Description

[Technical field]

[0001] The present invention relates to a holding controller, and more particularly to a holding controller capable of adjusting the fixing force applied to a medical instrument or the like. [Background technology]

[0002] Generally, various medical instruments such as endoscopes, drills, suction instruments, mirrors, etc. are used in medical procedures in hospitals. These medical instruments are mainly held by the user performing the treatment directly in his / her hands, but since the user cannot hold all the necessary medical instruments, he / she may ask for the help of an assistant or may use additional auxiliary instruments that can fix the medical instruments in a specific position.

[0003] However, when an assistant is used, it is difficult for the user performing treatment to fix the medical instrument in the desired position, and when an assistant is used, although the user can fix the medical instrument in a specific position, it is only possible to simply fix and release the medical instrument, which causes inconvenience because the user cannot continuously change the angle of the medical instrument or adjust the fixing force with which the medical instrument is gripped during the treatment. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention is made to solve these problems, and its purpose is to provide a holding controller that can adjust the holding force for gripping a fixed object such as a medical instrument, and can easily change the position and angle of the fixed object in various situations. [Means for solving the problem]

[0005] In order to achieve the above-mentioned object, the holding controller of the present invention includes a holding body in which a ball portion of a ball joint connected to a fixed object is provided inside the front end and which is capable of controlling the movement of the ball portion, and the holding body includes therein a fixed pressing member capable of contacting the ball portion, an elastic member that urges the fixed pressing member forward through elastic force, and a fixing control means that contracts the elastic member backward or extends it forward.

[0006] In addition, the fixed control means is configured to rotate about an axis forming a front-to-rear direction, and the degree to which the fixed pressing member presses the ball portion can be changed by contracting or expanding the elastic member along the direction in which the fixed control means rotates.

[0007] In addition, the fixing control means can include a guard part 410 that can move in the forward and backward directions within the fixing pressing member and contracts the elastic member, and a control rod that extends rearward from the guard part so as to penetrate the elastic member and is screwed into the rear end of the holding body.

[0008] The elastic member may be a compression spring, and the guard portion may have an outer end located between an outer diameter and an inner diameter of the elastic member.

[0009] The fixing member may further include an adjustment guide plate provided at a front end of the elastic member, where the rear end of the fixed pressing member and the guard portion come into contact with each other.

[0010] In addition, the holding body may further include an auxiliary elastic member having elasticity, the auxiliary elastic member being disposed inside the fixed pressure member and in front of the fixed control means. Effect of the Invention

[0011] According to the present invention, the fixing control means expands or contracts the elastic member, and the fixing pressing member fixes or releases the ball part, so that the object to be fixed is firmly fixed or the object to be fixed can move freely. In addition, by finely adjusting the fixing control means in a state where the elastic member is maximally expanded, the fixing force for the ball part can be adjusted, so that the fixing force for gripping the object to be fixed, such as a medical instrument, can be adjusted, and the position and angle of the object to be fixed can be easily changed in various situations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The present invention proposes a holding controller that includes a holding body in which a ball part of a ball joint connected to a fixed object is provided inside a front end and the movement of the ball part can be controlled so that the fixing force for gripping a fixed object such as a medical instrument can be adjusted and the position and angle of the fixed object can be easily changed in various situations, and the holding body includes a fixed pressing member that can come into contact with the ball part, an elastic member that urges the fixed pressing member forward through an elastic force, and a fixing control means that contracts the elastic member backward or extends it forward.

[0014] The scope of the present invention is not limited to the embodiments described below, and various modifications and variations can be made by those skilled in the art without departing from the technical gist of the present invention.

[0015] Hereinafter, a holding controller according to the present invention will be described in detail with reference to the accompanying Figs. 1 to 8.

[0016] The holding controller according to the present invention includes a holding body A for fixing a fixed object 10 at a specific position and angle or for changing the angle at the position, as shown in Figs. 1 to 8, and the fixed object 10 in the present invention may be, but is not limited to, a medical instrument, and may be various types of instruments requiring the above-mentioned operation.

[0017] The holding body A may have a hollow rod-like outer shape, and as an example, as shown in Figures 1 to 4, may include a hollow case a1 with both ends open, a front cover a2 connected to and covering the front end of the case a1, and a rear cover a3 connected to and covering the rear end of the case a1.

[0018] The holding body A is provided with a ball joint 100 at its front end, and the ball joint 100 here may be a part of the object 10 to be fixed, or may be configured to be connected to the object 10. The ball joint 100 which is a part of the object 10 or can be connected to the object 10 may include a spherical ball part 110 and a rod-shaped arm part 120 extending from the ball part 110. The ball part 110 may be provided inside the front end of the holding body A, and the arm part 120 may be provided to pass through the front end of the holding body A.

[0019] As shown in Figs. 2 to 4, the holding body A is configured to be able to control the movement of the ball portion 110, and includes a fixed pressing member 200, an elastic member 300, and a fixed control means 400 therein.

[0020] The fixed pressing member 200 is provided behind the ball part 110 so as to be able to abut against the ball part 110, and can move within the holding body A according to the elastic force of the elastic member 300, and can abut against the ball part 110 when moving forward. As an example, the front end of the fixed pressing member 200 that directly abuts against the ball part 110 can be formed in a hemispherical shape so that the ball part 110 can be stably mounted. As another example, as shown in Figs. 2 to 4, the fixed pressing member 200 can include a cylinder 210 whose longitudinal section is U-shaped with an opening toward the rear or formed in a tubular shape with an opening in the front-rear direction, and a ball casing 220 that is connected to the front end of the cylinder 210 and has a hemispherical front end capable of accommodating a part of the ball part 110.

