Problems solved by technology

At present, manual micro-manipulators are mainly used in domestic abdominal surgery, but the current micro-manipulators have a simple structure and only have the functions of clamping and stretching. In this way, it is not convenient for doctors to use during minimally invasive surgery, which will affect the stability of the operation. and the grasp of accuracy have a certain impact

Embodiment 1

[0026] refer to Figure 1-3 , a manual three-degree-of-freedom micromanipulator for minimally invasive surgery, including a fixed block 2 and a connecting frame 5, the top of the inner wall on both sides of the connecting frame 5 is rotatably connected to the same horizontally placed rotating shaft 10, and the outer wall of the rotating shaft 10 is covered Connecting block 4 is connected, the outer wall of the top of connecting block 4 is fixedly connected with the outer wall of the bottom of fixed block 2, the bottom of the inner wall on both sides of connecting frame 5 is connected with the first connecting shaft 7 placed horizontally, and the outer wall of the first connecting shaft 7 is covered with Connected with driving gear 6, connecting block 4 bottom outer wall is equipped with driven gear 9, and driven gear 9 and driving gear 6 are meshed.

[0027] In the present invention, a rectangular groove is formed on the outer wall of the top of the fixed block 2, and the inne...

Embodiment 2

[0030] refer to Figure 1-4 , a manual three-degree-of-freedom micromanipulator for minimally invasive surgery, which also includes a circular limiting groove on the top outer wall of the circular column 14, and equidistantly distributed limiting rods 16 installed on the outer wall of the bottom of the connecting frame 5, the limiting rods 16 The circular outer wall is slidingly connected to the inner wall of the circular limiting groove, the stepper motor 15 is connected to a switch through a wire, and the switch is connected to a power supply through a wire.

[0031] Working principle: Compared with Example 1, by providing a circular column 14, a stepping motor 15 and a limit rod 16, the manipulator can be rotated, which improves the scope of use, and the limit rod 16 is in the circular limit groove Internal sliding for improved rotational stability.

Abstract

The invention discloses a manual three-freedom-degree micro manipulator for minimally invasive surgery. The manual three-freedom-degree micro manipulator for minimally invasive surgery comprises a fixing block and a connecting frame, wherein the same rotating shaft which is horizontally arranged is rotatably connected to the tops of the inner walls on two sides of the connecting frame; a connecting block is connected to the outer wall of the periphery of the rotating shaft in a sleeving manner; the outer wall of the top of the connecting block is fixedly connected with the outer wall of the bottom of the fixing block; the same first connecting shaft which is horizontally arranged is rotatably connected to the bottoms of the inner walls on two sides of the connecting frame; a driving gear is connected to the periphery outer wall of the first connecting shaft in a sleeving manner; a driven gear is mounted on the outer wall of the bottom of the connecting block; and the driven gear is meshed with the driving gear. According to the manual three-freedom-degree micro manipulator for minimally invasive surgery disclosed by the invention, the connecting block, the driven gear, the connecting frame and the driving gear are arranged, so that the fixing block on the connecting block can be driven to move in a front and rear manner, the moving range of the manipulator is enlarged, and theworking efficiency is improved; and the connecting rod is arranged, so that rotation of the fixing block on the connecting block can be more stable, and the using safety of the manipulator is improved.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manual three-degree-of-freedom micro manipulator for minimally invasive surgery. Background technique [0002] Minimally invasive surgery, as the name suggests, is a minimally invasive surgery. Refers to the use of laparoscopy, thoracoscopic and other modern medical equipment and related equipment for surgery. The advantages of minimally invasive surgery are small trauma, light pain, and quick recovery are the dreams of every patient who needs surgery. Minimally invasive surgery makes this dream a reality. [0003] It uses advanced modern medical instruments and related equipment to perform surgery with minimal trauma and can achieve excellent therapeutic effects. At present, manual micro-manipulators are mainly used in domestic abdominal surgery, but the current micro-manipulators have a simple structure and only have the functions of clamping and stretching. In this wa...
