The utility model belongs to drainage tube technical field, specifically chest cavity multi -position drainage tube, including hose one, the inside lower surface left and right sides of hose one are all set up and have the through -going hole of through -going type, two the through -going hole between penetration has hose two, the right end of hose two penetrates hose one, the left end of hose two is set up as the connecting end, the right end of hose two curved end sets into the insertion end, the right end of hose two curved place sets up and has a plurality of through -going type through -hole, the utility model discloses buffer assembly can when hose one and hose two are subjected to the drawing to buffer, and when hose one and hose two are subjected to the drawing to drive the sliding of buffer block in the inner groove, and when the sliding of buffer block is guided through the sliding connection of guide rod and guide groove, then buffer block is extruded and is triggered to buffer the extrusion received, and make hose one and hose two are subjected to the drawing to get the buffer, and avoid the injury of patient after the drawing of hose one hose two.

This invention relates to the field of medical device technology, specifically disclosing a tumor resection device, including a resection mechanism, a body, a handle, a drive mechanism, a transmission mechanism, and an adsorption mechanism. The handle, body, and resection mechanism are sequentially connected. The drive mechanism is installed inside the handle, and the transmission mechanism is installed inside the body and connected to the drive mechanism and the resection mechanism. The drive mechanism drives the resection mechanism to perform tumor resection via the transmission mechanism. The adsorption mechanism is installed inside the handle and body, and when the resection mechanism removes the tumor, the adsorption mechanism removes the removed tumor. The tumor resection device has an elongated structure, and the maximum outer diameter of the cross-section of the tumor resection device is less than or equal to 10 mm. This invention's resection mechanism removes the tumor through the adsorption mechanism, effectively reducing the wound, alleviating patient pain, and lowering surgical risks.

The utility model relates to a positioning guider for acromioclavicular dislocation implantation surgery, which comprises a connecting part, positioning parts respectively arranged at two ends of the connecting part and a drill bit guide cylinder, a rotary sleeve in threaded fit is arranged on the outer surface, close to the bottom, of the drill bit guide cylinder, and a fixed shaft axially parallel to the rotary sleeve is arranged outside the rotary sleeve. An arc-shaped sleeve is rotationally arranged on the fixing shaft, a clamping part is arranged at the non-hinged end of the arc-shaped sleeve, and a limiting protrusion used for limiting the rotating stroke of the arc-shaped sleeve is arranged at the position, matched with the fixing shaft, of the arc-shaped sleeve. The clamping part is arranged outside the drill bit guide cylinder in a folded mode through the arc-shaped sleeve, when the drill bit is used, the unfolded clamping part can clamp an upper skeleton through relative rotation between the fixing shaft and the arc-shaped sleeve, the overall sectional area is small after the drill bit is folded, and the drill bit is convenient to use. And a wound caused in the process of placing the drill bit guide cylinder is smaller.

This invention discloses an adjustable suture looper and a vascular closure device. The adjustable suture looper includes a control handle, an adjustable bend tube, a separation mechanism, and a suture retrieval mechanism. The adjustable bend tube extends from the front end of the control handle. The separation mechanism is located at the front of the adjustable bend tube and includes a pair of openable and closable separation heads with through holes for threading surgical sutures. The suture retrieval mechanism is axially positioned on the outer layer of the adjustable bend tube. The control handle controls the bending of the adjustable bend tube and the opening, closing, and forward / backward movement of the pair of separation heads. The suture retrieval mechanism retrieves the surgical suture from the separation heads. The vascular closure device includes an adjustable suture looper and a knot pusher. The knot pusher pushes the knot on the surgical suture to the blood vessel and cuts the suture. This invention features minimal invasiveness and damage, reduces the risk of complications such as vasculitis, allergies, and thrombus dislodgement, and provides a long-lasting vascular closure effect.