[0021] The elastic member 300 can move the fixed pressing member 200 forward by elastic force and can be made of various kinds of springs. As an example, as shown in Fig. 3 and Fig. 4, the elastic member 300 can be made of a coil type compression spring, and can be provided so that its front end abuts against the cylinder 210 and a guard part 410 described below, and its rear end abuts against the rear cover a3. In this case, it is preferable that the inner diameter of the rear end of the fixed pressing member 200, i.e., the rear end of the cylinder 210, is formed larger than the inner diameter of the front end of the elastic member 300, and the diameter of the guard part 410 is formed larger than the inner diameter of the front end of the elastic member 300.

[0022] The fixing control means 400 is configured to contract or expand the elastic member 300. As an example, as shown in Figs. 2 to 4, the fixing control means 400 can move in the front-rear direction within a cylinder 210 constituting the fixed pressing member 200, and can include a guard part 410 that abuts against the front end of the elastic member 300, and a control rod 420 that extends rearward from the guard part 410 so as to penetrate the elastic member 300 and is screwed into the rear end of the holding body A.

[0023] Specifically, the guard part 410 may be formed in a plate-like or cylindrical shape with a circular or polygonal cross section, and an outer end may be configured to be located between the outer diameter and the inner diameter of the elastic member 300. Since the guard part 410 can rotate while being in contact with the front end of the elastic member 300, a thrust bearing may be provided at the rear end to reduce friction with the elastic member 300 and ensure smooth rotation. The control rod 420 is formed in a rod-like shape having a diameter smaller than the inner diameter of the elastic member 300, and may be screwed into the rear cover a3 constituting the rear end of the holding body A by forming a screw thread on the outer circumferential surface. In addition, a portion of the control rod 420 located outside the holding body A may be configured to be interlocked with a motor (not shown) for easy rotation of the control rod 420.

[0024] Since the fixing control means 400 can rotate about the longitudinal axis of the control rod 420, which is an axis in the front-rear direction, the length of the elastic member 300 can be adjusted by rotating, and the fixed pressing member 200 can move to fix or release the ball part 110, or adjust the fixing force for the ball part 110. That is, the elastic member 300 can be contracted or expanded along the direction in which the fixing control means 400 rotates about its axis, and the degree to which the fixed pressing member 200 presses the ball part 110 changes depending on the degree to which the fixing control means 400 rotates about its axis, thereby adjusting the fixing force for the ball part 110.

[0025] Specifically, as shown in Fig. 5(a), when the control rod 420 is rotated in a direction moving backward, the elastic member 300 is contracted by the guard portion 410, and thus the fixed pressing member 200 can be released from contact with the ball portion 110. In this case, since the ball portion 110 can move freely, the fixed object 10 can be operated to have a position and angle desired by the user.

[0026] 5(b) in a state where the contact between the fixed pressing member 200 and the ball portion 110 is released, when the control rod 420 is rotated so as to move forward, the elastic member 300 is extended by an amount corresponding to the movement of the guard portion 410, and as a result, the fixed pressing member 200 presses the ball portion 110 while abutting against it. In this case, since the movement of the ball portion 110 is restricted, the fixed object 10 can be fixed at a specific position at a specific angle.

[0027] 6, when the control rod 420 is rotated slightly in a direction in which the elastic member 300 moves backward while being maximally extended, the front end of the elastic member 300, which has a larger outer diameter than the guard part 410, is bent by the force applied downward as the guard part 410 moves slightly. In this case, the object 10 to be fixed can be moved to adjust the position and angle in a state in which the fixing force against the ball part 110 is somewhat reduced (e.g., 30%, 50%, 70% of the maximum fixing force).

[0028] Meanwhile, the holding body A may further include an auxiliary elastic member 500 having elasticity, which is installed in front of the fixing control means 400 inside the fixing pressure member 200. As an example, the auxiliary elastic member 500 may be a compression spring having a smaller elastic force than the elastic member 300, as shown in Fig. 7, and may be installed in front of the guard part 410 inside the cylinder 210 to exert an elastic force in the front-rear direction. Such an auxiliary elastic member 500 prevents abrupt release of the fixing and facilitates fine control of the fixing force.

[0029] That is, since the auxiliary elastic member 500 has its front end supported by the cylinder 210 and its rear end supported by the guard part 410 due to its elasticity, even if the control rod 420 is rotated in a direction in which the elastic member 300 moves rearward in a state in which it is maximally extended, the auxiliary elastic member 500 presses the cylinder 210 with its elastic force, so that the fixing of the ball part 110 is not suddenly released, and the fine fixing force can be more smoothly adjusted. Also, the fixing force for the ball part 110 can be adjusted by the auxiliary elastic member 500 regardless of the direction of the front end of the holding body A provided with the ball joint 100.

[0030] In addition, the holding body A may further include an adjustment guide plate 600 that is provided at the front end of the elastic member 300 and abuts against the rear end of the fixed pressing member 200 and the guard part 410. As an example, the adjustment guide plate 600 may be formed in a ring shape corresponding to the cross section of the elastic member 300 as shown in Fig. 8, so that a bending phenomenon may occur when adjusting the fine fixing force. This is to prevent the elastic force from being affected when a continuous bending phenomenon occurs as the front end of the elastic member 300 directly abuts against the guard part 410.
