Description
Technical field
This utility model relates to a kind of medical instrument, especially a kind of skeleton for clamping fracture, and the extremity exterior fixation bracket that drill bit can be guided to carry out holing puts nail guider.
Background technology
The skeleton of fracture is holed, it is always a very difficult thing, because need to carry out active force to the skeleton of fracture to the drilling into bone of fracture, the skeleton of a pair fracture carries out active force, skeleton can be moved, even if fix skeleton by artificial mode, because skeleton is by the process of holing, constantly holed by shake, so precision is difficult to be protected, difficulty installed by steel plate, and the drilling into bone of fracture in the past, need two doctors, one resets the bone reduction of fracture, one utilizes the bony areas of drill bit to fracture to hole, so low to the drilling efficiency of skeleton, precision is low, cost of labor is high, and adopt a doctor to utilize the skeleton of clip reseting fracture, when a doctor utilizes the bony areas of drill bit to the good fracture of clamping to hole, need to the skin and flesh otch needs of patient cut larger, common clip could be extend in skin and flesh, so large for the wound area of patient, healing time is slow.
Utility model content
This utility model will solve the shortcoming of above-mentioned prior art, there is provided an a kind of doctor just can carry out clamping to the skeleton of fracture to reset, and the extremity exterior fixation bracket providing the skeleton of drill guide cover to fracture to carry out boring pilot bore hole puts nail guider, meet a doctor when the bony areas of the fracture to patient clamps, the guide sleeves that also can simultaneously provide boring to guide carries out the demand of precisely boring to patient.
This utility model solves the technical scheme that its technical problem adopts: this extremity exterior fixation bracket puts nail guider, comprise tong arm and lower tong arm, upper tong arm is fixed with the hinge axis one of middle its central band through hole, the hinge axis two of its central band through hole during lower tong arm is fixed with and mates with hinge axis one, the centre bore of hinge axis one and hinge axis two is provided with connecting hinge chain rivet one and hinge axis two and rivet with centre bore, the centre bore of rivet is provided with dwang, one end of dwang is fixed with guide sleeves, and the other end is fixed with the limited block being greater than rivets central hole;
The straight-bar two that upper tong arm comprises straight-bar one, is fixed on the curved portions one of straight-bar one front end face, is fixed on straight-bar one rear end face, the end of straight-bar two is fixed with to be arranged on holds ring one inside straight-bar two;
The straight-bar four that lower tong arm comprises straight-bar three, is fixed on the curved portions two of straight-bar three front end face, is fixed on straight-bar three rear end face, the end of straight-bar four is fixed with to be arranged on holds ring two inside straight-bar four;
Arrange in angle between straight-bar two and straight-bar four, clamp area is formed between curved portions one and curved portions two, straight-bar two is provided with the arc-shaped rack be slidably connected along straight-bar two length direction, straight-bar four has the arcuate socket with arc-shaped rack size location matches, the camber line side of arcuate socket being fixed with one group of arcuately hole uniform and with the limiting tooth of the tooth size shape location matches on arc-shaped rack, tooth tooth angle on arc-shaped rack down, the tooth tooth angle of limiting tooth, arc-shaped rack is fixed with the back-moving spring that arc-shaped rack can be made to reset upward.During use, the extremity exterior fixation bracket closing upper tong arm and lower tong arm is up and down put nail guider, reach in the wound of incision skin and flesh, then arc-shaped rack is stirred with hands, the tooth of arc-shaped rack and limiting tooth are thrown off, meanwhile finger struts tong arm and lower tong arm, and surround the skeleton of fracture, then arc-shaped rack is unclamped, utilize the reset force of back-moving spring, arc-shaped rack is resetted, simultaneously tong arm and lower tong arm in finger grips, clamp area is made slowly to clamp the skeleton of fracture, tooth simultaneously on arc-shaped rack to be fitted on limiting tooth and to send the sound of " click click ", and the angle constantly increased between straight-bar two and straight-bar four, so after the skeleton of the good fracture of clamping, hands can unclamp (its principle is: due to the angle between straight-bar two and straight-bar four reduce time, if manually do not stir arc-shaped rack, the tooth on arc-shaped rack is made to throw off limiting tooth, tooth on arc-shaped rack can limited tooth spacing, can not move), at this moment drill bit of can taking is holed by the bony areas of guide sleeves to fracture, one man operation can be realized, after the skeleton of fracturing is handled well by drill bit, only need manually to stir arc-shaped rack, arc-shaped rack and limiting tooth are thrown off, and manually make the angle between straight-bar two and straight-bar four reduce, just easily extremity exterior fixation bracket can be put nail guider to take out from human body.
Perfect further, curved portions one has the passage by curved portions two.Here curved portions one has passage and by the setting of curved portions two, when curved portions one and curved portions two can be made to close up, height up and down reduces, but the opening angle of clamp area remains unchanged, thus can utilize minimal incision * just can extremity exterior fixation bracket put nail guider extend in patient's skin and flesh, reduce otch, thus the speed of healing is faster.
Perfect further, the surface of upper tong arm and lower tong arm is all fixed with the reinforcement of outwardly convex.This set, can strengthen the intensity of upper tong arm and lower tong arm, and in guarantee, tong arm and lower tong arm can not deform when clamping the skeleton of fracture, thus can not affect clamping effect and firm grip degree.
Perfect further, hold ring one and hold ring two longitudinal direction and be staggeredly arranged.This set, when the angle that can ensure between straight-bar two and straight-bar four diminishes, can ensure to hold ring one and hold ring two and can not collide, and this set, the opening angle of clamp area can be increased, also can be suitable for at larger skeleton, highly versatile.
Perfect further, the number of degrees of angle a are 40 °.This set, can ensure best clamping feel, more convenient hands stirs arc-shaped rack.
The effect that this utility model is useful is: this utility model smart structural design, rationally, utilize the combination of arc-shaped rack and limiting tooth conveniently can clamp the skeleton of fracture, and extremity exterior fixation bracket can be unclamped and put nail guider, recycle the guide sleeves be arranged on dwang, drill bit is guided to carry out drilling operation to the skeleton after clamping, so only need people's operation just can realize clamping and process of holing the skeleton of fracture, convenient, fast, efficient, be worthy of popularization.
