Abstract
The utility model relates to a minimally invasive surgical instrument for syndesmorrhaphy and belongs to the technical field of medical instruments, particularly a fixing instrument for repairing the ligament, curing the tendon damage and restoring the stability of joints. The minimally invasive surgical instrument comprises a guide pin (1), a hollow drill (2), a survey meter (3) and a miniature steel plate (4). The minimally invasive surgical instrument is characterized in that the guide pin (1) is in the form of a long and thin rod. One end of the guide pin is in the form of a rhombic, flat and pointed end, and the diameter of the end is larger than the diameter of the rod. The other end of the guide pin is provided with a needle eye, so that a suture wire can be conveniently threaded through the needle eye. The rod part of the survey meter (3) is provided with accurate scales, and the top end of the survey meter (3) is provided with a draw hook. The miniature steel plate (4) can be manufactured in different sizes so as to be suitable for suitable for different groups of people. By means of the minimally invasive surgical instrument, the guide pin can be accurately positioned and the trauma is small. Meanwhile, the minimally invasive surgical instrument is simple in operation and safe in fixation effect.
Description
Technical field
This utility model relates to a kind of Minimally Invasive Surgery apparatus for desmorrhaphy, belongs to technical field of medical instruments, is to repair ligament, tendon injury, rebuilds the stable fixed apparatus in joint.
Background technology
After ligament or tendon injury, have a strong impact on people's orthobiosis, to cut a large opening in order to remove ailing general way, with screw, U-shaped nail, the a series of implant product such as steel plate is fixed, like this time of surgery recovery longer, secondary wound face is larger, fixing more loaded down with trivial details, rear skin surface has larger cicatrix.
Summary of the invention
This utility model can be simplified operation technique mode, shortens operating time, reduces patient's misery, more adapts to doctor and promotes the use of.
The technical solution of the utility model is as follows:
This utility model is made up of guide pin (1), core drill (2), measuring device (3), miniature steel plate (4), it is characterized in that: guide pin (1) is elongate rod, head is the flat tip of rhombus, slightly larger in diameter is in the size of bar portion, afterbody is with connecting sutural pinprick, overall length is 400mm, and bar portion diameter is 2.2mm.The drilling rod that bores bone marrow is hollow design, being convenient to guide pin (1) passes through, according to the location of guide pin (1), hole more accurate, there is uniform scale in measuring device (3) measuring stick portion, head has a drag hook, and doctor accurately selects the size of miniature steel plate (4) according to the scale of measuring.There are two locating holes at miniature steel plate (4) middle part.Being convenient to stitching thread penetrates and locates.
There is scale mark accurately in the bar portion of measuring device (3), is convenient to doctor according to the rational regioselective product of Measurement scales.
Guide pin (1) is the endoporus through core drill, and hollow drill is through the endoporus of measuring device, and there are two fixing holes the centre of miniature steel plate (4).
This utility model compared with prior art has the following advantages:
1. simple to operate, convenient fixing.
2. secondary wound face is little, more after without cicatrix
The utlity model has simple in structure, easy to operate, its processing cost of handling ease is low, be suitable for medical industry and apply.
Accompanying drawing explanation
Fig. 1 is this utility model guide pin structural representation.
Fig. 2 is this utility model core drill schematic diagram.
Fig. 3 is this utility model measuring device schematic diagram.
Fig. 4 is this utility model miniature steel plate schematic diagram.
Fig. 5 is this utility model population structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is guide pin (1), and being about 400mm diameter 2.2mm head is the flat tip shape of rhombus, is slightly coarser than bar portion diameter, and bar afterbody has a threading pinprick.
Fig. 2 is that the diameter of its mesopore of core drill (2) matches with guide pin (1) external diameter, and the guiding by guide pin (1) while boring myelopore is located.
Fig. 3 is measuring device (3), has scale mark accurately on the measuring stick of measuring device, determines the size of miniature steel plate (4) according to the length of measuring.
Fig. 4 is miniature steel plate.Be of a size of 20 × 5 × 1.25, the You Liang hole, center of steel plate, aperture is 2mm, two pitch-rows are 5mm.
Operational approach is, selected boring after bony site, skin with guide pin (1) through skeleton and offside, selected core drill (2) is by position and the direction of the drill guide bone marrow of guide pin (1), bored the cortical bone of offside, measure the degree of depth in bone marrow tunnel with measuring device (3), graft two ends fasten stitching thread, stitching thread is through two apertures of miniature steel plate (4), pass again the pinprick of guide pin (1) afterbody, skin by offside outwards slowly pulls out guide pin (1), stitching thread, miniature steel plate (4), graft passes osseous tunnel by guide pin (1), in the time that miniature steel plate (4) passes offside cortex, one end static line of tractive graft in the other direction, now changing because of direction of draw, miniature steel plate (4) laterally slides, be stuck in the cortical bone surface of osseous tunnel outlet, thereby arrive fixing object.
Claims (1)
