Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an ultrasonic surgical aspiration device. Background Technology

[0002] In the field of modern surgery, ultrasonic surgical aspiration has become an important surgical aid. With the continuous advancement of medical technology, higher demands are placed on the precision, efficiency, and safety of surgeries. Ultrasonic surgical aspiration equipment plays a crucial role in the surgical process, and its performance directly affects the surgical outcome and the patient's recovery process.

[0003] Existing ultrasonic surgical aspiration devices still face several challenges in practical applications. During the procedure, the handle, as the part that directly contacts the surgical site, frequently comes into contact with tissue debris, blood clots, and other contaminants. Currently, handle clearing blockages is primarily done manually. Medical staff need to spend time and effort disassembling the handle and using tools (such as tweezers and brushes) to remove any remaining tissue and other contaminants during or after surgery. This manual cleaning method has several drawbacks. Firstly, manual cleaning is difficult to completely remove tiny particles and contaminants adhering to the internal channel walls of the handle, easily leading to incomplete cleaning. Residual substances may cause recurring blockages in subsequent surgeries. Secondly, the process of manually disassembling and cleaning the handle is cumbersome, increasing the workload of medical staff and potentially damaging the handle due to improper operation, shortening its lifespan, and increasing surgical costs.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are:

[0019] This invention provides an ultrasonic surgical aspiration device. The trolley is supported on the ground by a wheel assembly, facilitating movement of the device within the operating room and allowing medical staff to flexibly adjust its position according to surgical needs. The handle assembly connects to the main unit, allowing medical staff to control the ultrasonic energy output and tissue aspiration operation. A peristaltic pump assembly works in conjunction with the handle assembly, providing cleaning fluid to the handle. This cleaning fluid is precisely delivered to the handle assembly via the pump assembly and tubing, and then to the blade. Due to its high specific heat capacity, the flowing cleaning fluid quickly absorbs the heat generated by the blade and removes it through heat exchange. Furthermore, it allows for direct cleaning of the surgical area during surgery, maintaining its cleanliness and ensuring a clear surgical field. This contributes to improved surgical precision, reduces damage to surrounding healthy tissue, and ultimately enhances surgical quality and lowers surgical risks. A negative pressure vacuum pump provides ample power for the entire aspiration process. The aspiration canister is mounted on a trolley, its layout facilitating the collection of various tissue debris, blood clots, and other aspirated materials generated during surgery, while also simplifying subsequent cleaning and maintenance. The suction port of the negative pressure vacuum pump is connected to the filter and the outlet of the aspiration canister via a tubing kit, forming a highly efficient aspiration channel. The filter effectively intercepts tissue debris, blood clots, and other contaminants, preventing them from entering the vacuum pump and protecting it from damage, ensuring the long-term stable operation of the negative pressure system. Simultaneously, the filter prevents blockages caused by the accumulation of contaminants within the system, ensuring smooth aspiration. This negative pressure system can promptly and thoroughly aspirate tissue debris, blood, and other contaminants that come into contact with the handle assembly into the aspiration canister, effectively maintaining the cleanliness of the surgical area, significantly improving the clarity of the surgical field, and providing strong support for medical personnel to accurately operate surgical instruments. Compared to existing technologies, its negative pressure system can promptly and thoroughly remove residual dirt from the handle, effectively preventing blockage, ensuring stable transmission of ultrasonic energy, improving the treatment effect of surgical instruments on tissues, reducing the risk of surgical interruption, shortening surgical time, alleviating patient pain, and providing a strong guarantee for the stable conduct of surgery.

Detailed Implementation

[0025] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides an ultrasonic surgical aspiration device, including a main unit 1, a trolley 2, a negative pressure system, a handle assembly, a tubing kit 7, a peristaltic pump assembly, and a wheel assembly; the main unit 1 is placed on the trolley 2, and the trolley 2 is supported on the ground by the wheel assembly; the handle assembly is connected to the main unit 1; the tubing kit 7 is connected to the handle assembly via the peristaltic pump assembly, and the tubing kit 7 can provide cleaning fluid to the handle assembly; the negative pressure system includes a negative pressure vacuum pump 31, a suction tank 32, and a filter 33; the negative pressure vacuum pump 31 is disposed inside the main unit 1, the suction tank 32 is disposed on the trolley 2, the suction port of the negative pressure vacuum pump 31 is connected to the filter 33 and the air outlet of the suction tank 32 in sequence through the tubing kit 7, and the air inlet of the suction tank 32 is connected to the handle assembly.

