Description

Technical Field

[0001] This invention relates to thyroid surgical techniques, and more particularly to a thyroid surgical dissection device. Background Technology

[0002] Thyroidectomy is a core surgical procedure for treating thyroid tumors, hyperthyroidism, and other diseases. The key challenge in this surgery lies in safely and completely separating the thyroid tissue from its surrounding critical structures, such as the recurrent laryngeal nerve, parathyroid glands, important blood vessels (such as the middle thyroid vein), and trachea.

[0003] Currently, most thyroid dissectors used clinically are fixed-angle, rigid rod-shaped instruments. Surgeons need to constantly change the bending angle of the dissector when separating different tissues, severely affecting the smoothness of the surgery and prolonging the operation time. Furthermore, secondary injury can occur when the dissector is inserted into or withdrawn from the incision site. With a fixed dissector, when dissecting the lateral side of the thyroid gland, especially when dealing with the thin-walled, easily torn thyroid middle vein, the end of the dissector is prone to almost vertically pressing against the vessel wall. Even slight carelessness can result in "puncturing" or "tearing" the vessel, leading to massive intraoperative bleeding. Simultaneously, when performing blunt dissection near the recurrent laryngeal nerve or parathyroid glands, the rigid structure of the dissector lacks buffering and feedback, making it impossible to detect the dissection force and contact force with the tissue. This can easily lead to excessive force by the surgeon, causing traction injuries and compression injuries to surrounding nerves, as well as damage to the delicate blood supply to the parathyroid glands, resulting in serious complications such as hoarseness and hypocalcemic tetany during and after surgery. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is: the problem that existing thyroid dissection devices are prone to causing traction injuries to surrounding nerves and damage to the delicate blood supply of the parathyroid glands due to excessive force exerted by the surgeon.

[0005] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a thyroid surgical removal device, which includes a handle including an operating handle, an installation cavity opened inside the operating handle, and a connecting tube connected to one side of the operating handle; The peeling part is located on one side of the handle and includes a connecting component sleeved on the outside of the connecting tube, a peeling head sleeved on the upper end of the inner periphery of the connecting component, an auxiliary head fixed on the lower end of the inner periphery of the connecting component, and a rotating component hinged to one side of the peeling head. The adjustment unit is located inside the mounting cavity and includes a turntable disposed in the mounting cavity, an adjustment rod connected to the inner side of the turntable, a piston rod sleeved on the inner side of the adjustment rod, and a transmission sleeve sleeved on the outer wall of the piston rod. The piston rod is connected to the rotating assembly via a transmission sleeve.

[0006] In a preferred embodiment of the thyroid surgical stripping device of the present invention: the connecting component includes a sleeve fixedly fitted around the outer periphery of the connecting tube, a snap ring protruding from one end of the sleeve, and a hinge joint fitted around the outside of the snap ring. The hinge joint is hinged to the stripping head and the auxiliary head at both ends, respectively.

[0007] In a preferred embodiment of the thyroid surgical dissection device of the present invention: the handle further includes a floral sleeve fitted onto the outside of the connecting tube.

[0008] In a preferred embodiment of the thyroid surgical dissection device of the present invention: the adjusting rod includes a driving section connected to the turntable, and a connecting section protruding from the end of the driving section; The connecting section is fixedly engaged with the piston rod.

[0009] In a preferred embodiment of the thyroid surgical dissection device of the present invention: the drive section includes straight grooves formed on both sides thereof; A transmission pin is slidably connected inside the straight groove.

[0010] In a preferred embodiment of the thyroid surgical removal device of the present invention: the transmission sleeve includes a piston cavity formed therein; The piston chamber is sealed to the outer wall of the piston rod to form a negative pressure driving space.

[0011] In a preferred embodiment of the thyroid surgical dissection device of the present invention: the rotating assembly includes a push rod slidably connected in the piston chamber, a connecting rod hinged to the end of the push rod, and a crank hinged to the other side of the connecting rod.

[0012] In a preferred embodiment of the thyroid surgical removal device of the present invention: the mounting cavity includes a guide groove formed on its inner wall, a receiving groove for embedding the turntable, and assembly holes provided on both sides of the receiving groove.

