For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0065] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0066] The medical device clamping device provided in this embodiment is as follows: Figure 1 As shown, it includes: a clamp 1, a rocker arm 2 and a base 3; the device clamps the medical device 4 through the clamp 1 and clamps it on the operating table through the base 3; because the rocker arm 2 is connected by a connecting ball 21 and a joint, when the connecting rope is in a loose state, the connecting ball 21 and the joint can be rotated at will, and the rocker arm 2 can be adjusted to various directions. When the connecting rope is in a tightened state, the connecting ball 21 and the inner and outer surfaces of the joint rub against each other, and the friction between the connecting ball 21 and the joint causes the state of the rocker arm 2 to be locked and in a clamping state; during the operation, the clamping device can firmly clamp the medical device 4, reducing the burden on the hands of medical staff; and the medical device 4 can be adjusted to any angle, and the transformation is flexible, so that the medical staff can transport the medical device 4 to the target position.
[0067] like Figure 2As shown, the clamp 1 is connected to the rocker arm 2 via a connecting mechanism; the clamp 1 is connected to the connecting mechanism via a fastener 5, so the clamp 1 can be quickly replaced according to different medical devices 4.
[0068] like Figure 3 As shown, the clamp 1 includes an upper clamp 6 and a lower clamp 7; the upper clamp 6 and the lower clamp 7 are fixed together by a fastening bolt 10; the shapes of the upper clamp 6 and the lower clamp 7 are adapted to the device, so different upper clamps 6 and lower clamps 7 can be designed according to the shapes of different medical devices 4;
[0069] like Figure 4 , 5 As shown, the front end of the rocker arm 2 is provided with a front connection joint 8, and the front connection joint 8 has a through cavity, one end of the cavity is a fourth arc-shaped concave surface 12, which is matched and connected with the connection ball 21; the other end has a second annular concave edge 11;
[0070] like Figure 6 , 7 As shown, a driving member 14 is slidably disposed in the front connecting joint 8, and an abutting pressure head 16 is slidably disposed crosswise with the driving member 14. The driving member 14 and the abutting pressure head 16 form a second accommodating cavity, and a pulling rod 18 with a spherical end is slidably disposed in the second accommodating cavity;
[0071] like Figure 8 As shown, the structure of the driving member 14 is shown, one end of the driving member 14 has a protruding end 15, and the other end is a ring structure;
[0072] like Fig. 9 As shown, the structure of the abutting pressure head 16 is shown. One end of the abutting pressure head 16 has an abutting surface, and the other end of the abutting pressure head 16 has a first annular flange 17; the first annular flange 17 abuts against the second annular recess 11 of the front connecting joint 8;
[0073] like Fig.10 As shown, it is a schematic diagram of the structure in which the driving member 14 and the abutting pressure head 16 are connected in cooperation; the abutting pressure head 16 and the driving member 14 are arranged to slide crosswise; and the abutting pressure head 16 and the driving member 14 cooperate to form a second accommodating cavity;
[0074] A pulling rod 18 is slidably arranged in the second accommodation cavity, one end of the pulling rod 18 is spherical, and the other end is a straight rod; the spherical end of the pulling rod 18 is slidably arranged in the second accommodation cavity formed by the abutting pressure head 16 and the driving member 14, and is limited in the second accommodation cavity by the annular structure, and the straight rod end of the pulling rod 18 extends out of the second accommodation cavity and is connected to the connecting rope;
[0075] The front end of the abutting surface of the abutting pressure head 16 abuts against a spherical straight rod 13 , one end of the spherical straight rod 13 is connected to a rotating ball, and the other end of the straight rod is connected to the clamp 1 .
[0076] like Fig.11 As shown, the outer surface of the rotating ball of the spherical straight rod 13 is sleeved with a housing 9;
[0077] like Fig.12 As shown, the shell 9 has a through first accommodating chamber 20, and the rotating ball of the spherical straight rod 13 is rotatably arranged at one end of the first accommodating chamber 20. At the same time, a notch is provided on the shell 9 at this end. The opening of the notch increases the adjustment range of the angle between the clamp 1 and the shell 9; a first annular recess 19 is provided at the other end of the first accommodating chamber 20, and the protruding end 15 of the driving member 14 is clamped with the first annular recess 19; the first annular flange 17 of the first pressure head abuts against the outer side of the first accommodating chamber 20 of the shell 9.
[0078] During use, the other end pulls the connecting rope, and the connecting rope pulls the traction rod to move, and the spherical end of the traction rod drives the driving member 14 to move, and the driving member 14 pulls the shell 9 to move, so that the inner wall of the shell 9 abuts against the spherical end of the spherical straight rod 13; at the same time, due to the action of the rear end rocker arm 2, the front connecting joint 8 moves a certain position toward one end of the clamp 1, pushing the abutment pressure head 16 to move, so that the abutment surface of the abutment pressure head 16 abuts against the spherical end of the spherical straight rod 13; under the action of the inner wall of the first accommodating cavity 20 of the shell 9 and the abutment surface of the abutment pressure head 16, the rotating ball of the spherical straight rod 13 cannot rotate, thereby realizing the relative fixation of the angle of the clamp 1 and the rocker arm 2.
