Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to an automatic scrubbing device and an automatic control system for cleaning a flexible endoscope. Background Art

[0002] Endoscopes are a type of testing instrument that integrates traditional optics, ergonomics, precision instruments, modern electronics, mathematics and software. They can be used for inspection, diagnosis, treatment, surgery, etc. They are divided into soft endoscopes and hard endoscopes. Among them, soft endoscopes are soft and bendable laparoscopy, such as gastroscopes, colonoscopes, bronchoscopes, pharyngoscopes, etc., which mainly complete inspection, diagnosis and treatment through the natural cavities of the human digestive tract, respiratory tract, urinary tract, etc.

[0003] The flexible endoscope generally includes the following basic structures: the front end, the bending part, the insertion tube, the operating part, the eyepiece part and the imaging interface part. The front end is the hard part, and the end face has multiple cavities and windows, which are the water and air outlet holes, the biopsy forceps outlet hole, the objective lens and the light guide window. Among them, the water and air supply are the common outlets. When the gas is injected, the gas enters the human body cavity from this hole to expand the cavity; when the water is injected, the water comes out from this hole to wash the objective lens and the surgical field of view, so that the field of view remains clear. The negative pressure suction and the biopsy forceps outlet hole are the same pipe mouth. When there is too much liquid in the cavity that hinders observation, press the suction button, and the liquid can be sucked into the suction bottle from this hole; the biopsy forceps and other treatment instruments also enter the body cavity from this hole. The bending part is located between the front end and the insertion tube. It is composed of many annular parts to form a snake tube. Each pair of adjacent annular parts can move in all directions. The insertion tube is also called the mirror body or hose part, and the interior is various pipes and steel wires. The operating part includes an angle control knob, a suction valve button, a water and air supply button, and a biopsy tube opening. The operator can complete endoscopic examination and treatment by operating various buttons.

[0004] After each use, flexible endoscopes need to be thoroughly cleaned and disinfected or sterilized at a high level. The existing cleaning method is usually manual brushing, that is, each internal channel of the endoscope is manually brushed with a brush, and then disinfected or sterilized. Since flexible endoscopes usually contain multiple channels, the internal structure is relatively complex, and the use of manual brushing has many disadvantages: (1) It is difficult to control the depth of the brush when pushing the brush into the endoscope channel to be cleaned manually. Once the brush does not protrude from the exit of the biopsy channel, the channel will not be brushed properly. In addition, due to the presence of multiple channels, manual operation may result in repeated brushing of the same channel and omission of unbrushed channels. These problems seriously affect the safety of endoscope use and the health of patients; (2) The brushing efficiency is low and the brushing work intensity is high; (3) It is difficult to uniformly record the brushing process of the endoscope, which is not convenient for tracing the relevant information of the brushing of each endoscope, and is not conducive to monitoring.

By inserting long screws into the threaded holes of the three components, the top cover 240, the upper box body 220 and the lower box body 210 can be fixed to each other.

[0055] Furthermore, the transmission assembly is arranged in the housing 200, and the transmission assembly includes a first roller assembly 250 and a second roller assembly 260, and the first roller assembly 250 and the second roller assembly 260 are arranged opposite to each other up and down to form a moving gap between the first roller assembly 250 and the second roller assembly 260. The brush assembly includes a brush head and a lead wire, and the brush head is fixedly connected to one end of the lead wire, and the lead wire is a bendable lead wire with a certain rigidity, such as a thin steel wire, and the length of the lead wire is greater than the length of the channel to be scrubbed; when the brush head and the lead wire are located in the moving gap, the first roller assembly 250 and the second roller assembly 260 are rolled, so that the brush head and the lead wire can be pushed to move in the moving gap, and then the brush head is pushed into the channel to be scrubbed by the movement of the lead wire; by controlling the rolling direction of the first roller assembly 250 and the second roller assembly 260, the movement direction of the brush head can be changed, so that the brush head reciprocates in the channel to be scrubbed to complete the scrubbing action.

[0056] Specifically, Figure 6 , Figure 7 and Figure 8 As shown, a first slot 211 is formed on the side wall of the lower box 210, and the first roller assembly 250 includes a driving shaft 251, on which a bearing 252 is sleeved, and the bearing 252 is clamped in the first slot 211, so that the driving shaft 251 is fixed on the lower box 210.

