Problems solved by technology

However, it brings a series of difficulties to the doctor's operation:
[0003] 1) Due to the limitation of small holes on the body surface, the degrees of freedom of surgical tools are limited to 4 (excluding opening and closing), and the flexibility of doctors' operations is reduced;
[0004] 2) The operation presents a leverage effect, and the movement of the doctor's hand is opposite to the movement of the end of the surgical tool, resulting in incoordination of the eyes and hands;
[0005] 3) The doctor obtains the surgical scene information through the two-dimensional image on the monitor, which lacks the feeling in the depth direction;
[0006] 4) The shaking of the doctor's hand may be amplified by the slender surgical tools, which affects the quality of the operation
Due to the existence of these unfavorable factors, this advanced surgical method is only applied in relatively simple operations
[0007] Existing minimally invasive surgical devices are expensive; in addition, common diseases in different countries are not equal, so the surgical tools provided by existing minimally invasive surgery cannot meet the needs of patients in different regions

Embodiment Construction

[0015] As shown in the figure, the present invention includes a master operating terminal, a slave operating terminal, a control system, and a display device, and the control system is connected to the master operating end, the slave operating end, the control system, and the display device respectively.

[0016] The slave operating end includes a surgical tool operating arm and an endoscope operating arm.

[0017] The display device is a liquid crystal display.

[0018] The control system is the core of the surgical robot to achieve the predetermined function. During the surgical operation, it needs to complete at least two functions: 1) collect the input information of the doctor on the main console, and output the information after relevant processing, so as to realize the control of the robot from The control of the manipulator; 2) processing the manual intervention information in the operation process. For a specific minimally invasive robot, the control system also need...

Abstract

The invention belongs to the technical field of medical instruments, particularly relates to a robot for assisting minimally invasive laparoscopic surgery and provides a robot for assisting minimally invasive laparoscopic surgery, which has high information positioning accuracy and excellent universality. The robot comprises a main operation end, a slave operation end, a control system and a display device, and has the structural point that the control system is connected with the main operation end, the slave operation end and the display device respectively.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a robot for assisting abdominal minimally invasive surgery. Background technique [0002] When performing minimally invasive surgery, the doctor inserts long and thin surgical tools into the patient's body through a tiny incision on the patient's body surface for surgical operations. Compared with traditional open surgery, this surgical method can reduce the trauma caused by the operation to the patient and shorten the recovery time. However, it brings a series of difficulties to the doctor's operation: [0003] 1) Due to the limitation of small holes on the body surface, the degrees of freedom of surgical tools are limited to 4 (excluding opening and closing), and the flexibility of doctors' operations is reduced; [0004] 2) The operation presents a leverage effect, and the movement of the doctor's hand is opposite to the movement of the end of the surgical tool, resu...
