Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an electrocoagulation irrigation and suction device for laparoscopy. Background Technology

[0002] The laparoscopic irrigation and aspiration device with electrocoagulation is a crucial medical instrument in laparoscopic surgery. It combines irrigation and aspiration functions with electrocoagulation. The irrigation function primarily cleans the surgical field by spraying sterile irrigation fluid, such as saline, into the surgical area. This helps remove blood, tissue debris, and other impurities from the surgical site, allowing the surgeon to more clearly observe the anatomical structures of the surgical area.

[0003] Currently, some traditional laparoscopic electrocoagulation irrigation and aspiration devices are prone to clogging at the irrigation end during use. This clogging can lead to increased water pressure and leakage in the connected water inlet tube, making them inconvenient to use. Some existing disposable laparoscopic electrocoagulation irrigation and aspiration devices do not leak during use, but they are disposable and have high operating costs. Therefore, this solution proposes a new laparoscopic electrocoagulation irrigation and aspiration device. Utility Model Content

[0004] In order to improve the problems of easy blockage at the irrigation end and easy leakage at the water injection pipe connection of traditional electrocoagulation irrigation and aspiration devices during use, this application provides an electrocoagulation irrigation and aspiration device for laparoscopy.

[0005] The laparoscopic electrocoagulation irrigation and suction device provided in this application adopts the following technical solution:

[0006] A laparoscopic electrocoagulation and aspiration device includes an aspirator body and a tubing. A water inlet connector A is fixedly connected to one side of the aspirator body, and an electrical connector is fixedly installed on the side surface of the aspirator body. A connecting assembly is provided on one side of the aspirator body at the water inlet connector A. The connecting assembly includes a water storage box fixedly connected to the side surface of the aspirator body. A fixing plate is fixedly connected to the bottom of the water storage box. A limiting hole is opened in the middle of the top of the fixing plate. A movable plate moves through the limiting hole. Protrusions for engaging with the fixing plate are provided on both sides of the end of the movable plate. A pushing block is fixedly connected to the lower part of one end of the movable plate, and a squeezing block is symmetrically fixedly connected to the lower part of the other end of the movable plate. A limiting tube is fixedly connected to the top of the movable plate near the pushing block.

[0007] A water inlet connector B is fixedly connected to the lower side of the water storage box. The end of the water inlet connector B is sleeved on the inner ring surface of the hose, and the outer ring surface of the hose is sleeved on the inner ring of the limiting tube.

[0008] Preferably, the water storage box has an insertion hole for connecting the water injection connector A on the side away from the aspirator body.

[0009] Preferably, the water injection connector B is conical in shape, and the inner ring surface of the limiting tube is conical.

[0010] Preferably, a connecting pipe is fixedly connected to one side of the water storage box, and the end of the connecting pipe movably passes through a limiting post. A piston A is fixedly connected to one end of the limiting post, and a pressing block is fixedly connected to the other end of the limiting post.

[0011] Preferably, a compression spring A is fitted on the outer peripheral surface of the limiting post, with one end abutting against the piston A and the other end abutting against the connecting pipe.

[0012] Preferably, a water injection pipe is fixedly connected to the end of the suction body. One end of the water injection pipe has a threaded groove and a flushing head assembly is provided at one end of the water injection pipe. The flushing head assembly includes an injection head that abuts against the end of the water injection pipe. Multiple water outlet holes are equidistantly provided on the outer circumferential surface of the injection head. A threaded groove is provided at the end of the injection head near the water injection pipe.

[0013] Preferably, a limiting rod is fixedly connected to the end of the injection head away from the water injection pipe, and a piston B is movably passed through the limiting rod. A compression spring B is sleeved on the outer circumferential surface of the limiting rod, with one end abutting against the injection head and the other end abutting against the piston B. The end of the injection head away from the water injection pipe is arc-shaped, and a rubber ring is threadedly installed at the end of the injection head near the water injection pipe. The other end of the rubber ring is threadedly connected to one end of the water injection pipe.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. By directly installing a water storage box at the water inlet A on the side of the suction device body, the problem of water leakage at the water inlet A during each use can be directly solved. Then, a movable limiting tube corresponding to the water inlet B is installed on the bottom plate of the water storage box. The limiting tube strengthens the connection between the hose and the water inlet B, preventing water leakage at the joint and achieving a leak-proof effect.

