Endoscope tube end bending control structure

The end-end bending control structure of the endoscope tube is mainly provided with an axial through groove inside the duct for the control piece to be accommodated therebetween, the duct is composed of different softness parts, and can be controlled by The movement of the piece reaches the purpose of controlling the end of the catheter to bend at a certain angle or to maintain a straight shape.

It is known that the function of the endoscope is to examine or perform medical behavior with minimal invasiveness to the human body. Therefore, the structure includes a long tube that can be inserted into the body cavity, and is provided at the end of the catheter. With the lens module and the illumination structure, the image of the image is obtained by photography. However, in order to obtain more complete data, one-way photography is insufficient, so the conventional design uses the connecting line to extend to the end of the catheter, and borrows Due to the rotation of the rotating mechanism of the handle end, the connecting line is pulled to control the bending of the tail end of the catheter. As shown in FIGS. 1 and 2, the conventional structure mainly uses a plurality of unit bodies (1), and the coupling body (12) is provided on the cylindrical body (11) by combining the unit pieces (1) (12). And the cylindrical body (11) of the other unit body (1) is pivotally connected to the two unit body by the micro rivets (13), or is riveted by using the laser welding, although the result of the pivoting is obtained, but the process It is quite complicated and difficult, and each catheter requires a combination of several unit bodies, and then the combination of the connecting wires is used to pull the unit bodies, so that it is obviously inconvenient in manufacturing and assembly, and it is quite troublesome in operation. Another known laparoscopic or hysteroscopic structure is designed to have a curved angle at the end of the catheter. Folded fixed structure, but this has an endoscope tube with a bent end, except that it is inconvenient when inserted into the human body. During operation, the operator must always swing the catheter with his hand to observe the part he wants to see, but the action will Causes the patient to be quite uncomfortable and not practical.

The present invention is a bending control structure for the end of the endoscope catheter. The catheter is composed of tubes of different hardness and hardness, and the tail end portion has at least one section which is elastically bendable, and the other part is a hard material. The support portion is formed with an axial through groove inside the conduit for the control piece to be accommodated therebetween. The tail end of the control piece is provided with an elastic portion having a tendency to bend toward one side, and the other end extends to the inside of the handle. And a toothed strip is combined with a gear set at the handle. When the gear set is rotated at the handle, the toothed strip and the control piece can be linked, and when the elastic portion of the control piece is moved to the bendable portion of the catheter The bending portion can be swung to one side to achieve the effect of bending the outer end of the catheter. When the control piece moves toward the end of the handle, the elastic portion is separated from the bendable portion, and the bendable portion is Under the support of the non-guided elastic push-up, the return and the support portion are in a straight state, and the purpose of controlling the bending of the tail end of the catheter is achieved. Accordingly, the creation of the catheter can be maintained as a straight flat shape to facilitate its insertion into the body cavity of the human body, and then the angle of the catheter end can be changed in a simple manner to provide an easy view of the interior of the cavity to be observed. And will not cause the patient's discomfort, and achieve the improvement of efficacy.

Referring to Figures 3 and 4, the present invention is constructed as an embodiment of an endoscope tube bending end control structure. The tube (2) is composed of tubes of different hardness and hardness, and the tail end portion is at least An elastic bendable portion (21) made of a soft plastic material is provided, and the remaining portion is a support portion (22) formed of a hard material, and an axial through groove is formed inside the conduit (2). (23), for the control piece (3) to be accommodated therebetween, the control piece (3) is obtained by quenching with a steel sheet, and has excellent elasticity, so that the tail end is formed to have a tendency to bend toward one side. The elastic portion (31) extends to the inside of the handle (4) and is combined with a toothed strip (32), and the handle (4) is provided with a gear set (41) for rotating at the handle (4) In the gear set (41), the toothed strip (32) and the control piece (3) can be interlocked, and the elastic portion (31) of the control piece (3) is restrained inside the catheter (2), so that it is not bent. When it moves to the bendable portion (21) of the conduit (2), under the high elastic force, the bendable portion (21) can be driven to swing to one side, as shown in FIG. The effect of bending the end of the conduit (2) When the control piece (3) moves toward the end of the handle (4), the elastic portion (31) leaves the bendable portion (21) of the catheter (2), and the bendable portion (21) is in the non-guided elastic force. Under the ejector support, the return and support portion (22) is in a straight state as shown in FIG. When the end of the catheter (2) is to have a larger bending angle, as long as the control piece (3) is moved further toward the tail end, as shown in Fig. 5, under the greater elastic force of the elastic portion (31) , can have a larger bending angle. In addition, under the linkage of the gear set (41), the creation can obtain different bending angle positions, and provide Excellent practical effect.

However, as described above, it is only a preferred embodiment of the present invention. The creation may also be provided with a plurality of bendable portions (21) at the end portion of the conduit (2) to form and support the tail end. The bendable portion (21) of the portion (22) continuously spaced, as shown in Figs. 6 and 7, causes the elastic portion (31) of the control piece (3) to be sequentially moved to a bendable state when the present application is applied. In the part (21), the bendable portion (21) can be pushed and pushed, and the tail end of the duct (2) is curved in the same direction to form an arc shape, and the photographing angle of nearly 270 degrees is obtained, and the best is obtained. Efficacy.

Please refer to FIG. 8 and FIG. 9 again. In the implementation, the two control pieces (3) and (3') can be arranged in the through groove (23) of the conduit (2) to match the two sets of toothed strips (32). ), (32') and gear sets (41), (41') are in the device, and another set of control pieces (3'), toothed strips (32'), and gear sets (41) may be utilized. The operation of ') bends the tail end of the catheter (2) toward the other side, providing a comprehensive photographic function of both upper and lower angles, which is beneficial to the observation and progress of the medical staff during the operation.

In summary, this creation can control the angle of the endoscope catheter by simple operation, so that the catheter can be maintained as a whole straight shape, so as to facilitate its penetration into the body cavity of the human body, and then simple The operation mode is to change the tail end of the catheter and the photographic lens module disposed at the end to obtain the best shooting effect at different angles, and the position adjustment of the gear set can be utilized, and the specific ones can be randomly positioned. Angle, providing easy for the operator to view the internal position of the cavity to be observed, and will not cause discomfort to the patient. For the improvement of the quality of the operation, it is inexplicable, so the creation has met the requirements of the new patent, and the application is made according to law. And please give it as soon as possible.
