Description

An endoscope comprising a control body having a bent structure

[0001] One aspect of the present invention relates to an endoscope including a control body having a bent structure, and more particularly, to an endoscope including a control body arranged so that a power transmission system performs its function smoothly under the bent structure.

[0002] The material described in this section merely provides background information on embodiments of the present invention and does not constitute prior art.

[0003] An endoscope is a device used to look inside the body, usually for medical purposes.

[0004] Refers to a medical device. Depending on the area being examined, an endoscope is called a "bronchoscope," "gastroscope," "laparoscope," or "colonoscope." Unlike most other medical imaging devices, it is a medical device that is inserted directly into the body to take pictures of the organs inside the body.

[0005] Endoscopy has been developed with the rapid advancement of optical technology and electronics, including the development of optical fibers.

[0006] Thanks to this advancement, electronic endoscopy has become a significant advancement in the field of gastroenterology. The development of electronic endoscopy has enabled not only diagnostic endoscopy, which allows direct observation of the patient's internal organs and histological examinations, but also the rapid development of various therapeutic endoscopy techniques, replacing open surgery.

[0007] The endoscope generally consists of an insertion tube that is inserted into the patient with a bending section and a flexible portion, a control body that is connected to one end of the insertion tube and controls the bending motion of the bending section, a connector that is connected to a light source device, and a control body.

[0008] It may include a universal code that separates the body and connector.

[0009] The endoscope is used to control the bending motion of the bending section.

[0010] A mechanical string is installed between the roller bodies, and the mechanical string is connected to a control knob installed on the control body. An endoscope with this structure can perform a bending motion of the bending section by transmitting power to the mechanical string when the user, a physician, manually operates the control knob.

[0011] Meanwhile, the mechanical string, a component of the endoscope, is formed in bundles and extends through the endoscope's insertion tube, control body, and universal cord. This structure inevitably bends as the medical user uses the endoscope. However, the mechanical string is crucial for smoothly transmitting power, and if it bends, its internal forward and backward movement becomes difficult, potentially hindering power transmission.

[0012] If the mechanical string has a problem transmitting power, it becomes difficult to accurately collect image information about the target area, which is a problem.

[0013] These issues are particularly serious when the control body of an endoscope is designed to bend up to 90 degrees. In particular, the development of a new internal structure that ensures smooth power transmission in endoscopes with bendable mechanical strings is urgent.

[0014] The background technology described above is technical information that the inventor possessed for the purpose of deriving embodiments of the present invention or acquired during the derivation process, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the filing of the embodiments of the present invention.

However, the present invention is not limited to the embodiments presented below, but may be implemented in various different forms, and it should be understood that it includes all transformations, equivalents, and substitutes included in the spirit and technical scope of the present invention.

[0049] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are assigned the same drawing numbers and redundant descriptions thereof are omitted.

[0050] FIG. 1 shows a control body (10) of an endoscope according to one embodiment of the present invention, and FIG. 2 shows a plurality of power transmission cables (120) having a twisted structure (130) by a first cable holder (100) and a second cable holder (150) inside the control body (10) of FIG. 1.

[0051] Figure 1 also shows a user holding the control body (10).

[0052] An endoscope according to one embodiment of the present invention comprises: a universal cord (20) connected to a power-supplying connector (30); an insertion tube (40) including a bending section (50) inserted into a body cavity and bent up, down, left, and right;

[0053] It may be configured to include at least one of a control body (10) having one end connected to the universal code (20) and the other end connected to the insertion tube (40); and a plurality of power transmission cables (120) that transmit power received from the connector (30) to the bending section (50).

[0054] A plurality of power transmission cables (120) may have a structure in which one end is connected to a bending section (50) and the other end is connected to a connector (30). The connector (30) may be connected to an external device such as a power supply device, a light source device, or an image processing device to receive power. The power transmission cable (120) may be configured to sequentially connect to a connector (30), a universal code (20), a control body (10), a flexible portion, and a bending section (50).

[0055] A plurality of power transmission cables (120) can receive power from a connector (30) and transmit the received power to a bending section (50), and the bending section (50) can receive the power and perform a bending motion in an up-down direction or a left-right direction.

[0056] In this embodiment, the power transmission cable (120) may be configured to include a coil spring and a mechanical string that moves back and forth within the coil spring. The coil spring may form a passage that allows the mechanical string to move back and forth.

[0057] The mechanical string is connected to the power transmission system of the connector (30) on one side, so that the connector (30) can transmit power provided from an external device such as a light source device to the bending section (50).

