[0002] Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the development of surgical methods in the future. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open surgeries in the past have been replaced by endoscopic surgeries, greatly increasing the opportunities for surgical selection.

[0003] During laparoscopic surgery, after the doctor finishes the operation, the operating room nurse will soak the front end of the laparoscopic instrument in a multi-enzyme cleaning solution for pretreatment. The biological enzymes in the multi-enzyme cleaning solution can reduce the degree of drying of the surface blood and tissue on the front end of the laparoscopic instrument, which is beneficial for subsequent cleaning and disinfection in the disinfection supply room.

[0004] However, the multi-enzyme cleaning solution is obtained by diluting the multi-enzyme stock solution with pure water. The activity of the biological enzymes in the diluted multi-enzyme cleaning solution has a time limit. In order to ensure that the multi-enzyme cleaning solution achieves the best cleaning effect, the activity of the biological enzymes in the multi-enzyme cleaning solution must be guaranteed. Therefore, the multi-enzyme cleaning solution needs to follow the principle of preparing and using it immediately. However, the workload in the operating room is large and the pace is fast. The operating room nurses are unable to prepare and use the multi-enzyme cleaning solution immediately, so the effect of the multi-enzyme cleaning solution cannot be maximized.

[0035] Embodiment 1, as Figure 1-Figure 4 As shown,

[0036] A portable instrument pretreatment device comprises a reagent tube 1, to which a reagent tube cover 2 is sealed and connected;

[0037] The reagent tube cover 2 is provided with an insertion hole 21, and the insertion hole 21 is used for the front end of the laparoscope instrument to enter the reagent tube 1;

[0038] Two diaphragms 11 are sealed and connected inside the reagent tube 1. The diaphragms 11 separate the inside of the reagent tube 1 into chamber I 12 and chamber II 13. The chamber I 12 is used to store pure water, and the chamber II 13 is used to store multi-enzyme stock solution, so that after the front end of the laparoscope instrument enters the reagent tube 1 and pierces the diaphragm 11, the pure water stored in chamber I 12 is mixed with the multi-enzyme stock solution stored in chamber II 13 to form a multi-enzyme cleaning solution.

[0039] During laparoscopic surgery, after the doctor finishes the operation, the front end of the laparoscope instrument is inserted into the reagent tube 1 through the insertion circular hole 21 formed on the reagent tube cover 2. After the front end of the laparoscope instrument enters the reagent tube 1, the two diaphragms 11 are punctured in sequence, so that the chamber I 12 and the chamber II 13 are connected. The pure water stored in the chamber I 12 and the multi-enzyme stock solution stored in the chamber II 13 are mixed in the reagent tube 1 to form a multi-enzyme cleaning solution. The multi-enzyme cleaning solution is used to soak the front end of the laparoscope instrument, thereby shortening the exposure time of the front end of the laparoscope instrument to the air after use, and greatly reducing the surface of the laparoscope instrument. The drying degree of blood and tissue on the surface reduces the corrosion of blood on the surface of laparoscopic instruments, ensures that the protective layer on the surface of laparoscopic instruments is intact, avoids rust, thereby extending the service life of laparoscopic instruments and saving the cost of hospital maintenance and replacement of new instruments; in this technical scheme, the multi-enzyme stock solution and pure water are stored in the reagent tube 1 at intervals. After the front end of the laparoscopic instrument enters the reagent tube 1, the multi-enzyme stock solution and pure water are mixed to form a multi-enzyme cleaning solution, thereby realizing the ready-to-use multi-enzyme cleaning solution in laparoscopic surgery, which has the beneficial effects of ensuring the pretreatment effect, improving work efficiency and extending the service life.

[0040] As a preferred embodiment, a rubber sheet 3 is sealed and connected inside the reagent tube cover 2, and a hole is formed in the rubber sheet 3 corresponding to the insertion circular hole 21. An annular sealing membrane 31 is integrally provided at the hole, so that after the front end of the laparoscopic instrument enters the reagent tube 1, the annular sealing membrane 31 is sealed and fitted with the tube wall of the laparoscopic instrument.

[0041] After the front end of the laparoscopic instrument enters the reagent tube 1, the multi-enzyme cleaning solution is mixed in the reagent tube 1 and leaks out from the gap between the insertion hole 21 and the laparoscopic instrument. After the multi-enzyme cleaning solution in the reagent tube 1 leaks, the pretreatment effect on the front end of the laparoscopic instrument cannot be guaranteed; therefore, a rubber sheet 3 is sealed and connected in the reagent tube cover 2, and a perforation hole is opened on the rubber sheet 3 corresponding to the insertion hole 21. When the front end of the laparoscopic instrument enters the reagent tube 1, the front end of the laparoscopic instrument is passed through the insertion hole 21 and then through the perforation hole. As the laparoscopic instrument is pushed, the tube wall of the laparoscopic instrument comes into contact with the annular sealing membrane 31. After the front end of the laparoscopic instrument completely enters the reagent tube 1, the annular sealing membrane 31 seals the gap between the tube wall of the laparoscopic instrument and the perforation hole, so that the multi-enzyme cleaning solution in the reagent tube 1 cannot leak out.

