Detailed Implementation

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. The content of the utility model will be further explained below in conjunction with the drawings:

[0026] Example 1

[0027] See attached document Figure 1 A medical lumen instrument cleaning device includes an electric handle 1 and multiple brushes 2.

[0028] See attached document Figure 2 The electric handle 1 includes a handle housing 11, a motor, a battery, a charging interface, a rotating shaft 12, and a controller 13.

[0029] The motor and battery are located inside the handle housing 11. The battery is a rechargeable battery used to power the motor. The charging interface is located at the rear end of the handle housing 11 and is connected to the battery via a wire for connecting a power cord to charge the battery. The controller 13 is located on the surface of the handle housing 11 and is connected to the wire between the motor and the battery. It includes a switch button and a speed control button. The switch button is used to control the opening and closing of the motor, and the speed control button is used to adjust the speed of the motor.

[0030] The rear end of the rotating shaft 12 is fixedly connected to the output shaft of the motor. The rotation of the output shaft drives the rotating shaft 12 to rotate synchronously, and the front end extends out of the front end of the handle housing 11. (See attached diagram) Figure 2 The rotating shaft 12 is a D-shaped shaft, including a flat surface 121, and a snap-fit ​​groove 122 is provided in the middle of the flat surface 121.

[0031] In another embodiment, the pivot 12 is a prism pivot (such as a quadrangular prism pivot, a pentagonal prism pivot, etc.), and a snap-fit ​​groove 122 is provided in the middle of one of the flat surfaces 121 of the prism pivot. Although the accompanying drawings only show the case where the pivot 12 is a D-shaped pivot, the case where the pivot 12 is a prism pivot can be inferred from the case of a D-shaped pivot, so it will not be described in detail.

[0032] See attached document Figure 1 , 34. The brush 2 includes a brush head 21, an extension rod 22, and bristles 23. The brush head 21 is fixedly installed at the rear end of the extension rod 22, and the front end of the extension rod 22 is rounded. When the brush 2 is pushed and pulled back and forth along the lumen of the instrument, the front end of the extension rod 22 can prevent damage to the lumen wall to a certain extent. The extension rod 22 is a flexible steel wire, which can not only provide good support for the bristles 23, but also follow the bending changes of the instrument when facing a curved lumen, so as to better clean the lumen of the instrument. When pulled out of the instrument, it can return to its initial state.

[0033] Multiple layers of bristles 23 (e.g., 10cm or 5cm in length, i.e., the surface of the 10cm or 5cm length extension rod 22 is provided with bristles 23) are fixedly connected to the surface of the extension rod 22 at a predetermined length, and each layer of bristles 23 is arranged in a spiral shape. The multiple brushes 2 equipped with the medical lumen instrument cleaning device in this patent are different, specifically in that: the length of the extension rod 22 is different (to be applicable to lumen instruments of different lengths), and / or, the length of a single bristle 23 is different (i.e., the outer diameter of the part of the extension rod 22 where the bristles 23 are provided is inconsistent, to be applicable to lumen instruments of different inner diameters), and / or, the length of the part of the extension rod 22 where the bristles 23 are provided is inconsistent (same as above, e.g., 10cm or 5cm in length, i.e., the surface of the 10cm or 5cm length extension rod 22 is provided with bristles 23).

[0034] The brush head 21 includes a brush head shell 211 and an elastic inner sleeve 212. The brush head shell 211 is hollow inside and has an open rear end face. The extension rod 22 is fixedly connected to the front end of the brush head shell 211. The elastic inner sleeve 212 is fixedly fitted inside the cavity of the brush head shell 211. A connecting cavity 2121 matching the outer contour of the rotating shaft 12 is opened along the center of the elastic inner sleeve 212 (when the rotating shaft 12 is a D-shaped shaft, the connecting cavity 2121 is the corresponding D-shaped cavity; when the rotating shaft 12 is a prism shaft, the connecting cavity 2121 is the corresponding prism-shaped cavity). The outer diameter of the rotating shaft 12 is greater than or equal to the inner diameter of the connecting cavity 2121, so that the rotating shaft 12 and the elastic inner sleeve 212 can be in close contact. A snap-fit ​​protrusion 2122 matching the position and contour of the snap-fit ​​groove 122 is provided in the middle of the connecting cavity 2121.

[0035] The inner sleeve 212 can be made of elastic materials such as nitrile rubber, silicone, and EPDM rubber. The D-shaped or prismatic shaft structure effectively prevents relative rotation between the rotating shaft 12 and the inner sleeve 212. Simultaneously, after the rotating shaft 12 is inserted into the connecting cavity 2121, the inner sleeve 212 wraps around and holds the rotating shaft 12 with its elasticity. Furthermore, the snap-fit ​​protrusion 2122 enters the snap-fit ​​groove 122, effectively preventing relative displacement between the rotating shaft 12 and the inner sleeve 212, ensuring the stability of the connection between the rotating shaft 12 and the inner sleeve 212. When the brush 2 needs to be removed, simply pull the brush 2 outwards, thus achieving a detachable and fixed connection between the brush head 21 and the rotating shaft 12.

[0036] When the motor drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the brush 2 to rotate, and the brush bristles 23 brush the inner wall of the lumen instrument.

