Anti-deviation assembly for thyroid surgery

Abstract

The anti-deviation assembly comprises a fixed knot, the two sides of the fixed knot are each provided with a rotating knot, the fixed knot and the rotating knots are both annular bodies, the middle portions of the annular bodies of the fixed knot and the rotating knots are jointly sleeved with an operation support, and spiral bodies are connected between the fixed knot and the rotating knots on the two sides respectively. The spiral body is used for being wound on an operation support in a spiral mode. By arranging the fixed knots, the rotating knots, the spiral bodies and the secondary force guiding bodies, when the connecting part below the common end point is subjected to deviation force caused by lateral mistaken touch, the secondary force guiding body on one side can be immediately driven to pull the rotating knots connected with the secondary force guiding body, the spiral bodies on one side are made to be tightly attached to the outer wall face of the operation support, and therefore the operation support can be fixed. The anti-skidding self-locking function of the rotating knot and the spiral body on the operation support is achieved, the influence of traction posture change on an incision part caused by external force mistaken touch is effectively avoided, and the smoothness of operation in an operation is improved.

Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and more specifically, to an anti-deviation component for thyroid surgery. Background Technology

[0002] Thyroid retractors are specialized instruments used in thyroid surgery to retract and expose the surgical field. They are usually made of stainless steel or titanium alloy and feature an arc-shaped head and a non-slip handle design. They are available in single-hook, double-hook, and adjustable types to meet the tissue retraction needs at different stages of surgery. The arc-shaped head conforms to the anatomical structure of the neck, reducing the risk of tissue damage. The non-slip handle texture facilitates stable gripping by the surgeon and prevents slippage. The single hook retractor is used for retraction of superficial tissues, such as skin and subcutaneous tissue. The double hook retractor is suitable for stable exposure of the thyroid gland or deep muscles.

[0003] In existing retractors, the bottom end is used to pull open the tissue at the patient's incision site, while the top end is suspended from a support on the side of the operating table by a medical strap or rope to form a temporary suspension end and temporarily adjust the traction posture. Therefore, during surgery, the medical strap or rope suspended below the support will be a long strip above the surgical site, forming an obstruction area. When the doctor and assistant accidentally touch the traction component laterally, it is easy to cause the temporary suspension end to slide or shift, thereby affecting the angle and posture of the retractor and causing changes in the position of the retractor. This leads to changes in the traction posture of the incision site, affecting the smoothness of the surgical operation. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide an anti-deviation component for thyroid surgery, which effectively avoids the influence of external force on the incision site causing changes in traction posture and improves the smoothness of intraoperative operation.

[0005] By setting a fixed knot, a rotating knot, a spiral, and a secondary force guide, when the connecting component below the common endpoint is subjected to a lateral mis-touch causing an offset force, the secondary force guide on one side can immediately pull the rotating knot connected to it, causing the spiral on one side to tighten and adhere to the outer wall surface of the surgical stent, thereby realizing the anti-slip self-locking function of the rotating knot and the spiral on the surgical stent, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a thyroid surgery anti-displacement component, including a fixation knot, a rotating knot on each side of the fixation knot, both the fixation knot and the rotating knot being annular bodies, and a surgical bracket being fitted together in the middle of the annular bodies of the fixation knot and the rotating knot; Each of the fixed knots and the rotating knots on both sides is connected to a spiral body, which is used to be spirally wound on the surgical support. The spiral paths of the spiral bodies on both sides have the same spin direction. The lower end of the fixed knot is connected to a main force body, and each side end of the rotating knot is connected to a secondary force body. The ends of the main force body and the secondary force bodies on both sides converge to form a common end. The lower part of the common end is used to suspend the thyroid surgical retractor directly or indirectly. The connection points between the rotating bodies on both sides and the secondary force guide bodies connected to them are located on two different sides of the surgical stent. When the thyroid surgical hook is used for suspension operations, when the connecting component below the common endpoint is subjected to a lateral offset force, it drives the secondary force guide body on one side to pull the rotating knot connected to it, causing the spiral body on one side to tighten and adhere to the outer wall surface of the surgical support, thereby realizing the anti-slip self-locking function of the rotating knot and spiral body on the surgical support.

