Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a laparoscope auxiliary device with an exhaust function. Background Art

[0002] In laparoscopic surgery, in order to create sufficient surgical space and provide a good surgical field of view, carbon dioxide gas is usually injected into the abdominal cavity to form pneumoperitoneum. First, the doctor will select a suitable position in the patient's abdomen and use local anesthesia or general anesthesia to make the patient painless. Then, the puncture needle is used to explore the situation in the abdominal cavity, establish the initial pneumoperitoneum channel and inject carbon dioxide gas to form the "pneumoperitoneum" required for the operation. Next, the trocar is placed into the abdominal wall along the path of the puncture needle. Once it enters the abdominal cavity, the puncture needle is pulled out. At this time, the trocar becomes an important channel for communication between the inside and outside of the abdominal cavity. Through the trocar, the doctor can insert the laparoscope into the abdominal cavity for observation and operation, and can also replace other surgical instruments such as grasping forceps, separation forceps, cutting electrocoagulation instruments, etc. for minimally invasive surgery.

[0003] During the operation, since the cutting electrocoagulation instrument will produce smoke when used, which affects the surgical field of view, an aspirator device is usually used or the gas is filtered into a liquid. If the aspirator device emits smoke, if the suction force is too large, it will easily affect the pneumoperitoneum pressure, thereby affecting the surgical field of view. If the gas is filtered into a liquid, the liquid will easily wet the operating table, causing contamination of the sterile table. Utility Model Content

[0033] The embodiment of the present application provides a laparoscopic assist device with an exhaust function, and the laparoscopic assist device with an exhaust function is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0034] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] Example 1

[0036] See also Figure 1-6 In the present embodiment, a laparoscopic auxiliary device with exhaust function is provided, comprising: a liquid storage bag 1, a fixed block 2 is connected to the top of the liquid storage bag 1, a hose 3 is connected to the top of the fixed block 2, and a clamp 4 is provided on the top of the fixed block 2; an exhaust component arranged inside the fixed block 2, used for exhausting the gas inside the liquid storage bag 1; and an extrusion component arranged between the fixed block 2 and the hose 3, used for squeezing the hose 3 to adjust the gas flow rate.

[0037] The liquid storage bag 1 is in a triangular structure and is packaged in a polyvinyl chloride (PVC) soft bag. Polyvinyl chloride is a commonly used medical soft packaging material. It has good flexibility, transparency, chemical stability and relatively low cost. The liquid storage bag 1 can be clamped on the tablecloth on the operating table by the setting of the clip 6. The fixing block 2 is in a flat rectangular structure, which can also facilitate medical staff to use a fixing fixture to clamp and fix.

[0038] Among them, through the setting of the liquid storage bag 1 and the exhaust component, the gas inside the liquid storage bag 1 can be discharged, and at the same time, water leakage is not likely to occur, the table is kept sterile, and the air in the operating room is not easily polluted. At the same time, the liquid storage bag 1 comes with a hose 3, which can save the use of a suction tube. Secondly, through the setting of the extrusion component, the gas flow rate inside the hose 3 can be changed, thereby assisting in controlling the change of air pressure inside the abdominal cavity, and preventing the air pressure from changing too quickly and affecting the progress of abdominal surgery.

[0039] Example 2

[0040] On the basis of Example 1, the exhaust assembly includes: an exhaust cavity 201 opened inside the fixed block 2; a baffle 202 installed inside the exhaust cavity 201, and a vent 203 is opened on the baffle 202; an exhaust hole 207 opened on one side of the fixed block 2; an opening 204 opened at the bottom of the fixed block 2, and the top end of the hose 3 is connected to the Trocar.

[0041] Among them, the opening 204 is communicated with the exhaust chamber 201, a solenoid valve is provided inside the opening 204, an air pressure sensor 2041 is installed at the bottom of the fixed block 2, the exhaust hole 207 is communicated with the exhaust chamber 201, a return spring 205 is connected to the exhaust chamber 201, a sealing plate 206 is connected to the bottom end of the return spring 205, and the sealing plate 206 cooperates with the vent 203, the sealing plate 206 is made of rubber material, and the liquid storage bag 1 is filled with physiological saline to keep the table sterile.

