Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an ultrasonic knife head processing device. Background Art

[0002] Ultrasonic scalpels are based on high-frequency mechanical vibrations, which make the tip of the blade produce high-frequency longitudinal mechanical vibrations, thereby achieving tissue cutting and hemostasis. Cutting: The cutting of the ultrasonic scalpel is achieved by the high-frequency vibration impact of the blade head; Hemostasis: The ultrasonic scalpel uses the heat generated by friction to achieve coagulation and hemostasis of the cut tissue, which has a very good effect. It is widely used in medical surgeries at this stage, and the demand for blades has also greatly increased.

[0003] The blade is formed by powder metallurgy, but the consistency of the sintered blade is poor. When assembling, the two blades are easily misaligned, which affects the impact effect. However, in this case, the traditional processing method is manual grinding. Pure manual operation is inefficient, time-consuming and labor-intensive, and cannot accurately position. This also cannot guarantee consistency, resulting in poor product yield and consistency.

[0004] In view of this, the utility model provides an ultrasonic knife head processing device. Utility Model Content

[0005] The utility model provides an ultrasonic knife head processing device, which has a simple structure and is easy to operate, and solves the problem in the related art that the knife head cannot be accurately positioned during processing, affecting product quality.

[0006] The technical solution of the utility model is as follows:

[0007] An ultrasonic knife bit processing device includes a bit positioning mechanism, the bit positioning mechanism includes a base arranged at the bottom, a main frame is arranged on the middle side of the upper part of the base, a bit limiting structure is arranged on the right side of the upper part of the base, and a third hexagon socket screw is arranged between the main frame and the base.

[0008] Preferably, the base of the blade positioning mechanism is provided with a blade limiting structure for positioning the blade, so that the blade of the ultrasonic blade is positioned in the blade limiting structure, and together with the blade pressing mechanism, the blade is firmly pressed in the blade limiting structure.

[0009] Preferably, the blade limiting structure also includes a fixed frame, the top of the fixed frame is fixedly connected to left and right opposite electric push rods, the inner end of the electric push rod is fixedly connected to a movable frame, the top side of the inner end of the movable frame is fixedly connected to a limiting plate, and the blade of the ultrasonic knife is fixed by the limiting plate.

[0011] Preferably, the cutter head clamping mechanism includes a handle arranged at the top for operation, a clamping connecting rod is arranged at the bottom of the handle, a clamping spring is arranged on the clamping connecting rod, a clamping block is arranged at the bottom of the clamping connecting rod, and a fourth hexagon socket screw is arranged between the clamping block and the clamping connecting rod. The cutter head clamping mechanism moves toward the cutter head positioning mechanism, and the operating handle drives the clamping block fixed under the clamping connecting rod to clamp the cutter head, so that the cutter head power mechanism can cut the edge of the cutter head.

[0012] Preferably, the tool head positioning mechanism also includes a first hexagon socket screw and a second hexagon socket screw disposed between the main frame and the tool head power mechanism.

[0013] Preferably, the cutter head power mechanism includes a cutter connecting rod arranged at the upper part, a cutting knife is arranged under the cutter connecting rod, the cutting knife is connected to the cutter connecting rod by a second axle pin, a first washer is arranged on the cutter connecting rod, a cutter reset spring is arranged under the first washer, a sleeve is arranged under the cutter reset spring, a second washer is arranged under the sleeve, a connecting block is arranged under the second washer, a punching handle is arranged under the connecting block, the punching handle is connected to the cutter connecting rod by a cutter handle axle pin, a sliding guide block is arranged on the cutting knife, the cutter head power mechanism is connected with the connecting block and the cutter head positioning mechanism, and the sleeve is limited by the cutter reset spring and two second washers.

[0014] Preferably, the sliding guide block of the cutter head power mechanism is connected to the cutter head positioning mechanism through a second hexagon socket screw, and the cutting knife moves in the sliding guide block. The cutting knife is driven to reciprocate up and down by operating the punching handle, and the cutter head performs precise edge cutting.

[0016] The working principle and beneficial effects of the utility model are:

[0017] In the utility model, left and right electric push rods are arranged opposite to each other at the top of the fixed frame. The electric push rods on both sides cooperate with each other and independently control themselves to extend and retract, so that the cutter head can be fixed when moving synchronously in opposite directions, and the position of the cutter head can be fine-tuned when one side is extended and the other side is shortened. The position fine-tuning function allows the ultrasonic cutter head to be slightly adjusted in position, thereby achieving precise positioning. This is very important for tasks that require high-precision processing and positioning. It can ensure that the cutter head is accurately positioned at the position that needs to be processed. At this time, the clamping handle of the cutter head clamping mechanism is operated downward, and the clamping block of the cutter head clamping mechanism presses the cutter head downward so that it can be fixed in position. At this time, the cutter head is firmly positioned in the limit plates on both sides to prevent the cutter head from shaking in the process of cutting edges, resulting in an inclination of the cutting angle. Then the punching handle of the cutter head power mechanism is operated downward, and the cutting knife of the cutter head power mechanism applies pressure downward to the cutter head, so that the cutter head positioned in the cutter head limiting structure on the base of the cutter head positioning mechanism completes the cutting in the limit plates on both sides. This ensures the consistency of the cutting edges, avoids the time-consuming and labor-intensive manual filing, and the surface roughness and size cannot be guaranteed.
