Description
Technical field
The present invention relates to a kind of detachable split type rongeur, belong to medical instruments field.
Background technology
In prior art, when lumbar vertebra, thoracic vertebra or cervical vertebra are performed the operation, frequent needs are separated having corner angle bone or irregular ligament, cut, special bone cutting clamp is not had during operation in the past, but replace with general nucleus pulposus clamp, this makes this separation and cutting have some setbacks very much, extends operating time, poor to the control force of operation process, but also have remnant tissue and process sordid problem.
In order to solve the problem, 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, pushed away by flexible handle, La Lasi, control to cut the movement of sheath, thus realize the cutting to bone, although this bone cutting clamp can fast and the excision of safety has the bone of corner angle, being separated and cutting irregular ligament, but in use finding, still there is a lot of shortcoming in it.
First, claw beam and caliper adopt integral structure, and owing to needing the bone cutting clamp using all size in operation, therefore the bone cutting clamp of often kind of specification all needs to manufacture, and such manufacturing cost is very high.
Secondly, major part operating theater instruments also comprises this bone cutting clamp that inventor invents at first, their body of rod all adopts metal material to make, and major part is the silvery white body of rod, find in operation, when the silvery white body of rod works under mirror, can produce reflective, cause blurred vision, the visual field of doctor can be affected.
In addition, the body of rod and the caliper of this bone cutting clamp adopt integral structure, and the body of rod cannot rotate, and therefore need often to alter one's posture operation Shi doctor, and the position difficulty when carrying out cutting operation for special angle is very large, 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 being cut with corner angle and irregular ligament, solve and use the cutting of traditional cutting clamp, be separated the problem had some setbacks, but also can dismantle, be separated, there is the advantage of low cost of manufacture, and the reflective problem of traditional cutting clamp body of rod can be solved.
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 integral type structure, flexible handle is flexibly connected by rotating shaft with fixed handle, 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 caliper.
In aforesaid this detachable split type rongeur, cutting claw beam is provided with black ALTIN coating.ALTIN coating is prior art, and it has hard-surface, antirust, surface smoothing, can not produce reflective, better biocompatibility and increases the advantage in service life of apparatus.
In aforesaid this detachable split type rongeur, cutting claw beam comprises the body of rod, cutting sheath, gathering sill, rotate 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 the one end rotating tuning bar, the other end rotating tuning bar is provided with groove, spacing regulating tank and groove, groove is positioned at the side of spacing regulating tank opening, rotate in tuning bar and be provided with push-pull bar, cutting sheath is located in gathering sill, inner core is located in the body of rod, one end of inner core is fixedly connected with cutting sheath, the other end of inner core is fixedly connected with one end of push-pull bar, the other end of push-pull bar is provided with the first baffle plate, the body of rod of push-pull bar is provided with return spring, the positive stop matched with spacing regulating tank is provided with in described caliper.
