Medical surgical mechanical arm and use method thereof

Abstract

The invention discloses a medical surgical mechanical arm. The medical surgical mechanical arm comprises a locking driving mechanism, a universal mechanical arm, a locking driving mechanism shell, an instrument clamp assembly and a fixing clamp assembly; the locking driving mechanism, the universal mechanical arm and the instrument clamp assembly are connected in sequence; the locking driving mechanism shell is arranged on the periphery of the locking driving mechanism; the universal mechanical arm comprises a universal arm seat, a universal arm sheath, a universal mechanical arm joint structure and a steel wire inhaul cable; the steel wire inhaul cable is connected with the locking driving mechanism, and the other end of the steel wire inhaul cable penetrates through the universal mechanical arm joint structure; the universal arm sheath is arranged on the periphery of the universal arm seat and is arranged on the periphery of the tail part of the universal mechanical arm joint structure; the locking driving mechanism comprises a working cylinder and a lever structure; and the working cylinder is connected with the steel wire inhaul cable through the lever structure. The medical surgical mechanical arm has the advantages that a stable structure can be formed to keep medical instruments needed in an operation stable for a long time, and meanwhile, the operation space of the operation is expanded to the maximum extent. The invention further discloses a use method of the medical surgical mechanical arm.

Description

technical field [0001] The invention relates to a medical operation mechanical arm. The invention also relates to a method of using the medical surgical robot arm. Background technique [0002] In the existing operation process, it is often necessary to keep a certain medical device stable for a long time during the operation to keep the surgical field of view stable and clear. At this time, a person is usually assigned to hold the medical device and maintain a fixed posture during the operation to achieve the purpose. However, this method is affected by people's attention, physical strength, etc., and cannot maintain a stable state for a long time. It is often necessary to adjust the position and angle of the hand-held medical device, which causes the deviation of the surgical field of view and affects the smooth progress of the operation. ; Because the people who hold the medical instruments occupy the space on the side of the operating table, the operating space is affe...

Problems solved by technology

However, this method is affected by people's attention, physical strength, etc., and cannot maintain a stable state for a long time. It is often necessary to adjust the position and angle of the hand-held medical device, which causes the deviation of the surgical field of view and affects the smooth progress of the operation. ; Since people holding medical instruments occupy the space beside the operating table, the operating space is affected and the chance of surgical infection is also increased

[0003] The existing medical surgical manipulators have the following disadvantages: (1) The structure is complex and the manufacturing cost is high; (2) The segments are too long and the flexibility is poor
