Description

Technical Field

[0001] This invention relates to the field of protective device technology, specifically to a reusable protective device for a laparoscopic aspirator. Background Technology

[0002] The laparoscopic aspirator is a fundamental instrument in laparoscopic surgery. Its main functions are flushing and suction. Its most basic function is to flush the surgical field and suction. It can not only remove liquids, gases, or debris from the body cavity, but also remove blood and smoke, thus better maintaining a clean and clear surgical field. This is beneficial for precise and minimally invasive operations during surgery. In addition to the basic flushing and suction functions, the laparoscopic aspirator can also perform multiple operations such as "pressing," "blocking," "picking," and "separating." These functions make laparoscopic surgery clearer and more efficient. Since laparoscopic surgery is a minimally invasive surgical technique, it has advantages such as less trauma and faster recovery compared to traditional open surgery. The laparoscopic aspirator plays a key role in this process, helping doctors maintain a clear field of vision during surgery and ensuring the precision of the operation. The laparoscopic aspirator protection device is a device designed to effectively protect the aspirator during laparoscopic surgery. Its main purpose is to prevent the greater omentum or other tissues from interfering with or blocking the aspirator during the operation. Through specific design and structure, the aspirator can be used more smoothly, improving surgical efficiency and safety. The design of the protection device makes it easy to clean and disinfect, meets the hygiene requirements of medical devices, and reduces the risk of postoperative infection. The laparoscopic aspirator, disclosed in patent CN115887020A, includes a hollow cylinder with a suction and irrigation rod, an irrigation tube connector, and a suction tube connector connected to its outer side. It also includes a rotating cylinder with one end located inside the hollow cylinder; an operating push rod disposed on the rotating cylinder; and a first connecting component that pushes the operating push rod and connects the suction and irrigation rod to the irrigation tube connector. By simultaneously pressing and pulling the operating push rod, and using a linkage component to move and rotate the suction and irrigation rod, the suction port of the suction and irrigation rod will not remain in one place for an extended period, thus reducing the probability of aspirating human tissue. Therefore, medical personnel only need to stabilize their arms before pulling the operating push rod to slowly move the suction and irrigation rod, reducing the difficulty of operation and the probability of the aspirator aspirating human tissue. In the patent application CN219127605U, entitled "A Novel Laparoscopic Aspirator," a control block and a disposable cage sleeve are included. The control block has a mounting screw on its left side, and a suction tube is mounted on the left side of the mounting screw. The surface of the suction tube's end has double rows of suction holes, and a mounting ring is fitted around the suction tube. The disposable cage sleeve is positioned on the side of the mounting ring, and the inner wall of the mounting ring has a mounting component for fixing the disposable cage sleeve to prevent it from falling off. The mounting component includes a mounting plate, a mounting cavity, and a mounting hole. The mounting plate has a mounting cavity inside. This novel laparoscopic aspirator uses a disposable silicone cage sleeve fitted over the double rows of suction holes, making it less likely for the suction tube to suck up the membrane. It is also highly hygienic for single use, inexpensive, and has a low cost. The mounting component serves to fix and limit the disposable cage sleeve, and the auxiliary component assists the doctor in controlling the operation of the button valve. The patent application CN213374196U, entitled "A Multifunctional Laparoscopic Aspirator," includes: an aspiration head, a negative pressure absorption device, an irrigation tube, and an aspiration handle. The aspiration head is characterized by having either a hook aspiration head with serrated ends or a separation aspiration head with smooth ends, and both the hook aspiration head and the separation aspiration head have through holes on their surfaces. A valve cylinder is positioned between the aspiration head and the aspiration handle, and the valve cylinder is detachably connected to both the aspiration head and the aspiration handle. A tube opening is provided through the outer surface of the valve cylinder. A two-way valve body is positioned inside the valve cylinder at the corresponding tube opening, allowing the irrigation tube opening to be opened while simultaneously closing the negative pressure tube opening, or vice versa. The hook aspiration head is used to pull the intestines and greater omentum, while the separation aspiration head bluntly separates adhesions and gaps in visceral tissues. The surgeon can directly control the irrigation tube and the negative pressure device via the two-way valve body within the valve cylinder, avoiding the need to manually switch the irrigation tube or the negative pressure device during surgery. When performing abdominal aspiration with existing laparoscopic aspirators, the presence of omentum, pus, blood clots, etc., within the tissue can cause the aspirator head to suck in the omentum due to improper operation, resulting in injury to the patient. This can also affect the normal use of the laparoscopic aspirator in the later stages and reduce the efficiency of subsequent surgeries. Therefore, we propose a reusable protective device for laparoscopic suction devices to address the problems mentioned above. Summary of the Invention

