Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bone traction, in particular to a bone traction aiming guide device. Background Technique
[0002] Bone traction treatment is a common operation in clinical orthopedics. It directly traction the bone through Kirschner wire, so as to effectively reduce fractures and dislocations. It has the functions of braking, detumescence and pain relief, and further makes full preparations for orthopedic surgery. For some patients with skin damage, severe swelling, wound infection, severe bone comminution or the elderly and infirm who cannot tolerate surgical internal fixation, bone traction treatment can be carried out until the fracture heals. Common bone tractions include olecranon traction of ulna, supracondylar traction of femur, tibial tubercle traction, calcaneal traction, etc.
[0003] The current bone traction operation is very simple. Only relying on the doctor's experience and sense of direction, it is often difficult to grasp the needle exit point of the contralateral Kirschner wire, resulting in deviation, which affects the traction effect and force line. And when fixing different positions, due to the unchanged size of the traction device, a better traction effect cannot be achieved. Content of the Utility Model
[0004] The purpose of the utility model is to provide a bone traction aiming guide device to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: a bone traction aiming guide device, including a handle. One end of the handle is fixedly connected to the middle of one side of a vertical sleeve seat through a first straight rod. One end of the handle is also fixedly connected to one end of an arc rod through a second straight rod. The other end of the arc rod is provided with a protrusion. The vertical sleeve seat is detachably connected with a syringe barrel. A needle body is slidably connected inside the syringe barrel. The pointed end of the needle body is arranged opposite to the protrusion. A locking screw is arranged on the vertical sleeve seat. A plurality of screw holes are arranged on the syringe barrel. The bottom end of the locking screw extends into the corresponding screw hole to limit and fix the syringe barrel in the vertical sleeve seat.
[0006] Preferably, the handle is provided with a first anti-slip thread.
[0007] Preferably, the outer wall of one end of the syringe barrel is provided with a second anti-slip thread.
[0008] Preferably, both sides of the inner wall of the hollow vertical sleeve seat are provided with chutes. Both sides of the syringe barrel are slidably connected in the chutes through corresponding pulleys.
[0009] Preferably, a scale line is arranged at a position of the needle body close to the pointed end.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] This kind of bone traction aiming guide device clamps the position between the bottom end of the protrusion and the needle outlet end of the syringe on the knee. After finding the position, the tip of the needle body is penetrated into the knee through an external device. During the puncture process, a medical staff member can hold the handle with one hand and hold the syringe away from the needle outlet end with the other hand to complete the puncture, so that this kind of bone traction aiming guide device achieves a better traction effect, is not prone to deviation when guiding the needle body, improves the flexibility and accuracy of the operation of medical staff, and the whole operation process can be operated by one medical staff member, reducing the labor cost.
