Description

Technical Field

[0001] This utility model relates to the field of endoscope control technology, and in particular to a novel endoscope steering mechanism. Background Technology

[0002] Currently, endoscopes are widely used in medical and industrial fields. In the medical field, endoscopes are used to examine patients, such as the esophagus, small intestine, and large intestine. In the industrial field, they can be used to inspect steam turbines, generators, chemical pipelines, aerospace engines, and other equipment. When inspecting these industrial devices, endoscopes often need to bend and turn to reach the areas requiring examination.

[0003] However, the existing endoscope steering control mechanism is relatively simple, and the control mechanism cannot accurately and quickly control the steering of the endoscope, thus affecting the application effect of the endoscope. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the endoscope steering control mechanism mentioned in the background art is relatively simple and cannot accurately and quickly control the steering of the endoscope, and to propose a new type of endoscope steering mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel endoscope steering mechanism includes a base plate and an endoscope body. A base plate is fixedly connected to the top of the base plate, and multiple pivot seats are fixedly connected to the bottom of the base plate. Corresponding pivots are rotatably connected within the pivot seats. A lower fork seat is fixedly inserted into the top of the base plate, and an intermediate connecting block is rotatably connected to the top of the lower fork seat. An upper fork seat is rotatably connected to the top of the intermediate connecting block. A control lever is fixedly connected to the top of the upper fork seat, and a transmission cover is fixedly sleeved on the control lever. Four traction cables are fixedly inserted into the bottom edge of the transmission cover. One end of each traction cable passes sequentially through the top of the base plate, the pivot seats, and the side of the base plate, extending into the endoscope body. The top of the base plate has multiple mounting slots corresponding to the traction cables, and a traction bolt is fixedly sleeved at the end of each traction cable located within a mounting slot.

[0007] Preferably, the endoscope body is provided with an insertion tube and a distal bend at the end away from the base plate, and a plurality of the traction cables pass through the endoscope body and the insertion tube in sequence and extend into the distal bend.

[0008] Preferably, the intermediate connecting block is rotatably connected to the lower fork seat and the upper fork seat via a first rotating bolt and a second rotating bolt, respectively.

[0009] Preferably, a knob is fixedly sleeved on the top of the control lever.

[0010] Preferably, the pivot seat is provided with a narrow groove corresponding to the traction cable.

[0011] Preferably, the traction cable is connected to the transmission cover via a connector.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the control lever can be tilted in any direction through the universal connection mechanism, thereby pulling the corresponding traction cable. The traction cable pulls the front traction cable through the connecting bolt, thereby causing the front bending part to bend, thus achieving precise control of the endoscope.
