Abstract
The utility model relates to a closed surgical instrument for fixing ligamenta with miniature steel plates, which comprises a slim threading guidance pin and a graduated probe, wherein, the top end of the threading guidance pin, which is slightly thicker in diameter than the pin body, is a prismatic tabular tip, and the tail end of the pin body has a traction pin eye; the graduated probe comprises a pin bar which has scale labels, and a pin handle whose top end is hooked. The utility model additionally comprises a ligamenta measurer, a hollow drill and a miniature fixing steel plate. The threading guidance pin not only guides the tunnel direction of drilling bones, and the miniature steel plates are pulled by traction wires to the part to be fixed. The closed surgical instrument, therefore, has the advantages of safe and reliable fixation, less pain to patients and simple operation.
Description
This utility model relates to a kind of closed miniature steel plate ligament fixation surgical instrument of repairing ligament, tendon injury operation usefulness.
Through osseous tunnel fixedly ligament, tendon or other graft materials, be to repair ligament injury, rebuild commonly used in the stabilization of joint, modus operandi reliably.Usually osseous tunnel offside export department need do otch again, and is fixing with screw, U sprig, spline nail, steel plate etc.This kind method operation technique is more loaded down with trivial details, and operating time is long, and patient's misery is many, skin leaves cicatrix.
The novel purpose of this practicality invention is a kind of closed miniature steel plate ligament fixation surgical instrument of design, simplifies operation technique.Shorten operating time, alleviate patient's misery.
This utility model comprises: the elongated guide pin of wearing, and the top is the flat tip of prismatic, and diameter slightly is coarser than needle body, and the needle body afterbody has the traction pinprick;
A calibrated probe: comprise shank and needle handle two parts, scale label is arranged on the shank, the top is hook-shaped;
This utility model also comprises ligament measuring device, core drill and miniature fixation steel plate;
The ligament measuring device is round barrel shape, and the external diameter of internal diameter and core drill is complementary; The internal diameter of core drill with wear the guide pin shank and be complementary.
There are two fixing holes at the center of miniature fixation steel plate.
The utility model has the advantages that: wear the not only direction of drill guide osseous tunnel of guide pin, and by draught line with the miniature steel plate tractive to fixed position, avoid performing an operation again otch, operation technique is easy, patient is painful few, fixing safety, reliably.
Introduce this utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of wearing guide pin,
11-shank wherein, the flat tip of 12-, 13-pinprick;
Fig. 2 is the calibrated probe structural representation,
21-shank wherein, the 22-needle handle;
Fig. 3 is the core drill sketch map;
Fig. 4 is the fixing sketch map of ligament;
Fig. 5 is miniature fixation steel plate structural representation,
50-fixation steel plate wherein, the 51-hole.
With reference to accompanying drawing, wear guide pin (10) for elongate is about 400mm, diameter 2.2mm, the flat tip of its vertical prismatic (12) is slightly thicker than shank (11), and the shank afterbody has a 10mm draught line pinprick (13).
Calibrated probe comprises shank and needle handle two parts.Scale label is arranged on the shank, and the top is hook-shaped.
The ligament measuring device is round barrel shape, and the external diameter of internal diameter and core drill is complementary.Core drill is selected for use general, its internal diameter with wear the guide pin shank and be complementary.
Miniature fixation steel plate: be of a size of 20 * 5 * 1.25mm, there are two holes at the steel plate center, and two hole centre-to-centre spacing are 5mm, and the aperture is 2mm.
During operation technique, after the selected brill bony site, pass skeleton with guide pin earlier, and pass offside skin, the position of drill guide osseous tunnel and direction then according to the model of measuring device, are selected corresponding core drill for use, overlap and wear guide pin brill osseous tunnel.After core drill drills through the offside cortical bone, measure the osseous tunnel degree of depth with the scale pin.The graft two ends are with bifilar cordonnet blanket suture, and knotting was fixing after suture passed miniature fixation steel plate two holes.The length of static line generally slightly is shorter than the degree of depth of osseous tunnel according to the operation needs.Other as draught line, passes miniature steel plate distally stomidium with a thick line, passes the pinprick of guide pin afterbody again.Slowly pulled out outward by offside skin and to wear guide pin, static line, miniature steel plate, graft pass osseous tunnel in proper order with wearing guide pin.When miniature steel plate passes offside cortex, the static line of reverse tractive graft end, change because of direction of draw this moment, and miniature steel plate laterally slides, and is stuck in the cortical bone surface of osseous tunnel outlet.
