Description

Technical Field

[0001] The present invention relates to the technical field of medical disinfection devices, and particularly to an automatic disinfection device for a minimally invasive cutting device used in pediatric surgery. Background Art

[0002] In minimally invasive pediatric surgery, high-frequency electrosurgical instruments (such as electrosurgical hooks, electrosurgical scissors, bipolar forceps) are core surgical tools. They are characterized by precise structures, special materials (including insulation layers, cables, ceramic coatings, etc.), and are frequently used on different children. Therefore, extremely high requirements are placed on sterilization efficiency and safety. Currently, the disinfection of pediatric electrosurgical instruments mainly relies on traditional autoclave and low-temperature plasma sterilization (such as the Sterrad system), but there are still problems with long turnaround times.

[0003] Autoclave is only applicable to all-metal instruments. Since most electrosurgical instruments contain cables and plastic components, low-temperature plasma sterilization is required, which usually takes 28 - 55 minutes, resulting in surgical delays or the need to equip a large number of spare instruments. How to ensure the smooth progress of the surgery without a large number of prepared instruments is a major challenge.

[0004] Therefore, there is an urgent need for a new automatic disinfection device for a minimally invasive cutting device used in pediatric surgery to provide an effective solution to the defects of the prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic disinfection device for a minimally invasive cutting device used in pediatric surgery to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An automatic disinfection device for a minimally invasive cutting device used in pediatric surgery, comprising a low-temperature plasma sterilization cabinet and a rotating disinfection cabinet: The rotating disinfection cabinet includes a machine base and a housing. The low-temperature plasma sterilization cabinet is located at the rear side of the rotating disinfection cabinet. A semi-cylindrical groove is provided on the front side of the low-temperature plasma sterilization cabinet. The housing is of a semi-cylindrical structure. A pick-up and placement opening is provided on the front side of the housing. The semi-cylindrical groove and the housing form a cylindrical barrel-shaped cavity structure. This cylindrical barrel-shaped cavity structure is divided into six fan-shaped areas with equal shapes and sizes. The front area is an open area, the area on the left front side is a drying area, the area on the right front side is a static area, and the three areas on the rear side are sterilization areas. A rotating shaft is installed at the central position of this cylindrical barrel-shaped cavity structure. The lower end of the rotating shaft extends into the machine base. The rotating shaft is driven by a servo motor installed inside the machine base. Six vertically arranged partitions are provided on the circumferential outer wall of the rotating shaft. A placement unit is formed between adjacent partitions. The placement unit is in a sealed state with the housing or the groove. The placement unit located at the pick-up and placement opening is in an open state. The included angle between adjacent partitions is sixty degrees. A hanging rack is provided in each placement unit. The hanging rack is used to place pediatric minimally invasive cutting instruments. Three plasma release ports are provided in the groove of the low-temperature plasma sterilization cabinet. Each plasma release port faces one sterilization area. A control module is provided inside the machine base. A touch screen is provided on the front side of the machine base. The control module is electrically connected to the low-temperature plasma sterilization cabinet, the touch screen, and the servo motor.

[0008] Further, ventilation holes are provided at the bottom of the drying area. An air collecting hood is provided below the ventilation holes. A vacuum pump is installed inside the machine base. The intake end of the vacuum pump is connected to the air collecting hood through an air pipe.

[0009] Further, a protruding rib is provided on the housing at the drying area position. An electric heating mesh is installed inside the protruding rib. The electric heating mesh is electrically connected to the control module.

[0010] Further, a protruding rib is also provided on the housing at the static area position. An ultraviolet sterilization lamp tube is installed inside the protruding rib. The ultraviolet sterilization lamp tube is electrically connected to the control module.

[0011] Further, a sealing groove is provided at the edge of the partition. A sealing strip is clamped in the sealing groove.

[0012] Further, the housing is made of a transparent material, and the partition is also made of a transparent material.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The present invention realizes the continuous pipeline processing of instruments through a rotating partition design (open area → drying area → sterilization area → static area 7). Three plasma release ports sterilize synchronously, greatly shortening the - minute cycle of traditional low-temperature plasma sterilization. The combination of negative pressure ventilation and electric heating improves the drying efficiency, further compressing the overall sterilization time and meeting the rapid turnover requirements of instruments during surgery.

