Description

Technical Field

[0001] This application relates to the field of percutaneous endoscopic discectomy, and more particularly to a bone wax applicator for percutaneous endoscopic discectomy. Background Technology

[0002] In minimally invasive spinal surgery, percutaneous endoscopic discectomy is required to remove a certain amount of bone tissue from the intervertebral foramen as needed. After removing part of the bone with a trephine saw, the cancellous bone surface is exposed and radiofrequency ablation is used to stop bleeding. Bone wax is a material used for fracture repair or bone defect filling. It is usually biocompatible and can support bone healing. The use of an endoscope allows for precise operation, enabling accurate application of bone wax in a small surgical area.

[0003] Chinese Patent CN219397425U discloses a bone wax hemostasis device for percutaneous endoscopic lumbar discectomy, comprising a sleeve and a core. The sleeve is disposed within the working channel of the percutaneous endoscopic lumbar discectomy unit. The sleeve has a hollow movable cavity inside, with a 60-degree bend at the distal end and a bone wax filling cavity inside. The movable cavity communicates with the bone wax filling cavity. A filling port is provided on one side of the distal end of the sleeve, and an application port is provided at the distal end. Both the filling port and the application port communicate with the bone wax filling cavity. A gripping handle is provided at the proximal end of the sleeve. The core is slidably fitted within the movable cavity of the sleeve, with a push rod connected to its distal end. The push rod has a push ball head, and its proximal end is connected to the gripping handle. This utility model provides a method for stopping bone surface bleeding under percutaneous endoscopic lumbar discectomy using bone wax, improving surgical safety and visual clarity.

[0004] Regarding the aforementioned related technologies, the inventors believe that when applying bone wax, the bone wax may concentrate on the surface of the application head, resulting in excessive or insufficient application in certain areas, thereby affecting the hemostatic effect. Furthermore, manually pushing the ball head to push the bone wax to the application opening cannot provide a stable and consistent pushing force, which may lead to inconsistent amounts of bone wax being pushed, thus affecting the uniformity and effectiveness of the application. Therefore, an intervertebral endoscopic bone wax applicator is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the technical issues in existing percutaneous endoscopic lumbar discectomy (PELD) procedures, such as bone wax concentration on the applicator surface during hemostasis, leading to excessive or insufficient application and affecting hemostasis, and the inability to provide stable pushing force by manually pushing the ball head to the applicator, thus affecting the uniformity and effectiveness of application, this application provides a bone wax applicator for PELD.

[0006] This application provides a bone wax applicator for percutaneous endoscopic discectomy, employing the following technical solution:

[0007] A bone wax applicator for percutaneous endoscopic discectomy includes a percutaneous endoscope body and a sleeve located inside the percutaneous endoscope body. The outer surface of the sleeve is provided with an applicator, which includes a spherical applicator head. The movement of the spherical applicator head applies bone wax to the surgical area.

[0008] The sleeve is equipped with a processing device, which includes a threaded push rod. The movement of the threaded push rod pushes the bone wax to the application area.

[0009] Optionally, the application device further includes a camera, which is fixedly mounted on the outer surface of the percutaneous endoscopic body, and an illumination lamp is fixedly mounted on the outer surface of the percutaneous endoscopic body.

[0010] Optionally, the spherical applicator head is fixedly installed on the outer surface of the sleeve. The outer surface of the spherical applicator head is provided with an applicator opening and a mesh groove. The outer surface of the sleeve is provided with a filling opening. The inner wall of the groove of the filling opening is threaded with a sealing plate.

[0011] Optionally, the processing device further includes a cylinder, which is fixedly installed on the inner wall of the sleeve, and a motor is fixedly installed on the inner wall of the groove of the cylinder, with a gear fixedly installed on the output shaft of the motor.

[0012] Optionally, a rack is slidably inserted into the inner wall of the groove of the cylinder, the rack meshes with the gear, and a sleeve is fixedly installed at one end of the rack, the sleeve being slidably sleeved on the inner wall of the groove of the cylinder.

[0013] Optionally, the outer surface of the sleeve rod is provided with a rotating groove, the inner wall of the cylinder is slidably inserted into the inner wall of the rotating groove through a support rod, and one end of the sleeve rod is fixedly installed with one end of the threaded push rod.

[0014] Optionally, the threaded push rod is slidably sleeved on the inner wall of the groove of the sleeve, and a handle is fixedly installed at one end of the sleeve, with a control button fixedly installed on the outer surface of the handle.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. By setting up an applicator, bone wax is applied to the surgical area. A camera is used to monitor and adjust the application process in real time. An illumination lamp provides additional lighting to the surgical area. The spherical design of the applicator head allows it to evenly contact the target surface at different angles and directions. The applicator opening is located on the outer surface of the spherical applicator head to release the bone wax. Mesh grooves are also formed on the outer surface of the spherical applicator head. These grooves help to distribute and apply the material more evenly. The filling port is located on the outer surface of the sleeve to inject bone wax into the sleeve. The inner wall of the groove of the filling port is connected to the sealing plate by threads, ensuring that the sealing plate can firmly seal the filling port. This solves the technical problem that bone wax may concentrate on the surface of the applicator head during application, resulting in excessive or insufficient application in some areas, thus affecting the hemostatic effect.

