[0044] S4. When there is no need to clamp the tissue, the operator maintains the height of the push block relative to the connecting ring and pushes the push block toward the direction of the second clamp handle with the thumb. The push block drives the connecting column one to move inside the second clamp handle by means of sliding cooperation between the lifting plate and the mounting seat and movable abutment between the connecting ring and the limit ring. The connecting column one drives the engaging column away from the first clamp handle by driving the movable rod to move synchronously.

[0045] In summary, compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0046] 1. In the present invention, the operator holds the pliers handle and puts the little finger through the finger ring. Since the adjustment component is connected to the movable rod, and the movable rod is connected to the pliers head through the transmission component, the operator increases or decreases the angle between the symmetrically arranged pliers heads by pushing the adjustment component forward or backward, which can meet the clamping requirements in different situations. When the angle between the symmetrically arranged pliers heads becomes smaller, the tissue can be stably clamped, and at the same time, the bleeding site can be clamped to provide the doctor with a surgical field of view for cleaning. In addition, by clamping the tissue, it can help the doctor to separate the lesion area and perform other necessary surgical operations. By controlling the state of the switching component, the working state of the adjustment component can be adjusted, and the angle adjustment and rotation of the pliers head can be realized, which is convenient for comprehensive and efficient cleaning of the surface of the pliers head and avoids the blind spots that may exist in manual cleaning.

[0047] 2. In the present invention, when it is necessary to clamp the tissue, the operator presses the push block into the inside of the clamp handle with his thumb, and the push block drives the lifting plate to approach the connecting ring, the spring 2 is stressed and contracts, and the meshing between the limit rack and the fixed rack is released. When it is necessary to fix the angle of the clamp head after adjustment, the operator gradually lifts his thumb upward, the spring 2 extends upward and pushes the lifting plate away from the connecting ring, the lifting plate drives the push block to move upward synchronously, and the lifting plate drives the limit rack to move upward synchronously, so that the limit rack is meshed with the fixed rack at the corresponding position, thereby realizing the fixation of the position of the connecting column, and then realizing the fixation of the angle of the clamp head after adjustment, so that the tissue can be stably clamped, which meets the positioning requirements of the clamp head at different angles, and is convenient for the operator to clamp tissues of different specifications. At the same time, it avoids the existing manual continuous force required to stably clamp the tissue, thereby reducing the burden on the operator;

[0048] 3. In the present invention, by setting the switching component, the lever is pushed downward, and the lever drives the rotating drum to rotate 90 degrees around the axis of the rotating drum. The rotating drum drives the movable seat and the connecting column 2 to approach the connecting column 1 by sliding cooperation between the spiral groove and the spiral piece 2 and the through hole and the cross bar, so that the abutment column and the spiral piece 1 slide together. The operator drives the connecting column to move back and forth in the axial direction of the clamp handle 1 through the adjustment component, and the connecting column realizes its own rotation by sliding cooperation between the abutment column and the spiral piece 1. The connecting column drives the pliers head to rotate by sliding cooperation between the movable rod and the pliers handle 2 and the movable cooperation between the pliers handle 2 and the pliers head. At the same time, the connecting column adjusts the angle of the pliers head by cooperating with the movable rod and the transmission component, thereby realizing the rotation and angle change of the pliers head, facilitating the rapid cleaning of the pliers head and avoiding the problem of blind spots that may exist in manual cleaning.

The clamp handle 1 is set as a cylinder with an opening on one side, and the clamp handle 2 is set as a cylinder with openings on both sides.

[0066] In one embodiment of the present invention, see Figure 1-Figure 3 The transmission assembly 5 includes a rotating column 52 which is symmetrically and rotatably arranged at the end of the clamp handle 2 2 away from the clamp handle 1 1. A sleeve 51 connected to the corresponding clamp head 3 is rotatably arranged on the rotating column 52. A toothed ring 53 is arranged on the outer side of the sleeve 51. An engaging column 54 is connected to the end of the movable rod 4 close to the clamp head 3. The engaging column 54 is located between the symmetrically arranged rotating columns 52 and meshes with the toothed ring 53.

[0067] In this embodiment, when it is necessary to clamp the tissue, the operator drives the movable rod 4 close to the clamp handle 1 through the adjustment component 6, and the movable rod 4 drives the engagement column 54 to move synchronously, and the engagement column 54 drives the outer ends of the symmetrically arranged clamp heads 3 to approach each other by engaging with the toothed ring 53 and rotating the sleeve 51 and the rotating column 52, thereby clamping the tissue;

[0068] The number of teeth on the gear ring 53 is consistent with the number of ring teeth on the engagement column 54 , so that precise engagement between the gear ring 53 and the engagement column 54 can be achieved.

