[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0023] The inventors found in practice that the opening handles of the existing technology are mostly cylindrical. In order to observe the wound during surgery, the angle of the opening of the clamp must be quantitatively adjusted to open the surgical wound and provide a surgical observation field of view. In the process of adjusting the clamp, it is easy to cause damage to the soft tissue around the patient's wound, increase the patient's invasive operation, and increase the risk of surgery.

[0024] Based on the above findings, the present application proposes a conical spreader for use in surgical operations, wherein the hollow conical spreader handle facilitates medical staff to observe deep tissues during surgery.

[0025] Example

[0026] See Figures 1 to 5 The present application discloses a conical spreader for use in surgical operations, comprising a pliers rod hingedly mounted via a hinge shaft 3, one end of the pliers rod being a pliers handle 1, and the other end being a pliers mouth rod 2. An elastic mechanism 4 is mounted on the inner side of the two pliers handles 1, and a spreader handle 5 is vertically mounted on the same side of the two pliers mouth rods 2.

[0027] The handles 1 are curved, cylindrical structures approximately 8 cm long. The distance between the two handles 1 increases gradually from small to small, and an anti-slip structure is installed on the outer wall of the handles 1 at their largest arc to prevent the spreader from slipping out of the hand. The inner sides of both handles 1 are fixed with screws to an elastic mechanism 4, which consists of cross-shaped springs, facilitating the doctor's application of force and facilitating the repositioning of the forceps.

[0028] The two pliers rods 2 are cylindrical with a length of about 3 to 4 cm. A spreading handle 5 is vertically mounted on the same side of the front end surface of the two pliers rods 2 through a mounting frame 6, and the rear end surface is fixedly connected to the pliers handle 1.

[0029] Specifically, the mounting frame 6 includes a curved mounting plate 601 and a curved reinforcement rod 602. The curved mounting plate 601 is positioned at the viewing port end and is a curved plate with varying opening diameters. Its dimensions match those of the opening handle 5, allowing the outer surface of the opening handle 5 to fit snugly against the inner surface of the curved mounting plate 601, ensuring stability after installation and evenly transferring force to the opening handle 5. The curved reinforcement rod 602 is an annular structure with a curvature matching that of the curved mounting plate 601. It is positioned around the curved mounting plate 601, further ensuring the alignment of the curved mounting plate 601 with the opening handle 5, preventing deformation, and providing additional reinforcement.

[0030] It is worth noting that the spreader handle 5 is a hollowed-out cone, composed of two identical semi-conical plates. The end away from the jaw rod 2 forms a spreader opening 501, while the end closer to the jaw rod 2 forms an observation port 502. The diameter of the spreader handle 5 gradually increases from the spreader opening 501 to the observation port 502. A curved mounting plate 601 is mounted perpendicularly to the observation port 502 end of the spreader handle 5, ensuring that the spreader handle 5 and the jaw rod 2 are perpendicular to each other, facilitating percutaneous insertion into the wound and reaching deep within the patient's tissues. The spreader handle 5 is 8 cm long, which is suitable for most body types and can be adjusted to suit individual body types.

[0031] A typical usage of this embodiment is as follows: the doctor grasps the sterilized and disinfected spreader body, with the palm positioned on the anti-slip structure of the handle 1. The doctor then moves the body so that the spreader handle 5 is perpendicular to the patient's wound and gently inserts the spreader handle 5 into the wound. When the spreader handle 5 reaches the tissue to be observed, the doctor applies force to the handle 1. The handle 1 transmits the force to the jaw rod 2 via the hinge shaft 3, causing the jaw rod 2 to open. The force on the jaw rod 2 is evenly transmitted to the spreader handle 5 via the mounting bracket 6, causing the two half-conical plates of the spreader handle 5 to open. The doctor can then directly observe the patient's deep tissue through the observation port 502 of the spreader handle 5. If a surgical procedure is required on deep tissue, the doctor can increase the force on the handle 1, making it easier for other medical instruments to penetrate deeper into the wound and perform the surgical procedure. The spreader handle 5 also protects the side walls of the wound, preventing other medical instruments from scratching the patient's wound. After the surgery or observation is completed, the two half-conical plates are gently closed and the spreader handle 5 is then pulled out perpendicular to the wound.

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
