The present invention relates to a bearing, particularly a surgical tool applicable to minimally invasive surgery.

In existing surgeries, suturing instruments, such as clamps or tweezers, are inserted into the patient's body through an opening on the patient's skin to perform suturing. In recent years, in order to shorten the recovery period of surgical patients and reduce the opening on the patient's skin, minimally invasive surgery has gradually become popular. However, since the opening of minimally invasive surgery is very small, it is difficult for existing surgical instruments to be inserted into the patient's body for suturing. Therefore, it is necessary to provide a surgical tool that can penetrate into the patient's body and cooperate with minimally invasive surgery to meet the needs of minimally invasive surgery.

The present invention mainly provides a surgical tool. Please refer to Figures 1 to 3. It can be seen from the figures that the surgical tool of the present invention includes a handle portion 10, a long tube portion 20 and a clamping portion 30. The handle portion 10 can be held by the operator. The handle portion 10 can be a hollow one-piece structure as shown in the figure, or can be composed of two pivotal handles. The long tube portion 20 is connected to the handle portion 10, and the clamping portion 30 is arranged on the long tube portion 20 and is different from being connected to the handle portion 10. At one end, the clamping part 30 includes a hook 32 and a closing part 34. The hook 32 can be fixedly connected to the long tube part 20, and the end of the hook extends toward the bend of the handle part and is formed to face an opening direction of the handle part. The closing part 34 is connected to the hook 32 in a pivotal manner. When the closing part 34 pivots relative to the hook 32, the closing part 34 can open or close the hook 32 relative to loosen or clamp the suture to perform surgical suture operations.

In order to control the pivoting opening and closing of the closing member 34, the surgical instrument of the present invention is further provided with a control mechanism 40. Please refer to Figures 2 to 4. The control mechanism 40 is provided on the handle portion 10 and extends through the long tube portion 20 to be connected to the closing member 30 to control the pivoting of the closing member 34 relative to the hook 32, so that the clamping portion 30 switches between an open state and a closed state. As shown in Figure 7, in the open state, the end of the closing member 30 is located between the hook 32 and the end of the hook 32; and in the closed state, the end of the closing member 30 is aligned with the end of the hook 32, and the closing member 30 and the hook 32 together form a closed space.

The control mechanism 40 may include an actuating member 42, a connecting member 44 and a connecting rod 46. The actuating member 42 is movably disposed in the handle portion 10. The actuating member 42 is provided with an actuating ring 422 exposed outside the handle portion 10. The actuating member 42 is provided with an actuating shaft 424 protruding from the actuating member 42. The connecting member 44 is movably disposed in the handle portion 10 and can be relatively movably disposed. It is sleeved on the starting shaft 424 of the starting member 42, and a long groove 442 is provided on one end of the connecting member 44 near the starting member 42, and the starting shaft 424 on the starting member 42 is movably inserted into the long groove 442. The connecting rod 46 is movably arranged to penetrate the long tube part 20, and one end of the connecting rod 46 is pivotally connected to the connecting member 44 different from the end connected to the starting member 42. The other end of the connecting rod 46 is pivotally connected to one end of the closing member 34.

Thus, when the operator hooks the start ring 422 with his finger, he pulls the start ring 422 to move the start member 42 relative to the handle 10, thereby allowing the start shaft 424 to move relative to the long slot 442 of the connecting member 44, causing the connecting member 44 to deflect, thereby driving the connecting rod 46 to move relative to the long tube 20, and finally, the closing member 34 can be moved relative to the hook 32 through the movement of the connecting rod 46. The hinge forms a closed space between the hook 32 and the closing member 34, and the clamping portion 30 is in a closed state, as shown in FIG6. When the actuating member 42 is moved back, the closing member 34 can be pivoted in the opposite direction through the actuating member 42, the connecting member 44 and the connecting rod 46, and the space between the hook 32 and the closing member 34 is opened, so that the clamping portion 30 is in an open state, as shown in FIG7.

Therefore, during operation, the clamping part 30 and the long tube part 20 can be inserted into the patient's body through the minimally invasive surgery incision on the patient's skin, and the hook 32 in the open state can be used to hook the suture. The operator can then manipulate the suture through the handle 10 outside the patient's body to perform suture or knotting operations, and then pull the starter. The ring 422 pivots the closing member 34 to form a closed space between the hook 32 and the closing member 34, so that the suture is separated from the hook 32, and then the hook 32 is repeatedly opened or closed to cooperate with different suture operations of the suture, so that the operator can control the suture through the handle 10 outside the patient's body to perform surgical suture operations.

In addition, in order to make the actuating member 42 move more smoothly relative to the grip portion 10, please refer to FIG. 4 and FIG. 6. A guide rod portion 426 may be protruded on the actuating member 42, and a track portion 12 is formed in the grip portion 10 so that the guide rod portion 426 can be movably inserted therein. In this way, the actuating member 42 can move smoothly forward or backward relative to the grip portion 10 by the mutual cooperation of the track portion 12 and the guide rod portion 426. 0 can be provided with an elastic member against the starter member 42, and the elastic member can provide the starter member 42 with a force to automatically move back, so that the operator can release the starter ring 422 after pulling the starter ring 422, and the starter member 42 can be automatically moved back by the elastic member, so that the closing member 34 can be reversely pivoted to open the space between the hook member 32 and the closing member 34. The elastic member can be a set of springs provided on the guide rod part 426.

Furthermore, please refer to FIG. 2, FIG. 4 and FIG. 5, the control mechanism 40 may further include a clamping member 50, which is movably disposed on the handle portion 10, and the top surface of the clamping member 50 is convexly provided with a pressing portion 52 exposed to the outside of the handle portion 10, and a clamping hole 54 is provided on the clamping member 50, and the clamping hole 54 is in an inverted L shape and has a horizontal portion 542 and a clamping portion 544 formed at one end of the horizontal portion 542, and A locking shaft 428 is protruded from the actuating member 42 and can be movably extended into the horizontal portion 542 of the locking hole 54. In this way, when the closing member 34 is in an open state relative to the hook member 32, the locking shaft 428 on the actuating member 42 can be opposite to the locking portion 544 of the locking hole 54. At this time, the locking member 50 is moved upward, and the locking shaft 428 can be locked in the locking portion 544 of the locking hole 54. In this way, the operator cannot pull the actuating ring 422, and the closing member can be locked. 34 is kept in an open state relative to the hook 32, so that the hook 32 of the clamping portion 30 can stably hook the suture. When the closing member 34 is to be closed relative to the hook 32, the pressing portion 52 of the clamping member 50 is pressed downward, so that the clamping shaft 428 on the starting member 42 can leave the clamping portion 544 of the clamping hole 54 and face the horizontal portion 542. The operator can pull the starting ring 422 relative to the grip portion 10 to drive the closing member 34 to pivot. In turn, the space formed by the closing member 34 and the hook member 32 is in a closed state. In addition, an elastic member can be provided in the handle portion 10 to abut against the bottom of the clamping member 50, so that when the clamping shaft 428 on the starting member 42 is opposite to the clamping portion 544 of the clamping hole 54, it is kept in a position clamped with the clamping portion 544, so that when the stitching thread is operated through the handle portion 10 for sewing, the clamping portion 30 will not be loosened arbitrarily, so that the sewing operation can be more smooth.

It can be seen from the above content that different modifications and changes can be achieved without departing from the spirit and novel concepts of the present invention, and the specific embodiments disclosed in the present invention are not intended to limit the present invention. This disclosure includes all modifications that fall within the scope of the attached patent application.
