Description

Technical Field

[0001] The invention relates to the field of ophthalmic phacoemulsification surgery, and in particular to a sterilization box for phacoemulsification surgery instruments. Background Art

[0002] High-pressure steam sterilization is a sterilization method that can kill spores and heat-resistant bacteria. It is suitable for conventional sterilization of common culture media, saline, surgical instruments, glass containers, syringes, dressings, etc. Before and after the doctor completes the operation, it is usually necessary to place the instruments used in the operation in a sterilization box for unified disinfection and sterilization.

[0003] However, ordinary sterilization boxes for surgical instruments usually have some problems in daily use. With the development of science and technology, technicians in related fields have also made a lot of optimizations on sterilization boxes for surgical instruments. In order to make a more accurate comparison, a Chinese patent with publication number CN211355900U discloses a composite dustproof box cover for a surgical instrument tool box suitable for high-pressure steam sterilization, including an outer cover plate, an inner cover plate, air holes and interlayer paper, etc. When in use, the surgical instrument to be processed is placed between the inner cover plate and the outer cover plate, and then the outer cover plate and the inner cover plate are merged together by a screw to complete the placement of the surgical instrument.

[0004] However, the above sterilization box still has some shortcomings in actual use:

[0005] When the above device is in use, the surgical instrument needs to be placed horizontally between the outer cover and the inner cover. However, before the surgical instrument is placed in the sterilization box for high-pressure sterilization, it is usually necessary to use soft water or purified water to clean it. Therefore, if the surgical instrument is a tubular cavity type, after it is placed horizontally in the sterilization box, the droplets remaining in the tubular cavity are difficult to discharge by themselves. After being dried and placed in the high-pressure sterilizer with the sterilization box, the droplets remaining in the tubular cavity will be vaporized and dissipated in the tubular cavity after being penetrated by high-temperature steam, and it is difficult to discharge, causing secondary contamination of the surgical instrument and easily leading to the wet pack problem.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing surgical instrument sterilization boxes. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a sterilization box for ultrasonic emulsification surgical instruments, including a placement bin with openings at both ends and a hollow structure, a plurality of air holes are evenly arranged on the outer surface of the placement bin, and a cover plate is symmetrically connected on both sides of the width direction of the placement bin, and a limiter is arranged on the cover plate for limiting the surgical instruments to be sterilized.

[0008] The limiting member includes a plurality of mounting grooves formed on opposite sides of the two cover plates and along the length direction of the cover plates, a limiting frame is inserted in the mounting groove, a positioning cylinder for positioning the end of the surgical instrument is provided on the limiting frame, and a clamping end for further limiting and positioning the surgical instrument inserted in the positioning cylinder is also provided in the mounting groove.

[0009] Preferably, the clamping end includes a guide slide rod symmetrically inserted in the same mounting groove, a connecting slide rod is provided on the guide slide rod and passes through the connected cover plate, a clamping spring is sleeved on the guide slide rod and is located between the connecting slide rod and the inner side wall of the mounting groove, and a clamping plate is obliquely provided on one end of the connecting slide rod away from the connected guide slide rod.

[0010] Preferably, one end of the clamping plate away from the positioning cylinder is connected to a limiting roller.

[0011] Preferably, the clamping plate is provided with a bending connecting rod of a telescopic structure at one end close to the positioning cylinder, and a semicircular block that contacts the positioning cylinder is provided on the horizontal section of the bending connecting rod. The two semicircular blocks on the same positioning cylinder are symmetrically arranged, and the opposite sides of the two semicircular blocks are abutted against each other and spliced ​​into a complete circular structure.

[0012] Preferably, the opposite sides of the two semicircular blocks are symmetrically arranged as downward slopes, and the inner diameters of the lower end surfaces of the two semicircular blocks are smaller than the inner diameter of the positioning tube.

[0013] Preferably, a connecting slide rod is symmetrically arranged at the lower end of the limit frame, a limit block is sleeved on the connecting slide rod, and a telescopic spring is sleeved on the connecting slide rod and is located between the limit block and the bottom wall of the installation groove.

