Auxiliary positioning device for minimally invasive surgery of spine

Abstract

The invention relates to an auxiliary positioning device for the minimally invasive surgery of the spine. The problem is effectively solved that when a doctor carries on the minimally invasive surgeryof the spine, a puncture needle cannot be quickly and precisely inserted in a target part of a patient. According to the technical scheme, the device comprises a universal positioning device, the doctor makes the universal positioning device precisely corresponding to the path set in advance with the help of X-ray, so that the puncture needle enters the body of the patient in the pointing direction (the path set in advance) of a positioning cylinder, the puncture needle precisely reaches the lesion part of the spine of the patient accordingly, and X-ray irradiation is also reduced in the puncture process. The doctor can basically move the universal positioning device to the target part of the patient through a transverse adjustment device, a longitudinal adjustment device and a vertical adjustment device, by adjusting the universal positioning device, the positioning cylinder precisely corresponds to the path set in advance, and the device is convenient and quick to operate and high in practicability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary positioning device for spinal minimally invasive surgery. Background technique [0002] Minimally invasive spinal surgery has been widely carried out at present. Compared with traditional spinal surgery, it has the advantages of small surgical incision, small tissue trauma, less bleeding, and faster postoperative functional recovery; [0003] In conventional spinal minimally invasive surgery, the doctor completes the surgical positioning by visually measuring the angle and distance of the surgical instrument relative to the path of the surgical object in frontal and lateral X-ray images based on surgical experience and skills, and adjusting the surgical instrument so that it coincides with the ideal surgical path , this method relies heavily on the doctor's surgical experience and skills. Due to the complexity of the anatomical structure of the spine and the ...

Problems solved by technology

[0003] In conventional spinal minimally invasive surgery, the doctor completes the surgical positioning by visually measuring the angle and distance of the surgical instrument relative to the path of the surgical object in frontal and lateral X-ray images based on surgical experience and skills, and adjusting the surgical instrument so that it coincides with the ideal surgical path , this method relies heavily on the doctor's surgical experience and skills. Due to the complexity of the anatomical structure of the spine and the limitations of the doctor's means of observing the spine, the operation is very difficult. The position of the lesion, that is, the position of the target point, but only relying on the doctor's hand feeling and experience, even a relatively skilled doctor may make puncture errors during the puncture process. The puncture needle is punctured at the target point of the patient. When the puncture needle enters the patient's body, the doctor cannot accurately grasp the internal situation of the patient's body. Even with the assistance of X-rays, due to the lack of guiding devices, the doctor only During the puncture process with a hand-held puncture needle, it is also easy to deviate from the set path during the puncture, resulting in low accuracy of spinal puncture, requiring multiple puncture needles, which increases the pain of the patient;
