Description

Technical Field

[0001] This disclosure relates to a holding controller, and one specific implementation relates to a holding controller capable of adjusting the holding force used to hold an object to be secured, such as a medical device. Background Technology

[0002] Various medical devices, such as endoscopes, drills, suction devices, and mirrors, are commonly used to perform medical procedures in hospitals. These devices are primarily used by the user by holding them directly with their own hands. However, since it is impossible to grasp all the necessary medical devices, the user may require assistance from an assistant or use additional aids to hold the devices in place.

[0003] However, when assisted by an assistant, the user performing the treatment may find it difficult to hold the medical device in the desired position. While assistive devices can hold the medical device in a specific position, there are inconveniences because the device can only be secured and released: the angle of the device cannot be continuously changed during treatment; or the force used to hold the device in place cannot be adjusted. Summary of the Invention

[0004] Purpose of the invention

[0005] One aspect is to solve the aforementioned problems and provide a holding controller that can adjust the fixing force used to hold an object to be fixed, such as a medical device, thereby facilitating changes in the position and angle of the object to be fixed under various circumstances.

[0006] Technical solution

[0007] According to one aspect, a holding controller is provided, the holding controller including a holding body having a spherical portion of a ball joint disposed inside a front end and connected to an object to be fixed, and the holding body being configured to control the movement of the spherical portion, wherein the holding body includes a fixing pressure member configured to contact the spherical portion, an elastic member configured to transmit force forward to the fixing pressure member via elastic force, and a fixing controller configured to retract the elastic member backward or extend the elastic member forward.

[0008] The fixed controller can be configured to rotate axially about an axis oriented in the forward and backward directions, and the degree of pressure applied to the spherical portion by the fixed pressurizing member can vary depending on the retraction or extension of the elastic member, which depends on the axial rotation direction of the fixed controller.

[0009] The fixing controller can include a guard portion configured to move forward and backward within the fixing press member and retract the elastic member, and a control lever extending rearward from the guard portion to penetrate the elastic member and be threadedly coupled to a rear end of the holding body.

[0010] The elastic member can be formed of a compression spring, and an outer end of the guard portion can be positioned between an outer diameter and an inner diameter of the elastic member.

[0011] The holding controller can further include an adjustment guide plate provided at a front end of the elastic member, on which a rear end of the fixing press member and the guard portion abut.

[0012] The holding body can further include an auxiliary elastic member having elasticity and provided in front of the fixing controller inside the fixing press member.

[0013] Advantageous Effects

[0014] According to example embodiments of the disclosure, since the fixing press member fixes or releases the spherical portion as the elastic member is extended or retracted by the fixing controller, it is possible to firmly fix an object to be fixed or freely move a fixed object. In addition, by finely adjusting the fixing controller while the elastic member is maximally extended, it is possible to adjust the fixing force of the spherical portion, so that it is possible to adjust the fixing force of a held object, such as a medical device, and easily change the position and angle of the fixed object in various situations.

[0023] The present disclosure proposes a holding controller including a holding body having a spherical portion of a spherical joint provided inside a front end portion coupled with an object to be fixed, and configured to control a movement of the spherical portion, wherein the holding body includes a fixing pressurizing member configured to be in contact with the spherical portion, an elastic member configured to transmit a force forward to the fixing pressurizing member via an elastic force, and a fixing controller configured to retract the elastic member backward or extend the elastic member forward, the holding controller being capable of adjusting a fixing force for holding the object to be fixed, such as a medical device, thereby facilitating a change in a position and an angle of the object to be fixed in various situations.

[0024] The scope of the present disclosure is not limited to the example embodiments described below, and various modifications can be made by those skilled in the art without departing from the technical spirit of the present disclosure.

[0025] Hereinafter, reference will be made to the accompanying drawings Figures 1 to 8 The holding controller of the present disclosure is described in detail.

[0026] As Figures 1 to 8 shown in the above, the holding controller of the present disclosure includes a holding body A for holding an object 10 to be fixed at a certain position and angle, or for changing an angle of the fixed object 10 at the position. In the present disclosure, the object 10 to be fixed can be a medical device, but is not limited thereto, and can be any other type of device requiring the above operation.

