Description

Technical Field

[0001] The present invention relates to the field of medical instruments, in particular to a special tissue grasping forceps with an adjustable suction device for use in breast laparoscopic surgery. Background Art

[0002] The existing double-jointed tissue grasping forceps used in laparoscopic breast surgery are used in laparoscopic surgery. The instrument has a short working head, a small opening of the forceps, and is generally long and straight. Such grasping instruments do not meet the requirements of laparoscopic breast surgery, especially laparoscopic breast-conserving surgery, where breast tissue is usually thicker, requires greater force to grasp, and requires a certain curvature to simulate the curvature of fingers in open surgery. In the narrow space of laparoscopic breast surgery, long straight instruments are more likely to cause the chopstick effect of laparoscopic surgery (which is not conducive to surgical exposure and operation). In addition, the fact that the grasping forceps and suction device are independent instruments also brings difficulties to the surgical space and the operator's operation. Therefore, the present invention proposes a special tissue grasping forceps with an adjustable suction device for laparoscopic breast surgery. Summary of the Invention

[0003] Based on the above problems, the purpose of the present invention is to provide a special tissue grasping forceps with an adjustable suction device for breast laparoscopic surgery. The present invention adopts the following technical solutions:

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, this embodiment discloses a special tissue grasping forceps with an adjustable suction device for laparoscopic breast surgery. The forceps comprises a double-section forceps body 1, with a fixed forceps arm 2 and a movable forceps arm 3 disposed at the front of the double-section forceps body 1. A forceps mouth 4 is disposed at the front ends of the fixed forceps arm 2 and the movable forceps arm 3. The double-section forceps body 1 primarily comprises a forceps body, with the fixed forceps arm 2 fixed to the forceps body and the movable forceps arm 3 rotatably connected to the forceps body. A connecting rod assembly is disposed within the forceps body, with the front end of the connecting rod assembly connected to the movable forceps arm 3 and the rear end of the connecting rod assembly connected to a movable handle, which is rotatably connected to the forceps body. A fixed handle is attached to one side of the movable handle, which is fixed to the forceps body. The movable handle and the fixed handle are provided with a toothed locking structure, which locks the movable and fixed handles together by engaging the toothed locking structure. When the movable handle is opened, the connecting rod assembly in the forceps body drives the movable forceps arm 3 to open as well. The structure of the double-section forceps body 1 is prior art and will not be described in detail in conjunction with the accompanying drawings in this embodiment.

[0026] like Figure 2 As shown, the fixed forceps arm 2 and the movable forceps arm 3 are bent at the same arc toward the plane area where the double-section forceps body 1 is located, so that the forceps mouth 4 can avoid the double-section forceps body 1 in the axial direction, having a good surgical field of view. At the same time, an aspirator 5 is arranged side by side on one side of the double-section forceps body 1. The aspirator 5 can absorb the smoke generated by the electric knife operation. At the same time, the aspirator 5 is integrated on the double-section forceps body 1, thereby reducing the difficulty of surgical operation in a limited surgical space.

[0027] like Figure 3 and 4 As shown, the jaws 4 include a pliers head 401, which is connected to the front end of the fixed pliers arm 2 or the movable pliers arm 3; the clamping surfaces of the pliers head 401 are provided with primary teeth 402, which are arranged in a one-to-one correspondence with the primary teeth 402 on the fixed pliers arm 2 and the primary teeth 402 on the movable pliers arm 3. At the same time, the clamping surface of the pliers head 401 is also provided with secondary teeth 403, which are located behind the primary teeth 402; the secondary teeth 403 on the fixed pliers arm 2 and the secondary teeth 403 on the movable pliers arm 3 are arranged in a one-to-one correspondence. This allows a certain amount of space between the fixed pliers arm 2 and the movable pliers arm 3, so that when clamping breast tissue, it can be clamped firmly while reducing the force on the tissue and reducing tissue damage.

[0028] like Figure 1 and 5As shown, the aspirator 5 is detachably connected to the double-section forceps body 1 via a connecting member 6. Specifically, the connecting member 6 includes a connecting block 601 fixed to the double-section forceps body 1. The connecting block 601 is provided with a mounting through-hole 602 arranged side by side with the double-section forceps body 1. The aspirator 5 passes through the mounting through-hole 602. The connecting block 601 is also provided with a locking member 603 for securing the aspirator 5. The front end of the aspirator can absorb smoke, droplets, and heat generated during the operation of energy devices such as electrocautery and ultrasonic scalpels. The rear end of the aspirator can be connected to a medium-negative pressure suction device through an external suction hose.

[0029] In this embodiment, the locking member 603 may be a bolt, which is connected to the connecting block 601 via threads, and the locking member 603 is in contact with the suction device 5 .

[0030] In this embodiment, the connecting member 6 further includes a guide sleeve 604 , which is fixed side by side on the double-section forceps body 1 , and the guide sleeve 604 is plugged into and matched with the suction device 5 .

[0031] In this embodiment, the suction device 5 is arranged on one side of the fixed forceps arm 2. This design allows the connected suction device hose to pass from the bottom, and at the same time facilitates the adjustment of the suction device 5, which has less impact on the surgical operation.

[0032] In this embodiment, the front end of the suction device 5 is pointed; an auxiliary hole 501 is provided on the outer wall of the front portion of the suction device 5 .

[0033] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