[0019] 1. The present invention limits a plurality of surgical instruments to be processed in a vertical position in a placement bin. When the placement bin is vertically placed in a high-pressure sterilizer transfer rack, steam can be discharged through a plurality of air holes provided on the outer side of the placement bin, thereby improving the sterilization effect of the sterile bag, reducing the occurrence of wet bags, and achieving the effect of improving the safety of sterile items.

[0020] 2. The present invention drives a plurality of surgical instruments placed in the placement bin to vibrate in the vertical direction, thereby draining the liquid droplets in the ultrasonic emulsification handle more quickly, further avoiding and reducing the occurrence of wet packs, and achieving the effect of improving the safety of sterile items.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 To Attachment Fig.11 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0036] The embodiment of the present application discloses a sterilization box for ultrasonic emulsification surgical instruments, which explains that the sterilization box for ultrasonic emulsification surgical instruments is mainly used in the process of sterilizing ultrasonic emulsification handles, and in terms of technical effect, the ultrasonic emulsification handles that need to be sterilized are limitedly placed in the sterilization box for sterilization; in particular, multiple emulsification handles are limitedly placed in a placement bin in a state perpendicular to a horizontal plane, thereby improving the discharge of droplets in the ultrasonic emulsification handles to avoid the problem of wet packs; further, the sterilization box also drives the ultrasonic emulsification handles placed in the placement bin to shake in the vertical direction, thereby draining droplets in the ultrasonic emulsification handles more quickly, thereby achieving the effect of improving the safety of sterile items.

[0037] Example 1: Reference Figures 1 to 3As shown, a sterilization box for ultrasonic emulsification surgical instruments includes a placement bin 1, air holes 10, a cover plate 11 and a limiter 2. The placement bin 1 is open at both ends and has a hollow structure. A plurality of air holes 10 are evenly arranged on the outer surface of the placement bin 1. The two sides of the placement bin 1 in the width direction are symmetrically connected with the cover plates 11. The two cover plates 11 and the placement bin 1 are connected by a detachable spring buckle structure (not shown in the figure). A limiter 2 for limiting the surgical instruments to be sterilized is arranged on the cover plate 11.

[0038] When in use, the two covers 11 on the placement bin 1 are opened, and then the ultrasonic emulsification handle that needs to be sterilized is placed on the cover 11, and it is limited by the limiter 2 on the cover 11. After the limitation of the ultrasonic emulsification handle is completed, the two covers 11 are reclosed in the placement bin 1, so that a complete chamber space is formed between the two covers 11 and the placement bin 1, and then the closed placement bin 1 is placed on the autoclave transfer rack. Through the high temperature and high pressure environment, the high temperature steam generated in the autoclave is passed into the placement bin 1 through the several air holes 10 on the placement bin 1, so as to complete the effect of high temperature sterilization of all ultrasonic emulsification handles in the placement bin 1.

[0039] Reference Figures 3 to 5 As shown, the limiting member 2 is used to limit the surgical instrument that needs to be sterilized; specifically, the limiting member 2 includes a mounting groove 20, a limiting frame 21, a positioning cylinder 22 and a clamping end 23. A plurality of mounting grooves 20 are formed on opposite sides of the two cover plates 11 and along the length direction of the cover plates 11. A limiting frame 21 is inserted in the mounting groove 20 for limiting the position. A positioning cylinder 22 for positioning the end of the surgical instrument is arranged on the limiting frame 21. A plurality of through holes are jointly provided between the positioning cylinder 22 and the connected limiting frame 21. A clamping end 23 for further limiting and positioning the surgical instrument inserted in the positioning cylinder 22 is also arranged in the mounting groove 20.

[0040] When in use, after opening the two covers 11, the tail end of the ultrasonic emulsification handle is inserted into the positioning tube 22, and then the section of the ultrasonic emulsification handle that is not inserted into the positioning tube 22 is limited and clamped by the clamping end 23, thereby achieving the effect of limiting and clamping the ultrasonic emulsification handle, so that the ultrasonic emulsification handle after being limited is placed vertically in the placement bin 1. The surgical instrument has better hydrophobicity when placed in a vertical state, which can effectively reduce the problem of wet packing and achieve the effect of improving the safety of sterile items.

