Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a magnetic plate needle finder for operating rooms. Background Technology

[0002] Surgical sutures are special needles used in surgical procedures to suture wounds, incisions, or tissues. They consist of a needle and suture. Surgical sutures are designed and used to promote wound healing, reduce bleeding, and minimize infection and complications. They are usually made of materials such as stainless steel and titanium alloys, which have high corrosion resistance, strength, and biocompatibility.

[0003] A search of Chinese Patent Publication No. CN200939172Y reveals a magnetic needle finder for operating rooms. The purpose of this invention is to design a magnetic needle finder for operating rooms that facilitates needle retrieval. Its technical solution is as follows: a handle is hinged to a magnet frame, a magnetic plate is placed on the magnet frame, the area of ​​the magnet frame is twice the area of ​​the magnetic plate, and casters are installed at the four corners of the magnet frame. It is mainly used for locating needles on the floor in the operating room.

[0004] However, in actual use, when the needle is stuck to the magnetic plate after use, medical staff need to manually remove the needle from the magnetic plate. Because the needle is sharp, improper removal can easily cause the needle to prick the staff, resulting in accidental injury risk.

[0005] Therefore, this utility model provides a magnetic plate needle finder for operating rooms. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a magnetic plate needle finder for operating rooms.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic plate needle finder for operating rooms, including a gripping rod, a cleaning component rotatably connected inside the gripping rod, an extension component rotatably connected to one end of the gripping rod, and a retraction component fixedly connected to one end of the extension component;

[0008] The clearing assembly includes a winch drum, the outer side of which is rotatably connected to a holding rod. A pull block is fixedly connected to one end of the winch drum, a pull rope is fixedly connected to the end of the winch drum away from the pull block, a connecting post is fixedly connected to the end of the pull rope away from the winch drum, and a scraper is fixedly connected to the outer side of the connecting post.

[0009] In a preferred embodiment, the retraction assembly includes a fixing block, a positioning post fixedly connected to the inner wall of the fixing block, an inner tub fixedly connected to one side of the positioning post, a retraction spring fixedly connected to the side of the positioning post near the inner tub, and a winding rope fixedly connected to the outer side of the retraction spring.

[0010] The technical effect of adopting the above technical solution is that the scraper plate is designed to remove the needles adsorbed on the magnetic plate, thereby avoiding the risk of medical staff directly touching the needles with their hands, and ensuring that the pull rope can automatically retract after use.

[0011] In a preferred embodiment, the extension assembly includes a retaining plate, one end of which is rotatably connected to a gripping rod. A magnet plate is rotatably connected inside the retaining plate, and a mounting groove is formed on the retaining plate. The outer side of the magnet plate is engaged with the mounting groove.

[0012] The technical effect of adopting the above technical solution is that it facilitates the adsorption of sewing needles in corners by extending the effect of the magnetic plate.

[0013] In a preferred embodiment, the outer side of the winch drum is rotatably connected to the gripping rod.

[0014] The technical effect of adopting the above technical solution is that it makes the operation more flexible and makes it easier for medical staff to adjust the position of the scraping plate as needed.

[0015] In a preferred embodiment, the end of the winding rope furthest from the retraction spring is fixedly connected to the connecting post.

[0016] The technical effect of adopting the above technical solution is that the fixed connection method of the rope ensures that the scraper can be stably extended and retracted during use.

[0017] In a preferred embodiment, the outer side of the scraper plate is slidably connected to the outer side of the card plate and the magnet plate.

[0018] The technical effect of adopting the above technical solution is that the scraper can slide smoothly between the card plate and the magnetic plate, thereby effectively removing the needles adsorbed on the magnetic plate.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] This invention transmits motion to the winch drum via a gripping rod, enabling the extension and retraction of the pull rope. This movement drives the connecting column and scraper plate. When the scraper plate contacts the magnetic plate, the magnetic plate attracts needles or small metal objects using its own magnetic field. This design allows for easy and safe removal of attracted needles after use, effectively avoiding the risk of puncture wounds when manually removing metal objects. Furthermore, it allows users to adjust the angle and position of the magnetic plate for more flexible operation. This not only effectively reduces safety hazards but also significantly improves work efficiency. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: a magnetic plate needle finder for operating rooms, including a gripping rod 1, a clearing component 2 rotatably connected inside the gripping rod 1, an extension component 4 rotatably connected to one end of the gripping rod 1, and a retraction component 3 fixedly connected to one end of the extension component 4;

