Description

Detachable split type rongeur

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.

In the aforesaid this detachable split type rongeur, the body of rod is provided with 3 identification rings with the end that rotation tuning bar is connected.

In the aforesaid this detachable split type rongeur, binding clip is facet with the contacted one side of cutting sheath, and the cutting sheath is provided with the cutting edge that matches with facet with the contacted one side of binding clip.

In the aforesaid this detachable split type rongeur, the angle a of facet and horizontal plane is 20 °～90 °.

In the aforesaid this detachable split type rongeur, the angle a of facet and horizontal plane is 60 °.

In the aforesaid this detachable split type rongeur, the middle and upper part of fixed handle is provided with pin, and the outside of fixed handle is provided with antiskid groove.Pin and antiskid groove are set can be made the doctor hold when pincers more steady preventing to skid.

In the aforesaid this detachable split type rongeur, the length of the body of rod is 10cm～60cm, and the diameter of the body of rod is 2mm～6mm.

In the aforesaid this detachable split type rongeur, the length of the body of rod is 30cm, and the diameter of the body of rod is 4mm.

Compared with prior art, the present invention adopts split-type structural, and the cutting claw beam can separate with caliper, when therefore needing to use the rongeur of different length and diameter, only need to change the cutting claw beam and get final product, can save so a large amount of production materials, reduce the production cost of apparatus.

Because be provided with gathering sill and cutting sheath, the cutting sheath slides in gathering sill, realizes the movement of horizontal direction, such move mode is larger than the binding clip cutting dynamics that traditional cutting clamp rotates centered by axle, makes cutting more smooth and easy, more possesses handling.Because the cutting sheath that adopts this horizontal direction to slide makes the jaw of cutting clamp larger, working range is wider, can separate like a cork, be cut with corner angle bone or irregular ligament, effectively shortens operating time, improves the success rate of operation, reduces the risk of operation.

In addition, the body of rod of the present invention is provided with black coating, can be not reflective when the present invention is worked under mirror, and safety and the success rate of Effective Raise operation.

The present invention has not only adopted split-type structural, owing to be provided with the parts such as rotation tuning bar, spacing regulating tank, return spring, pin, cutting claw beam of the present invention can be rotated by 360 degree, therefore when being performed the operation, the special angle position can easily adjust the direction of cutting claw beam cutting sheath, the doctor can be performed the operation to privileged sites easily, success rate of operation is improved greatly.
