Description
Technical field
The present invention relates to a kind of operating theater instruments suitable for bone surface being repaired operation camber structure.
Background technology
At present, domestic and international plastic surgery, Orthopedic Traumatology etc. are required for carrying out detailed finishing to the surface of skeletal structure, with
Adapt to the attachment of tendon, muscle and soft tissue.Bone face, the personalization of 3D printing of finishing arc are particularly needed in plastic surgery
Implant needs have good matching etc. with bone face when hone lamella is implanted into, it is therefore desirable to which bone structure is repaired accordingly.
And in medicine equipment, the blades of most of cutters be it is plane, as the scalpels such as J12090 10#, J12100 11# blade all
It is plane, even if as J12110 12# scalpels, although tip shapes are L shapes, blade is still plane.For needing
It is for arc-shaped curved surface to repair skeletal structure, and accuracy of the planar edge when cutting off compact bone substance and cancellous bone is very poor, causes
Sclerotin body is cut off too much, can extend the recovery time of postoperative patient.
The content of the invention
3D printing technique is in terms of medical orthopaedics implant using increasingly wider, the hone lamella reconstruction after tumor resection, foot
Surface modeling of bone plate designs, prosthetic surface during joint fusion etc. is, it is necessary to match the surface modeling of personalized hone lamella and prosthese
Design.And from medical image to structure design, again to during prosthetic designs, the reality of actual implant shape and bone surface
There is error in profile, it is therefore desirable to which the irregular contour of bone surface is repaired.Repaired with the planar edge of scalpel
Bone surface, it is difficult to ensure the irregular contour of bone surface.
The purpose of patent of the present invention is irregular contour, 3D printing hone lamella and the bone table for being directed to bone surface in plastic surgery
Bone surface finishing during face curvature inconsistency, there is provided a kind of applicable medicine equipment simple in construction, convenient, for accurate in operation
Really finishing bone surface profile.
A kind of according to an aspect of the invention, there is provided operating theater instruments for repairing bone arcwall face, it is characterised in that bag

Embodiment
It is an object of the invention to provide a kind of operating theater instruments for repairing bone arcwall face, that is, provide a kind of shaping teacher or surgery
Doctor can easily dismantle, ergonomic coordinates excellent, the multiduty medicine equipment for repairing bone face.The medicine equipment can
It is arcuate structure for repairing bone face.
As shown in figs 1-9, the medicine equipment includes cutter head and handle of a knife.Cutter head includes curved blade 1, broached-tooth design 2, spring
3rd, the embedded T-shaped connection top 4 of cutter head afterbody, the embedded T-shaped connection bottom 5 of cutter head afterbody.Wherein, the radian of curved blade 1
The arcuate structure of Multiple Type can be designed to according to the amount of curvature of bone surface, when being easy to repair bone face with bone surface very
It is bonded well；Secondly, when needing to repair the larger bone face of thickness, broached-tooth design 2 can be used to carry out the finishing of sawing and handled；
Spring 3 is easy to disassemble and clamping；The T-type structure connection top 4 and connection bottom 5 of cutter head afterbody can accurately be embedded in handle of a knife
In, installation and removal are convenient and swift.On handle of a knife, the ergonomics of cutter are held according to shaping teacher or surgeon, design hand
Portion's thumb and other four grasping directions referred to, prevent the discomfort of hand when handle of a knife comes off and prevents long-term use during operation；Its
Secondary, handle of a knife can also match the percussion hammer in medicine equipment, the propulsive force of increase finishing bone.
Handle of a knife includes toolholder body 8 and handle of a knife front end 6, as shown in Figure 4 and Figure 5.
The cutter head and handle of a knife material of described finishing bone arcwall face are stainless steel, can disinfect and prevent repeatedly
Got rusty caused by Reusability.Cutter head accurate measurement can be designed to different size of curved blade according to bone face curvature, knife
The scope of shank diameter is 3~3.5cm, is easy to shaping teacher or surgeon to grasp, its structure design meets the posture feature of hand.
Its thumb grip 7 and four, which refers to grip 9, to be set according to Chinese adult finger average length and width progress structure
Meter.
The operating theater instruments overall structure of described finishing bone arcwall face is stainless steel, and no other materials uses.According to figure
The assembly relation of embodiment shown in 1-9, spring and cutter head afterbody is：Four springs 3 half are forced, and to be installed into cutter head afterbody embedding
Enter the corresponding position between the top 4 and bottom 5 of the T-shaped connection of formula, so that the coupling part 4 and 5 of cutter head afterbody is embedded in knife
Handle, i.e., under the active force of spring 3 in the T-slot of cutter head afterbody insertion handle of a knife front end 6 (Fig. 4)；When dismantling or changing cutter head,
By pressing the embedded T-shaped connection top 4 of cutter head afterbody and the embedded T-shaped connection bottom 5 of cutter head afterbody so as to extrusion spring 3,
Cutter head is pulled down from the T-slot of handle of a knife front end 6；It is convenient and swift so as to which free handling can be realized.
According to one embodiment of present invention, the operating theater instruments of described finishing bone arcwall face includes cutter head and handle of a knife two
Part.Wherein the curved blade 1 of cutter head can be according to different bone curved surfaces, and being processed into the blade size of different radians (can divide a variety of
Model).To be processed and formed at one time, thumb grip 7 and four refers to grip 9 and accorded with for overall handle of a knife front end 6 and toolholder body 8
Close the anatomical features that human body refers to portion.
Specific installation, use and demolition process：
Installation process includes：Take on the other hand at the half of cutter head intermediate region, make the axis and Fig. 4 of cutter head shown in Fig. 1
The axis of shown handle of a knife is point-blank.The embedded T-shaped connection top 4 of cutter head afterbody and cutter head afterbody is embedded T-shaped
The T-slot hole of connection bottom 5 and handle of a knife front end 6 is assembled together, untill when can not continue into.
Included using process：Handle of a knife is held, thumb is in thumb grip 7, and other four fingers is in four
Refer to the position of grip 9, exert oneself vertically to repair bone surface.If bone cortex bone is too thick, can be entered by broached-tooth design 2
The processing of row dragsaw sawing, is then repaired with curved blade 1 again；To increase finishing dynamics, it is also possible to tap hammer and tap handle of a knife
The plane of afterbody.
Unloading process：When needing to dismantle or change the cutter head of different radians, one holds toolholder body 8, and the other end presses push type broach
At where two springs 3 of head front end, while apply withdrawal force, you can separation cutter head and handle of a knife, realize dismounting or change.
