Specifically in the treatment of thyroid diseases, in laparoscopic thyroid surgery, separation and exposure of the thyroid gland is the key operation of the operation. Successful dissection and exposure of the thyroid gland can ensure a clear field of view during the operation, avoid intraoperative bleeding and damage to important nerves. When performing gland dissection operations in thyroid surgery, a thyroid dissector is required.

[0003] The thyroid stripper in the prior art usually includes a handle, a stripping head, and a stripping rod with a handle and a stripping head respectively installed at both ends. During operation, the stripping head at the front end of the stripping rod is extended to the position of the thyroid gland by holding the handle, and then the stripping operation is performed with the help of the stripping head. Then, when the current thyroid stripper is used, first of all, its handle is usually a sleeve straight handle style, which causes the handle to be easily rotated and misaligned with the palm during the holding operation, which will directly cause the position of the stripping head to change and affect the stripping operation of the thyroid gland. At the same time, after the stripping head is fixed at the front end of the stripping rod, since the length of the stripping rod is constant, the extended position of the stripping head cannot be properly adjusted according to actual conditions.

[0032] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-6As shown, the present invention provides a thyroid stripper, including a stripping rod body 2 and a stripping head 1. The stripping rod body 2 is provided with three sections, namely a head rod 201 at the rear, a connecting rod 202 in the middle and a tail rod 203 at the front, and the head rod 201 and the tail rod 203 are connected as a whole through the connecting rod 202. The front part of the head rod 201 is detachably mounted with a stripping head 1 capable of axial sliding adjustment of the extended position through a combined connecting piece 4. Specifically, the combined connecting piece 4 includes a matching rod 402 and a matching groove 403. The connecting end plate 101 at the rear end of the stripping head 1 is fixed with the matching rod 402 along the axial direction of the head rod 201. The front end of the head rod 201 is provided with a matching groove 403 along the axial direction, and the matching rod 402 is inserted into the matching groove 403 in a coaxial sliding manner. The outer periphery of the head rod 201 is provided with a mounting hole 401 radially near the front end. The stripping head 1 can be removed from the front of the head rod 201 by loosening the clamping stud 405 and sliding the clamping stud 405 from the front end of the mating groove 403. The stripping head 1 can be reassembled and installed on the front of the head rod 201 by simply sliding the rear end of the mating rod 402 from the front end of the mating groove 403. The disassembly and assembly of the stripping head 1 at the front of the head rod 201 is simple and easy to achieve.

[0034] See also Figure 1-Figure 4As shown, the outside of the tail rod 203 is coaxially and detachably installed with a hand grip 3 that can avoid rotational misalignment with the palm during gripping. Specifically, the hand grip 3 includes a grip sleeve 302 and a wing plate 303. The grip sleeve 302 is coaxially and detachably fixed to the periphery of the tail rod 203. The wing plate 303 is fixed to the lower portion of the periphery of the grip sleeve 302 extending vertically downward along the axial direction of the tail rod 203, and the wing plate 303 is provided with a plurality of finger insertion holes 304 for the medical staff to pass through in sequence with the four fingers other than the thumb. The purpose of this arrangement is that the medical staff first grasps the grip sleeve with their hand 302 and by passing the fingers through the finger insertion holes 304 in turn and then holding it tightly, the holding sleeve 302 and the palm can be prevented from being rotated and misaligned. At the same time, the inner periphery of the holding sleeve 302 is coaxially threaded with the tail rod 203 and the top of the holding sleeve 302 is pressed against the limiting ring 301, so the holding sleeve 302 and the wing plate 303 can be detachably combined with the tail rod 203. In addition, the holding sleeve 302 and the tail rod 203 can be separated from each other by simply twisting the holding sleeve 302 in the opposite direction. The combination and disassembly of the holding sleeve 302, the wing plate 303 and the tail rod 203 are simple and easy to achieve.