[0058] The power transmission cables (120) can generally be composed of four, and the four power transmission cables (120) can have a structure in which two of them are coupled. For example, the plurality of power transmission cables (120) can be composed of a first cable (C1), a second cable (C2), a third cable (C3), and a fourth cable (C4), wherein the first cable (C1) and the third cable (C3) are coupled in a structure in which when the first cable (C1) advances, the third cable (C3) advances, and when the first cable (C1) advances, the third cable (C3) advances, and when the second cable (C1) advances, the fourth cable (C4) advances.

[0059] The connector (30) may have a structure in which the first cable (C1) and the second cable (C3) are coupled by a first shaft that fixes the first sprocket, and the second cable (C2) and the fourth cable (C4) are coupled by a second shaft that fixes the second sprocket. The first cable (C1) and the third cable (C3) may be responsible for the up-and-down bending motion of the bending section (50), and the second cable (C2) and the fourth cable (C4) may be responsible for the left-right bending motion of the bending section (50).

[0060] According to an embodiment, inside the control body (10) or connector, a plurality of power transmission cables (120) may have at least one twisted structure (130).

[0061] In the case where the endoscope is provided with a plurality of power transmission cables (120) that pass through one end and the other end of the control body (10), and the one end and the other end of the control body (10) are not positioned in a straight line but are facing in different directions, by forming at least one twist structure (130) in the plurality of power transmission cables (120) that pass through the one end and the other end, even if the plurality of power transmission cables (120) are bent inside the control body (10), a smooth reciprocating motion is possible without backlash.

[0062] If a twisted structure (130) is not formed in a structure in which power transmission cables (120) are arranged in bundles as in one embodiment of the present invention, when the bundle of power transmission cables (120) is bent, some of the power transmission cables (120) are excessively stretched and other parts of the power transmission cables (120) are excessively compressed, so that the mechanical string inside the coil spring cannot smoothly move forward and backward, and this may result in inaccurate bending operation of the bending section (50).

[0063] In one embodiment of the present invention, when a twisted structure (130) is formed in a bundle of power transmission cables (120) inside a control body (10) of an endoscope, and one end and the other end of the control body (10) have a structure in which they face different directions, even if the bundle of power transmission cables (120) is bent inside the control body (10), a smooth power transmission function without backlash can be performed.

[0064] The conventional technology has a structure in which a bundle of power transmission cables (120) arranged inside a control body (10) with one end and the other end facing different directions is bent by employing a configuration such as a roller or a pulley, but according to one embodiment of the present invention, by forming a slight twist structure (130) in the bundle of power transmission cables (120), the bundle of power transmission cables (120) can be naturally bent on its own. In addition, the present invention can eliminate unnecessary installation space created when employing a configuration such as a roller or a pulley inside the control body (10) by employing the twist structure (130) inside the control body (10).

[0065] The configuration of a control body (10) of an endoscope according to one embodiment of the present invention is described.

[0066] The control body (10) according to the present embodiment may have a structure in which a first cable holder (100) and a second cable holder (150) are installed in a frame portion (160). The frame portion (160) may be configured to include a first frame (110) and a second frame (140). According to the embodiment, the first cable holder (100) may be installed in the first frame (110), and the second cable holder (150) may be installed in the second frame (140). Here, the frame portion (160) may be configured to serve as a skeleton of the control body (10) within the control body (10), and the first frame (110) may be configured to have a universal code (20) connected to an end thereof, and the second frame (140) may be configured to have an insertion tube (40) connected to an end thereof.

[0067] The first cable holder (100) can serve to secure a bundle of power transmission cables (120) extending toward the universal code (20), and the second cable holder (150) can serve to secure a bundle of power transmission cables (120) extending toward the insertion tube (40). That is, the first cable holder (100) and the second cable holder (150) can serve to secure a coil spring of the power transmission cable (120). Here, the mechanical string can move forward and backward inside the secured coil spring.

[0068] Specifically, four coil springs can be fixed to the upper and lower ends of the first cable holder (100), and four coil springs can be fixed to the upper and lower ends of the second cable holder (150).

[0069] The first frame (110) may be configured to extend at an angle of approximately 90 degrees (°) from the second frame (140). The first frame (110) may include a portion that passes over the edge (c) of the index finger (b) of the left hand when a user, such as a doctor using an endoscope, holds the control body (10) portion with the left hand. The second frame (140) may include a portion that the user using an endoscope holds with the left hand. The user may position the first frame (110) to pass over the edge (c) of the hand connected to the index finger (b) and hold the second frame (140) to assume a basic posture for holding the endoscope.

