Laparoscope MDOF (multiple degrees of freedom) supporting device

Abstract

The invention relates to a laparoscope MDOF (multiple degrees of freedom) supporting device which comprises a bracket, a lifting mechanism, a beam, a second locking mechanism, a fixture base, a connecting shaft, a third locking mechanism and a fixture; the lifting mechanism is mounted on the bracket; one end of the beam is rotatably mounted in a first shaft hole; the connecting shaft is rotatably mounted in a third shaft hole, and the fixture base is connected with the outer end of the connecting shaft; the fixture is mounted on the fixture base; the fixture comprises two arc clamping pieces, and a plurality of balls capable of rotating along a vertical direction are arranged on the inner lateral surfaces of the arc clamping pieces. The height of the fixture is regulated by the lifting mechanism, the beam is rotated to enable a laparoscope to swing front and back, the fixture base is rotated to enable the laparoscope to swing left and right, and by arranging the balls on the inner lateral surfaces of the two arc clamping pieces, the laparoscope can be freely rotated, so that supporting, lifting, left-and-right swinging, front-and-back swinging and rotation of the laparoscope are implemented; labor is saved, the laparoscope MDOF supporting device is more convenient and flexible to operate, potential safety hazards caused by vibration, non-tacit matching and the like are avoided, and safety is higher.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a laparoscopic multi-degree-of-freedom supporting device. Background technique [0002] Laparoscope is similar to electronic gastroscope, it is a kind of instrument with miniature camera, laparoscopic surgery is the operation using laparoscope and related instruments: use cold light source to provide illumination, insert laparoscopic lens (diameter 3 ~ 10mm) In the abdominal cavity, the image captured by the laparoscopic lens is transmitted to the post-stage signal processing system through the optical fiber by using digital camera technology, and displayed on a special monitor in real time. Then the doctor analyzes and judges the patient's condition through the images of different angles of the patient's organs displayed on the monitor screen, and uses special laparoscopic instruments to perform the operation. [0003] Laparoscopic technique is a kind of minimally invasive surgery, which...

Problems solved by technology

[0004] The laparoscope is provided with at least one camera at the top of the outer end, and the camera is connected to the computer through a cable. Both the camera and the cable have a certain weight and will eventually be carried on the laparoscope lens. Therefore, during laparoscopic surgery, the laparoscope needs to be adjusted. However, in order to obtain all-round and certain detailed images during laparoscopic surgery, it is required that the laparoscope must be able to lift, swing left and right, swing back and forth, and rotate, while the general support and clamping mechanism cannot meet the above operating requirements. Therefore, at present, it is necessary to add a medical staff to support the laparoscope, which increases manpower. In addition, there are certain safety hazards in laparoscopic surgery due to factors such as vibration and incoordination of manual support.