[0041] Furthermore, breathable absorbent paper for absorbing liquid droplets discharged from the ultrasonic emulsification handle can be set on the inner bottom wall of the positioning tube 22, so as to absorb the liquid droplets discharged from the ultrasonic emulsification handle cleanly, further reduce the problem of wet pack, and achieve the effect of improving the safety of sterile items.

[0042] Reference Figures 3 to 5 As shown, the clamping end 23 is used to further limit and position the surgical instrument inserted in the positioning cylinder 22; specifically, the clamping end 23 includes a guide slide bar 230, a connecting slide bar 231, a clamping spring 232 and a clamping plate 233. The guide slide bars 230 are symmetrically inserted in the mounting groove 20, and the guide slide bars 230 are provided with a connecting slide bar 231 that passes through the connected cover plate 11. The guide slide bar 230 is sleeved with a clamping spring 232 located between the connecting slide bar 231 and the inner side wall of the mounting groove 20, and the connecting slide bar 231 is inclinedly provided with a clamping plate 233 at one end away from the connected guide slide bar 230.

[0043] During use, when the surgical instrument is placed in the positioning cylinder 22, the surgical instrument pushes the clamping plates 233 on both sides to move back and forth in the direction away from the positioning cylinder 22. The movement of the clamping plates 233 drives the connected connecting slider 231 and the guide slide bar 230 to slide synchronously. When the connecting slider 231 slides, the clamping spring 232 connected to it is compressed. After the surgical instrument is placed in the positioning cylinder 22, the clamping springs 232 on both sides of the surgical instrument need to be restored to a normal extended state due to compression. The two clamping springs 232 restore their extension and drive the connected connecting slider 231, the guide slide bar 230 and the clamping plates 233 to slide in a direction close to each other until the two clamping plates 233 are pressed against the outer surface of the surgical instrument, thereby achieving further limiting and clamping effects on the surgical instrument.

[0044] Reference Figure 5 As shown, one end of the clamping plate 233 away from the positioning cylinder 22 is connected to a limiting roller 234, and both ends of the limiting roller 234 are rotatably mounted on the clamping plate 233 through a connecting shaft. When in use, when inserting the surgical instrument downward into the positioning cylinder 22, the clamping plates 233 on both sides drive the connected limiting rollers 234 to abut against the outer surface of the surgical instrument. As the surgical instrument moves downward, the friction between the surgical instrument and the limiting roller 234 drives the limiting roller 234 to rotate, so that the surgical instrument moves downward more quickly and is inserted into the positioning cylinder 22, so as to complete the positioning and limiting effect of the surgical instrument.

[0045] Reference Figure 4 and Figure 5As shown, a bending connecting rod 235 of a telescopic structure is provided at one end of the clamping plate 233 close to the positioning cylinder 22, and a semicircular block 236 that contacts the positioning cylinder 22 is provided on the horizontal section of the bending connecting rod 235. The two semicircular blocks 236 on the same positioning cylinder 22 are symmetrically arranged, and the opposite sides of the two semicircular blocks 236 are abutted against each other and spliced ​​into a complete circular structure. The circular structure after the two semicircular blocks 236 are spliced ​​is concentric with the positioning cylinder 22 that contacts with it. It should be noted that the positioning cylinder 22 and the two semicircular blocks 236 at its upper end are slidably connected, and the two semicircular blocks 236 allow horizontal sliding movement on the positioning cylinder 22.

[0046] When in use, when the clamping plates 233 on both sides are driven by the surgical instrument to slide away from each other, the movement of the clamping plates 233 drives the connected bent connecting rods 235 to move synchronously, and then during the elastic reset process of the clamping springs 232 on both sides, the two semicircular clamping blocks 236 are simultaneously pressed against the outer surface of the surgical instrument, and the two semicircular clamping blocks 236 are also pressed together to form a circular structure to surround the surgical instrument therein, thereby further limiting the surgical instrument and increasing the stability of the positioning cylinder 22 where the surgical instrument is limited.

