Rotary resection tool with cautery and hemostasis

The invention relates to a surgical tool, in particular to a rotary cutting tool with a burning and hemostasis function.

In recent years, under the promotion of innovative medical equipment, arthroscopic minimally invasive surgery, which can reduce the scope of wounds to avoid the risk of surgery, has begun to flourish. Generally, when performing arthroscopic surgery on an affected part such as a shoulder joint or a hip joint, since the hemostatic band cannot be tied to these parts to stop bleeding, it is necessary to rely on a tool to burn the affected part to stop bleeding during the operation. Generally, when the operation of such an affected part is performed, the resection tool and the cauterization tool are separated. Therefore, after the tissue is removed, the tool needs to be replaced to burn and stop bleeding, which is very inconvenient, and the operator must also be pervasive in the blood after the tool is replaced. Looking for a hemostatic point in the field of vision is not only inconvenient, but also increases the time of surgery and increases the risk of surgery.

At this stage, although there is a way to add a wound to place the cauterization tool to avoid the tool change, in addition to increasing the risk of wounds and healing time, this method needs to remove the removal tool after using the resection tool to remove the tissue. It can only be stopped after the hemostasis point is found by the burning tool, so it will also increase the operation time.

Therefore, the object of the present invention is to provide a kind of cauterization Rotary ablation tool for hemostasis.

Thus, the rotary ablation tool of the present invention having a burning and hemostasis function is for removing an affected part tissue. The rotary cutting tool includes a casing tube surrounding a first through groove, an inner cutting member disposed in the first through groove of the outer casing tube and rotatable relative to the outer casing tube to cut the affected part tissue, and a setting a clip in the first through slot and between the outer casing tube and the inner cutting member.

The outer casing tube includes an outer tubular body portion and an outer extension portion disposed on the outer tubular body portion and surrounding a first opening. The first opening communicates with the first through slot and the outside. The inner cutting member surrounds a second through groove, and includes an inner tube body portion, an inner extending portion disposed on the inner tube body portion and extending in the outer extending portion and surrounding a second opening, and a cutting portion disposed on the inner extension. The second opening is connected to the first opening and the second through slot. The clamping member is rotatable relative to the outer casing tube to a clamping position, and in the clamping position, the clamping member and the outer extension portion of the outer casing tube cooperate to be clamped and cauterized to extend through the first opening The affected part tissue in the second opening.

The effect of the present invention is that after the clamping member and the outer casing tube are clamped and fixed to the affected part tissue, the affected part tissue can be cauterized and hemostasis, and then the inner cutting member is rotated relative to the outer casing tube to stretch the affected part tissue. The portion within the second opening is cut away. In this way, the operator can perform fixation, cauterization and resection with a single tool, improve convenience and eliminate the need to re-find the hemostatic point, reduce the operation time and reduce the risk of surgery.
