Long sleeve type hand-assisted device

Abstract

The invention discloses a long sleeve type hand-assisted device. The long sleeve type hand-assisted device comprises a retractor and a sealing mechanism, and is characterized in that the sealing mechanism comprises a long sleeve and a ring, wherein one end of the long sleeve is hermetically connected to the retractor; the ring can be connected with the other end of the long sleeve and gloves. Compared with the prior art, the long sleeve type hand-assisted device has the advantages that activity limitation and easily caused fatigue caused by the fact that an assistance hand is fixed on an abdominal wall are avoided, the operation is more flexible and more comfortable, a stable long channel is established (the size of an incision of the assisted device is determined according to surgery requirements, and the hand can stretch or not into an abdominal cavity), an open instrument can be applied to a laparoscopic surgery, and a brand-new idea and an operation method are provided for a hand-assisted laparoscopic surgery.

Description

Technical field: [0001] The invention relates to a surgical instrument. Background technique: [0002] Laparoscopic surgery first establishes an artificial pneumoperitoneum, and performs surgery under the illumination of a laparoscope. It is divided into three types: complete laparoscopic surgery, laparoscopic-assisted surgery, and hand-assisted laparoscopic surgery. Hand-assisted laparoscopy refers to the laparoscopic surgery performed by inserting one hand into the abdominal cavity with a hand assistant, accounting for about 30% of laparoscopic operations. [0003] The use of the existing hand aid is: cut the abdominal wall about 7-9cm (according to the size of the operator's hand), retract the incision with a retractor, and fix the operator's wrist on the retractor with an outer ring. This kind of hand aid, because the method for fixing the wrist adopts the method of tightening, after the wrist is tightened, it is easy to cause poor blood flow in the arm, easily cause fa...

AI Technical Summary

Problems solved by technology

This kind of hand aid, because the method of fixing the wrist is tightened, after the wrist is tightened, it is easy to cause poor blood flow in the arm, easy to cause fatigue of the auxiliary hand, and then affect the doctor's surgical action

For this reason, someone invented an inflatable sealing device on the retractor. By inflating the sealed airbag to wrap the wrist tightly, the contact surface between the airbag and the wrist is large, so it can effectively alleviate the problem of poor blood flow in the arm. However, it is impossible to completely avoid tight wrapping and affect the smoothness of blood flow in the arm

In addition, when the surgical instrument needs to be replaced, the sealing mechanism can only be untied, and the pneumoperitoneum is rebuilt after the surgical instrument is replaced. In this way, it is very inconvenient to use, and the operator's hand is positioned on the retractor, which also affects the retractor. hand dexterity
