Abstract: A radiation generating apparatus includes a target base, a target, an electronic beam generating device, a tube, a tank, and a porous structure. The target is disposed on the target base. The electronic beam generating device is adapted to generate an electronic beam, and the electronic beam is emitted to the target to generate a radiation. The tube accommodates the target and the electronic beam generating device. The tank is connected to the target base and accommodates the tube. The porous structure is roundly disposed between the tank and the tube and contacts an inner wall of the tank and an outer wall of the tube. A cooling fluid flows through the porous structure to dissipate the heat of the porous structure.

Abstract: A radiation generating apparatus includes a target base, a target, a holding assembly and an electronic beam generating device. The target is disposed on the target base. The holding assembly holds the target base. The electronic beam generating device is adapted to generate an electronic beam, wherein the electronic beam is emitted to the target to generate a radiation. The target, the holding assembly and the electronic beam generating device are located at the same side of the target base.

Abstract: A bone screw includes a front portion, a rear portion, and a shaft portion. The shaft portion is fixedly joined to the front portion and the rear portion, so as to form an integral bone screw. The Young's modulus of the shaft portion is smaller than that of the front portion and that of the rear portion.

Abstract: A coil-integrated pad assembly for inductively heating a hyperthermia needle device includes a barrier pad and an electromagnetic unit. The barrier pad is adapted to be inserted into a patient's body and to be placed between the hyperthermia needle device and a non-target tissue of the patient's body when the hyperthermia needle device penetrates a target tissue. The electromagnetic unit has a coil that is at least partially disposed in the barrier pad and that is electrifiable to generate a magnetic field sufficient to inductively heat the hyperthermia needle device.

Abstract: An electromagnetic hyperthermia assembly includes: a substrate; a plurality of hyperthermia needles each having a needle portion that extends through and downwardly from the substrate and that has a needle tip distal from the substrate; and a guiding plate having a plurality of through holes. The needle portions of the hyperthermia needles respectively and removably extend through the through holes such that the guiding plate is movable along the needle portions and between the substrate and the needle tips of the needle portions. The through holes keep the needle tips spaced apart from each other at predetermined positions.

Abstract: A guidable endoscope is described, which includes a rigid guiding part, a bending controllable part, a rigid endoscope body and a handle part. The rigid guiding part has a first end and a second end opposite to each other. The bending controllable part has a first end and a second end opposite to each other. The first end of the bending controllable part is directly connected to the second end of the rigid guiding part. The rigid endoscope body has a first end and a second end opposite to each other. The first end of the rigid endoscope body is directly connected to the second end of the bending controllable part, and the bending controllable part can be bent relative to the rigid guiding part or the rigid endoscope body. The handle part is connected to the second end of the rigid endoscope body.

Abstract: The disclosure provides a thermotherapy needling instrument with tissue injection, including: a casing, an outer needle, an inner needle and a working needle. The casing has an inlet, an outlet and an inner channel. The outer needle is connected to the casing, and is in communication with the inner channel. The inner needle is disposed in the inner channel of the casing and the outer needle, and the inner needle has at least one opening The at least one opening is in communication with the inner channel so that the cooling agent flows in circulation. The working needle is connected to the outer needle so as to receive the injectant for injection and tissue ablation. By using the thermotherapy needling instrument, when sampling or injection is required during thermotherapy, the injection efficacy can be achieved by withdrawing the inner needle only. Therefore, efficacy of tissue injection and ablation thermotherapy can be achieved.

Abstract: A bone fixation guide device is adapted for fixing a bone plate on a bone, wherein the bone plate has at least two screw holes. The bone fixation guide device includes: a handheld holder having a through hole; a first guide sleeve having a guide hole, adapted for passing through the through hole of the handheld holder, and fixed to the bone plate; and a guide plate having a fixing portion and at least two openings, the fixing portion adapted for being assembled on the first guide sleeve, whereby the guide plate is disposed on the handheld holder, wherein the screw holes of the bone plate correspond to the openings of the guide plate.

Abstract: A deep magnetic field generating apparatus includes a first coil unit and a second coil unit. The second coil unit is connected with the first coil unit, and disposed around the first coil unit horizontally. Accordingly, the deep magnetic field generating apparatus can generate a desired deep magnetic field.

Abstract: An electromagnetic thermotherapy needle includes a needle body, a covering element, and a holding portion. The material of the needle body includes a magnetically susceptible material. The needle body is formed integrally as one piece and includes a front portion and a rear portion. The front portion has a tip end, and a radial width of the front portion is larger than that of the rear portion. The covering element covers the rear portion, and includes a magnetically non-susceptible material. The holding portion is connected with the covering element or the needle body.

Abstract: A bone screw includes a front portion, a rear portion, and a shaft portion. The shaft portion is fixedly joined to the front portion and the rear portion, so as to form an integral bone screw. The Young's modulus of the shaft portion is smaller than that of the front portion and that of the rear portion.
