Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a flushing suction device with a telescopic hook. Background Technology

[0002] In surgical procedures, especially those involving blood vessels, such as vascular anastomosis and reconstruction, vascular traction and suture management are crucial steps. Currently, commonly used traction tools and suture manipulation tools are separate, requiring surgeons to frequently change tools during surgery. This not only increases surgical time but can also obstruct the surgical field of view, increasing surgical risks. Furthermore, existing traction tools struggle to precisely position the traction site behind the blood vessel and do not provide adequate protection for the vessel during traction. In suture manipulation, bringing the suture back from behind the blood vessel is cumbersome, and convenient and effective tools are lacking.

[0003] Irrigation aspirators are used during surgery to remove blood, tissue debris, and other contaminants from the surgical area, maintaining a clear surgical field. However, existing irrigation aspirators have limited functionality and cannot meet the needs of traction and suture manipulation.

[0004] It is important to note that tissue traction is a crucial step in various surgical procedures. Appropriate retractors effectively expose the surgical field, facilitating precise manipulation by the surgeon. Traditional tissue retractors have a relatively limited function, only capable of retrieving tissue. During surgery, if irrigation or suction of the surgical site is required, additional instruments are often needed. This not only increases the complexity of the procedure but may also prolong the operation time due to frequent instrument changes, increasing the risk of infection for the patient. Furthermore, in endoscopic surgeries, the retrieval and fixation of tissue are more challenging. Traditional retractors lack effective suture fixation structures, making it difficult to achieve stable retrieval and positioning of tissue within the cavity, thus affecting the smooth progress and outcome of the surgery. Utility Model Content

[0005] The purpose of this invention is to provide an irrigation and suction device with a telescopic hook, which can integrate multiple functions such as traction of blood vessels, fixation of sutures, and irrigation and suction, simplifying the surgical procedure and improving surgical efficiency and safety.

[0006] This utility model is achieved through the following technical solution:

[0007] A flushing suction device with a telescopic hook includes a handle assembly and a tubing assembly; the tubing assembly includes a flushing suction tube and an inner pull tube;

[0008] The handle assembly has a handle channel extending from the distal end to the proximal end, and the proximal end of the flushing suction tube is connected to the handle channel; so that the handle channel and the interior of the flushing suction tube are connected to form a sliding channel. The handle assembly is also equipped with a dial that can slide remotely and remotely, and the inner pull tube is located in the sliding channel and connected to the dial.

[0009] The proximal end of the inner pull tube extends into the proximal end of the handle assembly for connecting to an external rinsing / suction device; a hook connector is installed at the distal end of the inner pull tube, and the hook connector has a through-flow water outlet channel that connects the inner pull tube and the rinsing / suction tube; a telescopic hook is connected to the hook connector, and the telescopic hook is made of shape memory metal; the telescopic hook is provided with a suture hole and a suture pull opening;

[0010] The flushing suction tube has several flushing holes on its distal wall, and a fixing seat is also installed at the distal end of the flushing suction tube. The fixing seat has an outlet hole for the telescopic hook to pass through.

[0011] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0012] This utility model combines a telescopic hook with an irrigation and suction device to achieve multiple functions such as traction of blood vessels, fixation of sutures, and irrigation and suction, simplifying the surgical procedure and improving surgical efficiency and safety.

[0013] 2. The telescopic puller can both fix the suture by using the suture hole and the suture pull opening, and it can also use its own curved hook structure to hook the target object to achieve the effect of pulling blood vessels.

[0014] 3. The telescopic hook is made of nickel-titanium alloy with memory function. When it retracts into the flushing suction tube and then extends again, it can restore its original arc structure and maintain its original function. It can be used to wrap around the back of the blood vessel to play a traction role. This design conforms to the physiological curve of human tissue, can fit the tissue better, reduce tissue damage, and more stably pull the blood vessel, reducing the risk of blood vessel slippage.

[0015] 4. The irrigation suction tube can promptly remove impurities and waste fluid from the surgical site, maintain a clear surgical field, and help doctors perform surgical operations more accurately. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0029] like Figures 1 to 11 As shown, a flushing suction device with a telescopic hook includes a handle assembly 1 and a tube assembly 2; the tube assembly 2 includes a flushing suction tube 20 and an inner pull tube 21.

[0030] The handle assembly 1 has a handle channel 10 extending from the distal end to the proximal end, and the proximal end of the flushing suction tube 20 is connected to the handle channel 10; so that the handle channel 10 and the interior of the flushing suction tube 20 are connected to form a sliding channel. The handle assembly 1 is also equipped with a dial 11 that can slide remotely and remotely, and the inner pull tube 21 is located in the sliding channel and connected to the dial 11.

[0031] The proximal end of the inner pull tube 21 extends out of the proximal end of the handle assembly 1 for connecting to an external rinsing / suction device; a hook connector 210 is installed at the distal end of the inner pull tube 21, and a water outlet channel 211 is provided on the hook connector 210, which connects the inner pull tube 21 and the rinsing / suction tube 20; a telescopic hook 3 is connected to the hook connector 210, and the telescopic hook 3 is made of shape memory metal material; the telescopic hook 3 is provided with a suture hole 30 and a suture pull opening 321 respectively;

[0032] The flushing suction pipe 20 has several flushing holes 201 on its far end wall. The far end of the flushing suction pipe 20 is also equipped with a fixing seat 4, which has an outlet hole 41 for the telescopic hook 3 to pass through.

