Abstract
The invention belongs to the field of medical instruments, and provides a clamping and shearing device for the newborn umbilical cord. The clamping and shearing device comprises two forceps bodies hinged through a hinging shaft. An umbilical cord clamp, a blade and another umbilical cord clamp are sequentially arranged in a jaw of each forceps body from one side of the jaw to the other side of the jaw. The blades cut the umbilical cord when the umbilical cord clamps clamp the umbilical cord or after the umbilical cord clamps clamp the umbilical cord, the umbilical cord clamps are locked through mutual locking structures, and the two umbilical cord clamps of each forceps body clamp the two ends of the shorn portion of the umbilical cord respectively. The umbilical cord clamps are separated from the jaws through the pushing effect on umbilical cord clamp connecting ribs from the front ends of elastic strips. The connecting ribs are provided with protruding edges, and the protruding edges limit the elastic strips when the elastic strips push the umbilical cord clamps so as to guarantee that the force application position is reliable. Reinforcing ribs are arranged on the outer side surfaces of clamping arms of the umbilical cord clamps, and therefore the strength of the umbilical cord clamps is fully guaranteed, the strength of the clamping movement of the umbilical cord clamps can be effectively guaranteed, and deformation does not occur easily. The clamping and shearing device for the newborn umbilical cord is reasonable in structure and convenient to use and greatly shortens the ligation time of the umbilical cord.

The specific embodiment
As shown in Figure 2, neonatal umbilical cord tongs device of the present invention, comprises that two by the hinged caliper 1 of jointed shaft 7, and the interior side direction opposite side along jaw of jaw 2 of caliper is provided with umbilical clamp 4, blade 5 and umbilical clamp (in figure, only illustrate a side umbilical clamp) successively.
On two forward surfaces of jaw 2, be respectively arranged with blade 5, these two blades form scissor construction, or, on a forward surface of jaw 2, be provided with blade 5, and correspondence position on another forward surface is provided with chopping block 6, what in figure, provide is the structure that blade 5 coordinates with chopping block 6.
Two jig arm of umbilical clamp 4 connect by dowel 41, dowel 41 bottoms are provided with a fin 42, on the medial surface of two jig arm, be provided with the structure being mutually locked, the structure being mutually locked can be tooth bar 49 and the closing component structure that forms with the perforation 40 of tooth bar engagement, or the closing component structure that sour jujube hook 47 and sour jujube hook groove 48 form, or the two is in conjunction with the closing component structure forming.Preferably tooth engaging conformation and sour jujube hook, sour jujube hook groove structure are applied jointly.The fixedly locking structure of umbilical clamp head end can be strengthened tooth engagement, can effectively prevent the possibility that umbilical clamp comes off fixedly time, and closure is more fastening, can effectively prevent from coming off because of the umbilical clamp that baby moves or other actions cause.The front end of jig arm lateral surface is provided with front card column 43, and rear end is provided with rear card column 46, correspondingly, and card column groove 21 and rear card column groove 22 before jaw 2 front-end and back-end are respectively arranged with.In jig arm outside, near front card column 43 ends, be provided with bumping post 45.
In rear end, caliper hinged place, be provided with dowel storage tank 9, the bottom jagged 91 of dowel storage tank 9, side handle 3 inner sides at caliper are provided with elastic strip 10, during use, the front end of elastic strip 10 is positioned at dowel storage tank bottom notch 91, in the inner side of the opposite side handle corresponding with elastic strip protuberance, is provided with block 8, and the preferred stop block structure of the present invention itself and elastic strip 10 protuberance contact surfaces are plane 81, plane 81 outsides are provided with boss 82, and rear end is provided with bucking ladder 83.
Before use, the angle between two jig arm of umbilical clamp 4 is less than or equal to two angles between blade or the angle between blade 5 and chopping block 6; In use, blade 5 is when umbilical clamp 4 clamps umbilical cord or cut off afterwards umbilical cord, and the structure that umbilical clamp 4 is mutually locked by it is sealed; Elastic strip 10 front ends throw off umbilical clamp 4 and jaw 2 to the impetus of umbilical clamp dowel 41.
On jig arm lateral surface, be provided with reinforcement 44, reinforcement 44 is by jig arm middle part attenuation gradually to both sides.Reinforcement fully guarantees the intensity of umbilical clamp own, can effectively guarantee the dynamics of umbilical clamp when clamping is moved, can not be out of shape easily, and reinforcement by jig arm middle part to both sides gradually attenuation be beneficial to saving material meeting intensity simultaneously.
As a kind of preferred structure, on handle 3, be provided with anti-slip veins 31 or anti-skidding encapsulate.
Laborsaving for tongs device is used, jointed shaft 7 compares for 1.8-2.2 with the distance of jointed shaft 7 apart from jaw 2 tops apart from the distance of handle 3 ends.The reasonably arm of force and moment ratio, in the situation that handle is applied to equal dynamics, can be stronger carry out tongs action, more laborsaving.
Principle of the present invention is identical with disposable umbilical cord shears in CN1689532A, but is provided with fin structure in the dowel bottom that connects two jig arm of umbilical clamp, and fin has certain position-limiting action to promoting the elastic strip front end of umbilical clamp; Block and elastic strip protuberance contact surface are plane, plane outside is provided with boss, rear end is provided with bucking ladder, when closed two handle, elastic strip lobe is supported in the plane, boss has restriction to the elastic strip being in contact with it, the inclined-plane of rear end bucking ladder is higher than plane, when elastic strip protuberance and plane contact, elastic strip protuberance rear end contacts with the inclined-plane of bucking ladder, three's combined effect, in handle closing course, make the crimp of elastic strip rapidly, reliably, elastic strip promotes forward umbilical clamp, makes umbilical clamp and jaw separating effect reliable.Meanwhile, the reinforcing rib structure of umbilical clamp is further optimized clamping effect, and Umbilical cord pliers device of the present invention is applicable to neonatal umbilical cord ligation operation, simple to operate, reliable for effect.
