Abstract

The present invention relates to the ligation performance that accompanies the structure of a surgical ligation clip for temporarily or permanently ligating tissue, such as blood vessels, during a surgical operation, thereby preventing bodily fluids such as blood from leaking, wherein the ligation clip uses the intentional deforming property of a polymer material. The ligation clip is a polymer ligation clip in which a female leg protrudes upward, and a male leg protrudes upward to correspond to the female leg, wherein the respective rear ends of the female and male legs are connected by a hinge. A blood vessel placed between the female leg and the male leg is ligated as a female head and a male head provided on the tips of the legs, respectively, are fastened by elasticity and recovery. The hinge is composed of an inner hinge part and an outer hinge part with a slit therebetween. A protrusion part on the outer hinge part serves as a pressing means for deformation folding when the inner hinge part collinear with an inner blood vessel contact surface of the ligation clip deforms in the slit space during ligation.

Each of the downstream duration and the upstream duration is configured to sequentially include a second receive slot, a second receive processing slot, a first receive slot, a first receive processing slot, a transmit slot, a transmit processing slot, a first acknowledge slot, a first acknowledge processing slot, a second acknowledge slot, and a second acknowledge processing slot, and wherein bidirectional communication can be performed between the sink node and the terminal node in a single period of the active duration. In the wireless sensor network, a transmit processing duration TXP is maintained in a receiving mode capable of receiving data from other nodes, so that a new node can be easily joined as a terminal node or an intermediate node. In addition, in the wireless sensor network, each of the upstream duration and the downstream duration is provided with consecutive two receiving durations, so that, although links to consecutive two nodes are disconnected, it is possible to simply recover the links.

Abstract

A communication method for a mobile sensor node in a wireless sensor network includes: in a state that the mobile sensor node performs synchronization by a message reception interrupt from a parent sensor node and determines an uplink active duration and a downlink active duration, transmitting a message to the parent sensor node in the transmitting duration of the uplink active duration, receiving and processing messages from the parent sensor node and sensor nodes linearly connected around the parent sensor node in the receiving duration of the uplink active duration, and resetting a new parent sensor node using the received signal strength indications RSSIs of the received messages; and transmitting a message to the parent sensor node in the transmitting duration of the downlink active duration, checking whether or not a message is received from the parent sensor node in the receiving duration of the downlink active duration, if the message is not received from the parent sensor node, determining that time synchronization fails and resetting a new parent sensor node, and if the message is received from the parent sensor node, performing time synchronization according to a message reception interrupt from the parent sensor node.
