Description

Forearm lifting device for laparoscopic surgery

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a forearm lifting device for laparoscopic surgery.

Background

Laparoscopic surgery is a newly developed minimally invasive method and is a necessary trend for the development of future surgical methods. Compared with the traditional operation, the laparoscopic operation is popular with patients, especially has small scar after operation and meets the aesthetic requirements, young patients are more acceptable, and the minimally invasive operation is the general trend and pursuit target of surgical development. Currently, the golden standard of laparoscopic surgery is cholecystectomy, and most of the general surgical operations, laparoscopic surgery, are generally performed. Such as appendectomy, gastric and duodenal ulcer perforation repair, hernia repair, colectomy, splenectomy, adrenal gland resection, ovarian cyst removal, extrauterine pregnancy, hysterectomy and the like, almost all surgical operations can be adopted with the increasing perfection of laparoscopic techniques and the improvement of the operating level of laparoscopic surgeons. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. The traditional method of the retrolaparoendoscopic surgery is to make three small 1 cm incisions on the waist of a patient, insert a tubular working channel called trocar respectively, and carry out all the following operations through the three channels; and then special lengthened surgical instruments are used for completing the same steps as the open surgery under the television monitoring, so that the same surgical effect is achieved.

The advantages of laparoscopic surgery after two-hole surgery are very obvious, firstly, the trauma is very small, only 2 small holes are needed, and the scar is very small, which is more remarkable for young people and women loving beauty. Secondly, the operation is a single-knife straight-in entry, the damage to surrounding tissues is reduced to the minimum, and the chance of postoperative adhesion is reduced. Third, the patient had significantly reduced pain from post-operative wounds. Fourthly, the number of hospital stay days is small, some patients can be discharged after 2-3 days, and the patients can completely recover health and put into operation after 7 days, so that the burden cost of the patients is greatly reduced, and the turnover rate of hospital beds is accelerated. Technological advances in laparoscopic surgery have led to new developments in laparoscopic partial nephrectomy. However, the requirement of the operation is high, when the tumor is removed and the wound is sutured, the renal artery needs to be temporarily blocked by using the blood vessel blocking clamp, the bleeding amount is reduced, a clear operation field is provided, and the arterial blood flow is reopened after the operation is finished. This procedure leaves the kidneys in a warm ischemic state, severely affecting renal function, but a typical laparoscopic procedure is often long lasting, and presents a significant challenge to the manual assistant's physical requirements of holding the lens.

The forearm lifting device on the market at present has a single function, is difficult to meet users with different heights, cannot adjust the distance between the anesthesia headrest and the lifting structure, is inconvenient for protecting the arm, causes the phenomenon that the forearm lifting device is easy to collide with the lifting arm support, and often troubles people.

Therefore, a forearm lifting device for laparoscopic surgery is proposed to solve the above problems.
