Description

Laparoscope suspension guide needle

Technical Field

The utility model relates to the technical field of medical equipment, especially relate to a peritoneoscope suspends guide needle in midair.

Background

The laparoscopic surgery refers to a method for completing the operation through a laparoscopic instrument, and is a main mode of the gynecological and general surgical operations after decades of rapid development; the transumbilical single-hole laparoscope technology is operated by only one operation hole of about 3cm in the umbilical region, has the advantage of aesthetic property that only one scar is hidden in the umbilical region after operation, and is selected by vast female patients. However, the number and the operation angle of the operation holes are very limited, so that an assistant can hardly perform auxiliary operation and expose the operation field, and the difficulty of the operation is greatly increased. For example: in the process of carrying out laparoscopic rectal cancer operation on a female patient, because the uterus is positioned in front of the rectum, when the rectum is dissociated, an operation hole needs to be additionally opened to lift the uterus by using a clamp so as to better expose the front wall of the rectum, the sight and the operation of an operator are blocked because an instrument can occupy a narrow operation space, moreover, the clamp can only assist in lifting the uterus to expose the rectum but is difficult to form satisfactory proper tension, and simultaneously, because of the limitation of an operation incision, the lifting angle of the uterus is limited, thereby influencing the operation time and the operation quality; in extensive hysterectomy by laparoscopy, the cervical cancer may be increased by the lifting cup, and the cervical cancer is gradually abandoned by many operators, but the operation becomes harder after the operators lose the important assistance of the lifting cup for adjusting the position and the angle of the uterus. Uterine suspension can help the operator overcome these difficulties to some extent, but the completion of uterine suspension has certain difficulties. Especially under a single-port laparoscope, the difficulty of completing the suspension operation is greatly increased.

The uterus is suspended in midair also to have at present to adopt the puncture trocar, but this puncture trocar structure is more complicated, the operation is not convenient, pull the push rod often can not be fast and smoothly send into the suspension wire in the abdominal cavity in the in-service use process, moreover, pull out the back from the opposite side behind the uterus one side with the suspension wire, the suspension wire often also can not be fast and smoothly pull into in the hollow pjncture needle, also can not guarantee simultaneously that the in-process suspension wire that slowly upwards promotes and extract at the pull push rod does not drop, suspend the in midair the in-process here, it is consuming time longer, influence operation time and operation quality equally.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the existing methods for pulling uterus or other organs to obtain good exposure by using suspension operation during pelvic cavity or abdominal cavity operations such as hysterectomy through a laparoscope or a single-port laparoscope, rectal cancer and the like, but the puncture point of the conventional method is limited by operation difficulty, so that a satisfactory and flexibly-changed angle or tension cannot be provided sometimes, and even the suspension operation cannot be completed.

In order to solve the technical problem, the utility model provides a peritoneoscope suspends guide pin in midair, including guide pin body and handle, the handle is located the one end of guide pin body, the other end of guide pin body is equipped with the puncture portion, be equipped with the through wires hole that is used for wearing to establish the suspension line on the guide pin body, the through wires hole is close to the puncture portion sets up.

More preferably, a distance D between an end of the puncturing part and the threading hole is 10 to 20 mm.
