Technical Field
The utility model relates to a medical operating mirror, in particular to a choledochoscope with a mirror sheath in the minimally invasive surgery for protecting the gallbladder and removing the stones.
Background
The traditional concept considers that the gallbladder has no important function and can be optional, the gallbladder calculus can not recur after the gallbladder is cut off, and the cancer of polyps can not be worried about, so the cholecystectomy is gradually considered as the most ideal method for treating the gallbladder calculus and the gallbladder polyps. However, with the development of medicine and the disintegration of minimally invasive concepts, the important physiological functions of the gallbladder are as follows: 1. a storage function; 2, a contraction function; 3, a concentration function; secretion function; 5, immune function; 6, having important influence on digestion function; the important regulation function for the pressure of the biliary tract fluid is gradually paid attention. Furthermore, the patient is not "anxious" about being high after the gallbladder has been removed, as removal of the gallbladder can cause a number of adverse consequences, including: 1. dyspepsia; reflux of digestive juice including reflux gastritis and reflux esophagitis; increased incidence of common bile duct stones; increased bile duct injury rate; 5. increased incidence of colon cancer; 6. post-cholecystectomy psychological disorders; 7. postcholecystectomy syndrome, and the like. Cholecystectomy is slowly beginning to shake passively as the gold standard for the treatment of gall bladder stones. Therefore, the treatment of the gallbladder is more and more emphasized nowadays, and the choledochoscope with the choledochoscope is mainly used for treating the cholelithiasis. The structures of some choledochoscopes with sheath are also disclosed in the present published documents, such as chinese patent: "get biliary tract mirror (CN 201542684U) of stone area mirror sheath", constitute by stereoplasm mirror body and three leaves stone valve of getting, stereoplasm mirror body in be provided with light source optic fibre, camera and optical fiber, stereoplasm mirror body is 120 degrees angle circular arc transition bending in the axial, be provided with the telescopic link along the axial in the stereoplasm mirror body, the root of three leaves stone valve of getting sets up the front end at the stereoplasm mirror body through hinge structure, the middle part of three leaves stone valve of getting is connected with the front end of telescopic link, the rear end and a trailing arm of telescopic link are connected, the trailing arm is connected with a manipulation handle through the round pin axle, the manipulation handle passes through the round pin axle and sets up on the stereoplasm mirror body. However, the structure of the choledochoscope with the sheath is too complicated.
Disclosure of Invention
The utility model provides a choledochoscope with a choledochoscope which has simple structure, utilizes the pressure difference to quickly clean the broken stones in the choledochosis and is convenient to operate; the choledochoscope solves the technical problems that the choledochoscope in the prior art is complex in structure, inconvenient in broken stone cleaning and inflexible in operation.
The above technical problem of the present invention is solved by the following technical solutions: the utility model provides a take cholangioscope of mirror sheath, includes the speculum, and the speculum includes mirror tube and mirror tube main part, is equipped with working channel and image channel at mirror tube intraductal, the one end of mirror tube main part be connected with the mirror sheath through connecting the lock, the other end of mirror tube main part be equipped with the inlet, the mirror sheath include the sheath pipe, be connected with the liquid outlet on the sheath pipe wall, the sheath pipe cup joints outside the mirror tube, when unblock mirror sheath, the mirror tube is retreated to the rear side of liquid outlet, sheath pipe and liquid outlet form liquid outlet channel. In the working channel, stones in the gall bladder are broken by using the tool, and in the operation process, physiological saline is continuously injected into the gall bladder through the liquid inlet, so that the gall bladder is always full and transparent, and the operation is convenient. Then the liquid outlet of the endoscope sheath is connected with the suction device, the connecting lock can be unlocked during operation, the endoscope is rapidly retreated, the endoscope sheath is kept still, and instant pressure difference is formed between the inside and the outside of the gallbladder, so that the crushed stone in the gallbladder can flow out along a liquid outlet channel formed by the sheath tube and the liquid outlet, the operation effect is ensured, and the stone is rapidly discharged.
Preferably, the main body of the mirror tube is provided with a light guide beam interface, and a light guide beam channel is arranged outside the working channel and the image channel in the mirror tube. The instrument can be placed in the working channel arranged in the endoscope tube, the image channel transmits observed images, the light guide beam channel is the rest part except the two channels in the endoscope tube, and the light guide beam channel illuminates through the light guide beam to ensure the definition of the images.
Preferably, one end of the lens tube main body is connected with a lens tube, the other end of the lens tube main body is provided with a working channel inlet, the lens tube main body is provided with two liquid inlets, the two liquid inlets are positioned on the same straight line, and the liquid inlets are perpendicular to the working channel. The working channel inlet is arranged at one end of the working channel, and the central line of the working channel inlet is parallel to the central line of the working channel inlet, so that the instruments can conveniently enter and exit. The liquid inlet is arranged on the side face, so that the space is utilized to the maximum extent, and the smoothness of the liquid inlet is ensured.
Preferably, an eye mask is connected to one end of the lens tube main body, the eye mask is connected to the image channel, the angle between the eye mask and the image channel is 45 degrees, a prism is installed in the lens tube main body, and the image in the image channel is reflected by the prism and then is emitted out of the eye mask.
Therefore, the utility model discloses a biliary tract mirror of taking mirror sheath possesses following advantage: the structure is simple, the sheath tube and the endoscope tube are detachably connected, and the device can be detached at any time when in use, so that instantaneous pressure difference is formed inside and outside the gallbladder, thereby quickly discharging broken stones in the gallbladder along the liquid outlet channel and ensuring the operation effect.
