For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of Wicresoft rib ail gun, comprise rifle body, gun barrel and handle, described gun barrel is arranged at the front end of described rifle body, described handle is arranged at the rear end, bottom of described rifle body, in described rifle body, be provided with nail kit, the reed of this nail kit is connected with the trigger of described handle, the pushing device of described nail kit take metal spring as power is arranged at described rifle external body and is positioned at same level with gun barrel, the first nail clip of described nail kit and rifle body are inner fixing, the second nail clip of described nail kit is along this first nail clip relative sliding, the gap producing when this first nail clip and the second nail clip relative sliding formed nail passage along rifle body longitudinal extension.
Preferably, above-mentioned Wicresoft rib ail gun, the inner side width of described the first nail clip and the outside width of the second nail clip are 0.8-1.0cm.
Preferably, above-mentioned Wicresoft rib ail gun, the inner side width of described the first nail clip and the outside width of the second nail clip are 0.8cm.
Preferably, above-mentioned Wicresoft rib ail gun, in described rifle body and rifle body, nail kit is rectangular configuration.
A kind of nail of the rib for above-mentioned Wicresoft rib ail gun, is U character form structure, is provided with corner cut at the non-blind end of described rib nail, and the material of described rib nail is Nitinol.
Preferably, above-mentioned rib nail, the amount of contraction of described rib nail is 8%.
Preferably, above-mentioned rib nail, the width of described rib nail is 0.8cm.
This utility model structure has following beneficial effect:
The applied rib nail of above-mentioned Wicresoft rib ail gun, simple in structure, utilize the pyrocondensation cold expanding of Nitinol and the physical features of shape memory and ingehious design is U font special construction, fix at fracture line two ends, compare the therapeutic modality of traditional fracture of rib, this convenient and flexible operation wound is little, little to patient's degree of injury, fracture of rib therapeutic scheme is generally expectant treatment (pectoral girdle is fixing) outward or opens in breast reset wire internal fixation or memorial alloy encircling bone bonding plate fixing at present, this operates particularly for multiple rib fracture, the patients such as flail chest wait critical patient treatment that great convenience is provided, can under local anaesthesia, cut skin and subcutaneous tissue 2-3cm exposure fracture two broken ends of fractured bone along rib direction out of shape, with little towel clamp towel forceps auxiliary reset, then use this ail gun alignment ribs bone stump both sides, ail gun is pressed to fracture cocking, centered by fracture line, rib nail is penetrated and squeezed in the broken ends of fractured bone two frame timber sclerotin, general vertical fracture line is squeezed into two pieces of nails.And can not break parietal pleura, can not cause pneumothorax, because the average thickness of rib is 0.87 ± 0.3cm, the nail length of our design is 0.8cm, vertical with the fracture line like this memory nail of squeezing into has exceeded 1/2 of rib thickness, can play fixation completely, and do not affect intercostal nerves, blood vessel compared with fixing fracture of rib in memorial alloy encircling bone bonding plate.Apply this rib nail and the shooting mode of the similar pistol of custom-designed ail gun, utilize the strength of abrupt release after spring-compressed that rib nail is squeezed into the rib two ends of fracture, easy and simple to handle, time saving and energy saving, general place's fracture fixation is about approximately 10 minutes, and technique has very important clinical practice meaning.
Accompanying drawing explanation
Fig. 1 is the structural representation of Wicresoft described in the utility model rib ail gun;
Fig. 2 is the structural representation of rib nail described in the utility model.
In figure: 1-rifle body 2-gun barrel 3-handle 4-nail kit 5-pushing device 6-rib nail main body 7-corner cut
The specific embodiment
For further illustrating this utility model, now coordinate accompanying drawing to be described in detail:
As shown in Figure 1, described Wicresoft rib ail gun, comprise rifle body 1, gun barrel 2 and handle 3, described gun barrel 2 is arranged at the front end of described rifle body 1, described handle 3 is arranged at the rear end, bottom of described rifle body 1, in described rifle body 1, be provided with nail kit 4, the interior nail kit 4 of described rifle body 1 and rifle body 1 is rectangular configuration, the reed of this nail kit 4 is connected with the trigger of described handle 3, the pushing device 5 of described nail kit 4 take metal spring as power is arranged at described rifle body 1 outside and is positioned at same level with gun barrel 2, the first nail clip of described nail kit 4 and rifle body 1 are inner fixing, the second nail clip of described nail kit 4 is along this first nail clip relative sliding, the gap producing when this first nail clip and the second nail clip relative sliding formed nail passage along rifle body 1 longitudinal extension, the inner side width of this first nail clip and the outside width of the second nail clip are 0.8cm, as shown in Figure 2, the mistake of described Wicresoft rib ail gun is followed closely the rib nail of assembling in passage, this rib nail main body 6 is U character form structure, be provided with sharp-pointed sharp corner cut 7 at the non-blind end of described rib nail, the width of described rib nail is 0.8cm, the material of described rib nail is Nitinol, and the amount of contraction of this rib nail is 8%.
The mode of operation of above-mentioned Wicresoft rib ail gun is similar to the shooting mode of pistol, utilize the strength of abrupt release after the spring-compressed in ail gun that rib nail is squeezed in the rib of fracture, because rib nail has memory effect, can there is martensite to austenitic transformation in the interior tissue of injecting temperature rise rib nail after human body in it, rib nail can be remembered the state before plastotype, therefore when rib nail generation type becomes, produce the strength of drawing close to centre, the power that the rib of fracture is produced to persistent pressure, can effectively promote rib symphysis.
Concrete application is upper, and the using method of above-mentioned Wicresoft rib ail gun is as follows:
(1) after preoperative being ready to complete, above-mentioned rib nail being placed in to 0-5 ℃ of mixture of ice and water and soaking cooling 3-5 minute, now rib nail is moulding front state, the non-blind end lateral bend slightly inwards of rib nail, and (30 °-45 °) have a certain degree;
(2) use shaping forceps that rib nail is strutted, pack into fast in the nail kit 4 of above-mentioned Wicresoft rib ail gun, guarantee that the rib nail packing into is not crooked, while injecting, rib nail can vertically be injected in rib;
(3) be ready to inject after front work, by on the rib that is pressed on the fracture vertical gun barrel 2 of Wicresoft's rib ail gun, rib injected by rib nail by moment, after injecting, can use gauze to dip in hot water (40 degree, guarantee not scalded skin) be placed on rib and nail on (object is that high temperature makes rib nail that deformation occur), then wrapping, sew up wound.
Due to fracture position and the degree difference of rib, can select different rib nail fixed forms, for example, serious used double fastening is fixed.Owing to using, ail gun transmitting rib nail fixing rib bone groove is little, does not affect outward appearance after healing, does not damage intercostal nerves and blood vessel, reduces and even avoids intercostal nerve pain, avoids damaging pleura and occurs pneumothorax, therefore has very important clinical application.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