[0033] The clearing component 2 includes a winch 21, the outer side of which is rotatably connected to the holding rod 1. A pull block 22 is fixedly connected to one end of the winch 21, and a pull rope 23 is fixedly connected to the end of the winch 21 away from the pull block 22. A connecting post 24 is fixedly connected to the end of the pull rope 23 away from the winch 21, and a scraper 25 is fixedly connected to the outer side of the connecting post 24. First, the holding rod 1 serves as a support structure. The core component of the clearing component 2 is the winch 21, which has the function of automatically winding and releasing the cable. The pull block 22 can operate the winch 21 by a simple pulling action, thereby driving the pull rope 23 and the connecting post 24 to move. The scraper 25, as an end effector, is responsible for brushing away or taking away tiny metal particles or needles from the surface of the magnetic plate.

[0034] The retraction assembly 3 includes a fixing block 31, a positioning post 32 fixedly connected to the inner wall of the fixing block 31, an inner barrel 33 fixedly connected to one side of the positioning post 32, a retraction spring 34 fixedly connected to the side of the positioning post 32 near the inner barrel 33, a winding rope 35 fixedly connected to the outer side of the retraction spring 34, and the end of the winding rope 35 away from the retraction spring 34 fixedly connected to the connecting post 24. The fixing block 31 provides a stable and secure support point, enabling the entire retraction mechanism to maintain accurate alignment and positioning. The positioning post 32 ensures that the winding rope 35 and related components can move on a precise track. This reduces wear or jamming caused by deviation. The inner tub 33 plays a protective and guiding role throughout the retraction and extension process, maintaining the structural integrity of the components. The retraction spring 34 is connected to the positioning post 32 on the side near the inner tub 33 and fits tightly with the inner tub 33. This spring is the core component of the retraction function. Its function is to automatically retract each movable part to the initial position after use through elastic force. The winding rope 35 enables the connecting post 24 to be effectively pulled back in a fixed direction when the spring retracts, ensuring the stability of the entire retraction action.

[0035] Furthermore, such as Figure 1 - Figure 3 As shown: The extension component 4 includes a clamping plate 41, one end of which is rotatably connected to the holding rod 1. A magnet plate 42 is rotatably connected inside the clamping plate 41. The outer side of the scraping plate 25 is slidably connected to the outer side of the clamping plate 41 and the magnet plate 42. A placement groove 43 is provided on the clamping plate 41. The outer side of the magnet plate 42 is engaged in the placement groove 43. The clamping plate 41 can rotate under appropriate operation, allowing the operator to easily adjust the angle and position of the magnet plate for use in different working conditions. The magnet plate 42 is responsible for generating a magnetic field to attract metal objects, such as small medical instruments that fall during surgery. The placement groove 43 is used to accommodate and fix the magnet plate 42. In this way, when encountering a corner, the magnet plate 42 can be rotated to extend to a deeper place.

[0036] Working principle:

[0037] like Figure 1 - Figure 5 As shown:

[0038] In use: First, the operator holds the handle 1 and pulls the pull block 22 of the removal component 2, triggering the rotation of the winch 21. This rotation then causes the pull rope 23 to extend or retract, thereby moving the connecting post 24 and the scraper 25 attached to its outer side. When the scraper 25 contacts the outer surface of the magnetic plate 42, the magnetic plate 42 will attract metal objects, such as needles or small instruments, that have fallen into the surgical environment through the generated magnetic field. Once the removal process is over, the operator releases the pull block 22, and the retraction spring 34 of the retraction component 3 automatically retracts. The elastic force is transmitted through the winding rope 35, which in turn pulls the connecting post 24 and the scraper 25 back to their initial position. When it is necessary to change the operating angle or position, the extension component 4 can be rotated on the handle 1 to adjust the angle with the clamping plate 41. The rotation of the clamping plate 41 causes the magnetic plate 42 to change its orientation, allowing it to contact metal objects in different positions or corners. The mounting slot 43 ensures the stability and proper positioning of the magnetic plate 42.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
