Other accessory devices, such as a light source holder (not shown) to mount the light source or an arm holder (not shown) to mount the surgical robot arm, may be further installed or installed in other ways.

The skin holder part 20 is a component inserted between the patient's skin and the tissue, and may be formed in a plate shape as a whole for easy insertion. However, for installation of the above-described suction pipe 12, laparoscopic holder 16, it may be formed in a slightly bent form, such as a portion of the cylinder rather than a flat plate having a single cross section.

In the case of surgery to incise and lift the skin, such as a laparotomy, the area or shape of the skin to be lifted varies depending on the surgical site. The skin holder 20 according to the present embodiment is deformed appropriately according to various situations. This can be done more effectively and reduces the risk of injury to the patient's skin.

The embodiment shown in FIG. 1 is a case in which the skin holder 20 supports the skin of a larger area, thereby securing a space necessary for surgery and reducing the risk of injury to the skin by not applying local pressure to the skin. .

That is, according to the present embodiment, the skin holder part 20 includes a support plate 21 and a plurality of support wings 22 coupled to overlap each other like a fan about a predetermined axis of the support plate 21. Therefore, the skin holder 20 is inserted between the skin and the tissue when the support blade 22 is folded, that is, when the skin holder 20 is in the shape of a straight plate, and then the plurality of support blades 22 are fan-shaped. By expanding the shape, the skin holder part 20 can support the skin of a larger area.

As such, when the skin holder supports a large area of the skin, more space for surgery may be secured, and the pressure applied to the skin of the patient is reduced, thereby reducing the risk of injury to the skin.

In order to make the skin holder portion 20 into a plurality of overlapping support wings 22 like a fan and to be expanded in a fan shape after being inserted into the affected part as in the present embodiment, in the case of the manual method, an operation lever or the like is externally provided.

In the present embodiment, the case in which the fan mechanism is borrowed to increase the area supported by the skin holder part 20 has been described as an example. However, the support area of the skin holder part 20 may be adjusted using other mechanisms apparent to those skilled in the art. Of course, it can increase.

Figure 2 is a side view showing a surgical auxiliary instrument according to another embodiment of the present invention, Figure 3 is a side view showing a surgical auxiliary instrument according to another preferred embodiment of the present invention. 2 and 3, the handle 10, the suction pipe 12, the body 14, the laparoscopic holder 16, the skin holder 20, the support plates 23 and 23 ′, the support wings ( 24, 24 ') are shown.

This embodiment relates to a surgical auxiliary instrument having the same structure as the embodiment shown in Figure 1, except that the embodiment shown in Figure 1 skin holder portion to increase the area supported by the skin holder portion 20 While a plurality of support wings 22 are superimposed on 20, the present embodiment is characterized in that the skin holder 20 is deformed according to the shape or depth of the skin to be lifted during surgery. do.

That is, the skin holder 20 of the instrument according to the present embodiment is composed of a support plate 23 and a support wing 24 hinged to the support plate 23, the support wing 24 is shown in FIG. As described above, the angle with respect to the support plate 23 may be changed, so that the skin holder 20 may be properly bent according to the shape of the skin during surgery.

For example, when cutting the facial skin and inserting the skin holder to lift the skin for facial plastic surgery, conventionally, only a straight skin holder can be used to injure the skin by applying unnecessary pressure to the skin at the end of the skin holder. Although there was a risk of causing the skin holder 20 to be adjusted downward by a predetermined angle as shown in the present embodiment, the pressure applied to the skin at the end of the skin holder 20 is reduced so as not to injure the skin. can do.

On the contrary, even when it is necessary to lift the skin further from the end of the skin holder 20, the instrument according to the present embodiment can be appropriately used in various surgical situations simply by adjusting the angle of the support wing 24 upward. As described above, the skin holder 20 which can bend the support wing 24 by a predetermined angle according to the shape of the skin can be easily and simply applied even in various surgical situations, while accurately securing the space required for the surgery and in the surgical process. It is possible to reduce the risk of excessive injury to the patient's skin.

In the embodiment shown in Figure 2 illustrates a case in which the support wing 24 is hinged to the support plate 23 to rotate, the coupling of the support wing 24 and the support plate 23 is not necessarily limited to the hinge coupling. If the support wing 24 is a coupling method that can be bent at a predetermined angle with respect to the support plate 23, other coupling structures that are obvious to those skilled in the art, such as pin coupling, screw coupling, gear coupling can also be applied.

In order to make the support wing 24 rotate in a predetermined angle with respect to the support plate 23 as in the present embodiment, and to allow the support wing 24 to rotate a predetermined angle after being inserted into the affected part during surgery, In the case of the system, an operating lever or the like is installed on the outside, and in the case of the automatic system, a driving unit coupled to the rotating shaft of the support blade 24 and an input signal corresponding to the degree of rotation of the support blade 24 are generated and transmitted to the driving unit. It is recommended to install an operation unit such as an operation switch for operating the controller.

When the skin holder part 20 is deformed in an automatic manner, the skin holder part 20 may be fixed in its deformed state to secure a space for surgery. On the other hand, depending on the surgical situation, it is also possible to rotate the support wing 24 in advance by a predetermined angle and then inserted into the affected part.

On the other hand, as shown in the embodiment shown in Figure 3, it is also possible to couple the support wings to the support plate stretchable. That is, the skin holder 20 is composed of a support plate 23 'and a support wing 24' coupled to the support plate 23 'so as to be stretchable. It can be lengthened or shortened appropriately.

Thus, without having to provide a number of auxiliary instruments according to the surgical site by inserting the skin holder 20 to the affected area of various depths only by the instrument according to the present embodiment by lifting the skin efficiently to secure a space suitable for surgery You can do it.

