Multifunctional abdominal-cavity minimally invasive surgery tool

Abstract

The invention provides a multifunctional abdominal-cavity minimally invasive surgery tool. The multifunctional abdominal-cavity minimally invasive surgery tool is characterized in that a left blade and a right blade are symmetrical in shape and are arranged in a crossed manner, and a connecting shaft connects an end cap, the left blade and the right blade to an actuator; a first steel wire ring and a second steel wire ring are wound in winding grooves of the left blade and the right blade and can drive the left blade and the right blade to rotate around the connecting shaft; fixing holes for surgery stringing are formed at the front ends of the left blade and the right blade, and an edge is arranged at the center; clamping teeth are arranged on the corresponding inner sides of the front ends of the left blade and the right blade, and the outer sides of the front ends are expanding faces; the front end of the left blade is provided with an electrocautery electrode, and the rear end of the left blade is provided with an electrical joint connected with the electrocautery electrode; a liquid sucking hole is formed at the front end of the right blade, a the rear end of the right blade is provided with a liquid sucking joint communicated with the liquid sucking hole; a CCD (charge coupled device) and a plurality of LEDs are arranged on the end cap. The multifunctional abdominal-cavity minimally invasive surgery tool integrates multiple functions of clamping, cutting, expanding, sucking / blowing, electrocauterizing, and real-time observing, structure is simple, cost is low, and the requirements on accuracy, flexibility, stability and security of the surgery can be met.

Description

technical field [0001] The invention relates to a surgical medical device, in particular to a multifunctional abdominal cavity minimally invasive surgical tool, which belongs to the technical field of medical devices. Background technique [0002] Since the 1990s, with the rapid development of surgical robot technology, micro-instruments for surgical robots with multiple functions are one of the most important core components in surgical robots. Surgical robot micro-instruments are used for minimally invasive surgery. During the operation, the micro-instruments at the end of the surgical robot enter the human body to perform operations such as cutting, clamping and suturing human tissues. At present, domestic robots that meet higher requirements include the "Miaoshou" series of robots mainly developed by Tianjin University; foreign relatively mature surgical robot systems include Da Vinci surgical system, ZEUS robotic surgical system and AESOP robotic system, but their syste...

Problems solved by technology

The disadvantage of this structure is that the structure of the system is complex and the function is single, it is difficult to perform precise surgery under a small surgical wound, the replacement of the knife and the maintenance procedure are more complicated, and it is difficult to realize the actual application

[0005] The above two instruments for surgical robots have common defects. First of all, they have a single function, and only one function can be realized at a time. To perform another surgical operation, the tools or knives at the end must be replaced, otherwise multiple surgical robots must be used together. operation, thus leaving multiple wounds on the patient's body; secondly, they all have complex structures, resulting in unstable operation and high cost