[0035] See also Figure 1-Figure 4 As shown, the peeling rod body 2, the combined connector 4, and the hand grip 3 have been optimized as follows. Specifically, in the peeling rod body 2, the head rod 201 and the tail rod 203 form a certain angle, and the connecting rod 202 smoothly transitions between the head rod 201 and the tail rod 203, so that the peeling rod body 2 has a design that meets operational requirements. Specifically, in the combined connector 4, the cross-section of the mating rod 402 and the mating groove 403 are both rectangular, providing good positioning and guidance when the mating rod 402 slides axially along the mating groove 403. Optionally, the inner end of the compression stud 405 is coaxially fixed with an elastic pressure piece 406 having an outer diameter smaller than the diameter of the mounting hole 401, and the outer end of the compression stud 405 is coaxially provided with an external hexagonal force application groove 404. This arrangement facilitates the stability of the compression of the mating rod 402 by pressing the elastic pressure piece 406 against the surface of the mating rod 402, and avoids damaging the surface of the mating rod 402. At the same time, the arrangement of the force application groove 404 allows the compression stud 405 to be tightened with the help of an external hexagonal wrench or other tool. Further, the mating groove 403 is a blind groove in the axial direction of the head rod 201, and the axial length of the mating rod 402 is not less than the axial length of the mating groove 403, and the groove length of the mating groove 403 is not less than one-third of the length of the head rod 201. This arrangement facilitates the mating groove 403 to have a relatively wide adjustment length in the axial direction, ensuring that the stripping head 1 can be adjusted to a variety of different extended positions.

[0036] Specifically, regarding the hand grip 3, the inner periphery of the grip sleeve 302 is provided with an internal thread, and the outer periphery of the tail rod 203 is provided with an external thread. The inner periphery of the grip sleeve 302 and the outer periphery of the tail rod 203 are coaxially and detachably connected by threaded engagement, so that the grip sleeve 302 and the tail rod 203 can be quickly assembled and disassembled by twisting the grip sleeve 302. Optionally, the surface of the grip sleeve 302 is provided with alternating concave and convex anti-slip grooves 305, and there are four finger insertion holes 304. This arrangement not only facilitates good anti-slip effect when gripping the grip sleeve 302, but also facilitates smooth insertion of the other four fingers of the gripping hand, excluding the thumb, through the finger insertion holes 304. Further optionally, a limiting ring 301 is coaxially fixed to the upper part of the tail rod 203, and the limiting ring 301 is a rubber ring. When the wing plate 303 is in a state of extending vertically downward along the axial direction of the tail rod 203, the top end surface of the holding sleeve 302 is in close contact with the bottom end surface of the limiting ring 301. Such a setting is convenient for clearly indicating that the combination of the holding sleeve 302 and the wing plate 303 with the tail rod 203 is in place by the top end surface of the holding sleeve 302 being in close contact with the bottom end surface of the limiting ring 301, and at the same time, it can also have a certain anti-loosening effect on the combined state of the holding sleeve 302 on the periphery of the tail rod 203.

[0037] The above structure is adopted, specifically in the thyroid gland peeling operation, because the hand grip 3 is coaxially installed on the tail rod 203 of the peeling rod body 2, and the lower part of the grip sleeve 302 of the hand grip 3 is fixed with a wing plate 303 extending downward, and the wing plate 303 is provided with a plurality of finger insertion holes 304 for the fingers of the gripping hand to pass through respectively, so that the medical staff can grasp the grip sleeve 302 with their hands and pass the four fingers other than the thumb through the finger insertion holes 304 in turn and then hold it tightly, thereby avoiding the rotational misalignment between the grip sleeve 302 and the palm, and avoiding the peeling operation. The treadmill 302 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill 303 is then pulled out of the reach of the user, and the treadmill The assembly and disassembly of the barrel 302 and the wing plate 303 with the tail rod 203 is simple and easy to implement, which is convenient for cleaning and maintenance after the holding sleeve 302 and the wing plate 303 are removed. Specifically for the stripping head 1, since the connecting end plate 101 at the rear of the stripping head 1 is installed in the front of the head rod 201 of the stripping rod body 2 through the combined connecting piece 4, the outward extension position of the stripping head 1 can be adjusted by sliding the mating rod 402 axially along the mating groove 403 and tightening the clamping stud 405 to press the elastic pressing piece 406 on the surface of the mating rod 402, which is convenient for adjusting the outward extension of the stripping head 1 according to actual conditions. The extension position can be properly adjusted to improve the applicability of the stripping head 1 when in use. After loosening the compression stud 405, the stripping head 1 can be detached from the front of the head rod 201 by sliding the matching rod 402 from the front end along the matching groove 403. At the same time, the stripping head 1 can be reassembled and installed on the front of the head rod 201 by simply sliding the rear end of the matching rod 402 from the front end of the matching groove 403. The disassembly and assembly of the stripping head 1 at the front of the head rod 201 is simple and easy to implement, which is convenient for combining the stripping head 1 at the front of the head rod 201 for use and convenient for subsequent maintenance and replacement of the stripping head 1.
