Performing shearing, clamping, suturing, etc. 'However, all the incision actions are harmful to human tissue'. Considering the health recovery of the patient and the future quality of life, the wound is naturally smaller. The better. Nowadays, the medical profession has developed a single-cut singular minimally invasive surgery (5) sand incision laparoscopic surgery (SILS), which is to cut a tiny opening in the body of the patient and set a trocar at the opening. Then, more than one surgical instrument is used to extend the human body through the puncture (4) through the puncture. The medical staff performs the operation in the body of the patient by means of an instrument disposed at one end of the elongated shaft. In this way, the length of the surgical wound of the patient can be only the length of the traditional surgery - it can reduce the risk of infection, reduce the amount of gold during surgery, reduce the pain during recovery, and avoid The bleeding after the operation is more delicious and quick recovery, and the wound after recovery is more beautiful. However, during the minimally invasive surgery described, 'because medical personnel usually use multiple surgical instruments at the same time' it is likely that there will be a large number of rods swinging relative to the puncturing device, although the puncturing device is available for these Surgical instruments _ 3 M425636 is set apart, but due to poor vision during surgery, and many people may use different surgical instruments at the same time, it is easy to operate the surgical instruments into the body of the patient. Collision with each other in the process is not only conducive to the smooth progress of the operation, but also poses a huge risk to the life safety of the patient. [New content] ▲ In view of the above-mentioned shortcomings, the main purpose of this creation is to provide a surgical instrument that can control the bending angle of the user to avoid collision problems, thereby improving the safety of the operation. "To achieve the above objectives" The surgical instruments provided by this creation. a handle; the outer rod body is provided with a body body and a mounting end portion from the grip body, the body portion and the mounting end hole; the T body = the knife f has two rope body perforations and - located at the end of the two-wire body wearing the '-rope body, is worn on the body of the outer rod body, the installation end rope:: the hole 'and the rope body has - located in the body, the installation is corrected The body is worn in the axial movement of the outer body: when the inner body of the dry body t of the inner body of the sea is relatively opposed to the outer rod, the inner rod body will be bent and the force end is abutted The bend of the cord body provides a bendable portion of the present invention that exhibits a curved age mechanism to control the curved arrangement of the inner shaft relative to the outer portion to include a drive curve. The movement of the x buckle body, thereby changing the curved portion of the curved body, is caused by: the inner rod body is axially moved to make the outer rod and the mounting end portion of the outer rod body is opposite to the needle thread or the like: The second patient suffers from movement within the body. Therefore, when most of the U's U are sick, the mobile phone society #钱 simultaneously protrudes into the body of the patient. Moreover, by controlling the internal degree, the distance of movement can control the angle of the swing of the ampoule to move very flexibly. Such a water ^ the safety of minimally invasive surgery can improve the operation === but can improve the detailed structure of the flexible surgery (4) provided by this creation, and describe the method of the installation.
