A conventional device for a reforming operation usually has a saw or a file, and a hand tool designed to be used in combination with a saw or a file. The head performs a reforming operation with this device or grinds the bone with a lithium knife. A typical form is to use a saw to cut bones. It is necessary to cut a large number of bone fragments one time, thus creating a problem of quasi-degree. It is basically necessary to ensure the field of view so that the cutting angle can be correctly determined, the bone fragments can be easily discharged, and the cutting area can be easily accessed. Because of the need for a large incision to ensure visual field, there are various problems, including severe swelling and bleeding, delaying healing, damaging blood vessels and damage, and God. In addition, there are other problems in that the saw with the cutting bone may cause serious damage to the soft tissue around the bone when the bone is cut. The child saw is mainly used to narrow a large tibia, for example. In this example, 1250008, the body of the humeral arch or the anterior segment of the tibia is completely resected, and the posterior portion of the humeral arch or the posterior segment of the tibia is not completely removed by the saw, and then the humeral body is compressed to achieve the back. Incomplete fracture. This type of surgery is complicated and dangerous. ” Because the existing power mine may not be able to operate efficiently in a small space, or because the wide shape of the power mine may touch the tissue and damage the surrounding tissue, in order to cut the front area & 4cm, in order to completely reveal the tibia. For the non-complete cutting of the ji~J lei bone arch, the anterior incision is performed to reveal the humeral arch. The humeral arch is followed by a bone impact or a The amount of cut can only be adjusted by the operator's feeling. In this operation, the incision in the mouth may damage the nerve and cause bleeding, and the incision in front of the ear is dangerous because it may It will be a time-consuming injury to the facial nerve or blood*, and the incision or wound suture is time-consuming. As a result, this surgical operation has an inevitable general anesthesia and continued swelling after surgery. Although the cutting of the bone is through the face The smallest incision is used for the advantage. However, in order to ensure sufficient space for the cutting mechanism and the wrong insertion space, the slit must be opened to a certain extent to allow — : can be inserted through the incision. There is no way to reduce the size of the incision. When the tibial cutting is performed through a small opening or incision, a bone is also used, in which the tip end of one of the bone plugs often damages the mucosa. Some people have tried to use a linear reciprocating recorder, but it is rarely used because it has to be hard to expose the surface of the 1250008 bone. ^In the surgery to reduce the contour of the face, unlike the use of the saw, the file T is used, grinding Bone. This surgical procedure has the characteristics of a grinding car in other surgical operations, especially for a short period of time, and the meat or moon granules can be expelled together with the bone. It must be operated within & time to minimize bleeding and swelling. This is because the overall thickness of a wide flat bone must be reduced, and this surgical procedure requires a wide effective cutting surface for contact with the bone. j. In the use of traditional trowels, bone chips can accumulate, block or press between the molars of the file, and % cannot perform continuous cutting. Therefore, for example, Or the pneumatic squeegee's molars need to be cleaned every few minutes. This method uses a traditional trowel for plastic surgery and needs to quickly grind a large number of bones. f Grinding a large number of bones S members are not using power or pneumatic knives. Another reason 疋 'The heat on the cutting surface will accelerate the accumulation of bone chips. Manual or manual 锉P will make ', no heat!' But due to the low working speed, it is rarely used. Traditional grinding a large number of methods. Grinding large plastic surgery membranes or muscles with maximum outer diameter and unable to force or pneumatic tools can not be inserted into a small hole to connect the humeral head. There have been problems in solving the problem of removing a small amount of bones, but these methods are not suitable for In facial plastic surgery, there is almost no way to perform facial treatment. In addition, facial plastic surgery requires a considerable amount of bone particles and bone particles to be discharged together, and compared to the insert, The cutting surface is quite wide and long. However, the previously proposed knot solves these problems' and has therefore not been applied to facial plastic surgery 1250008. Since the face bone requires a maximum cutting surface of 40 mm or more, the tool for facial plastic surgery has a position and an angle of bone removal and a bone removal position of the previously mentioned bone removal tool and The angles are not the same. Even small areas of contact with the file can remove relatively small protrusions and cartilage. However, the #刀 needs to be in