Description

Technical Field

[0001] This utility model relates to the field of endoscope cleaning technology, and in particular, to an endoscope channel cleaning brush. Background Technology

[0002] An endoscope is a slender tubular diagnostic and treatment device consisting of a light source, image sensor, optical lens, and mechanical components. It can enter the digestive tract, respiratory tract, abdominal cavity, and other parts of the body through natural cavities or minimally invasive incisions to observe the condition of internal tissues and organs and determine further treatment plans.

[0003] Endoscopes have channels through which instruments such as sampling forceps, snares, and foreign body nets can be inserted to the lesion site for appropriate treatment. When these instruments are withdrawn from the channels, the obtained lesion tissue often contaminates the channels. Therefore, the channels on the endoscope need to be cleaned promptly after use.

[0004] Chinese utility model patent document CN213550299U discloses a high-strength endoscope cleaning brush, including a handle, a spring outer tube, a pull cable, and a brush head. The brush head includes a main body and bristles fixed to its outer periphery. The main body is fixed to one end of the inner cavity of the spring outer tube. The pull cable is located within the inner cavity of the spring outer tube and connected to the main body. After repeated use, if the connection between the main body and the spring outer tube becomes unstable and the brush head detaches, it can be pulled out of the endoscope's clamping channel using the pull cable. The pull cable enhances the strength of the spring outer tube and facilitates movement of the brush head within the endoscope's clamping channel during cleaning. The inventors discovered that the cleaning brush described in the above-mentioned literature has the following defects when used in practice: because the front end of the spring outer tube is filled with the cable and the main body of the brush head, the front end of the spring outer tube is not easy to bend smoothly when going around bends, and thus cannot effectively guide the movement of the rear end of the spring outer tube, thereby hindering the movement of the spring outer tube. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, an endoscope channel cleaning brush that facilitates the smooth movement of the spring tube in the channel is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an endoscope channel cleaning brush, including a spring tube, a brush assembly and a handle, wherein the handle is connected to the rear end of the spring tube, and a connector is connected to the front end of the spring tube; the brush assembly includes a brush rod connected to the connector and brush bristles connected to the brush rod; a fixing member is provided inside the spring tube near the connector, the fixing member is fixedly connected to the spring tube, and an internal steel wire rope is fixedly connected between the fixing member and the handle; a deformation guide section is formed on the spring tube at the part between the connector and the fixing member.

[0007] Furthermore, the fixing member has a cylindrical structure, the fixing member and the cavity of the spring tube cooperate with each other, and the outer wall of the fixing member is fixedly connected to the spring tube.

[0008] Furthermore, a spiral groove is formed on the outer surface of the fastener, and the spring tube fits into the threaded groove.

[0009] Furthermore, the front end of the fastener is provided with an operating part.

[0010] Furthermore, a power transmission section is formed on the spring tube at the location between the fixing member and the handle, and the pitch of the deformation guide section is greater than the pitch of the power transmission section.

[0011] Furthermore, the rear end of the fastener is provided with a fixing hole, and the front end of the built-in steel wire rope is fixedly connected in the fixing hole.

[0012] Furthermore, the connector has a sleeve-shaped structure with both ends through it, the front end of the spring tube is fixedly connected to the rear end face of the connector, and the rear end of the brush rod is fixedly inserted into the connector.

[0013] Furthermore, the outer surface of the connector is provided with a conical structure, and a large end and a small end are formed on the connector. The outer diameter of the spring tube is larger than the outer diameter of the brush rod. The brush rod is fixedly inserted into the small end, and the spring tube is fixedly connected to the end face of the large end.

[0014] Furthermore, the brush assembly also includes a guide head, which is fixedly mounted on the front end of the brush handle, and the guide head has a spherical structure.

[0015] The beneficial effects of this utility model are as follows: The endoscope channel cleaning brush of this utility model has a built-in steel wire rope connected between the handle and the fixing part. This, along with the spring tube, provides sufficient power to the movement of the brush assembly when the handle is operated, thus helping to control the movement of the brush assembly. During the inward pushing of the brush assembly, especially when turning, the deformable guide section at the front end of the spring tube is not filled with the built-in steel wire rope or the brush rod, making the deformable guide section more prone to bending and deformation. This effectively guides the advancement of the spring tube, facilitating its smooth movement. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figures 1-4 This utility model provides an endoscope canal cleaning brush, including a spring tube 1, a brush assembly 2 and a handle 3. The handle 3 is connected to the rear end of the spring tube 1, and a connector 4 is connected to the front end of the spring tube 1. The brush assembly 2 includes a brush rod 21 connected to the connector 4 and brush bristles 22 connected to the brush rod 21. A fixing member 5 is provided inside the spring tube 1 near the connector 4. The fixing member 5 is fixedly connected to the spring tube 1. An internal steel wire rope 6 is fixedly connected between the fixing member 5 and the handle 3. A deformable guide section 11 is formed on the spring tube 1 at the part between the connector 4 and the fixing member 5.

[0024] This utility model discloses an endoscope channel cleaning brush. In use, medical personnel insert the front brush assembly 2 into the endoscope channel. Pushing or pulling the handle 3 moves the brush assembly 2 along the channel, and rotating the handle 3 rotates the brush assembly 2, thus cleaning the channel wall with the bristles 22. An internal steel wire rope 6 connects the handle 3 and the fixing member 5, providing sufficient power to the movement of the brush assembly 2 when the handle 3 is operated, along with the spring tube 1, aiding in controlling the movement of the brush assembly 2. During the inward pushing of the brush assembly 2, especially when turning, the deformable guide section 11 at the front end of the spring tube 1 is not filled with the internal steel wire rope 6, nor with the brush rod 21, making the deformable guide section 11 more prone to bending and deformation. This effectively guides the advancement of the spring tube 1, facilitating its smooth movement.