[0057] A second slot 221 is formed on the side wall of the upper box 220, and the second slot 221 is opposite to the first slot 211. The second roller assembly 260 includes a bracket 261 and a driven shaft. The bracket 261 includes a support plate and two ears arranged opposite to each other. The driven shaft is movably arranged between the two ears and can roll between the two ears. The support plate is clamped in the second slot 221 to connect the second roller assembly 260 to the upper box 220. An elastic pad 262 is sleeved on the driven shaft. Fig. 9 and Fig.10 As shown, the elastic pad 262 is arranged opposite to the washer 254 on the driving shaft 251 to form a moving gap therebetween. The brush assembly is sandwiched between the elastic pad 262 and the washer 254. When the washer 254 rotates with the driving shaft 251, the brush assembly can be pushed to move between the elastic pad 262 and the washer 254.

[0058] Preferably, the transmission assembly includes two or more groups of first roller assemblies 250 and second roller assemblies 260, which can respectively drive two or more brush assemblies to move so as to simultaneously brush two or more channels to be brushed. Of course, the transmission assembly can also include only one group of first roller assembly 250 and second roller assembly 260.

[0059] Further, if Figure 6 , Fig. 9 and Fig.11 As shown, a guide channel 231 is formed in the guide block 230, and the guide channel 231 is connected to the moving gap between the first roller assembly 250 and the second roller assembly 260. One end of the guide channel 231 is corresponding to the brush inlet 201 on the box body 200, and the other end is corresponding to the brush outlet 202. The brush assembly can move from the brush inlet 201 to the brush outlet 202 along the guide channel 231.

[0060] Specifically, four protrusions are provided on the guide block 230, and a groove is formed between two adjacent protrusions, that is, three grooves are formed between the four protrusions of the guide block 230, and three groups of first roller assemblies 250 and second roller assemblies 260 are respectively located in the three grooves.

[0061] The projections are provided with through grooves, and the through grooves in two adjacent projections are located opposite to each other to form a guide channel 231; the moving gap between the first roller assembly 250 and the second roller assembly 260 is arranged corresponding to the through groove, and the through grooves are connected to each other. Fig.11 As shown, three guide channels 231 are formed in the four protrusions. The three groups of first roller assemblies 250 and second roller assemblies 260 are respectively arranged corresponding to one guide channel 231 to guide and transmit the three brush assemblies respectively, and push the three brush assemblies to the three brush outlets 202 respectively.

[0062] Of course, the number of the protrusions on the guide block 230 can also be one, two, three or more than four according to the need of brushing, and the number of the guide channels 231 formed in the protrusions can also be one, two or more than three according to the number of brush assemblies.

[0063] Preferably, the brush inlet 201 on the box 200 is connected to the channel to be brushed of the flexible endoscope through a transparent medical hose. Due to the soft connection, when brushing the channel, there is no need to fix the flexible endoscope, which is convenient for operation. In addition, the transparent hose makes it easier to observe the movement state of the brush assembly.

[0064] Furthermore, the automatic cleaning device for flexible endoscopes in the present invention is preferably Figures 1 to 11 The illustrated embodiment includes three brush assemblies, and correspondingly, three groups of brush inlets 201 and brush outlets 202, as well as three groups of transmission assemblies and guide channels 231 are provided. Since a flexible endoscope generally includes three channels, namely, a water supply channel, an air supply channel and a biopsy forceps channel, when brushing the endoscope, the three channels to be brushed of the flexible endoscope can be connected to the three brush outlets 202 at the same time, so that the three brush assemblies brush the three channels at the same time. This brushing method can improve the brushing efficiency of the endoscope on the one hand, and avoid the problem of missed brushing and repeated brushing of the channels on the other hand, thereby ensuring the brushing quality.

[0065] Furthermore, a controller is provided on the power component 300, and a detection component is communicatively connected to the controller. The detection component can detect the position of the brush component and transmit the detection signal to the controller. The controller can control the start and stop and the movement direction of the transmission component according to the detection signal.

