Description

Technical Field

[0001] This utility model relates to a waterproof end plug for cleaning the handle of an ultrasonic scalpel, and a cleaning box having the waterproof end plug. Background Technology

[0002] An ultrasonic scalpel (also known as an ultrasonic blade or ultrasonic hemostatic blade) is an advanced medical device widely used in surgical procedures. The ultrasonic scalpel not only cuts tissue but also has a coagulation function. During cutting, the high-frequency vibration of the blade head can close blood vessels, thereby reducing bleeding. An ultrasonic scalpel consists of a handle and a blade. The handle contains a transducer and circuitry, while the blade is attached to the handle. During surgery, the surgeon holds the handle and inserts the blade into the body to perform the procedure. The blade is disposable; however, the handle is more expensive and is usually reused after rigorous sterilization.

[0003] During the sterilization process, the handle needs to be washed with water to remove surface dirt, and then sterilized in a high-temperature vacuum environment. Further sterilization of the handle's internal components is also required. However, because the mounting hole at the front of the handle where it connects to the blade is open, liquid can easily enter the handle, damaging the internal circuitry and transducer, significantly shortening its lifespan. Furthermore, current cleaning and high-temperature sterilization operations typically require manual transfer between different cleaning devices, which carries the risk of dropping and damaging the handle during transport. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof end plug for cleaning the handle of an ultrasonic scalpel, and a cleaning box having the waterproof end plug, in order to solve one or more problems of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A waterproof end plug for cleaning an ultrasonic scalpel handle, the ultrasonic scalpel handle having a mounting hole for mounting a scalpel, the waterproof end plug comprising:

[0007] A plug body having a plug portion capable of being inserted into the mounting hole in an axial direction, and the plug body having a hollow channel extending through in an axial direction.

[0008] A sealing element is slidably disposed in the hollow channel along the axial direction. The sealing element has a main body rod and a sealing end provided at one end of the main body rod. A sealing part is provided in the hollow channel that can abut against the sealing end in the axial direction. When the sealing end and the sealing part abut against each other in the axial direction, the hollow channel is closed in the axial direction. When the sealing end and the sealing part are disengaged, the hollow channel is open to airflow in the axial direction.

[0009] An expandable component having a closed hollow cavity is disposed in the hollow channel, and the length of the expandable component changes along the axial direction of the plug body when it expands and contracts. One end of the seal abuts against the expandable component along the axial direction, so that the seal can be driven to slide relative to the plug body when the expandable component expands or contracts.

[0010] Preferably, the sealing element further includes a push end, which is disposed at opposite ends of the main body rod along its length, and the push end always abuts against the expandable element along the axial direction.

[0011] In some embodiments, the expandable member is spherical, and an arc-shaped pushing surface is provided on the end of the pushing head facing the expandable member, the arc-shaped pushing surface abutting against the expandable member.

[0012] In some embodiments, the pushing end and the sealing end are slidably connected to the inner peripheral wall of the hollow channel, and the main body rod is spaced apart from the inner peripheral wall of the hollow channel to form a connecting channel between them. The pushing end and the sealing end are respectively provided with a first airflow hole and a second airflow hole extending axially. When the sealing end is disengaged from the sealing part, the first airflow hole communicates with the second airflow hole through the connecting channel to form an axially connected airflow channel.

[0013] In some embodiments, the hollow channel includes a first through hole, a second through hole, and a third through hole connected sequentially along the axial direction. The diameter of the first through hole is larger than the diameter of the second through hole. The stepped surface formed between the first through hole and the second through hole constitutes the sealing part. The main body rod is slidably inserted in the second through hole, and the sealing end is inserted in the first through hole. The expandable member is disposed in the third through hole. The circumferential wall of the third through hole is further provided with a radially outward recessed groove.

[0014] In some embodiments, the waterproof end plug further includes a limiting seat disposed in the third through hole, the limiting seat cooperating with the plug body to restrict the expandable member in the third through hole, and the pushing end head being slidably inserted into the third through hole and connected to the expandable member.

[0015] In some embodiments, the plug body is further provided with an annular limiting boss, the limiting boss extending radially inward from the wall of the third through hole, the limiting seat being supported on the limiting boss, and the limiting seat being provided with an air passage communicating with the third through hole, the air passage being exposed radially outside the limiting boss.

[0016] In some embodiments, a sealing rib extending radially outward is provided on the outer periphery of the plug portion, and the sealing rib has one or a plurality of ribs spaced apart sequentially along the axial direction.