[0007] In a preferred embodiment, the rotating knot, the helical body, and the secondary force-conducting body together constitute an anti-deviation structure, and the components in the anti-deviation structure are arranged in the following orientations: When the helix on the left extends clockwise as viewed from the left side, the connection point of the rotating knot on the left and the secondary guide body it is connected to is located on the front of the surgical stent, and the connection point of the rotating knot on the right and the secondary guide body it is connected to is located on the back of the surgical stent. When the helix on the left is arranged to extend counterclockwise as viewed from the left side, the connection point between the rotating knot on the left and the secondary guide body it is connected to is located on the back of the surgical stent, and the connection point between the rotating knot on the right and the secondary guide body it is connected to is located on the front of the surgical stent.

[0008] In a preferred embodiment, the spiral is composed of either reinforcing bars or rope.

[0009] In a preferred embodiment, the common end is used to suspend a thyroid surgical hook via a suspension body, which is composed of either a strap or a rope.

[0010] In a preferred embodiment, the primary force body and the secondary force body are composed of one of a belt or a rope.

[0011] In a preferred embodiment, both the fixed joint and the rotating joint have a through hole in the center that is adapted to the surgical support, and the fixed joint and the rotating joint are fitted with the surgical support through the through hole with a clearance fit.

[0012] The technical effects and advantages of this invention are as follows: This invention, by setting up a fixed knot, a rotating knot, a spiral, and a primary force body and a secondary force body, allows for lateral adjustment of the hook's posture during thyroid surgery retractor suspension operations under normal circumstances. When the connecting component below the common endpoint is subjected to a lateral mis-touch causing a displacement force, the secondary force body on one side immediately pulls the rotating knot connected to it, causing the spiral on one side to tighten and adhere to the outer wall of the surgical support. This achieves an anti-slip self-locking function for the rotating knot and spiral on the surgical support, effectively preventing external force mis-touch from causing changes in the traction posture of the incision site and improving the smoothness of intraoperative operations.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] As attached Figure 1 To be continued Figure 13 The thyroid surgery anti-displacement component shown includes a fixation knot 1, and a rotating knot 2 on each side of the fixation knot 1. Both the fixation knot 1 and the rotating knot 2 are annular bodies, and a surgical bracket 3 is fitted together in the middle of the annular bodies of the fixation knot 1 and the rotating knot 2. Each of the fixed knot 1 and the rotating knots 2 on both sides is connected to a spiral body 4. The spiral body 4 is used to be spirally wound on the surgical support 3. The spiral paths of the spiral bodies 4 on both sides have the same spin direction. The lower end of the fixed joint 1 is connected to a main force body 5, and each side end of the rotating joint 2 is connected to a secondary force body 6. The ends of the main force body 5 and the secondary force bodies 6 on both sides converge to form a common end. The lower part of the common end is used to suspend the surgical hook 7 directly or indirectly. With the above arrangement, it can be ensured that whether the external force causes lateral mis-contact to the secondary force body 6 above the surgical hook 7 or the connection part below the common end, the rotating joint 2 can cause the spiral body 4 on one side to rotate and contract, thereby instantly tightening the spiral body 4 to adhere to the outer wall of the surgical support 3, thereby preventing the rotating joint 2 from moving further due to the influence of external force, and playing a self-locking protection effect. The connection points between the rotating bodies on both sides and the secondary force guide bodies 6 connected to them are located on two different sides of the surgical support 3; When the surgical hook 7 is used for suspension, when the connecting part below the common endpoint is subjected to a lateral offset force, it drives the secondary guide body 6 on one side to pull the rotating knot 2 connected to it, causing the spiral body 4 on one side to tighten and adhere to the outer wall surface of the surgical support 3, thereby realizing the anti-slip self-locking function of the rotating knot 2 and the spiral body 4 on the surgical support 3.

[0017] The spiral body 4 is composed of either a rib or a rope. The common end is used to suspend the surgical hook 7 via a suspension body connection. The suspension body is composed of either a belt or a rope. The primary force body 5 and the secondary force body 6 are composed of either a belt or a rope. With the above configuration, depending on the actual situation, when a large area of ​​fixation is required, the primary force body 5 and the secondary force body 6 can be used with a belt structure to improve their fixation range and effect. When a small area of ​​flexible fixation is required, the primary force body 5 and the secondary force body 6 can be used with a rope structure to improve the flexibility of use.

