Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a laparoscope separation and flushing device for preventing tissue adhesion in gynecological surgery. Background Art

[0002] The laparoscopic separation and irrigation device, used to prevent tissue adhesion during gynecological surgery, is a precision instrument specifically designed for laparoscopic surgery, integrating multiple functions such as separation and irrigation. During surgery, when the doctor needs to separate tissue, the tip of the separation and irrigation device can accurately peel off the adhered tissue. Its design is generally more sophisticated, which can reduce damage to surrounding normal tissue. At the same time, it also has a flushing function. Through the built-in channel, it can continuously spray irrigation fluids such as saline into the surgical area. On the one hand, this can promptly flush away blood clots and tissue debris generated during surgery, maintaining a clear surgical field of view and facilitating the doctor's operation. On the other hand, the irrigation fluid can form a liquid barrier on the surface of the separated tissue, effectively reducing direct contact between tissues, thereby reducing the probability of postoperative tissue adhesion and ensuring the patient's postoperative recovery.

[0003] In traditional gynecological surgeries, doctors often rely on specialized instruments to clamp and secure the tissues to prevent abnormal adhesions. However, this clamping procedure has a significant limitation: once the tissue is clamped, the instruments themselves often lack additional stabilizing devices. This requires the doctor to maintain a firm handhold to perform other necessary surgical steps while or after clamping the tissue. This not only greatly increases the difficulty and complexity of the surgical procedure, prolonging the operation time, but also increases the doctor's skill and physical strength, limiting the smoothness and efficiency of the operation. Summary of the Invention

[0004] One purpose of the present invention is to propose a laparoscopic separation and irrigator for preventing tissue adhesion in gynecological surgery. The present invention solves the problem raised in the above background that once the tissue is clamped, the instrument used for clamping itself often lacks additional stable fixing devices, which causes the doctor to continue to hold the instrument firmly with his hands in order to perform other necessary surgical steps while or after clamping the tissue. This not only greatly increases the difficulty and complexity of the surgical operation and prolongs the operation time, but also invisibly increases the requirements for the doctor's operating skills and physical strength, limiting the fluency and efficiency of the operation.

[0005] A laparoscopic separation and irrigating device for preventing tissue adhesion in gynecological surgery according to an embodiment of the present invention comprises:

[0006] A protective shell, used to protect the clamping mechanism, the flushing mechanism, the first positioning mechanism and the second positioning mechanism inside the protective shell;

[0007] The clamping mechanism includes a clamping plate and a telescopic column, the telescopic column is movably connected to the inside of the protective shell, one end of the telescopic column is fixedly connected to a connecting block via a connecting rod, both sides of the connecting block are movably connected to a rotating rod via a transmission rod, and the clamping plate is rotatably mounted on one end of the rotating rod via a rotating structure;

[0008] The first positioning mechanism includes a clamping block movably connected to the outer surface of the telescopic column;

[0009] The second positioning mechanism includes a positioning ring, an insert block and a slot. The positioning ring is movably connected to the outside of the protective shell. Both side surfaces of the positioning ring are fixedly connected with positioning plates. The insert block is movably connected to one side surface of the positioning plate. The slot is opened on the outer surface of the protective shell.

[0010] Preferably, one end of the telescopic column away from the connecting rod is fixedly connected to a first handle.

[0011] Preferably, a return spring is installed between one side of the telescopic column and one side of the interior of the protective shell, and the return spring is arranged on the surface of the connecting rod.

[0012] Preferably, one end of the transmission rod is rotatably connected to one side of the connecting block, the other end of the transmission rod is rotatably connected to the side surface of the rotating rod, and the end of the rotating rod away from the clamping plate is rotatably mounted on one end of the protective shell.

[0013] Preferably, a groove is formed on the side surface of the telescopic column, and the clamping block is movably installed inside the groove via a first positioning spring.

[0014] Preferably, the flushing mechanism includes a water supply pipe and an elliptical block, the water supply pipe is fixedly installed on the inner side of the protective shell, one end of the water supply pipe is fixedly connected to the water injection pipe, and the other end of the water supply pipe is fixedly connected to the nozzle.

[0015] Preferably, an adjustment groove is provided on the side surface of the protective shell, and the elliptical block is rotatably connected inside the adjustment groove.

