Problems solved by technology

[0003] Traditional endoscopes generally control their bending and steering through scissor handles and steering wires. The operation accuracy is not high, the control of the steering angle is not accurate enough, and the viewing angle is small. Due to the technical bottleneck caused by the size of the pipe and the blind angle, Bring hidden dangers to the safety of surgery

Embodiment 1

[0031] Embodiment 1: This embodiment provides a bendable steering endoscope, see figure 1 with figure 2 , which includes a catheter part, a steering handle for controlling the bending of the catheter and a pipe connector, the catheter part includes a hard tube 1 and a flexible tube 2 made of plastic, and the hard tube 1 is sleeved on the outside of the flexible tube 2.

[0032] see image 3 , Figure 11 , the steering handle includes a handle cover 3 and a handle body cover 4, the handle cover and the handle body cover are both cylindrical in shape, the handle cover is placed outside the handle body cover, and a shaft is arranged between the handle cover and the handle body cover Guide rails and sliders. The guide rail is a strip chute 6 axially arranged on the outer surface of the handle body cover, the slider is a limit bolt 5 arranged in the screw hole of the side wall of the handle cover, and the bolt 5 matches with the chute 6 .

Embodiment 2

[0043] Example 2: see Figure 7 with Figure 8 , The structure of this embodiment is basically the same as that of Embodiment 1, except that a balloon 19 for preventing backflow of liquid in the cavity and a water injection channel opening 21 of the hard tube are also provided on the outer wall of the hard tube. The balloon 19 is connected with the inflation nozzle 20 through an inflation conduit positioned on the outer wall of the hard tube. When in use, the balloon is not inflated first, and then the balloon is inflated after being inserted into the cavity. The hard tube water injection channel opening 21 is used for injecting water into the cavity through the hard tube 1 .

Embodiment 3

[0044] Embodiment 3: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the outer tube 1 is a guide tube, the inner tube 2 is an elbow tube, one end of the elbow tube is curved, and the other end is It is connected with an interface of the pipeline connector 8 and fixed at the interface, and a guide wire or optical fiber can pass through the elbow tube. The guide wire 22 is made of stainless steel, and the diameter of the guide wire 2 is within the range of 0.015 mm to 0.35 mm. The outer end of the elbow pipe is curved, and the material used for the curved end of the elbow pipe can be softer than the material used for the rest of the pipe. The guide tube is made of polypropylene.

[0045] The outer wall of the guide tube is also provided with a balloon 19 for preventing backflow of liquid in the cavity, and a hard tube water injection channel opening 21 . The balloon 19 is connected with the inflation nozzle 20 through the ...

Abstract

The invention relates to a combined type soft or hard endoscope. The endoscope comprises a catheter part, a steering handle for controlling the catheter to bend and a pipeline connector, wherein the catheter part comprises an outer catheter and an inner catheter, and the outer catheter is sleeved outside the inner catheter. The combined type soft or hard endoscope is characterized in that: the steering handle comprises a handle sleeve and a handle body cover; the handle sleeve is sleeved outside the handle body cover; an axial guide rail and a sliding block are arranged between the handle sleeve and the handle body cover; the guide rail and the sliding block are respectively fixed on the handle sleeve or the handle body cover; the outer catheter is fixedly connected with the handle sleeve; the inner catheter passes through a through hole in the handle sleeve, and is connected with an interface of the pipeline connector and is fixed to the interface; the pipeline connector is positioned in the handle body cover and is fixedly connected with the handle body cover; and other interfaces of the pipeline connector are respectively connected with each channel opening on the handle body cover. The combined type soft or hard endoscope has the characteristics of simple structure, convenient operation and flexible steering, and can be used for tubal endoscopes, ureteroscopes and endoscopes in other departments.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a combined soft and hard endoscope. Background technique [0002] At present, there are separate flexible ureteroscopes and rigid ureteroscopes in the world. Rigid ureteroscopes are easy to operate and can pass through the ureter to reach the renal pelvis. However, since the front end of the rigid ureteroscope cannot be bent, it cannot adjust its direction after entering the renal pelvis to enter each group of renal calices for various diagnosis and treatment; although the front end of the flexible ureteroscope can be unidirectional Or bend and turn at a large angle, but it is difficult to enter the renal pelvis and renal calyces through the ureter. Although it can enter the renal pelvis and renal calyces under the guidance of X-rays, X-rays are more harmful to doctors and patients. Developing a flexible and rigid ureteroscope has always been the common goal of ureteroscope ma...
