Abstract
The utility model relates to the field of medical equipment, especially, relate to an effort -saving nail pulling device, including the nail pulling mechanism that locates the middle part, hinge in two centre gripping arms of nail pulling mechanism front end and hinge respectively in the centre gripping arm terminal with the terminal link rod of nail pulling mechanism, this device turns into the power of upwards choosing to the staple with the operator to the grip of centre gripping arm, the realization is to quick, effective, laborsaving the choosing of staple, the circumstances that the extra influence that can avoid leading to the fact the knee joint surface of bone in the art and bone are lost.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of effort-saving nail extracting device.
Background technology
Total knee arthroplasty be the surface of bone of knee joint surface serious wear is carried out osteotomy process after, peace
After trying to give a false impression body, knee joint is carried out the operation of function replacement.Owing to needs carry out osteotomy process, so entirely
The operating procedure of knee replacements relates to a lot of fixing apparatus of fixing nail and carries out related surgical behaviour
Taking out the situation of fixing nail after work, existing nail extractor is the most time-consuming, laborious, and easily in art
The additional effect that knee joint surface of bone is caused, or produce the situation of bone loss.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that
A kind of time saving and energy saving and be prevented effectively from knee joint surface of bone and cause the effort-saving nail extracting device of additional effect.
This utility model is to be achieved by the following technical programs:
A kind of effort-saving nail extracting device, including the nail pulling mechanism in the middle part of being located at, before being articulated with nail pulling mechanism
Two clamping limbs of end and be hingedly connected to the link rod of clamping limb end and nail pulling mechanism end, described in pull out
Nailing machine structure includes mechanism shell, is located at the guiding mouth of mechanism shell front end, two be located in mechanism shell
Individual corresponding clamping is upper to move block and is located at the reply bullet that move block afterbody upper with clamping bottom mechanism shell
Spring, described clamping moves block and is provided with for driving its light moved up to come down by clamping limb extruding
Face, two clamping upper shiftings are provided with corresponding clip nail projection inside block, and described clamping limb includes mutually cutting with scissors
The forearm connect and postbrachium, described forearm and postbrachium are respectively equipped with the limited block that direction is consistent in hinged place.
The beneficial effects of the utility model are:
Operator is converted into the power of upwards choosing to fixing nail by this device to the grip of clamping limb, it is achieved
Choosing in quick to fixing nail, effective, labour-saving, can avoid in art causing knee joint surface of bone
Additional effect and the situation of bone loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is main TV structure schematic diagram during this utility model clamping.
Fig. 3 is the main TV structure schematic diagram after this utility model unclamps.
In figure: 1. nail pulling mechanism, 2. clamping limb, 3. link rod, 4. mechanism shell, 5. guide
Mouth, 6. moves block in clamping, 7. returning spring, 8. clip nail projection, 9. forearm, 10. postbrachium,
11. limited blocks.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model,
The utility model is described in further detail with most preferred embodiment below in conjunction with the accompanying drawings.
As it can be seen, this utility model includes the nail pulling mechanism 1 being located at middle part, it is articulated with nail pulling mechanism
Two clamping limbs 2 of front end and be hingedly connected to the link rod 3 of clamping limb end and nail pulling mechanism end,
Described nail pulling mechanism includes mechanism shell 4, is located at the guiding mouth 5 of mechanism shell front end, is located at mechanism
Move block 6 in two corresponding clampings in housing and be located at and upper with clamping bottom mechanism shell move block tail
The returning spring 7 in portion, described clamping moves block and is provided with for driving it upwards to move by clamping limb extruding
Dynamic light landslide surface, two clamping upper shiftings are provided with corresponding clip nail projection 8, described clamping inside block
Arm includes forearm 9 and the postbrachium 10 being hinged, and described forearm and postbrachium are in the hinged place side of being respectively equipped with
To consistent limited block 11.
During use, fixing nail is imported in nail pulling mechanism by guiding mouth, clamping limb of holding with a firm grip, clamping limb
Moving block in extruding clamping, clip nail projection is tight by fixing nail clip, clamping moves block in clamping limb extruding extruding
Moving up under effect, gone out by fixing nail puller, now the returning spring of its rear end is extruded by nail pulling mechanism,
The restoring force that returning spring produces drives clamping limb to reply releasing orientation.
Operator is converted into the power of upwards choosing to fixing nail by this device to the grip of clamping limb, it is achieved
Choosing in quick to fixing nail, effective, labour-saving, can avoid in art causing knee joint surface of bone
Additional effect and the situation of bone loss.
The above is only preferred implementation of the present utility model, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from this utility model principle, it is also possible to make
Some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
