Abstract
The utility model discloses a magnet navigated device used to place a conduit into an extradural position, and consists of a magnetic body for navigation, a magnetic conduit and a fixer. The device is capable of delivering the magnetic conduit to an extradural pathologic part, injecting drugs for treatment, and alleviate the extradural adhesion caused by a spinal operation. The utility model has the benefits of convenient operation, accuracy, minimal injury, safe use and fulfillment of the sterilization requirement by using the magnetic force for navigation and fixing.
Description
Technical field
This utility model relates to a kind of magnetic navigation epidural target to the device of putting pipe, can accurately conduit be inserted and cause the epidural space certain location.
Background technology
Conduit is presented to peridural specific part and continues the effective means that injection is treatment neck, waist source property pain, after the epidural puncture success, usually epidural catheter is bent to certain shape, by puncture needle conduit is delivered to assigned address again, but in fact to accomplish accurately conduit to be delivered to very difficulty of diseased region, often need to put repeatedly pipe, usually cause tissue injury, hemorrhage etc.; Common epidural catheter does not develop under the X line, can not accurately judge its position; Short in the epidural space traveling, be difficult for sending to far-end; Passing the skin place easily gives a discount; And conduit also is difficult to fixing.
Consideration in view of the above problems, the purpose of this utility model provide a kind of magnetic navigation epidural target to the device of putting pipe, and its technical characterstic and soluble problem are as follows:
The conduit softness, certain resiliency is arranged, the not nerve of easy damaged epidural space, blood vessel.
2. conduit can develop under the x line, therefore can clearly locate.
3. employing magnetic navigation, the orientable pipe of putting.Experiment to Canis familiaris L. shows, put epidural anterior diastema (position of intervertebral disk hernia) easily, the once holding tube success rate reaches 100%, carries out the treatment of cervical pain, lumbar and back pain and intervertebral disk hernia by injection anti-inflammatory analgesic, collagenase (dissolving intervertebral disc).And common epidural catheter is difficult to reach the epidural anterior diastema.
4. the anterograde of conduit is good, but can be more than epidural space traveling 30cm (zoopery confirms), by (epidural space of this several places correspondence is wide at neck 7 breasts 1 and waist 3-4 or waist 4-5, put pipe easily, put pipe and safely) and can reach the peridural any gap of vertebra, continue the infusion local anaesthetics by conduit, can carry out the epidural anesthesia of corresponding operation, excise, open the anesthesia of the very difficult realization of the external pipes of common dura mater such as breast lobectomy of lungs and esophagus operation as thyroid operation, the mammary gland operation of chest, gallbladder, the stomach of cervical region.And can significantly reduce the consumption of GENERAL ANESTHETICS with the general anesthesia use in conjunction, and reduce surgery cost, can carry out the patient-controlled continuous analgesia of effective postoperative epidural (analgesic effect is definite than the patient-controlled continuous analgesia of vein, and side reaction is few) again.Common epidural catheter is flexible to be difficult in the epidural space traveling, is difficult to realize the anesthesia of above-mentioned operation.
5. pass through special holder, fixation, conduit is difficult for displacement, can carry out the external pipe analgesia therapy of long-term dura mater, as the analgesia therapy of ache in late cancer.
6. conduit is difficult for giving a discount.
Summary of the invention
The purpose of this utility model provides a kind of magnetic navigation epidural target to the device of putting pipe, and this device is made up of with magnet, magnetic catheters, holder navigation.It is characterized in that navigation is a permanent magnet with magnet, it is shaped as vertebral cylinder, can guide magnetic catheters.Magnetic catheters is made up of softish skin, intermediary spring and steel wire inner core, but the outside magnetic field effect is moved down.Holder is a wing, in order to the fixed magnetic conduit.
It is characterized in that the softish skin of magnetic catheters has magnetic, its intermediary spring has magnetic and maybe can be magnetized, and front end has aperture, can be used for carrying medicine by aperture.
It is characterized in that holder is made up of inner core, skin fixed-wing.The holder inner core is moulded magnetic for the hollow that is complementary with the magnetic catheters external diameter, can magnetic catheters absorption is fixing, and the skin fixed-wing is stuck on the described holder inner core, and both sides respectively have a hole to be used for fixing by suture and skin.
The navigation power and the bed knife that it is characterized in that magnetic catheters are the magnetic force that magnet is used in external navigation.
The beneficial effects of the utility model are to adopt magnetic force as navigation power and bed knife, and are easy to operate, accurate, damage is little, safe in utilization, meets aseptic requirement.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a vertical section of the present utility model structural map.
1 magnet, 2 conduit perforates, 3 catheter outers, 4 conduit intermediate magnetic springs, 5 steel wire inner cores, 6 mould the magnetic inner core with the holder of anastomosis catheter, 7 holders are moulded magnetic inner core and the identical groove of skin fixed-wing, and 8 skin fixed-wings are moulded the projection that the magnetic inner core coincide with holder on the 9 skin fixed-wings, the fixing aperture of using that 10 skin fixed-wings pass for suture, 11 steel wire inner core handles.
The specific embodiment
After the success of cervical region or waist epidural puncture, as carry out the cervical region epidural and place conduit magnet 1 is placed the throat; Before placing conduit and then magnet 1 is placed abdomen as the waist epidural.Extract steel wire inner core 5 by steel wire inner core handle 11, slowly send into conduit through anesthesia spinal needle, come guide catheter by the position of adjusting magnet 1, determine the position of conduit by X line or CT image, after treating conduit delivered to the precalculated position, at distance epidural puncture point 15-20cm place conduit is drawn outside the skin, conduit and holder are moulded magnetic inner core 6 to join, the projection 9 that skin fixed-wing 8 is moulded on the magnetic inner core 6 by groove 7 and holder fastens again, with suture by fixing on the skin fixed-wing with aperture 10 with skin fixed-wing 8 and skin closure, by conduit perforate 2 medicine is injected into the precalculated position and treats, make the conduit swing can carry out the vertebra postoperative by adjustment magnet 1 position in addition and cause loosening of epidural adhesion.
