Abstract

The invention relates to an intradermal positioning device for lumbar vertebra minimally invasive surgery, which is composed of a positioning device made of X-ray transparent materials and a plurality of kirschner wires. The intradermal part of the positioning device is a sharp head, and the extradermal part of the positioning device is a flat head, a plurality of hollow channels are formed in the positioning device, and kirschner wires used for positioning penetrate the hollowchannels. The kirschner wires are the commonly used kirschner wires in orthopedics surgery. The positioning device has the advantages of being high in positioning accuracy, short in positioning time, less in X-ray time, and low in X-ray radiant quantity that a medical staff and a patient receives, thereby having popularization and application values in minimally invasive spine surgery.

Description

Intradermal positioner in the minimal invasive lumbar surgery art

Technical field

The invention belongs to technical field of medical instruments, particularly relate to Intradermal positioner in a kind of minimal invasive lumbar surgery art.

Background technology

The advantage of minimally invasive spine surgical is that wound is little, goes out insufficiency of blood, and operation does not need extensively to peel off paravertebral muscles, and is minimum to spinal column rear structure destruction, do not affect the stability of spinal column.And accurately before the art Intraoperative position very important for minimally invasive spine surgical, if locate inaccurately, the destruction that just certainly will cause unnecessary spinal column rear structure is damaged thereby increase.It is particularly evident that this shows in minimally invasive spine surgical, such as the implantation of percutaneous cervical arc root screw in the art, previously without any positioner, only have implantation direction, the degree of depth that perspective by repeatedly could clear and definite guide pin.This simple method of sensation that relies on is not accurate enough, often needs the surgical experience that enriches, cooperates repeatedly perspective just can finish again; Both increased operating time, medical personnel and patient repeatedly are exposed under the x-ray radiation.

Summary of the invention

For making the location in the minimally invasive spine surgical art more accurate, shorten operating time, reduce medical personnel's radiation, we have designed and have been specifically designed in the minimal invasive lumbar surgery art Intradermal positioner and are applied to clinical.

Intradermal positioner in a kind of minimal invasive lumbar surgery art that the present invention proposes is comprised of localizer 1 and Kirschner wire 2, and localizer 1 is column structure, and the one end is prong structure, and with inserting the Intradermal part in the Rhizoma Atractylodis Macrocephalae, the other end is tack, is used for the outer part of skin; Localizer 1 interior parallel some the hollow passageway that are distributed with, the Kirschner wire 2 that described hollow passageway is used for Intraoperative position penetrates.

Among the present invention, described localizer 1 adopt x-ray do not develop material (can be macromolecule, timber etc. various on x-ray, do not develop material all can), but manufacture method is mould punching, one-shot forming, or make by hand.

Among the present invention, described Kirschner wire 2 is common Kirschner wire commonly used in the orthopaedics art.

The using method of Intradermal positioner in the minimal invasive lumbar surgery art that the present invention proposes, concrete steps are as follows:

Degree of tilt according to the pedicle locations of body surface marking, patient's fat or thin and vertebral body, at the other skin incision of opening a 0.95-1.05cm of 1-1.5cm place incision of body surface pedicle screw mark position, insert step by step localizer after the expansion, and then in each localizer, squeeze into 3-4 piece of Kirschner wire, carry out the X-ray examination of positive side position, choose suitable Kirschner wire and be used for the puncture location, pull out all the other Kirschner wires; As without suitable Kirschner wire, then stay the Kirschner wire that approaches the most satisfied position, then by the positioner control position, select again suitable Kirschner wire to be used for the location.

The present invention can only reach the in the past effect of tens of perspectives by 1-2 fluoroscopy during operation, has the characteristics of accurate positioning, shortening operating time, minimizing medical personnel's radiation.

The specific embodiment

Further specify the present invention below by embodiment.

Embodiment 1: shown in Fig. 1-2, wherein localizer 1 Intradermal partly is tip, and the skin outside is divided into tack, and other has several hollow passageway, the penetrating of the Kirschner wire 2 of using for Intraoperative position.Such as Fig. 3-shown in Figure 8, (this part describes relatively good in conjunction with figure) is according to the degree of tilt of the pedicle locations of body surface marking, patient's fat or thin and vertebral body, at the other skin incision (such as Fig. 3) that cuts about 1-1.5cm about a 1cm of opening of body surface pedicle screw mark position, insert step by step Intradermal positioner (Fig. 4) after the expansion, and then in each Intradermal positioner, squeeze into 3-4 piece of Kirschner wire, carry out the X-ray examination of positive side position, choose suitable Kirschner wire and be used for puncture location (Fig. 5), pull out all the other Kirschner wires (Fig. 6).As all there not being suitable Kirschner wire, then stay the Kirschner wire (Fig. 7) that approaches the most satisfied position,, then adjust the position by the Intradermal positioner and select again suitable Kirschner wire to be used for location (Fig. 8).

Workflow of the present invention is as follows:

A: insert step by step the Intradermal positioner after the expansion;

B: squeeze into 3-4 piece of Kirschner wire in each Intradermal positioner, carry out the X-ray examination of positive side position;

C: choose the Kirschner wire that is positioned at correct position and be used for the puncture location;

D: red-label is suitable Kirschner wire among the figure;

E: all do not have suitable Kirschner wire, then stay the Kirschner wire that approaches the most satisfied position;

F: adjust the position by the Intradermal positioner and select again suitable Kirschner wire to be used for the location.

Embodiment 2: the inventor did relevant clinical research to localizer.121 routine prolapse of lumbar intervertebral disc are merged lumbar instability patient and patients with thoracolumbar fracture, use the contrast of traditional method and novel method, be 15.12 ± 4.69min the positioning time that discovery use traditional method is implanted in single sections pathological changes operation in patients before two piece percutaneous cervical arc root screws, and the location number of times is respectively 6.47 times.Be 5.51 ± 1.32min and use novel method positioning time of localizer, the location number of times is 2.45 times.
