Abstract
The utility model discloses a beveled threaded anchor comprising an anchor body. The upper end face of the anchor body angularly inclines to the horizontal plane and is provided with an internal hexagonal duct; the outer wall of the lower portion of the anchor body is provided with a screw thread; the outer wall of the upper portion of the anchor body is provided with a thread hole which is perpendicularly communicated with the inner wall of the internal hexagonal duct; the upper end of each of an inlet and an outlet of the thread hole is provided with a thread groove; the upper ends of the thread grooves are perpendicularly communicated with the upper end face of the anchor body; the lower ends of the thread grooves are communicated with the thread hole. In such a way, the beveled threaded anchor can be obliquely implanted into a bone, the upper end face of the anchor body can be fitted to the surface of the bone, and complications caused the upper end face of the anchor body, stimulating skin, are prevented.
Description
Technical field
This utility model relates to a kind of improvement of band wire holdfast, and particularly a kind of upper surface that can make holdfast body and surface of bone laminating prevents the inclined-plane band wire holdfast of the complication that the upper surface projection of holdfast body produces the stimulation of skin.
Background technology
Holdfast reconnects soft tissue and bone by suture clinically, and holdfast is imbedded stationary burst tendon tissue in sclerotin, to reach the object of tendon knitting.At present, clinical conventional holdfast can be divided into two kinds of metal anchoring nail and biodegradable holdfasts from material.Metal anchoring nail is mostly Titanium holdfast, and fraction is rustless steel holdfast, and titanium is inert metal, and histocompatibility is got well and enough initial constant intensities are provided.The material source of biodegradable holdfast is polylactic acid (PLA) mostly.PLA holdfast is absorbed by body after implanting for general about 2 years completely.
Band wire holdfast of the prior art, it is conical that holdfast body is roughly, and the upper surface of holdfast body is horizontal plane, implant when holdfast when needs diagonal, holdfast top part can be protruded surface of bone, postoperative implantation holdfast place projection, tenderness, skin ulceration even, holdfast exposes, and causes treating unsuccessfully.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of upper surface that can make holdfast body and surface of bone laminating, prevents the inclined-plane band wire holdfast of the complication that the upper surface projection of holdfast body produces the stimulation of skin.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of inclined-plane band wire holdfast, comprise holdfast body, the upper surface of described holdfast body is horizontal by angle setting, the upper surface of described holdfast body is provided with inner hexagonal hole groove, the outer wall of the bottom of holdfast body is provided with screw thread, the outer wall on the top of described holdfast body be provided with through wires hole; Vertical the communicating of inwall of described through wires hole and inner hexagonal hole groove, the import of described through wires hole and the upper end of outlet are provided with wire casing, described wire casing upper end and holdfast body upper surface vertical connection, lower end is communicated with through wires hole.
Preferably, the upper surface of described holdfast body arranges horizontal by 30-60 degree.
The beneficial effects of the utility model are: inclined-plane described in the utility model band wire holdfast can diagonal be implanted bone, and can make the upper surface of holdfast body and surface of bone fit, and prevent the complication that the upper surface projection of holdfast body produces the stimulation of skin.

detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1 to Fig. 3, this utility model embodiment comprises:
A kind of inclined-plane band wire holdfast, comprising: holdfast body 1, and it is conical that described holdfast body 1 is roughly; The upper surface of described holdfast body 1 tilts horizontal by 45 degree, the upper surface of described holdfast body 1 is provided with inner hexagonal hole groove 5, the outer wall of the bottom of holdfast body 1 is provided with screw thread 4, the outer wall on the top of described holdfast body 1 be provided with through wires hole 3, vertical the communicating of inwall of described through wires hole 3 and inner hexagonal hole groove 5.
On the inwall of the inner hexagonal hole groove 5 of the described import that is provided with through wires hole 3, be provided with wire casing 2; The lower end of described wire casing 2 is communicated with the import of through wires hole 3, the upper surface vertical connection of upper end and holdfast body 1; In the external wall of upper portion of described holdfast body 1, outlet corresponding and each through wires hole 3 is provided with wire casing 2; The lower end of described wire casing 2 is communicated with the outlet of through wires hole 3, the upper surface vertical connection of upper end and holdfast body 1.
When operation, one end of suture is fixed on extensor tendon stop, suture is embedded in the wire casing 2 being connected with the import of through wires hole 3, penetrate through wires hole 3 by the import of through wires hole 3 again, and suture is embedded in the wire casing 2 being connected with the outlet of through wires hole 3, then suture is embedded in the clamp groove 8 on the handle 7 of Medical bottle opener, bottle opener body 6 stretches in inner hexagonal hole groove 5, finally rotating Medical bottle opener implants inclined-plane band wire holdfast diagonal in bone, make upper surface and the surface of bone laminating of holdfast body 1, again suture is passed to extensor tendon stop, and tie a knot in the upper end of extensor tendon stop and the other end of suture, make extensor tendon stop be fixed on bone surface.
The beneficial effects of the utility model are: inclined-plane described in the utility model band wire holdfast can diagonal be implanted bone, and can make the upper surface of holdfast body and surface of bone fit, and prevent the complication that the upper surface projection of holdfast body produces the stimulation of skin.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on this utility model rights protection scope.