[0017] 2. By setting up a processing device, bone wax is pushed to the application area. The cylinder and sleeve are fixedly installed and secured. The motor drives the gear to rotate, and the rack meshes with the gear. The rotation of the gear drives the rack to move inside the cylinder through a sliding connection. A rotating groove is opened on the outer surface of the sleeve. The cylinder and the rotating groove are slidably connected through a support rod, allowing the sleeve to move inside the cylinder. The threaded push rod is provided with a threaded groove. The threaded groove design helps to push the bone wax more evenly. The curvature of the handle ensures comfort and control precision during operation. The control button is used to control the motor to start and is fixed on the outer surface of the handle. Users can easily press and operate when holding the handle. This solves the technical problem that when manually pushing the ball head to push the bone wax to the application port, it is impossible to provide a stable and consistent pushing force, which may lead to inconsistent bone wax pushing amount, thus affecting the uniformity and effect of application.

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] Reference Figure 1-7 A bone wax applicator for percutaneous endoscopic discectomy includes a percutaneous endoscope body 1 and a sleeve 11 located inside the percutaneous endoscope body 1. The outer surface of the sleeve 11 is provided with an applicator, which includes a spherical applicator head 3. The movement of the spherical applicator head 3 applies bone wax to the surgical area.

[0028] To monitor and adjust the application process in real time, the application device also includes a camera 2, which is fixedly installed on the outer surface of the percutaneous endoscopic endoscope body 1. An illumination lamp 21 is fixedly installed on the outer surface of the percutaneous endoscopic endoscope body 1. The camera 2 is fixedly installed to the percutaneous endoscopic endoscope body 1 for real-time monitoring and adjustment of the application process. The illumination lamp 21 helps the surgeon observe and correct the effect of the bone wax application and provides additional lighting to the surgical area to ensure the visibility and accuracy of the application operation.

[0029] To help the coating material be distributed and applied more evenly, a spherical applicator head 3 is fixedly installed on the outer surface of the sleeve 11. The outer surface of the spherical applicator head 3 is provided with an applicator opening 31 and a mesh groove 32. The outer surface of the sleeve 11 is provided with a filling opening 33. The inner wall of the groove of the filling opening 33 is threadedly connected to a sealing plate 34. The spherical applicator head 3 is fixedly installed to the sleeve 11. The spherical design allows the applicator head to contact the target surface evenly at different angles and directions. The applicator opening 31 is located on the outer surface of the spherical applicator head 3 and is used to release bone wax. The mesh groove 32 is also provided on the outer surface of the spherical applicator head 3. These grooves help the coating material be distributed and applied more evenly. The filling opening 33 is located on the outer surface of the sleeve 11 and is used to inject bone wax into the sleeve 11. The inner wall of the groove of the filling opening 33 is threadedly connected to the sealing plate 34, ensuring that the sealing plate 34 can firmly seal the filling opening 33.

[0030] By setting up an applicator, bone wax is applied to the surgical area. Camera 2 is used to monitor and adjust the applicator process in real time. Illumination lamp 21 provides additional illumination to the surgical area. The spherical design of the spherical applicator head 3 allows the applicator head to evenly contact the target surface at different angles and directions. The applicator opening 31 is located on the outer surface of the spherical applicator head 3 and is used to release bone wax. The grid groove 32 is also opened on the outer surface of the spherical applicator head 3. These grooves can help the applicator material to be distributed and applied more evenly. The filling opening 33 is set on the outer surface of the sleeve 11 and is used to inject bone wax into the sleeve 11. The inner wall of the groove of the filling opening 33 is connected to the sealing plate 34 by threads, which ensures that the sealing plate 34 can firmly seal the filling opening 33. This solves the technical problem that bone wax may concentrate on the surface of the applicator head when applying bone wax, resulting in excessive or insufficient application in some areas, thereby affecting the hemostatic effect.

[0031] In order to push the bone wax to the application area, the sleeve 11 is provided with a processing device, which includes a threaded push rod 61. The movement of the threaded push rod 61 pushes the bone wax to the application area.

[0032] To drive the gear 42 to rotate, the processing device also includes a cylinder 4, which is fixedly installed on the inner wall of the sleeve 11. A motor 41 is fixedly installed on the inner wall of the groove of the cylinder 4, and a gear 42 is fixedly installed on the output shaft of the motor 41. The cylinder 4 is fixedly installed on the sleeve 11, and the motor 41 drives the gear 42 to rotate. The gear 42 meshes with the rack 5. A sleeve rod 51 is fixedly installed on one end of the rack 5. The sleeve rod 51 is slidably sleeved on the inner wall of the groove of the cylinder 4 so as to push the bone wax through the cooperation of the gear 42 and the rack 5.

