[0047] The marking system 1 of the present embodiment is a system for marking a desired position of a luminal organ that can be visually recognized from the abdominal cavity side which is the outer side of the luminal organ. For example, figure 1 As shown, it includes: a marker 10 indwelling through the wall of the luminal organ, a feeder 20 piercing into the wall of the luminal organ, and an indicating device indicating the desired position from the inside of the luminal organ 30.

[0048] exist figure 2 The marker 10 in this embodiment is enlarged in the middle. The marker 10 is formed in a coil shape using, for example, nickel-titanium alloy, resin, or the like, and after being stretched into a shape other than the coil shape by applying an external force, it can return to the coil shape by removing the external force.

[0049] image 3 and Figure 4 It is an enlarged cross-sectional view showing the tip portion of the feeder 20 . The feeder 20 includes: a cylinder por...

Abstract

Provided is a marking system, comprising: a marker which is positioned to transect a wall part of a luminal organ; an applicator which further comprises an insertion part which is capable of insertion into the wall part, and wherein at least a portion of the marker is housed; and a pointer device, further comprising an introduction part which is formed long and flexible and wherethrough the insertion part is capable of penetrating, and a light source part which is positioned within the introduction part. At least a portion of the introduction part is light occlusive on the outer circumference surface, suppressing leakage of light emitted from the light source part to the outside of the introduction part.

Description

technical field [0001] The present invention relates to a marking system and, more particularly, to a marking system for marking through the wall of luminal tissue inside and outside a desired location of the luminal tissue. [0002] This application claims priority based on Japanese Patent Application No. 2014-123431 for which it applied in Japan on June 16, 2014, and uses the content here. Background technique [0003] Conventionally, in the treatment of early malignant tumors, for example, EMR (endoscopic mucosal resection), ESD (endoscopic submucosa dissection), etc., endoscopic resection of the digestive tract, etc. A technique for lesions arising on the mucous membranes within the luminal viscera. When the lesion infiltrates deeper than the submucosa, radical treatment is usually performed with extensive surgical excision. Sometimes even benign submucosal tumors and the like undergo extensive surgical resection. However, the trauma of surgical resection is large, an...
