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 an employed important apparatus in the surgery implant surgery, and it is squeezed into file in patient's body through holding, beating, for the prosthese implant procedure is got ready.See also shown in Figure 1ly, 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 slidably is sheathed on the body of rod 2, and the internal structure of dop 4 and the link of file are complementary, and two screws 5 are screwed into the sidewall of dop 4 with relative direction.In the time of need holding file, need earlier file to be put into dop 4, reuse spanner lock screw 5, such operating process is smooth and easy inadequately for operation, has reduced operation efficient, fails to reach best result of use.
This shows that above-mentioned existing sliding hammer obviously still has inconvenience and defective, and demands urgently further improving in structure and use.How to found a kind of simple in structurely, it is more convenient, quick to control, load and unload file, and the moment conduction is more reasonable, and the sliding hammer of the new structure accomplished smoothly of being more conducive to perform the operation belongs to the current industry utmost point and needs improved target in fact.
Summary of the invention
The objective of the invention is to, overcome the defective 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, and it is more convenient, quick to control, load and unload file, and the moment conduction is more reasonable; Be more conducive to perform the operation and accomplish smoothly, thereby be suitable for practicality more.
The object of the invention and solve its technical problem and adopt following technical scheme to realize.According to a kind of sliding hammer that the present invention proposes, comprise 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 slidably is sheathed on the body of rod; Locking pin is fixed in the dop sidewall through 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 to be placed in the dop outside, and with locking pin external end head corresponding position inner groovy or through hole is being set.
The object of the invention and solve its technical problem and also can adopt following technical measures further to realize.
Aforesaid sliding hammer, described locking pin inner termination is slightly larger than the thickness of dop sidewall to the length of external end head.
The length of described locking pin inner termination to 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 also is being provided with limiting plate near the 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 the dop sidewall.
The external end head of described locking pin is semicircle or spherical.
The shape of described locking pin inner termination and file groove are complementary.
In sum, the sliding hammer of the present invention, simple in structure, it is more convenient, quick to control, load and unload file, and the moment conduction is more reasonable, is more conducive to perform the operation accomplish smoothly.The present invention has above-mentioned plurality of advantages and practical value; No matter it all has bigger improvement on product structure or function, obvious improvement is arranged technically, and produced handy and practical effect; And more existing sliding hammer has outstanding effect, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention; Understand technological means of the present invention in order can more to know; And can implement according to the content of description, and for let of the present invention above-mentioned with other purposes, feature and advantage can be more obviously understandable, below special act preferred embodiment; And conjunction with figs., specify as follows.
Description of drawings
Fig. 1 is the structural representation of existing sliding hammer.
Fig. 2 is the structural representation of the sliding hammer of the present invention.
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to sliding its specific embodiment of hammer, structure, characteristic and the effect thereof that proposes according to the present invention, specify as after.
See also shown in Figure 2ly, the sliding hammer of the present invention also is provided with locking pin 6 and lock sleeve 7 on the basis of handle 1, the body of rod 2, sliding hammer body 3 and dop 4 structures.
Wherein, dop 4 is fixedly connected with the two ends of the body of rod 2 respectively with handle 1.
Sliding hammer body 3 slidably is sheathed on the body of rod 2.
Locking pin 6 is preferably two groups, is fixed on through elastic component 8 in the opposing sidewalls of dop 4.Preferable; The external end head of locking pin is an arcuate structure such as semicircle, spherical; The shape of inner termination, position and the file groove when being pressed into file are complementary; The total length of inner termination to external end head is slightly larger than the thickness of dop sidewall, to equal the dop sidewall thickness and file depth of groove sum is the best.And also be provided with limiting plate near the inner termination place, and elastic component 8 is two springs that are 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 the dop sidewall.
The sidewall of dop 4 is being provided with through hole with corresponding position, locking pin 6 inside and outside termination.
Lock sleeve 7 rotating dop 4 outsides that are placed in, and inner groovy or through hole are being set with locking pin 6 external end head corresponding positions.
During 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 concealed in the sidewall of dop 4.File is put into dop 4, turn lock sleeve 7, the external end head of locking pin 6 breaks away from the groove or the through hole of lock sleeve 7, and locking pin 6 is inwardly promoted, and inner termination protrudes in the inwall of dop 4, and is pressed in the file groove, thereby locks, holds file.When squeezing into, as prior art, hold handle 1, the sliding hammer body 3 that slides can be squeezed into complete operation in patient's body with file.The sliding hammer of this utility model adopts the self-locking design, and the loading and unloading of file are very easy to, and make operation more easily smooth and easy.