[0042] Furthermore, the diaphragm 11 is configured as any one of a QPCR pressure-sensitive diaphragm and an aluminum foil diaphragm. By configuring in this way, the sealing and spacing effect of the diaphragm 11 is ensured, and at the same time, the easy puncture performance of the diaphragm 11 is ensured, so that when the front end of the laparoscope enters the reagent tube 1, the diaphragm 11 can be instantly punctured.

[0043] Furthermore, the reagent tube 1 is configured as a transparent reagent tube, which facilitates observation of the storage state of the pure water in chamber I 12 and the multi-enzyme stock solution in chamber II 13, and facilitates observation of the mixing state of the pure water and the multi-enzyme stock solution after the front end of the laparoscope instrument pierces the diaphragm 11.

[0044] As a preferred embodiment, the reagent tube 1 is sealed with the reagent tube cover 2 in the following manner:

[0045] A connecting tube 22 is integrally provided at the bottom end of the reagent tube cover 2, and the outer wall of the connecting tube 22 is threadedly connected to the inner wall of the reagent tube 1. After the connecting tube 22 is threadedly connected to the reagent tube 1, the bottom end of the reagent tube cover 2 abuts against the top end of the reagent tube 1.

[0046] By threadedly connecting the connecting tube 22 to the inner wall of the reagent tube 1, the reagent tube cover 2 and the reagent tube 1 are sealed to prevent the multi-enzyme cleaning solution in the reagent tube 1 from leaking out from the gap between the reagent tube cover and the reagent tube 1. In addition, by connecting the connecting tube 22 to the inner wall of the reagent tube 1, the outer wall of the reagent tube cover 2 can be arranged parallel to the outer wall of the reagent tube 1, so that the reagent tube 1 can be kept in a relatively horizontal state when placed on its side.

[0047] As a preferred embodiment, a guide tube 23 is also integrally provided in the reagent tube cover 2, and the guide tube 23 is connected through the insertion circular hole 21, and the guide tube 23 is used to guide and limit the laparoscope instrument.

[0048] Since the thickness of the insertion hole 21 is relatively thin, the contact and friction between the laparoscope instrument and the insertion hole 21 will cause wear of the laparoscope instrument; therefore, a guide tube 23 is arranged in the reagent tube cover 2, and the guide tube 23 is connected with the insertion hole 21. The guide tube 23 increases the contact area with the laparoscope instrument to avoid wear of the laparoscope instrument; at the same time, the guide tube 23 limits the movable position of the laparoscope instrument, so that after the front end of the laparoscope instrument enters the reagent tube 1, the front end of the laparoscope instrument is located in the middle position of the reagent tube 1.

[0049] As a preferred embodiment, a limiting plate 4 is fixedly connected inside the reagent tube 1, a limiting hole 41 is provided in the middle position of the limiting plate 4, and a plurality of through holes 42 are also provided on the limiting plate 4. The limiting hole 41 is used to limit the movable position of the front end of the laparoscopic instrument in the reagent tube 1, so that after the front end of the laparoscopic instrument enters the reagent tube 1, it is erected in the middle position in the reagent tube 1 through the limiting plate 4.

[0050] After the front end of the laparoscope instrument enters the reagent tube 1, when the laparoscope instrument is deflected, the front end of the laparoscope instrument will come into contact with the tube wall of the reagent tube 1, and the sharp front end of the laparoscope instrument will cause damage to the tube wall of the reagent tube 1, causing leakage of the multi-enzyme cleaning solution in the reagent tube 1; therefore, a limiting plate 4 is fixedly connected in the reagent tube 1, and after the front end of the laparoscope instrument enters the reagent tube 1, the front end of the laparoscope instrument is located in the limiting hole 41 of the limiting plate 4, and the movable position of the front end of the laparoscope instrument in the reagent tube 1 is limited by the limiting hole 41, so as to avoid the front end of the laparoscope instrument from coming into contact with the tube wall of the reagent tube 1, and the mixing effect of the pure water in chamber Ⅰ12 and the multi-enzyme stock solution in chamber Ⅱ13 is ensured by means of a plurality of through holes 42 opened on the limiting plate 4.

[0051] Embodiment 2, as Figure 5-Figure 7 As shown,

[0052] A portable instrument pretreatment device, based on the above embodiment, a piston 5 is sealed and fitted inside the reagent tube 1, an adjustment hole is opened at the bottom end of the reagent tube 1, the piston 5 is connected to an adjustment rod 51, and the adjustment rod 51 is passed through the adjustment hole. The piston 5 is used to adjust and reduce the space inside the reagent tube 1, so that after the front end of the laparoscope instrument enters the reagent tube 1, the piston 5 is pushed by the adjustment rod 51 to reduce the space inside the reagent tube 1.

