摘要： A suturing device includes: a needle; and a shuttle. The needle has an elongated shape extending in a predetermined direction and is configured to hold a first thread-like member. The needle is reciprocally movable forward and backward in the predetermined direction and is rotatable about an axis extending in the predetermined direction. Rotation of the needle about the axis permitting the first thread-like member to cross the needle to form a loop in the first thread-like member. The shuttle includes a holding portion. The holding portion is configured to hold a second thread-like member. The shuttle is configured to permit the holding portion to pass through the loop.

摘要： A suturing device includes a plurality of suture needles, a first-thread holding mechanism, a needle moving mechanism, and a thread turning structure. The thread turning structure is configured to locally turn a portion of a first thread hooked on a distal end portion of each of a plurality of suture needles in the first thread stretched in a first direction around a needle axis thereof such that the portion of the first thread extends in a direction along a third direction intersecting the first direction and a second direction, in a state where the plurality of suture needles have been moved in the second direction. Each of the plurality of suture needles has a side surface formed with a threading recessed groove extending through the side surface in the first direction in a state where each of the plurality of suture needles has been moved in the second direction.

摘要： An air purifier includes a housing having an air inlet, an air outlet, and a cavity portion connecting the air inlet and the air outlet, two blowers disposed in the cavity portion and each including a fan rotatable to generate a flow of air, and a filter disposed in the cavity portion. During rotation of the fan, the two blowers each suck in air from outside of the housing through the air inlet into the cavity portion, and blow the air having passed through the filter from the air outlet to the outside of the housing. A direction in which the air inlet is open crosses a direction in which the air outlet is open. An opening area of the air outlet is smaller than an opening area of the air inlet.

摘要： A suturing device includes first and second holding members, a plurality of needles, a needle moving mechanism, and a suture hook. The first and second holding members are configured to move toward and away from each other to sandwich therebetween edges of a cut. The needles are disposed at the first holding member and aligned in a needle arrangement direction with their points pointing to the second holding member. The needles are configured to hold a suture at tips thereof. The needle moving mechanism is configured to move the plurality of needles toward the second holding member. The suture hook is disposed at the second holding member and configured to move along the needle arrangement direction to catch the suture that has reached the second holding member via the edges of the cut by movement of the needles toward the second holding member by the needle moving mechanism.

摘要： In a suturing device, a casing has an elongated shape extending in a longitudinal direction. A needle is positioned in the casing, is configured to hold a first thread-like member, and has a tip end reciprocally moving along a path extending between a first position and a second position positioned backward than the first position in the longitudinal direction. A depression is formed in a peripheral wall of the casing, is positioned between the first and second positions in the longitudinal direction, and is configured to expose the needle to an outside of the casing. The shuttle includes a holding portion configured to hold a second thread-like member. The shuttle is configured to move within the casing at a third position between the first position and the depression in the longitudinal direction to change relative position between the second thread-like member and a loop formed in the first thread-like member.

摘要： A knot tying device includes a holding portion, a first loop forming portion, a positioning portion, and a first suture hook. The holding portion including a suture hooking portion at its distal end portion. The holding portion is configured to hold a suture that is engaged with the suture hooking portion. The first loop forming portion is configured to form a loop of the suture fixedly. The positioning portion is configured to position the suture hooking portion with which the suture is engaged, at a specific position. The first suture hook is configured to pass through the loop, and catch and hold the suture in a state where the suture hooking portion with which the suture is engaged is located at the specific position. The first suture hook causes the suture to pass through the loop, thereby tying a knot in the suture.

摘要： An air purifier includes a housing, a first blower, a second blower, and a filter. The housing has a cavity inside, an inlet and an outlet. The first blower has a first fan in the housing. The second blower has a second fan in the housing. The second blower faces the first blower in an opposing direction. The inlet is located between the first blower and the second blower in the opposing direction. The inlet opens in a direction intersecting the opposing direction. The first fan of the first blower and the second fan of the second blower generate airflow such that air flows into the cavity through the inlet, and flows from the cavity through the filter to the outlet.
