Device, system and method for stretching and fixing intracavity tissues

Abstract

The invention provides a device for stretching and fixing intracavity tissues. The device at least comprises a first sucker and a second sucker. The first sucker is connected with a first connecting piece by a first connecting rod, and the second sucker is connected with the first connecting piece by a second connecting rod; the first connecting piece is used for adjusting angles between the firstconnecting rod and the second connecting rod. The device in an embodiment of the invention has the advantages that intracavity non-target tissues can be fixed by the aid of the suckers, accordingly,the target tissues can be exposed, the problem of fatigue due to the fact that existing non-target tissues need to be clipped by assistants in whole intracavity surgical procedures and the assistantsmaintain a single action for a long time can be solved, influence on surgical effects can be prevented, and the problem of tissue injury due to the fact that the existing non-target tissues are clipped by tissue forceps for a long time can be solved; the device can be fed into the body cavities of human bodies via main operation holes or observation holes, at least one assistant operation hole canbe omitted, accordingly, surgical wound of patients can be relieved, and postoperative rehabilitation of the patients can be accelerated.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an intracavity tissue stretching and fixing device, system and method. Background technique [0002] At present, laparoscopic surgery is to make 3 to 4 small incisions from the surgical area, mainly including the observation port, the main operation port and 1 to 2 auxiliary operation ports, and enter the body cavity through these incisions, such as the thoracic cavity and abdominal cavity, and perform specific surgical procedures . The trauma is small, and the patient recovers quickly after the operation. It is the most important operation method for surgical diseases. [0003] During the operation, an assistant needs to use tissue forceps to clamp non-target tissue through the auxiliary operation hole to expose the target tissue, so that the surgeon can perform fine operations such as dissociation, suture, and resection of the target tissue from the main operation hole...

AI Technical Summary

Problems solved by technology

[0003] During the operation, an assistant needs to use tissue forceps to clamp non-target tissue through the auxiliary operation hole to expose the target tissue, so that the surgeon can perform fine operations such as dissociation, suture, and resection of the target tissue from the main operation hole. The tissue forceps clamp and pull the non-target tissue to expose the target tissue. If the assistant clamps and pulls the non-target tissue for too long, it will cause the fatigue of the assistant, which will affect the surgical effect. Long-term clamping will inevitably cause tissue damage; at the same time, in order to achieve the pulling of non-target tissues by assistants, at least one auxiliary operation hole is often made in the patient's body, which increases the patient's surgical trauma
