Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a multifunctional retractor used during surgery. Background Art

[0002] At present, during general surgical operations, in order to facilitate the doctor to observe and treat the injured part, and to facilitate the use of various surgical instruments, it is often necessary to open a corresponding incision at the surgical site during the operation, and use a positioning device to open and position the incision. Retractor devices are mainly used to open the incision during the operation. However, in actual use, it is found that the retractor devices currently used are mostly one-piece structures. Although the structural strength and stability are good, when used, the use of these devices blocks light and space, and reduces the space for surgical operations. This undoubtedly increases the difficulty and complexity of surgical operations and may pose a potential threat to surgical results and patient safety. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0017] like Figure 1-3As shown, an embodiment of the utility model provides a multifunctional intraoperative retractor, comprising a retractor body 1, a retractor tail 2 being fixedly connected to the bottom end of the handle of the retractor body 1, a cavity 11 being opened inside the retractor body 1, the shape of the retractor body 1 being an inverted L-shape, a LED lamp bead 3 being fixedly connected to the top slot of the retractor body 1, and the LED lamp bead 3 being located above the cavity 11, a battery 5 being fixedly connected to the slot inside the handle of the retractor body 1, and the battery 5 being located on one side of the cavity 11, and the battery 5 being located above the retractor tail 2, and the battery 5 being electrically connected to the LED lamp bead 3 through a circuit, a switch 4 being installed on the side wall of the handle of the retractor body 1, and the switch 4 being located above the battery 5, and the switch 4 being electrically connected to the battery 5 through a circuit, a snap cover plate 6 being snap-connected to the slot inside the handle of the retractor body 1, and the snap cover plate 6 being located on one side of the battery 5, and the side wall of the snap cover plate 6 away from the battery 5 and the side wall of the handle of the retractor body 1 being located on the same curved surface.

[0018] The shape of the cavity 11 is an inverted L-shape, and the shape of the cavity 11 is specially designed to be an inverted L-shape, which fully considers the structural and functional requirements of the retractor. The inverted L-shaped cavity 11 not only matches the shape of the retractor body 1, but also facilitates the reasonable layout of the internal structure. More importantly, this design also reserves enough space for possible future expansion functions, so that the retractor has a strong expansion capability while maintaining a compact structure; the outer surface of the bottom end of the retractor tail 2 is provided with a thread, and the outer surface of the bottom end of the retractor tail 2 is provided with a thread, which greatly enhances the practicality of the retractor. Through the threaded interface, the doctor can easily connect various auxiliary equipment, such as smoking equipment, camera equipment, etc., to the retractor tail 2. This design not only improves the flexibility of the operation, but also enables the retractor to adapt to more complex surgical needs, becoming a truly multifunctional surgical auxiliary tool; the interior of the retractor tail 2 is hollow, and the retractor tail 2 is connected to the cavity 11. The interior of the retractor tail 2 is designed to be hollow and connected to the cavity 11. The main purpose of this design is to facilitate the access to various devices or instruments from the tail 2 of the retractor. The hollow structure provides a channel for cables and connecting tubes, thereby realizing various expansion functions. This design not only ensures the smooth access of the equipment, but also ensures the stability and safety during the operation; the top slot of the retractor body 1 is fixed and sealed by a small cover plate, and the small cover plate is located directly above the LED lamp bead 3. The sealing method of the small cover plate is ultrasonic welding or glue bonding. The top slot of the retractor body 1 is fixed and sealed by a small cover plate, and the small cover plate is located directly above the LED lamp bead 3. This design effectively protects the LED lamp bead 3 from the influence of the external environment, such as dust, moisture, etc. At the same time, the sealing method of the small cover plate adopts ultrasonic welding or glue bonding, both of which have good sealing performance, which can ensure that the LED lamp bead 3 continues to emit light stably during the operation, providing doctors with a clear surgical field of view.

[0019] Working principle: When using the multifunctional retractor during surgery, the doctor can control the battery 5 to power the LED lamp bead 3 through the switch 4, so that the LED lamp bead 3 can illuminate the patient's wound, and then the area and range of the LED lamp bead 3 can be adjusted directly by adjusting the angle of the retractor body 1, thereby greatly improving the flexibility and applicability of use. The design of the cavity 11 reserved in the retractor body 1 gives the retractor body 1 strong expansibility and versatility. Through the threaded interface of the retractor tail 2, the doctor can easily connect various auxiliary equipment according to the specific needs of the operation. For example, when it is necessary to clear the smoke in the surgical area, a smoking device can be connected; when it is necessary to record the surgical process or conduct a more in-depth inspection, a camera can be connected. This design makes the retractor not only a simple fixing and lighting tool, but also a multifunctional surgical auxiliary platform, which greatly improves the convenience and efficiency of the operation.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
