Description
Technical field
The utility model relates to a kind of guidance protection pipes more particularly to a kind of choledochoscope to guide protection pipe.
Background technique
Choledochoscope is the common medical instrument of biliary tract disease inspection and treatment, instrument have rigid mirror and soft mirror it
Point, rigid mirror can only observe choledochus, and soft mirror can send scope to 2~3 grades of common hepatic ducts, therefore mostly use soft biliary tract at present
Mirror.Usual choledochoscope enters biliary system by the Trocar of surgical incision, since choledochoscope is softer, so in the course of surgery
Choledochoscope front end is not easily shifted；And choledochoscope surface is easy to damage, when being taken out choledochoscope with choledochoscope gripper clamp, is easy to damage gallbladder
Road mirror surface.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of choledochoscope guidance protection pipe.
To achieve the above object, the utility model provides following technical solution: a kind of choledochoscope guidance protection pipe, including
One hollow pipe, the hollow pipe include straight tube and bend pipe, and by bend pipe endface, internal diameter is gradually increased the bend pipe backward；Gallbladder is set
Road mirror guidance protection pipe facilitates being placed and taken out for choledochoscope；The design of the hollow pipe leading portion bend pipe is convenient for the shifting of choledochoscope front end
It is dynamic；One section of the hollow pipe front keeps hollow pipe front end smaller by the design that internal diameter is gradually increased backward of bend pipe end, back end inside diameter
It is larger, it avoids choledochoscope front end from shaking at nozzle, influences choledochoscope mobile accuracy, while choledochoscope being facilitated to pick and place and reduce gallbladder
Friction of the road mirror in pick-and-place and use process between hollow pipe reduces choledochoscope damage risk.
The utility model is further arranged to, and the hollow pipe is gradually increased by bend pipe end face to straight tube end face internal diameter；Make
Lines gradual change is smooth inside hollow pipe pipe, is further reduced during picking and placing choledochoscope and causes to damage to choledochoscope.
The utility model is further arranged to, and the bend pipe is upwarped relative to straight tube, and the highest point of the bend pipe end is not
Higher than the highest point of the straight tube end, avoid for cater to the bending of bend pipe opened up on human body excessive channel accommodate it is hollow
Pipe, while also avoiding the width in medical staff channel not easy to control.
The utility model is further arranged to, and straight tube end face internal diameter is 8-12mm, and bend pipe end face internal diameter is
5.5-6.5mm, straight tube end face internal diameter are 10mm, and bend pipe end face internal diameter is 6mm；Straight tube end face internal diameter is the side of being 10mm
Just the best hollow pipe diameter operated；Bend pipe end face internal diameter is 6mm, is avoid choledochoscope from shaking in hollow pipe best straight
Diameter.
The utility model is further arranged to, and the bend pipe end face is obliquely installed relative to straight tube, the bend pipe end face court
To identical with elbow curvature direction；Such setting makes medical worker in the course of surgery, the bending direction of bend pipe and bend pipe end face
Direction tend towards medical worker, more meet operating habit；Also avoid choledochoscope in the course of surgery by bend pipe pipe simultaneously
Mouth scratches.
The utility model is further arranged to, and the angle between the bend pipe end face and straight tube axis is 30-60 degree, described
Angle between bend pipe end face and straight tube axis is 45, and bend pipe notch is avoided to be excessively sharp and accidentally injure human body.

Specific embodiment
It is further illustrated below with reference to a kind of embodiment of choledochoscope guidance protection pipe of Fig. 1 to 5 pairs of the utility model.
To achieve the above object, the utility model provides following technical solution: a kind of choledochoscope guidance protection pipe, including
One hollow pipe 1, the hollow pipe 1 include straight tube 11 and bend pipe 12, and internal diameter is gradually backward by bend pipe endface 123 for the bend pipe 12
Increase, in the utility model, protruding into the intracorporal one end of people is front end；In use, choledochoscope is put into hollow pipe 1, then again will
Choledochoscope protrudes into biliary system from Trocar together with hollow pipe 1 and performs the operation, in surgical procedure, before needing mobile choledochoscope
When the position at end, hollow pipe 1 is rotated, the bend pipe end face of hollow pipe front is mobile, to drive choledochoscope mobile.
Further, the hollow pipe 1 is gradually increased by internal diameter at bend pipe end face 123 to straight tube end face 113；Make hollow
Lines gradual change is smooth inside 1 pipe of pipe, is further reduced during picking and placing choledochoscope and causes to damage to choledochoscope.
Further, the bend pipe 12 is upwarped relative to straight tube 11, and bend pipe end highest point 121 is straight not higher than described
Tube end highest point 111；"upper" and " highest point " herein refers under the laid-flat status as shown in Figure 1 of hollow pipe 1 in general sense
"upper" and " highest point ".
Further, 113 internal diameter of straight tube end face is 8-12mm, and 123 internal diameter of bend pipe end face is 5.5-6.5mm,
113 internal diameter of straight tube end face is 10mm, and 123 internal diameter of bend pipe end face is 6mm；113 internal diameter of straight tube end face is the side of being 10mm
Just 1 diameter of best hollow pipe operated；123 internal diameter of bend pipe end face is 6mm, is that choledochoscope is avoided to shake most in hollow pipe 1
Good diameter.
Further, the bend pipe end face 123 is obliquely installed relative to straight tube 11,123 direction of bend pipe end face and curved
12 bending direction of pipe is identical；Such setting makes medical worker in the course of surgery, the bending direction of bend pipe 12 and bend pipe end face 123
Direction tend towards medical worker, more meet operating habit；Also avoid choledochoscope in the course of surgery by bend pipe 12 simultaneously
Nozzle scratches.
Further, the angle between 11 axis of the bend pipe end face 123 and straight tube is 30-60 degree, the bend pipe end face
Angle between 123 and 11 axis of straight tube is 45, and 12 notch of bend pipe is avoided to be excessively sharp and accidentally injure human body.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
