[0039] FIGS. 1 to 3 illustrate a handling stabilizer for precision surgery according to various embodiments. Hereinafter, a handling stabilizer for precision surgery according to the present invention will be described with reference to FIGS. 1 to 3.

[0040] First, referring to FIGS. 1 and 3, the handling stabilizer for precision surgery according to the present invention can assist in the use of a multi-joint link type surgical instrument coupled to a multi-joint link mechanism (L) as in FIG. 1, and can also assist in the use of a hose type surgical instrument as in FIG. 3.

[0041] Regardless of the type of surgical instrument, the holder portion (400) is configured such that the surgical instrument (100) is attached to one end. Here, an example of the surgical instrument (100) may be a syringe, and in particular, it may be a syringe in which the piston automatically reciprocates through a motor, etc. In the case of a surgical instrument equipped with a motor, etc., the weight of the surgical instrument is heavy, and therefore, in order to perform precise invasive procedures in the millimeter range, it is necessary to reduce the load on the operator's arm by reducing the weight of the surgical instrument.

[0042] To this end, the surgical instrument (100) is installed on the precision surgical handling stabilizer of the present invention so that the surgical instrument is lifted upward and the load can be reduced. However, if the upward traction force of the surgical instrument is too great, the operator must instead pull the surgical instrument downward to control the precision invasiveness of the syringe, so it is necessary to appropriately offset this.

[0043] Specifically, the lifting portion (200) is configured to be coupled to the other end of the holder portion (400) to which the surgical instrument (100) is coupled at one end, thereby providing a traction force to cause the holder portion (400) to rise. That is, the surgical instrument (100) coupled to the holder portion (400) can be lifted together with the holder portion (400) through the action of lifting the holder portion (400) itself by the lifting portion (200).

[0045] Hereinafter, the holder part (400) and the lifting part (200) will be explained through an example.

[0047] First, an embodiment of a multi-joint link type surgical instrument is described. As shown in FIGS. 1 and 2, a degree of freedom can be granted to the movement of the surgical instrument (100) through a multi-joint link mechanism (L) composed of multiple links. At this time, the holder part (400) to which the surgical instrument is coupled is the last link of the multi-joint link mechanism (L) composed of multiple links.

[0048] Specifically, the multi-joint link mechanism (L) includes a central axis (C) formed by extending upward. At this time, the lifting part (200) and the procedure part (A) are connected based on the central axis (C). A procedure device (100) can be connected to the last link of the procedure part (A), that is, one end of the holder part (400).

[0049] At this time, a wire or the like for supplying power to the surgical instrument (100) may be embedded inside the multi-joint link mechanism (L), and the surgical instrument (100) and the holder part (400) are connected to each other by a connector so that the surgical instrument can receive power.

[0050] The surgical instrument (100) can receive power from the main body of the surgical instrument, and its operation can be controlled from the main body of the surgical instrument.

[0051] Meanwhile, a weight (250) is provided in the lifting part (200). Gravity acts on the weight (250) provided in the lifting part (200) to generate a traction force on the treatment part (A), and at this time, as the treatment part (A) rises, the holder part (400) connected to the treatment part (A) rises, and the treatment device (100) connected to the holder part (400) can rise.

[0052] In particular, the weight (250) is coupled to allow rotation with respect to the central axis (C). Accordingly, the traction force on the treatment area (A) can be changed depending on the distance between the weight (250) and the treatment area (A).

[0053] That is, if the weight (250) is moved closer to the center axis (C), the traction force becomes relatively weaker, and if the weight (250) is moved further away from the center axis (C), the traction force becomes relatively stronger.

[0055] Next, an example of a hose-type surgical instrument is described. In the hose-type surgical instrument illustrated in FIG. 3, the movement of the surgical instrument (100) is given a degree of freedom by the movement of a flexible hose (H) and a lifting part (200) that is rotatably coupled around the main body of the surgical instrument.

[0056] Specifically, the other end of the lifting part (200) is connected to the main body of the surgical instrument (100). The lifting part (200) is connected to the main body of the surgical instrument (100) in a ball hinge manner, so that it can freely rotate and move in a 360-degree direction.

