Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vascular closure system capable of removing smoke in the laparoscopic surgical field. Background Art

[0002] Laparoscopes are the most commonly used medical devices in surgical operations and have currently been applied to more than 80% of surgical operations. Clinically, a laparoscope makes 3 - 4 small incisions in a patient's abdomen, and then trocars are respectively punctured and inserted through the incisions. Then, a long - rod lens is inserted into the abdominal cavity through one of the trocars, and the imaging system of the abdominal cavity lens is projected onto a display screen. Under the guidance of the imaging system, long - rod surgical instruments are inserted into the abdominal cavity through other trocars to perform operations on the diseased positions in the abdominal cavity.

[0003] During the operation, tissues need to be continuously dissected and hemostasis needs to be achieved. The vascular closure system plays a key role in this process. The vascular closure system is a new type of tissue coagulation device that can safely and quickly close blood vessels and tissue bundles with a diameter of less than 7 mm without generating eschar and has now been widely used in laparoscopic surgeries. It relies on the intelligent host to output high - frequency electric energy, combined with the pressure between the forceps, to melt and denature the collagen and fibrin of the blood vessels to be cut, and the blood vessel walls fuse to form a transparent zone, generating permanent lumen closure to provide hemostasis.

[0004] For patients with a large amount of visceral fat, due to the rich fat content, thick smoke that affects the lens field of view will be generated during the operation of the vascular closure system. To ensure a clear surgical field of view, a suction device is usually required to effectively suck this smoke. During operation, the suction device needs to occupy a separate trocar channel to cooperate with the vascular closure system. Since the number of trocar channels is limited, when frequent smoke suction is required, instruments may need to be continuously replaced. This will affect the effect of smoke suction and even cause smoke to adhere to the lens, requiring the lens to be frequently taken out and wiped. These steps not only increase the operation time, but also, the frequent entry and exit of the lens and instruments in the trocar may increase the secondary injury of the patient. In addition, the extension of the operation time will increase the risk of surgical complications and the anesthesia risk, thereby increasing the pain of the patient after surgery. Summary of the Utility Model

[0005] Aiming at the problems of poor smoking effect and long operation time caused by using a traditional vascular closure system in laparoscopic surgery, where a suction device needs to occupy a separate trocar channel for smoke suction, the purpose of the utility model is to provide a vascular closure system capable of removing smoke in the laparoscopic surgical field.

[0035] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0036] Please refer to Figures 1 to 5As shown in the figure, a vascular occlusion system capable of removing the smoke in the laparoscopic surgical field is shown. It includes: a main body 1, a tube assembly 2, and a suction device connecting tube 3. The front end of the main body 1 is equipped with the tube assembly 2, and the rear end of the main body 1 is connected with the suction device connecting tube 3. The suction device connecting tube 3 is used to connect the negative pressure suction device 4; one end of the suction device connecting tube 3 far from the main body 1 is connected with the negative pressure suction device 4, and the negative pressure suction device 4 provides negative pressure for the inside of the main body 1; the tube assembly 2 includes a forceps shaft 201, a forceps head 202, and a suction tube 203. One end of the forceps shaft 201 extends into the main body 1, and the other end of the forceps shaft 201 is equipped with the forceps head 202; the suction tube 203 is sleeved outside the forceps shaft 201; the suction tube 203 is connected with the front end of the main body 1; an aspiration channel 204 is formed between the inner wall of the suction tube 203 and the outer wall of the forceps shaft 201; a smoke suction port 205 is arranged at the front end of the suction tube 203; a connection channel 101 is arranged inside the main body 1; the aspiration channel 204 is communicated with the suction device connecting tube 3 through the connection channel 101; the smoke suction port 205 is arranged at the front end of the aspiration channel 204 and is close to the forceps head 202.

[0037] Furthermore, the connection channel 101 includes a connection pipeline 1011 and a connection cavity 1012. One end of the connection pipeline 1011 is communicated with the suction device connecting tube 3, and the other end of the connection pipeline 1011 is communicated with the connection cavity 1012; the connection cavity 1012 is arranged at the front part inside the main body 1; the connection cavity 1012 is communicated with the aspiration channel 204; a connection part is arranged at the front end of the main body 1, and the connection part is placed on the outer periphery of the forceps shaft 201; the front end of the connection part is hermetically connected with the suction tube 203.

[0038] Furthermore, a connection channel valve 5 is installed on the main body 1. The connection channel valve 5 is used to adjust the flow rate inside the connection pipeline 1011; preferably, the connection channel valve 5 is a sliding type flow regulator. The sliding type flow regulator realizes flow control by changing the pressure on the connection pipeline 1011; the flow regulator includes a runner and a trapezoidal track. The runner is installed on the trapezoidal track, and the connection pipeline 1011 passes through the trapezoidal track. When the runner slides forward, the connection pipeline 1011 can be flattened to reduce the amount of smoke passing through the connection pipeline 1011 per unit time; on the contrary, if the runner slides backward, the pressure on the connection pipeline 1011 is relaxed to increase the flow rate. The connection channel valve 5 adjusts the magnitude of the suction force by controlling the flow rate inside the connection pipeline 1011. In this way, the magnitude of the suction force can be adjusted according to the actual situation of smoke generation, making the operation more accurate and efficient. In addition, since the magnitude of the suction force can be directly adjusted on the main body 1, it is more convenient than operating on the negative pressure device 4.

[0039] Further, it further includes a first handle 6 and a second handle 7. The first handle 6 is connected to the lower end of the main body 1. The second handle 7 is installed at the lower end of the main body 1. The second handle 7 is used to control the closing of the jaws 202. The first handle 6 is for the palm to hold. The second handle 7 is movably connected to the lower end of the main body 1. When the second handle 7 is pressed, the closing of the jaws 202 can be controlled.

