Description

Technical Field

[0001] This utility model relates to the field of thyroid surgical instruments, and in particular to an endoscopic thyroid surgical dissection device. Background Technology

[0002] Endoscopic thyroid surgery involves making several small incisions in specific areas of the body (such as the areola, armpit, or mouth) to insert a scope and surgical instruments. The magnification and illumination of the scope provide a clear surgical view on a monitor, allowing the surgeon to operate and remove diseased thyroid tissue. In endoscopic thyroid surgery, the dissector is primarily used to separate the tissue surrounding the thyroid gland. Because the thyroid gland is located in the neck and surrounded by many important nerves, blood vessels, and organs, careful tissue separation is necessary to avoid damaging these structures. The dissector allows for precise tissue separation, providing a clear surgical field and ample operating space. During tissue separation, small blood vessel bleeding may occur. In such cases, the dissector can be used to stop the bleeding through pressure or in conjunction with other hemostatic instruments. For example, gently pressing the flat part of the dissector onto the bleeding point can provide temporary hemostasis.

[0003] During surgery, the surgeon uses hand twisting motions to ensure the precision of the dissector in tissue removal. Frequent hand twisting can put significant stress on the surgeon's hand muscles and joints, easily leading to hand fatigue. Over time, this may affect the surgeon's stability and endurance during the procedure. If the surgeon uses improper force or excessive speed during hand twisting, the dissector may vibrate or become unstable, increasing the risk of accidental damage to surrounding tissues. Furthermore, due to the unique shape and distribution of thyroid tissue, the dissector requires more precise angled rotation to achieve the desired dissection effect, placing high demands on the surgeon's technique as they hold surgical instruments in both hands. Utility Model Content

[0004] The purpose of this invention is to provide a laparoscopic thyroidectomy device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An endoscopic thyroidectomy device, comprising:

[0007] The handle is provided with a grip, and a support tube is provided at one end of the handle. A peeling pliers are provided at the end of the support tube away from the handle.

[0008] A pulling assembly, which is disposed inside a support tube, is used to pull the peeling clamps open and close;

[0009] A prying block is disposed on the outer surface of the support tube. The prying block linkage pulling component is used to adjust the rotation of the support tube, so that the peeling forceps can turn and accurately peel off the tissue.

[0010] Preferably, the handle is bent and has a groove that slides in contact with the outer surface of the grip.

[0011] Preferably, a first sleeve is fixedly disposed in the groove, a second sleeve is slidably connected to the outer surface of the first sleeve, and the end of the second sleeve is fixedly connected to the handle.

[0012] Preferably, the inner walls of sleeve one and sleeve two are provided with elastic elements.

[0013] Preferably, the pulling assembly includes a fixed cylinder, which is symmetrically fixedly disposed inside the support tube.

[0014] Preferably, the inner wall of the fixed cylinder is provided with a support rod, and the support rod is provided with symmetrical through grooves.

[0015] Preferably, the side of the through groove away from the handle is rotatably connected to the peeling pliers via a pivot.

[0016] Preferably, a fixing block is fixedly provided on the peeling clamp, and a pull rod is rotatably connected to the fixing block.

[0017] Preferably, the pulling assembly further includes a collar that is rotatably connected to the handle.

[0018] Preferably, the collar is symmetrically provided with locking blocks, the inner wall of the locking blocks passes through the outer surface of the pull rod, and the locking blocks are fixedly connected to the pull rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The pull assembly is controlled by a handle. When the pull assembly receives an operation signal, it transmits the pulling force to the dissecting forceps through a connected component. In the relaxed state, the dissecting forceps gradually close, grasping the thyroid tissue; in the pulling state, the dissecting forceps open, releasing the tissue. This opening and closing action can be precisely controlled according to the needs of the surgery.

[0021] By rotating the lever, the support tube rotates. Under the restraint of the locking block, the collar rotates, causing the pulling component to rotate synchronously. This easily allows for the adjustment of the dissecting forceps angle and the synchronized rotation of the pulling component. During surgery, the surgeon can quickly change the angle of the dissecting forceps by simply rotating the lever, avoiding arm fatigue caused by frequent wrist rotation. Furthermore, the restraining effect of the locking block makes the rotation of the collar and pulling component more precise, allowing the surgeon to accurately adjust the angle of the dissecting forceps according to surgical needs. This helps to better access and handle target tissue in complex surgical environments, improving surgical accuracy.

[0022] By using a pull assembly in conjunction with a lever to achieve synchronized rotation of the pull assembly, the dissector can better adapt to different surgical scenarios and patient conditions. Whether in confined spaces or facing complex tissue structures, it allows for flexible angle adjustments and operation, improving the instrument's adaptability. During surgery, surgeons no longer need to operate multiple components separately to achieve different functions. The coordinated use of the pull assembly and lever allows for a continuous adjustment of the dissector's angle and control of its opening and closing, significantly enhancing operational convenience.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0033] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0034] Please see Figures 1-5 A laparoscopic thyroidectomy dissector includes: a handle 1, a grip 2 on the handle 1, and a support tube 3 at one end of the handle 1, wherein the support tube 3 is rotatably connected to the handle 1, and a dissection forceps 304 is provided at the end of the support tube 3 away from the handle 1. During laparoscopic thyroid surgery, the surgeon holds the handle 1 with their palm and pinches the grip 2 with their fingers, inserting the laparoscopic thyroidectomy dissector into the surgical incision. The support tube 3 is used to deliver the dissection forceps 304 to the vicinity of the thyroid tissue. Then, the surgeon operates the grip 2 to control the opening and closing of the dissection forceps 304 to dissect the thyroid tissue.

