Detailed Description

When the existing endoscope works, the traction wire of the objective lens is flexible, the control mechanism is difficult to control the traction wire, the moving speed and the direction of the traction wire can not be adjusted as expected, and when the objective lens finds the position to be diagnosed, the traction wire of the objective lens is suspended in the cavity of the examined body and can not be fixed, so that certain inconvenience is brought to the work of the objective lens; therefore, we have designed a new endoscope to overcome the disadvantages of the prior art, and the technical solution will be described in detail below.

As shown in fig. 1-6, the technical solution is an improvement of a conventional endoscope, which mainly includes a control mechanism 1, an objective lens 3, and an objective lens traction wire 2, wherein the control mechanism 1 can control the objective lens traction wire 2 to move in a subject, such as controlling a bending angle and a bending direction, so that the objective lens 3 moves along with the objective lens traction wire 2, and thus reaches a position to be diagnosed and treated to work; however, there is a problem in that the objective lens drawing wire 2 is operated, and since it is flexible, the control mechanism 1 is difficult to control its direction, so that a structure is required to control the objective lens drawing wire 2 so that its moving amplitude is not so large, which will be described in detail below: the technical scheme also comprises a positioning sheath 4, the objective lens traction wire 2 is arranged on the inner side of the positioning sheath 4, the objective lens 3 is arranged at the end part of the objective lens traction wire 2 to facilitate observation, and the other side of the positioning sheath 4 is connected with the control mechanism 1; when the positioning sheath 4 is added, the control mechanism 1 controls the objective traction wire 2 to move, the working amplitude of the objective traction wire 2 is not large, the control mechanism 1 can conveniently control the direction and the angle of the objective traction wire 2, so that the working efficiency can be further accelerated, and the objective traction wire 2 can be used by people conveniently, wherein in order to better move the objective traction wire 2 according to needs, the end part and the side surface of one side of the positioning sheath 4, which is far away from the control mechanism 1, are provided with openings 41, when the objective traction wire 2 works, an objective 3 on the objective traction wire 2 is firstly positioned at the opening 41 at the end part of the positioning sheath 4 and is in a horizontal state with the whole positioning sheath 4, the objective 3 firstly finds an approximate position to be diagnosed when entering a detected body, if the position to be diagnosed is in the side direction of the positioning sheath 4, the control mechanism 1 controls the objective traction wire 2 to move backwards, and then controls the bending direction of the objective traction wire, the technical scheme has the advantages of wider application, convenient operation and less rigid use until the position to be diagnosed is found.

Although the positioning sheath 4 can solve the problem that the movement amplitude of the objective lens traction wire 2 is too large, when the endoscope works, the positioning sheath 4 cannot move as required, which brings certain inconvenience to the objective lens 3 to find a position to be diagnosed, therefore, in order to move the positioning sheath 4 like the objective lens traction wire 2, a positioning sheath traction wire 5 is designed on the positioning sheath 4, the positioning sheath traction wire 5 is fixedly installed in the positioning sheath 4, the positioning sheath 4 can move along with the movement of the positioning sheath traction wire 5, a moving mechanism 6 is further arranged on the positioning sheath traction wire 5, and the moving mechanism 6 can control the positioning sheath traction wire 5 to move in a detected body, such as the control of a bending angle and a bending direction; the working principle of the moving mechanism 6 for controlling the movement of the positioning sheath drawing wire 5 is similar to the working principle of the control mechanism 1 for controlling the movement of the objective drawing wire 2.

