Description
Technical Field
The utility model relates to a single condyle replacement operation tibial plateau drag hook structure.
Background
In the unicondylar replacement, good surgical field exposure is the key of surgical operation, and the development of surgical auxiliary instruments is lacked at present, so that important soft tissues around the unicondylar replacement are easily damaged during osteotomy, and the insecurity is increased.
Disclosure of Invention
The utility model discloses aim at overcoming prior art's defect, provide a single condyle replacement art tibial plateau drag hook structure, be applicable to and draw open when single condyle replacement art and create the mouth in or outside edge, keep apart and protect the ligament, effectively expose the tibial plateau trailing edge, reduce the operation risk.
In order to solve the technical problem, the utility model discloses a realize like this:
the utility model provides a single condyle replacement operation tibial plateau drag hook structure which characterized in that: the retractor comprises a retractor body, a spacing section and a retractor, wherein at least one end of the retractor body is connected with the retractor through the spacing section to form a three-dimensional retractor structure, the retractor is located on the outer side of one end of the retractor body, the retractor body is a holding portion, and the retractor is a working end.
The tibial plateau drag hook structure for the unicondylar replacement surgery is characterized in that: the two ends of the drag hook body are 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 tibial plateau drag hook structure for the unicondylar replacement surgery is characterized in that: the length of drag hook is 6cm, and the width is 11 mm.
The tibial plateau drag hook structure for the unicondylar replacement surgery is characterized in that: the length of the drag hook body is 12 cm.
The tibial plateau drag hook structure for the unicondylar replacement surgery is characterized in that: the width of drag hook body lower part is greater than the width on upper portion, and the width of drag hook body lower part is 1cm, and the width on drag hook body upper portion is 0.5cm, and drag hook body upper portion and drag hook body lower part's length are 6 cm.
The tibial plateau drag hook structure for the unicondylar replacement surgery is characterized in that: the upper part of the drag hook body and the lower part of the drag hook body are in integrated arc transition connection.
The tibial plateau drag hook structure for the unicondylar replacement surgery is characterized in that: the upper part of the drag hook body is fixedly connected with the lower part of the drag hook body.
The utility model has the advantages that: is beneficial to the holding and the use of a user, and effectively protects the medial collateral ligament at the inner side of the tibial plateau or the lateral collateral ligament at the outer side and important soft tissues at the back. The condition that the operation fails due to the fact that important structures such as medial collateral ligament or lateral collateral ligament are injured in the unicondylar replacement operation is avoided. The safety of the operation is improved, and the operation is convenient.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic structural view of embodiment 1.
Fig. 2 is a schematic structural view of embodiment 2.
Detailed Description
Example 1:
as shown in fig. 1: the utility model provides a single condyle replacement surgery tibial plateau drag hook structure, it includes drag hook body 1, interval section 4 and drag hook 2, the both ends of drag hook body all connect drag hook 2 through the interval section and constitute a three-dimensional structure, and the drag hook at both ends is located drag hook body both sides and symmetry setting respectively, the drag hook body is for the portion of gripping, and the drag hook is the work end. The drag hook at both ends all can be used to the unicondylar replacement art in, when paying attention to the use, hold at drag hook body and interval department, vertically pick up this device and aim at the position that needs the operation with the drag hook end downwards, this device is simple convenient.
Example 2:
in order to avoid the problem that the design of the drag hook in the embodiment 1 can interfere the direction of the user when inserting the drag hook, and is not beneficial to holding, further:
as shown in fig. 2: the drag hook 2 is connected through the interval section to 1 one end of drag hook body and constitutes a three-dimensional structure, the length of drag hook is 6cm, and the width is 11mm, and the length of drag hook body is 12 cm.
Further, the width of drag hook body lower part 12 is greater than the width of upper portion 11, and the width of drag hook body lower part is 1cm, and the width on drag hook body upper portion is 0.5cm, and the length of drag hook body upper portion and drag hook body lower part is 6cm, is favorable to holding and using of user, has effectively protected the inboard medial collateral ligament of tibial plateau or the outside collateral ligament in the outside simultaneously, and the important soft tissue in rear. Important structures such as internal and external collateral ligaments and the like are prevented from being damaged in the unicondylar replacement; the safety of the operation is improved, the operation is convenient, and the condition of operation failure is caused.
Furthermore, the upper part of the drag hook body and the lower part of the drag hook body are in integrated arc transition connection.
Furthermore, the upper part of the drag hook body is fixedly connected with the lower part of the drag hook body.
The draw hook inserts the juncture of tibial plateau and ligament, is used for keeping apart and protecting the ligament in the art and is not wounded by the mistake, simultaneously through the draw hook can be fine expose the art field.
Above-mentioned three-dimensional structure makes things convenient for gripping and work of doctor's hand, can effectively shift the portion of gripping to the outer rear position of keeping away from incision in the art, and the while allows doctor to apply a holding down force to the drag hook working part through the drag hook portion of gripping, prevents during the operation that the drag hook working part from slipping in the shallow ditch of smooth tibial plateau and ligament juncture. The design has the interval section in the three-dimensional structure, further adapts to people's operation custom, has played and has turned to notched back outside with the drag hook portion of gripping, makes the handheld position of drag hook can exert a pressure effect down to the drag hook work portion simultaneously.
