Abstract

This utility model relates to a protector for shaft drilling belonging to the clinical surgical apparatus, and it contains a guiding sleeve with an opening for the boring bit. The guiding sleeve connects with C-shaped handle for supporting shaft on one end, while the C-shaped handle also works as baffle for the boring bit, corresponding to the central line of the opening for the boring bit. The protector, simply but scientifically and reasonably structured, is easy to operate, not only ensuring the accuracy in drilling and reducing the exposed tissues, but also protecting the periost and the hinges of soft tissues. Since it facilitates the operation of surgeons and benefits the patients undergoing such operations, it is very easy to promote for application. It is applicable to operations on fracture of all shafts, including femur, shank, humerus, clavicle, ulna, radius, fibula, etc.

Description

Means for protecting diaphysial drilling-hole

Technical field

This utility model relates to the protector in a kind of key boring operation, belongs to clinical surgical instrument.

Background technology

In the extremity operation, how to accomplish both to have appeared clear, avoid accidentally injuring, protect periosteum and soft tissue hinge simultaneously again to the greatest extent to greatest extent, the blood fortune of saving fracture end and sclerite is an an open question still.Still be in two at present extremely, or for operation safety, super scope appears, do not take into account soft tissue hinge and fracture blood fortune, or in order to protect the blood fortune of fracture, blindly operates, and leaves things to chance, it is unfavorable significantly all to exist, and has no alternative.In operation practice, the easiest what cause accidental injury is key boring, the bad location of drilling operation, the boring accuracy is difficult for guaranteeing, organization exposure with protect the contradiction between periosteum and soft tissue hinge more outstanding.

Summary of the invention

The purpose of this utility model is to provide a kind of means for protecting diaphysial drilling-hole, uses easy to operately, can guarantee accurate boring, can significantly reduce to appear tissue protection periosteum and soft tissue hinge again.

Means for protecting diaphysial drilling-hole described in the utility model has the pilot sleeve of a band drill bit bore, and an end of pilot sleeve connects the key handle of supporting of C type, and the key front end double as drill bit baffle plate of supporting handle of C type is corresponding with the centrage of drill bit bore.

During use; directly the key support of C type handle being insinuated into key going up gets final product; no matter the drill bit baffle plate is in which kind of position of key offside; boring can be holed to the backbone exactly; and under the effect of keeping out of drill bit baffle plate, prevent that drill bit from penetrating the damage tissue, protected tissue well; can courageously implement operation technique relievedly, easy and convenient.

On the drill bit baffle plate, establish the drill bit groove that falls through, strengthened surgical drill and felt thoroughly, improve the operation sensitivity, improve the operation quality.

Can be fitted with slide block in pilot sleeve, the equipped back-moving spring in the rear end of slide block is stirred the chute that handle places pilot sleeve on the slide block.In the operation, stir handle backward, slide block retreats, and guarantees key the unlimited comprehensively of handle of supporting of C type, in enforcement clamping process to the backbone, locate postpone, unclamp and stir handle, under the effect of back-moving spring, slide block can eject automatically, and the backbone is clamped, and is in time fixing, makes things convenient for operation technique.

This utility model structure; it is very narrow to make C type backbone support that handle is done; only have that 5mm is wide also can; avoided the large tracts of land of tissue to appear; thereby make periosteum and soft tissue hinge obtain effective protection, and, because the key front end of handle of supporting of C type can tightly slide around the periosteum surface; also avoided the accidental injury of the nerve, blood vessel etc. of key offside, safe and reliable.

On the basis of above-mentioned basic structure, can do some adjustings and improvement, improve serviceability more, as pilot sleeve being designed to telescopic adjustable structure, drill bit bore adjustable size formula structure, or the like.

This utility model is simple in structure; scientific and reasonable; use easy to operately, can guarantee accurate boring, can significantly reduce again and appear tissue; protection periosteum and soft tissue hinge; make things convenient for operative doctor, the patient with operation of being benefited is beneficial to clinical application; be applicable to the fracture operation that all are key, comprise femur, tibia, humerus, clavicle, ulna, radius, fibula etc.

Description of drawings

Fig. 1, this utility model one example structure sketch map.

The vertical view of Fig. 2, Fig. 1.

Among the figure: 1, fall through groove 2, C type of drill bit keyly supported handle 3, slide block 4, stirred handle 5, chute 6, pilot sleeve 7, back-moving spring 8, drill bit bore.

The specific embodiment

The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.

As shown in the figure; means for protecting diaphysial drilling-hole described in the utility model; the pilot sleeve 6 that one band drill bit bore 8 is arranged; one end of pilot sleeve 6 connects the key handle 2 of supporting of C type, and the key front end double as drill bit baffle plate of supporting handle 2 of C type, drill bit baffle plate are provided with the drill bit groove 1 that falls through; the drill bit baffle plate is corresponding with the centrage of drill bit bore 8; be fitted with slide block 3 in the pilot sleeve 6, back-moving spring 7 is equipped with in the rear end of slide block 3, stirs the chute 5 that handle 4 places pilot sleeve 6 on the slide block 3.

When implementing operation, promoting to stir handle 4 backward retreats slide block 3, the key handle 2 of supporting of C type is inserted key offside, make its front end be close to key surface, slowly rotate and insert operation, after insertion finishes, unclamp and stir handle 4, under the effect of back-moving spring 7, slide block 3 ejects, with key clamping, utilize drill bit to implement boring from drill bit bore 8.

Claims

1, a kind of means for protecting diaphysial drilling-hole is characterized in that having the pilot sleeve of a band drill bit bore, and an end of pilot sleeve connects the key handle of supporting of C type, and the key front end double as drill bit baffle plate of supporting handle of C type is corresponding with the centrage of drill bit bore.

2, means for protecting diaphysial drilling-hole according to claim 1 is characterized in that the drill bit baffle plate is provided with the drill bit groove that falls through.

3, means for protecting diaphysial drilling-hole according to claim 1 and 2 is characterized in that being fitted with in the pilot sleeve slide block, and back-moving spring is equipped with in the rear end of slide block, stirs the chute that handle places pilot sleeve on the slide block.
