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 poin

Embodiment 1

[0045] Embodiment 1, the auxiliary positioning device for minimally invasive spinal surgery, including a bed platform 1, is characterized in that the bed platform 1 is provided with a horizontal adjustment assembly, the horizontal adjustment assembly is provided with a vertical adjustment assembly, and the vertical adjustment assembly A longitudinal adjustment assembly is arranged on the top, and a support frame 10 is installed on the longitudinal adjustment assembly, and a first auxiliary cylinder 2 is arranged coaxially inside the support frame 10. The vertical ends and horizontal ends of the first auxiliary cylinder 2 are respectively The universal device is axially slidably connected to the sleeve 3 which is rotatably installed on the supporting frame 10. The sleeve 3 is placed outside the supporting frame 10 and connected with a one-way transmission device at one end. The supporting frame 10 is longitudinally The two sides are respectively rotated with ring drive devices, ...

Embodiment 2

[0052] Embodiment 2. On the basis of Embodiment 1, the annular drive device includes a first drive ring 7 and a second drive ring 8 that are coaxially spaced apart and fixedly connected. The inner surface of the first drive ring 7 and the second drive ring A plurality of first gear trains 9 are arranged at staggered intervals on the outer circumference of the two drive rings 8, and the side of the second drive ring 8 facing the support frame 10 is provided with an annular groove 11, and the support frame 10 faces the corresponding second gear. A number of connecting shafts 12 are fixedly arranged on the side wall of the driving ring 8, and several connecting shafts 12 are slidably connected in the annular groove 11, between the first driving ring 7 and the second driving ring 8 at the front end of the supporting frame 10. The first gear 13 that is rotatably mounted on the supporting frame 10 is meshed at both ends, and the upper and lower ends between the first driving ring 7 a...

Embodiment 3

[0057] Embodiment 3, on the basis of Embodiment 1, the one-way transmission device includes a worm wheel 15 sleeved on the end of the sleeve 3 placed outside the supporting frame 10, and the worm wheel 15 is engaged with a rotatably mounted on the supporting frame 10 The worm 16, the first gear 13 and the second gear 14 are respectively connected to the corresponding worm 16 through the pulley set 17.

[0058] When this embodiment is in use, refer to the attached Figure 9 As shown, the sleeve 3 is placed outside the support frame 10 and one end is covered with a built-in worm wheel 15, and the worm wheel 15 is engaged with a worm 16 that is rotatably mounted on the support frame 10. The first gear 13 and the second gear 14 are respectively passed through The pulley set 17 is connected to the corresponding worm 16, and the power is transmitted to the corresponding worm 16 through the pulley set 17 to realize the effect of driving the worm wheel 15 to rotate, and the worm wheel...

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 ...