contact with the bones of a large area to grind all the surfaces of the face bone into the desired shape. Therefore, it is necessary to make the lithium teeth of the boring tool to make a long sound of at least 30 mm, so as to insert it into the heart to evenly grind the cutting surface. A mechanism for re-moving, a cutting member, a cutting member that cuts the suction opening of the suction opening, and a method for solving such problems is disclosed in U.S. Patent No. 6,368,324. In this document, a hand-held appliance combination for a power surgery is proposed, which has a power surgical handpiece coupled to an adapter. The adapter has - for converting rotational motion into linearity, for example A coupling opening is formed with a suction opening, and a coupling member is formed so that the cutting member formed on one end of an elongated shaft can be inserted into the ancient _ field recognition + exit 丨For cutting, for example, the bone of the cheekbones. ~ This method has the advantage of cutting the saw compared to the bone because it cuts a bone and cuts the bone fragments through the suction hole by cutting the skin a minimum amount. However, @'salt solution is not supplied to the cutting surface, so if the cutting is performed for example, it is the bones of the bones and the rhyme of the Jinshidan, and the heat from the cut surface cannot be ruled out. in. The suction hole is not made to support continuous cutting, and needs to be cleaned frequently 'because the dental caries 1250008 in the surgical operation are blocked. The bone 4 is not being used. This method can be used in the two cases of nasal angioplasty. Reconstruction of the whole or eyelids' because it does not need to cut a large number of bones two: and the ιΜ heavy method still has shortcomings, which cannot be effectively applied to most of the θ-foldings, such as the angular horns made with traditional minerals. The reforming or sputum is used to remove the bone fragments for transplantation. For the reforming operation, for example, the reformation of the horns and the reduction of the humerus = the bones are cut or ground, and the frictional heat is generated due to the prolonged cutting. This causes different crises, such as burns of soft tissues and And weaving deformation. At the same time, bone fragments may harden during cutting, and the head: = inserts the cutting teeth without being discharged to the outside. Then the hardened bone can produce friction, which in turn can seriously reduce the cutting efficiency. Although the bone fragments were taken out for the establishment of bone tissue, the bones were broken, but the heads of the house were taken up by the use of the moon. There are also during the (four) component (four) period, stimulation <

The shortcomings of bad skin and soft tissue. Seven pairs of A rows are inconvenient, for example, through a small and deep incision to the surrounding part: two = it: with the advance; during the operation and operation, can not protect the tissue, and then the cutting part of the square Friction may break, making this method inconvenient to be applied to plastic surgery. The I set I: a 5:54 °, 693 patent proposed a surgical device for shifting two: = lithium knife and double tube. However, this method does not apply to the cutting part:: ut仃 contour surgery' This is because the problem of the sheet cannot be cooled. This method can achieve a wide area of the suction tube by using a cutting portion: or " a shank of a knife like a suction 1250008 into the tube, even through a small incision, and then protecting the surrounding tissue with a protective tube. However, because the suction hole does not pass through the cutting face, the device is almost incapable of producing large or large amounts of tissue: inhalation or treatment of tissue particles under the grain, and therefore not suitable for plastic surgery. Wu Guoguo No. 5,643,3G4 And the 5th, 4G3, 276 patent discloses a vibrating file for removing bone or cartilage. The file has a sturdy structure for the supply and inhalation of the double solution of the salt solution through an elongated slit between the trowels. This method can advantageously prevent the hardening of bone chips and the destruction of surrounding tissues due to frictional heat. However, this method is almost incapable of avoiding bone chips - blocking between the teeth of the lithium knife. Since the cutting portion of the shaft shank is a liquid supply tube and the outer tube is a suction tube, it must increase the diameter of the outer tube and has a disadvantage. In addition, since the ground bones after grinding move along the direction of penetration of the cutting edge of the silicon cutting blade, there is no elongated slit between the teeth of the cutting blade passing through the cutting face, which is impossible to prevent the accumulation of bone chips. Even if the salt solution is discharged through the orifice, the pressure is obviously less than the discharge pressure of the bone chips, and thus the blockage = the small hole that is blocked by the plug will also block the discharge through the small holes: the salt solution, and then reduce the file according to a vicious cycle. The number of molars 趟^= is only suitable for removing a baby with two or three lithium teeth. Knife and I / combined liquid ί, the small amount of bone fragments in the hole of the life, soil, gentry 7 However, this structure is used as in the surgical plastic surgery to remove or remove a large block at the same time Bone tissue or Liyue Μ ^ ^ ^ ^ ^ to the surgery. This structure is achieved by a long cutting portion having a plurality of blades or teeth. 