[0047] Reference Figures 4 to 8 As shown, the opposite sides of the two semicircular blocks 236 are symmetrically arranged as downward slopes 237, and the inner diameters of the lower end surfaces of the two semicircular blocks 236 are smaller than the inner diameter of the positioning cylinder 22, and the inner diameters of the two semicircular blocks 236 are also smaller than the rod diameter of the tail of the surgical instrument. When in use, when the staff inserts the surgical instrument directly downward into the positioning cylinder 22 in a vertical state, the tail of the surgical instrument first conflicts with the slopes 237 on the two semicircular blocks 236, and then drives the two semicircular blocks 236 to slide away from each other along the slopes 237 on the conflicting semicircular blocks 236, and the sliding movement of the two semicircular blocks 236 drives the connected bending connecting rod 235, the clamping plate 233, the connecting slider 231 and the guide slide bar 230 to slide, and the pressing spring 232 on the guide slide bar 230 is compressed.

[0048] Then, under the elastic reset movement of the two clamping springs 232, the connected connecting slider 231, guide slider 230, clamping plate 233, bent connecting rod 235 and semicircular block 236 are driven to slide in the direction of approaching each other, so that the two semicircular blocks 236 are restored to the state of conflicting with each other. As the two semicircular blocks 236 are reset, since the inner diameter of the circular structure after the two semicircular blocks 236 conflict with each other is smaller than the positioning cylinder 22, and is concentrically arranged with the positioning cylinder 22, during the reset movement of the two semicircular blocks 236, through the cooperation with the positioning cylinder 22, the surgical instrument inserted in the positioning cylinder 22 is gradually pushed to be aligned until the two semicircular blocks 236 are counteracted. At this time, the surgical instrument is upward along the axis of the positioning cylinder 22 and perpendicular to the horizontal plane.

[0049] When the staff inserts the surgical instrument into the positioning cylinder 22 in an inclined state, the surgical instrument pushes the clamping plate 233 and the limiting roller 234 to the sides away from each other, and moves downward along the outer side surfaces of the limiting rollers 234 on both sides to contact with the two semicircular clamping blocks 236, and then pushes the semicircular clamping block 236 and the bent connecting rod 235 to separate to the sides along the slope 237 of the semicircular clamping block 236, and drives the connecting slider 231, the clamping plate 233, the limiting roller 234 and the guide slide bar 230 to slide in the direction away from each other again. After the tail of the lower side of the surgical instrument is inserted into the positioning cylinder 22, the two semicircular clamping blocks 236 and the clamping plate 233 slide in the direction close to the surgical instrument under the drive of the tightening spring 232 until the two semicircular clamping blocks 236 and the clamping plate 233 contact the surgical instrument again. At this time, the surgical instrument is also in a state of upward along the axis of the positioning cylinder 22 and perpendicular to the horizontal plane.

[0050] Reference Figure 7 and Figure 8 As shown, a connecting slide rod 24 is symmetrically arranged at the lower end of the limit frame 21 , a limit block 240 is sleeved on the connecting slide rod 24 , and a telescopic spring 241 is sleeved on the connecting slide rod 24 and located between the limit block 240 and the inner bottom wall of the installation groove 20 .

[0051] When in use, when the staff inserts the surgical instrument into the positioning cylinder 22 in a vertical state, the tail of the lower side of the surgical instrument contacts the two semicircular blocks 236, and a downward driving force is applied to the positioning cylinder 22 and the two semicircular blocks 236, driving the positioning cylinder 22, the two semicircular blocks 236 and the limiting frame 21 to move downward in the installation groove 20. The downward movement of the limiting frame 21 drives the two connected connecting slide bars 24 and the limiting blocks 240 to move downward. The downward movement of the two limiting blocks 240 causes the telescopic spring 241 connected thereto to be stretched. After the surgical instrument is inserted into the positioning cylinder 22 and is driven to be aligned by the two semicircular blocks 236, the driving force driving the surgical instrument downward is released. Since the telescopic spring 241 is stretched and needs to be reset, the two limit blocks 240, the two connecting slide bars 24, the limit frame 21, the positioning cylinder 22, the two semicircular blocks 236 and the limited surgical instrument are pulled upward by the reset push of the two telescopic springs 241 until the two telescopic springs 241 are completely reset, so that the upper end of the surgical instrument is inserted between the two clamping plates 233 and the limit rollers 234 and is clamped.