[0003] The purpose of this invention is to provide a reusable protective device for a laparoscopic aspirator, in order to solve the problem mentioned in the background art that existing laparoscopic aspirators on the market, when performing abdominal aspiration, may cause the omentum to be sucked in due to improper operation because of the presence of omentum, pus, blood clots, etc. in the tissue, which can cause injury to the patient. At the same time, it will also affect the normal use of the laparoscopic aspirator in the later stages and reduce the efficiency of the subsequent surgery.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a reusable laparoscopic aspirator protection device, comprising a valve body, wherein a connecting tube is installed through a grooved and sealed end on the right end of the valve body, and a sealing plate is installed through a sealed end on the outer end of the connecting tube. It also includes: a valve body, with a discharge pipe installed through its left end in a sealed manner, the discharge pipe having the same diameter as the suction pipe, and a movable handle installed at the top of the valve body, while a positioning rod is installed at the bottom of the valve body; a sealing plate, with a suction pipe installed through its outer side in a sealed manner, and a suction head connected to the outer end of the suction pipe in a sealed manner, while the suction head is in an inclined shape. The sealing plate has a sleeve installed through its outer end, and a suction tube is correspondingly installed on the inner side of the sleeve. A filter head is installed at the outer end of the sleeve, and a suction head is correspondingly installed on the inner side of the filter head. The diameter of the sleeve is larger than the diameter of the suction tube. The suction tube has a positioning frame installed with a slotted screw inside. A single-turn reciprocating screw is installed through the slotted part of the positioning frame via a bearing. The positioning frame is hollow, and the single-turn reciprocating screw is rotatably installed inside the suction tube.

[0005] Preferably, the sleeve has two limiting rods that are slidably installed through the groove at its outer end. The two limiting rods are symmetrically arranged about the vertical center line of the sleeve, and both limiting rods extend through the first limiting groove to the outer ends of the sealing plate. At the same time, the two first limiting grooves are symmetrically opened at both ends of the sealing plate. The sealing plate has second limiting grooves at both its upper and lower ends, and the two second limiting grooves are the same size.

[0006] Preferably, the sleeve has slots at both ends for compression springs, the two compression springs have the same structure, and the outer ends of the two compression springs are connected to limit rods.

[0007] Preferably, the suction tube has damping rods screwed on at both its upper and lower ends, and the outer sides of the two damping rods are connected to the first cleaning scrapers by buffer springs. The two damping rods have the same structure, the two first cleaning scrapers are semi-circular in shape, and the outer sides of the two first cleaning scrapers are attached to the inner sidewall of the sleeve.

[0008] Preferably, a single-rotation reciprocating screw has a water wheel connected through its outer end, and the diameter of the water wheel is larger than the diameter of the single-rotation reciprocating screw, and an suction head is correspondingly located on the outer side of the water wheel.

[0009] Preferably, the single-rotor reciprocating screw has a movable seat connected to its outer thread, and connecting rods are installed at both ends of the movable seat by screws. The two connecting rods are symmetrically arranged about the transverse center line of the movable seat. The outer ends of the two connecting rods are installed with second cleaning scrapers by screws. The two second cleaning scrapers are semi-circular in shape, and the outer sides of the two second cleaning scrapers are attached to the inner wall of the suction tube.