[0079] like Fig.13 , 14 As shown, it is a part of the rocker arm 2, which is composed of a plurality of connecting balls 21 and a plurality of joints connected in sequence at intervals; there are through holes inside the connecting balls 21 and the joints, and a connecting rope is passed through the through holes; one end of the connecting rope is connected to the clamp 1, and the other end is connected to the handle assembly; the diameter of the rocker arm 2 gradually decreases from one end of the base to one end of the clamp 1, therefore, as the diameter of the rocker arm 2 decreases, the size of each connecting ball 21 and the joint also decreases regularly, but the internal structure is consistent.
[0080] like Fig.15 As shown, it is a three-dimensional structural diagram of the connecting ball 21; the connecting ball 21 has two second arc-shaped concave surfaces 23 on the oppositely arranged surfaces; and the connecting ball 21 has a second through hole 25 inside;
[0081] like Fig.16As shown, it is a three-dimensional structural diagram of the joint 22; a first arc-shaped concave surface 24 is provided at both ends of the joint 22, and the first arc-shaped concave surface 24 matches the diameter of the adjacent connecting ball 21; the connecting ball 21 rotates in the first arc-shaped concave surface 24; and a first through hole 26 is provided inside the joint 22.
[0082] The first through hole 26 and the second through hole 25 are connected and correspondingly arranged; a connecting rope is passed through them; when the connecting rope is in a relaxed state, the surfaces of the connecting ball 21 and the joint are in contact with each other and their shapes are adapted to each other, so the rocker arm 2 composed of the connecting ball 21 and the joint can rotate in a random direction; when the connecting rope is tightened, the connecting ball 21 and the joint are squeezed against each other to provide sufficient friction to fix the rocker arm 2 and lock the medical device 4.
[0083] Furthermore, the connecting ball 21 and the joint can be made of high molecular polymer materials or metals, such as stainless steel; and the contact surfaces of the connecting ball 21 and the joint have patterns or other treatments to increase surface friction.
[0084] like Fig.17 As shown, one end of the rocker arm 2 is connected to a rear connection joint 27, and the rear connection joint 27 has a through cavity inside, and a rotating component is arranged inside the cavity; the other end of the rear connection joint 27 is connected to a handle component;
[0085] like Fig.18 , 19 As shown, a handle body 28 is provided at one end of the rear connection joint 27. When the connection rope is in a relaxed state, there is a gap between the rear connection joint 27 and the handle body 28. A third accommodating cavity 32 is provided inside the handle body 28. A threaded connector 36 is connected to the inner wall of the third accommodating cavity 32. An internal thread is provided inside the threaded connector 36. A sliding block 33 is threadedly connected inside the internal threaded connector 36. The sliding block 33 is connected to the connection rope.
[0086] The end of the handle body 28 is fixedly connected to one end of a push block 34, wherein the push block 34 has a through cavity, and a fourth accommodating cavity 35 is provided at one end of the cavity close to the handle, and one end of the sliding block 33 can slide into the fourth accommodating cavity 35; the side wall of the threaded connector 36 abuts against the end face of the push block 34; the other end of the push block 34 is provided with an inclined surface;
[0087] like Fig. 20 As shown, a connecting ring 37 is sleeved on the upper of the push block 34. Specifically, the connecting ring 37 has an abutment hole, and one end of the abutment hole has an upper that matches the upper of the push block 34.
[0088] The lower end of the connecting ring 37 is rotatably connected to the base; the upper end of the base has an arc-shaped surface, which is matched and connected with the third arc-shaped concave surface at the lower end of the rear connecting joint 27;
[0089] When it is necessary to tighten the connecting rope, the handle body 28 is rotated to drive the threaded connecting piece 36 to move and rotate relative to the sliding block 33; since there is a certain gap between the handle body 28 and the rear connecting joint 27, the handle body 28 will move toward the rear connecting joint 27 and the sliding block 33 will move away from the rear connecting joint 27 while the handle is rotated; the movement of the sliding block 33 tightens the connecting rope and fixes the direction of the clamp 1 of the rocker arm 2; and the movement of the handle body 28 drives the push block 34 to move, and the forward movement of the push block 34 causes the connecting ring 37 to move upward, driving the base to move upward, so that the base and the rear connecting joint 27 abut against each other and can no longer rotate relative to each other, thereby achieving relative fixation of the position of the base.
[0090] The base includes an upper base 29 and a lower base 30 connected to the upper base 29 via a fastening knob 31; the upper base 29 and the lower base 30 clamp the operating table or other plane like a sandwich, so that the entire clamping device is positioned.
[0091] Usage and principle
[0092] The size of the clamp 1 is selected according to the size of the medical device 4, and is fixedly connected to the spherical straight rod 13 through the fastener 5; the clamping device is fixed on the operating table or other plane by clamping the upper base 29 and the lower base 30;
[0093] The connecting rope is in a loose state, and the medical device 4 is adjusted to a suitable angle. After the angle is determined, the handle body 28 is rotated to tighten the connecting rope, so that the clamp 1, the rocker arm 2 and the base are fixed. The connecting rope plays the role of locking and connecting the components.
[0094] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
