Embodiment 1

[0039]Embodiment 1, the present invention is a positioning puncture device for spinal surgery, including a support base 1, the support base 1 provides a fixed support base for subsequent structures, and the rear end of the support base 1 is arc-shaped, which is convenient for curling up with the human body It is characterized in that a mounting plate 2 is placed on the support seat 1, and the mounting plate 2 provides a fixed support foundation for the subsequent structure. In this embodiment, a connection of the mounting plate 2 is provided. In this way, the mounting plate 2 is fixedly connected to the support seat 1, the mounting plate 2 is fixedly connected with the limit sleeve 3, and the limit sleeve 3 is connected with the rotating inner ring gear 4 in coaxial rotation. , the limit sleeve 3 is provided with a sliding rail, and the outer circumference of the rotating ring gear 4 is fixedly connected with a rotating rod 47, and the rotating rod 47 is placed in the sliding r...

Embodiment 2

[0043] Embodiment 2. On the basis of Embodiment 1, the patient needs to be sterilized during the puncture process. Therefore, this embodiment provides a device for sterilizing before puncturing. Specifically, the support base 1 The upper end of the rear side is connected with the sliding seat 18 placed on the lower end of the mounting plate 2 and the sliding connection of the mounting plate 2 front and back. The sliding seat 18 is slidingly connected with a disinfection support rod 19 left and right. The side wall of the rod 19 is attached to the inner wall of the sliding seat 18, the upper end of the disinfection support rod 19 is rotatably connected with a disinfection disc 20, and the lower end of the disinfection support rod 19 is rotatably connected with a disinfection driven gear 21, The disinfection driven gear 21 is connected to the disinfection disc 20 through a belt transmission mechanism, the disinfection driven gear 21 is engaged with the disinfection sliding rack 2...

Embodiment 3

[0046] Embodiment 3, on the basis of Embodiment 1, when performing a puncture operation on a patient, when the doctor and the puncture needle or medical equipment are in contact with the patient's skin, the patient will experience a stress response, causing the patient's body to shake, causing the puncture position to be inaccurate. Accurate, so this embodiment provides a specific structure for fixing the human body. Specifically, the support seat 1 is provided with an arc-shaped slide rail 28, and the left and right sides of the arc-shaped slide rail 28 slide An arc-shaped fixing plate is connected, and the arc-shaped fixing plate 29 fixes the human body, and the lower end of the arc-shaped fixing plate 29 is fixedly connected with a first connecting rod 30, and the other end of the first connecting rod 30 rotates A second connecting rod 31 is connected, and the other end of the second connecting rod 31 is provided with a half ring gear 32, and the two half ring gears 32 are r...

Abstract

The invention relates to a positioning puncture device for spinal surgery. The problems that manual puncture is high in instability and inaccurate in position, shaking occurs in the puncture process,a puncture needle cannot be replaced in time, different puncture needles need to be fixed through different devices, the puncture needle cannot be effectively fixed, and the puncture angle of the puncture needle cannot be effectively adjusted are effectively solved. According to the technical scheme, a mounting plate is arranged on a supporting base; a limiting sleeve is fixedly connected into themounting plate; a rotating inner gear ring is coaxially and rotationally connected into the limiting sleeve; the rotating inner gear ring is meshed with three transfer gears rotationally connected into the limiting sleeve; a sliding rack in sliding connection with the limiting sleeve is meshed beside the transfer gears; an arc-shaped clamping plate is fixedly connected to the end, close to the axis of the limiting sleeve, of the sliding rack; and the arc-shaped clamping plate is in contact connection with a limiting sleeve. The positioning puncture device is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning puncture device for spinal surgery. Background technique [0002] Puncture is a commonly used surgical term in medicine. It is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is blood test, blood transfusion, infusion and catheter placement for angiography, etc. Spinal needle puncture in the subarachnoid space of the lumbar spinal cord is an important clinical auxiliary examination method in neurology. It can be used to measure brain pressure, collect cerebral effusion for routine, biochemical and bacteriological examination, tumor cell and enzymatic examination, and provide evidence for the diagnosis of intracranial inflammation, tu...
