Laparoscopic device for bloodless isolation, protection and excision of tumors

Abstract

The invention discloses a laparoscopic device for bloodless isolation, protection and excision of tumors. The device is characterized by being composed of a sealing push pipe, a guide supporting rod, an elastometric ring, a sealed sheath pipe protection bag and a base, wherein the sealing push pipe is of a hollow tubular structure, one end of the sealing push tube is provided with an internal opening, the pipe wall of the sealing push pipe is provided with leakage holes communicated with a pipe cavity, the other end of the sealing push pipe is provided with an external opening, an anti-air-leakage cap covers the external opening, and the pipe wall of the sealing push pipe is provided with an air inflation and deflation pipe and an air inflation and deflation switch; the guide supporting rod penetrates through the sealing push pipe, and one end of the guide supporting rod is connected with the elastometric ring; the elastometric ring is connected with a sealed sheath pipe protection bag mouth; a bag body is communicated with multiple sheath pipes, the sheath pipes are of tubular structures, the other ends of the sheath pipes are provided with threaded ports, and the threaded ports not only can be connected with a sealed cap, but also can be connected with the base; the base is internally provided with an unidirectional anti-air-leakage valve and a tee pipe. The device is used for laparoscopic tumor excision, not only blocks blood supply in tumor vessels, but also is isolated from other normal tissue organs in the abdominal cavity, and aims at preventing hemorrhage during operation and celiac implantation contamination by tumor cells.

Description

technical field [0001] The present invention relates to an auxiliary device for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is to puncture the abdominal wall to form multiple tiny puncture holes. After inflating the abdominal cavity, the abdominal cavity is inflated to form a space for surgical operations in the abdominal cavity and expose the tumor to be removed. Surgical instruments are used to remove the tumor from the normal tissues or organs of the human body in the abdominal cavity. During the whole process of tumor removal, solid tumors may be contaminated by tumor cells or tumor debris due to forceps tearing and other reasons. Abdominal cavity: For cystic tumors, the contents of the tumor may overflow and leak to contaminate the abdominal cavity due to forceps tearing and other reasons, thus iatrogenicly causing distant metastasis and recurrence of the tumor, which seriously threatens the life safety of patients. [0003] In order to pre...

AI Technical Summary

Problems solved by technology

[0006] Although some people try to put a simple protective bag in the abdominal cavity, that is, open the mouth of the protective bag under the operation area of ​​tumor resection, and hope that the exfoliated tumor cells, tumor contents or wound washing fluid will flow into the protective bag, but this method has The open protective measures with the opening of the intra-abdominal pocket still cannot prevent the intra-abdominal leakage of tumor pollutants

[0007] In the process of traditional laparoscopic surgery to remove tumor lesions from normal tissues and organs, due to the rich blood supply of tumor tissues, bleeding often occurs during tumor resection and tissue wounds after resection. On the one hand, when blood flows through the tumor resection wound, it is also easy to engulf the remaining tumor cells or tumor debris and flow to the abdominal cavity, resulting in tumor dissemination and metastasis

[0008] Laparoscopic surgical resection of tumor organs or tumor tissues often has a rich blood supply and is prone to bleeding. At present, there is no method to temporarily block the blood supply of the entire surgical area during surgery
