A device suitable for high ligation of the hernia sac in children with indirect inguinal hernia under laparoscopy

Abstract

A device suitable for hernia sac high ligation of laparoscopic indirect inguinal hernia in children is provided. The inner wall of a needle body is provided with a transverse channel I (7) through which a hook longitudinally slides along the needle body, an end of the transverse channel I (7) is connected with a semicircular channel (8), the semicircular channel (8) allows the pull hook (6) to rotate in the needle body, the sidewall of the needle body is provided with a receiving hole (9), a lower needle body (4) is made of shape memory alloy, a transverse channel II (10) through which the pull hook (6) longitudinally slides in the needle body is provided between the receiving hole (9) and the semicircular channel (8), an end of the lower needle body (4) may deform and enter the receiving hole (9) after reaching transition temperature, the lower needle body (4) is provided with a temperature sensor (12), and the temperature sensor (12) is connected with a display screen (13). The device is highly operable, high in safety coefficient, low in manufacture cost and higher in precision.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to a device suitable for high-position ligation of the hernia sac of an indirect inguinal hernia under laparoscopy. Background technique [0002] Indirect inguinal hernia is one of the common surgical diseases in children. The principles of diagnosis and treatment are quite different from those in adults, and the surgical methods and techniques are also unique. At present, experts in pediatric surgery at home and abroad believe that indirect inguinal hernia in children is caused by the unclosed congenital processus sheath, which is also the theoretical basis of the operation method, that is, the therapeutic purpose can be achieved by high-level ligation of the sheath-like process, instead of inguinal hernia. Tube reinforcement. Based on this theory, the currently commonly used surgical methods include high ligation of the small transverse hernia sac through the inguinal ...

AI Technical Summary

Problems solved by technology

Medical institutions at home and abroad that are currently unable to carry out laparoscopic techniques basically use the high ligation of the small transverse hernia sac through the inguinal area. This surgical method has an incision of 1.5 cm. During the dissection and separation and ligation process, the surrounding tissue may be insufficiently exposed when the hernia sac is ligated. Ligating it together will cause the testis to shift to the inguinal canal and cause the potential risk of iatrogenic cryptorchidism; in addition, the small incision open surgery destroys the anatomical structure of the groin, and may damage the spermatic cord blood vessels, nerves and cremaster muscle when stripping the hernia sac

Domestic laparoscopic high-level ligation of the hernia sac (sheath-like process) is mostly performed by suturing and ligation of the inner ring with the aid of transumbilical and paraumbilical double-empty forceps. "Hernia needle" technology and economic factors have caused certain difficulties for the operator and the child

These shortcomings are still affecting the efficacy of indirect inguinal hernia surgery in children

In recent years, a device suitable for high-position ligation of the hernia sac of an indirect inguinal hernia under laparoscopy has appeared, generally using a straight needle and an arc needle, or only using an arc needle. requirements, which reduces the safety of the operation. The high-position ligation device with high safety performance in the prior art uses magnetic components to realize the hooking and knotting of surgical lines, but the operability is poor. In addition, the magnetic components are fixedly connected to the main body parts. , the production cost is greatly increased, and the connection strength of two different parts will decrease with the use of time, which brings safety hazards