[0016] 2. By installing a manual water pressure control device on the water storage box, the piston A is moved by squeezing the pressing block, which changes the water pressure in the water storage box, thereby controlling the position of the piston B in the injection head, and thus controlling the water flow pressure and the number of water outlets on the injection head, thereby achieving the anti-clogging effect.

[0027] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0028] This application discloses an electrocoagulation irrigation and suction device for laparoscopy.

[0029] Reference Figure 1 ,and Figure 2 As shown, a laparoscopic electrocoagulation aspirator includes an aspirator body 1 and a hose 4. A water inlet connector A101 is fixedly connected to one side of the aspirator body 1, and an electrical connector 102 is fixedly installed on the side of the aspirator body 1. A connecting component 2 is provided on one side of the aspirator body 1 at the water inlet connector A101. The connecting component 2 includes a water storage box 201 that is bonded to the side surface of the aspirator body 1. The water storage box 201 is made of transparent plastic material.

[0030] Reference Figure 3 ,and Figure 4 , Figure 5 and Figure 6 As shown, a fixing plate 209 is fixedly connected to the bottom of the water storage box 201 at the end away from the hose 4. A limiting hole 2090 is opened in the middle of the top of the fixing plate 209, and a movable plate 210 moves through the limiting hole 2090. Protrusions for engaging and fixing the movable plate 210 to the fixing plate 209 are provided on both sides of the end of the movable plate 210. A pushing block 211 is fixedly connected to the lower part of the movable plate 210 away from the hose 4. The pushing block 211 is used to adjust the moving position of the movable plate 210. A pressing block 212 is symmetrically fixedly connected to the lower part of the movable plate 210 away from the movable plate 210. The pressing block 212 is also used to adjust the moving position of the movable plate 210. One end of the movable plate 210 is fixedly connected above the pushing block 211. When the limiting tube 213 is pressed, the protrusions on both sides of the moving plate 210 will move from the inside of the fixed plate 209 to one end of the fixed plate 209. When the pressing block 212 is pressed, the gap between the two ends of the moving plate 210 can be changed, so that the protrusions on both sides of the moving plate 210 will be inserted back into the fixed plate 209. A water inlet connector B208 is fixedly connected to the lower side of the water storage box 201. The end of the water inlet connector B208 is sleeved with the inner ring surface of the hose 4. When the hose 4 is connected to the water inlet connector, the end will be opened. The outer ring surface of the opened hose 4 will abut against the inner ring of the limiting tube 213. When the limiting tube 213 is moved, the hose 4 can be squeezed, increasing the connection strength between the hose 4 and the water inlet connector B208.

[0031] Reference Figure 3 As shown, the water storage box 201 has an insertion hole 202 on the side away from the suction body 1. The insertion hole 202 is inserted into the water injection connector A101, and the diameter of the insertion hole 202 is the same as that of the water injection connector A101. The water injection connector B208 is generally conical, which can open the hose 4 sleeved on the water injection connector B208 to increase the connection strength. The inner ring surface of the limiting tube 213 is conical, which is used to fit the opened hose 4 and improve the fit with the surface of the hose 4 during subsequent reinforcement and tightening.

[0032] Reference Figure 3As shown, a connecting pipe 203 is fixedly connected to one side of the water storage box 201. The end of the connecting pipe 203 movably passes through a limiting post 204. A piston A205 is fixedly connected to one end of the limiting post 204. When liquid is injected into the water storage box 201, the water pressure will squeeze the piston A205, thereby driving the limiting post 204 to move towards one end of the connecting pipe 203, which will squeeze the compression spring A207. A pressing block 206 is fixedly connected to the other end of the limiting post 204. Subsequently, by manually pushing the pressing block 206, the compression spring A207 will be squeezed again, which can drive the piston A205 to move towards the other end of the connecting pipe 203, thereby changing the water pressure in the water storage box 201.

