[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Laparoscopic surgery originated in the 1980s, and with advancements in optics, electronics, and mechanics, laparoscopic techniques have gradually matured. Compared to traditional open surgery, laparoscopic surgery involves inserting a laparoscope and surgical instruments through small incisions, reducing surgical trauma and shortening patient recovery time. Laparoscopic surgical forceps, as the primary operating tool in the procedure, need to be designed to meet the specific requirements of minimally invasive surgery.
[0023] Due to the technical drawbacks of existing technologies, where other organs inside the wound can easily obstruct the use of surgical forceps, please refer to... Figures 1-4 This utility model provides a laparoscopic minimally invasive surgical forceps that spreads other organs in the surgical area to the sides to expose the surgical area, thus facilitating various surgical operations and avoiding difficulties caused by obstruction. The surgical forceps include a long rod 2, with a holding component 1 fixed at one end and a clamping component 3 connected to the holding component 1 at the other end. A spreading component 4 is sleeved on the outer wall of the long rod 2. In use, the doctor holds the holding component 1 with two fingers of one hand, and then compresses the spring 403 in the spreading component 4 with the other hand, causing the spreading rod 406 to close. At this time, the entire forceps can be inserted into the patient's body through the incision. Then, when the front part of the long rod 2 moves to the surgical area inside the patient, the spreading component 4 is used to spread other organs in the surgical area to the sides. Finally, the surgical operation can be performed by clamping component 3.
[0024] Existing laparoscopic surgical forceps rely on the foremost jaw 306 for surgical manipulation. However, due to the small size of the incision and the presence of other organs inside, this jaw can easily obstruct the surgical site, affecting the proper use of the forceps. For solutions to this problem, please refer to... Figure 2The spreading assembly 4 includes a sleeve 401 fitted onto a long rod 2. A fixing ring 402, fixed to the long rod 2, is provided on one side of the sleeve 401. A second spring 403 is fitted onto the outer wall of the sleeve 401. An operating ring 404, fitted onto the sleeve 401, is connected to one side of the second spring 403. One end of the operating ring 404 is hinged to a spreading rod 406 via a hinge rod 405. One end of the spreading rod 406 is hinged to the outer wall of the sleeve 401. Before the surgical forceps are inserted into the wound... The operating ring 404 needs to be moved and the second spring 403 needs to be compressed. At this time, the spreading rod 406 closes inward. When the surgical forceps enter the patient's body and move to the surgical area, the operating ring 404 can be released. At this time, under the elastic force of the second spring 403, the operating ring 404 can be pushed to move, and under the action of the hinge rod 405, the spreading rod 406 will open to both sides, thereby spreading other organs to both sides, reducing obstruction and exposing the surgical area.
[0025] Furthermore, to ensure that the operating ring 404 can be operated externally, the two ends of the operating ring 404 are ring-shaped and the middle is hollow. In this way, one end of the operating ring 404 can be outside the body and the other end can be inside the body, making it convenient to close and open the spreading rod 406.
[0026] When using surgical forceps, the surgeon needs to control the movement of the forceps jaws 306 with their hands. For this purpose, please refer to... Figure 3 The gripping assembly 1 includes a fixed handle 101 fixed to one end of the long rod 2. A movable handle 102 is rotatably connected to the fixed handle 101 via a pivot. A metal spring 104 connected to the movable handle 102 is fixed to the inner side of the fixed handle 101. A locking unit 103 is fixed to the side wall of the fixed handle 101 to keep the movable handle 102 in a fixed position. The fixed handle 101 is directly fixed to the long rod 2 and remains stationary. The doctor inserts two fingers of one hand into the holes of the fixed handle 101 and the movable handle 102 respectively. The finger inserted into the movable handle 102 is usually the thumb. The movement of the thumb can drive the movable handle 102 to move. The movable handle 102 drives the gripping assembly 3 to move in order to control the movement of the jaws 306. The metal spring 104 can be used to spring back and reset the movable handle 102.
[0027] Furthermore, during surgery, it is sometimes necessary to keep the clamping jaws 306 in a clamping state for an extended period. This requires the surgeon's hand to continuously apply force to the gripping component 1. Prolonged application of this force can lead to hand fatigue. For more information on this issue, please refer to [link / reference needed]. Figure 3The locking unit 103 includes a fixing strip 1031 fixed to the side wall of the fixing handle 101. The fixing strip 1031 is provided with an adjustment hole, and a bolt 1032 threadedly connected to the side wall of the movable handle 102 is provided in the adjustment hole. When it is necessary to keep the jaws 306 in a clamping state, the movable handle 102 is fixed by the bolt 1032, so that the movable handle 102 remains stationary. This can avoid the problem of hand fatigue caused by the doctor keeping the jaws 306 in a clamping state for a long time during the operation.
[0028] For ease of performing various surgical procedures, please refer to Figure 4 The clamping assembly 3 includes a connecting rope 301 disposed inside the long rod 2. One end of the connecting rope 301 is connected to the movable handle 102, and the other end is connected to the hinge block 302. A spring 303 is connected to one side of the hinge block 302. The spring 303 is fixed inside the long rod 2 by a fixing block 304. Two hinge pieces 305 are hinged to the inner side of the hinge block 302. The two hinge pieces 305 are respectively hinged to one end of two jaws 306. The two jaws 306 are rotatably connected to the end of the long rod 2 away from the holding assembly 1 by a pin. The inner surfaces of the two jaws 306 are serrated. When the movable handle 102 moves and pulls the hinge block 302 through the connecting rope 301, the hinge block 302 can drive the jaws 306 to open or close through the hinge pieces 305, thereby clamping. Under the action of the spring 303, the jaws 306 can be reset.
[0029] Furthermore, since the hinge plate 305 needs sufficient movement space when driving the jaws 306 to move, a "U"-shaped slot 201 is provided at the end of the long rod 2 away from the gripping component 1; the slot 201 provides movement space for the hinge plate 305 to ensure the normal use of the jaws 306.
