Detailed description of the invention
Be directed to the current problem not having specific purpose tool in nerve root canal probe procedure, inventor is from actual demand, in conjunction with human physiological structure's feature, and the actual demand in operations research process, have devised a kind of instrument in use with good result:
A kind of nerve root canal probe, this nerve root canal probe is the integral structure connected and composed successively by probe 1, linkage section 2 and handle 3, described probe 1 entirety is spindle-type α-Fe2O3, probe 1 comprises tip 11, central part 12 and basilar part 13, its sharp head 11 is blunt rounded, tip 11 integral diameter evenly increases, and is central part 12 in the end of tip 11, is also largest diameter place on whole probe 1; Start diameter from central part 12 to reduce gradually, form the basilar part 13 be connected with linkage section 2; Axially, the length of tip 11 is greater than the length of basilar part 13 to probe 1.
As shown in Figure 1, be overall structure schematic diagram of the present invention.Probe of the present invention, its basic structure forms primarily of three parts:
1. pop one's head in 1.
Probe 1 is a most important structure in this programme, and in operation, 1 entirety of popping one's head in is insinuated in nerve root canal and intervertebral foramina, determines that nerve root canal is the need of further decompression by 1 sense of touch returned of popping one's head in.Therefore pop one's head in 1 in the design process, need to consider many problems: the first, size issue.Probe 1 is whole probe part foremost, and it needs to be deep in narrow and small gap and operates.If so it is excessive, then not easily pass through the nerve root canal of stenosis, too small, sense of touch can not be fed back well.The second, shape problem.Pop one's head in 1 global design process, owing to which carry the dual function advanced and detect, therefore require that its global shape not only will be conducive to traveling process, also require that it can feel the space size in nerve root canal in all directions.3rd, angle problem.Accurately the direct of travel of control probe 1, to significant in whole probe procedure.As direction occurs that deviation is not only difficult to reach commitment positions, also nerve injury may be caused.But the whole probe procedure direct hand-held that is doctor, any trickle action all may cause deviating, and therefore just requires that the angle of probe 1 can match with linkage section 2, handle 3, forms a kind of being beneficial to and detects, is convenient to the structure that manipulates.
Thus, inventor considers above-mentioned factor, gives a kind of probe 1 structure.As shown in Figure 1 and Figure 2, the probe 1 that proposes in the present invention entirety is spindle-type α-Fe2O3, but considers the factor of volume size in use procedure, probe 1 asymmetrical spindle-type α-Fe2O3, that is spindle-type α-Fe2O3 one end point some and the other end is more blunt.Probe 1 is divided into three parts: Part I is tip 11, and tip 11 is positioned at whole apparatus foremost, and in actual use, 11, tip is insinuated in nerve root canal at first, and be in front end in follow-up operation always.For the ease of its probe procedure of advancing, tip 11 is designed to blunt round structure, and as shown in Figure 2, namely tip 11 can be regarded as gyroscope-like.Blunt round structural design, is not only convenient to it and is easy to when detecting root pipe enter, be convenient to traveling process, and due to its smooth surface, also can not injured nerve.The tip of tip 11 is to its end, and uniform diameter increases, and reaches largest diameter place on probe 1 at its end diameter, and this position is called central part 12.The second part of probe 1 is central part 12, and the size of central part 12 determines the suitability of probe 1, and by central part 12 energy effective Feedback sense of touch, assist physician judges.Central part 12 is the position of largest diameter on probe 1.Part III is basilar part 13, probe 1 from central part 12 diameter reach maximum after, its rear end need carry out shrinking to limit overall size, this part contraction process is not uniform, and the tip 11, the basilar part 13 that therefore cause probe 1 are asymmetric.A spindle-type α-Fe2O3 for symmetry in this way, then will increase the entire length of probe 1, is unfavorable for operation.The circumference entirety of probe 1 is smooth circular configuration, and in its axial direction, namely runs through on the centerline direction of probe 1, and the length of tip 11 is greater than the length of basilar part 13.Another function of basilar part 13 is connected with linkage section 2.
About the concrete technical parameter of each several part, be described below further:
As shown in Figure 2, Fig. 2 axially cuts off with it probe 1 part, cuts rear formed face.In probe 1 cross section vertically, the angle at tip 11 place is designated as α 1, and the angle of central part 12 is designated as α 2, then have: α 2 > α 1.The angle at tip 11 place described here, refers to angle as shown in Figure 2, after namely tip 11 cuts off, and what its tip presented is a circular angle.Because tip 11 evenly increases, therefore angle α 1 be here exactly tip 11 cut off rear formation two limit extended lines between angle.These number of degrees are advisable with about 60 °.Central part 12 is the angle α 2 of the end of tip 11, central part 12 here, refers to the angle between tangent line and basilar part 13 and tip 11 end junction tangent line cutting off rear tip 11 end.To outward seeming, tip 11 and basilar part 13 should seamlessly transit here, and namely central part 12 outer surface is round and smooth shape.The size of α 2 is advisable with about 120 °.
About basilar part 13, also there is its strict designing requirement:
In probe 1 cross section vertically, the edge contour of basilar part 13 is by two sections of symmetries and form with the bottom surface circular arc being connected two sections of side circular arcs with the side circular arc that central part 12 connects, and bottom surface circular arc is connected with linkage section 2; Wherein the curvature of side circular arc is greater than the curvature of bottom surface circular arc.