[0069] In one embodiment of the present invention, see Figure 1-Figure 6, the adjusting assembly 6 includes a connecting column 1 61 movably arranged inside the clamp handle 1 and the clamp handle 2, one end of the connecting column 1 61 is connected to the end of the movable rod 4 away from the clamp head 3, the end of the connecting column 1 61 away from the movable rod 4 is provided with two limiting rings 63, and a spacing is provided between the two limiting rings 63, the connecting column 1 61 is movably sleeved with a connecting ring 64, the connecting ring 64 is located between the two limiting rings 63, and a mounting seat 65 is installed on the connecting ring 64, the clamp handle 1 is provided with a guide groove 68, and the guide groove 68 is parallel to the axis of the clamp handle 1, a lifting plate 66 slidably matched with the mounting seat 65 is movably provided in the clamp handle 1, a spring 2 611 is connected between the lifting plate 66 and the mounting seat 65, a push block 67 is installed at the end of the lifting plate 66 away from the mounting seat 65, and a limiting module is provided between the lifting plate 66 and the clamp handle 1;

[0070] The limiting module includes a limiting rack 610 arranged on the side wall of the lifting plate 66 and a fixed rack 69 arranged on the top inner side of the clamp handle 1, and the fixed rack 69 is movably engaged with the limiting rack 610.

[0071] In this embodiment, in the initial state, the spring 2 611 is at its original length, the lifting plate 66 and the push block 67 are away from the connecting ring 64, and the limiting rack 610 is engaged with the fixed rack 69. At this time, the angle between the symmetrically arranged clamp heads 3 is fixed;

[0072] When it is necessary to clamp the tissue, the operator presses the push block 67 with his thumb toward the inside of the clamp handle 1, and the push block 67 drives the lifting plate 66 to approach the connecting ring 64. The spring 2 611 is stressed and contracts, releasing the engagement between the limit rack 610 and the fixed rack 69. Then, the operator maintains the height of the push block 67 relative to the connecting ring 64 and moves the push block 67 away from the clamp handle 2 with his thumb. The push block 67 is engaged with the lifting plate 66 and the guide groove 68, and the lifting plate 66 and the mounting seat 65 are slidably engaged. The connection column 61 is driven to move toward the inside of the clamp handle 1 by the way of engagement and the movable contact between the connection ring 64 and the limit ring 63.

At the same time, it avoids the existing problem of manual continuous force on the clamp body to stably clamp the tissue, thereby reducing the burden on the operator;

[0074] When there is no need to clamp the tissue, the operator maintains the height of the push block 67 relative to the connecting ring 64 and pushes the push block 67 with the thumb in the direction close to the clamp handle 2. The push block 67 drives the connecting column 1 61 to move inside the clamp handle 2 by means of sliding cooperation between the lifting plate 66 and the mounting seat 65 and the movable contact between the connecting ring 64 and the limiting ring 63. The connecting column 1 61 drives the meshing column 54 away from the clamp handle 1 by driving the movable rod 4 to move synchronously. The meshing column 54 drives the outer ends of the symmetrically arranged clamp heads 3 away from each other by means of meshing with the toothed ring 53 and the rotation cooperation between the sleeve 51 and the rotating column 52, thereby increasing the angle between the symmetrically arranged clamp heads 3 and releasing the clamping operation of the tissue.

[0075] The push block 67 is an isosceles trapezoidal platform, and slots (not marked in the figure) are provided on both sides of the mounting seat 65. The size of the slots is larger than the size of the limit rack 610, so as to avoid interference between the lifting and lowering of the limit rack 610 and the side wall of the mounting seat 65, thereby improving the working stability of the device.

[0076] The limiting module can also be configured as a first wedge block and a second wedge block that are movably fitted to each other, the first wedge block being arranged on the side wall of the lifting plate 66, the second wedge block being arranged at the inner top of the pliers handle 1 and corresponding to the first wedge block, the inclined surface of the first wedge block corresponding to the inclined surface of the second wedge block, the inclined surfaces of the first wedge block and the second wedge block are both configured as rough surfaces, when the angle of the pliers head 3 is fixed, the spring 2 611 is at its original length, the inclined surface of the first wedge block abuts against the inclined surface of the second wedge block, the positioning between the first wedge block and the second wedge block can be realized, thereby fixing the angle of the pliers head 3.

