1. Scheme D Analysis of Depth Design of Ultrasound Knife Handle
1. Design orientation and core principles
Scheme D is an ultrasonic scalpel handle design for the "wedu micro degree" brand. The core design principle is to take the machine engineering as the core to realize the small and convenient products. The goal is to adapt to the minimally invasive surgery scene, meet the needs of surgeons for long-term and high-precision operation, and strengthen the brand's professional medical science and technology image.
2. Design Language Analysis
Scheme D adopts the design language of "professional medical style modern industrial sense", and the overall style is unified and highly recognizable:
Modeling language: it is mainly based on hard lines combined with straight lines and large rounded corners. The gun-style modeling conforms to the classic cognition of medical surgical instruments. At the same time, it weakens the mechanical feeling through smooth curved surface transition, giving consideration to both professionalism and holding comfort.
Color system: the classic medical color matching of white and dark blue is adopted. The white body conveys clean and safe medical attributes. Dark blue is used as embellishment color for anti-skid area, function knob and brand logo, which not only strengthens the visual level, but also highlights the operation area through high contrast, which conforms to the color specification of medical products.
Brand language: the front of the fuselage clearly marked "wedu micro" brand name and English "Ultrasonic Surgical Shears", color and brand vision system unity, strengthen brand recognition, while maintaining the simplicity of medical products, no redundant decoration.
3. Dismantling of key design details
Front end working end design:
The connecting section of the cutter head adopts a hollow heat dissipation structure, which not only reduces the overall weight, but also optimizes the conduction efficiency of ultrasonic vibration. At the same time, the shape conforms to fluid mechanics and reduces the risk of tissue scratching during operation. The knife rod is slim, suitable for the puncture caliber of minimally invasive surgery, and the end jaw has a clear structure to meet the functional requirements of tissue cutting and coagulation.
Middle Ribbon Design:
A dark blue rotating locking structure is arranged between the knife bar and the handle, and the shape is multi-edge anti-skid design, which is convenient for doctors to complete the disassembly and angle locking of the instrument with one hand. The side of the fuselage is designed with vertical anti-skid texture to assist in positioning and exerting force during operation.
Grip area design:
The grip area is made of a large area of dark blue bump non-slip soft rubber, with dense texture and soft touch, which can ensure stable grip even if the hand sweats during the operation. The trigger area is shaped like a curved surface that fits the fingers, and the side of the trigger is increased with longitudinal anti-slip lines to improve the accuracy and comfort of the operation.
Tail structure design:
The tail is a cylindrical cable connection end with a rounded transition shape to avoid interference caused by sharp edges and corners to the operation, while meeting the structural requirements of cable plugging and unplugging, and ensuring stable transmission of ultrasonic energy.
4. Highlights of ergonomic design
The ergonomic design of Scheme D is the core advantage, which is completely optimized around the surgical operation scenario:
Optimized holding posture: the classic gun grip shape conforms to the physiological curve of natural holding of human hands. The length and radian of the grip are suitable for different hand shapes. Long-term holding is not easy to fatigue and meets the needs of long-term operation during surgery.
Optimization of operation logic: the trigger position fits the trajectory of the index finger force, the stroke design is reasonable, the doctor can accurately control the opening and closing of the cutter head through a single finger, and the operation feedback is clear; The position of the function knob is adapted to the thumb operation area, and the parameter adjustment and instrument locking can be completed with one hand, without changing hands, thus improving the operation efficiency.
Optimization of weight and balance: through hollow structure and lightweight material design, the overall weight distribution is balanced, and the weight of the front working end and the rear handle is balanced, thus avoiding the problem of top-heavy and light-heavy operation and reducing the burden on doctors' wrists.
Safety and anti-mistouch design: the functional area and the grip area are clearly distinguished by color and shape, and the anti-slip soft rubber area only covers the grip position to avoid mistouching the function button; The trigger shape is designed to prevent mistouch to prevent accidental triggering during operation.

2. Scheme D optimization direction (optional)
The force feedback structure can be added in the trigger area, so that the doctor can obtain clearer tactile feedback during operation, and further improve the operation accuracy.
It can optimize the shape of the front-end heat dissipation structure, further reduce the weight and improve the operation flexibility while ensuring the heat dissipation efficiency.
The adaptive structure of the sterile handle sleeve can be increased, which is convenient for rapid replacement during the operation and improves the operation efficiency.