[0052] The outer side surface of the upper side of the surgical instrument is limited by the clamping plates 233 on both sides, and the outer side surface of the lower side of the surgical instrument is limited by the positioning cylinder 22 and the semicircular blocks 236 on both sides, so that the surgical instrument always remains in a vertical state, thereby facilitating the dehydration of the inside of the surgical instrument.

[0053] Reference Figure 7 As shown, the installation groove 20 is also symmetrically provided with a guide block 25 for limiting the position of the limit block 240. When in use, the staff presses the positioning cylinder 22 and the limit frame 21 downward, and the limit frame 21 moves downward to drive the connected connecting slide bar 24 and the limit block 240 to move downward, and after the limit block 240 passes over the guide block 25 at the corresponding position, the guide block 25 limits the position of the limit block 240 and presses it tightly to limit the upward movement of the limit block 240, the connecting slide bar 24, the limit frame 21 and the positioning cylinder 22, so as to facilitate the staff to insert the surgical instrument to be processed into the positioning cylinder 22 for subsequent sterilization.

[0054] Further, in order to facilitate the staff to place the surgical instruments to be processed in the positioning cylinder 22 on the cover plate 11, refer to Fig. 9 As shown, the connecting pins 26 are symmetrically connected on both sides of the length direction of the cover plate 11, and the rotating pins 260 corresponding to the connecting pins 26 are inserted at the limit positions on both sides of the length direction of the storage bin 1. The rotating pins 260 are rotationally connected to the storage bin 1, and the connecting pins 26 and the rotating pins 260 adjacent to the same side are sleeved with a connecting plate 261. When in use, by rotating the cover plate 11 in the direction away from the storage bin 1, the cover plate 11 moves with the connected connecting pins 26 and the connecting plate 261 to rotate, and the connecting plate 261 rotates to drive the rotating pins 260 to rotate and deflect with the axis of the connected rotating pins 260 as the axis, so as to realize the opening of the connected cover plates 11, and the two cover plates 11 on both sides of the two storage bins 1 are symmetrically tilted and opened at a certain angle, so that the staff can insert the surgical instruments to be processed into the positioning cylinder 22.

[0055] Reference Fig. 9 As shown, the lower end of the storage bin 1 is symmetrically provided with a limited slot 27, and the opposite sides of the two cover plates 11 are symmetrically arranged in an arc-shaped structure. When in use, when the two cover plates 11 are skewed and rotated with the rotating pin 260 as the axis, the arc surfaces on the opposite sides of the two cover plates 11 also rotate accordingly. When the lower ends of the opposite sides of the two cover plates 11 are rotated to abut against the side walls of the limited slot 27, the connected cover plates 11 are restricted by the limited slot 27 to continue to skew and rotate. At the same time, the circular surfaces on the opposite sides of the two cover plates 11 also rotate to be on the same horizontal plane as the bottom of the storage bin 1.

[0056] Furthermore, as an optional embodiment, since the deflection angle of the cover plates 11 on both sides of the placement bin 1 will change the overall center of gravity position of the sterilization box after it is placed, when the staff places more surgical instruments in the positioning cylinder 22 on the cover plates 11, it is easy to cause the placement bin 1 to collapse. Therefore, counterweight blocks (not shown in the figure) are installed at the corners around the placement bin 1 to increase the overall stability of the sterilization box when it is unfolded and placed.

[0057] The placement bin 1 and the two cover plates 11 are made of resin material. Resin material is usually lighter than metal, which helps to reduce the overall weight of the sterilization box. Resin has good corrosion resistance and can be used in various harsh environments and chemical media to provide a better sterilization environment.

