Abstract
The invention relates to a sliding weight comprising a handle, a rod body, a sliding weight body, a clamp head, a locking pin and a locking sleeve. The clamp head and the handle are respectively and fixedly connected with the two ends of the rod body; the sliding weight body is sheathed on the rod body in a sliding manner; the locking pin is fixed in the side wall of the clamp head by an elastic member; a through hole is arranged at the position of the side wall of the clamp head, corresponding to an inner end and an outer end of the locking pin; and the locking sleeve is sheathed outside the clamp head in a rotating manner and is provided with an inner groove or a through hole at the position corresponding to the outer end of the locking pin. According to the invention, by adoption the sliding weight which has a simple structure,, a file can be held, assembled and disassembled more conveniently and quickly, the torque conduction is more reasonable, and an operation can be finished more smoothly.
Description
Technical field
The present invention relates to a kind of operating theater instruments, particularly relate to a kind of sliding hammer.
Background technology
Sliding hammer is the important apparatus using in Srgery grafting operation, and it,, by holding, beating, is squeezed into file in patient body, for prosthese implant procedure ready.Refer to shown in Fig. 1, existing sliding hammer is made up of handle 1, the body of rod 2, sliding hammer body 3, dop 4 and screw 5.Wherein, handle 1 is individually fixed in the body of rod 2 two ends with dop 4, and sliding hammer body 3 is slidably sheathed on the body of rod 2, and the internal structure of dop 4 and the link of file match, and two screws 5 are screwed into the sidewall of dop 4 with relative direction.Need to hold file time, need first file to be put into dop 4, then use spanner lock screw 5, such operating process is smooth and easy not for operation, has reduced operation efficiency, fails to reach best result of use.
As can be seen here, above-mentioned existing sliding hammer, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.How to found a kind of simple in structurely, control, load and unload file more convenient, quick, moment conduction is more reasonable, is more conducive to the sliding hammer of the new structure that operation completes smoothly, belongs to the current industry utmost point and needs improved target in fact.
Summary of the invention
The object of the invention is to, overcome the defect that existing sliding hammer exists, and a kind of sliding hammer of new structure is provided, technical problem to be solved is to make it simple in structure, controls, loads and unloads file more convenient, quick, and moment conduction is more reasonable, be more conducive to operation and complete smoothly, thereby be more suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of sliding hammer proposing according to the present invention, comprises handle, the body of rod, sliding hammer body, dop, locking pin and lock sleeve, wherein: dop is fixedly connected with the two ends of the body of rod respectively with handle; Sliding hammer body is slidably sheathed on the body of rod; Locking pin is fixed in dop sidewall by elastic component; The sidewall of dop is being provided with through hole with corresponding position, the inside and outside termination of locking pin; Lock sleeve is rotating is placed on dop outside, and with locking pin external end head corresponding position, inner groovy or through hole is being set.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid sliding hammer, described locking pin inner termination is slightly larger than the thickness of dop sidewall to the length of external end head.
Described locking pin inner termination to the length of external end head equals dop sidewall thickness and file depth of groove sum.
Described locking pin and elastic component are two groups, are arranged in the opposing sidewalls of dop.
Described locking pin is also being provided with limiting plate near inner termination place.
Described elastic component is two springs, is distributed in the locking pin left and right sides, and spring one end is fixedly connected with limiting plate, and the other end is fixedly connected with dop sidewall.
The external end head of described locking pin is semicircle or spherical.
Shape and the file groove of described locking pin inner termination match.
In sum, sliding hammer of the present invention, simple in structure, control, load and unload file more convenient, quick, moment conduction is more reasonable, is more conducive to operation and completes smoothly.The present invention has above-mentioned plurality of advantages and practical value, no matter it all has larger improvement in product structure or function, there is technically significant progress, and produced handy and practical effect, and more existing sliding hammer has outstanding effect, thereby be more suitable for practicality.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing sliding hammer.
Fig. 2 is the structural representation of sliding hammer of the present invention.
The specific embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment of sliding hammer, structure, feature and effect thereof of proposing according to the present invention, be described in detail as follows.
Refer to shown in Fig. 2, sliding hammer of the present invention, on the basis of handle 1, the body of rod 2, sliding hammer body 3 and dop 4 structures, is also provided with locking pin 6 and lock sleeve 7.
Wherein, dop 4 is fixedly connected with the two ends of the body of rod 2 respectively with handle 1.
Sliding hammer body 3 is slidably sheathed on the body of rod 2.
The sidewall of dop 4 is being provided with through hole with corresponding position, the inside and outside termination of locking pin 6.
Rotating dop 4 outsides that are placed on of lock sleeve 7, and with locking pin 6 external end head corresponding positions, inner groovy or through hole are being set.
When use, rotation lock cover 7, snaps in the inner groovy or through hole of lock sleeve 7 external end head of locking pin 6, and the inner termination of locking pin 6 is hidden in the sidewall of dop 4.File is put into dop 4, turn lock sleeve 7, the external end head of locking pin 6 departs from groove or the through hole of lock sleeve 7, and locking pin 6 is inwardly promoted, and inner termination protrudes from the inwall of dop 4, and is pressed in file groove, thereby locks, holds file.While squeezing into, as prior art, hold handle 1, slip sliding hammer body 3, can squeeze into file complete operation in patient body.This utility model sliding hammer adopts self-locking design, and the handling of file are very easy to, and makes operation more easily smooth and easy.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, any those skilled in the art, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, all still belong in the scope of technical solution of the present invention.