[0015] 2. In the present invention, the static area is equipped with ultraviolet lamps for regular irradiation, combined with a sealed design to ensure that the sterilized instruments remain sterile for a long time and avoid the risk of secondary contamination after traditional sterilization. The touch screen monitors the instrument status in real time, supports "first in, first out" intelligent scheduling, and ensures the best sterilization effect of the instruments used during surgery.

[0016] 3. The whole-process low-temperature treatment of the present invention (plasma sterilization + ultraviolet + controllable heating) is fully adapted to electrosurgical instruments containing wire materials and plastic components, avoiding damage caused by high-temperature and high-pressure sterilization. The sealing strip and partition isolation design prevent cross-contamination. The transparent cover is convenient for observation, and the ultraviolet light is only activated in the sealed state to ensure operation safety.

[0017] In summary, through automated pipeline sterilization, dual sterilization guarantee, and intelligent inventory management, the present invention systematically solves the defects of slow sterilization, difficult turnover, and high pollution risk of precision instruments in pediatric surgery.

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1 to 9 , an automatic disinfection device for a minimally invasive cutting device for pediatric surgery, including a low-temperature plasma sterilization cabinet 1 and a rotary disinfection cabinet 3: The rotary disinfection cabinet 3 includes a machine base 5 and a housing 19. The low-temperature plasma sterilization cabinet 1 is located at the rear side of the rotary disinfection cabinet 3. A semi-cylindrical groove 26 is provided on the front side of the low-temperature plasma sterilization cabinet 1. The housing 19 is a semi-cylindrical structure. An access port 27 is provided on the front side of the housing 19. The semi-cylindrical groove 26 and the housing 19 form a cylindrical barrel-shaped cavity structure. The cylindrical barrel-shaped cavity structure is divided into six fan-shaped areas with equal shapes and sizes. The front area is an open area 15, the left front area is a drying area 16, the right front area is a static area 17, and the rear three areas are sterilization areas 18. A rotating shaft 8 is rotatably installed at the central position of the cylindrical barrel-shaped cavity structure. The lower end of the rotating shaft 8 extends into the machine base 5. The rotating shaft 8 is driven by a servo motor 7 installed inside the machine base 5. Six vertically arranged partition boards 9 are provided on the circumferential outer wall of the rotating shaft 8. A placing unit 10 is formed between adjacent partition boards 9. The placing unit 10 is in a sealed state with the housing 19 or the groove 26. The placing unit 10 at the position of the access port 27 is in an open state. The included angle between adjacent partition boards 9 is sixty degrees. A hanging rack 11 is provided in each placing unit 10. The hanging rack 11 is used to place pediatric minimally invasive cutting instruments 12. Three plasma release ports 2 are provided in the groove 26 of the low-temperature plasma sterilization cabinet 1. Each plasma release port 2 faces a sterilization area 18; A control module is provided inside the machine base 5. A touch screen 6 is provided on the front side of the machine base 5. The control module is electrically connected to the low-temperature plasma sterilization cabinet 1, the touch screen 6, and the servo motor 7.

[0030] A sealing groove 13 is provided at the edge of the partition plate 9, and a sealing strip 14 is clamped in the sealing groove 13.

[0031] The cover 19 is made of a transparent material, and the partition plate 9 is also made of a transparent material.

[0032] Working principle of this embodiment:

[0033] When this embodiment works, before putting the device in, first perform ultrasonic cleaning on instruments 12 such as electric hooks, electrocoagulation scissors, bipolar electrocoagulation forceps, etc. to remove contaminants such as blood stains and tissue residues to ensure the sterilization effect. Hang the cleaned instruments 12 on the hanging rack 11 and put them into the placement unit 10 in the current open area 15 through the access opening 27. The servo motor 7 drives the rotating shaft 8 to rotate 60°, so that the instruments 12 enter the next area: the drying area 16: natural air drying or assisted drying to avoid residual moisture affecting the plasma sterilization effect. The sterilization area 18: Three plasma release ports 2 work simultaneously for efficient sterilization, greatly shortening the 28 - 55 minutes waiting time required for traditional low-temperature plasma sterilization. After sterilization is completed, the instruments 12 rotate back to the static area 17 with the rotating shaft 8 and wait to be used. When needed, they are then rotated to the open area 15 and taken out for use. Since the six placement units 10 operate in a cycle, continuous sterilization can be achieved without waiting for a single batch to be completed, significantly improving the turnover rate of the instruments. The sealed design of the sealing strip 14 ensures no pollution during the sterilization process, and the transparent cover 19 facilitates real-time monitoring.