[0058] Example 2: Reference Figure 8 As shown, on the basis of Example 1, in order to clean out the residual droplets in the surgical instrument after cleaning, so as to improve the rate and effect of subsequent high-temperature and high-pressure sterilization of the surgical instrument, a cleaning piece 3 is provided in a section of the limit frame 21 placed in the mounting groove 20; specifically, the cleaning piece 3 includes a limit slide 30, a driven slider 31 and an adjusting spring 32, a section of the limit frame 21 placed in the mounting groove 20 is provided with a limit slide 30 corresponding to the connecting slide rod 24, the upper end of the connecting slide rod 24 is inserted in the limit slide 30, and the outer side surface of a section of the connecting slide rod 24 placed in the limit slide 30 is sleeved with a driven slider 31 inserted in the limit slide 30, a telescopic spring 241 is provided between the driven slider 31 and the limit block 240, and an adjusting spring 32 is provided between the driven slider 31 and the connected limit slide 30.

[0059] When in use, by moving the limit frame 21 downward, the limit frame 21 moves downward, driving the connected connecting slide bar 24 and the limit block 240 to move downward until they pass over the guide block 25. In the process of moving downward and contacting the guide block 25, the limit block 240 slides along the inclined surface on the guide block 25 in a direction away from the guide block 25. The movement of the limit block 240 drives the connected connecting slide bar 24 and the driven slider 31 to slide synchronously, and makes the adjustment spring 32 connected to the driven slider 31 slide synchronously. After being compressed by the force, it passes the conflicting guide block 25 and then resets and moves in the direction close to the guide block 25 under the reset push of the adjusting spring 32. Finally, the driving force driving the limit frame 21 to move downward is removed. Then, under the drive of the upward elastic reset force of the telescopic spring 241, the limit block 240, the connecting slide bar 24, the driven slide block 31, the limit frame 21 and the surgical instrument are driven to move upward, and the telescopic spring 241 returns to its normal extended state to complete the limiting and installation of the surgical instrument.

[0060] Further, refer to Fig.10 and Fig.11As shown, a mounting frame 33 with a hollow structure is commonly provided between the two inner side walls in the length direction of the placement bin 1, a rotating wheel rod 330 is rotatably penetrated on the mounting frame 33, a driving pulley 331 located in the mounting frame plate is sleeved on the rotating wheel rod 330, and driving impellers 332 located on both sides of the mounting frame 33 are symmetrically sleeved on the rotating wheel rod 330, and an air guide pipe 333 is symmetrically connected to the mounting frame 33, which is sleeved on the outer side surfaces of the rotating wheel rod 330 and the two driving impellers 332 at the same time, and the air guide pipe 333 is arranged parallel to the inner bottom wall of the placement bin 1 and is connected to the inner bottom wall of the placement bin 1. The air holes 10 (not shown in the figure) on the side walls are connected, and a number of air holes 10 (not shown in the figure) are also opened on the mounting frame 33 and the two air ducts 333. An elliptical deflection block 334 is slidably abutted against the upper end of the limiting frame 21, and a rotating wheel rod 330 is also eccentrically connected between the two corresponding deflection blocks 334 on both sides of the placement bin 1. The rotating wheel rod 330 is also sleeved with a synchronous pulley 335 located between the two deflection blocks 334. All the synchronous pulleys 335 and the driving pulley 331 are connected together through a synchronous belt 336.

