Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a thyroid surgery traction device. Background Technology

[0002] During thyroid surgery, an incision is made in the lower part of the patient's neck, corresponding to the location of the thyroid gland, through which surgical procedures such as thyroidectomy are performed. To prevent the incision from closing, a traction device is used to keep the incision open so that the thyroid gland and surrounding tissues are exposed.

[0003] The currently used traction device is a thyroid retractor, which is a thin, sheet-like instrument made of metal with one end bent into a hook shape. During surgery, the tail of the thyroid retractor is held, and the hook-shaped part is used to hook the surgical incision and pull it outward. Numerous patents, including application numbers 202020575128.1, 202111443485.8, and 201420329446.4, disclose thyroid surgical retractors.

[0004] During thyroid surgery, at least two retractors are generally required to open the incision in two directions; sometimes four retractors are needed to open the incision in four directions. When using one or two retractors, one person is needed to perform the traction; when using four retractors, two people are needed to perform the traction. This not only requires more personnel for the surgery but also makes the area around the patient quite crowded. Thyroid surgery generally takes more than an hour, and the labor intensity for those performing the traction is also quite high. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a thyroid surgery traction device that can open the surgical incision without long-term manual intervention.

[0006] The technical solution adopted to solve the above problems is: a thyroid surgery traction device with a traction puller and a traction puller fixing device; the traction puller includes a ring guide rail, a traction structure, and a pull hook; the number of traction structures is at least two, the traction structures are fitted on the ring guide rail and can move along the ring guide rail, the traction structure includes a traction rod that can move radially inward and outward along the ring guide rail; the pull hook is set one-to-one with the traction structure and is detachably connected to the traction rod; the number of traction puller fixing devices is two, the two traction puller fixing devices are respectively set on both sides of the traction puller and connected to the ring guide rail, and the outer end of the traction puller fixing device can be detachably connected to the operating table.

[0007] Furthermore, the traction structure includes a sliding sleeve, a traction sleeve, a traction sleeve end plate, and a traction cover. The sliding sleeve is fitted onto and mates with the annular guide rail. The traction sleeve is radially arranged along the annular guide rail and connected to the sliding sleeve. The traction sleeve end plate is connected to the inner end of the traction sleeve, and the center of the traction sleeve end plate has a guide hole. The traction cover is fitted onto the outer end of the traction sleeve and can rotate. The traction sleeve restricts the inward and outward movement of the traction cover. The center of the traction cover has a threaded hole. The traction rod includes a hook, a smooth rod section, and a screw section arranged sequentially from the inside out. The smooth rod section passes through and mates with the guide hole, which restricts the rotation of the smooth rod section. The screw section is connected to the threaded hole. Rotation of the traction cover can drive the traction rod to move inward and outward. The outer end of the hook is hooked onto the hook.

[0008] Furthermore, the number of tension structures is four.

[0009] Furthermore, the traction device includes a connecting rod and a bed edge clamp, with both ends of the connecting rod connected to the bed edge clamp and the annular guide rail, respectively.

[0010] Furthermore, the connecting rod is telescopic.

[0011] Furthermore, the bed edge clamp includes a U-shaped clamp body and a tightening screw, which is connected to either side plate of the U-shaped clamp body.

[0012] Furthermore, the traction device includes a vertical rod, and the connecting rod is connected to the edge clamp of the bed through the vertical rod.

[0013] Furthermore, the pole is retractable.

[0014] The beneficial effects of this utility model are as follows: The process of using this utility model to assist in thyroid surgery is as follows: After making an incision in the neck corresponding to the thyroid gland, this utility model is set up. Specifically, the outer end of the traction device is connected to the operating table to fix the utility model; the center of the annular guide rail is roughly aligned with the center of the surgical incision; one end of the hook is hooked onto the surrounding tissue of the surgical incision, and the other end is connected to the traction rod; then the position of the traction rod is adjusted, and the traction rod drives the hook to move outward, thus opening the surgical incision. Once this utility model is set up, the surgery can begin. During the surgery, if it is necessary to adjust the traction position, the position of the traction rod is adjusted to move the hook inward and remove the hook, then the traction structure is moved along the annular guide rail, and after adjusting the position, the hook is set up again for traction.

[0015] It is evident that this invention can effectively open surgical incisions. Adjustments are only required during device setup and during the surgical procedure; otherwise, the pulling of the surgical incision requires no manual intervention. Furthermore, the setup and adjustment of this invention can be completed by a single person. Using this invention to assist in thyroid surgery reduces the number of surgical assistants, lowers labor intensity, and avoids crowding around the patient during surgery, thus facilitating the procedure.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 4 As shown, the thyroid surgery traction device includes a traction device 1 and a traction device fixing device 2. The traction device 1 includes an annular guide rail 11, a traction structure 12, and a hook 13. There are at least two traction structures 12, which are mounted on the annular guide rail 11 and can move along the annular guide rail 11. Each traction structure 12 includes a traction rod 124 that can move radially inward and outward along the annular guide rail 11. The hooks 13 are arranged one-to-one with the traction structures 12 and are detachably connected to the traction rods 124. There are two traction device fixing devices 2, which are respectively arranged on both sides of the traction device 1 and connected to the annular guide rail 11. The outer ends of the traction device fixing devices 2 can be detachably connected to the operating table 3.

[0023] The process of using this utility model to assist in thyroid surgery is as follows: After making an incision in the neck corresponding to the thyroid gland, the utility model is set up. Specifically, the outer end of the traction fixation device 2 is connected to the operating table 3 to fix the utility model; the center of the annular guide rail 11 is roughly aligned with the center of the surgical incision; one end of the hook 13 is hooked onto the human tissue around the surgical incision, and the other end is connected to the traction rod 124; then the position of the traction rod 124 is adjusted, and the traction rod 124 drives the hook 13 to move outward, thus opening the surgical incision. With the utility model set up, surgery can begin. During surgery, if it is necessary to adjust the traction position, the position of the traction rod 124 is adjusted, the hook 13 is moved inward and removed, and then the traction structure 12 is moved along the annular guide rail 11. After adjusting the position, the hook 13 is set up again for traction.