[0027] The holding body A can have an external shape formed in the shape of a hollow rod. For example, as Figures 1 to 4 shown in the above, the holding body A can include a case a1 which is open at both end portions and hollow inside, a front cover a2 coupled with a front end portion of the case a1 and covering the front end portion of the case a1, and a rear cover a3 coupled with a rear end portion of the case a1 and covering the rear end portion of the case a1.

[0028] The holding body A is provided at the front end portion with a spherical joint 100. The spherical joint 100 can be a part of the object 10 to be fixed, or can be configured to allow the object 10 to be fixed to be coupled. The spherical joint 100, which can be a part of the object 10 to be fixed or can be coupled with the object 10 to be fixed, can include a spherical portion 110 formed in a spherical shape and an arm portion 120 formed in a rod shape and extending from the spherical portion 110. The spherical portion 110 can be provided inside the front end portion of the holding body A, and the arm portion 120 can be provided to penetrate the front end portion of the holding body A.

[0029] As shown in Figures 2 to 4 , the holding body A includes a fixed pressurizing member 200, an elastic member 300, and a fixed controller 400 inside thereof, configured to be able to control the movement of the spherical portion 110.

[0030] The fixed pressurizing member 200 is provided at the rear portion of the spherical portion 110 so as to be able to come into contact with the spherical portion 110, and is able to move inside the holding body A according to the elastic force of the elastic member 300, and is able to come into contact with the spherical portion 110 when moving toward the front. In one example, the front end portion of the fixed pressurizing member 200 which directly contacts the spherical portion 110 can be formed in a semispherical shape, so that the spherical portion 110 can be stably seated. In another example, as shown in Figures 2 to 4 , the fixed pressurizing member 200 can include a cylindrical member 210 formed in a "C" shape having an end surface open toward the rear or formed in a tubular shape open toward the front and the rear, and a spherical housing 220 coupled to the front end portion of the cylindrical member 210 and having a semispherical shape at the front end portion to receive a portion of the spherical portion 110.

[0031] The elastic member 300 which is able to move the fixed pressurizing member 200 forward by the elastic force can be formed of various types of springs. For example, as shown in Figure 3 and Figure 4 , the elastic member 300 can be formed of a helical compression spring, the elastic member 300 being configured to have a front end portion which abuts against the cylindrical member 210 and a guard portion 410 which will be described later, and a rear end portion which abuts against the rear cover a3. In this case, the inner diameter of the rear end portion of the fixed pressurizing member 200, that is, the rear end portion of the cylindrical member 210 is preferably formed to be larger than the inner diameter of the front end portion of the elastic member 300, and the diameter of the guard portion 410 is preferably formed to be larger than the inner diameter of the front end portion of the elastic member 300.

[0032] The fixed controller 400 is configured to retract or extend the elastic member 300. In one example, as shown in Figures 2 to 4As shown in FIG. 1, the fixed controller 400 can include a guard portion 410 that is movable in forward and rearward directions within the cylindrical member 210 forming the fixed pressing member 200 and abuts against a front end portion of the elastic member 300, and a control rod 420 that extends rearward from the guard portion 410 to penetrate the elastic member 300 and is threadedly coupled to a rear end portion of the holding body A.

[0033] Specifically, the guard portion 410 can be formed in the shape of a plate or a cylinder having a circular or polygonal cross-section, and has an outer end portion configured to be positioned between the outer diameter and the inner diameter of the elastic member 300. The guard portion 410 is rotatable in contact with the front end portion of the elastic member 300, and a thrust bearing can be provided at a rear end portion to enable smooth rotation while reducing friction with the elastic member 300. The control rod 420 is formed in the shape of a rod having a diameter smaller than the inner diameter of the elastic member 300, and is provided with a thread on an outer peripheral surface to be threadedly coupled with a rear cover a3 constituting the rear end portion of the holding body A. In addition, a portion of the control rod 420 positioned on the outer side portion of the holding body A can be configured to be linked with a motor (not shown) to facilitate rotation of the control rod 420.

