Laparoscopic instrument system for transumbilical single-hole surgery

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a peritoneoscope apparatus system for through navel single port operation.

Background

Currently, the laparoscopic technique is widely used in clinical surgery, such as urology surgery, general surgery, thoracic surgery, orthopedics, gynecology, and pediatric surgery. In the conventional laparoscopic technology, 3-5 holes with the diameter of 5-12 mm are drilled in the abdominal wall, and sleeves (trocars) are arranged in the holes and are respectively used for placing an endoscope and various surgical instruments for surgery; the sleeve plays a role of a safe channel for the safe access of an endoscope and instruments, the sleeve is provided with an interface which can be connected with a pneumoperitoneum machine, and CO2 gas is input by the pneumoperitoneum machine to expand the space of an operation part so as to be convenient for performing an operation. However, such a surgical method may leave scattered scars, which may affect the appearance of the skin.

Therefore, the single-hole laparoscopic surgery through umbilicus has been raised at home and abroad in recent years, the natural scar at the umbilical region is used as an incision to establish an operation channel, the operation effect is proved to be consistent with that of the conventional laparoscopic surgery at present, and no redundant incision is added except the natural scar at the umbilical region, so that the beautifying effect is obvious, and the good clinical application prospect is shown. Since the endoscope and the operation instrument are both in and out of the same channel in the single-port laparoscopic surgery, the problems of air tightness and instrument interference inevitably occur, and a plurality of researchers are dedicated to the design of the working channel of the single-port surgery to overcome the defects and improve the surgery efficiency, but no surgical sheath can solve all the problems so far.

The evaluation of the quality criteria of the surgical sheath includes: the installation and the removal are convenient; the air tightness is good; the degree of freedom of operation is large; can reduce the mutual interference of the instruments and other factors. In view of various shortcomings of the commercial single-hole channels which are put into use at present, a homemade glove laparoscope device for transumbilical single-hole surgery is urgently needed to be designed.

Chinese patent documents: CN106798543B, published: 2018.12.21, discloses a defogging device for a laparoscope lens, which comprises a shell, an inner container, a cover plate, a heat conducting insulating layer and a heating component; the inner container is arranged in the shell, the heat conduction insulating layer is coated on the periphery of the inner container, and the cover plate is arranged at the top of the shell and is fixedly connected with the shell or can be connected with the shell in an opening and closing manner; the heating assembly comprises a heating element, a temperature sensor and a temperature controller, the heating element and the temperature sensor are arranged on the periphery of the heat conduction insulating layer, a power line of the heating element and a connecting line of the temperature sensor extend out of the shell, and the connecting line of the temperature sensor is electrically connected with the temperature controller; be equipped with the peritoneoscope jack on the apron, and the inner chamber of peritoneoscope jack and inner bag is linked together, the inner chamber bottom of inner bag is equipped with the sponge that soaks the iodophor.

Has the advantages that: the demisting effect is good, the duration is long, and the use is more economical and practical. But the technical proposal does not relate to the improvement and innovation of the transumbilical single-port laparoscopic surgery.

Chinese patent documents: CN105726070, published: 2016.07.06, discloses a transumbilical single-hole multi-channel laparoscopic surgery sheath, which consists of a top cover, an inner sleeve, a snap ring and an outer sleeve, wherein the top cover consists of four double-layer one-way valve type working channels, a rotary buckle and a silica gel elastic membrane; the top of the inner sleeve is provided with a rotary clamping groove, an air inlet hole and an air outlet hole are arranged below the rotary clamping groove, the air inlet hole is opened at the lower edge of the inner sleeve through an air inlet pipe passing through the wall of the inner sleeve, the air outlet hole penetrates through the wall of the inner sleeve, and the inner sleeve, the clamping ring and the outer sleeve can be rotatably connected; the bottom of the outer sleeve is provided with a ring-shaped air bag, and an air bag vent pipe penetrates through the wall of the outer sleeve and penetrates out from the top to be connected with a free air bag gas injection valve.

Has the advantages that: the sleeve has adjustable length, excellent air tightness and convenient operation, and enables the single-port laparoscopic surgery to become more efficient. However, the technical scheme is more complicated when the instrument is removed after the operation, and meanwhile, the position of the laparoscopic surgical instrument in a single hole is not flexible, and in addition, the device has a complex structure.

In summary, there is a need for a laparoscopic instrument system for single-hole transumbilical surgery, which is convenient to install and remove, has good air tightness and high operational freedom, and can reduce the mutual interference of instruments, and no relevant report is found at present.