[0077] In one embodiment of the present invention, see Figure 1-Figure 9The switching assembly 7 includes a side plate 71 arranged at one end of the clamp handle 1 near the clamp handle 2, and a slide groove 72 perpendicular to the length direction of the clamp handle 1 is provided on the side plate 71. A rotating cylinder 73 that penetrates the clamp handle 1 is rotatably provided on the side plate 71, and a lever 74 is provided on the outer side of the rotating cylinder 73. A through groove 75 is provided on the lever 74, and a connecting rod 76 is provided in the through groove 75. A sliding seat 78 that slides and cooperates with the slide groove 72 is slidably provided on the connecting rod 76. A spring 77 sleeved on the outer side of the connecting rod 76 is connected between the through groove 75 and the sliding seat 78. The rotating cylinder 73 near the clamp handle 1 is provided with a spring 77. A spiral groove 731 is spirally provided inside the end, a movable seat 79 is movably provided in the clamp handle 1, and a through hole 791 is provided on the movable seat 79. A cross bar 710 connected to the inner wall of the clamp handle 1 is slidably provided in the through hole 791, and an abutment column 711 movably cooperates with the spiral piece 1 62 is provided at one end of the movable seat 79 close to the connecting column 1 61, and a connecting column 2 792 is provided at one end of the movable seat 79 away from the spiral piece 1 62. The connecting column 2 792 is movably provided inside the rotating drum 73, and a spiral piece 2 793 slidably cooperates with the spiral groove 731 is spirally provided on the outer side of the connecting column 2 792.

[0078] In this embodiment, in the initial state, the sliding seat 78 is located at the upper end of the slide groove 72, the spring three 77 is at the original length, and the abutment column 711 is away from the connecting column one 61, so that the initial angle of the lever 74 can be fixed. At this time, the clamp handle two 2 does not rotate, and the symmetrically arranged clamp head 3 can only adjust the angle;

[0079] When it is necessary to clean the pliers head 3, the lever 74 is pushed downward, and the lever 74 drives the rotating drum 73 to rotate 90 degrees around the axis of the rotating drum 73. In the process of the lever 74 rotating downward from the inclined state to the horizontal state, the lever 74 drives the sliding seat 78 to move closer to the rotating drum 73 through the sliding cooperation between the connecting rod 76 and the sliding seat 78 and the sliding cooperation between the sliding seat 78 and the sliding groove 72. At this time, the spring three 77 is forced to shrink and shrink to the shortest. In the process of the lever 74 rotating downward from the horizontal state to the inclined state, the spring three 77 extends and pushes the sliding seat 78 is away from the rotating cylinder 73. When the sliding seat 78 is located at the lower end of the sliding groove 72, the spring three 77 returns to its original length, thereby fixing the angle of the lever 74 after rotation. In the process of the sliding seat 78 moving from the upper end of the sliding groove 72 to the lower end of the sliding groove 72, the rotating cylinder 73 rotates 90 degrees. The rotating cylinder 73 drives the moving seat 79 and the second connecting column 792 to approach the first connecting column 61 through the sliding cooperation between the spiral groove 731 and the second spiral piece 793 and the sliding cooperation between the through hole 791 and the cross bar 710.

[0080] Next, the operator presses the push block 67 toward the inside of the clamp handle 1 with his thumb, and the push block 67 drives the lifting plate 66 to approach the connecting ring 64. The spring 2 611 is stressed and contracts, releasing the meshing between the limit rack 610 and the fixed rack 69. Then, the operator maintains the height of the push block 67 relative to the connecting ring 64 and uses his thumb to move the push block 67 back and forth in the length direction of the guide groove 68. The push block 67 drives the connecting ring 64 to reciprocate inside the clamp handle 1 by means of the movable cooperation between the lifting plate 66 and the guide groove 68, the sliding cooperation between the lifting plate 66 and the mounting seat 65, and the movable abutment between the connecting ring 64 and the limiting ring 63. At the same time, since the position of the abutment column 711 is fixed, the abutment column 711 and the spiral sheet 1 are in sliding cooperation, and the connecting ring 64 and the connecting column 1 are in movable cooperation, the connecting ring 64 drives the connecting column 1 to reciprocate inside the clamp handle 1, and the connecting column 1 61 realizes reciprocating rotation by means of the sliding cooperation between the spiral sheet 1 62 and the abutment column 711.

