Abstract
The invention relates to a tibial plateau drag hook structure for unicondylar replacement, which comprises a drag hook body, a spacing section and a drag hook, wherein at least one end of the drag hook body is connected with the drag hook through the spacing section to form a three-dimensional drag hook structure, the drag hook is positioned on the outer side of one end of the drag hook body, the drag hook body is a holding part, and the drag hook is a working end. The two ends of the drag hook body are respectively provided with drag hooks, and the drag hooks at the two ends are respectively positioned at the two sides of the drag hook body and are symmetrically arranged; the invention is beneficial to the holding and the use of a user, and simultaneously effectively protects the medial collateral ligament on the inner side of the tibial plateau or the lateral collateral ligament on the outer side and important soft tissues at the rear. Avoids the condition that the operation fails because important structures such as medial and lateral collateral ligaments and the like are injured in the unicondylar replacement operation. The safety of the operation is improved, and the operation is convenient.
Description
Technical field
The present invention relates to a kind of single condyle displacement technique tibial plateau hook structures.
Background technique
In single condyle displacement technique, good visual area exposure is the key that surgical procedure, lacks surgery assistor tool at present
Exploitation, leads to the important soft tissue for being easy to damage surrounding when osteotomy, increases insecurity.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of single condyle displacement technique tibial plateau hook structure is provided, is applicable in
Side edge in or beyond wound, isolation and protection ligament, effectively exposure tibial plateau rear are pulled open when Yu Dan condyle displacement technique, are reduced
Operation risk.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of list condyle displacement technique tibial plateau hook structure, it is characterised in that: it includes drag hook ontology, spacer and drawing
Hook, the drag hook ontology at least one end connect drag hook by spacer and constitute a three-dimensional hook structure, and drag hook is located at drag hook
The outside of ontology one end, the drag hook ontology are grip part, and drag hook is working end.
Single condyle displacement technique tibial plateau hook structure, it is characterised in that: the both ends of the drag hook ontology are equipped with
Drag hook, and the drag hook at both ends is located at drag hook ontology two sides and is symmetrical arranged.
Single condyle displacement technique tibial plateau hook structure, it is characterised in that: the length of the drag hook is 6cm, width
For 11mm.
Single condyle displacement technique tibial plateau hook structure, it is characterised in that: the length of the drag hook ontology is 12cm.
Single condyle displacement technique tibial plateau hook structure, it is characterised in that: the width of the drag hook body lower part is big
Width in top, the width of drag hook body lower part are 1cm, and the width of drag hook body upper part is 0.5cm, drag hook body upper part and
The length of drag hook body lower part is 6cm.
Single condyle displacement technique tibial plateau hook structure, it is characterised in that: the drag hook body upper part and drag hook sheet
Body lower part is the connection of integral type arc transition.
Single condyle displacement technique tibial plateau hook structure, it is characterised in that: the drag hook body upper part and drag hook sheet
Body lower part is to be fixedly connected.
The beneficial effects of the present invention are: be conducive to the holding and use of user, while in effective protection tibial plateau
The important soft tissue of the medial collateral ligament of side or the lateral collateral ligament in outside and rear.It avoids in being injured in single condyle displacement technique
The important features such as collateral ligaments or lateral collateral ligament, generation the case where so as to cause operative failure.Increase surgical procedure
Safety facilitates the operation of operation.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the structural schematic diagram of embodiment 1.
Fig. 2 is the structural schematic diagram of embodiment 2.
Fig. 3 is 1 the invention patent of embodiment and usage state diagram of other medical machineries in art.
Specific embodiment
Embodiment 1:
As shown in Figure 1,3: a kind of list condyle displacement technique tibial plateau hook structure, it includes drag hook ontology 1,4 and of spacer
Drag hook 2, the both ends of the drag hook ontology connect drag hook 2 by spacer and constitute a three-dimensional structure, and the drag hook at both ends point
It drag hook ontology two sides and Wei Yu not be symmetrical arranged, the drag hook ontology is grip part, and drag hook is working end.The drag hook at both ends
For in single condyle displacement technique, paying attention in use, hold at drag hook ontology and spacer, the present apparatus is picked up vertically and by drag hook end
Alignment needs operative site downwards, and the present apparatus is simple and convenient.
Embodiment 2:
In order to avoid in embodiment 1, the design of both ends drag hook can interfere direction when user's insertion drag hook, it is unfavorable for
It holds, further:
As shown in Figure 2: 1 one end of drag hook ontology connects drag hook 2 by spacer and constitutes a three-dimensional structure, the drag hook
Length is 6cm, and width 11mm, the length of drag hook ontology is 12cm.
Further, the width of drag hook body lower part 12 is greater than the width on top 11, and the width of drag hook body lower part is
1cm, the width of drag hook body upper part are 0.5cm, and the length of drag hook body upper part and drag hook body lower part is 6cm, are conducive to
The holding and use of user, while the effective protection medial collateral ligament of medial side of tibial plateau or the lateral collateral ligament in outside,
With the important soft tissue at rear.It avoids and injures the important features such as inside and outside collateral ligaments in single condyle displacement technique；Increase operation behaviour
The safety of work facilitates the operation of operation, generation the case where so as to cause operative failure.
Further, drag hook body upper part is that integral type arc transition connects with drag hook body lower part.
Further, drag hook body upper part is to be fixedly connected with drag hook body lower part.
Drag hook is inserted into the intersection of tibial plateau and ligament, is used to be isolated and ligament is protected not accidentally injured in art, lead to simultaneously
Crossing drag hook can be very good to expose visual area.
Above-mentioned three-dimensional structure facilitates the gripping and work of doctor's hand, can be efficiently transferred to grip part far from notch in art
Outer rear position, while one lower pressure, operation are applied to drag hook work department by drag hook grip part when allowing surgical
When in prevent drag hook work department from slipping from the shallow ridges that smooth tibial plateau has a common boundary with ligament.Design has interval in three-dimensional structure
Section, is further adapted to the operating habit of people, plays the rear outside that drag hook grip part is turned to notch, while keeping drag hook hand-held
Position can apply the effect of a lower pressure to drag hook work department.