[0024] It is evident that this invention can effectively open surgical incisions. Adjustments are only required during device setup and during the surgical procedure; otherwise, the pulling of the surgical incision requires no manual intervention. Furthermore, the setup and adjustment of this invention can be completed by a single person. Using this invention to assist in thyroid surgery reduces the number of surgical assistants, lowers labor intensity, and avoids crowding around the patient during surgery, thus facilitating the procedure.

[0025] The traction structure 12 can have various specific structures. The preferred structure of this utility model is as follows: The traction structure 12 includes a sliding sleeve 125, a traction sleeve 121, a traction sleeve end plate 122, and a traction cover 123. The sliding sleeve 125 is fitted onto and cooperates with the annular guide rail 11. The traction sleeve 121 is radially arranged along the annular guide rail 11 and connected to the sliding sleeve 125. The traction sleeve end plate 122 is connected to the inner end of the traction sleeve 121. The center of the traction sleeve end plate 122 has a guide hole 1221. The traction cover 123 is fitted onto the outer end of the traction sleeve 121. The traction cover 123 can... The pull sleeve 121 restricts the inward and outward movement of the pull cover 123. The pull cover 123 has a threaded hole 1231 at its center. The pull rod 124 includes a hook 1243, a smooth rod section 1242, and a screw section 1241 arranged sequentially from the inside to the outside. The smooth rod section 1242 passes through the guide hole 1221 and engages with the guide hole 1221. The guide hole 1221 restricts the rotation of the smooth rod section 1242. The screw section 1241 is connected to the threaded hole 1231. The rotation of the pull cover 123 can drive the pull rod 124 to move inward and outward. The outer end of the hook 13 is hung on the hook 1243.

[0026] The traction structure 12 is actually a lead screw and nut mechanism. Rotating the traction cover 123 restricts its inward and outward movement, and the guide hole 1221 restricts the rotation of the smooth rod section 1242. This rotation of the traction cover 123 causes the traction rod 124 to translate inward and outward. Specifically, the guide hole 1221 and the smooth rod section 1242 can both be square in shape. The rear end of the traction sleeve 121 has a flange. The traction sleeve 121 restricts the inward and outward movement of the traction cover 123 in the following way: Figure 3 As shown, the traction sleeve 121 has a flange and is divided into two parts, located on the inner and outer sides of the flange respectively. The two parts are connected and cover the flange, thus restricting the inward and outward movement of the traction cover 123. The annular guide rail 11 can be made of stainless steel, and the sliding sleeve 125 can be made of plastic. The sliding sleeve 125 and the annular guide rail 11 have a small interference fit, so that the sliding sleeve 125 will not easily slide on the annular guide rail 11, and the sliding sleeve 125 can be moved with a small force. The inner end of the hook 13 is hook-shaped, and the specific shape is based on the existing thyroid surgery hook design. The outer end of the hook 13 has a hanging hole, through which the outer end of the hook 13 is hung on the hook 1243.

[0027] During thyroid surgery, two to four retractors 13 are commonly used. Therefore, this invention preferably uses four traction structures 12. When four retractors 13 are used, each of the four retractors 13 is connected to one of the four traction structures 12. When two or three retractors 13 are used, some of the traction structures 12 are selected to connect to the retractors 13.

[0028] The specific structure of the tensioner fixing device 2 is as follows: Figure 4 As shown, the traction device 2 includes a connecting rod 22 and a bed edge clamp 21. The two ends of the connecting rod 22 are connected to the bed edge clamp 21 and the annular guide rail 11, respectively.

[0029] The edge clamp 21 is clamped onto the edge of the operating table 3, thus fixing the device to the operating table 3 and preventing the puller 1 from shifting during traction. Specifically, the edge clamp 21 includes a U-shaped clamp body 211 and a tightening screw 212, with the tightening screw 212 connected to either side plate 2111 of the U-shaped clamp body 211. The clamp body 211 is secured to the edge of the operating table 3, and the tightening screw 212 is then tightened to secure the operating table 3, thus securing the edge clamp 21.

[0030] Preferably, the connecting rod 22 is telescopic. This has two advantages: first, when the connecting rod 22 is extended, the bed edge clamp 21 can be positioned outside the operating table 13; when the connecting rod 22 is shortened, the bed edge clamp 21 can be clamped onto the edge of the bed. Second, the telescopic nature of the connecting rod 22 can adjust the left-right position of the traction device 1 for alignment with the surgical incision. Moving the bed edge clamp 21 back and forth can adjust the front-back position of the traction device 1, also facilitating alignment with the surgical incision.

[0031] Obviously, the traction device 1 should have a certain height and needs to be positioned above the patient's neck. Therefore, it can be configured as follows: the traction device fixing device 2 includes a vertical rod 23, and a connecting rod 22 is connected to the bed edge clamp 21 through the vertical rod 23. The vertical rod 23 is used to elevate the traction device 1.

[0032] Preferably, the upright post 23 is telescopic. This allows the height of the traction device 1 to be adjusted, thereby adjusting the distance between the traction device 1 and the patient's neck.

[0033] Both the connecting rod 22 and the upright rod 23 are telescopic rods, and their specific structures can adopt the structures of existing common telescopic rods. It should be noted that the connecting rod 22 and the upright rod 23 should be able to lock in length after the telescopic adjustment to prevent movement after the position of the puller 1 is adjusted.
