Abstract
A kind of point-to-point tibia sight, including：Main body, one end of main body is provided with location graduation, and location graduation is connected with locating rod, the other end of main body is provided with upper guide stop block, lower guide pad is connected by the window frame of visual window with upper guide stop block, the lower hollow of lower guide pad, and the outer of lower guide pad is provided with 14 positioning tooths.In operation, by the way that main body and the supporting external member of sight are assembled, utilize its special structure design, surgical procedure real time inspection can be realized, firm stable is locked to bone tissue, the high purpose of precision is drilled through to tibial tunnel, and operation technique is easy, safe and stable, operating time is shortened, procedure efficiency and surgical quality is improved.
Description
Technical field
The utility model is related to orthopedic medical device technical field, more particularly to a kind of drills through the point pair that tibial tunnel is used
Point tibia sight.
Background technology
In front and rear cruciate ligament reconstruction surgery, drill through tibial tunnel and belong to the critically important part of the operation, drilling through
Tibia sight is used during tibial tunnel, has been international and domestic general method, operation is simple, and effect is good, has gained public acceptance.
Current sight has number of different types, and conventional has point-to-point sight, puts to elbow sight etc., the shape of each producer's sight
Shape size is different, but most of sight is the problem of all have fixed unreliable, sideslip, causes the tunnel being drilled not
It is desired location.And typically also needed using devices such as curets in tunneling process is bored because whether invisible tunnel has been drilled out
Tool coordinate sight use, with its hetero-organization in Saving cortilage chamber, it is cumbersome and be difficult grasp, also need other staff's sometimes
Assist, influence surgical quality.The utility model provide it is a kind of drill through the point-to-point tibia sight that tibial tunnel is used, it is unique
Structure design makes to fix more reliable, and can be clearly apparent whether drill bit has drilled tunnel by arthroscope, is not required to auxiliary using other
Assistant engineer has, simple to operate to be easy to grasp, and substantially increases procedure efficiency and surgical facilitation, improves surgical quality.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of point simple in construction, novel, easy to use
To a tibia sight.
In order to solve the above-mentioned technical problem, the technical scheme of the utility model offer is：A kind of point-to-point tibia sight,
Including：Main body, one end of main body is provided with location graduation, and location graduation is connected with locating rod, and the other end of main body is oriented to provided with upper
Block, lower guide pad is connected by the window frame of visual window with upper guide stop block, the lower hollow of lower guide pad, and lower guide pad
Outer is provided with 2-4 positioning tooth.
In order to preferably solve above-mentioned technical problem, the further technical scheme of the utility model is：Described locating rod
Thinning from one end of the supreme guide stop block in one end of location graduation from being slightly tapered, location graduation one end more slightly ensure that implementation
Stress safety during thrust, upper guide stop block one end is carefully thin, reduces it into damage during human body to human body.
In order to preferably solve above-mentioned technical problem, the further technical scheme of the utility model is：Described positioning is carved
Degree and locating rod be formed in one, upper guide stop block can be formed in one with locating rod, can also by riveting or welding
Mode is fixed.
In order to preferably solve above-mentioned technical problem, the further technical scheme of the utility model is：Described visual window
Window frame has 1-6 roots, is connected by way of riveting or welding with upper guide stop block and lower guide pad.
The utility model has the advantages that：Simple in construction, novel, easy to use, energy real time inspection, locking is firmly steady
Fixed, precision is high, easy to operate, safe and stable, can be accurately performed drilling through for tibial tunnel, shorten operating time, improves
Procedure efficiency and surgical quality.
Brief description of the drawings
Fig. 1 is a kind of structural representation of point-to-point tibia sight of the utility model, wherein：1st, main body, 2, positioning carve
