Description

Technical Field

[0001] The invention relates to the technical field of laparoscopic surgery, in particular to an automatic wiper for a laparoscopic lens. Background Art

[0002] Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the development of surgical methods in the future. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open surgeries in the past have now been replaced by endoscopic surgeries, greatly increasing the opportunities for surgical options.

[0003] However, when the laparoscope is in use, since the lens needs to be inserted into the patient's body, the lens surface will be stained with blood, causing the lens to be blurred, and the surgical field of view during the operation is unclear. At this time, the laparoscope needs to be taken out and wiped, and then inserted into the patient's body again after wiping is completed. However, the surgical operation must be paused during the wiping, and the operation can only be started again after the laparoscope is wiped clean and put back into the body. Due to the temperature difference between the outside and inside of the body, although the laparoscope is wiped clean outside the body, the surface of the lens will be fogged due to the temperature difference when it is put back into the body. It is often necessary to take it out and wipe it repeatedly outside the body, which undoubtedly delays the operation time. During the operation, the patient's body tissue will also hinder the lens. At the same time, the blood and body fluids in the patient's body can easily seep out from the surgical incision and cause contamination. Summary of the invention

[0011] Preferably, the left end surface of the mounting plate is connected to a first magnet, the left end surface of the first magnet is connected to a first iron sheet connected to the inner wall of the connecting plate, a second plug rod is inserted through the top of the mounting plate, the right end surface of the second plug rod is connected to a lever protruding from the outside of the mounting plate, the top end of the second plug rod is connected to a second magnet, and the top end of the second magnet is connected to a second iron sheet connected to the inner wall of the connecting plate.

[0012] Preferably, a battery compartment is provided on the right end surface of the fixing ring, fixing bolts are inserted through the upper and lower ends of the fixing ring, and the inner ends of the fixing bolts penetrate the interior of the laparoscope rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The automatic wiper of the laparoscope lens is provided with a baffle plate, on which a medical sponge is connected. When performing an operation, the baffle plate is pushed on the laparoscope rod by an electric telescopic rod, so that the medical sponge seals the incision on the patient's body used for the operation, thereby avoiding contamination caused by leakage of blood and body fluids in the patient's body.

[0015] 2. The automatic wiper of the laparoscope lens is provided with a spring, and the two ends of the spring are respectively connected to the connecting ring and the blocking plate. In this way, when the blocking plate moves, the elastic force of the spring hinders the blocking plate, so that the blocking plate can move slowly, so that the blocking plate will not move a large distance at one time, avoiding damage to the incision.

[0016] 3. The automatic wiper of the laparoscope lens is provided with a catheter and a water bag. The catheter is filled with water through the water inlet. The water enters the water bag through the catheter. The water bag expands at this time and can stretch the tissue inside the patient's body, thereby avoiding obstruction of the lens to widen its field of view and ensure that the patient's body can be explored without obstruction during surgery.

[0017] 4. The automatic wiper of the laparoscope lens is provided with a brush which is mounted on a connecting plate which is connected to a tooth block. When the tooth block is controlled to rotate by a micro motor, it will make a circular motion on the connecting ring. At this time, the connecting plate will also make a circular motion synchronously through the rotation of the tooth block. Thus, the brush rotates to clean the surface of the lens to remove pollutants or water mist attached to the surface of the lens, thereby ensuring that the field of view will not be blocked during surgery.

[0018] 5. The automatic wiper of the laparoscopic lens, by setting the above series of structures, allows the lens to be cleaned without removing the patient during laparoscopic surgery, and can prevent the patient's body tissue from blocking the lens's field of view, while also preventing the patient's blood and body fluids from seeping out from the incision.

[0030] like Figure 1-5As shown, the automatic wiper for the laparoscope lens of this embodiment comprises a laparoscope rod 1, a lens 2 connected to the left end surface of the laparoscope rod 1 and a connecting ring 3 sleeved on the outer surface of the lens 2. The outer surface of the laparoscope rod 1 is sleeved with a blocking plate 6, and the blocking plate 6 can slide freely on the laparoscope rod 1. A medical sponge 7 is bonded and connected to the surface of one end of the blocking plate 6 close to the laparoscope rod 1. The blocking plate 6 contacts the skin at the abdominal incision of the patient, thereby blocking it, and preventing the body fluid and blood from seeping out of the human body through the medical sponge 7. The upper and lower ends of the interior of the blocking plate 6 are penetrated by a catheter 8, and the catheter 8 is a telescopic hose structure. A water injection port 9 is provided at the right end of the catheter 8, and water can be injected into the catheter 8 by connecting an external pipeline through the water injection port 9. A water bag 10 is connected to the left end of the catheter 8. Water enters the water bag 10 through the catheter 8, thereby expanding the water bag 10 to expand the internal tissue of the human body so that the lens 2 can better perform video inspection. The water bag 10 is wrapped on the outer surface of the connecting ring 3. A first recess 11 is provided on the left end surface of the connecting ring 3. The inner wall of the first recess 11 is evenly distributed with serrated protrusions. A tooth block 14 is provided inside the first recess 11. The tooth block 14 is completely recessed inside the first recess 11. The tooth block 14 is completely recessed inside the first recess 11. The block 14 is meshed and connected with the inner wall of the first recess 11, so that the tooth block 14 can perform a circular motion on the connecting ring 3 when rotating. The left end surface of the tooth block 14 is connected with a micro motor 15, and the model of the micro motor 15 is Y90S-2, which controls the tooth block 14 to rotate. The outer surface of the micro motor 15 is connected with a connecting block 16, and the connecting block 16 allows the micro motor 15 to be stably installed.

The right end surface of the blocking plate 6 is connected to an electric telescopic rod 27, and the electric telescopic rod 27 can control the blocking plate 6 to move on the laparoscope rod 1 by telescoping. The right end of the electric telescopic rod 27 is connected to a fixing ring 28 sleeved on the outer surface of the laparoscope rod 1. The fixing ring 28 is firmly connected to the laparoscope rod 1, so that the structures such as the connecting ring 3 and the blocking plate 6 can be stably installed on the laparoscope rod 1.

[0031] Specifically, an inner cavity 4 is opened in the middle of the connecting ring 3 , and the diameter of the inner cavity 4 is the same as the diameter of the lens 2 , so that the lens 2 can pass through the connecting ring 3 to perform video inspection on the inside of the human body.

[0032] Furthermore, a spring 5 is symmetrically connected to the front and rear surface of the right end of the connecting ring 3, and the right end of the spring 5 is connected to the blocking plate 6. Due to the elasticity of the spring 5 itself, the electric telescopic rod 27 can move the blocking plate 6 slowly when pushing it to move, and there will be no damage to the patient's surgical incision caused by moving a large distance at one time.

[0033] Furthermore, the longitudinal section of the first recess 11 is annular in structure, and a second recess 12 opened on the connecting ring 3 is provided inside the first recess 11, and a limit block 13 is engaged inside the second recess 12, and the left end of the limit block 13 is connected to the tooth block 14. The limit block 13 is engaged with the second recess 12, so that the tooth block 14 will not fall off from the inside of the first recess 11.

[0034] Furthermore, a groove structure is provided on the top of the connecting plate 18, and a battery box 17 is inserted into the interior of the groove structure.