[0017] In some embodiments, the plug is configured to be inserted vertically into the mounting hole, and the sealing end is located above the main body rod.

[0018] A cleaning box for an ultrasonic scalpel handle, the cleaning box comprising:

[0019] The box body has a receiving cavity, and the box body wall is provided with a communicating hole that communicates with the receiving cavity;

[0020] A support base is fixedly mounted on the housing and located in the receiving cavity, and a clamping space is formed on the support base for clamping and fixing the handle of the ultrasonic scalpel;

[0021] A waterproof end plug is disposed on the housing and located within the receiving cavity.

[0022] The waterproof end plug is as described above.

[0023] In some embodiments, the waterproof end plug and the support base are provided in one or more sets corresponding to each other.

[0024] In some embodiments, the cleaning box further includes a winding seat for winding a power cord, the winding seat being fixedly disposed on the box body and located in the receiving cavity, the winding seat and the support seat being spaced apart from each other.

[0025] In some embodiments, the winding base is provided with a winding buckle group, which includes a plurality of winding buckles arranged in rows and spaced apart from each other. The winding base is provided on one side, or the winding base is provided on both opposite sides. The number of winding buckle groups is the same as the number of support bases and corresponds one-to-one.

[0026] Due to the application of the above technical solution, this utility model has the following advantages:

[0027] The waterproof end plug provided by this utility model is inserted into the mounting hole of the connector on the ultrasonic scalpel handle. During the cleaning process of the ultrasonic scalpel handle, the mounting hole is blocked by the waterproof end plug, which closes the hollow channel and prevents liquid from entering the interior of the ultrasonic scalpel handle. When the ultrasonic scalpel handle is placed in a vacuum sterilization environment, the expandable part expands, which opens the hollow channel on the waterproof end plug, making the pressure inside and outside the ultrasonic scalpel handle the same. Sterilization gas can also enter the ultrasonic scalpel handle to sterilize and disinfect its internal components.

[0028] When using the aforementioned waterproof end plug in conjunction with a cleaning box to clean and disinfect the ultrasonic scalpel handle, the box can support the ultrasonic scalpel handle and effectively protect it. It can be transported as a whole or automatically transported by mechanical devices, avoiding or reducing the risk of damage caused by it falling directly to the ground. Attached Figure Description

[0056] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] In this document, the terms “upper,” “lower,” “left,” “right,” etc., which indicate orientation or positional relationship, are defined by reference to the orientation of the ultrasonic scalpel handle during the cleaning process. They are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0058] See Figure 1The ultrasonic scalpel handle 10 shown contains a transducer assembly and other circuit components inside its cavity. The ultrasonic scalpel handle 10 includes a handle body 102 and a connector 101 located at one end of the handle body 102. The connector 101 has a mounting hole through which the scalpel can pass and connect to the connector 101, thereby connecting to the ultrasonic scalpel handle 10. During the cleaning process using a liquid medium, the mounting hole needs to be sealed to prevent liquid from entering the cavity of the ultrasonic scalpel handle 10 through the mounting hole and causing damage to its internal circuit components.

[0059] See Figures 2 to 13 The waterproof end plug 20 shown is detachably connected to the ultrasonic scalpel handle 10, thereby sealing the mounting hole on the connector 101. Specifically, the waterproof end plug 20 includes:

[0060] The plug body 1 includes a plug portion 11 that can be inserted into a mounting hole in an axial direction, and the plug body 1 is also provided with a hollow channel 14 that extends through in an axial direction.

[0061] A sealing element 2 is slidably inserted into a hollow channel 14 along the axial direction. The sealing element 2 has a main body rod 21 and a sealing end 22 disposed at one end of the main body rod 21. A sealing part 15 is disposed in the hollow channel 14, which can abut against the sealing end 22 along the axial direction. When the sealing end 22 and the sealing part 15 abut against each other along the axial direction, the hollow channel 14 is closed along the axial direction, and neither gas nor liquid can reach the other end of the waterproof end plug 20 from one end. When the sealing end 22 is disengaged from the sealing part 15, the hollow channel 14 is open to airflow along the axial direction.

[0062] The expandable component 3 has a closed hollow cavity and is disposed in the hollow channel 14. The length of the expandable component 3 along the axial direction of the plug body 1 can change when it expands and contracts. One end of the sealing component 2 abuts against the expandable component 3 along the axial direction, so that the sealing component 2 can be driven to slide relative to the plug body 1 when the expandable component 3 expands or contracts. This allows the sealing end 22 to engage or disengage from the sealing part 15, thereby allowing the hollow channel 14 to be closed or to be connected by airflow along the axial direction.

