Description

The present invention relates to a silicone tape with a needle for endoscopic surgery. More specifically, the present invention relates to a silicone tape with a needle used to pull a luminal organ such as a ureter or a blood vessel or other organs around the surgical site to widen the field of view when performing endoscopic surgery.

In endoscopic surgery (laparoscopic surgery or robot-assisted surgery), generally, a desired number of holes (for example, 4 to 6) of about 5 mm to 12 mm are made without making a large incision in the abdomen, and a trocar is made through the holes. Insert (also called trocar or port) into the abdominal cavity. Next, an endoscope (laparoscope) is inserted from one trocar to display the stomach, large intestine, kidneys, spleen and other organs in the abdominal cavity on a monitor. Then, a forceps with scissors, an electric knife, tweezers, etc. attached to the tip of another trocar is inserted as desired, and the organ and surrounding lymph nodes are excised while monitoring the monitor.

In endoscopic surgery, a method of injecting carbon dioxide (gas) into the abdominal cavity from the trocar to inflate the abdominal cavity and facilitate observation of the inside is adopted. In addition, a method of pulling and lifting the abdominal wall of a patient is also adopted depending on the physique and constitution of the patient, the type of surgery, and the like (see, for example, Patent Documents 1 and 2).

By the way, in endoscopic surgery (laparoscopic surgery), the treatment target site is often hidden under a luminal organ such as a patient's ureter or blood vessel. In this state, it is difficult to see the surgical site, so that the surgical operation cannot be performed smoothly and satisfactorily. In the above cases, conventionally, as shown in FIGS. 13 and 14, a method (conventional technique) of pulling and lifting a target ureter or other luminal organ using silicone tape to widen the field of view is generally used. It has been adopted.

Therefore, the conventional technique will be described with reference to FIGS. 13 and 14. FIG. 13 is a diagram showing the configuration of the silicone tape 5 used by the conventional technique, and FIG. 14 is an explanatory diagram showing a state in which the luminal organ is pulled and lifted by the tape 5.

The silicone tape 5 is composed of a strip-shaped or tubular (tube-shaped) surgical tape made of silicone rubber having a desired length and thickness. In FIG. 14, 4 is the abdomen (cross-sectional view of the abdomen), 40 is the abdominal wall, 41 is the abdominal cavity, 42 is the spine, 43 is a luminal organ such as a ureter in the abdominal cavity, and 44 is through a hole made in the abdominal wall. A desired number of trocars inserted into the abdominal cavity, 45 indicates a forceps inserted from the trocar 44 with an electric knife, scissors, tweezers, or other desired instrument attached to the tip. In addition, only a part of the organs, trocars, forceps, etc. in the abdominal cavity is shown as an example.

In the conventional technique, the silicone tape 5 is inserted into the abdominal cavity 41 through the trocar 44, and the organ is held by winding the tape 5 around an organ such as a target ureter 43. Then, the trocar 44 is pulled out once, the tape 5 is pulled out from the hole, the trocar 44 is reinserted, and the pulled out tape 5 is pulled to pull the organ and lift it. ing. In this case, the trocar 44 is first pulled out, the silicone tape 5 is inserted into the abdominal cavity 41 through the hole, the target organ is held by the tape 5 in the same manner as described above, and the tape 5 is pulled out from the hole. In some cases, the trocar is reinserted and operated in the same manner as described above to lift the organ.

As described above, in the conventional technique, the trocar 44 inserted into the abdominal cavity is once pulled out, the silicone tape holding the target organ is pulled out from the hole, and then the trocar 44 is reinserted to insert the target organ. Since the lifting method is adopted, the work is complicated and time-consuming, and there is a problem that the movable range such as the pulling direction of the organ is limited.
