[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0020] like Figure 1-3 As shown, an embodiment of the utility model provides a chuck assembly of a soft tissue clamp that is easy to replace, comprising: a chuck 1 and a hand-held part 2;

[0021] The chuck 1 comprises a clamping portion 3 and a mounting portion 4;

[0022] The sleeve part 5 is installed between the mounting part 4 and the hand-held part 2; the sleeve part 5 includes an outer sleeve 51 and a guide wire 52, the outer sleeve 51 is installed between the mounting part 4 and the hand-held part 2, the guide wire 52 is inserted inside the outer sleeve 51 and can slide and rotate freely, the two ends of the guide wire 52 are respectively connected to the mounting part and the hand-held part 2, and the bottom of the outer sleeve 51 is fixedly connected to the top of the fixing ring 43. The lengths of the outer sleeve 51 and the guide wire 52 are determined according to actual conditions.

[0023] The mounting portion 4 includes a ring plate 41 mounted on the top of the clamping portion 3, and a plurality of semicircular blocks 42 are fixedly mounted on the outer circumference of the ring plate 41 in a circular array. A fixing ring 43 is installed at the bottom of the sleeve portion 5, and a slot 44 is configured on the fixing ring 43. The ring plate 41 is inserted into the slot 44, and a plurality of grooves 45 are configured on the inner circumference of the slot 44, which correspond to the plurality of semicircular blocks 42 one by one, and the semicircular blocks 42 are snapped into the grooves 45. The grooves 45 are connected to the slots 44. The semicircular blocks 42 are medical soft plastics, which can be squeezed and deformed at a certain strength, and the surgical-level force will not cause the semicircular blocks 42 to move out of the grooves 45.

[0024] The chuck 1 is connected to the hand-held part 2 through the sleeve part 5, and the sleeve part 5 is composed of an outer sleeve 51 and a guide wire 52. The outer sleeve 51 is fixed between the mounting part 4 and the hand-held part 2, and the guide wire 52 is free to slide and rotate inside the outer sleeve 51. The two ends of the guide wire 52 are respectively connected to the mounting part 4 and the hand-held part 2, ensuring the flexibility and stability of operation. The mounting part 4 is connected to the clamping part 3 through a ring plate 41. A plurality of semicircular blocks 42 are distributed on the outer peripheral side of the ring plate 41. The semicircular blocks 42 are clamped with the grooves 45 on the fixing ring 43 to form a quickly detachable structure, allowing the sleeve part 5 to be separated, disassembled and replaced from the clamping part 3 to adapt to the replacement of clamping parts 3 of different shapes and sizes. A cylindrical magnet 6 is installed on the top of the clamping part 3, and a cylindrical iron block 7 is fixed on the top of the guide wire 52. The cylindrical magnet 6 and the cylindrical iron block 7 are fixed by magnetic connection. The cylindrical magnet 6 is a strong magnet. When the guide wire 52 rotates to drive the cylindrical iron block 7 to rotate, the clamping part 3 can rotate synchronously, thereby facilitating the rotation angle of the clamping part 3, facilitating the clamping of soft tissues in different directions, and realizing precise control of the chuck 1. The clamping part 3 can be replaced by the hand-held part 2, and the clamping part 3 can be replaced by the hand-held part 2.

[0030] The bottom of the fixing ring 43 fits tightly with the top of the clamping part 3 to avoid a gap between the two. During surgery, soft tissue may enter the gap and cause pulling, which may affect the surgical effect.

[0031] like Figure 2 As shown, in some embodiments, the outer circumference of the fixing ring 43 is configured with anti-slip textures.

[0032] When replacing the chuck 1 , the anti-skid pattern can facilitate identification of the position of the mounting portion 4 , making it convenient for the staff to pull and replace the chuck 1 .

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
