Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a surgical retractor with a light source that can penetrate into narrow crevices. Background Technology

[0002] Surgical retractors are medical devices used in surgery to widen incisions and separate tissues to expose the surgical field. They aim to expand the surgical field and operating space, helping surgeons perform procedures with precision. Their core functions are to maintain an open incision, stabilize exposed tissues (such as the abdomen, spine, or joints), reduce tissue traction damage, and ensure clear visualization and operational safety. Depending on the application, they can be categorized into orthopedic retractors, abdominal retractors, and other types, and are widely used in orthopedics, spinal surgery, and oral and maxillofacial surgery.

[0003] In existing technologies, the retractor itself does not integrate a light source and relies on the operating room's shadowless lamp or an additional cold light source for illumination. However, narrow incisions or deep incisions are prone to forming blind spots due to tissue obstruction. Especially in narrow spaces, the angle of light incidence is limited, resulting in insufficient contrast in the surgical field. Although some retractors have built-in miniature LED lights or fiber optic light guides, the position of the light source is fixed (mostly integrated at the end of the retractor arm or the edge of the frame), and is limited by the main structure of the retractor, making it impossible to dynamically adjust the direction of illumination with the surgical operation, and making it difficult to accurately illuminate the surgical position.

[0004] Based on this, this application proposes a surgical retractor with a light source that can penetrate into narrow crevices, in order to solve at least one of the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a surgical retractor with a light source that can penetrate into narrow slits, solving the problem of poor quality of illumination of the surgical field in narrow slits and inconvenience of use of existing surgical retractors.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides a surgical retractor with a light source that can penetrate into narrow gaps, solving the problem that existing surgical retractors have poor quality of illumination of the surgical field in narrow gaps and are inconvenient to use.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] Example 1:

[0040] See Figures 1-2 As shown, a surgical retractor with a light source that can penetrate into narrow gaps includes a retractor, which includes a retractor arm 1. One end of the retractor arm 1 is provided with a retractor claw 2. The end of the retractor arm 1 near the retractor claw 2 is provided with a lighting mechanism, which includes: a lamp 3, which is provided at one end of the retractor arm 1; and a first adjustment mechanism 4, which is suitable for adjusting the lighting angle of the lamp 3.

[0041] It should be noted that: the spreading arm 1 can be configured as a long, narrow rod-like structure, suitable for surgeries in deeper surgical locations; its shape and structure can be customized according to the specific needs of the surgery; the orientation of the spreading claw 2 can be set in multiple ways to prevent the spreading arm 1 from obstructing other medical instruments from entering the incision or suture, thus affecting the implementation of the surgery; the first adjustment mechanism 4 is used to adjust the illumination angle of the lamp 3. The first adjustment mechanism 4 can fix the lamp 3 on a ball joint, rotate the ball joint to the end of the spreading arm 1, and adjust the angle by means of wire traction or micro motor driving the ball joint to rotate. The adjustment mechanism 4 can be a rotating disc connected to the end of the spreading arm 1, with the lamp 3 fixedly connected to the outer edge of the disc. The illumination angle and position of the lamp 3 can be changed by pulling the disc with a steel wire. Alternatively, the lamp 3 can be fixed on the rotating shaft of a motor, allowing for remote control of rotation and opening / closing via wired or wireless means. With the first adjustment mechanism 4 in place, medical staff can dynamically adjust the illumination angle of the lamp 3 according to the surgical procedure and the doctor's needs, improving the illumination quality of the surgical field in narrow gaps, enabling doctors to obtain clearer stereoscopic vision, reducing repeated tissue traction damage, and improving surgical efficiency and safety.

[0042] Example 2:

[0043] See Figures 2-3 As shown, a surgical retractor with a light source that can penetrate narrow gaps includes all the contents of Embodiment 1. In addition, the first adjustment mechanism 4 includes: a bellows 41 with a lamp 3 at one end; a first traction wire 42 with one end fixedly connected to the end of the bellows 41 with the lamp 3; and a handle 43 with several knobs rotatably connected to it, and the end of the first traction wire 42 away from the lamp 3 is wound around one of the knobs.

[0044] It should be noted that: the corrugated tube 41 is a tubular element with corrugated pleats, capable of bending under external force. Depending on its material, it can maintain its bent shape or return to its original shape after the external force is removed. It is commonly found in structures such as desktop microphones, bathroom showerheads, and water pipes; the specific principle will not be elaborated here. The first traction wire 42 can be made of materials such as stainless steel wire. By pulling the corrugated tube 41 with the first traction wire 42, the illumination angle and position of the lamp 3 can be adjusted, thereby improving the illumination quality of the surgical field in narrow gaps. One end of the lead wire 42 away from the lamp 3 is wrapped around one of the knobs. Medical staff can pull or loosen the first traction wire 42 by turning the knob, thereby adjusting the bending of the corrugated pipe 41. In addition, multiple first traction wires 42 and knobs can be set. One end of each first traction wire 42 is fixedly connected to different sides of one end of the corrugated pipe 41, and the other end is wrapped around the corresponding knob. This allows medical staff to precisely control the bending direction and amplitude of the corrugated pipe 41 by turning different knobs, thereby achieving better lighting effect.

[0045] In a preferred embodiment, the spreading arm 1 has multiple through holes, and the first traction line 42 is disposed inside the through holes.

[0046] It should be noted that the first traction wire 42 is installed by passing through the through hole to avoid damage and infection risks that may be caused by the first traction wire 42 coming into contact with the patient's tissue during use.

[0047] In a more preferred embodiment, the outer surface of the handle 43 is provided with anti-slip texture.

