Description
Technical field
The present invention relates to a kind of detachable split type rongeur, belong to medical instruments field.
Background technology
In the prior art, when lumbar vertebra, thoracic vertebra or cervical vertebra are performed the operation, often need to separate, cut corner angle bone or irregular ligament are arranged, there is not special-purpose bone cutting clamp during in the past operation, but replace with general nucleus pulposus clamp, this prolongs operating time so that this separation and cutting have some setbacks very much, control force to operation process is relatively poor, processes sordid problem but also have remnant tissue.
In order to address the above problem, this case inventor once invented a kind of bone cutting clamp, it comprises fixed handle, flexible handle, claw beam, wire drawing, binding clip and movable cutting sheath, by flexible handle push away, La Lasi, control the movement of cutting sheath, thereby realize the cutting to bone, although this bone cutting clamp can quick and safe excision has the bone of corner angle, separate and cut irregular ligament, but find that in use still there are a lot of shortcomings in it.
At first, claw beam and caliper adopt integral structure, owing to need to use the bone cutting clamp of all size in the operation, therefore the bone cutting clamp of every kind of specification all needs to manufacture, and manufacturing cost is very high like this.
Secondly, most of operating theater instruments also comprises this bone cutting clamp of the initial invention of this case inventor, their body of rod all adopts metal material to make, and major part is the silvery white body of rod, in operation, find, when the silvery white body of rod is worked under mirror, can produce reflective, cause blurred vision, can affect doctor's the visual field.
In addition, the body of rod of this bone cutting clamp and caliper adopt integral structure, and the body of rod can't be rotated, and therefore need to often alter one's posture operation Shi doctor, and be very large for position difficulty when carrying out cutting operation of special angle, the success rate of impact operation.
Summary of the invention
The object of the invention is to, a kind of detachable split type rongeur is provided, it can either sharp separation, the bone that is cut with corner angle and irregular ligament, solve and use traditional cutting clamp cutting, separate the problem that has some setbacks, but also can dismantle, separate, advantage with low cost of manufacture, and can solve the reflective problem of traditional cutting clamp body of rod.
Technical scheme of the present invention: a kind of detachable split type rongeur, comprise fixed handle, flexible handle, caliper and cutting claw beam, fixed handle and caliper are the integral type structure, flexible handle and fixed handle are flexibly connected by rotating shaft, the top of flexible handle is positioned at caliper, and the top of flexible handle is provided with push rod; One end of cutting claw beam is located in the caliper.
In the aforesaid this detachable split type rongeur, the cutting claw beam is provided with black ALTIN coating.ALTIN coating is prior art, and it has firm, antirust, the surface smoothing in surface, can not produce reflective, better biocompatibility and increase the advantage in the service life of apparatus.
In the aforesaid this detachable split type rongeur, the cutting claw beam comprises the body of rod, the cutting sheath, gathering sill, rotation tuning bar, inner core and binding clip, one end of the body of rod is provided with gathering sill and binding clip, the other end of the body of rod is fixedly connected with an end of rotation tuning bar, the other end of rotation tuning bar is provided with groove, spacing regulating tank and groove, groove is positioned at a side of spacing regulating tank opening, be provided with push-pull bar in the rotation tuning bar, the cutting sheath is located in the gathering sill, inner core is located in the body of rod, one end of inner core is fixedly connected with the cutting sheath, the other end of inner core is fixedly connected with an end of push-pull bar, the other end of push-pull bar is provided with the first baffle plate, and the body of rod of push-pull bar is provided with return spring; Be provided with the positive stop that matches with spacing regulating tank in the described caliper.
In the aforesaid this detachable split type rongeur, described spacing regulating tank be shaped as " U " shape or " V " shape.
In the aforesaid this detachable split type rongeur, rotation tuning bar is provided with anti-skidding projection; The end that push-pull bar is provided with the first baffle plate also is provided with second baffle.Adopt this structure can when the one-level baffle plate damages, use immediately the secondary baffle plate, can not occur because the one-level baffle plate damages the thing that causes operation to interrupt.
In the aforesaid this detachable split type rongeur, the body of rod is provided with scale, and the body of rod is provided with 1～5 identification rings with the end that rotation tuning bar is connected.Identification rings is set can make the doctor can be fast and find out accurately the cutting claw beam of own needed specification; Safety and success rate that scale can improve operation are set.
