Problems solved by technology

[0003] The existing surgical area in the deep part of the spine is extremely small, surrounded by many important nerves, blood vessels, and internal organs, and sometimes it is necessary to avoid the hard bone tissue, and the doctor must strictly follow the surgical needle approach designed before surgery In order to safely and smoothly reach the ideal surgical area and avoid serious surgical complications or sequelae, since there are many nerves, blood vessels and bone tissues in the spine, once the needle position is slightly deviated, it will cause unpredictable consequences , so the adjustment of the positioner is extremely important. The existing positioner adjustments rely on computer operation, and people cannot observe the adjustment distance on the positioner body, and most of the existing positioner adjustments can only be adjusted through the computer to adjust the puncture needle. It is difficult to adjust the angle of the whole body accurately, so a spinal surgery puncture positioner is proposed to solve the above problems

Embodiment Construction

[0023] The embodiment of the present invention discloses a spinal surgery puncture positioner, such as Figure 1-5 As shown, it includes a fixed sleeve 1, and one end of the inner cavity of the fixed sleeve 1 is provided with a first rotating groove, the first rotating groove is internally connected with a first rotating shaft 2, and both ends of the first rotating shaft 2 are fixedly connected with a first cone. For the gear 3, the end of the fixed sleeve 1 away from the first rotation groove is provided with a first through hole, the end of the fixed sleeve 1 close to the first through hole is fixedly connected with a motor, the first rotating shaft 2 is fixedly connected with the output end of the motor through the first through hole, Both ends of the top of the fixed sleeve 1 are provided with a second through hole, and the first threaded rod 4 is movably sleeved inside the second through hole. The meshing connection with the second bevel gear 5 drives the first threaded r...

Abstract

The invention discloses a puncture locator for spine surgery, and relates to the technical field of medical apparatus and instruments. The puncture locator for the spine surgery comprises a fixing sleeve, wherein one end of the inner cavity of the fixing sleeve is provided with a first rotation groove; a first rotation shaft is arranged in the first rotation groove; two ends of the outer side of the first rotation shaft are independently provided with a first bevel gear; one end of the fixing sleeve is provided with a first through hole; one end, which is near the first through hole, of the fixing sleeve is provided with a motor; the first rotation shaft is fixedly connected with the output shaft of the motor through the first through hole; two ends of the top of the fixing sleeve are independently provided with a second through hole; a first threaded rod is arranged in each second through hole; and the bottom of each first threaded rod is provided with a second bevel gear. By use of the puncture locator for the spine surgery, the problem that a slight deviation of a needle inserting position causes an inestimable result can be effectively solved, and the problems that most existing locators only can regulate the angle of a puncture needle through a computer and each angle of the whole can not be accurately regulated can be solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a spinal surgery puncture positioner. Background technique [0002] The spinal puncture positioner is used for the puncture positioning of a certain target point in the deep spine in the body, specifically for the puncture positioning of various parts of the spine such as intervertebral foramen, intervertebral discs, articular processes, and pedicles. [0003] The existing surgical area in the deep part of the spine is extremely small, surrounded by many important nerves, blood vessels, and internal organs, and sometimes it is necessary to avoid the hard bone tissue, and the doctor must strictly follow the surgical needle approach designed before surgery In order to safely and smoothly reach the ideal surgical area and avoid serious surgical complications or sequelae, since there are many nerves, blood vessels and bone tissues in the spine, once the needle position is...