[0028] Specifically, the trolley 2 is supported on the ground by a wheel assembly, facilitating the movement of the device within the operating room and allowing medical staff to flexibly adjust its position according to surgical needs. The handle assembly connects to the main unit 1, allowing medical staff to control its ultrasonic energy output and tissue suction operations. The peristaltic pump assembly works in conjunction with the handle assembly, providing cleaning fluid to the handle. This cleaning fluid is precisely delivered to the handle assembly via the peristaltic pump assembly and tubing kit 7, and then to the blade head. Due to its high specific heat capacity, the flowing cleaning fluid quickly absorbs the heat generated by the blade head and removes it through heat exchange. Furthermore, it allows for direct cleaning of the surgical area during surgery, maintaining its cleanliness and ensuring a clear surgical field. This contributes to improved surgical precision, reduces accidental damage to surrounding healthy tissues, thereby enhancing surgical quality and lowering surgical risks. The negative pressure vacuum pump 31 provides sufficient power for the entire aspiration process. The aspiration canister 32 is mounted on the trolley 2, and its layout facilitates the collection of various tissue debris, blood clots, and other aspirated materials generated during the operation. It also facilitates subsequent cleaning and maintenance of the aspiration canister 32. The suction port of the negative pressure vacuum pump 31 is connected to the filter 33 and the air outlet of the aspiration canister 32 in sequence through the tubing kit 7, forming a highly efficient suction channel. The filter 33 can effectively intercept tissue debris, blood clots, and other contaminants, preventing them from entering the vacuum pump, protecting the vacuum pump from damage, and ensuring the long-term stable operation of the negative pressure system. At the same time, the filter 33 also avoids the problem of blockage caused by the accumulation of contaminants in the system, ensuring the smoothness of the aspiration process. Through this negative pressure system, tissue debris, blood, and other contaminants that come into contact with the handle assembly can be promptly and thoroughly aspirated into the aspiration canister 32, effectively maintaining the cleanliness of the surgical area, significantly improving the clarity of the surgical field, and providing strong support for medical staff to accurately operate surgical instruments. Compared to existing technologies, its negative pressure system can promptly and thoroughly remove residual dirt from the handle, effectively preventing blockage, ensuring stable transmission of ultrasonic energy, improving the treatment effect of surgical instruments on tissues, reducing the risk of surgical interruption, shortening surgical time, alleviating patient pain, and providing a strong guarantee for the stable conduct of surgery.

[0029] Furthermore, such as Figure 1As shown, the peristaltic pump assembly includes a peristaltic pump 41 and a saline bag 42; the saline bag 42 and the peristaltic pump 41 are mounted on the main unit 1; the outlet of the saline bag 42 is connected to the peristaltic pump 41 via a tubing kit 7, and the tubing kit 7 is connected to the handle assembly via the peristaltic pump 41. Specifically, the outlet of the saline bag 42 is connected to the inlet of the peristaltic pump 41 via the tubing kit 7, and the outlet of the peristaltic pump 41 is connected to the handle assembly via the tubing kit 7. The peristaltic pump 41 works by using its internal rollers to sequentially squeeze the elastic delivery tube, creating a negative pressure inside the tube and propelling the cleaning fluid in one direction. This method allows for precise control of the delivery volume and speed of the cleaning fluid, ensuring a stable and appropriate amount of cleaning fluid is provided to the handle assembly as needed during surgery. Moreover, due to the characteristics of the peristaltic pump 41, it can adapt to cleaning fluids of different viscosities and exerts minimal shear force on the cleaning fluid during operation, effectively preventing damage to any active ingredients or cells that may be present in the cleaning fluid.

[0030] Furthermore, such as Figure 1 As shown, a hook 11 is provided on one side of the main unit 1, and the saline bag 42 is mounted on the hook 11. This allows medical staff to easily access the saline bag 42 when it needs to be replaced or checked, improving the convenience of operation.

[0031] Furthermore, such as Figure 1 As shown, the handle assembly includes a curved handle 51 and a straight handle 52; the curved handle 51 and the straight handle 52 are respectively connected to the main unit 1; the tubing kit 7 is connected to the curved handle 51 and the straight handle 52 via a peristaltic pump assembly. Specifically, the tubing kit 7 is connected to the curved handle 51 and the straight handle 52 via a peristaltic pump 41, providing cleaning fluid to the curved handle 51 and the straight handle 52; the air inlet of the suction canister 32 is connected to the curved handle 51 and the straight handle 52 via the negative pressure suction tube of the tubing kit 7. The curved handle 51 is suitable for surgical scenarios that require operation at special angles or in confined spaces, such as deep tissue surgery or surgery near vital organs. The curved handle 51 can better adapt to the anatomical structure of the surgical site, allowing medical staff to operate the ultrasonic surgical suction device more flexibly, improving the precision and operability of the surgery. The straight handle 52 is more suitable for routine surgical operations or situations requiring greater operating force. Its linear design facilitates the application of force by medical staff and can more effectively control the output of ultrasonic energy and the suction of tissue.

