Description

Barrier single hole laparoscopic surgery channel

Technical field

The invention relates to a medical device, in particular to a surgical channel for single hole laparoscopic surgery.

Background technique

Laparoscopic surgery has a small incision, which has become the mainstream surgical procedure and gradually replaces open surgery. Traditional laparoscopic surgery requires 2 to 6 puncture incisions, typically 3 to 5 puncture incisions. In order to further reduce the trauma, a single-hole laparoscopic surgery occurred. Single-hole laparoscopic surgery requires only one puncture incision, which is less and more beautiful than traditional laparoscopic surgery, and is one of the development directions of surgical minimally invasive surgery. The surgical access is the key device for single-hole laparoscopic surgery. Single-hole laparoscopic surgery requires a surgical channel to be placed in a single incision. There are multiple instrument holes in the surgical channel, and multiple surgical instruments such as surgical forceps and surgical scissors are placed. In order to prevent air leakage from the instrument hole on the surgical channel, the surgical channel should have an air leakage prevention device. Single-port laparoscopy can be used for laparoscopic laparoscopic surgery, extraperitoneal laparoscopic surgery, and retroperitoneal laparoscopic surgery.

technical problem

At present, the single-port laparoscopic surgical channel has the following disadvantages: 1. The surgical instruments such as surgical forceps need to pass through the instrument hole or the instrument short tube on the surgical channel, and the instrument hole or the instrument short tube forms the fixation of the surgical instrument swing. The fulcrum, the surgical instrument swings with this pivot point, and the range of the swing depends on the inner diameter of the channel. For most of the current surgical channels, there is a problem that the pivot point of the instrument is located near the outer mouth of the channel, and the smallest inner diameter of the channel is located in the middle or inner section due to The distance between the fulcrum and the middle section is large, which limits the swing of the instrument and makes the scope of surgery narrow. two At present, the instrument hole on most surgical channels is placed on the short tube of the instrument, and the short tube of the instrument is connected to the base. The short tube and the base play a supporting role for the surgical forceps and the like while limiting its activities. three Each surgical channel contains a plurality of short tubes of a short tube with a leak-proof gas cap, and a plurality of short tubes of the instruments are densely arranged, resulting in local crowding, especially when the instruments are oscillated during operation. Interference has increased the difficulty of surgery. Fourth, the surgical channels need to have a sealing function. The anti-leakage structure of many surgical channels is bulky, causing mutual crowding and interference. There are also many surgical channels that need to insert additional tubular anti-leakage components, which increases congestion and increases operational difficulties. Affect the swing and access of the operating device. 5. Due to the lack of separation inside the channel, the laparoscopic instrument rods in the abdominal cavity easily cross each other, causing mutual interference. Sixth, some surgical channels can only be used with expensive and vulnerable laparoscopic instruments, and are not suitable for simple and reliable pre-bending hard laparoscopic instruments, which increases the cost of surgery and the difficulty of surgery. 7. The design concept of some surgical channels has difficulties in the feasibility of production and application. These shortcomings are adverse 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 for the development of single-hole laparoscopy.

Technical solution

A single-hole laparoscopic surgical channel includes a housing, an instrument hole, an air inlet tube, and an exhaust tube, wherein the outer casing is composed of a cylindrical hard sheath and a soft cap that can be placed over the hard sheath. The general shape of the hard sheath main body includes a straight cylindrical shape, a thin waist tubular shape, a funnel shape and the like, and the inner and outer mouths of the hard sheath main body may be flat or oblique, and the outer mouth has a ring edge, and the common shape of the ring side includes Cap-like or flared. The hard sheath body has an intake pipe and an exhaust pipe. The hard sheath has a barrier inside, which divides the hard sheath lumen into multiple partitions, and the laparoscopic instrument can pass through and oscillate from each partition. The barrier has a plurality of branches, and the branch shape includes a beam shape, a plate shape or the like, and each branch meets or approaches each other near the center or the center of the hard sheath cross section, and the shape of the barrier includes but is not limited to a Y shape, a cross shape, and a field. Glyph. A guide plate or a guide cylinder having a sloped shape may be attached along the barrier branch to extend to one side or both sides of the barrier to facilitate access of the surgical instrument. The barrier and the inner wall of the hard sheath can be integrated, and the barrier can also be assembled into a hard sheath as a component. The hard sheath and the barrier are rigid and the materials of manufacture include, but are not limited to, polyethylene, thermoplastic polyurethane elastomer, and metal.

The soft cap is a film structure, and the film structure can be similar to a balloon, a medical rubber glove or a film bag. It has high elasticity or ultra-flexibility, and the soft cap can be freely changed in shape. In the static case, the common shape of the soft cap includes a disk shape, a cap shape, and a glove. shape. The soft cap has a plurality of instrument holes, and the instrument hole is fused with the film structure, and the instrument hole has at least one layer of air leakage preventing structure. The anti-leakage structure functionally includes an anti-leakage structure when the instrument is placed and a leak-proof structure when the instrument is not placed, and includes a fissure type, a valve type, a ring type, a flap type, and a shape including a disk. Shape, flying saucer or cone. The soft cap manufacturing materials include, but are not limited to, high molecular polymers such as silica gel, rubber, and polyethylene. The soft cap can be placed over the outer or inner mouth of the hard sheath. The soft cap and the hard sheath can be integrated into one body, and can also be assembled and used as a component separately. The assembly and fixing manner of the soft cap and the hard sheath include but not limited to the wire looping and the fixing ring fixing.

Beneficial effect

The invention has the beneficial effects that the instrument hole is directly disposed on the soft cap. Since the flexible soft cap of the present invention can be freely deformed, the instrument hole can be freely moved following the swing of the instrument, and is not limited by the shape, and the short tube structure and the base of the instrument can be discarded. The elimination of the restriction of the short tube of the instrument on the device can avoid the shortage of the short tube swing of the instrument and the shortage of the short tube of the instrument itself, and expand the scope of surgery. The invention adopts a barrier to separate different endoscopic instruments, and uses the grille to provide support for the swing of the instrument. The combination of the grille and the soft cap can replace the function of the short tube of the instrument, avoiding the crowding of the short tube of the instrument and increasing the scope of surgery. Moreover, the grille has a larger internal clearance than the short tube of the instrument, which provides more space for the instrument to swing. The invention simplifies the structure of the air leakage preventing device on the soft cap, does not need to additionally use the air leakage preventing component, reduces the volume of the surgical channel, reduces mutual interference of the instrument holes, and can use the device including the pre-bending hard device. A variety of single-hole laparoscopic instruments, a wide range of applications. The invention has the above advantages and is an innovation of the single-hole laparoscopic surgical channel.