[0037] In another embodiment of this invention, to improve the lumen cleaning effect of the lumen instrument, a vibrator is installed inside the handle housing 11. A rechargeable battery is used, and the battery is connected to the vibrator via a wire to power the vibrator. A vibration button is also provided on the controller 13, connected to the wire between the battery and the vibrator. The vibration button is used to control the opening and closing of the vibrator and / or adjust the vibration frequency of the vibrator. The vibrator emits high-frequency vibrations to drive the brush 2 to vibrate at a high frequency.

[0038] By combining the high-frequency vibration and rotation of the brush 2, the mechanical cleaning power can be enhanced, thereby improving the cleaning ability and effect of the brush 2.

[0039] Example 2

[0040] Since the medical lumen instrument cleaning device contains many components (electric handle 1 and multiple brushes 2), in order to facilitate storage and quick selection of brushes 2 of appropriate specifications, this embodiment provides a support frame 3 that can vertically suspend multiple brushes and the electric handle.

[0041] See attached document Figure 5 The support frame 3 includes a vertically mounted mounting plate 31 and a support plate 32. A mounting through hole 311 is provided at each of the left and right ends of the mounting plate 31. The support frame 3 can be fixedly installed on the side wall or wall of the operating table by passing screws, bolts, buckles, etc. through the mounting through hole 311.

[0042] Multiple parallel, equidistant strip-shaped slots 321 are formed perpendicular to the length of the support plate 32. The outer ends of the strip-shaped slots 321 extend beyond the edge of the support plate 32, and the inner ends are located in the middle of the support plate 32. The width of the strip-shaped slots 321 is greater than the outer diameter of the extension rod 22 and smaller than the outer diameter of the brush head 21. When storing the brush 2, the bristle 23 ends are vertically downward, and the extension rod 22 is moved horizontally through the strip-shaped slots 321 to the middle of the support plate 32, so that the bottom surface of the brush head 21 contacts the top surface of the support plate 32, thus vertically suspending the brush 2 on the support plate 32.

[0043] To prevent the brush 2 from slipping off the support plate 32, a limiting groove 322 is provided on the top surface of the support plate 32 and at the inner end of the strip groove 321. The depth of the limiting groove 322 is less than the thickness of the support plate 32, and the diameter is greater than the outer diameter of the brush head 21. When the bottom surface of the brush head 21 contacts the top surface of the support plate 32, the bottom surface of the brush head 21 enters the limiting groove 322, and a step is formed on the surface of the support plate 32, which can prevent the brush 2 from slipping off the support plate 32.

[0044] To remove the brush 2, simply lift the brush 2 up so that the bottom surface of the brush head 21 is disengaged from the limiting groove 322, and then move the brush 2 horizontally outward along the strip groove 321 to remove the brush 2 from the support plate 32.

[0045] In order to store the electric handle 1 on the support plate 32, a hanging rope 14 is connected to the rear end of the handle housing 11, and a hanging plate 323 is provided at both ends of the support plate 32. The outer diameter of the inner end of the hanging plate 323 is smaller than the outer diameter of the outer end, so that the hanging rope 14 can be hung on the hanging plate 323, so that the electric handle 1 can be vertically suspended on the support plate 32 by the hanging rope 14.

[0046] See attached document Figure 6 A real-life photo showing multiple brushes and electric handles vertically suspended on support frame 3.

[0047] The method of using the medical lumen instrument cleaning device in this patent is as follows: First, select a brush 2 on the support frame 3 that matches the lumen length or diameter of the lumen instrument to be cleaned. The cleaning personnel hold the brush 2 in one hand and the electric handle 1 in the other hand, with the brush head 21 facing the rotating shaft 12. Insert the rotating shaft 12 into the connecting cavity 2121 until it is fully inserted. At this time, the locking protrusion 2122 enters the locking groove 122, thus completing the connection between the brush 2 and the electric handle 1.

[0048] When cleaning tubular instruments, first insert the front end of the brush 2 into the lumen of the instrument, then turn on the motor by turning on the switch button to make the rotating shaft 12 drive the brush 2 to rotate. The speed of the motor can also be adjusted by the speed adjustment button, and the vibrator can be turned on by the vibration button. The cleaning personnel push and pull the brush back and forth along the lumen to complete the brushing of the inner cavity of the tubular instrument.

[0049] When cleaning tubular instruments of the same specifications, there is no need to replace brush 2; simply repeat the above operation.

[0050] When other sizes of tubular instruments need to be cleaned, pull the brush 2 outward by the brush head 21 to separate the brush head 21 from the rotating shaft 12, put the removed brush 2 back on the support frame 3, and select a brush 2 on the support frame 3 that matches the length or diameter of the other tubular instruments to be cleaned. Repeat the above operation to complete the cleaning of other tubular instruments to be cleaned.

[0051] Obviously, modifications and / or additions can be made to the above-mentioned medical lumen instrument cleaning device and corresponding method without departing from the field and scope of this utility model.

[0052] It is equally clear that, although this invention has described the medical lumen instrument cleaning device in detail, those skilled in the art will certainly be able to obtain many other equivalent forms of medical lumen instrument cleaning devices and corresponding methods that have the features described in the claims and are therefore within the scope of protection defined herein.
