Abstract
This utility model relates to a kind of for the fixing forceps of medical apparatus and instruments in orthopaedics, it is characterized in that: the end of jaw is provided with one group of bill, and described bill is sharp cone distal, and the inner side of bill is provided with inclined-plane.During use, forceps of the present utility model is provided with one group of bill, when opening jaw, a pair of bill can stretch into from both sides encircling arm below and clenching of shaped memory embracing bone plate, after clamping ring arm, the clamp handle of constantly firmly holding with a firm grip, a pair of bill is slowly drawn close, now bill inner side is due to inclined-plane, encircle arm and can along inclined-plane, deviate from bone along with the contraction of jaw and deviate from outward, until whole, encircle arm and be opened, depart from bone, whole device can be simplified taking-up operation, and common shape shape-memory alloy encircling bone bonding plate and shape memory biaxial tension hook.Shorten operating time, be reduced in operation may be to the destruction of healing bone probability, reduced operation risk.
Description
Technical field
This utility model relates to the technical field of medical apparatus and instruments, specifically a kind of for the fixing forceps of medical apparatus and instruments in medical operating orthopaedics, relates in particular to the forceps of shaped memory embracing bone plate and shape memory biaxial tension hook.
Background technology
At present; when treatment fracture patient, need to implant interior fixedly medical apparatus and instruments clinically; after fracture patient rehabilitation; conventionally can take out interior fixedly medical apparatus and instruments; such as using shaped memory embracing bone plate and shape memory biaxial tension hook to fracture in interior fixed reset and fixing process, during the taking-up of marmem product, use needle-nose pliers or crow bar to coordinate taking-up.But in taking-up process, while running into following situation, more difficult taking-up internal fixation device:
1, incision site and the interior fixed product at taking-up position have while departing from;
2, apparatus encircles arm or claw hook and bone laminating when tightr;
At this moment taking out internal fixation device will be very complicated, in the operation of taking-up, may damage firm healing bone, has increased the risk of operation and the time of operation, is unfavorable for patient's further recovery.
Summary of the invention
It is a kind of improved for the fixing forceps of medical apparatus and instruments in orthopaedics that the purpose of this utility model is to provide, it can overcome in the operation of taking out internal fixation device in prior art firm healing bone is damaged, and has increased the risk of operation and the some shortcomings of the time of operation.
To achieve these goals, the technical solution of the utility model is: a kind of for the fixing forceps of medical apparatus and instruments in orthopaedics, it mainly comprises jaw and handle, it is characterized in that: the end of jaw is provided with one group of bill, described bill is sharp cone distal, and the inner side of bill is provided with inclined-plane.
During use, forceps of the present utility model is provided with one group of bill, when opening jaw, a pair of bill can stretch into from both sides encircling arm below and clenching of shaped memory embracing bone plate, after clamping ring arm, the clamp handle of constantly firmly holding with a firm grip, a pair of bill is slowly drawn close, now bill inner side is due to inclined-plane, encircle arm and can along inclined-plane, deviate from bone along with the contraction of jaw and deviate from outward, until whole, encircle arm and be opened, depart from bone, whole device can be simplified taking-up operation, and common shape shape-memory alloy encircling bone bonding plate and shape memory biaxial tension hook.Shorten operating time, be reduced in operation may be to the destruction of healing bone probability, reduced operation risk.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one embodiment.
Fig. 2 be in Fig. 1 B-B to cutaway view.
Fig. 3 be in Fig. 1 A-A to cutaway view.
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model will be further described.
Label in each accompanying drawing is expressed as follows: 1 handle, 2 jaws, 3 bills, 4 inclined-planes, inner side, 5 bottom surfaces, 6 joint faces.
Described in the utility model a kind of for the fixing forceps of medical apparatus and instruments in orthopaedics, it mainly comprises jaw and handle, and its difference with the prior art is: the end of jaw is provided with one group of bill, and described bill is sharp cone distal, and the inner side of bill is provided with inclined-plane.One end of jaw is provided with a rectangular cavity, and the width of cavity is 5-7mm, and the length of cavity is 10-12mm, the range of activity that is arranged so that bill of cavity strengthens, increased its operation flexibility, the end of cavity is provided with one group of symmetrical bill, the rectangular triangle of cross section of bill.Described bill consists of inclined-plane, inner side, two sides, bottom surface and joint face, wherein joint face is fixedly connected with jaw, inclined-plane, the inner side gradient of bill is 30-70 degree, what this gradient made that bill more easily stretches into shaped memory embracing bone plate encircling arm below, and inclined-plane, inner side is triangular in shape and form arc with two sides and be connected.The working end of one group of bill is engaged in the centerline of forceps.The end of jaw is upturned, and the angle of perk is 20-45 degree, and jaw perk makes more easily to insert operative site and vise and encircle arm.It is circular-arc that handle is, and between handle and jaw, by fixture, is connected with spring.
In enforcement, for shaped memory embracing bone plate, consider that each encircles laminating closely to what encircle arm and bone, can use this utility model Special withdrawing forceps to take out operation.
The jaw of this Special withdrawing forceps is symmetrical hook-shaped design, bill is cone-shaped, and bill inner side is with inclined-plane, cone-shaped bill and inclined-plane coordinate, make to encircle arm and more easily depart from bone, described inclined-plane is triangular in shape, the end interlock mutually on the inclined-plane, inner side of one group of bill, the lines of occlusion that its interlock place forms overlaps with the centrage of forceps, object is when opening jaw, a pair of bill can stretch into from both sides encircling arm below and clenching of shaped memory embracing bone plate, after clamping ring arm, the clamp handle of constantly firmly holding with a firm grip, a pair of bill is slowly drawn close, now bill inner side is due to inclined-plane, encircling arm can deviate from bone along inclined-plane along with the contraction of jaw and deviate from outward, until whole, encircling arm is opened, depart from bone, pliers head position is designed to rectangle hollow, and its width is just in time slightly larger than that to encircle the arm of arm wide, in use, when jaw, clamps and encircles arm, and hollow part can, through encircling arm, facilitate bill to stretch into and encircle arm below, handle designs is that circular arc is symmetrical, convenient grasping.For the taking-up of shape memory biaxial tension hook, be also same principle and removing method.
Use forceps of the present utility model, can simplify and take out operation, and common shape shape-memory alloy encircling bone bonding plate and shape memory biaxial tension hook.Shorten operating time, be reduced in operation may be to the destruction of healing bone probability, reduced operation risk.
