Abstract
A kind of deep osteotome of telescopic adjustable limit, for in bone surgery, including handle, connecting rod and cutter head, sleeve is equipped on the outside of the connecting rod, the sleeve bottom is equipped with limit plate, the sleeve is connect with rod slide, connecting rod is equipped with through-hole, spring is equipped in through-hole, the side of spring is equipped with plate washer, the other side of spring is equipped with and blocks, the diameter blocked is greater than the diameter in sleeve upper limit hole, the limit plate that the utility model passes through setting fitting cutter head, to realize the limit of penetraction depth, it prevents firmly excessive during surgery, osteotome penetrates bone face, the depth of feed is difficult to control, there are serious clinical consequences, it is fixed by the flexible position for making limit plate blocked, the depth of limit can be switched fast.The safety that the utility model greatly improves the efficiency and performs the operation in a word alleviates the operating difficulty of doctor, reduces operating time, is suitable for industrialized production.
Description
Technical field
The utility model relates to a kind of osteotomes, especially use in the surgical procedures such as bone surgery, especially osteotomy, belong to
Orthopedic medical device technical field.
Background technique
When carrying out bone surgery, it is often necessary to bone face is truncated, generally chisel is carried out using osteotome at this time and cuts, such as
To spinal osteotomy orthomorphia, tibiofibula bone-culting operation etc..
Traditional osteotome is straight knife, although experienced doctor can adjust chisel shear force degree in art, limits cutting for osteotome
Enter depth, but after the operation of excessive platform, fatigue may be such that the confidence level of experience reduces, and influence the judgement to penetraction depth；
Experience is insufficient sometimes for young doctor, if degree control when percussion firmly is bad, the depth that will lead to feed is difficult to control,
It is possible that serious clinical consequences, such as damage endorchis and nerve root etc..
When therefore carrying out striking chisel to bone face, as can limiting the chisel cutting depth of osteotome, it is related concurrent to may consequently contribute to reduction operation
Disease improves the efficiency and safety of operation.Have not yet to see any dedicated osteotome that can limit depth.
Utility model content
The utility model is directed to the defect of the prior art, provides a kind of deep osteotome of telescopic adjustable limit, can be to cutter head
Built-in length is limited.
Technical problem described in the utility model solves by the following technical programs:
A kind of deep osteotome of telescopic adjustable limit, including handle, connecting rod and cutter head, described connecting rod one end connects handle, another
End connection cutter head, the connecting rod outside are equipped with sleeve, and the sleeve bottom is equipped with limit plate, and limit plate is bonded cutter head.
The above-mentioned deep osteotome of telescopic adjustable limit, the sleeve are connect with rod slide, and the connecting rod is equipped with through-hole, through-hole
Interior to be equipped with spring, the side of spring is equipped with plate washer, and the other side of spring, which is equipped with, blocks, and the diameter blocked is greater than the sleeve upper limit
The diameter in position hole.
The above-mentioned deep osteotome of telescopic adjustable limit, described limit hole setting 3-5, the distance between adjacent two limit hole is 3-
5mm。
The above-mentioned deep osteotome of telescopic adjustable limit, the distance for blocking center to cutter head is h1, and the upper limit hole is extremely
The distance of limit plate bottom is h2, h1-h2=5mm.
The above-mentioned deep osteotome of telescopic adjustable limit, the plate washer are threadedly coupled with connecting rod.
The utility model has the advantage that
The utility model is bonded the limit plate of cutter head by setting, and the limit of Lai Shixian penetraction depth prevents during surgery
Firmly excessive, the depth of feed is difficult to control, and serious clinical consequences occurs, and limit plate is arranged on sleeve, and sleeve can be even
Vertical sliding on bar changes the relative position of limit plate and cutter head by the variation of sleeve vertical position, to cut to cutter head
The size of depth is adjusted；Sleeve is fixed by blocking with limit hole progress position with connecting rod, is blocked and is arranged in connecting rod
In through-hole, can free extension in through-holes, when needing sliding sleeve, making to block is collapsed into through-hole, and sleeve slides up and down, and blocks
After sliding into next limit hole, position is fixed, and thus simple operations can be switched fast limit depth during surgery, quickly to fit
Answer the demand of different patients.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view；
Fig. 2 is the utility model side structure schematic view；
Fig. 3 is the portion A enlarged cross-sectional view in the utility model Fig. 1.
Each label respectively indicates in figure are as follows: 1, handle, 2, sleeve, and 3, limit plate, 4, cutter head, 5, connecting rod, 6, limit hole,
7, it blocks, 8, spring, 9, plate washer, 10, through-hole.
Specific embodiment
Refering to attached drawing 1,2, the utility model includes handle 1, connecting rod 5 and cutter head 4, and described 5 one end of connecting rod connects handle 1,
The other end connects cutter head 4, and sleeve 2 is equipped on the outside of the connecting rod 5, and 2 bottom of sleeve is equipped with limit plate 3, and limit plate 3 is bonded knife
First 4 side face, blade surface of the bottom end of limit plate 3 apart from cutter head have a certain distance, when use osteotome carries out knochenbruch operation
When, under the barrier effect of limit plate 3, cutter head 4 cut bone depth be it is certain, be achieved in osteotome incision limit.
Refering to attached drawing 1,3, the sleeve 2 is slidably connected with connecting rod 5, and the connecting rod 5 is equipped with through-hole 10, sets in through-hole 10
There is spring 8, the side of spring 8 is equipped with plate washer 9, and the plate washer 9 is threadedly coupled with connecting rod 5, and spring 8 can be fixed in through-hole 10,
The other side of spring 8 is equipped with and blocks 7, and 7 diameter of blocking is greater than the diameter of the limit hole 6 being arranged on sleeve 2, blocks 7
Diameter is less than the diameter of through-hole 10, and block 7 can move reciprocatingly in through-hole 10, and blocks and 7 cannot be pierced by limit hole 6, limits
Position hole 6 word order in the vertical direction, when bone is thicker, when the penetraction depth increase needed, then it is adjustable block 7 from it is different
Limit hole 6 cooperate, to adjust the position of limit plate 3 in the vertical direction, it is opposite with cutter head 4 to change 3 bottom end of limit plate
Thus position changes the penetraction depth of cutter head 4.
It when sliding sleeve 2, presses block 7 first, blocked in 7 retraction through-holes 10 at this time, then up and down adjustment sleeve 2, until suitable
Behind suitable position, blocks and 7 pop up through-hole 10 under the action of spring 8, and block in the limit hole 6 on 7 insertion sleeves 2, at this point,
Sleeve 2 is fixed with 5 position of connecting rod.
Refering to attached drawing 2, the limit hole 6 is arranged 3-5, and the distance between adjacent two limit hole 6 is 3-5mm.Limit phase
The adjacent position of two limit holes 6 and the number of limit hole 6 make to adjust every time finer.
Refering to attached drawing 1,2, the distance for blocking 7 centers to cutter head 4 is h1, the upper limit hole 6 to 3 bottom of limit plate
The distance in portion is h2, h1-h2=5mm, the minimum 5mm of the penetraction depth of bone, therefore osteotome is arranged and limits the minimum 5mm of depth.
