Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a bone wax applicator. Background Art

[0002] Bone wax is a mixture of beeswax and petrolatum mixed in a certain proportion. It is white or light yellow, has good softening properties, can be shaped after being kneaded soft by hand, and is non-toxic. Bone wax is commonly used in surgeries for bone injury bleeding. During the surgery, bone surface bleeding is the most common phenomenon. The common method of hemostasis is to apply bone wax for hemostasis. The principle of action of bone wax is to use a physical method to block the bleeding of capillaries in the bone marrow part, and to block local small capillaries through adhesion, mechanical stuffing and compression effects, so as to achieve the purpose of hemostasis.

[0003] Currently, the method for dealing with bone surface bleeding is to clamp a gauze with a hemostatic forceps to make a peanut-like spherical object, apply bone wax on the surface, and then apply it on the bone surface for hemostasis. This manual application method has low efficiency and increases the labor intensity. Of course, there are also corresponding bone wax applicators. For example, the patent with the publication number CN209005034U discloses a roller-type bone wax application device, which effectively solves the problem of low efficiency of manual application through the roller-type design and facilitates medical staff to a certain extent. However, this device does not consider that during the application, due to the different fixed parts of the human body and the areas of different bleeding parts are different. Therefore, according to its roller-type application, only a line contact application method can be achieved, and there are still defects in the application of a relatively large area.

[0004] Therefore, a bone wax applicator that can achieve line contact application and surface contact application is needed to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention designs a bone wax applicator, including: a loading cylinder, a propulsion component, a clamping component, and a silicone cylinder; the loading cylinder is a hollow structure, the propulsion component is movably installed inside the loading cylinder, an extension cylinder is fixedly installed at the front end of the loading cylinder, the clamping component is movably installed on the extension cylinder, and the silicone cylinder is detachably installed at the end of the clamping component. By clamping the silicone cylinder with the clamping component, the shape of its cross-section is changed to realize the switching between line contact application and surface contact application.

[0006] Further, the clamping component includes a clamping cylinder and a propulsion cylinder. The clamping cylinder is movably connected to the outside of the extension cylinder by threads; a clamping plate is rotatably arranged at the end of the outer side wall of the clamping cylinder. A wedge-shaped surface is arranged on the inner wall of the clamping cylinder corresponding to the clamping plate, and the wedge-shaped surface is adapted to the inclined surface fixedly arranged at the end of the extension cylinder; the propulsion cylinder is connected to the extension cylinder by threads and has an inner diameter larger than the outer diameter of the clamping cylinder; by rotating to control the forward or reverse rotation of the propulsion cylinder, the opening and closing of the clamping plate are controlled, and then the silicone cylinder is clamped to change the shape of its cross-section, realizing the switching between line contact coating and surface contact coating.

[0007] Further, the clamping component includes a fixed strip, a fixed ring, a rotating rod, and clamping petals; the fixed strip is fixedly installed on the outer wall of the loading cylinder; the rotating rods are symmetrically and movably installed on the side wall of the loading cylinder, and the clamping petals are installed on the rotating rods and extend inwards to the position of the silicone cylinder; a connecting rod is movably installed in the middle of the rotating rod, and the end of the connecting rod is fixedly installed with the fixed ring, and the fixed teeth arranged on the fixed ring and the fixed strip are meshed and fixed with each other; by controlling the forward and backward movement of the fixed ring, the clamping petals are driven to rotate inwards or outwards, and then the silicone cylinder is clamped to change the shape of its cross-section, realizing the switching between line contact coating and surface contact coating.

[0008] Further, the end of the clamping petal is in a straight-line shape.

[0009] Further, an arc-shaped rod is arranged at the end of the clamping petal, and the arc-shaped rod is an arc-shaped structure protruding outwards.

[0010] Further, the propulsion assembly includes: an electric push rod, a piston, and a sealing cover; the end of the push rod of the electric push rod is fixedly installed with the piston, the rear end of the electric push rod is connected by a rod, start-stop switches are arranged at intervals on the side wall of the rod, and a power supply button is fixedly arranged at the end of the rod; the sealing cover is movably installed on the rod and is fixed on the outer side wall of the loading cylinder by threads.

