FIG. 1 shows an advantageous feature of a visual stripping device according to the invention having a double-edged rotatable scalpel. A partial longitudinal cross-sectional view of one embodiment is shown. The grip 1 seen in the diagram is the control of the device. To ensure flexible operation, it can be configured to resemble a pistol grip. The operation lever has a finger rest 211 and a guide pin 2b in the same way as the trigger. -2 and the guide tube 3 including the drive mechanism 4. The knife operating shaft 5 is rotated inside. A rotatably supported guiding tube 3 has a stripping head at its free end. The head part 6 itself surrounds a rotatably supported female I. There is.

In a simpler embodiment, the thigh stripping device according to the invention has a rotatable mechanism. a fixed knife p, an operating lever 2 and a mechanism coupled thereto; The knife operation shaft 5 is missing.

In the embodiment of the invention according to FIG. 1, the operating lever 2 is operatively connected to the drive mechanism 4. For this purpose, a rotary cylinder 10, preferably supported on ball bearings, is provided. Supporting the drive pin 8 that engages with a certain groove 9, the operating lever 2 is pulled completely backwards. when the rotating cylinder 8 slides along the entire length of the groove 9. The knife 10 and the knife operating shaft 5, which can be coupled thereto, preferably have a longitudinal axis V-V. Advantageously, the rotation is about 220° around . According to this, The knife γ fixedly coupled to the knife operating shaft 5 similarly has a longitudinal axis with respect to the guide tube 3. It can rotate about 220 degrees around V-V.

The knife operation shaft 5 is connected together with the guide tube 3, the bag nand 11, and the transmission joint 12. On the one hand, it can be coupled with the gripping cylinder 1, and on the other hand, it can be coupled with the rotating cylinder 10. preferable. Figure 2 shows this by a cross-sectional view along the aA-person of Figure 1. .

The oboro stripping device according to the present invention is provided here in order to adjust its several working positions. In the embodiment shown in FIG. It may have an adjustment mechanism consisting of an adjustment ring 13 disposed on the seat 1. This adjustment ring 13 is connected to the drive bin 8 and, accordingly, to the one operating lever 2. , a guide groove 14 having a shape that can best be seen from the exploded view of the adjustment ring 13 in FIG. The drive is restricted in its movement parallel to its axis by the Works together with the moving bottle 8. As a result of the restriction and misalignment of the longitudinal movement of the operating lever 2, The rotational movement of the operation shaft 5 and, accordingly, the knife γ itself is restricted and shifted. Ru. In this way, it is possible to restrict the rotation of the knife 7 and cause it to shift. The point is important, as explained further below, and does not change per se, but the length By longitudinal movement of the operating lever 2, the relative position of which can be adjusted Allows to adjust some working positions of γ.

In the embodiment of the arm stripping device according to the invention described here, the adjustment ring 13 There are four operating positions, namely, the uppermost part of the thigh to be extracted and separated in Figure 3. a first position in which the stripping device head 6 is held open in order to introduce In order to prevent the thigh from coming out, the scalpel 7 locks the peeling device hand 6. the second position, and perform a frontal cut with a scalpel 7 to cut the oborosa from the oborosheath and muscle. position 3, and the position shown at the bottom of Figure 3, where the oboro is divided to remove the key from the muscle. position 4 can be adjusted.

