AI Technical Summary
Existing hemostatic forceps are prone to scratching the intestinal mucosa during insertion into the patient's intestine.
A minimally invasive surgical hemostat for the digestive tract was designed, comprising a round rod, a first clamp head, a second clamp head, and a drive unit. During insertion, the clamp heads are located in the receiving groove. The drive unit drives the clamp heads to move to the left and towards each other to achieve hemostasis. The front end of the round rod is bullet-shaped and the groove wall has rounded corners to avoid scratching the intestinal mucosa.
This reduces the likelihood of intestinal mucosal abrasion during insertion and removal, improving the safety and comfort of the procedure.

Abstract
Claims
1. A minimally invasive surgery vessel forceps for digestive tract, characterized in that: The device includes a round rod, a first pliers head, a second pliers head, and a driving unit. The left side of the front end of the round rod is recessed to form a receiving groove. The first pliers head and the second pliers head are both located in the receiving groove and are spaced apart in the front-back direction. The driving unit is disposed on the round rod and is used to drive the left ends of the first pliers head and the second pliers head to move to the left out of the receiving groove. The driving unit is also used to drive the first pliers head and the second pliers head to move towards each other.
2. The minimally invasive surgery vessel forceps of claim 1, wherein: A first channel is formed inside the round rod. The front end of the first channel is connected to the receiving groove, and the rear end of the first channel is connected to the rear end face of the round rod. The driving part includes a round tube, a first screw, and a second screw. The round tube is arranged in the front-back direction and can be slidably disposed in the first channel. The first screw is located in the receiving groove, and the front end of the first screw abuts against the front end face of the receiving groove. The second screw is rotatably fitted inside the round tube, and the front end of the second screw is directly opposite to the rear end of the first screw. The threads of the second screw and the first screw have opposite directions. The first pliers head has a first screw hole and is screwed onto the first screw rod. The second pliers head has a second screw hole and is screwed onto the second screw rod. The first pliers head and the second pliers head are symmetrically arranged on both sides of the connection position of the first screw rod and the second screw rod.
3. The minimally invasive surgery vessel forceps of claim 2, wherein: A first sliding groove is formed on each of the two opposite sidewalls of the first channel. The first sliding groove is arranged in the left-right direction. A first slider is slidably engaged in each of the two first sliding grooves. Both first sliders are fixedly connected to the circular tube.
4. The minimally invasive surgery vessel forceps of claim 2, wherein: The drive unit also includes a handle and a pressing plate. A second channel is formed inside the handle, which is directly opposite to the first channel. A through hole is formed in the right side of the handle, which communicates with the inner cavity of the second channel. The pressing plate is slidably fitted into the through hole. The rear end of the second screw passes through the second channel to the rear side of the handle, and the second screw is located on the left side of the pressing plate.
5. The minimally invasive surgery vessel forceps of claim 4, wherein: A second sliding groove is formed on each of the two opposite sidewalls of the second channel. The second sliding groove is arranged in the left-right direction. A second slider is slidably engaged in each of the two second sliding grooves. The two second sliders are fixedly connected to the pressing plate.
6. The minimally invasive surgery vessel forceps of claim 5, wherein: The driving part further includes an elastic part. The left end of the elastic part is fixedly connected to the left side wall of the second channel, and the right end of the elastic part abuts against the second screw. The elastic part is a structure that can extend and retract in the left and right direction. The elastic part is used to push the second screw to the right.
7. The minimally invasive surgery vessel forceps of claim 6, wherein: The elastic part includes a helical spring and a movable plate. The helical spring is located inside the second channel. The left end of the helical spring is fixedly connected to the left side wall of the second channel. The movable plate is fixedly connected to the right end of the helical spring. The movable plate abuts against the second screw to the right.
8. The minimally invasive surgery vessel forceps of claim 7, wherein: The two ends of the movable plate are respectively slidably fitted into the two second sliding grooves.
9. The minimally invasive surgery vessel forceps of claim 1, wherein: The front end of the round rod is bullet-shaped.
10. The minimally invasive surgery vessel forceps of claim 1, wherein: The connection between the wall of the receiving groove and the outer circumference of the round rod is a rounded transition.