[0042] The smoke generated during laparoscopic surgery can be discharged into the physiological saline in the liquid storage bag 1 through the hose 3, thereby reducing the pneumoperitoneum pressure and reducing the occurrence of surgical complications. As the gas is continuously discharged, the pressure inside the liquid storage bag 1 rises. At this time, the electromagnetic valve inside the opening 204 is opened by the air pressure sensor 2041, allowing the gas inside the liquid storage bag 1 to be discharged into the exhaust chamber 201 through the opening 204. Since there is a certain air pressure difference between the upper and lower parts of the sealing plate 206, the sealing plate 206 moves upward under the action of the air pressure difference, opening the vent 203, allowing the gas inside the liquid storage bag 1 to pass through. The air is discharged to the exhaust hole 207 through the vent hole 203 and then discharged to the outside through the exhaust hole 207. After the air pressure inside the liquid storage bag 1 drops, the sealing plate 206 rebounds under the action of the elastic force of the return spring 205, so that the sealing plate 206 blocks the vent hole 203 again. Through the arrangement of the sealing plate 206 and the return spring 205, the function of mechanical automatic exhaust can be added on the basis of the exhaust sensing by the air pressure sensor 2041, so as to avoid the air pressure sensor 2041 having an abnormal problem and being unable to close the opening 204, and the sealing plate 206 can block the vent hole 203.

[0043] Example 3

[0044] On the basis of Example 1, the extrusion assembly includes: an adjusting chamber 4 opened inside the fixed block 2, and a conical adjusting plate 401 is provided inside the adjusting chamber 4; a sleeve 301 is provided inside the fixed block 2, and the bottom end of the hose 3 passes through the sleeve 301 and extends to the liquid storage bag 1, and part of the sleeve 301 is located inside the adjusting chamber 4; a threaded hole 403 is opened on one side of the fixed block 2, and a threaded rod 402 is passed through the threaded hole 403, and one end of the threaded rod 402 extends into the adjusting chamber 4 and is connected to the adjusting plate 401 through a bearing.

[0045] A receiving groove 503 communicating with the threaded hole 403 is provided inside the fixed block 2 , a moving groove 5 communicating with the receiving groove 503 is provided inside the fixed block 2 , and a moving block 501 with an L-shaped structure is provided inside the moving groove 5 .

[0046] Furthermore, one end of the movable block 501 protrudes from the outer surface of the fixed block 2, the bottom end of the movable block 501 extends to the inside of the storage groove 503 and is connected to the arc block 502, and the inner arc surface of the arc block 502 is provided with a plurality of slots, the arc block 502 is engaged and connected with the threaded rod 402 through the slots, a limiting hole is provided on the movable block 501, a limiting rod 504 is connected to the inside of the movable groove, and the limiting rod 504 passes through the limiting hole.

[0047] In laparoscopic surgery, in order to prevent the gas from being discharged too quickly, which may cause the pneumoperitoneum pressure in the abdominal cavity to drop too quickly and affect the doctor's surgical field of view, the sleeve 301 can be squeezed by the adjustment plate 401, so that the sleeve 301 squeezes the hose 3 inside it, thereby changing the gas flow cross-section inside the hose 3, and then controlling the gas flow speed;

[0048] When the gas flow rate needs to be adjusted, the moving block 501 is moved upward, so that the moving block 501 drives the arc block 502 to be stored in the storage groove 503, so that the arc block 502 is separated from the threaded rod 402, and then the threaded rod 402 is rotated, and the threaded connection of the threaded rod 402 in the threaded hole 403 drives the adjustment plate 401 to move toward the sleeve 301, so as to squeeze the sleeve 301. After the adjustment is completed, the moving block 501 is moved downward, so that the moving block 501 drives the arc block 502 to move out of the storage groove 503, and the inner arc surface of the arc block 502 contacts the surface of the threaded rod 402. At this time, the threads on the threaded rod 402 are just inserted into the grooves on the arc block 502, so that the threaded rod 402 is clamped and fixed. At the same time, the sleeve 301 will exert a reaction force on the adjustment plate 401 after being squeezed and deformed, so that the adjustment plate 401 and the threaded rod 402 tend to move outward, so that the threads on the threaded rod 402 are tightly attached to the threaded hole 403 and the grooves on the arc block 502, which further plays a fixing effect, ensuring that the position of the threaded rod 402 is fixed, and avoiding the position deviation of the threaded rod 402 to affect the squeezing effect of the sleeve 301 on the hose 3, thereby affecting the flow rate of the gas.