These operations or possibly In order to be able to perform different operations correctly, the vaginal stripping device is , in addition to the adjustment mechanism, which in this case takes the form of an adjustment ring 13, a specially shaped knife is also provided. 7 and a correspondingly designed stripping device head 6. be. As is clear from FIG. 4, the stripping device head 6 has an approximately oval shape on one side. Similar to the flared end of the guide tube 3, so as to have a circular opening 15 (FIG. 1). It is advantageous if the shape is such that part of its side is milled. this In this way, the membrane can be passed through the center of the stripping device head 6 from the front, and the membrane can be passed through the elliptical side. It can be pulled out through the opening 15. The stripping device head section 6 includes a stripping device head. A slit 16 forming a passage between the end of the section and the oval opening 15 is provided. , the pus can be passed through the device by pinching it. Due to this, both sides are fused, Therefore, it is possible to insert the undivided thigh into the peeling device head 6. However, if the slit 16 is missing in the stripping device head 6, this is a defect. It is possible. This is because when the stripping device head section 6 has such a configuration, The free end of the oboro to be extracted and separated is peeled off through the center opening 17 (first 6) and the side opening 15. In this case, intentionally In order to avoid injuring the thighs, the slit 16 should be at least at its front end. Be sure to make sure that the chamfered part 16m continues to the end of the stripping device head. It is possible.

Inside the peeling device head 6 configured in this way, there is similarly a substantially cylindrical tube. It is advantageous to arrange the knife 7 formed as shown in FIG. corresponds approximately to the oval opening 15 of the stripping device head 6; It has a larger milling recess 18. For the female T, it is the adjustment ring 13. When it is in the first position, it overlaps the slit 16 of the peeling device head 16. , it is preferable to have a conduit 19 that allows the introduction of oboro. In that case, the conduit 19 It shall not have any sharp edges and shall have a chamfered portion 19m at its front end. Advantageously, however, one edge of the milling recess 18, as shown in FIG. In the fourth position of the adjustment ring 13, the edge 18& is It is sharply ground like a knife so that it can separate the pus by parts. Should. In the second position of the adjustment ring 13, the knife 7 is aligned with respect to the guide tube 3. , therefore, with respect to the stripping device head 6, the stripping device is rotated about the longitudinal axis V-V. Rotate until the lits 16 are covered. As a result, the pus is removed from the device head 6. It will be introduced in 2018, and it will no longer be removed from there.

At this point, the blind stripping device according to the present invention is slid forward along the oboro and the gable sheath. can be done.

Therefore, the shoulder stripping device, that is, the stripping device head 6 is used to remove the contributing tissue or adhesions. Alternatively, upon hitting another frontal obstacle, the adjustment ring 13 moves to its third position. In that position, the slit 16 is covered and the oval opening 16 is open. However, the knife 7 can be moved around the longitudinal axis V-V by operating the operating lever 2. The center can be rotated in both directions by a predetermined angle of approximately 40°. So As a result, the cutting edge 20 (Figs. 1 and 6) continues along the circumference of the dowel. The front area of the scalpel 7 that is being It operates in such a way that it can be separated from the attached part without being separated. surroundings The inner part 21 (Fig. 1) of the scalpel 7 that continues to the cutting edge 20 along the Advantageously, it is chamfered to prevent it from being damaged inside the base 7. Ru. This also causes the intestine inside the female 1 to become even better. .

Once the key has been exposed for a sufficient length and/or severed from the muscle attachment, The pus is removed in the fourth position of the adjustment ring 13, i.e. when the scalpel operating shaft 5 is aligned with the longitudinal axis V. - the operating lever so that maximum rotation can be made with respect to the guide tube 3 with respect to V; 2 is as sharp as a knife in the milling recess 18 when pulled back as far as possible. The thigh can be separated by a sharply ground edge 188 to protect it from the surgical wound. It can be pulled away from the A hazy stripping device according to the present invention according to FIGS. 1 to 6 When used, the thigh is still attached to the body in the area of the surgical wound. . On the other hand, in a simpler embodiment of the thigh stripping device according to the invention, the thigh stripping device Since there is no slit 16 in the head part 6 and no conduit 19 in the female 7, if you use this, In some cases, the pus separated from the muscle attachment area is removed using a front scalpel without dividing the m. It is possible to make a stump from the wound.

