Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel disposable tracheal retractor for open thyroid surgery made of a new material. Background Technology

[0002] According to the "2022 China Malignant Tumor Disease Burden Report" released by the National Cancer Center, the incidence of thyroid cancer in my country increased 20-fold from 2000 to 2016, becoming the 7th most common cancer in my country. National data for 2022 shows that thyroid cancer ranks third among the most common malignant tumors in Chinese women and is one of the most prevalent cancers among urban women. Surgery is the primary treatment for thyroid cancer, and central lymph node dissection is a crucial aspect of radical thyroid cancer surgery. The central region contains important structures such as the recurrent laryngeal nerve, trachea, esophagus, and parathyroid glands. During central lymph node dissection, it is essential to protect these vital organs and tissues.

[0003] Tracheal retraction during surgery is the primary method for exposing the central region. For example, Chinese utility model patent CN208892661U discloses a novel non-traumatic tracheal retractor, comprising a retractor head, a connecting rod, and a handle. The connecting rod is a tapered rod, with the thinner end connected to one end of the retractor head and the thicker end connected to one end of the handle, forming an integral structure. From the accompanying drawings, it can be seen that the two sides of the retractor head are flush with the retractor head, which makes the two sides of the retractor head relatively sharp. In other words, the two sides of the retractor head are not treated, making it easy to damage the trachea during use. Utility Model Content

[0004] This invention aims to solve the problem that retractor heads in existing technologies are prone to damaging the trachea. To achieve the above objective, and based on clinical experience, this invention provides a tracheal retractor that can reliably pull the trachea to effectively expose the central area, reduce tracheal injury, and avoid damage caused by electrical or thermal conduction.

[0005] To achieve the above objectives, this utility model proposes:

[0006] A novel disposable tracheal retractor for open thyroid surgery, comprising a retractor head and a retractor handle connected to the retractor head. The retractor head has an arc-shaped structure, with a concave arc surface on the top and a blunt, rounded head. Both sides of the retractor head curve upward to form protective wings, and the two protective wings smoothly transition into the retractor head to form an arc surface.

[0007] Preferably, the hook handle includes a gradient section and a grip section. One end of the gradient section is connected to the hook head, and the other end is connected to the grip section. The gradient section gradually increases in size from top to bottom and has a circular cross-section. The grip section has a cubic cross-section.

[0008] Preferably, the outer surface of the grip section is provided with an anti-slip area.

[0009] Preferably, the four edges of the gripping section are arc-shaped.

[0010] Preferably, the width of the gripping section is greater than the width of the gradient section.

[0011] Preferably, the width of the hook head is 8-12mm.

[0012] Preferably, the hook head comes in various sizes, including 38mm hook heads, 40mm hook heads, and 50mm hook heads.

[0013] Preferably, the hook head and hook handle are an integral structure.

[0014] The beneficial effects of this utility model are:

[0015] 1. The blunt roundness and protective side wings of this utility model can minimize or avoid cutting injuries to the pulled tissue by the head and edge of the hook head during use, thus protecting the pulled trachea and other tissues.

[0016] 2. The four edges of the grip section of this utility model are arc-shaped to protect the user and reduce or avoid hand cuts caused by force; the surface of the grip section also has anti-slip areas to increase local friction and reduce the force used by the user's hand when using the hook.

[0017] 3. The retractor of this utility model is made of polyphenylene sulfide (PPS) material, which is molded in one piece during manufacturing, reducing costs. At the same time, PPS material has the advantages of high temperature resistance, high hardness, and insulation, which can effectively avoid thermal damage to surrounding tissues caused by energy instruments during surgery, and protect surrounding important organs, especially organs and tissues such as the recurrent laryngeal nerve, parathyroid gland, and esophageal wall that are sensitive to heat damage.

