Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, more particularly, refer to a kind of medical measuring apparatus of the measurement human synovial inner structure size for Minimally Invasive Surgery.
Background technology
Knee joint is human body maximum, the most complicated trochoid of structure constitute and function, by the synovial fluid in bone, articular cartilage, soft tissue (ligamentaum cruciatum, meniscus), articular cavity, be coated with and have the reinforcing of abarticular ligament and form with joint capsule.The incidence rate of knee joint injury is higher, occupies first of the each joint injury of human body, the most common with the damage of ligamentaum cruciatum, meniscus and articular cartilage clinically.Therefore, kneed dissection, image and clinical research more and more come into one's own in recent years, and various correlational studyes are also popular at present research fields.
Anterior cruciate ligament (ACL) is the most important forward direction rock-steady structure of knee joint, after damage, can produce obvious knee joint forward direction shakiness, have a strong impact on knee joint function, the primary structure such as secondary articular cartilage, meniscus infringement thereupon, causes the generation of articular degeneration and osteoarthritis.Clinical practice and experimental studies results show that, after ACL fracture, early stage reconstruction can recover kneed stability, prevents and delay the generation of osteoarthritis.At present, the treatment of knee joint ACL fracture focuses on that reasonable selection, the ligament of Minimally Invasive Surgery, graft under the method, mirror of ligament lapse to biology and postoperative reasonable early rehabilitation etc.Along with the continuous maturation of knee arthroscope technology and perfect, under arthroscope, Wicresoft rebuilds ACL operation has become in knee arthroscope surgery effectively Therapeutic Method.
The high risk factor of cross ligament damage comprises the extrinsic factor such as individual oneself factor and sports events, equipment, place and training strength such as abnormal, intercondylar fossa paramophia of age, sex, Body Mass Index, menstrual cycle, the lower limb line of force, arthrochalasis degree, muscle strength.Wherein, study hotspot in recent years about the research of intercondylar fossa, but, because intercondylar fossa form is irregular, the imaging examination results such as X-ray, CT and MRI are taken position to be affected greatly, and under arthroscope directly measurement lack instrument accurately, thereby, the research progress of intercondylar fossa always sluggishness not before.

In the present invention, moving handle 2 rotates around convex cylindrical 23A with respect 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 in the axially interior movement of 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 being connected 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, on the side plate of longitudinal U-lag 43, is provided with G through hole 44, on 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.Longitudinally 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, is realized the other end end that the connection handle of dip stick 5 53 is movably arranged on to door frame bar 4 in turn.
The diameter of the door frame bar 4 of the present invention's design is difficult for exceeding 8mm, and this is that the door frame bar 4 of oversized dimensions can not be used for carrying out Wicresoft's operation on joint because the otch in joint is very little.
In the present invention, the axial U-lag 41 of design is not at the axial centre fluting of door frame bar 4, and this is because dip stick 5 will be arranged on the longitudinal center line of door frame bar 4, so longitudinally the fluting of 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 is movable installation with J through hole 51.
In the present invention, stretch 7 is to realize the measurement to 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, on the opposite face of two-sided tolerance body 54, be 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, designed the dip stick 5 of different configurations (Fig. 6, Fig. 6 A, Fig. 6 B, Fig. 6 C), but connection handle 53 structures of design are identical, this is convenient for changing dip stick 5 while being conducive to for the intraarticular structure measurement of different parts.Therefore, dip stick 5 is connected with door frame bar 4 and stretch 7 one end, is to 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, the tested positions of laminating after dip stick 5 needs to rotate, therefore that dip stick 5 can not design is excessive, not so can not enter in surgical environments.
In the present invention, dip stick 5 is designed to opposite face (two-sided) and has the prompting of measuring size, to facilitate some medical worker as left-handed operation or right-hand operated, and the left hander of saying in common saying or right-handed person.
The present invention combines dip stick and operation clamper, by the opening and closing movement of fixed handle and moving handle, drive stretch to move in the axial U-shaped groove of door frame bar, and then drive dip stick in joint inner rotation, to ensure that measuring junction can fit to tested tissue, realize the accurate measurement of various anatomic parameters, contribute to pass judgment on clinically the impairment factor of anterior cruciate ligament, and can provide the most direct in a large number for ACL reconstruction operations under Wicresoft's arthroscope, reference index the most accurately, as the green diameter of ACL and length, 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 the medical measuring apparatus that uses the present invention to design carries out the intraarticular structure measurement in Minimally Invasive Surgery, be connected on the finger ring of fixed handle 1 by thumbstall, middle finger is socketed on the finger ring of moving handle 2, draw close motion by middle sensing thumb, moving handle 2 is drawn close fixed handle 1, stretch 7 is pulled up, dip stick 5 is holded up, and uses the dip stick 5 of holding up to measure tested part intraarticular physical dimension.
After measurement completes, leave measurement environment, unclamp moving handle 2.
While not using the medical measuring apparatus that the present invention designs, dip stick 5 can be level with stretch 7, can be also that separate, detachable, as adopted bolt, buckle to carry out Fast Installation.