[0033] It should be noted that the inner pull tube has a slender tubular structure, providing the necessary length and strength for the extension and retraction of the hook. Its structure is straight and slender, with slight diameter variations or structural adjustments in some areas to accommodate different functional requirements. The hook connector connects the telescopic hook and the inner pull tube, while the fixing base connects the telescopic hook and the irrigation / suction tube. Its various shapes ensure the overall structural stability. The through-slot of the hook connector connects the irrigation / suction tube and the inner pull tube. During surgery, the interface at the proximal end of the inner pull tube connects to external irrigation / suction equipment, enabling irrigation of the surgical site to remove blood, tissue fragments, and other impurities, maintaining a clear surgical field. It can also be used to aspirate irrigation fluid and surgical waste.

[0034] Furthermore, the shape memory metal material is a nickel-titanium alloy. The telescopic hook 3 includes a straight tube section 31 and a U-shaped curved tube section 32 connected to the distal end of the straight tube section 31; the suture perforation 30 is provided on the curved tube section 32;

[0035] The straight tube section 31 is connected to the hook connector 210. The side of the end of the curved tube section 32 has a groove, and both sides of the groove are provided with expansion protrusions 320; the two expansion protrusions 320 are spaced apart, so that the groove forms a suture pull opening 321 with an inverted T-shaped structure. The shrinkage suture perforation can be used to thread the suture, and the design of the suture pull opening facilitates the fixation of the suture during the pulling operation inside the cavity, thereby achieving stable pulling and positioning of the tissue.

[0036] Furthermore, the handle assembly 1 is provided with a sliding cavity 12 extending in the proximal direction;

[0037] The dial 11 includes a toggle part 110 disposed outside the handle assembly 1 and an insert part 111 embedded inside the handle assembly 1; the toggle part 110 is provided with a push protrusion 112, and slides are provided on both sides of the toggle part 110; the sliding cavity 12 is provided with a sliding groove structure that cooperates with the slides on both sides.

[0038] The embedded part 111 is provided with a dial channel 113 communicating with the handle channel 10. The section of the inner pull tube 21 extending into the dial channel 113 is connected to the embedded part 111 through a pin 5; so that when the dial 11 is pushed to slide near or far relative to the handle assembly 1, the inner pull tube 21 can move synchronously. The near part of the sliding cavity 12 is provided with a recessed area, and a limiting protrusion 120 is provided on the recessed area;

[0039] The bottom of the embedding part 111 is provided with a recessed area and a matching lower embedding structure, and the bottom of the lower embedding structure is provided with a mating limiting groove 115 that is recessed to the distal end, so that a wing with a certain elastic deformation capability is formed below the mating limiting groove 115. The bottom of the wing is provided with a main limiting groove 114 that mates with the limiting protrusion 120. The surface of the actuating part 110 is provided with a pattern to increase friction.

[0040] In the sliding connection structure between the dial 11 and the handle assembly 1, the main limiting groove 114 and the mating limiting groove 115 have a special structure. If only the main limiting groove 114 is provided without the mating limiting groove 115, after the main limiting groove 114 is inserted into the limiting protrusion 120, the entire dial 11 and the sliding cavity 12 in the handle assembly will easily form an interference fit, making it difficult for the dial 11 to move again. The mating limiting groove 115 can solve this structural defect well. With the mating limiting groove 115, a wing with a certain elastic deformation capability is formed below the mating limiting groove 115. At this time, if the main limiting groove 114 is inserted into the limiting protrusion 120, when the dial 11 is pushed, the space of the mating limiting groove 115 can allow the wing to be lifted upward by a certain angle, so that the main limiting groove 114 can more easily disengage from the limiting protrusion 120.

[0041] Furthermore, the tube assembly 2 also includes a plastic sleeve 22 covering the outer periphery of the flushing suction tube 20, with the proximal end of the plastic sleeve 22 connected to the distal end of the handle assembly 1. The plastic sleeve 22 serves to protect the flushing suction tube 20.

[0042] Furthermore, the proximal end of the flushing suction tube 20 is provided with an annular protrusion 200, and the handle channel 10 is provided with an annular groove 100 that cooperates with and connects to the annular protrusion 200.

[0043] Furthermore, the side of the hook connector 210 is flattened to form a water outlet channel 211.

[0044] The assembly process of this utility model is as follows: First, connect the telescopic hook 3, the hook connector 210 and the inner pull tube 21 together to form a telescopic whole. Then, connect the telescopic whole, the fixed base 4 and the flushing suction tube 20 together. Finally, disassemble the handle assembly 1, accurately install the structure that was just connected into the handle assembly 1, ensure that the position of the dial 11 is correct, and then reassemble the handle assembly 1 to ensure that all channels are unobstructed and the telescopic structure can work normally.

[0045] The application of this utility model in surgery is as follows:

[0046] ① Adjust the telescopic length and position of the telescopic hook 3 by adjusting the dial 11 according to the surgical site and operation requirements;

[0047] ② Suture fixation: Pass the suture through the suture hole 30, and use the suture pull tab 321 to pull and fix the tissue inside the cavity to ensure stable exposure of the tissue.

[0048] ③ Irrigation and suction: Connect the proximal end of the inner pull tube 21 to the irrigation fluid source and the negative pressure suction device, turn on the irrigation and suction functions, the irrigation fluid reaches the surgical site through the irrigation channel to irrigate the tissue; waste fluid and irrigation fluid can be suctioned out from the proximal end of the inner pull tube 21 to maintain a clear surgical field.

[0049] ④ Tissue retrieval: Operate the telescopic retractor 3, and use the curved tube section 32 of the telescopic retractor 3 to retrieve the tissue, expose the surgical field, and facilitate the doctor to perform subsequent surgical operations.

[0050] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
