Description

Technical Field

[0001] This utility model relates to an electronic endoscope. Background Technology

[0002] In the field of medical electronic endoscopy, such as bronchoscopes, ureteroscopes, otolaryngoscopes, cholangioscopes, duodenoscopes, and gastroscopes, image data of the body inside the subject is acquired through an image sensor inserted at the tip of the endoscope. This data is then transmitted to an image processor for image processing, and finally displayed on a screen for the operator to view. The subject can be human or animal. The body inside the subject typically refers to the internal organs, such as the lungs, kidneys, bladder, stomach, and intestines. The operator is primarily a physician.

[0003] During endoscopic examinations or surgeries, a traction rope is typically controlled by an operating handle to bend and deform the tip of the insertion tube, adjusting its angle to facilitate easier entry into the natural passages of organs. This angle adjustment also allows for the detection of images at different locations. The traction rope is usually embedded inside a Bowden wire spring tube, with one end fixed to the operating lever on the handle and the other end fixed to the insertion point of the insertion tube, resulting in limited operational flexibility.

[0004] Current electronic endoscopes can generally be adjusted in four directions, namely forward, backward, left and right. They require two sets of control mechanisms. Each set of control mechanisms includes a traction rope control mechanism and a locking control mechanism. The traction rope control mechanism and the locking control mechanism are two independent and unrelated sets, which leads to a complex structure, a large number of parts, complicated assembly, and a larger handle. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic endoscope that solves the technical problem that in the existing electronic endoscope, the traction rope control mechanism and the locking control mechanism are two independent and unrelated sets, resulting in a complex structure, a large number of parts, complicated assembly, and a large handle.

[0006] The technical solution of this utility model is implemented as follows:

[0007] An electronic endoscope includes an insertion part and a handle. The insertion part is installed at one end of the handle and includes a sleeve, a beam guide, and a lens. The lens is installed at the front end of the sleeve. The handle is characterized by having a left control mechanism and a right control mechanism on its left and right sides respectively. The left control mechanism controls the bending of the front end of the insertion part in the front-back direction, and the right control mechanism controls the bending of the front end of the insertion part in the left-right direction. The left and right control mechanisms have the same structure, including a direction rod, a direction rod shaft, a brake rod, a brake rod shaft, a face cover, a direction rod fixing bracket, a first brake disc, a second brake disc, a traction rope fixing disc, a traction rope cover, and a traction rope.

[0008] The handle has a mounting hole on each side, with the steering rod fixing bracket nested inside the mounting hole. A cover is installed on the outside of the steering rod fixing bracket. The steering rod is installed on the outer end of the steering rod shaft, and the brake rod is installed on the outer end of the brake rod shaft. The steering rod shaft is fitted into the first center hole of the brake rod shaft and passes through the second center hole in the middle of the steering rod fixing bracket. The first brake disc, the second brake disc, the traction rope fixing disc, and the traction rope cover are located inside the handle. The traction rope is wound on the traction rope fixing disc and fitted with the traction rope cover. The traction rope fixing disc is fitted into the inner end of the steering rod shaft. The first brake disc and the second brake disc are fitted onto the outside of the steering rod shaft in sequence. One side of the first brake disc is connected to the inner end of the brake rod shaft. The second brake disc is located between the first brake disc and the traction rope fixing disc. The traction rope cover and the second brake disc are located on both sides of the traction rope fixing disc, respectively.

[0009] The first brake disc has several inclined first protrusions spaced circumferentially on its end face facing the traction rope fixing disc, and the second brake disc has several inclined second protrusions spaced circumferentially on its end face facing the first brake disc. The first and second protrusions cooperate with each other. By rotating the brake lever, the brake lever shaft and the first brake disc rotate, causing the first and second protrusions to be relatively misaligned. This pushes the second brake disc closer to or away from the end face of the traction rope fixing disc, thereby adjusting the tension of the traction rope fixing disc.

[0010] The outer end of the aforementioned steering rod shaft is connected to the steering rod via screws.

