Joint rotation structure and anastomat with structure

Abstract

The invention discloses a joint rotation structure which is used for achieving follow-up motions of an abdominal cavity anastomat. The structure comprises a trigger unit used for achieving first-angle rotation, a first transmission unit used for converting first-angle rotation generated by the triggering unit into first translation, a second transmission unit used for converting first translation into second-angle rotation, and an execution unit used for converting second-angle rotation of the second transmission unit into third-angle rotation corresponding to the first-angle rotation. Thus, the execution unit of the anastomat can be bent and steered by means of the joint rotation structure, the intermittent angle adjusting mode of the joint rotation structure is changed into a continuous angle stepless rotation mode, precision and application range of operating instruments are greatly improved, and requirements of required angles are met on the occasions where the operation environment is strict, operation difficulty is high and operation precision requirements are high.

Description

technical field [0001] The invention relates to the field of staplers, in particular to a joint rotation structure and a stapler with the structure. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable for tightness, especially its fast suturing and easy operation. And few side effects and surgical complications and other advantages, but also make the past unresectable tumor surgery can be symptomatic resection, very popular and respected by clinical surgeons at home and abroad. The main working principle of the stapler is to use titanium nails to separate or anastomose tissues, similar to a stapler. [0003] Since the front end of the stapler is usually a straight rod, the straight rod usually cannot match and anastomose the lesions well. In order to adapt t...

AI Technical Summary

Problems solved by technology

[0003] Since the front end of the stapler is usually a straight rod, the straight rod usually cannot match and anastomose the lesions well. In order to adapt to more application environments, in order to achieve limited space and limited angle under the condition of limited operation space and angle The suturing process in the surgical environment, so it is necessary to design a rotating structure so that the front rod structure of the stapler can be bent
