[0002] As a commonly used surgical instrument, the cleanliness of medical scissors is directly related to medical safety. They must undergo strict cleaning to remove bloodstains, tissue residue, microorganisms, and other contaminants.

[0003] Traditional ultrasonic cleaning equipment lacks a dedicated fixing mechanism, and the scissors are prone to collision due to vibration during the cleaning process, which can lead to blade wear or equipment damage. On the other hand, manual handling of the instruments is required after cleaning, and the process of draining residual liquid is time-consuming and prone to secondary contamination due to improper operation. In addition, traditional equipment is difficult to target and clean key areas such as blade crevices, often requiring secondary processing, which further reduces cleaning efficiency. Therefore, this utility model proposes an ultrasonic cleaning mechanism. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1 - Figure 6 An ultrasonic cleaning mechanism is shown, including a workbench 1, a mounting frame 2 fixedly connected to the upper end of the workbench 1, a first motor 3 mounted on one side of the mounting frame 2 via a bracket, a lifting mechanism 4 for driving the cleaning basket to lift and rotate is mounted on the inner side of the mounting frame 2, a cleaning mechanism 5 for cleaning the blades of medical scissors is mounted on the inner side of the lifting mechanism 4, and two sets of symmetrical sliding grooves are provided on the inner side of the mounting frame 2.

[0024] In this embodiment, the lifting mechanism 4 includes a connecting rod 41 fixedly connected to the output shaft of the first motor 3. A connecting shaft 42 is rotatably connected to the inner side of the connecting rod 41. A slider 43 is fixedly connected to the outer side of the connecting shaft 42. A movable frame 44 is slidably connected to the upper and lower ends of the slider 43. A fixed block 45 is fixedly connected to one end of the movable frame 44.

[0025] Specifically, the connecting rod 41 acts as a power transmission intermediary, transmitting the rotational motion of the first motor 3 to the slider 43 through the connecting shaft 42. When the slider 43 slides in the groove inside the moving frame 44, it can drive the moving frame 44 to move in a straight line, thereby driving the subsequent components to lift and lower through the fixed block 45, providing basic power for the up and down movement of the cleaning basket.

[0026] In this embodiment, the outer side of the fixing block 45 is slidably connected to a set of sliding grooves on the inner side of the mounting bracket 2. The inner side of the fixing block 45 is rotatably connected to a half gear 46 via a rotating shaft. The outer side of the half gear 46 is meshed with a rack 47. One side of the rack 47 is fixedly connected to the mounting bracket 2.

[0027] Specifically, the sliding connection between the fixed block 45 and the inner slide groove of the mounting bracket 2 provides guidance for the lifting movement and ensures the stability of the movement trajectory. The meshing of the half gear 46 and the rack 47 can convert the linear movement of the fixed block 45 into the rotational movement of the half gear 46, thereby providing power for the flipping action of the cleaning basket and realizing the angle adjustment of the cleaning basket when it is immersed in the cleaning tank and drained.

[0028] In this embodiment, a fixed frame 48 is fixedly connected to one end of the half gear 46, and a slide rod 49 is fixedly connected to the other end of the fixed frame 48. The outer side of the slide rod 49 is slidably connected to another set of slide grooves on the inner side of the mounting frame 2, and a cleaning basket is provided at the upper end of the fixed frame 48.

[0029] Specifically, the fixed frame 48 serves as a load-bearing structure, used to install the cleaning basket and connect the half gear 46 and the slide rod 49. It can simultaneously transmit lifting and turning forces. The slide rod 49 is slidably connected to another set of slide grooves of the mounting frame 2, forming a double support structure with the guide of the fixed block 45. This effectively counteracts the lateral forces during lifting and turning, preventing the cleaning basket from shaking or shifting.

[0030] In this embodiment, the cleaning mechanism 5 includes a mounting block 51 fixedly connected to the cleaning basket at the upper end of the fixed frame 48. Four sets of symmetrical electric telescopic rods 52 are installed on the inner side of the mounting block 51, and the output shafts of the four sets of electric telescopic rods 52 are slidably connected to the fixing holes on the inner side of the cleaning basket.

