A novel safety laparoscopic thyroid retractor

Abstract

This application discloses a novel safety endoscopic thyroid retractor, relating to the field of medical device technology. It aims to address the potential for damage to blood vessels, nerves, and organs within the surgical field during the endoscopic surgical process of inserting a retractor into the thyroid region of the neck and rotating it to expose the surgical field. The thyroid retractor includes a retractor component and a skin tissue perforator. One side of the skin tissue perforator has a groove with graduations on its surface. The end of the retractor component is blunt-tipped and slidably connected to the groove. A pre-established channel is created through the graduated skin tissue perforator, and the retractor component slides along its groove, avoiding the risk of tissue damage from blind insertion. The graduations help quantify the depth of the procedure. The blunt-tipped end of the retractor component prevents tissue puncture during pulling and rotation after insertion.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a novel safety endoscopic thyroid retractor, which is used to achieve safe, precise and efficient tissue traction. Background Technology

[0002] In laparoscopic thyroid surgery, retractors are important instruments used to pull and expose the surgical area. The head of a traditional laparoscopic thyroid retractor is usually a sharp needle-like structure. Although this design is convenient for puncturing the skin to establish an operating channel, after the instrument is inserted into the body, the tip of its head can easily cause unnecessary scratches or punctures to the surrounding fragile blood vessels, nerves and other tissues during traction and rotation, posing a significant safety hazard.

[0003] To address these issues, existing technologies have proposed several improvements. For example, some solutions modify the retractor tip into a hollow tubular shape, relying on an internal puncture needle core for puncture. However, this design, to ensure the retractor wall's strength, necessitates limiting the diameter of the puncture needle core, leading to its susceptibility to bending or breakage. Furthermore, the hollow tubular tip's edge still poses a risk of tissue abrasion when moving within the tissue. Another solution adds a movable protective sleeve to the retractor tip to cover the tip after puncture. However, this structure is complex, not only difficult and costly to manufacture, but also increases the difficulty of instrument cleaning and disinfection and the risk of structural failure during surgery. Some designs also rely on lubricant, potentially causing patient allergies. Still other solutions attempt to conceal the needle-like tip within a spring-loaded protective device, achieving a "touch-and-release, remove-and-protect" function. However, this is difficult to reliably manufacture and assemble within the extremely small frontal space of the thyroid retractor, compromising structural strength and lifespan, resulting in low clinical practicality.

[0004] In summary, existing endoscopic thyroid retractors either have safety defects or sacrifice reliability, manufacturability, and ease of use due to their overly complex structures. Therefore, there is an urgent need for an endoscopic thyroid retractor that is simple in structure, safe and reliable in operation, and easy to manufacture, in order to ensure surgical outcomes while minimizing the risk of iatrogenic damage to patient tissues.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this application is to provide a novel safe endoscopic thyroid retractor to reduce damage to human tissues during surgery.

[0007] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0008] The thyroid retractor includes a retractor and a skin tissue perforator. The skin tissue perforator has a groove on one side, and the surface of the groove has graduations. The end of the retractor is blunt and is slidably connected to the groove.

[0009] The skin tissue piercing device is a slender rod. A longitudinally extending groove is machined along one side of the rod. The surface of the groove is engraved with numerical markings to indicate the puncture depth. The retractor is made of a rigid medical-grade metal. Its distal end is a smooth, blunt tip, allowing safe contact with tissue without causing injury during use. In use, the skin tissue piercing device is first inserted into the skin. Then, the end of the retractor is placed into the groove, and the retractor is slid along the groove to safely guide the tip into the body.

[0010] Furthermore, the skin tissue perforator is equipped with a puncture tip.

[0011] The puncture tip is used to puncture skin tissue to create a channel.

[0012] Furthermore, the scale is evenly distributed along the length of the skin tissue perforator and is marked with numbers.

[0013] The operator can check the depth reached by the tip of the skin tissue piercing device at any time by observing the scale on the groove, so as to avoid piercing too deeply.

[0014] Furthermore, the cross-section of the groove is U-shaped.

[0015] The cross-section of the groove matches the shape of the hook, allowing the hook to slide within the groove and guiding it during puncture.

[0016] Furthermore, the hook component is provided with a first bend, a connecting part, a second bend, and a handle.

[0017] The first bend, the connecting part, and the second bend are used to construct a suitable bending angle for easy operation, and the handle is used for gripping.

