Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical devices in orthopedics, and particularly relates to a bone wax hemostat under an endoscope for spinal UBE endoscopic surgery. Background Art
[0002] In spinal biportal endoscopic (UBE) surgery, when removing bone tissues such as laminae, the bone surface is prone to bleeding, which affects the surgical field under the endoscope and even causes a red screen, seriously affecting the surgical operation and even possibly leading to the serious consequence of accidental injury to the spinal nerve. Radiofrequency hemostasis has an unsatisfactory hemostatic effect on bone surface bleeding, and excessive radiofrequency hemostasis on the bone surface may cause bone necrosis, while bone wax hemostasis has a relatively definite hemostatic effect on bone surface bleeding. The method of applying bone wax to the bleeding bone surface by sticking it to the head of a nerve dissector in traditional open surgery is very difficult to operate under the endoscope. During the transmission of bone wax, it is easily detached due to the impact of water and the obstruction of soft tissues, unable to complete the hemostatic action of applying bone wax to the bone surface, resulting in poor hemostatic effect or even failure. The bone wax hemostat under the UBE endoscope protects the bone wax through a channel, avoiding the obstruction of soft tissues and water pressure during the process, enabling the bone wax to reach the bleeding area of the bone surface smoothly, and at the same time achieving a better bone surface hemostatic effect by applying pressure through a push rod. Summary of the Invention
[0003] Aiming at the problems existing in the above-mentioned prior art, the utility model provides a bone wax hemostat under an endoscope for spinal UBE endoscopic surgery, aiming to deliver the bone wax to the designated area by using the protection of the bone wax outer sleeve protection tube body and be able to apply pressure and smear the bone wax onto the bone surface to achieve the purpose of hemostasis.
[0004] To achieve the above purpose, the specific scheme of the utility model is as follows:
[0005] The bone wax hemostat under an endoscope for spinal UBE endoscopic surgery includes a bone wax pushing handle, a bone wax outer sleeve protection tube body for installing bone wax, and a push rod body adapted to the bone wax outer sleeve protection tube body. The bone wax pushing handle is connected to one end of the push rod body, and a rubber piston is provided at the other end of the push rod body and is movably connected inside the bone wax outer sleeve protection tube body.
[0006] Further, the bone wax outer sleeve protection tube body is composed of a first circular tube part and a conical tube part. The conical tube part is connected to the proximal end of the first circular tube part, and the distal edge of the first circular tube part is rounded. The length of the push rod body is greater than or equal to the sum of the lengths between the first circular tube part and the conical tube part;
[0007] Alternatively, the bone wax outer protective tube body is composed of a first circular tube portion, a conical tube portion, an arc-shaped circular tube portion, and a second circular tube portion. The conical tube portion is connected to the proximal end of the first circular tube portion. One end of the arc-shaped circular tube portion is connected to the distal end of the first circular tube portion, and the other end is connected to the second circular tube portion. The second circular tube portion is provided with an inclined surface, and the edge of the inclined surface is rounded. The length of the push rod body is greater than or equal to the sum of the lengths between the first circular tube portion and the conical tube portion.
[0008] Further, the taper of the conical tube portion is 20° to 60°, and the included angle formed by the inclined surface and the bottom end of the second circular tube portion is 75° to 85°.
[0009] Further, the sum of the lengths between the first circular tube portion and the conical tube portion is 100 to 150 mm.
[0010] Further, the inner diameter of the second circular tube portion is 3 to 5 mm, the outer diameter is 5 to 8 mm, the length between the arc-shaped circular tube portion and the second circular tube portion is 20 to 30 mm, and the length of the second circular tube portion is 3 to 5 mm.
[0011] Further, the bone wax pushing handle and the bone wax outer protective tube body are respectively provided with anti-slip lines, and the outer side of the bone wax outer protective tube body is provided with scale marks.
[0012] Further, the push rod body and the bone wax pushing handle are connected to form a T shape.
[0013] Advantages of the present invention
[0014] The structure of the endoscopic bone wax hemostat for spinal UBE surgery of the present utility model is delicate and the design is unique and novel. Based on the principle of a "syringe", the bone wax is delivered to the designated area by the protection of the bone wax outer protective tube body and can apply pressure and smear the bone wax onto the bone surface to achieve the purpose of hemostasis, avoiding the risk that the bone wax is stuck to the head of the nerve dissector in the traditional open surgery and other methods to deliver the bone wax to the bleeding area on the bone surface, which is likely to cause the bone wax to fall off midway in the surgical area and unable to reach the designated area for hemostasis, and it may be difficult to find after falling off. Moreover, the bone wax hemostat of the present utility model has a simple structure and is convenient to use, and is suitable for popularization. Brief description of the drawings
