Description

A kind of nail taking out apparatus in orthopaedics

Technical field

The utility model relates to the field of medical instrument technology, specially a kind of nail taking out apparatus in orthopaedics.

Background technique

Fracture is a kind of common injury, due to the whole world is every year because the case of fracture surgical menopause is much millions of, interior solid It surely is fracture site to be connected after the reduction of the fracture by steel plate and screw, screw is after being implanted into human body, it may occur that environment Medium reaction and alternate stress reaction, bring great pain to patient, so needing to be drawn off in some specific period. Currently used is that pliers takes nail, clamps metal extending part strength with pliers and rotates, usually damages adjacent tissue in this way, or make Fracture site damages again, brings bigger pain to patient, and bone nail concave part is prone to wear, shaking when taking nail is easy to lead Cause takes nail to fail, and increases great work difficulty to medical worker, we have proposed a kind of nail taking out apparatus in orthopaedics thus.

Utility model content

The purpose of this utility model is to provide a kind of nail taking out apparatus in orthopaedics, mentioned above in the background art existing to solve Some pliers take nail easily to cause the secondary injury of patient, and take and will also result in the problem for taking nail difficult when nail built on the sand.

To achieve the above object, the utility model provides the following technical solutions: a kind of nail taking out apparatus in orthopaedics, including lever, It is welded with connecting rod at the top of the lever, handle is welded at the top of the connecting rod, the bottom left axis of the handle connects There is elastic switch, is connected with guiding runner, the lever in the middle part of the top left side of the connecting rod inner cavity and the inner cavity of lever Bottom be welded with clamping head, the junction of the clamping head and lever is bolted with baffle, and the inner cavity middle and lower part of the lever is vertical To fixture is plugged with, the bottom at left and right sides of the fixture is connected with fixture block, offers folder in the middle part of the bottom of the clamping head Mouth is taken, the left and right sides fixture block is respectively positioned on the inner cavity of clipping port, is bolted at the top of the left and right sides of the clipping port flexible Spring, and the outside for being mutually bolted in left and right sides fixture block respectively depending on end of left and right sides adjustable spring, the right side of the elastic switch End is connected with bracing wire, and bracing wire, through the inner cavity of connecting rod and lever, the bracing wire is connected in top guide runner respectively The left and right sides on right side and bottom guiding runner, and the bottom end of partial line is connected to the mutually view of left and right sides fixture block under bracing wire Middle side part.

Preferably, the outer surface of the lever is uniformly provided with antiskid thread.

Preferably, the surface of internal cavity of the clipping port is uniformly provided with internal screw thread.

Preferably, the bottom side Xiang Shi of the left and right sides fixture block is welded with fixed fin.

Compared with prior art, the utility model has the beneficial effects that the New Scheme is more existing during taking nail It is more firm and efficient that pliers takes nail, while also avoiding the secondary injury caused by patient when pliers twists, and doctor is made to exist It takes and can be more accurate when nail and efficiently takes out fixing glue.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the utility model section figure；

Fig. 3 is the utility model fixture schematic diagram.

In figure: 1 lever, 2 connecting rods, 3 handles, 4 elastic switches, 5 guiding runners, 6 baffles, 7 clamping heads, 8 clipping ports, 9 Fixture, 10 fixture blocks, 11 adjustable springs.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1-3, the utility model provides a kind of technical solution: a kind of nail taking out apparatus in orthopaedics, including lever 1 are held The top of handle 1 is welded with connecting rod 2, and the top of connecting rod 2 is welded with handle 3, and the bottom left of handle 3 is connected with elastic switch 4, the top left side of 2 inner cavity of connecting rod and the inner cavity middle part of lever 1 are connected with guiding runner 5, and the bottom of lever 1 is welded with folder First 7 are taken, clamping head 7 and the junction of lever 1 are bolted with baffle 6, and the inner cavity middle and lower part of lever 1 is longitudinally plugged with fixture 9, fixture The bottom of 9 left and right sides is connected with fixture block 10, clamps and offers clipping port 8 in the middle part of the bottom of head 7, and left and right sides fixture block 10 is equal Positioned at the inner cavity of clipping port 8, adjustable spring 11, and left and right sides adjustable spring are bolted at the top of the left and right sides of clipping port 8 11 outside for being mutually bolted in left and right sides fixture block 10 respectively depending on end, the right end of elastic switch 4 is connected with bracing wire, and bracing wire runs through In the inner cavity of connecting rod 2 and lever 1, bracing wire is connected in the right side of top guide runner 5 and the left and right of bottom guiding runner 5 respectively Two sides, and the bottom end of partial line is connected to the mutually view middle side part of left and right sides fixture block 10 under bracing wire.

Wherein, the outer surface of lever 1 is uniformly provided with antiskid thread, and the surface of internal cavity of clipping port 8 is uniformly provided with interior The bottom side Xiang Shi of screw thread, left and right sides fixture block 10 is welded with fixed fin.

Working principle: this programme when in use, catches lever 1 on the other hand, and grasping will clamp head 7 at handle 3 on the other hand The position of 8 alignment and fixation of clipping port nail is entangled, if the screw thread built in clipping port 8 can be used to screw for threaded fixing glue, and After clutch elastic switch 4, bracing wire drives left and right sides fixture block 10 to clamp ailhead inwardly, and baffle 6 can obstruct the slippage of hand It can also preferably have an effect simultaneously, firm rear held stationary gently pulls backward, and fixing glue is finally pulled out fixed position, Then unclamping send switch for locking 4 to restore, and the device is simple and effective, easy to use.