Stretch coupling of the support wing 24 'and the support plate 23' may be applied to various coupling structures apparent to those skilled in the art, such as corrugated pipe or bellows type, slide type, telescope type.

In addition, in order to expand and contract the support blades 24 'with respect to the support plate 23', an operating lever or the like is installed outside in the case of the manual method, and in the case of the automatic method, a drive unit coupled to the support wings 24 'and the support wing. An operation unit such as an operation switch for operating the drive unit can be provided by generating an input signal corresponding to the degree of expansion and contraction of 24 'and driving the drive unit.

When the skin holder part 20 is deformed in an automatic manner, the skin holder part 20 may be fixed in its deformed state to secure a space for surgery. On the other hand, depending on the surgical situation, it is also possible to stretch the support wing 24 'by a predetermined length and then insert it into the affected part.

In the surgical auxiliary instrument according to the present embodiment, one surface of the skin holder part 20 is in contact with the skin during surgery, and thus, when the surface of the skin holder part 20 is in contact with the skin, the skin is properly slipped. It is hard to support, which may cause skin injury or medical accidents during the surgery.

Therefore, it is preferable to perform an anti-slip treatment on the surface of the skin holder part 20 in contact with the skin so that the skin holder part 20 does not slip in a state in which the skin holder part 20 supports the skin. The anti-slip treatment may be performed by surface treatment, such as embossing the surface of the skin holder portion 20 or polishing treatment to form a predetermined pattern, and forming a plurality of grooves or protrusions or surface material. Various methods may be applied, such as a material having a large coefficient of friction.

On the other hand, when one surface of the skin holder 20 is in contact with the skin in this way it can not be excluded that the injury to the skin depending on the shape or surface state of the skin holder 20. In such a case, the possibility of causing injury to the skin can be reduced by supporting the skin in a non-contact manner as described below.

Figure 4 is a side view showing a surgical auxiliary instrument according to another embodiment of the present invention. Referring to FIG. 4, there is shown a skin 1, a handle 10, a suction pipe 12, a body 14, a laparoscopic holder 16, a skin holder 20, and an air nozzle 26. .

The present embodiment relates to a surgical auxiliary instrument having the same overall structure as the above-described embodiment, while the above-described embodiment is characterized in that the area, angle, and length of the skin holder part 20 are modified. The embodiment is characterized in that the skin holder 20 supports the skin 1 in a non-contact manner.

That is, after forming a plurality of air nozzles 26 on the surface of the skin holder portion 20 in contact with the skin 1, the skin holder portion 20 is inserted between the skin 1 and the tissue. By spraying high pressure air through the air nozzle 26, the skin 1 may be lifted up without the skin 1 contacting the skin holder 20.

By adjusting the pressure of the air injected through the air nozzle 26 it is possible to control the degree of lifting the skin 1, thereby minimizing the injury to the skin (1) by using the auxiliary instrument.

As another modification of the above-described embodiment, it is also possible to form a space for surgery by pulling the skin from the outside without inserting the skin holder portion 20 between the skin and the tissue. That is, when the skin holder part 20 comes into contact with the skin from the outside, a vacuum nozzle is formed on the lower surface of the skin holder part 20 in contact with the skin and the skin is held by adsorbing the skin through the vacuum nozzle. It can be pulled and supported. This creates a predetermined space for surgery between the skin and the tissue.

The vacuum nozzle can effectively pull the skin by forming a plurality of the skin holder 20 over the entire area in contact with the skin. In addition, it is desirable to appropriately adjust the number, shape, vacuum pressure, and the like of the vacuum nozzle in order to prevent the problem of bleeding on the skin at a specific position where the vacuum nozzle touches.

On the other hand, in order to minimize the injury that can be applied to the skin, in addition to the above-described embodiments by lifting the skin by the skin holder 20 to detect the load (load) on the skin to minimize the load on the skin Method is also possible.

That is, the sensor is installed in the skin region into which the instrument according to the present embodiment is inserted, and the sensor detects a load applied to the skin. The sensor may be separately installed on the skin or coupled to the end of the skin holder 20 to sense a rod such as a tension in which the skin is pulled during the procedure.

It may be determined whether or not the skin is damaged according to the detected load value of the skin. That is, if the load reference value for injury to the skin is stored in advance or the value is measured and stored as the reference value from the patient's skin before the operation, the skin value of the skin from the load value caught on the skin in the state of lifting the skin by the skin holder 20 Injury or degree of injury can be determined in advance.

Furthermore, the controller may further include a control unit for deforming the skin holder unit 20 so as not to cause injury to the skin automatically according to the signal detected from the sensor. The control unit receives the measured value of the sensor and compares the stored reference value and transmits a control signal to deform the skin holder 20 when the measured value exceeds the reference value.

In order to automatically deform the skin holder part 20, the driving part installed in the skin holder part 20 receives a signal from the control part and extends the support wing, bends it by a predetermined angle, or stretches it by a predetermined length. )

As a result, even when the skin holder part 20 lifts the skin and the skin may be damaged, the skin holder is automatically deformed in a direction to minimize the load on the skin.

For example, when the rod on the skin at the end of the skin holder portion 20 exceeds the reference value, the control unit receives the measured value from the sensor to expand the area of the support wing, or to drive the support wing downward by a predetermined angle, By reducing the length of the support wing, that is, by reducing the extent to which the skin holder 20 supports the skin, damage to the skin at the end of the skin holder 20 can be reduced.

Therefore, the sensor according to the present embodiment is not necessarily installed in one place, but may be provided in plural in areas where the skin is concerned if necessary. Even if the skin holder 20 is automatically deformed, the space necessary for surgery must be secured, and thus an upper limit value may be set such that the skin holder 20 is no longer deformed according to the setting of the operator.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