[0013] In a preferred embodiment of the thyroid surgical dissection device of the present invention: the dissection head includes a base connected to a hinge joint, and an arc-shaped rod disposed at the extension of the base.

[0014] In a preferred embodiment of the thyroid surgical dissection device of the present invention: the crank is fixedly snapped onto the base; The sleeve includes a clearance groove extending along the sleeve axis, the clearance groove being used to accommodate the swing of the arcuate rod.

[0015] The beneficial effects of this invention are as follows: A rotating turntable drives the adjusting rod and piston rod to move axially, and through the connecting rod transmission of the rotating assembly, the linear motion is ultimately converted into precise deflection of the dissecting head around its hinge point with the hinge joint. This allows the surgeon to adjust the working angle of the dissecting head in real time according to anatomical needs using only their thumb, achieving stepless angle adjustment during surgery and avoiding tissue damage caused by improper angle. Furthermore, when the dissecting head contacts or compresses tissue, resistance is fed back to the piston chamber, causing changes in pressure within the chamber. The surgeon can perceive the increased resistance through the turntable. This keeps the pressure acting on the tissue within a safe threshold, effectively preventing rigid crush injuries.

[0018] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0019] Reference Figures 1-6This embodiment provides a thyroid surgical removal device, including a handle 1 including an operating handle 11, a mounting cavity 12 opened inside the operating handle 11, and a connecting tube 13 connected to one side of the operating handle 11. The peeling part 2 is located on one side of the handle 1 and includes a connecting component 21 sleeved on the outside of the connecting tube 13, a peeling head 22 sleeved on the upper end of the inner periphery of the connecting component 21, an auxiliary head 23 fixed on the lower end of the inner periphery of the connecting component 21, and a rotating component 24 hinged to one side of the peeling head 22. The adjustment unit 3 is located inside the mounting cavity 12. It includes a turntable 31 disposed in the mounting cavity 12, an adjustment rod 32 connected to the inner side of the turntable 31, a piston rod 33 sleeved on the inner side of the adjustment rod 32, and a transmission sleeve 34 sleeved on the outer wall of the piston rod 33. The piston rod 33 is connected to the rotating assembly 24 via the transmission sleeve 34.

[0020] Furthermore, the connecting assembly 21 includes a sleeve 211 fixedly sleeved around the outer periphery of the connecting tube 13, a snap ring 212 protruding from one end of the sleeve 211, and a hinge joint 213 sleeved around the snap ring 212. The hinge joint 213 is hinged to the stripping head 22 and the auxiliary head 23 at its two ends, respectively.

[0021] Furthermore, the handle 1 also includes a floral sleeve 14 that is fitted onto the outside of the connecting tube 13.

[0022] In this embodiment, the handle 1 serves as the main operating body, providing the operator with a base for gripping and housing the adjustment mechanism. The dissection part 2, located at the front end of the handle, is an instrument used to dissect thyroid tissue. The adjustment unit 3 is integrated inside the handle 1, enabling stepless adjustment of the working angle of the dissection part 2 through mechanical transmission.

[0023] Preferably, the operating handle 11 has an elliptical cross-section with finger grooves to fit the hand; the operating handle 11 is a mating structure, fastened by screws, and the space formed inside the mating structure forms a mounting cavity 12. The mounting cavity 12 is a cylindrical cavity opened inside the operating handle 11 along its long axis; the mounting cavity 12 is used to accommodate and fix the adjustment unit 3.

[0024] The connecting tube 13 is a hollow tubular structure, one end of which is fixedly connected to the front end of the operating handle 11 and extends to the distal end. Its function is to support and penetrate the peeling part 2. The sleeve 14 is an annular component that is fitted onto the outside of the connecting tube 13. Its inner wall has internal threads; the connecting tube 13 can be threadedly fixed to the front end of the operating handle 11.