[0063] Thus, after the waterproof end plug 20 is inserted into the mounting hole of the connector 101 on the ultrasonic scalpel handle 10, when the ultrasonic scalpel handle 10 is cleaned with liquid, the sealing end 22 can cooperate with the sealing part 15 to seal the hollow channel 14, thereby preventing liquid from entering the interior of the ultrasonic scalpel handle 10 through the mounting hole. When the ultrasonic scalpel handle 10 is sterilized with vacuum / high-pressure gas, the expandable part 3 expands and deforms under the corresponding vacuum pressure, thereby causing the sealing part 2 to slide relative to the plug body 1, so that the sealing end 22 disengages from the sealing part 15, and the hollow channel 14 is opened to allow airflow along the axial direction. The sterilizing gas can then enter the interior of the ultrasonic scalpel handle 10 to thoroughly sterilize and disinfect the internal parts.

[0064] See Figures 2 to 13 As shown, the sealing element 2 also includes a push end 23, which is disposed on opposite ends of the sealing end 22 along the length of the main body rod 21. The push end 23 always abuts against the expandable element 3 along the axial direction. Thus, as the axial dimension of the expandable element 3 changes, the sealing element 2 can slide relative to the plug body 1 accordingly, thereby changing the fit between the sealing end 22 and the sealing part 15. In this embodiment, the expandable element 3 is spherical, and an arc-shaped push surface 23b is provided on the end of the push end 23 facing the expandable element 3. The arc-shaped push surface 23b abuts against the expandable element 3. Specifically, the two are bonded together with an adhesive to maintain mutual fixation.

[0065] In this embodiment, see Figures 4 to 13 As shown, the push end 22 and the sealing end 23 are slidably connected to the inner peripheral wall of the hollow channel 14, respectively. The main body rod 21 is spaced apart from the inner peripheral wall of the hollow channel 14 to form a connecting channel 21a between the two. The push end 22 and the sealing end 23 are respectively provided with a first airflow hole 22a and a second airflow hole 23a extending axially. Here, the first airflow hole 22a and the second airflow hole 23a are both radially outward and each has a plurality of holes distributed circumferentially. When the sealing end 22 is disengaged from the sealing part 15, the first airflow hole 22a is connected to the second airflow hole 23a through the connecting channel 21a to form an axially connected airflow channel, thereby allowing vacuum sterilization gas to pass through.

[0066] Specifically, the hollow channel 14 includes a first through hole 14a, a second through hole 14b, and a third through hole 14c connected sequentially along the axial direction. The diameter of the first through hole 14a is larger than the diameter of the second through hole 14b, and the stepped surface formed between the first through hole 14a and the second through hole 14b constitutes the sealing part 15. The main body rod 21 is slidably inserted into the second through hole 14b, and its rod diameter is smaller than the diameter of the second through hole 14b. The sealing end 22 is inserted into the first through hole 14a, and the outer diameter of the sealing end 22 is basically the same as the diameter of the first through hole 14a, and the two are slidably fitted together. The expandable member 3 is disposed in the third through hole 14c, and the pushing end 22 extends into the third through hole 14c and is connected to the expandable member 3.

[0067] The plug 1 is configured to be inserted vertically into the mounting hole, with the sealing end 22 located above the main body rod 21. That is, during use, the waterproof end plug 20 is positioned as follows: Figures 4 to 6 The state is coordinated with the ultrasonic scalpel handle 10 to form a state like Figure 21 As shown, this prevents liquid from falling into the hollow channel 14 during the cleaning process, and prevents the liquid from entering the interior of the ultrasonic scalpel handle 10 after the sealing end 22 disengages from the sealing part 15.

[0068] like Figure 5 , Figure 6 As shown, when the sealing end 22 abuts against the sealing part 15 downwards, the first airflow hole 22a is closed by the stepped surface, so that the hollow channel 14 cannot be connected in the axial direction; however, when the sealing member 2 moves upwards a certain distance, the sealing end 22 no longer abuts against the sealing part 15, the first airflow hole 22a is not closed by the stepped surface, and it can be connected to the second airflow hole 23a through the connecting channel 21a, so that the hollow channel 14 can be connected in the axial direction for airflow.

