Description

Technical Field

[0001] This invention belongs to the field of hemostatic knife technology, and specifically relates to a hemostatic knife with a quick-change blade structure and a method for changing the blade. Background Technology

[0002] Hemostatic knives are mainly used for cutting biological tissues and closing blood vessels. They are characterized by less bleeding, less damage to surrounding tissues, and faster postoperative recovery. They act on human tissues to cut and coagulate without causing side effects such as tissue dryness or burns. No current passes through the human body when the knife is working, and they are widely used in operating rooms.

[0003] Currently, Chinese invention patent CN115581507A discloses an ultrasonic cutting hemostatic knife, relating to the field of medical cutting technology. This ultrasonic cutting hemostatic knife includes an ultrasonic main unit, which is fixedly mounted on a main unit mounting plate. The main unit mounting plate is connected to an upper lifting column. The hemostatic knife includes: a handle upper shell, a drive ball fixing block, and a drive ball. The lower end of the handle upper shell is connected to a drive ball groove. The starting foot pedal includes: a foot pedal base plate and foot pedal suction cups. Four foot pedal suction cups are fixedly installed at the lower end of the foot pedal base plate. The ultrasonic main unit is activated by the starting foot pedal, and sound waves are transmitted to the hemostatic knife through a waveguide harness. The surgeon holds the handle, aligns the fixed blade at the front of the blade with the area to be cut, grips the rear end of the handle upper shell with their thumb, and uses their index finger to activate the drive ball. Cutting is achieved by the floating blade and the fixed blade alternating. Compared to current equipment, this method offers greater stability when holding the knife.

[0004] Existing hemostatic knives with quick-change blades and their replacement methods have the following disadvantages when in use:

[0005] The lack of a quick-change mechanism for the cutting head makes it inconvenient to change the cutting head quickly. At the same time, the lack of a quick-switch mechanism after changing the cutting head makes it impossible to quickly switch back and forth between the required cutting heads, reducing the flexibility of the cutting head during use. Summary of the Invention

The overall structure provides support and limitation, and can temporarily limit the reset component 204, improving the stability of the reset component 204 during replacement. The limiting component 202 can limit the carrier component 201 and the drive mechanism 1, improving the stability of the carrier component 201 after replacement. The movable component 203 can limit the movement of the reset component 204. The reset component 204 can support and limit the loading component 205, and can reinforce the connection between the blade head component 206 and the drive mechanism 1.

The inner side of the limiting ring 2022 contacts the surface of the perforated connecting rod 1023. The limiting hole 2023 is formed inside the limiting ring 2022. The spring rod 2021 is close to the limiting ring 2022, thus... Contacting the inner side of the limiting hole 2023, the spring rod 2021 passes through the limiting hole 2023 on the side near the limiting ring 2022. By setting the limiting component 202, the spring rod 2021 can be connected to the limiting hole 2023 on the limiting ring 2022, and the limiting ring 2022 can be connected to the perforated connecting rod 1023, thereby engaging the perforated connecting rod 1023 with the limiting ring 2022, so as to fix it after the L-shaped plate 2011 has been replaced and rotated.

The surface of the movable slip ring 2042 is slidably connected to the inner side of the movable groove 2031, and the surface of the movable slip ring 2042 is engaged with the movable locking block 2012. By setting the reset assembly 204, the reset spring 2041 can reset the movement of the movable slip ring 2042, so that the loading assembly 205 can drive the cutter head assembly 206 to reset.
