Endoscope retractor with measuring function and using method thereof

Abstract

The invention provides an endoscope retractor with a measuring function. An integral bent structure is adopted. A needed opening is small in diameter, other trocar cannulas are not needed, and therefore apparatuses are saved; a locking assembly is arranged, a wire retractor can be locked on other equipment during an operation to keep clamping organs stably, no specialized personnel are needed to hold the wire retractor in the whole process, so that manpower is saved; scale is formed in the wire retractor and can effectively measure the operation depth and operation scale of operative instruments, therefore, a quantitative concept is provided for an operator, and the problems are avoided that due to imaging differences, operation difficulty is high and the organs and tissues are easy to crash and injure. The invention further provides a using method of the endoscope retractor. Combined with the specific shape characteristics and structure characteristics of the retractor, a bent sequential inserting and step-by-step assembly mode is adopted, and therefore the incision size is reduced; by the supplementary means of the scale, relative sizes of an operative region can be precisely controlled, and the probability of body tissue and organ injuries is significantly reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laparoscopic drag hook with a measuring function and a usage method thereof. Background technique [0002] The surgeon inserts a small light source, camera and surgical instruments into the large incision of the keyhole, and guides the operation of the surgical instruments through the images transmitted to the monitor. This operation is called laparoscopic surgery. According to the size of the surgical site Different, can be divided into laparoscopic surgery, arthroscopic surgery, thoracoscopic surgery and so on. In laparoscopic surgery, in order to expose a larger surgical field of view to improve the safety and convenience of surgical operations, retractors are generally used in the prior art to remove the human organs that block the surgical field of view, but the existing retractors are generally straight-in type, large caliber, and need to use an additional puncture can...

Problems solved by technology

In laparoscopic surgery, in order to expose a larger surgical field of view to improve the safety and convenience of surgical operations, retractors are generally used in the prior art to remove the human organs that block the surgical field of view, but the existing retractors are generally straight-in type, large caliber, and need to use an additional puncture cannula path, which requires specialized personnel to operate, which takes up a lot of manpower and equipment; the surgeon guides the operation completely based on the monitoring imaging of the endoscopic surgical instrument, but in the monitor The image shown here is an image that has been magnified and deformed many times, which is different from the actual situation in the patient's cavity. It requires a high level of operating experience and level of the surgeon, otherwise it is easy to cause collision damage to the tissues and organs in the cavity.