[0011] The two ends of the traction rope wound on each of the aforementioned traction rope fixing reels extend into the tube sleeve from the end opening of the handle.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. The handle of this utility model is provided with a left control mechanism and a right control mechanism on the left and right sides respectively. The left control mechanism controls the bending of the front end of the insertion part in the front-back direction, and the right control mechanism controls the bending of the front end of the insertion part in the left-right direction. The left and right control mechanisms have the same structure, including a direction rod, a direction rod shaft, a brake rod, a brake rod shaft, a cover, a direction rod fixing bracket, a first brake disc, a second brake disc, a traction rope fixing disc, a traction rope cover, and a traction rope. The direction rod, direction rod shaft, brake rod, brake rod shaft, cover, direction rod fixing bracket, first brake disc, second brake disc, traction rope fixing disc, traction rope cover, and traction rope are combined together to form an integrated control structure, which simplifies the structure, reduces the number of parts, facilitates assembly, makes the structure compact, and reduces the size of the handle.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] like Figures 1 to 9 As shown, this embodiment provides an electronic endoscope, including an insertion part 1 and a handle 2. The insertion part 1 is installed at one end of the handle 2. The insertion part 1 includes a sleeve 11, a beam guide 13, and a lens 12. The lens 12 is installed at the front end of the sleeve 11. The handle 2 is characterized by having a left control mechanism 3 and a right control mechanism 4 respectively on its left and right sides. The left control mechanism 3 controls the bending of the front end of the insertion part 1 in the front-back direction, and the right control mechanism 4 controls the bending of the front end of the insertion part 1 in the left-right direction. The left control mechanism 3 and the right control mechanism 4 have the same structure, including a direction rod 31, a direction rod pivot 32, a brake rod 33, a brake rod pivot 34, a face cover 35, a direction rod fixing bracket 36, a first brake disc 37, a second brake disc 38, a traction rope fixing disc 39, a traction rope cover 30, and a traction rope 41.

[0027] The handle 2 has a mounting hole 20 on each side, positioned opposite each other. The steering rod fixing bracket 36 is nested in the mounting hole 20. A cover 35 is installed on the outside of the steering rod fixing bracket 36. The steering rod 31 is installed on the outer end of the steering rod shaft 32, and the brake rod 33 is installed on the outer end of the brake rod shaft 34. The steering rod shaft 32 is fitted into the first center hole 340 of the brake rod shaft 34 and passes through the second center hole 360 ​​in the middle of the steering rod fixing bracket 36. A first brake disc 37, a second brake disc 38, and a traction rope fixing disc 39 are also provided. The traction rope cover 30 is located inside the handle 2. The traction rope 41 is wound around the traction rope fixing disc 39 and the traction rope cover 30 is fitted on the outside. The traction rope fixing disc 39 is fitted on the inner end of the steering rod shaft 32. The first brake disc 37 and the second brake disc 38 are fitted on the outside of the steering rod shaft 32 in sequence. One side of the first brake disc 37 is installed and connected to the inner end of the brake rod shaft 34. The second brake disc 38 is located between the first brake disc 37 and the traction rope fixing disc 39. The traction rope cover 30 and the second brake disc 38 are located on both sides of the traction rope fixing disc 39, respectively.

[0028] The first brake disc 37 has several inclined first protrusions 371 spaced circumferentially on its end face facing the traction rope fixing disc 39, and the second brake disc 38 has several inclined second protrusions 381 spaced circumferentially on its end face facing the first brake disc 37. The first protrusions 371 and the second protrusions 381 cooperate with each other. By rotating the brake lever 33, the brake lever shaft 34 and the first brake disc 37 are rotated, causing the first protrusions 371 and the second protrusions 381 to be relatively misaligned. This pushes the second brake disc 38 closer to or away from the end face of the traction rope fixing disc 39, thereby adjusting the tension of the traction rope fixing disc 39.

[0029] The outer end of the aforementioned steering rod shaft 32 is connected to the steering rod 31 by screws 42.

[0030] The two ends of the traction rope 41 wound on each of the aforementioned traction rope fixing discs 39 extend into the sleeve 11 from the end opening of the handle 2.

[0031] This utility model effectively combines the steering rod 31, steering rod shaft 32, brake rod 33, brake rod shaft 34, face cover 35, steering rod fixing bracket 36, first brake disc 37, second brake disc 38, traction rope fixing disc 39, traction rope cover 30, and traction rope 41, so that the traction rope control mechanism and locking control mechanism are integrated into one, with high integration, compact structure, simplified structure, reduced number of parts, easy assembly, and smaller handle size.

[0032] The working patent of this utility model: Medical staff grab the direction rod 31 and rotate it, thereby causing the direction rod shaft 32 and the traction rope fixing plate 39 to rotate. The traction rope fixing plate 39 pulls the traction rope 41, and the traction rope 41 causes the front end of the insertion part 1 to bend in the front-back direction or in the left-right direction.

[0033] In addition, medical staff grasp the brake lever 33 and rotate it, so that the brake lever shaft 34 and the first brake disc 37 rotate synchronously. By utilizing the relative misalignment between the first protrusion 371 on the first brake disc 37 and the second protrusion 381 on the second brake disc 38, the second brake disc 38 is pushed towards or away from the end face of the traction rope fixing disc 39, thereby adjusting the tightness of the traction rope fixing disc 39.

[0034] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