As shown in Figure 2, in the face of cutting off, basilar part 13 is not one section of overall circular arc, but be spliced by three sections of circular arcs.In these three sections of circular arcs, have two sections be pop one's head in 1 axial line symmetrically arranged each other, curvature, size are all identical, and these two sections of circular arcs are called side circular arc, and side circular arc connects with central part 12; Another section of circular arc is bottom surface circular arc, and it connects two sections of side circular arcs, makes the profile whole-body of basilar part 13 be about semicircle.But be not a same curvature transition between bottom surface circular arc and side circular arc, the curvature of bottom surface circular arc is less than side circular arc, and namely relative to side circular arc, bottom surface circular arc is more level and smooth, and degree of crook is smaller.Basilar part 13 structure is set, to fix with linkage section 2 on the one hand, that basilar part 13 this set and tip 11 place constitute unique spindle-type α-Fe2O3 on the other hand, in the process of detecting complete rollback, and when needing movable in probe procedure, due to the level and smooth setting at circular arc place, basilar part 13 side, root pipe is more easily strutted to both sides smoothly, is conducive to the activity of probe 1.
At probe 1 axially, its entire length L1 is 4 ~ 8mm, is wherein the best with 6mm; The tip 11 director degree L2 of probe 1 is about 4mm, and basilar part 13 length L3 is about 2mm.On the direction perpendicular to probe 1 axis, namely pop one's head in the radial direction of 1, the maximum gauge of probe 1, namely central part 12 place diameter D1 is about 5mm, this diameter is less than normal neuronal root pipe interior diameter, detecting is touch surrounding situation in nerve root canal by the enlarged area of this central part 12, and judges effect of easing stress by pop one's head in 1 mobility in nerve root canal and surrounding space.If D1 is too small, then probe 1 is easy to enter nerve root canal, less to the damage risk of surrounding tissue, but the meticulous space can not truly felt around in nerve root canal of probe 1, easily bring misleading to patient, cause pressure relief ranges too small, decompression not thorough or invalid.If D1 is excessive, then probe 1 is difficult to enter nerve root canal, can not effectively detect space in nerve root canal, may cause damage if make a forcible entry into nerve root, may cause excessive decompression in art, adds local bone destruction and operation risk.Circular arc chord length D2 diametrically in bottom surface is about 3mm.
2. linkage section 2.
Linkage section is L shape structure, is made up of forearm and postbrachium, and forearm is thin and postbrachium is thick, and the length L4 of forearm is about 15 ~ 25mm, take 20mm as the best; The diameter D3 of forearm is about 3mm, and the length L5 of postbrachium is 25 ~ 35mm, take 30mm as the best; The diameter D4 of postbrachium is about 4mm.Forearm and postbrachium form L shape structure jointly, but consider the physiological structure of operating process reality and be beneficial to the factor of doctor's operation, angle α 3 between forearm and postbrachium is advisable with about 120 °, this angle is through repeatedly to test finally to be determined, angle too small then detects the risk easily increasing forearm extruding or injured nerve root in the process of nerve root canal, and angle is excessive, detects in the process of nerve root canal and easily increases postbrachium extruding or damage spinal dural risk; When probe is positioned at root pipe, postbrachium is positioned at the top of canalis spinalis (spinal dura mater) obliquely, decreases postbrachium extruding or damages spinal dural risk, and when using the direction of handle adjustment probe, forearm and postbrachium can not extrude dura mater easily simultaneously.Similarly, when detecting offside nerve root canal, also can reduce forearm and postbrachium extrudes spinal dural risk.The forearm of linkage section is fixedly connected with the basilar part of probe, and the axial line of probe overlaps with the axial line of forearm, and namely probe is overall equidirectional with forearm, convenient manipulation.
The forearm L4 of linkage section is preferably set to about 20mm, with distance travelled close in nerve root canal of nerve root, therefore when using nerve root canal probe to detect, the length L4 of the forearm of linkage section is enough to ensure that probe can detect the whole process of nerve root canal, effectively can detect the effect of easing stress of nerve root canal inside.If the length L4 of forearm is too small, probe can only detect partial nerve root pipe, effectively cannot detect the far-end of nerve root canal, causes decompression not.If the length L4 of forearm is excessive, when hands intraoperative porbe enters nerve root canal, linkage section easily touches spinous process etc., makes troubles to operation, and probe to enter nerve root canal excessively dark, if before touching vertebral body, outside organ and tissue, add the risk of Accessory injury in art.
3. handle 3.
Handle 3 is cylindrical structural, and handle 3 reduces to the orient diameter of front end gradually from end; Be provided with anti-slip section on the handle 3.The entire length L6 of handle 3 is about 100mm, the diameter D5 of handle 3 end is about 8mm, this length and diameter are convenient to patient and are gripped, anti-slip section is the part that patient grips, coarse some planar design can increase contact surface and the strength that patient grips nerve root canal probe, be convenient to patient and control the direction of popping one's head in and the dynamics entering nerve root canal by gripping handle 3, reduce nerve root canal probe landing and Accessory injury risk in art.
Probe, linkage section and handle 3 are smoothly connected and in aggregates successively, and each several part smooth surface, be stainless steel.When operating in art, the front end of probe, linkage section and handle 3 touches the tissue in visual area unavoidably, especially nerve root, spinal dura mater, muscle vascular etc., nerve root probe each several part junction is smoothly connected and each several part smooth surface (anti-slip section except outdoor handle 3), can obviously reduce in art the Accessory injury operating and bring.
Use operation of the present invention as follows: after vertebrae plate resection, to appear exiting nerve root, hold with a hand the anti-slip section of nerve root canal probe handle 3, the forearm of probe and linkage section is moved towards in soft feeding intervertebral foramina and nerve root canal along nerve root, in the process deepened continuously, surrounding tissue in nerve root canal is touched gently with probe, feel the space size in it, probe is goed deep in nerve root canal further, until forearm all enters.After detecting end, along nerve root canal direction taking-up probe gently, namely complete probe operation.
