Description

Inner sleeve for choledochoscope

Technical Field

The utility model relates to a cholangioscope field especially relates to an interior sleeve pipe for cholangioscope.

Background

The choledochoscope is mainly used for endoscopic examination and endoscopic surgery of the hepatobiliary duct. A hole needs to be punctured in the abdomen of the patient, and a choledochoscope and a surgical instrument are put in the hole through puncturing, and the choledochoscope can shoot images of the surgical site, so that a doctor can conveniently monitor the surgical operation on a display.

If current cholangioscope need use the holmium laser machine to carry out the biliary calculus rubble in the operation, some doctors can directly use holmium laser fiber inserts the cholangioscope, if doctor's misoperation like this will make on the laser hits the mirror surface of cholangioscope to damage the mirror surface of cholangioscope, and then produce huge maintenance cost, a cholangioscope need be changed even to serious, and the cost of consumption is higher. Some doctors can use 5F ureteral catheters in urology surgery to be inserted into the choledochoscope as inner sleeves and then insert holmium laser fibers from the ureteral catheters to protect the choledochoscope, but because the ureteral catheters are made of hard materials and the choledochoscope needs to be bent to adapt to a human body, after the choledochoscope is used for several times, the bent part of the choledochoscope can be broken by the hard ureteral catheters, so that the choledochoscope leaks water, and the choledochoscope is damaged; the maintenance cost and the maintenance time are increased, and the normal work of the hospital is greatly influenced. Therefore, there is a great need for an inner sleeve that is specifically adapted to and can protect a choledochoscope.

SUMMERY OF THE UTILITY MODEL

Preferably, the inner wall of the hard tube is used for fixing the holmium laser fiber, and the inner diameter of the hard tube is 10 micrometers larger than the outer diameter of the holmium laser fiber.

Preferably, a mark part is arranged on the hard tube, and the color of the mark part is different from that of the soft tube. The length of the exposed hard tube is not less than 1.5cm when a doctor installs and takes the inner sleeve.

Preferably, the flexible pipe is made of a silica gel material.

Compared with the prior art, the beneficial effects of adopting the technical scheme are as follows: the utility model discloses an interior sleeve pipe for cholangioscope, including interconnect's soft pipe and hard pipe, soft pipe is used for nestification in the cholangioscope, hard pipe is used for exploring cholangioscope, soft pipe with hard pipe is seamless connection. The soft pipe can be crooked in order to adapt to the human body, can prevent that the dactyloscope that the flexion was damaged when the operation in-process is operated repeatedly from leaking that leads to, and the hard pipe can pull open the distance of holmium laser and cholangioscope terminal surface simultaneously, can avoid the holmium laser to damage the cholangioscope mirror surface. The choledochoscope is protected.

Description of the symbols of the main elements: 1. a choledochoscope; 2. a flexible tube; 3. a rigid tube; 4. a holmium laser fiber.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings. In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1: referring to fig. 1 and 2, an inner cannula for a choledochoscope of the present embodiment includes a soft tube 2 and a hard tube 3 connected to each other, the soft tube 2 is used to be nested in the choledochoscope 1, the hard tube 3 is used to extend out of the choledochoscope 1, and the soft tube 2 and the hard tube 3 are connected seamlessly. The soft tube 2 can be crooked in order to adapt to the human body, can prevent that the flexion of choledochoscope 1 when the operation in-process is operated repeatedly 1 choledochoscope 1 that the flexion was damaged and is leaded to from leaking water, and the holmium laser can be avoided destroying 1 mirror surface of choledochoscope to the distance of the 1 terminal surface of holmium laser can be drawn back to hard tube 3 simultaneously. The choledochoscope 1 is protected.

Example 2: referring to fig. 1, the length of the hard tube 3 of this embodiment is not less than 1.5cm, so that the distance between the holmium laser and the end surface of the cholangioscope 1 is not less than 1.5cm, and if the length is less than 1.5cm, the holmium laser may reflect to the mirror surface of the cholangioscope 1, and further damage the cholangioscope 1.
