Description

Technical Field

[0001] This utility model relates to a tracheal retractor for surgery, and more particularly to a tracheal retractor for thoracoscopic surgery. Background Technology

[0002] In thoracoscopic surgery, endoscopic retractors are often needed to assist in retracting surrounding tissues and organs to expose the surgical field. The degree of exposure of the surgical field greatly affects the quality of the surgery. Previously, five-leaf forceps were routinely used in thoracoscopic surgery. These retractors have a multi-lobed structure, which poses risks of tissue damage and embedment after opening and closing within the thoracic cavity. Furthermore, their large size and weight make them inconvenient to operate. Especially when dealing with operations involving the tracheal membranous region, due to its anatomical characteristics, the membranous region is a very fragile membranous structure, requiring gentle, smooth, and blunt instruments for retraction.

[0003] Currently, there are no surgical instruments that meet the professional requirements for tracheal retraction in thoracoscopic surgery. The commonly used five-bladed forceps are not specifically designed for tracheal retraction and have many drawbacks, posing a significant risk when retracting the tracheal membrane. To overcome this deficiency, a tracheal retractor specifically designed for thoracoscopic surgery is needed to maximize tissue protection and facilitate the surgeon's operation while fully retracting the trachea.

[0004] As can be seen from the above, the existing technical solutions have shortcomings. Therefore, it is necessary to improve the existing endoscopic retractors to meet the needs of tracheal traction and protection in thoracoscopic surgery. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tracheal retractor for thoracoscopic surgery, which can minimize the damage to tissues (especially the tracheal membrane) while meeting the traction requirements of thoracoscopic surgery, and is lightweight and easy to operate.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a tracheal retractor for thoracoscopic surgery, including a gripping part, a middle rod and an end protrusion. The cross-section of the gripping part is a regular polygon, the middle rod is an elastic rod, and the end protrusion has a smooth arc surface or a blunt surface.

[0007] Furthermore, the cross-section of the grip portion gradually increases in the direction away from the end protrusion, forming a hemispherical handle.

[0008] Furthermore, the cross-section of the grip portion is a regular hexagon, and the edges of adjacent sides extend to the hemispherical handle portion.

[0009] Furthermore, the end protrusion is provided with an anti-slip pattern.

[0010] Furthermore, the length of the end protrusion is 10mm and the width is 4mm-10mm.

[0011] Furthermore, the end protrusion is an extension along the vertical direction of the intermediate rod.

[0012] Furthermore, the extension has a length of 10 mm and a width of 4 mm.

[0013] Furthermore, the end protrusion is an arc or bend extending along the length of the intermediate rod.

[0014] Furthermore, the arc portion has a length of 10mm and a width of 8mm; the bend portion has a length of 10mm and a width of 10mm.

[0015] Furthermore, the gripping part, the intermediate rod, and the end protrusion are integrally formed, and the intermediate rod is heat-treated to form an elastic rod.

[0016] Compared with the prior art, the present invention has the following advantages: the tracheal retractor provided by the present invention can minimize the damage to tissues (especially the tracheal membrane) while meeting the traction requirements of thoracoscopic surgery, and is lightweight and easy to operate.

[0025] Please see Figure 1a and Figure 1b The tracheal retractor for thoracoscopic surgery provided by this utility model includes a gripping part 1, a middle rod 2, and an end protrusion 3. The cross-section of the gripping part 1 is a regular polygon, the middle rod 2 is an elastic rod, and the end protrusion 3 has a smooth arc surface or a blunt surface, which can protect the pulled tissue to the greatest extent.

[0026] The tracheal retractor provided by this invention can be inserted into the pleural cavity through the thoracoscopic trocar during thoracoscopic surgery. The retractor is lightweight, allowing the assistant to easily manipulate the handle to change the position and angle of the tip within the pleural cavity, thereby achieving traction on the pleural tissues to assist in exposing the surgical field.

[0027] The gripping part 1 of this utility model is selected with an appropriate size and hexagonal shape, suitable for all-round gripping. As a preferred embodiment, the cross-section of the gripping part 1 gradually increases in the direction away from the end protrusion 3, forming a hemispherical handle 4. The cross-section of the gripping part 1 is a regular hexagon, and the edges of adjacent two sides extend to the hemispherical handle 4.

[0028] The intermediate rod 2 of the tracheal hook of this invention needs to have a certain degree of elasticity so that the operation of the gripping part 1 can be transmitted to the end protrusion 3. Preferably, the gripping part 1, the intermediate rod 2 and the end protrusion 3 are integrally formed, and the intermediate rod 2 is heat-treated to achieve moderate elasticity.

[0029] The tracheal retractor for thoracoscopic surgery provided by this utility model has a protruding end portion 3 that conforms to the surface of the tissue to be pulled at an appropriate angle and curvature according to clinical needs. As a preferred first embodiment (45cm handle type, 10×4, total length of the tracheal retractor 45cm, length of the protruding end portion 10mm, width 4mm), as... Figure 1a and Figure 1b As shown, the end protrusion 3 is an extension along the vertical direction of the intermediate rod 2, roughly in the shape of a shovel. The extension may be provided with anti-slip patterns to better protect the tracheal membrane.

[0030] As a preferred second embodiment (45cm handle type 10×8, tracheal hook total length 45cm, end protrusion length 10mm, width 8mm), such as Figure 2a and Figure 2b As shown, the tracheal retractor for thoracoscopic surgery provided by this utility model has an end protrusion 3 that is an arc-shaped part extending along the length of the intermediate rod 2. The arc-shaped part may be provided with anti-slip patterns to better protect the tracheal membrane.

[0031] As a preferred third embodiment (45cm handle type 10×10, tracheal hook total length 45cm, end protrusion length 10mm, width 10mm), such as Figure 3a and Figure 3b As shown, the tracheal retractor for thoracoscopic surgery provided by this utility model has an end protrusion 3 that is a bent portion extending along the length of the intermediate rod 2. The bent portion may be provided with anti-slip patterns to better protect the tracheal membrane.

[0032] In summary, the tracheal retractor for thoracoscopic surgery provided by this utility model can meet the traction requirements of thoracoscopic surgery while minimizing damage to tissues (especially the tracheal membrane), and is lightweight and easy to operate.
