[0007] The utility model provides an endoscope with a replaceable instrument channel, which is characterized in that it comprises a working channel port, an eyepiece, a handpiece, a terminal, an adapter and a working channel, the working channel port is fixedly connected to the handpiece, the bottom of the handpiece is connected to the terminal, the terminal is movably connected to the adapter, the adapter is fixedly connected to the working channel, an adapter groove is arranged inside the adapter, a lock hole is arranged on the upper surface of one side of the adapter, a positioning hole is arranged directly below the lock hole, through holes are respectively arranged on the upper and lower sides of one side of the terminal, a spring is fixedly installed in each of the through holes, the other side of the spring located on the upper side of the terminal is fixedly connected to the press lock buckle, and the other side of the spring located on the lower side of the terminal is fixedly connected to the positioning buckle.

[0008] An eyepiece is arranged on one side of the handheld piece.

[0009] One side of the positioning buckle fixedly connected to the spring is a flat surface, and the other side of the positioning buckle is a convex arc surface.

[0010] The side of the push lock buckle fixedly connected to the spring is a cylinder, and the other side surface of the push lock buckle is a convex arc surface.

[0011] The beneficial effects of the utility model are as follows: the utility model is an endoscope with a replaceable instrument channel, by arranging a spring in the end head, the spring is respectively connected to a press lock buckle and a positioning buckle, and by arranging an adapter, corresponding through holes are arranged at corresponding positions of the adapter, when the working channel is installed, it is directly installed by pressing and rotating, and by changing the installation method of threaded screwing to a press and rotate method, the installation method is simpler and more convenient, which is convenient for the staff to timely replace different working channels during the operation, saving time, improving the replacement efficiency, and thus speeding up the operation process.

[0019] Example 1

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0021] like Figure 1As shown, the utility model provides a replaceable instrument channel endoscope, which is characterized in that it includes a working channel port 1, an eyepiece 2, a handpiece 3, a terminal 4, an adapter 6 and a working channel 7, the working channel port 1 is fixedly connected to the handpiece 3, the bottom of the handpiece 3 is connected to the terminal 4, the terminal 4 is movably connected to the adapter 6, the adapter 6 is fixedly connected to the working channel 7, an adapter groove 63 is arranged inside the adapter 6, a lock hole 61 is arranged on the upper surface of one side of the adapter 6, a positioning hole 62 is arranged directly below the lock hole 61, through holes are respectively arranged on the upper and lower sides of one side of the terminal 4, a spring 43 is fixedly installed in each through hole, the other side of the spring 43 located on the upper side of the terminal 4 is fixedly connected to the press lock buckle 41, and the other side of the spring 43 located on the lower side of the terminal 4 is fixedly connected to the positioning buckle 42.

[0022] like Figure 1 As shown, the eyepiece 2 is arranged on one side of the handpiece 6 .

[0023] like Figure 5 As shown, one side of the positioning buckle 42 fixedly connected to the spring 43 is a flat surface, and the other side of the positioning buckle 42 is a convex arc surface.

[0024] like Figure 5 As shown, one side of the push lock buckle 41 fixedly connected to the spring 43 is a cylinder, and the other side surface of the push lock buckle 41 is a convex arc surface.

[0025] Example 2

[0026] When the utility model is in use: when the instrument channel 1 needs to be replaced, the push lock buckle 41 is pressed by an external tool so that the push lock buckle 41 is pressed back into the inside of the through hole. Then, the hand-held adapter 6 is inserted into the end head. When the adapter 6 is inserted, since one side of the positioning buckle 42 at the lower part of the end head 4 is a convex arc surface and contacts the surface of the end head 4, when the adapter 6 is inserted into the end head 4 from bottom to top, the inner surface of the adapter 6 will automatically squeeze the positioning buckle 42, and the positioning buckle 42 will be automatically pressed into the corresponding through hole. Therefore, the positioning buckle 42 does not need to be pressed by an external tool. When the inner surface of the adapter 6 contacts the surface of the push lock buckle 41, the external tool can be released. At this time, the push lock buckle 41 is automatically pressed by the inner surface of the adapter 6.

[0027] Then, the adapter 6 is rotated, and when the positioning buckle 42 is automatically popped out of the positioning hole 62 on the lower side of the adapter 6, the pressing lock buckle 41 is also automatically popped out, and the adapter 6 is fixed.

[0028] After the replacement is completed, the working channel 7 can be inserted into the human body and observation can be performed through the eyepiece 2.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
