Abstract
The utility model discloses a flower-shaped anchoring nail, which is a hollow tube. Open type lids are arranged at the both ends, a side lug is arranged at the front end of the anchoring nail, longitudinal diamond deformation grooves are arranged on the tube wall, deformation bridges are formed between the grooves, internally sunk concave hollow ditches are arranged on the outer wall at both ends of the hollow tube, and outward opened concave ditches are arranged on the inner wall of the tube at the narrowest part of the deformation bridge. The flower-shaped anchoring nail of the utility model can be deformed under the squeezing of a special equipment, which cause the deformation bridge to extrude outward and fold to form an anchoring hook, to transversely squeeze and fix the muscle tendon; the side lug can hook the muscle tendon to longitudinally pull and fix the muscle tendon; thus, the utility model not only have the double functions of longitudinal traction fixing and transverse squeeze fixing, but also have the simple operation.
Description
One, technical field
This utility model relates to a kind of medical apparatus and instruments, more particularly about a kind of bone surgery that is used for materials such as tendon, artificial ligament is fixed to colored shape holdfast in the bone.
Two, background technology
In a lot of bone surgeries, need tendon transplantation and tendon is fixed in the sclerotin, such as the cruciate ligaments of knee joint reconstruction operations.Fixedly the method for tendon roughly is divided into four classes:
One class is that bone surface is fixed, and such as tendon is sewn on the bone surface, or by screw, equipment such as door staple are fixed, and the method shortcoming is an open surgery, and utilization is limited in scope;
Two classes are that the bone bridge is fixed, and just tendon are penetrated to pass the back behind the bone hole again from another bone hole and form annular loop tendon is fixed, and the method shortcoming is an operating difficulties, needs cutting operation etc.;
Three classes are vertically fixing, tendon is passed the bone marrow road after the terminal post that rams fix, such as Endo-button, the method shortcoming is that tendon and symphysis are insecure;
Four classes are crosswise fixed, tendon are squeezed on the wall in bone marrow road, and such as the interface nail, the method shortcoming is vertically fixing not firm.
Three, utility model content
The purpose of this utility model provides a kind ofly possesses promptly that vertical tractive is fixing to possess fixedly two-fold advantage of horizontal extruding again, is particularly suitable for the colored shape holdfast of the arthrocsopic surgery of non-opening.
These and other purpose of the present utility model will and be described by following detailed description and further represent.
Colored shape holdfast of the present utility model, it is a hollow pipe, two ends are the open type lid, have at the holdfast front end and to pick up the ears, have vertical diamonding groove on the tube wall, form the distortion bridge between groove and the groove, on the outer wall of hollow pipe two ends, having the shallow concave groove that caves in, have outside chase on the inner-walls of duct at narrow place at the distortion bridge.
Further, above-mentioned distortion groove quantity is 6～8, and distortion bridge quantity is 6～8, and the quantity of picking up the ears is 2～4.
Deformation can take place in colored shape holdfast of the present utility model under the extruding of use particular instrument, make outside outstanding the folding of distortion bridge, forms grasp, laterally pushes fixing to tendon; But the then hook tendon of picking up the ears is fixed the vertical tractive of tendon; Like this, vertical tractive is fixing to possess fixedly dual function of horizontal extruding again to this utility model with regard to promptly possessing, and simple to operate.
Four, description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a side view of the present utility model.
Among the figure, symbol 1 is represented the open type lid, symbol 2 representative distortion grooves, and symbol 3 representative distortion bridges, symbol 4 is represented chase, and symbol 5 representatives are picked up the ears.
The specific embodiment
Below in conjunction with description of drawings structure of the present utility model.
Colored shape holdfast of the present utility model, it is a hollow pipe, two ends are the open type lid, have at the holdfast front end and to pick up the ears, have vertical diamonding groove on the tube wall, form the distortion bridge between groove and the groove, on the outer wall of hollow pipe two ends, having the shallow concave groove that caves in, have outside chase on the inner-walls of duct at narrow place at the distortion bridge.
This utility model is " compressive deformation " structure, and after this holdfast was subjected to longitudinal pressure, dilatancy made the distortion bridge be folded to form grasp along the chase of holding successfully in advance behind outer process, inserts within the sclerotin, plays crosswise fixed holdfast self and the fixedly effect of tendon.And the structure of picking up the ears of holdfast, but tractive tendon then and prevents its slippage, guarantees vertically fixingly, and holdfast front opening formula lid is used to cooperate the use of pushing apparatus, and the lid of rear end then is used to take out this holdfast.
Claims (4)
1, a kind of colored shape holdfast, it is a hollow pipe, it is characterized in that managing two ends is the open type lid, have at the holdfast front end and to pick up the ears, have vertical diamonding groove on the tube wall, form the distortion bridge between groove and the groove, on the outer wall of hollow pipe two ends, having the shallow concave groove that caves in, have outside chase on the inner-walls of duct at narrow place at the distortion bridge.
2, colored shape holdfast according to claim 1 is characterized in that described distortion groove quantity is 6～8.
3, colored shape holdfast according to claim 1 is characterized in that described distortion bridge quantity is 6～8.
4, colored shape holdfast according to claim 1 is characterized in that the described quantity of picking up the ears is 2～4.
