Negative pressure suction type ultrasonic scalpel

Abstract

The invention discloses a negative pressure suction type ultrasonic scalpel, and belongs to the technical field of medical instruments. The negative pressure suction type ultrasonic scalpel comprisesa negative pressure suction type ultrasonic scalpel main body, wherein a handle device is arranged below the negative pressure suction type ultrasonic scalpel main body; the handle device comprises amovable plate, a lead screw, a movable frame, a knob, a sliding block, a chute and a handle shell, wherein the movable plate is arranged below the negative pressure suction type ultrasonic scalpel body; the handle shell is arranged below the movable plate; the knob is arranged below the handle shell; the lead screw is arranged above the knob; and the movable frame is mounted on the outer side of the lead screw and located inside the handle shell through threads. According to the negative pressure suction type ultrasonic scalpel, the ultrasonic scalpel can be used for adjusting the position ofthe movable plate by rotating the knob due to the handle device, the total length of the handle device and the relative position of the handle shell are adjusted, the requirements of different users are met, and the adjusting capacity of the ultrasonic knife is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a negative pressure suction type ultrasonic scalpel. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including required computer software. [0003] The prior art has the following problems: 1. Most of the current negative pressure suction ultrasonic scalpels have the problem that the length of the handle cannot be adjusted according to the needs of the user, which causes certain inconvenience and reduces the adjustment ability of the ultrasonic scalpel; 2. Most of the negative pressure suction ultrasonic scalpels have the problem that they cannot be illuminated when needed, thereby reducing the working capacity of the ultrasonic scalpel; 3. Most of the current negative press...

Problems solved by technology

[0003] The prior art has the following problems: 1. Most of the current negative pressure suction ultrasonic scalpels have the problem that the length of the handle cannot be adjusted according to the needs of the user, which causes certain inconvenience and reduces the adjustment ability of the ultrasonic scalpel; 2. Most of the negative pressure suction ultrasonic scalpels have the problem that they cannot be illuminated when needed, thereby reducing the working capacity of the ultrasonic scalpel; 3. Most of the current negative pressure suction ultrasonic scalpels cannot illuminate the tubes on the ultrasonic scalpel when needed. The problem of orderly placement of the tubes on the ultrasonic knife makes the tubes on the ultrasonic knife easy to be scattered and knotted, which reduces the practicability of the ultrasonic knife
