Description

Technical Field

[0001] This utility model relates to surgical instruments, and more particularly to a retractor specifically designed for subclavian endoscopic thyroid surgery. Background Technology

[0002] The subclavian laparoscopic thyroid retractor is a retraction instrument specifically designed for subclavian laparoscopic thyroidectomy. Its main function is to lift the anterior neck muscles (such as the sternohyoid / thyrohyoid muscles) in a confined operating space, expose the thyroid surgical area, and help establish a stable instrument operating channel, avoiding frequent adjustments to the tamper position.

[0003] Currently, thyroid surgical retractors used clinically are typically U-shaped. A fume extraction tube is located at the bottom of the hook arm, with one end extending to the front of the hook arm and the other to the rear, for connection to external suction equipment. Due to the small surgical incision and narrow instrument access channels, this fume extraction tube at the bottom of the hook arm obstructs the surgical field of view, occupies the instrument access channels, and poses a risk of accidental damage to the recurrent laryngeal nerve and carotid sheath. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide a retractor specifically designed for subclavian endoscopic thyroid surgery.

[0025] The following describes in detail, with reference to the accompanying drawings, a special retractor for subclavian endoscopic thyroid surgery according to an embodiment of this utility model.

[0026] Reference Figures 1 to 3 As shown, the retractor for subclavian endoscopic thyroid surgery provided according to an embodiment of the present invention includes a hook body 10 and a suspension body 11.

[0027] Specifically, the hook 10 includes a hook arm 101 and a connecting arm 102. The hook arm 101 is used to insert into an incision on the patient's skin to stretch the epidermis, thereby opening the incision. One end of the connecting arm 102 is connected to the hook arm 101. Exemplarily, the hook 10 can be made of a metal material such as stainless steel. The hook arm 101 is generally straight to allow for easy insertion through an incision below the patient's clavicle. During the surgery, the tip of the hook arm 101 is placed deep to the anterior neck muscles (such as the sternohyoid and thyrohyoid muscles) to lift and pull these muscle tissues and the superficial skin, effectively opening the surgical incision and creating a stable and clear surgical field and operating channel, exposing the thyroid surgical area for subsequent surgical instrument entry and manipulation. One end of the connecting arm 102 is connected to the hook arm 101, for example, through integral molding or welding.

[0028] The suspension body 11 is connected to the other end of the connecting arm 102 for connection to the mechanical suspension mechanism to apply tension to the hook body 10. The suspension body 11 can be designed as a ring, hook, or structure with a through hole H102. Its main function is to serve as a reliable connection structure for suspension or fixation to mechanical suspension mechanisms commonly used in operating rooms. A continuous and stable tension is applied through this mechanical suspension mechanism, acting on the suspension body 11 and transmitted to the entire hook body 10, thereby achieving continuous traction on the target tissue.

[0029] The hook arm 101 is equipped with a smoke exhaust channel H101, which extends along the length of the hook arm 101 to the connecting arm 102. The connecting arm 102 has a suction port H104 connected to one end of the smoke exhaust channel H101. The bottom surface of the hook arm 101 has at least one smoke exhaust hole H103 to allow smoke to enter the smoke exhaust channel H101 and be extracted through the suction port H104. In other words, to achieve effective smoke absorption, at least one smoke exhaust hole H103 is provided on the bottom surface of the hook arm 101, i.e., the side facing the thyroid gland and the smoke-generating area during surgery. These smoke exhaust holes H103 are directly connected to the internal smoke exhaust channel H101. In practical applications, multiple smoke exhaust holes H103 can be evenly distributed along the length of the hook arm 101 to increase the smoke absorption range. Correspondingly, a suction port H104 is provided on the connecting arm 102, which communicates with the end of the smoke exhaust channel H101. The suction port H104 can be conveniently connected to an external suction device.

[0030] In specific surgical applications, when surgeons use energy instruments such as electrocautery or ultrasonic scalpels for tissue cutting and hemostasis, smoke that can obstruct the field of vision is generated. At this time, a negative pressure is created by an external suction device connected to the suction port H104, and the smoke from the surgical area is rapidly drawn into the internal smoke exhaust channel H101 through the smoke exhaust hole H103 on the bottom surface of the hook arm 101. It then flows through the connecting arm 102 via this channel and is finally discharged from the surgical area through the suction port H104.

[0031] According to the embodiments of this utility model, the retractor for subclavian laparoscopic thyroid surgery incorporates a smoke extraction channel H101 within the hook arm 101, connecting it to the suction port H104 on the connecting arm 102. This design does not obstruct the surgical operating channel, resulting in a wider and clearer surgical field under the endoscope; the increased surgical operating space facilitates the entry and exit of surgical instruments and precise manipulation; furthermore, it reduces the risk of accidental injury during surgery, significantly improving surgical safety. Therefore, this retractor achieves a high degree of structural integration and optimization without affecting the original traction and smoke extraction efficiency, making the surgical process safer and more efficient.

[0032] In one embodiment of this utility model, the upper surface of the hook arm 101 is provided with an anti-slip structure. By adding an anti-slip structure to the upper surface of the hook arm 101, the traction stability of the retractor during surgery is greatly enhanced, preventing accidental slippage of the retractor and improving its safety and reliability throughout the entire surgical procedure.

