Problems solved by technology

[0003] In tumor surgery, surgical robots have broad application prospects, and can accurately and minimally invasively remove tumors and perform other operations. The end of the existing tumor surgery is usually equipped with an upper jaw and a lower jaw. way to achieve, for example Image 6 The upper and lower jaws, on the one hand, will cause the upper and lower jaws to have tail ends, the parts are relatively large, and it is not easy to operate; on the other hand, the way of pulling makes the angle of the upper and lower jaws change sharply, which is not easy to control

Embodiment 1

[0032] Embodiment 1: This embodiment discloses a rotatable part of a tumor surgery robot, which is fixedly connected with the surgical instrument, specifically such as figure 1 As shown, the surgical instrument includes a driving member 3, and the rotating member 4 fixes the driving member to control the surgical instrument to rotate in multiple angular directions.

[0033] In a specific embodiment, such as figure 2 As shown, the rotating part 4 includes a fixed part 43, a first rotating part 41 and a second rotating part 42. Such as Figure 7 As shown, the fixing piece is connected with a connecting piece 5, and the connecting piece is connected with the fixing piece and the mechanical arm 6. In a further embodiment, the robot arm includes a first robot arm 61, a second robot arm 62, a third robot arm 63, and a fourth robot arm 64, and the robot arms are connected to each other to provide different degrees of freedom.

[0034] In a further embodiment, such as figure 2 As shown,...

Embodiment 2

[0051] This embodiment discloses a surgical instrument, which can be installed on the rotating part and the mechanical arm in embodiment 1 for use by a surgical robot. The surgical instrument includes an executive part, a long tube and a driving part. The part is connected to the long tube, and the long tube is connected to the driving part. The driving part drives the execution part through the long tube to contact the human tissue and realize the operation instruction.

[0052] Such as Figure 8 As shown, the actuator includes an upper jaw 71 and a lower jaw 72. The upper jaw and lower jaw are hinged. The upper and lower jaws can be rotated relative to the hinge to control the opening and closing of the upper and lower jaws. The opening and closing of the upper and lower jaws implement surgical instructions, such as electrocoagulation. Instructions, clamping instructions, etc., the upper and lower jaws are provided with sliding grooves 711;

[0053] Connecting head 74, the upper ...

Abstract

The invention discloses an operation apparatus of a tumor operation robot, and belongs to the field of medical care apparatuses. The operation apparatus comprises an executing piece, a long pipe and adriving piece, wherein the executing piece is connected with the long pipe; the long pipe is connected with the driving piece; the driving piece is used for driving the executing piece by the long pipe to be in contact with the human body tissue so as to realize operation commands; the executing piece comprises an upper jaw, a lower jaw, a connector and a push rod, wherein the upper jaw and the lower jaw are hinged at the connector; the connector is fixedly connected with the long pipe; the long pipe is used for fixing the upper jaw and the lower jaw through the connector; the near end of thepush rod is connected with the driving piece; the push rod is driven by the driving piece; two pushing arms which are mutually in parallel are arranged at the far end of the push rod; the driving piece is used for driving the push rod to further drive the push arms to move along sliding grooves; and the pushing arms control the opening and the closing of the upper jaw and the lower jaw along thesliding grooves to realize the operation commands.

Description

Technical field [0001] The invention relates to the field of medical equipment. Background technique [0002] The robotic surgery system is a complex integrating a number of modern high-tech methods. It has a wide range of uses and has a large number of clinical applications in surgery. Surgeons can operate machines away from the operating table to perform operations. It is completely different from traditional surgical concepts. It is a well-deserved revolutionary surgical tool in the field of minimally invasive surgery in the world. On April 4, 2014, the Third Xiangya Hospital of Central South University took the lead in China Domestic surgical robot for gastric perforation repair and appendectomy. [0003] In tumor surgery, surgical robots have a wide range of applications. They can accurately and minimally invasively remove tumors and perform other operations. Existing tumor operations usually have an upper jaw and a lower jaw at the end. The upper and lower jaws are opened an...
