Description

Surgical instrument and endoscope manipulator {Endoscope manipulator for minimal invasive surgical operation}

The present invention relates to a surgical instrument and an endoscope adjusting device, and more particularly, to a surgical instrument and an endoscope adjusting device capable of vertical, left and right rotation and forward/backward transfer of the surgical instrument and endoscope, and capable of miniaturization and weight reduction.

In general, various medical instruments and scopes, fixed arms, etc. necessary for completing surgery in conventional medical procedures and surgical instruments are provided.

These medical instruments are strategically placed around the surgery to allow visualization of the surgeon and use of the instruments to access the surgical target.

Although this surgical arrangement has been established as a very effective and excellent standard for minimal surgery, it has many drawbacks.

Medically, surgery refers to the treatment of diseases by cutting, slitting, or manipulating skin, mucous membranes, or other tissues using surgical instruments. In particular, open surgery in which the skin of the surgical site is incised and opened to treat, mold, or remove the organs therein causes problems such as bleeding, side effects, patient pain, scarring, and the like.

In contrast, minimally invasive surgery (minimally invasive surgery) in which a small insertion hole is drilled instead of incision of the skin, and surgical instruments such as an endoscope, a laparoscope, a surgical instrument, and a microsurgery microscope are inserted through this to perform surgery in the body ( MIS: Minimum Invasive Surgery) is in the spotlight. On the other hand, this minimally invasive surgery may be performed manually by an operating surgeon, but recently, instead of the operator directly manipulating the instrument, a robotic surgery in which a surgical robot is used to precisely manipulate the instrument to perform the surgery has been proposed as an alternative. .

When performing such minimally invasive surgery and scarless surgery, a specially designed endoscopic device is used to secure a view of the surgical site through a minimal body incision. That is, the endoscope apparatus is a medical imaging apparatus for minimally invasive surgery in which a field of view inside a patient's body is not directly secured. Doctors and nurses who perform minimally invasive procedures perform surgery while viewing the image of the treatment site secured through such an endoscope device.

During minimally invasive surgery and scarless surgery, the position of the endoscope and the direction of the field of view must be continuously changed in order to illuminate the changing condition of the surgical site and the movement of the surgical tool as broadly and accurately as possible. In order to adjust the movement of the endoscope throughout the entire period of surgery, an assistant operating manpower other than the surgeon is currently put into the operating room and is in charge of adjusting the movement of the endoscope. However, if a dedicated manpower is separately input to adjust the movement of the endoscope, skilled medical manpower is wasted, and as a result, the total number of procedures is reduced.

In order to solve this problem, recently, some endoscope adjustment devices for adjusting the movement of the endoscope without the need for a separate dedicated manpower have been developed. Most of the endoscope adjustment devices that have been recently developed employ a method of adjusting the movement of the endoscope by using a multi-axis control robot arm by applying robotics technology.

In this way, when the endoscope is adjusted using a robot arm type device, the precise position and angle of the endoscope can be adjusted through the forward-reverse kinematic analysis of the robot arm, but since the entire joint is controlled using a motor, the As the load increases, there is a limit that the size and weight increase. In addition, in some cases, when the joint part of the robot arm is largely moved to adjust the posture of the endoscope, there is a disadvantage in that the activity of the surrounding medical staff is disturbed or restricted.

In particular, in an environment where an accident can occur due to the vibration of the endoscope during manual surgery without a specific fixing device in the place of use, the products are not only complex and bulky in structure, but also reduce the scope of activity of the doctor, and manage and store equipment. It was not easy, and most of the electronic components were included, so it was difficult to obtain permission. In addition, training according to operation control had to be completed, the price was high, and foreign products were mainstream, so there were many restrictions on domestic production.
