of the arc needle body is 90-10 degree.
A kind of novel peritoneal dialysis tunnel guide as described above, wherein the length of the head end is 0.5-1cm;Its diameter
For 0.25-0.5cm.
A kind of novel peritoneal dialysis tunnel guide as described above, wherein the handle is equipped with antiskid thread, the length is
0.5-3cm。
A kind of novel peritoneal dialysis tunnel guide as described above, wherein the inner segment and outer segment are all made of medical stainless steel
It is made.
Compared with prior art, the beneficial effect that the utility model generates is mainly reflected in:
A kind of novel peritoneal dialysis tunnel guide of the utility model comprising two parts, inner segment penetrate subcutaneously for tunnel
Out of shape, outer segment punctures after skin is docked with inner segment realization and pulls out tunnel guide and peritoneal cavity in vitro;
A kind of novel peritoneal dialysis tunnel guide of the utility model, avoids arduously pushing inner segment in the prior art effectively to wear
Skin is crossed, while can avoid operator and being accidentally injured when using very big power.
A kind of novel peritoneal dialysis tunnel guide of the utility model, effectively improves peritoneal dialysis tube placing operation and establishes hypodermic tunnel
Efficiency.
