Detailed description of the invention
With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.
Embodiment 1
According to shown in Fig. 1 to Fig. 6, the present embodiment is a kind of marmem blade plate external member, includes memory alloy plate osteosynthesis, cooling main frame 7, and connects the joint 8 of cooling main frame and memory alloy plate osteosynthesis;
Described memory alloy plate osteosynthesis includes mainboard body 1 and one-body molded many groups anchor ear arm 2 in mainboard body both sides, two arm ends often organizing anchor ear arm form the latch that engaging arm 21, two sidewalls that engaging arm is relative mutually staggered position form engaging location mutually respectively; Be provided with cooling pipe 5 in described mainboard body and each group anchor ear arm, the external wall of described mainboard is provided with the inlet opening 3 and liquid outlet 4 that are connected with cooling pipe two ends respectively.Described memory alloy plate osteosynthesis often organizes anchor ear arm two support arms after installing are engaging in together by the latch cooperation in engaging arm, form a closed ring-type, constant intensity is high, is more conducive to hinder symphysis, and compensate for the intensity that this blade plate hollow-core construction causes and reduce.
Described inlet opening and liquid outlet are positioned at one end end position of mainboard body; Described cooling pipe comprises the main pipeline 51 along mainboard body edge placement, and along the Outer Tube 52 of anchor ear arm edge placement, and along the interior conduit 53 of Outer Tube disposed inboard, described Outer Tube extends to engaging arm terminal position; Described interior conduit in each anchor ear arm is communicated with main pipeline respectively with Outer Tube; The cross-sectional area of described main pipeline be Outer Tube, 1.3 times of interior conduit cross-sectional area sum; The cross-sectional area of described Outer Tube is 2/3 of interior conduit cross-sectional area.
Described mainboard body and anchor ear arm inside are positioned at the scope that main pipeline and each interior conduit surround, and the interior conduit of each anchor ear arm, scope between Outer Tube are provided with the copper material bed of material 6, and mainboard body and anchor ear arm skin are shape memory alloy material layer.
Described mainboard body is elongated rectangular shape shape, mainboard body intermediary form has the rectangular aperture of a strip, mainboard body is connected with between two of rectangular aperture long limits the tensioned lines 9 of more than three, described tensioned lines one end is fixedly connected with a long limit, the other end is fixedly connected with an adjustment screw 91, and adjustment screw and mainboard body are connected by thread interference;
Shown in composition graphs 7, described cooling main frame includes housing 71, and being provided with a metal partion (metp) in housing will be divided into a water storage cavity and an electric chamber in housing; Above described housing, corresponding water storage cavity is provided with water filling port, water filling port is sealedly connected with lid 72, and below described housing, the position of corresponding water storage cavity is provided with the connection-peg 75 be connected with joint, connection-peg has two fluid passages; Be provided with liquid pump 76 in described water storage cavity, liquid delivery side of pump is connected with a fluid passage; Described electric intracavity is provided with refrigerating sheet 77, circuit board 78 and accumulator 79, and the huyashi-chuuka (cold chinese-style noodles) of described refrigerating sheet is connected on metal partion (metp); The lateral wall of the corresponding water storage cavity of described housing is provided with the press button 74 controlling liquid pump work, and the sidewall in the corresponding electrically chamber of described housing is provided with the toggle switch controlling refrigerating sheet; Described press button, toggle switch, refrigerating sheet and accumulator are connected with circuit board respectively; The two side of described housing forms at least one group of raised line 73 being beneficial to and grasping.
Described joint 8 includes and coordinates with connection-peg the grafting of grafting to overlap 81, and is connected to the feed liquor intubate 82 of grafting cover below and returns liquid intubate 83, feed liquor intubate, return liquid intubate respectively with inlet opening, liquid outlet grafting; The end sleeve of feed liquor intubate and time liquid intubate is provided with silica gel sheath, is beneficial to and is tightly connected with inlet opening, liquid outlet.Described feed liquor intubate and time liquid cannula end are also connected with sealing-plug, extract again, avoid the liquid cooled in main frame to flow out when needs cooling blade plate.Described joint 8 can according to the specification of inlet opening, liquid outlet on blade plate, distance correspondingly select, make cooling main frame can with the blade plate adapted of different size.
Before removing memory alloy plate osteosynthesis, the joint of corresponding specification is set on the connection-peg of cooling main frame, saline injection in the water storage cavity of cooling main frame, refrigerating sheet work is started by toggle switch, normal saline temperature is made to drop to less than 5 DEG C, then feed liquor intubate and the sealing-plug returned in liquid intubate on joint is pulled out, by feed liquor intubate and time liquid intubate and inlet opening, liquid outlet docks, then switch activated liquid pump is pressed the button, normal saline through cooling circulates along cooling pipe and cools blade plate, cooling main frame is removed after blade plate temperature reaches requirement, pull down blade plate.
Embodiment 2
Shown in composition graphs 7, the present embodiment, on the basis of embodiment 1, adds following feature: the support arm often organizing anchor ear arm forms a side protuberance 22 with engaging arm homonymy side near the position of mainboard body, and the end of side protuberance is bending to mainboard body direction.
After often organizing the engaging arm engaging on anchor ear arm, be in the muscle depths of synthetism position, be unfavorable for being unclamped by anchor ear arm when removing blade plate, described side protuberance to be convenient to a support arm, toward breaking into two with one's hands away from latch side, be beneficial to and take anchor ear arm convenient and strength-savingly apart.
Embodiment 3
The difference of the present embodiment and embodiment 1 or 2 is: described mainboard body forms the through hole passed for tensioned lines one end, and the external wall of mainboard then forms perpendicular to the position of through hole the screw hole connecting adjustment screw.After blade plate is cooled, be in shaping state, now adjust the width of mainboard body to suitable, further tensioned lines, and adjustment screw locked subsequently thus tensioned lines compressed, such constant intensity is higher than embodiment 1 or 2.
