Description

A kind of soft tissue excises the intubate of usefulness and adopts the device of this intubate

The present invention relates to a kind of medical surgical apparatus, especially a kind ofly relate to the device that the multiple soft tissue of human body cuts the intubate of usefulness and adopts this intubate.The present invention generally is used to comprise the high delicate procedure at following each related position of surgery, as department of general surgery, Urology Surgery, otorhinolaryngology surgery and cardiovascular surgery such as cosmetic plastic surgery, neurosurgery, orthopedics, orthopaedics, ophthalmology, gynecological, gastrointestinals, interior some other of body needs very careful in soft tissue is removed or prevents hemorrhage position in addition.Though the present invention can be used for multiple operation, following public content relates generally to the used apparatus in cosmetic plastic surgery degrease beauty treatment aspect.

The problem that cosmetic plastic surgery often will run into be about how to the problem of numerous obese patient's degreases beauty treatments, this problem especially looms large in economy flourishing day by day today.A lot of patients attempted multiple non-lipposuction therapy invalid after, lipposuction is expressed in hope.

International comparison at present is popular to be the negative pressure fat absorption method, used apparatus is had the stainless steel tube of a side opening by a far-end, near-end connects suction pipe and connects vacuum extractor and form, the liposuction principle be by distal orifice to fatty tissue scratch unrest and vacuum suction effect, with the fatty tissue sucking-off.But, no matter this apparatus suction nozzle distal orifice diameter and periphery circle are blunt or sharp keen, all unavoidably nervus vasculairs and surrounding tissue are caused damage, hemorrhage more, in the negative pressure fat absorption method, often to transfuse blood to the patient, make that patient's postoperative physical recovery is slower.Reducing the amount of bleeding in the degrease art, is that numerous plastic surgery experts are always in the problem of earnestly exploring.

In recent years, ultrasound wave or high-frequency electronic degrease art also have been applied to clinical, and the broken fat art of ultrasound wave is by inserting intravital special probe emission ultrasound wave, with sucking-off after the liquefaction of fat.CN1116955A " a kind of device that is used for the intubate of fatty tissue extraction therapy and adopts this intubate " patent specification discloses a kind of high-frequency electronic degrease apparatus, this technology is that two arranged side by side parallel needle-like intubate that link to each other with two electrodes of a high frequency electric generating means are respectively inserted in the subcutaneous layer of fat, the heat effect that utilizes the high frequency electric between two intubate with liquefaction of fat after sucking-off.Owing to the reason in apparatus liposuction principle and the design; the measure that this apparatus is not protected surrounding tissue; unavoidably also can cause the hot injury on every side during operation to contiguous fatty tissue and other soft tissue; must make the interior residual fat drop that generates behind the significant quantities of fat cytoclasis that has of body; promptly brought the hidden danger of postoperative fat embolism complication, fat embolism is and fat art severe complications the most.Its emitted energy can not be too high simultaneously, otherwise will strengthen the damage of surrounding tissue thereupon, occurred the low problem of broken fat benefit then, promptly prolonged operating time.Ultrasonic broken fat art also has same problem.So present most of plastic surgeons still adopt general negative pressure fat absorption method.

For can find a kind of liposuction speed fast, go out insufficiency of blood, selectivity, remove fatty tissue with a snap, little to surrounding tissue damage, reduce the generation of fat drop and in vivo residual, reducing the degrease art of postoperative fat embolism complication, the applicant a kind of draws the apparatus of fat by being contained in rotary cutter sheet in the blunt pipe in the patent No. for disclosing in " fatty extractor " patent of " ZL95221334.6 ".On October 25th, 95 " Reference News) " reported the fat absorption method that University of Virginia is same, and report U.S. expert thinks that this technology may substitute common fat absorption method.This technology is before being used as the degrease art, the percutaneous intervertebral disc that has been used to the backbone correcting surgery is removed in the art, this technology is disclosed in CN1120805A " method and apparatus that the wound removal tissue is arranged " patent, although this device is when removing as soft tissue, to reducing the surrounding tissue damage, reduce hemorrhage, aspects such as shortening operating time are useful, but the minimizing of blade cuts efficient is hemorrhage further improving, shortening the operating time aspect also leaves some room for improvement, especially disc tissue is different with the characteristic of fatty tissue, by contrast, the amount that the amount that disc tissue will be removed will be removed than fatty tissue is wanted much less, and does not have central intricate and thick blood vessel and the nerve of resemble fat tissue in it.Not have the degrease art so important so problems such as its operative speed and intraoperative hemorrhage then seem.And the operative speed in the degrease art, the problems such as degree of injury that intraoperative hemorrhage reaches surrounding tissue then are the primary problems that solves.In addition, known soft tissue removal device tends to occur a problem when operation: soft tissue is torn rather than is cut with a snap, when adopting rotary blade cuts, also can make tissue " coiling " or be wrapped in around the cutter, and then fill up cutter and cutter was lost efficacy.