[0025] Preferably, the peeling part 2 is embedded inside the connecting tube 13 at the front end of the handle 1. The connecting assembly 21 is used to connect the peeling part 2 and the adjusting unit 3. The sleeve 211 is fixedly mounted on the outer circumference of the distal end of the connecting tube 13, achieving initial fixation between the peeling part 2 and the handle 1. The snap-fit ​​ring 212 is an annular flange protruding radially outward from the end face of the sleeve 211. The circular groove inside the snap-fit ​​ring 212 is used for fixed engagement with the hinge joint 213 to ensure a stable and detachable connection.

[0026] The hinge joint 213 is a double-headed hinge joint, which is fixedly connected by being embedded in the circular groove of the snap ring 212 on its periphery; both ends of the hinge joint 213 are through, one end is hinged to the stripping head 22, and the other end is hinged to the auxiliary head 23, so as to realize the double-head linkage.

[0027] Preferably, the stripping head 22 is hinged to the upper end of the hinge joint 213 via a pin; the auxiliary head 23 is hinged to the lower end of the hinge joint 213 via a pin.

[0028] Preferably, the working end of the dissecting head 22 is designed in a blunt, rounded shovel or spoon shape with smooth edges and no sharp corners, for blunt separation and pushing of the thyroid gland from surrounding tissues. The auxiliary head 23 may have a different shape from the dissecting head 22, and its working end may be designed in a blunt hook or flat blunt head shape, for hooking or pressing small blood vessels and fibrous strands during the separation process to facilitate the operation of the dissecting head 22, or to protect the underlying nerves.

[0029] Preferably, the auxiliary head is a hollow tubular structure with an internal negative pressure suction channel, connected to an external negative pressure suction device via a connecting tube. When bleeding occurs during the dissection procedure, the surgeon can activate the negative pressure suction and use the auxiliary head to remove the accumulated blood, maintaining a clear surgical field.

[0030] Preferably, the rotating assembly 24 is a linkage mechanism, with one end hinged to the non-working surface of the stripping head 22, and the other end extending rearward, passing through the hollow portion of the hinge joint 213 and the sleeve 211, and finally connected to the adjustment unit 3 for transmission. The outer edge of the turntable 31 is exposed on the outer surface of the operating handle 11, facilitating the operator's thumb or forefinger to perform a rotary operation.

[0031] One end of the adjusting rod 32 is connected to the inner axis of the turntable 31 and rotates in a circular motion as the turntable 31 rotates. The piston rod 33 is a rod-shaped component that reciprocates along its axis. The transmission sleeve 34 is sleeved on the outer wall of the piston rod 33 and can slide along it. The other end of the transmission sleeve 34 is connected to the rotating assembly 24, ensuring that the piston rod 33 is connected to the rotating assembly 24 through the transmission sleeve 34.

[0032] If the doctor wants to change the angle of the dissecting head 22, they only need to press the turntable 31 firmly with their thumb. The turntable 31 then rotates the adjusting rod 32, and the piston rod 33 moves back and forth due to the internal threads. Next, the piston rod 33 can push or pull the transmission sleeve 34, causing the rotating component 24 to swing. This allows the dissecting head 22 to rotate along the point where it connects to the hinge joint 213, achieving a certain angle of vertical rotation. In this way, the doctor can perform the surgical procedure without twisting their hand, instead using their thumb to rotate the dissecting head 22 to the safest position to touch the tissue, preventing the vein wall from being punctured due to the instrument being in a vertical position.

[0033] In summary, due to the function of the rotating turntable 31, the angle of the end of the dissection head 22 can be finely adjusted in real time during the operation. Therefore, when the wall of the middle vein on the side of the thyroid gland is thin, the dissection head 22 can be adjusted to a sliding angle that is inclined to the direction of the blood vessel before dissection. In this way, the tissue can be pushed away from the side without directly hitting the blood vessel, which fundamentally avoids the blood vessel wall being punctured or torn due to the vertical angle.

[0034] Reference Figures 3-4 As an optional embodiment, in one embodiment provided by the present invention, the adjusting rod 32 includes a driving section 321 connected to the turntable 31, and a connecting section 322 protruding from the end of the driving section 321; The connecting section 322 is fixedly engaged with the piston rod 33.

