Description

Laparoscopic surgical device {APPARATUS FOR LAPAROSCPOIC SURGERY}

The present invention relates to a laparoscopic surgical device, which can be easily manipulated to perform a rotational motion together with a translational motion for withdrawing an end-effector during surgery, and minimizes contamination by suction during suction and washing during surgery. It's about a device that can do that.

Laparoscopic surgery is a surgical technique in which several small incisions are made in the abdomen and a video camera and various instruments are inserted through these holes into the abdominal cavity. In laparoscopic surgery, compared to traditional open surgery, the size of the incision is small, so the surgical wound is aesthetically pleasing and the pain caused by the wound is much less. In addition, since it shows a fast recovery rate, the hospital stay period is shorter than that of open surgery, and it has the advantage of being able to quickly return to daily life. After the patient is anesthetized, a needle is inserted into the navel area of the patient to create a state of relief (inflating the abdominal cavity by inserting carbon dioxide into the abdominal cavity), through a thin tube). When the camera is inserted through the trocar, the intra-abdominal image is projected on the monitor in front of the operator, and the operator performs the desired operation using an appropriate laparoscopic instrument while looking at the monitor.

To perform surgery, a user, such as a surgeon, introduces working tools through a trocar at the surgical site and manipulates them from outside the abdominal cavity. On the other hand, the surgeon monitors the progress by a monitor that displays an image of the surgical site taken by the laparoscope. Similar endoscopic techniques are used throughout, such as retroperitoneal endoscopy, pelvic endoscopy, arthroscopy, hydrocephalus, sinusoscope, hysteroscopy, nephroscope, cystoscopy, urethoscope, and pyeloscopy.

For laparoscopic surgery, a laparoscopic surgical device capable of performing operations such as incision, hemostasis or suturing of the affected area by being close to the affected area through a narrow hole formed in the skin of the human body is required. The laparoscopic surgical device may include an end effector (or may be expressed as a 'tip') for performing surgery such as incision, hemostasis, or suturing for the affected part at one end. The end effector may be formed in various shapes, such as a tongs shape or a hook shape, depending on the type of treatment. An electric potential may be applied to the end effector of the laparoscopic surgical device for ease of operation on the affected area. A method of applying a potential to the end-effector includes a method of applying a unipolar potential and a method of applying potentials of different polarities to a pair of tips, respectively. A method of applying a single-pole potential to the end-effector is to attach a counter-pole to the patient's skin and apply only one potential to allow current to flow through the patient's entire body. The method of applying potentials of different polarities to one end-effector is to apply different potentials to the end-effector consisting of a pair of mutually insulated pairs so that current flows only in the necessary parts, which puts a small burden on the patient's body and makes the procedure easier. way to do it

In a surgical procedure, it is often necessary to inject a sterile solution into the surgical site and to drain the washing solution from the surgical site or to drain it outside the body. Therefore, a laparoscopic surgical device capable of simultaneously performing suction/washing functions and a laparoscopic surgical device capable of performing hemostasis and the like by applying an electric potential to the end effector as described above have been developed.

However, in the case of conventional laparoscopic surgical devices, rotation of the end effector is possible by rotating the inner shaft through a drive handle, etc. during the operation, but translational motion cannot be performed simultaneously with rotation. It has a problem that rotation operation cannot be performed with potential application because rotation operation cannot be performed in the state of being in close contact with it. In addition, there is a problem in that suction water or cleaning solution passes through one cylinder during the suction and cleaning process, and the suction water mixes with the cleaning solution to contaminate the cleaning solution.

In order to solve this problem, an object of the present invention is to provide a laparoscopic surgical device capable of simultaneously performing rotation and translation while applying an electric potential and minimizing contamination in the suction washing process.

In the laparoscopic surgical device of the present invention for solving these problems, an end-effector and a through-hole are formed, an end-effector is coupled to one end, and an internal shaft unit and a through-hole are formed at the other end to be rotatably coupled with the body cylinder. The shaft unit is inserted in a penetrating form, and is provided as a guide groove in the outer shaft unit and the inner shaft unit having a drive handle, and is provided as a guide rail in the outer shaft unit, or is provided as a guide rail in the inner shaft unit and the outer shaft unit Link means provided as a guide groove in the guide groove to guide the translational movement of the outer shaft unit and to rotate the inner shaft unit together according to the rotational movement of the outer shaft unit through the drive handle; The body cylinder, a conductive member provided inside the body cylinder and penetrating through one surface of the body cylinder, one end in contact with the internal shaft unit, passing through one side of the body cylinder, and the other end being connected to the power supply unit directly or through a conductive elastic body, and a power supply unit. This can be achieved by configuring

Using the present invention, it is possible to simultaneously perform a rotational movement while performing a translational movement to withdraw the end-effector during the surgical procedure, enabling manipulation for various purposes. In this case, measures such as hemostasis can be appropriately performed while performing translational or rotational manipulations.

In addition, a suction cylinder (Suction) partition pipe is additionally provided so that the suction material flowing in from the outside through the other end of the partition pipe passes through the suction cylinder partition pipe and is directly sucked through the body cylinder through hole (Suction). ) flows into the cylinder, so it is possible to minimize the contamination of the cleaning solution during the suction process.