[0025] In this embodiment, the fixing member 5 is generally cylindrical in shape, and it mates with the cavity of the spring tube 1. The outer wall of the fixing member 5 is fixedly connected to the spring tube 1. In a preferred embodiment, the fixing member 5 and the spring tube 1 are fixedly connected by laser welding. Compared with soldering, laser welding melts metal rapidly at high temperatures, does not require flux or a soldering iron tip for auxiliary heating, has higher welding efficiency, does not produce excessive "weld scars," does not affect the external dimensions of the spring tube 1, has good appearance consistency, and avoids the risk of scratching the endoscope channel wall.

[0026] In a preferred embodiment, a spiral groove 51 is formed on the outer surface of the fastener 5. The spring tube 1 fits into the spiral groove 51, and a portion of the spring tube 1 is laser-welded to the spiral groove 51. The portion of the spring tube 1 sleeved on the fastener 5 has multiple turns, and the bottom wall of the spiral groove 51 fits into the spring tube 1, increasing the contact area between the spring tube 1 and the fastener 5, thereby improving the connection stability between the two. At the same time, the spiral groove 51 increases the difficulty for the fastener 5 to move axially relative to the spring tube 1, further ensuring that the two will not easily separate. In specific assembly, the fastener 5 can be inserted into the spring tube 1 from the front end, and then the fastener 5 can be rotated. The fastener 5 will gradually screw into the spring tube 1 along the spiral groove 51. Once the fastener 5 is in place, it can be fixed to the spring tube 1 by welding.

[0027] A power transmission section 12 is formed on the spring tube 1 between the fixing member 5 and the handle 3. The pitch of the deformable guide section 11 is greater than the pitch of the power transmission section 12. The looser spiral of the deformable guide section 11 facilitates bending deformation and serves as a guide, while the tighter spiral of the power transmission section 12 facilitates power transmission, ensuring that the power can be promptly transmitted forward to the brush assembly 2 when the medical staff operates the handle 3. The increased pitch of the deformable guide section 11 can be achieved by stretching the deformable guide section 11 after the fixing member 5 is moved into place.

[0028] Please see Figure 2 , Figure 4 In a preferred embodiment, the front end of the fixing member 5 is provided with an operating part 52, which allows the user to rotate the fixing member 5. For example, the operating part 52 is configured as a groove structure, and the user can insert a screwdriver into the groove structure and then rotate the screwdriver to drive the fixing member 5 to rotate, thereby causing the fixing member 5 to gradually screw into the spring tube 1.

[0029] Furthermore, a fixing hole 53 is provided at the rear end of the fixing member 5, and the front end of the built-in steel wire rope 6 is fixedly connected in the fixing hole 53. During installation, one end of the built-in steel wire rope 6 is first inserted into the fixing hole 53, and then the two are fixed together by laser welding. In addition, in this embodiment, the rear end of the spring tube 1 is fixedly connected to the handle 3 by adhesive bonding, and the rear end of the built-in steel wire rope 6 is fixedly connected to the handle 3 by an interference fit. Of course, the spring tube 1 and the handle 3, as well as the built-in steel wire rope 6 and the handle 3, can also be connected by welding, snap-fit, or other fixing methods as used in the prior art; this is not limited here.

[0030] The installation method of the fixing part 5 is as follows: first, fix the front end of the built-in steel wire rope 6 to the fixing part 5, then screw the fixing part 5 into the spring tube 1 from the front end of the spring tube 1, and finally fix the rear end of the spring tube 1 to the handle 3 and fix the rear end of the built-in steel wire rope 6 to the handle 3.

[0031] The handle 3 has a ring-shaped structure and is made of thermoplastic polymer material (ABS).

[0032] The connector 4 is a sleeve-shaped structure with both ends open. The front end of the spring tube 1 is fixedly connected to the rear end face of the connector 4, and the rear end of the brush rod 21 is inserted into the connector 4 and fixedly connected to the connector 4. In this embodiment, the connector 4, the spring tube 1, and the brush rod 21 are all fixedly connected by laser welding. The rear end of the brush rod 21 is fixedly inserted into the connector 4, which increases the connection strength between the brush rod 21 and the connector 4 and prevents them from easily separating. Furthermore, the outer diameter of the spring tube 1 is larger than the outer diameter of the brush rod 21, and the outer surface of the connector 4 is set as a conical structure, so that a large end and a small end are formed along the axial direction on the connector 4. The brush rod 21 is fixedly inserted into the small end, and the spring tube 1 is fixedly connected to the end face of the large end, so that the brush rod 21 and the spring tube 1 achieve a gradual transition connection, which is beneficial for the connector 4 to bend.

[0033] The brush handle 21 is made of steel wire, and the bristles 22 are made of nylon. The brush assembly 2 also includes a guide head 23, which is fixedly installed at the front end of the brush handle 21. The guide head 23 has a spherical structure and is used to guide the movement of the brush handle 21. At the same time, the spherical structure of the guide head 23 can prevent the front end of the brush handle 21 from scratching the endoscope channel wall.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