When the structure works, because the moving speeds of the objective lens traction wire 2 and the positioning sheath 4 are not consistent, the objective lens traction wire 2 may be too fast to slip out of the positioning sheath 4, and further the control mechanism 1 is difficult to operate the objective lens traction wire and the positioning sheath 4 is troublesome to find out the position to be diagnosed, so that a sheath pipe joint component is arranged between the control mechanism 1 and the moving mechanism 6 to link the objective lens traction wire 2 and the positioning sheath 4, so that the objective lens traction wire 2 and the positioning sheath 4 can be linked, and the objective lens traction wire and the positioning sheath can be conveniently used by people; the sheath pipe joint component comprises a sheath pipe joint 71, a sheath pipe connecting sleeve 72 and a locking ring 73; one end of the sheath tube joint 71 is provided with a locking ring 73, the other end of the sheath tube joint is provided with a sheath tube connecting sleeve 72, one end of the control mechanism 1, which is connected with the objective lens traction wire 2, is accommodated in the locking ring 73 and is in snap-fit connection with the locking ring 73, and the positioning sheath 4 is fixedly arranged on one side of the sheath tube connecting sleeve 72, which is far away from the locking ring 73, wherein the locking ring 73, the sheath tube joint 71, the sheath tube connecting sleeve 72 and the positioning sheath 4 are communicated with each other, and during operation, the objective lens traction wire 2 respectively penetrates through the sheath tube joint 71, the sheath tube connecting; the moving mechanism 6 is arranged on one side of the sheath pipe joint 71; when the positioning sheath traction wire 5 works, the positioning sheath traction wire respectively penetrates through the sheath pipe joint 71, the sheath pipe connecting sleeve 72 and the positioning sheath 4 and is respectively fixedly connected with the sheath pipe joint 71, the sheath pipe connecting sleeve 72 and the positioning sheath 4; the working principle of linkage of the objective lens traction wire 2 and the positioning sheath traction wire 5 is as follows: firstly, the control mechanism 1 can control the objective lens traction wire 2 to move among the sheath pipe joint 71, the sheath pipe connecting sleeve 72 and the positioning sheath 4, the moving mechanism 6 controls the positioning sheath traction wire 5 to move, and then the sheath pipe joint 71, the sheath pipe connecting sleeve 72 and the positioning sheath 4 move simultaneously, namely the positioning sheath traction wire 5 can drive the objective lens traction wire 2 to move when moving, and further linkage is realized, so that the objective lens traction wire 2 cannot move and is separated from the positioning sheath 4 quickly; furthermore, in normal operation, in order to protect the objective lens, the objective lens is always accommodated in the positioning sheath when the objective lens does not reach the position in the subject to be specifically diagnosed, but because the objective lens is suspended, which may slip out of the positioning sheath, the objective lens traction wire 2 is further provided with an objective lens balloon 9 at the end close to the objective lens 3, the objective lens balloon 9 operates on the same principle as the single balloon 81 described above, at the time of normal entry into the subject, the objective lens balloon 9 is inflated at this time, so that the objective lens 3 can be stably fixed in the positioning sheath 4, and after reaching the relative position, abandoning the balloon 9 of the objective lens, controlling the traction wire 2 of the objective lens to lead the objective lens 3 to extend out of the positioning sheath 4, thereby carrying out accurate position finding, then, the objective lens balloon 9 is inflated to be fixed in the cavity of the detected body, so that the objective lens 3 can work subsequently.

After the objective lens 3 is found to be in a proper position, the objective lens 3 needs to be kept stable, but at this time, because the positioning sheath 4 is in a suspended state and cannot be kept fixed, a balloon is designed on the positioning sheath 4 for solving the problem, the balloon comprises a single balloon 81, an air inlet 721 is arranged above the sheath tube connecting sleeve 72, the air inlet 721 is externally connected with an air pump (not shown), the inside of the balloon is connected with the single balloon 81 through a pipeline, and when the objective lens 3 needs to be kept fixed, the air pump works to inflate the single balloon 81; when the single balloon 81 works, the single balloon 81 is in a semi-cylindrical shape, wherein the single balloon 81 is inflated to enable the inclination amplitude of the positioning sheath 4 to be larger, so that the objective lens 3 can be further close to a diagnosis and treatment position; although the single balloon 81 can play a role in fixing, the single balloon is only semi-fixed, and one side of the positioning sheath 4 cannot be fixed, so that the double balloon 82 is further arranged on the positioning sheath 4, the working principle of the double balloon 82 is the same as that of the single balloon 81, but the single balloon 81 and the double balloon 82 do not affect each other in working, namely, the single balloon 81 and the double balloon 82 can work simultaneously and independently, during working, the double balloon 82 is cylindrical, the double balloon 82 can be completely attached to a cavity channel of a detected body, so that the positioning sheath 4 can be completely fixed, in order to enable the fixing effect to be better, the single balloon 81 and the double balloon 82 are arranged, the working of each balloon does not affect each other, and people can conveniently inflate and deflate the designated balloon according to needs without affecting the use of other balloons.
