Surgical forceps device with improved grip {Forcep Device for Surgical Operation}

The present invention relates to a surgical forceps device with improved grip, and more particularly, to allow easy control of the grip handle in a locked and unlocked state through a hook device, and to freely rotate the forceps at any angle. , The power switch operates only when the grip handle is pulled to prevent user safety accidents when using the device, thereby increasing the safety of the product as a whole. A new type of surgical forceps device with an improved grip feeling as the handle part of the body is ergonomically designed. It is about.

In general, laparoscopic surgery is a surgical method in which a video camera and various instruments are inserted into several small holes (incisions) of 0.5 to 1.5 cm in size, unlike open surgery, which is performed by opening a large incision in the abdomen. It is also called 'minimally invasive surgery'. Compared to traditional open surgery, laparoscopic surgery has a small incision size from the patient's point of view, so the wound remains small and looks good cosmetically, and the pain caused by the wound is much less. In addition, since it shows a fast recovery rate, the hospitalization period is shorter than that of open surgery, and it has the advantage of being able to return to daily life quickly.

In the case of conventional laparoscopic surgery, after the patient is anesthetized, a needle is inserted into the patient's navel to create a state of relief (inflating the abdominal cavity by injecting carbon dioxide into the abdominal cavity), and a trocar is pierced as many times as necessary in an appropriate position.

When a camera is inserted through the trocar, intra-abdominal images are projected on a monitor in front of the operator, and the operator performs a desired procedure using appropriate laparoscopic surgical instruments while watching the monitor.

As described above, since the operator performs surgery through a camera inserted into a small incision, the field of view is limited and the movable range of surgical instruments is limited. Particularly, in laparoscopic surgery, clipping for ligation or dissection of blood vessels may be necessary. In this case, conventional laparoscopic surgical instruments cannot perform simultaneous clipping during surgery, so surgical instruments must be alternately used with external assistance. There was a hassle to do. Due to the nature of laparoscopic surgery in which surgery is performed through a small incision, the repetitive replacement of such surgical instruments may increase the operation time and become a factor in complicating the surgical procedure.

In addition, the method using the clip is simple and easy to operate, and it is removed at the end of the operation, so there is no tissue damage, so it is helpful for wound circumcision. There was a problem in that it was difficult to manipulate the timing of ligation to the site.

According to Korean Patent Registration No. 10-2042684 (registration date: November 04, 2019), referring to FIGS. 14 and 15, a conventional laparoscopic surgical instrument includes a rod part 130 and a body part provided on one side of the rod part. (110) and a working member provided on the other side of the body portion provided in the rod portion. The rod part 130 may be provided with a length suitable for the operator according to the surgical environment, and the working member may be provided at one end of the rod part where surgery is performed, and the body part 110 is the rod opposite to the working member. It may be provided at the other end of the part. On the other hand, the work member includes a holder 151 on which a surgical clip used for ligating blood vessels is mounted and a blood vessel support member 153 provided on both sides of the holder to support or widen blood vessels during surgery. could include more.

On the other hand, the body portion 110 includes a gripping member 131 gripped by a user, a hinge coupling member 133 hinged rotatably to the gripping member 131, and a trigger 135 provided on one side of the body portion. ), and the gripping member and the pivoting member will have a hole formed to the extent that the operator's finger enters.

The above-described conventional laparoscopic surgical instrument is fixed to the user by the gripping member formed in the body and the hinge coupling member 133, and as the hinge coupling member 133 rotates, the blood vessel support member 153 provided to the work member ) will perform a sideways widening operation to support the blood vessels or to separate the blood vessels from each other. In an operating mode, the blood vessel support member 153 may be opened at one point (FIG. 17) or may be opened in parallel with each other (FIG. 16).

However, as described above, the conventional surgical instrument has a problem in that it is difficult to operate the instrument with one hand.

In addition, since there is no temporary locking device function, it is difficult to release the pod device and proceed with the gripping process again when changing the surgical site, which is inconvenient in use.

In addition, there is a risk that an electrical safety accident may occur because there is no countermeasure against electrical shock concerns.

The present invention has been made to solve the problems of the prior art, so that the grip handle can be easily controlled in the locking and unlocking states through the hook device with only one hand, and the rotation of the forceps is freely performed at any angle, , The power switch operates only when the grip handle is pulled to prevent user safety accidents when using the device, thereby increasing the safety of the product as a whole. It is to provide a forceps device for use.