[0035] Furthermore, the drive section 321 includes straight slots 3211 formed on both sides thereon; A transmission pin 3212 is slidably connected inside the straight groove 3211.

[0036] Furthermore, the transmission sleeve 34 includes a piston chamber 341 formed therein; The piston chamber 341 is sealed to the outer wall of the piston rod 33 to form a negative pressure drive space.

[0037] Furthermore, the rotating assembly 24 includes a push rod 241 slidably connected in the piston chamber 341, a connecting rod 242 hinged to the end of the push rod 241, and a crank 243 hinged to the other side of the connecting rod 242.

[0038] In this embodiment, see Figure 3 One end of the adjusting rod 32 is a drive section 321, which is a stud so as to be threadedly connected to the turntable 31 and axially moved by rotation; the other end is a connecting section 322, which protrudes from the end of the drive section 321 and is fixedly connected to the piston rod 33 by a snap-fit ​​structure.

[0039] Two axial rectangular straight grooves 3211 are symmetrically milled on both sides of the cylinder near the front end of the drive section 321. These two straight grooves 3211 are not for through-hole pins, but serve as guide and limiting grooves. A transmission pin 3212 is slidably connected within the straight grooves 3211. The transmission pin 3212 passes through the side wall of the operating handle 11, thereby limiting the axial displacement of the transmission pin 3212. When the turntable 31 rotates, the drive section 321 moves axially under the action of the thread.

[0040] For a better option, see [link / reference]. Figure 4 Inside the cylinder of the transmission sleeve 34, a through cylindrical piston cavity 341 is machined. The front end of the piston rod 33 is inserted into one end of this piston cavity 341, while the push rod 241 forms a sliding seal with the other end of the piston cavity 341 to ensure that the cavity maintains a negative pressure environment.

[0041] Preferably, at least one O-ring is provided at the inlet of the piston chamber 341, which forms a dynamic seal with the outer wall of the piston rod 33. Similarly, at least one O-ring is provided between the push rod 241 and the piston chamber 341, forming a closed negative pressure drive space 343.

[0042] When the turntable 31 rotates, the drive section 321, through a threaded connection, drives the adjusting rod 32 to move axially, while the connecting section 322 at the end of the drive section 321 drives the piston rod 33 to move axially synchronously. The piston rod 33 moves synchronously within the piston chamber 341, and the push rod 241 is displaced axially by the internal negative pressure.

[0043] Ideally, the traditional rigid thyroid dissector structure completely transmits the surgeon's manual manipulation to its end. If exposing delicate nerves or blood vessels, the end will touch the sensitive areas, but because the rigid metal is extremely stiff, even very small changes in force can cancel out this information. Therefore, the surgeon's fingers are completely unaware that the end is approaching dangerous tissue, and by the time they feel the end pressing against the tissue, it is often already under pressure or even traction. Furthermore, the surgeon's physiological hand tremors are directly transmitted through the rigid rod. More seriously, during rapid or fine adjustments, the instrument's inertia can cause overshoot—that is, the dissector head goes beyond its intended position and hits non-target tissue.

[0044] The piston chamber 341 utilizes a closed-loop pneumatic flexible transmission principle. When the doctor rotates the turntable 31, the piston rod 33 attempts to compress the piston chamber 341. The resistance generated by the compression at the end of the piston chamber 341 is flexibly transmitted to the push rod 241, and finally fed back to the dissecting head 22 via the connecting rod 242. This process achieves buffering and smooth force transmission, allowing for more gentle and delicate manual adjustment by the doctor. Furthermore, when the dissecting head 22 approaches a nerve or blood vessel, a slight change in air pressure occurs within the chamber. This slight change in air pressure is reflected back to the handle via the push rod 241, providing a tactile effect and preventing excessive force that could damage the patient's nerves or blood vessels. Simultaneously, the compressibility of the gas effectively counteracts accidental hand movements caused by hand tremors and operational inertia, reducing overshoot. By eliminating the impact and rigid reaction during the operation, the dissection of the head 22 becomes more stable, gentle, and controllable. There is virtually no damage to the delicate nerves and blood vessels caused by unstable operation, which effectively improves the safety and precision of the operation.

