Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an insertion part rotating assembly and an endoscope. Background Technology

[0002] An endoscope is a commonly used medical device that allows direct access to human cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope typically includes: an insertion part for insertion into the body, a handle for operation, and a display device for visualizing the internal environment of the body's natural cavities. Through the coordination of these three parts, the endoscope enables visualization of the human body's interior, exploration of lesions, and treatment.

[0003] As is known in the prior art, an endoscope comprises an operating section and an insertion section, wherein the operating section is a handle, and the insertion section is mounted on the operating section. The distal end of the endoscope insertion section is an active bending section. A traction rope is installed inside the handle, with its distal end connected to the active bending section and its proximal end wound around a dial. By moving a lever, the traction rope can move synchronously in opposite directions, thereby bending the active bending section of the insertion section. The distal end of the active bending section is equipped with a camera module, a light source device, and an instrument channel. After the insertion section is inserted into the human body, the direction of the camera module is adjusted by bending the active bending section, allowing the camera module to be aimed at the lesion site to provide diagnostic information to the doctor.

[0004] Traditional endoscopes have active bending sections with two bending directions. To more precisely adjust the orientation of the distal components, existing technologies have developed active bending sections with four bending directions, thus providing more directional options. Specifically, these technologies incorporate two traction mechanisms within the handle: one mechanism controls the vertical bending of the active bending section, while the other controls its horizontal bending.

[0005] The applicant has discovered that the existing technology has at least the following technical problems: When using an endoscope in the prior art, if the insertion part needs to be rotated, it is often achieved by the doctor twisting their arm. This operation is inconvenient for surgery and observation, and is generally inconvenient to use. When the doctor twists their arm to rotate the insertion part, the traction rope twists and undergoes significant deformation. This deformation reduces the service life of the traction rope and also reduces the precision control of the bending of the insertion part. Utility Model Content

[0006] The purpose of this utility model is to provide an insertion part rotation component and an endoscope to solve the technical problem that the insertion part of the endoscope in the prior art requires the doctor to twist his arm to achieve the insertion, which is inconvenient to operate and affects the efficiency of the operation. The various technical effects of the preferred technical solution among the many technical solutions provided by this utility model are described in detail below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The insertion part rotating assembly provided by this utility model includes an insertion part and a rotating shaft part, wherein:

[0009] The insertion part is used to extend into the patient's body for the user to observe the lesion. The rotating shaft is rotatably connected to the housing. The insertion part passes through the rotating shaft and is fixedly connected to the rotating shaft.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] This utility model provides an insertion part rotation component and endoscope, which gets rid of the predicament of traditional electronic endoscopes that rely on doctors to twist their arms to rotate the insertion part, which makes it impossible to perform surgery accurately or affect observation. It greatly facilitates the surgical operation and observation of electronic endoscope operators.

[0034] The following is combined Figures 1-5 The technical solution provided by this utility model will be described in more detail.

[0035] Example 1:

[0036] The present invention provides an insertion part rotation assembly, including a housing 6, an insertion part 61 and a rotating shaft 2, wherein: the insertion part 61 is used to extend into the patient's body for the user to observe the lesion; the rotating shaft 2 is rotatably connected to the housing 6; the insertion part 61 passes through the rotating shaft 2 and is fixedly connected to the rotating shaft 2; the rotating shaft 2 can rotate left and right relative to the housing 6 together with the insertion part 61 under the action of external force.

[0037] The distal end of the insertion section 61 is an active bending section. A traction rope is installed inside the handle, with its distal end connected to the active bending section and its proximal end wound around a dial. By moving a lever, the traction rope can move synchronously in opposite directions, thereby bending the active bending section of the insertion section 61. The distal end of the active bending section of the insertion section 61 is equipped with a camera module, a light source, and an instrument channel. After the insertion section 61 is inserted into the human body, the bending of the active bending section adjusts the direction of the camera module, allowing it to be aimed at the lesion site to provide diagnostic information to the doctor. (The above structure of the insertion section 61 is a conventional structure of endoscopes in the prior art.)

[0038] In this embodiment, the insertion part rotating assembly allows the rotating shaft 2 to be manually rotated, which in turn drives the insertion part 61 to rotate left and right relative to the endoscope housing 6. Without affecting the normal function of the insertion tube, the insertion part 61 can rotate around its axis. This eliminates the predicament of traditional electronic endoscopes where doctors have to twist their arms to rotate the insertion part 61, which can lead to inaccurate surgery or affect observation. This greatly facilitates the surgical operation and observation of electronic endoscope operators.

