Background

Percutaneous endoscopic discectomy (PETD) through intervertebral foramen approach is a common spine minimally invasive surgery mode at present, and has the advantages of local anesthesia, small wound, less bleeding, no influence on spine stability and the like. When the soft tissue on the bone surface is stripped and intervertebral foramen is formed by trepan sawing in the operation, the bleeding on the bone surface is often caused, and the operation visual field is not clear. The operation of hemostasis is difficult because the wound of the operation approach is small. The radio frequency ablation technique is often not satisfactory in hemostasis. Moreover, the risk of spinal nerve root and cauda equina nerve injury can be increased by descending radio frequency ablation hemostasis in unclear operative field by operators. Bone wax is a commonly used hemostatic material for bone fracture ends, and has been widely used in various bone surface hemostatic operations in orthopedic surgeries. However, because the PETD surgical channel is deep, the incision is small, and sterile water is used to dilate soft tissues, bone wax cannot be sufficiently and effectively applied to the bleeding part on the bone surface in the operation.

In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

As shown in fig. 1 to 3, the present embodiment provides an auxiliary hemostatic device for smearing bone wax under a percutaneous spinal endoscope, comprising a handle 10, a needle cylinder 20 and an inner needle 30, wherein one end of the needle cylinder 20 is detachably connected to one top end of the handle 10, one end of the inner needle 30 is connected to the other top end of the handle 10, and the other end of the inner needle 30 is inserted into the needle cylinder 20 for connecting bone wax 50.

Specifically, the handle 10 is U-shaped, the handle 10 includes a first holding portion 11, a second holding portion 12 and an elastic portion 13, the elastic portion 13 is an elastic member, and the first holding portion 11 and the second holding portion 12 are both provided with holding circular holes 14 into which fingers are inserted. When the thumb, the index finger and the middle finger are inserted into the circular holding holes 14, respectively, and force is applied to the center of the palm, the elastic portion 13 has elasticity, so that the tips of the first holding portion 11 and the second holding portion 12 are pressed to approach each other.

The needle cylinder 20 is provided with a second screw inlet 21 at one end close to the first hand-held part 11, the handle 10 is provided with a first screw inlet 15 at the top end of the first hand-held part 11, the first screw inlet 15 and the second screw inlet 21 are connected through a screw 40, and the connection is more stable due to the threaded connection of the handle 10 and the needle cylinder 20. The end of the barrel 20 remote from the first screw inlet 15 is used for insertion into a surgical portal. Preferably, the end surface of the syringe 20 inserted into the surgical portal is beveled, and the end surface of the bone wax 50 is also beveled and is inclined at an angle corresponding to the bevel of the syringe 20.

The end of the inner needle 30 extending out of the cylinder 20 is provided with a blunt thread and is threadedly coupled to the tip of the second handle 12. The inner needle 30 is provided with a sharp-nose thread at one end of the needle cylinder 20 and is arc-shaped, so that the arc-shaped thread end of the inner needle 30 is fully connected with the bone wax 50 to prevent the bone wax 50 from falling off. Preferably, the end of the inner needle 30 connected to the bone wax 30 has a flat structure to facilitate the application of the bone wax 30 during surgery.

In this embodiment, the length of the inner needle 30 is greater than that of the needle cylinder 20, so that the inner needle 30 has a sufficient length, and the end of the inner needle 30 connected with the bone wax 50 can be moved out of the needle cylinder 20 by the pushing of the handle 10.

The installation method of the device comprises the following steps: when the syringe is installed, the first screw inlet 15 on the handle 10 is firstly connected with the second screw inlet 21 of the syringe 20 through the screw 40, and then the end of the blunt thread of the inner needle 30 is inserted into the syringe 20 from the end of the syringe 20 far away from the handle 10, so that the end of the blunt thread of the inner needle 30 extends out of the syringe 20 and is in threaded connection with the top end of the second holding part 12 of the handle 10, and simultaneously the end of the arc-shaped sharp-mouth thread of the inner needle 30 is connected with the bone wax 50 and is placed in the syringe 20.

The use of this hemostasis device: when bone wax 50 needs to be applied in an operation, the thumb, the index finger and the middle finger of the right hand pass through the two handheld circular holes 14 of the handle 10, the device is held by the right hand, one end, far away from the handle 10, of the needle cylinder 20 passes through an operation entrance gently, and moves to the position where the bone wax 50 needs to be applied, the thumb, the index finger and the middle finger exert force towards the center of the palm simultaneously, at the moment, the elastic part 13 of the handle 10 is elastically deformed, the top ends of the first handheld part 11 and the second handheld part 12 of the handle 10 are close to each other, and because the needle cylinder 20 is connected with the top end of the first handheld part 11, the inner needle 30 is connected with the top end of the second handheld part 12, when the handle 10 is held tightly, the inner needle 30 can drive the bone wax 50 to move out of the needle cylinder 20 and apply. After the smearing operation is finished, the fingers are released, and the inner needle 30 drives the bone wax 50 to return to the syringe 20 due to the elastic action of the elastic part 13.

The hemostatic device is stably supported by the screw thread, the use is easy, and the cleaning, disinfection and bone wax replacement 50 after the operation are also more convenient. Overall structure is reasonable, easily dismantles and the equipment, and whole operation process just can be accomplished to the one hand, easy operation, and the application is convenient, and the reliability is high.
