Abstract
The invention relates to a locating assist device for a spinal operation, and belongs to the technical field of medical apparatuses.The device is composed of locators and connectors; each locator is shaped like a hollow and sealed cylinder, and the two ends of the cylinder wall of each locator are each provided with a ring-shaped groove; each connector is shaped like a strip-shaped plate, the two ends of the connector are each provided with a clamping notch, the clamping notches are matched with the ring-shaped grooves, and a cavity of each locator is filled with a contrast agent.When the device is used, the clamping notches of the connectors are clamped in the ring-shaped grooves of the locators and are arranged on the back of a patient in the mode of being perpendicular to the spine, and the position and serial number of the locators are traced on the skin with a marking pen.When an imageological examination is conducted, the locators can directly conduct developing on an imaging result, and by means of the relative position relations between the numbered locators and lesions, the operation can be conducted directly according to the result.According to the locating assist device for the spinal operation, the lesion position can be located accurately, the medical risk of the patient is reduced, and unnecessary radiation exposure for the patients and medical workers is reduced.
Description
Technical field
The invention belongs to medical apparatus and instruments technology for making field, relate to a kind of surgery positioning device.
Background technology
At present, the mode of spinal lesion location is still more original, adopts X-ray, CT, MRI to carry out iconography, and first determine particular vertebra according to features such as spinal bone shape, rib, head end, tail ends, such as neck 1-2, breast 1, breast 12, waist 5 vertebral body such as grade, then vertebral body counts and determines lesion locations one by one.According to vertebral body position in operation, by hand spinal column is counted, it is determined that lesion locations.
But this mode there is problems in that
1, there is the possibility of error in manual count, and patient's height is fat or thin, deformation of spinal column etc. can result in counting and make mistakes, and deviates lesion locations；
2, operation use X-ray machine etc. carry out bone location, need to insert many metal needles on above-mentioned significant vertebral body spinous process, then repeated multiple times take pictures, finally determine position, pathological changes there is the situation of invasive, may result in complication and occur, if can not be developed under X-ray simultaneously, then still need to manually combine bone positioning result with other imaging examinations, equally exist situation described in the problems referred to above 1；X-ray, CT etc. check there is radiation injury situation simultaneously, repeatedly have an X-rayed, scan, increase the possibility that patient radiation's property complication occurs, the medical personnel of surrounding can be produced unnecessary roentgenization simultaneously；
3, owing to MRI examination scope limits to, and to sclerotin poor display, particularly in thoracic vertebra part, there is the possibility that cannot accurately determine pathological changes place vertebral body；
4, pathological changes be likely to only MRI check in development (such as tumor etc.), but location need x-ray or CT carry out bone scanning determine, the two in conjunction with time deviation easily occurs, cause positioning unsuccessfully.
5, because of above-mentioned reason, before operation starts, patient need to verify and confirm repeatedly, wastes the plenty of time, extends corrective surgery, anesthesia duration, increases patient medical risk, increases patient treatment expense.Even because positioning unsuccessfully or slipping up, cause patient's iatrogenic injury, cause doctor-patient dispute.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of positioning auxiliary device for spinal operation such that it is able to when carrying out imaging examination before corrective surgery, auxiliary is accurately positioned lesion locations.
Apparatus of the present invention are made up of localizer and adapter, localizer is the cylinder-like body of hollow seal, including barrel and end cap, barrel both sides have a ring annular groove, adapter is bar shaped plates, its two ends have a card to slit respectively, and card slits and coordinates with cannelure, are full of contrast agent in the cavity of localizer.During use, slitting in the cannelure being stuck in localizer by the card of adapter, form ladder shape, vertical spinal column is placed on patient back, uses medical adhesive tape to be firmly pasted on skin of back, uses marking pen locator position, numbering to be traced on skin simultaneously.While imaging examination, localizer can directly develop on imaging results, and the relative position relation according to numbering localizer and pathological changes is directly operated on according to this result in operation, reached to be accurately positioned the purpose of pathological changes.
The thickness of adapter is the half of annular groove width so that localizer and adapter connect more compact.
Localizer can also be oval cylindrical body in fact; it it is all wire after development; but processing and use are convenient all without cylinder-like body; and cylinder-like body is it can be appreciated that comprise oval cylindrical body; so while a proposition localizer is the cylinder-like body of hollow seal in summary of the invention, oval cylindrical body also should in scope of patent protection.
Adapter can adopt resilient plastics to make.
Developing agent therein selects different implants at different imaging examinations, and MRI selects: sterilizing edible oil and fat filled by A type, and Type B fills medical saline, and x-ray, CT select: Medical barium meal contrast agent filled by C type.
Apparatus of the present invention can be accurately positioned lesion locations, saves non-essential operation and anesthesia duration, reduces the probability that malpraxis occurs, reduce patient medical risk, reduce patient and the unnecessary ray of medical personnel exposes, reduce corrective surgery expense, Economy type medicine cost.

Detailed description of the invention
Apparatus of the present invention are made up of localizer 1 and adapter 2, localizer 1 is the cylinder-like body of hollow seal, including barrel 3 and end cap 4, barrel 3 both sides have a ring annular groove 5, adapter 2 is bar shaped plates, and its two ends have a card to slit 6 respectively, and card open-minded 6 coordinates with cannelure 5, being full of contrast agent in the cavity of localizer 1, the thickness of adapter 2 is the half of cannelure 5 width.Wherein localizer 1 length is 40 millimeters, and diameter is 5 millimeters, and cannelure 5 width is 2.5 millimeters, and the distance between the cannelure of both sides is 20 millimeters.
