Description

Technical Field

[0001] The utility model belongs to the technical field of endoscope cleaning, and in particular relates to an endoscope cleaning brush which is adaptable to different lumen sizes. Background Art

[0002] In the existing technology, an endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural orifices. The endoscope can be used to see lesions that cannot be displayed by X-rays. Among them, flexible endoscopes mainly complete inspection, diagnosis and treatment through the natural cavity of the human body. For example, gastroscopes, colonoscopes, laryngoscopes, bronchoscopes, etc. mainly enter the human body through the digestive tract, respiratory tract and urinary tract. Soft endoscopes generally have a long and narrow tube (or mirror tube), which needs to be soaked, manually brushed, and disinfected after each use. A cleaning brush is needed to clean the inner cavity of the endoscope. After searching, it was found that the application number "202321569007.6" discloses an "endoscope cleaning brush", in which silicone spiral fin brushes are used as cleaning brush heads to replace traditional bristle brush heads. There is a certain pitch between the silicone spiral fin brushes, and the pitch between the brushes forms a long channel, which makes it easy for water to flow through without obstruction. It is easy to clean and disinfect, has no sanitary dead corners, is easy to clean, can be used repeatedly, reduces medical waste, and is more environmentally friendly. However, the above-mentioned cleaning brush still has certain shortcomings when used. Since the sizes of the inner lumens of the mirror tubes of different endoscopes are different, using a cleaning brush of the same size cannot meet the cleaning needs of endoscopes with different inner cavity sizes. Therefore, we propose a cleaning brush that can adjust the bristle size to meet the cleaning needs of lumens with different inner cavity sizes. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 5 The utility model provides the following technical solutions: an endoscope cleaning brush adaptable to different lumen sizes, comprising a handle 1, a catheter 2 is installed at one end of the handle 1, a guide wire 3 is arranged in the catheter 2, and bristles 4 are arranged at one end of the guide wire 3. A mounting groove 5 is provided at the other end of the handle 1, and a through hole is provided at one end of the mounting groove 5 that passes through the handle 1, an adjusting rod 6 is inserted and connected in the mounting groove 5, one end of the guide wire 3 extends into the mounting groove 5 through the through hole and is connected to the end of the adjusting rod 6, a locking assembly 7 is installed on the surface of the adjusting rod 6 and the handle 1, and the length of the bristles 4 gradually increases from the end of the guide wire 3 to the catheter 2.

[0020] In this embodiment, the locking assembly 7 includes a vertical plate 71 and a locking plate 72. A locking rod 73 is fixedly connected to one side of the vertical plate 71. A tooth groove 74 is provided at the bottom end of the locking rod 73. A locking groove 75 is provided on the surface of the locking plate 72. A locking tooth 76 is provided at the bottom of the locking groove 75.

[0021] Specifically, when the adjusting rod 6 is pushed into the mounting groove 5, the adjusting rod 6 will push the guide wire 3 so that the end of the guide wire 3 extends out of the catheter 2, and when the adjusting rod 6 is pushed, the locking rod 73 will be driven to insert into the locking groove 75, and the locking teeth 76 cooperate with the tooth grooves 74 to fix the use position of the adjusting rod 6, thereby fixing the extension length of the guide wire 3. The longer the extension length of the guide wire 3, the longer the length of the bristles 4. Therefore, in this way, when the pipeline is inserted into endoscopes with different lumen sizes, the bristles 4 can effectively clean endoscopes with lumens of different sizes.

[0022] In this embodiment, a spring 8 is provided in the installation groove 5 , and the spring 8 is sleeved on the outside of the guide wire 3 . Both ends of the spring 8 are connected to the end of the adjustment rod 6 and the installation groove 5 respectively.

[0023] Specifically, through the provided spring 8, when the adjusting rod 6 is pushed inward to push the guide wire 3 out of the catheter 2, the adjusting rod 6 will squeeze the spring 8, and the position of the adjusting rod 6 will be locked and fixed by the locking assembly 7. When the locking assembly 7 releases the position lock of the adjusting rod 6, the spring 8 will push the adjusting rod 6 to move outward, so that the adjusting rod 6 drives the guide wire 3 to retract into the catheter 2.

[0024] In this embodiment, the mounting groove 5 is provided with a makeshift groove 9 at the top of the end of the handle 1, and the handle 1 is provided with two strip grooves 10 passing through the mounting groove 5 at the top of the mounting groove 5. The locking plate 72 is located between the two strip grooves 10, and the height of the locking groove 75 is greater than the height of the locking rod 73.

[0025] Specifically, when it is necessary to release the lock on the adjusting rod 6, the staff only needs to use the thumb to press the locking plate 72 downward. The provided give way groove 9 cooperates with the strip groove 10 to enable the locking plate 72 to move downward, thereby allowing the locking tooth 76 to disengage from the tooth groove 74, thereby releasing the lock on the adjusting rod 6. At this time, under the action of the spring 8, the adjusting rod 6 can be automatically pushed outward, thereby causing the guide wire 3 to automatically retract into the catheter 2.

[0026] In this embodiment, the surface of the handle 1 is provided with an anti-slip texture 11 .

[0027] Specifically, the anti-slip texture 11 prevents the handle 1 from slipping in the hands of the staff when the staff holds the handle 1 to clean the inner cavity of the endoscope.

[0028] Working principle: Since the length of the bristles 4 gradually increases from the end of the guide wire 3 to the inside of the catheter 2, when the guide wire 3 is pushed to move out of the catheter 2 by the adjusting rod 6, the length of the bristles 4 on the surface of the guide wire 3 gradually increases. Therefore, this method can effectively meet the cleaning needs of endoscopes with different inner cavity sizes, and the locking assembly 7 provided can fix the extended length of the guide wire 3. After that, the staff can insert the catheter 2 into the inner cavity of the endoscope and clean the inner cavity of the endoscope with the provided bristles 4. When the cleaning is completed, the catheter 2 is pulled out. After that, the staff only needs to press the locking plate 72 to move the locking plate 72 downward, so that the locking teeth 76 are disengaged from the tooth groove 74. At this time, under the action of the spring 8, the adjusting rod 6 drives the guide wire 3 to move outward, and then the guide wire 3 can automatically retract into the catheter 2, thereby protecting the bristles 4.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
