Description

Spinal surgery puncture locator

Technical Field

The invention relates to a medical auxiliary instrument, in particular to a spinal surgery puncture locator for spinal puncture.

Background

Spinal puncture, namely lumbar puncture, is a common clinical diagnosis and treatment operation and can be used for diagnosing various inflammatory diseases of the central nervous system, vascular diseases, suspected intracranial space occupying lesion, spinal angiography and the like.

The general operation method of spinal puncture is that the patient lies on one's side in bed, and both hands hold the knees (even the knees raise towards the upper body), makes the lumbar kyphosis, the intervertebral space widens, then after the operation personnel disinfect, anaesthetize, puncture in the awl space between 3 rd ~4 th or between 4 th ~5 th.

Therefore, in order to increase the success of the puncture, the lumbar vertebra is enabled to be convex backwards, and the increase of the intervertebral space is particularly important, so that before the puncture, doctors need to know that the patient bends over to carry out the knee holding action of both hands, some patient actions are not standard, and need to repeat many times, which greatly delays the operation efficiency, and more importantly, the patient needs to keep the posture until the operation is finished, namely the patient needs to keep the force application posture for a long time, which is difficult for children without self-control ability, and if the patient cannot keep the posture in the operation, other actions can cause the puncture needle to shift, which can result in the puncture failure.

Disclosure of Invention

The invention aims to provide a spinal surgery puncture locator for keeping the lumbar kyphosis posture of a patient.

In order to solve the technical problems, the technical scheme of the spinal surgery puncture locator is as follows:

the utility model provides a spinal surgery puncture locator, includes the puncture seat, and the puncture seat includes the seat landing leg and sets up in the seat support of seat landing leg upper end, is provided with bedplate and the back of arranging around on the seat support, and the back includes the movable festival that at least three-section set up in order along upper and lower direction, and each movable festival all includes that the axis is along the installation cover and the pivot of rotating assembly in the installation cover that the left and right directions extends, and the movable festival still including install in be used for the drive on the installation cover pivot pivoted servo motor, movable festival still including being fixed in the epaxial back board of commentaries on classics, two adjacent movable festival are upside movable festival and downside movable festival respectively in the upper and lower direction of definition, and the installation cover of upside movable festival is fixed in the back board upper end of downside movable festival, all is provided with the about band that is used for patient's upper part of the body to link to each back board, offers the puncture that is used for dodging the puncture operation on the corresponding back board and dodges the hole.

The invention has the beneficial effects that: when the invention is used, a patient sits on the seat board, the back leans against the backrest, the corresponding part of the upper body of the patient is bound on the corresponding backrest board through the restraint strap, each servo motor can drive the corresponding rotating shaft to rotate, so that the lumbar kyphosis of the patient is in an ideal puncture posture, a doctor can perform puncture operation on the patient through the puncture avoidance hole, the patient is restrained by the restraint strap, the lumbar kyphosis of the patient is driven by each movable joint to be automatically kyphosis, the whole process does not need the force of the patient, the kyphosis posture of the patient can be effectively maintained, the force intensity of the patient in the operation can be reduced, and the problem of puncture failure caused by no self-control force disorder in the patient operation can be avoided.

Furthermore, the restraint strap comprises a left side strap body and a right side strap body which are arranged in a split mode, one end of the left side strap body is fixedly connected with the left end of the backrest plate, one end of the right side strap body is fixedly connected with the right end of the backrest plate, and the left side strap body and the right side strap body are connected through the thread gluing strap.

Furthermore, a lifting support driven by a backrest lifting mechanism is arranged at the rear end of the seat support, and a mounting sleeve of the movable joint at the lowest position is fixed on the lifting support.

Furthermore, the backrest lifting mechanism comprises a driving screw rod and a lifting screw nut, wherein the rotating axis of the driving screw rod extends along the vertical direction, the lifting screw nut is matched with the driving screw rod, and the backrest lifting mechanism further comprises a screw rod driving motor which is in transmission connection with the driving screw rod.
