Description

Spinal cord epidural anesthesia therapeutic instrument in the canalis spinalis

This utility model relates to surgical anesthesia and pain therapy instrument, is spinal cord epidural anesthesia therapeutic instrument in a kind of canalis spinalis.

Spinal cord epidural anesthesia art in the existing canalis spinalis guides single chamber anesthetic tube with puncture needle, inserts spinal cord epidural in the canalis spinalis, injects anaesthetic by single chamber and anaesthetizes, for example abdominal operation anesthesia.Also can inject curative drug and be used for the treatment of position painful diseases such as neck shoulder, extremity, back, abdomen perineum, for example sciatica.But, this single lumen catheter anaesthetic apparatus, it is liquor-saturated or twilight-sleep that cerebral cortex and visceral nerve are only had a not general anesthesia.When anesthetics dosage was big, its toxicity can cause circulatory and respiratory and suppress, even threat to life, and mortality rate is up to 1/2000 according to reports.When this apparatus is used for pain therapy, invalid to head, jaw face ache disease, trigeminal neuralgia for example.

Existing periphery acupuncture of a point (electricity irritation) anesthesia (pain relieving) art is to use the acupuncture-moxibustion principle with acupuncture needle or electricity irritation periphery acupuncture point, is used for anesthesia or pain therapy.Because the periphery acupuncture point is far away apart from the central nervous system, curative effect is relatively poor sometimes, and the patient electrode sense is uncomfortable strongly.

The purpose of this utility model provides spinal cord epidural anesthesia therapeutic instrument in a kind of canalis spinalis, and it can carry out drug anesthesia and treatment, can carry out electricity irritation anesthesia and treatment again.

For achieving the above object, spinal cord epidural anesthesia therapeutic instrument in the canalis spinalis of the present utility model, by casing, the knob on the machine shell panel, on and off switch and display lamp, pulse oscillator circuit device in the casing, and conduit is formed.Be characterized in the conduit transverse section for circular, fraction is hollow, and major part is an entity.In entity, be embedded with the silvery or the steel wire of two surface insulations.Lead rear end protruded tube is outer to be connected with negative pole with the casing internal circuit is anodal.The lead front end is fixed on the conduit outer wall, and the fixing point of its electrode line and negative line is at a distance of 2-5 centimetre.Conduit can be manufactured with plastics or silica gel.

The fixed form of lead front end is back hook-type, and thrust in the conduit entity tip, and curve part is exposed to outside the conduit, its surperficial naked lacquer.

This utility model is compared with prior art, owing to be provided with hollow and entity two parts in the conduit, utilizes hollow carry out drug anesthesia and treatment, utilizes interior two leads of entity to carry out electricity irritation anesthesia and treatment.The advantage associating of single lumen catheter and two kinds of apparatuses of acupuncture and the achievement of learning from other's strong points to offset one's weaknesses have been embodied.Therefore, can reduce drug dose, alleviate drug toxicity harm.Acupuncture of a point is compared with periphery, owing to be that its anesthesia of maincenter spinal cavity electricity irritation and therapeutic effect are better.When disappearing, anaesthetic can carry out the electricity irritation pain relieving.Can be used for coma patient, the electricity irritation of general anesthesia patient maincenter wakens and withdrawal and drug addiction treatment.

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1 is the cutaway view of the used conduit of spinal cord epidural anesthesia therapeutic instrument in this utility model canalis spinalis.

Fig. 2 is along A-A line cutaway view among Fig. 1.

Fig. 3 is the front end of lead shown in a Fig. 1 fixed form front view.

Critical component of the present utility model is conduit and inner lead thereof.As shown in Figure 1, conduit 1 has two parts, i.e. hollow parts 2 and entity part 3.As shown in Figure 2, the transverse section of conduit 1 is circular, and hollow cavity has the function of single lumen catheter, can inject medicine and anaesthetize and treat.Entity part is embedded with the silvery or the steel wire 4 of two surface insulations.Lead rear end protruded tube outer with the therapeutic instrument casing on circuit anode be connected with negative pole, the lead front end is fixed on the conduit outer wall, the fixing point of its electrode line and negative line, forms electric loop at spinal cavity and produces electricity irritation to guarantee not to be short-circuited phenomenon at a distance of 2-5 centimetre.

As shown in Figure 3, the fixed form of lead front end is back hook-type, and thrust in the conduit entity tip 5, and curve part 6 is exposed to outside the conduit, its surperficial naked lacquer.Return hook-type and can combine the generation resistance, avoid lead in conduit, to be moved with the conduit entity.Curve part is on-insulated to be made electric current can conduct to spinal cavity to form electric loop.

The pulse oscillator circuit device can be chosen commercially available finished product in knob on casing, the machine shell panel, on and off switch and display lamp and the casing.The electrical stunning device made of Shanghai China friendship medical apparatus factory for example, its voltage equal or do 40 volts for a short time, and its frequency adjustable scope is that the 2-40 cycle per second is adjustable continuously.

Using method of the present utility model.With gastrectomy and cholecystectomy is example.

(1) patient's anesthesia: (1) conventional rachicentesis, insert double channel catheter of the present utility model.(2) anesthetis of partly measuring by cavity injection routine dose carries out drug anesthesia.(3) opening power makes voltage and frequency knob be in low gear position, and electricity irritation arrives spinal cord rapidly.(4) adjust voltage and frequency according to the patient reaction and carry out electricity irritation anesthesia.(5) operation finishes back drug anesthesia effect disappearance, and the patient feels pain, continues to keep electricity irritation, produces analgesic effect.

(2) sciatica there is specially good effect.The onset that heals with medicine in the past is slow, and the painful time of patient is long.Adopt this therapeutic instrument, insert double channel catheter through puncture, cavity injects medicine, and the entity electrode carries out the electricity irritation pain relieving, this " combination of Chinese and Western medicine " treatment that is concrete.Owing to be the maincenter electricity irritation, curative effect is fine.Because pin () stimulates adjustable complete machine body balance, stimulate body to produce disease-resistance substance, the enhance immunity ability produces pain relieving material endorphins, makes the very fast rehabilitation of sciatica.

It is respond well to use this double channel catheter treatment 29 examples.The equal no pain of postoperative patient in the art, the anesthetis consumption reduces 1/3rd.
