Device for taking surgical specimen through natural orifice

Abstract

The invention provides a device for taking a surgical specimen through a natural orifice. A control device is hinged to a grabbing device through a hollow connecting rod, a through sliding groove is formed in the middle of the connecting rod, a control handle moving axially is arranged in the sliding groove, and the control handle slides in the sliding groove to drive a hinge base to move forwards and backwards to control the opening and closing of the grabbing device; and the grabbing device is of a claw-shaped structure formed by a plurality of dispersedly arranged grippers, each gripper consists of a first knuckle and a second knuckle which are hinged end to end, the connecting rod is hinged to the middle of the first knuckle, the control handle is hinged to the head end of the first knuckle, the length of the control handle is greater than that of the connecting rod, the portion, between the hinged portions of the control handle and the connecting rod, of the control handle is sleeved with a spring, the second knuckle of the grabbing device is sleeved with a protective sleeve, the protective sleeve is made into two layers in the corresponding position sleeving the second knuckle, the inner layer is completely closed, the outer layer is provided with a fixing piece for the second knuckle and the protective sleeve, the end of the protective sleeve is longer than the second knuckle, and a pull rope capable of tightening a protective sleeve opening is embedded in the end of the protective sleeve.

Description

technical field [0001] The invention relates to the field of taking surgical specimens, in particular to a device for taking surgical specimens through a natural orifice. Background technique [0002] Laparoscopic surgery has been widely used in major abdominal surgeries and has gradually become normalized, but it still needs to make an incision in the abdomen to take out the specimen. In recent years, a new technique NOSES (specimen extraction through natural orifice) has been developed. Using this surgical method, specimens can be taken out through natural orifices (anus, vagina, etc.), without the need for auxiliary incisions in the abdomen, and the advantages of minimally invasiveness can be obtained. It is further sublimated, which is helpful for patients to recover after incision, get out of bed and expectorate early, and greatly promote postoperative recovery. However, this method also has some disadvantages: [0003] 1. At present, most of them make a small incisio...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, most of them make a small incision in the vagina or anus, and take it out from the incision. During the removal process, it is easy to pull the specimen violently or directly contact it, which will cause the tumor cells to fall off and plant in the abdominal cavity or the incision, resulting in tumor recurrence of

[0004] 2. The volume of gastrointestinal specimens in some patients is too large (fat mesentery in obese patients is excessively hypertrophic due to crawling hyperplasia, disease, obstruction, etc.), which leads to damage to the vagina, rectal mucosa, anal sphincter and other important organs during removal from the natural orifice. structure

[0005] 3. At present, some natural orifice protective sleeve devices have appeared clinically, but these devices can only protect the natural orifice, and cannot guarantee the implantation in the abdominal cavity (the inner opening or incision of the protective sheath during the removal process It will inevitably cause pressure on the tumor tissue, causing some tumor cells to fall off in the abdominal cavity)

In addition, the protective cover device needs to be installed first, which prolongs the operation time
