Background
In orthopedic surgery, angle drag hooks are used as common instruments.
In the orthopedic surgery, the difficulty of hip joint replacement is high. In the operation process, tissues such as skin flaps and muscles need to be retracted, so that the joint capsule is in an open state, and the ball-and-socket joint is completely exposed. Then, the surgeon cuts the neck of the femur, pries the head of the femur out of the acetabulum, assembles simulated prostheses in the acetabulum and the femur in sequence after processing the acetabulum, and then assembles the real prosthesis after debugging. In the whole operation process, the angle pull hook participates in the retraction of tissues such as skin flaps, muscles and the like in the whole process. The existing angle draw hook has no rotating part structure and left and right parting, is inconvenient to operate during use, and has unstable drawing fixation to influence the operation effect.
Disclosure of Invention
The utility model aims at providing an angle drag hook, enough provide wider operation field of vision and more stable operation interface for the operation doctor, simultaneously more convenient and fast and laborsaving.
In order to realize the purpose, the utility model discloses a technical scheme be: the angle draw hook is formed by bending an integrated plate and comprises a vertical part, one end of the vertical part is bent to form a first bending part, and an included angle between the vertical part and the first bending part is 90 degrees; the first bending part is bent to form an acting part, and an included angle between the first bending part and the acting part is 135 degrees; the action part is a right-angled trapezoidal plate, the bottom edge of the trapezoid is connected with the first turning part, the two waists extend along the two sides of the first turning part, and the top edge of the trapezoid is a bevel edge; the top edge of the trapezoid and the two waists are in smooth transition through an arc.
The included angles between the top edge of the trapezoid and the two waists are respectively 75 degrees and 105 degrees.
The lengths of the two waists are respectively 2.5mm and 5 mm.
The thickness of the integrated plate is 2 mm.
The other end of the vertical part is folded back to form a continuous ridge shape on the inner side of the vertical part, and the ridge shape is matched with the hand shape, so that a handle part is formed.
The length of the vertical part is 25 cm.
The length of the first bending part is 6 cm.
The utility model has the advantages that: the utility model discloses an above-mentioned structure, through specific effect portion, can provide wider operation field of vision and more stable operation interface, more convenient and fast and laborsaving for the operation doctor. During operation, the prosthesis can be accurately and stably implanted, and the smooth and high-quality operation is ensured.

Detailed Description
In order to make the objects, technical solutions and advantages of the present novel embodiments clearer, the technical solutions of the present novel embodiments will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of the invention.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To maintain the following description of the novel embodiments clear and concise, a detailed description of known functions and known components of the novel embodiments is omitted.
Example 1:
the angle drag hook of the utility model is formed by bending an integrated plate, and comprises a vertical part 1, wherein one end of the vertical part 1 is bent to form a first bending part 2, and an included angle between the vertical part 1 and the first bending part 2 is 90 degrees; the first bending part 2 is bent to form an acting part 3, and an included angle between the first bending part 2 and the acting part 3 is 135 degrees; the action part 3 is a right-angled trapezoidal plate, the bottom edge 3a of the trapezoid is connected with the first bending part 2, the two sides 3b and 3c extend along the two sides of the first bending part 2, and the top edge 3d of the trapezoid is a bevel edge; the top edge 3d of the trapezoid and the two waists 3b and 3c are in smooth transition through an arc.
The included angles between the trapezoidal top edge 3d and the two waists 3b and 3c are 75 degrees and 105 degrees respectively.
The lengths of the two waists are respectively 2.5mm and 5 mm.
The thickness of the integrated plate is 2 mm.
The other end of the vertical part 1 is folded back to form a continuous ridge shape on the inner side of the vertical part 1, and the ridge shape is matched with the hand shape, thereby forming a handle part.
The length of the vertical part 1 is 25 cm.
The length of the first bending part 2 is 6 cm.
In the orthopedic surgery, the complexity of the joint replacement surgery is high, particularly the hip replacement surgery, because the position of the hip joint is deep, the surgical field is exposed with certain difficulty, the design of the angle pull hook is based on the physiological anatomy of the acetabulum, keeping consistent with the abduction angle direction of the acetabulum, stably placing the joint capsule and the glenoid labrum, when the acetabular posterior rim labrum is treated and the acetabulum is bruised, the hook can be pulled at an angle to effectively retract the great tuberosity and prevent the acetabulum from being blocked and bruised, meanwhile, the pulling hook is accurately and stably clamped on the incision of the posterior edge of the acetabulum, the surgical field is more stably and better exposed, the front edge of the acetabulum can be completely exposed by an assistant easily depending on the characteristic that the angle pulling hook is consistent with the abduction angle of the acetabulum, the iatrogenic injury and the soft tissue embedding of the acetabulum are prevented, and the invention of the angle pulling hook provides great help for the efficient exposure of the surgical field of the hip joint in clinical practice.