[0010] Compared with the prior art, the beneficial effects of the present invention are: (1) A cannula is set up. A cannula is nested on the outside of the suction tube, and a filter head is set at the outer end of the cannula. At the same time, a suction head is corresponding to the inner side of the filter head. When the suction head performs abdominal suction, the filter head set at the outer end of the cannula will isolate the suction tube, so as to avoid the suction head causing suction injury to the greater omentum of the patient due to improper operation during abdominal suction. This can maintain the stability of the laparoscopic suction device and improve the efficiency of subsequent surgery. (2) Setting limit rods, using slots at both ends of the outer end of the sleeve to slide through and install the limit rods, and then extending the two limit rods through the two first limit slots to the outer ends of the sealing plate. When the sleeve is quickly installed later, the two limit rods can be automatically extended through the two compression springs to the outer ends of the sealing plate, and then the sleeve can be quickly installed, which solves the problem that the traditional sleeve installation steps are very cumbersome. (3) Furthermore, a compression spring is provided. The compression spring is provided with slots at both ends of the sleeve. Then, a limit rod is connected to the outer end of the two compression springs. When the sleeve needs to be quickly disassembled and replaced, you only need to manually press the two limit rods to retract and move them, so that the two limit rods retract into the inside of the sleeve. Then, you can rotate the sleeve to quickly disassemble and replace it. It is more practical and saves more time and effort. (4) A cleaning scraper is provided. Damping rods are provided at both the upper and lower ends of the suction tube. A first cleaning scraper is connected to the outer end of each of the two damping rods through a buffer spring. At the same time, the outer sides of the two first cleaning scrapers are attached to the inner wall of the sleeve. When the sleeve is installed on the outside of the suction tube, the two first cleaning scrapers will clean and scrape the inner wall of the sleeve. When the sleeve is disassembled and pulled out, the two first cleaning scrapers will also clean and scrape the impurities adhering to the inner wall of the sleeve, so as to avoid impurities adhering to the inner wall of the sleeve and affecting the subsequent use of abdominal suction, and to avoid the phenomenon of bacterial growth on the inner wall of the sleeve. (5) A single-rotation reciprocating screw is provided. The single-rotation reciprocating screw is installed inside the suction tube through a positioning frame bearing. A water wheel is installed at the outer end of the single-rotation reciprocating screw. When the suction tube is used to suction the abdominal cavity through the suction head, the potential energy of the suctioned liquid will drive the single-rotation reciprocating screw to rotate. At this time, the movable seat connected by the thread on the outer side of the single-rotation reciprocating screw will drive the two second cleaning scrapers to move back and forth through the two connecting rods. At this time, the two second cleaning scrapers will clean the impurities adhering to the inner wall of the suction tube in a cycle, so as to avoid the impurities adhering to the inner wall of the suction tube and affecting the stable absorption and use of the laparoscopic suction device in the later stage, thus improving the service life of the laparoscopic suction device.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] This invention provides the following technical solution: Example 1: To address the issue that existing laparoscopic aspirators lack protective devices to safeguard the suction tube 6 and suction head 7 during abdominal aspiration, thus preventing damage to the patient's greater omentum during suction, the following method is disclosed: The valve body 1 has a grooved and sealed connecting pipe 4 installed through it on its right end, and a sealing plate 5 is installed through it on the outer end of the connecting pipe 4. It also includes: a valve body 1, with a discharge pipe 8 installed through its left end, the discharge pipe 8 having the same diameter as the suction pipe 6, and a movable handle 3 installed at the top of the valve body 1, while a positioning rod 2 is installed at the bottom of the valve body 1, a sealing plate 5, with a suction pipe 6 installed through its outer side, and a suction head 7 connected through its outer end, while the suction head 7 is in an inclined shape. The sealing plate 5 has a sleeve 9 installed through its outer end, and a suction tube 6 is correspondingly installed on the inner side of the sleeve 9. A filter head 10 is provided at the outer end of the sleeve 9, and a suction head 7 is correspondingly installed on the inner side of the filter head 10. The diameter of the sleeve 9 is larger than the diameter of the suction tube 6. The suction tube 6 has a positioning frame 18 installed with a slotted screw inside. A single-turn reciprocating screw 19 is installed through the slotted part of the positioning frame 18 via a bearing. The positioning frame 18 is hollow, and the single-turn reciprocating screw 19 is rotatably installed inside the suction tube 6.

[0015] The sleeve 9 has two limiting rods 11 that are slidably installed through the grooves inside its outer end. The two limiting rods 11 are symmetrically arranged about the vertical center line of the sleeve 9. Both limiting rods 11 extend through the first limiting grooves 12 to the outer ends of the sealing plate 5. The two first limiting grooves 12 are symmetrically opened at both ends of the sealing plate 5. The sealing plate 5 has second limiting grooves 13 at both its upper and lower ends, and the two second limiting grooves 13 are the same size.

[0016] The sleeve 9 has slots at both ends inside, and the two compression springs 14 have the same structure. The outer ends of the two compression springs 14 are connected to limit rods 11.

