Abstract
A sliding guide-rotation steel wire guide comprises a handle, a connection rod, a sliding rail, a guide rotation device and a guide tube, wherein the front end of the handle is connected with the tail end of the connection rod; the connection rod is a stainless steel rod in an inverted Z shape; the sliding rail is fixed on the front part of the connection rod; the guide rotation device is mounted on the sliding rail in a slidable manner; and the front end of the connection rod is connected with the guide tube. By using the sliding guide-rotation steel wire guide, stability after reset is greatly raised, thereby facilitating fracture healing and reducing postoperative complications; and the sliding guide-rotation steel wire guide provided by the utility model is simple in structure and convenient to use, and can help to greatly raise accuracy and efficiency of operations.
Description
Technical field
This utility model belongs to medical apparatus and instruments, particularly a kind of for clinically to the free bone folded block after the long bone comminuted fracture change the hole guide-localization, ring is pricked fixing slip and is led the commentaries on classics wire introducer.
Background technology
The long bone of limbs fracture is one of commonly encountered diseases in the orthopaedics clinical position, and along with the development of industrialized society and the aging of social population, various comminuted fracture are also more and more sees.The wire rings of all size that resets-need in the internal fixation operation more of fracture is pricked fixing cracked sclerite, requires in the art to protect the complete of periosteum and surrounding soft tissue as far as possible, guarantees that good blood transports the healing that is beneficial to fracture.There is operating difficulties in conventional metals silk technique for fixing to the free bone folded block, tissue injury is big and fix problems such as insecure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of slip to lead the commentaries on classics wire introducer.
Guide-localization when sclerite is changeed the hole and guiding medical metal silk ring are pricked the slip of bone fixation folded block and are led the commentaries on classics wire introducer.
The technical solution adopted in the utility model is: the commentaries on classics wire introducer is led in a kind of slip, comprises handle, connecting rod, slide rail, leads commentaries on classics device and guiding tube; Described handle front end links to each other with connecting rod is terminal; Connecting rod is anti-Z-shaped stainless steel, and end links to each other with the handle front end; Slide rail is fixedly arranged on the front portion of connecting rod, lead the commentaries on classics device and be slidably mounted on the slide rail, the front end of connecting rod links to each other with guiding tube.
Leading the commentaries on classics device is hollow rustless steel tubulose structure, leads the bottom of changeing device and has a plane.Guiding tube is the stainless steel tube of semicircular arc, and guiding tube front end end face is and leads the acutangulate inclined-plane of central axis that changes device that extended line and the tip, guiding tube front end inclined-plane of leading the central axis that changes device are intersected.The handle front end is conical structure, and the rear end is six prismatic structures, and six in-plane of six prismatic structures have fluted.
After this utility model adopts said structure, after guiding tube is walked around long bone, to lead changes device along the slide rail slip and props up sclerite, under the guide-localization of leading the commentaries on classics device, sclerite is changeed the hole then, the medical metal silk that is used for the ring bundle enters the guiding tube front opening after sclerite is passed in the hole, walk around fracture and pass through the guiding tube open rearward end, withdraw from then and lead the commentaries on classics wire introducer, sclerite is encircled to prick fix.This utility model can be close to bone surface rapidly and pass the fracture surrounding tissue; can protect periosteum and surrounding soft tissue to greatest extent; avoid injured nerve and blood vessel; sclerite is gone to encircle after perforation again and is pricked the fixing stability that has greatly improved after resetting; be conducive to union of fracture, reduced the generation of post-operative complication.It is simple in structure, easy to use, has greatly improved accuracy and the high efficiency of operation technique.
Description of drawings
Accompanying drawing 1 is led for slip of the present utility model changes the wire introducer cutaway view;
Fig. 2 leads the structural representation that changes wire introducer front portion (not comprising handle) for slip of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further details.
As shown in Figure 1, 2, slip of the present utility model is led changes wire introducer mainly by handle 1, connecting rod 2, and slide rail 3 is led and is changeed device 4, and guiding tube 5 is formed.Handle 1 front end is conical structure and links to each other with connecting rod 2 is terminal that the rear end is six prismatic structures, and six in-plane of six prismatic structures have groove.Connecting rod 2 is anti-Z-shaped stainless steel, and end links to each other with handle 1 front end; Slide rail 3 is fixedly arranged on the front portion of connecting rod 2, lead commentaries on classics device 4 and be slidably mounted on the slide rail 3.The front end of connecting rod 2 links to each other with guiding tube 5.
Lead commentaries on classics device 4 and be hollow rustless steel tubulose structure, lead the bottom of changeing device 4 and have a plane, be slidably mounted on the slide rail 3 by this plane, during application, leading commentaries on classics device 4 can be along slip before and after its central axial direction and location.
During use, after guiding tube 5 being close to bone surface and passing soft tissue around the fracture, to lead changes device 4 along slide rail 3 slips and props up sclerite, under the location of leading commentaries on classics device 4, sclerite is changeed the hole then, medical ring is pricked tinsel to be passed and is penetrated by guiding tube prosopyle 5-1 behind the sclerite and stretch out from guiding tube deutostoma 5-2, withdraw from guiding tube 5 then, tighten tinsel and finish the ring bundle of sclerite fixing.
Ultimate principle of the present utility model, principal character and advantage of the present utility model have more than been described.Those skilled in the art should understand; this utility model is not restricted to the described embodiments; under the prerequisite that does not break away from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements all fall in claimed this utility model scope.