[0031] Specifically, the mounting block 51 provides an installation reference for the components of the cleaning mechanism 5, so that the electric telescopic rod 52 and the second motor 53 are relatively fixed to the cleaning basket. The four sets of electric telescopic rods 52 are symmetrically distributed. Their output shafts are double-limited by passing through the medical scissor handle and the fixing hole of the cleaning basket, which can firmly clamp scissors of different specifications, prevent the scissors from shifting due to vibration during cleaning, and ensure that the blade is accurately aligned with the subsequent brush 57.

[0032] In this embodiment, a second motor 53 is installed on the upper end of the mounting block 51. The output shaft of the second motor 53 is fixedly connected to a first rotating shaft 54. A first bevel gear 55 is fixedly connected to the lower end of the first rotating shaft 54. Two sets of symmetrical second bevel gears 56 are meshed on the outer side of the first bevel gear 55. A brush 57 is fixedly connected to the far end of each of the two sets of second bevel gears 56. The other ends of the two sets of brushes 57 are rotatably connected to the cleaning basket. A protective cover 58 is rotatably connected to the outer side of the first rotating shaft 54. The lower end of the protective cover 58 is fixedly connected to the cleaning basket.

[0033] Specifically, the second motor 53 provides power for blade cleaning, drives the first bevel gear 55 to rotate through the first rotating shaft 54, and drives the two sets of second bevel gears 56 to rotate synchronously in opposite directions using the meshing characteristics of bevel gears, thereby causing the brush 57 to rotate in contact with the blade to specifically remove residual stains in the gaps. The protective cover 58 can prevent the cleaning fluid from contacting the bevel gear set, avoid gear corrosion or jamming, and ensure transmission stability and service life.

[0034] Working principle: When using this device, first activate the four sets of electric telescopic rods 52, causing their output shafts to pass through the handles of the medical scissors and continue to extend until they pass through the corresponding fixing holes inside the cleaning basket, thus fixing the scissors. Then, activate the first motor 3, whose output shaft drives the connecting rod 41 to rotate. The connecting rod 41 drives the slider 43 to move along the slide groove inside the moving frame 44 through the connecting shaft 42. This causes the moving frame 44 to move downward along the slide groove inside the mounting frame 2 through the fixing block 45. The fixing block 45 drives the half gear 46 and the fixing frame 48 to move downward synchronously through the rotating shaft. The fixing frame 48 then drives the cleaning basket and scissors to move downward accordingly. At the same time, the fixing frame 48 drives the sliding rod 49 to move along another set of slide grooves inside the mounting frame 2, making the movement of the fixing frame 48 more stable. When the teeth of the half gear 46 mesh with the rack 47, the half gear 46 drives the fixing frame 48 and the cleaning basket to flip, so that the cleaning basket and scissors are completely submerged in the lower end. The scissors are cleaned in a cleaning tank filled with cleaning solution. At the same time, the second motor 53 on the upper end of the mounting block 51 is started, and its output shaft drives the first rotating shaft 54 ​​to rotate. The first rotating shaft 54 ​​drives two sets of second bevel gears 56 to rotate through the first bevel gear 55. The second bevel gears 56 then drive the brush 57 to rotate, focusing on cleaning the blades of the scissors. The protective cover 58 protects the first bevel gear 55 and the second bevel gear 56 to prevent them from rusting or being damaged due to long-term contact with the cleaning solution. After cleaning, the first motor 3 is started again, and its output shaft drives the fixing frame 48 to move upward through the connecting rod 41. When the half gear 46 meshes with the rack 47 again, the fixing frame 48 flips, so that the opening of the cleaning basket faces downward to drain the residual cleaning solution inside. Then, the electric telescopic rod 52 is started to disengage its output shaft from the fixing hole inside the cleaning basket, so that the scissors can be removed for cleaning the next set of scissors.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