The purpose of this invention is to provide a kind of selectivity, accurately cut fatty tissue fast, improve the cutter cutting efficiency, little to peripheral vessels neural tissue injury, go out insufficiency of blood, the generation of minimally minimizing fat drop and residual amount in vivo cut with the soft tissue that reduces post-operative complication, shortening operating time and use intubate, and the device of this intubate of employing.Though focus of the present invention is that the plastic surgery uses, in excising, other soft tissue that needs the position of accurate operation to reach easily hemorrhage position can adopt similar device.For example the removal cephalophyma in the neurosurgery, tumor etc. are removed the urine surgery that oozes of hyperplastic prostate tissue, and gynecological, ophthalmology, cardiovascular surgery, department of general surgery etc.

For reaching above-mentioned purpose, intubate of the present invention is to adorn movably cutting tool in the trocar sheath by far-end one side opening, simultaneously this trocar sheath or cutting tool are connected with an electrode of a high frequency electric generating means, another electrode of this high frequency electric generating means will be as dispersive electrode, perhaps the intubate trocar sheath is connected with two electrodes of this high frequency electric generating means respectively with cutting tool, to constitute the two poles of the earth of this high frequency electric generating means, be convenient to soft tissue is implemented electroblation.Make the perforate of intubate trocar sheath far-end into several garden shape aperture, both can reduce that the nervus vasculairs tissue is charged into aperture and the chance that is damaged can not reduce operative speed again.

The present invention also at described cannula design the device of corresponding this intubate of employing, but utilize the motor of stepless speed regulation to provide cutting power for cutting tool, in handle, designed normal saline washing passage and negative pressure-pumping passage.

Because the present invention is connected known soft tissue or fatty tissue removal apparatus with the electrode of a high frequency electric generating means, fatty tissue is implemented electroblation, both can improve the cutting efficiency of cutting tool, can in cutting, stop blooding again, can reach substantially in the art and postoperative needn't be transfused blood.Then be invalid aspect hemostasis in the known devices, do not have good hemostasis measure.For example: in the common fat absorption method during as the massive hemorrhage situation, perhaps accelerate transfusion speed and transfusion volume, perhaps supspending operation carries out restarting behind the local pressing type hemostasia again, also may therefore have to end operation, influenced the degrease effect, even can leave over the uneven deformity at degrease position etc., apparatus of the present invention then can carry out " depletion of blood " operation as the electric knife of common surgery, make the doctor have good mood and competent time indiscriminately ad. as one wishes to undergo surgery, reduce by " massive hemorrhage " secondary situation that must be helpless and take place.Have found that the good mental state of doctor is most important to improving surgical effect, especially concerning the plastic surgery belongs to the operation of " art " property like this, seem especially outstanding.

For reducing the damage of fatty tissue medium vessels, nervous tissue, do not reduce operative speed again, make macropore of intubate trocar sheath far-end into several garden shape aperture, garden shape hole shape is more effective than other shape to stoping the nervus vasculairs tissue to enter to be damaged in the intubate.Compare with " CN1116955A " disclosed liposuction device; device of the present invention is to fatty tissue and other soft tissue are provided with under the protective measure situation of " net cover type aperture " on every side; optionally the fatty tissue of charging in the aperture that will remove is carried out clean mechanicalness and electrically excision; as adopting " bipolar system electric knife " form, then littler to the surrounding tissue damage." CN1116955A " described device then is the heat effect that utilizes low-energy high frequency electric, slowly with sucking-off after the liquefaction of fat, has both prolonged operating time, has brought the residual in vivo hidden danger of fat drop again.Adopt the motor of stepless speed regulation to provide cutting power for cutting tool, because of the nervus vasculairs tissue different with the softness characteristics of fatty tissue, so can select a specific cutting frequency, nervus vasculairs etc. are difficult for being cut so that make easier being cut of fatty tissue, and this frequency can be decided by repetition test.Be provided with saline pressure flush transposition in the handle; in saline, add the anaesthetic of dilution, can increase anaesthetic effect, prevent that suction channel from being blocked by the fatty tissue fragment; can more help protecting the nervus vasculairs tissue because of fatty tissue " swelling " back increases blood vessel and partitioning of fat degree again.The device that described intubate becomes with combinations of syringe makes that the soft tissue excision at little position is more convenient, quick.