[0033] To move the rack 5, a rack 5 is slidably inserted into the inner wall of the groove of the cylinder 4. The rack 5 meshes with the gear 42. A sleeve 51 is fixedly installed at one end of the rack 5. The sleeve 51 is slidably sleeved into the inner wall of the groove of the cylinder 4. Through the meshing of the rack 5 and the gear 42, the rotation of the gear 42 drives the rack 5 to move within the slidably inserted cylinder 4, so that the sleeve 51 fixedly installed with it moves synchronously within the slidably sleeved cylinder 4. This allows the threaded push rod 61 fixedly installed with the sleeve 51 to push the bone wax to the application port 31 for application to the surgical area.

[0034] To enable the sleeve rod 51 to rotate while moving inside the cylinder 4, a rotating groove 6 is provided on the outer surface of the sleeve rod 51. The inner wall of the cylinder 4 is slidably connected to the inner wall of the rotating groove 6 via a support rod. One end of the sleeve rod 51 is fixedly installed to one end of the threaded push rod 61. The rotating groove 6 is provided on the outer surface of the sleeve rod 51, and the cylinder 4 and the rotating groove 6 are slidably connected via a support rod, so that the sleeve rod 51 rotates while moving inside the cylinder 4. This allows the bone wax to be pushed to the application port 31 by the threaded push rod 61, which is fixedly installed to the sleeve rod 51. The threaded push rod 61 is provided with a threaded groove, and the design of the threaded groove helps to push the bone wax more evenly.

[0035] To facilitate pressing and operation when the user holds the handle 7, the threaded push rod 61 is slidably sleeved on the inner wall of the groove of the sleeve 11. The handle 7 is fixedly installed at one end of the sleeve 11, and the control button 71 is fixedly installed on the outer surface of the handle 7. The curvature of the hand ensures comfort and control accuracy during operation. The control button 71 is used to control the opening of the motor 41. The control button 71 is fixed on the outer surface of the handle 7, so that the user can easily press and operate when holding the handle 7.

[0036] By setting up a processing device, bone wax is pushed to the application area. Cylinder 4 and sleeve 11 are fixedly installed and secured. Motor 41 drives gear 42 to rotate. Rack 5 meshes with gear 42. The rotation of gear 42 drives rack 5 to move inside the slidably inserted cylinder 4. Rotation groove 6 is opened on the outer surface of sleeve 51. Cylinder 4 and rotation groove 6 are slidably inserted through support rod, allowing sleeve 51 to move inside cylinder 4. Threaded push rod 61 is provided with threaded groove. The design of threaded groove helps to push bone wax more evenly. The curvature on handle 7 ensures comfort and control precision during operation. Control button 71 is used to control the opening of motor 41 and is fixed on the outer surface of handle 7. Users can easily press and operate when holding handle 7. This solves the technical problem that when applying bone wax, manually pushing the ball head to the application port 31 cannot provide a stable and consistent pushing force, which may lead to inconsistent bone wax pushing amount, thus affecting the uniformity and effect of application.

[0037] Working principle: When it is necessary to apply bone wax to the surgical area, the bone wax is filled into the sleeve 11 through the filling port 33. The sleeve 11 is then sealed by the sealing plate 34, which is threaded to the filling port 33, to prevent the bone wax from overflowing. After filling, the applicator enters the surgical area through the hole on the percutaneous endoscope body 1. The camera 2 on the percutaneous endoscope body 1 is used to monitor and adjust the application process in real time. The illumination lamp 21 provides additional lighting for the surgical area. The operator starts the motor 41 by using the control button 71 on the handle 7, which drives the gear 42 to rotate and moves the rack 5 that meshes with it in the slidingly inserted cylinder 4. Since the rotating groove 6 on the sleeve 51 is slidably inserted into the cylinder 4 through the support rod, the movement of the rack 5 causes the sleeve 51, which is fixedly installed with it, to rotate while moving, which drives the threaded push rod 61, which is fixedly installed with the sleeve 51, to move. The threaded push rod 61 is provided with a threaded groove. The design of the threaded groove helps to push the bone wax more evenly and ensures that the bone wax can be fully applied to the required area.

[0038] After the threaded pusher 61 pushes the bone wax to the application port 31 on the spherical application head 3 fixedly installed with the sleeve 11, the spherical application head 3 is moved to the surgical area to apply bone wax and stop bleeding. The spherical design of the spherical application head 3 allows the application head to contact the target surface evenly at different angles and directions. The grid grooves 32 are opened on the outer surface of the spherical application head 3. These grooves can help the application material to be distributed and applied more evenly.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