[0066] Specifically, the detection component can be a detection device such as a photoelectric switch or a camera, which is arranged near the transmission component; the brush head of the brush component is placed into the brush inlet 201 on the box 200 manually or by mechanical transmission, so that the brush component moves along the guide channel 231. When the detection component senses that a brush or a lead wire has passed, it will transmit a detection signal to the controller, and the controller will control the power component 300 to start, so that the transmission component pushes the brush component to move. The detection component can also detect the length of the lead wire passing through, and combined with the length of the channel to be brushed, the movement position of the brush head relative to the channel to be brushed can be calculated; when it is detected that the brushing time reaches a preset value and the brush head extends from the outlet of the channel to be brushed, the detection component transmits a detection signal to the controller, and the controller can stop the movement of the power component 300. The controller can also control the rotation direction of the power component 300, and realize the action of the brush head repeatedly brushing the channel by switching between forward and reverse rotation.

[0067] Furthermore, the automatic cleaning device for flexible endoscopes in the present invention also includes an information storage component and an information display component. The information storage component is communicatively connected to the information display component, and the information storage component is communicatively connected to the controller and the detection component. The information storage component can record the cleaning information of the flexible endoscope cleansed by the brush component according to the working conditions of the controller and the detection component, and the information display component can display the cleaning information of the flexible endoscope according to the information recorded by the information storage component.

[0068] Furthermore, the automatic brushing device for flexible endoscopes in the present invention further includes a guide device 400. In some commonly used flexible endoscopes, the entrance of the water supply channel and the air supply channel are the same, which are arranged on the housing of the endoscope. The two channels enter the endoscope through one entrance, and then are divided into two channels inside the endoscope, which are used for water supply and air supply respectively. The guide device 400 is used to connect the automatic brushing device for flexible endoscopes and the entrance of the channel to be brushed of the flexible endoscope. One end of the guide device 400 is connected to the entrance of the flexible endoscope, and the other end is divided into two entrances for the brush assembly to pass through, so that the two brush assemblies can enter the two channels to be brushed from one entrance on the housing of the endoscope respectively.

[0069] Specifically, Fig.12 and Fig.13 As shown, the guide device 400 includes two input ends 401 and an output end 402, the two input ends 401 are respectively connected to the two brush outlets 202 of the box 200, and the output end 402 extends into the shell of the flexible endoscope. Two guide slots 403 are formed inside the guide device 400, and two guide outlets 404 are correspondingly formed on the side wall of the output end 402, one end of each guide slot 403 is connected to an input end 401, and the other end is connected to a guide outlet 404. Each guide outlet 404 is connected to the entrance of a channel to be brushed inside the shell of the flexible endoscope, so that the two brush assemblies can enter the two channels to be brushed inside the shell of the flexible endoscope through the guide device 400. Of course, according to the specific structure of the flexible endoscope to be brushed, the guide device 400 can also be provided with more than two input ends 401 and more than two guide slots 403 and guide outlets 404, so as to correspond to more than two channels to be brushed.

[0070] In addition, a positioning ridge 405 is provided on the guide device 400, and the positioning ridge 405 is located on the outer wall of the output end 402 and protrudes from the outer wall; correspondingly, a groove is provided at the entrance on the soft endoscope shell. When the guide device 400 is installed, the installation position of the guide device 400 can be determined by the mutual cooperation between the positioning ridge 405 and the groove, so that each guide outlet 404 on the guide device 400 accurately corresponds to the entrance of each channel to be brushed inside the endoscope, ensuring that the brush assembly smoothly enters the channel to be brushed.

[0071] The present invention also discloses a control system for an automatic cleaning device for a flexible endoscope, which can be applied to the automatic cleaning device for a flexible endoscope, and specifically comprises:

[0072] The detection unit is arranged near the automatic brushing device of the soft endoscope, and can detect the position of the brush assembly in the automatic brushing device of the soft endoscope, and transmit the detection signal to the control unit. Specifically, the detection unit can use a sensing device such as a photoelectric switch and a camera, and the sensing device is arranged at the brush entrance 201 of the box 200 to detect the position of the brush assembly, collect the time when the brush head enters the box 200 and the time when the lead wire leaves the box 200, that is, the time when brushing starts and the time when brushing ends.

[0073] The control unit is connected to the power component 300 of the automatic brushing device for the flexible endoscope, and can calculate the time required for the brush component to brush the channel to be brushed according to the signal detected by the detection unit, and then control the start and stop of the power component 300, or control the power component 300 to change the transmission direction to brush the channel to be brushed. Specifically, the moment when the brush head enters the box 200 is recorded as time point T1, and the timing is started from this point.
