Abstract
The utility model discloses an articular process lamina retractor comprising a lamina retractor body, and a connecting portion. The connecting portion extending in a bent manner is arranged below the lamina retractor body. Two sides of the connecting portion are in double arc shapes; the front end of the connecting portion is provided with a tip which is in an open single-arc structure; a shank extending in a bent manner is arranged above the lamina retractor body. When the articular process lamina retractor is in clinical use, the tip is directly abutted to the base bottom of an articular process and attached above a transverse process, the tip effectively hooks up the base bottom of the articular process and holds against the surface of the transverse process to serve as a support point, and a superior articular process, an entry point for a pedicle screw, and a lamina can be exposed fully. Independently exposing the tip of the transverse process is not required, shedding occurs rarely, fewer surgical wounds are caused, and operating time is shortened.
Description
Technical field
This utility model relates to medical apparatus and instruments, relates in particular to a kind of laminectomy retractor using in lumbar surgery.
Background technology
When implementing spinal operation, especially during lumbar surgery, operation part exists deeply, often need be by laminectomy retractor by the other tissue retraction of vertebra, to expose visual area.The use of laminectomy retractor can reach the object of abundant exposure operating field.Conventional method is that laminectomy retractor is fixed on transverse process point, need to peel off like this paraspinal muscle and expose transverse process, need peel off the soft tissue such as paravertebral muscles in a big way, and laminectomy retractor is easily shifted, need repeatedly adjust the position of laminectomy retractor, thereby increase tissue injury, extend operating time.Therefore traditional laminectomy retractor not only easily breaks off relations, and needs to expose transverse process point, is difficult to operation, and operation is caused to inconvenience.
Utility model content
Be intended to overcome prior art defect, providing does not need to expose transverse process point in a kind of lumbar surgery art and is difficult for again slippage, can be satisfied with and appear surgical field of view, and can reduce separate tissue and hemorrhage, easy to use, improves the safety of operation technique and reduces the risk of operation.
For achieving the above object, a kind of articular process type of this utility model laminectomy retractor, comprises laminectomy retractor body, and be with body below the connecting portion that bending extends, described connecting portion two sides are double camber shape, and connecting portion front end is provided with tip, and described tip is opening-like single arc structure; The top of described body is bending and is extended with shank.
Alternatively, the radian of described opening-like single circular arc is 2.36 or 3.14.
Alternatively, the radian of described tip is 3.14, and the width of tip is 0.5-1.5mm, and the sharp spacing of tip is 0.5-1.5cm.
Alternatively, described in, being double camber shape connecting portion two sides radian is 0.52.
Alternatively, described shank is spindle, and the length of shank is 10-15cm.
Alternatively, described shank, body, connecting portion and tip are structure as a whole.
Alternatively, described shank and tip and body and connecting portion adopt insert structure.
The articular process type laminectomy retractor of above structure has the following advantages:
This utility model is when clinical use, tip is directly butted on to the basilar part of articular process, is attached on transverse process, the basilar part of articular process can effectively be caught in tip, and prop up transverse process surface to serve as fulcrum, can fully expose entry point and the vertebral plate of superior articular process, pedicle screw.Do not need to expose separately transverse process point, and difficult drop-off, operation wound and operating time reduced.
Its feature is:
1) connecting portion is double camber type, has reduced tissue and has blocked, convenient operation.
2) the opening radian of tip opening shape list circular arc is made as 2.36 or 3.14, has expanded the face of controlling of articular process, avoids breaking off relations.
3) tip radian is 3.14, and tip width is 0.5-1.5mm, and the sharp spacing of tip is 0.5-1.5cm, has both made laminectomy retractor be difficult for breaking off relations, and avoids again tip damage surrounding tissue, the safety that improves operation process.
4) shank is spindle-type, and assistant is convenient to control, easy to operate, improves the comfort level in assistant's operation process.
5) shank, body, connecting portion and tip are structure as a whole, and are convenient to processing and easy to operate.
6) shank and tip and body and connecting portion adopt insert structure, can be designed to the large, medium and small Multiple Type of Denging, be convenient to the shank of different model and tip to peg graft and use, to adapt to the patient of height fat or thin and all ages and classes and the state of an illness, make the scope of application of this laminectomy retractor wider.
This utility model articular process type laminectomy retractor has reached and has not only fully exposed visual area but also firm fixing effect.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of this utility model articular process type laminectomy retractor.
In figure: 1-shank; 2-body; 3-connecting portion; 4-opening shape list circular arc; 5-tip.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe this utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining this utility model, but not as to restriction of the present utility model.
A kind of articular process type laminectomy retractor shown in Figure 1, the present embodiment provides, comprises laminectomy retractor body 2, and is with body 2 belows the connecting portion 3 that bending extends, and wherein, connecting portion 3 two sides are double camber shape, and its radian is 0.52.Connecting portion 3 front ends are provided with tip 5, and tip 5 is opening-like single circular arc 4 structures; Wherein, the radian of tip 5 is 3.14, and the width of tip 5 is 0.5-1.5mm, and the sharp spacing of tip is 0.5-1.5cm.The radian of opening-like single circular arc 4 is 2.36 or 3.14.The top of body 2 is bending and is extended with shank 1, and shank 1 is spindle.
Shank 1 of the present utility model, body 2, connecting portion 3 and tip 5 can be structure as a whole, and use so more conveniently, and processing technology is also relatively simple.
Shank 1 of the present utility model and tip 5 also can adopt insert structure with body 2 and connecting portion 3, this structure is to be convenient to when peeling off musculus sacrospinalis for difference, tip 5 structures that need different model, in tip, 5 adopt standard insert interface with connecting portion 3 joints, therefore, only need to change different tip 5.Shank 1 also can adopt the handle of different model, to adapt to the different demands of using object.
During use, peel off musculus sacrospinalis, expose after articular process and transverse process root, this laminectomy retractor tip is butted on to the lower edge of superior articular process's basilar part, straddles the root of transverse process, the transverse process of take pulls to outside as propping up the other tissue of the vertebra of naming a person for a particular job, fully expose articular process and vertebral plate, can carry out next step operation.This is easy to operate.
The technical scheme above this utility model embodiment being provided is described in detail, applied specific case herein the principle of this utility model embodiment and embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of this utility model embodiment; , for one of ordinary skill in the art, according to this utility model embodiment, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