1250008 In addition, this type of structure is also a "1", which is a very important principle. The principle is to pierce a relatively large hole through the cutting surface, and reciprocate with a file to form a corresponding direction of bone flow. And the suction pipe in the direction of pressure. In this case, the largest cutting face can hardly be obtained from the smallest outer diameter. As a result, until now, this structure has not been applied to facial plastic surgery. Such a file is known to be used in endoscopic surgery, for example, on the knee cartilage or vertebrae to remove a small amount of contact with the rake lithium tooth. The outer tube is aspirated and protrudes from a small amount of small part 'but not used in facial plastic surgery, which is actively cut on the face—for example, the width of the humeral arch or the humerus, and the hard surface . The National No. 4 Wind M patent discloses a hand grinder or trowel that has a temple of a hole through a cutting surface. Because this method is made "in general, it does not take into account the heat capacity is not effective enough, it only:; = should." However, these perforated functions are used for the inhalation of labor. Therefore, i constitutes the cutting part corresponding to the plastic surgery, and, in addition, for the purpose of removing cartilage or small bone chips for the purpose of supplying and cutting the bones, U.S. Patent No. 5,269,798, No. 53 and No. 5,364,395. However, this == Spin!: The piece performs cutting, if there is rolling, the pair will be revealed; /g's knife operation will be very Danger. In addition, because this method can only remove small protrusions or those parts that are sucked into the outer tube, etc., the sleeve is used for plastic surgery, for example, on the face to reduce the width of the face. A knife or saw, and one of the quick and efficient hand-held appliances is used to efficiently use a hand-held appliance that is mainly used for a power type, surgical plastic surgery. As described above, for the surgical whole bamboo ^ Purpose of surgery The cutting saw can be used to cut a corresponding 51. The old hammer can use the grinding bone. It can be used for shaping the face on the face; grinding a large number of bones in a short time, " Bleeding, swelling, nerve damage, and muscles and bone tissue that will be removed from the ground bones

The particles are minimized. When the cutting can be performed by W j M to the saw or the file is executed in large quantities

Its slow operating speed increases the fatigue of the surgeon, which in turn reduces the attention of the surgery. Power or pneumatic hand tools have high cutting speeds due to frictional heat generated during bone cutting operations, and bone fragments that are crowded on the mine or file may be solidified. In this case, since the bone fragments and bones inserted into the cutting teeth are rubbed, it will be difficult to continuously cut a large number of bones', and it is inconvenient to clean the cutting teeth every few seconds. The heat generated may cause the soft tissue around the knife's mouth to be burned or deformed. In order to solve this - ask, it is like acting. The salt solution is supplied to a file or saw and then sucked out together with the cut moon piece. However, because the solution inhales the orphan solution in an open space, it is difficult to inhale the bone fragments pressed by the cutting teeth, and it is difficult to inhale the cutting bone T piece at a same negative pressure in a small space in the knife. Poor inhalation efficiency. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to solve various 13 1250008 problems of the aforementioned prior art.

The hand tool of the present invention can be used in a surgical operation for bone cutting while performing the inhalation of bone fragments and the supply of a saline solution. Alternatively, the handpiece can be used in a surgical procedure for bone cutting, and only one of these functions can be performed. For example, in an example of use of a trowel, an internal groove that can be used to inhale bone fragments is formed from a guillotine surface to one end of a rod and guided to a sipe of the bone fragment, and the protection member It is coupled around the file. The surgical procedure can then be performed while supplying the saline solution and inhaling the bone fragments. While the sawing system is efficient, the surgical operation can be performed while only supplying the salt solution through the protective member. Therefore, if there is no special restriction, then it is applied to the hand-held appliance. The accessory is wrong and the attachment of the doll can have various shapes. However, conventionally known trowels and saws have many limitations and problems in performing reforming operations due to their structural characteristics.
