Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific drawings.

[0033] like figure 1 , figure 2 , image 3 and Figure 4 As shown, the poking balloon dilator includes an expansion balloon 3 for inserting into the space under the laparoscopic surgery incision and inflating or inflating the soft tissue under the laparoscopic surgery to form the space for laparoscopic surgery. It is used to form a hole for inserting surgical instruments and form a hole to inflate or fill the expansion balloon 3 with a poking ferrule 1. It is used to assist the push of the expansion balloon 3 into the space under the incision through the laparoscopic surgical incision The rod 2 and the hollow tubular quick-fill valve 4 used to quickly inflate the expansion balloon 3 with the syringe. A sealing structure 11 and an inflation port 13 with a switch 12 are provided at the tail of the poking ferrule rod 1 . The expansion balloon 3 is connected with the opening...

Abstract

The invention discloses a trocar balloon expander which comprises a trocar, a push rod, an expansion balloon and a one-way inflation tube, wherein the expansion balloon which can expand after being inflated for manufacturing an endoscopic surgery space is arranged at the end of the trocar; the push rod which is used for ejecting the expansion balloon, so that the expansion balloon is implanted into a clearance under an incision through a relatively small surgery incision after deforming; the one-way inflation tube is connected with an inflator pump and can inflate the expansion balloon, so that surrounding tissues of the slot clearance under the surgery incision pushed and the clearance under the incision expands and enlarges to form the endoscopic surgery space. An expansion balloon taking device is arranged at the front end of the push rod; and the expansion balloon can be separated from the trocar end and taken out through a trocar inner cavity after surgery space expansion is finished. The trocar balloon expander is simple in structure and convenient to use, is applied to a few of endoscopic surgeries, has the function of the balloon expander in the early stage, can be used for manufacturing the endoscopic surgery space; the expansion balloon at the trocar end can be separated out after the endoscopic surgery is finished, so that the trocar balloon expander has the function of the trocar for use in the surgery, and is ingenious in structure, high in usability, safe and reliable.

Description

technical field [0001] The invention relates to a peritoneal puncture device (punching card), which belongs to the technical field of medical instruments. Background technique [0002] In some laparoscopic operations, such as kidney, ureter, and cystoscopic operations, because there is no physiological cavity in the surgical site, it is necessary to artificially expand the skin after incision before the operation to create a surgical space for subsequent operations. When expanding the space under the skin incision, it is necessary to safely and effectively move the soft tissue under the incision without causing damage to the surrounding organs. [0003] The paracentesis is a necessary instrument for laparoscopic surgery, and it is used to provide a convenient passage for laparoscopic surgery to enter and exit the operating space. [0004] At present, the instrument for moving the subcutaneous soft tissue is separated from the abdominal puncture device in clinical practice. ...