[0017] like Figures 1-5 As shown, when a laparoscopic aspirator is needed to perform abdominal suction on a patient, and the suction head 7 at the outer end of the suction tube 6 needs to be protected, simply put the sleeve 9 on the outside of the suction tube 6 so that the outer end of the sleeve 9 extends through the inside of the sealing plate 5. At this time, the two compression springs 14 will automatically pop out the two limiting rods 11 through the two first limiting grooves 12 to the outer ends of the sealing plate 5 through their own elastic force. This can fix the installed sleeve 9 in place, preventing the sleeve 9 from loosening and falling off during later use. The filter head 10 at the outer end of the sleeve 9 can isolate the suction tube 6, preventing the suction head 7 from causing suction injury to the patient's greater omentum due to improper operation during abdominal suction, thus improving the safety of using the laparoscopic aspirator. When the sleeve 9 needs to be quickly disassembled and replaced, simply press the two limiting rods 11 manually to retract and move them into the sleeve 9. Then, manually rotate the sleeve 9 to separate the sealing plate 5 from the sleeve 9, and the sleeve 9 can be quickly disassembled and replaced. Finally, the elastic force of the two compression springs 14 can be used to elastically reset the two compressed limiting rods 11, so that the two limiting rods 11 extend from the second limiting groove 13 to the outside of the sealing plate 5. This makes it more practical and saves more time and effort.

[0018] Example 2 differs from Example 1 in that it allows for the cleaning and scraping of adhering impurities on the inner wall of the sleeve 9, preventing impurities from sticking to the inner wall of the sleeve 9 and causing bacterial growth, thus improving the hygiene of the sleeve 9. The following is disclosed: The suction tube 6 has damping rods 15 screwed on at both ends. The outer sides of the two damping rods 15 are connected to the first cleaning scrapers 16 by buffer springs 17. The two damping rods 15 have the same structure. The two first cleaning scrapers 16 are semi-circular in shape, and the outer sides of the two first cleaning scrapers 16 are attached to the inner wall of the sleeve 9.

[0019] like Figures 1-7 As shown, when the sleeve 9 is installed through the outside of the suction tube 6, the damping rods 15 at the upper and lower ends of the suction tube 6 will press the two first cleaning scrapers 16 together with the inner wall of the sleeve 9 through the buffer springs 17. While the sleeve 9 is being inserted and moved, the two first cleaning scrapers 16 can move and clean the inner wall of the sleeve 9. It can also clean and scrape sleeves 9 of different diameters. Then, when the sleeve 9 is pulled out and reset, the two first cleaning scrapers 16 will also move and clean the inner wall of the sleeve 9 through the two buffer springs 17. This prevents impurities from sticking to the inner wall of the sleeve 9 and causing bacterial growth, thus improving the hygiene of the sleeve 9.

[0020] Example 3 differs from Example 2 in that, during abdominal suction via the suction head 7, the two second cleaning scrapers 23 can be driven to repeatedly clean the inner wall of the suction tube 6, preventing impurities from adhering to the inner wall of the suction tube 6 and affecting subsequent suction use, thus improving the service life of the suction tube 6. The following is disclosed: A single-turn reciprocating screw 19 has a water wheel 20 connected through its outer end. The diameter of the water wheel 20 is larger than the diameter of the single-turn reciprocating screw 19. A suction head 7 is located on the outer side of the water wheel 20. A movable seat 21 is threaded through the outer side of the single-turn reciprocating screw 19. Connecting rods 22 are installed at both the upper and lower ends of the movable seat 21 by screws. The two connecting rods 22 are symmetrically arranged about the transverse center line of the movable seat 21.

[0021] The outer ends of the two connecting rods 22 are each fitted with a second cleaning scraper 23 by screws. Both second cleaning scrapers 23 are semi-circular in shape, and the outer sides of both second cleaning scrapers 23 are attached to the inner sidewall of the suction tube 6.

[0022] like Figures 1-10 As shown, when the suction tube 6 suctions the abdominal cavity through the suction head 7, the suctioned liquid will drive the single-rotor reciprocating screw 19, which is connected to the inner end of the water wheel 20, to rotate through its own flow potential energy. At this time, the rotating single-rotor reciprocating screw 19 will drive the moving seat 21 to move back and forth in the left and right position. Thus, the two connecting rods 22 can drive the two second cleaning scrapers 23 to move back and forth in the left and right position to scrape the inner wall of the suction tube 6, so as to avoid the suctioned liquid impurities from sticking to the inner wall of the suction tube 6 and causing blockage, thereby improving the service life of the suction tube 6 and completing a series of tasks.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
