The utility model discloses one kind to wear silk pincers, including hinged left caliper and right caliper body, and the left caliper tail end forms teeth, is fixedly connected with adjusting gear rack on the inside of right caliper body tail end, teeth are engaged with adjusting gear rack；Left caliper and right caliper body front end are separately connected left clamp arm and right clamp arm；Left caliper and right caliper body top are provided with guidewire lumen, and guidewire lumen one end is connected to left clamp arm or right clamp arm, and the other end is provided with conducting wire part.The utility model solve surgeon carry out it is multiple wear silk knot suture when, have part in the stitch and tie up unstable problem, reduce operating time and promote procedure efficiency；Lockable mechanism realizes locking effect, locking retaining can be carried out in arbitrary position, realize that pliers is fixed automatically, there is no original silk pincers of wearing to occur needing surgeon to carry out holding on pliers and bind, it holds bad or slips the binding occurred loosely, the phenomenon that need to repeatedly binding, reduces operating time and improves procedure efficiency, goes on smoothly operation.
Description
Technical field
The utility model belongs to a kind of medical instrument, and in particular to one kind wears silk pincers.
Background technique
In bone surgery, the application of intramedullary nail technology is very universal.The fixation of intramedullary nail is by wearing silk knotting bundle
The mode of bundle realizes, needs to clamp using to wearing silk in the process.An existing wrench structure of wearing is simple, and structure cannot achieve tightly
Admittedly the purpose to knot.Surgeon carry out it is multiple wear silk knot suture when, in the stitch if there is there is part to tie up loosely
Solid phenomenon, need to increase multiple tie up and fixed intramedullary nail, this process increases operating time.
Utility model content
The utility model be in order to overcome surgeon existing in the prior art carry out it is multiple wear silk knot suture when,
Part is had in the stitch and ties up insecure, need to be increased and multiple be tied up the shortcomings that being fixed intramedullary nail, increasing operating time
And propose, the purpose is to provide one kind to wear silk pincers.
The technical solution of the utility model is:
One kind wearing silk pincers, including hinged left caliper and right caliper body, and the left caliper tail end forms teeth, right caliper body
It is fixedly connected with adjusting gear rack on the inside of tail end, teeth are engaged with adjusting gear rack；Left caliper and right caliper body front end are separately connected left clamp arm
And right clamp arm；Left caliper and right caliper body top are provided with guidewire lumen, and guidewire lumen one end is connected to left clamp arm or right clamp arm, another
End is provided with conducting wire part.
The left clamp arm is identical with right clamp arm structure, and is arranged in mirror symmetry.
The left clamp arm and right clamp arm are hollow tubular structure, by the straight tube connecting with left caliper or right caliper body front end
Portion and for encircling intramedullary nail arc sections composition.
The conducting wire part is by the introduction part inside insertion guidewire lumen and is placed in the enlarged portion group of flare outside guidewire lumen
At.
The side that the adjusting gear rack forms sawtooth is internally provided with the elastic slice for retaining.
The beneficial effects of the utility model are:
The utility model provide it is a kind of wear silk pincers with lockable mechanism, solve surgeon and carry out multiple wearing silk
When knotting suture, part is had in the stitch and ties up unstable problem, reduce operating time and promote procedure efficiency.It has
The silk pincers of wearing of lockable mechanism make rack gear and teeth at clamp handle rear portion, and the rack gear teeth and elastic slice of cooperation can realize locking effect,
Locking retaining can be carried out in arbitrary position, realize that pliers is fixed automatically, occur needing surgeon without original silk pincers of wearing
It carries out holding on pliers and be bound, hold bad or slip the binding occurred loosely, the phenomenon that need to repeatedly binding, reduce hand
The art time improves procedure efficiency, goes on smoothly operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the decomposition texture schematic diagram of the utility model；
Fig. 3 is the enlarged structure schematic diagram of part in the utility model.
Wherein:
1 left caliper, 2 right caliper body
3 teeth, 4 adjusting gear rack
5 left clamp arm, 6 right clamp arm
7 guidewire lumen, 8 conducting wire part.
Specific embodiment
With reference to the accompanying drawings of the specification and embodiment is worn silk pincers to the utility model and is described in detail:
As shown in Fig. 1 ~ 3, one kind wearing silk pincers, including hinged left caliper 1 and right caliper body 2,1 tail end of left caliper
Teeth 3 are formed, are fixedly connected with adjusting gear rack 4 on the inside of 2 tail end of right caliper body, teeth 3 are engaged with adjusting gear rack 4；Left caliper 1 and right pincers
2 front end of body is separately connected left clamp arm 5 and right clamp arm 6；Left caliper 1 and 2 top of right caliper body are provided with guidewire lumen 7, guidewire lumen 7 one
End is connected to left clamp arm 5 or right clamp arm 6, and the other end is provided with conducting wire part 8.
The left clamp arm 5 is identical with 6 structure of right clamp arm, and is arranged in mirror symmetry.
The left clamp arm 5 and right clamp arm 6 are hollow tubular structure, by what is connect with left caliper 1 or 2 front end of right caliper body
Straight sections and for encircling intramedullary nail arc sections composition.
The conducting wire part 8 is by the introduction part inside insertion guidewire lumen 7 and is placed in the enlarged portion of 7 outside flare of guidewire lumen
Composition.
The side that the adjusting gear rack 4 forms sawtooth is internally provided with the elastic slice for retaining.
The application method of the utility model:
In use, after surrounding intramedullary nail with the left clamp arm 5 and right clamp arm 6 of two pairings, by suture from left lead
The enlarged portion of part 8 penetrates, and passes sequentially through guidewire lumen 7 on left caliper 1, left clamp arm 5, right clamp arm 6, the guidewire lumen 7 on right caliper body 2
Afterwards, it is pierced by from the enlarged portion of right side conducting wire part 8, two tail end of suture reserves sufficient length, will then wear silk pincers from surrounding
It is extracted out on intramedullary nail, suture has surround the intramedullary nail to be tied up at this time, then is clamped with this and pressed from both sides close to intramedullary nail outer edge
Tight silk is straightened in tight two suture, once just completes the operation for connecting suture and tightening suture in this way, finally that the pincers are complete
Full extraction.
The utility model provide it is a kind of wear silk pincers with lockable mechanism, solve surgeon and carry out multiple wearing silk
When knotting suture, part is had in the stitch and ties up unstable problem, reduce operating time and promote procedure efficiency.It has
The silk pincers of wearing of lockable mechanism make rack gear and teeth at clamp handle rear portion, and the rack gear teeth and elastic slice of cooperation can realize locking effect,
Locking retaining can be carried out in arbitrary position, realize that pliers is fixed automatically, occur needing surgeon without original silk pincers of wearing
It carries out holding on pliers and be bound, hold bad or slip the binding occurred loosely, the phenomenon that need to repeatedly binding, reduce hand
The art time improves procedure efficiency, goes on smoothly operation.
