Description

A kind of stitching reparation holdfast

Technical field

This utility model relates to the holdfast that a kind of stitching prosthesis of joint injury is used.

Background technology

Often need to repair damage and promote rehabilitation by surgical operation when tissue is injured.The surgical operation of repair tissue damage usually uses the stitching thread that connects one or more holdfasts to carry out.In the design of holdfast, important is a bit to increase to greatest extent holdfast in in-house maintenance intensity, so as when the stitching thread that connects strain with respect to holdfast the fracture of Jiangdu holdfast or the risk of extracting from organize to greatest extent.A lot of ways are to increase the holdfast size for this reason, but the holdfast operation is arthroscopic surgery, and the holdfast size adds conference and causes increasing destruction to spongy bone.Simultaneously, existing holdfast major part is two threading hole structures, and under this structure, sutural stitching angle is fixed, and seems convenient not when some is performed the operation.

The utility model content

The purpose of this utility model is to provide and a kind ofly can provides for stitching thread the stitching reparation holdfast of multiple stitching angle.

The technical scheme that realizes this utility model purpose is a kind of stitching reparation holdfast, comprises that outer peripheral face is abound with ailhead and the threadless nail tail of screw thread; The overall diameter of described nail tail is less than the overall diameter of ailhead afterbody; Be vertically arranged with a through wires hole on described nail tail.

Described ailhead and nail tail are non-metallic material; The footpath, the end of the screw thread on described ailhead becomes large gradually towards nail tail direction.

Described ailhead and nail tail are metal material; The tapering of the external diameter of the screw thread on described ailhead is greater than the tapering of the core diameter of thread.

The thread form thickness of the screw thread on described ailhead is 0.20mm ~ 0.60mm.

On described nail tail with the equal rounding in junction, aperture of two faces of through wires hole.

Described nail tail cross section is hexagon.

Adopted technique scheme, the utlity model has following beneficial effect: (1) holdfast of the present utility model is non-full thread structure, the nail tail arranges a through wires hole, and the selection of more suture angles is provided in operation for the doctor, has better medical performance structure.

(2) external diameter of nail tail of the present utility model is less than the overall diameter of ailhead afterbody, and such structure makes holdfast of the present utility model have better hold.

(3) this utility model provides metal material and two kinds of full thread holdfasts of non-metallic material, for metal material, the major diameter of thread of ailhead steep-taper and the core diameter of thread of Small Taper provide better self tapping performance for holdfast, can shoot like a cork skeleton, it is minimum that the structure of form of thread thin thickness makes holdfast drop to the damage of skeleton when shooting, thereby strengthened the hold of holdfast.For non-metallic material, footpath, end ailhead becomes large structure backward gradually, makes holdfast have better hold in skeleton.

(4) this utility model arranges rounding at place, the aperture of through wires hole, has guaranteed the smooth and easy slip of stitching thread in the hole, does not all worry that stitching thread is subject to following closely the restriction of pore structure and is subject to the cutting wearing and tearing of corner angle under arbitrarily angled.

Description of drawings

Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail this utility model, wherein according to specific embodiment also by reference to the accompanying drawings

Fig. 1 is a kind of structural representation of the present utility model, and the holdfast main material in figure is nonmetal.

Fig. 2 is another kind of structural representation of the present utility model, and the holdfast main material in figure is metal.

Label in accompanying drawing is:

Ailhead 1,nail tail 2, throughwires hole 3,stitching thread 4.

The specific embodiment

(embodiment 1)

See Fig. 1, a kind of stitching reparation holdfast of the present embodiment is characterized in that: comprise that outer peripheral face is abound withailhead 1 and thethreadless nail tail 2 of screw thread; The overall diameter ofnail tail 2 is less than the overall diameter ofailhead 1 afterbody; Nail is vertically arranged with athrough wires hole 3 ontail 2, andnail tail 2 cross sections are hexagon, is used for being inserted into the hex slot of the handle that sewing system uses.Ailhead 1 andnail tail 2 are non-metallic material; The footpath, the end of the screw thread onailhead 1 becomes large gradually towardsnail tail 2 directions.Onnail tail 2 with the equal rounding in junction, aperture of two faces of throughwires hole 1.

(embodiment 2)

See Fig. 2, the operation of the present embodiment is slightly different with holdfast andembodiment 1, and atfirst ailhead 1 andnail tail 2 are metal material; The tapering of the external diameter of the screw thread onailhead 1 is greater than the tapering of the core diameter of thread.The thread form thickness of the screw thread on 4ailheads 1 is 0.20mm ~ 0.60mm.Stitching thread 4 penetrates from handle hole, and then as shown in Figure 2, around a circle,nail tail 2 is used for coordinating with the handle of sewing system, then can begin to carry out squeezing into of holdfast and perform the operation from two throughwires holes 3.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