[0070] According to one embodiment of the present invention, the control body (10) may include a first cable holder (100) that fixes a plurality of power transmission cables (120) in a first direction (A) and a second cable holder (150) that fixes a plurality of power transmission cables (120) in a second direction (B) different from the first direction (A), and a twisting structure (130) of the plurality of power transmission cables (120) may be formed between the first cable holder (100) and the second cable holder (150).

[0071] According to an embodiment, a twisted structure (130) of a plurality of power transmission cables (120) according to the present invention can be formed by a first cable holder (100) and a second cable holder (150) twisting and fixing a plurality of power transmission cables (120). That is, while the first cable holder (100) fixes a bundle of power transmission cables (120) on one side, the second cable holder (150) twists and fixes the bundle of power transmission cables (120) on the other side, thereby forming a twisted structure (130) of a bundle of power transmission cables (120) between the first cable holder (100) and the second cable holder (150).

[0072] FIG. 3 shows the structure of a first cable holder (100) according to one embodiment of the present invention, and FIG. 4 shows the structure of a second cable holder (150) according to one embodiment of the present invention.

[0073] In addition, in relation to the bending section in FIG. 1, the upper, lower, left, and right of the medical image collected by the endoscope in the basic posture in which the user is holding the control body (10) corresponds to the upper, lower, left, and right of the bending section (50).

[0074] According to one embodiment of the present invention, a plurality of power transmission cables (120) may be configured to include a first coupled first cable set and a second coupled second cable set. Here, the first cable set may refer to the first cable (C1) and the third cable (C3) in the above-described embodiment, and the second cable set may refer to the second cable (C2) and the fourth cable (C4).

[0075] According to an embodiment, a first cable set including a first cable (C1) and a third cable (C3) and a second cable set including a second cable (C2) and a fourth cable (C4) may be arranged in parallel in the first cable holder (100), and the first cable set and the second cable set may be arranged in a diagonal shape in the second cable holder (150).

[0076] The first cable holder (100) can serve to secure a bundle of power transmission cables (120) connected to a connector (30), and the second cable holder (150) can serve to secure a bundle of power transmission cables (120) connected to a bending section (50).

[0077] In the case where the first axis of the connector (30) transmits power to perform the up-and-down bending motion of the bending section (50), and the second axis transmits power to perform the left-right bending motion of the bending section (50), this structure has a configuration of a first cable (C1) and a third cable (C3) that are connected and coupled to the first axis of the connector (30), and a configuration of a second cable (C2) and a fourth cable (C4) that are connected and coupled to the second axis of the connector (30), so that the first cable (C1) and the third cable (C3) connected from the connector (30) can be fixed while extending without twisting and passing through the upper right (r) and the lower right (s) of the first cable holder (100), and the second cable (C2) and the fourth cable (C4) connected from the connector (30) can also be fixed while extending without twisting and passing through the upper right (p) and the lower right (q) of the first cable holder (100). That is, the first cable set and the second cable set can have a structure in which they are arranged in parallel.

[0078] By arranging each pair of coupled cables in parallel in the first cable holder (100), the four mechanical strings connected to the connector (30) can be fixed to the first cable holder (100) of the control body (10) without twisting.

[0079] Meanwhile, since the bending section (50) has a structure in which the mechanical strings coupled to the upper and lower sides of the bending section (50), that is, the first cable (C1) and the third cable (C3), are connected in order to bend up and down, and the mechanical strings coupled to the left and right sides of the bending section (50), that is, the second cable (C2) and the fourth cable (C4), are connected in order to bend left and right,

[0080] The second cable holder (150) can be fixed so that the first cable (C1) and the third cable (C3) are arranged in a diagonal shape and the second cable (C2) and the fourth cable (C4) are arranged in a diagonal shape, similar to the arrangement of the four mechanical strings including the first cable (C1), the second cable (C2), the second cable (C4) and the fourth cable (C4) of the bending section (50).

[0081] By arranging each pair of coupled cables in a diagonal shape in the second cable holder (150), the four mechanical strings connected to the bending section (50) can be fixed to the second cable holder (150) of the control body (10) without being twisted.

[0082] According to this embodiment, the first cable holder (100) can arrange the first cable set and the second cable set in parallel, and the second cable holder (150) can arrange the first cable set and the second cable set in a diagonal shape, so that both the first cable set and the second cable set have a twisted structure (130).