[0032] Furthermore, such as Figure 1As shown, in this embodiment, the wheel assembly includes four casters 61; the four casters 61 are evenly arranged at the bottom of the trolley 2. Medical personnel can easily push the device to move in all directions, making both straight-line movement and turning operations very convenient. Specifically, the casters 61 are equipped with brakes 62. When it is necessary to fix the device in position for surgical operations, medical personnel can step on the brakes 62 to stop the casters 61 from rotating, thereby ensuring that the device will not move due to accidental collisions or other external forces during the operation.

[0033] Furthermore, in this embodiment, the suction canister 32 is connected to the handle assembly via a flexible tube. Specifically, the negative pressure suction tube is a flexible tube, and a filter element is installed inside the flexible tube. When tissue debris, blood clots, and other contaminants are suctioned from the handle assembly into the suction canister 32, the filter element can perform preliminary filtration of these contaminants inside the flexible tube, preventing larger particles from entering the suction canister 32, reducing the accumulation of contaminants inside the suction canister 32, helping to maintain the stable operation of the negative pressure system, and ensuring the continuous effectiveness of the negative pressure suction.

[0034] The ultrasonic surgical aspiration device provided in this embodiment is used as follows: Medical personnel first push the device to the designated location in the operating room using the four casters 61 at the bottom of the trolley 2, adjusting the device's position according to the layout of the operating table and the surgical requirements. Then, the brake 62 is applied to secure the device and prevent accidental movement during the procedure. Next, the main unit 1, handle assembly, negative pressure system, peristaltic pump assembly, and other components are checked for proper connection and any external damage, ensuring the device is in normal working order. Depending on the type of surgery and the patient's condition, medical personnel set appropriate ultrasonic energy output parameters, such as frequency and power, on the main unit 1. Simultaneously, the foot switch 13 and the drip adjustment unit 12 are used to initially adjust the negative pressure suction pressure of the negative pressure system to a suitable initial value. Medical personnel then hold either the curved handle 51 or the straight handle 52, selecting the appropriate handle based on the surgical site and operational requirements. During tissue removal or cleaning, the ultrasonic energy output is activated, and the ultrasonic head emulsifies and cuts the tissue into tiny particles. Simultaneously, the negative pressure system, through the negative pressure generated by the handle assembly, draws these tissue particles, blood clots, and other debris into the suction container 32, providing a clear surgical view. If the surgical view becomes blurred due to tissue debris or blood during the procedure, medical personnel can press the foot switch 13, which activates the peristaltic pump assembly via the drip control unit. The peristaltic pump 41 delivers saline solution from the saline bag 42 through tubing to the handle assembly, where it is sprayed out from the front of the handle. This reduces the temperature of the handle tip and simultaneously flushes the surgical area, quickly removing debris and maintaining a clear surgical view.

[0035] Example 2:

[0036] This embodiment provides an ultrasonic surgical aspiration device, which includes all the structures of the ultrasonic surgical aspiration device described in Embodiment 1. Further, as... Figure 3 As shown, in this embodiment, a drip adjustment unit 12 is provided inside the main unit 1; a foot switch 13 is connected to the outside of the main unit 1; the foot switch 13 is connected to the drip adjustment unit 12, and the drip adjustment unit 12 is connected to the peristaltic pump assembly; the foot switch 13 can drive the peristaltic pump assembly to provide cleaning fluid to the handle assembly via the drip adjustment unit 12. Specifically, the drip adjustment unit 12 is connected to the peristaltic pump 41 of the peristaltic pump assembly. Controlled by the foot switch 13, it provides medical staff with a more convenient and efficient operating method during surgery. Medical staff can flexibly control the drip adjustment unit 12 through the foot switch 13 according to the actual situation such as the clarity of the surgical field and the degree of contamination of the surgical site, thereby achieving precise adjustment of the timing and amount of cleaning fluid supply.

[0037] Furthermore, such as Figure 3 As shown, in this embodiment, the main unit 1 is also equipped with a proportional solenoid valve assembly 14; the drip adjustment unit 12 is connected to the negative pressure system through the proportional solenoid valve assembly 14; the foot switch 13 can adjust the proportional solenoid valve assembly 14 via the drip adjustment unit 12, thereby adjusting the negative pressure suction pressure of the negative pressure system. During surgery, different surgical procedures and tissue types may require different negative pressure suction pressures. Medical staff can send a signal to the drip adjustment unit 12 via the foot switch 13 according to the actual situation, and the drip adjustment unit 12 can then adjust the opening of the proportional solenoid valve assembly 14 to precisely control the negative pressure suction pressure of the negative pressure system.
