Description

Technical Field

[0001] The invention relates to a cleaning and disinfecting device for surgical instruments, in particular to a multifunctional cleaning and disinfecting device for laparoscopic surgical instruments. Background Art

[0002] Laparoscopic surgery is a surgery performed using a laparoscope and its dedicated laparoscopic surgical instruments. It has many advantages, such as less trauma, fewer complications, and faster recovery. It has been widely used in abdominal surgery instead of traditional surgery and has achieved good therapeutic effects. Laparoscopic surgical instruments mainly include puncture devices, pneumoperitoneum needles, surgical grasping forceps, surgical scissors, flushing and suction devices, converters, electrocoagulation hooks, ultrasonic scalpels, etc. Most of the instruments are tubular and rod-shaped structures, such as sheaths, cannulas, inner cores, etc., which makes cleaning and disinfection more difficult, especially the cleaning of the inner wall of the pipe.

[0003] At present, most hospitals still use manual disassembly and cleaning methods. Generally, after the operation, the laparoscopic instruments should be immediately soaked in clean water or multi-enzyme cleaning solution for cleaning, and all removable parts should be disassembled, placed separately, and the core of each sleeve should be pulled out and fully soaked; then each part should be carefully cleaned with running water, and the instruments with lumens should be repeatedly scrubbed with a soft brush and flushed with a high-pressure water gun, with the brush heads at both ends as the standard, and all blood and tissue fragments should be thoroughly removed, and other organic substances should be removed at the same time. It can be seen that it has the disadvantages of high labor intensity, time-consuming and labor-intensive, low cleaning efficiency, and poor cleaning effect. In addition, due to the high cost of laparoscopic surgical instruments, many hospitals have fewer laparoscopic surgical instruments but more operations, so if they are not cleaned, dried and disinfected in time, the utilization rate of laparoscopic surgical instruments will be reduced. Although there are special cleaning equipment at present, the disadvantages such as single function, narrow scope of application, low cleaning efficiency and poor effect cannot meet the actual needs.

[0004] In summary, the existing manual cleaning method can no longer meet the practical application requirements. Therefore, there is an urgent need for an automated, multifunctional, and widely applicable integrated cleaning and disinfection device for laparoscopic surgical instruments in practical applications, so as to reduce labor intensity, improve cleaning efficiency and cleaning effect.

[0029] By referring to the exemplary embodiments, the objects and functions of the present invention and the methods for achieving these objects and functions will be explained. However, the present invention is not limited to the exemplary embodiments disclosed below; it can be implemented in different forms. The essence of the description is only to help those skilled in the relevant art to comprehensively understand the specific details of the present invention.

[0030] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0031] Figure 1 and Figure 2 The present invention schematically shows a multifunctional cleaning and disinfecting device 100 for laparoscopic surgical instruments, which comprises: a cabinet 1, a truncated cone-shaped transparent shell 2 located above the cabinet 1, a cleaning rack 3 and a spray brush unit 4 located inside the transparent shell 2, a liquid storage barrel 5 and an air pressure unit 6, a pumping unit 7, a driving mechanism 8 and a control unit 9 located inside the cabinet 1, and a UV disinfection box 10 for disinfection and storage is also provided inside the cabinet 1. The cleaning rack 3 can hold various types of laparoscopic surgical instruments, and the pressure unit 6 and the pumping unit 7 are used to spray high-pressure air and the cleaning liquid in the liquid storage barrel 5 onto the surface and inside of the laparoscopic surgical instruments for cleaning, and the driving mechanism 8 can also drive the cleaning rack 3 to rotate as a whole and produce a centrifugal effect, thereby improving the cleaning efficiency and effect.

[0032] The cleaning frame 3 is in the shape of a cone as a whole, and its outer cover is a transparent shell 2 of matching shape. The cleaning frame 3 includes an annular base 31 with gears on the outside, an annular arc body 32 arranged obliquely above the annular base 31, a mechanical sealing connector 33 located at the upper end of the annular arc body 32, a plurality of guide rails 34 arranged from top to bottom on the periphery of the annular arc body 32, an elastic clamping mechanism 35 fixed above the upper end of the guide rail 34, and a movable clamping mechanism 36 moving along the guide rail 34.

[0033] The driving mechanism 8 includes a motor 81 and a transmission mechanism 82. The annular base 31 is movably arranged above the cabinet 1. The transmission mechanism 82 matches the outer gear of the annular base 31 and drives the entire cleaning frame 3 to rotate horizontally. The annular arc body 32 has an inclined angle of 30 to 60 degrees. Its lower end is fixed on the annular base 31, and its upper end is connected to the mechanical seal connector 33 around, thereby forming a relatively sealed space with the upper surface of the cabinet 1, the annular base 31, and the mechanical seal connector 33. The waste liquid after cleaning flows down along the annular arc body 32 to the annular base 31 and is discharged through the sewage pipe 37 arranged below the annular base 31 for collecting waste liquid.

