Abstract
The utility model discloses a reduction of fracture director, the director includes flexion (2), flexion (2) one end links to each other with handle (1), the other end setting of flexion (2) reset mounting (3), restore to the throne mounting (3) inside for cavity (4), and link to each other the opening of the looks remote site of end with flexion (2) along for the cusp, set up hole (5) or open slot (6) of symmetry on the wall of cavity (4). The utility model discloses a director can be fixed the fracture piece after fracture piece resets immediately, the removal of the back fracture piece that prevents the to reset failure that leads to reseing.
Description
Technical field
This utility model belongs to technical field of medical instruments, and particularly, this utility model relates to a kind of reduction of the fracture guider.
Background technology
Fracture is that the seriality of bone structure ruptures wholly or in part.The main cause that fracture occurs mainly contains three kinds of situations: 1) direct violence: violence directly acts on a certain position of skeleton and causes this position fracture, often accompanies soft tissue injury in various degree.As wheel clashes into shank, there is fracture of shafts of tibia and fibula in shock place.2) indirect violence: by longitudinally conduction, leverage or twisting action make to fracture at a distance during indirect violence effect, as fall from eminence foot land time, trunk because gravity relation is sharply to pre-buckling, the vertebral body generation compressibility of breast lumbar spine intersection or bursting fracture.3) accumulation property strain: for a long time, repeatedly, slight direct or indirect damage can cause limbs a certain specific part fracture, also known as fatigue fracture, easily causes 1/3 shaft fracture under second and third metatarsal and fibula as walked at a distance.
The treatment of fracture generally adopts replacement and fixation, and after the reduction of the fracture, but after fracture site resets sometimes, sclerite often slides due to various factors, causes and resets unsuccessfully, therefore, needs after the reset to be fixed the sclerite after reset in time.
Therefore, a kind of reduction of the fracture guider that can overcome above-mentioned shortcoming of research design is needed badly.
Utility model content
The purpose of this utility model is, provides a kind of reduction of the fracture guider, and this guider can be fixed sclerite immediately after sclerite resets, and prevents the movement of sclerite after resetting from causing resetting unsuccessfully.
For achieving the above object, this utility model have employed following technical scheme:
A kind of reduction of the fracture guider, described guider comprises bending section 2, and described bending section 2 one end is connected with handle 1, and the other end of described bending section 2 arranges replacement and fixation part 3, described replacement and fixation part 3 inside is cavity 4, and the opening of the opposite end of holding that is connected with bending section 2 is along being dentation; The wall of described cavity 4 is arranged symmetrical hole 5 or open slot 6.
In this utility model, the opening of cavity edge is designed to dentation, is convenient to catch on fracture portions and resets.
Preferably, the hole 5 of described symmetry or the line of open slot 6 are through the center of cavity 4.The hole of above-mentioned symmetry or open slot are used for sutural penetrating, and after sclerite resets, adopt other utensils through fracture portions, the stitching thread crossed in the cavities are drawn past fracture portions, thus fracture portions are fixed.
Preferably, described replacement and fixation part 3 is bowl-type or truncated cone-shaped.Those skilled in the art can also select other shapes as required.
Preferably, described guider also comprises the sleeved mount 7 being arranged at handle 1 and bending section 2 junction, on described sleeved mount 7, activity arranges sleeve 8, the axial line of described sleeve 8 or through hole is set with axis parallel place, crochet hook 9 is placed in through hole, when described crochet hook 9 inserts, the tip of crochet hook 9 is positioned at cavity 4.
Preferably, described crochet hook 9 tip arranges agnail 10.
Preferably, described crochet hook 9 is positioned on the centrage of cavity 4.
In this utility model, the making material of reduction of the fracture guider can select rustless steel.What those skilled in the art can also select other to be applicable to as required prepares material.
The reduction of the fracture at the positions such as this utility model is applicable between tuberosity, elbow joint coronoid process, rear ankle.
Concrete using method of the present utility model is: for intertrochanteric fracture, open minimally invasive hole, fracture site is extend into from the side of bone by penetrating sutural reset guide device in symmetrical holes or open slot, adopt replacement and fixation part to harrow sclerite, resetted, keep motionless, punch until cavity from the side of fracture site, from this hole, stitching thread is pulled out, thus sclerite is fixed, prevent its slip from causing and reset unsuccessfully.
This utility model is compared to prior art, its advantage is: bowl-shape cavity is arranged in one end of guider by this utility model, this cavity is convenient to probeing into of crochet hook or other instruments of pulling strings, prevent the instrument of pulling strings from cannot lead stitching thread through after bone, and the inside cambered surface of cavity is when the instrument of pulling strings departs from cavity center, still by tool slide of pulling strings to cavity center, thus override interrupt can be avoided, larger wound is caused to fracture portions.

Detailed description of the invention
With the drawings and specific embodiments, this utility model is described in further detail below.
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of reduction of the fracture guider, described guider comprises bending section 2, described bending section 2 one end is connected with handle 1, the other end of described bending section 2 arranges the replacement and fixation part 3 of bowl-type, described replacement and fixation part 3 inside is cavity 4, and the opening of the opposite end of holding that is connected with bending section 2 is along being dentation; The wall of described cavity 4 is arranged symmetrical hole 5 or open slot 6.
The hole 5 of described symmetry or the line of open slot 6 are through the center of cavity 4.
As shown in Figure 1 and Figure 4, described guider also comprises the sleeved mount 7 being arranged at handle 1 and bending section 2 junction, on described sleeved mount 7, activity arranges sleeve 8, the axial line of described sleeve 8 or through hole is set with axis parallel place, crochet hook 9 is placed in through hole, when described crochet hook 9 inserts, the tip of crochet hook 9 is positioned at cavity 4.Described crochet hook 9 tip arranges agnail 10.Described crochet hook 9 is positioned on the centrage of cavity 4.
In the present embodiment, reduction of the fracture guider adopts rustless steel to make.
Concrete using method of the present utility model is: for intertrochanteric fracture, open minimally invasive hole, fracture site is extend into from the side of bone by penetrating sutural reset guide device in symmetrical holes or open slot, adopt replacement and fixation part to harrow sclerite, resetted, keep motionless, punch until cavity from the side of fracture site, from this hole, stitching thread is pulled out, thus sclerite is fixed, prevent its slip from causing and reset unsuccessfully.
