Description

Operation tridimensional orienting headstock

Technical field

The utility model is related to medical fields, and in particular to a kind of operation tridimensional orienting headstock.

Background technology

Existing localization method includes mainly manually puncturing, utilizing the framed frame stereotactic apparatus of tradition, Use of Neuronavigation or operation The methods of robot, wherein：

The advantages of unarmed piercing method is fast and easy, but is operated because relying primarily on personal experience, the disadvantage is that smart True property is poor, fault rate is high, is not easy to be grasped and promoted, and especially has the case where surgical experience neurosurgeon all the year round in shortage Under, surgical effect is seriously affected, or even increase operation risk.

Horsley and Clarke in 1908 starts three-dimensional Bratn Stereotactic, and Spiegel in 1945 and Wycis are completed First time human brain stereotactic surgery since the dawn of human civilization, brain stereotactic is studied history above, and breakthrough is to be happened at 1979 for the second time, Brown utility models are registrated with positioning framework together with CT scan, are used for nervous system non-functional disease.China is 1993 The high-precision brain stereotactic that year can be connect by the First of Shenzhen Anke Hi-Tech Co., Ltd's production with CT or MR Instrument puts into Clinical practice, has greatly pushed the application and popularization of clinical horseley-Clarke technique at home.External good direction finder has： Leksell orientation systems, BRW/CRW orientation systems, Todd-well orientation systems etc.；The country has Shenzhen peace section high-tech limited The ASA-601 of company, 602 direction finders etc..These framves are widely used in clinic, and great advantage is that positioning accuracy is (1 millimeter high Rank).But its disadvantage is also clearly：It needs that basic ring is first installed, then carries out CT or MRI scan, then also to there is the soft of profession Part calculates target coordinate, and positioning preparation needs take a significant amount of time, and operating process is extremely complex, is not easy to be grasped, and Equipment is expensive, and all at 200,000 yuan or more, million yuan of needs of import or more are limited in vast base the domestic price of complete equipment Hospital promotes the use of.

Neuronavigation system, also referred to as frameless (Fameless) brain stereotactic or image are led as neurosurgery (Image-Guided Neurosurgery).Robert in 1986 and its colleague introduce one kind and are combined with CT images, microscope Frameless directional operation system, this brand-new idea one occurs, and evokes the heat for manufacturing and designing frameless directional operation rapidly There are a series of frameless directional operation systems in the case where engineering science and technology circle and manufacturer combine in tide.It is broadly divided into two classes：Joint Arm system (1987 by Watanabe utility models) and digitizer system.It is mainly digitizer system currently on the market, Point or less three kinds：1) sound wave digitizer：Roberts in 1986 report for the first time using sound wave digitizer tracking surgical instrument or Microscopical method, to start Frameless stereotactic neurosurgery.2) infrared digital instrument：Infrared digital instrument Navigation is the U.S. was applied to clinic in 1992, that is first optical operation navigation system in the world.It is most of currently on the market Product is optical operation navigation system, and China is to be introduced the optical operation navigation system in the U.S. by Shanghai Huashan Hospital for 1997 The country, the First operation guiding system that China voluntarily produces are to be produced by Shenzhen Anke Hi-Tech Co., Ltd for 1999 ASA-610T operation guiding systems and optical operation navigation system.3) electromagnetic digital instrument：Kato reports electricity within 1991 The design principle of magnetic digital instrument and clinical application, the system is mainly by 3 D electromagnetic digitizer, three-dimensional magnetic source, magnetic field induction Device and computer workstation are constituted.Although Use of Neuronavigation eliminates frame and keeps positioning operation more flexible, but equipment is more high It is expensive, and operation is same complicated time-consuming, and clinic is difficult to popularize.

The operating robot for being exclusively used in the positioning of brain section at present is the ROSA of French Medtech SA companies exploitation, and advantage is essence Really, intelligence, but price is too high, and the whole world also only equips tens at present, and domestic 4 hospitals only trivial at present introduce.

In conclusion the defect of above method is all obvious, and it is mainly expensive, it is complicated for operation.Reason is mainly Because Cerebral surgery positioning is an extremely complex problem, required in reliability and accuracy very high, general technology is set It is standby to be difficult to meet needs.In order to reach corresponding accuracy, with regard to product that is extremely complex, therefore developed on hardware configuration Cost is just very high, simultaneously as the reason of design principle, uses and is also very inconvenient.

Utility model content

To achieve the above object, the technical solution that the utility model is taken is：

Operation tridimensional orienting headstock, including semi-circular with a scale orientation bow and sliding block, semi-circular orientation bow bipod connect It is connected to skull fixing glue pedestal, sliding block and semi-circular orientation bow are sliding, and sliding block is equipped with the locking bolt for being fixed, The half opening guider insertion groove of a placement separate type guider, and the axle center pair of guider insertion groove are offered on the sliding block The center of circle of quasi- semi-circular orientation bow；For the scale using the axle center of side skull fixing glue as starting point, semi-circular orientation bow is divided into 180 Degree, each scale indicate 1 degree.

Wherein, a diameter of 240mm-300mm of the semi-circular orientation bow.

Wherein, the width of the semi-circular orientation bow is 20mm-50mm, and material can be metal, plastics and macromolecule material Material etc..

Wherein, bipod of the two skull fixing glue pedestals respectively by bolt and semi-circular orientation bow is affixed.

Wherein, the separate type guider use a variety of internal diameters separate type guider, such as Fr10, Fr12, Fr14, Fr16、Fr18；Puncture tube for guiding different model, limitation puncture direction, and separation design is convenient for taking-up puncture tube.

Wherein, further include an anti-penetration skull fixing glue, be fixed on skull, tip length be no more than skull thickness and Design restricted depth shelves.

The utility model has the advantages that：

1. using new stereotaxis principle, completely new three-dimensional coordinate system is devised using the characteristics of CT and MR, is avoided Conventional stereo direction finder needs installation positioning basic ring in advance and carries out CT and MR scannings again, avoids Use of Neuronavigation and needs in advance Scalp Marker is first pasted, operating robot is also avoided and needs to obtain CT and MR scan datas, simplify preoperative preparation Work, substantially reduces operation time.

2. the target coordinate in practical operation measures and position line labeling method is simple, it is easily mastered, only spends briefly Time can make accurate positioning.

3. frame is simple in structure, reuse or first use are may be designed as, it is of low cost, convenient for being pushed away in basic hospital Extensively, surgical effect is improved, medical expense is reduced.
