Description

Electric screw-in type poking card

Technical Field

The utility model relates to an appurtenance for laparoscopic surgery especially relates to an electronic screw-in stabs card.

Background

With the development of medical technology, minimally invasive surgery with less injury and fast recovery has become very popular in the medical field, wherein laparoscopes play an important role in many minimally invasive surgeries, and most laparoscopes are delivered into the body through a laparoscope stab card.

The peritoneoscope of prior art stabs the card and constitutes by stabbing the card core and stabbing the cutting ferrule pipe mostly, stabs the card core and inserts in stabbing the cutting ferrule pipe and together puncture the mouth department in abdominal wall, because stabbing the card core and handheld and directly pierce through abdominal wall, in order to avoid causing unexpected injury to the viscera, require very high to the degree of depth and the dynamics precision of stabbing, need be accomplished by professional medical staff, the operation degree of difficulty is fairly high.

In addition, when the poking sleeve enters the abdominal wall or during the operation, the poking sleeve is easy to slide in the poking opening of the abdominal wall, which affects the operation visual field of the laparoscope and the operation. In order to avoid stabbing the gliding condition of cutting ferrule pipe, prior art stabs cutting ferrule pipe surface and is equipped with frosting face or the anti-skidding line that is used for increasing friction, the stability of stabbing cutting ferrule pipe in the abdominal cavity wall has been improved, but frosting face or anti-skidding line take place friction and extrusion with the health tissue, not only stab the mouth department to the operation and cause the frictional damage and stab a mouthful hemorrhage, bring unnecessary misery for patient, and when taking out and stabbing the cutting ferrule pipe, frosting face or anti-skidding line can cause the injury to stabbing a mouthful once more, be unfavorable for the postoperative to resume.

The laparoscopic stab cards of the prior art also suffer from various disadvantages, such as:

1. because the body tissue is soft and has elasticity, the poking card of prior art can cause abdominal cavity pressure to increase when inserting the abdominal cavity, is unfavorable for the peritoneal needle body to pierce through the abdominal cavity wall, and medical staff need puncture many times repeatedly, has caused bigger injury to patient.

2. In order to adapt to patients of different body types for use, the poking card core body and the poking card sleeve in the prior art need to reserve enough length and volume so as to ensure that the puncture depth and the puncture angle can meet the surgical requirements, but the length of surgical instruments such as a laparoscope is limited, and the length and the volume of the poking card are too large, so that the surgical field is easily influenced, and the operation is not facilitated.