[0040] In a preferred embodiment, the clamping shaft 201 includes a push rod 2011, an outer sleeve 2012, a sliding block 2013 and a connecting pin 2014. The outer sleeve 2012 is sleeved outside the push rod 2011. The front end of the push rod 2011 is connected with the sliding block 2013. The front end of the outer sleeve 2012 is provided with a mounting groove, and the connecting pin 2014 is arranged in the mounting groove. The jaws 202 include two jaw connecting parts 2021 and two jaws 2022. One jaw connecting part 2021 is connected to one jaw 2022. Both of the two jaw connecting parts 2021 are placed in the mounting groove, and the two jaw connecting parts 2021 are rotatably connected to the outer sleeve 2012 through the connecting pin 2014. Both of the two jaw connecting parts 2021 are provided with sliding grooves 2023, and the sliding block 2013 penetrates through the two sliding grooves 2023. When in use, when the second handle 7 is pressed, the push rod 2011 can be driven to move backward, and then the sliding block 2013 slides backward in the two sliding grooves 2023. Since the backward movement of the sliding block 2013 drives the two jaw connecting parts 2021 to rotate inward, the two jaws 2022 are closed. When the second handle 7 is released, the push rod 2011 can be driven to move forward, and then the sliding block 2013 slides forward in the two sliding grooves 2023. Since the forward movement of the sliding block 2013 drives the two jaw connecting parts 2021 to rotate outward, the two jaws 2022 are opened.

[0041] In a preferred embodiment, the upper end of the second handle 7 extends into the main body 1, and the second handle 7 is rotatably connected to the main body 1. The main body 1 includes a housing, a swing rod and a return spring. The swing rod is rotatably connected inside the housing. One end of the swing rod is rotatably connected to the second handle 7, and the other end of the swing rod is rotatably connected to the rear end of the push rod 2011. When the second handle 7 is pressed, the second handle 7 drives the swing rod to rotate, and the swing rod drives the push rod 2011 to move backward, thereby closing the jaws 202. One end of the return spring abuts against the inside of the housing, and the other end of the return spring is connected to the second handle 7. The return spring is used to reset the second handle 7.

[0042] Further, the second handle 7 is provided with a finger through hole 701. When in use, the palm holds the first handle 6, and the index finger, middle finger and ring finger can pass through the finger through hole 701, which is more convenient for accurately controlling the second handle 7.

[0043] Further, a finger limiting part 702 is provided at the lower end of the second handle 7; during use, the palm holds the first handle 6, and the index finger, middle finger, and ring finger can pass through the finger passing opening 701; the little finger abuts against the front end of the finger limiting part 702. Such a design conforms to ergonomics and facilitates the comfort during use.

[0044] Further, it further includes a controller 8, and the controller 8 is electrically connected to the clamping head 202 through a connecting wire; the connecting wire passes through the interior of the main body 1 and the interior of the clamping shaft 201, and is electrically connected to the clamping head 202; the controller 8 provides electrical energy for the clamping head 202 to control the electrocoagulation operation of the clamping head 202; the controller 8 can transmit high-frequency electrical energy to the clamping head 202, and the clamping head 202 transfers the high-frequency current to the tissue, causing the tissue to undergo thermal coagulation, thereby achieving the purpose of hemostasis.

[0045] Further, the suction tube 203 is detachably connected to the main body 1; preferably, the suction tube 203 is threadedly connected to the main body 1; an external thread is provided at one end of the suction tube 203, and an internal thread is provided at the front end of the connecting part of the main body 1, and the internal thread matches the external thread. When installing the suction tube 203, the external thread end of the suction tube 203 can be sleeved from the end of the clamping head 202 until the external thread of the suction tube 203 is tightened with the internal thread of the connecting part of the main body 1. At this time, the front end of the suction tube 203 just exposes the clamping head 202. The function of the suction channel 204 is to suck the smoke, and the smoke will adhere to the inner wall of the suction tube 203 and the outer wall of the clamping shaft 201. The detachable connection method between the suction tube 203 and the main body 1 provides convenience for cleaning, disinfection, and maintenance after use.

[0046] Further, the tube body assembly 2 further includes a plurality of limiting blocks 206. One end of each limiting block 206 is connected to the inner wall of the suction tube 203, and the other end of each limiting block 206 abuts against the outer wall of the clamping shaft 201; the limiting blocks 206 are used to fix the suction tube 203 outside the clamping shaft 201. This structural design enhances the stability of the entire tube body assembly 2. During the operation, even if affected by a certain external force, it can ensure the stability of the relative position between the suction tube 203 and the clamping shaft 201, ensuring the consistency of the smoking effect and the safety of the operation process.

[0047] Further, a smoking port 205 is provided between any two adjacent limiting blocks 206; two adjacent limiting blocks 206, the inner wall of the suction tube 203, and the outer wall of the clamping shaft 201 together form a smoking port 205, and a plurality of smoking ports 205 surround the outer wall of the clamping shaft 201; the smoking port 205 is arranged at a position close to the clamping head 202, and the smoking port 205 surrounds the front end of the clamping shaft 201.

During the operation, press the second handle 7 to control the closing of the forceps head 202, and control the electrocoagulation operation of the forceps head 202 through the externally connected controller 8. When smoke is generated, turn on the externally connected negative pressure suction device 4. The thick smoke enters the suction channel 204 from the smoke suction port 205, then flows through the connection cavity 1012, then enters the suction device connecting tube 3 through the connecting pipe 1011, and finally enters the negative pressure device 4. In addition, during this smoking process, the magnitude of the suction force can be adjusted by controlling the connection channel valve 5.

[0050] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model.