[0018] When the spiral 4 is installed, it is wrapped around and fixed to the surface of the surgical stent 3, and maintains static friction contact with the surgical stent 3.

[0019] Please refer to the attached instruction manual for details. Figure 3 The components in the anti-displacement structure are arranged in the following orientations: When the spiral 4 on the left side extends clockwise as viewed from the left side, the connection point of the rotating knot 2 on the left side and the secondary guide body 6 connected to it is located on the front of the surgical support 3, and the connection point of the rotating knot 2 on the right side and the secondary guide body 6 connected to it is located on the back of the surgical support 3. When the left spiral 4 is arranged to extend counterclockwise as viewed from the left side, the connection point of the left rotating knot 2 and the secondary force guide 6 is located on the back of the surgical support 3, and the connection point of the right rotating knot 2 and the secondary force guide 6 is located on the front of the surgical support 3.

[0020] The specific implementation method is as follows: by using the above settings, it can be ensured that the spiral bodies 4 on both sides can cope with the rotation locking direction required by different actual situations, that is, the counterclockwise or clockwise direction, thereby improving the practicality of the device.

[0021] Please refer to the attached instruction manual for details. Figure 2 Both the fixed joint 1 and the rotating joint 2 have through holes 8 in the center that are adapted to the surgical support 3. The fixed joint 1 and the rotating joint 2 are fitted with the surgical support 3 through the through holes 8 with a clearance fit.

[0022] The specific implementation method is as follows: With the above setting, it can be ensured that the central fixed knot 1 can be moved laterally in the axial direction of the surgical support 3 when adjustment is required. The rotating knots 2 on both sides can also be moved laterally in the axial direction of the surgical support 3. However, when the secondary guide body 6 below the rotating knot 2 is deflected by an external force, thereby causing the rotating knot 2 to rotate, the rotating knot 2 will cause the spiral body 4 to twist and lock onto the surgical support 3 instantly, achieving the purpose of anti-slip self-locking.

[0023] Working principle of the invention: Step 1: First, the surgeon inserts the fixation knot 1 and the rotating knot 2 through the through hole 8 into the surgical support 3, and adjusts their positions as needed (when adjusting the lateral position of the fixation knot 1 and the rotating knot 2, there is no axial rotational force, thus ensuring smooth adjustment and preventing the spiral 4 from twisting and locking onto the surgical support 3). At the same time, the secondary guide body 5 and the spiral 4 on the side of the rotating knot 2 are ensured to be in a pre-tightened critical state. Then, the surgical hook 7 is tied and suspended through the common end where the ends of the main guide body 5 and the secondary guide bodies 6 on both sides converge, and the bottom end of the surgical hook 7 is fixed to a suitable area in the patient's thyroid surgical area (the suspension and fixation of the surgical hook 7 and how the bottom end is fixed to the surgical area are mature techniques in current thyroid surgery, so the details of the fixation steps will not be elaborated here).

[0024] Step 2: First, the surgeon will proceed according to the current surgical steps. Under normal circumstances, the surgeon can hold the fixed knot and rotate the knot to adjust the hook position laterally. When the doctor and assistant accidentally touch the secondary guide body 6 above the surgical hook 7 or the connecting part below the common endpoint during operation, the lateral external force can simultaneously drive the secondary guide body 6 on the same side to pull the rotating knot 2 connected above it to rotate. Then, the rotating knot 2 causes the spiral body 4 on one side to rotate and contract, thereby instantly tightening the spiral body 4 to adhere to the outer wall of the surgical support 3, thus preventing the rotating knot 2 from moving further due to external force. This provides a protective effect against displacement of the fixed knot 1 in the central position. Thus, the rotating knot 2 and the spiral body 4 achieve the anti-slip self-locking function on the surgical support 3, achieving a rapid self-locking and anti-slip safety protection effect in case of accidental contact. This effectively avoids the impact of external force accidental contact on the incision site's traction posture and improves the smoothness of intraoperative operation.

[0025] Step 3: First, the doctor and assistant can continue to complete the procedure.
