Description

[0001] TROCAR APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical apparatus, and more particularly, to a trocar apparatus used for securing a delivery channel of a surgical instrument.

Generally, in the case of conventional open incision surgery for patient treatment, since the incision site is large and the amount of bleeding occurring during surgery is large, the patient recovery after surgery is slow and a large scar remains after surgery, Recently, new surgical techniques such as Minimal Invasive Surgery (MIS) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) have been developed to overcome the disadvantages of such open incision surgery.

Minimally invasive surgery is a surgical technique that uses a thin and long surgical tool specially designed to minimize the incision required for surgery, so that the minimally invasive surgery is performed on the patient's body. The scarless surgery is performed on the patient's body In order to transfer the surgical tool, a surgical tool is inserted through a hole (esophagus, anus, vagina, etc.) naturally present in the human body without cutting the body of the patient, Technique. These minimally invasive and non-scarring procedures require fewer incisions for the procedure, and the amount of bleeding during operation is considerably less than that of the open surgery. Therefore, there is an advantage that the patient's recovery period is fast and the scarring is small. The number of procedures is increasing significantly.

In order to perform gynecologic cancer through minimally invasive surgery or non-scar operation, a trocar is needed to secure free movement and movement of surgical instruments through the quality of the patient.

However, there is no dedicated trocar to secure the free space and activity space of the surgical tool through the quality of the current patient, and when the general trocar used for the conventional laparoscopic procedure is inserted into the patient's vagina, It is not possible to perform stable operation because the trocar is not fixed enough. US Pat. No. 5,697,946 discloses a laparoscopic surgical tool for attaching a balloon to a trocar and inserting the trocar into the tissue to expand the balloon to fix the trocar to the biotissue in the "METHOD AND APPARATUS FOR ANCHORING LAPAROSCOPIC INSTRUMENTS" In some cases, fixation of the trocar in the vagina is possible. However, in this case, when the user inserts the trocar needle through the vagina of the patient, a separate device for lifting the uterus up and securing the operative space in the abdominal cavity is required. This causes inconvenience of the operator In addition, there is a problem that the balloon attached to the trocar can be damaged by a surgical device that raises the uterus.