[0018] Furthermore, the bending angle of the first bend is 30 degrees.

[0019] Furthermore, the angle between the connecting part and the first bending part is 20 degrees.

[0020] Furthermore, the bending angle of the second bend is 110 degrees.

[0021] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0022] A pre-established channel is created using a graduated skin tissue puncturer, and the retractor is slidably inserted along its groove, avoiding the risk of tissue damage from blind puncture. The graduations help quantify the depth of the procedure. The retractor has a blunt tip, preventing tissue puncture during pulling and rotation after insertion. Furthermore, this blunt tip slides along the groove of the skin tissue puncturer, allowing for precise insertion. The simple structure separates the puncture and traction functions, reducing the difficulty of the surgical procedure. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1

[0030] like Figure 1 As shown, this embodiment provides a novel safety endoscopic thyroid retractor, including: a retractor 1 and a skin tissue perforator 2. The skin tissue perforator 2 has a groove 21 on one side, and the surface of the groove 21 is marked with graduations. The end 11 of the retractor 1 has a blunt head structure and is slidably connected to the groove 21.

[0031] The skin tissue piercing device 2 is a slender rod. A longitudinally extending groove 21 is machined on one side of the rod. The surface of the groove 21 is engraved with numerical graduations to indicate the puncture depth. The retractor 1 is made of a medical-grade metal material with a certain degree of rigidity. Its distal end is a smooth, blunt tip 11, which allows for safe contact with tissue without causing injury during use. In use, the skin tissue piercing device 2 is first inserted into the skin. Then, the tip 11 of the retractor 1 is placed into the groove 21, and the retractor 1 is slid along the groove 21 to safely guide the tip 11 into the body.

[0032] The skin tissue perforator 2 is equipped with a puncture tip 22.

[0033] The puncture tip 22 is used to puncture skin tissue to create a channel.

[0034] The scale is evenly distributed along the length of the skin tissue perforator 2 and is marked with numbers.

[0035] The operator can check the depth reached by the tip of the skin tissue piercing device 2 at any time by observing the scale on the groove 21, so as to avoid piercing too deeply.

[0036] The cross-section of groove 21 is U-shaped.

[0037] The cross-section of the groove 21 matches the shape of the hook 1, which facilitates the sliding of the hook 1 within the groove 21 and is used to guide the hook 1 during puncture.

[0038] The hook part 1 is provided with a first bending part 12, a connecting part 13, a second bending part 14 and a handle part 15.

[0039] The first bending portion 12, the connecting portion 13, and the second bending portion 14 are used to construct a suitable bending angle for easy operation, and the handle portion 15 is used for gripping. Example 2

[0040] As the best implementation method of this application:

[0041] The bending angle of the first bend 12 is 30 degrees.

[0042] The angle between the connecting part 13 and the first bending part 12 is 20 degrees.

[0043] The bending angle of the second bend 14 is 110 degrees.

[0044] The first bend 12 has a bending angle of approximately 30 degrees, allowing the end 11 to effectively penetrate and lift human tissue, thus creating surgical space. The angle between the connecting part 13 and the first bend 12 is approximately 20 degrees, optimizing the direction of force transmission. The second bend 14 has a bending angle of approximately 110 degrees. The key to this design is to offset the handle 15 from the forward movable part, leaving space for the main operating area and the laparoscopic lens, and preventing interference between instruments.

[0045] The working principle of this application is as follows: First, the operator holds the skin tissue perforator 2 and uses its puncture tip 22 to puncture at a predetermined location, advancing it towards the neck along the designed subcutaneous tunnel path. The operator can check the depth reached by the puncture tip 22 at any time by observing the scale on the groove 21 to avoid going too deep. Once the puncture tip 22 of the skin tissue perforator 2 reaches the target area (such as near the thyroid gland), it is kept in place.

[0046] Then, the operator holds the handle 15 of the retractor 1, aligns the blunt end 11 of the retractor 1 with and inserts it into the U-shaped groove 21 of the skin tissue puncture device 2. Along the groove 21, the operator slowly and steadily pushes the retractor 1 forward until its blunt end 11 reaches and slightly exceeds the puncture tip 22 of the skin tissue puncture device 2. During this process, the groove 21 acts as a precise guide and limiter, ensuring that the retractor 1 enters along a safe, predetermined path without deviating or damaging other tissues. After it is securely inserted, the operator slowly withdraws the skin tissue puncture device 2 to remove it.