[0069] The circumferential wall of the third through hole 14c is further provided with radially outward recessed grooves 14e. These grooves 14e are spaced out circumferentially. This ensures that when the expandable component 3 expands, it does not completely block the circumferential wall of the third through hole 14c, creating a channel between it and the grooves 14e that allows gas to pass through. This avoids the problem of external gas being unable to enter the upper airflow channel after the expandable component 3 expands.

[0070] Referring to the accompanying drawings, in this embodiment, the waterproof end plug 3 further includes a limiting seat 4 disposed in the third through hole 14c. The limiting seat 4 cooperates with the plug body 1 to restrict the expandable member 3 within the third through hole 14c. Specifically, the limiting seat 4 is disposed below the expandable member 3, preventing the expandable member 3 from falling downwards from the third through hole 14c. The pushing end 22 is slidably inserted into the third through hole 14c and connected to the expandable member 3. When the expandable member 3 expands, it can only deform upwards, allowing the sealing member 2 to slide up and down axially.

[0071] The plug body 1 is also provided with an annular limiting boss 14d, which extends radially inward from the wall of the third through hole 14c. The limiting seat 4 is supported on the limiting boss 14d. The limiting seat 4 is also provided with an air passage 41a that communicates with the third through hole 14c. The air passage 41a is exposed radially outside the limiting boss 14d to maintain a state of constant communication with the outside and the third through hole 14c.

[0072] Referring to the accompanying drawings, the plug body 1 also includes a connecting portion 12, which is axially connected to the plug portion 11. The outer diameter of the plug portion 11 is smaller than the outer diameter of the connecting portion 12, forming a stepped surface between them to limit the depth of the plug body 1 into the mounting hole on the connector 101. The connecting portion 12 is also available for the operator to hold and operate, and for connection to other devices. A sealing rib 13 is provided on the outer periphery of the plug portion 11, extending radially outward. This sealing rib 13 may be single or a plurality of ribs spaced apart axially. Thus, when the plug portion 11 mates with the mounting hole, a sufficient seal is formed between them, preventing liquid from entering the interior of the ultrasonic scalpel handle 10.

[0073] The first through hole 14a and the second through hole 14b are both provided in the plug portion 11, and the third through hole 14c is provided in the connecting portion 12. This allows the expandable member 3 to be set to a larger diameter, making it easier to expand and deform when placed in a vacuum environment, thereby driving the sealing member 2 to slide up and down relative to the plug body 1.

[0074] See Figures 14 to 20 As shown, this embodiment also provides a cleaning box 30 for ultrasonic scalpel handles, which is used to contain the ultrasonic scalpel handle 10 for cleaning and disinfection. The cleaning box 30 includes:

[0075] Box 5 has a receiving cavity for holding the ultrasonic scalpel handle 10 to be cleaned. The box wall of box 5 is provided with a connecting hole 51 that communicates with the receiving cavity, so that liquid or gas supplied by an external device can enter the receiving cavity of box 5 through the connecting hole 51 and act on the ultrasonic scalpel handle 10 to be cleaned.

[0076] The support base 7 is fixedly mounted on the housing 5 and located in the accommodating cavity. The support base 7 has two support columns 71 spaced apart, and a clamping space 72 for clamping the ultrasonic scalpel handle 10 is formed between the two support columns 71.

[0077] Waterproof end plug 20, as described above. When the ultrasonic scalpel handle 10 is engaged with the housing 5, the ultrasonic scalpel handle 10 is inserted into the clamping space 72 and fixed relative to the housing 5, with the opening of the mounting hole facing downwards, and the plug portion 11 of the waterproof end plug 20 is inserted into the mounting hole.

[0078] When cleaning and disinfecting the ultrasonic scalpel handle 10, first place the ultrasonic scalpel handle 10 into the receiving cavity of the housing 5, so that the plug 11 is properly inserted into the mounting hole, and the ultrasonic scalpel handle 10 is inserted into the clamping space 72 with the opening of the mounting hole facing downwards, thereby fixing it in the housing 5. Then, place the entire cleaning box containing the ultrasonic scalpel handle 10 to be cleaned into the cleaning equipment, and clean it by spraying water and cleaning solution. The water and cleaning solution enter the receiving cavity of the housing 5 through the connecting hole 51, achieving external cleaning of the ultrasonic scalpel handle 10. During the cleaning process, the mounting hole is sealed to prevent liquid from entering the inner cavity of the ultrasonic scalpel handle 10. Subsequently, the entire cleaning box is placed into a vacuum sterilization device. Under vacuum, the expandable component 3 expands, causing the sealing component 2 to move and disengage from the sealing part 15. This opens the hollow channel 14 of the plug body 1 axially, making the pressure inside and outside the ultrasonic scalpel handle the same. Sterilizing gas can then enter the ultrasonic scalpel handle to sterilize its internal components. During the above process, the box body 5 can support the ultrasonic scalpel handle 10, effectively protecting it. It can be transported as a whole or automatically transported by mechanical devices, avoiding or reducing the risk of damage from direct drops to the ground.

