Specific embodiment

A specific embodiment of the invention is made a detailed explanation below according to attached drawing.

Embodiment 1

According to fig. 1 to fig. 6, the present embodiment is a kind of marmem bone plate external member, includes memorial alloy Bone plate, cooling host 7, and connect the connector 8 of cooling host and memory alloy plate osteosynthesis;

The memory alloy plate osteosynthesis includes the multiple groups anchor ear arm 2 of mainboard body 1 and integrated molding in mainboard body two sides, Two arm ends of every group of anchor ear arm are separately formed the engaging arm 21 that position mutually staggers, the opposite side wall of two engaging arm Form the latch for being mutually clamped positioning;Cooling pipe 5, the external wall of mainboard are equipped in the mainboard body and each group anchor ear arm It is equipped with the inlet opening 3 and fluid hole 4 being connected respectively with cooling pipe both ends.Every group after the memory alloy plate osteosynthesis installation Two support arms of anchor ear arm are locking together by the latch cooperation in engaging arm, form a closed ring-type, fixing intensity Height is more conducive to hurt symphysis, and compensates for strength reduction caused by the bone plate hollow structure.

The inlet opening and fluid hole is located at one end end position of mainboard body;The cooling pipe includes along mainboard The main pipeline 51 of body edge arrangement, along the Outer Tube 52 that anchor ear arm edge is arranged, and along in Outer Tube disposed inboard Pipeline 53, the Outer Tube extend to engaging arm terminal position;Said inner tube road in each anchor ear arm and Outer Tube respectively with Main pipeline connection;The cross-sectional area of the main pipeline is Outer Tube, 1.3 times of interior conduit cross-sectional area sum;The Outer Tube Cross-sectional area be interior conduit cross-sectional area 2/3.

The mainboard body and anchor ear arm are internally located at main pipeline and each interior conduit surround in the range of and each armful It binds round the range between the interior conduit of arm, Outer Tube and is equipped with the copper material bed of material 6, mainboard body and anchor ear arm outer layer are marmem material The bed of material.

The mainboard body is in strip rectangle shape, and mainboard body intermediary form has the rectangular aperture of a strip, mainboard body There are three above tensioned lines 9 for the upper connection between two long sides of rectangular aperture, and described tensioned lines one end is fixed with a long side Connection, the other end are fixedly connected with an adjusting screw 91, are adjusted screw and mainboard body and are cooperatively connected by thread interference;

As shown in connection with fig. 7, the cooling host includes shell 71, and a metal partion (metp) is equipped in shell by shell points It is divided into a water storage cavity and an electrical chamber;Corresponding water storage cavity is equipped with water filling port, the company of sealing on water filling port above the shell It is connected to lid 72, the position of corresponding water storage cavity is equipped with the connection-peg 75 connecting with connector below the shell, has on connection-peg Two fluid passages;Liquid pump 76 is installed, the outlet of liquid pump is connected with a fluid channel in the water storage cavity;The electrical chamber Refrigerating sheet 77, circuit board 78 and battery 79 are inside installed, the huyashi-chuuka (cold chinese-style noodles) of the refrigerating sheet is connected on metal partion (metp);The shell The lateral wall of corresponding water storage cavity is equipped with the button switch 74 of control liquid pump work, and the shell corresponds to the side wall installation of electrical chamber There is the toggle switch of control refrigerating sheet;The button switch, toggle switch, refrigerating sheet and battery are connect with circuit board respectively; At least one set of raised line 73 conducive to grasping is formed on the two sidewalls of the shell.

The connector 8 include with connection-peg cooperation grafting grafting set 81, and be connected to grafting set lower section into Liquid intubation 82 and return liquid intubation 83, feed liquor intubation, return liquid intubation respectively with inlet opening, fluid hole grafting;Feed liquor intubation and time liquid The end sleeve of intubation is equipped with silica gel sheath, is conducive to be tightly connected with inlet opening, fluid hole.The feed liquor intubation and time liquid cannula end It is also connected with sealing-plug, is extracted again when needing cooling bone plate, the liquid outflow in cooling host is avoided.The connector 8 It can correspondingly be selected according to inlet opening, the specification of fluid hole, distance on bone plate, allow and cool down host and different rule The bone plate adapted of lattice.

Before removing memory alloy plate osteosynthesis, the connector of corresponding specification is set on the connection-peg of cooling host, in cooling Saline injection in the water storage cavity of host starts refrigerating sheet work by toggle switch, physiological saline temperature is made to drop to 5 DEG C Hereinafter, then pull out the intubation of feed liquor on connector and return the sealing-plug in liquid intubation, feed liquor is intubated and is returned liquid intubation and inlet opening, Then fluid hole docking presses button switch starting liquid pump, circulates docking along cooling pipe through cooling physiological saline Bone plate is cooled down, and is moved back until synthetism plate temperature reaches requirement except cooling host, is removed bone plate.

Embodiment 2

As shown in connection with fig. 7, the present embodiment on the basis of embodiment 1, increases following feature: one of every group of anchor ear arm Side protrusion 22 is formed close to the position of mainboard body with the ipsilateral side of engaging arm on support arm, and the end of side protrusion is to mainboard body Direction bending.

Due to being in the muscle depths of synthetism position after the engaging arm engaging on every group of anchor ear arm, it is unfavorable for removing bone plate When anchor ear arm is unclamped, the side protrusion is convenient for a support arm toward breaking into two with one's hands far from latch side, conducive to dismantling convenient and strength-savingly Anchor ear arm.

Embodiment 3

The present embodiment and the difference of embodiment 1 or 2 are: forming on the mainboard body and to pass through for tensioned lines one end Through-hole, the external wall of mainboard then form the screw hole that connection adjusts screw perpendicular to the position of through-hole.After bone plate is cooled In plastic shape state, the width of mainboard body is adjusted at this time to suitable, and further tensioned lines, will then adjust screw locking to will Tensioned lines compress, and such fixing intensity is higher than embodiment 1 or 2.