[0016] Preferably, the card slots are provided in a plurality of groups, and the plurality of card slots are arranged in a linear array on the outer surface of the protective shell.

[0017] Preferably, a movable block is slidably connected to one side surface of the positioning plate, the inserting block is fixedly connected to one side surface of the movable block, and a second handle is fixedly connected to the other side surface of the movable block.

[0018] Preferably, both sides of the surface of the positioning plate are fixedly connected with fixed plates, both side surfaces of the movable block are fixedly connected with baffles, and a second positioning spring is installed between the baffle and the fixed plate.

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a first positioning mechanism and a clamping mechanism. When the device is used to clamp human tissue in gynecological surgery, the telescopic column is stretched backward by the first handle. After the telescopic column is stretched outward, the connecting block is driven to slide backward through the connecting rod. The connecting block pulls the middle part of the rotating rods on both sides through the transmission rod, so that the rotating rods on both sides rotate synchronously toward the middle, thereby causing the clamping plate connected to one end of the rotating rod to be squeezed toward the middle by the rotating structure. After the tissue is clamped and fixed by the clamping plate, the reset spring is in a stretched state. At the same time, the clamping block of the first positioning mechanism is pulled out of the protective shell, and the first positioning spring inside the groove pops out of the groove and is clamped in the outer end of the protective shell, so that the device can clamp and fix the human tissue. In the current state, the doctor can keep the device fixed on the tissue even if he releases his hands, freeing his hands, simplifying the operation, and reducing the difficulty of the operation.

[0021] The flushing mechanism of the present invention can inject flushing liquid through the water injection pipe while clamping the tissue, and flush the tissue through the water supply pipe and the nozzle. The elliptical block can be manually rotated as needed. When the longer diameter section of the elliptical block is perpendicular to the water supply pipe, the water supply pipe is squeezed, thereby reducing the water flow in the water supply pipe and reducing the flushing force. When the shorter diameter section of the elliptical block is perpendicular to the water supply pipe, the water supply pipe is in a maximum water flow state, thereby increasing the flushing force. The flushing force can be flexibly controlled to ensure a clear field of vision and effectively prevent adhesion.

[0022] The present invention provides a second positioning mechanism. When performing gynecological surgery, the positioning ring and positioning plate of the second positioning mechanism are attached to the outside of the patient's skin, thereby achieving control of the length of the entire device in the patient's body. When the device is inserted into the patient's subcutaneous tissue for surgery, the positioning ring and positioning plate are first attached to the part of the patient where surgery is required through surgical tape, and then the second handle is pulled outward to make the movable block and the insertion block slide outward, and the second positioning spring is compressed. When the device needs to be stationary after completing tasks such as clamping tissue, the second handle is released, and the resetting effect of the second positioning spring pushes the baffle, movable block and insertion block toward the direction of the card slot, so that the insertion block is stuck inside the card slot, thereby locking the position of the protective shell inside the positioning ring, preventing displacement during surgery, ensuring surgical safety, and improving operational stability.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0033] refer to Figure 1-7, a laparoscopic separation and irrigating device for preventing tissue adhesion in gynecological surgery, including the following embodiments:

[0034] Example 1:

[0035] A laparoscopic separation and irrigating device for preventing tissue adhesion in gynecological surgery, comprising a protective shell 1, a clamping mechanism 2, a flushing mechanism 3, a first positioning mechanism 4, and a second positioning mechanism 5 for protecting the interior of the protective shell 1; the clamping mechanism 2 comprises a clamping plate 209 and a telescopic column 201, the telescopic column 201 is movably connected to the interior of the protective shell 1, one end of the telescopic column 201 is fixedly connected to a connecting block 204 via a connecting rod 203, and both sides of the connecting block 204 are movably connected to a rotating rod 207 via a transmission rod 206, and the clamping plate 209 is fixedly connected to the connecting block 204 via a connecting rod 203. 9 is rotatably mounted on one end of the rotating rod 207 through the rotating structure 208; the end of the telescopic column 201 away from the connecting rod 203 is fixedly connected to the first handle 202, and a return spring 205 is installed between one side of the telescopic column 201 and the inner side of the protective shell 1. The return spring 205 is set on the surface of the connecting rod 203, one end of the transmission rod 206 is rotatably connected to one side of the connecting block 204, and the other end of the transmission rod 206 is rotatably connected to the side surface of the rotating rod 207. The end of the rotating rod 207 away from the clamping plate 209 is rotated. The device is installed at one end of the protective housing 1. Through the first positioning mechanism 4 and the clamping mechanism 2, when the device is used to clamp human tissue in gynecological surgery, the telescopic column 201 is stretched backward through the first handle 202, so that the telescopic column 201 is stretched outward and then the connecting block 204 is driven to slide backward through the connecting rod 203. The connecting block 204 pulls the middle part of the rotating rods 207 on both sides through the transmission rod 206, so that the rotating rods 207 on both sides rotate synchronously toward the middle, thereby rotating the rotating rod 207 connected to the rotating rod 207 through the rotating structure 208. 07 The clamping plate 209 at one end is squeezed toward the middle. After the tissue is clamped and fixed by the clamping plate 209, the reset spring 205 is in a stretched state. At the same time, the clamping block 403 of the first positioning mechanism 4 is pulled out of the protective shell 1, and the first positioning spring 402 inside the groove 401 pops out of the groove 401 and is stuck in the outer end of the protective shell 1, thereby realizing the clamping and fixing of the human tissue by the device. In the current state, the doctor can keep the device fixing the tissue even if he releases his hands, freeing his hands, simplifying the operation, and reducing the difficulty of the operation.

[0036] Example 2:

[0037] The first positioning mechanism 4 includes a block 403, which is movably connected to the outer surface of the telescopic column 201; a groove 401 is provided on the side surface of the telescopic column 201, and the block 403 is movably installed in the inside of the groove 401 through the first positioning spring 402. The flushing mechanism 3 includes a water supply pipe 302 and an elliptical block 305. The water supply pipe 302 is fixedly installed on the inner side of the protective shell 1, one end of the water supply pipe 302 is fixedly connected to the water injection pipe 301, and the other end of the water supply pipe 302 is fixedly connected to the nozzle 303. The side surface of the protective shell 1 is provided with an adjustment groove 304, and the elliptical block 305 is rotatably connected to the inner side of the adjustment groove 304. The flushing mechanism 3 is provided, and the flushing liquid can be injected through the water injection pipe 301 while the tissue is clamped, and the tissue is flushed through the water supply pipe 302 and the nozzle 303. The elliptical block 305 can be manually rotated as needed. When the longer diameter section of the elliptical block 305 is perpendicular to the water supply pipe 302, the water supply pipe 302 is squeezed, thereby reducing the water flow in the water supply pipe 302 and reducing the flushing force. When the shorter diameter section of the elliptical block 305 is perpendicular to the water supply pipe 302, the water supply pipe 302 is in a maximum water flow state, thereby increasing the flushing force, and flexibly controlling the flushing force to ensure a clear field of vision and effectively prevent adhesion.

[0038] Example 3:

[0039] The second positioning mechanism 5 includes a positioning ring 501, an insert block 504 and a slot 505. The positioning ring 501 is movably connected to the outer side of the protective shell 1. The two side surfaces of the positioning ring 501 are fixedly connected to the positioning plate 502. The insert block 504 is movably connected to one side surface of the positioning plate 502. The slot 505 is opened on the outer surface of the protective shell 1. The slot 505 is provided in a plurality of groups. The plurality of groups of slots 505 are linearly arrayed on the outer surface of the protective shell 1. A movable block 503 is slidably connected to one side surface of the movable block 503 on one side surface of the movable block 503. A second handle 509 is fixedly connected to the other side surface of the movable block 503. Fixed plates 507 are fixedly connected to both sides of the surface of the positioning plate 502. Baffles 506 are fixedly connected to both sides of the surface of the movable block 503. A second positioning spring 508 is installed between the baffle 506 and the fixed plate 507. When performing gynecological surgery, the positioning ring 501 and the positioning plate 502 of the second positioning mechanism 5 are attached to the outside of the patient's skin, thereby controlling the length of the entire device in the patient's body. When the device is inserted into the patient's subcutaneous tissue for surgery, the positioning ring 501 and the positioning plate 502 are first attached to the part of the patient where surgery is required through surgical tape, and then the second handle 509 is pulled outward to make the movable block 503 and the inserting block 504 slide outward, and the second positioning spring 508 is compressed. When the device needs to be stationary after completing tasks such as clamping tissue, the second handle 509 is released, and the baffle 506, the movable block 503 and the inserting block 504 are pushed toward the direction of the card slot 505 by the reset effect of the second positioning spring 508, so that the inserting block 504 is stuck inside the card slot 505, thereby locking the position of the protective shell 1 inside the positioning ring 501, preventing displacement during surgery, ensuring surgical safety, and improving operational stability.

