Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings specific embodiment of the utility model is described in detail.
Refer to shown in Fig. 1 to Fig. 5, patient-specific acetabular guide plate 100 of the present utility model is mounted on patient's basin bone 300, for guiding surgeon's handheld tool to punch on basin bone 300, and then acetabular cup (not shown) is guided and positions to acetabular bone pre-position.Described patient-specific acetabular guide plate 100 is that the basin bone threedimensional model that the medical image Reverse reconstruction according to patient's basin bone 300 generates designs and use rapid shaping technique to be made into integration.This patient-specific acetabular guide plate 100 includes hemispheric cup 1, cup 1 fixed arm 2 extending laterally setting, protruded out by cup 1 and multiple abutting feet 3 of interruption-like setting and by the guide part 4 upwardly extending setting in the middle part of cup 1.
Described cup 1 has the bottom 10 of rounded tabular setting and encloses the wall portion 11 being located at around bottom 10.Described wall portion 11 upwardly extends setting along bottom 10 circumferential direction.Described wall portion 11 is located in arc-shaped on bottom 10, and it has the inner surface 110 that is oppositely arranged and outer surface 111 and is connected outer inner surface 110 and the end face 112 of outer surface 111.Described cup 1 also has to be enclosed with wall portion 11 by bottom 10 and sets the dented space 12 formed.Described fixed arm 2 is to be extended laterally setting by the wall portion 11 of cup 1, can coordinate with the Periacetabular position 302 of basin bone 300, to be fixed on acetabular bone 301 position set in advance by patient-specific acetabular guide plate 100.Described abutting foot 3 is to be arranged by outer surface 111 outward in the wall portion 11 of cup 1, can abut with the corresponding site of the acetabular fossa 303 of acetabular bone 302, so that patient-specific acetabular guide plate 100 to position desired position to the preoperative planning process of acetabular bone 302.Described abutting foot 3 is that the outer surface 111 by the wall portion 11 of cup 1 protrudes out setting along away from dented space 12 direction, and it has the bearing surface 30 that the surface with acetabular fossa 303 corresponding site contacts.The surface of acetabular fossa 303 corresponding site that described bearing surface 30 coordinates with it is that mirror image is arranged.Abutting foot 3 in the present embodiment is three, and it is that circumferentially direction is spaced apart on the outer surface 111 in the wall portion 11 of cup 1.
Described fixed arm 2 includes by arm 20 horizontally extending after wall portion 11 top bending of cup 1 and the contact site 21 of being located at arm 20 end.Described arm 20 bends extended after being upwardly extended by the top of cup 1, it extends beyond acetabular bone edge 304 and extends at Periacetabular 302 corresponding site.Described contact site 21 has the binding face 210 that the surface with Periacetabular position 302 corresponding site contacts.The surface at described binding face 210 Periacetabular in contact position 302 is that mirror image is arranged.Described contact site 21 is arranged in offset shape with arm 20.Also there is on described fixed arm 2 fixing hole 22 running through setting along longitudinal and inclination.Described fixing hole 22 is located on contact site 21, is available for Kirschner wire (not shown) through to enter Periacetabular 302 corresponding site and then to be fixed on basin bone 300 by patient-specific acetabular guide plate 100.Described fixed arm 2 also has the protuberance 23 being located at arm 20 opposite sides, can patient-specific acetabular guide plate 100 place with on acetabular bone 301 after for doctor's fingerhold to finely tune the position of the relative acetabular bone of patient-specific acetabular guide plate 100 301, and then make patient spy's specific acetabular guide plate 100 position to acetabular bone 301 pre-position.Described protuberance 23 has the rubbing surface 230 contacted with doctor's finger.
Described guide part 4 is the most extended by the bottom 10 of cup 1.Described guide part 4 is located on cup 1 and is positioned at dented space 12.Described guide part 4 has substantially lead 40 in step-like setting and runs through the pilot hole 41 of setting along lead 40 axial direction.The central axes of acetabular cup (not shown) after acetabular cup (not shown) implants acetabular bone 300 in the bearing of trend place axis of described pilot hole 41 and preoperative planning.Described pilot hole 41 runs through, along longitudinally, the bottom 10 that lead 40 arranges and runs through cup 4.The bearing of trend place axis of described pilot hole 41 and the central axes of the acetabular fossa 303 of acetabular bone 301.Described pilot hole 41 bearing of trend place axis is arranged with the fixing hole 22 bearing of trend place inclined shape of axis.Described guide part 4 also has the multiple grooves 42 being located in lead 40 circumferential direction.Described groove 42 and pilot hole 41 are arranged in connected state, are used for processing heat radiation, prevent pilot hole 41 from deforming because temperature is too high man-hour adding.Described pilot hole 41 is screwed hole.
Described patient-specific acetabular guide plate 100 also includes the mark part 5 being protruded out setting by the top of cup 1.Described mark part 5 is upwards protruded out setting by the wall portion 11 of cup 1, can be fixed on basin bone 300 subsequently point to acetabular notch 304 at patient-specific acetabular guide plate 100, for playing the guiding role when being positioned to basin bone 300 by patient-specific acetabular guide plate 100, it is substantially shorter the corrective surgery time.Described mark part 5 is substantially located on cup 1 in arrow shaped.
Patient-specific acetabular guide plate of the present utility model 100 abuts with acetabular fossa 303 corresponding site and the contact site 21 of fixed arm 2 abuts to be located to acetabular bone 301 with Periacetabular 302 corresponding site by being protruded out the foot 3 that abuts of setting by the wall portion 11 of cup 1, and entered in Periacetabular 302 corresponding site to secure it on acetabular bone 301 through the fixing hole 22 of fixed arm 2 by Kirschner wire (not shown), thus realize the purpose on patient-specific acetabular guide plate 100 positioning and guiding to acetabular bone 301, simple in construction, easy to operate.And this utility model contacts and the surface laminating of the binding face 210 of fixed arm 2 and Periacetabular 302 corresponding site with the surface of acetabular fossa 303 corresponding site by abutting the bearing surface 30 of foot 3, the mode using locally laminating realizes the location of patient-specific acetabular guide plate 100 and acetabular bone 301, the problem that can avoid causing patient-specific acetabular guide plate 100 location to be forbidden when using full laminating type to contact with acetabular bone 301 because of the bony spur on acetabular fossa 303 at patient-specific acetabular guide plate 100.
To sum up, these are only preferred embodiment of the present utility model, scope of the present utility model should not limited with this, the most every simple equivalence change made according to claims of the present utility model and this utility model description with modify, all should still belong in the range of this utility model patent contains.
