Barrier type single-hole laparoscope operation channel

Abstract

The invention relates to a medical instrument, in particular to an operation channel used in an single-hole laparoscope operation, and aims at solving the technical problems that an existing single-hole laparoscope operation channel is large is size, operation instruments are hard to swing, instruments and operation channels are interfered with one another, and an application range is narrow. The barrier type single-hole laparoscope operation channel comprises an outer shell, instrument holes, an air inlet path, and an exhaust path and is characterized in that the outer shell is composed of barrel-shaped hard sheath and a soft cap capable of covering the hard sheath, barriers are arranged in the hard sheath and separate an inner cavity of the hard sheath into a plurality of division zones, and the soft cap is provided with a plurality of instrument holes. The operation channel has the advantages that the size of the operation channel is minimized, the structure of a gas leakage preventing device is simplified, larger instrument swing space is provided, instrument collision disturbance is reduced, and the diameter of the operation channel is reduced. The operation channel can be used for various single-hole laparoscopic instruments including pre-bending hard instruments.

Description

technical field [0001] The invention relates to a medical device, in particular to a surgical channel used in single-hole laparoscopic surgery. Background technique [0002] Compared with traditional multi-hole laparoscopic surgery, single-port laparoscopic surgery has fewer incisions and is more beautiful. It is one of the development directions of minimally invasive surgery. The surgical channel is a key instrument for single-port laparoscopic surgery. Single-port laparoscopic surgery needs to place a surgical channel in the only incision. There are multiple instrument holes on the surgical channel, and multiple operating instruments such as surgical forceps and surgical scissors are placed. In order to prevent air leakage from the instrument holes on the surgical channel, the surgical channel should be With anti-leakage device. The existing single-port laparoscopic surgical channel has the following deficiencies in the operation: 1. The fulcrum of the surgical channel t...

AI Technical Summary

Problems solved by technology

The existing single-port laparoscopic surgical channel has the following deficiencies in the operation: 1. The fulcrum of the surgical channel to the instrument is located outside the abdomen, and the instrument swings on this fulcrum, while the diameter of the surgical channel located in the abdominal wall section is small, which limits the ability to operate the instrument. The range of swing makes the scope of surgery narrow; 2. Due to the lack of separation, the ends of the instruments in the intra-abdominal section tend to cross each other, causing mutual interference; 3. At present, most of the common instrument holes need the support and guidance of the tubular structure, which makes the structure large and easy to operate. Collision interference, and the tubular structure increases the frictional resistance of the instrument, which affects the entry and exit of the instrument and the surgical operation; 4. Many surgical channels need to insert additional anti-leakage trachea components, which increases the volume, increases the difficulty of operation, and affects the swing and entry and exit of the operating instrument 5. Surgical channels with a single-layer anti-leakage structure have poor sealing effect and large viscous resistance to operating instruments, which affects the smoothness of surgical instruments entering and leaving; 6. Some surgical channels can only be used in conjunction with expensive and easily damaged bendable Laparoscopic instruments, but cannot be used for simple and reliable pre-bent rigid laparoscopic instruments; 7. The structure of the surgical channel is complex, easily damaged, and the price is high; 8. The design of some surgical channels has difficulties in the feasibility of production and application

These deficiencies are unfavorable factors affecting the development of single-port laparoscopy

At present, there is no surgical channel that can solve the above problems at the same time, which is the main reason affecting the development of single-port laparoscopy
