Description
Technical field
This utility model relates to a kind of orthopedic devices, particularly relates to a kind of bone holding forceps.
Background technology
Time clinically to its cadre of long bone fracture or its free-end fracture and the treatment of small size bone transverse fracture, all need first to carry out the reduction of the fracture and fixing.Reset and fixing to successive treatment normally carry out and surgical quality tool has a significant impact.At present in the reduction of the fracture and fixing operation, medical personnel need to use bone holding forceps, bone holding forceps are generally made up of along the arc binding clip connect two clamp handles be hinged and its front end, but existing binding clip is made by rigidity material, its surface is hard smooth, easily skid, if misoperation also easily scratches periosteum when clamping key.In addition, need special messenger to grip clamp handle to be fixed in operation always, its fatigue strength is large, and existing clamp handle is ganoid arc, and hand easily slides, it grips shakiness, not only be unfavorable for fixing, also easily make backbone get loose on binding clip, time serious, can fracture and injury be increased the weight of, extend operating time, add the misery of patient.Some patents are had to have made some improvements for these shortcomings, " a kind of Diaphysis bone holding forceps " that be CN203107215U as grant number is provided with ratchet and pawl arrangement to make clamping be stabilized in caliper hinged place, but because the radius of ratchet is much smaller than jaw length, therefore the program has open defect, one is that stressed can the amplification at jaw place much doubly passes to click, two is that ratchet often rotates a tooth, and jaw opens much larger times of distance meeting.Also there are some schemes that clamp handle position is provided with bolt thread and assist regular jaw opening angle, this scheme needs a hands knob bolt adjustment, because point breaking up of operator's attention destroys the stressed size sensation of holding that hand of clamp handle, also comparing can be time-consuming, cumbersome.
Utility model content
This utility model is for the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, and staff can be helped the bone holding forceps of the stable holding of skeleton.
To achieve these goals, this utility model provides a kind of bone holding forceps, and comprise the caliper that both sides are hinged in jaw and clamp handle crossover position, described clamp handle is hinged with tooth bar, curved and its camber line of described tooth bar with caliper hinged place for the center of circle; Clamp handle described in another side is provided with the through hole for making described tooth bar pass, clamp handle described in this is positioned at described lead to the hole site and is provided with key seat, described key seat is connected with the ejector pin coordinated with described tooth bar, the described ejector pin other end is connected with spring, and the described spring other end is connected with clamp handle described in this or key seat; Described ejector pin is provided with and pushes away handle.
Wherein, rubber sheet gasket is provided with inside described jaw
The toothed side of described tooth bar is towards jaw.
During work, staff holds this programme clamping skeleton, and thumb pushes handle open makes ejector pin depart from tooth bar, and be adjusted to according to feel and need clamping degree, thumb unclamps, and ejector pin is combined with tooth bar and namely grips.
The beneficial effect of this programme can be learnt according to describing of such scheme, and structure is simple, reasonable in design, adopts the lockable mechanism of ejector pin and tooth bar, flexibly and easily, staff can be helped the stable holding of skeleton.Curved and its camber line of tooth bar for the center of circle, makes tooth bar not interfere with clamp handle in jaw opening and closing process with caliper hinged place.The position of ejector pin and ejector pin arrange and push away handle, be conducive to staff hold with a firm grip clamp handle time, thumb can also push away handle by flexible operating, meets ergonomics.Inside jaw, rubber sheet gasket is set, first clamping dynamics can be made to become stepless changing from the level adjustment that has of simple tooth bar, secondly periosteum injury can be avoided, moreover due to sheet rubber be that elastic material can increase skeleton lifting surface area, thus gross pressure suffered by skeleton can be increased, add that quality of rubber materials coefficient of friction is comparatively large, can significantly improve frictional force between jaw and skeleton.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model detailed description of the invention;
In figure, 1, jaw; 2, clamp handle; 3, tooth bar; 4, key seat; 5, ejector pin; 6, spring; 7, handle is pushed away; 8, rubber sheet gasket.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, this programme is set forth.
As shown in Figure 1, this utility model is a kind of bone holding forceps, and comprise the caliper that both sides are hinged in jaw 1 and clamp handle 2 crossover position, clamp handle 2 is hinged with tooth bar 3, curved and its camber line of tooth bar 3 is with caliper hinged place for the center of circle, and the toothed side of tooth bar 3 is towards jaw 1.Another side clamp handle 2 is provided with the through hole for making tooth bar 3 pass, and this clamp handle 2 is positioned at lead to the hole site and is provided with key seat 4, and key seat 4 is connected with the ejector pin 5 coordinated with tooth bar 3, and ejector pin 5 other end is connected with spring 6, and spring 6 other end is connected with key seat 4; Ejector pin 5 is provided with and pushes away handle 7.Rubber sheet gasket 8 is provided with inside jaw 1.
During work, staff holds clamp handle 2 and clamps skeleton, and thumb pushes handle 7 open makes ejector pin 5 depart from tooth bar 3, and be adjusted to the clamping degree of needs according to feel, thumb unclamps, and ejector pin 5 is combined with tooth bar 3 and namely grips.
This utility model can pass through without the technical characteristic described or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; this utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
