Description
Technical field
The solution of the present invention relates to plastic surgery's medical procedures, particularly relates in osseous tissue forming or to change cavity so that use in plastic surgery's process.
Background technology
The surgeon uses minimally invasive surgical techniques to handle multiple medical condition more and more.These technology are usually directed to utilize pipe or sleeve pipe to insert surgery device by the body orifice of nature or by less relatively otch.On the contrary, common surgery operating technology is usually directed to obviously bigger otch, therefore is sometimes referred to as open surgical procedures.Therefore, compare with ordinary skill, minimally invasive surgical techniques provides following advantage: the damage to health tissues minimizes, blood loss minimizes, reduced the danger that complication for example infects and shortened rehabilitation duration.And some minimally invasive surgical techniques can carry out under the local anesthesia situation, anaesthetize in some cases even not, so the surgeon can treat the patient that can not bear the required anesthesia of common ordinary skill.
Surgical method need form cavity usually in soft or hard tissue (comprising bone).Tissue cavities is used for the collection tissue relevant with biopsy or autograft and is used for implantation piece fixing because multiple former thereby formation for example is used to remove pathological tissues.In order to obtain the advantage relevant with less invasive techniques, tissue cavities lessly relatively enters opening and forms by only only producing in destination organization usually.Then, instrument or device insert by this opening, and are used to form obviously greater than the cavity that enters opening.
Utilization forms cavity in tissue a kind of important surgical use is a surgical operation therapy and prevent the fracture relevant with osteoporosis, and this osteoporosis is a kind of disease of metabolism, and feature is that bone amount and intensity reduce.This disease causes fracturing during to medium damage light usually, and may cause fracturing under the normal physiological loading condition in its developmental stage.Osteoporosis is about 1500-2000 ten thousand people of u.s. influence according to estimates, and annual about 1,300,000 fresh fractures are relevant with osteoporosis, and prevailing fracture site is buttocks, wrist and vertebra.
Prophylactic treatment for osteoporosis, damage etc. relates to the next bone that dies down of changing with firmer synthetic bone substitute of use micro-wound surgical operation method.The bone that dies down is at first removed from affected position by surgical operation, thereby forms cavity.Then, this cavity is full of the synthetic bone substitute that can inject, and can solidify.The synthetic bone substitute provides structure to strengthen, and has therefore reduced the danger of affected osteogenesis fracture.But, under the situation that can not adopt the micro-wound surgical operation method, fixedly the bone of osteoporosis-die down is unactual in prevention by this way, because increased sickness rate, blood loss and the complication danger relevant with general surgery.And less invasive techniques will keep the integrity of more bone remaining structure, and this is because its damage to health tissues minimizes.
Enhanced other the more rare situation of structure that may wish bone comprises osteocarcinoma and ischemic necrosis.May relate to by producing tissue cavities for the surgical operation therapy of these situations and to remove pathological tissues, and be full of this cavity, so that provide structure to strengthen affected bone with firmer synthetic bone substitute.
The existing apparatus that is used for forming cavity in soft or sclerous tissues is the assembly of relative complex normally.The U.S. Patent No. 5445639 (" Kuslich ") of authorizing Kuslich etc. discloses reamer between a kind of vertebra that uses when connecting continuous vertebra.The device of Kuslich comprises columnar shaft, and this columnar shaft comprises mechanical mechanism, and this mechanical mechanism makes cutting blade stretch out vertically from this axle, cuts and organizes cavity during with the rotation of box lunch axle.The axle of Kuslich device has relatively large diameter, so that hold the blade extension mechanism, so it may need to produce the relatively large opening that enters, so that will install in the insertion health.Complicated apparatus may be associated with relative higher cost.Axially the cutting instrument that protrudes may limit user's available cutting selection in this processing procedure.
U.S. Patent No. 5928239 (" Mirza ") discloses a kind of percutaneous surgery cavitation device and method, is used at micro-wound surgical operation formative tissue cavity.The Mirza device comprises slender axles and independent cutting tip, and this cutting tip is connected with an end of axle by rotating freely hinge, as shown in fig. 1.The cutting tip of Mirza device around hinge to external rotation, thereby make device can cut the tissue cavities bigger than the diameter of axle.But, the device of Mirza may rely on the axle under 40000 to 80000rpm speed, rotating, this make cutting tip around hinge to external rotation.High rotating speed is like this produced by the high speed surgical drill usually, will be impossible for manual driven.Therefore, such device makes the surgeon accurately to control by artificial rotation when still effectively cutting and organizing.When operation in bone, has the problem that this less relatively hinge component produces structure failure or unclamps under high like this rotating speed.The rotation of the surgical operation drill bit of very high rotating speed (for example from the 40000-80000rpm scope) also may produce too much heat, and this heat may damage the health tissues around the cavity.
The U.S. Patent No. 6066154 (" Reiley ") of authorizing Reiley etc. discloses a kind of device of inflatable, balloon-like, is used for forming cavity at tissue.The Reiley device inserts in the tissue, and inflation then is so that form cavity by compression surrounding tissue (rather than passing through resection organization).But, the Reiley device will not cut and organize, and must cut or otherwise form than areola, so that at first insert the Reiley device in tissue at least usually.Inflatable apparatus also may limit user or the clinician control to cavity shape, and the compression of the osseous tissue of different densities may be very difficult.
Therefore, need a kind of apparatus and method that are used for tissue cavitation, it can be with Wicresoft's mode formative tissue cavity.Also need a kind of cavitation device, it has relatively simple structure, and makes cheaply, and it can manually-operated or operates by the power surgical drill, and makes the user increase the control to the size and dimension of the cavity that forms.