[0011] The beneficial effects of the present invention are:

[0012] The present invention designs a bone wax applicator, comprising: a loading cylinder, a propulsion assembly, a clamping component, and a silicone cylinder; the loading cylinder is of a hollow structure, the propulsion assembly is movably installed inside the loading cylinder, an extension cylinder is fixedly installed at the front end of the loading cylinder, the clamping component is movably installed on the extension cylinder, and the silicone cylinder is detachably installed at the end of the clamping component. By clamping the silicone cylinder with the clamping component to change the shape of its cross-section, the switching between line contact application and surface contact application is realized; through the provided clamping component, the cross-sectional shape of the silicone cylinder for application can be changed from circular to elliptical, so as to increase the application area during application, that is, the line contact method can be changed to the surface contact method for application. Such a setting not only effectively increases the application area and improves the application efficiency, but also can adapt to the application needs of different bone surface bleeding; compared with the traditional application method of forming a line through point contact, it can realize line contact application and surface contact application;

[0013] In addition, the overall structure of this device is made into a handheld controllable structure, which is convenient for doctors to directly hold and operate. And through the setting of the start-stop switch, the movement of the electric push rod inside is controlled to realize the extrusion filling function. By means of pressurization, the direct contact method of humans is replaced, so as to improve the hemostasis efficiency, reduce the workload, and thus reduce the amount of bleeding.

Detailed implementation mode

[0024] Embodiment 1

[0025] The present invention discloses a bone wax applicator, comprising: a loading cylinder 1, a propulsion assembly 2, a clamping component 3, and a silicone cylinder 4; the loading cylinder 1 is a hollow structure, the propulsion assembly 2 is movably installed inside the loading cylinder 1, an extension cylinder 12 is fixedly installed at the front end of the loading cylinder 1, the clamping component 3 is movably installed on the extension cylinder 12, and the silicone cylinder 4 is detachably installed at the end of the clamping component 3. By clamping the silicone cylinder 4 with the clamping component 3 to change the shape of its cross - section, the switching between line - contact application and surface - contact application is realized. By setting the clamping component 3, the cross - sectional shape of the silicone cylinder 4 for application can be changed from circular to elliptical, so as to increase the application area during application, that is, the line - contact method can be changed to the surface - contact method for application. Such a setting not only effectively increases the application area and improves the application efficiency, but also can adapt to the application requirements of different bone surface bleeding; compared with the traditional point - contact - to - line application method, it can realize line - contact application and surface - contact application.

[0026] Embodiment 2

[0027] In this embodiment, the clamping member 3 includes a clamping cylinder 31 and a propulsion cylinder 32. The clamping cylinder 31 is movably connected to the outside of the extension cylinder 12 by a thread; a clamping plate 311 is rotatably provided at the end of the outer side wall of the clamping cylinder 31, and a wedge-shaped surface 33 is provided on the inner wall of the clamping cylinder 31 corresponding to the clamping plate 311. The wedge-shaped surface 33 is adapted to the inclined surface 121 fixedly provided at the end of the extension cylinder 12; the propulsion cylinder 32 is connected to the extension cylinder 12 by a thread and has an inner diameter larger than the outer diameter of the clamping cylinder 31; by rotating the propulsion cylinder 32 in the forward or reverse direction, the opening and closing of the clamping plate 311 are controlled, and then the silicone cylinder 4 is clamped to change the shape of its cross-section, so as to realize the switching between line contact coating and surface contact coating. Specifically, the process of using it is as follows: First, the silicone tube is sleeved into the gap between the clamping cylinder 31 and the extension cylinder 12, and then the clamping cylinder 31 is rotated so that the clamping cylinder 31 can move relative to the extension cylinder 12, and the gap between the two gradually decreases, thereby realizing the clamping of the silicone tube; after the silicone tube is clamped, the propulsion cylinder 32 is rotated so that the inner wall of the propulsion cylinder 32 contacts the clamping flap 304 and forms an extrusion effect, so that the clamping plate 311 forms a clamping effect on the silicone cylinder 4, and then the cross-sectional shape of the front end of the silicone cylinder 4 is changed to achieve the transformation effect;

[0028] In this embodiment, in order to maintain the relative position of the clamping plate 311, a torsion spring can be installed at the rotating part of the clamping plate 311; at the same time, in this embodiment, the inside of the propulsion cylinder 32 is not a parallel straight cylinder shape. If it is a parallel straight cylinder shape, when forming a limiting effect on the clamping plate 311, at most it can make it parallel without forming too much extrusion inward. Therefore, its inside can be designed into an uneven or linear structure for extruding the clamping plate 311 to form a clamping effect on the inside. Through the continuous action of the clamping plate 311, the cross-sectional shape of the silicone cylinder 4 can be always maintained; it is convenient for coating.

