Problems solved by technology

[0005] However, since the tip diameter of the transparent cap is larger than that of the endoscope, it is difficult to sneak into a thin incision to open the wound
In addition, even if it is submerged inside, the mucous membrane may slip from the cap due to the endoscopic operation for incision / peeling, and in this case, it is necessary to perform the operation of submerging the cap again

Embodiment Construction

[0081] Embodiments will be described below.

[0082] figure 1 A schematic diagram of the medical device cap 10 according to the first embodiment is shown.

[0083] The medical device cap 10 of the first embodiment has: a base member 11 attached to the front end 2a of the insertion portion 2 of the medical device 1; a shaft member 12 attached to the base member 11; and a link member 13 capable of The shaft member 12 is swingably supported, the connection member 14 is attached to the link member 13 , and the blade 15 is rotatably supported by the connection member 14 . The shaft member 12, the link member 13, the connecting member 14, and the blade 15 constitute a protrusion. In addition, the shaft member 12, the link member 13, and the connection member 14 constitute a side portion, and the blade 15 constitutes a front portion. Furthermore, the link member 13 and the connection member 14 constitute an arm portion.

[0084] The base member 11 is detachably attached to the ou...

Abstract

A cap (10) for a medical device includes a base member (11). The base member (11) is attached to a distal portion (2a) of an insertion part (2) of a medical device (1) having an endoscope (4). On the base member (11), two linking members (13) are swingably supported by shaft members (12). On distal ends of the linking members (13), a blade (15) is rotatably supported by coupling members (14). The blade (15) has a treatment hole (15a). A treatment part (3) that is inserted through the medical device (1) has a treatment distal portion (33). The treatment distal portion (33) is inserted through the treatment hole (15a). In an endoscopic submucosal dissection, the treatment distal portion (33) makes an incision between a submucosa (101) and mucous membrane (102). The blade (15) pushes up the mucous membrane (102) that is dissected from the submucosa (101), thereby enabling the treatment part (3) to be slipped under the mucous membrane (102).

Description

technical field [0001] The present invention relates to a medical device cap that can be used as a medical device that is inserted into a patient's body cavity during surgery or the like to perform observation, treatment, and the like. Background technique [0002] Medical equipment for observing and treating internal organs of a body cavity is widely used by inserting a long and thin insertion part into a patient's body cavity and pulling the tip of the insertion part with a wire or the like. Since the front end of the medical device observes and treats the internal organs of the body cavity, there is a high possibility of dirt adhering thereto. Therefore, a technique of installing a cap on the front end of the medical device is used. [0003] As a general treatment method for gastrointestinal lesions, there is endoscopic mucosal resection (EMR: Endoscopic Mucosal Resection) in which lesions are excised using an endoscope. In particular, endoscopic submucosal dissection (...
