Tension-adjustable automatic draw hook for laparoscopic puncture channel

Abstract

The invention provides a tension-adjustable automatic draw hook for a laparoscopic puncture channel. The tension-adjustable automatic draw hook comprises a linear supporting strip; an arc-shaped supporting sheet with an adjustable opening and closing angle is mounted on one side of the supporting strip through a fixing mechanism; draw hook mounting mechanisms are mounted at mounting parts arrangedat two ends of the inner side of the arc-shaped supporting sheet; and draw hook mounting mechanisms are provided with draw hook bodies of different specifications which can be selected according to the subcutaneous fat thickness of a patient. The supporting strip of a rigid structure is matched with the arc-shaped supporting sheet of a flexible structure, the supporting strip and the arc-shaped supporting sheet can be rapidly fixed through the fixing mechanism, and the opening and closing degree of the arc-shaped supporting sheet can be flexibly adjusted through the fixing mechanism, so thatthe draw hook can be suitable for suture of different minimally invasive surgery wounds, meanwhile a medical staff can independently suture the wound without an assistant, the suture difficulty of thedeep muscle fascia of the puncture channel is reduced, and the draw hook is better suitable for laparoscopic puncture minimally invasive surgery treatment.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an automatic pull hook with adjustable pulling force for a laparoscopic puncture channel. Background technique [0002] With the improvement of medical technology, minimally invasive surgery has developed rapidly. Minimally invasive surgery requires small surgical incisions, short operation time, and less soft tissue damage, so that patients can recover as soon as possible. [0003] At present, minimally invasive surgery accounts for 90% of urological surgery, among which most urological tumor surgery adopts laparoscopic or robotic surgery, and the common specifications of the puncture channel, namely TROCAR, are: 5mm, 8mm or 12mm. After the operation is completed, when suturing the deep muscle fascia of the puncture channel, the assistant needs to pull the pull hooks to the outside with both hands respectively. It requires the cooperation of multiple medical staff to...

Problems solved by technology

[0004] The object of the present invention is to provide an automatic pull hook with adjustable pulling force for laparoscopic puncture channel, which aims to solve the problem that when suturing the deep muscle fascia of the puncture channel in the prior art, the assistant needs to use the pull hook to pull it apart with both hands. The suture operation can only be completed by the cooperation of multiple medical staff, and the traditional retractor is not suitable for patients of different sizes, which increases the difficulty of suture
