Definitions
- an endoscope includes a cystoscope, a mediastinoscope, or the like that is inserted into the body and operated.
- Endoscopic surgery is a process of making a small hole in the patient's body, inserting an endoscope, special scalpel, scissors, forceps, etc. into the hole, and observing the state of the organ etc. with the endoscope outside the body. This is a method of performing surgery.
- the suture needle When a tissue such as an organ is sutured, the suture needle is held with special forceps as described in the following patent document, and the forceps are operated externally.
- Patent Document 1 Japanese Patent Laid-Open No. 2002-224128
- Patent Document 3 Japanese Patent Laid-Open No. 2002-11017
- the suturing operation in endoscopic surgery is difficult to remove the tissue force needle. More specifically, in the suturing operation, the needle 102 is pierced into the tissue at the suture site 103 as shown in FIG. 13, and the tip of the needle is exposed to the surface side of the tissue using the arc shape of the needle 102. Further, as shown in FIGS. 14, 15, and 16, the tip of the needle 102 exposed with the other forceps 101 is grasped, and the forceps 101 is operated to remove the entire needle 102 from the tissue force.
- the tip of the needle 102 exposed on the surface side of the tissue may be very slight, and the forceps 101 is difficult to bite. That is, in order to extract the needle 102 toward the distal end side, it is necessary to force only the distal end portion of the needle 102, but if the exposed portion of the distal end of the needle 102 is very small, it will entangle part of the tissue. . On the other hand, when trying to pinch only the needle 102 and searching the periphery of the needle 102 with the forceps 101, the forceps hit the tip of the needle 102 and the surrounding tissue, and the needle tip is buried in the tissue.
- An invention for solving the above-described problems is a suturing support device including a needle insertion body through which a suturing needle can be inserted.
- the suture assisting device of the present invention assists the above-described work of removing the needle. That is, in the suturing operation in the endoscopic operation, as described above, it is necessary to pierce the tissue and extract the needle exposed on the surface side.
- the suture assisting device of the present invention supports this work, and inserts a needle that penetrates the tissue and is exposed on the surface side into the needle insertion body. More specifically, the surgeon operates a rod-like member protruding outside the patient's body, and presses the needle insert against the tip of the needle where the surface force of the tissue is also exposed. As a result, the needle pierces the needle insert. Subsequently, the other end side of the rod-shaped member protruding outside the patient's body is operated to rotate or move the needle insertion body. As a result, the needle moves while being held by the needle insert, and the tissue force is released.