[0083] According to an embodiment, the first cable holder (100) may form a plurality of fitting portions (170) on its inner surface into which a plurality of power transmission cables (120) are inserted and installed. The configuration of the fitting portions (170) will be described later.

[0084] In addition, according to an embodiment, the second cable holder (150) includes a base (153), a center block (152), and a cover block (151), and the base (153) and the center block (152) can fix one pair of the plurality of power transmission cables (120), and the center block (152) and the cover block (151) can fix another pair of the plurality of power transmission cables (120). The base (153), the center block (152), and the cover block (151) can each be bolt-joined.

[0085] Figure 5 shows the appearance of a cable support (180) according to one embodiment of the present invention.

[0086] FIG. 6 shows a view in which a power transmission cable (120) and other structures are partitioned by a frame portion (160) inside a control body (10) of an endoscope according to one embodiment of the present invention.

[0087] According to an embodiment, a frame portion (160) may be included in which a first cable holder (100) and a second cable holder (150) are installed. Here, the frame portion (160) may include one or more cable holders (180) that mutually isolate each of a plurality of power transmission cables (120) and allow the plurality of power transmission cables (120) to be bent and arranged.

[0088] The cable holder (180) may be formed with a cable contact surface that suppresses the sliding of a plurality of power transmission cables (120) in a specific direction. When the mechanical string is pulled by the motor, a bundle of power transmission cables (120) positioned between the first cable holder (100) and the second cable holder (150) may be pulled together. In the present invention, in order to minimize the pulling of the power transmission cables (120), at least one cable holder (180) having a cable contact surface formed in a radial direction may be installed to suppress the sliding of the power transmission cables (120).

[0089] That is, the role of the cable holder (180) is to perform the first function of mutually isolating multiple power transmission cables (120) by erecting a wall (cable contact surface) to prevent coil springs from being twisted even in a structure where the power transmission cables (120) can be twisted, and to perform the second function of establishing a path so that the power transmission cables (120) can pass by bending between the first cable holder (100) and the second cable holder (150).

[0090] That is, when the mechanical string is pulled by the motor, a force is applied in a specific direction, so a wall is erected in all directions where the force is applied.

[0091] Meanwhile, the frame portion (160) may have a first surface (E) and a second surface (F). The control body (10) may be partitioned so that a plurality of power transmission cables (120) pass through the first surface (E) and a structure other than the plurality of power transmission cables (120) pass through the second surface (F). Here, the structure other than the plurality of power transmission cables (120) may include an air tube, a water tube, a light guide, a video signal cable, etc. The endoscope according to the present invention can suppress backlash of the power transmission cables (120) by allowing a bundle of power transmission cables (120) to pass while being spaced apart from other structures.

[0092] The central portion (U) of the first cable holder (100) is a space through which the image sensor and various tubes pass. Therefore, to secure this space and secure four coil springs, a narrow groove structure is formed to form a fitting portion (170) structure that prevents the cables from being pulled out after they are inserted. This is a structure through which structures such as light fibers, air tubes, and water tubes all pass through the space of the central portion (U). These structures enter the interior of the first frame (110) connected to the second frame (140) and pass along the second surface (F) of the second frame (140) as they pass downward. In addition, the power transmission cables (120) passing through the fitting portion (170) formed on the edge of the first frame (110) pass along the first surface (E) of the second frame (140). Accordingly, a structure is formed in which the water tube, air tube, and other structures passing along the second surface (F) and the power transmission cable (120) passing along the first surface (E) are separated.

[0093] The present invention has the effect of preventing backlash and ensuring precise power transmission by adopting a structure in which the power transmission cable (120) is arranged separately.

[0094] The use of the term "above" and similar referential terms in the specification of the present invention (especially in the claims) may refer to both singular and plural. Furthermore, when a range is described in the present invention, it is intended that the invention encompasses inventions that apply individual values ​​falling within the range (unless otherwise stated), and is equivalent to describing each individual value constituting the range in the detailed description of the invention.

[0095] Unless the steps constituting the method according to the present invention are explicitly described in a specific order or are not described to the contrary, the steps may be performed in any appropriate order. The present invention is not necessarily limited to the order in which the steps are described. The use of all examples or exemplary terms (e.g., "for example," etc.) in the present invention is merely intended to illustrate the present invention in detail, and the scope of the present invention is not limited by the examples or exemplary terms unless otherwise defined by the claims. Furthermore, those skilled in the art will appreciate that various modifications, combinations, and variations can be configured according to design conditions and factors within the scope of the appended claims or their equivalents.