[0040] At the beginning of the operation, the doctor first fixes the protective shell 1 of the device to the predetermined surgical site on the patient's body surface through the positioning ring 501 and the positioning plate 502 at its outer end using surgical tape. Then, the doctor holds the first handle 202 and pulls the telescopic column 201 backward. As the telescopic column 201 is stretched outward, it overcomes the elastic force of the return spring 205 and drives the connecting block 204 to slide backward through the connecting rod 203. The transmission rods 206 on both sides of the connecting block 204 move accordingly. They are connected to the middle part of the rotating rod 207. This will synchronously pull the rotating rods 207 on both sides to rotate toward the middle. One end of the rotating rod 207 is connected to the clamping plate 209 through the rotating structure 208. The rotation of the rotating rod 207 directly causes the clamping plate 209 to move closer to the middle and squeeze, so that the human tissue to be processed can be firmly clamped and fixed. In the process of clamping the tissue, the return spring 205 is stretched and stored. At the same time, the action of the clamping mechanism 2 also links the first positioning mechanism 4: the movement of the telescopic column 201 causes the block 403 to be pulled out of the recessed space on the side of the protective shell 1 The clamping plate 209 is pressed against the outer edge of the protective shell 1 and the clamping plate 209 is pressed against the outer edge of the protective shell 1. The clamping plate 209 is pressed against the outer edge of the protective shell 1 and the clamping plate 209 is pressed against the outer edge of the protective shell 1. The clamping plate 209 is pressed against the outer edge of the protective shell 1 and the clamping plate 209 is pressed against the outer edge of the protective shell 1. The clamping plate 209 is pressed against the outer edge of the protective shell 1 and the clamping plate 209 is pressed against the outer edge of the protective shell 1. The other end of the water injection pipe 301 is connected to the nozzle 303. The flushing liquid is transported to the nozzle 303 through the water supply pipe 302 and sprayed on the surgical area to flush away blood clots and tissue debris, maintain a clear field of vision, and form a liquid barrier to prevent adhesions. The doctor can control the flushing force by rotating the elliptical block 305 rotating in the adjustment groove 304 on the side surface of the protective shell 1. When the longer diameter section of the elliptical block 305 rotates to be perpendicular to the water supply pipe 302, it will squeeze the water supply pipe 302, increase the water flow resistance, and reduce the flushing force.On the contrary, when the shorter diameter section of the elliptical block 305 is perpendicular to the water supply pipe 302, the water supply pipe 302 is unobstructed and the flushing force reaches the maximum. This design allows the doctor to flexibly adjust the flushing intensity according to actual needs. When the device needs to be stabilized at a certain depth for operation, the second positioning mechanism 5 plays a key role. After inserting the protective shell 1 to the required depth, the doctor holds the second handle 509 on the side of the positioning plate 502 and pulls it outward. This action drives the movable block 503 and the plug block 504 fixed thereon to slide outward together, and at the same time compresses the second positioning spring 508 between the baffle 506 and the fixed plate 507. When the position of the device is adjusted When the ring 501 is in place and needs to be fixed, the doctor releases the second handle 509. Under the return force of the second positioning spring 508, the baffle 506 pushes the movable block 503 and the insert block 504 inward. The insert block 504 accurately slides into and is locked in one of the multiple groups of slots 505 pre-defined on the outer surface of the protective shell 1. The insertion of the insert block 504 into the slot 505 firmly locks the position of the positioning ring 501, preventing it from accidentally moving during the surgical operation, ensuring the accuracy and safety of the operation and improving the stability of the overall operation. The entire process combines the functions of clamping, locking, flushing, and depth positioning to collaboratively complete the surgical task.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
