Description

Single-hole multichannel laparoscopic surgery sheath tube

Technical Field

The utility model relates to a wicresoft's apparatus field, concretely relates to single-port multichannel laparoscopic surgery sheath pipe.

Background

In recent years, with the development of medical technology, minimally invasive surgery is evolving from multi-hole minimally invasive surgery to single-hole minimally invasive surgery or even surface scarless surgery under natural orifice endoscopy. The single-hole multichannel minimally invasive surgery is a minimally invasive surgery with smaller trauma, which is realized by a plurality of surgical instruments entering and exiting from one incision of a human body, and the surgery needs to be carried out under the assistance of a single-hole multichannel laparoscopic surgery sheath tube.

The single-hole multi-channel laparoscopic surgery sheath tube is used for establishing a plurality of sealed surgical instrument access channels on one incision, forming pneumoperitoneum through inflation and performing surgery under an endoscope;

the traditional single-hole multi-channel laparoscopic surgery sheath tube generally comprises an operation panel with a plurality of sealed operation holes, a sleeve matched with an incision of the abdominal wall of a human body and a soft connecting part for connecting the operation panel and the sleeve. The novel rubber hose is characterized in that symmetrical lug seats are arranged on the periphery of the upper end, connected with the soft connecting portion, of the sleeve, a through hole is formed in the middle of each lug seat, a circle of check ring is arranged on the periphery of the lower end of the sleeve, and a protruding clamping portion is arranged at the position, corresponding to the lug seats, of the upper surface of each check ring. The sleeve is inserted into the wound of the abdominal wall, the check ring is positioned in the abdominal cavity to play a role in blocking, the sleeve is prevented from being separated from the wound, the sleeve is fixed by the tensioning device, and the elastic force generated by the sleeve extrudes the wound wall to play a role in sealing. The structure is complex, and when in use, the following problems can occur:

1. the operating panel of tradition type is last to have seted up four passageways, and three apparatus passageway is triangular distribution, and another one passageway setting is in the center on triangle-shaped base, adopts this kind of design, can make the operation in-process, need rotate operating panel by a wide margin, can aggravate patient's misery this moment, and the doctor operation is inconvenient. In addition, only one air hole is formed in the traditional operation panel, air inlet and air outlet both pass through the air hole, air inlet and smoke exhaust cannot be performed simultaneously in an operation, and smoke generated can affect the normal operation of the operation;

2. when the traditional operation panel is assembled with the connecting inner support, a rivet connection mode is adopted, and the quincunx plastic rivets are arranged on the panel and connected with the connecting inner support, but the mode not only leads the processing technology to be complex and defective products to be easy to appear, but also has the risk that the quincunx plastic rivets fall into the abdominal cavity in the use process;

3. due to the defects of self design, when a surgical instrument passes through the passage of the puncture outfit, the contact area between the instrument and the passage is too large, the friction force is large, and the blockage is not smooth when the instrument is inserted, so that the normal operation of the operation is influenced;

4. when the sleeve is plugged into a body, the sleeve is easy to wrinkle and twist, air leakage occurs, and meanwhile, the incision channel space is reduced, so that the normal operation of an operation is influenced;

for this reason, there is an urgent need to solve the above problems of the conventional products.
