During the process of tumor resection, a minimally invasive longitudinal incision knife is generally used as the surgical instrument.

[0003] When using an existing minimally invasive longitudinal incision knife, the tumor is locally removed and then the removed tumor is extracted through a negative pressure device. This operation is repeated many times to complete the removal of the tumor. However, each time during the removal process, multiple operations are performed, which can easily lead to incomplete cutting and grasping of the tumor, which can easily cause the possibility of subsequent recurrence and has poor safety.

[0021] When the tumor is to be removed and grasped, the outer blade 1 is first inserted into the location of the tumor in the human body through the incision, and then the longitudinal cutting blade 3 is used to gradually divide the tumor into two parts for removal. During the removal process, the inside of the drainage trough 12 is pumped and pressed by the negative pressure device. At this time, the tumor that is removed in two parts enters the inside of the dividing groove 4 through the rotary cutting groove 2. At this time, the negative pressure device is used to apply pressure to the inside of the continuous pressure component. At this time, under the action of pressure, the cross-cutting blade 5 can be moved, so that the tumor entering the inside of the dividing groove 4 can be removed. After the removal, the negative pressure device is pumped and pressed, and under the connection of the telescopic rod 7, the cross-cutting blade 5 can be stored in the inside of the telescopic groove 6. At the same time, the removed tumor is pulled out through the drainage trough 12. In this way, the tumor can be removed and cleaned at one time, which solves the problem that the prior art requires multiple removal and grasping, resulting in incomplete tumor removal.

[0022] The two transverse cutting knives 5 are respectively arranged inside the two cutting grooves 4, and the outer side surfaces of the two transverse cutting knives 5 are in contact with the inner walls of the two cutting grooves 4, so that the tumor entering the interior of the cutting groove 4 can be directly removed to avoid adhesion; the transverse cutting knife 5 is movably sleeved inside the telescopic groove 6, and the length of the transverse cutting knife 5 is greater than the length of the cutting groove 4, which can increase the stability of the transverse cutting knife 5; the connecting and pressing component includes two branch grooves 8, and the two branch grooves 8 are respectively opened at the inner bottom ends of the two telescopic grooves 6. The inner bottom ends of the two branch grooves 8 are both provided with connecting grooves 9, and the inner bottom ends of the connecting grooves 9 are provided with a main groove 10, and the bottom end of the main groove 10 passes through the outer side of the outer knife member 1. The main groove 10 is inflated or pressurized by the negative pressure component, and the two branch grooves 8 can be operated simultaneously under the connection of the connecting groove 9, which greatly increases the practicality of the device.

[0023] A limit sensor 11 is embedded in the inner wall of the cutting groove 4 relative to the position of the transverse cutting knife 5, which can automatically reset the transverse cutting knife 5 after it moves to the other side of the cutting groove 4, and then reciprocate, thereby greatly improving the efficiency of tumor resection; a partition 13 is formed on the inner side of the two cutting grooves 4, and the two cutting grooves 4 are symmetrically arranged on both sides of the partition 13, so that the tumor divided into two can be treated separately, thereby improving its work efficiency; drainage grooves 14 are provided on both sides of the longitudinal cutting knife 3, and the bottom of the drainage groove 14 passes through the outer side of the bottom end of the partition 13, and a plurality of guide grooves 15 are provided on the upper surface of the rotary cutting groove 2, which can divert the secretions generated when the tumor is removed.

[0024] Working principle: insert the outer blade 1 into the tumor position in the human body through the incision, and then gradually divide the tumor into two parts for removal through the longitudinal cutting blade 3. During the removal process, the inside of the drainage groove 12 is pumped and pressed by the negative pressure device. At this time, the tumor that is cut into two parts enters the inside of the dividing groove 4 through the rotary cutting groove 2. At this time, the negative pressure device applies pressure to the inside of the continuous pressure component. At this time, under the action of pressure, the cross-cutting blade 5 can be moved, so that the tumor entering the inside of the dividing groove 4 can be removed. After the removal, the negative pressure device is pumped and pressed. Under the connection of the telescopic rod 7, the cross-cutting blade 5 can be stored in the inside of the telescopic groove 6. At the same time, the removed tumor is pulled out through the drainage groove 12. In this way, the tumor can be removed and cleaned at one time, which solves the problem that the prior art needs to perform multiple removal and grasping, resulting in incomplete removal of the tumor.