[0034] The fixed controller 400 can be axially rotated about a longitudinal axis of the control rod 420, which is an axis extending in the forward and rearward directions. As the fixed controller 400 is rotated, the length of the elastic member 300 is adjusted and the fixed pressing member 200 is moved, thereby fixing or releasing the spherical portion 110 or adjusting the fixing force on the spherical portion 110. In other words, the elastic member 300 can be retracted or extended depending on the direction in which the fixed controller 400 is axially rotated, and the fixing force of the spherical portion 110 can be adjusted by changing the degree to which the fixed controller 400 is axially rotated such that the fixed pressing member 200 presses the spherical portion 110.

[0035] Specifically, as shown in (a) of FIG. 2, when the control rod 420 is rotated in a direction of movement toward the rear, the elastic member 300 is retracted by the guard portion 410, which causes the fixed pressing member 200 to lose contact with the spherical portion 110. In this case, the spherical portion 110 is freely moved, thereby allowing the user to manipulate the fixed object 10 to reach a desired position and angle. Figure 5

[0036] In the case where the contact between the fixed pressing member 200 and the spherical portion 110 is released as described above, as shown in (b) of FIG. 2, when the control rod 420 is rotated in a direction of movement toward the front, the elastic member 300 is extended by the guard portion 410, which causes the fixed pressing member 200 to come into contact with the spherical portion 110. In this case, the spherical portion 110 is fixed, thereby preventing the user from manipulating the fixed object 10 to reach a desired position and angle. Figure 5 ​As shown in (b), the rotation of the control lever 420 shown moving forward causes the elastic member 300 to be elongated in proportion to the amount of movement of the guard portion 410, and the force (elasticity) transmitted by the elastic member 300 causes the fixed pressurizing member 200 to press the spherical portion 110 while being engaged with the spherical portion 110. In this case, the movement of the spherical portion 110 is restricted, so that the fixed object 10 can be fixed at a specific position at a specific angle.

[0037] When the control lever 420 is slightly rotated in a direction of moving toward the rear as shown in (b) while the elastic member 300 is in the extended state, Figure 6 the front end portion of the elastic member 300 having a larger outer diameter than the guard portion 410 is bent by the downward force applied by the slight movement of the guard portion 410. In this case, by moving the fixed object 10 in a state where the fixing force on the spherical portion 110 is slightly reduced (e.g., 30%, 50%, 70%, etc. of the maximum fixing force), it is possible to adjust the position and angle of the fixed object 10.

[0038] The holding body A can further include an auxiliary elastic member 500 provided inside the fixed pressurizing member 200 in front of the fixing controller 400 and having elasticity. In one example, as shown in (b), Figure 7 the auxiliary elastic member 500 can be formed of a compression spring having a smaller elastic force than the elastic member 300, and can be positioned inside the cylindrical member 210 in front of the guard portion 410, and can be elastically actuated in the forward and rearward directions. This auxiliary elastic member 500 prevents sudden release of the fixed state and facilitates precise control of the fixing force.

[0039] In other words, the auxiliary elastic member 500 is in a state where the front end portion is elastically supported on the cylindrical member 210 and the rear end portion is supported on the guard portion 410. Therefore, since the auxiliary elastic member 500 pushes the cylindrical member 210 with an elastic force, even if the control lever 420 is rotated in a direction of moving toward the rear while the elastic member 300 is in the extended state, the spherical portion 110 is not suddenly released from the fixed state, and fine adjustment of the fixing force can be more smoothly performed. Furthermore, due to the auxiliary elastic member 500, it is possible to perform fixing force adjustment of the spherical portion 100 regardless of the direction of the front end portion of the holding body A having the spherical joint 100.

[0040] In addition, the holding body A can further include an adjustment guide plate 600 provided at the front end portion of the elastic member 300, on which the rear end portion of the fixed pressurizing member 200 and the guard portion 410 are abutted. In one example, as shown in (b), Figure 8As shown in the middle, the adjustment guide plate 600 can be formed in a ring shape corresponding to the cross section of the elastic member 300, and can be bent when finely adjusting the fixing force. This is to prevent the elastic force from being affected when the front end of the elastic member 300 is in direct contact with the guard portion 410 and continuously bent.
