Abstract
The invention relates to the technical field of medical instruments, in particular to a device for cutting bones in surgical operations, especially orthopedics operations. The replaceable sliding hammer power osteotome (bone knife) is composed of a sliding hammer and an osteotome (bone knife) and is disassembled and combined by screws; on the premise that the tail of the osteotome (bone knife) conforms to the design requirement of the osteotome (bone knife), the blade of the osteotome (bone knife) can be designed into different widths, radians, bending angles and the like according to the clinical requirement, thereby bringing convenience to use. According to the device, the blade direction of the osteotome (bone knife) can be accurately controlled; a cylindrical hammer part can finish the operation of knocking each time along a slide bar. If the blade of the osteotome (bone knife) is clamped and pressed in the bone and is difficult to pull out, the cylindrical hammer part knocks a clamping nut far away from the osteotome (bone knife) along the slide bar, and thus the osteotome (bone knife) can be quickly and conveniently pulled out.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of particularly equipment of the deep bone of bone surgery cutter of surgery that is used for.
Background technology
The unpowered device of osteotome (cutter) itself that section particularly uses in the bone surgery that is out at present needs to use hammer and knock its afterbody and produce the effect that strength plays the deep bone of cutter.Operator needs both hands to hold osteotome (cutter) and hammer respectively in the use, wayward strength and the direction of knocking, just may occur hammer when occurring other situation attention diversion in the art with person or operator does not hit osteotome (cutter) afterbody and knocks operator situation on hand, so not only injure operator, and might hide and cause the displacement suddenly of osteotome (cutter) tip end cutting to injure important adjacent tissue because operator grasps the injured hands of osteotome (cutter), as injuring the dural sac spinal cord in the spinal operation, nerve rooies etc., serious and irreversible damages such as quadriplegia then may appear in patient.
Tradition osteotome (cutter) is knocked to enter and is extracted difficulty when sclerotin is pressed tightly than dark or card when getting bone, often need multi-direction swing to take out, may cause beyond thought fracture during swing, get the bone piece and be extruded the situation such as influence use etc. that diminishes, even need other places to get bone again, caused unnecessary misery to patient.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of changeable type sliding hammer power osteotome (cutter) that can use safely is provided.
Technical scheme of the present invention is achieved in that changeable type sliding hammer power osteotome (cutter), is made up of sliding hammer and osteotome (cutter).Sliding hammer is made up of sliding bar, binding nut, cylindrical shape hammer portion, and there is pin thread at the sliding bar two ends, the long 25cm of sliding bar, sliding bar diameter 1cm, binding nut diameter 4cm, the binding nut periphery is provided with concavo-convex twill can increase frictional force, can reach big torsion with the finger rotation.Osteotome (cutter) is made up of blade, handle portion, afterbody, handle portion, afterbody are hexagon, handle portion, afterbody total length are not less than 12cm, the afterbody center is provided with female thread along the handle portion long axis direction, the pin thread at female thread and sliding bar two ends is complementary and can screws mutually, be provided with annular recess around the female thread of afterbody, can avoid being subjected to the screw-in that percussion power quantitative change shape influences pin thread because of the female thread edge.
Advantage of the present invention is:
The sliding hammer of changeable type sliding hammer power osteotome (cutter) and osteotome (cutter) can be by screw dismounting combinations, and the total length of dismounting back changeable type sliding hammer power osteotome (cutter) meets the length restriction standard of operating theater instruments sterilization treatment.
The sliding hammer of changeable type sliding hammer power osteotome (cutter) and osteotome (cutter) can be by screw dismounting combinations, osteotome (cutter) afterbody meets that its blade can be designed to different width, radian, angle of bend etc. according to clinical needs under the prerequisite of designing requirement of the present invention, and is easy to use.
The sliding hammer of changeable type sliding hammer power osteotome (cutter) and osteotome (cutter) are connected as a single entity, and sliding bar is consistent with osteotome (cutter) handle orientations, but both hands are accurately controlled osteotome (cutter) blade direction; Cylindrical shape hammer portion knocks all at every turn and can accurately finish along sliding bar, can avoid traditional hammer not hit osteotome (cutter) afterbody and accidentally injure the situation that operator is held osteotome (cutter) hands, avoid operator to hide the situation that the displacement suddenly of osteotome (cutter) tip end cutting injures important adjacent tissue that occurs because of hand.
Get in the osseous surgery when changeable type sliding hammer power osteotome (cutter) is knocked and enter the dark or card of sclerotin and press when tight, hammering cylindrical shape into shape portion knocks to the binding nut away from osteotome (cutter) along sliding bar, withdrawal force can be transmitted to osteotome (cutter) and blade thereof along sliding bar, extract osteotome (cutter) easily and efficiently, can avoid multi-direction swing causes when extracting osteotome (cutter) accident fracture, get the bone piece and be extruded the situations such as influencing use that diminishes, save operating time, reduced patient's misery.

The specific embodiment
Changeable type sliding hammer power osteotome (cutter) is made up of sliding hammer 1 and osteotome (cutter) 2.Sliding hammer 1 is made up of sliding bar 3, binding nut 4, cylindrical shape hammer portion 5, and there is pin thread 6 at sliding bar 3 two ends, sliding bar 3 long 25cm, sliding bar 3 diameter 1cm, binding nut 4 diameter 4cm, binding nut 4 peripheries are provided with concavo-convex twill can increase frictional force, can reach big torsion with the finger rotation.Osteotome (cutter) 2 is made up of blade 7, handle portion 8, afterbody 9, handle portion 8, afterbody 9 are hexagon, handle portion 8, afterbody 9 total lengths are not less than 12cm, afterbody 9 centers are provided with female thread 10 along handle portion 8 long axis directions, female thread 10 is complementary and can screws mutually with pin thread 6, be provided with annular recess 11 around the female thread 10 of afterbody 9, can avoid being subjected to the screw-in that percussion power quantitative change shape influences pin thread 6 because of female thread 10 edges.
At first select the suitable osteotome (cutter) 2 of blade 7 when using in the operation for use, the pin thread 6 of sliding hammer 1 is screwed in the female thread 10 of osteotome (cutter) 2, rotating clamp jack panel 4 makes sliding bar 3 be connected closely with osteotome (cutter) 2 again.Operator does not reach in the operation concrete needs cutter according to right-hand man's advantage custom, place operating field side and cuts the position and determine that the right-hand man holds handle portion 8 or cylindrical shape hammer portion 5 respectively, both hands hold respectively cutter butt that handle portion 8 and cylindrical shape hammer portion 5 control osteotome (cutter) 2 to, hammer cylindrical shape into shape portion 5 and knock to the binding nut 4 that osteotome (cutter) 2 connects along sliding bar 3, the blade 7 that percussion power is transmitted to osteotome (cutter) 2 plays the effect of cutting of cutting a hole.If blade 7 cards are pressed on when being difficult to extract in the skeleton, to hammer cylindrical shape into shape portion 5 and knock to binding nut 4 away from osteotome (cutter) 2 along sliding bar 3, withdrawal force can be transmitted to osteotome (cutter) 2 and blade 7 thereof along sliding bar 3, extracts osteotome (cutter) 2 easily and efficiently.
