Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bone wax filler. Background Technology

[0002] Bone wax is a tampon used in orthopedic, thoracic, neurosurgical, maxillofacial, and dental surgeries for hemostasis. Its mechanism of action is to physically block capillary bleeding in the bone marrow. It can be used to stop bleeding in various emergency patients with bone effusion. Currently, clinically commonly used bone wax achieves hemostasis through mechanical tamponade by sealing the bleeding pathways between bones, thus controlling bleeding from bone injuries. Its hemostatic effect is rapid and effective.

[0003] When using bone wax clinically, it needs to be slightly warmed in the hands before it can be kneaded and shaped freely. It can then be packed into areas of bone bleeding to achieve physical sealing and hemostasis. In applying bone wax, gauze is typically rolled into a ball and used to attach the bone wax. However, because the gauze or gauze ball is not properly secured, it easily loosens, affecting application and causing inconvenience, potentially prolonging surgery. Furthermore, there are issues with the accuracy of the application amount and location. Improper application can easily cause excess bone wax to overflow from the incision, increasing the risk of infection or requiring a second surgery, causing pain and financial burden for the patient. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a bone wax filler.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bone wax filler, comprising: a tube body and a pushing part; the pushing part is inserted into the tube body from one end of the tube body, and the pushing part moves along the tube body, and a clamping head is provided at one end of the pushing part placed inside the tube body, and the clamping head is clamped against the inner wall of the tube body.

[0006] Main working principle: First, bone wax, used as a tampon, needs to be appropriately heated before surgery to allow it to be kneaded and shaped freely, thus facilitating its subsequent packing into the bone bleeding site for physical sealing and hemostasis. When using the bone wax packer provided in this solution, the bone wax must first be placed inside the tube. The tube serves as the container and transport channel for the bone wax, and its design ensures that the bone wax can be stably stored and smoothly transported within it.

[0007] Next, by operating the propulsion unit, it can be moved in a predetermined direction within the tube. One end of the propulsion unit is equipped with a clamping head, a design that allows the propulsion unit to make close contact with the inner wall of the tube during movement and generate a clamping force, thereby maintaining the stable movement of the propulsion unit within the tube.

[0008] As the propulsion unit moves, its clamping head pushes the bone wax inside the tube to the other end. During this process, due to the tight contact between the clamping head and the inner wall of the tube, the bone wax is less likely to leak or overflow during transport, thus ensuring stable transport of the bone wax.

[0009] As the propulsion unit pushes the bone wax to the outlet of the tube, the doctor can accurately control the application location and amount. Due to the stable movement of the propulsion unit and the tightening action of the clamping head, the doctor can more precisely control the application process, avoiding the inconvenience and inaccuracy caused by the loosening of gauze or gauze balls in traditional methods.

[0010] Furthermore, by adjusting the speed and force of the propulsion mechanism, doctors can control the application speed and amount of bone wax as needed, thus providing greater flexibility to meet different surgical requirements.

[0011] In summary, the bone wax filler provided in this solution, through its unique design and working principle, achieves stable delivery and precise application of bone wax, improving surgical efficiency and safety, and reducing patient pain and financial burden.

[0012] Preferably, the clamping head has a double-sphere structure, in which two spheres arranged side by side are arranged along the travel direction of the propulsion part, and both spheres are pressed against the inner wall of the tube.

[0013] Preferably, a propulsion ring is provided at the end of the propulsion section away from the clamping head.

[0014] Preferably, the end of the tube body near the tightening head is provided with a rounded corner.

[0015] Preferably, the radius of the fillet is 0.2-0.4 mm.

[0016] Preferably, the end of the tube away from the clamping head gradually expands outward, and the length of the expansion is 2-5mm.

[0017] Preferably, the end of the tube away from the tightening head is provided with a gripping part, and the gripping part is provided in two sets, with the two sets of gripping parts respectively located on both sides of the tube.

[0018] Preferably, the length of the tube is 20-30cm.

[0019] Preferably, both the tube body and the propulsion section are made of austenitic stainless steel.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention, through a tight-fitting design between the clamping head and the inner wall of the tube, ensures the stability of bone wax during transport, avoiding the loosening problem caused by unsecured gauze or gauze balls in traditional methods. This improves the reliability and safety of the surgery. The surgeon can precisely control the application position and amount of bone wax by operating the propulsion unit, avoiding the problem of excess bone wax overflowing due to inaccurate application in traditional methods. This reduces the risk of infection and the possibility of secondary surgery, lowering patient suffering and financial burden.

[0022] The design of the bone wax filler makes it easier for doctors to operate and control the application of bone wax without relying on traditional tools such as gauze or gauze balls, thus improving the efficiency and convenience of the surgery.

[0023] In summary, this novel bone wax filler, through its unique design, achieves stable delivery and precise application of bone wax, improving surgical efficiency and safety, reducing patient risks and burdens, and demonstrating significant beneficial effects. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example 1

[0032] This embodiment discloses a bone wax filler, such as Figures 1-3 As shown, its structure mainly includes a tube body 1 and a propulsion part 2. The propulsion part 2 is designed to be inserted into one end of the tube body 1 and can move freely along its length inside the tube body 1. At the end of the propulsion part 2 that extends into the tube body 1, a clamping head 3 is installed. The clamping head 3 is in close contact with the inner wall of the tube body 1 to ensure that the propulsion part 2 will not fall off or shake during movement.

