Description

Technical Field

[0001] The utility model discloses an internal expander for thyroid surgery, belonging to the technical field of medical surgical expander devices, and in particular to the technical field of internal expanders for thyroid surgery. Background Art

[0002] After the thyroid gland becomes diseased, it is sometimes necessary to undergo surgery for treatment. During the surgical treatment, an incision is made in the human neck, and then the thyroid gland is surgically removed. In order to facilitate observation of the thyroid gland during removal, a expander is needed to expand the opening. Currently, there are many expansion structures on the market, but in actual surgical procedures, it is inconvenient to fix the position of the expander, which may cause the expander to move during the operation. Furthermore, sometimes the size of the expansion needs to be changed in the middle of the operation. Current expanders are inconvenient to adjust. In order to solve the above problems, we propose a built-in expander for thyroid surgery. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a built-in expander for thyroid surgery, thereby solving the problem of the inconvenience of fixing the position of the expander, which may cause the expander to be displaced during the operation. Moreover, sometimes the size of the expander needs to be changed in the middle of the operation, and the current expander has the problem of inconvenient adjustment.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A built-in expander for thyroid surgery comprises a positioning base placed at the back of the neck when in use, with pull-out connectors detachably connected to both sides of the positioning base, and connecting hooks for expanding the surgical incision are installed at the ends of the pull-out connectors.

[0006] As a preferred technical solution of the utility model, the positioning base includes an annular lining, and the outer ring of the annular lining is connected to adjustment belts on both sides by magic tape, and the inner ring surface of the annular lining is adhered with adhesive tape, and the adjustment belt is distributed with connecting holes.

[0007] As a preferred technical solution of the utility model, the pull-open connecting piece includes an arc-shaped piece, a protrusion is installed at the position of the arc-shaped piece corresponding to the connecting hole, and an adsorption cotton is sleeved on the outside of the arc-shaped piece between the protrusion and the connecting hook.

[0008] As a preferred technical solution of the utility model, an auxiliary opening rope for assisting in adjusting the size of the opening is installed on the arc-shaped piece between the protrusion and the adsorption cotton.

[0009] As a preferred technical solution of the utility model, a draw hook is provided at the hooking position of the connecting hook, the draw hook is arranged in an M shape, and a fixing ring placed inside the arc-shaped piece is installed at the bottom end of the draw hook.

[0010] Compared with the prior art, the beneficial effect of the utility model is that during use, the whole body is fixed at the bottom end of the neck by the positioning base, so that the whole body can move with the movement of the neck. Therefore, even if the patient's neck moves during the operation, it will not affect the expansion effect. At the same time, the whole body is not easy to move, thereby ensuring the stability of the expansion. Moreover, when re-expansion operation is required in the middle of the operation, the auxiliary expansion rope can be pulled outward, and then the end of the auxiliary expansion rope can be hung on the protrusion, thereby performing another expansion operation, and the operation is simple and quick.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 , the utility model provides a technical solution:

[0017] A built-in expander for thyroid surgery comprises a positioning base 1 which is placed at the back of the neck when in use, with pull-out connectors 2 detachably connected to both sides of the positioning base 1, and connecting hooks 4 for expanding the surgical incision installed at the ends of the pull-out connectors 2. Since most patients adopt a supine position during thyroid surgery, the back of the neck is mostly pressed against the operating table. Therefore, the positioning base 1 is placed at the back of the neck to be compressed by the patient's own weight to avoid movement, and it is adhered to the back of the neck by an adhesive tape 6, so that even if the neck rotates, the expansion effect will not be affected, and the position of the pull-out connector 2 on the positioning base 1 is adjusted to change the distance between the two connecting hooks 4, thereby realizing the expansion operation of incisions of different sizes.

[0018] The positioning base 1 includes an annular lining 5, and adjusting belts 7 are connected to the outer ring of the annular lining 5 on both sides by magic tape, and an adhesive tape 6 is adhered to the inner ring surface of the annular lining 5. Connecting holes 8 are distributed on the adjusting belt 7. Therefore, by adjusting the position of the adjusting belt 7 on the annular lining 5, the overall length of the positioning base 1 can be adjusted according to the use requirements, thereby meeting different use requirements.

[0019] The pull-open connector 2 includes an arc-shaped piece 9, on which a protrusion 10 is installed at a position corresponding to the connecting hole 8, and an adsorption cotton 11 is sleeved on the outside of the arc-shaped piece 9 between the protrusion 10 and the connecting hook 4, and the protrusion 10 is arranged to be an inverted convex shape, so that the arc-shaped piece 9 can be more firmly stuck in the inside of the connecting hole 8, thereby ensuring the firmness of the connection, and the arrangement of the adsorption cotton 11 can adsorb the liquid flowing along the arc-shaped piece 9, thereby preventing the liquid from contacting the positioning base 1.

[0020] An auxiliary opening rope 3 for assisting in adjusting the size of the opening is installed on the arc-shaped piece 9 between the protrusion 10 and the adsorbent cotton 11. Both ends of the auxiliary opening rope 3 are fixed on the arc-shaped piece 9. Therefore, when the opening operation is required again, it is only necessary to pull the auxiliary opening rope 3 outwards and then hang the end of the auxiliary opening rope 3 on the end of the protrusion 10 to complete the opening and fixing operation. The operation is simple and quick.

[0021] A hook 12 is provided at the hooking position of the connecting hook 4. The hook 12 is set in an M shape, so that the hook 12 can be more firmly connected to the tissues on both sides of the wound. A fixing ring 13 placed inside the arc-shaped piece 9 is installed at the bottom end of the hook 12 to ensure the firm fixation of the connecting hook 4, thereby preventing the connecting hook 4 from falling off from the arc-shaped piece 9.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
