Abstract
Description
Technical Field
[0001] The invention relates to the technical field of wound suturing, in particular to a bone wax applicator for a water medium channel spinal endoscope. Background Art
[0002] Bone wax is one of the commonly used hemostatic products by doctors. Its function is to seal the blood in the blood vessels together to form a stable clot, which plays a temporary sealing role, thereby achieving a good hemostatic effect. The main components of bone wax currently used in the market are vaseline and propolis (0.1%). It is solid at room temperature and its material is soft. With the progress and development of society, the application scope of bone wax is becoming wider and wider. For example, bone wax can be used for protection after tooth extraction; it can also be used when the oral mucosa is ruptured, applied to the affected area to form a barrier, and can promote wound repair; it can also be used to treat burns, frostbite, and pediatric eczema. The treatment of wound erosion and exudation. In addition, it can also be used in spinal endoscopy-assisted lumbar interbody fusion surgery, and applied to the wound surface of the bone to prevent bone bleeding.
[0003] Conventional open surgery currently uses a curved metal rod to pick up bone wax, and then squeezes it to apply it to the wound surface of the bone. However, spinal endoscopy-assisted lumbar interbody fusion is performed under a water channel medium, through a very small channel, and then deep into the spine inside the body. When using conventional curved metal rods, bone wax may be blocked by skin, ligaments, muscles or other connective tissues on the path, so it cannot be applied to the wound surface in time, and the blocked bone wax cannot be left in other parts of the human body. Medical staff need to find and remove the bone wax, which increases the operation time of medical staff.
[0004] Patent publication number CN116942218A discloses a disposable sterile bone wax pusher applicator and a bone wax heating filler. The heating filler can heat the filled bone wax into a paste, making it easy to plasticize the bone wax into a shape of suitable size. When used, the pusher applicator can pass through narrow muscle channels and push out the bone wax only when it reaches the bone surface, thereby avoiding contact between the bone wax and surrounding tissues. However, it is not suitable for endoscopic technology in water channel media, as the water flow will wash away the cooled and solidified bone wax, and the pressure cannot squeeze the bone wax into the cancellous bone seams. Summary of the invention

[0067] In this embodiment, the length ratio of the first connection part 311 and the second connection part 312 is 1:15, the first connection part 311 is connected to the movable clamp 21, and is 1 cm long, and the second connection part 312 is connected to the movable clamp handle 11, and is 15 cm long; the length ratio of the third connection part 321 and the fourth connection part 322 is 1:15, the third connection part 321 is connected to the fixed clamp 22, and is 1 cm long, and the fourth connection part 322 is connected to the fixed clamp handle 12, and is 15 cm long.
[0068] In this embodiment, the connection point between the first connection portion 311 and the second connection portion 312 , the connection point between the third connection portion 321 and the fourth connection portion 322 , and the connection point between the first cylinder 331 and the second cylinder 332 are located on the same line.

[0071] In this embodiment, the area of the threaded surface 221 accounts for 80% of the area of the movable clamping opening 21 .
[0072] In this embodiment, a return spring is provided at the hinge between the movable clamping handle 11 and the fixed clamping handle 12 .
[0073] In this embodiment, a first ring opening 111 is provided at one end of the movable clamping handle 11 away from the first connecting rod 31, and a second ring opening 121 is provided at one end of the fixed clamping handle 12 away from the second connecting rod 32, which is used for placing the operator's fingers, thereby more conveniently operating the bone wax applicator.
[0074] In this embodiment, the working principle of the bone wax applicator is:
[0075] like Figure 3 As shown, since the movable clamping handle 11 and the fixed clamping handle 12 are hinged, the movable clamping opening 21 and the fixed clamping opening 22 are hinged, the two ends of the first connecting rod 31 are respectively hinged to the movable clamping handle 11 and the movable clamping opening 21, and the two ends of the second connecting rod 32 are respectively fixedly connected to the fixed clamping handle 12 and the fixed clamping opening 22, a four-bar linkage is formed among the fixed clamping handle 11, the movable clamping handle 11, the first connecting rod 31, and the movable clamping opening 21, wherein the positions of the second hinge point 42 and the fourth hinge point 44 remain unchanged, and the positions of the first hinge point 41 and the third hinge point 43 move, so that when the movable clamping handle 11 rotates, the movable piece 213 of the movable clamping opening 21 moves toward or away from the fixed clamping opening 22.
[0076] When in use, the bone wax is placed between the movable clamp 21 and the fixed clamp 22, and two fingers are placed at the first ring 111 and the second ring 121 respectively, so that the movable clamp handle 11 rotates around the first hinge point 41 in the direction close to the fixed clamp handle 12, thereby driving the first connecting rod 31 to move in the barrel 33 in the direction close to the clamp assembly 2, and then the movable piece 213 of the movable clamp 21 is close to the fixed clamp 22, so as to clamp the bone wax. After clamping, the bone wax applicator is passed through the water medium channel and penetrated into the spine inside the body, so that the movable clamp handle 11 continues to rotate around the first hinge point 41 in the direction close to the fixed clamp handle 12, so that the movable piece 213 continues to move in the direction close to the fixed clamp 22, and then squeezes the clamped bone wax, and under the action of the threaded surface 211, the bone wax is applied from the hollow area 221 of the fixed clamp 22 to the wound surface. After the application is completed, the movable clamp handle 11 is released. If the bone wax is washed away by the water flow, the movable clamping handle 11 and the fixed clamping handle 12 can be operated to quickly clamp the washed away bone wax and apply it on the wound surface again. After the application is completed, the bone wax applicator is taken out.
[0077] Example 2
[0078] Compared with Example 1, most of them are the same, except that the angle between the first connection part 311 and the second connection part 312 is 0; the angle between the third connection part 321 and the fourth connection part 322 is 0; and the angle between the first cylinder 331 and the second cylinder 332 is 0.
[0079] Example 3
[0080] Compared with Example 1, most of them are the same, except that the angle between the first connection part 311 and the second connection part 312 is 15°; the angle between the third connection part 321 and the fourth connection part 322 is 15°; the angle between the first cylinder 331 and the second cylinder 332 is 15°.
[0081] Example 4
[0082] Compared with the embodiment 1, most of them are the same, except that the width of the edge line 222 is 0.4 mm, so that when the movable clamp 21 and the fixed clamp 22 are engaged, the edge line 222 has a certain shear force and plays a shearing role. Therefore, the applicator has both the application and shearing functions.
[0083] Example 5
[0084] like Figure 5As shown, compared with Example 4, most of them are the same, except that the two sides of the movable clamp 21 are provided with a 3-shaped notch 214 for clamping the suture needle. The notch 214 can be used to clamp the suture needle, and the applicator can have the functions of applying, shearing, and clamping at the same time. When the spinal wound inside the body is large, the tool can be used for suturing.
[0085] Although the present invention has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements may be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