[0048] It should be noted that by setting anti-slip texture, medical staff can grip the handle 43 more securely.

[0049] Example 3:

[0050] See Figure 4 As shown, a surgical retractor with a light source that can penetrate into narrow gaps includes all the contents of Embodiments 1-2 and their preferred embodiments. In addition, the retractor claws 2 are rotatably connected to the retractor arm 1 by torsion springs.

[0051] It should be noted that the torsion spring can buffer the force generated when the opening arm 1 opens the opening claw 2 to open the patient's incision or tissue, thus avoiding damage to the patient.

[0052] In a preferred embodiment, a second traction line 44 is provided on one side of the spreading claw 2, and the end of the second traction line 44 away from the spreading claw 2 is wrapped around one of the knobs.

[0053] It should be noted that in this embodiment, the torsion spring acts to open the claw 2, causing it to rotate away from the incision or patient tissue, while the second traction line 44 enables the opening claw 2 to rotate towards the incision or patient tissue. By pulling the second traction line 44, the extent to which the opening claw 2 opens the incision or patient tissue can be controlled. The torsion spring can buffer the opening process and also reset the opening claw 2, making it easier for the opening claw 2 to enter narrow gaps. By controlling the second traction line 44 through the handle and knob, the doctor can simultaneously adjust the lighting angle and the degree of opening, improving the convenience of this application solution.

[0054] Example 4:

[0055] See Figure 5 As shown, a surgical retractor with a light source that can penetrate narrow gaps includes all the contents of Embodiments 1-3 and their preferred embodiments. In addition, the retractor arm 1 includes at least two arms, and one end of the retractor arm 1 is provided with a second adjustment mechanism 5. The second adjustment mechanism 5 is suitable for adjusting the opening and closing range of one end of the retractor arm 1 with the retractor claw 2.

[0056] It should be noted that the second adjustment mechanism 5 can be a toothed rod and an elastic plate respectively set on the opposite side of the two opening arms 1. The ends of the two opening arms 1 away from the opening claw 2 are rotatably connected. After the opening arms 1 are opened, the elastic plate is inserted into the toothed rod for limiting, ensuring that the two opening arms 1 stably open the cut. Alternatively, it can be a structure that fixes two sleeves respectively. The outer sleeve is threaded with a bolt, one end of which abuts against the inner sleeve. The sliding sleeve controls the relative position of the two opening arms 1, and is fixed by tightening the bolt. The second adjustment mechanism can make the opening arms 1 open stably.

[0057] In a preferred embodiment, the second adjustment mechanism 5 includes:

[0058] A fixed block 51 is rotatably connected to at least two supporting arms 1 at both ends of the fixed block 51. The supporting arms 1 are arranged in a centrally symmetrical manner with the fixed block 51 as the center.

[0059] Push rod 52, push rod 52 is threadedly connected to fixed block 51;

[0060] Push block 53 is rotatably connected to the end of push rod 52 away from fixed block 51;

[0061] Multiple connecting rods 54, the number of which corresponds one-to-one with the number of spreading arms 1, one end of each connecting rod 54 is rotatably connected to the push block 53, and the other end is rotatably connected to the corresponding spreading arm 1.

[0062] It should be noted that the push rod 52 is threaded to the fixed block 51. When the push rod 52 is rotated, it moves along the direction of the thread under the action of the thread, thereby pushing the push block 53 to move. This causes one end of the connecting rod 54 to push the opening arm 1 to open or close. Medical staff can control the opening and closing range of the opening arm 1 by controlling the rotation of the push rod 52.

[0063] Example 5:

[0064] A surgical retractor with a light source that can reach into narrow crevices includes all of the contents of embodiments 1-4 and their preferred embodiments. In addition, lamp 3 is a lamp assembly including a switch and a battery pack.

[0065] It should be noted that lamp 3 and the lamp assembly are powered by batteries, eliminating the need for wires and preventing wires from entering narrow gaps and affecting the patient's tissues.

[0066] In a preferred embodiment, the spreading arm 1 and the spreading claw 2 are made of stainless steel.

[0067] It should be noted that stainless steel has good corrosion resistance and biocompatibility, and its cost is relatively low, making it suitable for human use and offering high cost-effectiveness.

[0068] In summary, compared with existing technologies, it has the following beneficial effects:

[0069] 1. This application, by setting up a retractor arm, a retractor claw, and an illumination mechanism (lamp, first adjustment mechanism), enables the retractor to be used in narrow gaps / incisions. The adjustment mechanism can dynamically adjust the illumination angle of the lamp according to the surgical operation and the doctor's needs, improving the illumination quality of the surgical field in narrow gaps, enabling the doctor to obtain clearer stereoscopic vision, reducing repeated tissue traction damage, improving surgical efficiency and safety, and solving the problem of poor illumination quality and inconvenience of existing surgical retractors in narrow gaps.

[0070] 2. This application sets up a second adjustment mechanism (fixed block, push rod, push block, connecting rod) and a second traction line. Medical staff can control the opening and closing range of the spreading arm by controlling the rotation of the push rod, which is convenient to adapt to different incisions or surgical environments. The second traction line is used in conjunction with the handle to further control the opening range of the spreading claw, adapting to more complex surgical environments.

[0071] 3. This application incorporates anti-slip textures and a battery-operated light assembly. The anti-slip textures allow medical staff to grip the handle more securely, and the battery-operated light assembly eliminates the need for wires, preventing wires from entering narrow gaps and affecting patient tissues; thus improving the convenience and satisfaction of medical staff and patients in using this device.
