Description

Soft and hard wire transfer structure of endoscope

The invention relates to a wire transfer structure, in particular to a soft and hard wire transfer structure of an endoscope.

The use of endoscopes is quite extensive and is suitable for use in medically relevant applications, in locations or environments where workers cannot reach, such as internal pipelines, internal engines, heat exchangers, and When the endoscope operation is related to the inspection operation. Generally, an endoscope that is inspected by a pipeline is connected to a flexible sleeve at the front end of the hard wire, and then a lens is disposed at the front end of the sleeve, and the image data intercepted by the flexible lens passing through the sleeve is transmitted to the hard line. Return to the display for the staff to view the image.

In the process of using the endoscope, the user drives the flexible wire through the hard wire to allow the endoscope to extend into or out of the area to be inspected. Because of this, the hard wire and the soft wire are easily blocked by the foreign object during the use of the endoscope. When the external force pulls apart, the relationship between the soft wire and the hard wire electrical connection is destroyed and the endoscope is damaged. Therefore, it is necessary to design a transfer structure between the hard wire and the soft wire for the above situation, thereby reducing the chance of separation between the hard wire and the soft wire.

The main object of the present invention is to provide a soft-hard wire transfer structure for an endoscope, which can resist the pulling of hard wires and cords by external forces and reduce the chance of separation of hard wires and soft wires.

In order to achieve the foregoing object, a soft-hard wire transfer structure of an endoscope according to the present invention is connected to a hard wire, a cord and a sleeve, and the adapter structure comprises: a first half shell, Having a first chamber and a first through hole, the first through hole communicating with the first chamber; a second half housing having a second chamber and a second through hole, the second through The hole is in communication with the second chamber; the second half-shell is in abutment with the first half-shell, and the first chamber and the second chamber together form a chamber; a circuit board is disposed at the The hard wire has one end passing through the first through hole, connecting the first half case and electrically connecting the circuit board; the flexible wire is one end passing through the second through hole and electrically connected to the circuit a plate; and the sleeve is sleeved outside the flexible wire and connected to the second partial casing.

Therefore, the soft-hard wire switching structure of the endoscope provided by the present invention can be connected to the first half-shell by the second half-shell, so that the hard wire and the flexible wire connected thereto can resist the external force for the hard wire. And the pulling of the cord, reducing the chance of separation between the hard wire and the cord.

In order to explain the structure and features of the present invention in detail, the following preferred embodiments will be described with reference to the following drawings: Referring to the first to second figures, the internal view provided by the first embodiment of the present invention The mirror hard and soft wire transfer structure is connected with a hard wire 61, a flexible wire 71 and a sleeve 81. The adapter structure mainly comprises: a first partial housing 11, a second partial housing 12 and a Circuit board 13.

The first housing half 11 has a first chamber 111 and a first through hole 112. The first through hole 112 is in communication with the first chamber 111.

The second housing half 12 has a second chamber 121 and a second through hole 122. The second through hole 122 communicates with the second chamber 121. The second half-shell 12 is in abutment with the first half-shell 11 , and the first chamber 111 and the second chamber 121 together form a chamber 14 .

The circuit board 13 is disposed in the chamber 14.

The hard wire 61 is connected to the first half hole 11 and electrically connected to the circuit board 13 through one end of the first through hole 112.

The flexible wire 71 is electrically connected to the circuit board 13 through one end of the second through hole 122.

The sleeve 81 is sleeved outside the flexible wire 71 and connected to the second partial housing 12.

As shown in the third figure, it is worth mentioning that in the embodiment, the first half-shell 11 and the second half-shell 12 are semi-spherical, and when the first half-shell 11 and the After the second half-shell 12 is butted, it has a spherical shape. In addition, the capacitor 14 can be filled with a glue 15 to prevent moisture from intruding, and the second half-shell 12 cooperates with the circuit board 13 to have a recess 113 on the inner side of the edge, and the circuit board 13 is attached to the embedded In the slot 113.

Thereby, when the hard wire 61 and the flexible wire 71 are pulled by an external force, an external force is transmitted to the first partial housing 11 and the second partial housing 12, respectively, by the first partial housing 11 and The second partial housing 12 is received. Since the strength of the first half-shell 11 and the second half-shell 12 is greater than the hard wire 61 directly connecting the flexible wire 71, the hard wire 61 and the flexible wire 71 can resist external force against the hard wire 61 and the Pulling the cord 71, reducing the hard line 61 The opportunity to separate from the cord 71.

Referring to the fourth embodiment, a second embodiment of the present invention is introduced, which is different from the first embodiment in that the hard wire 61 is sleeved with a ring body 16, and the first half shell is locked by the ring body 16. Body 11. When the hard wire 61 is pulled by an external force by the arrangement of the ring body 16, the first half casing 11 is chucked through the ring body 16.

Referring to FIG. 5 to FIG. 7 , a third embodiment of the present invention is described. The difference between the first embodiment and the second embodiment lies in a wire 17 that penetrates the flexible wire 71 and is connected to the second wire. The half casing 12 and the cord 71 maintain the length of the cord 71. In this way, by the arrangement of the wire 17, the length of the cord 71 can be maintained, and when the cord 71 is pulled by an external force, the external force acting on the cord 71 can be directly transmitted to the second housing half 12 in a timely manner. The chance of the cord 71 being separated from the second partial housing 12 is reduced.

In addition to the above manner, one end of the wire 17 may be connected to a fixing block 18, and the second half-shell 12 has a fixing groove 124. The fixing block 18 is inserted into the fixing groove 124 to fix the second partial housing 12 , and the flexible wire 71 is transmitted to the second partial housing 12 .

Finally, please refer to the eighth embodiment, the fourth embodiment of the present invention is different from the foregoing first embodiment, the second embodiment and the third embodiment in that the second half-shell 12 is also capable of A shoulder 123 protrudes from the second through hole 122. When the sleeve 81 is wound by a steel wire, one end thereof is screwed into the side of the shoulder portion 123, and the shoulder portion 123 is chucked to achieve the effect that the sleeve 81 is connected to the second half-shell 12.
