Detailed description of the invention
The embodiment of the present invention provides a kind of protection spicule, easy for solving spicule of the prior artCause this technical problem of physical inflammation.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present inventionCase is clearly and completely described, and obviously, described embodiment is only one of the present inventionDivide embodiment, instead of whole embodiment. Based on the embodiment in the present invention, this area is generalLogical technical staff is not making the every other embodiment obtaining under creative work prerequisite,All belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 6, a kind of technical scheme of protecting spicule of the embodiment of the present invention comprises:
Needle body 1 and the PEEK sheath 2 that is positioned at needle body 1 outside;
Needle body 1 comprises the self tapping self-drilling type syringe needle 3, threaded portion 4 and the backshank 5 that connect successively,The length of threaded portion 4 is greater than the length of PEEK sheath 2; The inside of PEEK sheath 2 is provided withWith the screwed hole that threaded portion screw thread matches, PEEK sheath 2 is adjustable in the position of threaded portion 4.
Adopt the beneficial effect of technique scheme to be:
Because the protection spicule in the embodiment of the present invention comprises needle body 1 and is positioned at needle body 1 outsidePEEK sheath 2, needle body 1 comprises the self tapping self-drilling type syringe needle 3, the threaded portion 4 that connect successivelyWith backshank 5, the length of threaded portion 4 is greater than the length of PEEK sheath 2; PEEK sheath 2Inside be provided with the screwed hole matching with threaded portion screw thread, in the time that needle body 1 is squeezed in bone, willPEEK sheath 2 is along threaded portion 4 toward backspin, and PEEK sheath 2 is in the position of threaded portion 4Adjustable, until contact with surface of bone, PEEK sheath 2 is placed in needle body 1 outside, can protect skinSkin is avoided the inflammation causing from the injury of screw thread.
Respectively self tapping self-drilling type syringe needle 3, threaded portion 4 and PEEK sheath are carried out in detail belowExplanation.
(1) self tapping self-drilling type syringe needle 3
Self tapping self-drilling type syringe needle 3 can specifically comprise that tapping blade and several move back and cut groove, tappingBlade is positioned at the end of self tapping self-drilling type syringe needle, moves back and cuts the outer surface of groove along self tapping self-drilling type syringe needleCircumferentially arrange.
Further, tapping blade is cone, and this cone is along backshank 5 to self tapping self-drilling type pin3 direction area dwindles gradually.
Further, needle body is formed in one.
Further, several move back and cut groove and uniformly-spaced arrange.
The self tapping of protection spicule is from being drilled with meter and U-shaped screw thread, can time while performing the operation without in advanceDirectly holing in drill point road on bone, and discharges and bore broken bone bits, reduces operating time and bonePin inserts temperature, avoids spicule loosening.
(2) threaded portion 4
Threaded portion screw thread is U-shaped screw thread, and the shape of threaded portion can be cylinder, U-shaped spiral shellLine can increase by 30% bone contact area, reduces radially cortex tension force, and stress is distributed in boneBest.
(3) PEEK sheath 2
PEEK sheath 2 is cylinder, and the outer surface of PEEK sheath 2 is smooth flat.
In the technical scheme of above-mentioned protection spicule, needle body 1 structure that is formed in one, PEEKSheath 2 is placed between needle body 1 and skin, utilizes PEEK (polyether-ether-ketone, English namePolyetheretherketone) outstanding biocompatibility can contact with human body for a long time, can be withHuman body generation stress reaction, protection needle track mouth is not subject to the stimulation of metallic foreign body. Simultaneously again because anti-The screw thread that protects the needle body 1 of spicule is inevitably understood some and is exposed the outer and skin contact of bone,The screw thread of cutting edge can cut skin, and PEEK sheath 2 can be protected the injury of skin from screw threadThe inflammation causing.
The specific works principle of above-mentioned protection spicule is:
First PEEK sheath 2 is screwed to the top of the threaded portion 4 of needle body 1, then will preventsProtect spicule and be inserted in spicule sleeve, use electric drill or manual brace that protection spicule is squeezed in bone,Exit after spicule sleeve, by PEEK sheath 2 along threaded portion 4 toward backspin, until PEEK protectsCover 2 contacts with surface of bone, finally uses medical proof fabric, start in the upper end of PEEK sheath 2 byThreaded portion 4 does not wind up with the part that PEEK sheath 2 contacts, and prevents on the one hand PEEKSheath 2 pines move back, and prevent that on the other hand threaded portion 4 is placed in extraneous screw thread and scratches doctor or patient.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment emphasis is saidBright is all and the difference of other embodiment that between each embodiment, identical similar part is mutualReferring to.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realizedOr use the present invention. The multiple amendment of these embodiment is come those skilled in the artSay it will will be apparent, General Principle as defined herein can do not depart from of the present inventionIn the situation of spirit or scope, realize in other embodiments. Therefore, the present invention will be not can be byBe limited to these embodiment shown in this article, but will meet and principle disclosed herein and newGrain husk feature the widest consistent scope.
