Cooperative customer: micro-medical
Project Name: Ultrasonic Knife Handle Appearance Design (Scheme A)
Collaboration Scope: Design Analysis | Industrial Design | Structural Design | Prototype Fabrication | Ongoing Support and Assistance
This is the Shanghai Suoguo design for "micro (wedu)" brand to create the ultrasonic scalpel handle scheme A, is a minimally invasive surgery for high-end medical equipment, the following from the multi-dimensional professional dismantling:
Core Positioning and Design Principles of 1. Products
Full name of the product: micro degree (wedu) ultrasonic surgical scissors handle (scheme a)
Core design principles: with the core of ergonomics, create small and convenient minimally invasive surgical instruments that meet the needs of clinical surgery, while ensuring functional reliability, maximize the comfort and accuracy of the doctor's operation.
2. Design Language Analysis
1. Overall modeling language
The use of gun (pistol) grip modeling is a classic man-machine form of surgical instruments, which conforms to the long-term operating habits of doctors and reduces learning costs.
Line language: smooth surface transition, no sharp edges, not only in line with the safety attributes of medical products, but also convey a professional, soft sense of medical treatment;
Proportional control: the whole follows the design of "front thin and rear thick, rear center of gravity", the front end of the work is slender, the rear end of the grip area is full, to ensure the stability of the operation and vision through;
Brand vision: white light green is the main color, white represents clean and professional medical treatment, light green conveys safe and gentle brand tonality, and at the same time strengthens brand recognition through the implantation of brand logo "wedu micro degree.
2. Style positioning
Belongs to the modern medical industrial design style, taking into account the "sense of science and technology" and "humanistic care 」:
Sense of science and technology: through the integration of body modeling, precise structural details, reflecting the high-end technical attributes of medical equipment;
Humanistic sense: through the soft color, fitting the curved surface of the hand, weaken the cold feeling of the instrument, improve the psychological comfort of the operation.
3. Design Detail Disassembly
1. Front-end working end design
Cutter head and sheath tube: adopt slender and slender structure to meet the puncture requirements of minimally invasive surgery and reduce intraoperative tissue damage; the cutter head adopts open-close design to meet the functional requirements of cutting and coagulation;
Protection/positioning structure: the root of the cutter head is designed with a hollow protective structure, which not only plays the role of positioning and limiting, but also reduces the weight through the hollow, and at the same time optimizes the heat dissipation/visual field to avoid blocking the doctor's operation line of sight;
Connection structure: Modular quick connection design is adopted to facilitate the replacement and disinfection of the cutter head, which meets the needs of clinical reuse/one-time use.
2. Fuselage and control area design
Gear adjustment: MAX/MIN double gear button is set above the handle to adjust the ultrasonic energy output. The button adopts convex design, which is convenient for doctors to reach accurately and operate blindly when wearing surgical gloves;
Trigger structure: the double-finger pull trigger is adopted, which is in line with the habit of manual force. The inner side of the trigger is made to fit the finger-shaped curved surface to improve the operation comfort;
Anti-slip design: The grip area of the handle has a horizontal anti-slip texture, even if the hands sweat and wear wet gloves during the operation, it can ensure a stable grip and avoid slipping;
Tail structure: The rear end is designed with a cylindrical metal/plastic end cover to connect the ultrasonic host cable, while balancing the center of gravity of the handle to avoid operating fatigue caused by excessive weight at the front end.
3. Details of the process
Surface treatment: the use of medical grade matte/matte texture, to avoid reflective interference surgical field of vision, while improving the grip friction;
Color separation design: through the white and green two-color partition, the functional area is clearly divided (white is the main structure, green is the grip/operation area), and the visual sense is more layered;
Chamfering treatment: all edges are rounded without sharp edges, which meets the safety requirements of medical products and avoids scratching doctors/patients.
In-depth analysis of 4. ergonomics
1. Adaptation of holding form
The gun shape perfectly adapts to the natural holding posture of the right hand. The radian of the handle fits the palm of the palm. The thumb is naturally placed in the gear button area. The index finger and middle finger pull the trigger. The ring finger and little finger fit the tail of the handle to form a stable holding triangle;
Handle size to do a lightweight, miniaturized design, in line with the "small and convenient" design principles, reduce the doctor's long-term surgery hand fatigue.
2. Operation logic optimization
Gear button position: set in the area that the thumb can easily reach, the energy can be adjusted without changing the holding posture, the operation is consistent, and the surgical process is not interrupted;
Trigger stroke: Optimize the opening and closing stroke and strength of the trigger to ensure that the doctor accurately controls the opening and closing of the cutter head, the operation feedback is clear, and misoperation is avoided;
Center of gravity design: the handle center of gravity, close to the grip area, reduce the front torque, improve the stability of the operation, especially suitable for long-term fine surgery.
3. Clinical scene adaptation
Glove adaptation: all operating parts (buttons and triggers) are designed to be enlarged and convex to meet the operation requirements of doctors wearing sterile surgical gloves and improve the accuracy of operation;
Visual field optimization: the front structure is designed to be slender and hollowed out to minimize the occlusion of the surgical field of view and ensure that the doctor can clearly observe the operation area;
Fatigue relief: by fitting the curved surface of the hand, anti-skid texture, center of gravity optimization, effectively reduce the doctor's long-term surgery hand strain, improve the safety of surgery.
5. Multi-view Design Supplement
The three pictures show the front side perspective, oblique side perspective and back side perspective of the product respectively, fully presenting the design details:
Front side view: clearly shows the overall shape, gear button, trigger structure and cutter head shape;
Oblique side view: presents the curved surface transition of the handle, the anti-slip texture and the man-machine shape of the grip area;
Dorsal perspective: shows the curve of the back of the handle, the protection structure of the cutter head and the color separation design of the body, and verifies the man-machine adaptation of 360 degrees without dead angle.
6. Design Summary
The ultrasonic scalpel handle of Scheme A is a highly unified medical device design with function, man-machine and aesthetics:
Function: to meet the core clinical needs of ultrasonic cutting and coagulation, and the modular design is suitable for clinical use;
Man-machine: take the doctor's operation experience as the core, and optimize the whole process from holding, operation and fatigue relief;
Aesthetically: in line with the professional tonality of medical products, through simple modeling, soft color, transfer brand professional and temperature.
At the same time, the design also reflects the professional ability of Suoguo design in the field of medical devices, and perfectly balances the aesthetic requirements of industrial design and the clinical practicality of medical products. Sogo Design: www.soogot.com