[0057] In addition, the surgical instrument (100) coupled to one end of the holder part (400) is connected by a flexible hose (H), and since a wire is embedded in the hose, the degree of freedom of movement of the surgical instrument is higher than that of a multi-joint link mechanism.

[0058] Meanwhile, the lifting part (200) and the holder part (400) can be connected to each other via a spring. Specifically, one end of the spring (S) is connected to the lifting part (200) and the other end of the spring (S) is connected to the holder part (400), and at the same time, the lifting part (200) and the holder part (400) can be joined in a hinge manner so that they can rotate at a certain angle.

[0059] That is, the spring (S) connected to the holder (400) is tensioned by gravity acting on the holder (400), and thus a restoring force is generated in the spring (S), which can generate a traction force to raise the holder (400). Additionally, as the user pulls the surgical instrument downward, the spring (S) connected to the holder (400) is tensioned, and a restoring force is generated in the spring (S), which can generate a traction force to raise the holder (400).

[0060] Specifically, in the case of a hose-type surgical device, a wire can be extended from the main body of the surgical device and coupled with the surgical device (100) to supply power to the surgical device (100). At this time, a portion of the wire can be coupled to the holder part (400), and the wire can be extended and coupled with the surgical device (100) at the end of the holder part (400). As the user pulls the surgical device, the wire or hose (H) lowers the holder part (400), thereby tensioning the spring (S).

[0062] Meanwhile, the present invention developed a precision surgical handling stabilizer that can reduce the load on the operator's arm by supporting the forearm (F) of the user's arm through a support member (300) to offset the load of the user's arm acting downward and the traction force of the lifting member (200) acting upward, based on the observation that if the upward traction force of the surgical instrument is too large, the operator may instead pull the surgical instrument downward, making it difficult to control the precision invasiveness of the syringe, and if the upward traction force is too small.

[0064] More specifically, one end of the support member (300) is connected to the holder member (400) or the surgical instrument (100), and the other end is supported by the forearm (F) of the user of the surgical instrument. The user of the surgical instrument holds the surgical instrument with their hand and bears the load on their forearm, and the position of the forearm is controlled using the operator's shoulder muscles. Consequently, when precisely controlling a heavy surgical instrument, the operator easily feels fatigue in their shoulder muscles, and it becomes difficult to guarantee the precision of the procedure during prolonged use.

[0065] In this regard, by directly supporting the operator's forearm, the operator can perform precise procedures using only wrist movements while stably resting the weight of the arm on the support. Additionally, by preventing the operator from feeling the weight of the forearm, fatigue in the shoulder muscles can be significantly reduced, and precise procedures can be continuously performed even during prolonged procedures.

[0066] This is because the operator's arm consists of the armpit, upper arm, forearm, and wrist, but supporting it only at the armpit makes it difficult to withstand the weight of the arm itself and the force required for precise control of the surgical instrument, and the upper arm is generally at an inclined angle, making it difficult to support the load. Additionally, the movement of the wrist may be restricted, so the forearm is ultimately the most suitable position to offset the load of the operator's arm and the surgical instrument.

[0067] FIG. 2 illustrates the use of a handling stabilizer for precision surgery according to one embodiment of the present invention. Referring to FIG. 2, the operator grasps the surgical instrument (100) and moves it to the skin of the patient. At this time, the surgical instrument (100) is pulled upward by the lifting part (200), and the operator can pull the surgical instrument (100) downward to balance the pulling force of the lifting part (200).

[0068] That is, according to the present invention, the practitioner's forearm is supported on the support portion (300), so the user can balance by counteracting the traction force of the lifting portion (200) not only through the hand but also through the forearm.

[0069] Furthermore, as the treatment area changes, the operator moves the treatment instrument (100). At this time, as the direction of the force changes continuously, the operator is forced to pay greater attention to moving the treatment instrument (100). However, since the operator's forearm, which is supported by the support member (300), is synchronized with the movement of the treatment instrument and can continuously assist the operator from the support member (300), there is an advantage that stable treatment is possible.

[0071] Meanwhile, the support member (300) includes a connecting member (330) for connecting the support member (300) to a holder member (400) or a surgical instrument (100), and a support member (370) for supporting the forearm (F) of the practitioner.