[0033] First, bone wax, used as a tamponade, needs to be properly heated before surgery to allow it to be easily kneaded and shaped, facilitating its subsequent packing into the bleeding site for physical hemostasis. When using the bone wax packer provided in this solution, the bone wax must first be placed inside tube 1. Tube 1 serves as the container and transport channel for the bone wax, and its design ensures that the bone wax can be stably stored and smoothly transported within it.

[0034] Next, by operating the propulsion unit 2, it can be moved in a predetermined direction within the tube body 1. One end of the propulsion unit 2 is provided with a clamping head 3. This design allows the propulsion unit 2 to make close contact with the inner wall of the tube body 1 during movement and generate a clamping force, thereby maintaining the stable movement of the propulsion unit 2 within the tube body 1.

[0035] As the propulsion unit 2 moves, its clamping head 3 pushes the bone wax inside the tube 1 to the other end of the tube 1. During this process, due to the close contact between the clamping head 3 and the inner wall of the tube 1, the bone wax is less likely to leak or overflow during transmission, thus ensuring stable transmission of the bone wax.

[0036] When the propulsion unit 2 pushes the bone wax to the outlet end of the tube 1, the doctor can accurately control the application position and amount of bone wax. Due to the stable movement of the propulsion unit 2 and the tightening effect of the clamping head 3, the doctor can more precisely control the application process of bone wax, avoiding the inconvenience and inaccuracy caused by the loosening of gauze or gauze balls in traditional methods.

[0037] In addition, by adjusting the moving speed and force of the propulsion unit 2, doctors can also control the application speed and amount of bone wax as needed, thus responding more flexibly to different surgical requirements.

[0038] In summary, the bone wax filler provided in this solution, through its unique design and working principle, achieves stable delivery and precise application of bone wax, improving surgical efficiency and safety while reducing patient suffering and financial burden. This design makes the bone wax filling process more stable and controllable, avoiding the uneven filling or overflow problems caused by direct manipulation of bone wax in traditional methods, thus improving the precision and safety of the surgery.

[0039] In some optional embodiments, the clamping head 3 is designed as a double-sphere structure, with two parallel spheres arranged along the moving direction of the propulsion part 2, and both spheres in close contact with the inner wall of the tube 1. This double-sphere structure further enhances the contact area and stability between the clamping head 3 and the inner wall of the tube 1, making the propulsion part 2 move more smoothly and reducing errors caused by shaking. This design ensures even pressure distribution when injecting bone wax. After all the bone wax is ejected, it not only conforms to the wound site to prevent secondary trauma but also assists in the even application of the bone wax. Simultaneously, the rear sphere ensures the centered position of the injector, reducing resistance during injection and withdrawal.

[0040] In some alternative embodiments, a propulsion ring 20 is installed at the end of the propulsion section 2 away from the clamping head 3. This propulsion ring 20 is designed for easy gripping and operation by the physician. By gripping and operating the propulsion ring 20, the physician can easily control the movement speed and direction of the propulsion section 2, thereby achieving precise control over the bone wax filling process.

[0041] This design makes it easier for doctors to operate the bone wax filler during surgery, improving the efficiency and convenience of the procedure.

[0042] In some alternative embodiments, a rounded corner 11 is provided at the end of the tube 1 near the clamping head 3 to reduce damage to surrounding tissues. The rounded corner 11 design makes the tube 1 smoother when inserted into the surgical site, reducing friction and damage to surrounding tissues. This design improves surgical safety and reduces the risk of tissue damage caused by the sharp edges of the tube 1.

[0043] In some optional embodiments, the radius of the fillet 11 is designed to be 0.2-0.4 mm to ensure that damage to the tissue is minimized without affecting the tight contact between the clamping head 3 and the inner wall of the tube 1. By precisely controlling the radius of the fillet 11, tissue damage can be minimized and the clamping effect maximized. This design ensures both surgical safety and the precision of the bone wax filler.

[0044] In some alternative embodiments, the end of the tube 1 away from the clamping head 3 gradually expands outward to form a flared structure, and the length of the expansion is 2-5 mm.

[0045] The funnel-shaped structure makes it easy to insert bone wax into the tube 1, which improves the doctor's comfort and ease of operation during the operation.

[0046] In some optional embodiments, two sets of grips 10 are provided at the end of the tube 1 furthest from the tightening head 3, located on both sides of the tube 1. The surgeon can simultaneously grip both sets of grips 10 with both hands to more stably control the movement and operation of the bone wax filler. This design improves the surgeon's stability and control during the procedure, contributing to more precise bone wax filling.

[0047] In some alternative embodiments, the length of the tube 1 is designed to be 20-30 cm to accommodate the needs of different surgical sites.

[0048] In some alternative embodiments, both the tube body 1 and the propulsion section 2 are made of austenitic stainless steel. Austenitic stainless steel possesses excellent corrosion resistance and biocompatibility, ensuring the stability and safety of the bone wax implant during surgery. This material selection enhances the durability and reliability of the bone wax implant while also ensuring patient safety during surgery.

[0049] 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 way. Therefore, any modifications, equivalent changes, and alterations 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 scope of the technical solution of the present utility model.
