Development in more than 20 years, Europe, the United States, Deng developed country have developed a plurality of robot for orthopaedic surgery, and the Mazor that Israel develops is main
For being placed in pedicle screw, French ROSA is suitable for the outer operation of opening cranium of mind, and the MAKO plasty in the U.S. is then used for hip knee
Joint replacement.The idicatio of robotic surgery constantly extends, and clinical operation effect is excellent in.
2016, system is positioned by the 3rd generation orthopedic navigation of Beijing Tian Zhihang medical science and technology Co., Ltd independent research manufacture
(Phegda robot for orthopaedic surgery) acquisition CFDA certification of uniting lists, a variety of operations such as achievable backbone, pelvis, limbs fracture,
It is international first universal robot for orthopaedic surgery.The position error of Phegda robot for orthopaedic surgery reaches 0.8 millimeter, is in generation
Boundary's advanced level has a clear superiority to invasive surgery formula, high risk zone, can effectively reduce operation risk, reduces operation concurrently
Disease.
Orthopedic navigation positioning system is made of mechanical arm host, optical tracking system, master control trolley.With medicine such as x-ray, CT
It based on image data, with virtual reality technology, is tracked by optical orientator, establishes a virtual ring in a computer
Border shows positional relationship of the surgical instrument relative to pathological tissues, thus realize the guiding in real time to whole process of operation, auxiliary doctor
The raw medical system for completing surgery planning and operating process in high quality.According to its design principle, when use, needs to show patient
Track device is stably fixed on operative region on bone tissue, for example, ipsilateral anterior superior spine, spinal operation are fixed in neck of femur operation
It is fixed on neighbouring section centrum spinous process), which requires operative site sustainedly and stably to fix in the course of surgery, and exists and increase
The drawbacks of adding additional surgical notch, therefore it is still dfficult to apply to wrist portion operation at present.
The advantages that wrist portion dissection is complicated, and functional requirement is higher, and robotic assisted surgery is minimally invasive, accurate is applied to wrist portion
Operation has good advantage, fixes as fracture of scaphoid Herbert is followed closely.But it needs to solve to stablize fixed wrist portion, determine patient
Tracer fixes the problem of position.
Utility model content
The goal of the invention of the utility model is: in view of the above problems, providing a kind of orthopedic navigation positioning system
With wrist fixed frame is applied, can solve the problems, such as to stablize fixed wrist portion, while also solving determining patient's tracer fixed bit
The problem of setting.
The technical solution adopted in the utility model is such that
A kind of orthopedic navigation positioning system is with applying wrist fixed frame, including bottom plate, and plate upper surface is by palm fixed area
Domain is divided into thumb area, four finger regions, centre of the palm region and wrist area totally four regions, and the thumb area is in itself and centre of the palm area
Intersection setting thumb clamping plate in domain is simultaneously fixed on bottom plate against thumb area two sides by thumbscrew board ends are detachable, described
Four refer to that region refers to clamping plate with centre of the palm region intersection setting four at it and refers to that region two sides refer to that clamping plate both ends are removable for four against four
The formula of unloading is fixed on bottom plate, and the wrist area is arranged wrist clamping plate with centre of the palm region intersection at it and abuts wrist area two
Side is fixed on wrist clamping plate both ends are detachable on bottom plate.
Preferably, patient's tracer connector is installed at four angles of the bottom plate.
Preferably, patient's tracer connector includes the preformed hole opened up on bottom plate and matched with its two
Patient's tracer can be stably fixed on bottom plate by root butterfly screws.
Preferably, the four fingers clamping plate, wrist clamping plate, thumbscrew board ends pass through clamping plate connector respectively and are fixed on bottom
On plate.
Preferably, the bottom plate, four finger clamping plates, wrist clamping plate and thumb clamping plate are all made of the manufacture of peek plastics.PEEK
Plastics (polyether-ether-ketone resin) are a kind of special engineering plastics haveing excellent performance, and are had compared with other special engineering plastics more
Significant advantage, resistance to 260 degree of positive high temperature, mechanical performance is excellent, and self-lubrication is good, and chemicals-resistant burn into is fire-retardant, peel resistance, resistance to
Mill property, it is very prominent intolerant to strong nitric acid, the concentrated sulfuric acid, radiation resistance.The utility model uses there are two the purposes of peek plastics:
One, saturating x-ray does not influence the imaging of operative site bone tissue x-ray；Two, high temperature high voltage resistant, can be through high-temperature sterilization the characteristics of.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are: wrist can be stablized solid
It is fixed, it avoids being displaced in acquisition image or operative process, structure is simple, and it is easy to use, it is practical, it can be with bone guide
Boat positioning system matches.
