Holding type operation retractor

Abstract

The invention provides a holding type operation retractor. The retractor comprises two grips, wherein upper ends of the two grips are closed toward the center, and front ends of the two grips are hinged together through an anchor bolt; a tension spring is arranged between the two grips, and is sleeved in the middle of the anchor bolt; and the front ends of the grips are movably connected with replaceable extension hooks. The holding type operation retractor has the characteristics of reasonable structure and convenience in operation and is suitable for various surgical operations, and the holding type grips are adopted, so that an operative incision can be opened to a proper angle by applying force to the grips through palms. The holding type operation retractor is convenient to operate and saves labor, is convenient for single operation of a doctor, so that the working efficiency can be improved, and the stability of surgical operation can be maintained.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical pinch grip type surgical retractor. Background technique [0002] During the surgical operation, the retractor is a commonly used medical device. The retractor can expand the surgical incision or wound to reveal the deep operation area, which is convenient for the doctor to perform the operation and keep the operation going smoothly. Existing retractors are mainly divided into three types: the first is a pull hook type retractor, the traditional pull hook is a group of two, held by a nurse with both hands, hooking the both sides of the surgical incision or wound, pulling Open enough space in the body for the doctor to operate, and the nurse needs to expand, reduce the surgical incision or wound, and change the expansion angle according to the doctor's intention and requirements at any time, so as to facilitate the doctor's operation in the patient's body, which requires good communic...

Problems solved by technology

Existing retractors are mainly divided into three types: the first is a pull hook type retractor, the traditional pull hook is a group of two, held by a nurse with both hands, hooking the both sides of the surgical incision or wound, pulling Open enough space in the body for the doctor to operate, and the nurse needs to expand, reduce the surgical incision or wound, and change the expansion angle according to the doctor's intention and requirements at any time, so as to facilitate the doctor's operation in the patient's body, which requires good communication between the doctor and the nurse and tacit understanding, so as to keep the doctor's intention accurately and quickly, and at the same time, the nurse must maintain the same stretching posture throughout the operation, which is prone to fatigue; the second is a fixed retractor device, which can hold the surgical incision or wound It is opened at a fixed angle and width, so that doctors can operate in the patient's internal space. It usually uses screws to adjust the opening angle of the surgical incision. When the doctor needs to change the opening angle of the surgical incision, the position of the screw must be fixed again. Waste the precious time of operation, simultaneously the retractor of this structure is not flexible enough, is not easy to change the opening angle of surgical incision; In the same way, the operation site is expanded through the cooperative force between the thumb, index finger or other fingers, and the size and angle of the applied force are changed to meet the intention and requirements of the surgeon. Intensive expansion of the surgical site can easily cause muscle fatigue, stiffness or even cramps in the hand, which cannot maintain the stability of the operation and affects the efficiency