[0033] For example, the anti-slip structure includes multiple anti-slip ridges 101a, which are spaced apart along the length of the hook arm 101, and each anti-slip ridge 101a extends along the width of the hook arm 101. This spaced arrangement ensures effective anti-slip points are provided at different locations on the hook arm 101. The cross-section of the anti-slip ridge 101a is a trapezoidal cross-section with a rounded apex or a smooth semi-circular cross-section, ensuring sufficient friction while maintaining a rounded surface to avoid cutting tissue.

[0034] When the hook arm 101 applies a pulling force to the tissue, the pulled tissue naturally rests against these transverse anti-slip ridges 101a, effectively resisting tissue movement due to its own elasticity and intraoperative disturbance. Compared to general surface roughening treatment, this ridged structure provides stronger gripping force, making the hook positioning extremely stable and reliable, thus improving the reliability, safety, and efficiency of the surgery.

[0035] In one embodiment of this invention, the front end of the hook arm 101 curves upward to form a bent portion 1011. In this embodiment, the upward-curving bent portion 1011 provides a more effective and stable traction effect. Once the hook arm 101 enters the incision, the bent portion 1011 provides a reliable anchoring point, effectively preventing the hook from shifting position during continuous traction. This allows for continuous and stable opening and maintenance of the surgical space, ensuring subsequent laparoscopic observation and delicate manipulation.

[0036] In one embodiment of this utility model, the retractor for subclavian laparoscopic thyroid surgery further includes a suction tube 12. One end of the suction tube 12 is fixed to the outer side of the connecting arm 102 and communicates with the suction port H104. The other end of the suction tube 12 has a quick connector 121 for connecting to a suction device.

[0037] The connecting arm 102, acting as a hook, is exposed outside the patient's body. Its outer surface is where the suction tube 12 is installed, without interfering with the surgical area. The suction tube 12 can be fixed using methods such as integrated welding to ensure its internal channel is fully aligned and connected to the pre-set suction port H104 on the connecting arm 102, thus forming a smoke extraction path from the inside of the hook arm 101 to the outside of the suction tube 12. The quick-connect fitting 121 can be a barbed fitting or a snap-fit ​​fitting, its structure allowing nurses or doctors in the operating room to quickly insert or screw on the hose of a standard hospital negative pressure suction device, creating an airtight connection and thus improving ease of use.

[0038] In one embodiment of this utility model, the hook arm 101 is provided with a through hole H102 extending through the hook arm 101, and the through hole H102 extends along the length direction of the hook arm 101. Advantageously, there are two through holes H102, and the two through holes H102 are spaced apart along the width direction of the hook arm 101.

[0039] On the one hand, if tissue bleeding accumulates on the upper surface of the hook arm 101 during surgery, it can easily reduce the friction between the hook arm 101 and the tissue, leading to problems such as accidental slippage. The through-hole H102 allows blood from the tissue to flow out, thus keeping the interface between the hook arm 101 and the tissue relatively dry and reducing the possibility of the hook arm 101 slipping. On the other hand, when the hook arm 101 pulls the tissue upward, the compressed soft tissue will slightly embed into these through-holes H102, further increasing the friction between the two and further reducing the possibility of the hook slipping during traction.

[0040] Preferably, there are multiple smoke exhaust holes H103, which are located between two through holes H102 and spaced apart along the length of the hook arm 101. This ensures both the speed and range of smoke exhaust, and the generated smoke can be quickly and effectively removed.

[0041] In one embodiment of the present invention, the suspension body 11 is L-shaped, and one end of the suspension is connected to the other end of the connecting arm 102. The other end of the suspension body 11 is bent to form a hook portion 111, and the suspension body 11 and the hook body 10 form a "5" shape.

[0042] The suspension body 11 can be made of the same material as the hook body 10, such as medical-grade stainless steel. One end of it is securely connected to the end of the connecting arm 102 away from the hook arm 101 through integral molding or high-strength welding. The hook part 111 at the other end of the suspension body 11 can be quickly and safely attached to the arm end of a mechanical suspension mechanism commonly used in operating rooms, and can be connected by rubber bands, bandages, etc.

[0043] When the L-shaped suspension body 11 is combined with the hook body 10 and connecting arm 102, the entire retractor forms a figure-five structure. This figure-five design causes the final suspension point (i.e., the hook part 111) to be spatially offset from the central axis of the retractor body, moving it to a more outward and upward position, thus away from the area directly above the surgical incision. This effectively reduces the obstruction and interference of the retractor on the surgeon's line of sight or operation, providing a more open and unobstructed space for the insertion of the endoscope and the precise operation of surgical instruments. At the same time, the figure-five structure ensures the stability of the connection between the retractor and the suspension mechanism, guarantees the continuous and stable application of traction force, and improves safety and reliability.

[0044] Advantageously, the hook portion 111 is provided with a connection hole H11 for connecting to a mechanical suspension mechanism, which facilitates connection to the mechanical suspension mechanism, for example, by means of a bolt or other connector passing through the connection hole H11.

[0045] Preferably, the hook arm 101 is 10 to 15 cm long, and the width of the front end of the hook arm 101 is 1.5 to 3 cm. More preferably, the hook arm 101 is 12 cm long, which can meet the surgical needs of most people undergoing unilateral and bilateral thyroid lobectomy (approximately the distance from below the clavicle to the trachea). The width of the front end of the hook arm 101 is 2 cm, which can both fully lift the thyroid gland, expand the surgical operating area, and meet the requirements of a small incision (4 cm).