[0018] 4. The tracheal hook of this utility model is for single use, which is more in line with biosafety.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0026] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should be understood in their ordinary sense by one of ordinary skill in the art to which this utility model pertains. The words “a” or “one” and similar terms used in this application specification and claims do not indicate a limitation of quantity, but rather indicate the presence of at least one. “A plurality” includes two, equivalent to at least two. The words “comprising” or “including” and similar terms mean that the element or object preceding “comprising” or “including” covers the element or object listed following “comprising” or “including” and its equivalents, and does not exclude other elements or objects. The words “connected” or “linked” and similar terms are not limited to physical or mechanical connections and can include electrical connections, whether direct or indirect. The singular forms “a,” “the,” and “the” used in this application specification and appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0027] Please refer to the following for details. Figure 1-2A novel disposable tracheal retractor for open thyroid surgery, made of a new material, includes a retractor head 1 and a retractor handle 2 connected to the retractor head 1. The retractor head 1 has an arc-shaped structure, with a concave arc surface 11 on the top and a blunt arc-shaped head 12. Both sides of the retractor head 1 curve upwards to form protective wings 13, which smoothly transition into the arc surface of the retractor head 1. The inner surface of the retractor head 1 can closely adhere to the tracheal surface, pulling the trachea away from the tracheal surface. The blunt arc-shaped head 12 and the raised protective wings 13 on both sides of the retractor head 1 minimize or avoid cutting injuries to the pulled tissue by the retractor edge during use, protecting the pulled trachea and other tissues. At the same time, the raised protective wings 13 increase the user's field of vision, making it easier for the user to observe the pulled tissue under the concave arc surface 11 of the retractor head 1, minimizing or avoiding damage to the pulled local tissue.

[0028] Furthermore, the width of the hook head 1 is 8-12mm. In this embodiment, the width of the hook head 1 is preferably 10mm. A width of 10mm is suitable for the trachea of ​​most people, that is, the contact area between the hook head 1 and the trachea is not too small, so that the force on the trachea is too concentrated and thus causes tracheal injury; the contact area between the hook head 1 and the trachea is not too large, so that the force on the trachea is too dispersed and thus makes tracheal traction more difficult. At the same time, a width of 10mm will not affect the user's operation and field of vision.

[0029] Please refer to the following for details. Figure 3 There are various models of retractor heads, including 38mm, 40mm and 50mm retractor heads. Different models can be selected according to the patient's tracheal diameter, which is more conducive to fitting the trachea and facilitating tissue traction.

[0030] Furthermore, the hook handle 2 includes a tapered section 21 and a gripping section 22. One end of the tapered section 21 is connected to the hook head 1, and the other end is connected to the gripping section 22. The tapered section 21 gradually increases in size from top to bottom, and its cross-section is circular. The gripping section 22 has a cuboid cross-section. The width of the gripping section 22 is greater than the width of the tapered section 21, making it easier for the user to grip. The outer surface of the gripping section 22 is provided with an anti-slip area 221, which consists of annular protrusions or anti-slip protrusions. This increases local friction and reduces the force required by the user's hand when using the hook. The four edges of the gripping section 22 are rounded to protect the user and reduce or avoid hand cuts caused by excessive force.

[0031] Furthermore, the retractor head 1 and retractor handle 2 are a one-piece structure, molded in one step during manufacturing, reducing costs while also increasing strength. The retractor is made of polyphenylene sulfide (PPS), a material with advantages such as high temperature resistance, high hardness, and insulation. This effectively avoids thermal damage to surrounding tissues caused by energy instruments during surgery, protecting vital organs, especially those sensitive to heat damage such as the recurrent laryngeal nerve, parathyroid glands, and esophageal wall.

[0032] This tracheal retractor is for single use only, which is more in line with biosafety standards.

[0033] This utility model relates to a novel disposable tracheal retractor for open thyroid surgery, and its working principle is explained in conjunction with the accompanying drawings:

[0034] During surgery, when central lymph node dissection is required after exposing the trachea, the retractor head 1 is placed on the outside of the trachea and kept as close to the trachea as possible. The retractor handle 2 is then pulled upwards and outwards to retract the trachea to the opposite side, thereby fully exposing the central area. During the retraction process, the position and direction of the retractor can be adjusted as needed. Furthermore, the procedure is less likely to damage nerves or adjacent tissues and organs.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