[0081] Specifically, when the connecting ring 64 drives the connecting column 161 to move inside the clamp handle 1, the connecting column 161 realizes its own clockwise rotation by means of the sliding cooperation between the spiral sheet 162 and the abutting column 711, and the connecting column 161 drives the movable rod 4 to rotate synchronously clockwise, and the movable rod 4 drives the clamp handle 22 to rotate synchronously by means of the sliding cooperation between the convex strip 41 and the fixed ring 21, and the clamp handle 22 drives the clamp head 3 to rotate synchronously, and at the same time, the connecting column 161 drives the engaging column 54 to move synchronously by driving the movable rod 4 to move inside the clamp handle 1, and the engaging column 54 drives the outer ends of the symmetrically arranged clamp head 3 to approach each other by means of the engagement with the toothed ring 53 and the rotation cooperation between the sleeve 51 and the rotating column 52, so that the rotation of the clamp head 3 and the reduction of the angle can be realized;

[0082] When the connecting ring 64 drives the connecting column 61 to move outside the clamp handle 1, the connecting column 61 realizes its own counterclockwise rotation by means of the sliding cooperation between the spiral sheet 62 and the abutting column 711, and the connecting column 61 drives the movable rod 4 to rotate counterclockwise synchronously, and the movable rod 4 drives the clamp handle 22 to rotate synchronously by means of the sliding cooperation between the convex strip 41 and the fixed ring 21, and the clamp handle 22 drives the clamp head 3 to rotate synchronously. At the same time, the connecting column 61 drives the engaging column 54 to move synchronously by driving the movable rod 4 to move outside the clamp handle 1, and the engaging column 54 drives the outer ends of the symmetrically arranged clamp head 3 to move away from each other by means of the engagement with the toothed ring 53 and the rotation cooperation between the sleeve 51 and the rotating column 52, so that the rotation of the clamp head 3 and the expansion of the angle can be realized;

[0083] The reciprocating rotation of the clamp head 3 and the reciprocating adjustment of the angle of the clamp head 3 facilitate the full contact between the clamp head 3 and the cleaning liquid, thereby avoiding the blind spots that may exist in manual cleaning and improving the cleaning effect.

[0084] In one embodiment of the present invention, see Figure 1-Figure 10A method for using an antibacterial tissue forceps is applicable to the antibacterial tissue forceps described above, and the method comprises the following steps:

[0085] S1. The outer end of the lever 74 is adjusted to the side close to the rotating cylinder 73 and the push block 67. The operator holds the clamp handle 1 and puts the little finger through the finger ring 11. The operator presses the push block 67 into the inside of the clamp handle 1 with the thumb. The push block 67 drives the lifting plate 66 to approach the connecting ring 64. The spring 2 611 is stressed and contracts, and the engagement between the limit rack 610 and the fixed rack 69 is released.

[0086] S2, the operator keeps the height of the push block 67 relative to the connecting ring 64 and uses the thumb to move the push block 67 in the direction away from the clamp handle 2, and the push block 67 drives the connecting column 1 61 to move inside the clamp handle 1 by means of the movable cooperation between the lifting plate 66 and the guide groove 68, the sliding cooperation between the lifting plate 66 and the mounting seat 65, and the movable contact between the connecting ring 64 and the limit ring 63. The connecting column 1 61 drives the meshing column 54 to approach the clamp handle 1 by driving the movable rod 4 to move synchronously, and the meshing column 54 drives the outer ends of the symmetrically arranged clamp heads 3 to approach each other by means of meshing with the toothed ring 53 and the rotational cooperation between the sleeve 51 and the rotating column 52, so as to clamp the tissue;

[0087] S3, the operator gradually lifts up his thumb, the spring 2 611 extends upward and pushes the lifting plate 66 away from the connecting ring 64, the lifting plate 66 drives the push block 67 to move upward synchronously, and the lifting plate 66 drives the limit rack 610 to move upward synchronously, so that the limit rack 610 is meshed with the fixed rack 69 at the corresponding position, so as to fix the position of the connecting column 1 61, and then fix the angle of the adjusted clamp head 3, so as to stably clamp the tissue;

[0088] S4. When there is no need to clamp the tissue, the operator maintains the height of the push block 67 relative to the connecting ring 64 and pushes the push block 67 in the direction close to the clamp handle 2 with the thumb. The push block 67 drives the connecting column 61 to move toward the inside of the clamp handle 2 by means of the sliding cooperation between the lifting plate 66 and the mounting seat 65 and the movable abutment between the connecting ring 64 and the limiting ring 63. The connecting column 61 drives the engaging column 54 away from the clamp handle 1 by driving the movable rod 4 to move synchronously. The engaging column 54 drives the outer ends of the symmetrically arranged clamp heads 3 away from each other by means of the engagement with the toothed ring 53 and the rotational cooperation between the sleeve 51 and the rotating column 52, thereby increasing the angle between the symmetrically arranged clamp heads 3 and releasing the clamping operation of the tissue.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
