Description
Technical field
This utility model relates to a kind of surgical guide, and particularly a kind of 3D prints foramen intervertebrale lens targeting puncture percutaneous surgical guide.
Background technology
3D is printed on being applied in of medical domain and progressively spreads out and go deep into, and be the product highly customized to copying of human body position, printed by 3D, these parts can agree with completely with health, combine together with health.
Farthest can keep the integrity of fibrous ring as foramen intervertebrale lens vertebral column minimally invasive technology and keep the stability of spinal column, minimum to patient trauma in similar operation, effect is best.Current international field of spinal surgery has generally acknowledged that foramen intervertebrale lens Nucleus resection is developing into the leading modus operandi in this field in the future.
This technology can be divided into three parts: 1, targeting puncture technique, 2, reaming, tube indwelling technology, 3, operating technology under mirror.Wherein targeting puncture technique is the most key, and whether it directly determines successful surgery.
Current foramen intervertebrale lens targeting puncture technique (for waist 4/5 intervertebral disk hernia): according to the check result of preoperative CT, MRI of patient, find the outstanding target spot position of pressuring nerve, set puncture path by the personal experience of operator.Waist 4/5 gap and intervertebral foramina position is determined under the perspective of position, C arm machine positive side in operation process, and mark waist 4/5 Interstitial Water horizontal line with oil pen, the hand-held Kirschner wire of patient, repeatedly had an X-rayed by position, C arm machine positive side and determine that needle point arrives the puncture path at intervertebral disk hernia target spot position, rule along Kirschner wire with oil pen simultaneously, be with above-mentioned horizontal line point of interface percutaneous puncture point of performing the operation.Get percutaneous needle to thrust from point of puncture, inserting needle limit, limit perspective is until needle point arrives at target spot position namely complete puncture.The method can not avoid injured nerve in art, blood vessel, more cannot realize a step and precisely put in place.
Therefore, research and development one can arrive target spot position accurately, shortens the puncture time, reduces perspective radiation, and the foramen intervertebrale lens targeting puncture aid material of minimizing patients' neural, blood vessel injury probability is imperative.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of arrival target spot position that can be precisely safe, shortens the puncture time, reduces perspective radiation, reduces the 3D printing foramen intervertebrale lens targeting puncture percutaneous surgical guide of patients' neural, blood vessel injury probability.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of 3D prints foramen intervertebrale lens targeting puncture percutaneous surgical guide, and its innovative point is: comprise pedestal and guide plate body, and this guide plate body is by base supports and be positioned on human body; Described pedestal assumes diamond in shape, and its cornerwise point of intersection has a vertically disposed locating dowel, and its four angular vertexs place and locating dowel lower surface have one respectively for being connected with medical sheet of pasting the connecting hole realizing pedestal and fix; Described guide plate body is strip, and by for being connected the positioning section of locating with pedestal and forming for the puncture guide section entirety of Needle localization, the center of described positioning section has a locating hole stretched into for base stand location post; The front end of described puncture guide section has a guide pipe be obliquely installed, and is formed centrally one for the guide channel of biopsy needle guide in this guide pipe.
Preferably, the locating dowel top of described pedestal is provided with locking screw thread section, and bottom is provided with the positioning convex that at least one stretches out locating dowel surface; The locating hole of described guide plate is provided with along the axial extension of locating hole and locating slot that just can be chimeric with positioning convex.
Preferably, described guide plate positioning section top is an arcuate structure being convenient to grip.
Preferably, a reinforcement is also provided with between described arcuate structure and puncture guide section.
Preferably, the structure of lower surface for just fitting with body surface molded line in penetrating area needed for individuality of described guide plate puncture guide section.
The utility model has the advantage of:
(1) a kind of 3D of the present utility model prints foramen intervertebrale lens targeting puncture percutaneous surgical guide, comprise pedestal and the guide plate body of 3D printing shaping, this guide plate body is by base supports and be positioned on human body, is convenient to better resting guide between guide plate and pedestal by thread connection; Guide plate is arranged the stability that reinforcement can increase guide plate; Guide plate sets the gripping that arcuate structure is convenient to medical worker.
(2) 3D prints percutaneous surgery guide plate and drafts puncture path by preoperative, measure paracentesis depth, avoid injured nerve in art, blood vessel, puncture along guide hole in art, one step precisely puts in place, obviously can shorten operating time, reduces perspective amount of radiation, and for reaming below, put operation under pipe, mirror prerequisite be provided, reduce patients' neural, blood vessel injury probability simultaneously.