[0029] Embodiment 3

[0030] In this embodiment, the clamping member 3 includes a fixing strip 3021, a fixing ring 301, a rotating rod 303, and clamping flaps 304. The fixing strip 3021 is fixedly installed on the outer wall of the loading cylinder 1. The rotating rod 303 is symmetrically and movably installed on the side wall of the loading cylinder 1. The clamping flaps 304 are installed on the rotating rod 303 and extend inward to the position of the silica gel cylinder 4. The middle part of the rotating rod 303 is movably installed with the connecting rod 302. The end of the connecting rod 302 is fixedly installed with the fixing ring 301. The fixing teeth 3022 provided on the fixing ring 301 and the fixing strip 3021 are engaged and fixed with each other. By controlling the forward and backward movement of the fixing ring 301, the clamping flaps 304 are driven to rotate inward or outward, thereby clamping the silica gel cylinder 4 to change the shape of its cross-section, realizing the switching between line contact coating and surface contact coating. Specifically, the working principle of the clamping member 3 is as follows: when it is necessary to change the coating method, first, pull the fixing ring 301. Under the action of the fixing ring 301, the connecting rod 302 drives the rotating rod 303 to rotate, and then drives the clamping flaps 304 to rotate inward, further clamping the silica gel sleeve. To ensure the realization of this process, the rotating rod 303 and the clamping flaps 304 are fixedly connected to each other. At the same time, regarding the clamping of the silica gel sleeve, its structure is the same as that described in Embodiment 2 (the only difference is that the clamping rod is not provided, and the rest are the same), so it will not be described in detail here. In addition, the fixing method between the fixing ring 301 and the fixing teeth 3022 on the fixing strip 3021 is a prior art, so it will not be explained in detail here (the principle is similar to the fixing of a towel clamp). In this embodiment, the end shape of the clamping flap 304 is linear, and clamping is formed through the linear setting.

[0031] However, in specific use and further analysis, the linear structure has limitations during clamping. The limitation is that after rotating a certain angle, it is easy to contact the clamping cylinder 31 that clamps the silica gel sleeve, making it unable to rotate, thereby limiting the clamping effect on the silica gel sleeve, and there are still defects to a certain extent.

[0032] To solve the above defects, in this embodiment, an arc-shaped rod 3041 is further provided at the end of the clamping flap 304. The arc-shaped rod 3041 is an arc-shaped structure protruding outward. By means of the arc-shaped protrusion, the space between the clamping flap 304 and the clamping cylinder 31 is increased, so that the clamping flap 304 can form a clamping effect with the silica gel sleeve after clamping at a small angle without contacting the clamping cylinder 31, restricting its clamping degree.

[0033] The silica gel sleeve described in Embodiment 2 can be used once. Through the one-time setting, the situation of cross-infection can be reduced, facilitating the repeated use of the device.

[0034] Embodiment 4

[0035] In this embodiment, the propelling assembly 2 can be used to propel the bone wax placed inside the loading cylinder 1. Specifically, the propelling assembly 2 includes: an electric push rod 23, a piston 24, and a sealing cover 11. The end of the push rod of the electric push rod 23 is fixedly installed with the piston 24. The rear end of the electric push rod 23 is connected by a rod. Start-stop switches 21 are arranged at intervals on the side wall of the rod, and a power button 22 is fixedly arranged at the end of the rod. The sealing cover 11 is movably installed on the rod and is fixed to the outer side wall of the loading cylinder 1 by threads. After being powered on through the power button 22, the operation of the electric push rod 23 can be controlled through the start-stop switch 21, driving the piston 24 to move forward to propel the bone wax. At the same time, the whole propelling assembly 2 is installed in a detachable manner, which is convenient for subsequent cleaning. The electric push rod 23 and the way of controlling the electric push rod 23 by the switch belong to the prior art and will not be elaborated here. In addition, in order to facilitate observing the internal situation, the loading cylinder 1 can be made transparent so that medical staff can observe the usage situation of the internal bone wax.
