Retractor for operations

Abstract

The invention discloses a retractor for operations. The retractor includes a support; handles are installed on the left and right sides of the outer wall of the support; the inner walls of the handlesare connected to the outer wall of the support; pull rods are installed on the inner wall of the support; the outer walls of the pull rods are movably connected to the inner wall of the support; andthe outer walls of sleeve rods are movably connected to the outer walls of the handles. Through the cooperation among first extension springs, second extension springs and casings, under the action ofthe pull rods and supporting rod ears, the first extension springs and the second extension springs are under the action of crank handles, the disadvantages that draw hooks are easy to shake and cannot be adjusted during using can be improved, and therefore, more approvals can be obtained for existing retractors for operations in markets, the produce quality of the retractors for operations can be enhanced, the purchasing costs of users can be saved, the waste of computer case resources can be avoided, and the retractor for operations is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a retractor for surgery. Background technique [0002] At present, it is known that in the clinical medical operation process, an assistant needs to be added to use a surgical retractor to pull the surgical incision during a major operation, which is time-consuming and laborious during the operation of the assistant, which increases the ineffective operation during the operation. If the traction is improper during the operation, it is easy to cause damage to solid organs or hollow organs. During the operation, it is also necessary to adjust the position of the operator and the assistant, which often increases the chance of surgical infection and affects the time of the operation. In the prior art, for example, the invention patent with application number 201420748660.3 includes a body, and the body It is circular, and the body is provided with two poles, two holes wi...

Problems solved by technology

[0002] At present, it is known that in the course of clinical medical operations, it is necessary to add assistants to use surgical retractors to open the surgical incision during major operations, which is time-consuming and laborious during the operation of the assistants, which increases the ineffective operation during the operation

If the traction is inappropriate during the operation, it is easy to cause damage to solid organs or hollow organs

During the operation, it is also necessary to adjust the position of the operator and the assistant, which often increases the chance of surgical infection and affects the time of the operation. In the prior art, for example, the invention patent with application number 201420748660.3 includes a body, and the body It is circular, and the body is provided with two poles, two holes with automatic locks, a pull rope inside the automatic lock, and feet at the lower ends of the two poles, and the two poles are made of Composed of a sleeve and a solid rod, the upper end of the sleeve is provided with a height adjustment valve, one end of the pull rope is provided with a sleeve, and two movable rods are arranged inside the sleeve, and pull hooks are provided at the outer ends of the two movable rods. Although the structure of the invention is simple , but there are many deficiencies and defects. In the existing equipment, there are defects in the design of the traction rope. The connection between the traction rope and the eyelet is unstable. It is easy to make the pull hook shake when used, resulting in unstable hooking, and the pull hook cannot Adjusting the inclination angle is not conducive to the use and promotion of surgical retractors. The use function is single and requires manual adjustment by medical staff, which will easily cause work fatigue for medical staff, increase medical costs and purchase medical equipment funds, and cause waste. For these situation, in order to avoid the above-mentioned technical problems, it is necessary to provide a retractor for surgery to overcome the defects in the prior art