As described above, in the embodiment of the viscera removal device according to the present invention described with reference to the drawings, the operation The operating lever 2 is loaded with a spring, and the spring located on the grip lever 1, but not shown in Figure 1, is loaded with a spring. Therefore, the operating lever 2 is always at the starting position where it protrudes as far as possible from the grip 1. It is advantageous to be pressed by In this case, slightly bend or straighten your index finger. You can move the operating lever back and forth with just the The knife 7 will be rotated in both directions. The rotational movement of the knife is controlled by adjusting ring 1. According to the adjustment position of 3, it is neither small nor thick, and it also slides about its center line. has been done.

The transmission joint 12 operatively connects the rotating cylinder 10 and the knife operating shaft 5 to each other, Assembling the thigh stripping device according to the present invention, that is, the knife operation shaft 5 is contained inside. The installation of the guide tube 3 in the state shown in FIG. Advantageously, it is configured such that only relative rotational positions are possible. This way The structure of the transmission joint is known.

The thigh stripping device according to the present invention can be used for a single grip 1 and for various pus stumps. It can be used with a guide tube 3 formed in length and thickness. Stripping device The cross section of the head part 6 is approximately round, and the pus passed through the scalpel 7 is Do not make any contact with the sharp edges of the device in any position other than the operating position for dividing the knee. By being intouchable, the key removal device according to the present invention removes pus and pus along the key sheath inside the body. While being extruded, the material is moved back and forth arbitrarily and the longitudinal axis V-V can be rotated around the There is no risk that the shaft passing through the door portion 6 will be damaged. Therefore, according to the present invention Using the oboro stripping device, the thigh stump from the body can be removed by this kind of known technique mentioned at the beginning. The device is considerably easier to use. Various, reliable settings of the thigh stripping device according to the invention The possible operating positions make the surgeon's work easier. In addition, a rotatable knife and The simplest oboro stripping device of the present invention has no operating mechanism and only has a front knife. This embodiment, in comparison to the previously described known ablation device, removes the oboro to be stumped from the body. For the first time, surgeons are able to expose the tissue and extract and separate it from the muscle. In this sense, it has important advantages. The extraction separation from this muscle is the extraction The resulting thigh is significantly longer than if it were similarly divided at the muscle attachment using the traditional method. It is further advantageous in that it is easy to use.

The individual structural solutions of the thigh stripping device according to the invention described above can be adapted as required. may have a different appearance and accommodate the number of operating positions of the adjusting ring 13. It is self-evident that it can be easily increased or decreased, and it is easily understood by 6D and experts. So, for example In the present invention, there is no slit 16 in the stripping device head part 6, and there is no conduit 19 in the knife 7. In the case of the evisceration device according to There are two operating positions: the operating position of the intestine, and the operating position of the intestines that are passed through. It is possible to do so. In some cases, the thigh stripping device according to the invention may be used in a bag. It is also possible to use a device for fixed mounting without the Nand 11 and transmission joint 12. Although this makes cleaning the device difficult, it is useful for surgeons to use the thigh peeling technique of the present invention. There is no effect on the operation and application ability of the extraction equipment. If necessary, pus removal according to the present invention The grip 1 of the device is further explained below with reference to FIGS. 7 and 8. However, it can be configured differently from the pistol grip. Also, the peeling device The pad portion 6 and the female 7 rotatably attached therein are configured differently. It is also possible to remove the pus from the body and introduce it from the center of the front. However, it remains possible to take it out from the side, and the sharp edge of the scalpel and the key Care must be taken to avoid unintentional contact in each case. Adjustment ring 13 Alternatively, if necessary, control the limit of the knife's 70-rotation movement at a certain operating position. This is not done by restricting the longitudinal movement of the operating lever 2, but by acting on the rotating part. Other adjustment mechanisms can be provided. Furthermore, it is mechanically separated from the membrane cutting scalpel. For example, a separate pipe such as a pipe disposed between the guide pipe 3 and the knife operating shaft 5 may be It is also possible to provide a separate face-cutting scalpel that can be operated via separate axes. It is.

This makes it possible, for example, to electrically operate the front cutting knife.

