Description
Technical field
The present invention relates to medical instruments fields, relate in particular to a kind of fixed structure of human body implantation equipment and with it
Retina prosthese.
Background technology
In clinical treatment, it is frequently necessary to be implanted into human body on some artificial instruments so as to Rehabilitation or patient is helped to obtain
Obtain the physiology technical ability in terms of certain.
Using the fixed form of suture in some traditional implantation process, the fixed form operation difficulty is big, and time-consuming,
Risk factor is also high.
Also some prior arts are to be fixed on using fixing glue by equipment is implanted into tissue, but due to being implanted into position
Put difference or since the thickness at individual difference implantation position position is different, the fixed area length requirement of fixing glue is also different.
For example, retina prosthese is generally fixed to human body macular area, but the eyewall thickness of Different Individual macular area is different, to fixing glue
The thickness requirement of implant part is also different.In order to solve this problem, an elastic buffer portion can be installed in fixing glue
Part adjusts the length of fixing glue fixed area by the component, but elastic buffer unit installation is not often firm, installs bullet
During spring, often positioning is inaccurate for position, and bullet easily tilts to influence the reliability of fixing glue to angle.
In addition, fixing glue is often connected built on the sand in implantation with implantation equipment, influences to be implanted into speed and effect.
The content of the invention
The present invention is intended to provide a kind of fixed structure for being implanted into a kind of convenient, highly reliable human body implantation equipment, in order to
It solves the above problems, the scheme that the present invention uses is as follows：
A kind of fixed structure of human body implantation equipment, including fixed pin structure and implant, fixed pin structure includes nail tip
Portion and nail body portion, nail tip portion are entered through the implant in tissue, and nail body portion includes what is connected with the nail tip portion
Bar portion and the head of a nail portion away from the nail tip portion with the connection bar portion connection are connected, the connection bar portion part passes through
The implant is provided with contractile elastomeric element in the connection bar portion in implant one side deviation head of a nail portion, is implanted into
Body other side is additionally provided in the head of a nail subordinate side for described close to the adjustable in length of the connection bar portion in nail tip portion
Elastomeric element guides the guiding piece of positioning.When in use, nail tip portion is implanted to human body group through implant by equipment is implanted into
In knitting.Due to setting flexible buffer unit on the upside of implant, the connection pole length on the downside of implant can elasticity
Conversion, can adapt to the implantation requirement of different position difference patient, at the same elastomeric element can also ensure to be implanted into equipment it is close
It is fitted on human body implanting tissue, while implantation equipment will not be made to generate excessive pressure to tissue.Elastomeric element exists
It is inconvenient during installation, it is not easy to be aligned, easily be tilted when shrinking, these all cause influence to its reliability, so also following closely
The guiding piece for guiding positioning elastic component is provided on the downside of cap, which helps the convenient installation of elastomeric element, may be used also
Elastomeric element to be guided to move contraction on straight line, avoid shrinking the length tune for deviation effects connecting rod subordinate's side region occur
Section.
Preferably, the elastomeric element is spring, is set in the part that the end of the spring and the implant contact
There is connection gasket, for connection gasket generally using silicagel pad, biocompatibility is preferable, which has certain elasticity, can prevent
Damage when fixing glue is contacted with implant.The connection gasket is fixedly connected with the spring, which can prevent spring from existing
Crooked influence reliability occurs during extruding, while cushion also increases the forced area of spring and implant, avoids stress
Concentration causes to damage to implant.
Preferably, the guiding piece is from the head of a nail portion to the diameter that nail rod portion direction is extended from becoming smaller greatly
Boss, the end of the boss and the nail rod portion are integrally formed and link together.
Preferably, the boss is conical boss.The boss can be pyramid type boss, may be set to be and be similar to
The boss of half-turn spherical shape.
Preferably, it is additionally provided with connecting portion between the downside in the head of a nail portion and the guiding piece, the spring and described
Connecting portion is connected together or is fixedly connected.In order to ensure the reliability shunk, the downside in head of a nail portion and the upside of elastomeric element
It fixes or is closely connected by way of engaging.
Preferably, which is characterized in that inner groovy is provided on the connecting portion, the spring and inner groovy cooperation are tight
Solid be fastened togather.In the present invention, inner groovy can also be not provided with, is closely fastened togather by interference fit.
Preferably, the spring and the connecting portion are fixed together by way of welding or bonding.
Preferably, it is additionally provided on the upside of the head of a nail portion convenient for fixed ailhead during implantation, which is in
Polygonized structure.The cross section of ailhead so that the equipment being implanted into it is fixed up in implantation using polygonized structure
Convenient, implantation is efficient, and effect is good.
Preferably, the disconnecting prevention structure for preventing it from coming off from tissue is additionally provided in the nail tip portion.
Preferably, the nail tip portion is in integrally tapered that the base area in the tapered nail tip portion is more than the connection bar portion horizontal stroke
Area of section.Tapered top bottom surface and the setting of connecting portion difference in areas cause nail tip to form one after tissue is hammered into
It is a that " " structure, the structure can prevent fixing glue from sliding from tissue to influence fixed effect for back-off.
The present invention also provides a kind of retina for containing human body implantation equipment fixed structure in the claims is false
Body.
As improvement, the length in the nail tip portion is between 0.3mm-1.3mm, and the length in the nail rod portion is in 2mm-
Between 4mm.Length setting is more in line with human eyeball's internal structure so that the structure of fixing glue is relatively reliable, and applicability is more
By force, fixation is more convenient.
As being further improved, the fixed pin structure is 2, is respectively arranged at the left and right sides of implant.In this hair
In bright embodiment, fixing glue is traditionally arranged to be two, respectively positioned at the both sides of implant.It is some other it is special in the case of can
To adjust the quantity of fixing glue according to fixed reliability.
Beneficial effects of the present invention：Human body implantation equipment fixed structure in the present invention plants human body by fixed pin structure
Enter equipment to be fixed, the fixed area adjustable in length of fixing glue can meet different fixed positions or same area not
With the different demands of patient individual difference.The guide portion that head of a nail portion end is set can play guiding function to elastomeric element so that
Elastomeric element install convenient, while prevent its bullet to obliquity effects reliability.In addition, the cross section of the head of a nail is generally polygon
Shape, it is more convenient reliable when being implanted into the fixed structure.
