A kind of sleeve type device for taking out broken nail, relates to technical field of medical equipment, especially a kind of sleeve type device for taking out broken nail being convenient to be taken out in patient body by broken nail.Sleeve type device for taking out broken nail of the present utility model, it is characterized in that this extractor comprises handle and takes out bar, handle is arranged on and takes out masthead portion, and take out bottom bar and be provided with the taking-up head can clamping broken nail, taking out head is that an inwall arranges female hole, take out on head and be also provided with opening, place wedge block in opening, overthe openings is provided with locking nut, and locking nut is connected with taking-up head by taking out the screw thread that head outer wall is arranged, locking nut and wedge block are with the use of, clamping broken nail.Sleeve type device for taking out broken nail of the present utility model, solve the problem that the broken nail that produces in current orthopaedics internal fixation operation not easily takes out, simplify the taking-up process of broken nail, and in taking-up process the angle of retentivity and size correct, avoid damaging bone, cause secondary injury.
Description
Technical field
This utility model relates to technical field of medical equipment, especially a kind of sleeve type device for taking out broken nail being convenient to be taken out in patient body by broken nail.
Background technology
Along with orthopaedics Internal fixation technology is developed rapidly, the broken nail that a variety of causes causes, disconnected plate case make orthopedist be difficult to the problem of avoiding.Be no matter remove internal fixtion or internal fixtion resets for these cases, all relate to broken nail and take out this thorny problem.In recent years, research worker has had certain progress with regard to the research of device for taking out broken nail aspect.The fracture of steel plate, screw is the problem through often running into after bone surgery.
At present, maximum is utilizes the apparatuses such as tweezers tightly to clamp broken nail to expose part outside bone, then firmly tweezers are rotated backward, broken nail is taken out, in the process, firmly can only rotate, pull out outward by armrest, angle out of strength cannot be ensured and size of exerting oneself, and also because operator do not have power-assisted to cause getting nail slowly, easily additional injuries is caused to bone.
Now, in mechanical connection, the broken nail removing method used first in the middle of broken nail, makes a call to a hole with power drill, then device for taking out broken nail is rotated, device for taking out broken nail surface design is anti-pitch thread, therefore need to be rotated counterclockwise, just can reversely rotate out after action torque is greater than the thread friction moment of torsion of broken nail.
And due to screw medically less, simultaneously human body bone strength is not high yet, therefore, the broken nail removing method that mechanical connection aspect uses, and be not suitable for medical-therapeutic treatment of human body aspect.
Summary of the invention
To be solved in the utility model is exactly in current orthopaedics internal fixation operation, the problem that the broken nail of generation not easily takes out, and provides a kind of sleeve type device for taking out broken nail being convenient to be taken out in patient body by broken nail.
Sleeve type device for taking out broken nail of the present utility model, it is characterized in that this extractor comprises handle and takes out bar, handle is arranged on and takes out masthead portion, and take out bottom bar and be provided with the taking-up head can clamping broken nail, taking out head is that an inwall arranges female hole, take out on head and be also provided with opening, place wedge block in opening, overthe openings is provided with locking nut, and locking nut is connected with taking-up head by taking out the screw thread that head outer wall is arranged, locking nut and wedge block are with the use of, clamping broken nail.
Described opening is three, three opening spaced sets, is all placed with a wedge block in each opening, when being threaded to opening part under locking nut, locking nut compressing wedge block, three pieces of wedge blocks are inwardly shunk, and symmetrical three-point fix firmly will clamp broken nail.
Described extractor also comprises a balanced support sleeve, this balanced support sleeve is arranged on by screw thread and takes out on bar, balanced support sleeve is hollow round table, be connected with taking-up bar by screw thread, taking-up bar and broken nail plane is kept to keep plumbness by balanced support sleeve, avoid, in taking-up broken nail process, because of the problem of stressed generation angular deviation, causing broken nail to cause extra damage to bone.This balanced support sleeve also has a function, namely gives one and broken nail removing direction opposite effect power, makes taking-up bar utilize less power just conveniently can take out broken nail when rotated.
Specifically getting in broken nail process, first balanced support sleeve is placed on the skin at broken nail place, is placed on to broken nail place afterwards, is connected the taking-up head taking out bar after being rotated by female thread with broken nail, rotates to taking out head and bone contact; Rotational lock nut afterwards, oppresses three pieces of wedge blocks in order to step up broken nail, then holds handle, produced counterclockwise by broken nail or extract.
Sleeve type device for taking out broken nail of the present utility model, design science, structure is simple, easy to use, solve the problem that the broken nail that produces in current orthopaedics internal fixation operation not easily takes out, simplify the taking-up process of broken nail, and in taking-up process the angle of retentivity and size correct, avoid damaging bone, cause secondary injury.

Wherein, handle 1, takes out bar 2, takes out 3, hole 4, wedge block 5, locking nut 6, balanced support sleeve 7.
Detailed description of the invention
Embodiment 1: a kind of sleeve type device for taking out broken nail, this extractor comprises handle 1 and takes out bar 2, handle 1 is arranged on and takes out bar 2 top, take out the taking-up 3 being provided with bottom bar 2 and can clamping broken nail, taking out 3 is that an inwall arranges female hole 4, take out on 3 and be also provided with opening, wedge block 5 is placed in opening, overthe openings is provided with locking nut 6, locking nut 6 is by taking out screw thread that 3 outer wall is arranged and taking out 3 and be connected, locking nut 6 and wedge block 5 with the use of, step up broken nail.This opening is three, three opening spaced sets, is all placed with a wedge block 5 in each opening, and when locking nut is threaded to opening part 6 times, locking nut 6 oppresses wedge block 5, and three pieces of wedge blocks 5 are inwardly shunk, clamping broken nail.Extractor also comprises a balanced support sleeve 7, this balanced support sleeve 7 is arranged on by screw thread and takes out on bar 2, balanced support sleeve 7 is hollow round table, be connected with taking-up bar 2 by screw thread, keep taking out bar 2 by balanced support sleeve 7 and keep plumbness with broken nail plane, avoid, in taking-up broken nail process, because of the problem of loading angle, causing broken nail to cause extra damage to bone.
Specifically getting in broken nail process, first balanced support sleeve 7 is placed on the skin at broken nail place, is placed on to broken nail place afterwards, is connected the taking-up 3 of taking out bar 2 rotation after by female thread with broken nail, and rotation is taking-up 3 and bone contact extremely; Rotational lock nut 6 afterwards, oppresses three pieces of wedge blocks 5 in order to step up broken nail, then holds handle 1, produced counterclockwise by broken nail or extract.