[0033] Reference Figure 6 As shown, a water injection pipe 103 is fixedly connected to the end of the suction body 1. One end of the water injection pipe 103 has a threaded groove, and a flushing head assembly 3 is provided at one end of the water injection pipe 103. The wiring terminal of the connector 102 passes through the pipe wall of the water injection pipe 103 and the pipe wall of the injection head 301, and is electrically connected to the wiring terminal of the handle or the outside, so that the external cable can control the operation of the connector 102 through the wiring terminal. The flushing head assembly 3 includes an injection head 301 that is connected to the end of the water injection pipe 103. The outer circumferential surface of the injection head 301 has at least three water outlet holes 3010 equidistantly arranged in annular pattern. The end of the injection head 301 near the water injection pipe 103 has a threaded groove, and the end of the injection head 301 away from the water injection pipe 103 is fixedly connected to a limit rod 302. A piston B303 is movably passed through the limit rod 302. Piston B303 is movably sleeved inside injection head 301, and piston B303 is located between two water outlet holes 3010. A compression spring B304 is sleeved on the outer peripheral surface of limit rod 302. One end of compression spring B304 abuts against injection head 301, and the other end of compression spring B304 abuts against piston B303. The end of injection head 301 away from water injection pipe 103 is arc-shaped. A rubber ring 305 is threadedly installed on the end of injection head 301 near water injection pipe 103. The other end of rubber ring 305 is threadedly connected to one end of water injection pipe 103. When the water pressure inside water injection pipe 103 is high, it will squeeze piston B303, which will squeeze compression spring B304, thereby allowing more water outlet holes 3010 to leak out and increasing drainage volume. With the adjustment of liquid water pressure in connecting pipe 203, injection head 301 can be prevented from being blocked.

[0034] The connection method between the connector 102 and the connecting wire and the external control equipment is a mature existing technology, so the specific connection relationship will not be described in detail. Existing connection assemblies can be installed for use.

[0035] The implementation principle of the laparoscopic electrocoagulation irrigation and suction device according to an embodiment of this application is as follows: First, one end of the injection tubing 4 is passed through the inner ring of the limiting tube 213. Then, the tubing 4 is inserted into the water injection connector B208 on the side of the water storage box 201. Since the water injection connector B208 is conical in shape, the front end of the water injection connector B208 is smaller than the inner diameter of the tubing 4, and the rear end of the water injection connector B208 is larger than the inner diameter of the tubing 4. This allows one end of the tubing 4 to be partially opened, increasing the connection strength. Because the inner ring surface of the limiting tube 213 is conical, the limiting tube 213 can be used to fit the opened tubing. At this time, by pressing the push block 211, the moving plate 210 and the limiting tube 213 are moved to one side. When the protruding blocks on both sides of the moving plate 210 are disengaged from the interior of the fixed plate 209 and move to one end of the fixed plate 209, the limiting tube 213 will also push the inner side and the attached hose 4 towards the water injection connector B208. At this time, the limiting tube 213 will be tightly attached to the outer surface of the hose 4 and form a squeezing force between it and the water injection connector B208, thereby reinforcing the connection between the hose 4 and the water injection connector B208 and preventing leakage after the water pressure increases.

[0036] Meanwhile, when water is supplied to the water storage box 201, the internal water pressure will push the piston A205 to one end, thereby causing the limiting post 204 and the pressing block 206 to move to one side. This will compress the compression spring A207 located on the limiting post 204. At this time, when the water flow rate of the hose 4 remains constant, the water pressure inside the water storage box 201 is fixed. When the water outlet 3010 on the injection head 301 is blocked during use, by quickly pressing the pressing block 206, the piston A205 is moved, and the compression spring A207 can quickly return to its original position, causing the water pressure inside the water storage box 201 to increase in a short time. When the water pressure in the water storage box 201 changes, the water pressure in the water injection pipe 103 also changes accordingly. The increased water pressure will squeeze the piston B303 to move on the limit rod 302 in the injection head 301, thereby squeezing the compression spring B304. This will expose more water outlet holes 3010, allowing for instantaneous adjustment of the water output and pressure of the water outlet holes 3010. This solves the problem of the injection head 301 being blocked during use, achieving the anti-blocking effect. Subsequently, the piston A205 will reset under the water pressure inside the water storage box 201, and at the same time, the piston B303 will reset under the action of the compression spring B304.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
