A medical device is disclosed capable of reducing risk factors of an anastomotic leakage after a surgical operation is performed. The medical device includes an adhesion promotion sheet configured to include an adhesion promotion portion promoting adhesion of biological tissues and a frame portion provided outside the adhesion promotion portion in a plane direction and a pulling unit connected to the adhesion promotion sheet and configured to deform a second region so as to cover at least a portion of an outer peripheral surface of a biological organ to be joined with a pulling operation.

Medical device

To reduce the risk of a ruptured suture after a surgery or the like, a medical apparatus includes a biodegradable sheet in which a plurality of through-holes are formed, a value of a ratio (D/P) of a hole diameter D to a pitch P of the through-hole is in a range of 0.25 or more and less than 40. Such a medical apparatus is useful as an adhesion promoting device for promoting adhesion of biological tissue.

Medical apparatus and adhesion promoting device using same

Provided is a treatment method that reduces risk factors contributing to anastomotic leakage by using a medical device. The treatment method includes placing a medical device including a sheet-like main body portion for promoting adhesion between biological tissues between one joint target site and another joint target site of a biological organ to be joined, and joining the one joint target site and the other joint target site to each other in a state where at least a portion of the main body portion is interposed between the one joint target site and the other joint target site.

Treatment method for joining biological organs

A sprayer includes: a sprayer body; a nozzle extending from the sprayer body; and an irradiation unit disposed on a leading end of the nozzle and emitting light that is oriented and diffuses in a leading end direction of the nozzle. The nozzle includes: an elongated nozzle body extending from the sprayer body and having a curved portion on a leading end side; and a nozzle head disposed on a leading end of the nozzle body. The irradiation unit is arranged inside a curve shape of the curved portion.
