Description

Laparoscopic surgery device

The present invention relates to a laparoscopic surgical instrument, and more particularly, to a laparoscopic surgical instrument having a suction function or a wash water supply function by selectively pushing or pulling up / And 2) it is possible to secure the surgical field by discharging the harmful smoke generated by the electrocautery during the operation to the outside of the abdominal cavity at the same time as the electrocautery, and 3) to protect the medical person and the patient from the smoke causing the cancer And 4) a laparoscopic surgical instrument having various functions such as shortening the operation time and improving the convenience of operation.

Unlike conventional open surgery, laparoscopic surgery is a method of inserting a laparoscope to look through the abdominal cavity and examine the inside of the abdominal cavity.

For reference, laparoscopy refers to an endoscope for the examination and treatment of abdominal cavity and abdominal cavity.

Such laparoscopic surgery can be applied to the resection of various organs, and the postoperative pain is weak and the risk of complications is lower than that of the open surgery.

In addition, laparoscopic surgery has recently been widely used because it has the advantage of alleviating the scar of the surgical site.

There are various types of laparoscopic surgical instruments for laparoscopic surgery, such as clamping devices, cutting devices, suction devices, and water supply devices.

Some of these instruments have single functions, or some have multiple functions. The surgeon performs laparoscopic surgery using various instruments.

On the other hand, among various surgical instruments, in particular, in the case of a laparoscopic surgical instrument having a suction function or a wash water supply function, a button for performing a corresponding function must be pressed for operation of the instrument.

That is, the suction function and the wash water supply function can be provided by pressing the button.

As described above, since the conventional laparoscopic surgical instrument provides a suction function or a washing water supply function by pressing the button, the operation may be somewhat cumbersome or inconvenient depending on the operator, which makes the operation somewhat uncomfortable and difficult .

In addition, during laparoscopic surgery, large amounts of smoke are generated in the process of cutting the tissue by using electricity, and it is difficult to obtain the visual field during surgery, so the operation is stopped and the air is discharged and then the air is returned into the abdominal cavity And the smoke from the surgical field has a problem that can cause cancer in the future for the medical personnel and patients in the same space.

The memory 182 (MEMORY) is connected to the central processing unit 181. The memory 182 may be a computer-readable recording medium and may be located locally or remotely and may be readily accessed, for example, as a random access memory (RAM), read-only memory (ROM), floppy disk, hard disk, It may be at least one or more possible memories.

The support circuit 183 (SUPPORT CIRCUIT) is coupled with the central processing unit 181 to support the typical operation of the processor. The support circuit 183 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

In this embodiment, the controller 180 controls the operation of the suction module 171 and the wash water supply module 172 based on the up / down operation of the up / down sliding lever 145, A series of processes, and the like may be stored in the memory 182. Typically, a software routine may be stored in the memory 182. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

The operation of the laparoscopic surgical instrument 100 having such a configuration will be described below.

In the initial state of Fig. 5, the up / down sliding lever 145 is pushed up as shown in Fig. Thus, the main supply line 120 and the wash water supply line 132 communicate with each other to supply the wash water through the pipe-type shaft 150.

When suction is required, in the initial state of Fig. 5, the up / down sliding lever 145 is pulled down as shown in Fig. Thus, the main supply line 120 and the suction supply line 131 communicate with each other to form a suction through the pipe-type shaft 150.

According to the present embodiment having the structure and function as described above, it is possible to selectively provide a suction function or a washing water supply function by pushing up or pulling down operation much easier than the conventional pressing operation In addition, since the smoke generated in the electrocautery can be removed from the abdominal cavity while being operated, the convenience of operation can be improved.