Other modifications to the haziness stripping device according to the present invention as described above are completely possible. , are within the scope of the invention.

FIG. 7 shows a second advantageous embodiment of the hazy stripping device according to the invention in a partial longitudinal section. It is shown. This is because the grip 25 is not shaped like a pistol grip, but rather a screwdriver. It has a grip-like shape, and the adjustment mechanism is operated by rotational movement rather than linear movement. This differs from the haziness stripping apparatus shown in FIGS. To the present invention Other components of the thigh stripping device, such as the thigh stripping device head 6 and its A knife 7 placed inside, a guide tube 3 and a knife operating shaft 5 placed inside the guide tube 3, etc. In terms of its arrangement and function, it almost corresponds to the components of the first embodiment described above. However, the following 5 forces and grips on the knife and knife operation shafts are required The guide tube 3 is positioned so as not to rotate in the grip, and the guide tube 3 is rotatable relative to the grip. It is convenient to have the difference that

In this embodiment of the recommended stripping device according to the invention, it is possible to use the scalpel as previously described. In this case, in order to produce an alternating rotational movement with respect to the end portion 6, the stripping device 7 is When the intestine is removed, the head 6 of the intestine removal device is rotated relative to the scalpel 7. With respect to the gripping arm 25 about the longitudinal axis V-V of the device, with certain limitations: This is done by a rotatably arranged lever 26, and the shape of this lever is It is shown in FIG. This lever 26 is located on the grip 25 and is spring loaded. The lever 26 cooperates with a longitudinal slide 27 which preferably engages a recess 29 in the lever 26. The matching positioning bin 28 is supported. The recess 29 is arc-shaped and the lever 26 is Therefore, the function of limiting the alternating rotational movement of the stripping device head 6 with respect to the knife 7 is do. Conveniently, the recess 29 continues into the blind hole 30 in the area of one end thereof. , the positioning pin 28 causes the longitudinal slider 27 to move back against the force of the spring. Sometimes the blind hole 30 is penetrated so that further rotation of the lever 26 is impossible. can be done.

As a result, a fixed operating position of the scalpel 7 of the stripping device head 6 is determined. , in that position, the previously described threading and stripping device head 6 is closed laterally. There is. This operating position is shown in FIG. 8, which shows the stripping device head 6 and knife 7 from the front. It is represented by 8. The pipe line 19 is misaligned with respect to the slit 16, so Therefore, it is impossible for the thighs drawn into the head part 6 of the stripping device to slip out from the head part. Noh de chiru.

The position can be adjusted by pulling back the longitudinal slider 27 a little and rotating the lever 26. The positioning pin 28 is removed from the blind hole 30 and placed in the lever 26 and in the recess 29, i.e. , given a limited freedom of movement by its central part. This is shown in Figure 8. In the operating position, the stripping device head of the above-mentioned frontal cutting scalpel is thereby removed. alternating rotational movements relative to the parts, in which case the rotational movement Lit 16 never opens. Depending on the case, the longitudinal slider 27 or , when the positioning pin 28 associated with it is pulled back to another height of the recess 29 Only then can the lever 26 be rotated further, but as a result the stripping device head The door portion 6 opens laterally when the slint 16 and the conduit 19 are aligned.

This operating position is illustrated by FIG. 8C. The positioning bin 28 is completely recessed. When the longitudinal slider 27 is completely moved back until it exits the section 29, the lever 26 is released so that the thigh cannot rotate enough to be separated in the manner previously described. I can do it.

This linear embodiment of the recommended stripping device according to the invention also requires no inventive action. without the need for alternating rotational movements and/or adjusting mechanisms different from those described. It is clear to experts that it is possible to configure

The haze removal device according to the invention can be applied to the human or animal body by taking appropriate dimensions. It is obvious that it can also be used to extract and separate vessels other than pus from the body. especially With this device, it is possible to easily remove varicose veins.
