Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a novel laparoscopic surgical instrument. Background Art

[0002] Laparoscopic surgery, also known as minimally invasive surgery, is performed under the field of view of the laparoscope, in which the doctor operates laparoscopic surgical instruments through a screen. Since local bleeding may occur during laparoscopic surgery, the mechanical clamps at the end of the surgical instruments are needed to tighten the blood vessels and clamp the tissues to achieve the effect of hemostasis.

[0003] However, the surgical instruments in the prior art have single functions. For example, hemostatic forceps can only achieve a simple tightening and hemostasis function, but cannot flush the bleeding site. Therefore, the doctor needs to replace another surgical instrument to flush the bleeding site after the hemostasis is completed, which not only greatly increases the risk of infection for the patient, but also increases the doctor's workload. Utility Model Content

[0020] Embodiment 1

[0021] The surgical instruments in the prior art have a single function, and doctors need to frequently change surgical instruments during surgery, which not only increases the workload of doctors, but also makes the instruments often exposed to the air and easily cause infection. In order to solve this technical defect in the prior art, Figure 1-Figure 3 As shown, this embodiment proposes a novel laparoscopic surgical instrument, which can integrate the flushing function into the structure of the forceps, so that one surgical instrument has two different functions at the same time. A movable handle 1 is movably installed on the fixed handle 2 of the surgical instrument, and a reset spring is arranged between the movable handle 1 and the fixed handle 2. The fixed handle 2 is provided with a clamping hemostatic mechanism 3 for quickly clamping blood vessels or tissues during surgery, and a local flushing mechanism 4 for flushing the bleeding site is arranged inside the clamping hemostatic mechanism 3. If local bleeding occurs during the operation, the doctor will first use the clamping hemostatic mechanism 3 to quickly stop the bleeding at the bleeding site, and then use the local flushing mechanism 4 to flush the bleeding site.

[0022] In order to stop bleeding and flush the bleeding site in time during the operation, the present embodiment is provided with a clamping hemostasis mechanism 3 and a local flushing mechanism 4. Specifically, the clamping hemostasis mechanism 3 includes a rotating wheel 301 detachably mounted on the fixed handle 2, a stainless steel outer tube 303 is coaxially mounted on the rotating wheel 301, a sliding inner tube 302 is coaxially arranged inside the stainless steel outer tube 303, one end of the sliding inner tube 302 extends out of the stainless steel outer tube 303 and is fixedly connected to a short pull tube 304, a clamping assembly 305 for clamping a blood vessel for hemostasis is provided on the short pull tube 304, and the clamping assembly 305 consists of a fixed clamp head and a movable clamp head. The fixed pliers head and the movable head are fixed by pins, the short pull tube 304 is riveted to the movable head, and when the short pull tube 304 moves with the sliding inner tube 302, the angle between the movable head and the fixed pliers head will change. The fixed handle 2 is provided with a connecting assembly 306 for fixing the stainless steel outer tube 303, and the connecting assembly 306 is composed of an outer tube adapter, a ratchet and an installation tail cover 403, and the outer tube adapter, the ratchet and the installation tail cover 403 are all fixedly sleeved on the fixed handle 2, and the outer tube adapter matches the stainless steel outer tube 303. When installed, the stainless steel outer tube 303 will be fixedly connected to the outer tube adapter. The rotating wheel 301, the stainless steel outer tube 303, and the outer tube adapter are all provided with circular grooves matching the flushing connector 405. After the doctor puts the rotating wheel 301 on the outer tube adapter, the flushing connector 405 is inserted into the circular groove, thereby fixing the positions of the rotating wheel 301 and the stainless steel outer tube 303. A ball pull head 307 is fixedly installed on the movable handle 1, and the other end of the sliding inner tube 302 is fixedly connected to the ball pull head 307. When the doctor presses the movable handle 1, the sliding inner tube 302 will slide along the stainless steel outer tube 303. The local flushing mechanism 4 includes a detachable A water valve switch 404 is installed on the fixed handle 2, and a transfer interface 401 and a metal tube 402 are fixedly connected to the water valve switch 404. A flushing joint 405 is provided on the rotating wheel 301. After the water valve switch 404 is turned on, the flushing liquid will enter the interior of the stainless steel outer tube 303 through the flushing joint 405, and spray outward from between the stainless steel outer tube 303 and the sliding inner tube 302. A silicone cap 406 is provided on the upper end of the flushing joint 405. Before the flushing operation, the silicone cap 406 will cover and protect the upper end of the flushing joint 405 to prevent the interior of the stainless steel outer tube 303 from being contaminated.

[0023] In this embodiment, when installing the surgical instrument, the medical staff will first fix the movable head and the fixed forceps head together through pins, insert the short pull tube 304, and then rivet the short pull tube 304 and the movable head together.

[0024] Next, the sliding inner tube 302 is welded with the short pull tube 304, and then the sliding inner tube 302 is inserted into the interior of the stainless steel outer tube 303, and the sliding inner tube 302 is fixedly connected to the ball pull head 307. Subsequently, the installation tail cover 403, ratchet and outer tube joint are sequentially inserted into the fixed handle 2 and fixed with a nut.

[0025] Next, insert the adapter 401 and the metal tube 402 into the holes on both sides of the water valve switch 404 respectively, and then embed them into the interior of the fixed handle 2. Next, use the shaft screw to install the movable handle 1 on the fixed handle 2. Finally, put the wheel 301 into the outer tube adapter, fix it with the flush connector 405, and put on the silicone cap 406.

[0026] During the laparoscopic surgery on the patient, if local bleeding occurs, the doctor will first insert the stainless steel outer tube 303 of the surgical instrument into the patient's abdominal cavity and move the clamping assembly 305 to the designated position of the bleeding site. Next, the doctor will manually press the movable handle 1 to move the ball pull head 307 outward. When the ball pull head 307 moves, the sliding inner tube 302 and the short pull tube 304 will move synchronously, so that the movable head and the fixed clamp head are close to each other. In the process of approaching each other, the local tissue or blood vessel will be clamped to achieve the effect of hemostasis.

[0027] After hemostasis is completed, there is no need to pull out the stainless steel outer tube 303. It is only necessary to connect the flushing liquid pipeline to the flushing connector 405. Then the doctor will control the flow rate and flow of the flushing liquid through the water valve switch 404 to complete the rapid flushing of the bleeding site.

[0028] This embodiment provides a clamping hemostasis mechanism 3 and a local flushing mechanism 4, and utilizes the mutual cooperation between the sliding inner tube 302 and the stainless steel outer tube 303 to integrate the flushing function into the structure of the forceps, so that one surgical instrument has two different functions at the same time, which can effectively reduce the frequency of doctors replacing surgical instruments during surgery, thereby reducing the time the instruments are exposed to the air and reducing the risk of infection; in addition, this embodiment provides a clamping hemostasis mechanism 3, and utilizes the mutual cooperation between the stainless steel outer tube 303 and the flushing connector 405 to enable the flushing liquid to flow from the gap between the sliding inner tube 302 and the stainless steel outer tube 303, thereby synchronously flushing the surfaces of the sliding inner tube 302 and the clamping assembly 305, which is easy to use.
