Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] see Figure 1-3 , a series motion mechanism 10 provided by the first embodiment of the present invention is used to control the movement of surgical instruments, and it includes a control handle 20, a wrist ring 30 and a series joint 40. Double joint rotation mechanism, and the rotation axes of the two joints are vertical, the control handle 20 is connected with the wrist ring 30 through the series joint 40, which is used to decompose the motion state of the control handle 20, and convert it into the joint motion of the series joint 40 as a control source use. That is, by applying an exter...

Abstract

The invention relates to a series motion mechanism, comprising a wrist ring attached to the wrist; a control handle; a series joint, the series joint is a double joint in series, and the axes of rotation axes of the two joints are vertical, and the control handle passes through the series joint The joint is connected with the wrist ring, and is used for decomposing and converting the motion state of the control handle into the joint motion of the serial joint. The present invention also provides a surgical instrument control mechanism and a hand-held surgical device. The series motion mechanism, surgical instrument control mechanism and hand-held surgical device provided by the present invention can drive the deflection of the surgical instrument through the movement of the wrist, reducing the workload on the doctor's arm .

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a serial motion mechanism, a surgical instrument control mechanism and a hand-held surgical device. 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] In the existing minimally invasive surgery, the gap is opened by poking a card at the place where the patient needs surgery, and then the hand-held surgical instrument is inserted into the gap to perform the operation. During the operation, when the direction of the hand-held surgical instrument needs to be adjusted, the doctor usually raises his a...