[0034] As shown in Table 1, the advantages of this embodiment compared with the traditional method of this implementation:

[0035] Traditional sterilization method This embodiment

[0036] Manual transfer of instruments is required, and the steps are cumbersome

[0037] Fully automatic rotating process, reducing manual intervention and being cumbersome

[0038] Single sterilization takes 28 - 55 minutes Multi-area synchronous sterilization, shortening the waiting time

[0039] A large number of spare instruments are required to cope with the turnover Cycle operation, reducing the number of spare instruments

[0040] Only applicable to some high-temperature resistant instruments Compatible with electrosurgical instruments including cables and plastic parts Table 1

[0041] After the pre-treatment ultrasonic cleaning in this embodiment, through the automated rotating sterilization process, it perfectly solves the problems of slow sterilization and difficult turnover of electrosurgical instruments in pediatric surgery, providing reliable support for the efficient development of minimally invasive surgery.

[0042] Embodiment 2: Please refer to Figures 4 to 5, An automatic disinfection device for a minimally invasive cutting device used in pediatric surgery, which is different from Example 1 in that ventilation holes 22 are provided at the bottom of the drying area 16, a gas collecting hood 23 is provided below the ventilation holes 22, a vacuum pump 25 is installed in the machine base 5, and the intake end of the vacuum pump 25 is connected to the gas collecting hood 23 through a trachea 24.

[0043] On the housing 19 at the position of the drying area 16, there are outwardly protruding ridges 20, and an electric heating grid is installed inside the ridges 20. The electric heating grid is electrically connected to the control module.

[0044] In this embodiment, the ventilation holes 22 are located at the bottom of the drying area 16, communicate with the gas collecting hood 23, and are connected through the suction action of the vacuum pump 25 via the trachea 24 to forcibly discharge the residual moisture on the surface of the instrument 12, greatly shortening the natural drying time. At the same time, the vacuum pump 25 can create a negative pressure in the drying area 16, reduce the water evaporation temperature, and accelerate the evaporation of water.

[0045] The electric heating grid is integrated inside the ridge 20 and is started under the control of the control module to deliver mild hot air to the drying area 16, further promoting water evaporation, and at the same time avoiding damage to the plastic or insulating parts of the instrument 12 due to high temperature. The outwardly protruding design of the ridge 20 expands the heating space to ensure uniform distribution of hot air; its transparent material is the same as that of the housing 19 and does not affect the observation of the instrument state.

[0046] Compared with the natural drying in Example 1, in this embodiment, through the combination of negative pressure ventilation and controllable heating 20, the drying efficiency of the instrument 12 is improved, and the overall sterilization cycle is further compressed.

[0047] Example 3: Please refer to Figures 3 to 4 , An automatic disinfection device for a minimally invasive cutting device used in pediatric surgery, which is different from Example 1 in that outwardly protruding ridges 20 are also provided on the housing 19 at the position of the static area 17, and ultraviolet sterilization lamps 21 are installed inside the ridges 20. The ultraviolet sterilization lamps 21 are electrically connected to the control module.

[0048] In this embodiment, the instrument that has completed plasma sterilization 18 rotates to the static area 17 along with the rotating shaft 8 and remains in a sterile state in this area for use. The closed environment of the static area 17 and the regular irradiation of the ultraviolet lamp 21 ensure that the instrument remains in a sterile state continuously. When the operation requires the use of the instrument, the control module drives the servo motor 7 to rotate the target instrument 12 from the static area 17 to the open area 15. The medical staff directly takes out the sterilized instrument 12 through the access opening 27 to achieve "ready to use immediately". The touch screen 6 real-time displays the instrument status (sterilizing / ready for use / already taken) of each placement unit 10. This embodiment solves the risk of exposure and contamination of traditional sterilized instruments, maintains a sterile state through the dedicated static area 17, realizes the "first in, first out" management of sterilized instruments, ensures the best sterilization effect during the operation, reduces the waiting time of medical staff, and improves the operation efficiency of the operating room.
