A device / system and a method for the treatment of enlarged prostate and other urologic abnormalities are presented. This system enables the simultaneous attachment of several interstitial coaguiative treatment probes as well as an ablative fiber to perform a combined treatment utilizing the intervention time and the time of the localized anesthesia effect in an optimal manner. The amount of tissue removed by the urologist by vaporization can be kept to a minimum, thanks to the (delayed) improvement of the achieved symptom scores resulting from the denaturalizing effect of the interstitial coaguiative fibers. In one preferred embodiment, two or more types of delivery systems are embedded in a single device for achieving optimal tissue ablation and coagulation effects including at least one non-laser source such as microwave energy, capable of producing radiation energy to coagulate tissue and at least one laser source capable of producing radiation to ablate tissue. In another preferred embodiment, device comprises two or more laser sources which emit at adjustable wavelengths controllable by physician according to ablative and coaguiative needs and tissue penetration needs depending on their effective absorption in different tissue components. Wavelengths ranges are chosen such that tissue absorption properties change sensibly with small variations of such wavelengths, based on a steep region of the absorption curve. Radiation may be applied in continuous, semi-continuous or pulsed wave, in different combinations. In another preferred embodiment, optical fiber has a central core for transmitting laser radiation, and a cladding layer about the core that may further transmit other laser radiation of a different or a same wavelength as the core.

The invention discloses a bird nest eliminating device used on a high-voltage tower. The bird nest eliminating device comprises a vertical rod and a grabbing mechanism. The grabbing mechanism comprises a box body, a fixed clamping handle, a movable clamping handle, a telescopic spring and a control mechanism. The movable clamping handle and the fixed clamping handle are respectively arranged at the left end and the right end of the box body. The inside of the fixed clamping handle and the inside of the movable clamping handle are respectively provided with a plurality of cleaning needles. The box body comprises a top board, a left side board, a right side board and a bottom board. The bottom of the bottom board is connected with the upper end of the vertical rod. The fixed clamping handle is connected with the top board. The lower end of the movable clamping handle penetrates through a box body chute and extends into the box body. The telescopic spring is mounted in the box body. The control mechanism comprises a traction rope, a reel, a rocking handle, a hook, a guiding wheel and a pulley. The bird nest eliminating device has advantages of simple structure and convenient operation. Not only can integral stable grabbing and movement of the bird nest for preventing scattering or inclination of the bird nest in the grabbing process be realized, but also the bird nest eliminating device is suitable for integral movement of the bird nests with different sizes. The bird nest eliminating device performs functions of effectively eliminating the bird nests on the high-voltage tower and ensuring normal operation of a power grid.

The present invention discloses a pruning tool (100) which includes a cutting assembly (102) with a blade arrangement including at least one movable component (104), a drive cable (156) attached to the at least one movable component at a first end (158) of the drive cable which is configured to actuate the at least one movable component, and an intermediate portion (103) coupled to the cutting assembly. Further, the pruning tool includes a handle (126) provided adjacent to the intermediate portion, wherein the handle is configured to be grasped by a user during operation of the pruning tool. The handle has a length in a range of about 0 cm to 30cm. A channel (136) is formed in the handle, wherein a second end (160) of the drive cable is received through the channel.

The invention discloses a pretreatment method for an anchor cable group penetrating through a shield driving fracture surface. The pretreatment method comprises the steps of adopting a warehouse-jumping method to construct an artificial wellhole of a preorder; arranging a working platform at a position where the anchor cable can be found, cutting off the anchor cable, and arranging a removing tool on the working platform; adopting the removing tool to loosen and drag out the anchor cable; backfilling the artificial wellhole and recovering the ground; adjusting the orientation and the diameter of the artificial wellhole of a postorder according to the residual anchor cable condition of the artificial wellhole of the preorder, but guaranteeing that a plum blossom connection is formed between the artificial wellhole of the preorder and the artificial wellhole of the postorder; repeating the steps above until all the anchor cables are removed. The pretreatment method adopts the warehouse-jumping method to dig the artificial wellhole and has a flexible hole arrangement, therefore, not only is construction area reduced, but also construction speed is improved; plum blossom connections are adopted between a number of artificial wellholes, continuous construction regions are formed on a shield path so as to ensure that all the anchor cables can be removed. The pretreatment method for the anchor cable group which passes through the shield driving fracture surface belongs to the field of anchor cable removing.
