Abstract
The utility model discloses a kind of puncture outfits for knee arthroscope Posterior approach being made of elongated circular section puncturing lever and handle, one section of the front of puncturing lever is inclined flat segments, one section of middle part is the segmental arc of indent, indent radian is 135 °, rear portion is vertical section, segmental arc in the middle part of flat segments circular sliding slopes puncturing lever, connection circular arc radian be, middle part segmental arc other end circular sliding slopes puncturing lever posterior vertical section, the radian for connecting circular arc is 135 °, puncturing lever posterior vertical section bottom end is inserted perpendicularly into longitudinal center one end of column handle, and it is fixed by nut thread；The top of puncturing lever flat segments is equipped with lead hole.The utility model realizes establishes Posterior approach from inside to outside, reduces the blood vesssls and nerves injuries risk that may cause, and has saved operating time, and structure is simple, safe and practical, is suitable for promoting the use of.
Description
Technical field
The utility model relates to the field of medical instrument technology, especially relate to a kind of for knee arthroscope Posterior approach
Puncture outfit.
Background technique
Knee arthroscope surgical clinical treatment in, for posterior cruciate ligament injuries, popliteal cyst, episome take out and
The common diseases such as inside/outside side meniscus relief angle damage, generally require to establish solution of the Posterior approach sufficiently to appear knee joint rear
Cut open structure.Traditional knee arthroscope Posterior approach is established usually successively subcutaneous through skin-under Arthroscopy using scalpel
Tissue-musculature-joint capsule establishes Posterior approach.When successively piercing through tissue using scalpel ecto-entad, due to joint capsule
Outer operation is not difficult to control as it can be seen that entering knife direction, is both extended operating time in this way, is also easy to damage knee joint rear
Nervus vasculairs structure haves the defects that risk is big, time-consuming, difficult grasp.Research and develop it is a kind of in advance will be after puncture outfit be inserted into knee joint
Square compartment, then puncture outfit is pierced by through posterior condylar capsule to outside skin, realize it is visible establishes Posterior approach from inside to outside, then one
Aspect can reduce the blood vesssls and nerves injuries risk that joint capsule outer " blind behaviour " may cause, when on the other hand also saving operation
Between.Therefore develop it is a kind of it is easy to use, structure is simple, the puncture outfit of safe and practical knee arthroscope Posterior approach, be this field
Current one of the task for being badly in need of completing.
Summary of the invention
The purpose of this utility model is to provide a kind of knee arthroscope rears easy to use, structure is simple, safe and practical
The puncture outfit of approach.
In order to achieve the above object, the utility model uses following technical scheme, and one kind being used for knee arthroscope Posterior approach
Puncture outfit, be made of elongated circular section puncturing lever and handle, its main feature is that: one section of the front of puncturing lever is inclined straight
Section, one section of middle part are the segmental arc of indent, and indent radian is 135 °, and rear portion is vertical section, in flat segments circular sliding slopes puncturing lever
The segmental arc in portion, the radian for connecting circular arc is 135 °, middle part segmental arc other end circular sliding slopes puncturing lever posterior vertical section, connection
The radian of circular arc is 135 °, and puncturing lever posterior vertical section bottom end is inserted perpendicularly into longitudinal center one end of column handle, and by nut
It is screwed；The top of puncturing lever flat segments is equipped with lead hole, to constitute a kind of wearing for knee arthroscope Posterior approach
Pierce device.
The length of puncturing lever inclination flat segments described above is 40-50mm, and the length of segmental arc is 50-60mm, vertically
The length of section is 90-100mm.
The diameter of puncturing lever described above is 4-5mm.
The inclination flat segments of the utility model puncturing lever can penetrate skin, for being placed in arthroscopic cannula, the lead on top
Through-hole penetrates after guide line to be introduced intra-articular for guiding operation outside joint, and the structure of segmental arc effectively prevents instrument and pass through
To the iatrogenic injury of ligamentaum cruciatum when fossa intercondyloidea, puncturing lever vertical section bottom end is connect by screw with handle, convenient for grasping in art
Change the position and direction of puncture outfit when making at any time.
The utility model realizes due to the above structure, establishes Posterior approach from inside to outside, and reducing may lead
The blood vesssls and nerves injuries risk of cause also saves operating time, and structure is simple, safe and practical, has reached goal of the invention.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, the structure of the utility model, one kind are used for as can be seen from Figure 1
The puncture outfit of knee arthroscope Posterior approach is made of elongated circular section puncturing lever and handle, its main feature is that；The front of puncturing lever
One section is inclined flat segments 2, and one section of middle part is the segmental arc 3 of indent, and indent radian is 135 °, and rear portion is vertical section 4, straight
Segmental arc in the middle part of 2 circular sliding slopes puncturing levers of section, the radian for connecting circular arc is 135 °, and middle part segmental arc other end circular sliding slopes are worn
Thorn stick posterior vertical section 4, the radian for connecting circular arc is 135 °, and 4 bottom end of puncturing lever posterior vertical section is inserted perpendicularly into column handle 6
Longitudinal center one end, and be screwed by nut 5；The top of puncturing lever flat segments 2 is equipped with lead hole 1, to constitute one kind
Puncture outfit for knee arthroscope Posterior approach.
The length of puncturing lever inclination flat segments 2 described above is 40-50mm, and the length of segmental arc 3 is 50-60mm, vertically
The length of section 4 is 90-100mm.
The diameter of puncturing lever described above is 4-5mm.
