Moving handle 2
Shown in Fig. 1, Figure 1A, Figure 1B, Fig. 1 D, Fig. 3, moving handle 2 is provided with the second finger ring 12A, third connecting rod 22, cam pair 23, and third connecting rod 22 is arranged between the second finger ring 12A and cam pair 23.
The center of the second finger ring 12A is E through hole 21A, and described E through hole 21A is used for finger (being generally middle finger traditionally) and passes.
Cam pair 23 is provided with convex cylindrical 23A, stopper slot 23C, A packing cavity 23D, B packing cavity 23E, draw-in groove 23F; The center of described convex cylindrical 23A is screwed hole 23B, and this convex cylindrical 23A is arranged in the B through hole 13A of fixed handle 1, and screwed hole 23B, for placing screw 3, can connect a nut through screw 3 end after screwed hole 23B; Described stopper slot 23C is for placing the limited block 13B of fixed handle 1; Described draw-in groove 23F is for placing the snap fit 71 in stretch 7.
Be placed with antifriction material in A packing cavity 23D and B packing cavity 23E, antifriction material can be match Hibisci Mutabilis.Rotating part between moving handle 2 and fixed handle 1 places antifriction material, is the friction in order to cause when reducing to move between the two.
In the present invention, moving handle 2 rotates around convex cylindrical 23A relative to fixed handle 1.
Door frame bar 4
Shown in Fig. 1, Figure 1A, Figure 1B, Fig. 1 D, Fig. 4, Fig. 4 A, the body of rod of door frame bar 4 is provided with axial U-lag 41, and this axial U-lag 41 is for placing stretch 7, and stretch 7 is mobile in axial U-lag 41; The bottom relative with described axial U-lag 41 is provided with top wire hole 42, this top wire hole 42 is for placing jackscrew 4A, one end of jackscrew 4A is placed in top wire hole 42 through the D through hole 14B on fixed handle 1, realizes the connection between door frame bar 4 and fixed handle 1 by jackscrew 4A.The other end end of door frame bar 4 is provided with longitudinal U-lag 43, and the side plate of longitudinal U-lag 43 is provided with G through hole 44, and another side plate of longitudinal U-lag 43 is provided with H through hole 45, and described G through hole 44 and described H through hole 45 pass for pin 6.Longitudinal U-lag 43 is for placing the connection handle 53 of dip stick 5.In the present invention, described pin 6 through after G through hole 44, K through hole 52 (being arranged on the connection handle 53 of dip stick 5) and H through hole 45, realizes the other end end connection handle 53 of dip stick 5 being movably arranged on door frame bar 4 in turn.
The diameter of the door frame bar 4 of the present invention's design is not easily more than 8mm, this is because the otch in joint is very little, the door frame bar 4 of oversized dimensions can not be used for carrying out Wicresoft's operation on joint.
In the present invention, the axial U-lag 41 of design is not slotted in the axial centre of door frame bar 4, this is because dip stick 5 will be arranged on the longitudinal center line of door frame bar 4, so the fluting of longitudinal U-lag 43 is on the longitudinal center line of door frame bar 4.
Stretch 7
Shown in Fig. 1, Figure 1A, Figure 1B, Fig. 1 D, Fig. 5, one end of stretch 7 is provided with snap fit 71, and the other end of stretch 7 is provided with bearing pin 72.Described snap fit 71 is placed in the draw-in groove 23F of moving handle 2; Described bearing pin 72 is placed in the J through hole 51 of dip stick 5.Bearing pin 72 and J through hole 51 are movable installation.
In the present invention, stretch 7 is the measurements realizing IA physical dimension (as length) for pull-up dip stick 5.
Dip stick 5
Shown in Fig. 1, Figure 1A, Figure 1B, Fig. 1 D, Fig. 6, one end of dip stick 5 is two-sided tolerance body 54, the opposite face of two-sided tolerance body 54 is carved with scale size, scale unit is 1 millimeter or 0.5 millimeter, and the cross section of described two-sided tolerance body 54 can be triangle 55, hexagon (six rib chis as shown in Figure 6A), rectangle (flat chi as shown in Figure 6B), circular (cylinder chi as shown in Figure 6 C); The other end of dip stick 5 is connection handles 53, and described connection handle 53 is provided with J through hole 51 and K through hole 52, and described J through hole 51 is for placing the cylindrical pin 72 of stretch 7, and described K through hole 52 passes for pin 6.
In the present invention, devise the dip stick 5 of different configuration (Fig. 6, Fig. 6 A, Fig. 6 B, Fig. 6 C), but connection handle 53 structure of design is identical, is convenient for changing dip stick 5 when this is conducive to the intraarticular structure measurement for different parts.Therefore, the connection of dip stick 5 and door frame bar 4 and stretch 7 one end is then adopt pin 6 and bearing pin 72.Preferred measuring junction is three-square rule, and prismatoidal measuring junction ensures convenient reading, and laminating is reliable.
In the present invention, the scale unit on the two-sided tolerance body 54 on dip stick 5 is 1 millimeter or 0.5 millimeter.Because the intraarticular narrow space in Minimally Invasive Surgery, dip stick 5 needs to rotate the tested position of rear laminating, therefore dip stick 5 can not design excessive, not so can not enter in surgical environments.
In the present invention, dip stick 5 is designed to opposite face (two-sided) to be had and measures prompting size, to facilitate some medical worker for left-handed operation or right-hand operated, and the left hander namely said in common saying or right-handed person.
Dip stick and operation clamper combine by the present invention, by the opening and closing movement of fixed handle and moving handle, stretch is driven to move in the axial U-type groove of door frame bar, and then drive dip stick to rotate at intra articular, to ensure that measuring junction can fit to tested tissue, realize the accurate measurement of various anatomic parameter, contribute to the impairment factor passing judgment on anterior cruciate ligament clinically, and can provide a large amount of the most direct for ACL reconstruction operations under Wicresoft's arthroscope, reference index the most accurately, as green diameter and the length of ACL, the shape of the true stop of ligament and position, and then make anterior cruciate ligament Anatomical Reconstruction become possibility, greatly improve patient clinical curative effect.
The metering system of survey tool:
When using the medical measuring apparatus of the present invention's design to carry out the intraarticular structure measurement in Minimally Invasive Surgery, be connected on by thumbstall on the finger ring of fixed handle 1, middle finger is socketed on the finger ring of moving handle 2, motion is drawn close by middle sensing thumb, then moving handle 2 draws close fixed handle 1, stretch 7 is pulled up, dip stick 5 is holded up, and measures tested partial joint inner structure size with the dip stick 5 holded up.
After measurement completes, leave measurement environment, unclamp moving handle 2.
During the medical measuring apparatus not using the present invention to design, dip stick 5 and stretch 7 can be levels, also can be separated, detachable, as adopted bolt, buckle carries out Fast Installation.