[0079] Specifically, the housing 5 includes a base with its opening facing upwards and a lid that can be closed onto the base. When the lid is closed onto the base, the receiving cavity of the housing 5 is sealed. A locking structure 6 is also provided between the lid and the base to fix them together. In this embodiment, the locking structure 6 consists of two latches provided on at least two opposite sides of the base. These latches can be fastened onto the lid to fix the lid to the top of the base. When the latches are disengaged from the lid, the lid can move relative to the base, thereby opening the receiving cavity, allowing the operator to insert the ultrasonic scalpel handle 10 into the receiving cavity from top to bottom.

[0080] In this embodiment, the waterproof end plug 20 and the support base 7 are both fixed to the bottom plate of the housing 5. The waterproof end plug 20 is located between two support columns 71, which extend vertically, so that the clamping space 72 opens from the top. Therefore, when the ultrasonic scalpel handle 10 is placed into the housing 5, only the opening of the mounting hole needs to face downwards, so that the plug portion 11 of the waterproof end plug 20 is inserted into the mounting hole while it is being placed downwards into the clamping space 72. Of course, in some optional operation methods, the waterproof end plug 20 can be removed from the housing 5 first, inserted into the mounting hole of the ultrasonic scalpel handle 10, and then the waterproof end plug 20 can be inserted into the housing 5 while the ultrasonic scalpel handle 10 is being placed downwards into the clamping space 72.

[0081] In this cleaning tank, the waterproof end plug 20 and the support base 7 are provided in one or more sets, each corresponding to the other. See [reference needed]. Figures 18 to 20 As shown, in this embodiment, three groups are specifically configured so that the housing 5 can simultaneously accommodate and fix three ultrasonic scalpel handles 10. These three ultrasonic scalpel handles 10 are distributed sequentially at intervals along the width direction of the housing 5.

[0082] Referring to the accompanying drawings, the cleaning box also includes a winding seat 8, which is fixedly mounted on the box body 5 and located in the accommodating cavity. The winding seat 8 and the support seat 7 are spaced apart from each other. After the ultrasonic scalpel handle 10 is fixed to the support seat 7, the power cord (not shown in the figure) on the ultrasonic scalpel handle 10 can be wound onto the winding seat 8 to prevent it from being scattered in the accommodating cavity of the box body 5 and to prevent multiple power cords from getting tangled together.

[0083] Specifically, the winding base 8 includes a vertical plate 81 and a winding buckle assembly fixedly mounted on the vertical plate 81. The winding buckle assembly includes multiple winding buckles 82 arranged in rows and spaced apart from each other, so that the same power cord can be wound sequentially around multiple winding buckles 82 without piling up. The winding buckle assembly is provided on one side or opposite sides of the vertical plate 81. The number of winding buckle assemblies is the same as the number of support bases 7 and corresponds one-to-one, so that the power cords of multiple ultrasonic scalpel handles 10 can be wound sequentially.

[0084] When cleaning the ultrasonic scalpel handle 10 using the cleaning box provided in this embodiment, the waterproof end plug 20 is pre-fixed and inserted into the box body 5. Then, the ultrasonic scalpel handle 10 is held with its mounting hole facing downwards and inserted from top to bottom into the clamping space 72 formed by the two support columns 71, so that the mounting hole and the plug part 11 of the waterproof end plug 20 correspond and cooperate, so that the plug part 11 is inserted into the mounting hole. Then, the power cord is wound onto the winding buckle 82 on the winding seat 8, the box cover is closed, and the box cover is locked onto the box base by the locking structure 6. The entire cleaning box containing the ultrasonic scalpel handle 10 to be cleaned is first placed into the cleaning equipment and cleaned by spraying water and cleaning solution. Then it is sent to the sterilization equipment, where sterilizing gas is used to sterilize and disinfect the inside and outside of the ultrasonic scalpel handle 10. During the cleaning and sterilization process, no liquid will enter the handle and cause damage to the ultrasonic scalpel handle 10. At the same time, the operator can also carry it as a whole or use mechanical devices to carry it automatically, avoiding or reducing the risk of it being damaged by falling directly to the ground.