[0034] The spray brush unit 4 is fixed to the inner side of the transparent housing 2, and includes a plurality of spray heads 41 aligned with the guide rail 34 and a first brush 42, which is connected to the pipeline 75 through the first valve 43, and is mainly used to clean the outer surface of the surgical instrument. The liquid storage barrel 5 includes a first liquid storage barrel 51 and a second liquid storage barrel 52, and different cleaning liquids can be selected according to needs, such as multi-enzyme cleaning liquid, distilled water or mineral-free water. The air compression unit 6 includes an air compressor 61 and a second valve 62 connected to the air compressor 61, which is mainly used to provide high-pressure sprayed air, thereby improving the cleaning efficiency.

[0035] The pumping unit 7 includes a first pump 71 located above the first liquid storage barrel 51 and a third valve 72 connected to the first pump 71, a second pump 73 located above the second liquid storage barrel 52 and a fourth valve 74 connected to the second pump 73, and a pipeline 75 connecting the first valve 43, the second valve 62, the third valve 72 and the third valve 74. The above pumps and valves are all opened and closed by instructions from the control unit 9, so that automatic program operation can be realized.

[0036] like Figure 3As shown, the elastic clamping mechanism 35 comprises a fixed outer cylinder 351 with a through hole 358 at the bottom, a movable inner cylinder 352 located inside the fixed outer cylinder 351 and slidable, a first spring 353 connecting the fixed outer cylinder 351 and the movable inner cylinder 352, and an impeller driving body 354 located at the center of the movable inner cylinder 352 and facing the bottom of the fixed outer cylinder 351; a conical injection hole 355 is provided at the center of the movable inner cylinder 352, and an elastic clamping groove 356 is also provided in the movable inner cylinder 35 facing the injection hole 355. The movable inner cylinder 352 can slide and rotate freely in the fixed outer cylinder 351, and generates elastic force under the action of the first spring 353 when sliding. Moreover, the injection hole 355 is in the shape of a cone with an opening facing outward, and the inner side surface of the injection hole 355 is in the shape of a step. Furthermore, the surface of the outer end of the movable inner cylinder 35 and the inner side of the injection hole 355 are paved with a textured and wear-resistant elastic rubber body 357, so as to better adapt and clamp surgical instruments of different diameters. The elastic step structure inside the injection hole 355 can also play the role of clamping the instrument, effectively preventing it from falling off. If it is a tubular instrument 101, the flat end of the pipe is pressed on the elastic rubber body 357 and the center of the pipe is facing the injection hole 355; if it is a rod-shaped instrument 102, the fixed end of the rod passes through the elastic rubber body 357 and is connected to the elastic slot 356; if it is an instrument of other shapes, it is fixed and clamped according to actual conditions.

[0037] The through hole 358 is connected to the pipeline 75, and the through hole 358 sprays cleaning fluid and high-pressure air directly toward the impeller driving body 354. Under the action of the sprayed fluid and high-pressure air, the impeller driving body 354 rotates and drives the movable inner cylinder 352 to rotate in the fixed outer cylinder 351. Further, the cleaning fluid and high-pressure air enter the movable inner cylinder 352 from the periphery of the impeller driving body 354, and are finally sprayed to the outer surface or inner cavity of the surgical instrument through the spray hole 355, thereby achieving the purpose of cleaning.

[0038] like Figure 4-6 As shown, the movable clamping mechanism 36 includes a housing 361, a fixing ring 362 fixed at the center of one side of the housing 361, a plurality of limiting rods 363 evenly arranged on the other side of the housing 361, a hollow turntable mechanism 366 located in the housing 361 and evenly provided with a plurality of limiting holes 364 and driving points 365, an opening and closing mechanism 367 movably connected to the driving point 365 at one end and movably connected to the fixing ring 362 at the other end, a second spring 368 connecting the limiting rod 363 and the driving point 365, and a base 369 passing through the guide rail 34. The limiting hole 364 is an arc-shaped structure, and the limiting rod 363 passes through the limiting hole 364 and serves to limit the rotation angle of the turntable mechanism 366.

[0039] The opening and closing mechanism 367 includes an arc-shaped connecting rod 367a and an arc-shaped blade 367b. The arc-shaped blade 367b is triangular and has an arc-shaped side, and includes a first end 367c, a second end 367d and a third end 367e. One end of the arc-shaped connecting rod 367a is movably connected to the driving point 365 and the other end is movably connected to the first end 367c. The second end 367d is movably connected to the fixing ring 362. The third end 367e is provided with a rubber roller 367f for clamping the surgical instrument. The opening and closing mechanism 367 coincides with the center line of the movable inner cylinder 352 and is parallel to the guide rail 34. When the movable inner cylinder 352 drives the surgical instrument to rotate, it can also drive the rubber roller 367f to roll on the surface of the surgical instrument, thereby realizing all-round rotation cleaning of the surgical instrument. The rubber roller 367f uses the tension of the second spring 368 to fix the circular end of the surgical instrument, thereby ensuring that the rubber roller 367f can roll on the end surface of the surgical instrument. In addition, the elastic rubber body 357 and the rubber roller 367f, which directly contact and clamp the surgical instrument, are both made of elastic and flexible materials, which not only effectively prevent hard contact damage to the surgical instrument during the cleaning process and increase the service life of the surgical instrument, but can also be used to clamp some irregular parts of the surgical instrument.

