Description
Technical field
The utility model relates to the field of medical instrument technology, particularly relate to a kind of flexor of the hand tenorrhaphy with leading
Lead device.
Background technique
Flexor of the hand disinsertion is the very common a kind of hand injury of Hand Surgery Emergency.When musculus flexor disinsertion locating for finger
Location status, the contraction for being broken tendon proximal end muscle, it is inappropriate detect etc. can lead to fracture tendon the nearside broken ends of fractured bone it is further
It bounces back in sheath, to can not be successfully the nearside broken ends of fractured bone for finding and pulling out fracture tendon.It is needed at this time in the close of former wound
Row additional cut again is held, the nearside broken ends of fractured bone of fracture tendon is found, is exported by original sheath to former fracture position and carry out operation seam
It closes.Because the smooth elongate resilient of flexor of the hand stndon sheath pipe is small, tendon is soft, generally tendon directly can not be passed through sheath and return to original
Injury region.When treating the damage in the past, rubber tube or Kirschner wire are commonly used from distal end proximally through sheath, then will be broken tendon
The nearside broken ends of fractured bone is connected with rubber tube or Kirschner wire, and back pull will be broken the nearside broken ends of fractured bone of tendon back to former wound.These
Operation there are rubber tube softness be not easy across sheath, Kirschner wire quality it is hard be easy to damage sheath, the tendon broken ends of fractured bone and rubber tube or
The junction of Kirschner wire is easy to slip or junction is rough and diameter is difficult to greatly very much through rough sledding such as sheaths.Make to go smoothly
Art difficulty increases, and operating time extends.Cause to aggravate postoperative adhesion of tendon degree, reduce operative effect, extends rehabilitation duration etc.
Unfavorable result.Therefore, a kind of draw is designed to be reliable, easy to operation, damage sheath small flexor tendons tractor be current techniques
Field needs completing for task.
Summary of the invention
The purpose of this utility model is to provide a kind of structures simply, traction is reliable, easy to operation, it is small to damage to sheath
Flexor of the hand tenorrhaphy tractor.
In order to achieve the above object, the utility model uses following technical scheme, and a kind of flexor of the hand tenorrhaphy is with leading
Lead device is made of draw bar, articulated shaft, upper semi-circle clamp, lower half circle clamp and Saw blade, its main feature is that: the draw bar is
Elongate cylinder bar, the end circumference of one end cut one section of boss for being located at draw bar longitudinal center, the cutting plane of boss
Middle part is equipped with and is laterally hinged with hole, and the arc plate of protrusion is each extended over out on longitudinal tube wall of upper semi-circle clamp bottom end two sides,
The center of arc plate is equipped with the opposite hole that is laterally hinged with, and the arc surface of upper semi-circle clamp is equipped with vertical through hole, upper semi-circle clamp
Fixed lateral Saw blade on the circular arc inner wall of the other end, the lower half circle clamp is identical as upper semi-circle clamp structure, by upper semi-circle
Clamp is opposite with lower half circle clamp tube wall, bottom end protrusion arc plate is inserted on the boss of draw bar after being overlapped mutually, articulated shaft 2
Both ends riveting is fixed after the hinge hole on arc plate and boss, so that upper semi-circle clamp and lower half circle clamp are hinged on traction
On the boss of bar, the tubulose outside diameter after upper semi-circle clamp and lower half circle clamp closure is less than the outside diameter of draw bar, structure
At a kind of flexor of the hand tenorrhaphy tractor.
The length of draw bar described above is 200-250mm.
The length of upper semi-circle clamp described above and lower half circle clamp is 30-50mm.
Upper semi-circle clamp 3 described above is 1-2mm with 5 diameter of vertical through hole on 4 arc surface of lower half circle clamp.
The equal rounding off of edge of draw bar described above, upper semi-circle clamp and lower half circle clamp,
The upper semi-circle clamp of the utility model and lower half circle clamp are hinged on draw bar top, when closure in hollow tubular with
Draw bar forms cylindric entirety, is rotated after sheath by bolted splice and opens upper semi-circle clamp and lower half circle clamp top
End, intermeshes using the Saw blade on its circular arc inner wall is discontiguous, and after clamping flexor tendons broken ends, back pull is drawn
Flexor tendons broken ends traction export sheath is returned to former wound progress operation stitching and passes through sheath back in draw process by bar
Pipe generates closure function power to the upper semi-circle clamp of closure and lower half circle clamp constraint effect, can be secured clamp flexor tendons broken end
End.It is spare that upper semi-circle clamp with the vertical through hole on lower half circle clamp arc surface can penetrate noninvasive suture.
The utility model can safely and fast draw flexor tendons broken end and return to original damage position, while to the greatest extent
The adverse effect to tendon and sheath is reduced, helps to reduce operating difficulty, shortens operating time, mitigate postoperative adhesion of tendon journey
Degree improves operative effect, promotes rehabilitation as early as possible.Structure is simple and novel, traction is reliable, easy to use, has reached goal of the invention.
