Description

Technical Field

[0001] This utility model belongs to the field of orthopedic technology, and specifically relates to a vertebroplasty positioning device. Background Technology

[0002] As my country enters an aging society, the number of thoracic and lumbar vertebral fractures due to osteoporosis is increasing year by year. Globally, the number of people suffering from vertebral fractures reaches 170 million annually, while in my country, the number reaches 36 million annually. Vertebroplasty, with its minimally invasive advantages, has become the preferred treatment for vertebral fractures in the elderly.

[0003] Vertebroplasty involves a 3mm incision, takes only 15-30 minutes, and can be performed under local anesthesia. Previously, the traditional treatment for vertebral fractures in the elderly was conservative, requiring approximately three months of bed rest. This three-month bed rest not only increases the risk of complications such as pulmonary embolism, cerebral infarction, pressure sores, lung infections, and urinary tract infections, but also exacerbates the psychological and financial burden on patients and their families. Now, vertebroplasty is not only minimally invasive, but patients can also get out of bed the day after surgery and be discharged on the third day. This reduces patient suffering, lowers their financial burden, improves their quality of life, and alleviates the pressure on medical insurance funds.

[0004] Vertebroplasty is performed under C-arm fluoroscopy, which typically requires multiple fluoroscopy sessions to complete. However, the C-arm emits a large amount of X-rays, posing risks to both the surgeon and the patient, and is a significant cause of thyroid disease among healthcare workers. Therefore, it is necessary to design a tool that can reduce the number of fluoroscopy sessions required during surgery. Utility Model Content

[0005] The main purpose of this invention is to provide a vertebroplasty positioning device, which solves the problem that in existing vertebroplasty procedures, multiple fluoroscopy sessions are generally required, and the C-arm emits a large amount of X-rays, which can easily cause harm to the surgeon and the patient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vertebroplasty positioning device, comprising a first main rod and a second main rod, wherein a short rod and a long rod are fixedly connected to the first main rod, the short rod and the long rod are arranged on the same straight line, the short rod and the long rod are arranged perpendicularly to the first main rod, the short rod and the long rod are two centimeters away from the second main rod, and the first main rod and the second main rod intersect perpendicularly.

[0007] Furthermore, both the first and second main rods are provided with scale lines.

[0008] Furthermore, the first main rod, the second main rod, the short rod, and the long rod are all made of Kirschner wires.

[0009] Compared with the prior art, this utility model has the following beneficial effects: This utility model has a simple structure by setting a first main support rod, a second main support rod, a long rod, and a short rod. By comparing the short rod and the long rod with the second main support rod under fluoroscopy, the left and right sides of the vertebral body can be distinguished. The short rod and the long rod can be distinguished as above and below the vertebral body under fluoroscopy. Therefore, this locator can locate the upper, lower, left, and right positions of the vertebral body under fluoroscopy in one go, saving the number of fluoroscopy sessions, reducing X-ray damage to the surgeon and patient, and saving surgical time. It also significantly improves the patient's pain and bleeding during surgery. The first main support rod, the second main support rod, the short rod, and the long rod are all made of Kirschner wires, which are simple in structure and extremely inexpensive, making it very economical.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] See Figure 1 This utility model discloses a vertebral body locator for vertebroplasty, comprising a first main support rod 1 and a second main support rod 2. A short rod 3 and a long rod 4 are fixedly connected to the first main support rod 1, arranged in a straight line and perpendicular to the first main support rod 1. The distance between the short rod 3 and the long rod 4 and the second main support rod 2 is two centimeters. The first main support rod 1 and the second main support rod 2 intersect perpendicularly. The intersection point of the first main support rod 1 and the second main support rod 2 is the bull's eye sign, which is the projection of the pedicle of the thoracic and lumbar vertebrae in anteroposterior fluoroscopy. According to surgical positioning standards, the puncture needle positioning point should be located above and outside the bull's eye sign, and the skin insertion point should be 1.0-1.5 cm outside and outside the bull's eye sign. This intersection point is the intraoperative positioning point for the vertebral body.

[0015] Furthermore, both the first main rod 1 and the second main rod 2 are provided with scale lines 5. Preferably, the scale on the scale line 5 is one centimeter.

[0016] Furthermore, in this utility model, the first main rod 1, the second main rod 2, the short rod 3, and the long rod 4 are all made of Kirschner wires, which has a simple structure, extremely low cost, and is very economical.

[0017] The principle of this invention is as follows: the short rod 3 and the long rod 4 can be compared with the second main rod 2 under fluoroscopy to distinguish the left and right sides of the vertebral body, and the short rod 3 and the long rod 4 can be compared with the upper and lower sides of the vertebral body under fluoroscopy. Therefore, this locator can locate the upper, lower and left and right positions of the vertebral body under fluoroscopy in one go, saving the number of fluoroscopy sessions, reducing the damage of X-rays to the surgeon and the patient, saving surgical time, and significantly improving the patient's pain and bleeding during the operation.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
