Description

Technical Area This invention; a surgery that can be used in surgical fixation surgeries for hip fracture the table is related to the apparatus.

Previous Technique Hip fractures are the most common after wrist fractures in the elderly. It is the second type of fracture encountered and its incidence is gradually increasing. is expected. In surgical fixation operations due to hip fracture, traction apparatus (20) and C-arm fluoroscopy device (19) (iloroscopy device) together is used. traction; to keep the broken pieces apart It is a pulling technique applied to a part of the body, which with the traction apparatus (20) the transaction is being made. C-arm scope device (19) is operated by a staff member. a system that is controlled by the directives and enables the X-ray image to be taken. It is a device. In an operation where the traction apparatus (20) is used, the C-arm must be The scope device (19) is also used. Fracture reduction (fracture reduction) with these two tools Placement of the implants in the bone is done and the position of the implants to be sent to the bone is determined. is done. This is the first and most important step of the operation, because this operation is correct. If it is not done, it is not possible to do the other steps correctly.

The conventional technique outlined above has certain disadvantages and cannot meet the need. These are the operating room tables available on the market. far from meeting the needs. Accordingly, the problems encountered are as follows: -With a fluoroscopy device (19) used by personnel other than the surgery team It is not easy to obtain a suitable image. This percentage is repeated over and over from different angles. the patient and the operating room team are exposed to radiation during each extraction. is exposed.

-Despite all the attention of physicians, a regular view. failure and detection technique due to the inability of the materials to be sent in the appropriate position. There may be fractures that cannot be fused due to errors.

A large part of the energy and time spent in surgeries is c-arm fluoroscopy. device to obtain the appropriate image on the traction table. is spent.

Purpose of BuluSun The purpose of BuluS is; to increase the success rate in hip fracture surgeries.

Thanks to the invention, the success rate of surgery by obtaining a regular x-ray image is being increased.

Another purpose of BuluS; shortening of family residence times. hip fracture surgical fixation operations, on average 90 minutes after anesthesia in progress. When this period is examined, the main process steps and durations are; -10 minutes of washing and covering processes, -10 minutes of taking the patient to the traction table, -10 minutes fracture reduction, Sending detection materials for 20 minutes The total duration of the operation is 50 minutes on average. remaining 40 minutes spent using the C-arm fluoroscopy device (19) and this time corresponds to 44% of the total operation time. This The reason for the long duration is that it is currently used in operations. It is the fact that the scope device (19) and the traction apparatus (20) do not work in harmony with each other.

As a result, it takes time to get the right image. Invention requested to be registered Since these devices cannot be used separately from each other, 40 minutes, as they will perform their functions in harmony with each other. this time decreases to 5 minutes with inaksiinuin.

Another purpose of the invention; the operating room team and the patient's exposure to radiation. reduction in the retention rate. Anteroposterior radiograph of the patient's hip in the current technique On average, on the 4th shot, the half-hip X-ray was born in the 6th shot on average. can be obtained. In addition, since the device location or position cannot be protected, each During shooting, this process is experienced again. 2 images in the same direction as the invention Since it can be taken, anterior-posterior and lateral radiographs can be obtained in one go. There is no need to re-adjust every time. Image with fewer shots It is exposed to approximately 80% less radiation when it is obtained.

Another purpose of the invention; reducing personnel costs. C-arm scope A technician is needed to use the device (19) with the instructions of the physician. A The annual cost of an x-ray technician is approximately 42.000 TL. With the invention, such a As the need disappears, both the costs are low and fewer people is exposed to radiation.

Another purpose of the invention is; inactivation of sterilization during surgery level is maintained. C-arm fluoroscopy device during lateral radiography (19) from the non-sterile area (from the waist to the waist) while the tube portion is rotated from the human bottom. aThe following areas are not considered sterile). This is surgery may pose a risk in terms of sterilization. In addition, thanks to the invention, surgery The decrease in the number of auxiliary personnel in the room increases the sterilization safety. is increasing. Therefore; Invention reduces the risk of infection in operations is expected.

The apparatus developed to achieve the mentioned purposes, one of which is traction. consists of two main parts, one of the display mechanism and the other is occurring. These parts that make up the system work in integration with each other.

Apparatus consisting of traction device and imaging device is mounted on the table.