[0035] An endoscopic thyroidectomy device further includes a pulling component housed within a support tube 3. The pulling component is used to open and close the dissecting forceps 304. During the procedure, the surgeon controls the pulling component via a handle 1. When the pulling component receives an operation signal, it transmits pulling force to the dissecting forceps 304 through a connected component. In the relaxed state, the dissecting forceps 304 gradually closes, grasping the thyroid tissue; in the pulling state, the dissecting forceps 304 opens, releasing the tissue. This opening and closing action can be precisely controlled according to the needs of the surgery.

[0036] An endoscopic thyroidectomy dissector further includes a lever 4, which is disposed on the outer surface of a support tube 3. The lever 4, linked to a pulling component, adjusts the rotation of the support tube 3, causing the dissector forceps 304 to turn and accurately dissect the tissue. During the procedure, the surgeon rotates the support tube 3 by levering the lever 4 with their thumb. This rotation causes the dissector forceps 304 to turn, allowing it to accurately align with the tissue to be dissected. The lever 4's design allows the surgeon to more precisely control the direction of the dissector forceps 304, achieving accurate dissection of the thyroid tissue. The direction of the dissector forceps 304 can be adjusted at any time according to the actual surgical situation, improving the accuracy and safety of the surgery.

[0037] It should be further explained that when lever 4 rotates, there is a certain amount of resistance between handle 1 and support tube 3. This resistance allows the surgeon to feel clear feedback when operating lever 4 to adjust the direction of the dissecting forceps 304. This feedback enables the surgeon to more accurately judge the degree of rotation of lever 4 and the turning angle of the dissecting forceps 304, thereby achieving more precise operational control. A certain amount of resistance can reduce accidental rotation of lever 4. During the operation, the surgeon's hand may inadvertently touch the instrument. If the resistance is too low, lever 4 can easily rotate accidentally, thus changing the direction of the dissecting forceps 304 and affecting the surgical progress. Setting a certain amount of resistance can reduce the possibility of such misoperation and ensure the stability and safety of the operation.

[0038] The handle 1 features a curved design that better conforms to the natural shape of the human hand, making it more comfortable for doctors to hold and reducing hand fatigue. During prolonged surgeries, this design improves the efficiency and precision of the surgeon's operation. A groove 11 is provided on the handle 1, which slides slidably onto the outer surface of the grip 2. By sliding the grip 2 within the groove 11, the pulling component actuates the dissecting forceps 304, allowing the surgeon to precisely control the opening and closing of the dissecting forceps 304 through subtle hand movements. This precise control is crucial for minimally invasive surgeries such as endoscopic thyroid surgery, reducing damage to surrounding tissues and improving surgical safety and success rates.

[0039] It should be noted that a sleeve 201 is fixedly installed inside the slide groove 11, and a sleeve 202 is slidably connected to the outer surface of the sleeve 201. The end of the sleeve 202 is fixedly connected to the handle 2. The inner walls of the sleeve 201 and the sleeve 202 are provided with elastic elements 203. The elastic elements 203 are used for resetting. When the doctor releases the handle 2, the squeezing force of the elastic element 203 disappears, causing the elastic element 203 to return to its original position, thereby enabling the dissecting forceps 304 to perform the operation of loosening or clamping tissue. The dimensions of the sleeve 201 and the sleeve 202 are matched with the elastic element 203 to avoid deformation of the elastic element 203 during operation.

[0040] Notably, the pulling assembly includes a fixed cylinder 301, which is symmetrically fixed within the support tube 3. The fixed cylinder 301 ensures that the pulling assembly will not loosen or shift during surgery, guaranteeing its reliability. A support rod 302 is mounted on the inner wall of the fixed cylinder 301, with symmetrical through slots 303 extending through it. The side of the through slot 303 furthest from the handle 2 is rotatably connected to the dissecting forceps 304 via a pivot. This pivot allows the dissecting forceps 304 to rotate within a certain angle range, enabling opening and closing actions. A fixed block 305 is fixedly mounted on the dissecting forceps 304, and a pull rod 306 is rotatably connected to the fixed block 305. When the surgeon needs to open the dissecting forceps 304 during surgery, they grasp the handle 2 and slide it within the groove 11. The pulling force generated by the sliding handle 2 is transmitted to the pull rod 306, which pulls the fixed block 305, thereby causing the dissecting forceps 304 to rotate around the pivot, achieving the opening action. When it is necessary to close the peeling clamp 304, release the handle 2 or slide the handle 2 in the opposite direction, and the pull rod 306 will be released through the transmission mechanism, so that the peeling clamp 304 can be closed.

[0041] Furthermore, the pulling assembly also includes a collar 307, which is rotatably connected to the handle 2. A locking block 309 is symmetrically arranged on the collar 307, the inner wall of which is penetrated by the outer surface of the pull rod 306, and the locking block 309 is fixedly connected to the pull rod 306. The locking mechanism 309 restricts the sliding force of the handle 2, which is then transmitted to the pull rod 306 to close the dissecting forceps 304. When it is necessary to change the angle of the dissecting forceps 304, the surgeon rotates the lever 4 with their thumb, causing the support tube 3 to rotate. At this time, under the restriction of the locking mechanism 309, the collar 307 rotates, and the pulling component rotates synchronously, easily realizing the angle change of the dissecting forceps 304 and the synchronous rotation of the pulling component. During the operation, the surgeon can quickly change the angle of the dissecting forceps 304 by simply rotating the lever 4, avoiding arm fatigue caused by frequent wrist rotation. In addition, the restriction of the locking mechanism 309 makes the rotation of the collar 307 and the pulling component more precise, allowing the surgeon to accurately adjust the angle of the dissecting forceps 304 according to the needs of the operation. This helps to better access and handle target tissue in complex surgical environments, improving the accuracy of the operation.