[0040] The turntable mechanism 366 includes a turntable body 366a, a turntable extension 366b, and a rotary switch 366c located outside the turntable extension 366b. A cam 366d is also provided outside the turntable extension 366b. A plurality of grooves 341 matching the cam 366d are continuously and evenly spaced on the upper part of the guide rail 34. The cam 366d cooperates with the groove 341 to achieve the fixation and movement of the movable clamping mechanism 36 on the guide rail 34. A pluggable second brush 366e is also provided at the edge of the turntable extension 366b for cleaning the ends of laparoscopic surgical instruments, such as the heads of grasping forceps.

[0041] The opening and closing mechanism 367 is initially in a closed state, at which time the cam 366d is located in the groove 341, and the movable clamping mechanism 36 is fixed on the guide rail 34 and cannot move; when the user turns the rotary switch 366c, the cam 366d is driven to rotate out of the groove 341, and the movable clamping mechanism 36 can move on the guide rail 34. At this time, the clamping position of the laparoscopic surgical instrument is adjusted, and then the rotary switch 366c is released. After that, the cam 366d rotates back to the groove 341 under the action of the second spring 368 and clamps the laparoscopic surgical instrument, thereby realizing the clamping operation of the laparoscopic surgical instrument.

[0042] Preferably, a vertical riser 11 fixed to the cabinet 1 and supporting the mechanical seal connector 33 is further provided at the center of the cleaning rack 3, one end of the vertical riser 11 is fixed to the cabinet 1 and the other end is connected to the mechanical seal connector 33. More preferably, the pipeline 75 extends upward and passes through the vertical riser 11 and is respectively connected to the plurality of through holes 358, wherein the pipeline 75 in the vertical riser 11 is a metal pipe 751, the outer surface of which is wrapped with a heating unit 12, and the temperature of the cleaning liquid and high-pressure gas in the pipeline 75 can be increased by heating, thereby improving the cleaning effect and drying effect of the surgical instrument.

[0043] In addition, Figure 7 also schematically shows the clamping structure diagram of the tubular instrument 101 and the rod-shaped instrument 102; wherein, the two ends of the tubular instrument 101 are clamped and fixed by the rubber roller 367f and the elastic rubber body 357 on the inner side of the injection hole 355; the two ends of the rod-shaped instrument 102 are clamped and fixed by the rubber roller 367f and the elastic card groove 356.

[0044] The cleaning and disinfection method of the multifunctional cleaning and disinfection device 100 for laparoscopic surgical instruments of the present invention is as follows:

[0045] a) First, the laparoscopic surgical instrument is disassembled to remove the cleaning parts, such as pipes, rods or irregular parts, and the cleaning parts or the soaked cleaning parts are installed between the elastic clamping mechanism 35 and the movable clamping mechanism 36 and the movable clamping mechanism 36 is fixed.

[0046] b) The control unit 9 sets the cleaning program, then starts the first pump 71 and / or the second pump 73, and at the same time starts the air compressor 61 and opens all valves. The compressed air and the cleaning liquid are mixed in the pipeline 75 and enter the nozzle 41 and the injection hole 355 and then sprayed to the cleaning component. The gas-liquid fluid impacts the impeller driving body 354 to generate rotation and drive the inner cylinder 352 and the cleaning component to rotate as a whole, so that the gas-liquid mixture has the effect of all-round cleaning and increasing local impact force, especially for blood stains or sticky materials on the inner wall of the pipe. It has an excellent cleaning effect.

[0047] c) The driving mechanism 8 can also be turned on at the same time to drive the cleaning frame 3 and the cleaning component to rotate as a whole, thereby generating centrifugal force to cause the pollutants to fall and be discharged as quickly as possible, thereby enhancing the cleaning effect. When rotating to the bottom of the spray brush unit 4, the nozzle 41 and the first brush 42 can clean the outer surface of the cleaning component.

[0048] d) After cleaning for a period of time, the first pump 71 and / or the second pump 73 are turned off, and the heating unit 12 is turned on at the same time, and the high-temperature compressed gas generated is used to dry and bake the cleaned parts.

[0049] e) After the cleaning components are dried, the driving mechanism 8 and the heating unit 12 are turned off, and after cooling, the cleaning components are removed from the elastic clamping mechanism 35 and the movable clamping mechanism 36 and placed in the ultraviolet disinfection box 10 for sterilization.

[0050] f) Finally, close the UV disinfection box 10, check and assemble all the cleaning parts for use in the operation.

[0051] In summary, the multifunctional cleaning and disinfection device 100 for laparoscopic surgical instruments of the present invention creatively adopts technical solutions such as gas-liquid mixture flushing, centrifugal rotation cleaning, multifunctional flexible clamping mechanism, and integrated drying and disinfection. It has many advantages such as high degree of automation, multiple cleaning methods, a wide range of cleanable parts, high cleaning efficiency, good effect and integrated operation.