[0053] The front end of the laparoscopic instrument pierces the diaphragm 11, and after the pure water and the multi-enzyme stock solution are mixed, the mixed multi-enzyme cleaning solution cannot completely occupy the space in the reagent tube 1, so that the multi-enzyme cleaning solution cannot completely immerse the front end of the laparoscopic instrument; therefore, a piston 5 is sealed and fitted in the reagent tube 1, and the piston 5 is connected to an adjusting rod 51, and the adjusting rod 51 is passed through the adjusting hole; after the front end of the laparoscopic instrument enters the reagent tube 1 and pierces the diaphragm 11, the piston 5 is pushed toward the top of the reagent tube 1 by the adjusting rod 51, and the space in the reagent tube 1 is reduced by pushing the piston 5, so that the mixed multi-enzyme cleaning solution can completely occupy the space in the reagent tube 1, so that the multi-enzyme cleaning solution in the reagent tube 1 can completely immerse the front end of the laparoscopic instrument.

[0054] As a preferred embodiment, the end of the adjusting rod 51 is also connected to a limiting cover 52, the peripheral wall of the limiting cover 52 is connected through the outer wall of the reagent tube 1, the inner bottom end of the limiting cover 52 slides against the bottom end of the reagent tube 1, the top end of the limiting cover 52 is arranged parallel to the top end of the piston 5, and the limiting cover 52 is used to limit the range of movement of the piston 5 in the reagent tube 1.

[0055] The multi-enzyme cleaning solution will occupy most of the space in the reagent tube 1. The piston 5 needs to be pushed to a specified position in the reagent tube 1 so that the multi-enzyme cleaning solution can completely occupy the space in the reagent tube 1. Excessive pushing will cause the multi-enzyme cleaning solution in the reagent tube 1 to leak out. Therefore, a limiting cover 52 is connected to the end of the adjusting rod 51. After the front end of the laparoscopic instrument enters the reagent tube 1 and pierces the diaphragm 11, the inner bottom end of the limiting cover 52 is pushed to abut against the bottom end of the reagent tube 1. The pushing distance of the piston 5 is limited by the limiting cover 52, so that the multi-enzyme cleaning solution can completely occupy the space in the reagent tube 1, and the multi-enzyme cleaning solution in the reagent tube 1 will not leak out. And by setting the top end of the limiting cover 52 parallel to the top end of the piston 5, medical staff can clearly observe the occupancy status of the multi-enzyme cleaning solution in the reagent tube 1 during the pushing process of the piston 5.

[0056] As a preferred embodiment, a limiting ring 6 is also fixedly connected to the outer wall of the reagent tube 1, and a plurality of positioning slides 61 are opened on the outer wall of the limiting ring 6. A plurality of positioning strips 53 are integrally arranged on the inner wall of the limiting cover 52, and the top end of the positioning strip 53 abuts against the bottom end of the limiting ring 6. After the limiting cover 52 is rotated and adjusted, the positioning strip 53 and the positioning slide 61 are clearance-matched.

[0057] When the front end of the laparoscopic instrument has not punctured into the reagent tube 1, the limiting cover 52 arranged on the outside of the reagent tube 1 may be pushed by mistake. If the limiting cover 52 is pushed by mistake, the piston 5 will be pushed in the reagent tube 1, causing the diaphragm 11 to be damaged, and the pure water in the chamber Ⅰ12 and the multi-enzyme stock solution in the chamber Ⅱ13 to mix in advance; therefore, a limiting ring 6 is fixedly connected to the outer wall of the reagent tube 1, and a plurality of positioning sliding openings 61 are provided on the outer wall of the limiting ring 6, and a plurality of positioning strips 53 are integrally provided on the inner wall of the limiting cover 52; at the front of the laparoscopic instrument, When the end has not punctured into the reagent tube 1, the top end of the positioning strip 53 abuts against the bottom end of the limiting ring 6, thereby limiting the movable position of the limiting cover 52, so that the limiting cover 52 cannot be displaced; after the front end of the laparoscope instrument punctures into the reagent tube 1, the limiting cover 52 is rotated and adjusted, and the positioning strip 53 is rotated and adjusted to correspond to the positioning slide 61, and then the limiting cover 52 is pushed, and the positioning strip 53 slides with the clearance of the positioning slide 61, so as to avoid premature mixing of the pure water in chamber Ⅰ12 and the multi-enzyme stock solution in chamber Ⅱ13.

[0058] The above description is only a preferred embodiment of the utility model and is not intended to limit the technical solution of the utility model. For those skilled in the art, the utility model may have various modifications and changes.