[0061] When in use, the high-pressure steam generated in the autoclave enters the two air ducts 333 through the air holes 10 on the side wall of the placement chamber 1, and pushes the driving impeller 332 in the air duct 333 to rotate. The driving impeller 332 rotates to drive the connected rotating wheel rod 330 and the driving pulley 331 to rotate. The driving pulley 331 rotates through the synchronous belt 336 to drive all the synchronous pulleys 335 to rotate synchronously. The synchronous pulley 335 rotates to drive the connected rotating wheel rod 330 and the deflection blocks 334 at both ends of the rotating wheel rod 330 to rotate eccentrically. When the long axis of the deflection block 334 rotates to conflict with the limit frame 21, , pushing the limit frame 21, the positioning cylinder 22, the connecting slide bar 24, the driven slide block 31 and the limit block 240 to move downward, the positioning cylinder 22 moves downward to drive the two connected semicircular blocks 236 and the limited surgical instrument to move downward, and after pushing the limit block 240 over the guide block 25, as the deflection block 334 continues to rotate, the long axis of the deflection block 334 gradually breaks away from the conflicting state with the limit frame 21, so that the short axis of the deflection block 334 gradually rotates to conflict with the limit frame 21. In this process, under the reset pull of the connected telescopic spring 241, the limit block 240 is driven to gradually move upward to conflict with the lower end surface of the guide block 25.

[0062] Since the lengths of the major axis and the minor axis of the deflection block 334 are inconsistent, and since the guide block 25 hinders the limit block 240, the major axis and the minor axis of the deflection block 334 are both out of contact with the limit frame 21, and a distance is formed between the deflection block 334 and the limit frame 21, so that the limit frame 21 is temporarily out of the state of being pressed and stressed, and due to the upward contraction of the telescopic spring 241 and the contraction of the adjustment spring 32, the limit block 240 slides along the inclined surface of the guide block 25 in the direction away from the guide block 25. After the limit block 240 passes over the conflicting guide block 25, the adjustment spring 32 drives the limit block 240, the connecting slide rod 24 and the driven slide block 31 to reset in the direction close to the guide block 25. At the same time, driven by the upward contraction of the telescopic spring 241, the limit block 240 is driven to accelerate upward movement and then drive the connecting slide bar 24, the driven slide block 31 and the limit frame 21 to contact the short axis of the deflection block 334. At this time, since the limit frame 21 drives the positioning cylinder 22, the two semicircular blocks 236 and the limited surgical instrument to accelerate upward movement, there is upward inertia, and the limit frame 21 and the positioning cylinder 22 are restrained by the deflection block 334 after moving upward, and the two semicircular blocks 236 are limited by the positioning cylinder 22. Therefore, the surgical instrument inserted in the positioning cylinder 22 continues to slide upward and hit the two semicircular blocks 236 by the inertia of the upward movement at this time, causing the residual droplets in the surgical instrument to accelerate and drip into the positioning cylinder 22 and then be discharged outward.

[0063] It should be noted that the general conventional structure of the ultrasonic emulsification handle is that the tail is larger than the end, and the overall structure is conical. When the ultrasonic emulsification handle is inserted into the positioning tube 22, there is also a gap between the tail end and the two semicircular blocks 236 connected to the upper end of the positioning tube 22, so that the ultrasonic emulsification handle can also slide in the vertical direction when inserted into the positioning tube 22.

[0064] During operation: the first step is to limit and clamp; after opening the two cover plates 11 on both sides of the placement bin 1, the tail of the ultrasonic emulsification handle is inserted into the positioning tube 22 on the cover plate 11, and at the same time, the outer side surface of the ultrasonic emulsification handle is pressed and limited by the two semicircular blocks 236 and the two clamping plates 233 on the positioning tube 22, and the tail of the ultrasonic emulsification handle is limited in the positioning tube 22 by the two semicircular blocks 236, while the ultrasonic emulsification handle is kept inserted in the positioning tube 22 in a vertical shape.

[0065] Step 2: Clean the droplets; after completing the limit installation of all ultrasonic emulsification handles, close the two cover plates 11 and the placement chamber 1 together, and then place the closed sterilization box on the transfer rack of the autoclave. The high-pressure steam in the autoclave drives the ultrasonic emulsification handle on the cover plate 11 to shake and shift, thereby draining the remaining droplets in the ultrasonic emulsification handle.

[0066] Step 3: Sterilization: Place the sterilization box in the autoclave for a period of time, and use the high-pressure steam in the autoclave to further sterilize the sterilization box and all the ultrasonic emulsification handles therein at high temperature and high pressure.
