Description
Technical field
The invention belongs to surgical instruments equipment technical field, is specifically a kind of deep depth measurement bone drill of limit.
Background technology
Bone drill is instrument boring on bone in surgical operation.When drilling on bone, surgical doctor electric hand drill, adds
Pressure pierces.After bone drill breaks through sclerotin completely, electric drill falls through, and surgical doctor can not possibly stop pressurizeing at the same time, thus cause electric drill
Continue deeper into forward.Deeply during may cause tissue damage, if electric drill direction of advance there are blood vessel, nerve when, once
Damage, will lead to grave consequences.And being drilled behind hole also needs the depth that measurement drills to determine appropriate screw.And existing bone drill
Only there is drilling, surgical doctor needs to be measured with bathometer insertion drilling after piercing.
The content of the invention
The present invention may cause to damage to solve existing bone drill to soft tissue and nervus vasculairs, and function is single, bore
The problem of hole and depth measurement need separately to carry out, there is provided the deep depth measurement bone drill of one kind limit.
The present invention takes following technical scheme:The deep depth measurement bone drill of one kind limit, including drilling rod, further include opposite drilling steel slip
, can brake at any time and can limited cripetura protective case, and can show display machine of the protective case with respect to drilling steel slip distance
Structure.
The protective case includes leading portion and back segment, and limited cripetura structure is set between leading portion and back segment, described limited short
The elastic structure and the limit of limitation elastomer structure deflection connected between shrinking structure, including leading portion tail end and back segment front end
Position mechanism.
Connecting spring between leading portion tail end and back segment front end, the position-limit mechanism include and protective case back segment front periphery
Segment trailer is arranged within stop collar before the stop collar of threaded connection, spring and protective case, there is outside annular segment trailer before protective case
There are an annular inner convex platform in boss, stop collar front end, and boss, which is formed, inside and outside annular coordinates.
Sheath is provided with after the protective case outside segment trailer, brake apparatus is set between sheath and protective case back segment,
The sheath at brake apparatus rear is equipped with the position-limit mechanism of protective case.
The brake apparatus includes the brake hoop of sheath and protective case back segment, brake hoop inner wall and protective case back segment outer wall it
Between, between brake hoop outer wall and jacket inner wall leave gap, between the wall thickness central and sheath and protective case back segment of brake hoop between
The center of gap coincide, and the brake handle radially set is connected with brake hoop.
The brake apparatus includes the latch segment to rotate to it that sheath is set, and latch segment, which is equipped with, can make latch segment
The steel sheet spring of reset, latch segment top can be contacted on the periphery of protective case back segment, and the latch segment other end connects brake handle.
The resetting-mechanism of protective case is provided between protective case and sheath.
The resetting-mechanism includes the guide nut for being fixed on guard leading end, is connected between guide nut and stop collar
Resetting spring.
Segment trailer is provided with guide pad after the protective case, and guide pad can be slided along jacket inner wall, in front of guide pad, makes
The position-limit mechanism that spacing pin is guide pad is set on the sheath at dynamic device rear, sheath tail end branch sleeve, be in sleeve with
The driving mechanism of drilling rod connection.
The driving mechanism is equipped with the trigger for starting, and brake handle is arranged in front of the trigger of driving mechanism,
The dead-centre position of brake handle movement can cocking.Brake handle can brake sleeve when pulling, and continue to pull then
Electric drill can be started.Realize flexible manipulation of the single finger to electric drill.
The course of work:Drilling rod and protective case are butted on bony surface, and protective case scale is 0 scale at this time.Motor starts, drilling rod
Bone first layer is pierced, protective case integrally retreats.Rod boring first layer sclerotin, is butted on second layer sclerotin, and motor stops, braking
Handle braking(Protective case back segment stops retreating).Motor is started again, and drilling rod continues to creep into, and the stroke of drilling is limited for protective case
The length of shortening, drilling machine stop.If the drill-through second layer sclerotin of drilling rod, surgical doctor holds brill hand and has the obvious sense that falls through,
Drilling stops.Directly read protective case sliding distance opposite with drill body, you can know that brill gos deep into length, and can select accordingly properly
The screw of length.If drilling rod is not drill-through, braking is released, drilling rod leading portion resets, and motor starts, before drilling rod creeps into a drilling rod again
The length of section cripetura, motor are closed.So repeatedly, until the drill-through second layer sclerotin of drilling rod, surgical doctor, which holds brill hand, to be had substantially to fall
Sky sense, drilling stop.Directly read protective case sliding distance opposite with drill body, you can know that brill gos deep into length, and can select accordingly
Select the screw of appropriate length.
Compared with prior art, the present invention is provided with the movable drill bushing that can be braked at any time and peaks at bone surface, and after braking
Can elastical retraction certain distance, it is deep so as to fulfill spacing precision auger.It ensure that the soft tissue in human body and nervus vasculairs are boring bone
During drilling rod will not be subject to unexpectedly to damage.
And the depth for piercing bone can directly be read by the relative displacement between overcoat and drilling rod from the scale on outer set,
The step of eliminating independent measurement drilling depth, simplifies workflow.
