Technical Field

The utility model relates to the field of medical equipment, it is a extrusion formula steel wire adjusting device who is applied to in the endoscope to and endoscope.

Background

An endoscope is a common modern medical apparatus, as shown in fig. 4, and comprises an endoscope handle, a guide tube 4 is connected to the endoscope handle, one end of the guide tube 4 provided with a head cap 41 can be bent, and the end of the guide tube 4 can bend the end of the guide tube 4 to a specific angle under the action of tensile force. When the endoscope is used, a doctor inserts the catheter 4 into a human body, and the orientation of the end part of the catheter 4 needs to be adjusted by the doctor through the adjusting device 5 on the handle of the endoscope due to the fact that the structure of an in-vivo channel such as a urethra or an intestinal tract of the human body is complex.

In the prior art, the steel wire 2 is arranged in the endoscope handle, the two ends of the steel wire 2 are respectively connected with the head end cap 41 and the adjusting device 5, and the adjusting device is controlled to pull the head end cap to be bent, so that the end part of one side, provided with the head end cap, of the catheter is bent to a specific angle.

Because the endoscope is small in overall volume, the diameter of the steel wire used for drawing the end part of the guide pipe to bend in the endoscope is small. Moreover, when the endoscope is used, the orientation of the end part of the catheter needs to be adjusted repeatedly, so that the change frequency of the tensile force applied to the steel wire is high, and the problem that the steel wire is deformed and loosened after being used for multiple times can occur. The endoscope is a precise medical instrument, and often needs a doctor to operate and control according to the use experience, and once the steel wire has the problem of deformation, the operation precision of the endoscope changes, and the operation hand feeling of the endoscope also changes, so that the doctor is difficult to adapt in a short time.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the steel wire used for adjusting the orientation of the guide pipe in the endoscope is easy to deform after being used for a long time, and the deformed steel wire can influence the operation accuracy of the endoscope and the diagnosis efficiency.

In order to solve the technical problem, the utility model provides a technical scheme as follows:

the utility model provides an endoscope steel wire adjusting device includes at least: a base; the steel wire fixing pieces are in threaded connection with the two ends of the base respectively, and steel wire fixing holes are formed in the steel wire fixing pieces.

Preferably, the steel wire mounting includes handle and screw thread post, the screw thread post with base threaded connection, the handle with screw thread post fixed connection, just the handle is located the outside of base, the steel wire fixed orifices is located on the handle.

Further, the handle is circular.

Preferably, the base is provided with lightening holes.

The utility model also provides an endoscope, at least including the endoscope shell, as above arbitrary one endoscope steel wire adjusting device and steel wire, endoscope steel wire adjusting device is fixed to be located in the endoscope shell, the steel wire with steel wire fixed orifices fixed connection.

When the endoscope is used, the two steel wires are respectively connected with the steel wire fixing pieces at the two ends, the steel wire fixing pieces are twisted to adjust the extending length of the steel wire fixing pieces relative to the base, the tension degree of the steel wires can be adjusted, the loosened steel wires after deformation recover to be in a tight state, and the influence on the operation accuracy of the endoscope after the steel wires are pulled and deformed is avoided. And the adoption threaded connection can make the length adjustment of steel wire more level and smooth, prevents that the steel wire is too tight.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, a fixed connection, an integral connection, or a detachable connection; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention in specific situations.

A preferred embodiment of the endoscope steel wire adjusting device is shown in fig. 1 and fig. 2, and at least includes a base 1, two ends of the base 1 are respectively connected with a steel wire fixing member 12 through threads, a steel wire fixing hole 11 is formed on the steel wire fixing member 12, and the end portion steel wire fixing hole 11 of the steel wire 2 is fixedly connected, specifically, the steel wire 2 can be fixed by bonding, welding or directly passing through the steel wire fixing hole 11 and then knotting. When the steel wire 2 is tensioned and deformed, the steel wire fixing piece 12 is twisted to adjust the tension degree of the steel wire 2, so that the steel wire 2 is restored to be in a tight state, and the problem that the operation precision of the endoscope is reduced is solved.