[0045] The clearance groove 2111 provided on the sleeve 211 is a long strip-shaped window that runs through its axis. During the process of the arc rod 222 swinging at an angle under the drive of the crank rod 243, its rod body will not mechanically interfere with the sleeve 211.

[0046] Reference Figures 1-6 As an optional embodiment, in one embodiment provided by the present invention, the rotating assembly 24 includes a push rod 241 slidably connected in the piston chamber 341, a connecting rod 242 hinged to the end of the push rod 241, and a crank 243 hinged to the other side of the connecting rod 242.

[0047] Furthermore, the mounting cavity 12 includes a guide groove 121 formed on its inner wall, a receiving groove 122 for embedding the turntable 31, and mounting holes 123 provided on both sides of the receiving groove 122.

[0048] Furthermore, the stripping head 22 includes a base 221 connected to the hinge joint 213, and an arcuate rod 222 provided at the extension of the base 221.

[0049] Furthermore, the crank 243 is fixedly attached to the base 221; The sleeve 211 includes a clearance groove 2111 extending along the sleeve axis, the clearance groove 2111 being used to accommodate the swing of the arc-shaped rod 222.

[0050] In this embodiment, one end of the push rod 241 is slidably connected to the inside of the piston chamber 341 via a sealed bearing, allowing it to slide freely axially within the chamber while maintaining a sealed cavity; the other end is hinged to one end of the connecting rod 242 via a pin. The connecting rod 242 is a flexible connecting rod, and its tail end is connected to the end of the crank rod 243 via a pin.

[0051] Preferably, the crank 243 is an L-shaped rod, and its turning point is connected to the base 221 via a pin to form a rotation fulcrum. The guide groove 121 is an axial straight groove formed in the inner wall of the mounting cavity 12, which cooperates with the guide key on the outer wall of the piston rod 33 to effectively restrict the rotational freedom of the piston rod 33, ensuring that it can only perform axial linear motion, and purely converting the rotation of the turntable 31 into pushing and pulling. The receiving groove 122 is a radially recessed annular groove whose size matches that of the turntable 31, used to embed and position the turntable 31, ensuring that the turntable 31 does not wobble when rotating, while part of its rim is exposed outside the operating handle 11 for easy operation. The mounting holes 123 are symmetrically formed on both sides of the receiving groove 122 for installing and fixing the transmission pin 3212.

[0052] Preferably, the base 221 of the dissecting head 22 has a locking interface that matches the end of the crank 243, ensuring effective torque transmission. The arc-shaped bar 222 extends forward from the base 221, and its arc shape not only conforms better to the tissue surface during dissection, but also optimizes its swing trajectory.

[0053] The clearance groove 2111 on the sleeve 211 is an elongated window extending along its axial direction. When the arc rod 222 swings at an angle under the drive of the crank 243, its body will not mechanically interfere with the sleeve 211.

[0054] When the piston rod 33 is driven by the turntable 31 to move forward or backward, the push rod 241 slides within the piston chamber 341, pushing or pulling the crank 243 via the connecting rod 242. Then, the crank 243 rotates around its hinge point with the hinge joint 213, thereby driving the stripping head 22 fixed thereto to deflect at an angle around the same straight line.

[0055] In summary, this invention drives the adjusting rod 32 and piston rod 33 to move axially via a rotating turntable 31, and then transmits this linear motion through the linkage of the rotating assembly 24, ultimately converting the linear motion into precise deflection of the dissecting head 22 around its hinge point with the hinge joint 213. This allows the surgeon to adjust the working angle of the dissecting head in real time according to anatomical needs using only their thumb, achieving stepless angle adjustment during surgery and avoiding tissue damage caused by improper angle. Furthermore, when the dissecting head 22 contacts or compresses tissue, resistance is fed back to the piston chamber, causing a change in pressure within the chamber. The surgeon can perceive this increased resistance through the turntable 31. This keeps the pressure acting on the tissue within a safe threshold, effectively preventing rigid crush injuries.

[0056] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
