Abstract
The disclosed calcaneal tuberosity fixation clamps of this utility model comprises binding clip (1), retaining mechanism (2) and activity clamp handle interface (3), at the most advanced and sophisticated position of pincers of described binding clip (1), is connected with increased pressure board (4).Utility model arranges increased pressure board by the most advanced and sophisticated 5mm of the pincers at binding clip place, fixedly wound is little, advantage time saving and energy saving, reliable for effect resets to make it both retain manual reduction tibia percutaneous pincers, strengthened again the contact area with calcaneus surface, and make the most advanced and sophisticated degree of depth that enters calcaneus of pincers remain at certain distance (5mm), to what fracture, to squeezing strength, also remain consistent thus, avoiding when fixing calcaneus thrusting calcaneus because of the pincers tip of binding clip causes pressurization to disappear making fracture end occur separated drawback, guaranteed the postoperative reset effect of fracture of calcaneus.
Description
Technical field
This utility model belongs to technical field of medical instruments, and what relate generally to is a kind of calcaneal tuberosity fixation clamps.
Background technology
Calcaneus is the postbrachium of inside and outside arch of foot, and there is considerable influence its form and position to the formation of arch of foot and heavy burden.The rear section of calcaneus, is calcaneal tuberosity.The interior pleurapophysis of calcaneal tuberosity is larger, has Hallux diductor muscle, flexor digitorum brevis to adhere to.The lateral process of calcaneal tuberosity is less, has little unguiflexor to adhere to.Powerful triceps surae is attached to the top of the interior rear side of calcaneal tuberosity by heel string.Calcaneus is mainly comprised of spongy bone, and appearance only has cortical bone as thin as a wafer.There is the age in calcaneal tuberosity epiphysis, general male is 7-11 year, and women is 5-10 year; The epiphyseal arrest time, general male is 14-19 year, and women is 13-18 year.Epiphysis is to organize one of more fragile position.
The damage of calcaneal tuberosity is many by high falling or due to jumping, owing to falling or jumping, and one
As be to contact to earth in calcaneal tuberosity bottom, the easy like this calcaneus that makes is injured in the position of turning up.For adult, generally can cause the vertical shape fracture of the interior rear side of calcaneal tuberosity, the tractive of folded block You Yu Hallux diductor muscle and flexor digitorum brevis and inwardly displaced; For child, can cause the epiphysiolysis of calcaneal tuberosity, folding face is frontal plane, and folded block is upward displacement due to the tractive of triceps surae.If patient is when falling or jump, triceps surae is powerful shrinks, and also can cause the transverse fracture of calcaneal tuberosity, and folding face is closely horizontal, folded block upward displacement.
At present, the clinical Therapeutic Method to calcaneal tuberosity fracture mainly contains:
(1) manual reduction, Gypsum Fibrosum is fixed: the method advantage is without wound, and shortcoming is reset effect
Poor, fixing unreliable.
(2) open reduction, steel plate is fixed: the method advantage is that the reduction of the fracture is good, fixation; Shortcoming is that wound is large, has operation risk, needs second operation to dispel inside-fixture.
(3) manual reduction tibia percutaneous pincers are fixing: the method advantage is that wound is little, and during reset, the motility of maneuver and the organically combination of the mechanicalness of pliers, time saving and energy saving, moment fixation; Shortcoming is, calcaneus is mainly comprised of the less spongy bone of compressive resistance, and only there is cortex as thin as a wafer on surface, during due to reset, need tibia percutaneous pincers to continue calcaneus to pressurize, and very easily little by little thrust in the spongy bone of calcaneus at the pincers tip of binding clip part, causes pressurization to disappear.Usually postoperative about one week, because disappearing, percutaneous pincers pressurization make fracture end occur separation more or less, affect reset effect.
Summary of the invention
The purpose of this utility model produces thus, proposes a kind of calcaneal tuberosity fixation clamps.Use the pressurization of the sustainable maintenance of this fixation clamps to calcaneus, avoid when fixing calcaneus thrusting calcaneus because of the pincers tip of binding clip part and cause pressurization to disappear making fracture end occur separated drawback, guaranteed the postoperative reset effect of fracture of calcaneus.
This utility model is realized the technical scheme that above-mentioned purpose takes: a kind of calcaneal tuberosity fixation clamps comprises a kind of calcaneal tuberosity fixation clamps, comprises binding clip, retaining mechanism and activity clamp handle interface, at the most advanced and sophisticated position of pincers of described binding clip, is connected with increased pressure board.
This utility model is nut at described increased pressure board, at described binding clip, apart from pincers most advanced and sophisticated 5mm position, is provided with screw thread, and the length of screw thread is 3mm, and described increased pressure board and binding clip are threaded connection.
Increased pressure board external diameter described in the utility model is 8mm.
This utility model is in addition improved on the architecture basics of existing tibia percutaneous pincers, by the most advanced and sophisticated 5mm of the pincers at binding clip place, increased pressure board is set, fixedly wound is little to make it both retain manual reduction tibia percutaneous pincers, reset time saving and energy saving, advantage reliable for effect, strengthened again the contact area with calcaneus surface, and make the most advanced and sophisticated degree of depth that enters calcaneus of pincers remain at certain distance (5mm), to what fracture, to squeezing strength, also remain consistent thus, avoiding when fixing calcaneus thrusting calcaneus because of the pincers tip of binding clip causes pressurization to disappear making fracture end occur separated drawback, guaranteed the postoperative reset effect of fracture of calcaneus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, binding clip, 2, retaining mechanism, 3, activity clamp handle interface, 4, increased pressure board, 5, screw thread.
The specific embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1: the calcaneal tuberosity fixation clamps described in the present embodiment is on the basis of the existing tibia percutaneous pincers that are mainly comprised of binding clip 1, retaining mechanism 2, activity clamp handle interface 3, at the most advanced and sophisticated position of pincers of described binding clip 1, be connected with increased pressure board 4.Increased pressure board 4 described in the present embodiment is nut, and the external diameter of pressurizing nut 4 is 8mm.Concrete connected mode is: at binding clip 1, apart from the position of clamping most advanced and sophisticated 5mm, be equipped with screw thread 5, the length of screw thread is 3mm.Increased pressure board 4 is connected by screw thread 5 with binding clip 1.The rear end of binding clip 1 is activity clamp handle interface 3, is conveniently connected with flexible handle.Retaining mechanism 2 consists of locking teeth and lock-screw, and it is arranged on the rear portion on binding clip.
During use, after manual reduction, the pincers tip of this calcaneal tuberosity fixation clamps is fixed on calcaneus, fastening nut also makes it and the surface of calcaneus is close to, because nut is positioned at the most advanced and sophisticated 5mm of pincers, the degree of depth that so just makes the pincers tip of binding clip enter calcaneus remains at 5mm distance, has guaranteed the postoperative reset effect of fracture of calcaneus.The binding clip 1 that simultaneously retaining mechanism 2 has been locked, takes down activity clamp handle, by binding clip, is partly realized the reset of calcaneal tuberosity is fixed.
