Description
Technical field
The utility model relates to a kind of bone holding forcep.
Background technique
With the progress of medical domain, orthopaedics disease can be treated mostly at present.Bone holding forcep are most in orthopaedics therapy
Common medical instrument, bone holding forcep at present include two clamp handles mostly, and the front of two clamp handles is hinged by hinge axis, pincers
The Front-end Design of handle has tong arm, and the rear end of clamp handle is equipped with handle.When performing the operation using this bone holding forcep, surgical staff is needed to use always
Power grasps handle, and holding area is smaller, clamps not strongly admittedly, and the patient gone to sticks and staves to bone is also impracticable, not can be carried out good
Clamping, need to realize treatment by external device, it is not only cumbersome in this way but also increase surgical staff burden.
Utility model content
The purpose of the utility model is to provide a kind of easy to use, firm grip bone holding forcep.
Realizing the technical solution of the utility model aim is: a kind of bone holding forcep, including upper tong arm and lower tong arm；The upper pincers
The middle part of arm and lower tong arm is hinged to scissor-shaped by pin shaft；The upper tong arm and lower tong arm are to curving, and front is equal
Equipped with arc clamping head；The front end of described two arc clamping heads is equipped with clamping end；The rear portion of the upper tong arm and lower tong arm
Equipped with the position limiting structure to relatively rotate between upper tong arm and lower tong arm can be limited after mutual cooperation.
Described two clamping ends are arranged in parallel, and clamping end is cylindrical bump.
The surface of the cylindrical bump is equipped with skid resistance strip.
The position limiting structure includes setting in the post-brachial arc-shaped rack of upper pincers and is arranged in the lower post-brachial convex block of pincers；Institute
Arc-shaped rack is stated towards being evenly equipped with multiple helical teeth along its length on the face of lower tong arm；The convex block is towards setting on the face of upper tong arm
There is the latch being engaged with the helical teeth on arc-shaped rack.
The rear portion of the lower tong arm is equipped with the groove that can accommodate arc-shaped rack.
The rear end of the upper tong arm and lower tong arm is equipped with finger hole.
Using above-mentioned technical proposal, the utility model have it is below the utility model has the advantages that (1) the utility model upper tong arm
With lower tong arm to curving, and front is equipped with arc clamping head, and the front end of two arc clamping heads is equipped with clamping end,
And it can be limited after the rear portion of upper tong arm and lower tong arm is equipped with and cooperates and opposite turn occurs between upper tong arm and lower tong arm
Dynamic position limiting structure can liberate the both hands of surgical staff, alleviate so that clamping is more preferably secured, and relies on position limiting structure
The burden of surgical staff, convenient for the progress of operation.
(2) two clamping ends of the utility model are arranged in parallel, and clamping end is cylindrical bump, increases clamping
Area further increases clamping stability, and can perform the operation to the broken patient of bone.
(3) skid resistance strip is set on the cylindrical bump of the utility model, so that clamping is stronger.
(4) arc-shaped rack of the utility model is equipped with helical teeth, and convex block is equipped with the latch being engaged with helical teeth, so that upper pincers
Arm limits more preferably secured with lower tong arm.
(5) the utility model is provided at the rear portion of lower tong arm can accommodate the groove of rack gear, can reduce rack gear with
The thickness of convex block, it is easy to process.
(6) the utility model is equipped with finger hole in the rear end of upper tong arm and lower tong arm, further facilitates use.
Detailed description of the invention
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, wherein
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the bottom view of the utility model.
Label in attached drawing are as follows:
Upper tong arm 1, arc-shaped rack 1-1, lower tong arm 2, convex block 2-1, groove 2-2, arc clamping head 3, clamping end 3-1, hand
Finger-hole 4.
Specific embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the bone holding forcep of the present embodiment, a kind of bone holding forcep, including upper tong arm 1 and lower tong arm 2.Upper tong arm 1 with
The middle part of lower tong arm 2 is hinged to scissor-shaped by pin shaft.
The front of upper tong arm 1 and lower tong arm 2 is equipped with arc clamping head 3.Two arc clamping heads 3 are and preceding to curving
End is equipped with clamping end 3-1.Two clamping end 3-1 are arranged in parallel, and clamping end 3-1 is cylindrical bump.For
Increase the frictional force between cylindrical bump and bone, in the surface of columnar protrusion setting skid resistance strip.Upper 1 He of tong arm
The rear portion of lower tong arm 2 can limit the limit knot to relatively rotate between tong arm 1 and lower tong arm 2 after being equipped with mutual cooperation
Structure.
