The present invention provides an ablation catheter and an ablation system, comprising: a rod-shaped control member; an outer catheter including a first tube body and a second tube body, the first tube body is fixedly connected to the distal end of the rod-shaped control member , the second tubular body is sleeved outside the rod-shaped control member, and the rod-shaped control member can move relative to the second tubular body along the axial direction of the second tubular body; and a balloon is provided Outside the rod-shaped control element, the proximal end is fixedly connected to the second tube body, and the distal end is fixedly connected to the first tube body. Since the rod-shaped control member moves relative to the second tubular body along the axial direction of the second tubular body, the distance between the distal end of the second tubular body and the distal end of the first tubular body may change, and the balloon will The tube body and the second tube body can be deformed under the traction, so that the shape of the balloon can be adjusted, so the adaptability of the balloon to the shape of different target occlusion objects can be improved, thereby improving the occlusion of the balloon Effect.

The invention relates to a safety device for a vehicle door handle, said device comprising: - an activation element (2) configured to activate a latch, wherein a bump to the safety device causes the activation element (2) to activate the latch; - a blocking element (3), configured to rotate about a blocking axis (30) from a disengaged position to a blocking position due to a collision, wherein the blocking element (3) is used to block the actuating element (2) in the blocked position, wherein the actuating element (2) A receiving portion (4) is included, and the blocking element (3) includes a blocking portion (32) engaged with the receiving portion (4) in a blocking position, wherein during a collision, the blocking portion (32) contacts the first intercepting wall (42) , the second blocking wall (41) and the blocking wall (40) of the receiving part cooperate successively. The invention further relates to a corresponding handle.

The invention relates to the technical field of medical equipment, and provides a freezing device and a tumor ablation device. The device includes a refrigerator; a delivery pipe whose input end is connected to the refrigerator, and whose output end is provided with a spray head; The outside of the spray head, the compression baffle, can be folded and unfolded outside the output end of the delivery tube for adjusting the shape of the expanded frozen pouch; at least two compression baffles are evenly distributed outside the output end of the delivery tube Each of the compression baffles is connected by a flexible film; the compression baffle is connected to the flexible film to form an adjustment plane for adjusting the shape of the freezing pouch after the compression baffle is expanded. The present invention realizes the adjustment of the shape of the frozen pouch by setting the compression baffle, which ensures the full fit between the frozen pouch and the irregular wound surface, and can also operate a single compression baffle according to the needs to perform partial area of ​​the frozen pouch. Adjustment to realize the treatment of wounds from different angles.

The invention provides a preparation method for eucommia and jasmine flower tea and a product thereof. The preparation method comprises the steps of stacking jasmine flower buds at room temperature of 30-33 DEG C and relative humidity of about 80 percent at the air flow speed of 5-6ml / min for nourishing, and then performing flower sifting until the bloom rate of jasmine flowers is over 90 percent and the bloom degree of the jasmine flowers is 88-92 degrees; adding a eucommia tea blank which is subjected to water removing, rolling and drying into water until the moisture content is 10-30 percent, mixing the eucommia tea blank and the jasmine flowers, uniformly stirring, and stewing a mixture at the stack temperature of 38-42 DEG C for 12-14 hours; after stewing and scenting are finished, quickly separating eucommia tea from the jasmine flowers in the scented eucommia and jasmine flower tea mixture to obtain coarse eucommia and jasmine flower tea, baking the coarse eucommia and jasmine flower tea at 80-120 DEG C until the moisture content is 5-8.5 percent, and cooling and packaging to obtain the eucommia and jasmine flower tea product. The product disclosed by the invention has the effects of adjusting blood fat, reducing pressure, improving eyesight, relaxing the bowels, resisting aging, diminishing inflammation, enhancing the immunity function and the like; the special scenting method can effectively guarantee the natural taste and pure fragrance of the eucommia tea and the jasmine flowers.

The invention belongs to the technical field of wide-angle scanning phased array antennas, and discloses a wide-angle scanning phased array antenna using a special pattern array element and a design method thereof. The low-profile phased array adopts a sub-array with a special pattern as an array element, so that the low-profile phased array antenna has a stable gain in a wide range of scanning angles or meets higher gain requirements at large scanning angles; The above-mentioned special pattern has a symmetrical distribution of the maximum gain direction between the normal direction of the array plane and the direction of the maximum scanning angle and close to the direction of the maximum scanning angle, forming the characteristic of the central depression of the pattern; the depth of the central depression of the array element pattern is determined according to the It is required to design, the stronger the directionality of the array factor, the deeper the central depression. On the premise of not changing the array factor of the phased array, the present invention can realize the stable gain of the low-profile phased array antenna in a wide scanning angle range, or meet the requirement of higher gain at a large scanning angle.