[0072] The support member (300) can be connected to the holder member (400) or the surgical instrument (100), and the connection position can be changed according to the length of the operator's arm or the shape of the surgical instrument (100). Additionally, the connection member (330) is connected to the holder member (400) or the surgical instrument (100) in the shape of a ring, and the ring-shaped connection member (330) is formed to be disassembled and assembled, so that fine adjustment of the connection position is possible in the holder member (400) or the surgical instrument (100), allowing the appropriate position to be adjusted regardless of the type of surgical instrument or the length of the operator's arm.

[0073] Meanwhile, the support (370) is formed by extending downward from one end of the connecting part (330), and the shape of the support (370) is sufficient to support the operator's arm. For example, the support (370) may be in the shape of a hook as shown in FIG. 4 or in the shape of a ring as shown in FIG. 5.

[0074] The height of the stand (370) itself is sufficient when the practitioner’s hand is positioned at the end of the surgical instrument (100) when the practitioner places their forearm (F) on the stand (370), but since the surgical instrument may also vary depending on the type, support members (300) of various heights are provided so that they can be replaced and used as needed.

[0076] Meanwhile, a connector is provided between the connecting part (330) and the stand (370) to connect the connecting part and the stand (370). Referring to FIGS. 4 and 5, the connector (350) is a part on which a load is applied by the operator's forearm (F), and it is preferable to make it of a flexible material that has a certain degree of rigidity.

[0077] That is, as the operator's arm moves as a whole, the stand (370) can move, and the connector (350) connected to the stand (370) can be partially bent by the load of the operator's forearm (F). Therefore, the connector can be formed of a material that is more flexible than the stand (370) or the connecting part.

[0078] For example, the connector (350) is formed of silicon and may have a hardness of 60 or higher. Hardness is one of the physical properties that indicates how hard or strong a material is. Hardness is generally measured according to a specific test method and may be measured by test methods such as Brinell, Vickers, or Rockwell, but it is desirable to have a hardness of 60 or higher regardless of the method.

[0080] Meanwhile, to further explain the connector (350), connecting tabs (355) are provided at both ends of the connector (350). A pair of connecting tabs (355) are provided at both ends to connect the joint part (330) and the mounting bracket (370).

[0081] The outer surface of the connector (350) is formed of silicone, and the connector (350) can be inserted and injected integrally with the joint tab (355) through a mold.

[0082] Meanwhile, since the stand (370) must be able to withstand the load from the operator's forearm (F), it may be formed from ABS (acrylonitrile butadiene styrene) material. ABS is one of the polymers used as plastic, and it has high tensile strength and shock absorption capabilities, so it does not deform even under impact, and it is easy to process and suitable for molding into a desired shape.

[0083] Likewise, the connecting part (330) can also be formed of ABS material.

[0085] Meanwhile, the support member (300) itself can be molded as a single unit. That is, referring to FIG. 6, the connecting member (330), the connector and the stand (370) are molded as a single unit, and the support member (300) itself can be connected to the holder member (400) or the surgical instrument (100) through the connecting member (330).

[0086] At this time, the connector (350) may be extended downward as in FIG. 4 and 5, or the downwardly extended end as in FIG. 6 may be bent in the direction in which the surgical instrument (100) is connected, and the support (370) may be positioned by extending downward again from the bent end.

[0087] However, due to the variety of the shape of the operator's arm, the stand (370) may be formed separately from the connecting part (330) and the connector (350) and connected to the other end of the connector (350) via a hinge method. That is, the stand (370) itself may be rotated within a certain angle range from the other end of the connector (350), so that it can be fixed in a position that provides the most stability to the operator and allow the operation to be performed.

[0089] According to the above structure, a precision handling stabilizer can be provided to assist the operator in performing a precise procedure while reducing the burden on the operator's arm, and according to the present invention, there is an advantage that the movement of the operator's wrist and fingers during the procedure becomes free.

[0091] Although specific embodiments of the present invention have been illustrated and described, it will be obvious to those skilled in the art that the present invention can be modified and changed in various ways without departing from the technical spirit of the invention as provided by the following claims.