[0039] As an optional implementation, see Figure 4 As shown, a locking block 22 is provided inside the rotating shaft part 2. (See Figure 2) Figure 5 As shown, a fixing block 62 is fixed to one end of the housing 6 facing the rotating shaft 2. When the locking block 22 abuts against the fixing block 62, it is used to limit the rotation angle of the rotating shaft 2.

[0040] The locking block 22 and the fixing block 62 cooperate to form a limiting structure, which can limit the rotation angle of the rotating shaft 2, making it more convenient to use and preventing the rotating shaft 2 from rotating too much.

[0041] For details, see Figure 4 As shown, there are two locking blocks 22, and the angle formed between the two locking blocks 22 and the central axis of the rotating shaft 2 is 190°. The fixing block 62 is located between the two locking blocks 22 and is used to restrict the rotating shaft 2 from rotating to the left or right at a maximum angle of 90°.

[0042] When the rotating shaft 2 is rotated to the left or right, different locking blocks 22 can abut against the fixing block 62, thereby limiting the maximum angle of rotation of the rotating shaft 2 to the left to 90° and the maximum angle of rotation of the rotating shaft 2 to the right to 90°.

[0043] As an optional implementation, see Figure 2 As shown, a raised rib 21 is provided on the outer peripheral wall of the rotating shaft part 2. The raised rib 21 is used to increase the friction between the user's hand and the rotating shaft part 2, making it easier to rotate the rotating shaft part 2. The raised rib 21 can also be a groove or the like.

[0044] In the existing technology, the traction rope is twisted and deformed by the way the doctor rotates the endoscope with his wrist. This deformation can reduce the service life of the traction rope and also reduce the bending precision control of the insertion part 61.

[0045] To prevent the traction rope from twisting when the rotating shaft 2 rotates, as an optional implementation, see [link to implementation details]. Figure 1 and Figure 2 As shown, the rotating shaft 2 is fixedly connected to the directional block 4. The directional block 4 is provided with a first directional opening 41 and a second directional opening 42. There is a gap between the first directional opening 41 and the second directional opening 42. The first directional opening 41 and the second directional opening 42 are used to fix different traction ropes.

[0046] The rotating shaft 2 and the limiting block 4 are fixed together by means of snap-fit ​​or other means. When the rotating shaft 2 rotates, it drives the limiting block 4 to rotate synchronously. The first limiting port 41 and the second limiting port 42 are used to fix different traction ropes, thereby overcoming the twisting of the traction rope when the insertion part 61 of the endoscope rotates, preventing the deformation of the traction rope, extending the service life of the traction rope, and ensuring the smooth progress of endoscopic surgery.

[0047] As an optional implementation, see Figure 3 As shown, the directional block 4 is located inside the housing 6. (See attached image) Figure 4 As shown, the directional block 4 is provided with a central hole 43 that passes through both ends of the directional block 4. The insertion part 61 passes through the central hole 43. The first directional opening 41 and the second directional opening 42 are located on opposite sides of the central hole 43. The directional block 4 does not affect the direction of the insertion part 61.

[0048] As an optional implementation, see Figure 1 As shown, the insertion part rotating assembly also includes a silicone protective sleeve 3, which is fixedly connected to the rotating shaft 2, and the insertion part 61 passes through the silicone protective sleeve 3. The outer diameter of the silicone protective sleeve 3 gradually tapers away from the rotating shaft 2. The silicone protective sleeve 3 serves to protect the insertion part 61, and the above-described structure of the silicone protective sleeve 3 reduces its size.

[0049] As an optional implementation, see Figure 2 and Figure 3 As shown, the insertion part rotation assembly also includes a clamping block 5, which is fixedly connected to the rotating shaft part 2 and there is a gap between them. The housing 6 is provided with an insertion part 61, which extends into the gap. The clamping block 5 is located in the housing 6. The rotating shaft part 2 and the clamping block 5 can rotate relative to the housing 6 under the action of external force.

[0050] The above structure can restrict the axial movement between the housing 6 and the rotating shaft 2, that is, it ensures that the rotating shaft 2 and the clamping block 5 can rotate relative to the housing 6 under the action of external force, and the rotation is carried out around the axis of the rotating shaft 2. At the same time, it can prevent the rotating shaft 2 from separating from the housing 6, thus improving the stability of the structure.

[0051] Example 2:

[0052] This embodiment provides an endoscope, including a housing 6 and the aforementioned insertion part rotation assembly. The housing 6 and the rotating shaft 2 are capable of rotating relative to each other around the axis of the rotating shaft 2. This eliminates the predicament of traditional electronic endoscopes where the surgeon has to twist their arm to rotate the insertion part 61, which can lead to inaccurate surgery or affect observation. This greatly facilitates the surgical operation and observation of the electronic endoscope operator.
