Abstract
The utility model discloses a universal stem holder. The universal stem holder is composed of eight parts including a striking flat head, a handle, a chute rod, a support rotary arm, a locking bolt, a locking nut, a stem conical head liner and a stem shoulder hole guide head. The above parts are integrally combined to be used as a tool for an artificial hip joint for a prosthetic replacement operation. The striking flat head and the handle are fixed on the chute rod to play a role in supporting by a hand and striking by force augmentation at the tail portion. The support rotary arm is fixed in a chute of the chute rod via the locking bolt and the locking nut to play a role in installation, regulation and fastening. The stem conical head liner is fixed with a conical hole at the head portion of the support rotary arm in a matching mode. A conical head of an artificial hip joint prosthetic femoral stem is inserted into a conical hole of the stem conical head liner to be connected and fixed. The stem shoulder hole guide head is in butt joint with a circular hole of a shoulder of the prosthetic femoral stem. After the locking nut is screwed, the universal stem holder is integrally connected with the artificial hip joint prosthetic femoral stem. Implanting operation carried out to a human body is achieved by holding a handle portion with a hand. Compared with a conventional prosthetic tool for an artificial hip joint, the universal stem holder has following characteristics: by employ of a completely-adjustable locking mechanism in a creative way, the universal stem holder is simple and rapid in connection, firm in locking and longer in service lifetime and suitable for femoral stems of numerous types; an artificial hip joint prosthesis operation is enabled to be rapidly and smoothly conducted to the maximum degree; operation time is saved; and recovery of normal physical performance of a hip joint of a patient is achieved rapidly.
Description
Technical field
This utility model relates to a kind of universal handle device of holding, and it is applied to the total hip joint in surgical implant artificial hip joint replacing.
Background technology
There is considerable time in surgical implant Replacement of Hip Joint, wherein prosthese femoral stem, in the time of implant into body, all needs to use a kind of femoral stem implanting instrument.General medical apparatus corporation, Ltd, all can tie-in sale erecting tools in the time selling femoral stem.But these erecting tools are handy or just do not have instrument to sell sometimes at all, this just need to install by the hand-held femoral stem of pinching, and this has higher requirement to the raw technology of the operation traditional Chinese medical science, and what be also unfavorable for performing the operation carries out fast smoothly.At this moment, just need to there is a kind of general, universal handle device of holding of easy-to-install, long-life artificial hip prosthesis's femoral stem to address this problem.
It is all a round bar with handle that common hip prosthesis femoral stem is held handle device, on bar head, has screw thread, being threaded in the reserved screw of femoral stem shoulder when installation on bar head.When this design and installation, need rotating type femoral bone end or femoral stem to hold handle device, quite inconvenient, and hit and install when femoral stem in reinforcing, the as easy as rolling off a log damage of screw screw thread of the screw thread of bar head or femoral stem shoulder causes not dismantling femoral stem after femoral stem installation and holds device.
Although some companies adopt selection high-quality tool materials, material to carry out strengthening the methods such as docking screwed hole diameter in selective hardening raising hardness, design and make up design defect, but because high-quality material is expensive, material selective hardening hardness improves but easy fracture, in design, strengthen docking screwed hole diameter and be only applicable to large size femoral stem, so effect is all not so good.
In sum, at present strong for safe and reliable, simple in structure, the suitability, be easy to install, still there is very large demand in long-life hip prosthesis femoral stem implanting instrument.
Utility model content
This utility model is different from common hip prosthesis femoral stem implanting instrument, and it provides a kind of 3 brand-new fixed artificial hip prosthesis's femoral stem implanting instruments.
In order to realize this utility model object, this utility model adopts following design:
A kind of universal handle device of holding, it is to be made up of strike tack, handle, sliding chute rod, support spiral arm, clamping screw, locking nut, handle conehead liner, handle shoulder hole top guide eight parts.Above-mentioned unit construction becomes after an entirety, can be used as artificial hip prosthesis's replacement operation instrument and uses.Hitting tack and handle is fixed on sliding chute rod, play hand steered holding with afterbody and hit afterburning effect, help spiral arm to be fixed on by clamping screw and locking nut in the groove of sliding chute rod, play to install and regulate and fastening effect, handle conehead liner and artificial hip prosthesis's femoral stem conehead are connected, the circular hole docking of handle shoulder hole top guide and prosthese femoral stem shoulder, screw after locking nut, universally hold handle device and artificial hip prosthesis's femoral stem connects as one, hand-holdable handle portion carries out implant into body operation.Artificial hip prosthesis's instrument of comparing common, the feature of this utility model maximum is the complete scalable locking mechanism of creationary employing, connect simple, connect fast, lock firm, be suitable for that femoral stem model is many, the life-span is longer.This utility model farthest ensures that artificial hip prosthesis performs the operation to carry out fast smoothly, saves operating time, can make the hip joint motion function of the better fast quick-recovery human normal of patient.
Advantage of the present utility model and benefit:
1, universal to hold handle device simple in structure for this utility model, easily manufactures.
2, this utility model universal hold handle device locking and convenient for unlocking firm, simple to operate.
3, the universal handle device of holding of this utility model does not have consumable accessory, in use weares and teares minimum, and tool life is long.
4, the universal handle device of holding of this utility model can use all size model artificial prosthesis, installs compatible strong.
5, the universal handle device handle conehead liner of holding of this utility model adopts medical polypropylene material to make, and other material all adopts medical stainless steel material to make, safe and reliable.
Foregoing has illustrated the beneficial effect of this utility model patented technology scheme fully, below in conjunction with the drawings and specific embodiments, this utility model is further described, so that the public has a better understanding utility model content, the embodiment of detailed description of the invention is best technical scheme, and is not limitation of the utility model.
